Pliers for crimping wire: methods of using

To contact electrical wires was quality and contributed to feed for a long time power to the desired object, it is necessary to perform connection with the appropriate instruments. Pliers for crimping wire connections provide sufficient area. Only required to choose the right size of the matrix and consumables - ferrules and sleeves.

Crimping pliers: professional and household tools

Electrician - sphere, requiring flawless performance of the rules, follow the exact technology, the use of special tools. Particularly noteworthy are the connection wires. Any inaccuracies and half-measures necessarily lead to injury or rupture of contacts.

Long gone twisted. They are strictly forbidden technical maintenance rules for electrical consumers. Today, there are special tools - pliers to crimp the wires. They consist of a handle and a replaceable matrix, the choice of which must take into account the target compound and the cable cross-sections.

For technical characteristics and a method for operating mites can be divided into two categories:

• mechanical (manual);
• automatic (actuated by actuators).

It carried out the division and within categories. Mechanical pincers can be for household and professional. With the help of home runs crimped wire with a small cross-section: 1-2.5 mm - copper; 2.5 mm - aluminum. Possible to use the cable cross-section 4 mm for high power household appliances.

Crimping tool for wire cross-section of 6 mm or more using a powerful, professional. Thick power wires and cables for industrial applications crimped automatically.

The main types of crimping pliers for terminals

The need to apply for crimping wires may occur in two situations: in the case of preparation live parts for fixing the terminals of various electrical equipment and when connecting wires and cables. Depending on the purpose of using one or the other crimping tool. On the basis of mites design features can be divided into two main types:

• operating on the principle of pliers;
• diaphragm.

The first option is the most common. Ticks are crimped on both sides by a pair of pliers are distinguished by a special notch on the lips, which allow you to make connections as durable.

Ease of use of this kind of ticks is that they do not need to choose the position of tips, you can perform an action with any party. Some appear problematic in situations where the liner does not fit into the matrix. In this case, you need one more mites.

Useful advice! Before performing such electrical work must ensure in accordance sized instrument and consumables. As a way out - is to buy a universal model of mites with a set of matrices, which are fixed on a special cassette.

Diaphragm press for tips of wires carry crimping sleeves with four or six sides, and they adapt to the cable thickness. Crimping the end in this manner it is characterized by a high density.

For a special kind is attributed Crimper. While many so-called all crimping pliers, in this article, this concept will be applied to the instrument with a computer and Internet connection. On the specifics of the device - further into the article material.

Methods of Using the press jaws for crimping ferrules

Work on crimping wires may have a constant or sporadic. In everyday terms is more characteristic of the second embodiment. In such cases there is no need to purchase universal pressing jaws for crimping wires. It should pick up the tool a narrow focus, which will help solve specific tasks.

To the core functionality of this type of instrument are:

1. Crimping sleeves. Necessary for this type of crimping pliers are different in shape and size of the matrix. As an additional structural element flange may be present. Its presence will perform better connection.
2. Removal of the insulating layer. With the mites can remove the desired portion of the insulating coating, without directly damaging the conductor. It is important to set the size. If the experience is not enough, it is better to buy an instrument, where the size is set automatically. These models are more expensive, but provide a high-quality work.
3. Crimping tips. Presses for crimping wires have a special rod, which in the course of action is placed on a separating seam. The device is designed to work with non-insulated and brass wires.
4. Working with twisted pairs. This crimping tool is put into a special wire connector.

Only properly selected tool will perform a quality connection.

Hydraulic press tool for crimping wires

During the implementation of electrical works, hydraulic mechanisms are used extensively. The main components of such presses tongs are:

• pens;
• axis;
• head;
• matrix.

In hydraulic crimping pliers wire head can be closed and open. In the closed first embodiment, the stopper opens, the matrix is ​​pulled, the wire is laid to the sleeve, locked, and only after that the crimp is made. The design with an open head does not need to carry out preparatory actions, so the pressure test runs much faster.

Each model gidrokleschey designed for a specific size range of wire sizes. The maximum rate is 400 mm. In everyday life, these veins do not apply, but with the tip of wire crimp 6mm gidrokleschami work comfortably. However, there is a danger pinch.

Useful advice!To work with a soft wire is better to buy hydraulic press with limiter. He will avoid overloading the tool.

To visualize the consequences pinched hydraulic press, is to understand the mechanism of its action.

Because of the rocking handle plunger (plunger pump) produces translational return motion, it creates a certain pressure under the influence of which the oil enters the cylinder. Oil moves the cylinder that, in turn, creates a pressure in the matrix, and it is necessary to force acts on the sleeve.

Tool for crimping wires of the Internet

Stable operation of any cable system consists of several indicators. First of all, it is the quality of the cable material. This is followed by the professional level of specialists who carry out installation. What matters is the technical condition of the equipment. Totally unreasonable in the last number called the quality of connections.

It contacts often cause unstable or weak signals. Avoid the cabling problems associated with non-wired, possible only by using a special tool - the press for crimping pliers, which are called "Crimper".

Performance of any cable connection always begins with the removal of insulation from the ends of the wires. For this purpose, there is also a separate type of instrument, called "stripper". With it, the upper layer is removed, there is no danger of damaging veins. Alternatively, you can purchase Crimper, which has elements that allow to produce sweep. This hole, with one side having a blade. Once the wire and rotate it once, you can get the desired result.

Crimper crimping and stripping wires are widely used by specialists during assembly of structured cabling systems.

Crimper for crimping: specificity design application

Crimper principle of action for crimping wires the same as in dvuhgubochnyh mites. The difference is that the latter is clamped sleeve, and Crimper - plugs. More precisely, not produced crimp in its standard sense, but there is displacement contacts, which leads to tightly adjusting. This tool is designed to work with twisted pairs.

Before performing crimping Crimper be sure to spend an even pruning untwisted conductors. If this is not done, a uniform position in the connector will not work to achieve, and it will affect the quality of the crimp. You can do this using ordinary pliers, but it does not always produce the desired result.

Many ticks model crimping internet cables are equipped with special forceps. They are blades which are closed tightly by pressing the tool handles.

Important!Before cutting the straightened wire is required to be set in a desired sequence to compound (a color basis).

There are many varieties Crimper. The principle of operation for all models are the same, but there are differences in the standards of connectors. On the crimping tool casing for the cables are always present designation, indicating the purpose of the instrument. For example, RJ 45 designated as 8P. This indicates the standard and maximum number of pairs. RJ 11 - 6P, the maximum number of pairs does not exceed 6.

Compression pliers for crimping wire RJ 45

RJ45 connectors are one of the most used in the field of computer networking. RJ - is Registered Jack, a standardized network interface. The housing of the device significantly more RJ 11. Last should not be used for computer connections, it is used when laying telephone cables. The inner content and the functioning of the principle of these two kinds of connectors almost identical.

Crimping pliers for RJ45 cable lugs are selected in accordance with the marking. With regard to the general requirements, it is necessary to pay attention to such indicators:

1. The weight. Small is likely indicative of the application for the production of enough strong materials, so long life should not count. Overly heavy will contribute to the rapid tiring hands.
2. Form handles. It must be ergonomic, comfortable to grip.
3. The presence of defects. Traces dents and other physical damage may be a consequence of incorrect assembly. It is worth paying attention to the line of contact blades, sponges: even minor deviations will affect the quality of the crimp.

Among the most popular models of handheld press pliers twisted pairs include Hanlong HT-500. Designed as a tool for connector RJ45, and RJ11 to RJ12 and options. Crimper equipped with blades for cutting and stripping. The price of the product - 1250-15000 rubles. Model attributed to the professional.

cheap mites 5bites LY-T568R is sufficient demand. They are also designed for three types of connectors are blades. Products lighter weight - 340 g, less durable (for reviews of users in social networks). They can be bought for 450-500 rubles.

Variety of tips for crimping stranded wires

In the foregoing article a lot of information material about the tool, with the help of which you are crimped. But it is equally important to choose the right tip for the quality of the connection. They, too, there are several types. Let us consider the products for stranded wires.

Characteristics, scope of use. Varieties of devices. Types strippers. Popular models of famous brands.

Copper tips. Outwardly, they represent the copper tube, flattened on one side, in which there is a hole for the bolt. These lugs are divided into elements uncoated (TM) and tin-coated (TML). The latter are used in those cases when it is necessary to make a connection with high anti-corrosion properties. Crimp wires lugs of this type may be carried out by any kind of mite, the matrix size corresponding section.

Brass with inspection hole. This embodiment is not subject to crimping, soldering is used for joining. Information placed for general information purposes only. Externally lugs similar to the previous ones, differ only by the presence of holes through which the position viewed conductors.

Aluminum. Aluminum wires are crimped caps of the same material. Externally, they are totally similar to copper, labeled AF.

Important! Before crimping aluminum conductors to be processed quartz-vaseline paste. It prevents the appearance of okislovoy film.

Press tool for crimping of this type can be used as hydraulic and manual.

Pin. They operate via permanent connections. Abbreviated NSHVI - a tip of the pin sleeve insulated. Peeled wire insulation are inserted into the sleeve and crimped with pliers.

The tip on the wire crimp: annular, hook, fork

To connect to terminals need to use tips that will ensure the most reliable connection. The main condition - they must correspond to the type of terminal. To date, there are three main types of these tips:

1. Ring. Their purpose - connection to the screw terminal blocks. Providing large contact surface is one of the advantages of this type of terminals. It used a similar option for both temporary and permanent connections to low voltage networks.
2. "Hook" type tips. They create a contact surface for a quarter less than the ring. To swage the electric cable of this type ferrules and joining the terminal does not need to completely unscrew the fastening screw. These tips often used for temporary connections, or in situations where unscrew the screw for any reasons it is impossible.
3. Fork. These tips have a contact surface, which is 50% less than that of the ring. It is for this reason they are often used for temporary connections, requiring a constant change of contact.

There are other types of tips, but they are specific and are used rarely, mostly professional electrician for installation of complex circuits.

Domestic production tool: crimping pliers wire KW

Among the tools of domestic production noteworthy press crimping pliers ITC wires. The main company is located in Kaluga. Especially popular are the STF kits, which include a template for crimping insulated and non-insulated terminals, and sets the PTS is included in the license template.

STV set consists of the following substantive items:

• Press ticks;
• 5 numbered matrices;
• plastic case.

Ticks are equipped with a mechanism for the rapid replacement of the matrix. As a material used for manufacturing stainless steel tool. The design of the press there lever to unlock. When correctly selected size of the matrix molding process may not be completed, whereby handles are locked in an intermediate position. In such cases, the starting point of the tool is returned by means of a lever.

It should be noted that the elongated handle ticks, it allows you to crimp both hands. Five matrices allow to choose an option, it is necessary for a certain type of terminal.

STF is set as 5 matrices. Press ticks for terminals not equipped with a device for quick replacement, so you should use the hex wrench. The process of replacing the matrix takes a long time, sometimes even more than the crimp. Included STF (unlike PTS) there are two additional screw matrices in case of loss or damage in use.

Important! When inserting the matrix, so as not to make a mistake, you must pay attention to the size of the slots, large leaves aside pens, smaller - in the direction of the head mites.

Crimping pliers wires: how to choose

The variety offered by manufacturers ticks crimping terminals, lugs quite easily "lost". Description of products in the shops are full of positive characteristics. Navigate and find the right tools to help model the following tips:

1. Selection should begin with a clear definition of tasks. It is because of them it is necessary to select the size and functionality of pressing tongs. If you are coming repeated crimping, stripping contacts and cutting wires is necessary to get a universal version of the tool.
2. For crimping and connecting the cables with a large cross-section is more convenient to use a hydraulic mechanism.
3. Important criteria are price and manufacturer of the instrument. Proven brands always reliable. Low cost is likely to be an indicator of the fragility of use.
4. When buying you should definitely check out the press-pliers to crimp lugs for defects and to evaluate the quality of assembly: when by visual inspection to identify possible dents and chips, check the correctness of the contact line of the blades, the position of the handles.
5. Be sure to pay attention to the shape of the handles. The presence of the recesses for gripping promotes more reliable retention of the tool.
6. It is recommended to hold the pliers in the hands. Any inconvenience related to the shape and weight, be sure to show up.

Performing crimping wires with their own hands

Theoretically swage of wires is not a difficult process. The presence of a tool corresponding consumables and some physical effort - all that is needed. In reality, the compounds may leave much to be desired, and sometimes even have to repeat the procedure. This sequence of actions during swage of wires will be useful to those who are willing to perform a termination own hands:

1. It is necessary to hold the cable processing, remove the insulation by means of a special device, leaving a margin of 0.3 - 0.5 cm. If trimming knife was made nonetheless, make sure that the vein is not affected. If damaged land have to be removed.
2. Wear on the wire piece thermal insulating sheath. Open part of the wipe with alcohol, degrease and apply to it a special paste.
3. Set in the matrix desired size and sectional view of the handpiece. Tip enter through.
4. the cable core in the expanded state should as far as possible to put in the tip.
5. Crimper produce pressing the knob. Once it clicks compression is completed. Handles must return to the starting position.
6. The length of the braid to return to the place of connection, warm it building a hairdryer.

There is an opinion (and some do) that perform crimping and easy without special tools, using common pliers. To a certain extent this is permissible, but only for a small section of wire and make a temporary connection, if necessary. Snug fit terminals to conductor can provide only matrix. And then excluded from entering the air, water, oxidation of the metal compound functioning long and reliably.
