What are crimp dies
To know what crimp dies are and what they are for, it is necessary to focus on the meaning of crimping and how it is made. Crimping is a very common operation in the field of wiring and involves the connection between a cable and its termination or its connector. The union is both strictly physical, as the cable will be joined to the target element, and electrical since once the connection is correctly established, the passage of electric current (or data) can be verified. To carry out the crimping operation, a special tool is required, i.e. the crimping pliers which, in order to function, require dies placed at the ends: it is the dies, in fact, that are in contact with the cable and with the element to be connected and thanks to them, crimping can occur. The matrices must always be positioned in pairs on the gripper, respecting the correct positioning and making sure to insert the locking pin to ensure its position.
The crimping dies, therefore, are accessories that must be added to a special pliers and that change according to the type of crimp to be made: there are in fact different types and choosing the right one will depend exclusively on your needs and the material to be crimped. .
How crimp dies work
But how do crimp dies work? All the dies, once applied to the pliers, allow the crimping operation through a real mechanical crushing that allows the cable to remain blocked on the connector due to the pressure exerted. If the gripper and dies are used correctly, mechanical squeezing allows for a good electrical connection. Very often, however, crimping alone is not sufficient and this occurs above all in conditions where external agents (such as water or humidity) could compromise the connection: in these circumstances it is also preferable to proceed with a soldering using a tin alloy.
In any case, once crimping has been performed, the connection is irreversible and it is no longer possible to disconnect the cable from the previously connected connector. Even the pliers (or presses) for crimping are not all the same but have some differences: for example, the crimping profile (oval, hexagonal, trapezoidal and ...) can change and some models are suitable for crimping particular materials and in particular conditions (for example, we find pliers that are ideal for connecting even non-insulated joints or for working under certain ranges of electrical voltage). As already mentioned, therefore, we always recommend that you consult an expert before purchasing in order to be sure you are making the right choice.
Types of crimp dies
Let's analyze in detail some types of crimping dies:
- Crimping Die for Pre-Insulated Eyelet: These are dies for eyelet and terminal connector. These matrices can be used for cables with sheath and differ in crimping intervals (expressed in mmq). They can generally be used with a pneumatic and / or electric crimping tool;
- Die for cable lug and bare eyelet. They are matrices similar to those seen previously, but the connection is made with a bare eyelet. It can be used with pneumatic and / or electric crimping tools, these also differ from each other in terms of crimping intervals.
- Crimping matrix for coaxial connectors (ideal for this type of cable). They differ in intervals and the shape of the crimp profile.
- Matrix for crimping flag faston (pre-insulated or not) and matrix and ferrules: these are specific matrices for crimping certain connectors.
- Matrices for pre-insulated ferrules and eyelets: these are matrices used to crimp both elements.
These are some examples of the most common dies, but you can find several on the market, each specific to the connector to be crimped. In any case it is important that these accessories are made according to precise safety standards, to avoid unpleasant unforeseen or dangerous inconveniences.
