What Are The Issues To Consider When Choosing A Terminal Block?

Many people are unfamiliar with the terminal, because although we can use and see it in normal times, we don't know what it is and what it does. Let's take a look at the function of the terminal and how to choose the terminal.

Terminals

Function of terminal block

The terminal is a piece of metal sealed inside the insulating plastic, with holes on both ends for inserting wires, and is mainly used for connecting a large number of wires. If the wires need to be connected or disconnected from time to time, you can connect them with terminals at this time and disconnect or connect them at any time.

How to choose a connection terminal

Nowadays, there are many manufacturers of terminal blocks, some of which are good, and of course there are also some chaotic. When choosing a professional terminal block, in addition to its brand and price, we must also consider: in terms of appearance

At present, most of the production terminals are sampling tests, and good terminals must have due process, that is, the surface is flat, no scratches, no burrs at the corners, and uniform wall thickness; more importantly, the matching of the plug and the needle seat High degree, there will be no phenomenon of too low or too high insertion force.

In terms of material

Generally speaking, materials can be divided into two categories: first, plastic parts, which must have good flame retardancy, that is, the flame retardant rating of UL94V-0; the simpler test method here is to ignite with an open flame, if the plastic parts If the open flame is extinguished, it indicates that the terminal has good flame retardant performance.

Next is the crimping frame. Many users often say whether the terminal is copper or not, but here is the crimping frame. Generally speaking, the copper frame is more angular than the iron ore texture.

Hands-on test

The reason for the poor contact of some terminals on the market is that the screw torque is not up to the requirement, so the screw torque of the terminal is particularly important, so it is advisable to test it once.

These are brief introductions to the related knowledge of the terminal, I hope it will be helpful to you.
