Description

A kind of EPS test needle beds

Technical field

The utility model is related to EPS tests more particularly to a kind of EPS test needle beds.

Background technology

Nowadays the technique of test needle bed is the important procedure of product test in procedure for producing, and test process is very crucial, to be examined The precise positioning and stability and high current poor contact considered in test process are damaged caused by instrument, equipment and product, Procedure quality is paid the utmost attention to, while also to remove the efficiency and the stability problem that consider to test.

Utility model content

The purpose of this utility model is to be directed to above-mentioned present situation, provides a kind of EPS test needle beds.

The technical solution adopted in the utility model：A kind of EPS test needle beds, including needle holder body, the needle holder body tool There is insert port, along the insert port edge cavity that horizontal extension is formed into the needle holder body, is set on the outside of the cavity There is fixing groove, the shrapnel group of contact insert pin is equipped in the cavity, the cavity is divided into two points of cavitys symmetrical above and below, described Shrapnel group includes being plugged in the shrapnel for dividing cavity described in two respectively, described that cavity is divided to include on the first of horizontal direction extension The left and right ends of wall, first upper wall arcuately extend to form arc groove outward respectively, and the two sides of the shrapnel are blocked respectively It closes in the arc groove, the front end of the shrapnel upsweeps and is inserted into the fixing groove.

The effect of the utility model is：So that contact pin is accurately aligned, and can also be contacted well by high current, no There is phenomena such as poor contact, fever, improve product quality and production efficiency, to save certain manpower and materials, reduces weight The expense of new production tooling.

Description of the drawings

Fig. 1 is a kind of structural schematic diagram of EPS test needle beds of the utility model；

Fig. 2 is a kind of side views of EPS test needle beds of Fig. 1.

Specific implementation mode

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality It is novel, it is not intended to limit the scope of the utility model.

As shown in Figure 1, a kind of EPS test needle beds provided by the utility model, including needle holder body, needle holder body, which has, to be inserted The outside of entrance, the cavity 1 that inside horizontal extension is formed along insert port edge, cavity 1 is equipped with fixing groove 2, is equipped with and connects in cavity Touch the shrapnel 3 of contact pin.

Cavity 1 divides for upper cavity 11 and lower chamber 12.Shrapnel 3 includes being arranged to exist in the upper shrapnel 31 of upper cavity 11 and setting The lower shrapnel 32 of lower chamber 12, upper shrapnel 21 is identical with lower 22 shape of shrapnel, all has arc section.

It is illustrated by taking upper cavity 11 as an example.Upper cavity 11 includes the first upper wall 100 that horizontal direction extends, the first upper wall 100 left and right ends arcuately extend to form arc groove 101 outward respectively.

Upper shrapnel 21 is arranged along the length of upper cavity 10, also, the left and right side of upper shrapnel 21 is fastened on arc groove respectively In 101.

As shown in Fig. 2, the front end of upper shrapnel 21 upsweeps and is inserted into fixing groove 2.And the front end of arc also has There is guiding role, contact pin is made naturally to be inserted into cavity 1.

It should be noted that in the case where being not inserted into contact pin, upper shrapnel 21 and the most short spacing of lower shrapnel 22 are slotting The half of needle thickness.

The utility model enables contact pin accurately to align, and can also be contacted well by high current, does not contact It is bad, fever phenomena such as；By test, 60A electric currents product below very stable can be tested, the production of equivalent amount Product reach reduction testing time, improve product quality and production efficiency, and to save certain manpower and materials, reduction is made again Make the expense of tooling.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.

Claims
