Background technique

As shown in Figure 1, a kind of traditional testing button mechanism comprising PCBA board 3 ' is plugged in PCBA board 3 ' and is in The testing piece 2 ' of bending and test lead 4 ' are also equipped with testing button 1 ' in PCBA board 3 '.When pressing testing button 1 ', test The middle part of 1 ' push to test piece 2 ' of button swings 2 ' free end of testing piece along its bending part and contacts with test lead 4 '.

Traditional test button mechanism has ratio for testing piece welding point location, testing button positioning and the deformation of testing piece Compared with strict requirements, once testing piece pad locating bias (PCBA aperture tolerance is larger, be easy to cause the situation), test is pressed Pressure point changes under button, and product will appear difficult test or normally closed property connects test point (product cisco unity malfunction), conventional measurement The testing piece screen resilience for trying button mechanism is on the weak side, and the risk that the normally closed property of test point is connected is larger, these can all directly affect product Overall quality.

Utility model content

The purpose of the utility model is to provide a kind of leakage protecting plug testing button structures, and testing button is greatly reduced and goes out Existing normally closed risk, operation accuracy are high.

To achieve the above object, the utility model provides a kind of leakage protecting plug testing button structure, including test is pressed Button, testing piece and PCBA board, the testing piece both ends are mutually fixed with PCBA board, and testing piece includes being located therein and and PCBA board Spaced apart elastic piece, elastic piece further include two bottom end mutual conductions, top be free end and the contact towards PCBA board Piece is set in PCBA board there are two the top arranged for interval with contact chip and one-to-one test lead, and testing button is that setting exists Structure in the middle part of elastic piece and for pressing elastic piece towards PCBA board direction.

The testing button includes sequentially connected press section, the first limit as a further improvement of the utility model, Portion, axis body and the second limiting section are respectively equipped with the first through hole passed through for the axis body and second logical on elastic piece and PCBA board Hole, the elastic piece and PCBA board are between the first limiting section and the second limiting section.

It is removable grafting between second limiting section and the second through-hole as the further improvement of the utility model Cooperation.

As the further improvement of the utility model, the both ends of the testing piece are insert-connecting plate；Testing piece is in free shape The end of two insert-connecting plate extends towards outside under state, and the angle of the two extending direction is at an acute angle, and elastic piece is a flat surface； It is set in PCBA board there are two the slot for insert-connecting plate insertion, the extending direction of two slots is parallel；Elastic piece with It is elastic connection between the insert-connecting plate at both ends.

As the further improvement of the utility model, connected between the elastic piece and insert-connecting plate by bending sheet body, Testing piece is integral type metal structure, and bending sheet body is equipped with the salient point with PCBA board point contact.

As the further improvement of the utility model, two contact chips are mutually gradually remote from bottom end to top orientation From the top of contact chip is bent outward with respect to its middle part；Contact chip is elastic construction.

As the further improvement of the utility model, including shell, the PCBA board and testing piece are located in shell, institute Testing button is stated equipped with press section, press section is located at outer side of shell.

Beneficial effect

Compared with prior art, the advantages of the leakage protecting plug testing button structure of the utility model are as follows:

1, since testing piece both ends are mutually fixed with PCBA board, when pressing testing button, by being located at connecing on elastic piece Contact is in contact to realize the test function of leakage protecting plug with the test lead in PCBA board, and the fixed part of testing piece is from tradition One become be arranged symmetrically two, contact chip is that reciprocating linear is mobile relative to the movement routine of test lead, relative to tradition The camber line of swing mode is mobile, its more easily calculating at a distance from test lead of the contact chip of linear movement in process of production can The dimensional accuracy for more easily controlling testing piece, reduces the time of production or assembling process alignment；And testing piece and PCBA board Between fixed part using be arranged symmetrically two, force part can be dispersed, prolonged the service life, and be greatly reduced test by There is normally closed risk because of testing piece local fatigue in button, and operation accuracy is high；

2, the first limiting section being located through on testing button, axis body and the second limiting section between testing piece and PCBA board It realizes, the function of the existing operation of testing button, and has the function of positioning, to reduce additional component, reduce cost, and survey Positioning between test piece, PCBA board and testing button three is more acurrate；

3, due to testing piece in a free state two insert-connecting plate end towards outside extend, the two extending direction Angle is at an acute angle, then after two insert-connecting plates are inserted into the slot of two PCBA boards respectively, slot makes two insert-connecting plates be parallel to each other, then Elastic piece in testing piece arches upward upwards, after testing piece and PCBA board are connected by testing button at this time, testing button On the first limiting section the elastic piece to arch upward is flattened again, pretightning force is generated between elastic piece and button at this time, can to survey The pressing for trying button provides resistance, facilitates its reset, improves its feel, and the second limiting section can be made to be tightly attached in PCBA board, It prevents from shaking；

4, the salient point and PCBA board point contact that bending sheet body is equipped with, so that the face of bending sheet body and PCBA board be avoided to connect Touching reduces the interference to contacts other in PCBA board；

5, contact chip is elastic construction, and two contact chips are mutually gradually distance from from bottom end to top orientation, contact chip Top bent outward with respect to its middle part, when the test end in contact in contact chip and PCBA board, contact chip can be generated gradually Elastic deformation increases the contact area of contact chip and test lead, while also making the pressing feel of testing button softer.

Through the following description and in conjunction with the attached drawings, the utility model will become more fully apparent, these attached drawings are for explaining this The embodiment of utility model.
