Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to an electrical connector testing device. Background Technology

[0002] Connectors are indispensable electronic components in various electrical and electronic systems. With the development of connectors, when the solder joint gap is too small, conventional electrical test probes, due to their excessive size, cannot perform electrical performance tests on the connectors, thus affecting production efficiency. Furthermore, when conventional electrical test probes apply pressure to the solder joints for testing, the excessive force can easily cause deformation and damage, thus affecting product quality. Utility Model Content

[0003] To address the above problems, this utility model provides an electrical connector testing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The present invention relates to an electrical connector testing device, including a fixed base, a first conductive spring group, and a second conductive spring group. The first conductive spring group and the second conductive spring group are disposed on the fixed base. The first conductive spring group includes a plurality of first conductive springs, and each first conductive spring is provided with a first connecting piece that contacts and connects with the first solder pin of the connector. The second conductive spring group includes a plurality of second conductive springs, and each second conductive spring is provided with a second connecting piece that contacts and connects with the second solder pin of the connector.

[0005] Preferably, the first conductive spring group and the second conductive spring group are arranged parallel and symmetrically on the fixed base.

[0006] Preferably, the mounting base is provided with a first mounting port and a second mounting port. The first mounting port has a plurality of first slots on both sides, and a plurality of first conductive springs are respectively disposed in the first slots.

[0011] The beneficial effects of this utility model are as follows: This utility model relates to an electrical connector testing device. It uses a first conductive spring and a second conductive spring instead of an electrical testing probe, reducing manufacturing costs. The product structure is simple and easy to mold. The first and second conductive springs make contact with the connector's solder feet, thereby reducing the downward pressure on the solder feet and minimizing the possibility of solder foot deformation. Furthermore, the dimensions and spacing of the first and second conductive springs can be varied according to the solder foot dimensions of the connector being tested, adapting to various connectors, especially those with densely packed solder feet, thus improving product testing compatibility.

[0027] Please see Figure 1-9 As shown, this utility model relates to an electrical connector testing device, including a fixed base 1, a first conductive spring group 2, and a second conductive spring group 3. The first conductive spring group 2 and the second conductive spring group 3 are respectively arranged parallel and symmetrically on the fixed base 1. The first conductive spring group 2 includes a plurality of first conductive springs 21, and each first conductive spring 21 is provided with a first connecting piece 213 that contacts and connects to the first solder pin 41 of the connector 200. The second conductive spring group 3 includes a plurality of second conductive springs 31, and each second conductive spring 31 is provided with a second connecting piece 313 that contacts and connects to the second solder pin 42 of the connector 200.

[0028] During testing, the connector 200 is inserted into the insert card 300. The first conductive spring group 2 and the second conductive spring group 3 are aligned with the first solder pin 41 and the second solder pin 42 of the connector 200, respectively. The connector testing device 100 is used to deform the first connecting piece 213 to contact the first solder pin 41, and to deform the second connecting piece 313 to contact the second solder pin 42, thereby performing the connector electrical performance testing. The connector electrical performance testing is divided into two parts:

[0029] 1. Voltage test: Connect connector 200 to the test circuit for a certain period of time and apply a current higher than the normal operating voltage. The current path is from the first conductive spring group 2 or the second conductive spring group 3 to the terminal of connector 200 and then to the plug card 300 to test whether the connector can work normally.

[0030] 2. Current path: from the first conductive spring group 2 or the second conductive spring group 3 to the terminal of the connector 200, the plug card 300 exits the circuit connection. Each spring and the terminal in the connector 200 are regarded as a group. Check whether there is a connection between the groups. If not, it is a good product.

[0031] Furthermore, the fixing base 1 is provided with a first mounting port 11 and a second mounting port 12, which respectively penetrate through the fixing base 1. The first mounting port 11 has several first slots 111 on both sides for mounting first conductive spring pieces 21, with each first conductive spring piece 21 disposed in a corresponding first slot 111. The second mounting port 12 has several second slots 121 on both sides for mounting second conductive spring pieces 31, with each second conductive spring piece 31 disposed in a corresponding second slot 121.

[0032] Furthermore, the first conductive spring 21 includes a first fixing part 211, the width of which matches the width of the first fixing part 111. The first conductive spring 21 is engaged within the first locking position 111 via the first fixing part 211. The lower end of the first fixing part 211 has a first connecting part 212, which has a downwardly curved first connecting piece 213 for contacting and connecting with the first solder foot 41. The first connecting piece 213 is elastic; when the first conductive spring 21 presses down on the first solder foot 41, the first connecting piece 213 deforms upwards, reducing pressure on the first solder foot 41 and thus preventing deformation of the first solder foot 41, protecting product quality.

[0033] Furthermore, the second conductive spring 31 includes a second fixing part 311, the width of which matches the width of the second fixing part 121. The second conductive spring 31 is engaged within the second locking part 121 via the second fixing part 311. The lower end of the second fixing part 311 has a second connecting part 312, which has a downwardly curved second connecting piece 313 for contacting and connecting with the second solder foot 42. The second connecting piece 313 is elastic; when the second conductive spring 31 presses down on the second solder foot 42, the second connecting piece 313 deforms upwards, reducing pressure on the second solder foot 42 and thus preventing deformation of the second solder foot 42, protecting product quality.

[0034] This utility model relates to an electrical connector testing device. It uses a first conductive spring 21 and a second conductive spring 31 instead of an electrical testing probe, reducing manufacturing costs. The device has a simple structure and is easy to mold. The first conductive spring 21 and the second conductive spring 31 make contact with the solder pins of the connector 200, thereby reducing the downward pressure on the solder pins and minimizing the possibility of solder pin deformation. Furthermore, the dimensions and spacing of the first conductive spring 21 and the second conductive spring 31 can be varied according to the solder pin dimensions of the connector 200 being tested, adapting to various connectors 200, especially those with densely packed solder pins, thus improving product compatibility.

[0035] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
