[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model aims to provide a filter test electrode to solve the problems existing in the prior art, is convenient for use on automatic test equipment, and can be adapted to filter products of various sizes.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-Figure 5 As shown, the present embodiment provides a filter test electrode, including a mounting seat 2, a contact 1, a reciprocating assembly 3 and a fixed element 4. The contact 1 can be detachably mounted on the upper end of the mounting seat 2 and is suitable for use on automatic testing equipment. A plurality of grooves 6 are provided on both sides of the contact 1. The inner walls of the grooves 6 are used to contact the pins 5 of the product to be tested. The use of the grooves 6 can achieve compatibility with products with different pin spacings. The mounting seat 2 is installed on the fixed element 4 through the reciprocating assembly 3, and the mounting seat 2 can move back and forth, and can closely contact the pins 5 of the product to be tested under the action of the reciprocating assembly 3, so as to facilitate the testing of the pins 5.

[0026] Specifically, a first threaded hole 8 is provided on the upper end surface of the mounting base 2, and a second threaded hole 7 is provided on the contact 1. The contact 1 is installed on the mounting base 2 by passing a bolt through the second threaded hole 7 and the first thread in sequence, which facilitates the installation and removal of the contact 1.

[0027] Two through holes 10 are arranged side by side at the lower end of the side wall of the mounting seat 2, and a reciprocating component 3 is installed in each through hole 10. The number of through holes 10 can also be adaptively changed according to actual needs; there are two fixing elements 4, which are respectively located at the two ends of the through hole 10 in the length direction, and the two fixing elements 4 are respectively used to install the two ends of the reciprocating component 3 to realize the installation of the reciprocating component 3.

[0028] The reciprocating assembly 3 includes an optical axis 11 and two springs 12. The optical axis 11 passes through the through hole 10, and the two ends of the optical axis 11 are respectively installed on the two fixed elements 4. A limiting ring is provided in the through hole 10. The two springs 12 are both sleeved on the optical axis 11, and the ends of the two springs 12 that are close to each other are respectively installed on both sides of the limiting ring. Each fixed element 4 is provided with a limiting groove, and the ends of the two springs 12 that are far away from each other are respectively installed in the limiting grooves of the two fixed elements 4, and then the two springs 12 are installed through the limiting ring and the limiting groove, and the pin 5 is indirectly pressed by the spring 12 for testing. During the test, a movable mechanical structure is used to move the mounting seat 2 between the pins 5 of the product to be tested, so that the mounting seat 2 drives the contact 1 to continue to move toward the pin 5 until the contact 1 contacts the pin 5. At the same time, during this process, as the mounting seat 2 and the contact 1 translate, one of the springs 12 is compressed, and the compressed spring 12 applies a compression force to the mounting seat 2, thereby achieving a compression force from the contact 1 to the pin 5, which is convenient for parameter testing. Among them, the optical axis 11 can also be replaced by a linear slide rail, etc., as long as the mounting seat 2 can be guided and compressed.

[0029] There are two contacts 1 and two mounting seats 2 , and each mounting seat 2 is correspondingly mounted with one contact 1 . The two mounting seats 2 are arranged along the radial direction of the through hole 10 , so as to facilitate the compression of the four pins 5 .

[0030] The fixing element 4 is a fixing frame.

[0031] The cross section of the groove 6 is semicircular, and those skilled in the art may also select a groove 6 with a flat inner wall or other shapes, as long as the use requirements can be met.

[0032] The upper end of the mounting seat 2 is also provided with a receiving groove, and a limiting step 9 is also provided in the receiving groove. One end of the contact 1 can be embedded in the receiving groove and contact the limiting step 9. When the two contacts 1 are installed, the two receiving grooves are located on the side away from each other.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
