[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0023] Example: Please refer to Figure 1-5 A female connector needle seat comprises a first needle seat 1, a second needle seat 2, a third needle seat 3, a fourth needle seat 4, a probe 11 and a spring needle 31.
[0024] The first needle seat 1 is fixedly connected to the fixture, and the second needle seat 2 is fixedly connected to the lower end of the first needle seat 1. The lower end of the first needle seat 1 is provided with a first boss, and the upper end of the second needle seat 2 is provided with a first groove. The first groove and the first boss are loosely matched, and the first needle seat 1 and the second needle seat 2 cooperate to fix the probe 11.
[0025] The fourth needle seat 4 is floatingly arranged at the lower end of the second needle seat 2. The floating arrangement belongs to the prior art. The floating arrangement is as follows: the fourth needle seat 4 is screwed on the second needle seat 2 by screws. Four springs are arranged between the second needle seat 2 and the fourth needle seat 4 (not shown in the figure, the prior art can be used). In this embodiment, the screws are equal height screws 5, and the springs are compression springs. The fourth needle seat 4 has a floating state and a compression state. The floating state means that the spring is not compressed when there is no external force, and the distance between the fourth needle seat 4 and the second needle seat 2 is the maximum value. The compression state means that the spring is compressed when there is an external force, and the distance between the fourth needle seat 4 and the second needle seat 2 is reduced.
[0026] The third needle seat 3 is fixedly connected to the lower end of the second needle seat 2 and is located between the second needle seat 2 and the fourth needle seat 4. A second boss is provided at the lower end of the second needle seat 2, and a second groove is provided at the upper end of the third needle seat 3. The second groove and the second boss are clearance-matched, so that the third needle seat 3 can be better aligned with the second needle seat 2 in a fixed position relationship, so that the third needle seat 3 is conveniently buckled on the second needle seat 2.
[0027] The upper end of the fourth needle seat 4 is provided with a third groove, and the third groove is matched with the clearance of the lower end of the third needle seat 3 to ensure the smoothness and accuracy of the fourth needle seat 4 when floating up and down.
[0028] A third boss 41 is provided at the lower end of the fourth needle seat 4 , and a cavity for buckling with the female connector is provided at the lower end of the third boss 41 , so that the fourth needle seat 4 can be buckled on the female connector.
[0029] The spring needle 31 is located on the third needle seat 3 and passes through the third needle seat 3. The upper end of the spring needle 31 is located in the third needle seat 3. The lower end of the spring needle 31 passes through the third needle seat 3 and is exposed at the lower end of the third needle seat 3. The fourth needle seat 4 is provided with a first needle hole for the spring needle 31 to pass through.
[0030] One end of the probe 11 is fixedly connected to the first needle seat 1, and the other end passes through the second needle seat 2 and comes to the third needle seat 3 to contact the upper end of the spring needle 31. The upper end of the spring needle 31 may be provided with a matching groove that matches the clearance of the lower end of the probe 11, so as to facilitate the contact between the probe 11 and the spring needle 31.
[0031] When the fourth needle seat 4 is in a floating state, the lower end of the spring needle 31 does not appear from the first pinhole; when the fourth needle seat 4 is in a compressed state, the lower end of the spring needle 31 appears from the first pinhole. In this embodiment, the spring needle 31 is an oblique spring needle, which is convenient for inserting the lower end of the spring needle 31 between the spring openings in the female connector when the female connector needle seat is connected with the female connector, so that the spring in the female connector has a certain opening, so that the spring needle 31 and the female connector maintain a stable connection, which is conducive to the smooth transmission of electronic signals.
[0032] The material of the first needle seat 1, the second needle seat 2, the third needle seat 3 and the fourth needle seat 4 is TORLON4203, so the overall weight of the female connector needle seat is light, and the TORLON4203 material is wear-resistant and heat-resistant, and has excellent thermal stability and good electrical insulation, which can prevent the high current generated in the working state from breaking down the female connector needle seat, thereby extending the service life of the female connector needle seat.
[0033] Working principle of this embodiment: This embodiment provides a female connector needle seat, the first needle seat 1 fixes the entire female connector needle seat to the fixture, the probe 11 is fixedly connected to the first needle seat 1, and the first needle seat 1 and the second needle seat 2 cooperate to complete the fixation of the upper and lower ends of the probe 11, the third needle seat 3 is loaded with a spring needle 31, and the front and rear left and right directions of the spring needle 31 can be limited. After the first needle seat 1 and the second needle seat 2 complete the fixation of the probe 11, the loaded spring needle 31 is placed on the third needle seat 3. The third needle seat 3 of the leaf needle 31 is buckled on the lower end of the second needle seat 2 and fixedly connected, the probe 11 contacts the spring needle 31, and the upper and lower directions of the spring needle 31 are limited under the action of the probe 11, and then the fourth needle seat 4 is locked to the lower end of the second needle seat 2 by the equal height screw 5, and four compression springs are installed between the fourth needle seat 4 and the second needle seat 2. The clearance between the third groove of the fourth needle seat 4 and the third needle seat 3 can ensure the smoothness and accuracy of the fourth needle seat 4 when floating up and down. Under normal conditions, the fourth needle seat 4 is in a floating state under the action of the spring, and the third boss 41 of the fourth needle seat 4 is lower than the protruding part of the spring needle 31, thereby protecting the spring needle 31 from being damaged in the non-working state; in the working state, the female connector needle seat relies on the cavity of the fourth needle seat 4 to snap onto the female connector, and the female connector needle seat as a whole is in a compressed state and exposes the spring needle 31. The oblique design of the spring needle 31 makes it convenient for the lower end of the spring needle 31 to be inserted between the spring openings in the female connector when the female connector needle seat is mated with the female connector, so that the spring in the female connector has a certain amount of opening, so that the spring needle 31 and the female connector maintain a stable connection, which is conducive to the smooth transmission of electronic signals. The female connector needle seat fixes the probe 11 and the spring needle 31 through four needle seats, and uses the contact and cooperation between the spring needle 31 and the probe 11 to complete the transmission of electronic signals. It can be used for testing a test fixture of a camera module with a female connector, expanding the use market of the test fixture, increasing the applicability of the test fixture and the diversity of the camera modules that can be tested.
