[0035] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.
[0036] Example:
[0037] like Figures 2 to 7 As shown, this embodiment provides a probe with a limiting structure, including: a needle rod 1 and a needle 2; one end of the needle 2 is connected to one end of the needle rod 1; the needle 2 is used to insert into the test port; a limiting step 101 is set at one end of the needle rod 1 connected to the needle 2, and the limiting step 101 is used to limit the insertion depth of the needle 2.
[0038] The probe further comprises a needle sleeve 3 , which is sleeved on the needle rod 1 ; a welding wire structure 301 is provided at one end of the needle sleeve 3 , and when the needle sleeve 3 is sleeved on the needle rod 1 , the welding wire structure 301 can be connected to the needle rod 1 .
[0039] When inserting the probe, the needle 2 is first inserted into the test port 501. When inserted to a certain extent, the limit step 101 will abut against the edge structure of the test port 501, so that the probe cannot be inserted further. At this time, the needle 2 is completely located in the test port, thereby preventing the probe from being inserted too deeply. After the insertion is completed, the test component can be connected to the probe through the welding wire structure 301 on the connecting needle sleeve 3, thereby realizing the connection test.
[0040] The needle rod 1 and the needle head 2 are both cylindrical, and the needle head 2 and the needle rod 1 are coaxially arranged. The end of the needle head 2 away from the needle rod 1 is set to be conical or hemispherical. When it is set to be conical, the bottom circle radius of the conical structure is 0.03mm. The end of the needle rod 1 away from the needle head 2 is set to be hemispherical, and the radius of the hemispherical structure is 0.45mm. The limiting step 101 is a truncated cone structure. The height of the truncated cone structure is 0.05mm. The length of the needle rod 1 is 28.4mm, and the length of the needle head 2 is 8.5mm. The diameter of the needle rod 1 is 1.02mm, and the diameter of the needle head 2 is 0.35mm.
[0041] The present embodiment also provides a test socket 4, comprising a plurality of the above-mentioned probes with a limiting structure. According to the number of test ports on the connector socket 5, a plurality of probes are distributed on the test socket 4 corresponding to the test ports on the connector socket 5, and the length of the needle 2 of the probe extending from the test socket 4 is kept consistent, so as to ensure that when the test socket 4 is plugged into the connector socket 5, the length of the plurality of probes inserted into the test ports is consistent.
