[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0027] A side contact probe according to an embodiment of the present application, as Figures 1-7 shown, includes: a probe body 1, one end of the probe body 1 is formed with a first threaded section 11, and one end of the probe body 1 is connected to a conductive block on a needle bed of a testing device through the first threaded section 11; the other end of the probe body 1 is connected with an elastic connection unit 2, and the elastic connection unit 2 is used in cooperation with the outer surface of a pin 3 of a product to be tested. It should be noted that the working principle between the probe body 1 and the pin 3 of the product to be tested is a prior art and will not be elaborated here.
[0028] Specifically, the other end of the probe body 1 is formed with a mounting portion 13, and the elastic connection unit 2 is connected to the mounting portion 13; the mounting portion 13 is formed with a fitting cavity 131, and the elastic connection unit 2 is fitted with the fitting cavity 131 to make the installation of the elastic connection unit 2 more convenient.
[0029] In one embodiment, as Figures 3-7 shown, the elastic connection unit 2 includes a plurality of elastic members 21, the plurality of elastic members 21 are arranged on the mounting portion 13 at a preset interval, each elastic member 21 has a fixed section 211 and a contact section 212, and the fixed section 211 and the contact section 212 are connected; the fixed section 211 of the elastic member 21 is arranged on the outer wall of the mounting portion 13, and the contact section 212 of the elastic member 21 is located in the fitting cavity 131; a plurality of contact sections 212 form a contact hole for cooperating with the pin 3 of the product to be tested;
[0030] The elastic member 21 further includes a guiding section 213. The fixing section 211 is connected to the contact section 212 through the guiding section 213. The guiding section 213 is inclined, which is convenient for guiding the pin 3, enabling the pin 3 to cooperate with the contact hole. The contact section 212 and the fixing section 211 form the elastic member 21 with a preset elasticity through the guiding section 213. When the pin 3 is inserted into or pulled out of the contact hole, the contact section 212 can be extruded or reset under the external force of the pin 3.
[0031] The elastic member 21 further includes an end section 214. The end section 214 is connected to the other end of the contact section 212. The end section 214 is inclined in the opposite direction of the contact hole, avoiding jamming with the pin 3 and facilitating the insertion and extraction of the pin 3.
[0032] In one embodiment, as Figures 3-7 shown, the elastic connection unit 2 further includes a plurality of blocking members 22 and a bushing 23. A blocking member 22 is provided between two adjacent elastic members 21. Limiting grooves 221 that cooperate with the corresponding elastic members 21 are respectively formed on both sides of the blocking member 22, making the cooperation between the elastic member 21 and the blocking member 22 more stable;
[0033] The bushing 23 is detachably connected to the other end of the probe body 1. The bushing 23 positions a plurality of blocking members 22 on the mounting portion 13; the bushing 23 has through holes at both ends, facilitating the insertion and extraction of the pin 3.
[0034] As an example, internal threads are formed on the bushing 23, and external threads that are threadedly connected to the internal threads are formed on the other side of the probe body 1. The bushing 23 is threadedly connected to the probe body 1.
[0035] When testing the electrical functional performance of the product, the upper needle bed of the testing device descends, and the probe is inserted into the pin of the product. When the probe contacts the pin on the product, the elastic connection unit on the probe opens. When reaching the specified height, the elastic connection unit of the probe measures the contact with the product pin.
[0036] It should be noted that the terms used here are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.
