[0029] Refer to the following Figures 1 to 5 A terminal detection socket according to an embodiment of the present invention is described.

[0030] A terminal detection socket according to an embodiment of the present invention, such as Figures 1 to 5As shown, the terminal detection socket includes a base 100, a probe 200, and a guide block 300. The base 100 is provided with a mounting hole 110, and the probe 200 is installed in the mounting hole 110. The guide block 300 is installed on the base 100. The guide block 300 is provided with a receiving cavity 310. The position of the receiving cavity 310 corresponds to the position of the mounting hole 110. The receiving cavity 310 receives the probe 200 and exposes at least a portion of the side surface of the probe 200 to form a contact surface. Specifically, when installing the terminal detection socket, the probe 200 is first installed in the mounting hole 110 of the base 100, so that the receiving cavity 310 of the guide block 300 is aligned with the probe 200. When the guide block 300 is installed on the base 100, the receiving cavity 310 receives the probe 200. The receiving cavity 310 is provided with an outward opening. The side surface of the probe 200 is at least partially exposed at the opening, forming a contact surface for contacting the terminal 400. When testing terminal 400, terminal 400 moves downward, making contact with and squeezing the contact surface of probe 200 from the outside. This squeezing force elastically deforms probe 200, which has a resilient force that resists deformation, ensuring full contact between probe 200 and terminal 400, ensuring effective testing. The contact surface is located on the side of probe 200, replacing the traditional needle tip contact test with a needle body contact test on the side of probe 200. This facilitates testing of the inner wall of the ring terminal 400 and protects both probe 200 and terminal 400.

[0031] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, a bending portion 210 is provided at the top of the probe 200, and the bending portion 210 is bent toward the inside of the accommodating cavity 310. The terminal 400 moves downward to contact the probe 200, and the bending portion 210 is bent toward the inside of the accommodating cavity 310. The bending portion 210 forms an inclined angle relative to the probe 200. The terminal 400 moves downward along the inclined angle and contacts the contact surface of the probe 200, squeezing the contact surface of the probe 200. The probe 200 rebounds toward the side where the terminal 400 is located under pressure, so that the probe 200 and the terminal 400 are in full contact, preventing poor contact and ensuring the detection effect. The provision of the bending portion 210 can guide the terminal 400, so that the terminal 400 can move smoothly downward to contact the contact surface, avoiding direct collision between the contact surface of the terminal 400 and the probe 200, and protecting the terminal 400 and the probe 200.

[0032] Reference Figure 1 、 Figure 4 and Figure 5According to some embodiments of the present invention, the depth of the accommodating cavity 310 is greater than the thickness of the probe 200, so as to provide reserved space for the elastic deformation of the probe 200. The depth of the accommodating cavity 310 is greater than the thickness of the probe 200, and the probe 200 can move in the accommodating cavity 310, providing reserved space for the elastic deformation of the probe 200 after being compressed. Specifically, when the terminal 400 is tested, the terminal 400 moves downward to contact and squeeze the contact surface of the probe 200. The probe 200 is elastically deformed by the pressure from the terminal 400 and moves toward the accommodating cavity 310. The depth of the accommodating cavity 310 can provide reserved space for the deformation and movement of the probe 200, protect the probe 200, and avoid damage to the probe 200.

[0033] Reference Figure 1 、 Figure 4 and Figure 5 According to some embodiments of the present invention, the guide block 300 includes a mounting plate 330 and a detection head 320 disposed on the mounting plate 330, and a receiving cavity 310 is disposed on the side of the detection head 320.

The side of the detection head 320 is provided with a receiving cavity 310, and the receiving cavity 310 accommodates the probe 200. The side surface of the probe 200 is at least partially exposed to the outside to form a contact surface, and the contact surface is used to contact with the terminal 400 to detect the terminal 400. It can be understood that in some embodiments, the side wall of the detection head 320 is configured to have an inclined angle. Specifically, the diameter of the detection head 320 gradually decreases in the direction away from the mounting plate 330. With reference to Figure 4 and Figure 5 The top diameter of the detection head 320 is the smallest, which makes it easy for the ring to be mounted on the detection head 320 to detect the terminal 400 on the inner wall of the ring.

The mounting plate 330 is mounted on the base 100 through the cooperation between the mounting holes 110 and the positioning holes 331. Specifically, in some embodiments, the positioning holes 331 are configured as threaded holes, and the connecting holes 120 are configured as through holes. Countersunk screws pass through the connecting holes 120 of the base plate and are threadedly connected to the positioning holes 331, thereby achieving a threaded connection between the mounting plate 330 and the base 100. It is understood that in some other embodiments, the positioning holes 331 are configured as through holes, and the connecting holes 120 are configured as threaded holes, which can also achieve a threaded connection between the mounting plate 330 and the base 100.
