[0002] Existing chip sensor sockets, as shown in Figure (1), generally consist of a claw spring structure terminal (A) placed inside a tubular terminal (C) to form a stable contact with the PIN pin (B) of the sensor chip.
[0003] As the number of pins on chips increases and their size grows, the insertion and extraction forces required for these pins become increasingly greater, making operation very inconvenient. Utility Model Content

[0007] Preferably, the probe (11) is disposed inside the ring (13) or a portion of the probe (11) extends outward from the ring (13).
[0008] Preferably, the end of the probe (11) that contacts the PIN needle (22) is shaped like a plum blossom.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] like Figures 2-3 As shown, the easy-to-plug chip connector provided in this embodiment includes a substrate 33 and terminals; the terminals include a probe 11 and a probe tube; the probe 11 and the probe tube are slidably disposed; the substrate 33 is provided with terminal holes; the terminals are inserted into the terminal holes. Those skilled in the art will understand that the probe 11 and the probe tube are both conductors; the substrate 33 is an insulator; when the PIN pin 22 of the chip 21 is inserted into the terminal hole and pressed against the probe 11 to form a passage, because the probe 11 is slidably disposed within the probe tube, the PIN pin 22 will not be damaged by the forceful insertion of the chip 21. Furthermore, because the PIN pin 22 is directly pressed against the probe 11, this effectively avoids the problem of insertion and removal difficulties caused by the number and size tolerances of the PIN pins 22.
[0017] Furthermore, the terminal also includes a spring 12; the probe tube includes a ring 13 and a base plate 14; the base plate 14 is fixed to one end of the ring 13; the spring 12 is disposed within the ring 13; one end of the spring 12 is fixed to the base plate 14, and the other end is fixed to the probe 11. Those skilled in the art will understand that when the PIN pin 22 is pressed against the probe 11, the spring 12 will compress, thereby protecting the PIN pin 22 from damage. Simultaneously, the elastic force of the spring 12 ensures a more stable contact between the probe 11 and the PIN pin 22, thus improving the stability of the terminal connection. In addition, it effectively avoids the problem of ineffective contact between the PIN pin 22 and the claw spring in the prior art due to positional reasons, resulting in momentary signal interruption.
[0018] Furthermore, the probe 11 is disposed within the ring body 13 or a portion of the probe 11 extends outward from the ring body 13.
[0019] Furthermore, the end of the probe 11 that contacts the PIN pin 22 is shaped like a plum blossom. Those skilled in the art will understand that the plum blossom-shaped probe 11 can form multiple points of contact with the PIN pin 22, thereby further improving the stability of the connection.
[0020] Furthermore, the terminal also includes solder balls 15; the solder balls 15 are fixed to the base plate 14 and exposed outside the terminal hole. Those skilled in the art will understand that the solder balls 15 are used to connect to the PCB board.
[0021] Furthermore, the terminal hole comprises a guide hole 31 and a clamping hole 32; the guide hole 31 is disposed at one end of the clamping hole 32, and the two are coaxially arranged; the guide hole 31 is flared, with one end opening larger than the other end; the diameter of the clamping hole 32 is the same as the diameter of the guide hole 31 at the end with the smaller diameter. Those skilled in the art will understand that when the PIN pin 22 is inserted, guided by the guide hole 31, the PIN pin 22 of the chip 21 can be quickly inserted into the terminal hole, while preventing the PIN pin 22 from breaking during insertion.
[0022] Furthermore, the terminal is fixed inside the clamping hole 32.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
