[0038] Figure 1 The main structure diagram of the connector anti-cracking structure showing the embodiment of the present application. Figure 2 The partial enlarged view of the connector anti-cracking structure showing the embodiment of the present application. Figure 3 The structure diagram of the pin 100 of the connector anti-cracking structure showing the embodiment of the present application. As Figure 1 、 Figure 2 or Figure 3As shown, the anti-interference structure of the connector includes: a base 200 and a plug pin 100, wherein the base 200 is provided with a plurality of plug holes penetrating along the radial direction of the base 200, the plug holes are stepped holes, and the aperture of the first end face of the plug hole adjacent to the base 200 is larger than the aperture of the second end face of the plug hole adjacent to the base 200. There are a plurality of the above-mentioned plug pins 100, the number of the plug pins 100 matches the number of the plug holes, and the plug pins 100 are plugged into the plug holes one by one. The portion of the first end face of the plug pin 100 adjacent to the base 200 is clearance-fitted with the plug hole, and the portion of the second end face of the plug pin 100 away from the base 200 is interference-fitted with the plug hole. It should be noted here that the cross section of the plug hole along the axial direction of the plug hole is "T"-shaped. It should also be noted here that the radial direction of the base 200 is the axial direction of the base 200.

[0039] The anti-cracking structure of the connector of the embodiment of the present application includes two parts: a base 200 and a plug pin 100. The base 200 can be a plastic part. A plurality of plug holes are provided on the base 200, and the plurality of plug holes are all arranged in a stepped hole shape. When the plug pin 100 and the base 200 are plugged in, the plug pin 100 will first be inserted from the first end face side of the base 200. The hole diameter of the plug hole here is larger than the diameter of the plug pin 100. Therefore, the first end face side of the base 200 will not receive the expansion force generated by the plug pin 100 due to interference, so that the force point of the plastic part is changed from the end face surface to the inside, thereby improving cracking. In summary, the anti-cracking structure of the connector of the embodiment of the present application adds a "T"-shaped step to the first end face of the base 200 by setting the plug hole in a stepped shape, thereby preventing the end face from cracking during the assembly process of the first end face of the base 200 and the plug pin 100.

[0040] Here, it should be noted that, in a possible implementation, the base 200 is columnar. Furthermore, in a possible implementation, the base 200 is cylindrical, and the boss 110 is annular.

A latch 210 is provided on the outer wall of each plug pin 100, and the latch 210 is arranged circumferentially around the outer wall of the plug pin 100. The latch 210 is located in the socket at the boss 110, and the latch 210 and the socket at the boss 110 are interference fit (i.e., plugged). Therefore, the fitting point of the latch 210 and the socket can be transferred from the original end face to the current place where the boss 110 is provided, that is, the fitting point of the latch 210 and the socket is transferred from the original thin wall to the current thick wall, so that the thickness of the connection is increased.

[0042] In a possible implementation, a groove is provided on the side of the pin 100 where it is not inserted into the jack, and the groove is circumferentially provided around the outer wall of the pin 100.

[0043] Furthermore, in a possible implementation, the groove is provided adjacent to the first end face of the base body 200, and the groove is coaxially arranged with the pin 100.

The diameter of the retaining portion 220 is set larger than the aperture diameter of the pin 100. By providing the retaining portion 220, the insertion amount of the pin 100 can be accurately controlled. When setting the snap 210, the insertion position of the snap 210 can be made to be at the boss 110.

[0045] Here, it should be noted that in a possible implementation, the jack can be a round hole, and the pin 100 can be cylindrical.

When the pin 100 is inserted into the jack, the inclined surface side of the snap 210 faces the jack. By providing the inclined surface, the insertion of the pin 100 into the jack can be made simpler and easier.

[0048] Here, it should be noted that in a possible implementation, the pin 100 includes a first cylinder and a second cylinder. Among them, the first cylinder and the second cylinder are coaxially arranged, and both the first cylinder and the second cylinder are cylindrical structures. The end face diameter of the first cylinder is smaller than the diameter of the first end face of the jack away from the boss 110.

[0049] Here, it should also be noted that in a possible implementation manner, the pin 100 is integrally formed, and the base body 200 can be integrally formed.

[0050] In a possible implementation manner, the jack includes a first through hole and a second through hole that are communicated with each other. The first through hole and the second through hole are coaxially arranged, and the aperture of the first through hole is larger than that of the second through hole. The first through hole is opened on one side of the first end face of the base body 200. The length of the first through hole is greater than or equal to the distance from the first end face of the boss 110 to the first end face of the base body 200, and the length of the first through hole is less than or equal to the distance from the second end face of the boss 110 to the first end face of the base body 200. That is, one end of the first through hole away from the first end face of the base body 200 is located between the first end face and the second end face of the boss 110. Wherein, the first end face of the boss 110 is arranged on the same side as the first end face of the base body 200, and the second end face of the boss 110 faces away from the first end face of the boss 110.
