[0019] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-Figure 3As shown, a connector socket with a new sealing structure is a connector for a servo motor for outputting current of the motor, comprising a socket housing 1, a dust cover 2 and a plurality of pins 3 arranged in the socket housing 1. One end of the socket housing 1 is sleeved in the dust cover 2. A fixing member 4 is embedded in the socket housing 1. The fixing member 4 is provided with a mounting hole matched with the pins 3. A grounding collar 5 is arranged on the side of the fixing member 4 away from the dust cover 2. The grounding collar 5 is embedded in the side wall of the socket housing 1, and one end of the grounding collar 5 is engaged with one of the pins 3. The dust cover 2 comprises an integrally arranged sleeve 21 and a cover plate 22. The socket housing 1 is an annular pipe, whose annular side wall is sleeved with the sleeve 21, and one end thereof is in contact with the cover plate 22. In order to further ensure the sealing between the socket housing 1 and the dust cover 2, a sealing line 23 is arranged on the inner wall of the sleeve 21.

[0021] like Figure 4 As shown, the inner wall of the socket housing 1 at the port is provided with a collar groove 11 for installing the ground collar 5. The inner wall of the socket housing 1 is also provided with a retaining ring 12, and a retaining groove 13 is provided on the retaining ring 12. The retaining ring 12 is used to prevent the fixing member 4 from moving forward and backward; the retaining groove 13 is used to prevent the fixing member 4 from rotating. In the present application, the socket housing 1, the retaining ring 12, and the retaining groove 13 are integrally formed.

[0022] In this application, the pins 3 include four, namely one pin A31 and three pins B32, which are arranged in a quadrilateral, and the pin A31 and the pin B32 which is farthest from it are placed on the same midline. The diameter of the pin A31 is 2.5 mm; the diameter of the pin B32 is 3.4 mm.

[0023] The grounding clamp ring 5 is an arc-shaped ring, one end of which is provided with a clamping member 51, and the clamping member 51 is engaged with a clamping groove provided on the pin A31.

[0024] In the present application, the socket housing 1 and the plug pin 3 are both metal parts, the fixing part 4 is an injection-molded insulator, and the fixing part 4 is an integral injection-molded part. Compared with the existing connector socket, the present application converts the two insulators originally installed inside into an injection-molded integral injection-molded insulator, which simplifies the processing process. That is, by fixing the socket housing 1 and the plug pin 3 in a plastic injection mold, and then directly injecting the integral injection-molded insulator (fixing part 4), it replaces the original cover plate and insulator, and also reduces the production process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
