Description

TECHNICAL FIELD

[0001] The utility model relates to a dustproof, dust-removing connector base assembly. BACKGROUND

[0002] The circular connector is an important electronic component for interconnecting between the case and the cable for signal transmission between systems. With the rapid development of aerospace, the requirements for the circular connector are also increasing. The conventional circular connector is usually provided with a plastic dustproof cover or a customized metal dustproof cover for protecting dust, dirt and other impurities. The product cannot be automatically dustproof when installed on the case. The protective cover needs to be removed every time for use, which is inconvenient. Especially in some review environments, the protective cover cannot be removed by people and needs to be installed by robots. Therefore, the conventional connector cannot meet the use requirements under complex conditions.

[0003] In order to improve the dustproof effect of the connector under complex conditions, a pin connector and a pin-male connector connecting structure are disclosed in CN220291203U. An elastic pad is arranged on the pin connector, and a groove is arranged on the elastic pad to allow the pin to pass through. The external water vapor and dust enter the female connector. However, the dust on the pin cannot be removed, and the dust on the pin will also enter the female connector when the pin is inserted. SUMMARY

[0004] To solve the above technical problems, the utility model provides a dustproof, dust-removing connector base assembly.

[0005] The utility model is realized by the following technical schemes.

The front cover is further provided with a dust-removing assembly. A sealing sleeve is arranged at the end of the through hole in the wire sealing body.

[0007] The dust-removing assembly comprises a dustproof pad, an intermediate base and a dust-removing pad stacked in the front cover in sequence. A plurality of cylindrical holes corresponding to the positions of the through holes in the front cover are arranged in the dustproof pad and the dust-removing pad. A trapezoidal hole corresponding to the positions of the through holes in the front cover is arranged in the intermediate base. The small diameter end of the trapezoidal hole is connected to the cylindrical hole in the dust-removing pad. A dust cover is arranged in the dustproof pad. The cylindrical hole in the dust-removing pad is in interference fit with the pin.

[0008] One end of the cylindrical hole in the dustproof pad is further provided with a circular ring platform extending into the through hole in the front cover. The outer wall of the circular ring platform is attached to the inner wall of the through hole in the front cover.

[0009] The dust cover is a flexible disc, and a plurality of cuts are formed on the disc from the center to the radial direction.

[0010] The opposite ends of the through holes in the upper base and the lower base are respectively formed as stepped holes, the supporting spring ring is installed in the stepped hole on the upper base, and the other end of the supporting spring ring extends out of the upper base and is arranged in the stepped hole in the lower base.

[0011] The supporting spring ring is a cylinder, a plurality of elastic pieces are arranged on the inner wall of the supporting spring ring, and the elastic pieces are connected to the supporting spring ring at one end adjacent to the lower base and are inclined along the center of the supporting spring ring at the other end.

[0012] The end of the through hole in the sealing body is formed as a stepped hole with a diameter decreasing from inside to outside, and the middle part of the sealing sleeve is formed as a circular ring groove with a width same as that of the through hole at the outermost end of the sealing body.

[0015] In the drawing: 1 - front cover, 2 - dust pad, 3 - intermediate base, 4 - dust pad, 5 - upper base, 6 - lower base, 7 - sealing body, 8 - sealing sleeve, 9 - supporting spring ring, 10 - dust cover. DETAILED DESCRIPTION

[0016] The technical scheme of the utility model will be further described below, but the scope of protection is not limited to the description.

[0017] A dustproof and dust-removing connector base assembly includes a front cover 1, an upper base 5, a lower base 6 and a sealing body 7 connected in sequence, and a plurality of corresponding through holes are uniformly formed in the front cover 1, the upper base 5, the lower base 6 and the sealing body 7. Figure 1 As shown in the figure, the front cover 1 and the dust pad 2 are fixed by adhesion, the dust pad 2 and the intermediate base 3 are fixed by adhesion, the intermediate base 3 and the dust pad 4 are fixed by adhesion, the dust pad 4 and the upper base 5 are fixed by adhesion, the supporting spring ring 9 is fixed in the inner cavity by adhesion through the upper base 5 and the lower base 6, the lower base 6 and the sealing body 7 are fixed by adhesion, and the sealing body 7 and the sealing sleeve 8 are assembled by interference fit.

[0018] Further, the dustproof assembly comprises a dustproof pad 2, an intermediate base 3 and a dust removal pad 4 which are sequentially stacked in the front cover 1. The dustproof pad 2 and the dust removal pad 4 are provided with a plurality of cylindrical holes corresponding to the positions of the through holes in the front cover 1. The intermediate base 3 is provided with a plurality of trapezoidal holes corresponding to the positions of the through holes in the front cover 1. The small-diameter end of the trapezoidal hole is in abutment with the cylindrical hole on the dust removal pad 4. The dustproof pad 2 is further provided with a dustproof cover 10. The cylindrical hole in the dust removal pad 4 is in interference fit with the pin. The dust removal pad is made of rubber. When the pin is inserted into the pin hole, the dust on the pin is removed by interference fit.

[0019] Further, one end of the cylindrical hole in the dustproof pad 2 is further provided with a circular ring table extending into the through hole in the front cover 1. The outer wall of the circular ring table is in abutment with the inner wall of the through hole in the front cover 1. The dustproof pad is made of soft rubber. The circular ring table extending into the front cover can prevent the pin from contacting the hard front cover, which causes wear of the pin and the front cover.

[0020] Further, the dustproof cover 10 is a flexible disc. A plurality of cuts are formed on the disc from the center to the radial direction. During the insertion of the pin, the cuts are inwardly recessed and broken under the action of the pin to form a channel for the pin to enter. When idle, the cuts are closed to prevent dust from entering the connector.

[0021] Further, the through holes in the upper base 5 and the lower base 6 are respectively machined into stepped holes at opposite ends. The support spring ring 9 is installed in the stepped hole on the upper base 5. The other end of the support spring ring 9 extends out of the upper base 5 and is placed in the stepped hole in the lower base 6. During installation, the lower base 6 fixes the support spring ring in the upper base.

[0022] Further, the support spring ring 9 is a cylinder. A plurality of elastic pieces are arranged on the inner wall of the support spring ring 9. One end of the elastic piece is connected to the support spring ring 9 adjacent to the lower base 6. The other end of the elastic piece is inclined along the center of the support spring ring 9. The elastic piece in the support spring ring serves as a component for contacting the pin in the pin hole. When the elastic piece contacts the pin, it is separated and presses the pin. The pin hole is in close contact with the pin.

[0023] Further, the end of the through hole in the sealing wire body 7 is machined into a step with a decreasing diameter from inside to outside. The middle part of the sealing sleeve 8 is machined into a circular ring groove. The width of the circular ring groove is the same as the width of the outermost through hole of the sealing wire body 7. The sealing wire body serves as a component for fixing the lead wire after the lead wire is connected to the connector. The sealing sleeve is used to cover the lead wire at the opening of the pin hole where the sealing wire body is inserted into the lead wire, thereby achieving the sealing effect of the other end of the connector.
