Description

Technical Field

[0001] The utility model relates to the technical field of shielded connectors, in particular to a quick-insertion shielded connector with a multiple sealing structure. Background Art

[0002] Connectors are roughly divided into three types according to materials: metal type, plastic type, and metal-plastic hybrid type. The functionality of connectors is similar to that of cable shielding connectors, and they need to achieve the effects of sealing, fixing, and shielding. The structure of the connector basically includes four parts, consisting of a connector body, a fixing mechanism, a sealing mechanism, and a shielding mechanism. The connector body is installed at the insertion hole; the fixing mechanism prevents the cable and hose from relative movement in the axial and radial directions, and has a certain fixed pull-out resistance; the sealing mechanism completely seals the hose or cable from the insertion hole, so that the working space of the equipment can be isolated from the external environment, achieving waterproof and dustproof protection; the shielding mechanism conducts the cable shielding layer with the outer shell, so that the electromagnetic field generated when the high-voltage current passes through is completely shielded, preventing the strong electromagnetic field from damaging the internal components;

[0003] One end of the existing shielded connector requires the cable to be inserted so that the shielding layer of the cable is in full contact with the shielding ring to achieve conductive shielding. The cable sheath also needs to be fixed and sealed. Existing shielded connectors directly insert the cable, and it is impossible to determine whether the shielding layer on the cable extends into the shielding ring in the connector, which is very inconvenient. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a quick-plug shielded connector with a multiple sealing structure, which can first extend the cable into the interior of the connector so that the cable is fully in contact with the hose sealing ring in the connector to achieve retention and sealing, and leave sufficient length for the cable head to facilitate the installation of the connector on the housing, ensuring that the shielding layer on the cable can be in full contact with the triangular shielding ring to achieve a shielding effect.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a quick-plug shielded connector with a multiple sealing structure, comprising a shell, a connector connected to one side of the shell, a triangular shielding ring is provided inside the side of the shell away from the connector, a cylindrical shielding ring is provided on the outside of the shell away from the connector, the connector extends into the inner side of the shell, a fixing block is connected between the connector and the shell, and a hose sealing ring is fixed to the inner side of the connector.

[0006] As a preferred technical solution of the utility model, a plurality of fixing holes are provided on the inner side of one end of the shell connected to the connector, a plurality of fixing blocks are installed on the connector corresponding to the fixing holes, the fixing blocks extend into at least one group of the fixing holes, and the fixing holes penetrate the wall surface of the shell.

[0007] As a preferred technical solution of the utility model, an installation cavity is opened on the outside of the connecting head close to the side of the shell, and a spring is fixedly installed inside the installation cavity. One end of the spring is fixedly connected to the inner wall of the installation cavity, and the other end of the spring is fixedly connected to the fixed block.

[0008] As a preferred technical solution of the utility model, a slide groove is provided on the inner wall of the shell near the connector, one end of the slide groove is connected to the inside of the fixing hole, and the other side of the slide groove is connected to the outside of the end of the shell.

[0009] As a preferred technical solution of the utility model, a sealing ring is provided on the outside of one end of the shell away from the connector, and the sealing ring is located on one side of the cylindrical shielding ring outside the shell.

[0010] As a preferred technical solution of the utility model, a first mounting groove and a second mounting groove are provided on the outer side of one end of the shell away from the connector, and the cylindrical shielding ring and the sealing ring are respectively located inside the first mounting groove and the second mounting groove.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] The utility model can firstly extend the cable into the interior of the connector, so that the cable is fully in contact with the hose sealing ring in the connector to achieve retention and sealing, and leave sufficient length for the cable head to facilitate installation of the connector on the shell, ensuring that the shielding layer on the cable can be fully in contact with the triangular shielding ring to achieve a shielding effect.
