Problems solved by technology

In the cooperation between the flange and the cabinet, it is usually necessary to add a sealing ring to play a sealing role between the connector base and the cabinet. There is no connecting flange on the connector base of the prior art, which makes it difficult to install the sealing ring. Some connector bases are equipped with flanges, and ring grooves with sealing rings are also set on the end faces of the flanges. Because the cross-section of the ring groove is a rectangular cross-section, and because the installation orientations of the connector base and the cabinet are different, when installing During the process, the sealing ring will fall off and shift, which will cause unnecessary troubles that the sealing ring will fall into the cabinet, or it will not be able to achieve the purpose of sealing the connector base and the cabinet.

Abstract

The invention discloses a flange connector with a dovetail groove structure, which comprises a connector base, a sealing gasket, an insulator, a contact member, a clamping nail and an O-shaped ring. The connector base is an assembly of a cylinder and a square flange, a sealing groove is arranged in the cylinder, and an annular groove with dovetail-shaped cross section is arranged on the end face of the square flange. The sealing gasket and the insulator are arranged in the cylinder, the contact member is arranged in the insulator, the clamping nail is arranged in a screw hole of the connector base, and the O-shaped ring is arranged in the annular groove of the square flange. One square flange is arranged on the connector base, the annular ring with the dovetail-shaped cross section is arranged on the end face of the square flange, the O-shaped ring cannot fall off by itself after being preassembled, and the O-shaped ring is pressed and deformed to complete sealing after the flange connector and a machine cabinet are installed.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a flanged connector with a dovetail groove structure. Background technique [0002] Flange connectors are mainly used in the connection between complete sets of electrical equipment and external cables. The connectors are fixed at the opening of the complete equipment cabinet through the flange, and then the cabinet and external cables are realized by cooperating with the cable assembly connected to it. Connection. In the cooperation between the flange and the cabinet, it is usually necessary to add a sealing ring to play a sealing role between the connector base and the cabinet. There is no connecting flange on the connector base of the prior art, which makes it difficult to install the sealing ring. Some connector bases are equipped with flanges, and ring grooves with sealing rings are also set on the end faces of the flanges. Because the cross-section of the rin...
