Problems solved by technology

From the above analysis, it can be seen that when the mechanical connection structure realizes the anti-pull and waterproof sealing effect of the electrical connector, it is necessary to tighten the two parts of the middle fastener and the nut respectively, which increases the number of parts on the one hand and makes the electrical connector accessories The structure is complex and the cost increases. On the other hand, it needs to be tightened twice when used, and the installation process is cumbersome.

Embodiment Construction

[0028] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Specific embodiments of the electrical connector accessories of the present invention, such as Figure 2 to Figure 5 As shown, the electrical connector accessory includes a sleeve 21 extending in the front-rear direction. The inner cavity at the rear end of the sleeve 21 guides and moves and is equipped with a compression ring 22. In this embodiment, the pressing piece is the pressing ring 23 , of course, the pressing piece can also be a spaced split pressing piece. The sealing ring 24 is arranged between the pressing ring 23 and the pressing ring 25 . During use, tighten the nut 26, and when the nut 26 moves forward, push the extrusion ring 25 to move forward and apply an extrusion force to the seal ring 24 to deform it to realize sealing, and the top pressure ring 23 transmits the extrusion force to the On the compression ring 22, the compress...

Abstract

The invention provides an electric connector accessory and an electric connector employing the same. A compression ring, a seal ring and an extrusion part of the electric connector accessory are sequentially assembled in an inner cavity in the rear end of a sleeve in a sliding manner; when a nut is screwed on the rear end of the sleeve, the nut moves forwards and drives the extrusion part to move forwards to exert extrusion force to the seal ring; the seal ring is extruded to deform and deforms along the radial direction; and the inner peripheral surface of the deformed seal ring is clung to a cable and the outer peripheral surface is clung to the sleeve to play a sealing role. Meanwhile, the extrusion force is transferred to the compression ring through the seal ring; and the compression ring shrinks along the radial direction and clamps the cable under the action of a throat structure on the inner wall of the sleeve. Thus, sealing and clamping of the cable can be simultaneously finished as long as the nut is tightened; the installation process is simplified; the number of parts is reduced; meanwhile, the electric connector accessory is simple in structure; and the cost is reduced.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an electrical connector accessory and an electrical connector. Background technique [0002] During the use of the electrical connector, it is often necessary to protect the electrical connector through electrical connector accessories to meet the waterproof and tensile requirements of the electrical connector. Common electrical connector accessories such as figure 1 As shown, it includes a straight sleeve 11, the front end of the straight sleeve 11 is used to connect the electrical connector, the cable 16 enters the inner cavity of the electrical connector accessory from the opening on the nut 15, and the inner cavity of the rear end of the sleeve 11 is sleeved There is a compression ring 13, and a rubber ring 14 is set inside the compression ring 13. The O-ring 12 is installed between the straight sleeve 11 and the compression ring 13 to realize the sealing between the two...
