Abstract

The utility model relates to a waterproof electric connector used for power supply cable connection, comprising a socket and a plug, wherein the plug and the socket are respectively provided with a housing, an insulating member and an inner conductor, the rear end of the housing of the plug is provided with an insertion hole for cable extending thereinto, the rear end of the insertion hole is equipped with an axially-moving clamping sleeve, the rear of the clamping sleeve is propelled by a nut rotatably connected with the rear end of the housing of the plug, the front of the clamping sleeve is provided with a pressing ring, the pressing ring presses on an annular seal ring at the front thereof, and the front end of the annular seal ring is limited by steps at the middle segment of the insertion hole. The waterproof electric connector applies an axial pressure on the seal ring located inside the housing of the plug through the nut, the clamping sleeve and the pressing ring to enable the inner bore of the seal ring to deform and to clasp the rubber sheath of the cable, thereby ensuring reliable seal and satisfying the use conditions of ship waterproofing, is simple in structure and convenient in manufacturing and mounting, and enables the manufacturing process of sulfuration moulding seal in the traditional structure to be omitted.

Description

Waterproof electrical connector
Technical field
The utility model relates to a kind of waterproof electrical connector that feed cable connects that is used for.
Background technology
Common electric connector includes socket and plug, and plug and socket has shell, insulating part and inner wire separately respectively, and the plug rear end is provided with the patchhole that current supply cable stretches into.For the electric connector that is used for boats and ships; The coupling part of cable and plug body has higher waterproof requirement, adopts elastomeric material that the outer gum cover and the whole sulfuration of plug body of cable are combined as a whole usually, to satisfy waterproof requirement; But this manufacture complex process, manufacturing cost is high.
Summary of the invention
The utility model technical problem to be solved is, provides that a kind of manufacturing process is simple, easy for installation, the good waterproof electrical connector of waterproof sealing property of cable and plug coupling part.
The waterproof electrical connector of the utility model includes socket and plug; Plug and socket has shell, insulating part and inner wire separately respectively, and the plug body rear end is provided with the patchhole that current supply cable stretches into, and the patchhole rear end is equipped with one can axially movable cutting ferrule; The cutting ferrule rear is promoted by a nut that is screwed in the plug body rear end; Cutting ferrule the place ahead is provided with a pressure ring, and pressure ring is pressed in the O-ring seal in its place ahead, and the O-ring seal front end is spacing by the step that is positioned at the patchhole stage casing.
Said cutting ferrule back segment is distributed with a plurality of inside and outside slits that connect, and the cutting ferrule back segment is divided into a plurality of rubber-like claws, and the rear end face of cutting ferrule and the contact-making surface of above-mentioned nut are the conical surface simultaneously.
The front end face of said pressure ring is provided with the projection of annular.
The utility model applies axial compressive force through nut, cutting ferrule and pressure ring to the sealing ring that is positioned at plug body, makes ring inner hole be out of shape and hold tightly the rubber sheath of cable, has guaranteed positiver sealing, can satisfy the service condition of boats and ships waterproof.The manufacture process of sulfidization molding sealing in the traditional structure has been saved in its simple in structure, manufacturing and easy for installation simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in the figure; This waterproof electrical connector includes socket 1 and plug 2; Plug and socket has shell, insulating part and inner wire separately respectively, and plug body 11 rear ends are provided with the patchhole 12 that current supply cable stretches into, and the patchhole rear end is equipped with one can axially movable cutting ferrule 3; The cutting ferrule rear is promoted by a nut 4 that is screwed in plug body 11 rear ends; Cutting ferrule the place ahead is provided with a pressure ring 5, and pressure ring is pressed in the O-ring seal 6 in its place ahead, and the O-ring seal front end is spacing by the step that is positioned at the patchhole stage casing 13.When inwardly screwing nut 4, make cutting ferrule apply axial compressive force to sealing ring through pressure ring, force ring inner hole to internal strain, thereby closely hold tightly on the rubber sheath of cable, realize waterproof sealing.
Cutting ferrule 3 back segments are distributed with a plurality of inside and outside slits 31 that connect, and the cutting ferrule back segment is divided into a plurality of rubber-like claws 32, and the rear end face of cutting ferrule and the contact-making surface of above-mentioned nut are the conical surface simultaneously.When nut compressing cutting ferrule, can make claw inwardly compress cable, prevent to get loose, the elasticity of claw also makes cutting ferrule that pressure ring is had certain precompression simultaneously, to guarantee sealing effectiveness.
The front end face of said pressure ring 5 is provided with the projection 51 of annular, through the annular projection part sealing ring is oppressed, and can strengthen the effect of sealing ring deformable seal.
