Abstract

The utility model discloses an electric connector having a spring dustproof cover, which is mainly composed of socket with jacks and jack welding ends and a plug with contact pins and contact pin welding ends. The utility model is characterized in that the socket is fixed with a spring dustproof cover which is matched with the jack welding ends. The utility model has the advantages of artful design and reasonable structure; when the plug is drawn out, the dustproof cover can be automatically closed under the action of the spring and has a dustproof and a splash proof functions, and thereby, the disconnection or short circuit phenomena can be thoroughly stopped.

Description

Electric connector

The utility model relates to a kind of interface unit, particularly relates to a kind of electric connector on the various mechanical control equipments that is used for that has the spring dust cap.

Existing at present, be used for the electric connector on the various mechanical control equipments, there is not the spring dust cap mostly.Service time one is long, suffers dust stratification, or meets when dabbling, the phenomenon that can produce short circuit or open circuit, thus cause the damage of control appliance.

The purpose of this utility model provides a kind of, can effectively overcome above-mentioned defective, has the electric connector of spring dust cap.

The technical solution of the utility model is, a kind of electric connector, mainly is made up of socket that has jack and jack welding ends and the plug that has contact pin and a contact pin welding ends, its characteristics are: be fixed with a spring dust cap that mates with the jack weld port on the socket.

Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is skillfully constructed, and is rational in infrastructure, when pulling the plug out of the socket, dust cap cuts out under the effect of spring automatically, plays dustproof, the anti-effect that dabbles, thereby thoroughly stop to open circuit or the generation of short circuit phenomenon the tool promotional value.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a cross-sectional view of the present utility model.

Fig. 2 is the side structure schematic diagram of the utility model socket.

Among the figure, the utility model is made up of socket 10 and plug 20.Socket 10 is the flange housing 16 of a hollow, is with rubber insulator 11 in it, is inserted with jack 12 in the rubber insulator 11, and left end is a jack weld part 121, and right-hand member is a hole portion 122.Plug 20 front ends are a sleeve pipe 25, also are with rubber insulator 21 in it, are inserted with contact pin 22 in the rubber insulator 21, and left end is a pin portion 221, and right-hand member is a contact pin weld part 222.Plug 20 tail ends are connected with a sealing ring 23.Axle 14 by being through at lug 17 on the socket 10 on the socket 10 and be placed in spring 13 on the axle 14, be fixed with one with the spring dust cap 15 of jack weld part port match.Wherein, spring dust cap 15 inner surfaces be provided with one with plug 20 on convex tendon 24 corresponding blocks 151.

During use, the jack weld part of socket is electrically connected with plant equipment, and the pin portion of plug inserts in the hole portion of socket, and the contact pin weld part of plug then links to each other with power line.When socket and plug joined, the block of spring dust cap just blocked convex tendon on the plug.Like this, the phenomenon of just having avoided plug to come off for no reason takes place.And when plug when socket pulls away, the spring dust cap then can tightly be placed on the jack weld port of socket under the effect of spring, plays dustproof, the anti-effect that dabbles, thereby thoroughly stops to open circuit or the generation of short circuit phenomenon.

Claims

1, a kind of electric connector mainly is made up of socket that has jack and jack welding ends and the plug that has contact pin and a contact pin welding ends, it is characterized in that: be fixed with a spring dust cap that mates with the jack weld port on the socket.
