Abstract

The utility model provides a ball type quick push-pull locking and unlocking electric connector which is composed of a plug part and a socket part. Based on the conventional electric connector structure, a spring is arranged between an outer sleeve of a plug part and a plug shell, grooves are respectively arranged at the front edge butt joint end of the plug shell and the butt joint end of a socket shell, and balls are arranged in the grooves on the plug shell. In operation, the outer sleeve of the plug portion is pushed to compress the spring and the balls move in the radial direction of the plug housing. When the ball is jammed into the groove on the socket housing, the ball cannot move in the radial direction of the plug housing any more, thereby ensuring quick locking and separation of the electrical connector. The electric connector has the advantages of simple structure, durability, reliability, vibration resistance and impact resistance, and can realize the quick locking and separation of the plug and the socket part only by one push-pull action. The locking and separating device is convenient to operate, rapid in locking and separating and good in using effect.

Description

Quick Pushpulll locking of ball-type and release electric connector

Technical field

The utility model belongs to technical field of electric connectors.

Background technology

Normally used electrical connector latch system's employing screw thread or bayonet coupling structure, the screw-threaded coupling structure is that pin thread and negative thread are set respectively on the shell of plug and socket, utilizes the locking that realizes plug and socket that screws of screw thread; The bayonet coupling structure is the safetied pin that 3 protrusions are set on plug body, and 3 spill helicla flutes are set on jack housing, utilizes safetied pin to screw in helicla flute, realizes the locking of plug and socket.The device of these two kinds of locking mechanisms is in locking and all once or repeatedly screw action during release, causes the locking of plug and socket and release comparatively to bother, thus the quick locking that is unfavorable for plug and socket with separate.

Summary of the invention

The purpose of this utility model is the problem that exists at the structure of above-mentioned electrical connector latch to provide a kind of easy to operate, locks and separates rapidly quick Pushpulll locking of the ball-type that result of use is good and release electric connector.

Electric connector of the present utility model partly is made of plug and socket.Plug portion is made up of overcoat, plug body, plug circle packing, contact pin, sealing ring, stopper ring, ball, spring, Plug base, plug collar, plug supporting pad, wire clamp, swivel nut.Socket part is made up of jack housing, socket collar, jack, socket circle packing, socket supporting pad, socket base.

Contact pin of the present utility model is anchored in the plug body via plug circle packing, Plug base, plug collar, plug supporting pad.The tail end of plug body is provided with sealing ring, wire clamp, swivel nut successively.The overcoat front end is provided with stopper ring.Jack is anchored in the jack housing via socket circle packing, socket supporting pad, socket base.Be provided with the socket collar between socket supporting pad and the socket base.

Be provided with spring between overcoat of the present utility model and the plug body, the butt end in plug body forward position and the butt end of jack housing are respectively arranged with groove, are provided with ball in the groove on the plug body.

The plug of electric connector of the present utility model, socket part when not plugging together, the spring of plug portion and ball in the raw, ball can not move in the groove of plug body.When the plug tail end promoted, spring was compressed with overcoat, and ball can the radial direction along plug body move in groove.After plug and socket partly docked, ball was absorbed in the groove of jack housing, and unclamp the overcoat of plug portion this moment, and under the effect of spring, the overcoat of plug portion is returned to reset condition again.Because the effect of ball, plug and socket partly realize locking.As again with the overcoat of plug portion when the plug body tail end promotes, spring is compressed again, the ball in the groove can partly separate plug and socket like a cork in the motion in the radial direction of plug body again.

Electric connector structure of the present utility model is simple, and is durable reliable, and antivibration, anti-impact only need locking that a push pull maneuver can realize plug and socket part and separate.It is easy to operate, locks and separates rapidly, and result of use is good.

Embodiment

Below in conjunction with above-mentioned accompanying drawing example electric connector of the present utility model is described in further detail.The example of the utility model electric connector comprises the plug and socket part.Plug portion is made up of overcoat 1, plug body 2, plug circle packing 3, contact pin 4, sealing ring 5, stopper ring 6, ball 7, spring 8, Plug base 9, plug collar 10, plug supporting pad 11, wire clamp 12, swivel nut 13.Socket part is made up of jack housing 14, socket collar 15, jack 16, socket circle packing 17, socket supporting pad 18, socket base 19.

The contact pin 4 of the plug portion of the utility model electric connector matches with the jack (16) of socket part, and its tail end is connected to external circuit through lead.Contact pin 4 is anchored in the plug body 2 via plug circle packing 3, Plug base 9, plug collar 10, plug supporting pad 11.The tail end of plug body 2 is provided with sealing ring 5, wire clamp 12, swivel nut 13 successively, swivel nut 13 and wire clamp 12 be threaded fixing.The front end of the overcoat 1 of plug portion is provided with stopper ring 6.Jack 16 is anchored in the jack housing 14 via socket circle packing 17, socket supporting pad 18, socket base 19.Be provided with socket collar 15 between socket supporting pad 18 and the socket base 19, socket collar 15 plays stationarity and the sealing effect that improves socket.Be provided with spring 8 between overcoat 1 and the plug body 2, the butt end, forward position of plug body 2 and the butt end of jack housing 14 are respectively arranged with groove, be provided with ball 7 in the groove on the plug body 2, the groove that the butt end of jack housing 14 is provided with is used to hold the ball 7 on the plug body 2.

Before plug of the present utility model and socket part do not plug together, spring 8 in the raw, ball 7 can not move in the groove of plug body 2.When the plug tail end promoted, spring 8 was compressed with overcoat 1, and ball 7 can move along the radial direction of plug body 2 in groove.Plug is with after socket part docks, and ball 7 is in the radial direction motion of the effect lower edge of jack housing 14 plug body 2, and when ball 7 was stuck in groove on the jack housing 14, motion stopped, and plugs together the purpose that puts in place thereby reach electric connector of the present utility model.Want locking electric connector during operation, only need compress a lower spring 8, under the effect of ball 7, can realize fast plugging together.Once more when the plug tail end promotes, spring 8 is compressed again with overcoat 1, and ball 7 just can move along the radial direction of plug body 2 in groove again, reaches the plug and socket part is separated purpose smoothly.To remove locking during operation, only need compress a lower spring 8, under the effect of ball 7, can realize fast separating.
