Abstract

The utility model relates to a miniature swift lock and separating electric connector, which comprises a socket and a plug and is characterized in that the electric connector is arranged at the plug with a lock and separate device which can realize instant locking and separating function, wherein the lock and separate device comprises a sheath, a sheath spring, a pulling rod, a steel ball, a socket and a locking spring, the locking spring is sleeved on the back of the pulling rod and positioned at the socket central hole together with the pulling rod, the socket is arranged at the part near the plug end with a hollow groove in radial direction, the hollow groove is provided with the steel ball, the protecting spring and the protecting shaft are positioned out of the socket and in the plug socket in axial direction. The utility model cancels special separating device and combines the lock device and separating device, which is compact, of small space, reliable in working and capable of separating swiftly.

Description

Miniature quick locking and separation connector

One, technical field

The utility model belongs to technical field of electric connectors.

Two, background technology

Snatch-disconnect connector belongs to extraordinary electric connector category, is made up of plug and socket, and comprises retaining mechanism, separating mechanism and the alarm mechanism etc. that skids.Retaining mechanism is realized the reliable locking of electric connector; Separating mechanism then separates required power for electric connector provides, and after the retaining mechanism release, finishes the automatic separation of electric connector; The alarm mechanism that skids then protects plug and socket not to produce excessive plugging together.General snatch-disconnect connector causes volume big owing to comprise various mechanism, and weight can't alleviate.Along with electric equipment products develop to high density, miniaturization, lightness direction, press for the miniaturization and the lightness that realize snatch-disconnect connector.

Three, summary of the invention

The purpose of this utility model is primarily aimed at present snatch-disconnect connector and has the problem that volume is big and weight can't alleviate, and a kind of miniature quick locking and separation connector are provided, and realizes the miniaturization and the lightness of snatch-disconnect connector.

Miniature quick locking of the utility model and separation connector comprise plug and socket, this socket is identical with socket in the common separation connector, lock sub-agencies with locking and separation function is set in plug, described lock sub-agencies is made up of sheath, sheath spring, pull bar, steel ball, lining, locking spring, step and chamfering are set on the pull bar, and locking spring is placed in pull bar step rear end and together places in the centre bore of lining with pull bar; Described lining radially is provided with groove near the place, mating side, places described steel ball in the groove; Sheath spring and sheath axial device before electric connector plugs together, under the effect of sheath spring, are pushed down steel ball by sheath outside lining, in the plug axle sleeve.

Adopt the advantage of the miniature snatch-disconnect connector of the utility model of said structure to be: to cancel the special separating mechanism of electric connector, retaining mechanism and separating mechanism are united two into one, utilized the sheath spring of retaining mechanism that separating force is provided.Has compact conformation, little, the reliable operation of taking up room, characteristics such as separation fast.

Four, description of drawings

Fig. 1 is a principal section view before the utility model plug plugs together;

Fig. 2 is plug of the present utility model and the socket principal section view when plugging together.

Among the figure: 1-sheath, 2-pull bar, 3-steel ball, 4-housing, 5-insulator, 6-jack, 7-lining, 8-sheath spring, 9-locking spring, 10-socket lock sleeve, 11-plug axle sleeve.

Five, embodiment

Below in conjunction with accompanying drawing embodiment miniature snatch-disconnect connector of the present utility model is described in further detail:

Miniature locking of the present utility model and separation connector are made up of plug and socket, and socket is identical with the socket of common separation electric connector, only simplify on plug and improve.This plug is made up of lock sub-agencies, housing 4, insulator 5, jack 6, plug axle sleeve 11 etc., the lock sub-agencies is made up of sheath 1, sheath spring 8, pull bar 2, steel ball 3, lining 7, locking spring 9, pull bar 2 is provided with step and chamfering, locking spring 9 is placed in pull bar 2 step rear ends and together places in the centre bore of lining 7 with pull bar, lining 7 radially is provided with groove near the place, mating side, place described steel ball 3 in the groove, sheath spring 8 and sheath 1 are contained in axially that lining is 7 outer, in the plug axle sleeve 11.

Before plug and socket plugged together, as shown in Figure 1, sheath spring 8 promoted sheath 1 retaining mechanism is remained on released state, and this moment, locking spring 9 was compressed, before sheath 1 is pressed in the pull bar chamfering fully with steel ball, in lining 7 grooves.

When plug and socket plug together, as shown in Figure 2, under the socket effect, move compression sheath spring 8 behind the sheath 1, when the steel ball 3 in lining 7 grooves is in the groove of socket lock sleeve 10, locking spring 9 just pushing drawing rod 2 reach ejects steel ball 3, and the steel ball 3 that ejects is stuck in the groove of socket lock sleeve 10, makes the retaining mechanism locking of locking.Behind the spring force of releasing force greater than locking spring 9, retaining mechanism could release.After the release, 1 reach of sheath spring 8 promotion sheaths will be locked sub-agencies again and be remained on released state, for the locking of next circulation is got ready.And after the release, sheath spring 8 promotes sheath 1 reach, promotes plug when just can use sheath 1 reach and realizes separating fast with socket, and this moment, the spring force of sheath spring 8 only needed to get final product greater than total separating force of connector.

Claims
