The electric connector is characterized in that the electric connector can ensure reliable jointing and the stable and good performance of signal transmission, the cost of production is low, and rapid unlocking can be easily operated.

Description

Anti-misplug quick plug-in electric connector

One, technical field

The utility model belongs to technical field of electric connectors, relates in particular to anti-misplug quick plug-in electric connector.

Two, background technology

Tradition quick plug-in electric connector relies on binding ring to realize the quick connection of plug and socket.Realize the release of plug and socket, can add external force to separating lock tube, make it to axially move, binding ring comes off out from the groove on the socket surface.Binding ring will be locked by above-mentioned groove automatically when plug and socket plugged together.Said structure is undoubtedly a kind of good mode for single core product, but then is difficult to realize for high density multicore product.

Three, summary of the invention

The purpose of this utility model has provided a kind of new structure mode to realize anti-misplug quick plug-in electric connector.The utility model plug body and jack housing design have the location structure that cooperatively interacts, realize the mistake proofing plugging function, plug is equipped with the nonmetal stay pipe that inner chamber is taper simultaneously, stay pipe is that an inner chamber is taper, elasticity is non-metal workpiece preferably, inner chamber taper stay pipe because of the pressure that is subjected to vertical axial between plug and socket, formed circumference contact-making surface closely.Inner chamber taper stay pipe applies axially and the power of vertical axial plug, socket simultaneously, limit these two plaies after this connection tentaculum butt joint, the nonmetal support of inner chamber taper can make pressure continue to exist, thereby guarantees the reliability of butt joint, the stability and the good electric property of signal transmission.This connector production cost is low and have characteristics such as fast lock is easy to operate.

Five, embodiment

Anti-misplug quick plug-in electric connector of the present utility model, it by stay pipe 1, needle contact piece 2, insulator 3, shell 4, separate lock tube 5, binding ring 6, jack housing 7, hole contact 8, socket insulator 9 and form.Stay pipe 1, be arranged in the plug cavity, be provided with a plurality of needle contact pieces 2 in the plug body 4, it between the needle contact piece 2 insulator 3, be provided with at the skin of plug body 4 and separate lock tube 5, one end of its inherent stay pipe 1 is provided with binding ring 6, be provided with stay pipe in the inboard of binding ring 6 and separate lock tube mating surface 12, left end is provided with stay pipe and socket positioning groove mating surface 11, be provided with location notch 13 in lock sleeve 5 inboards, its inner face place also is provided with circular arc inner edge 14, is provided with positioning key 10 on shell 4, lock sleeve 5 is respectively equipped with positioning key 15 and location notch 16 and groove 18, socket and stay pipe mating surface 17 with the axial direction of jack housing 7.Blind positioning key 15 and location notch 16 engagements when slotting, plug and socket could correctly dock, realize anti-misplug, groove 18 engagements during locking on binding ring 6 and the socket, separate during release lock tube 5 by circular arc inner edge 14 axial force distributions in separating lock tube mating surface 12, radial dilatation take place in binding ring 6, make its binding ring 6 withdraw from groove 18 on the socket.

Separating lock tube 5 designs in the utility model has location structure location notch 13, shell 4 designs to have location structure positioning key 10, location notch 13 and positioning key 10 can realize shell 4, separate lock tube 5 position relative fixed.Simultaneously at the axial direction of separating lock tube 5 and jack housing 7 Design Orientation key 15 and location notch 16 respectively, blind have only positioning key 15 and location notch 16 smooth engagements just can finish the correct butt joint of plug and socket when slotting.Thereby realized the mistake proofing plugging function.Separate lock tube 5, binding ring 6, shell 7 is to realize that connector is locked fast and the critical component of release, realize the locking of plug and socket, only location structure positioning key 15, location notch 16 need be aimed at, plug and socket is applied axial force, and binding ring 6 can mesh and the butt joint of realization plug and socket with the groove 18 on the socket B.If want release, can push separating the direction of lock tube according to arrow A, be that direction from right to left among Fig. 3 pushes it, separate lock tube and force in 12 through circular arc inner edge 14, binding ring 6 produces radial dilatation, until breaking away from groove 18, so far binding ring 6 has withdrawed from groove 18, thereby finishes mandatory release.

For avoid butt joint back axially because tolerance is causing play, the utility model has designed nonmetal inner chamber taper stay pipe 1 and it is placed in the plug inner chamber and forms interference fit with the shell 7 of socket.So produce the pressure that axially reaches vertical axial, guaranteed the stability of butt joint.The interaction of inner chamber taper stay pipe 1 and jack housing.
