Abstract

The utility model relates to a self-locking plug-pull type electronic connector and a plug thereof. The plug comprises a tube body one end of which is provided with a step tube surface and a step-shaped lock sleeve sheathed on the step tube surface of the tube body; the lock sleeve comprises a basic bushing section and an elastic claw bushing section which is arranged at one end of the basic bushing section with an inner diameter smaller than that of the basic bushing section; the elastic claw bushing section is provided with radial salients on the outer surfaces at the finger tips of each clavus; an anti-falling location sleeve is fixedly arranged on the tube body at the outer side of the elastic claw bushing section of the lock sleeve; the elastic claw bushing section of the lock sleeve is inosculated and matched with the tube body; the adducted annular clearances of the finger tips are arranged at the finger tips of the elastic claw bushing section of the lock sleeve and between the part near the finger tips and the tube body. The structure shortens the length of the cantilever of the clavus of the lock sleeve, enhances the intensity thereof, not only ensures the clavus of the lock sleeve to have certain radial elasticity to realize the self-locking and plugging-pulling of the plug and socket, but also can reduce the shaking of a cable during the using process which causes the clavus to deform, thus leading the salients to accidently pull out from the groove of the socket which leads the connector to be accidently unlocked, and improves the reliability of electric connection.

Description

A kind of self-locking plug-type electrical connector plug and self-locking plug-type electric connector
Technical field
The utility model relates to a kind of plug-type electrical connector plug and plug-type electric connector.
Background technology
At present, a kind of self-locking plug-type electric connector is arranged, its structure as shown in Figure 1, this electric connector comprises the plug and socket 6 that can realize plugging cooperation, plug comprises that an end has the body 1 and the stairstepping lock tube that is set on the body ladder pipe face of ladder pipe face, this lock tube comprises basic casing section 2 and is located at basic casing section 2 one ends, internal diameter is less than the elastic claw casing section 7 of basic casing section, elastic claw casing section 7 is by the axial groove of offering at interval along the casing wall circumferencial direction casing wall to be divided into several calvus to form, the groove depth of axial groove from the outboard end of lock tube elastic claw casing section 7 near the interior step that extends to lock tube, the part of calvus root interconnection is coincide with body 1 and is cooperated, elastic claw casing section 7 is provided with between whole calvus part and body 1 in the finger tip of entire body and receives annular space 3, when radial load acts on the calvus, calvus just can produce accordingly and move radially, and calvus can reset again in resilience after radial load disappears.Elastic claw casing section 7 all has projection 4 radially on the outer surface of each calvus finger tip, corresponding fluted in the endoporus of socket 6, in the process of plug socket, projection 4 is subjected to the extruding of socket 6 and inwardly receives in the footpath earlier with calvus, plug is inserted into the just groove on the alignment socket of position back projection 4, projection resets and snaps in automatically in the groove, realizes auto-lock function.After lock tube is assembled on the body 1, on the body in lock tube elastic claw casing section 7 outsides, also need set firmly an anticreep positioning sleeve 5, on the end face of anticreep positioning sleeve 5 relative lock tubes a conical surface 8 is arranged, when the responsive to axial force that plug, socket are separated is on body 1 or on the socket 6, anticreep positioning sleeve 5 and lock tube will lean on tightlyer, the conical surface 8 of anticreep positioning sleeve is shored the lock tube calvus and is expanded outwardly, and it is more firm to force projection on the calvus and socket clamping to get, and prevents that plug, socket break away from; During release, axial outwards pulling lock tube, the projection on the lock tube calvus is subjected to the extruding of socket 6 deviates from from the socket groove, in receive and receive in the finger tip in the annular space 3, realize the separation of plug, socket.
The connector of said structure is because the calvus of its lock tube elastic claw casing section 7 is longer, and be provided with between whole calvus part and body 1 in the finger tip of entire body and receive annular space 3, only the root at calvus is provided with support, causes the calvus cantilever longer, the rigidity of calvus a little less than, be easy to generate elastic deformation; In the use, after cable is connected on the body, when pulling or rock cable, some slight radial loads all might be pushed calvus makes it produce deformation, cause calvus to receive in finger tip in the annular space 3 and move, the projection 4 on the calvus is deviate from the socket groove, causes the unexpected release of connector.
The utility model content
The purpose of this utility model provides a kind of after cable is connected on the plug body, pulls or plugs and sockets can unexpected release when rocking cable self-locking plug-type electrical connector plug.
Another purpose of the present utility model provides a kind of after cable is connected on the plug body, pulls or plugs and sockets can unexpected release when rocking cable self-locking plug-type electric connector.
For realizing above-mentioned first purpose, the utility model adopts following technical scheme: a kind of self-locking plug-type electrical connector plug, comprise that an end has the body and the stairstepping lock tube that is set on the body ladder pipe face of ladder pipe face, this lock tube comprises basic casing section and is located at basic casing section one end, internal diameter is less than the elastic claw casing section of basic casing section, the elastic claw casing section all has projection radially on the outer surface of each calvus finger tip, on the body in the lock tube elastic claw casing section outside, be installed with the anticreep positioning sleeve, lock tube elastic claw casing section and body coincide and cooperate, are provided with between the position of the finger tip of lock tube elastic claw casing section and close finger tip and body and receive annular space in the finger tip.
For realizing above-mentioned second purpose, the utility model adopts following technical scheme: a kind of self-locking plug-type electric connector, comprise the plug and socket that to realize plugging cooperation, plug comprises that an end has the body and the stairstepping lock tube that is set on the body ladder pipe face of ladder pipe face, this lock tube comprises basic casing section and is located at basic casing section one end, internal diameter is less than the elastic claw casing section of basic casing section, the elastic claw casing section all has projection radially on the outer surface of each calvus finger tip, this projection is at plug, after putting in place, the socket connection snaps in the groove of being located at the socket endoporus, on the body in the lock tube elastic claw casing section outside, be installed with the anticreep positioning sleeve, it is characterized in that lock tube elastic claw casing section and body coincide cooperates, is provided with between the position of the finger tip of lock tube elastic claw casing section and close finger tip and body and receives annular space in the finger tip.
The utility model only is provided with near the finger tip of its lock tube elastic claw casing section and receives annular space in the finger tip, and the remainder of lock tube elastic claw casing section is cooperated with body is identical, shortened the jib-length of lock tube calvus greatly, the rigidity of calvus is strengthened, can guarantee that like this lock tube calvus has certain radial elastic to realize plug after installation, the self-locking plug of socket, can in the connector use, reduce again to pull or rock the deformation that calvus is squeezed produce because of cable, prevent that lock tube projection accident from deviating from the socket groove and causing the unexpected release of connector, guaranteed the reliability that connector in use connects.
