Technical Field

The invention relates to the technical field of cable connection equipment, in particular to a spiral locking device suitable for an electric plug connector and a female socket of the electric plug connector.

Background

The electrical plug connection, in which the two parts of the electrical plug connector and the female socket of the electrical plug connector interact with each other to effect a connection, can be used for connecting an electrical cable to an electrical or electronic device and also for connecting two electrical cables to each other. When connecting an electrical cable to an electrical plug connector or to a female electrical plug connector receptacle, it is customary to provide an external threaded connection on the electrical plug connector or the female electrical plug connector receptacle and then to screw-lock the cable-securing device onto the external threaded connection. However, the existing connecting structure is complex, the thread fastening time is long, the construction efficiency is low, and the installation or the disassembly of the thread clamping device is complex, so that the labor cost is increased easily.

Disclosure of Invention

In order to overcome the above disadvantages, the present invention provides a screw locking device suitable for an electrical plug connector and a female socket of the electrical plug connector, which realizes the quick assembly and disassembly of cable connection, solves the problems of complex installation and long time consumption of a screw fastening structure, and greatly saves the installation cost.

In order to achieve the above purposes, the invention adopts the technical scheme that: a spiral locking device comprises a spiral body and a spiral fixing cap, wherein the spiral body is fixedly arranged on an electric plug connector or a female socket of the electric plug connector, and a buckling groove is formed in the spiral body. The spiral fixing cap can be inserted into the spiral body in a rotating mode, and a locking portion which can be locked into the locking groove is arranged on the spiral fixing cap. The buckling groove comprises a strip-shaped groove body which is obliquely arranged along the side wall of the spiral body, one end of the strip-shaped groove body is provided with a groove body opening which is arranged along the edge of the spiral body, and the other end of the strip-shaped groove body is provided with a locking structure which is used for locking the locking part.

The invention has the beneficial effects that: during installation, the spiral fixing cap is inserted into the spiral body in a rotating mode, the quick assembly and disassembly of the spiral fixing cap and the spiral body are achieved through the arrangement of the lock catch portion and the buckling groove, the problems that in the prior art, a thread fastening structure is complex to install and long in time are solved, and installation cost is greatly saved.

Further, the locking structure comprises a rotary groove communicated with the strip-shaped groove body, and a clamping point protrusion used for clamping the lock catch part is arranged at the joint of the rotary groove and the strip-shaped groove body. The lock catch part can be locked in the rotary groove through the function of the clamp point protrusion.

Further, a slope-shaped holding surface capable of abutting against the locking portion is provided in the rotary groove. The lower point of the slope-shaped holding surface is positioned at the joint of the rotary groove and the strip-shaped groove body, and the higher point of the slope-shaped holding surface is positioned in the rotary groove. Make hasp portion present the state that compresses tightly gradually (hasp portion and domatic holding surface's clearance reduces gradually) when entering into the rotary tank through the setting of slope form holding surface low point and high point position, present the state of loosening gradually when leaving the rotary tank (hasp portion and the clearance crescent of slope form holding surface), and then make hasp portion lock fasten more when the rotary tank, and light when unbuckling.

Further, the spiral fixing cap is of a hollow shell structure, one end of the spiral fixing cap is a wire inlet, and the other end of the spiral fixing cap is a wire outlet. One end of the outlet is provided with the locking part.

Further, a contracting arc surface which gradually and radially contracts from the direction far away from the wire inlet to the direction close to the wire inlet is arranged on the inner wall of one end, close to the wire inlet, of the spiral fixing cap. The arrangement of the contraction arc surface is convenient for being matched with a wire bundling mechanism to clamp the cable.

Further, the spiral fixing cap is close to one end inner wall of the wire outlet, a guide yielding inclined plane is arranged on the inner wall of the end of the wire outlet, and a wire inlet guide inclined plane matched with the guide yielding inclined plane is arranged on the outer wall of the spiral body. The arrangement of the guide abdicating inclined plane and the inlet wire guide inclined plane enables the plug connection between the spiral fixing cap and the spiral body to be smoother.

Furthermore, a plurality of anti-skid grooves which are convenient for the spiral fixing cap to be plugged into the spiral body in a rotating manner are uniformly distributed on the outer wall of the spiral fixing cap. The arrangement of the anti-slip groove can facilitate force application of workers to rotate the spiral fixing cap, and the phenomenon of slipping during rotation is prevented.

Further, still detachably nestification has the bunch mechanism on the spiral locking cap, the bunch mechanism includes the annular collet, one side of annular collet is equipped with a plurality of bunch posts that are circumference array and distribute, and is a plurality of the inside of bunch post forms the bunch space that is used for the holding cable jointly, the inboard of bunch post still is equipped with the bunch back-off.

Further, be equipped with the breach of stepping down on the outer wall of annular collet, the outside of restraint line post is equipped with the confession the spout that the hasp portion removed, at least one the spout with the breach of stepping down communicates. The arrangement of the abdicating notch and the sliding groove can abdicate for the lock catch part when being embedded into the wire bundling mechanism.
