Description

Shockproof suspension type connector

Technical Field

The utility model relates to a shockproof suspension type connector.

Background

At present, connectors are widely used in electric power systems and communication systems to realize electric power transmission, signal transmission and mechanical performance erection.

The loosening of the threaded sleeve of the connector in connection failure is a difficult problem in the industry all the time, and the traditional connector has no loosening and vibration resistance, so that the connector can be loosened after being used for a period of time, and particularly in a vibration environment such as a vehicle-mounted system, the performance transmission is affected, and a certain accident can be caused.

Particularly, as shown in fig. three, the conventional threaded connector generally uses a clamping ring to connect the connecting screw sleeve with the shell, and has the following defects that 1, the fixing is difficult, and the connecting screw sleeve is only provided with a fixing reticulation outside, so that the connecting screw sleeve cannot be further reinforced after being manually pre-tightened; 2. the shock resistance is poor, and after the connecting screw sleeve is used for connection, the pure thread connection can be loosened due to vibration after the connecting screw sleeve is subjected to vibration; 3. easily become flexible, after the connection, because long-time work, frictional force mechanical fatigue between screw thread and screw thread reduces rapidly, finally leads to becoming flexible.

Disclosure of Invention

The present utility model is directed to a vibration-proof suspension connector, which solves the above-mentioned problems in the prior art.

In order to solve the technical problems, the utility model provides the following technical scheme: the screw sleeve is characterized by comprising a shell, wherein a rotatable screw sleeve is arranged on the surface of the shell, an extrusion cavity capable of generating elasticity is formed between the screw sleeve and the shell, and a hexagonal block is arranged at the screwing end of the screw sleeve.

Preferably, the surface of the shell is provided with a protruding block, and an extrusion cavity is formed between the hexagonal block and the protruding block.

Preferably, the surface of the hexagonal block is provided with a rotating ring, and the threaded sleeve is arranged on the rotating ring.

Preferably, the compression cavity is internally filled with a compression spring.

Preferably, the blocking end of the shell is provided with a retainer ring.

Preferably, the surface of the rotating ring is hollow net-shaped.

Compared with the prior art, the utility model has the beneficial effects that:

when the screw sleeve is used, the shell and the screw sleeve are in a suspension state, so that the screw sleeve can move, the screw sleeve on the surface of the shell is inserted into another connector to be abutted, the screw sleeve is pushed forward, the screw sleeve is manually pre-tightened by friction force of reticulation, six blocks on the screw sleeve are tightly clamped by using a spanner, connection can be completed, the whole body is tightly fastened by means of the six blocks, threaded connection is tighter, in the fastening process, a compression spring can be extruded, threads are always in a larger pressure state under the action of the characteristic that the compression spring can continuously and stably provide elasticity for a long time, two threads are tightly attached, and accordingly the purposes of shock resistance and loose resistance are achieved.
