Connecting structure

Abstract

The invention provides a connecting structure which comprises a base, a sleeve and a cap, external threads are arranged on the surface of the base, an inner protruding key is arranged on the cap, the sleeve is provided with internal threads, an outer protruding key and a plurality of blind holes, and an elastic piece and an ejector head are correspondingly placed in each blind hole; when the base and the sleeve are in meshed connection through the external threads and the internal threads and the sleeve and the cover cap are in meshed connection through the outer protruding key and the inner protruding key, the elastic pieces drive the ejectors to abut against the inner wall of the cover cap through the elastic force of the elastic pieces. By the adoption of the technical scheme, the connection structure is tighter and more reliable through the meshing dual-matching structure of a thread pair, the outer protruding key and the inner protruding key, an operator can conveniently identify whether the connection structure is firmly and reliably assembled or not during assembly, breakage caused by overexertion of the operator can be avoided, the situation that the connecting structure is not assembled firmly and reliably due to the fact that an operator exerts too light force is avoided, the axial preload is increased in the connecting structure through the corrugated blocking piece, and the connecting reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a connection structure. Background technique [0002] There are a large number of connection structures in various existing industrial products and daily necessities. These connection structures are used to make the corresponding parts fixedly connected together. Among them, threaded connection is the most common connection method, and the electrical connector with threaded connection is used. It is to connect the corresponding plug and socket together through the thread pair. However, due to the inevitable errors in the production and processing of the parts, the corresponding thread structure on the parts also has errors. When the corresponding parts are connected through the thread pair, The matching structure of the thread pair will also produce corresponding errors, which will affect the sealing performance of the connector, and when the connector is subjected to external...

[0002] There are a large number of connection structures in various existing industrial products and daily necessities. These connection structures are used to make the corresponding parts fixedly connected together. Among them, threaded connection is the most common connection method, and the electrical connector with threaded connection is used. It is to connect the corresponding plug and socket together through the thread pair. However, due to the inevitable errors in the production and processing of the parts, the corresponding thread structure on the parts also has errors. When the corresponding parts are connected through the thread pair, The matching structure of the thread pair will also produce corresponding errors, which will affect the sealing performance of the connector, and when the connector is subjected to external force, the screw teeth will often slip only by relying on a single thread pair connection structure, which further affects the sealing of the connector In addition, when people operate the plug and socket to make them fixedly connected together, the operator often operates only by subjective feeling. If the operator uses too much force, the thread pair will break. If the operator uses too little force, the connection structure will not be tight and reliable, which will affect the overall performance of the connector.
