The utility model provides a pair of threaded connector with locking structure that moves closes or separate the screw thread soon plug and socket, the adapter sleeve all can drive the stopping spring rotation of riveting above that, the salient point on the stopping spring can take place the friction and produce the hindrance moment with the ratchet on the housing part, it is just this hindrance moment to guarantee the connector vibration, under the impact condition, the screw thread is not hard up, do not influence the plug, the normal of socket is inserted and is closed, the contact to the screw thread is not hard up when guaranteeing connector normal use and drops.

Description

Threaded connector with anti-loosening structure

Technical Field

The utility model belongs to the technical field of the electronic connector among the electromechanical component, concretely relates to threaded connector with locking structure that moves.

Background

The connector is an electronic component with wide application, information transmission on and off is realized by inserting and separating the connector, when a plug end of the connector is inserted into a socket, connection and locking are usually needed to ensure that a connector plug and the socket are not separated under the action of external force so as to normally work, one connection and locking is realized by adopting threaded connection, and connection sleeve threads of the plug part are connected and locked with threads on the socket, but the problem of failure frequently occurs is that the connection threads are very easy to loosen under the condition of vibration or impact, so that the phenomenon of instantaneous disconnection occurs when the connector is contacted, and further the connector fails.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model discloses improve on this type of connector current, improve the structure of outside under the unchangeable prerequisite of line structure inside, concrete scheme is as follows:

the utility model provides a threaded connector with locking structure that moves, including plug and socket, plug and socket connection, wherein, the plug includes adapter sleeve and housing part, the adapter sleeve cover is established on the housing part, the inside of adapter sleeve sets up the stopping spring, the housing part with the position that the stopping spring is relative sets up the ratchet, set up the bump on the stopping spring, the bump embedding with in the tooth of ratchet.

Preferably, the retaining springs are in a V-shaped structure and are arranged into two groups, and the two groups of retaining springs are arranged one above the other and are fixed inside the connecting sleeve through rivets.

In any of the above solutions, preferably, the connection sleeve and the housing component are fixedly connected by a metal collar.

In any of the above schemes, preferably, the connecting sleeve is internally provided with plug threads, the socket is provided with socket threads, and the socket and the connecting sleeve are in threaded connection through the two thread structures.

The utility model has the advantages that: the utility model provides a pair of threaded connector with locking structure that moves closes or separate the screw thread soon plug and socket, the adapter sleeve all can drive the stopping spring rotation of riveting above that, the salient point on the stopping spring can take place the friction and produce the hindrance moment with the ratchet on the housing part, it is just this hindrance moment to guarantee the connector vibration, under the impact condition, the screw thread is not hard up, do not influence the plug, the normal of socket is inserted and is closed, the contact to the screw thread is not hard up when guaranteeing connector normal use and drops.

Detailed Description

In order to further understand the present invention, the present invention will be described in detail with reference to the following embodiments.

As shown in fig. 1 to 5, the utility model provides a threaded connector with locking structure that moves, including plug 9 and socket 10, plug 9 and socket 10 are connected, wherein, plug 9 includes adapter sleeve 2 and housing part 5, adapter sleeve 2 cover is established on housing part 5, the inside of adapter sleeve 2 sets up stopping spring 3, the position that housing part 5 and stopping spring 3 are relative sets up ratchet 7, set up the bump on stopping spring 3, the bump embedding with in the tooth of ratchet 7, stopping spring 3 is the V font structure and sets up to two sets, two sets of stopping spring 3 sets up one on one and all fix through rivet 4 in the inside of adapter sleeve 2, adapter sleeve 2 and housing part 5 pass through metal rand 1 fixed connection, the inside of adapter sleeve 2 sets up plug screw thread 6, socket screw threads 8 are arranged on the socket 10, and the socket 10 and the connecting sleeve 2 are in threaded connection through the two thread structures.

The utility model discloses a functional principle does:

two groups of retaining springs 3 are riveted on a connecting sleeve 2 through rivets 4, then a shell component 5 is installed, then the connecting sleeve 2 and the shell component 5 are fixed through a metal clamping ring 1, when the shell component 5 is inserted into a connector socket 10, radial displacement and irrotation between the shell component 5 and the socket 10 are guaranteed through a positioning key, the connecting sleeve 2 is screwed, threads of the connecting sleeve are locked with the socket threads, at the moment, the connecting sleeve 2 can drive the retaining springs 3 riveted on the connecting sleeve to rotate no matter the threads are screwed or separated, protruding points on the retaining springs 3 can rub with ratchets 7 on the shell component 5 to generate blocking torque, and the blocking torque guarantees that the threads are not loosened under the conditions of vibration and impact of the connector, and normal insertion and contact of the plug and the socket are not influenced.
