Connector with locking in-place identification function

Abstract

The invention provides a connector with a locking in-place identification function. The connector comprises a locking screw sleeve, a plug and a socket, wherein the plug and the socket are butted with each other; and the locking screw sleeve comprises an inner screw sleeve and an outer screw sleeve, an axial elastic reset mechanism and a circumferential limiting mechanism are arranged on the matching surface of the outer screw sleeve and the inner screw sleeve, the circumferential limiting mechanism comprises a plurality of key groove structures which are in sliding fit in the axial direction, the key groove structures are arranged on the outer screw sleeve and the inner screw sleeve respectively, and when the screwing structure and the butt joint end are screwed in place, the key groove structures are staggered until only the end parts are engaged, continue to rotate in the screwing direction, and relatively rotate in the circumferential direction under the action of the end part guide structures and are periodically staggered and interfered. According to the connector with the locking in-place identification function, when butt joint and screwing are in place, the auditory sense and touch sense identification functions are achieved, blind insertion operation is more convenient and reliable, meanwhile, it is guaranteed that the screwing torque is proper, the connection reliability is improved, and the mechanical life of the locking threaded sleeve is prolonged.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a connector with a locking in place identification function. Background technique [0002] With the integrated development of system equipment, its volume is getting smaller and smaller, and the internal space is reduced accordingly, and then the line of sight is blocked. As a key component in the system, the installation and docking operations of electrical connectors are thus more difficult. However, most of the commonly used threaded connectors can only be judged by the human eye to observe the marks on the connector. Once the line of sight is blocked, it will not be possible to judge whether the connector is connected in place, and the role of the screw sleeve is mainly used for loosening. For example, the Chinese patent with the publication number CN211320503U provides a radio frequency coaxial connector with a screw sleeve locking and anti-vibration structur...

Problems solved by technology

However, most of the commonly used threaded connectors can only be judged by the human eye to observe the marks on the connector. Once the line of sight is blocked, it will not be possible to judge whether the connector is connected in place, and the function of the screw sleeve is mainly used for loosening. For example, the Chinese patent with the publication number CN211320503U provides a radio frequency coaxial connector with a screw sleeve locking and anti-vibration structure. The screw sleeve and the lock nut are locked positively and reversely. To prevent the threaded sleeve and the socket from falling off, in the state where visual observation is impossible, the screwing in place can only be done by hand feeling, which may easily cause the thread to be screwed too tightly and cause wear, resulting in serious consequences such as redundant objects
