Abstract
The utility model relates to a connector with a threaded anti-loosing structure, which comprises a casing, wherein a contact element is arranged in an inner hole of the casing and is fixed in the inner hole of the casing through an insulation body, connecting screw caps with connection screw threads at the front section of the inner hole are arranged at the front part and the back part of the front section of the outer peripheral surface of the casing in an anti-loosing way, and fixed tensioning wire passing holes with two end openings respectively positioned on the outer periphery surface of the connecting screw caps are arranged on the connecting screw caps. The fixed tensioning wire passing holes are arranged on the connecting screw caps, after the connector is inserted with a matched connector and is tightly locked through the connecting screw caps, fixed tensioning wires pass through the fixed tensioning wire passing holes and are fixed onto a connector installation panel, so the connecting screw caps can be tightly tensioned by the fixed tensioning wires, the connecting screw caps can not freely rotate relative to the connector, the screw thread looseness between the connecting screw caps and the matched connector is prevented, and the reliable insertion between the connector and the matched connector is ensured.
Description
Technical field
The utility model relates to a kind of connector that is used for delivered current or signal with locking thread structure.
Background technology
Need a large amount of connector transmission signals or transmission current at electric field, connector comprises the plug and socket that plugs together mutually, in use, plug and socket plugged together gets final product.In actual use, sometimes plug and socket can be operated in the environment with vibration, at this moment only depend on the tight fit between the plug and socket just can't meet the demands, plug and socket can be separated from each other in vibration, in order to make plug and socket reliably to plug together, can use coupling nut that plug and socket is locked in the prior art, can be with before the coupling nut, back anticreep is arranged on the front end of plug, that is to say, coupling nut can rotate with respect to plug but can not take off, the structure that realizes this function is a lot, such as, step surface towards the rear end is set on the housing of plug, and this step surface cooperates along block with the retaining of coupling nut tail end setting, and plug with or the jump ring that cooperates with the rear end block of coupling nut of the outer peripheral face setting of socket.The screw thread of the endoporus front end of coupling nut cooperates with screw-threaded coupling on the socket front end outer peripheral face in use, guarantees that plug and socket reliably plugs together.But in vibration environment, screw thread can produce loosening, causes separating of plug and socket.
The utility model content
The purpose of this utility model is to provide a kind of connector with locking thread structure, when guaranteeing that to solve the available technology adopting coupling nut plug and socket reliably plugs together, can produce the problem of thread looseness.
For achieving the above object, the utility model adopts following technical scheme: a kind of connector with locking thread structure, comprise housing, be provided with contact in the endoporus of housing, contact is fixed in the endoporus of housing by insulator, the forward and backward anticreep of the leading portion of housing outer peripheral face is provided with the coupling nut that the endoporus leading portion has connecting thread, has two ports on the described coupling nut and all is positioned at fixed strain silk perforating on the outer peripheral face of coupling nut.
The outer peripheral face of described coupling nut is a prismatic surface, and two ports of described fixed strain silk perforating lay respectively on two adjacent planes of outer peripheral face of coupling nut.
Described fixed strain silk perforating is a straight hole.
Described fixed strain silk perforating is three.
Described insulator is a ceramics insulator.
The step surface roof pressure of the setting in the rear end of described insulator and the housing endoporus cooperates, and the front end of insulator cooperates with the throat structure roof pressure of housing front end.
Coupling nut of the present utility model is provided with fixed strain silk perforating, when connector and intermateable connector plugs together and by after the coupling nut locking, with the fixed strain silk by passing in the fixed strain silk perforating and the fixed strain silk being fixed on the connector installation panel, like this, the fixed strain silk will be strained coupling nut, make coupling nut arbitrarily not rotate relative to connector, prevent the thread looseness between coupling nut and the intermateable connector, guarantee that connector and intermateable connector reliably plug together.
The outer peripheral face of coupling nut of the present utility model is a prismatic surface, and two ports of fixed strain silk perforating lay respectively on two adjacent planes of outer peripheral face of coupling nut and are straight hole, fixed strain silk perforating easy to process, good manufacturability.
Insulator of the present utility model is a ceramics insulator, and the resistance to elevated temperatures of ceramics insulator is good, and connector can be worked in high temperature, hyperbaric environment for a long time.
