Embodiment Construction

[0019] Embodiment 1 of the anti-thread backward connector of the present invention, such as Figure 1-9 As shown, it includes an inner casing 1 and an outer casing 2. The outer casing 2 is coaxially sleeved outside the inner casing 1 and rotates with the inner casing 1. In addition, the front end of the outer casing 2 is provided for matching with the The external thread 2-1 of the connector 3 is threaded, and the inner housing 1 is provided with an anti-rotation structure for anti-rotation cooperation with the adapter 3. In this embodiment, the anti-rotation structure is provided at the front end of the inner housing 1 , specifically two guide columns 1-1 arranged on the front end surface of the inner casing 1, the two guide columns 1-1 are evenly distributed on the front end surface of the inner casing 1 around the centerline of the inner casing 1, and, The thickness of each guide column in the radial direction of the inner housing is greater than the thickness of the inner ...

Abstract

The invention relates to an anti-unscrewing connector, which comprises an inner shell and an outer shell, the outer shell is coaxially and rotatively sleeved on the inner shell, the inner shell is provided with an anti-rotation structure which can be fitted in an adapter and can prevent rotation, the front end of the outer shell is provided with a screw thread which can be screwed in the adapter, the periphery of the inner shell is provided with spring sheets, one end of each spring sheet is fixedly connected with the inner shell, the other end of each spring sheet is suspended and extended along the circumference of the inner shell and a rotational direction in which the outer shell is unscrewed from the adapter, one side of the suspended and extended end of each spring sheet, which is opposite from the inner shell, is provided with an anti-unscrewing tooth, the inner wall of the outer shell is provided with V-shaped sockets in which the anti-unscrewing teeth can be inserted, and the slope of one of the sidewalls of each V-shaped socket, which is located at the front in the rotational direction of screwing the outer shell, is steeper than the slope of the other sidewall of the V-shaped socket. The invention solves the problem that the conventional anti-unscrewing mechanism for connectors has a large number of parts and a complex structure.

Description

technical field [0001] The invention relates to electrical or optical connection accessories, in particular to an anti-screw reverse connector. Background technique [0002] Adaptive anti-backward mechanism is necessary for many thread connection scenarios, especially fast thread connection application scenarios such as three-head thread, because if the fast connection is not processed, the enlarged slope means fast and easy loosening Most of the threaded connectors include an inner shell and an outer shell that is coaxially rotatable and sleeved on the inner shell. The front end of the outer shell is provided with internal threads. The anti-rotation fit between the housing and the mating connector, and the threaded fit between the outer housing and the housing of the mating connector through the internal thread at the front end, so as to realize the reliable connection and locking between the corresponding two connectors, wherein In order to prevent the automatic loosening...
