Description

Technical Field

[0001] The utility model belongs to the field of USB interface devices, and particularly relates to a USB female head connector with a bent angle protection. Background Art

[0002] The USB female head connector, as an electronic connector, is an important part of the USB interface system and is used to receive or accept the connection of the USB male head (i.e., the plug). In electronic devices or apparatuses, the USB female head connector usually consists of parts such as metal contacts, insulators, and shells. The metal contacts are used to contact the contacts of the USB male head to achieve the transmission of electrical signals and data. In the prior art, especially in those areas with a compact space or specific angle limitations in the design, the traditional straight USB female head connector cannot change the receiving angle, resulting in the problem of bending loss of the inserted receiving cable. Summary of the Utility Model

[0003] In order to overcome the problem that during the use of the female head connector, in a compact space area, it is not convenient to change the angle of the female receiver, resulting in inconvenient insertion work for the female receiver.

[0004] The technical solution of the utility model is: a USB female head connector with a bent angle protection, which includes an outer rotation assembly; it also includes a rotation connection assembly, an inner rotation assembly, a limit assembly, and a receiving assembly; a rotation connection assembly for connection is arranged on the outer rotation assembly; an inner rotation assembly for rotation limit connection is arranged on the rotation connection assembly; a fixed limit assembly for connection is arranged on the inner rotation assembly; a receiving assembly for insertion operation is arranged on the limit assembly.

[0005] Preferably, by installing the device inside the machine, when bending reception is required, by moving the receiving assembly forward, when the elastic structure on the limit assembly is adapted to the limit position on the receiving assembly, the inner rotation assembly does not perform the limit work on the limit assembly, and the outer rotation assembly can drive the receiving assembly on the limit assembly to rotate forward, and the receiving angle can be changed flexibly, solving the problem that it is not convenient to use the traditional straight USB female head connector in a compact space area.

[0006] Preferably, the outer rotation assembly includes a rotation ring, a limit groove, and a first groove body; limit grooves are opened at the left and right ends of the rotation ring; a first groove body is opened on the inner wall of the rotation ring, and the rotation ring can rotate subsequently, and the subsequent interface angle of the female receiver can be changed.

[0007] Preferably, the rotating connection assembly includes a sector block, a limiting arc block, a rotating shaft, and a mounting block; two sector blocks are arranged on the outer walls of the left and right ends of the rotating ring; a limiting arc block is fixedly connected to one end of the two sector blocks close to each other; the limiting arc block is adapted to the limiting groove; a rotating shaft is fixedly connected to one end of the sector block facing the axis of the rotating ring; mounting blocks are fixedly connected to the left and right ends of the limiting arc block. The rotating ring can be clamped by the limiting arc blocks on the two sector blocks, and the device can be conveniently installed through the mounting blocks.

[0008] Preferably, the inner rotating assembly includes a rotating column, a limiting convex block, and a second groove; a rotating column is arranged on the outer wall of the rotating shaft; second grooves are formed through the left and right ends of the rotating column; uniformly distributed limiting convex blocks are fixedly connected to the outer wall of the rotating column; the inner wall of the second groove is fixedly connected to the outer wall of the rotating shaft. Through the uniformly fixed limiting convex blocks on the outer wall of the rotating column, it is convenient to indirectly fix the rotating ring subsequently.

[0009] Preferably, the limiting assembly includes a first fixing block, a third groove, a fixing column, a movable plate, a convex column, a spring, a second fixing block, and a fourth groove; first fixing blocks are fixedly connected to the left and right ends of the rotating ring; a third groove is formed in the upper end of the first fixing block; fixing columns are fixedly connected to the inner walls of the front and rear ends of the third groove; a movable plate is rotatably arranged on the outer wall of the fixing column; a convex column and a second fixing block are fixedly connected to the upper end of the movable plate; the second fixing block is located in the first groove; a spring is fixedly connected to the upper end of the first fixing block; the other end of the spring is fixedly connected to the lower end of the movable plate; a fourth groove is formed in the upper end of the second fixing block; the fourth groove is adapted to the limiting convex block. By keeping the lower end of the inner wall of the movable plate parallel to the inner wall of the third groove, the inner wall of the fourth groove on the second fixing block is attached to the outer wall of the limiting convex block, so that the rotating ring can be kept stationary. When the convex column on the movable plate moves upward, the second fixing block moves downward through the movable plate, so that the rotating ring can rotate around the rotating shaft.

[0010] Preferably, the receiving assembly includes a female connector, a third fixing block, a fifth groove, a sixth groove, and a stop block; a female connector is arranged below the rotating ring; two third fixing blocks are fixedly connected to the upper end of the female connector; a fifth groove is formed in one end of the two third fixing blocks close to each other; a sixth groove is formed through the upper end of the third fixing block; stop blocks are fixedly connected to the front and rear ends of the third fixing block. By moving the female connector and the two third fixing blocks forward, the convex column on the movable plate is elastically inserted into the inner wall of the sixth groove through the spring, so that the movable plate rotates left and right, so that the rotating ring can rotate on the outer wall of the rotating shaft. When the rotating ring rotates, it will drive the female connector to change the angle along the rotating shaft. When storage is required, by moving the female connector backward, the convex column moves downward, keeping the movable plate parallel, and the limiting convex block is inserted into the fourth groove to fix the rotating ring.

[0011] Preferably, the upper and lower ends of the first fixing block are respectively attached to the upper and lower ends of the fifth groove body.

[0014] 2. By moving the female head connector and the two third fixing blocks forward, the convex column on the movable plate pops into the inner wall of the sixth groove body through the spring, so that the movable plate rotates left and right, so that the rotating ring can rotate on the outer wall of the rotating shaft.
