Description

Technical Field

[0001] The utility model relates to the technical field of rectangular connectors, in particular to a rectangular connector connection structure. Background Art

[0002] Rectangular connectors, as the name implies, are a type of connector with a rectangular design. They are widely used in electronic devices, especially on printed circuit boards. This type of connector has a simple design and compact structure, and can achieve board-to-board or component-to-component connection.

[0003] Rectangular connectors usually consist of a plug (male) and a socket (female). The socket is generally connected to the housing of the corresponding device by screws and connected to the corresponding circuit board in the device. Some sockets are directly fixed to the circuit board and then pass through the holes reserved in the device housing for connection. The plug is generally connected to the connecting line of the external device, and the corresponding two devices are connected through the connection between the plug and the socket.

[0004] The main function of a rectangular connector is to transmit signals or electrical energy in a circuit, and can connect or disconnect the circuit.

[0005] The plug (male) and socket (female) of the current rectangular connector are fixed with screws when connected to increase the stability after the connection, such as the connection plug and socket of the connection line between the computer display and the host;

[0006] However, when connecting, the connecting end of the thread is prone to loosening. Once loosened, it is difficult to fix and disassemble, and the connection is prone to instability, which brings inconvenience to subsequent use.

[0007] At the same time, it is easy to over-tighten after connection, or tighten it but not fix it completely. Over-tightening will make subsequent disassembly inconvenient, and tightening it but not fix it completely will make it loose, which is easy to have poor contact and bring inconvenience to the user.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] A rectangular connector connection structure includes a plug 10 and a socket 20. The circuits and circuit structures of the plug 10 and the socket 20 can adopt the structure of an existing rectangular connector.

[0044] In the examples of this application, please refer to Figure 1 and 2 , both sides of the socket 20 are provided with connection structures 30, and both sides of the plug 10 are provided with limiting structures 40 corresponding to the connection structures 30 one by one;

[0045] For further information, see Figure 1 , 2 , 3 and 4, the connection structure 30 includes a connection column 31 arranged on the side of the socket 20 close to the plug 10, the connection column 31 is fixedly connected to a threaded rod 32, the threaded rod 32 is threadedly connected to the socket 20, and a plurality of limiting grooves 33 are provided on the side of the connection column 31. The limiting groove 33 is arranged in an annular shape, and the side close to the plug 10 is a plane, and the side away from the plug 10 is an inclined surface. Figure 3 As shown;

[0046] Furthermore, the limiting structure 40 includes a connecting block 41 disposed on the side of the plug 10 close to the socket 20, a rotating shaft 43 is fixed inside the connecting block 41, and one end of the movable rod 42 is rotatably connected to the outside of the rotating shaft 43. Figure 4 As shown, a torsion spring 44 is sleeved on the outside of the rotating shaft 43, one end of the torsion spring 44 extends to the inside of the movable rod 42, and the other end extends to the inside of the rotating shaft 43 and is in a twisted state, and a limit block 45 adapted to the limit groove 33 is fixed to the other end of the movable rod 42, and a handle 46 is fixedly connected to the movable rod 42;

[0047] When in use, the handle 46 is pulled to drive the movable rod 42 and the limit block 45 to rotate around the rotating shaft 43, and then the plug 10 is inserted into the socket 20. After it is inserted tightly, the handle 46 is released. Under the action of the restoring force of the torsion spring 44, the movable rod 42 and the limit block 45 can be driven to reset, and the limit block 45 can enter the interior of the limit groove 33, and then the limitation can be completed. Otherwise, the limitation can be cancelled, and then the plug 10 can be pulled out. The operation is simple, and there will be no slipping, loosening or instability. The installation and disassembly process is also simpler and more convenient, which is more convenient for users to connect and use after connection.

[0048] In another embodiment, see Figure 1 , 2 , 3 and 4, an adjustment structure 50 is provided at the plug 10, and the adjustment structure 50 is transmission-connected with the connecting block 41. Specifically, the adjustment structure 50 includes a fixed sleeve 51 fixed to the side of the plug 10, and a movable hole 52 is provided inside the fixed sleeve 51 and the plug 10. The opening of the movable hole 52 is aligned with the socket 20, and a movable column 53 fixedly connected to the connecting block 41 is slidably provided inside the movable hole 52. To prevent the movable column 53 from rotating, the movable column 53 is a square column, and the movable hole 52 is a square hole;

[0049] A rotating rod 54 is rotatably disposed inside the fixed sleeve 51 through a bearing 56. One end of the rotating rod 54 is fixedly connected to a threaded column 55. The threaded column 55 is threadedly connected to the inside of the movable column 53. The other end of the rotating rod 54 is fixed to a knob 57 located outside the fixed sleeve 51.

[0050] After connecting in the above manner, if there is a problem with the distance causing an unstable connection, the knob 57 can be turned to drive the rotating rod 54 and the threaded column 55 to rotate, thereby driving the movable column 53 to slide, and then driving the connecting block 41 to slide, and finally driving the movable rod 42 and the limit block 45 to slide, so that it can adapt to different locking requirements, ensure normal locking, and ensure stability after connection.
