Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically an electrical connector and its fixing device. Background Technology

[0002] With the continuous improvement of national electrification levels, the use of electrical connectors is becoming increasingly widespread. Electrical connectors play a crucial role in electrical systems, and their performance and quality directly affect the safety and reliability of the entire system. An electrical connector is a component used to connect two active devices to transmit current or signals; it is also called a plug, connector, or joint. For a typical structure, see Chinese Patent CN202122721039.0.

[0003] When existing electrical connectors are connected to the electrical sockets of appliances, if the user accidentally touches the connector wires, the wires will loosen the connection between the connector and the appliance socket, resulting in poor stability of the power transmission from the connector to the appliance. Utility Model Content

[0004] This utility model provides an electrical connector and its fixing device, aiming to solve the problems mentioned in the background art, such as when the user accidentally touches the connector wire when the existing electrical connector is connected to the electrical socket of the appliance, the wire will cause the connector to loosen from the appliance socket.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electrical connector and its fixing device, comprising a connector body and a fixing structure installed on an electrical appliance, wherein an electrical wire is installed on the connector body;

[0006] The fixing structure includes two symmetrically mounted support frames on the side wall of the appliance. A crossbar is installed inside the support frame, and a spring is sleeved on the outer wall of each crossbar. Arc-shaped plates are slidably mounted on both sides of the outer wall of the two crossbars. Connecting plates are symmetrically mounted on both sides of the outer wall of each arc-shaped plate. A limit ring is rotatably mounted on the lower connecting plate through a mounting hole, and an opening is provided on the side wall of the upper connecting plate. By setting up the fixing structure, the arc-shaped plates on both sides are pressed towards the connector body, causing the arc-shaped plates to lock into the limit groove. The end of the rotating limit ring away from the lower connecting plate passes over the arc-shaped protrusion and is locked in the opening, thus fixing the position of the connector body. This avoids the problem of users accidentally touching the connector wires when the electrical connector is connected to the appliance's power socket, causing the wires to loosen the connector from the appliance socket, thus improving the stability of the connector body's power transmission to the appliance.

[0007] Preferably, a protective structure is installed on the side wall of the electrical appliance and outside the fixed structure;

[0008] The protective structure includes a corrugated pipe installed on the side wall of the electrical appliance and a sealing cover rotatably installed on the outer wall of the wire. The end of the corrugated pipe away from the electrical appliance is provided with an external threaded cylinder, and the inner wall of the sealing cover is provided with an internal thread that matches the external threaded cylinder.

[0009] Preferably, the outer wall of the connector body is provided with a limiting groove that is adapted to the arc-shaped plate, and the connector plate is provided with an arc-shaped protrusion inside the opening.

[0010] Preferably, the connecting plate is slidably connected to the outer wall of the crossbar through the first through hole, and the two ends of the spring are respectively connected to the upper and lower connecting plates.

[0011] Preferably, the side wall of the electrical appliance is provided with a plug-in interface, and the electrical appliance is plugged into and detached from the connector body through the plug-in interface.

[0012] Preferably, the sealing cover has a second through hole at its center for rotatable connection with the wire.

[0013] Beneficial effects: By setting a fixed structure, the upper and lower arc-shaped plates are pressed towards the connector body, causing the arc-shaped plates to lock into the limiting groove. The end of the limiting ring away from the lower connecting plate is rotated to pass over the arc-shaped protrusion and lock into the opening, thus fixing the position of the connector body. This avoids the problem that when the user accidentally touches the connector wire when the existing electrical connector is connected to the electrical socket, the wire will cause the connector to loosen from the electrical socket. This makes the connection between the connector body and the socket more secure and improves the stability of the connector body in transmitting power to the electrical appliance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] An electrical connector and its fixing device, such as Figure 1-5 As shown, the connector and its fixing device include a connector body 2 and a fixing structure 3 installed on the electrical appliance 1, and a wire 4 is installed on the connector body 2;

[0022] The fixed structure 3 includes two support frames 31 symmetrically mounted on the side wall of the appliance 1. A crossbar 32 is installed in the inner cavity of the support frame 31. A spring 33 is sleeved on the outer wall of the crossbar 32. An arc plate 34 is slidably mounted on both sides of the outer wall of the two crossbars 32. A connecting plate 341 is symmetrically mounted on both sides of the outer wall of the arc plate 34. A limit ring 35 is rotatably mounted on the lower connecting plate 341 through the mounting hole 3411. An opening 3412 is opened on the side wall of the upper connecting plate 341.

[0023] In use, the user presses the upper and lower arc plates 34 towards the connector body 2. The arc plates 34 drive the connecting plates 341 on both sides to slide on the outer wall of the crossbar 32, so that the upper and lower arc plates 34 are locked in the limiting groove 21. The user rotates the limiting ring 35 so that the end of the limiting ring 35 away from the lower connecting plate 341 passes over the arc protrusion 3413 and is locked in the opening 3412, so that the position of the upper and lower connecting plates 341 is fixed, thus the upper and lower arc plates 34 are tightly locked in the limiting groove 21, thereby fixing the position of the connector body 2. This avoids the problem that when the existing electrical connector is connected to the electrical socket of the appliance 1, the user may accidentally touch the connector wire, and the wire will cause the connector to loosen from the socket of the appliance 1. This makes it impossible for the touching wire 4 to move the connector body 2. The connection between the connector body 2 and the socket 11 is more secure, and the stability of the power transmission of the connector body 2 to the appliance 1 is improved.

[0024] The spring 33 drives the limiting ring 35 away from the opening 3412, causing the upper and lower connecting plates 341 to be unrestricted. Under the reset action of the spring 33, the spring 33 drives the upper and lower connecting plates 341 to move away from each other. The connecting plates 341, along with the arc plate 34, move away from the limiting groove 21, thereby increasing the distance between the two arc plates 34, which facilitates the insertion and removal of the connector body 2 in the insertion interface 11.

[0025] In this embodiment, a limiting groove 21 adapted to the arc plate 34 is provided on the outer wall of the connector body 2, and an arc protrusion 3413 is provided on the connecting plate 341 inside the opening 3412; the connecting plate 341 is slidably connected to the outer wall of the crossbar 32 through the first through hole 3414, and the two ends of the spring 33 are respectively connected to the upper and lower connecting plates 341.

[0026] The arc-shaped protrusion 3413 allows the end of the limiting ring 35 away from the lower connecting plate 341 to pass over the arc-shaped protrusion 3413 and be stuck in the opening 3412. The arc-shaped protrusion 3413 restricts the position of the limiting ring 35 without human operation, thereby increasing the stability of the fixing structure 3 in fixing the position of the connector body 2.

[0027] In this embodiment, the side wall of the electrical appliance 1 is provided with a plug interface 11, and the electrical appliance 1 is plugged and unplugged into the connector body 2 through the plug interface 11.

[0028] A protective structure 5 is installed on the side wall of the electrical appliance 1 and outside the fixed structure 3;

[0029] The protective structure 5 includes a bellows 51 installed on the side wall of the electrical appliance 1 and a sealing cover 52 rotatably installed on the outer wall of the wire 4. The end of the bellows 51 away from the electrical appliance 1 is provided with an external threaded cylinder 53, and the inner wall of the sealing cover 52 is provided with an internal thread 54 that is adapted to the external threaded cylinder 53.

[0030] In use, the corrugated pipe 51 is compressed towards the appliance 1 so that it does not obstruct the fixing structure 3. The connector body 2 passes through the middle of the upper and lower arc plates 34 and is inserted into the plug interface 11. The user operates the fixing structure 3 to clamp and fix the position of the connector body 2, and then stretches the corrugated pipe 51 away from the appliance 1 so that the corrugated pipe 51 completely surrounds the outside of the connector body 2. The corrugated pipe 51 drives the external threaded cylinder 53 to contact the sealing cover 52, and drives the sealing cover 52 to rotate on the outer wall of the wire 4, so that the internal thread 54 and the external threaded cylinder 53 are threadedly connected, so that the connection between the connector body 2 and the plug interface 11 is sealed by the corrugated pipe 51, the sealing cover 52 and the external threaded cylinder 53.

[0031] To prevent dust from falling on the connector body 2 and the connection point with the plug interface 11 and entering the plug interface 11, thus preventing corrosion of the connector body 2 and the plug interface 11, and also to prevent water from falling on the connection point between the plug interface 11 and the connector body 2, causing a short circuit between the electrical appliance 1 and the connector body 2, damaging the electrical appliance 1 and the circuit, thus achieving waterproof and dustproof protection at the connection point between the electrical appliance 1 and the connector body 2, making the power transmission effect of the connector body 2 to the electrical appliance 1 better;

[0032] In this embodiment, a second through hole 521 for rotatably connecting with the wire 4 is provided at the center of the sealing cover 52.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
