Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a high-current connector for automobiles. Background Art

[0002] A connector is an electronic component used to connect two active devices. It is mainly used to transmit current and optical signals, and to prevent signal distortion and energy loss between systems. Connectors are usually installed in automobiles as an important interface for signal or current transmission.

[0003] In the related technology, the connector includes a plug and a socket, the socket is fixed on a mounting plate, the plug is connected to the wire, a conductive sheet is provided on the socket, a conductive block is provided on the plug, and a conductive groove is provided on the conductive block for inserting the conductive sheet; when the plug is inserted into the socket, the conductive sheet is inserted into the conductive groove to achieve connection between the plug and the socket.

[0004] Since the conductive block and the conductive sheet are directly connected, if the connector is exposed to water due to human factors, the connector is easily damaged, affecting the normal use of subsequent connectors, and may even cause failures in the electronic control system and lead to traffic accidents. Therefore, it is necessary to provide waterproof performance for the connector. Summary of the invention

[0005] In order to improve the waterproof performance of the connector, the present application provides a high-current connector for automobiles.

[0006] The present application provides a high current connector for automobiles, which adopts the following technical solution: A high-current connector for automobiles comprises a plug and a socket, wherein the socket is provided with a conductive sheet, the plug is provided with a conductive block, the conductive block is provided with a conductive groove for inserting the conductive sheet, the socket is provided with a connecting block, the connecting block is provided with a connecting groove for inserting the conductive block, and the conductive sheet is arranged in the connecting groove.

[0007] By adopting the above technical solution, the conductive block is inserted into the connecting groove, and the connecting block protects the conductive block, so that the connection between the conductive block and the conductive sheet can be more secure, reducing the possibility of people forcibly bending the conductive block and the conductive sheet by external force, and avoiding water from directly contacting the conductive sheet and the conductive block, so that the connection between the conductive block and the conductive sheet can be more stable, and the conductive block and the conductive sheet are not easily damaged by water.

[0008] Optionally, a ring groove is provided on the plug, a waterproof ring for abutting against the mounting plate is provided in the ring groove, and the waterproof ring protrudes from the ring groove.

[0009] By adopting the above technical solution, the waterproof ring is arranged in the ring groove, and the waterproof ring protrudes from the ring groove, so that the waterproof ring can abut the mounting plate, so that the waterproof ring can limit the flow of water along the mounting plate, making it difficult for water to contact the conductive blocks and conductive sheets, thereby further enhancing the safety performance of the conductive blocks and conductive sheets.

[0010] Optionally, the plug is provided with a fixing spring, the fixing spring is provided with a fixing strip, the connecting block is provided with a fixing groove for inserting the fixing strip, and the fixing spring drives the fixing strip to be inserted into the fixing groove; when the fixing strip is inserted into the fixing groove, the plug and the socket are fixed to each other.

[0011] By adopting the above technical solution, the fixing strip is driven to move by the fixing spring, and the fixing strip is inserted into the fixing groove, so that the groove wall of the fixing groove limits the fixing strip, thereby allowing the fixing strip to limit the movement of the connecting block, so that the connecting block can be stably located on the plug, avoiding the possibility of separation of the plug and the socket.

[0012] Optionally, a moving block is provided on the fixing bar, and a moving groove for inserting the moving block is opened on the waterproof ring; when the moving block is inserted into the moving groove and the fixing bar is located in the fixing groove, the waterproof ring abuts against the ring groove.

[0013] By adopting the above technical solution, the moving block is inserted into the moving groove, so that the fixing bar can drive the waterproof ring to move. If the fixing bar is inserted into the fixing groove, the fixing bar drives the waterproof ring to move toward the connecting block, so that the waterproof ring can abut the ring groove. At this time, the waterproof ring is squeezed and deformed, so that the waterproof ring can further deform toward the mounting plate, so that the waterproof ring can be closer to the mounting plate, and further the waterproof ring can limit the movement of water along the surface of the mounting plate.

[0014] Optionally, a limit strip is slidably connected to the plug, a limit hole is provided on the fixing strip for inserting the limit strip, a limit slope is provided on the limit hole, the limit slope is located in the insertion path of the limit strip, and the distance between the limit slope and the fixing spring gradually increases along the insertion direction of the limit strip; when the limit strip is inserted into the limit hole, the fixing strip disengages from the fixing groove.

[0015] By adopting the above technical solution, the staff slides the limit bar to insert the limit bar into the limit hole. Since the limit slope is located in the insertion path of the limit bar and the distance between the limit slope and the fixing spring gradually increases along the insertion direction of the limit bar, the limit bar can drive the fixing bar to move along the limit slope, so that the fixing bar can be separated from the fixing groove, thereby releasing the fixing bar from limiting the connecting block, so that the plug can be removed from the socket.

[0016] Optionally, a first sliding groove is provided on the plug, a second sliding groove connected to the first sliding groove is provided on the plug, the limit bar is slidably connected in the first sliding groove and the second sliding groove, and a receiving groove for inserting the limit bar is provided on the plug; when the limit bar is inserted into the receiving groove, the limit bar is located in the second sliding groove; when the limit bar is inserted into the limiting hole, the limit bar is located in the first sliding groove.

[0017] By adopting the above technical solution, the limit bar is moved from the first sliding groove to the second sliding groove, and the limit bar is inserted into the accommodating groove, so that the limit bar cannot be directly inserted into the limit hole, thereby preventing outsiders from accidentally touching the limit bar and reducing the possibility of the limit bar driving the fixed bar to move and causing the plug and the socket to separate.

[0018] Optionally, a stop bar is slidably connected in the accommodating groove, and a stop hole for the stop bar to pass through is opened on the limiting bar; when the stop bar passes through the stop hole, the stop bar is fixed in the accommodating groove.

[0019] By adopting the above technical solution, the stop bar is inserted into the stop hole, and the stop bar limits the limit bar, making it difficult for the limit bar to separate from the receiving groove, so that the limit bar will not separate from the receiving groove due to shaking, further increasing the stability of the limit bar in the receiving groove.

[0020] Optionally, an accommodating spring is provided in the accommodating groove, an accommodating block is provided on the accommodating spring, and the accommodating spring drives the accommodating block to protrude out of the accommodating groove; when the stop bar is disengaged from the stop hole, the limit bar moves from the second sliding groove to the first sliding groove.

[0021] By adopting the above technical solution, the accommodating spring drives the accommodating block to move, and the accommodating spring drives the accommodating block to protrude from the accommodating slot, so that the accommodating block can push the limit bar out of the accommodating slot, thereby the limit bar moves from the second sliding slot to the first sliding slot. The staff does not need to manually drive the limit bar to move again, thereby reducing the staff's operating steps, so that the staff can quickly push the limit bar so that the limit bar can be inserted into the limit hole.

[0022] Optionally, the fixing strip is provided with a through hole for inserting the stop strip; when the stop strip is inserted into the through hole, the stop strip can be located in the stop hole, and at this time the fixing strip is located in the fixing groove.

[0023] By adopting the above technical solution, the stop bar is inserted into the through hole so that the stop bar can limit the fixing bar. At this time, the fixing bar is located in the fixing groove. The stop bar limits the fixing bar so that the fixing bar can be more stably fixed to the connecting block, thereby preventing the fixing bar from being separated from the fixing groove due to elastic fatigue of the fixing spring.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By inserting the conductive block into the connecting groove, the connecting block protects the conductive block, making the connection between the conductive block and the conductive sheet more secure, reducing the possibility of people forcibly bending the conductive block and the conductive sheet by external force, and avoiding water from directly contacting the conductive sheet and the conductive block, making the connection between the conductive block and the conductive sheet more stable, and preventing the conductive block and the conductive sheet from being damaged by water.

[0025] 2. By inserting the moving block into the moving groove, the fixing bar can drive the waterproof ring to move. If the fixing bar is inserted into the fixing groove, the fixing bar drives the waterproof ring to move toward the connecting block, so that the waterproof ring can abut the ring groove. At this time, the waterproof ring is squeezed and deformed, so that the waterproof ring can further deform toward the mounting plate, so that the waterproof ring can be closer to the mounting plate, and further allow the waterproof ring to limit the movement of water along the surface of the mounting plate.
