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 the mounting plate, the plug is connected to the wire, the socket is provided with a conductive sheet, the plug is provided with a conductive block, and the conductive block is provided with a conductive slot for inserting the conductive sheet; when the plug is inserted into the socket, the conductive sheet is inserted into the conductive slot, thereby realizing the connection between the plug and the socket.

[0004] Since the conductive block and the conductive sheet are directly connected, if water enters the connector due to human error, the connector is easily damaged, affecting the normal use of subsequent connectors, and may even cause the electronic control system to malfunction and lead to a car accident. Therefore, the connector needs to provide waterproof performance. Summary of the Invention

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

[0006] This application provides a high-current connector for automobiles, which adopts the following technical solutions:

[0007] A high-current connector for automobiles includes a plug and a socket. The socket is provided with a conductive sheet, the plug is provided with a conductive block, the conductive block is provided with a conductive slot for inserting the conductive sheet, the socket is provided with a connecting block, the connecting block is provided with a connecting slot for inserting the conductive block, and the conductive sheet is arranged in the connecting slot.

[0008] 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 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.

[0009] Optionally, a ring groove is provided on the plug, a waterproof ring for abutting the mounting plate is provided in the ring groove, and the waterproof ring protrudes from the ring groove.

[0010] By adopting the above technical solution, the waterproof ring is set 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 block and the conductive sheet, further enhancing the safety performance of the conductive block and the conductive sheet.

[0011] 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.

[0012] 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.

[0013] 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 the ring groove.

[0014] By adopting the above technical solution, the movable block is inserted into the movable groove, so that the fixing bar can drive the waterproof ring to move. If the fixing bar is inserted into the fixed 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, allowing the waterproof ring to further deform toward the mounting plate, so that the waterproof ring can be closer to the mounting plate, and further allowing the waterproof ring to limit the movement of water along the surface of the mounting plate.

[0015] Optionally, a limiting strip is slidably connected to the plug, a limiting hole is provided on the fixing strip for inserting the limiting strip, a limiting slope is provided on the limiting hole, the limiting slope is located in the insertion path of the limiting strip, and the distance between the limiting slope and the fixing spring gradually increases along the insertion direction of the limiting strip; when the limiting strip is inserted into the limiting hole, the fixing strip disengages from the fixing groove.

[0016] By adopting the above technical solution, the staff slides the limit bar to insert it 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 fixed spring gradually increases along the insertion direction of the limit bar, the limit bar can drive the fixed bar to move along the limit slope, allowing the fixed bar to disengage from the fixed groove, releasing the limit of the fixed bar on the connecting block, so that the plug can be removed from the socket.

[0017] 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.

[0018] 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 socket to separate.

[0019] 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.

[0020] By adopting the above technical solution, the stop bar is inserted into the stop hole, so that 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.

[0021] Optionally, an accommodating spring is provided in the accommodating groove, and an accommodating block is provided on the accommodating spring, and the accommodating spring drives the accommodating block to protrude from the accommodating groove; when the stop bar disengages from the stop hole, the limit bar moves from the second sliding groove to the first sliding groove.

[0022] By adopting the above technical solution, the accommodating block is driven to move by the accommodating spring, 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 moving the limit bar from the second sliding slot to the first sliding slot. The staff does not need to manually drive the limit bar to move again, 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 limiting hole.

[0023] Optionally, a through hole is provided on the fixing bar for inserting the stop bar; when the stop bar is inserted into the through hole, the stop bar can be located in the stop hole, and at this time the fixing bar is located in the fixing groove.

[0024] 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 fixed to the connecting block more stably, avoiding the fixing spring from being separated from the fixing groove due to elastic fatigue.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 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 directly contacting the conductive sheet and the conductive block, making the connection between the conductive block and the conductive sheet more stable, and making the conductive block and the conductive sheet less likely to be damaged by water.

[0027] 2. By inserting the movable block into the movable 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, allowing the waterproof ring to further deform toward the mounting plate, thereby allowing the waterproof ring to get closer to the mounting plate, further allowing the waterproof ring to restrict water from moving along the surface of the mounting plate.

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] Example 1

[0038] This embodiment discloses a high current connector for automobiles. Figure 1 A high-current connector for automobiles includes a plug 1 and a socket 2, wherein the socket 2 is bolted to a mounting plate. The plug 1 is inserted into the socket 2 to achieve circuit connectivity.

[0039] Reference Figure 2 A connection block 21 is fixedly connected to the surface of the socket 2 , a connection groove 211 is opened on the surface of the connection block 21 , and two conductive sheets 22 are fixedly connected in the connection groove 211 .

[0040] Reference Figure 2 and Figure 3 The plug 1 has a placement slot 11 on its surface for inserting a connection block 21. Two conductive blocks 12 are fixedly connected to the plug 1. Each conductive block 12 has a conductive slot 121 on its surface for inserting a conductive sheet 22. When the conductive sheet 22 is inserted into the conductive slot 121, the conductive block 12 is located within the connection slot 211.

[0041] Reference Figure 3 The surface of the plug 1 facing the mounting plate has an annular groove 13, into which a waterproof ring 131 is fixedly connected, protruding from the groove 13. A groove 132 is defined on the surface of the waterproof ring 131 facing away from the bottom wall of the groove 13. The groove 132 extends along the circumference of the waterproof ring 131. When the plug 1 is inserted into the socket 2, the waterproof ring 131 is positioned outside the connecting block 21 and deforms toward the groove 132, allowing the waterproof ring 131 to more tightly abut the mounting plate.

[0042] The implementation principle of Example 1 is as follows: by inserting the connecting block 21 into the placement groove 11, and the waterproof ring 131 abutting against the mounting plate, the interference and damage of water to the connector is reduced.

[0043] Example 2

[0044] Reference Figure 4 and Figure 5 This embodiment differs from the first embodiment in that a receiving groove 14 is formed on the wall of the placement groove 11 and communicates with the annular groove 13. A fixing spring 141 is provided on the wall of the receiving groove 14. One end of the fixing spring 141 is fixedly connected to the bottom wall of the receiving groove 14, and the other end of the fixing spring 141 is fixedly connected to a fixing bar 142. A fixing groove 23 is formed on the surface of the connecting block 21 for inserting the fixing bar 142. The fixing spring 141 drives the fixing bar 142 into the fixing groove 23.

[0045] Reference Figure 5 A fixing slope 143 is provided on the surface of the fixing strip 142 away from the fixing spring 141 . The distance between the fixing slope 143 and the bottom wall of the accommodating groove 14 gradually decreases along the insertion path of the plug 1 , and the fixing slope 143 is located on the moving path of the connecting block 21 .

[0046] Reference Figure 5 When the plug 1 is inserted into the socket 2, the connecting block 21 drives the fixing bar 142 to move through the fixing inclined surface 143, so that the connecting block 21 is located in the placement groove 11. At this time, the fixing spring 141 drives the fixing bar 142 to insert into the fixing groove 23, so that the fixing bar 142 and the connecting block 21 are fixed to each other.

[0047] Reference Figure 5 The waterproof ring 131 has a movable groove 133 on its surface facing the accommodating groove 14, and a movable block 144 is fixedly connected to the surface of the fixing bar 142. The movable block 144 can be inserted into the movable groove 133. The staff installs the waterproof ring 131 in the ring groove 13, and the movable block 144 is inserted into the movable groove 133. Then, the fixing bar 142 is inserted into the fixing groove 23. The fixing bar 142 drives the waterproof ring 131 to deform toward the connecting block 21 through the movable block 144, so that the waterproof ring 131 and the mounting plate can be more tightly connected.

[0048] Reference Figure 4 and Figure 6The surface of the plug 1 is provided with a first sliding groove 15 and a second sliding groove 151. The first sliding groove 15 is connected to the second sliding groove 151. The first sliding groove 15 extends in the direction in which the plug 1 is inserted into the socket 2. The second sliding groove 151 includes a first portion 153 and a second portion 154. The first portion 153 extends in the direction in which the plug 1 is inserted into the socket 2 and is shorter than the length of the first sliding groove 15. The second portion 154 extends from the first portion 153 in a direction away from the socket 2 and is inclined along the direction from the first portion 153 to the second sliding groove 151.

[0049] Reference Figure 6 The first sliding groove 15 is slidably connected to the limiting block 31, and the limiting block 31 can slide into the second sliding groove 151. The limiting block 31 is fixedly connected to the limiting strip 3, and the limiting strip 3 extends along the length direction of the first sliding groove 15.

[0050] Reference Figure 5 and Figure 6 The surface of the plug 1 is provided with a receiving hole 16 that communicates with the receiving groove 14. The receiving hole 16 is provided for the insertion of the limiting strip 3. The surface of the fixing strip 142 is provided with a limiting hole 145 for the insertion of the limiting strip 3. The wall of the limiting hole 145 is provided with a limiting slope 146. The distance between the limiting slope 146 and the fixing spring 141 gradually increases along the direction from the receiving hole 16 to the receiving groove 14, and the limiting slope 146 is located in the insertion path of the limiting strip 3.

[0051] Reference Figure 5 and Figure 6 When the fixing bar 142 is inserted into the fixing groove 23, the staff slides the limiting bar 3 to allow the limiting bar 3 to be inserted into the accommodating hole 16. At this time, the limiting bar 3 drives the fixing bar 142 out of the fixing groove 23 through the limiting inclined surface 146, allowing the fixing bar 142 to release the lock on the connecting block 21.

[0052] Reference Figure 6 and Figure 7 The surface of the plug 1 is provided with a receiving groove 17 for inserting the limit bar 3. A movable hole 174 is provided on the surface of the plug 1, communicating with the receiving groove 17. A stop bar 171 is slidably connected to the movable hole 174. A stop hole 32 is provided on the surface of the limit bar 3, through which the stop bar 171 passes. An extension block 148 is integrally formed on the surface of the fixing bar 142. A through hole 147 is provided on the surface of the extension block 148, through which the stop bar 171 passes.

[0053] Reference Figure 5 、 Figure 6 and Figure 7When the limiting strip 3 is inserted into the limiting hole 145, the limiting block 31 is located in the first sliding groove 15. When the limiting strip 3 is inserted into the receiving groove 17, the limiting block 31 is located in the first portion 153. The staff slides the stop strip 171 and inserts it into the stop hole 32 and the through hole 147. At this time, the stop strip 171 limits the limiting strip 3 and the fixing strip 142, preventing the limiting strip 3 from being separated from the receiving groove 17 and the fixing strip 142 from being separated from the connecting block 21.

[0054] Reference Figure 6 and Figure 7 An accommodating spring 172 is fixedly connected to the bottom wall of the accommodating groove 17. A accommodating block 173 is fixedly connected to the surface of the accommodating spring 172 away from the bottom wall of the accommodating groove 17. The accommodating spring 172 drives the accommodating block 173 to protrude from the accommodating groove 17. When the accommodating block 173 protrudes from the accommodating groove 17, the accommodating spring 172 is in a non-stressed state; when the accommodating block 173 is located in the accommodating groove 17, the accommodating spring 172 is in a compressed state.

[0055] Reference Figure 6 and Figure 7 When the limit bar 3 is inserted into the receiving groove 17, the receiving spring 172 is in a compressed state. At this time, the receiving spring 172 pushes the limit bar 3 out of the receiving groove 17 through the receiving block 173, allowing the limit block 31 to move from the first part 153 to the second part 154. Due to the inclination of the second part 154, the limit block 31 can move from the second part 154 to the first sliding groove 15.

[0056] The implementation principle of Example 2 is as follows: the staff slides the stop bar 171, allowing the accommodating spring 172 to drive the limit bar 3 to disengage from the accommodating groove 17, allowing the limit bar 3 to move from the first part 153 to the first sliding groove 15, and then the staff slides the limit bar 3, allowing the limit bar 3 to be inserted into the limiting hole 145, so that the limit bar 3 drives the fixing bar 142 to disengage from the fixing groove 23, so that the plug 1 can be disengaged from the socket 2.
