Description

Technical Field

[0001] The invention relates to the technical field of automobile line end connectors, in particular to an automobile line end connector. Background Art

[0002] Automotive line connectors play a vital role in the automotive electrical system. They are mainly used to connect wires and electrical devices to ensure that the various components of the vehicle electrical system can work properly. The main functions and uses of vehicle line connectors include connecting wires and electrical devices, improving the stability and reliability of electrical connections, and simplifying the circuit connection process.

[0003] A sealing plug is usually provided inside the automotive wire-end connector, and a mounting hole for installing the terminal is opened on the sealing plug. Most of the sealing plugs are made of oil-containing materials, which is mainly for lubrication. During assembly, the terminal can be installed more easily with the connector. However, if the sealing plug contains less oil, or the wiring harness factory places it in the buffer zone for too long after crimping, causing part of the lubricating oil to evaporate, the resistance will increase during the subsequent terminal assembly process. When auxiliary tools are not used, it is easy to tear the neck of the sealing plug, resulting in a decrease in the sealing performance of the sealing plug. In addition, the torn part of the neck of the sealing plug is relatively hidden, because the damaged position is usually difficult to observe after the terminal is implanted in the connector, making it impossible for the staff to discover the problem and deal with it in time, which in turn causes the sealing plug to fail to meet the sealing requirements during future use.

[0004] In response to the above problems, the prior art provides some solutions. For example, patent application number: CN202020843312.X provides a wiring harness connector and a wiring harness connector. A wiring harness connector includes a connector body, the connector body includes a receiving end for receiving the wiring harness and a plug-in end for plugging in a female connector, the receiving end and the plug-in end are connected and communicated; a circuit board is provided in the receiving end, a light source is provided on the circuit board, electrical interfaces connected to the plug-in end and the wiring harness are respectively provided on both sides of the circuit board, and a through hole corresponding to the light source is provided on the receiving end. A wiring harness connector adopts the above-mentioned wiring harness connector and also includes a female connector. The female connector and the wiring harness connector are connected in a detachable manner. Although this solution facilitates the installation between the female connector and the wiring harness connector, it does not solve the problem of scratching the sealing plug of the wiring harness connector when the lubricating oil is missing. Summary of the invention

[0005] The purpose of the present invention is to provide an automotive wire end connector to solve the problem that when there is a lack of lubricating oil in the sealing plug, the resistance to the terminal assembly process will become larger, and when no auxiliary tools are used, the neck of the sealing plug will be easily torn, resulting in a decrease in the sealing performance of the sealing plug.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A car wire end connector comprises a male connector and a female connector, wherein a sealing plug is fixedly installed inside the male connector, and two mounting holes are provided on the sealing plug, a fixing frame is also fixedly installed inside the male connector, a wiring harness terminal is also slidably connected inside the mounting hole, a buckle is also fixedly installed on the male connector, the female connector is slidably connected to the male connector, two mounting seats are symmetrically fixedly installed on the male connector, switches are slidably connected to the mounting seats, and an expansion component with a supporting block is also installed on the mounting seat, the number of the supporting blocks is 4, the four supporting blocks are respectively located on both sides of the sealing plug, and the supporting block is in contact with the inner wall of the mounting hole, and when the switch slides, the expansion component controls the supporting block to move toward the outside of the mounting hole.

[0008] It is easy to understand that the design sets an expansion component with a support block on the inner wall of the mounting hole. When the staff needs to assemble the wiring harness terminal, they can first control the expansion component through the switch, and then make the expansion component control the support block to move away from the mounting hole. During the movement of the support block, since the sealing plug is made of flexible material, the support block will squeeze the inner wall of the mounting hole. At this time, the inner wall of the mounting hole will expand outward due to the squeezing. At this time, the staff can smoothly insert the wiring harness terminal into the mounting hole, and due to the action of the support block, the pressure of the inner wall of the mounting hole on the wiring harness terminal is reduced, thereby avoiding the wiring harness terminal from scratching the inner wall of the mounting hole during installation. Therefore, the design saves the staff the step of using tools to prop up the mounting hole, and also avoids damage to the sealing plug by the wiring harness terminal during installation, which not only improves work efficiency, but also improves the reliability of the automotive wire end connector.

[0009] Preferably, the expansion component includes a control rod 1, a slider 1 is fixedly connected to the switch, the control rod 1 is slidably connected to the inside of the mounting seat, connecting rods 1 are fixedly installed at both ends of the control rod 1, connecting rods 2 are installed at both ends of the connecting rod 1, the support block 1 is fixedly connected to the connecting rod 2, an inclined surface 1 is provided at one end of the slider 1 close to the control rod 1, and a chamfer is provided on the control rod 1, and when the switch slides toward the side close to the fixed frame, the slider 1 approaches the control rod 1, the control rod 1 contacts the inclined surface 1 and the control rod 1 slides on the inclined surface 1.

[0010] It is easy to understand that when the staff slides the switch toward the side where the fixing bracket is located, the switch drives the slider 1 to slide. At this time, the inclined surface 1 on the slider 1 contacts the control rod 1, and the slider 1 continues to slide. The control rod 1 moves toward the outside of the mounting seat under the pressure of the inclined surface 1. At this time, the connecting rod 1 on both sides of the control rod 1 moves with the control rod 1, and the connecting rod 2 on both sides of the connecting rod 1 moves with the connecting rod 1, and the supporting block 1 on the connecting rod 2 will also move with the connecting rod 2. At this time, the supporting block 1 will squeeze the inner wall of the mounting hole to expand the mounting hole. The design structure is simple and compact, and the supporting block 1 is arc-shaped. It always fits with the inner wall of the mounting hole during the movement and will not cause damage to the sealing plug. Therefore, the design further improves the reliability of the automotive line end connector.

[0011] Preferably, a slider 2 is further provided inside the mounting seat, and the slider 2 is fixedly connected to the switch, and an inclined plane 2 is provided at one end of the slider 2 close to the control rod 1, and the control rod 1 is also provided with a chamfered angle, and when the switch slides toward the side away from the fixing frame, the slider 2 approaches the control rod 1, and the control rod 1 contacts the inclined plane 2 and slides on the inclined plane 2.

[0012] It is easy to understand that after the wiring harness terminal is installed, the staff can push the switch in the direction away from the fixing frame, and the inclined surface 2 on the slider 2 will squeeze the control rod 1, causing the control rod 1 to move. At this time, the connecting rod 1 on both sides of the control rod 1 and the connecting rod 2 connected to the connecting rod 1 will move together. At this time, the support block 1 on the connecting rod 2 will follow the connecting rod 2 to move toward the mounting hole. This design avoids the problem that after the expansion component completes the expansion of the mounting hole, the support block cannot be retracted due to the jamming of the internal structure, which in turn causes a gap between the mounting hole and the wiring harness terminal, reducing the sealing performance of the sealing plug. This design ensures that when the wiring harness terminal is installed, the support block can be completely retracted, and the support block 1 also presses the wiring harness terminal tightly, ensuring the fit between the sealing plug and the wiring harness terminal, thereby improving the sealing effect of the sealing plug.

[0013] Preferably, a sliding hole is provided on the mounting seat, the connecting rod 2 is slidably connected to the sliding hole, the connecting rod 2 is slidably connected to the connecting rod 1, a control rod 2 is further provided inside the mounting seat, both ends of the control rod 2 are respectively fixedly connected to the connecting rod 2, a rectangular hole is provided on the switch, a rectangular rod is fixedly connected to the control rod 2, the rectangular rod is slidably connected in the rectangular hole, a slider 3 is further fixedly connected inside the mounting seat, an inclined plane 3 is provided at one end of the slider 3 close to the control rod 2, when the switch slides toward the side close to the fixed frame, the slider 3 approaches the control rod 2, the control rod 2 contacts the inclined plane 3 and the control rod 2 slides on the inclined plane 3.

[0014] It is easy to understand that when the wiring harness terminal is installed, the staff pushes the switch in the direction away from the fixing frame. Since the connecting rod 2 is slidably connected to the connecting rod 1, the switch will drive the control rod 2 to move together, and since the connecting rod 2 is slidably connected to the connecting rod 1, the connecting rod 2 will move with the control rod 2. At this time, the support block on the connecting rod 2 will move with the connecting rod 2 and leave the mounting hole. This design allows the support block to move away from the mounting hole after the wiring harness terminal is installed, avoiding the support block from being clamped between the sealing plug and the wiring harness terminal, resulting in a gap between the inner wall of the mounting hole and the wiring harness terminal, and then causing the sealing effect of the sealing plug to decrease. Therefore, this design ensures the sealing effect of the sealing plug.

[0015] Preferably, the connecting rod 2 is also fixedly connected to a connecting rod 3, and a supporting block 2 is also provided on the inner wall of the mounting hole away from the fixing frame. Thin rods are fixedly connected to both sides of the supporting block 2, and the thin rods on both sides of the supporting block 2 are respectively fixedly connected to the connecting rod 3 on both sides, and the thin rods are made of flexible material. When the switch slides toward the side close to the fixing frame, the angle between the thin rods on both sides of the supporting block 2 gradually increases, and the supporting block 2 moves toward the outside of the mounting hole.

[0016] It is easy to understand that when the staff pushes the switch in the direction of the fixing bracket, the connecting rod 2 will drive the supporting block 1 to move away from the mounting hole. At this time, the connecting rod 3 on the connecting rod 2 will move together with the connecting rod 2. At this time, since the distance between the connecting rods 3 on both sides gradually increases, the supporting block 2 set in the mounting hole is moved toward the outside of the mounting hole by the pulling force of the thin rod and supports the mounting hole. Therefore, this design further improves the expansion effect of the expansion component on the mounting hole, so that the wiring harness terminal can be more easily inserted into the mounting hole, and the thin rod is a flexible material, which can play a buffering role when the supporting block moves, thereby avoiding the wear of the sealing plug when the supporting block moves, protecting the sealing plug, and increasing the service life of the sealing plug.

[0017] Preferably, the supporting block 1 and the supporting block 2 are both conical, and the distance between the supporting block 1 on both sides of the mounting hole and the distance between the supporting block 2 on both sides of the mounting hole gradually decrease toward the fixing frame. When the switch slides toward the side away from the fixing frame, the supporting block 1 and the supporting block 2 on the mounting hole on the side away from the fixing frame move closer to each other, and the distance between the supporting block 1 on both sides of the mounting hole and the distance between the supporting block 2 on both sides of the mounting hole are smaller than the diameter of the installation.

[0018] It is easy to understand that when the wiring harness terminal is installed and the male connector and the female connector are connected, the support block 1 and the support block 2 will follow the connecting rod 2 to move outside the mounting hole. In the future, when the staff needs to remove the wiring harness terminal and reinstall it, the sealing plug is made of elastic material and the mounting hole shrinks after losing the support of the wiring harness terminal and the support block. This makes it very difficult for the staff to operate the switch to control the support block 1 and the support block 2 to return to the mounting hole. Therefore, the design designs the support block 1 and the support block 2 as a cone. When the support block 1 and the support block 2 move toward the mounting hole, the top of the cone will first penetrate into the mounting hole. At this time, continue to move the support block 1 and the support block 2 to smoothly enter the mounting hole. Therefore, the design facilitates the installation of the wiring harness terminal during future inspection and maintenance by the staff, thereby improving work efficiency.

[0019] Preferably, an extrusion groove is provided on the female connector, and both sides of the extrusion groove are chamfered. When the male connector and the female connector are connected, the inner wall of the extrusion groove contacts the switch.

[0020] It is easy to understand that after the male connector and the female connector are connected, in the future use process, since the automotive wire end connector is installed on the car, the vibration and bumps generated by the car will act on the automotive wire end connector. At this time, the switch is vibrated and will drive the connecting rod 1 and the connecting rod to vibrate back and forth inside the mounting seat, which will cause the support block 1 and the support block 2 to rub the wiring harness and the sealing plug back and forth, thereby causing the wear of the wiring harness and the sealing plug to increase. Therefore, the design has an extrusion groove on the female connector. When the male connector and the female connector are connected, the switch will enter the extrusion groove and contact the inner wall of the extrusion groove. At this time, since the male connector and the female connector are locked by the buckle, the extrusion groove will press against the switch to fix the switch, thereby avoiding the wear of the wiring harness and the sealing plug caused by the shaking of the switch. Therefore, the design improves the service life of the automotive wire end connector.

[0021] Preferably, a sealing gasket is provided on the second connecting rod, and a rectangular block is also provided inside the mounting seat, and a fourth inclined surface is provided on the rectangular block. When the first connecting rod moves toward the mounting hole, the second control rod contacts the rectangular block, and the sealing gasket fits against the inner wall of the sliding hole.

[0022] It is easy to understand that when the connecting rod 2 follows the switch and moves toward the side away from the mounting hole, the connecting rod 2 slides on the sliding hole. When the wiring harness terminal is installed, there is a gap between the connecting rod 2 and the inner wall of the sliding hole. During the future use of the automotive wire end connector, liquid and various impurities will enter the mounting seat through the gap, and enter the automotive wire end connector through the gap between the mounting seat and the male connector, thereby causing the automotive wire end connector to short-circuit and corrode. Therefore, this design arranges a sealing gasket on the connecting rod 2. When the connecting rod 2 follows the switch and moves toward the side away from the mounting hole, the connecting rod will be squeezed by the rectangular block so that the sealing gasket fits against the inner wall of the sliding hole. At this time, liquid and impurities cannot enter the mounting seat, thereby ensuring the sealing of the mounting seat and improving the reliability of the automotive wire end connector.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention arranges an expansion component inside the mounting seat, and the expansion component can control the support block to move in the direction away from the mounting hole. During the movement of the support block, since the sealing plug is made of flexible material, the support block will squeeze the inner wall of the mounting hole. At this time, the inner wall of the mounting hole will expand outward due to the squeezing, and the wiring harness terminal can be smoothly inserted into the mounting hole. Due to the action of the support block, the pressure of the inner wall of the mounting hole on the wiring harness terminal is reduced, thereby avoiding the wiring harness terminal from scratching the inner wall of the mounting hole during installation. Therefore, the design saves the step of the staff using tools to support the mounting hole, and also avoids the wiring harness terminal from damaging the sealing plug during the installation process, which not only improves the work efficiency, but also improves the reliability of the automotive line terminal connector.

[0025] 2. The present invention arranges a control rod 2 inside the mounting seat. When the wiring harness terminal is installed, the switch is pushed in the direction away from the fixing frame. The switch will drive the control rod 2 to move together. Since the connecting rod 2 is slidingly connected to the connecting rod 1, the connecting rod 2 will move with the control rod 2. At this time, the support block on the connecting rod 2 will move with the connecting rod 2 and leave the mounting hole. This design allows the support block to move away from the mounting hole after the wiring harness terminal is installed, thereby preventing the support block from being clamped between the sealing plug and the wiring harness terminal, resulting in a gap between the inner wall of the mounting hole and the wiring harness terminal, and further causing the sealing effect of the sealing plug to decrease. Therefore, this design ensures the sealing effect of the sealing plug.

[0026] 3. The present invention further fixes connecting rod three on connecting rod two. When the staff pushes the switch in the direction of the fixing frame, connecting rod two will drive supporting block one to move in the direction away from the mounting hole. At this time, connecting rod three on connecting rod two will move together with connecting rod two. At this time, since the distance between connecting rods three on both sides gradually increases, supporting block two set in the mounting hole is moved toward the outside of the mounting hole by the pulling force of the thin rod and supports the mounting hole. Therefore, this design further improves the expansion effect of the expansion component on the mounting hole, so that the wiring harness terminal can be more easily inserted into the mounting hole.

The supporting block 10 is fixedly connected to the connecting rods 14. An inclined surface 15 is provided at one end of the slider 12 close to the control rod 11. The control rod 11 is provided with a chamfered angle. When the switch 9 slides toward the side close to the fixing frame 5, the slider 12 approaches the control rod 11, the control rod 11 contacts the inclined surface 15 and the control rod 11 slides on the inclined surface 15.

[0038] For further information, see Figures 1 to 8 , a second slider 16 is also provided inside the mounting seat 8, and the second slider 16 is fixedly connected to the switch 9, and an inclined surface 17 is provided at one end of the second slider 16 close to the control rod 11, and the control rod 11 is also provided with a chamfered angle. When the switch 9 slides toward the side away from the fixing frame 5, the second slider 16 approaches the control rod 11, and the control rod 11 contacts the inclined surface 17 and slides on the inclined surface 17. A sliding hole 18 is provided on the mounting seat 8, and the connecting rod 14 is slidably connected to the sliding hole 18. The connecting rod 14 is slidably connected to the connecting rod 13, and the mounting seat 8 is also provided inside. A control rod 2 19 is provided, and both ends of the control rod 2 19 are fixedly connected to the connecting rod 2 14 respectively. A rectangular hole 20 is opened on the switch 9. A rectangular rod 21 is fixedly connected to the control rod 2 19. The rectangular rod 21 is slidably connected in the rectangular hole 20. A slider 3 22 is also fixedly connected inside the mounting seat 8. An end of the slider 3 22 close to the control rod 2 19 is provided with an inclined surface 3 23. When the switch 9 slides toward the side close to the fixing frame 5, the slider 3 22 approaches the control rod 2 19, the control rod 2 19 contacts the inclined surface 3 23, and the control rod 2 19 slides on the inclined surface 3 23.

[0039] See also Figures 1 to 8, a connecting rod three 24 is also fixedly connected to the connecting rod two 14, and a supporting block two 25 is also provided on the inner wall of the mounting hole 4 away from the fixing frame 5. Thin rods 26 are fixedly connected to both sides of the supporting block two 25. The thin rods 26 on both sides of the supporting block two 25 are respectively fixedly connected to the connecting rod three 24 on both sides. The thin rods 26 are made of flexible material. When the switch 9 slides toward the side close to the fixing frame 5, the angle between the thin rods 26 on both sides of the supporting block two 25 gradually increases, and the supporting block two 25 moves toward the outside of the mounting hole 4. The supporting block one 10 and the supporting block two 25 are both conical, and the distance between the supporting block one 10 on both sides of the mounting hole 4 and the distance between the supporting block two 25 on both sides of the mounting hole 4 gradually decreases toward the fixing frame 5. When the switch 9 moves away from the fixing frame 5, the angle between the thin rods 26 on both sides of the supporting block two 25 gradually increases. When one side of the fixed frame 5 slides, the supporting block 10 and the supporting block 2 25 on the mounting hole 4 on the side away from the fixed frame 5 are close to each other, and the distance between the supporting block 10 on both sides of the mounting hole 4 and the distance between the supporting block 2 25 on both sides of the mounting hole 4 are less than the installation diameter. An extrusion groove 27 is provided on the female connector 2, and chamfers are made on both sides of the extrusion groove 27. When the male connector 1 and the female connector 2 are connected, the inner wall of the extrusion groove 27 contacts the switch 9, and a sealing gasket 28 is provided on the connecting rod 2 14. A rectangular block 29 is also provided inside the mounting seat 8, and a slope 4 30 is provided on the rectangular block 29. When the connecting rod 13 moves toward the side of the mounting hole 4, the control rod 2 19 contacts the rectangular block 29, and the sealing gasket 28 fits the inner wall of the sliding hole 18.

[0040] See also Figures 1 to 8When the staff assembles the wiring harness terminal 6, the staff pushes the switches 9 on both sides of the male connector 1 toward the side where the fixing frame 5 is located. At this time, the switch 9 moves and drives the slider 12 inside the mounting seat 8 to move. When the slider 12 moves a certain distance, the inclined surface 15 on the slider 12 contacts the control rod 11 inside the mounting seat 8. At this time, the inclined surface 15 applies pressure to the control rod 11 to move the control rod 11 toward the outside of the male connector 1. At this time, the connecting rod 13 fixedly connected to the control rod 11 and the connecting rod 2 14 fixedly connected to the connecting rod 13 move together with the control rod 11. At this time, the supporting block 10 on the connecting rod 2 14 will move together with the connecting rod 13. At this time, the supporting block 10 will press the inner wall of the mounting hole 4 When pressure is applied, the inner wall of the mounting hole 4 is subjected to pressure, and the mounting hole 4 begins to expand toward both sides. During the movement of the connecting rod 2 14, the connecting rod 3 24 on the connecting rod 2 14 will move along with the connecting rod 2 14. At this time, since the supporting block 2 25 in the mounting hole 4 is connected to the connecting rod 3 24 on both sides through the thin rods 26 on both sides, when the connecting rod 3 24 moves, the connecting rod 3 24 stretches the supporting block 2 25 on both sides and applies tension to the supporting block 2 25. At this time, the supporting block 2 25 will apply pressure to the inner wall of the mounting hole 4. After the inner wall of the mounting hole 4 is subjected to pressure, the mounting hole 4 begins to expand toward both sides. At this time, the mounting hole 4 is fully expanded all around, and the staff inserts the wiring harness terminal 6 into the mounting hole 4, and fixes the wiring harness terminal 6 to the fixing frame 5 from the other side.

[0041] See also Figures 1 to 8When the staff completes the assembly of the wiring harness terminal 6, the staff pushes the switch 9 in the direction away from the fixing frame 5. At this time, the switch 9 drives the slider 12 to move. The slider 12 moves a certain distance and then moves away from the control rod 11. At this time, the control rod 11 contacts the inclined surface 2 17 on the slider 2 16. At this time, the inclined surface 2 17 applies pressure to the control rod 11 to make the control rod 11 move toward the inside of the male connector 1. At this time, the connecting rod 13 fixedly connected to the control rod 11 and the connecting rod 2 14 fixedly connected to the connecting rod 13 move together with the control rod 11. At this time, the supporting block 10 on the connecting rod 2 14 will move together with the connecting rod 13. At this time, the connecting rod 3 24 moves together with the connecting rod 2 14. At this time, the supporting block 2 25 is no longer subjected to the pulling force of the thin rods 26 on both sides and begins to reset. At this time, the inner wall of the mounting hole 4 loses the pressure of the supporting block 10 and the supporting block 2 25, so that the mounting hole 4 begins to shrink. When the switch 9 moves At this time, since the control rod 219 and the switch 9 are connected to each other through the rectangular rod 21 and the rectangular hole 20, when the switch 9 moves, the control rod 219 moves with the switch 9. At this time, the control rod 219 drives the connecting rods 214 on both sides to move together. At this time, the connecting rod 214 drives the supporting block 10 and the supporting block 25 to move. At this time, the supporting block 10 and the supporting block 25 are away from the mounting hole 4. When the control rod 219 moves a certain distance and contacts the inclined surface 4 30 on the rectangular block 29, the rectangular block 29 applies pressure to the control rod 219, so that the sealing gasket 28 on the connecting rod 214 fits with the sliding hole 18. At this time, the supporting block 10 and the supporting block 25 are completely away from the mounting hole 4. At this time, the male connector 1 and the female connector 2 are connected to each other. At this time, the bayonet on the male connector 1 cooperates with the female connector 2 to fix the male connector 1 and the female connector 2. At this time, the switch 9 on the male connector 1 enters the pressing groove on the female connector 2 and contacts the inner wall of the pressing groove.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
