Description

Technical Field

[0001] This application relates to the field of automotive cable installation technology, and in particular to a wire harness connector protection structure and an automobile. Background Technology

[0002] Automobiles are mainly composed of engines, chassis, bodies, and electrical equipment. Automobile performance focuses on power, fuel economy, safety, and off-road capability. However, with technological advancements, automobiles are also developing towards electrification and intelligentization. Along with the development of electric and intelligent automobiles, the number of electrical and communication lines in vehicles is increasing, requiring timely industrial upgrades of wiring harnesses and communication connectors to provide products with higher reliability and a lifespan that meets the vehicle's overall lifespan.

[0003] There are numerous wiring harnesses inside a car used for signal transmission. These harnesses have connectors to connect multiple strands of wire together. However, the connectors themselves are not fixedly connected to the car frame, making them prone to movement. Currently, car manufacturers typically use cable ties or similar items to bind the connectors to the car frame during production. During daily driving, cars frequently vibrate, causing the cable ties to loosen and the connectors to fall off, which in turn leads to the wiring harnesses coming loose. This affects the functionality and lifespan of both the wiring harnesses and connectors. Therefore, it is necessary to improve the reliability of the fixing of automotive wiring harnesses and their connectors to reduce the risk of loosening and falling off. Utility Model Content

[0004] In view of this, this application aims to propose a wire harness connector protection structure to improve the protection effect and installation stability of wire harness connectors.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] A wire harness connector protection structure includes a mounting base, a cover plate, and a pressure plate disposed on the cover plate; the mounting base has a protective cavity formed inside, the protective cavity has an inlet for inserting a connector for the wire harness at the top of the mounting base, and the side wall of the mounting base has a through hole for the wire harness to pass through the protective cavity; the cover plate is installed on the mounting base to block the inlet, and as the cover plate is installed in place, the pressure plate can press the connector tightly into the protective cavity.

[0007] Furthermore, it also includes a fixing frame for fixing the mounting base to the base component; the fixing frame includes a fixing plate disposed on the side of the mounting base, and the fixing plate is provided with a mounting structure for connecting the base component.

[0008] Furthermore, the mounting structure includes fastening bolts that pass through the fixing plate, and a boss is formed at the through hole on the fixing plate for the fastening bolts to pass through; the head of the fastening bolt abuts against the boss.

[0009] Furthermore, the bottom of the fixing plate is flush with the bottom of the mounting base, and the fixing frame also includes a connecting plate connecting the fixing plate and the mounting base; the connecting plate includes an integrally connected lower plate and a side plate, the side plate being bent relative to the lower plate, the lower plate being connected to the top of the fixing plate, and the side plate being connected to the side of the mounting base.

[0010] Furthermore, the lower plate and the side plate are respectively fastened to the fixing plate and the mounting base by screws.

[0011] Furthermore, a supporting rib is provided between the lower plate and the side plate.

[0012] Furthermore, the top of the mounting base is provided with a sealing groove arranged around the inlet, and the cover plate is correspondingly provided with a sealing protrusion; as the cover plate is installed in place, the sealing protrusion and the sealing groove are sealed together.

[0013] Furthermore, the pressure plate is guided and disposed on the cover plate along the height direction of the mounting base, and an elastic element is provided between the pressure plate and the cover plate. The pressure plate is pressed against the connector under the elastic force of the elastic element.

[0014] Furthermore, the cover plate has a guide hole, the pressure plate is slidably disposed in the guide hole via a guide rod, and the elastic element includes a spring fitted on the guide rod.

[0015] Compared with related technologies, this application has the following advantages:

[0016] (1) The wire harness connector protection structure of this application provides a protective cavity on the mounting base and a cover plate with a pressure plate on the mounting base. This allows the wire harness connector to be firmly pressed and fixed in the protective cavity of the mounting base. After the mounting base is fixed to the vehicle body or other basic components, the reliability of the connector installation on the basic components is ensured. At the same time, the cover plate provides a closed space for the connector by blocking the entrance of the protective cavity, reducing the corrosion of the connector by moisture, dust and other substances, thereby improving the protection effect and installation stability of the wire harness connector.

[0017] (2) The mounting base is equipped with a fixing bracket, which facilitates the fixing plate set on the side of the mounting base to fix the mounting base on the base component. This provides good conditions for the setting of the protective cavity, wire hole and cover plate on the mounting base, and enables the mounting base to be installed conveniently and effectively on the base component.

[0018] (3) A through hole is provided on the fixing plate, and the fixing plate is fixed to the base component by fastening bolts. It has the advantages of simple structure, reliable connection performance and convenient installation and operation. By setting a boss at the through hole of the fixing plate, the structural strength of the through hole of the fixing plate can be effectively improved, and the final height of the head of the fastening bolt after tightening can also be raised, so as to avoid interference between the head of the fastening bolt and the connecting plate below, and improve the operation convenience when tightening the fastening bolt.

[0019] (4) The cross-section of the connecting plate is designed as an "L" shape, with the lower plate and side plates located at the two sides of the "L" respectively. This is suitable for the right-angle distribution of the side walls of the fixing plate and the mounting base, which can perfectly realize the reliable connection between the connecting plate and the mounting base and the fixing plate. The angle iron structure of the connecting plate itself can also ensure the structural reliability of the connecting plate itself.

[0020] (5) The lower plate and the fixed plate, as well as the side plate and the mounting base, are all fixedly connected by screws. This is similar to the installation method of fastening bolts, and has the same technical advantages of simple structure, reliable connection performance and easy installation operation.

[0021] (6) Setting support ribs between the lower plate and the side plate of the connecting plate can effectively improve the overall structural stability of the connecting plate.

[0022] (7) A sealing structure with sealing protrusions and sealing grooves is provided between the mounting base and the cover plate, which can effectively improve the sealing effect of the cover plate on the protective cavity, making the protective cavity a waterproof and dustproof sealed space, thereby further improving the protective effect of the wire harness connector protective structure on the connector.

[0023] (8) The pressure plate is set on the cover plate in a guideable and movable manner. The elastic element between the pressure plate and the cover plate provides the clamping force for the pressure plate to connect the plug. It can adapt to the clamping and fixing requirements of plugs of different thicknesses, thereby greatly improving the applicability and versatility of the wire harness connector protection structure.

[0024] (9) A guide structure with guide holes and guide rods is set between the pressure plate and the cover plate. The structure is simple and can improve the guiding effect. At the same time, the setting of the guide rod also provides good conditions for the spring to be sleeved. The two ends of the spring abut against the cover plate and the pressure plate respectively, forming a good elastic support between the two.

[0025] Another object of this application is to provide an automobile equipped with the wiring harness connector protection structure described in this application.

[0047] As is well known, automobiles and other equipment typically contain numerous wiring harnesses for signal transmission. These harnesses have connectors to link multiple wires together. However, these connectors are not fixedly attached to the vehicle body, equipment frame, or other basic components, making them prone to movement. Taking automobiles as an example, automakers currently use cable ties to bind connectors to the vehicle frame during production. During daily driving, vehicles frequently vibrate, causing these cable ties to loosen and leading to connector detachment. This, in turn, results in the wiring harness falling off, affecting the functionality and lifespan of both the harness and connectors. Therefore, it is necessary to improve the reliability of the securing of automotive wiring harnesses and their connectors to reduce the risk of loosening and detachment.

[0048] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new wire harness connector protection structure, which can improve the protection effect and installation stability of the wire harness connector.

[0049] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0050] The first aspect of this application provides a wire harness connector protection structure, which can be applied to the arrangement of electrical wire harnesses in automobiles and other types of equipment; an exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0051] Overall, the wire harness connector protection structure includes a mounting base 1, a cover plate 7, and a pressure plate 13 disposed on the cover plate 7. The mounting base 1 has a protective cavity 101 formed inside. The protective cavity 101 has an inlet 102 at the top for inserting the connector into the wire harness, and the side wall of the mounting base 1 has a through hole 11 for the wire harness to pass through the protective cavity 101. The cover plate 7 is installed on the mounting base 1 to seal the inlet 102, and as the cover plate 7 is installed in place, the pressure plate 13 can press the connector tightly into the protective cavity 101.

[0052] Based on the overall design concept described above, by setting a protective cavity 101 on the mounting base 1 and a cover plate 7 with a pressure plate 13 on the mounting base 1, the connector of the wire harness can be firmly pressed and fixed in the protective cavity 101 of the mounting base 1. After the mounting base 1 is fixed to the vehicle body or other basic components, the installation reliability of the connector on the basic components is ensured. At the same time, the cover plate 7 blocks the entrance 102 of the protective cavity 101, providing a closed space for the connector, reducing the corrosion of the connector by moisture, dust, etc., thereby improving the protection effect and installation stability of the wire harness connector.

[0053] It should be noted that, based on the above overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the mounting base 1 can be designed as circular or square, and can be directly screwed or glued to the base component, or fixed to the base component by the following fixing bracket. The specific arrangement sequence and assembly method of the mounting base 1 on the base component and the cover plate 7 on the mounting base 1 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible design can be made by referring to mature setting methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the above various combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above various specific combinations and variations, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this application.

[0054] There are various structural options available for the specific installation and fixing of the cover plate 7 on the mounting base 1. For example, the cover plate 7 can be fixed to the inlet 102 position at the top of the mounting base 1 using a plug-in or snap-fit ​​method. In this embodiment, the cover plate 7 is provided with a locking hole 100, and a locking pin 10 is inserted into the top of the side wall of the mounting base 1. After the cover plate 7 is fastened onto the mounting base 1 and installed in place, the locking pin 10 can be inserted into the corresponding locking hole 100, thereby reliably locking and fixing the cover plate 7 to the mounting base 1.

[0055] Continue as Figure 3 and combined Figure 4 , Figure 5 As shown, in some preferred exemplary embodiments, the top of the mounting base 1 in this embodiment is provided with a sealing groove 9 arranged around the inlet 102, and a corresponding sealing protrusion 8 is provided on the cover plate 7. As the cover plate 7 is installed in place, the sealing protrusion 8 and the sealing groove 9 are sealed together. The sealing structure of the sealing protrusion 8 and the sealing groove 9 between the mounting base 1 and the cover plate 7 can effectively improve the sealing effect of the cover plate 7 on the protective cavity 101, making the protective cavity 101 a waterproof and dustproof sealed space (the wire hole 11 through which the wire harness passes can be sealed with sealing glue), thereby further improving the protective effect of the wire harness connector protection structure on the connector.

[0056] Based on the setting of the sealing protrusion 8 on the cover plate 7, a locking hole 100 can be set at each of the four corners of the sealing protrusion 8, and four locking pins 10 can be inserted into the top of the side wall of the mounting base 1 accordingly, so as to lock and fix the four corners of the cover plate 7 to the mounting base 1, thereby improving the firmness of the cover plate 7 sealing the mounting base 1.

[0057] like Figure 5 , Figure 6 and Figure 7 As shown, in some preferred exemplary embodiments, the pressure plate 13 of this embodiment is guided and disposed on the cover plate 7 along the height direction of the mounting base 1, and an elastic element is provided between the pressure plate 13 and the cover plate 7. After the cover plate 7 is installed in place, the pressure plate 13 is pressed against the connector under the elastic force of the elastic element. The pressure plate 13 is disposed on the cover plate 7 in a guideable and movable manner. The elastic element between the pressure plate 13 and the cover plate 7 provides the clamping force of the pressure plate 13 on the connector, which can adapt to the clamping and fixing requirements of connectors of different thicknesses, thereby greatly improving the applicability and versatility of the wire harness connector protection structure.

[0058] Regarding the guiding arrangement of the pressure plate 13 on the cover plate 7, there are naturally many different structural solutions to choose from; for example, a guide groove structure can be provided. In this embodiment, such as... Figure 6 and Figure 7 As shown, a guide hole 700 is provided on the cover plate 7, and the pressure plate 13 is slidably disposed in the guide hole 700 via the guide rod 12. In this case, preferably, the elastic element includes a spring 14 fitted on the guide rod 12. The guide structure with the guide hole 700 and the guide rod 12 between the pressure plate 13 and the cover plate 7 is simple in structure and can improve the guiding effect. At the same time, the setting of the guide rod 12 also provides good conditions for the fitting of the spring 14. The two ends of the spring 14 abut against the cover plate 7 and the pressure plate 13 respectively, forming a good elastic support between the two.

[0059] The number of guide holes 700 and guide rods 12 can be flexibly selected. In this embodiment, the cover plate 7 has four guide holes 700, with two guide holes 700 forming a group, corresponding to two guide rods 12. The top ends of the two guide rods 12 extend to the top of the cover plate 7 and are connected as one unit by a pull handle 15. This arrangement facilitates lifting the pressure plate 13 by pulling the pull handle 15, temporarily releasing the clamping state of the connector, so as to adjust the position of the connector in the protective cavity 101. For the case where two groups of guide holes 700 provide four guide rods 12, it is preferable to install a spring 14 on each guide rod 12. The balanced arrangement of the four springs 14 can improve the balance of force on the pressure plate 13.

[0060] Continue as Figure 1 and combined Figure 8As shown, in some preferred exemplary embodiments, the wire harness connector protection structure of this embodiment further includes a fixing bracket for fixing the mounting base 1 to the base component; the fixing bracket can of course have various structural forms to choose from; in this embodiment, the fixing bracket includes a fixing plate 2 provided on the side of the mounting base 1, and the fixing plate 2 is provided with an installation structure for connecting to the base component. Configuring the fixing bracket for the mounting base 1 facilitates the fixing plate 2 provided on the side of the mounting base 1 to achieve the fixed installation of the mounting base 1 on the base component, provides favorable conditions for the setting of the protective cavity 101, the wire hole 11, and the cover plate 7 on the mounting base 1, and enables convenient and effective installation of the mounting base 1 on the base component. In specific implementation, wire holes 11 can be opened on the left and right sides of the mounting base 1 respectively, allowing the wire harnesses on both sides of the connector to pass through the protective cavity 101 respectively; a set of fixing brackets can be provided on the front and rear sides of the mounting base 1, so that the front and rear sides of the mounting base 1 can be firmly connected to the base component by two fixing plates 2 respectively, achieving reliable fixed installation of the entire wire harness connector protection structure on the base component.

[0061] Specifically, in some preferred exemplary embodiments, the installation structure of this embodiment includes fastening bolts 6 passing through the fixing plate 2, and a boss 5 is formed at the through hole on the fixing plate 2 for the fastening bolts 6 to pass through. This boss 5 should naturally be located on the top of the fixing plate 2, i.e., the side facing away from the base component. When the fixing plate 2 is fixed to the base component using the fastening bolts 6, the head of the fastening bolts 6 abuts against the boss 5. Providing through holes on the fixing plate 2 and using fastening bolts 6 to fix the fixing plate 2 to the base component has advantages such as simple structure, reliable connection performance, and ease of installation. By providing a boss 5 at the through hole of the fixing plate 2, not only can the structural strength of the through hole location of the fixing plate 2 be effectively improved, but the final height of the head of the fastening bolt 6 after tightening can also be increased, avoiding interference between the head of the fastening bolt 6 and the connecting plate 3 described below, thus improving the ease of operation when tightening the fastening bolts 6.

[0062] Based on the above configuration, preferably, the fixing frame in this embodiment further includes a connecting plate 3 connecting the fixing plate 2 and the mounting base 1. The bottom of the fixing plate 2 is flush with the bottom of the mounting base 1, and the fixing plate 2 is fixedly connected to the mounting base 1 via the connecting plate 3. The connecting plate 3 includes an integrally connected lower plate 301 and a side plate 302. The side plate 302 is bent relative to the lower plate 301. The lower plate 301 is connected to the top of the fixing plate 2, and the side plate 302 is connected to the side of the mounting base 1. Designing the cross-section of the connecting plate 3 as an "L" shape, with the lower plate 301 and side plate 302 located at the two sides of the "L," is suitable for the right-angle distribution of the side walls of the fixing plate 2 and the mounting base 1, perfectly achieving a reliable connection between the connecting plate 3 and the mounting base 1. The angle iron structure of the connecting plate 3 itself also ensures the structural reliability of the connecting plate 3.

[0063] Regarding the connection method between the connecting plate 3, the mounting base 1, and the fixing plate 2, there are naturally many different structural solutions to choose from; for example, they can be fixed by bonding or welding. In this embodiment, it is still as follows... Figure 8 As shown, the lower plate 301 and the side plate 302 are respectively screwed to the fixing plate 2 and the mounting base 1 by screws 300. To improve the connection firmness, a screw 300 is passed through each of the two corners of the lower plate 301 and screwed to the fixing plate 2; similarly, a screw 300 is also passed through each of the two corners of the side plate 302 and screwed to the side wall of the mounting base 1. The lower plate 301 and the fixing plate 2, as well as the side plate 302 and the mounting base 1, are all fixedly installed by screws 300, similar to the installation method of the fastening bolts 6, which also has the technical advantages of simple structure, reliable connection performance and convenient installation operation.

[0064] In addition, support ribs 4 can be provided between the lower plate 301 and the side plate 302. Providing support ribs 4 between the lower plate 301 and the side plate 302 of the connecting plate 3 can effectively improve the overall structural stability of the connecting plate 3. Specifically, two support ribs 4 are provided at intervals on each connecting plate 3. The support ribs 4 are set as right-angled triangles or right-angled trapezoids, and the bottom and right-angled sides of the support ribs 4 are welded and fixed to the lower plate 301 and the side plate 302, respectively.

[0065] Based on the above exemplary embodiments, as a preferred combination of the exemplary solutions, refer to Figures 1 to 8 As shown, when implementing the wire harness connector protection structure of this application, the following overall implementation scheme can be referred to:

[0066] The entire wiring harness connector protection structure includes a mounting base 1, a fixing plate 2, a connecting plate 3, and a cover plate 7. The mounting base 1 has fixing plates 2 installed on both sides of its bottom. Connecting plates 3 are installed on the fixing plates 2, and supporting ribs 4 are provided on the connecting plates 3. Two sets of bosses 5 are symmetrically installed on the fixing plates 2, with through holes for fastening bolts 6, thus securing the fixing plates 2 to the vehicle body or other basic components.

[0067] A cover plate 7 is installed on the top of the mounting base 1. A sealing protrusion 8 is provided at the bottom edge of the cover plate 7. A sealing groove 9 is provided on the top of the mounting base 1, surrounding the entrance 102 of the protective cavity 101. Four sets of locking pins 10 are symmetrically installed on both sides of the top of the mounting base 1. Multiple sets of wire holes 11 are provided on both sides of the mounting base 1. When the two sets of fixing brackets are respectively located on the front and rear sides of the mounting base 1, the multiple sets of wire holes 11 and locking pins 10 are preferably located on the side walls of the left and right sides of the mounting base 1. Four sets of guide holes 700 are symmetrically provided on the top of the cover plate 7, in which guide rods 12 are installed. The bottom of the guide rods 12 is fixed to the pressure plate 13. A pull handle 15 is provided between the top ends of two guide rods 12 in the same set. A spring 14 is sleeved on the part of the guide rod 12 located between the cover plate 7 and the pressure plate 13.

[0068] Meanwhile, the mounting base 1 has a protective cavity 101 inside, the size of which is adapted to the size of the connector on the automotive wiring harness. The connector can be installed in this cavity, and the wiring harness connected to the connector can be passed through the wiring holes 11 on both sides of the mounting base 1. The fixing plate 2 is fixedly installed on both sides of the mounting base 1. The lower plate 301 of the connecting plate 3 is fixedly connected to the fixing plate 2 by screws 300, and the side plate 302 of the connecting plate 3 is fixedly connected to the side wall of the mounting base 1 by screws 300. Thus, the connecting plate 3 can improve the connection strength between the fixing plate 2 and the mounting base 1. Preferably, the connecting plate 3 has two sets of symmetrical support ribs 4, which are designed as right-angled trapezoidal structures. The support ribs 4 are fixedly connected to the connecting plate 3. The two sets of support ribs 4 can increase the strength of the connecting plate 3 itself, further increasing the installation stability of the fixing plate 2.

[0069] Preferably, the fixing plate 2 has two sets of symmetrical through holes. For each through hole, a boss 5 is formed at its top, and the through hole is formed on the boss 5. The through hole on the boss 5 and the fastening bolt 6 are provided with a matching thread structure. The top of the fastening bolt 6 is set with a hexagonal head structure so that the operator can rotate it with a tool. This allows the fastening bolt 6 to move axially along the through hole under the action of the thread thrust, so that the fastening bolt 6 can be screwed into the fixing hole opened in the base component such as the car body. The four sets of fastening bolts 6 can realize the overall fixed installation of this wire harness connector protection structure on the base component.

[0070] Preferably, the size of the cover plate 7 is adapted to the size of the mounting base 1, the side of the cover plate 7 is flush with the side of the mounting base 1, the sealing protrusion 8 is adapted to the sealing groove 9, and both are set as rectangular ring structures. The sealing protrusion 8 is inserted into the sealing groove 9, and the locking pin 10 is installed in the locking holes opened on the top of the left and right sides of the mounting base 1. The locking pin 10 is inserted into the locking hole 100 opened on the sealing protrusion 8, and then the sealing protrusion 8 is fixed and locked in the sealing groove 9 by four sets of locking pins 10, thereby realizing the fixed installation of the cover plate 7 on the top of the mounting base 1, so that the protective cavity 101 inside the mounting base 1 is a closed device, thereby playing a waterproof role and protecting the connectors inside from water, dust and other pollution and corrosion.

[0071] Preferably, the top of the guide rod 12 is flush with the top of the cover plate 7, the size of the pressure plate 13 is the same as the internal dimensions of the cover plate 7 (length and width), the spring 14 is located inside the cover plate 7, the bottom of the spring 14 is fixedly connected to the top of the pressure plate 13, and the top of the spring 14 is fixedly connected to the bottom of the inside of the cover plate 7. The four sets of springs 14 can make the pressure plate 13 press down against the connector inside the mounting base 1 under the action of elastic force. The bottom of the pressure plate 13 can also be provided with a soft pad structure to prevent the connector from being crushed or damaged.

[0072] Preferably, the diameter of the handle 15 is the same as the diameter of the guide rod 12. The handle 15 is located on the top of the cover plate 7. The handle 15 and the guide rod 12 are fixedly connected. The four guide rods 12 can be pulled upward by the two sets of handles 15, thereby causing the pressure plate 13 to disengage from the connector and thus contact the fixing of the connector. The spring 14 is compressed in this process, and the spring 14 can drive the pressure plate 13 to return downward.

[0073] In the actual manufacturing process, standard parts such as fastening bolts 6 and screws 300 can be purchased directly from the market, or they can be customized according to the technical parameters determined by the instruction manual and the attached drawings. The specific connection methods of each part can also adopt mature methods such as bolts, rivets, and welding from relevant technologies.

[0074] In summary, the wiring harness connector protection structure of this embodiment, by providing a protective cavity 101 on the mounting base 1 and a cover plate 7 with a pressure plate 13 on the mounting base 1, can firmly press and fix the wiring harness connectors within the protective cavity 101 of the mounting base 1. After the mounting base 1 is fixed to the vehicle body or other basic components, the reliability of the connector installation on the basic components is ensured. At the same time, the cover plate 7's sealing of the entrance 102 of the protective cavity 101 provides a closed space for the connectors, reducing the erosion of the connectors by moisture, dust, etc., thereby improving the protective effect and installation stability of the wiring harness connectors.

[0075] An embodiment of the second aspect of this application provides a car equipped with the wiring harness connector protection structure provided in Embodiment 1.

[0076] By equipping the vehicle with the wiring harness connector protection structure of this application, the installation, fixation, and protection of the wiring harness connectors can be effectively achieved. A protective cavity 101 is provided within the mounting base 1, and the size of the protective cavity 101 is adapted to the size of the connector on the vehicle's wiring harness, allowing the connector to be placed inside the protective cavity 101. The wiring harness connected to the connector can be passed through the wire holes 11 on both sides of the mounting base 1 from the outside into the protective cavity 101, ensuring the normal connection function of the connector. A cover plate 7 is installed on the top of the mounting base 1, which can close the protective cavity 101 of the mounting base 1. A pressure plate 13 is installed inside the cover plate 7, which can limit and fix the connector in the mounting base 1, ensuring the connector is stably installed in the mounting base 1. The mounting base 1 can be fixedly connected to the vehicle frame or other basic components through four sets of fastening bolts 6 on both sides, thereby achieving the fixed installation of the connector. Compared with the method of binding with cable ties, this method has stronger stability.

[0077] Meanwhile, by providing a sealing protrusion 8 at the bottom of the cover plate 7 and a corresponding sealing groove 9 at the top of the mounting base 1, the sealing protrusion 8 and the sealing groove 9 work together to greatly improve the sealing effect of the protective cavity 101. The mounting base 1 and the cover plate 7 are locked and fixed by four locking pins 10, thereby achieving the fixed installation of the cover plate 7 on the top of the mounting base 1. This ensures that the protective cavity 101 inside the mounting base 1 is in a well-sealed state, thus playing a waterproof role and protecting the connectors inside from the erosion of rainwater, dust, etc.
