Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to an automobile EMS rubber protective device and an installation method thereof. Background Art

[0002] The controller connector ends in the engine compartment must be arranged vertically to prevent water from seeping in and accumulating at the wire outlet holes of the connectors for a long time. Over time, there is a risk that water will seep into the terminals from the sealing rings, causing short circuits and fires. However, when the space in the engine compartment is limited, the EMS (engine management system) connector ends sometimes cannot meet the vertical arrangement requirements and can only be arranged horizontally, which can easily lead to water or dust entering the EMS interface.

[0003] At present, automobile engine wiring harness sheaths have appeared. When applied to EMS connectors, the sheath is installed on the outside of the connector to cover the connection position between the connector end and the wiring harness to protect the EMS connector. At the same time, it plays the role of waterproofing and dustproofing, thereby ensuring the reliability of the EMS connector.

[0004] However, EMS has two interfaces. According to the power supply and control functions, one interface is connected to the connector on the engine wiring harness, and the other interface is connected to the connector on the cabin wiring harness. This requires two processes: subassembly at the supplier and assembly at the main engine factory's assembly workshop. The existing wiring harness sheaths are mostly closed protective structures, which are difficult to remove after installation. For vehicles with horizontally arranged EMS interfaces, the existing wiring harness sheaths are difficult to apply to the situation of multiple EMS assembly processes, and the convenience of assembly, maintenance and disassembly is poor. Summary of the invention

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing engine harness sheath is difficult to remove after installation when applied to EMS, is difficult to apply to the situation of multiple assembly processes of EMS, and is not convenient for assembly, maintenance and disassembly, the present invention provides an automobile EMS rubber protective device.

[0006] The technical solution of the present invention is as follows: The present invention provides an automotive EMS rubber protective device, comprising a cover body for covering an EMS connector, the cover body having an opening at the bottom, one end of the cover body being fixedly connected with a first outlet connection sleeve, the other end of the cover body being fixedly connected with a second outlet connection sleeve, the first outlet connection sleeve and the second outlet connection sleeve both being C-shaped tube structures with an opening at the bottom, the first outlet connection sleeve and the second outlet connection sleeve both being communicated with the inside of the cover body, the first outlet connection sleeve being used for being sleeved on a cabin wiring harness, the second outlet connection sleeve being used for being sleeved on an engine wiring harness, a binding assembly being fixedly provided on the second outlet connection sleeve, the EMS connector being protected from external environmental factors such as dust and moisture by the cover body, ensuring the electrical performance of the connector being stable, and the C The outlet connector sleeve of the tube structure is convenient for connection with the cabin wiring harness and the engine wiring harness, which can not only realize effective protection of the wiring harness, but also adapt to the multiple assembly processes of the EMS. There is no need to remove and reinstall the protective device (specifically the cover body and the first outlet connector sleeve) in different assembly processes. It is easy to install and simple to operate, which effectively improves the assembly efficiency and is also convenient for subsequent disassembly, assembly and maintenance.

[0007] Preferably, a first opening groove penetrating through the bottom side wall is axially opened on the bottom side wall of the first outlet connecting sleeve and the second outlet connecting sleeve. During the assembly process, there is no need to insert the wiring harness from one end of the connecting sleeve with difficulty, and the wiring harness only needs to be slid into the bottom opening groove. For the complex wiring environment of the automobile engine compartment, it greatly saves assembly time and labor costs, improves work efficiency, and when the wiring harness is inspected or replaced at a later stage, the wiring harness can be conveniently and quickly removed from the opening groove, thereby enhancing the maintainability of the protective device.

[0008] Preferably, a rib is fixedly provided on the circumferential side of one end of the first outlet connecting sleeve away from the cover body, the outer diameter of the rib is larger than the diameter of the first outlet connecting sleeve, and a binding area is formed between the rib and the cover body. The setting of the rib effectively prevents the wiring harness from escaping from the first outlet connecting sleeve, thereby ensuring the connection stability between the wiring harness and the first outlet connecting sleeve.

[0009] Preferably, the binding assembly includes a first fixing column, a second fixing column and a connecting belt fixedly arranged on the outer wall of the second outlet connecting sleeve, the first fixing column and the second fixing column are relatively distributed on both sides of the bottom opening of the second outlet connecting sleeve, the fixed end of the connecting belt is located below the first fixing column / the second fixing column, and a plurality of connecting holes are spaced apart on the connecting belt along its length direction. The staff can select appropriate connecting holes to adjust the binding tightness of the connecting belt according to the actual thickness of the engine wiring harness, thereby ensuring the tight fixation between the second outlet connecting sleeve and the engine wiring harness, without the need for additional structural fixation such as cable ties, thereby facilitating operation, having better adaptability and flexibility, and improving the protection effect of the protective device on the engine wiring harness.

[0010] Preferably, the first fixing column and the second fixing column are both arranged obliquely downward, so that the connecting belt can generate a downward pulling force component when tying the wiring harness. This pulling force can make the engine wiring harness better fit on the second outlet connecting sleeve, further reduce the shaking space of the wiring harness, and enhance the stability of the wiring harness in the connecting sleeve. Even if the car encounters bumpy road conditions during driving, the oblique downward pulling force can help the wiring harness maintain a relatively fixed position, preventing the first fixing column and the second fixing column from escaping from the connecting hole on the connecting belt, thereby improving the reliability of the protective device.

[0011] Preferably, the first outlet connecting sleeve and the second outlet connecting sleeve are both arranged obliquely downward. The obliquely downward outlet connecting sleeve conforms to the natural drooping trend of the wiring harness in the engine compartment of the automobile, making the arrangement of the wiring harness in the connecting sleeve smoother, reducing the internal stress of the wiring harness caused by bending or twisting, and reducing the risk of damage to the wiring harness. At the same time, when rainwater or other liquids enter the engine compartment, the obliquely downward connecting sleeve can guide the liquid to flow naturally, preventing water from entering the connection position of the wire and the EMS connector along the side wall of the connecting sleeve and the first opening groove, thereby achieving a better waterproof effect.

[0012] Preferably, the Shore hardness of the protective device is 60±5°, so that the rubber protective device has a certain flexibility and good wear resistance and impact resistance. The flexibility enables it to adapt to slight deformation of components caused by factors such as vibration and temperature changes in the complex environment of the automobile engine compartment without being easily broken or damaged, thereby effectively protecting the internal EMS connector; the wear resistance ensures that the surface of the protective device is not easily worn during long-term contact and friction with the wiring harness and other components, thereby extending its service life; the impact resistance can reduce the impact force on the internal connector when the vehicle is subjected to a slight collision or bump, and at the same time ensure that the protective device connecting belt is easy to be connected, ensuring that it fits reliably and is not easy to fall off from the first fixing column and the second fixing column.

[0013] Preferably, a second vertical opening groove is respectively provided on the side walls at both ends of the cover body, and the second opening groove is located directly below the first outlet connecting sleeve and the second outlet connecting sleeve on the corresponding ends of the cover body. The second opening groove provides additional space for the transition of the wiring harness between the connecting sleeve and the cover body, which is convenient for operators to organize and adjust the wiring harness during installation, ensuring that the wiring harness can smoothly enter the cover body from the connecting sleeve and avoid bending or jamming of the wiring harness at the connection position. In subsequent maintenance and inspection work, maintenance personnel can also more intuitively check the connection status of the wiring harness and the connector through the second opening groove, quickly discover and solve potential problems, and improve the maintainability and troubleshooting efficiency of the protective device.

[0014] Preferably, a rib is fixedly provided on the circumferential side of one end of the second outlet connecting sleeve away from the cover body, so as to facilitate the use of a binding structure such as PVC tape or cable tie to wrap around and fix it on the second outlet connecting sleeve, thereby achieving a fixed connection between the second outlet connecting sleeve and the engine wiring harness trunk, to assist in the bundling and fixation of the connecting belt, further improve the firmness of the installation, and complete the assembly in the main assembly workshop of the OEM.

[0015] The present invention provides a method for installing an automotive EMS rubber protective device, which is specifically as follows: When subassembling at the supplier's place, one end of the EMS connector is connected to the cabin wiring harness wire, and then the cover body is buckled on the EMS connector, so that the cabin wiring harness wire passes through the first opening slot into the first outlet connection sleeve, and the first outlet connection sleeve is fixedly connected to the cabin wiring harness trunk by using a binding structure; the cabin wiring harness is reliably connected to a part of the protective device at the supplier's place, which can reduce the assembly process and time in the main engine factory assembly workshop, avoid assembly quality problems caused by excessive workload in the assembly workshop, and at the same time, ensure that the cabin wiring harness and the protective device are firmly and accurately connected, which is convenient for subsequent assembly work; During assembly in the main engine plant's final assembly workshop, the other end of the EMS connector is connected to the engine wiring harness, and the second outlet connection sleeve is set on the engine wiring harness trunk through the first open groove at its bottom. The second outlet connection sleeve is fixedly connected to the engine wiring harness trunk using its own binding assembly, and fixed using the first open groove of the second outlet connection sleeve and the built-in binding assembly. The operation is simple and quick, and the connection between the engine wiring harness and the protective device can be quickly completed, thereby improving the production efficiency of the final assembly workshop. The standardized assembly method can effectively reduce problems such as loose fixation of the wiring harness due to differences in manual operations.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are: 1. The cover body protects the EMS connector from external environmental factors to ensure the electrical performance of the connector is stable. The C-tube structure of the outlet connector is convenient for connection with the cabin wiring harness and the engine wiring harness, which can not only achieve effective protection of the wiring harness, but also adapt to the multiple assembly processes of the EMS. There is no need to remove the protective device (specifically the cover body and the first outlet connector) and perform secondary installation operations in different assembly processes. It is easy to install and simple to operate, which effectively improves the assembly efficiency and is also convenient for subsequent disassembly, assembly and maintenance.

[0017] 2. For the setting of the binding assembly, the staff can select the appropriate connection hole to adjust the binding tightness of the connecting belt according to the actual thickness of the engine wiring harness, so as to ensure the tight fixation between the second outlet connecting sleeve and the engine wiring harness. There is no need to use additional structures such as cable ties to fix them, which facilitates the operation, has better adaptability and flexibility, and improves the protection effect of the protective device on the engine wiring harness.

[0018] 3. The first fixing column and the second fixing column are both arranged obliquely downward, so that the connecting belt can generate a downward pulling force component when tying the wiring harness. This pulling force can make the engine wiring harness fit better on the second outlet connecting sleeve, further reduce the shaking space of the wiring harness, and enhance the stability of the wiring harness in the connecting sleeve. Even if the car encounters bumpy road conditions during driving, the oblique downward pulling force can help the wiring harness maintain a relatively fixed position, preventing the first fixing column and the second fixing column from escaping from the connecting hole on the connecting belt, thereby improving the reliability of the protective device.

[0019] 4. The first outlet connector sleeve and the second outlet connector sleeve are both arranged obliquely downward. The oblique downward outlet connector sleeve conforms to the natural drooping trend of the wiring harness in the engine compartment of the automobile, making the arrangement of the wiring harness in the connector sleeve smoother, reducing the internal stress of the wiring harness caused by bending or twisting, and reducing the risk of damage to the wiring harness. At the same time, when rain or other liquids enter the engine compartment, the oblique downward connector sleeve can guide the liquid to flow naturally, preventing water from entering the connection position of the wire and the EMS connector along the side wall of the connector sleeve and the first opening groove, thereby playing a better waterproof role.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] Example 1 In a typical embodiment of the present invention, Figure 1-Figure 4 As shown, an automotive EMS rubber protective device is proposed, comprising: a cover body 1, a first outlet connection sleeve 2 and a second outlet connection sleeve 3, the cover body 1, the first outlet connection sleeve 2 and the second outlet connection sleeve 3 are all made of rubber material, the cover body 1 is used to buckle on the outside of the EMS connector to cover and protect the EMS connector, one end of the cover body 1 is fixedly connected to the first outlet connection sleeve 2, and the other end of the cover body 1 is fixedly connected to the second outlet connection sleeve 3, the first outlet connection sleeve 2 and the second outlet connection sleeve 3 are both connected to the inside of the cover body 1, the first outlet connection sleeve 2 is used for the wires of the cabin wiring harness to pass through and connect with the EMS connector to complete the subassembly at the supplier, and the second outlet connection sleeve 3 is used to be sleeved on the trunk of the engine wiring harness when assembling in the main assembly workshop of the main engine factory to cover the connection position between the engine wiring harness and the EMS connector.

[0024] like Figure 2 As shown, the cover body 1 is a bottom opening structure, and the cover body 1 is hollow inside. The shape of the inner cavity of the cover body 1 matches the shape of the EMS connector, so that the cover body 1 can be buckled onto the EMS connector from above, and the EMS connector can be completely covered and protected by the cover body 1. Chamfers are provided at the internal corners of the cover body 1 to reduce stress concentration.

[0025] like Figure 2 and Figure 4As shown, the first outlet connection sleeve 2 is a C-shaped tube structure with an opening at the bottom. Specifically, the first outlet connection sleeve 2 is hollow inside, and a first opening groove 12 penetrating the bottom side wall is provided on the bottom side wall of the first outlet connection sleeve 2 along its axial direction. The first outlet connection sleeve 2 is open at one end away from the cover body 1 and a retaining edge 11 is fixedly provided on the periphery of the end. The outer diameter of the retaining edge 11 is larger than the diameter of the first outlet connection sleeve 2. The provision of the first opening groove 12 facilitates the insertion of the wires of the cabin wiring harness, and there is no need to remove the protective device as a whole. The wires can directly pass through the side wall of the first outlet connection sleeve 2 from the first opening groove 12 at the bottom. And enter the first outlet connection sleeve 2, so as to use the first outlet connection sleeve 2 to cover and protect the wires of the cabin wiring harness, and cooperate with the use of the cover body 1 to protect the connection position between the EMS connector end and the cabin wiring harness wires, and play a waterproof and dustproof role; since the first outlet connection sleeve 2 is made of rubber material, the setting of the retaining edge 11 cooperates with the outer wall of the cover body 1 to form a binding area, which is convenient for using PVC tape or cable tie and other binding structures to wrap and fix on the first outlet connection sleeve 2, thereby realizing the fixed connection between the first outlet connection sleeve 2 and the cabin wiring harness trunk, so as to complete the subpackaging at the supplier.

[0026] like Figure 4 As shown, the first outlet connection sleeve 2 is arranged obliquely downward, and the axis of the first outlet connection sleeve 2 and the horizontal axis of the cover body 1 have a downward angle, which can not only adapt to the direction of the cabin wiring harness wires, but also guide the water to flow downward without gathering at the first outlet connection sleeve 2, avoiding water from entering the connection position of the wire and the EMS connector along the side wall of the first outlet connection sleeve 2 and the first opening groove 12, thereby achieving a better waterproof effect.

[0027] like Figure 3 As shown, the second outlet connection sleeve 3 is also a C-shaped tube structure with an opening at the bottom. Specifically, the second outlet connection sleeve 3 is hollow inside, and a first open groove 12 penetrating the bottom side wall is opened on the bottom side wall of the second outlet connection sleeve 3 along its axial direction. The second outlet connection sleeve 3 is open at one end away from the cover body 1. The setting of the first open groove 12 makes it easy to set the second outlet connection sleeve 3 on the engine wiring harness trunk without removing the protective device as a whole. The engine wiring harness trunk can directly pass through the side wall of the second outlet connection sleeve 3 from the first open groove 12 at the bottom and enter the second outlet connection sleeve 3, so that the second outlet connection sleeve 3 is used to cover and protect the engine wiring harness trunk, and cooperate with the use of the cover body 1 to protect the connection position between the EMS connector end and the engine wiring harness trunk, and play a waterproof and dustproof role. A binding assembly is fixedly provided on the outer wall of the second outlet connecting sleeve 3, and the binding assembly includes a first fixing column 4, a second fixing column 5 and a connecting belt 6 fixedly provided on the outer wall of the second outlet connecting sleeve 3, the first fixing column 4 and the second fixing column 5 are relatively distributed on both sides of the first opening groove 12, and the first fixing column 4 and the second fixing column 5 are both close to the first opening groove 12 at the bottom of the second outlet connecting sleeve 3, one end of the connecting belt 6 is fixedly connected to the outer wall of the second outlet connecting sleeve 3 and is located below the first fixing column 4 / the second fixing column 5, and a plurality of connecting holes are spaced apart on the connecting belt 6 along its length direction. In actual use, the free end of the connecting belt 6 is wrapped around from the bottom to the top of the second outlet connecting sleeve 3, and is respectively connected to the first fixing column 4 and the second fixing column 5, thereby realizing the bundling of the second outlet connecting sleeve 3, so as to fix the second outlet connecting sleeve 3 to the engine wiring harness trunk.

[0028] In this embodiment, the fixed end of the connecting belt 6 is fixedly arranged below the second fixing column 5, and the connecting belt 6 is provided with a first connecting hole 7, a second connecting hole 8, a third connecting hole 9 and a fourth connecting hole 10, wherein the first connecting hole 7 and the second connecting hole 8 are close to the fixed end of the connecting belt 6, and the third connecting hole 9 and the fourth connecting hole 10 are close to the free end of the connecting belt 6. Therefore, during actual installation, after the free end of the connecting belt 6 is wrapped around the bottom to the top of the second outlet connecting sleeve 3, the first connecting hole 7 / the second connecting hole 8 is connected to the first fixing column 4, and the third connecting hole 9 / the fourth connecting hole 10 is connected to the second fixing column 5, so as to realize the firm installation of the connecting belt 6. The setting of several connecting holes can adapt to the bundling requirements of wire harnesses of different diameters.

[0029] It is understandable that the number and spacing of the connection holes on the connection belt 6 are set according to actual design requirements, and no excessive restrictions are made here.

[0030] In order to improve the connection firmness, the first fixing column 4 and the second fixing column 5 are both arranged obliquely downward, so that when the first fixing column 4 and the second fixing column 5 are inserted into the corresponding connecting holes, even if the vehicle is in complex bumpy road conditions, the first fixing column 4 and the second fixing column 5 will not fall out from the connecting holes on the connecting belt 6, which is both reliable and convenient for disassembly and assembly.

[0031] It is understandable that the inclination angles of the first fixing column 4 and the second fixing column 5 can be selected according to actual design requirements, for example, 15±5 degrees, and no excessive restrictions are imposed here.

[0032] A rib 11 is also fixedly provided around the end of the second outlet connecting sleeve 3 away from the cover body 1. The outer diameter of the rib 11 is larger than the diameter of the second outlet connecting sleeve 3. The setting of the rib 11 facilitates the use of binding structures such as PVC tape or cable ties to wrap and fix on the second outlet connecting sleeve 3, thereby achieving a fixed connection between the second outlet connecting sleeve 3 and the engine wiring harness trunk, to assist in the bundling and fixing of the connecting belt 6, further improve the firmness of the installation, and complete the assembly in the main assembly workshop of the main engine factory.

[0033] like Figure 4 As shown, the second outlet connecting sleeve 3 is arranged obliquely downward, and the axis of the second outlet connecting sleeve 3 and the horizontal axis of the cover body 1 have a downward angle, which can not only adapt to the direction of the engine wiring harness trunk, but also guide the water body to make it flow downward without gathering at the second outlet connecting sleeve 3, avoiding the water body from entering the connection position of the wire and the EMS connector along the side wall of the second outlet connecting sleeve 3 and the first opening groove 12, thereby achieving a better waterproof effect.

[0034] The cover body 1, the first outlet connecting sleeve 2, the second outlet connecting sleeve 3, the first fixing column 4, the second fixing column 5 and the connecting belt 6 are all made of rubber material. This embodiment adopts EPDM, which has excellent ozone resistance, UV resistance, weather resistance, aging resistance, electrical insulation, chemical resistance, impact elasticity and acid and alkali resistance. The applicable temperature range is -50~150℃, which can meet the use environment of the engine compartment.

[0035] In this embodiment, the Shore hardness of the protective device is controlled at 60±5°. This hardness facilitates the clamping of the protective device connecting belt 6, ensures that it fits reliably, and is not easy to fall off from the first fixing column 4 and the second fixing column 5.

[0036] It should be noted that second opening grooves 13 are provided on the side walls at both ends of the cover body 1 connected to the first outlet connection sleeve 2 and the second outlet connection sleeve 3. The second opening grooves 13 on the side walls at the end of the cover body 1 are vertically arranged and are located directly below the first outlet connection sleeve 2 and the second outlet connection sleeve 3 on the corresponding end, and are connected to the corresponding first outlet connection sleeve 2 and the second outlet connection sleeve 3, so that the wiring harness passes through the end side walls of the cover body 1 and extends into the cover body 1, and the first outlet connection sleeve 2 and the second outlet connection sleeve 3 are used to cover the second opening grooves 13 at the end of the cover body 1.

[0037] Example 2 In a typical embodiment of the present invention, a method for installing an automotive EMS rubber protective device is proposed, which is as follows: When the EMS connector is assembled at the supplier's place, one end of the EMS connector is connected to the cabin wiring harness wire, and then the cover body 1 is buckled onto the EMS connector, and the EMS connector is completely covered by the cover body 1, so that the first outlet connection sleeve 2 is close to the cabin wiring harness wire; After the cover body 1 is installed in place, the cabin wiring harness wire is passed through the first open groove 12 at the bottom of the first outlet connection sleeve 2, so that the cabin wiring harness wire enters the first outlet connection sleeve 2, so as to utilize the cooperation between the first outlet connection sleeve 2 and the cover body 1 to achieve the covering protection of the connection position between the EMS connector end and the cabin wiring harness wire, and the binding structure such as PVC tape or cable tie is wrapped and fixed on the first outlet connection sleeve 2, so that the first outlet connection sleeve 2 is fixedly connected to the cabin wiring harness trunk, and the subpackaging at the supplier is completed; During assembly in the main engine plant's final assembly workshop, the other end of the EMS connector is connected to the engine harness, and then the second outlet connecting sleeve 3 of the installed protective device is sleeved on the engine harness trunk, so that the engine harness trunk passes through the first open groove 12 at the bottom of the second outlet connecting sleeve 3 and enters the second outlet connecting sleeve 3, and then the free end of the connecting belt 6 is wrapped from the bottom to the top of the second outlet connecting sleeve 3, and then connected to the first fixing column 4 and the second fixing column 5 respectively, so as to realize the bundling of the second outlet connecting sleeve 3, so as to fix the second outlet connecting sleeve 3 with the engine harness trunk, and complete the assembly in the main engine plant's final assembly workshop.

[0038] Since there is less operating space for connecting the EMS connector to the engine harness during assembly in the main engine plant's final assembly workshop, the built-in connecting belt 6 is used for binding and fixing, which is more convenient for operation and facilitates subsequent disassembly, assembly and maintenance.

[0039] In addition, during actual installation, if it is necessary to further strengthen the connection between the second outlet connection sleeve 3 and the engine wiring harness trunk, a binding structure such as PVC tape or cable tie can be used to wrap and fix it on the second outlet connection sleeve 3.

[0040] Through the above operation, not only can the EMS connector and the end wiring harness connection position thereof be protected to achieve waterproof and dustproof functions, but also the multiple assembly processes of the EMS can be adapted, and there is no need to remove and reinstall the protective device (specifically the cover body 1 and the first outlet connection sleeve 2) in different assembly processes. The installation is convenient and the operation is simple, which effectively improves the assembly efficiency and is also convenient for subsequent disassembly, assembly and maintenance. The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
