Description

Technical Field

[0001] This utility model relates to the technical field of wire harness protection devices, and in particular to a wire harness docking position protection device. Background Technology

[0002] Protecting wire harness connection points has wide applications in various fields and scenarios, such as the automotive industry, aerospace, and home appliances. Its main purpose is to prevent adverse effects from external environmental factors such as moisture, dust, and mechanical stress on electrical connections, thereby avoiding electrical faults. Ensuring the reliability and safety of circuit systems is a core consideration in every design and application involving electrical connections. Especially in harsh working environments, effective protective measures are crucial for maintaining normal equipment operation and extending its service life.

[0003] However, current methods for protecting wire harness connections have certain technical shortcomings. The common practice is to secure the two wires together by wrapping insulating tape around their surfaces to achieve fixation and isolation from the surrounding environment. In harsh environments, an additional plastic shell is often added for enhanced protection. However, this method exhibits significant deficiencies in practical applications: First, the connection strength secured with insulating tape is not ideal, and the connection can easily detach due to external pulling during subsequent laying or pulling of the wires. This not only reduces the efficiency of power or signal transmission but may also create safety hazards. Therefore, we have designed a wire harness connection point protection device to enhance the strength and protective performance of the connection points. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a wire harness docking position protection device.

[0005] A wire harness docking protection device includes a first protective shell, a hinge, and a second protective shell. The second protective shell is hinged to one side of the first protective shell. The first and second protective shells cover each other and are used to cover the docking position of the wire harnesses at both ends, thereby protecting the docking connection seat of the wire harnesses. A connection seat is fixedly provided at the end of the first and second protective shells away from the hinge. The connection seat is used to tighten the first and second protective shells after they are covered, thereby protecting the wire harnesses after docking. It also includes a tensioning bolt and a clamping block. Tensioning bolts are rotatably connected to both ends of the inner sidewalls of the first and second protective shells. Clamping blocks are symmetrically and slidably connected inside the first and second protective shells. The clamping blocks are elastic and are threadedly engaged with the tensioning bolts.

[0006] To further explain, the clamping surface of the clamping block is provided with rough anti-slip texture, which is used to improve the stability and sealing of the clamping block after clamping the wire harness.

[0007] To further explain, multiple slots are symmetrically provided at both ends of the inner walls of the first and second protective shells. A fastening plate is slidably fitted into the slots of both the first and second protective shells. The fastening plate is provided with a groove for clamping the wire harness. The fastening plate is used to support and clamp the wire harness.

[0008] To further explain, the inner walls of the first and second protective shells are fitted with sliding blocks near the slots. The end of the block is a pointed tip. An elastic element is provided between the block and the corresponding shell. The outer wall of the fastening plate is provided with a slot for the block. When the fastening plate is slidably inserted into the corresponding slot, the fastening plate overcomes the elastic force of the elastic element and presses against the block.

[0009] To further explain, a sealing gasket is provided on the side of the snap-fit ​​plate, and a sealing gasket is also provided on the closing end face of the first protective shell and the second protective shell. The sealing gasket is used to improve the sealing performance of the snap-fit ​​plate in the first protective shell or the second protective shell.

[0010] To further explain, both the first and second protective shells have cover plates fixedly installed near the opening of the tightening bolt. The cover plates seal and cover the openings on the outer walls of the first and second protective shells, and are used to protect the tightening bolt and other components inside the first and second protective shells.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a first protective shell and a second protective shell connected by a hinge to cover the wire harness position, forming a closed protective space, which effectively prevents damage to the wire harness connector from the external environment, improves connection stability and service life. At the same time, the tightening bolt and the clamping block are used together, and the position of the clamping block is adjusted by the thread transmission to achieve clamping of wire harnesses of different sizes, improving the versatility and clamping stability of the device.

[0013] 2. The snap-fit ​​plate of this utility model is slidably installed in the protective shell through a slot, which is convenient for disassembly and replacement. With the groove structure, it can effectively support and position the wire harness, improving the overall assembly efficiency.

[0014] 3. This utility model can also effectively prevent dust, moisture and other impurities from entering the protective shell through the sealing gasket on the fastening plate and the cover plate structure, protecting the wiring harness connection from environmental influences; the cover plate blocks the opening of the tightening bolt, reducing the entry of external impurities, protecting the internal adjustment structure, thereby extending the overall service life of the device.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] A wire harness docking position protection device, such as Figures 1-4 As shown, the device includes a first protective shell 1, a hinge 2, and a second protective shell 3. The second protective shell 3 is hinged to one side of the first protective shell 1 via the hinge 2. The first and second protective shells 1 and 3 cover each other, covering the mating positions of the two wire harnesses 100, thereby protecting the connecting seat 4 at the mating points of the wire harnesses 100. A connecting seat 4 is fixedly installed at the end of the first and second protective shells 1 and 3 away from the hinge 2. The connecting seat 4 is used to tighten the first and second protective shells 1 and 3 after they are closed, thereby protecting the wire harnesses 100 after mating. 0; It also includes a tensioning bolt 5 and a clamping block 6. The tensioning bolt 5 is rotatably connected to both ends of the inner sidewall of the first protective shell 1 and the second protective shell 3. The clamping block 6 is symmetrically slidably connected inside the first protective shell 1 and the second protective shell 3. The clamping block 6 is elastic. The clamping block 6 and the tensioning bolt 5 are threadedly engaged. When the first protective shell 1 and the second protective shell 3 cover the wire harness 100 that is connected at both ends, by turning the tensioning bolt 5, the tensioning bolt 5 drives the corresponding clamping blocks 6 on both sides to clamp the wire harness 100 that is connected at both ends inward through the threaded transmission, thereby enhancing the stability of the connection position of the wire harness 100.

[0022] like Figure 3 As shown, the clamping surface of the clamping block 6 is provided with rough anti-slip texture 7. The anti-slip texture 7 is used to improve the stability and sealing of the clamping block 6 after clamping the wire harness 100.

[0023] like Figure 4 As shown, multiple slots 8 are symmetrically provided at both ends of the inner walls of the first protective shell 1 and the second protective shell 3. A fastening plate 9 is slidably installed in the slots 8 of the first protective shell 1 and the second protective shell 3. A groove for clamping the wire harness 100 is provided on the fastening plate 9. The fastening plate 9 is used to support and clamp the wire harness 100.

[0024] like Figure 4 As shown, a locking block 10 is slidably connected to the inner wall of the first protective shell 1 and the second protective shell 3 near the slot 8. The end of the locking block 10 is a pointed tip. An elastic element 11 is provided between the locking block 10 and the corresponding shell. A slot 12 adapted to the locking block 10 is opened on the outer wall of the fastening plate 9. When the fastening plate 9 is slidably inserted into the corresponding slot 8, the fastening plate 9 overcomes the elastic force of the elastic element 11 and presses against the locking block 10. When the fastening plate 9 is fully inserted into the slot 8, the locking block 10 pops out under the action of the elastic element 11 and is locked in the slot 12 of the fastening plate 9, thereby improving the stability of the fastening plate 9 installed on the first protective shell 1 and the second protective shell 3.

[0025] like Figure 2 and Figure 4 As shown, a sealing gasket 13 is provided on the side of the snap-fit ​​plate 9, and a sealing gasket 13 is also provided on the closing end face of the first protective shell 1 and the second protective shell 3. The sealing gasket 13 is used to improve the sealing performance of the snap-fit ​​plate 9 in the first protective shell 1 or the second protective shell 3.

[0026] like Figure 3 As shown, a cover plate 14 is fixedly installed on both the first protective shell 1 and the second protective shell 3 near the opening of the tightening bolt 5. The cover plate 14 seals and blocks the opening on the outer wall of the first protective shell 1 and the second protective shell 3. The cover plate 14 is used to protect the components such as the tightening bolt 5 inside the first protective shell 1 and the second protective shell 3, and to prevent dust and other impurities from entering the interior of the first protective shell 1 and the second protective shell 3 through the opening, which would have an adverse effect on the connection of the wire harness 100.

[0027] First, select a suitable fastening plate 9 according to the specifications of the wire harness 100. Slide the fastening plate 9 into the slots 8 at both ends of the inner walls of the first protective shell 1 and the second protective shell 3. When inserted, the fastening plate 9 overcomes the elastic force of the elastic element 11 and compresses the locking block 10 inward. After the fastening plate 9 is fully inserted, the locking block 10 automatically pops out under the action of the elastic element 11 and locks into the slot 12 on the outer wall of the fastening plate 9 to achieve locking. At the same time, the sealing gasket 13 on the side of the fastening plate 9 ensures sealing. Then, place the connected wire harness 100 connector 4 into the groove of the fastening plate 9 of the lower protective shell, and cover the upper protective shell with the hinge 2 to cover the joint. Use the connector fixed at the end of the protective shell away from the hinge 2 to secure the connection. The connector 4 (such as a bolt) tightens and secures the two shells. Next, the tension bolts 5 at both ends of the inner wall of the protective shell are turned. The threaded drive of the tension bolts 5 drives the elastic clamping blocks 6, which are symmetrically slidably connected on both sides, to move towards each other, thereby tightly clamping the two ends of the wire harness 100 placed in the groove of the fastening plate 9. The rough anti-slip texture 7 on the surface of the clamping block 6 significantly enhances the clamping stability and the sealing effect at this point, effectively improving the mechanical stability of the wire harness 100 docking position. Finally, a cover plate 14 is installed at the opening of the tension bolt 5 on the outer wall of the protective shell to seal and block the opening to prevent dust and other impurities from entering, protect the tension bolt 5 and extend its service life, and ensure that the wire harness 100 connector 4 is in a clean, stable, and sealed protective environment.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
