Description

Technical Field

[0001] This application relates to the field of terminal block technology, and in particular to a wire harness terminal block protection box. Background Technology

[0002] Wire harness processing is a crucial step in industries such as automotive and electronic equipment, and the processing quality of the terminals directly affects the electrical performance and reliability of the wire harness.

[0003] In related technologies, with the development of industrial automation, wire harness processing has gradually realized assembly line operation. However, due to their small and fragile characteristics, the terminal wings of the wire harness terminals are easily bent and damaged by collision or squeezing during transportation. The industry generally uses artificial plastic wrap to bundle and cover the terminals to provide transportation protection. This method is low in cost and simple to operate.

[0004] The existing methods of protecting terminals during transportation have the following problems: the plastic wrap is soft and cannot provide sufficient support, and the terminal wings are still easily damaged by external forces. Summary of the Invention

[0005] To protect the terminal wings of the wire harness terminals, this application provides a wire harness terminal protection box.

[0006] The wire harness terminal protection box provided in this application adopts the following technical solution: A wire harness terminal protection box includes an upper housing, a lower housing, and a connecting part. The upper housing and the lower housing are connected by the connecting part. The upper housing and the lower housing are closed to form a protective box body. The side walls of the protective box body are provided with wire placement grooves at intervals along the width direction. The wire placement grooves pass through both ends of the protective box body. The inner wall of one of the groove openings is provided with a Blu-Tack layer for fixing the terminal wings of the wire harness placed in the wire placement groove.

[0007] By adopting the above solution, the protective box provides mechanical protection for the wire harness, and the Blu-Tack layer, through its adhesive adsorption, tightly fixes the wire harness terminal wings in the wire placement groove, thus achieving both fixation and protection of the terminal wings.

[0008] Preferably, the depth of the wire placement groove is greater than the length of the terminal wing of the wire harness and is arranged in a tapered shape, and the diameter of one of the grooves where the Blu-Tack layer is provided is smaller than the diameter of the other groove.

[0009] By adopting the above solution, the terminal wing can be fully embedded in the wire groove with a margin. This margin provides compression space for the Blu-Tack layer, enhancing the bonding strength. The tapered structure forms a trumpet-shaped channel. When the wire harness terminal wing is inserted from the large-diameter end, it is automatically centered by the inclined surface. After entering the narrow end, it is wrapped and squeezed by the Blu-Tack layer, which facilitates the rapid entry and positioning of the wire harness terminal wing.

[0010] Preferably, one of the larger slots in the cable tray can accommodate at least two cable bundles.

[0011] By adopting the above solution, multiple wire harnesses can be inserted and fixed in a single operation, reducing repetitive operations and improving assembly efficiency.

[0012] Preferably, the wall of the cable tray is provided with a moisture-absorbing layer.

[0013] By adopting the above solution, the occurrence of metal oxidation and corrosion in wire harnesses can be reduced.

[0014] Preferably, the wall of the wire placement groove is provided with a buffer layer.

[0015] By adopting the above solution, the vibration energy generated during the transportation of the wire harness is absorbed, reducing the occurrence of force displacement and loosening of the terminal wings.

[0016] Preferably, it also includes a snap-fit ​​structure, wherein the snap-fit ​​structure comprises a male snap and a female snap that are mutually compatible. The male snap is disposed on the side wall of the lower housing, and the female snap is disposed on the side wall of the upper housing. The male snap and the female snap are engaged with each other to maintain the closed state of the upper housing and the lower housing.

[0017] By adopting the above solution, when the upper and lower shells are closed, the male buckle automatically inserts into the female buckle and completes the fastening through elastic deformation, further improving assembly efficiency.

[0018] Preferably, the upper shell, the lower shell, the connecting part, and the buckle structure are all integrally formed.

[0019] By adopting the above solution, there are no gaps between the upper shell, the connecting part and the lower shell, which improves the overall mechanical strength and saves the assembly time and cost of the snap-fit ​​structure.

[0020] Preferably, at least two opposing outer wall surfaces of the protective box away from the wiring groove are provided with anti-slip textures.

[0021] By adopting the above solution, the surface friction coefficient is increased, making it easier for workers to grip the protective box and fix the wire harness when their hands are slippery.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The protective box provides mechanical protection for the wire harness. The Blu-Tack layer uses adhesive to firmly fix the wire harness terminal wings in the wire placement groove, thus achieving both fixation and protection of the terminal wings. 2. Reduces the occurrence of wire harness displacement due to vibration, loosening, or oxidation and corrosion of metal parts; 3. Improved the efficiency of manual assembly. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a wire harness terminal protection box. (Refer to...) Figure 1-2 A wire harness terminal protection box includes an upper housing 11, a lower housing 12, and a connecting part 13. The upper housing 11 and the lower housing 12 are connected by the connecting part 13. After the upper housing 11 and the lower housing 12 are rotated and closed around the connecting part 13, a protective box body 1 with a cuboid structure is formed.

[0028] Specifically, the side wall of the protective box 1 is provided with wire placement grooves 14 at intervals along the width direction. In this embodiment, a total of four wire placement grooves 14 are provided. The wire placement grooves 14 pass through both ends of the protective box 1, and the inner wall edge of one of the groove openings of the wire placement groove 14 is provided with a Blu-Tack layer 3 to fix the terminal wings of the wire harness placed in the wire placement groove 14.

[0029] Therefore, the protective box 1 provides mechanical protection for the wire harness through its closed rectangular rigid shell and sealing characteristics. At the same time, the Blu-Tack layer 3 uses adhesive adsorption to firmly fix the wire harness terminal wings in the wire placement groove 14, reducing their displacement or detachment due to force.

[0030] Furthermore, the elastic deformation capability of Blu-Tack can adapt to the thickness difference of the terminal wings, increasing the tightness of the adsorption and bonding. Blu-Tack can also be reused, effectively reducing manufacturing costs. At the same time, it has the effect of dust adhesion and sealing and waterproofing, working together with the protective box 1 to provide multi-dimensional fixation and protection for the internal wire harness and terminal wings.

[0031] On the other hand, the depth of the wire placement groove 14 is greater than the length of the terminal wing of the wire harness, and the diameter of one of the grooves where the Blu-Tack layer 3 is fixed is smaller than the diameter of the other groove, that is, the wire placement groove 14 is set in a tapered structure.

[0032] Correspondingly, the terminal wing can be fully embedded in the groove, reducing the occurrence of terminal wing displacement, loosening or deformation under force. At the same time, the wire groove 14 also provides a margin for the compression space of the Blu-Tack layer 3 to enhance the fixing stability and vibration resistance of the Blu-Tack layer 3 and accommodate manufacturing and assembly errors.

[0033] Furthermore, the tapered structure of the wire groove 14 forms a trumpet-shaped channel. When the wire harness terminal wing is inserted from the large-diameter end, it is automatically centered by the inclined surface. After entering the narrow end, it is wrapped and squeezed by the Blu-Tack layer 3, achieving a progressive fixation that gets tighter as it is inserted. At the same time, the wedge effect generated by the diameter difference increases the pressure on the contact surface between the terminal wing and the Blu-Tack when the wire harness is subjected to axial tension, thereby improving the adhesion, effectively resisting the displacement caused by vibration, and reducing the shaking of the terminal wing in the groove gap.

[0034] Furthermore, one of the larger slots in the wire trough 14 can accommodate at least two wire harnesses. By adopting a multi-wire parallel arrangement, it supports the synchronous insertion and adsorption fixation of multiple wire harnesses, reduces repetitive operations, and improves assembly efficiency.

[0035] On the other hand, in this embodiment, the wall of the cable tray 14 located in the upper housing 11 is covered with a moisture-absorbing layer 6, which is made of silica gel desiccant. The wall of the cable tray 14 located in the lower housing 12 is covered with a buffer layer 2, which is made of rubber foam material.

[0036] Therefore, the moisture-absorbing layer 6 actively adsorbs moisture in the wire tray 14 using capillary action, reducing the humidity in the tray and thus reducing the oxidation and corrosion of the wire harness metal. At the same time, the buffer layer 2 absorbs vibration energy during wire harness transportation, attenuates external acceleration, and effectively reduces friction damage between the wire harness and the tray wall, as well as force displacement and loosening.

[0037] In addition, a snap-fit ​​structure 4 is also included. In this embodiment, the snap-fit ​​structure includes a male snap-fit ​​41 that is protruding and a female snap-fit ​​42 that is annularly recessed. The male snap-fit ​​41 and the female snap-fit ​​42 are adapted to each other. The male snap-fit ​​41 is fixed to the side wall of the lower housing 12, and the female snap-fit ​​42 is correspondingly fixed to the side wall of the upper housing 11. The male snap-fit ​​41 and the female snap-fit ​​42 are engaged with each other to maintain the closed state of the upper housing 11 and the lower housing 12.

[0038] Correspondingly, when the upper shell 11 and the lower shell 12 are closed, the male buckle 41 automatically inserts into the female buckle 42 and completes the fastening through elastic deformation, further improving assembly efficiency. After the male buckle 41 and the female buckle 42 are fastened, a certain vertical separation force needs to be applied to separate them, which reduces the accidental pop-out caused by vibration of the protective box 1 during transportation.

[0039] On the other hand, the upper shell 11, lower shell 12, connecting part 13 and buckle structure 4 are all integrally molded. By adopting an integrated injection molding process, the upper shell 11, lower shell 12, connecting part 13 and buckle structure 4 are integrated into a seamless whole, reducing the assembly seams of the traditional split structure, improving the overall bending strength, and at the same time reducing the separate installation process of buckle structure 4, reducing the unit production cost.

[0040] In addition, in this embodiment, the upper and lower opposing outer wall surfaces of the protective box 1 away from the wire placement groove 14 are provided with wavy anti-slip textures 5. By increasing the surface friction coefficient, it is easier for workers to grip the protective box 1 to fix and assemble the wire harness when their hands are wet and slippery.

[0041] Furthermore, the anti-slip texture 5 can also improve tactile feedback through texture depth, thereby increasing the accuracy of grasping during blind operation.

[0042] The implementation principle of a wire harness terminal protection box in this application embodiment is as follows: the worker opens the protection box 1 and places the wire harness terminal in the wire placement groove 14. After the protection box 1 is closed, it provides mechanical protection for the terminal. The Blu-Tack layer 3 pre-coated in the groove makes the terminal wings fit into the groove wall without gaps through intermolecular forces, thus achieving the fixation and protection of the wire harness terminal wings.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
