Description

Technical Field

[0001] This invention relates to the field of automotive electrical boxes for road vehicles, and in particular to a matching device for automotive electrical boxes. Background Technology

[0002] With the development of the automotive industry and the application of autonomous driving technology, vehicle safety requirements are becoming increasingly stringent, and the safety requirements for electrical boxes, as the central control unit of automotive electrical systems, are also rising. As one of the most important components protecting the wiring in an electrical box, ensuring a safe and stable connection between the socket-type fuse and the male connector is a crucial aspect of electrical box design. To prevent abnormal disconnection between the socket-type fuse and the male connector during use, in addition to relying on mutual insertion, clips are typically used to lock the male connector. Clips can be inserted from the back, front, or side of the electrical box, but current clip structures have inherent drawbacks. While back-inserted clips can lock the male connector, they are not conducive to the assembly of automotive electrical box wiring harnesses; side-inserted clips occupy more space during installation and are not conducive to individual component disassembly. Therefore, to improve efficiency and reduce the space occupied by insertion, a front-inserted clip solution is needed. Currently, the front-inserted clip solution cannot achieve complete locking of the male connector; it only serves to enhance the connection capability, and the male connector is prone to detaching from the electrical box under significant pulling force. Furthermore, with the continuous development of miniaturization and lightweighting, electrical boxes and their accessories are also being gradually optimized. Socket-type fuses are becoming smaller and lighter, and the clips are also being optimized to adapt to the future development trend of socket-type fuses.

[0003] Therefore, how to effectively solve the problem of front-mounted clips in a limited space, significantly enhance assembly operability, circuit stability, and maintainability, and meet the miniaturization trend of socket-type fuses is an urgent problem to be solved for socket-type fuse clips. Summary of the Invention

[0004] To address the shortcomings of the aforementioned background technology, this invention proposes a mating device for automotive electrical boxes, which solves the problems of poor locking performance, inconvenient disassembly and assembly, large space occupation, and inability to adapt to the miniaturization of socket-type fuses in the prior art.

[0005] The technical solution of this invention is implemented as follows: A mating device for an automotive electrical box includes a socket-type fuse, an electrical box fuse plastic module, and a male plug. The male plug has at least one positioning hole, and the electrical box fuse plastic module has an elastic latch that engages with the positioning hole. It also includes a socket-type fuse clip body that engages with the socket-type fuse. The socket-type fuse clip body is an A1 type fuse clip body, an A1S type fuse clip body, or an A4 type fuse clip body. The fuse holder body; the A1 type fuse holder body, A1S type fuse holder body and A4 type fuse holder body all include a basic holder body. The bottom of the basic holder body is provided with a flexible latch locking structure and a male plug through hole adapted to the male plug. When the basic holder body and the fuse plastic module of the electrical box are engaged in the insertion and removal direction, the flexible latch locking structure is inserted into the back of the flexible latch, and blocks the flexible latch in the elastic unlocking direction, so as to realize the locking engagement between the flexible latch and the positioning hole.

[0006] Furthermore, when the socket-type fuse clip body is an A1 type fuse clip body or an A1S type fuse clip body, the basic clip body is a box-shaped structure, and at least one hanging platform is provided on the side wall of the basic clip body. A hanging groove is provided on the electrical box fuse plastic module, and the hanging platform and the hanging groove are engaged and matched along the insertion and removal direction.

[0007] Furthermore, the base clip body is provided with two symmetrically arranged elastic arms, and the mounting platform is set on the elastic arms and is an integral structure with the elastic arms; when the base clip body is installed, the elastic arms are compressed inward along the elastic direction, so that the mounting platform and the mounting slot are connected; when the socket-type fuse is inserted into the preset position in the base clip body, the socket-type fuse blocks the elastic arms in the elastic unlocking direction, realizing the mutual locking of the male plug, the base clip body and the socket-type fuse.

[0008] Furthermore, when the socket-type fuse clip body is an A1 type fuse clip body, the upper part of the basic clip body is provided with a reinforcing side skirt, and the reinforcing side skirt is provided with a pressing surface for assisting the basic clip body to cooperate with the electrical box fuse plastic module in the insertion and removal direction.

[0009] Furthermore, a reinforcing rib is provided on the inner wall of the side skirt facing the inner side of the base clip body, and the reinforcing rib is connected to the base clip body in a transitional manner; the reinforcing rib is provided with a guide chamfer that cooperates with the socket-type fuse to guide and limit the socket-type fuse.

[0010] Furthermore, the outer wall of the reinforced side skirt is symmetrically provided with unlocking protrusions for disassembling the basic clip body.

[0011] Furthermore, when the socket-type fuse clip body is an A1S type fuse clip body, the upper part of the basic clip body is provided with two symmetrical U-shaped side skirts, and a reinforcing rib plate two is provided between the U-shaped side skirts and the basic clip body to enhance the connection strength; the reinforcing rib plate one is provided with a guide chamfer that cooperates with the socket-type fuse to guide and limit the socket-type fuse.

[0012] Furthermore, the outer wall of the basic clip body is provided with a strip plate that is adapted to the plastic part module of the electrical box fuse, and the strip plate is located below the side plate of the U-shaped side skirt.

[0013] Furthermore, when the socket-type fuse clip body is an A4 type fuse clip body, the basic clip body has a U-shaped structure.

[0014] Furthermore, the upper part of the U-shaped structure is provided with two symmetrical hanging ears, and the two hanging ears are provided with baffles that connect to the base clip body. The baffles are adapted to the grooves on the plastic parts module of the electrical box fuse.

[0015] The beneficial effects of this invention are as follows: The A1 type fuse clip achieves quadruple interlocking of the male plug, the electrical box body, the A1 type fuse clip body, and the A1 type fuse through the elastic latch locking structure, the cooperation between the mounting platform and the mounting groove, and the blocking effect of the A1 type fuse on the elastic support arm. This significantly enhances the safety and stability of the connection and effectively prevents the male plug from coming out and the A1 type fuse from coming loose. At the same time, the clip adopts a front insertion method, which occupies little space and is compatible with the multi-circuit modular design of the electrical box. The design of the reinforcing rib, pressing surface, and unlocking protrusion greatly improves the convenience of installation and disassembly, reducing the time and labor costs of production and maintenance. In addition, the clip body can be modified to form various variants to adapt to different models of socket-type fuses such as A1S and A4, meeting the development trend of miniaturization and lightweighting of socket-type fuses, and has strong versatility.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Existing socket-type fuses include TYPE A1, abbreviated as A1 type fuse, standard: GB / T 31465.4 (adopting ISO8820-4), such as the JCASE series produced by Lite-On, which are compatible with A1 type fuse clips; TYPE A1S, abbreviated as A1S type fuse, standard: GB / T 31465.4, such as the LPJCASE series produced by Lite-On, which are compatible with A1S type fuse clips; and TYPE A4, abbreviated as A4 type fuse, standard: GB / T 31465.4, such as the MCASE series produced by Lite-On, which are compatible with A4 type fuse clips. Among them, A1S and A4 type fuses are miniaturized socket-type fuses derived from A1 type fuses.

[0033] like Figures 1-7 As shown in Embodiment 1, a mating device for an automotive electrical box includes a socket-type fuse, an electrical box fuse plastic module 1, and a male plug 2. The male plug 2 has at least one positioning hole 4. The electrical box fuse plastic module 1 has an elastic latch 5 that engages with the positioning hole 4. It also includes a socket-type fuse clip body, which is an A1 type fuse clip body 6, and the socket-type fuse is an A1 type fuse 3.

[0034] The A1 type fuse clip body 6 includes a basic clip body. The bottom of the basic clip body is provided with a flexible latch locking structure 7 and a male plug through hole 8 adapted to the male plug 2. When the basic clip body and the electrical box fuse plastic module 1 are engaged in the insertion and removal direction, the flexible latch locking structure 7 is inserted into the back of the flexible latch 5, and blocks the flexible latch 5 in the elastic unlocking direction, so as to realize the locking engagement between the flexible latch 5 and the positioning hole 4. The A1 type fuse 3 is inserted into the A1 type fuse clip body 6 in the insertion and removal direction and is engaged with the pin 9 of the male plug 2 that passes through the male plug through hole 8.

[0035] The elastic latch 5 undergoes elastic deformation in the elastic locking direction perpendicular to the insertion and removal direction, thereby achieving a snap-fit ​​with the positioning hole 4; the male plug through hole 8 is a through slot structure, allowing the male plug 2 to pass through and avoid obstruction; the base clip body and the electrical box fuse plastic module 1 are in clearance fit, and the top inner side of the electrical box fuse plastic module 1 and the back of the elastic latch 5 are provided with guide angles to assist the base clip body in smoothly inserting into the electrical box fuse plastic module 1.

[0036] like Figures 8-10 As shown in Embodiment 2, a mating device for an automotive electrical box, based on the technology of Embodiment 1, uses an A1S type fuse clip body 22 and an A1S type fuse 23 as the socket-type fuse. The A1S type fuse clip body 22 includes a basic clip body, the bottom of which is provided with an elastic latch locking structure 7 and a male plug through hole 8 adapted to the male plug 2. When the basic clip body and the electrical box fuse plastic module 1 are mated in the insertion and removal direction, the elastic latch locking structure 7 is inserted into the back of the elastic latch 5, forming a stop on the elastic latch 5 in the elastic unlocking direction, realizing the locking engagement between the elastic latch 5 and the positioning hole 4. The A1S type fuse 23 is inserted into the A1S type fuse clip body 22 in the insertion and removal direction and is mated with the pin 9 of the male plug 2 that passes through the male plug through hole 8.

[0037] The A1S type fuse is a miniaturized socket-type fuse derived from the A1 type fuse. It retains the core structure of flexible latch locking, hook positioning, and mutual locking, making it suitable for miniaturized assembly spaces.

[0038] like Figures 11-13 As shown in Embodiment 3, a mating device for an automotive electrical box, based on the technology of Embodiment 1, uses an A4 type fuse clip body 24 and an A4 type fuse 25 as the socket-type fuse. The A4 type fuse clip body 24 includes a basic clip body, the bottom of which is provided with an elastic latch locking structure 7 and a male plug through hole 8 adapted to the male plug 2. When the basic clip body and the electrical box fuse plastic module 1 are mated in the insertion and removal direction, the elastic latch locking structure 7 is inserted into the back of the elastic latch 5, forming a stop on the elastic latch 5 in the elastic unlocking direction, realizing the locking engagement between the elastic latch 5 and the positioning hole 4. The A4 type fuse 25 is inserted into the A4 type fuse clip body 24 in the insertion and removal direction and is mated with the pin 9 of the male plug 2 that passes through the male plug through hole 8.

[0039] The A4 type fuse is a miniaturized and lightweight socket-type fuse derived from the A1 type fuse, with a simplified structure while retaining the core locking function.

[0040] like Figures 1-10 As shown in Embodiment 4, a mating device for an automotive electrical box is provided. When the socket-type fuse clip body is an A1 type fuse clip body 6 or an A1S type fuse clip body 22, the basic clip body is a box-shaped structure, which includes a rectangular side and a bottom plate. At least one mounting platform 10 is provided on the side wall of the basic clip body, and a hanging groove 11 is provided on the electrical box fuse plastic module 1. The mounting platform 10 and the hanging groove 11 are engaged and mated along the insertion and removal direction to achieve the initial positioning and engagement of the socket-type fuse clip body and the electrical box fuse plastic module 1.

[0041] In this embodiment, the base clip body has two symmetrically arranged elastic arms 12, and the mounting platform 10 is mounted on the elastic arms 12 and is an integral structure with the elastic arms 12. When the base clip body is installed, the elastic arms 12 are compressed inward along the elastic direction, so that the mounting platform 10 and the mounting slot 11 are engaged. When the socket-type fuse is inserted into the preset position in the base clip body, the socket-type fuse blocks the elastic arms 12 in the elastic unlocking direction, realizing the mutual locking of the male plug 2, the base clip body, and the socket-type fuse. The elastic arms 12 and the base clip body are integrally formed, and the elastic deformation direction of the elastic arms 12 is perpendicular to the insertion and removal direction of the base clip body.

[0042] like Figures 1-7 As shown in Embodiment 5, a mating device for an automotive electrical box, based on Embodiment 1, when the socket-type fuse clip body is an A1-type fuse clip body 6, a reinforcing side skirt 13 is provided on the upper part of the basic clip body. The reinforcing side skirt 13 is provided with a pressing surface for assisting the basic clip body in mating with the electrical box fuse plastic module 1 along the insertion and removal direction. The pressing surface is a planar structure, and applying force to press the pressing surface can realize the rapid pressing of the basic clip body. The reinforcing side skirt 13 and the basic clip body are integrally formed structures.

[0043] In this embodiment, the reinforcing side skirt 13 is a rectangular base structure of the A1 type fuse clip body 6. A reinforcing rib 15 is provided on the inner wall of the reinforcing side skirt 13 facing the inner side of the base clip body. The reinforcing rib 15 is transitionally connected to the base clip body. The reinforcing rib 15 has a guide chamfer that cooperates with the socket-type fuse to guide and limit its movement. The reinforcing rib 15 and the base clip body are connected by an arc transition, improving the overall structural strength. The guide chamfer ensures accurate insertion of the socket-type fuse into the pins 9 of the male plug 2.

[0044] In this embodiment, the outer wall of the reinforced side skirt 13 is symmetrically provided with unlocking protrusions 17 for disassembling the basic clip body. The outer wall of the unlocking protrusions 17 has a non-slip structure, which facilitates hand gripping during disassembly and provides a force application point for disassembling the basic clip body.

[0045] like Figures 8-10 As shown in Embodiment 6, a socket-type fuse clip for an automotive electrical box, based on Embodiment 2, when the socket-type fuse clip body is an A1S type fuse clip body 22, the upper part of the basic clip body is provided with two symmetrical U-shaped side skirts 14, and a reinforcing rib plate 18 for strengthening the connection strength is provided between the U-shaped side skirts 14 and the basic clip body; a strip plate 19 adapted to the fuse plastic module 1 of the electrical box is provided on the outer wall of the basic clip body, and the strip plate 19 is located below the side plate of the U-shaped side skirts 14.

[0046] In this embodiment, the reinforcing rib 18 is arranged along the insertion and removal direction to prevent structural breakage during installation and disassembly; the strip plate 19 extends along the insertion and removal direction and cooperates with the reinforcing rib of the electrical box fuse plastic module 1 to prevent the A1S type fuse clip body 22 from tilting or shifting during installation / use.

[0047] like Figures 11-13 As shown in Embodiment 7, a socket-type fuse clip for an automotive electrical box, based on Embodiment 3, when the body of the socket-type fuse clip is an A4 type fuse clip body 24, the basic clip body has a U-shaped structure. The upper part of the A4 type fuse clip body 24 is provided with two symmetrical hanging ears 16. The two hanging ears 16 are provided with baffles 20 that are connected to the A4 type fuse clip body 24. The baffles 20 are adapted to the grooves 21 on the plastic part module 1 of the electrical box fuse.

[0048] In this embodiment, the basic clip body is U-shaped with the opening facing the male plug 2 side; after the baffle 20 is inserted into the groove 21, it forms a circumferential positioning fit, which restricts the circumferential rotation of the A4 type fuse clip body 24.

[0049] The specific assembly and disassembly procedures are as follows:

[0050] First, insert the male plug 2 upwards into the electrical box fuse plastic module 1 in the insertion / removal direction, so that the elastic hook 5 is hooked and fixed with the positioning hole 4; then press the pressing surface and insert the base clip body downwards into the electrical box fuse plastic module 1 in the insertion / removal direction, so as to complete the hooking of the mounting platform 10 and the mounting groove 11 and the locking of the elastic hook 5 by the elastic hook locking structure 7; finally, insert the socket-type fuse downwards into the base clip body in the insertion / removal direction, and make conductive connection with the pin 9 of the male plug 2 to complete mutual locking and complete the installation.

[0051] First, pull the socket-type fuse upwards in the insertion / removal direction; then press the mounting plate 10 on the elastic support arm 12 inwards, while simultaneously holding the unlocking protrusion 17 and applying upward force in the insertion / removal direction to pull out the base clip body; finally, squeeze the elastic hook 5 in the elastic unlocking direction to release its connection with the positioning hole 4, and remove the male plug 2 downwards in the insertion / removal direction to complete the disassembly.

[0052] like Figures 1-3As shown in Embodiment 8, a socket-type fuse clip for an automotive electrical box comprises an electrical box fuse plastic module 1, a male plug 2, and a socket-type fuse, which are sequentially inserted and connected. The socket-type fuse clip 6 has an elastic latch locking structure 7 and a through-hole 8 for the male plug 2 at its bottom. It also has elastic support arms 12 with mounting platforms 10 on both sides and internal limiting ribs. The elastic latch locking structure 7 is used to insert into the back of the elastic latch 5 of the electrical box fuse plastic module 1 and block it in the elastic unlocking direction. The mounting platform 10 is used to engage with the mounting groove 11 of the electrical box fuse plastic module 1 in the insertion / removal direction. The reinforcing rib 15 guides and limits the socket-type fuse, and after insertion, it blocks the elastic support arm 12 in the elastic unlocking direction, thus achieving mutual locking between the male plug 2, the electrical box fuse plastic module 1, the socket-type fuse clip 6, and the A1 type socket-type fuse.

[0053] The number of the elastic latch locking structure 7 is two, and the two elastic latch locking structures 7 are symmetrically arranged at the bottom of the socket-type fuse clip 6, and the bottom of the elastic latch locking structure 7 is provided with a chamfered guide structure.

[0054] The socket-type fuse clip 6 and the electrical box fuse plastic module 1 are in clearance fit. The top inner side of the electrical box fuse plastic module 1 and the back of the elastic hook 5 are provided with chamfered guide structures, which are adapted to the chamfered guide structure of the elastic hook locking structure 7.

[0055] The top of the socket-type fuse clip 6 is provided with a pressing surface, and the pressing surface is provided with unlocking protrusions 17 symmetrically on both sides. The top of the mounting platform 10 is provided with a chamfered unlocking structure. The unlocking protrusions 17 and the chamfered unlocking structure cooperate to unlock and remove the socket-type fuse clip 6.

[0056] The elastic support arm 12 can be compressed inward along the elastic direction. Pressing the pressing surface allows the hanging platform 10 to be smoothly inserted into the hanging slot 11 of the electrical box fuse plastic module 1 through the compression of the elastic support arm 12.

[0057] The top of the reinforcing rib 15 is provided with a chamfered guide structure. The reinforcing rib 15 guides the insertion of the A1 type fuse through the chamfered guide structure and radially limits the inserted socket-type fuse.

[0058] The elastic support arm 12 and the socket-type fuse clip 6 are integrally formed structures, and the elastic deformation direction of the elastic support arm 12 is perpendicular to the insertion and removal direction of the socket-type fuse clip 6.

[0059] The number of male plug through holes 8 is two, and the two male plug through holes 8 and the two elastic latch locking structures 7 are arranged alternately at the bottom of the socket-type fuse clip 6.

[0060] The A1S type fuse clip is a variant of the A1 type fuse clip, and the A1S type fuse clip is additionally provided with a strip plate 19, which is used to prevent the A1S type fuse clip 6 from tilting during installation.

[0061] The A4 type fuse clip is a variant of the A1 type fuse clip. For the sake of structural simplification, it retains the core locking and disassembly structures of the elastic latch locking structure 7, the mounting platform 10, and the unlocking protrusion 17.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
