Description

Technical Field

[0001] This utility model relates to the field of vehicle wiring harness connector technology, specifically a vehicle wiring harness connector assembly. Background Technology

[0002] Vehicle wiring harness connectors are key connection components in the automotive electrical system, responsible for establishing stable and reliable electrical connections between power, signal, and electronic devices.

[0003] Currently, most existing plugs use an integrated fixing structure, with the fixing component tightly connected to the plug body, making it difficult to disassemble and replace them separately. Once the fixing component is damaged, such as by a broken clip or deformation of the fixing structure, the entire plug often needs to be replaced. This not only increases maintenance costs but also wastes resources. In view of this, we propose an automotive wiring harness connector assembly. Utility Model Content

[0004] The main objective of this invention is to provide a vehicle wiring harness connector assembly that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model proposes a vehicle wiring harness connector assembly, including a first connector and a second connector. The first connector is snapped into the second connector by a fixing assembly. The fixing assembly includes a base, a rod, and a spring. A fixing block is connected to the outer wall of the base, and there are two fixing blocks in total, which are symmetrically distributed on the outer wall of the base.

[0006] Preferably, the fixing block is hinged to a rod, and a clip is connected to the outer wall of one end of the rod.

[0007] Preferably, one end of the spring is fixedly connected to the inner wall of the rod on the side away from the clamp head, and the other side of the spring is connected to the outer wall of the base.

[0008] Preferably, the outer wall of the plug is connected to slots on both sides, the slots are slidably connected to the base, and the slots and the base are respectively provided with positioning hole one and positioning hole two.

[0009] Preferably, both the rod body and the base end are provided with slots, and the two sets of slots are located on the same horizontal plane, and the slots are fitted with locking blocks.

[0010] Preferably, both ends of the plug one and plug two are provided with protective sleeves to protect the wire harness.

[0011] Preferably, the plug has two openings with grooves.

[0012] This utility model provides a vehicle wiring harness connector assembly. It has the following advantages:

[0013] (1) The vehicle wiring harness connector assembly has slots on both sides of the outer wall of the connector. The base of the fixing component is slidably connected to the slots, and both have positioning holes 1 and 2 respectively. The base is fixed by screwing a fixing screw through positioning hole 1 and into positioning hole 2. This detachable structure design means that when the fixing component is damaged, there is no need to carry out complicated repairs or replacements of the entire vehicle wiring harness connector assembly. Simply unscrew the fixing screw from the positioning hole and pull the base out of the slot to easily replace the fixing component. This greatly simplifies the maintenance process, reduces the difficulty and time cost of repair, and reduces the material waste caused by replacing the entire component, effectively reducing maintenance costs.

[0014] (2) During the connection process, the two ends of the vehicle wiring harness connector assembly press against the clips on the rod, causing the rod to rotate around the hinge point and the spring to be stretched. After the connector is in place, the spring force causes the rod to return to its original position, and the clips engage with the front edge of the second connector to complete the connection. In addition, corresponding slots are provided on the base and the rod, and inserting a clip can further fix the position of the rod and prevent it from shaking. This double-protection connection structure can effectively ensure the stability of the connection between the first and second connectors and prevent the connection from loosening or separating under external force.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model proposes a vehicle wiring harness connector assembly, including a first connector 1 and a second connector 2. Both the first connector 1 and the second connector 2 are provided with protective sleeves 3 at their ends. The second connector 2 has a groove 21 for protecting the wiring harness. The first connector 1 is snapped into the second connector 2 by a fixing component 4. The fixing component 4 includes a base 41, a rod 42, and a spring 43. The outer wall of the base 41 is connected to a fixing block 411, and there are two fixing blocks 411, which are symmetrically distributed on the outer wall of the base 41. The rod 42 is hinged to the fixing block 411. A clip 421 is connected to the outer wall of one end of the rod 42. One end of the spring 43 is fixedly connected to the inner wall of the rod 42 away from the clip 421. The other side of the spring 43 is connected to the outer wall of the base 41.

[0027] In an embodiment of this utility model, in order to replace the fixing component 4, specifically, slots 11 are connected to both sides of the outer wall of the plug 1, the slots 11 are slidably connected to the base 41, and the slots 11 and the base 41 are respectively provided with positioning hole 12 and positioning hole 2 412.

[0028] Furthermore, both the rod body 42 and the base 41 have slots 44 at their ends, and the two sets of slots 44 are located on the same horizontal plane, with a locking block 45 fitting into each slot 44.

[0029] In this utility model, when installing the fixing component 4 and the plug 1, firstly, align and connect the base 41 with the slot 11 of the plug 1, then apply a pushing force to the base 41 to insert it into the slot 11. When one end of the base 41 is flush with the inner wall of the slot 11, the positioning hole 412 on the base 41 will be precisely aligned with the positioning hole 12 on the slot 11. It should be noted that the positioning hole 412 has an internal thread. Next, a fixing screw is passed through the positioning hole 12 and screwed into the positioning hole 412. The fixing of the base 41 is completed through the threaded connection between the screw and the positioning hole 412.

[0030] The advantages of this design are: the detachable structure of the base 41 and the slot 11 allows for direct replacement of the fixing component 4 when it is damaged; at the same time, the positioning hole 12 and the positioning hole 2 412, when fixed with screws, can effectively prevent the fixing component 4 from detaching from the slot 11 under external force, thus ensuring connection stability.

[0031] Next, the connection between plug 1 and plug 2 is performed: align plug 1 with plug 2 and apply a pushing force to gradually insert plug 1 into plug 2. During insertion, the end of plug 2 will contact the locking head 421 on the rod 42 of the fixing component 4 and apply pressure, forcing the rod 42 to rotate outward around its hinge point with the fixing block 411. At this time, the spring 43 connecting the rod 42 is stretched and in an elastic deformation state. When plug 1 and plug 2 are fully inserted, the pushing force on the locking head 421 disappears, and the rod 42 will rotate inward and reset under the elastic force of the spring 43. The locking head 421 then locks into the edge of the front end of plug 2, thus completing the locking and fixing of plug 1 and plug 2, ensuring a stable connection.

[0032] It should be further explained that both the base 41 and the rod 42 have corresponding slots 44. After plug 1 and plug 2 are engaged, align the locking block 45 with the slots 44 on the base 41 and the rod 42, and push the locking block 45 to fully embed it into the slot 44. Through the limiting action of the locking block 45, the position of the rod 42 can be fixed to prevent it from shaking under the influence of external force, and to avoid failure of the engagement limiting between plug 1 and plug 2.

[0033] To disassemble the plug, first remove the locking blocks 45 on both sides of plug 1 to release the restriction on the rod 42; then press the rods 42 on both sides inward at the same time, so that the rods 42 rotate outward around the hinge point with the fixing block 411, and the locking head 421 disengages from the edge of plug 2, releasing the locking between the two; finally, pull plug 2 out of plug 1 to complete the disassembly.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
