Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and specifically relates to a connector with a wire harness structure. Background Technology

[0002] With the increasing integration and diversification of electronic devices, wire harness management has become a core issue affecting system reliability, maintenance efficiency, and space utilization. Long-term vibration can cause micro-gaps between the wire harness and connector terminals, leading to increased contact resistance or even open circuits. Repeated bending can cause conductor fatigue fracture. Traditional connectors often rely on housing clips or external cable ties to secure the wire harness, but these methods have drawbacks such as uncontrollable contact pressure, poor adaptability, and difficult maintenance. Cable ties that are too tight can damage the cable insulation layer, while those that are too loose will fall off due to vibration. Furthermore, removing cable ties is very troublesome and requires the assistance of scissors, which can easily damage the cable. Utility Model Content

[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connector with a cable bundle structure, which aims to solve the problems of existing technology where cable ties are too tight and easily damage the cable insulation layer, or too loose and fall off due to vibration, and the removal of cable ties is very troublesome and requires the assistance of scissors, which may easily damage the cable.

[0004] (2) Technical solution To address the aforementioned technical problems, this utility model provides a connector with a wire harness structure, comprising a connector body, a cover plate, and an auxiliary frame. The connector body has a cover plate fixed to its upper and lower surfaces. An inner sliding groove is horizontally formed on the side wall of the cover plate, and an inner slider is slidably mounted inside the inner sliding groove. An auxiliary frame is connected to the surface of the inner slider. The auxiliary frame includes a rod portion and a plate portion. The rod portion is symmetrically distributed at four corners, and a wire routing groove is formed inside the plate portion. Clamping wheels and fixing wheels are respectively provided on the upper and lower surfaces of the wire routing groove. The clamping wheels and fixing wheels are horizontally spaced apart, and an inverted U-shaped drive rod is rotatably connected to the end of each clamping wheel. This design allows for controllable clamping force on the wire harness, avoiding cable damage or loosening caused by uncontrollable pressure from traditional cable ties. Simultaneously, real-time fine-tuning compensates for deformation of the wire harness due to vibration or temperature changes, ensuring stable contact resistance, effectively reducing the risk of open circuits and extending the lifespan of the wire harness.

[0005] Optionally, the drive rod slides against the inner surface of the auxiliary frame, and an adjusting screw is vertically threadedly connected to the center of the drive rod.

[0006] Optionally, a fixing block is rotatably connected to the bottom of the adjusting screw, and the fixing block is fixedly connected to the auxiliary frame.

[0007] Optionally, the upper surface of the cover plate is provided with slots spaced apart.

[0008] Optionally, the card slot is connected to the inner slide groove, and a buckle is installed on the surface of the inner slide block facing the card slot.

[0009] Optionally, the bottom of the buckle extends into the inner slider, and the inner slider has an installation groove for installing the buckle. A spring is vertically installed in the installation groove, and the spring is fixedly connected to the buckle.

[0010] Optionally, mounting blocks are rotatably connected to both ends of the fixed wheel, and the mounting blocks are fixedly connected to the auxiliary frame.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a modular sliding mechanism to support the auxiliary frame to be flexibly positioned and locked along the inner sliding groove. The elastic cooperation between the buckle and the slot enables tool-free quick assembly and disassembly. It not only meets the space optimization requirements for fixing multiple wire harnesses in different areas, but also greatly improves the maintenance efficiency in confined spaces. The clamping wheel is driven by an adjusting screw, which can control the clamping force on the wire harness and avoid cable damage or loosening caused by the uncontrollable pressure of traditional cable ties. At the same time, it compensates for the deformation of the wire harness caused by vibration or temperature change through real-time fine adjustment, ensuring stable contact resistance, effectively reducing the risk of circuit breakage and extending the life of the wire harness. The clamping wheel and the fixed wheel, together with the stable support of the inverted U-shaped drive rod, improve the vibration resistance of the connector. Attached Figure Description

[0015] 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.

[0016] This specific embodiment is a connector with a wire harness structure, and its structural schematic diagram is shown below. Figure 1 As shown, it includes a connector body 1, a cover plate 7 and an auxiliary frame 3. The upper surface and the bottom surface of the connector body 1 are both fixed with the cover plate 7. The side wall of the cover plate 7 is horizontally provided with an inner sliding groove 6, and an inner slider 2 is slidably installed inside the inner sliding groove 6. Reference Figure 2 , Figure 4 An auxiliary frame 3 is connected to the surface of the inner slider 2. The auxiliary frame 3 includes a rod and a plate. The rod is symmetrically distributed at the four corners, and the plate has a wiring groove 14 inside. The upper and lower surfaces of the wiring groove 14 are respectively provided with clamping wheels 10 and fixed wheels 15, which are horizontally spaced apart. The end of the clamping wheel 10 is rotatably connected to a drive rod 9 with an inverted U-shaped structure. The drive rod 9 slides and fits against the inner surface of the auxiliary frame 3. An adjusting screw 8 is vertically threaded and rotatably connected to the center of the drive rod 9. A fixing block 11 is rotatably connected to the bottom of the adjusting screw 8, and the fixing block 11 is fixedly connected to the auxiliary frame 3. The upper surface of the cover plate 7 has slots 4 spaced apart. The slots 4 communicate with the inner sliding groove 6, and a buckle 5 is installed on the surface of the inner slider 2 facing the slot 4.

[0017] Reference Figure 3 The bottom of the buckle 5 passes through the inner slider 2. The inner slider 2 has a mounting groove 13 for mounting the buckle 5. A spring 12 is vertically mounted in the mounting groove 13 and is fixedly connected to the buckle 5. Mounting blocks are rotatably connected to both ends of the fixed wheel 15 and are fixedly connected to the auxiliary frame 3.

[0018] Working principle: By pushing the inner slider 2 to slide along the inner groove 6 on the side wall of the cover plate 7, the auxiliary frame 3 is adjusted to the target position. When the auxiliary frame 3 moves above the preset slot 4, the buckle 5 on the inner slider 2 pops out under the elastic force of the spring 12 and locks into the slot 4, realizing the quick positioning and locking of the auxiliary frame 3. When the position needs to be readjusted, press the buckle 5 to disengage it from the slot 4, which will unlock the auxiliary frame 3 and allow it to slide.

[0019] The wire harness passes through the cable routing groove 14 on the plate of the auxiliary frame 3, and fixed wheels 15 and adjustable clamping wheels 10 are respectively provided on its upper and lower surfaces. By rotating the adjusting screw 8 on the drive rod 9, the drive rod 9 slides vertically along the inner surface of the auxiliary frame 3, driving the clamping wheels 10 to press the wire harness towards the fixed wheels 15. The fixed wheels 15 are fixedly connected to the auxiliary frame 3 through mounting blocks at both ends, providing a stable reaction force to ensure that the clamping wheels 10 apply uniform pressure to the wire harness and avoid local over- or under-pressure.

[0020] When vibration or temperature changes cause slight variations in the wire harness diameter, the user can adjust the position of the clamping wheel 10 in real time using the fine-tuning screw 8 to compensate for wire harness deformation and maintain optimal contact pressure. The inverted U-shaped drive rod 9 slides against the inner surface of the auxiliary frame 3, ensuring the stability of the drive rod 9 during adjustment and preventing the clamping wheel 10 from shifting.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
