Abstract
Description
Technical Field
[0001] This utility model relates to the field of patch panel devices, and more particularly to a patch panel with adjustable width. Background Technology
[0002] As a key component of a vehicle's automatic control system, automotive wiring harnesses require the use of patch panels for installation. Patch panels play a crucial role in automotive electrical systems, primarily used to organize and support various electrical wiring harnesses within the vehicle. These accessories are typically made of engineering plastics or metals, and their structural design includes multiple orderly arranged channels or through-holes specifically designed for the standardized routing and reliable securing of wires and harnesses.
[0003] Existing patch panels have several technical limitations in their structural design: First, conventional products often use an integral fixed structure to synchronously constrain multiple wire harnesses, or rely on a spring-clamp composite mechanism to position the wire harnesses. However, spring elements are prone to elastic decay under long-term cyclic loads, leading to a decrease in clamping force and the need to replace failed components. Existing devices are mostly fixed, making replacement inconvenient, and external spring structures lack protection and reliability. Second, the clamping units of current patch panels are usually arranged only along a single or dual axis. This linear arrangement results in low three-dimensional space utilization, making it difficult to meet the engineering requirements of high-density wiring in modern automotive electrical systems.
[0004] Therefore, those skilled in the art have provided an adjustable-width patch panel to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable width patch panel. By setting clamping devices in all four directions of the circuit board, the space utilization is greatly improved. By placing the spring inside the circuit board, the spring is effectively protected. By setting the spring and sliding block inside the second locking post, it is easy to replace the spring later.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An adjustable width patch panel includes a mounting frame. A turntable is fixedly mounted in the middle of the upper surface of the base plate of the mounting frame. Guide rods are fixedly mounted on both sides of the upper surface of the base plate of the mounting frame. A lead screw is fixedly mounted on the upper surface of the turntable. A lifting frame is slidably sleeved on the surfaces of the two guide rods. The lower end of the lifting frame is threadedly connected to the lead screw on the upper surface of the turntable. A circuit board is fixedly mounted on one side of the lifting frame. A snap-fit bracket is slidably mounted inside the four ends of the cross-shaped column on one side of the circuit board. A bidirectional lead screw is threadedly sleeved in the cylindrical through hole of each of the four snap-fit brackets opposite to the two snap-fit brackets.
[0008] A second spring is installed inside the cylindrical through hole inside the circuit board. A second snap-fit post is fixedly installed at the other end of the second spring. A first spring is fixedly installed inside the rectangular groove of the second snap-fit post. A sliding block is fixedly installed at the other end of the first spring. A pulling frame is fixedly installed at the other end of the sliding block. A rectangular hole is opened on the surface of the circuit board near the cylindrical through hole. The pulling frame slides in the corresponding rectangular hole.
[0009] Furthermore, multiple first snap-fit posts are uniformly fixed on the surface of the rectangular plates of the four snap-fit brackets facing the circuit board.
[0010] Furthermore, each of the first snap-fit pins snaps into its corresponding second snap-fit pin.
[0011] Furthermore, the clips of the multiple first and second snap-fit posts are all made of natural rubber.
[0012] Furthermore, the smooth portions in the middle of both bidirectional lead screws are rotatably disposed inside the circuit board.
[0013] Furthermore, the circuit board has a rectangular opening slot on one side surface, the rectangular opening slot is connected to a rectangular hole opened on the surface of the circuit board, and the size of the rectangular opening slot is the same as the size of the column on the side of the pull frame facing the sliding block.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model proposes an adjustable-width patch panel. When clamping automotive wiring harnesses, a rotating turntable drives a lifting frame to move along a guide rod via a lead screw, vertically adjusting and positioning the circuit board. Rotating the bidirectional lead screw drives the clamping frames to move towards each other, causing the first clamping post to contact the second clamping post. Pulling the pulling frame causes the second clamping post to retract and compress the spring, separating the two clamping posts and allowing the wiring harness to be inserted. After releasing, the spring rebounds, achieving clamping. The four-way distributed clamping structure significantly improves space utilization.
[0016] 2. This utility model proposes an adjustable-width patch panel. When replacing the second spring, pressing the pull bracket pushes the sliding block to compress the first spring, causing the sliding block to retract into the cylindrical hole of the second locking post. Then, pulling the pull bracket laterally along the rectangular hole allows the spring to be removed from the slot for replacement. The first spring and sliding block inside the second locking post form a quick-disassembly structure, simplifying the maintenance process. Simultaneously, the design of the second spring being built into the circuit board effectively avoids external damage and improves protective performance. Attached Figure Description

[0024] 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.
[0025] Reference Figures 1-5 One embodiment provided by this utility model:
[0026] An adjustable width patch panel includes a mounting frame 1. A turntable 2 is fixedly mounted in the middle of the upper surface of the base plate of the mounting frame 1. Guide rods 4 are fixedly mounted on both sides of the upper surface of the base plate of the mounting frame 1. A lead screw is fixedly mounted on the upper surface of the turntable 2. A lifting frame 3 is slidably sleeved on the surfaces of the two guide rods 4. The lower end of the lifting frame 3 is threadedly connected to the lead screw on the upper surface of the turntable 2. A circuit board 5 is fixedly mounted on one side of the lifting frame 3. A snap-fit bracket 6 is slidably mounted inside the four ends of the cross-shaped column on one side of the circuit board 5. A bidirectional lead screw 7 is threadedly sleeved in the cylindrical through holes of the four snap-fit brackets 6 relative to the two snap-fit brackets 6.
[0027] A second spring 13 is installed inside the cylindrical through hole inside the circuit board 5. A second snap-fit post 10 is fixedly installed at the other end of the second spring 13. A first spring 8 is fixedly installed inside the rectangular groove of the second snap-fit post 10. A sliding block 12 is fixedly installed at the other end of the first spring 8. A pulling frame 11 is fixedly installed at the other end of the sliding block 12. A rectangular hole is opened on the surface of the circuit board 5 near the cylindrical through hole. The pulling frame 11 slides in the corresponding rectangular hole.
[0028] The rectangular plates of the four clip brackets 6 are uniformly fixed with multiple first clip posts 9 on the side of the circuit board 5. The multiple first clip posts 9 are respectively clipped with the corresponding second clip posts 10. The clamps of the multiple first clip posts 9 and the second clip posts 10 are all made of natural rubber. The smooth middle part of the two bidirectional screws 7 is rotatably set inside the circuit board 5. The circuit board 5 has a rectangular opening groove on one side of its surface. The rectangular opening groove is connected to the rectangular hole opened on the surface of the circuit board 5. The size of the rectangular opening groove is the same as the size of the column of the pull bracket 11 facing the sliding block 12.
[0029] Specifically, when clamping the automotive wiring harness, firstly, the turntable 2 is rotated. The lead screw on the upper surface of the turntable 2 drives the lifting frame 3, which is threadedly connected to it, to slide on the surface of the guide rod 4. At the same time, the circuit board 5 on one side of the lifting frame 3 also moves up and down with the lifting frame 3. Rotating the turntable 2 adjusts the position of the lifting frame 3 to facilitate wire installation by the operator. After adjusting the position of the circuit board 5, the bidirectional lead screw 7 is rotated. The bidirectional lead screw 7 drives the two corresponding clamping frames 6 to move relative to each other until the first clamping post 9 on the surface of the clamping frame 6 is pressed against the second clamping post 10 inside the cylindrical hole of the circuit board 5. Then, the pulling frame 11 is pulled, and the second clamping post 10 slides in the cylindrical hole inside the circuit board 5. The second spring 13 is compressed, and the second clamping post 10 separates from the first clamping post 9. The wiring harness is placed between the first clamping post 9 and the second clamping post 10. The pulling frame 11 is released, the second spring 13 returns to its original state, and pushes the second clamping post 10 to fix the wiring harness on the first clamping post 9. By setting clamping devices in four directions on the circuit board 5, the space utilization rate is greatly improved.
[0030] When replacing the second spring 13, press the pull bracket 11. The pull bracket 11 pushes the sliding block 12 to squeeze the first spring 8. The first spring 8 is compressed, and the sliding block 12 slides into the cylindrical hole of the second locking post 10. Then, pull the pull bracket 11 to slide along the corresponding rectangular hole and disengage from the circuit board 5 from the rectangular opening slot. Then, the second spring 13 is taken out for replacement. By setting the first spring 8 and the sliding block 12 in the rectangular slot inside the second locking post 10, it is convenient to replace the second spring 13 later, which facilitates later maintenance. By setting the second spring 13 inside the circuit board 5, the second spring 13 is effectively protected.
[0031] Working Principle: First, rotate the turntable 2. The lead screw on its surface drives the threaded lifting frame 3 to move axially along the guide rod 4, simultaneously causing the circuit board 5 to move vertically. This adjustment mechanism allows operators to accurately position the circuit board 5 according to wiring requirements. After the position is determined, rotate the bidirectional lead screw 7 to drive the two sets of clamping frames 6 to move towards each other, so that the first clamping post 9 and the second clamping post 10 in the cylindrical hole of the circuit board 5 form contact pressure. At this time, pull the pulling frame 11 outward, and the second clamping post 10 retracts along the cylindrical hole and compresses the second spring 13, causing the first and second clamping posts 10 to separate. After placing the wire harness in the gap between them, release the pulling frame 11, and the second spring 13 rebounds, pushing the second clamping post 10 and the first clamping post 9 to clamp the wire harness together. This design significantly optimizes space utilization by evenly distributing clamping units in four directions on the circuit board 5.
[0032] When replacing the second spring 13, press the pull bracket 11 to push the sliding block 12 to compress the first spring 8, causing the sliding block 12 to retract into the cylindrical hole of the second locking post 10. Then, pull the pull bracket 11 horizontally to disengage it from the circuit board 5 through the rectangular slot, allowing the old second spring 13 to be removed for replacement. The rectangular slot inside the second locking post 10 integrates the first spring 8 and the sliding block 12, forming a quick-disassembly structure that greatly simplifies the maintenance process. In addition, the layout of the second spring 13 built into the cavity of the circuit board 5 effectively avoids external mechanical damage and improves protection reliability.
[0033] 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.
