Description

Technical Field

[0001] The present invention relates to the technical field of cable fixing, in particular to a weak-current cable wiring fixing device. Background Art

[0002] Weak-current cables are mainly used to transmit audio, video, data and other signals, such as network signals, TV signals, telephone signals, etc. Since the transmitted signals are weak, they are easily affected by crosstalk between the cables themselves, thus affecting the quality of signal transmission. In order to ensure stable signal transmission, the wiring requirements of weak-current cables are becoming increasingly complex.

[0003] Common low-voltage cable wiring uses auxiliary tools such as nylon cable ties and plastic wire ties to bundle the cables at preset fixed points on the box. Once the number of cables increases or a cable needs to be adjusted, the cable ties need to be cut and re-bundled. This is not only cumbersome but also easy to damage the cables. The use of fixed partitions cannot adjust their layout according to actual conditions, making it difficult to meet actual usage requirements.

[0004] Therefore, we have designed a weak current cable wiring fixture to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a weak-current cable wiring fixture to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides a low-voltage cable wiring fixing device, including a wiring box, the inner side of the wiring box is slidably connected with a first partition, a second partition and a third partition in sequence, the first partition is located above the second partition, the top of the wiring box is slidably sleeved with a pull rod, the bottom of the pull rod is fixedly connected to the first partition, the bottom of the first partition is fixedly connected with a lifting rod, the lifting rods are symmetrically distributed, the lifting rods pass through the second partition and the third partition respectively, the outer wall of the lifting rod is fixedly connected with two blocks, the blocks are respectively abutted against the bottom of the second partition and the third partition, the first partition and the second partition, and the second partition and the third partition are fixedly connected with a separation spring, and the side wall of the wiring box is penetrated by a through hole.

[0007] Furthermore, a return spring is fixedly connected between the top of the first partition and the wiring box, and the return springs are symmetrically distributed.

[0008] Furthermore, latch teeth are fixedly connected around the inner side of the through hole, and the latch teeth are made of silicone rubber.

[0009] Furthermore, copper columns are fixedly connected to both sides of the first partition, the second partition and the third partition, and guide grooves slidably connected to the copper columns are provided on the inner side of the wiring box.

[0010] Furthermore, a transition box is fixedly connected to one side of the wiring box, and the through hole is communicated with the interior of the transition box.

[0011] Furthermore, the wiring box is made of aluminum alloy.

[0012] Furthermore, a copper foil layer is fixedly embedded in the first partition, the second partition and the third partition.

[0013] Furthermore, the outer surface of the guide groove is electroplated with a zinc layer.

[0014] Furthermore, the copper column is tightly matched with and in sliding contact with the galvanized guide groove inside the wiring box, so that the copper foil layer and the galvanized guide groove are electrically connected to each other, forming a complete Faraday cage and reducing the grounding impedance.

[0015] Furthermore, when securing the cable, the pull rod is pulled upward, causing the first partition to move, the lifting rod to rise, and the block to drive the second and third partitions to slide on the lifting rod. The separation spring and return spring are stretched, and the cable is then passed through the through-hole in the side wall of the wiring box. The elastic deformation of the latch teeth initially clamps the cable, and the excess cable can be placed in the transition box. Release the pull rod, the separation spring and return spring recover their deformation, and the first, second, and third partitions move downward, clamping the cable between the partitions. The silicone rubber latch teeth further bite the cable to prevent it from sliding.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The first partition, the second partition and the third partition are connected in a sliding manner through a lifting rod, a stop block and a separation spring. The partition spacing can be adjusted synchronously by pulling the pull rod, which replaces the fixed partition. The spatial layout can be changed within a certain range according to the number and specifications of cables to avoid cable crowding and entanglement. When adding new cables, no additional tools are required. You only need to pull the pull rod to adjust the cable or add the new cable, and loosen the pull rod to fix it. The overall operation is convenient and does not damage the cable.

[0018] 2. By setting up the first partition, the second partition and the third partition, the copper foil layer is fixedly embedded in the inside. The copper foil layer can conduct the current generated by electromagnetic induction, and the edge of the copper foil layer extends to the connection of the copper column. Since the copper column is closely matched with the galvanized guide groove on the inside of the wiring box and is in sliding contact, the copper foil layer and the galvanized guide groove are electrically connected to each other, forming a complete Faraday cage and reducing the grounding impedance.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4 The present invention provides a technical solution: a weak current cable wiring fixing device, including a wiring box 1, the inside of the wiring box 1 is slidably connected with a first partition 5, a second partition 6 and a third partition 15 in sequence, the first partition 5 is located above the second partition 6, and a pull rod 2 is slidably sleeved on the top of the wiring box 1, and the bottom of the pull rod 2 is fixedly connected to the first partition 5, and the bottom of the first partition 5 is fixedly connected to a lifting rod 9, which is symmetrically distributed. The lifting rods 9 pass through the second partition 6 and the third partition 15 respectively, and two blocks 10 are fixedly connected to the outer wall of the lifting rod 9, which abut against the bottom of the second partition 6 and the third partition 15 respectively. A separation spring 8 is fixedly connected between the first partition 5 and the second partition 6, and between the second partition 6 and the third partition 15. The separation spring 8 plays a buffering and resetting role between the partitions, and a through hole 4 is opened through the side wall of the wiring box 1. The through hole 4 is used for cables to enter and exit the wiring box 1, providing a channel for the cables.

[0026] During the specific implementation, first hold the pull rod 2 and pull it upward to drive the first partition 5 to move upward. At this time, the lifting rod 9 at the bottom of the first partition 5 will rise accordingly, and the block 10 will cause the second partition 6 and the third partition 15 to slide upward on the lifting rod 9. The separation spring 8 between the first partition 5 and the second partition 6, and the second partition 6 and the third partition 15 is stretched; pass the cable through the through hole 4 on the side wall of the wiring box 1, and then release the pull rod 2. Under the resetting action of the separation spring 8, the first partition 5, the second partition 6 and the third partition 15 move downward to clamp the cable between the partitions.

[0027] See Figures 1-4As shown, a reset spring 7 is fixedly connected between the top of the first partition 5 and the wiring box 1. The reset springs 7 are symmetrically distributed. When the pull rod 2 is pulled upward to drive the first partition 5 to rise, the reset spring 7 is stretched to generate elastic force. After the pull rod 2 is released, the reset spring 7 relies on its own elastic force to provide a downward pulling force for the first partition 5, prompting the first partition 5, the second partition 6 and the third partition 15 to reset, thereby clamping the cable and improving the stability of the fixation.

[0028] See Figure 3-Figure 4 , there are fixedly connected with latch teeth 13 around the inner side of the through hole 4. The latch teeth 13 are made of silicone rubber and are elastic. When the cable passes through the through hole 4, the silicone rubber latch teeth 13 clamp the cable through elastic deformation to prevent sliding. A transition box 3 is fixedly connected to one side of the wiring box 1. The through hole 4 is connected to the inside of the transition box 3. The transition box 3 provides a buffer space for pre-wiring to avoid right-angle bending, which is convenient for cable arrangement inside and outside the wiring box 1.

[0029] See Figure 1-Figure 2 Copper pillars 12 are fixedly connected on both sides of the first partition 5, the second partition 6 and the third partition 15. A guide groove 11 is provided on the inside of the wiring box 1 to be slidably connected to the copper pillar 12. The outer surface of the guide groove 11 is electroplated with a zinc layer, which forms a continuous shielding body with the copper foil layer 14 to block the intrusion of external electromagnetic waves and prevent interference signals from being superimposed on the cable transmission signal.

[0030] See Figure 1-Figure 2 The wiring box 1 is made of aluminum alloy. A copper foil layer 14 is fixedly embedded inside the first partition 5, the second partition 6 and the third partition 15. The copper foil layer 14 can conduct the current generated by electromagnetic induction, and the edge of the copper foil layer 14 extends to the connection of the copper column 12. Since the copper column 12 is tightly matched and in sliding contact with the galvanized guide groove 11 on the inside of the wiring box 1, the copper foil layer 14 and the galvanized guide groove 11 are electrically connected to each other, forming a complete Faraday cage and reducing the grounding impedance.

[0031] Working principle:

[0032] When securing the cable, hold the pull rod 2 and pull it upward, the first partition 5 moves accordingly, the lifting rod 9 rises, the block 10 drives the second partition 6 and the third partition 15 to slide on the lifting rod 9, the separation spring 8 and the return spring 7 are stretched, and then the cable is passed through the through hole 4 on the side wall of the wiring box 1. The clamping teeth 13 initially clamp the cable due to elastic deformation, and the excess cable can be placed in the transition box 3. Release the pull rod 2, the separation spring 8 and the return spring 7 recover their deformation, and the first partition 5, the second partition 6, and the third partition 15 move downward, clamping the cable between the partitions. The silicone rubber clamping teeth 13 further bite the cable to prevent it from sliding.

[0033] At this time, the aluminum alloy shell of the wiring box 1, the first partition 5, the second partition 6 and the copper foil layer 14 in the third partition 15, together with the copper column 12 and the galvanized guide groove 11, form a continuous shielding body and a complete Faraday cage, blocking external electromagnetic waves, reducing grounding impedance, and completing the wiring fixation and anti-interference processing of the weak current cable.
