Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable wiring technology, specifically to a staggered T-connection isolation device. Background Technology
[0002] When connecting and fixing low-voltage cables to user wires, cable T-connectors are often used. Cable T-connectors are usually equipped with connection ports that match the internal conductors of the low-voltage cable (if there are 5 conductors inside the low-voltage cable, then there are 5 connection ports on the cable junction box). The 5 conductors are fixedly connected to the user wires by metal fasteners and then clipped into the connection ports for support and fixation.
[0003] Currently, traditional cable T-connectors have the following two problems in use:
[0004] Firstly, the five terminals of current cable T-connectors are usually arranged side by side. When in use, the entire T-connector is erected, and the five terminals are arranged vertically side by side. This results in a wide overall width of the cable T-connector, occupying too much space. When wiring, the outer insulation layer of the low-voltage cable needs to be stripped off, and the five wires inside need to be pulled out and installed side by side in the five terminals of the T-connector. Because the width of the entire cable T-connector is too wide, the five wires need to be pulled out even further to install the five wires side by side in the five terminals. However, the five wires inside the low-voltage cable are twisted together. This structural design makes the wires tightly connected, making it difficult to pull them out. This increases the difficulty of on-site installation.
[0005] Secondly, the five terminals of the current cable T-connectors are basically straight-through structures, and the depth of the terminals (the operating space when branching the wires) is too small. The entire conductor is too close to the inner wall of the terminal, which is not conducive to the subsequent wiring of the user's wires, especially the terminals facing the wall. Utility Model Content
[0006] Therefore, the purpose of this utility model is to overcome the shortcomings of existing cable T-connectors, such as the side-by-side arrangement of the connection ports leading to a larger width of the cable T-connector, which requires a significant amount of wire to be pulled apart when connecting to the user's wires, increasing the difficulty of on-site installation, and the fact that the connection ports are basically straight-through structures with insufficient depth (operating space when branching wires), resulting in the entire wire being too close to the inner wall of the connection port, which is not conducive to subsequent connection of the user's wires.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A staggered T-junction isolation device includes a connector body and a cable mounting section. The cable mounting section includes a rear cable mounting section and a front cable mounting section. The cable mounting sections are recessed on the connector body and have open structures at both ends. The front cable mounting section is staggered from the rear cable mounting section. The bottom wall of the rear cable mounting section and the bottom wall of the front cable mounting section are both inclined. The inclined surface of the rear cable mounting section is either opposite to or in the same direction as the inclined surface of the front cable mounting section.
[0009] In one alternative embodiment, the inclined surface of the cable mounting portion located between two adjacent cable mounting portions on the rear side is arranged in the opposite direction to the inclined surface of the corresponding two adjacent cable mounting portions on the front side.
[0010] In one optional embodiment, there are three cable mounting portions on the rear side and two cable mounting portions on the front side. The two cable mounting portions on the front side are staggered from the three cable mounting portions on the rear side, and the inclined surface of the cable mounting portion located in the middle of the rear side is arranged in the opposite direction to the inclined surface of the two cable mounting portions on the front side.
[0011] In one alternative embodiment, the cable mounting portion is a pre-determined receiving groove, the axial extension length of which is consistent with the height of the connector body.
[0012] In one alternative embodiment, the rear receiving groove is a U-shaped groove, and the front receiving groove is a rectangular groove.
[0013] In one optional embodiment, the rear end face of the connector body is an arched arc surface, and the cable mounting portions on the left and right rear sides are inclined outward from the inside. The front end face of the connector body is an outward convex arc surface, and the two cable mounting portions on the front side are arranged in a figure-eight shape, with the bottom walls of the two front cable mounting portions located above the bottom walls of the cable mounting portions on the left and right rear sides.
[0014] In one optional embodiment, a rear heat dissipation channel is provided between the three rear cable mounting parts and through the connector body, and a front heat dissipation channel is provided between the two front cable mounting parts and on the outer side.
[0015] In one optional embodiment, a cable fastener is fixedly disposed inside the cable mounting portion and fits against the bottom wall of the cable mounting portion. The cable fastener is a flexible C-type clamp.
[0016] Compared with the prior art, the technical solution of this utility model has the following advantages:
[0017] 1. This utility model arranges three cable connection parts on the rear side and two cable connection parts on the front side, so that the cable connection parts on the rear side and the cable connection parts on the front side are superimposed, which greatly reduces the overall width of the T-connector. When using it, the extent to which the five wires are stripped can be reduced, thereby greatly reducing the length of the outer insulation protective layer to be stripped, improving the service life and safety performance of the cable.
[0018] 2. This utility model features an inclined bottom wall for the rear cable connection section and an inclined top wall for the front cable connection section. When the wire is installed into the cable connection section, it will contact the inner wall of one end of the cable connection section (the highest end of the inclined surface), while forming a certain gap with the inner wall of the other end. This facilitates the placement of the user's wire into the gap and connecting it to the wire, greatly improving the convenience of on-site operation and wiring efficiency. Furthermore, the inclined surface of the bottom wall of the rear cable connection section is opposite to (parallel to) the inclined surface of the top wall of the front cable connection section, so that the gaps formed between the wire and the cable connection section in the front and rear cable connection sections are staggered (vertically staggered). In addition to facilitating the connection of the wires distributed in the upper front cable connection section to the user's wire, it also allows the connection points of the wires and the user's wire in the front and rear cable connection sections to be staggered. This disperses the heat dissipation points of the T-connector, greatly improving the heat dissipation efficiency of the T-connector and avoiding malfunctions or spontaneous combustion caused by poor heat dissipation efficiency. This ensures the normal operation of the wire and provides high safety. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0027] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.
[0028] For easier understanding, please refer to Figure 1 and Figure 2 This utility model provides a staggered T-connection isolation device, including a connector body 1 and a cable mounting part; the cable mounting part includes a rear cable mounting part 3 and a front cable mounting part 2. The cable mounting parts are respectively recessed on the connector body 1 and both ends are open structures. The front cable mounting part 2 is staggered from the rear cable mounting part 3. The bottom wall of the rear cable mounting part 3 and the bottom wall of the front cable mounting part 2 are both inclined. The inclined surface of the rear cable mounting part 3 and the inclined surface of the front cable mounting part 2 are either opposite or in the same direction.
[0029] In the above embodiment, the cable mounting part is a pre-determined accommodating groove. The axial extension length of the accommodating groove is consistent with the height of the connector body 1. That is, the accommodating groove penetrates the connector body 1 from top to bottom. Its outer end and both ends are open structures. The rear accommodating groove is a U-shaped groove, and the front accommodating groove is a rectangular groove. The connector body 1 can be integrally molded by injection molding. After the connector body 1 is molded, a cable fixing component is installed in the bottom wall of each corresponding cable mounting part. The two wires to be wired are connected by the action of the cable fixing component. The cable fixing component is a flexible C-type wire clamp. The wire clamp is a conventional copper wire clamp on the market. The main cable and branch cable are attached and fixed together by the action of the pressure clamp. In this invention, the cable fixing component is fixed in the middle of the bottom wall of the cable mounting part.
[0030] The front and rear sides of the cable mounting section are only defined relative to the wall. The rear side is the side closer to the wall, and the front side is the side farther away from the wall (cables are usually arranged close to the wall, so the entire connector body is installed against the wall during installation). The cable mounting section of the entire connector body 1 is vertical (the cable is vertical during installation) and accommodates each conductor within it.
[0031] In the above embodiment, by setting the bottom wall of the rear connection port (cable mounting section) and the top wall of the front connection port (cable mounting section) in an inclined manner, when the main cable (conductor) is installed into the connection port, it will contact the inner wall of one end of the connection port (the highest end of the inclined surface), while forming a certain gap with the inner wall of the other end. This facilitates the insertion of branch cables (user wires) into this gap and connecting them with the conductor (especially in the cable mounting section near the wall), greatly improving the convenience of on-site operation and wiring efficiency; and the inclined surface of the bottom wall of the rear connection port and the top wall of the front connection port... The inclined surfaces of the top wall of the connector are set in opposite directions (parallel to each other), so that the gaps between the main cable and the connector in the upper and lower connectors will be staggered (vertically staggered). In addition to facilitating the connection of the main cable and branch cable in the upper front connector, it also allows the connection points of the main cable and branch cable in the upper and lower connectors to be staggered. This disperses the heat dissipation points of the connector body 1, greatly improving the heat dissipation efficiency of the connector body and avoiding malfunctions or spontaneous combustion caused by poor heat dissipation efficiency of the connector body 1. It can ensure the normal operation of the wires and has a high degree of safety.
[0032] The operating principle of the above embodiment is as follows: During installation, the entire large cable is vertical. First, a section of the outer insulation layer of the large cable is peeled off to expose five main cables of different colors. Then, each of these five main cables is peeled outwards, and the outer layer of the main cable is peeled off to expose the conductors inside. These are then clamped into the C-type clamp of the cable installation part. Since the C-type clamp is installed on the bottom wall of the cable installation part, it will also be arranged at an angle on the inner wall of the cable installation part (the rear wall of the C-type clamp is attached to the inner wall of the cable installation part). When the main cable is installed vertically into the C-type clamp, a gap will be formed between it and the lowest end of the inclined surface of the C-type clamp. Then, the branch cable is inserted into this gap, and then the C-type clamp is tightened with a pressure clamp to fix the main cable and the branch cable together.
[0033] In one alternative implementation, please refer to Figures 3 to 5 The inclined surface of the cable mounting part located between the two adjacent cable mounting parts on the rear side is set in the opposite direction to the inclined surface of the corresponding two adjacent cable mounting parts on the front side.
[0034] Furthermore, there are three rear cable mounting parts 3 and two front cable mounting parts 2. The two front cable mounting parts 2 are staggered from the three rear cable mounting parts 3, and the inclined surface of the rear cable mounting part located in the middle is opposite to the inclined surface of the two front cable mounting parts 2.
[0035] Specifically, the inclined surface of the cable mounting section located in the middle of the rear side is parallel to the inclined surfaces of the two adjacent cable mounting sections on the front side. That is, the highest point of the inclined surface of the rear cable mounting section is opposite to the highest point of the inclined surface of the front cable mounting section (when the highest point of the inclined surface of the rear cable mounting section is at the top, the highest point of the inclined surface of the front cable mounting section will be at the bottom, and vice versa). In other words, when the inclined surface of the rear cable connection section 3 is a forward inclined surface 31, the inclined surface of the front cable connection section 2 is a reverse inclined surface 21, and vice versa. Since the two adjacent cable mounting sections on the front side are relatively close to the rear cable mounting section located between these two adjacent cable mounting sections, when the inclined surfaces of the cable mounting sections with different orientations that are close to each other are reversed, the connection points of the cable mounting sections with different orientations are reversed during the wiring process. This makes it convenient for the main cables that are close to each other to connect the branch cables separately (when the rear cable mounting section connects from the bottom, the front cable mounting section connects from the top).
[0036] In one optional embodiment, the rear end face of the connector body 1 is an arched surface that curves backward, and the cable mounting portions on the left and right rear sides slope outward from the inside. The front end face of the connector body 1 is an outward convex arched surface, and the two front cable mounting portions 2 are arranged in a V-shape, with the bottom walls of the two front cable mounting portions 2 located above the bottom walls of the rear left and right cable mounting portions. This reduces the overall volume of the connector body, thereby saving floor space and facilitating on-site installation.
[0037] In one optional embodiment, a rear heat dissipation channel 5 is provided between the three rear cable mounting parts 3, penetrating the connector body 1. Front heat dissipation channels 4 are also provided between the two front cable mounting parts 2 and on their outer sides (both sides of the arc-shaped surface). By providing heat dissipation channels on one side of each cable mounting part, heat dissipation from the cable mounting parts is accelerated, thereby accelerating heat dissipation from the connector body 1. Heat within the cable mounting parts is less likely to accumulate in the connector body 1, resulting in better heat dissipation and higher safety performance.
[0038] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any changes and modifications made by those skilled in the art to the above embodiments without departing from the spirit and scope of the present invention shall still fall within the scope of protection of the present invention.
