Description

Technical Field

[0001] The utility model relates to the technical field of cable wiring, in particular to an assembled low-voltage cable branch converter. Background Technique

[0002] In the connection structure of conductive cables, branch wiring often occurs (commonly known as T-shaped wiring), that is, it is necessary to separately connect external branch cables to five branch cables inside the main cable. When connecting the external branch cable to the main cable, usually first peel off the skin of the main cable to expose the internal branch cables, then connect the conductors of the external branch cables to the conductors of different branch cables inside the main cable respectively, and then respectively clamp the connection parts of different branch cables into different wiring ports of the cable converter for clamping and fixing.

[0003] At present, the cable converters on the market have a cylindrical structure and a square structure. The wiring ports of the square structure cable converter are arranged side by side, that is, the five branch cables are arranged side by side when connected. The wiring ports of the cylindrical structure cable converter are arranged in a ring shape, that is, multiple partition plates are circumferentially and equally spaced on the outer peripheral wall of the cable converter, and multiple wiring ports are respectively formed between adjacent partition plates. The multiple wiring ports enclose to form a ring, so that the five branch cables are arranged in a spindle shape on the cable converter. Compared with using a square converter to arrange the five branch cables side by side, when using a cylindrical converter to arrange the five branch cables in a spindle shape, the pulling amplitude of the five branch cables can be reduced, so there is no need to largely peel off the protective layer outside the main cable, which can reduce the damage to the main cable. Therefore, the cylindrical structure cable converter is more and more widely promoted.

[0004] However, in the above-mentioned cylindrical structure cable converter, since the external partition plates are fixed, when using it to clamp the connection parts of the cables into each wiring port, except for one branch cable that is directly clamped into the wiring port during installation, the remaining branch cables all need to be pulled out one by one by the staff around the partition plates and then clamped into the wiring ports, resulting in a certain amount of labor and installation time, and the installation is more troublesome. When wiring multiple cable converters, it will lead to a decrease in work efficiency and affect the work progress. Content of the Utility Model

[0005] Therefore, the purpose of the utility model is to provide an assembled low-voltage cable branch converter, which is more convenient to install during use, can save a certain amount of labor cost, and improve work efficiency.

Among them, at least one assembly body is detachably connected to the outer peripheral wall of the core body, and the notch formed by enclosing between adjacent assembly bodies is adapted to accommodate the connection part of the main cable and the branch cable that is externally snapped into it.

[0008] In an alternative embodiment, the height of the assembly body is the same as the height of the core body, and the distance between the two side walls of the assembly body is tapered from the outer peripheral wall of the assembly body to the outer peripheral wall of the core body.

[0010] In an alternative embodiment, three adjacent assembly bodies among the five assembly bodies are detachably connected to the core body.

[0011] In an alternative embodiment, the assembly body is detachably connected to the outer peripheral wall of the core body through a sliding structure. The sliding assembly includes a slider and a chute adapted to the slider; the slider is axially connected to the outer peripheral wall of the core body and / or the slider is axially connected to the side surface of the assembly body close to the core body along the axial direction of the assembly body.

[0012] In an alternative embodiment, the distance between the two side walls of the slider is tapered from outside to inside, and the diameter of the chute is diffusely arranged corresponding to the slider from outside to inside.

[0013] In an alternative embodiment, a fastening channel is radially and penetratingly formed on the assembly from the outer peripheral wall of the assembly to the chute direction of the assembly. A fastening hole is recessed in the slider on the core body corresponding to the fastening channel. A fastening screw is connected to the fastening channel and the fastening hole, and is adapted to pass through the fastening channel and the fastening hole to be fixed, so as to fasten the assembly slid onto the core body to the core body.

[0014] In an alternative embodiment, the assembly is detachably connected to the outer peripheral wall of the core body through a mortise and tenon structure.

[0015] In an alternative embodiment, the two end faces of the bottom wall of the notch formed by enclosing two adjacent assemblies are respectively beveled grooves, which are adapted to contract and gather all the cables located outside the notch towards the central axis of the core body, so as to attach the connection part of the main cable and the branch cable in the notch to the bottom wall of the notch.

[0024] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0025] The following will be combined with Figures 1 to 3 to describe the embodiments of the present utility model.

[0026] This embodiment discloses an assembled low-voltage cable branch converter, which includes a core body 1 and an assembly body 2; the core body 1 is of a tubular structure; there are multiple assembly bodies 2, and the multiple assembly bodies 2 are connected to the outer peripheral wall of the core body 1 at equal intervals along the circumferential direction of the core body 1. Among them, at least one of the assembly bodies 2 is detachably connected to the outer peripheral wall of the core body 1, and the notch 3 formed by enclosing between adjacent assembly bodies 2 is adapted to accommodate the connection part of the main cable and the branch cable that is externally clamped into it.

[0027] In the above embodiment, by detachably installing the assembly body 2 on the core body 1, the assembly body 2 can be taken outwards during use, and after the branch cable is attached to the outer wall of the core body 1, the assembly body 2 is assembled on both sides of the branch cable. There is no need to pull the branch cable outwards too much to install it on the converter, and the installation is relatively convenient, which can save a certain amount of labor time and cost and improve the installation efficiency.

[0028] In this embodiment, the outer peripheral wall of the core body 1 is annular, and a heat dissipation channel is axially penetrated through the inner wall of the core body 1, and an air flow can be formed therein to take away the heat generated by the cable connection part attached to the outer wall of the core body 1 together, improving the heat dissipation effect. The assembly bodies 2 are arranged at equal intervals along the outer peripheral wall of the core body 1. Thus, a notch 3 with openings at both ends can be formed between the adjacent assembly bodies 2 and the outer peripheral wall of the core body 1. This notch 3 is used to accommodate the connection parts of each branch cable of the main cable and the external cable, and the adjacent two branch cables are separated by the assembly body 2. When wiring, first disassemble the assembly body 2 from the outer wall of the core body 1, attach the connection part of the branch cable to the outer peripheral wall of the core body 1 between two adjacent parts for installing the assembly body 2, and then arrange the assembly body 2 on both sides of the branch cable and connect it to the core body 1 to form an integrated body.

[0029] In an alternative embodiment, the height of the assembly 2 is the same as the height of the core 1. The distance between the two side walls of the assembly 2 is tapered from the outer peripheral wall of the assembly 2 towards the outer peripheral wall of the core 1. The tapered ends of the two side walls of the assembly 2 are respectively connected radially with splicing plates 7. The front and rear end faces of the splicing plates 7 are both arc-shaped structures. Among them, the radian of the rear end face close to the core 1 is the same as the radian of the outer peripheral surface of the core 1, and the radian of the front end face far from the core 1 is symmetrically arranged with the radian of the rear end face. The side walls of two adjacent splicing plates 7 far from the assembly 2 are closely attached to form the bottom wall of the arc-shaped notch 3.

[0030] In the above embodiment, the transverse section of the assembly 2 is fan-shaped, that is, the two outer side walls of the assembly 2 gradually approach each other from the outside to the inside. The diameter of the notch 3 formed by enclosing between adjacent assemblies 2 is tapered from the outside to the inside, which is convenient for clamping the connecting part of the branch cable from the outside to the inside, and the stabilizing effect is better. Through the splicing action of the two splicing plates 7, on the one hand, the assembly 2 can be attached and connected to the core 1 during splicing, and on the other hand, the inner wall of the notch 3 can be arc-shaped, so that the wiring part of the branch cable fits more closely with the bottom wall of the notch 3 and is not easily separated from the notch 3.

[0031] In an alternative embodiment, there are five assemblies 2. At least two adjacent assemblies 2 among the five assemblies 2 are detachably connected to the core 1. That is, all five assemblies 2 can be set to be detachably connected to the core 1, or four adjacent assemblies 2 among the five assemblies 2 can be set to be detachably connected to the core 1, and the remaining one assembly 2 is fixedly connected to the core 1. Or three adjacent assemblies 2 among the five assemblies 2 can be set to be detachably connected to the core 1, and the remaining two adjacent assemblies 2 are fixedly connected to the core 1. Preferably, three assemblies 2 are detachably connected to the core 1, and the remaining two assemblies 2 are fixedly connected to the core 1.

[0032] After the three assemblies 2 are disassembled, only one fixed wiring slot 3 is left, which is then passed through the assembly 2 and then stuck into the other slot 3, which requires a certain amount of labor. When the three assemblies 2 are disassembled, only one fixed wiring slot 3 is left, which is then passed through the assembly 2 and then stuck into the other slot 3, which requires a certain amount of labor. When the three assemblies 2 are disassembled, only one fixed wiring slot 3 is left, which is then passed through the assembly 2 and then stuck into the other slot 3, which requires a certain amount of labor. When the three assemblies 2 are disassembled, only one fixed wiring slot 3 is left, which is then stuck to one of the branch cables when in use. The remaining branch cables do not need to be pulled out too far and can be directly fitted to the outer wall of the core 1, and then the assemblies 2 are assembled one by one on both sides, which can save a certain amount of labor.

[0033] In an optional embodiment, the assembly body 2 is detachably connected to the outer peripheral wall of the core body 1 via a sliding structure, and the sliding assembly includes a slider 8 and a sliding groove 9 adapted to the slider 8 .

[0034] The slider 8 is connected to the outer peripheral wall of the core 1 along the axial direction of the core 1. The slide groove 9 is formed on the side of the assembly 2 close to the core 1 along the axial direction of the assembly 2, corresponding to the slider 8. The slider 8 is adapted to fit with the slide groove 9 to slidably connect the assembly 2 to the outer peripheral wall of the core 1. The slider 8 and the slide groove 9 facilitate the installation and removal of the assembly 2 from the core 1.

[0035] Preferably, the distance between the two side walls of the slider 8 is tapered from the outside to the inside, and the diameter of the chute 9 is arranged to expand from the outside to the inside to correspond to the slider 8. The cooperation between the tapered slider 8 and the expanding chute 9 allows the assembly 2 to be firmly connected to the core 1 and is not easily dislodged when pushed outward by a horizontal external force.

[0036] Further, a fastening channel 5 is radially and penetratingly formed on the assembly 2 from the outer peripheral wall of the assembly 2 to the sliding groove 9 of the assembly 2. A fastening hole 6 is recessed on the slider 8 of the core body 1 corresponding to the fastening channel 5. A fastening screw is connected to the fastening channel 5 and the fastening hole 6 and is adapted to pass through the fastening channel 5 and the fastening hole 6 for fixation to fasten the assembly 2 slid onto the core body 1 to the core body 1. Through the action of the fastening screw, the assembly 2 and the core body 1 can be fixedly installed together, preventing looseness between the slider 8 and the sliding groove 9 and avoiding the separation of the assembly 2 from the core body 1, which affects the use and improves the stability of the entire converter during use. During specific use, first install the assembly 2 onto the core body 1, and then fasten the fastening screw from the fastening channel 5 into the fastening hole 6 to connect and integrate the assembly 2 and the core body 1. When disassembling, simply screw out the fastening screw from the fastening hole 6.

[0037] In an alternative embodiment, the assembly 2 is detachably connected to the outer peripheral wall of the core body 1 through a mortise and tenon structure. Through the mortise and tenon structure, it is convenient to directly snap the assembly 2 onto the outer wall of the core body 1 from the outside, and the installation is relatively convenient. Specifically, the mortise and tenon structure includes a tenon and a mortise. The tenon has a frustum-shaped structure, and its two side surfaces are inclined. The mortise is a groove that matches the tenon. The tenon can be connected to the side wall of the assembly 2 close to the core body 1, and the mortise is correspondingly formed on the outer peripheral wall of the core body 1. During use, directly align the tenon with the mortise and snap it in to fix the assembly 2 on the core body 1. Similarly, reversing the positions of the tenon and the mortise will also work.

[0038] In other embodiments, other structures that enable the detachable connection between the assembly 2 and the core body 1 can also be adopted, and all the structures adopted are within the scope protected by this application, and they are not listed one by one here.

[0039] In an alternative embodiment, the two end faces of the bottom wall of the notch 3 formed by enclosing two adjacent assemblies 2 are respectively beveled grooves 4, which are adapted to contract and gather all the cables located outside the notch 3 towards the central axis direction of the core body 1 so as to attach the connection part of the main cable and the branch cable in the notch 3 to the bottom wall of the notch 3.

[0040] In this embodiment, by setting the two end faces of the bottom wall of the notch 3 as beveled grooves 4, the branch cables in the main cable can be in a contracted and gathered state when contacting the two ends of the core body 1. As a result, the connection part of the branch cables will be attached towards the bottom wall of the notch 3, causing multiple branch cables to contract and gather towards the central axis direction of the core body 1, preventing the situation where the connection parts of the cables protrude and spread outwards, resulting in poor fixing effects, and improving the stability of the connection of the connection parts of the cables.

[0041] In the above embodiment, two ends of the splicing plate 7 of the assembly 2 are respectively provided with two inclined upward slopes, and the bottom wall of the slope is arc-shaped. When the two splicing plates 7 are spliced together, an inclined upward slope with an arc-shaped bottom wall can be formed. When the cable abuts against the slope, the mutual fit between the cable and the core 1 can be improved, so that the cable fits tightly on the core 1. When the branch cable is wired on the converter, the whole is spindle-shaped, that is, when wiring, only the outer layer of part of the main cable is peeled off to expose the five branch cables that are bonded together. Then the branch cable is separated and wired with the external cable and then fixed to the converter. Since the five branch cables are spindle-shaped after separation, their two ends form a contracted and gathered shape, and the cable has a certain hardness. Therefore, when the two ends of the cable abutting the core 1 are at right angles, that is, vertical surfaces, the wiring parts in the two ends of the cable abutting, that is, the wiring parts located in the wiring slot 3 of the core 1 will be tilted outward, resulting in poor stability.

[0042] Although the present invention has been described using the above preferred embodiments, they are not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
