Description

Technical Field

[0001] The invention relates to the technical field of cable installation engineering, in particular to an inner-locking plum blossom-shaped diverter. Background Art

[0002] In the process of power transmission and distribution, the main cable is mainly used for power transmission. The main cable contains multiple branch cables. When power needs to be distributed to various electrical equipment, the insulation layer on the outside of the main cable needs to be peeled off, and the branch cables inside need to be connected and fixed to the wires of each user who needs electricity through the function of cable connectors, so as to achieve the purpose of power distribution.

[0003] When performing power distribution wiring, it is necessary to use cable connectors to connect and fix the branch cables and the wires of each device. Traditional cable connectors are usually equipped with five wiring ports, each of which is equipped with a flexible C-shaped wire clamp. After stripping the outer insulation layer of the five branch cables and the insulation layer of the user wires, they are correspondingly clipped into the C-shaped wire clamp of each wiring port. After tightening the wire clamp with the help of auxiliary tools, the two cables can be fitted and fixed together.

[0004] According to the wiring occasion, it is divided into outdoor wiring and indoor wiring. Outdoor wiring has a larger operating space, so it is more convenient to use cable connectors for wiring. However, when wiring indoors, especially when wiring user wires in weak current wells (also called cable shafts, which are channels in high-rise or multi-story buildings used to lay vertical trunk communication cables, etc.), the space inside the weak current well is relatively small, there are many lines inside, and the space left for staff to operate is limited. In addition, the main cables are generally distributed vertically against the wall. It is difficult to use traditional cable connectors to connect and fix the five branch cables to the user wires, especially the cable connector ports facing the wall. It is time-consuming and labor-intensive, which greatly reduces the work efficiency of the staff. Summary of the Invention

[0013] In an optional embodiment, the diameter of the guide lock groove is gradually reduced from the bottom wall toward the groove opening, the length of the lock bar is the same as the length of the guide lock groove, and the outer diameter of the lock bar is gradually reduced from the outside toward the end face of the wiring base.

[0014] In an optional embodiment, a limiting plate is provided on one end of the guide lock groove, which is suitable for limiting and fixing the upper wiring base that slides vertically onto the lower wiring base.

[0015] In an optional embodiment, the wiring base is arranged in a fan shape, and there are five wiring bases. The five wiring bases are arranged circumferentially with equal angles between each other, and the five wiring bases are arranged circumferentially with the insulating connector to form a plum blossom-shaped diverter.

DETAILED DESCRIPTION

[0029] In order to help those skilled in the art better understand the present invention, 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 those skilled in the art without creative work are within the scope of protection of this application.

[0030] The following combination Figures 1 to 5 , describing embodiments of the present invention.

[0031] An internally locked plum blossom-shaped shunt comprises a branch wiring unit; there are multiple branch wiring units, which are arranged at equal intervals around the circumference, and the branch wiring unit comprises a wiring base 1, on the end surface of the wiring base 1, external wiring ports 301 and internal wiring ports 302 are respectively provided at intervals along the axial direction of the wiring base 1, and the external wiring port 301 is an openable structure. A first locking hole is provided between the outer end of the wiring base 1 and the external wiring port 301, a second locking hole is provided between the external wiring port 301 and the internal wiring port 302, and a third locking hole is provided between the inner end of the wiring base 1 and the internal wiring port 302. The first locking hole, the second locking hole and the third locking hole are all coaxially arranged with the wiring base.

[0032] Optionally, the external wiring port 301 and the internal wiring port 302 are both circular ports, suitable for fitting with the surface of the wire, the inner diameter of the external wiring port 301 is greater than or equal to the inner diameter of the internal wiring port 302, and the external wiring port 301 and the internal wiring port 302 are coaxially arranged with the wiring base 1.

[0033] Furthermore, the first locking hole, the second locking hole and the third locking hole are all threaded holes and have the same hole diameter, so that the locking bolts of each hole can be adapted during later use.

[0034] Furthermore, the first locking hole, the second locking hole and the third locking hole are two or three respectively, and multiple locking holes can be used to tighten cables with different outer diameters in the external wiring port 301 and the internal wiring port 302. For example, when the outer diameter of the incoming cable is small, the cable can be tightened through only one locking hole. When the outer diameter of the incoming cable is medium, it needs to be tightened through two locking holes. When the outer diameter of the incoming cable is large, it needs to be tightened through three locking holes. Therefore, the fastening holes can be set to three, so that they can be used selectively according to the wire diameter when in use.

[0035] Furthermore, it also includes an insulating connector 5, which is also arranged in a plum blossom shape and is composed of multiple insulating blocks 501 arranged circumferentially at intervals. A mounting opening 502 is formed between adjacent insulating blocks 501. The inner diameter of the mounting opening 502 can be designed to be slightly larger than the outer diameter of the wiring base 1, so that the wiring base 1 can be just clamped therein. The wiring base 1 is clamped therein by the function of the mounting opening 502, thereby multiple wiring bases 1 can be assembled together with the help of the connector. After being assembled together, a plum blossom-like structure is formed, in which each insulating block Two limiting plates 503 are circumferentially connected to both sides of the rear end of 501 along the direction of the curved surface of the insulating block 501. The limiting plates 503 partially block the opening outside the mounting port 502 to prevent the wiring base 1 from falling down when the connector is used vertically. A heat dissipation channel 504 is also provided on each insulating block 501 to facilitate the dissipation of heat conducted from the wiring base 1 on the insulating block 501. Furthermore, a heat conduction channel connecting the mounting port 502 and the heat dissipation channel 504 can be provided horizontally on the insulating block 501.

[0036] In the above embodiment, the wiring base 1 has a certain length and thickness, and the wiring base 1 is made of copper or other benign conductive materials, so that mutual conductivity can be achieved between the branch cables and user wires separately fixed thereon. In the process of making the shunt, the wiring base 1 is first made separately, and then multiple wiring bases 1 are circumferentially connected through the insulating connector 5 with independent mounting openings 501. The insulating connector 5 has mounting openings 501 that match the wiring base 1 on the circumference, and adjacent mounting openings 501 are arranged at intervals to separate adjacent wiring bases 1 from each other. After being assembled together, a plum blossom-shaped shunt can be formed. Multiple wiring bases 1 respectively form a circular shunt on the circumference, and adjacent wiring bases 1 form an equidistant angle, which is the spacing between adjacent mounting openings of the insulating connector. A single wiring base 1 can also be used separately. When used separately, it can be wrapped with a protective box. When used in combination with multiple wiring bases 1, it needs to be installed on the insulating connector and fixed before use.

[0037] On the end face of the wiring base 1, an external wiring port 301 and an internal wiring port 302 are spaced apart from top to bottom along the direction of the symmetry axis of the wiring base 1. There is a preset distance between the external wiring port 301 and the internal wiring port 302. The external wiring port 301 is located near the top of the wiring base 1 and is used to install and fix the branch cable in the main cable. The internal wiring port 302 is located near the bottom of the wiring base 1 and is used to install and fix the user wires. The branch cable and the user wires can be operated separately through the external wiring port 301 and the internal wiring port 302. A first through hole is opened between the upper end face of the wiring base 1 and the external wiring port 301 along the direction of the symmetry axis of the wiring base 1. A threaded hole 201 is provided, and a second threaded hole 202 is provided in the spacing between the external wiring port 301 and the internal wiring port 302 to connect the external wiring port 301 and the internal wiring port 302. A third threaded hole 203 is provided on the lower end surface of the wiring base 1 to pass through the internal wiring port 302. Through the function of the first threaded hole 201, a locking bolt can be inserted from the outside to fix the branch cable in the external wiring port 301. Through the function of the second threaded hole 202, the wires in the external wiring port 301 or the internal wiring port 302 can be fixed in both directions respectively. And through the function of the third threaded hole 203, a locking bolt can be inserted from the outside to fix the user wire in the internal wiring port 302.

[0038] It should be noted that the "upper end" and "lower end" of the wiring base mentioned above refer to the orientation when the entire diverter is in a vertical position. When in use, the diverter is in a horizontal structure.

[0039] In the above embodiment, during use, different cable installation sequences can be flexibly performed for the wiring base 1 at different locations (close to the wall or away from the wall), and the bolts therein can be moved forward or reversely through the second threaded hole 202, so that the wiring port where the cable is installed first can be flexibly selected for cable tightening, which is convenient for on-site workers to fix cables that are relatively difficult to install at the back, and can also facilitate locking and fixing of wires located at the front, greatly reducing the difficulty of wiring, shortening working time, and improving work efficiency.

[0040] In actual use of the above embodiment, since the diverter is a circular structure composed of multiple wiring bases 1, when in use, part of the wiring base 1 is close to the wall (located on the back where the staff operates) and part of the wiring base 1 is located away from the wall (located on the front where the staff operates). In addition, since the external wiring port 301 is located at the upper part of the wiring base 1 (that is, at the outer ring position of the diverter) and the internal wiring port 302 is located at the lower part of the wiring base 1 (that is, at the outer ring position of the diverter), the external wiring port 301 of the wiring base 1 close to the wall will be the back wiring port relative to the internal wiring port 302 (staff). In this wiring base, When wiring on 1, first install the branch cable into the external wiring port 301. At this time, the first threaded hole 201 at the outer end of the external wiring port 301 will not function. You can only use the L-shaped tightening auxiliary tool to pass through the third threaded hole 203 and the internal wiring port 302 to move the locking bolt in the second threaded hole 202 into the external wiring port 301 to lock and fix the branch cable. After fixing it, pass the user wire into the internal wiring port 302. Since the third threaded hole 203 is facing the staff, it is convenient to fix the user wire through the third threaded hole 203, thereby completing the wiring fixation function of the wiring base 1 located close to (adhering to) the wall.

[0041] Similarly, when wiring the portion of the wiring base 1 that is away from the wall (located in front of the staff), the internal wiring port 302 on the wiring base 1 will be in the back direction relative to the external wiring port 301 (staff). Therefore, when wiring the wiring base 1, the user wire should be installed into the internal wiring port 302 first. At this time, the third threaded hole 203 at the outer end of the internal wiring port 302 will not be able to function. The user wire can only be locked and fixed by passing the locking bolt in the second thread 202 through the first threaded hole 201 and the external wiring port 301 with the help of an L-shaped tightening auxiliary tool. After fixing it, the branch cable can be passed into the external wiring port 301. Since the first threaded hole 201 is facing the staff, it is convenient to fix the branch cable through the first threaded hole 201, thereby completing the wiring fixation function of the wiring base 1 located away from the wall.

[0042] In an optional embodiment, the wiring base 1 includes an upper wiring base 101 and a lower wiring base 102. The upper wiring base 101 and the lower wiring base 102 are detachably connected. The upper wiring base 101 and the lower wiring base 102 are assembled to form an external wiring port 301, and the internal wiring port 302 is opened on the lower wiring base 101.

[0043] Furthermore, semicircular grooves are respectively formed on the opposite surfaces of the upper wiring base 102 and the lower wiring base 101 , and the external wiring port 301 is formed by combining the semicircular grooves of the upper wiring base 102 and the semicircular grooves of the lower wiring base 101 .

[0044] In the above embodiment, the wiring base 1 is divided into two parts, the area of ​​the upper part is smaller than the area of ​​the lower part as a whole, and semicircular grooves are respectively provided on the opposite surfaces of the upper and lower wiring bases. The first threaded hole 201 is penetrated in the upper wiring base 102. When the upper wiring base 102 and the lower wiring base 101 are combined together, the two semicircular grooves will form a circle, that is, the external wiring port 301, and the internal wiring port 302 is arranged below the semicircular groove on the end face of the lower wiring base 101 at intervals. By dividing the wiring base 1 into two parts, the upper wiring base 102 and the lower wiring base 101 can be spliced ​​together or separated from each other, so that the branch cable can be directly inserted into the semicircular groove of the lower wiring base 101 from the outside, and then the branch cable is enclosed by the semicircular groove of the upper wiring base 102.

[0045] In an optional embodiment, a snap-fit ​​assembly 4 is provided on the opposing surfaces of the upper wiring base 102 and the lower wiring base 101, and the upper wiring base 102 and the lower wiring base 101 are detachably connected through the snap-fit ​​assembly 4. The snap-fit ​​assembly 4 includes a guide lock groove 402 and a locking bar 401 that cooperates with the guide lock groove 402. The guide lock groove 402 is opened on the bottom end surface of the upper wiring base 102 along the thickness direction of the wiring base 1, and the locking bar 401 is protruded on the top end surface of the lower wiring base 101 corresponding to the guide lock groove 402.

[0046] In the above embodiment, the upper wiring base 102 is provided with a straight guide lock groove 402 on both sides of the semicircular groove along the direction of the thickness of the wiring base 1, and the length of the guide lock groove 402 is the same as the thickness of the wiring base 1, that is, the guide lock groove 402 runs through the bottom end of the upper wiring base 102 from front to back. Correspondingly, the lower wiring base 101 is provided with a straight lock strip 401 on both sides of the semicircular groove along the direction of the thickness of the wiring base 1, and the length of the lock strip 401 can be the same as the thickness of the wiring base 1. The thickness of the wire base 1 is consistent and can also be smaller than the thickness of the wiring base 1. Through the action of the guide lock groove 402 and the lock bar 401, when the branch cable is clamped into the groove on the lower wiring base 101, the upper wiring base 102 can be easily assembled and fixed together from top to bottom or from bottom to top. For workers operating in a small space, it is convenient for workers to install the branch cable in the external wiring port 301, thereby improving installation efficiency. There is no need to add other operating procedures, and the upper wiring base 102 can be slid and fixed thereon.

[0047] In an optional embodiment, since the upper wiring base 102 is in a vertical state when in use, in order to prevent the upper wiring base 102 from sliding downward and disengaging when the upper wiring base 102 is clamped on the lower wiring base 101, a limit plate can be provided on the outer side of one end of the guide lock groove 402. When the upper wiring base 102 is clamped on the lower wiring base 101, the end where the limit plate is provided is defaulted to the upper end of the upper wiring base 102, and the guide lock groove 402 at the open end is clamped from top to bottom on the locking bar 401. When it slides to the bottom (the two semicircular grooves are aligned and spliced ​​to form a circle), the upper wiring base 102 will be limited and fixed under the action of the limit plate, and cannot continue to slide downward, thereby playing a certain fixing role.

[0048] In an optional embodiment, the diameter of the guide lock groove 402 is gradually reduced from the bottom wall toward the groove opening, the length of the locking bar 401 is the same as the length of the guide lock groove 402, and the outer diameter of the locking bar 401 is gradually reduced from the outside toward the end face of the wiring base 1.

[0049] When the guide locking groove 402 and the locking bar 401 are arranged in this structure, the upper wiring base 102 is not easily pulled out directly under the action of external force. When the guide locking groove 402 is pulled by the external force, the angles on both sides of the top of the guide locking groove 402 will be tightly stuck and not easy to come off. Then, after the locking bolt is passed through the first threaded hole 201, the locking bolt will tightly abut against the outer wall of the branch cable, thereby firmly fixing the upper wiring base 102 and not easily sliding downward and falling off relative to the lower wiring base 101. Alternatively, a locking bolt with a nut can be used. When the bolt is passed inside and tightly abuts against the outer wall of the cable, the nut also presses the upper wiring base 102 tightly in the direction of the lower wiring base 101, so that the guide locking groove 402 and the locking bar 401 are tightly fitted together and not easy to slide downward relative to each other.

[0050] In an optional embodiment, the wiring base 1 is arranged in a fan shape, and the bottom end of the wiring base 1 is a planar structure. There are five wiring bases 1, and the five wiring bases 1 form equidistant angles between each other.

[0051] In the above embodiment, the five wiring bases 1 are assembled together through the insulating connector 5 with the mounting opening 502. During assembly, the wiring base 1 can be directly clamped into the five mounting openings 502 of the insulating connector 5. When the five wiring bases 1 are installed on the insulating connector 5, a hollow disc-shaped structure will be formed. At the center of the insulating connector 5, there is a pentahedron-like hollow structure. After the wiring base 1 is installed, the side surface with the third threaded hole 203 will form the five sides of the hollow structure. That is, the five wiring bases 1 are jointly enclosed by the side surfaces with the third threaded hole 203 through the action of the insulating connector 5 to form a pentahedron-like cavity. Through the action of the cavity, the L-shaped tightening auxiliary tool can be passed from there through the third threaded hole 203 and the internal wiring port 302 to the second threaded hole 202, and the bolt inside it can be moved toward the external wiring port 301, so that the branch cable inside it is abutted and fixed.

[0052] In an optional embodiment, a locking bolt is disposed in the second threaded hole 202, and the length of the locking bolt is less than the length of the second threaded hole 202. Auxiliary grooves are provided at both ends of the locking bolt, which are suitable for cooperating with auxiliary tools to move the locking bolt into the external wiring port 301 or the internal wiring port 302 to abut against the outer wall of the cable, so as to fasten the cable to the wiring port.

[0053] In the above embodiment, the locking bolt is directly installed in the second threaded hole 202 when each wiring base 1 is manufactured. The length of the locking bolt is less than the length of the second threaded hole 202, leaving space for the locking bolt to move. In the subsequent use, the locking bolt in the second threaded hole 202 is directly moved toward the internal wiring port 302 or the external wiring port 301 by using an auxiliary tool by directly utilizing the function of the first threaded hole 201 or the third threaded hole 203. In this way, the locking bolt in the second threaded hole 202 can be flexibly moved forward or backward for wiring bases 1 at different positions.

[0054] 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 who makes various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention still fall within the scope of protection of the present invention.
