Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and its feature is a socket-type busbar. Background Technology

[0002] With the rapid development of cities and the increasing number of high-rise buildings, the electrical load on buildings has increased dramatically. Traditional electrical wires and cables, due to their small capacity, inconvenient branching, and difficulty in bundled management, are gradually being replaced by busbars, which offer larger capacity, easier branching, and more convenient bundled management. In existing technology, busbars typically consist of conductive bars, insulated supports, and a protective outer shell. These busbars can carry large currents and offer high safety and reliability. However, existing busbars are difficult to use for connecting multiple external electrical components. In power distribution systems, when the main transmission line needs to connect to multiple branch transmission lines, they are usually directly connected in the electrical box or cabinet via the main transmission line. This connection method is inconvenient to install and remove, and the main and branch transmission lines are exposed, resulting in insufficient safety. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a socket-type busbar trunking that can accommodate multiple external electrical components and has high safety, in order to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a socket-type busbar trunking, including an insulating shell, a conductive busbar, and an outer insulator. The insulating shell has a conductive busbar groove extending in the left-right direction. The conductive busbar is inserted into the conductive busbar groove, and the left and right ends of the conductive busbar extend outward from the insulating shell. The front part of the insulating shell has a front socket for inserting external power connection components, and the front part of the conductive busbar protrudes into the front socket. The rear part of the insulating shell has a rear socket for inserting external power connection components, and the rear part of the conductive busbar protrudes into the rear socket. The outer insulator covers the upper, lower, left, and right ends of the insulating shell. The left end of the outer insulator also covers the left end of the conductive busbar and closes the left end of the conductive busbar. The right end of the outer insulator also covers the right end of the conductive busbar, and the right end of the conductive busbar extends outward from the right end of the outer insulator. The right end of the conductive busbar is used to connect to the external power connection components.

[0005] In the above technical solution, the insulating shell includes a front insulating shell and a rear insulating shell, which are back-to-back abutting each other. The conductive busbar groove includes a front groove portion 41 and a rear groove portion 42. The front groove portion 41 is located at the rear of the front insulating shell, and the rear groove portion 42 is located at the front of the rear insulating shell. The front portion of the conductive busbar is inserted into the front groove portion 41, and the rear portion of the conductive busbar is inserted into the rear groove portion 42. The front and rear insulating shells are symmetrical, with the front insertion port located at the front of the front insulating shell and the rear insertion port located at the rear of the rear insulating shell.

[0006] In the above technical solution, the conductive bus includes a live wire conductive bus, a ground wire conductive bus, and a neutral wire conductive bus, which are arranged at intervals from top to bottom.

[0007] In the above technical solution, the front and rear connectors are arranged in three rows from top to bottom. The live wire conductor is exposed in the top row of front and rear connectors, the ground wire conductor is exposed in the middle row of front and rear connectors, and the neutral wire conductor is exposed in the bottom row of front and rear connectors. The front connectors have multiple rows, with a front vertical partition between adjacent rows, and the front vertical partition is integrally connected to the insulating shell. The rear connectors have multiple rows, with a rear vertical partition between adjacent rows, and the rear vertical partition is integrally connected to the insulating shell. The front part of the conductor passes laterally through the middle of the front connector, and a front horizontal partition is provided on the front side of the conductor, integrally connected to the front vertical partition. The rear part of the conductor passes laterally through the middle of the rear connector, and a rear horizontal partition is provided on the rear side of the conductor, integrally connected to the rear vertical partition.

[0008] In the above technical solution, the right end of the live wire conductor is provided with a live wire connection lug, the right end of the ground wire conductor is provided with a ground wire connection terminal, and the right end of the neutral wire conductor is provided with a neutral wire connection lug.

[0009] In the above technical solution, the right end of the live wire busbar is connected to two vertically parallel live wire connection terminals, the right end of the ground wire busbar is connected to two vertically parallel ground wire connection terminals, and the right end of the neutral wire busbar is connected to two vertically parallel neutral wire connection terminals. The live wire connection terminals, ground wire connection terminals, and neutral wire connection terminals are arranged sequentially from front to back.

[0010] In the above technical solution, the upper end, lower end, left end and right end of the outer insulator are integrally formed and connected.

[0011] The beneficial effects of this utility model are: (1) Since the front part of the insulating shell is provided with a front socket for inserting external electrical components, the front part of the conductive busbar is exposed inside the front socket, and the rear part of the insulating shell is provided with a rear socket for inserting external electrical components, the rear part of the conductive busbar is exposed inside the rear socket. Therefore, when the external electrical components are inserted into the front or rear socket, they can achieve electrical connection with the conductive busbar, thereby enabling this utility model to connect multiple external electrical components, such as connecting to the distribution busbar trunk, and the connection process is very convenient; (2) Since the conductive busbar is inserted into the conductive busbar groove of the insulating shell, the upper end, lower end, left end and right end of the insulating shell are covered with an outer insulator, and the left end of the outer insulator is also covered with an outer insulator. The outer insulator covers the left end of the conductor and seals the left end of the conductor. The right end of the outer insulator also covers the right end of the conductor. Therefore, on the one hand, the insulating shell can fix the conductor, and the outer insulator can further cover and fix the insulating shell and the conductor at the same time, so that the socket-type busbar trunking forms a stable whole. On the other hand, the insulating shell and the outer insulator can work together as the insulator of the socket-type busbar trunking, forming a good insulation effect on the conductor, avoiding the conductor from being directly exposed to the outside, and ensuring high safety. (3) Since the right end of the conductor extends outward from the right end of the outer insulator, the present invention can use the right end of the conductor to connect external power connection components, such as connecting the main power transmission busbar trunking.

[0018] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings. Example 1

[0019] like Figures 1-5As shown, this embodiment is a socket-type busbar trunking, including an insulating housing 1, a conductive busbar 2, and an outer insulator 3. The insulating housing 1 has a conductive busbar groove 4 extending in the left-right direction. The conductive busbar 2 is inserted into the conductive busbar groove 4, and the left and right ends of the conductive busbar 2 extend outward from the insulating housing 1 respectively. The front part of the insulating housing 1 has a front socket 5 for inserting an external power connection component (not shown in the figure), and the front part of the conductive busbar 2 protrudes into the front socket 5. The rear part of the insulating housing 1 has a power connection component (not shown in the figure) for inserting an external power connection component. (Not shown) The rear insertion port 6 is inserted, and the rear part of the conductive busbar 2 protrudes into the rear insertion port 6; the outer insulator 3 covers the upper end, lower end, left end and right end of the insulating shell 1, the left end of the outer insulator 3 also covers the left end of the conductive busbar 2 and closes the left end of the conductive busbar 2, the right end of the outer insulator 3 also covers the right end of the conductive busbar 2, and the right end of the conductive busbar 2 extends outward from the right end of the outer insulator 3, and the right end of the conductive busbar 2 is used to connect to an external power connection component (not shown).

[0020] This invention features a front socket 5 at the front of the insulating housing 1 for inserting external electrical components, with the front of the conductive busbar 2 protruding into the front socket 5. The rear of the insulating housing 1 also has a rear socket 6 for inserting external electrical components, with the rear of the conductive busbar 2 protruding into the rear socket 6. Therefore, when an external electrical component is inserted into either the front socket 5 or the rear socket 6, it can achieve electrical connection with the conductive busbar 2. This allows the invention to connect multiple external electrical components, such as those used for connecting to power transmission busbar trunking, making the connection process very convenient. Furthermore, the conductive busbar 2 is inserted into the conductive busbar groove 4 of the insulating housing 1. The upper, lower, left, and right ends of the insulating housing 1 are covered by an outer insulator 3, with the left end of the outer insulator 3 also covering the conductive busbar 2. The left end of the conductive busbar 2 is enclosed outside the left end, and the right end of the outer insulator 3 is simultaneously covered outside the right end of the conductive busbar 2. Therefore, on the one hand, the insulating shell 1 can fix the conductive busbar 2, and the outer insulator 3 can further cover and fix the insulating shell 1 and the conductive busbar 2 at the same time, so that the socket-type busbar trunking forms a stable whole. On the other hand, the insulating shell 1 and the outer insulator 3 can together serve as the insulator of the socket-type busbar trunking, forming a good insulation effect on the conductive busbar 2, preventing the conductive busbar 2 from being directly exposed to the outside, and ensuring high safety. Since the right end of the conductive busbar 2 extends outward from the right end of the outer insulator 3, this utility model can use the right end of the conductive busbar 2 to connect to external power connection components, such as connecting to the main power transmission busbar trunking.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the insulating housing 1 includes a front insulating housing 11 and a rear insulating housing 12, which are back-to-back. The conductive busbar groove 4 includes a front groove portion 41 and a rear groove portion 42. The front groove portion 41 is located at the rear of the front insulating housing 11, and the rear groove portion 42 is located at the front of the rear insulating housing 12. The front portion of the conductive busbar 2 is inserted into the front groove portion 41, and the rear portion of the conductive busbar 2 is inserted into the rear groove portion 42. This structure allows the conductive busbar 2 to be inserted more easily into the front groove portion 41 and the rear groove portion 42. Preferably, the front insulating housing 11 and the rear insulating housing 12 are symmetrical, with the front insertion port 5 located at the front of the front insulating housing 11 and the rear insertion port 6 located at the rear of the rear insulating housing 12.

[0022] like Figures 1-5 As shown, the conductive busbar 2 includes a live wire conductive busbar 21, a ground wire conductive busbar 22, and a neutral wire conductive busbar 23, which are spaced apart from top to bottom. The front connector 5 and rear connector 6 each have three rows from top to bottom. The live wire conductive busbar 21 protrudes into the top row of front connectors 5 and rear connectors 6, the ground wire conductive busbar 22 protrudes into the middle row of front connectors 5 and rear connectors 6, and the neutral wire conductive busbar 23 protrudes into the bottom row of front connectors 5 and rear connectors 6. The front connectors 5 have multiple rows, with a front vertical partition 13 between adjacent rows of front connectors 5, and the front vertical partition 13 is integrally connected to the insulating shell 1. The rear connectors 6 have multiple rows, with a rear vertical partition between adjacent rows of rear connectors 6, and the rear vertical partition is integrally connected to the insulating shell 1. The front part of the conductive busbar 2 passes laterally through the middle of the front socket 5. A front horizontal partition 14 is provided on the front side of the conductive busbar 2, and the front horizontal partition 14 is integrally connected with the front vertical partition 13. The rear part of the conductive busbar 2 passes laterally through the middle of the rear socket 6. A rear horizontal partition 15 is provided on the rear side of the conductive busbar 2, and the rear horizontal partition 15 is integrally connected with the rear vertical partition.

[0023] As a preferred embodiment of this utility model, such as Figures 1-5 As shown, the live wire busbar 21, the ground wire busbar 22, and the neutral wire busbar 23 are copper or aluminum busbars, respectively. The right end of the live wire busbar 21 is provided with a live wire connection lug 211, the right end of the ground wire busbar 22 is provided with a ground wire connection terminal 221, and the right end of the neutral wire busbar 23 is provided with a neutral wire connection lug 231. Example 2

[0024] like Figure 6As shown, this is a preferred embodiment of the present invention. The structure of Embodiment Two differs from that of Embodiment One in that, in this preferred embodiment, the right end of the live wire busbar 21 is connected to two vertically arranged live wire connection terminals 212, the right end of the ground wire busbar 22 is connected to two vertically arranged ground wire connection terminals 222, and the right end of the neutral wire busbar 23 is connected to two vertically arranged neutral wire connection terminals 232. The live wire connection terminals 212, ground wire connection terminals 222, and neutral wire connection terminals 232 are arranged sequentially from front to back. The structure of Embodiment Two is the same as the other structures of Embodiment One, and will not be described again here.

[0025] In a preferred embodiment of this invention, in Embodiments 1 and 2, the upper, lower, left, and right ends of the outer insulator 3 are integrally formed and connected. The outer insulator 3 is integrally cast from an inorganic composite material, comprising the following components by volume: non-metallic mineral particles: quartz powder (325 powder): 12%; calcium carbonate powder (400 mesh powder): 7.5%; high-purity fine quartz sand (40 mesh particles): 24%; high-purity coarse quartz sand (6-8 mesh particles): 37%; ore raw material flame retardant: Al(OH) 32%-3%; epoxy resin and curing agent 16-18%; the synthetic materials are uniformly stirred and synthesized at approximately 40°C. When manufacturing a socket-type busbar trunking, the conductive busbar 2 is first inserted into the conductive busbar groove 4 of the insulating shell 1. Then, the conductive busbar 2 and the insulating shell 1 are placed together in the mold. Next, inorganic composite material is poured in. After the whole is fixed, the process is completed by preheating in a drying room at 30°C for more than 4 hours to form the outer insulator 3 and make the socket-type busbar trunking form a stable whole.

[0026] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
