Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical engineering technology, specifically to a standardized side-expansion bus connector. Background Technology
[0002] Side expansion bus connectors are devices used for side expansion connections of ring main units (gas-insulated cabinets, solid-state cabinets). They enable flexible cabinet combinations through multi-branch series connection and are suitable for the expansion needs of modular ring main units.
[0003] The existing standardized side expansion bus connectors lack a fixing structure for the braided copper strip during assembly, which can easily cause it to fall into the gap between the two ring main units. This requires separating the two ring main units again, which is extremely cumbersome and does not improve installation efficiency. In addition, the plugs of the side expansion bus connectors are exposed to the external environment, and their surfaces may be contaminated with oil, dust and other pollutants. They need to be cleaned before plugging in, which increases the time required and does not improve the ease of use. Utility Model Content
[0004] This utility model provides a standardized side-expansion bus connector, which has the advantages of easy fixing and protection, in order to solve the problems of existing connectors that are not conducive to improving installation efficiency and ease of use.
[0005] To achieve the purpose of fixation and protection, this utility model provides the following technical solution: a standardized side-expanding bus connector, including a connector body and a braided copper strip, wherein the middle part of the surface of the connector body is coated with a semiconductor shielding coating layer, and further includes:
[0006] Protective components are disposed on both sides of the connector body surface, the protective components comprising a micro-adhesive acrylate coating and a fluororubber film;
[0007] An auxiliary component disposed on the surface of a braided copper strip, the auxiliary component comprising an auxiliary block and a neodymium magnet.
[0008] As a preferred embodiment of this utility model, an annular tension spring is sleeved on the middle part of the surface of the connector body, and both ends of the annular tension spring are fixedly connected with mounting buckles.
[0009] As a preferred embodiment of this utility model, the mounting buckle has a connecting end inside, and one end of the connecting end is fixedly connected to one end of the braided copper strip.
[0010] As a preferred embodiment of this utility model, the other end of the braided copper strip is fixedly connected to an annular terminal, and the annular terminal is made of copper.
[0011] As a preferred embodiment of this invention, the protective component includes a micro-adhesive acrylate coating adhesively bonded to both sides of the connector body surface, and a fluororubber film is fixedly bonded to the surface of the micro-adhesive acrylate coating.
[0012] As a preferred embodiment of this invention, a tear-off tab is fixedly connected to the outer side of the fluororubber film, and the tear-off tab is used to quickly tear off the protective component.
[0013] As a preferred technical solution of this utility model, the auxiliary component includes an auxiliary block snapped onto the surface of the braided copper strip, and neodymium magnets are fixedly connected to both sides of the bottom surface of the auxiliary block. The neodymium magnets are used to attract the ring main unit and fix the braided copper strip.
[0014] As a preferred embodiment of this utility model, a handle is fixedly connected to the top surface of the auxiliary block, and the handle is made of insulating rubber.
[0015] Compared with the prior art, this utility model provides a standardized side expansion bus connector, which has the following advantages:
[0016] This standardized side-expansion bus connector, by incorporating protective components, reduces surface contaminants such as oil and dust, minimizing the need for wiping. During use, workers can remove the fluororubber film using a peeler, keeping the connection points of the standardized side-expansion bus connector clean. This avoids the need for cleaning the connector's plugs, which are exposed to the external environment and may accumulate oil, dust, and other contaminants before insertion, thus increasing the time required and improving ease of use.
[0017] This standardized side-expansion bus connector uses an auxiliary component to secure the braided copper strip. During use, the braided copper strip is placed at the bottom of the auxiliary block, where the neodymium magnet attracts it to the surface of the ring main unit. The ring main unit is then pushed to allow the conductive copper components inside the standardized side-expansion bus connector to connect with the bus joint of another ring main unit. This maintains the stability of the braided copper strip during installation. After use, the auxiliary component can be removed. This avoids the problem of the braided copper strip easily falling into the gap between two ring main units during assembly due to a lack of securing structure, requiring disassembly and increasing installation time. This improves installation efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-4 This utility model discloses a standardized side-expansion bus connector, including a connector body 1 and a braided copper strip 2. The connector body 1 has a semiconductor shielding coating layer 10 coated on the center of its surface, and also includes:
[0025] The protective components 3 are disposed on both sides of the surface of the connector body 1. The protective components 3 include a micro-adhesive acrylic coating 301 and a fluororubber film 302.
[0026] An auxiliary component 4 is disposed on the surface of the braided copper strip 2. The auxiliary component 4 includes an auxiliary block 401 and a neodymium magnet 402.
[0027] Specifically, an annular tension spring 5 is sleeved in the middle of the surface of the connector body 1, and both ends of the annular tension spring 5 are fixedly connected with mounting buckles.
[0028] In this embodiment, the ring tension spring 5 is used to ensure the stability and reliability of current transmission.
[0029] Specifically, the internal part of the mounting buckle is fitted with a connecting end 6, one end of which is fixedly connected to one end of the braided copper strip 2.
[0030] In this implementation scheme, the connection terminal 6 serves as the connection point.
[0031] Specifically, the other end of the braided copper strip 2 is fixedly connected to a ring-shaped terminal 7, which is made of copper.
[0032] In this implementation scheme, the ring-shaped terminal 7 serves to connect the circuit.
[0033] Specifically, the protective component 3 includes a micro-adhesive acrylic coating 301 that is adhesively connected to both sides of the surface of the connector body 1, and a fluororubber film 302 is fixedly connected to the surface of the micro-adhesive acrylic coating 301; a tear strip 8 is fixedly connected to the outside of the fluororubber film 302, and the tear strip 8 is used to quickly tear off the protective component 3.
[0034] In this embodiment, during use, the operator removes the fluororubber film 302 using the tear strip 8, thereby keeping the connection parts of the standardized side expansion bus connector clean.
[0035] Specifically, the auxiliary component 4 includes an auxiliary block 401 that is snapped onto the surface of the braided copper strip 2. Neodymium magnets 402 are fixedly connected to both sides of the bottom surface of the auxiliary block 401. The neodymium magnets 402 are used to attract the ring main unit and fix the braided copper strip 2.
[0036] In this embodiment, during use, the braided copper strip 2 is placed to the bottom of the auxiliary block 401, and then the neodymium magnet 402, which is magnetic, is attracted to the surface of the ring main unit. Then, the ring main unit is pushed so that the conductive copper parts inside the standardized side expansion bus connector are plugged into the bus connection part of another ring main unit, thus maintaining the stability of the braided copper strip 2 during installation.
[0037] Specifically, a handle 9 is fixedly connected to the top surface of the auxiliary block 401, and the handle 9 is made of insulating rubber.
[0038] In this implementation plan, after installation, simply pull handle 9 to remove auxiliary component 4.
[0039] The working principle and usage process of this utility model are as follows: During use, the operator removes the fluororubber film 302 by tearing off the tearing tab 8, thereby keeping the connection part of the standardized side expansion bus connector clean. The braided copper strip 2 is placed to the bottom of the auxiliary block 401. Then, the neodymium magnet 402 is magnetic and adsorbs onto the surface of the ring main unit. Then, the ring main unit is pushed so that the conductive copper parts inside the standardized side expansion bus connector are inserted into the bus connection part of another ring main unit. After installation, the auxiliary component 4 can be removed by pulling the handle 9.
[0040] In summary, this standardized side-expansion bus connector, by incorporating protective component 3, can reduce surface contaminants such as oil and dust, thus minimizing wiping procedures. During use, operators can remove the fluororubber film 302 using the tear-off tab 8, keeping the connection points of the standardized side-expansion bus connector clean. This avoids the need for cleaning the connector's plugs, which are exposed to the external environment and may have surface contaminants such as oil and dust, requiring additional time before plugging in, thereby improving its ease of use.
[0041] By setting auxiliary component 4, the braided copper strip 2 can be fixed. During use, the braided copper strip 2 is placed at the bottom of auxiliary block 401. Then, the neodymium magnet 402 is magnetic and adsorbs onto the surface of the ring main unit. Then, the ring main unit is pushed so that the conductive copper parts inside the standardized side expansion bus connector are inserted into the bus connection part of another ring main unit. This maintains the stability of the braided copper strip 2 during installation. After use, the auxiliary component 4 can be removed. This avoids the braided copper strip 2 from easily falling into the gap between the two ring main units during assembly due to the lack of a fixing structure, which would require disassembling it again and increasing installation time. This helps to improve installation efficiency.
