Description

Technical Field

[0001] This utility model relates to the field of conductive busbar technology, specifically a low-resistance conductive busbar structure for a cable branch box. Background Technology

[0002] Cable distribution boxes are a key component of power distribution lines, primarily used for cable branching and switching to ensure the reliability and security of power supply. With the increasing cabling of power distribution networks, cable distribution boxes can be used to connect multiple cable branches when small-capacity independent loads are concentrated in one area. Cable distribution boxes are widely used outdoors. With technological advancements, cable distribution boxes with switches are becoming increasingly common. Since urban cables often use dual-circuit power supply, some people directly refer to these switch-equipped distribution boxes as outdoor ring main units (RMMs). However, most of these RMMs currently cannot achieve distribution network automation. Nevertheless, some manufacturers have introduced outdoor RMMs that can achieve distribution network automation, blurring the lines between cable distribution boxes and RMMs.

[0003] To facilitate cable connections, cable distribution boxes are equipped with conductive busbars. Existing conductive busbars have multiple connectors for connecting multiple cables. However, the distance between the connectors on existing conductive busbars is fixed. After some cables are connected to the distribution box, the spacing between them is different. Using connectors with fixed spacing is not conducive to subsequent wiring and causes maintenance inconvenience.

[0004] Therefore, a low-resistance conductive busbar structure for cable branch boxes is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-resistance conductive busbar structure for cable branch boxes, which has advantages such as easy adjustment of wiring positions. It solves the problem that the distance between the terminals on existing conductive busbars is fixed, and the spacing between some cables varies after they are connected to the branch box. Using terminals with fixed spacing is not conducive to subsequent line organization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-resistance conductive busbar structure for a cable branch box, including a housing, an electrical connection component disposed inside the housing, and a positioning component for fixing the electrical connection component disposed inside the housing;

[0007] The power connection assembly includes a copper busbar fixedly installed inside the housing. Multiple terminals are provided on the upper side of the copper busbar. The upper surface of the copper busbar is provided with a toothed groove. A conductive plate is fixedly connected to the lower part of the terminal. The bottom of the conductive plate is provided with a retaining tooth that matches the toothed groove.

[0008] The positioning component includes a positioning plate that abuts against the top of the conductive sheet, an mounting plate is provided on the upper side of the positioning plate, a plurality of springs are fixedly connected between the mounting plate and the positioning plate, and an mounting assembly is provided between the mounting plate and the outer shell.

[0009] Furthermore, a strip-shaped opening is provided on the upper surface of the housing, and the upper end of the connector extends to the outside of the housing through the strip-shaped opening.

[0010] Furthermore, four mounting pieces are fixedly connected to the outer wall of the outer shell, and the four mounting pieces are symmetrically distributed on the wider sides of the outer shell.

[0011] Furthermore, one end of the copper busbar is fixedly connected to a power connector, which extends to the outside of the housing.

[0012] Furthermore, the number of mounting components is two sets, and the two sets of mounting components are symmetrically distributed on the narrower sides of the outer shell. Each mounting component includes a connecting block and a fixing block. The connecting block is fixedly connected to the end of the mounting plate, and the fixing block is fixedly connected to the outer wall of the outer shell.

[0013] Furthermore, an opening is provided on the side wall of the outer casing near the connecting block, and the connecting block extends to the outside of the outer casing through the opening, corresponding to the top of the fixing block.

[0014] Furthermore, a fixing screw is inserted into the inner side of the connecting block, and the fixing screw is threaded into the inside of the fixing block.

[0015] Compared with the prior art, this utility model provides a low-resistance conductive busbar structure for cable branch boxes, which has the following advantages:

[0016] This cable branch box features a low-resistance conductive busbar structure. Through the combined use of the connection component and the positioning component, the distance between adjacent connectors can be easily adjusted, thereby enabling the adjustment of the connection position. This provides convenience for cable connection and subsequent wiring. The overall structure is compact, easy to use, and highly practical. It solves the problem that the distance between connectors on existing conductive busbars is fixed, and some cables have different spacings after being connected to the branch box. Using connectors with fixed spacing is not conducive to subsequent wiring organization. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1 to 6 The low-resistance conductive busbar structure of the cable branch box in this embodiment includes a housing 1, a power connection component is provided inside the housing 1, and a positioning component for fixing the power connection component is also provided inside the housing 1.

[0026] The power connection assembly includes a copper busbar 3 fixedly installed inside the housing 1. Multiple terminals 2 are provided on the upper side of the copper busbar 3. The upper surface of the copper busbar 3 is provided with a toothed groove 5. A conductive piece 6 is fixedly connected to the lower part of the terminal 2. The bottom of the conductive piece 6 is provided with a retaining tooth 7 that matches the toothed groove 5. A power connection head 4 is fixedly connected to one end of the copper busbar 3. The power connection head 4 extends to the outside of the housing 1.

[0027] It should be noted that a strip-shaped opening 15 is provided on the upper surface of the housing 1, and the upper end of the connector 2 extends to the outside of the housing 1 through the strip-shaped opening 15.

[0028] It should be noted that the connector 2, copper busbar 3, conductive plate 6, retaining tooth 7, and connector 4 are all made of copper. Copper has low resistivity and excellent conductivity.

[0029] In this embodiment, the positioning component includes a positioning plate 8 that abuts against the top of the conductive sheet 6. A mounting plate 9 is provided on the upper side of the positioning plate 8. A plurality of springs 10 are fixedly connected between the mounting plate 9 and the positioning plate 8. An installation component is provided between the mounting plate 9 and the outer shell 1. There are two sets of installation components, which are symmetrically distributed on the narrower sides of the outer shell 1.

[0030] The mounting assembly includes a connecting block 11 and a fixing block 12. The connecting block 11 is fixedly connected to the end of the mounting plate 9, and the fixing block 12 is fixedly connected to the outer wall of the housing 1. An opening 14 is provided on the side wall of the housing 1 near the connecting block 11. The connecting block 11 extends to the outside of the housing 1 through the opening 14 and corresponds to the top of the fixing block 12. A fixing screw 13 is inserted into the inner side of the connecting block 11 and is threaded into the inside of the fixing block 12.

[0031] It should be noted that when the fixing screw 13 combines and fixes the connecting block 11 and the fixing block 12, the spring 10 is in a tightened state, thereby causing the positioning plate 8 to be in close contact with the conductive sheet 6, ensuring that the locking teeth 7 and the tooth groove 5 are stably engaged, so that the position of the connector 2 can remain stable. When the fixing screw 13 is removed, the spring 10 can release its elastic force to push the mounting plate 9 to move upward, and drive the connecting block 11 to move upward along the opening 14.

[0032] It should be added that four mounting pieces 16 are fixedly connected to the outer wall of the outer shell 1. The four mounting pieces 16 are symmetrically distributed on the wider sides of the outer shell 1 and are used to fix the outer shell 1 inside the branch box.

[0033] The working principle of the above embodiments is as follows:

[0034] When it is necessary to adjust the distance between adjacent connectors 2, remove the fixing screws 13 at both ends of the mounting plate 9. The spring 10 releases its elastic force to push the mounting plate 9 upward and drive the connecting block 11 to move upward along the opening 14. Then, pull the connector 2 upward, causing the conductive plate 6 to press upward against the positioning plate 8 and the spring 10, so that the retaining tooth 7 separates from the tooth groove 5. After separation, the connector 2 can be slid along the strip opening 15 to adjust the distance between adjacent connectors 2 and adjust the wiring position. After adjusting to the appropriate position, release the connector 2 so that the retaining tooth 7 re-engages with the tooth groove 5. The spring 10 will also release its elastic force to reset the positioning plate 8 downward. Then, press down the connecting block 11 to drive the mounting plate 9 to press down against the spring 10 and install the fixing screws 13 to complete the fixing.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. It should be noted that the orientation or positional relationship indicated herein is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
