Description

Technical Field

[0001] This utility model relates to the field of plug technology, specifically to a high-current one-to-many busbar bracket. Background Technology

[0002] High-current power cord plugs contain multiple live wires, neutral wires, and one ground wire. (See attached image.) Figure 1 Due to the limitation on the number of core wires 11 in the main line 1, it is necessary to connect the core wires 11 in the main line 1 to multiple auxiliary wires 2 so that the main line 1 can be connected to a sufficient number of terminals to meet electrical requirements. For example, when a five-core main line needs to be connected to seven terminals to achieve a combination of three sets of live wires, neutral wires and one ground wire, it is necessary to connect one of the core wires 11 to the connection terminals of three auxiliary wires 2.

[0003] The existing overlapping methods are as follows: Figure 1 As shown, strip the insulation from the end of core wire 11 to expose approximately 2mm of the inner core. Then, strip the insulation from the ends of the three auxiliary wires 2 and overlap them with the exposed portion of core wire 11, and then perform the wiring process. Alternatively, as shown... Figure 2 As shown, all the core wires of the main line 1 are connected to the corresponding terminals. Then, a first exposed core portion is formed on one of the core wires 11, and a second exposed core portion is formed on the auxiliary line 2. The second exposed core portion is overlapped with the first exposed core portion and wired. Then, both ends of the auxiliary line 2 are connected to the corresponding terminals.

[0004] The drawback of the existing splicing method is that the outer diameter of the connection part includes multiple conductive wires. Since high-current cables are generally thicker, the outer diameter of the connection part is too large. In subsequent processes, when the glue part of the plug is injection molded, wire bursting is likely to occur (the conductive wire bursts out of the side of the glue and cannot be wrapped), resulting in product defects. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a high-current one-to-many busbar bracket to reduce the outer diameter of the wiring part and avoid the problem of wire bursting during the injection molding of the plug product.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-current one-to-many busbar bracket includes a conductive bracket, a branching adhesive base, and a plurality of terminals;

[0008] The conductive support includes a support body, which has an inlet on one side and three outlets on the other side.

[0009] Three of the multiple terminals are respectively connected to the three output ends of the conductive bracket;

[0010] The wire splitting adhesive platform is encased in the bracket body by injection molding. The wire splitting adhesive platform is provided with a plurality of partitions, which form a plurality of cable routing grooves on the wire splitting adhesive platform. Each cable routing groove corresponds to a terminal.

[0011] The inlet includes a U-shaped groove and a connecting part. The U-shaped groove is connected to the bracket body through the connecting part. The opening direction of the U-shaped groove is the same as the opening direction of the wiring groove.

[0012] The first end of the connecting part is connected to the U-shaped groove, and the second end is connected to the bracket body. The shape of the bottom of the U-shaped groove is adapted to the first end, and the thickness of the first end is less than the thickness of the second end, and a step is formed on the upper surface of the connecting part; the upper and lower surfaces of the second end are flush with the bracket body.

[0013] The output end is a connecting piece, which is connected to the top of the bracket body and perpendicular to the bracket body.

[0014] The connecting piece is provided with a connecting hole, and correspondingly, one end of the terminal that mates with the connecting piece is provided with a connecting post, and the connecting post is adapted to the connecting hole.

[0015] The bracket body has a through hole at the corresponding outlet position, and the branching adhesive platform does not cover the through hole.

[0016] The inlet, the outlet, and the corresponding cable tray are on the same horizontal line; the maximum thickness of the inlet is 2-40mm.

[0017] The second end of the partition is provided with an extension portion, which extends beyond the dividing plate. The thickness of the extension portion is less than the thickness of the partition, and steps are formed at the connection between the extension portion and both sides of the partition. The second end is the end away from the inlet end.

[0018] The cable tray corresponding to the outlet end is the first cable tray. The first ends of the partitions on both sides of at least one first cable tray are inclined into the first cable tray to form a figure-eight structure. The cable distribution table is provided with seven cable trays, including three first cable trays, and the three first cable trays are located at the second, fifth and seventh positions from left to right.

[0019] The output end is located on the side of the splitter plate, and the first end of the wiring groove corresponding to the output end is recessed in the direction toward the second end to form a step.

[0020] By adopting the above solution, this utility model uses a conductive bracket to lead out multiple terminals, allowing the conductive bracket to directly connect to the terminals instead of the existing auxiliary wires. Then, by injection molding a wire distribution plate onto the conductive bracket and forming a wiring groove, insulation separation between the multiple terminals is ensured. In use, simply strip the insulation of the core wire in the main wire that needs to connect to multiple terminals to expose the core, and then connect this exposed core to the input end of the conductive bracket to complete the connection between the core wire and multiple terminals. For the other core wires of the main wire, they can be directly connected to the terminals through their respective wiring grooves. It is evident that the structure of this utility model effectively reduces the outer diameter of the wiring section, avoiding the problem of wire bursting during injection molding of the plug product, and also effectively isolates the various connecting terminals.

It 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 component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0036] In the description of this application, "plural" means two or more, unless otherwise explicitly specified. "First end" refers to the direction towards the inlet, and "second end" refers to the direction towards the outlet and is opposite to the first end. "Above" refers to the direction in which the opening of the wiring trough 42 faces, and "below" refers to the direction opposite to "above".

[0037] As shown in 3 and 4, this utility model discloses a high-current one-to-many busbar bracket, which includes a conductive bracket 30, a branching adhesive platform 40 and a plurality of terminals 50.

[0038] The conductive support 30 includes a support body 31, which has an inlet on one side and three outlets on the other side.

[0039] Three of the plurality of terminals 50 are respectively connected to the three output ends of the conductive bracket 30;

[0040] The wire splitting plate 40 is encased in the bracket body 31 by injection molding. The wire splitting plate 40 is provided with a plurality of partitions 41, which form a plurality of cable routing grooves 42 on the wire splitting plate 40. The cable routing grooves 42 correspond one-to-one with the terminals 50. The plurality of terminals 50 are located at the second end of the cable routing grooves 42.

[0041] This invention uses a conductive bracket 30 to lead out multiple terminals, allowing the conductive bracket 30 to directly connect to the terminals 50 instead of existing auxiliary wires. Then, by injection molding a wire distribution plate 40 onto the conductive bracket 30 and forming a wiring groove 42, insulation separation is ensured between the multiple terminals 50. In use, simply strip the insulation of the core wire in the main wire that needs to connect to multiple terminals 50 to expose the core, and then connect this exposed core to the input end of the conductive bracket 30. This completes the connection between the core wire and the multiple terminals 50. Other core wires in the main wire are directly connected to the terminals 50 through their respective wiring grooves 42. Therefore, the structure of this invention effectively reduces the outer diameter of the wiring section, avoiding the problem of wire bursting during injection molding of the plug product, and also effectively isolates the various connecting terminals 50.

[0042] like Figure 4-6 As shown, in this embodiment, the maximum thickness d of the inlet end is 2-40mm, which includes a U-shaped groove 32 and a connecting part 33. The U-shaped groove 32 is connected to the bracket body 31 through the connecting part 33, and the opening direction of the U-shaped groove 32 is the same as the opening direction of the wiring groove 42. Specifically, the first end of the connecting part 33 is connected to the U-shaped groove 32, and the second end is connected to the bracket body 31. The shape of the bottom of the first end is adapted to the groove of the U-shaped groove 32, and the thickness of the first end is less than the thickness of the second end, and a step is formed on the upper surface of the connecting part 33; the upper and lower surfaces of the second end are flush with the bracket body 31. The U-shaped groove 32 provides support for the main line and also provides a wiring position for the core wires that need to be connected to multiple terminals 50. The main line is placed in the U-shaped groove 32, and then the core wires that need to be connected to multiple terminals 50 are sorted out and stripped to form exposed core sections. The exposed core sections are then wired to the U-shaped groove 32 or the connecting part 33.

[0043] The output end is a connecting piece 34, which is connected to the upper part of the bracket body 31 and perpendicular to the bracket body 31. The connecting piece 34 is provided with a connecting hole, and correspondingly, the terminal 50 has a connecting post 51 at one end that mates with the connecting piece 34, and the connecting post 51 is adapted to the connecting hole. Wiring is also required between the connecting piece 34 and the terminal 50, and the connecting hole and the connecting post 51 make the wiring between the terminal 50 and the connecting piece 34 more convenient.

[0044] The bracket body 31 has a through hole 311 at the corresponding outlet position, and the cable distribution plate 40 does not cover the through hole 311. The inlet, the outlet, and the cable tray 42 corresponding to the outlet are on the same horizontal line. Therefore, the core wires that need to be connected to multiple terminals 50 in the main line can also be wired through the through hole 311 in the conductive bracket 30.

[0045] In this embodiment, the main line and the U-shaped groove 32 can be connected by riveting, and the connecting piece 34 and the terminal 50 can be connected by fusion welding, solder welding, or by riveting structure.

[0046] like Figure 7-8 As shown, the second end of the partition 41 of the splitting glue station 40 is provided with an extension 411. The extension 411 extends out of the splitting glue station 40. The thickness of the extension 411 is less than the thickness of the partition 41. Steps are formed at the connection between the partition 41 and the extension 411 on both sides. The second end is the end away from the inlet end.

[0047] The cable tray 42 corresponding to the outlet end is the first cable tray 421. The first ends of the partitions 41 on both sides of at least one first cable tray 421 are inclined inward to the first cable tray 421 to form a figure-eight structure. In this embodiment, the cable distribution plate 40 is provided with seven cable trays 42, including three first cable trays 421, and the three first cable trays 421 are located at the second, fifth and seventh positions from left to right, respectively.

[0048] One end is located on the side of the splitter plate 40, and the first end of the cable tray 42 corresponding to the end is recessed towards the second end to form a step.

[0049] In summary, this invention uses a conductive bracket 30 to lead out multiple terminals, allowing the conductive bracket 30 to directly connect to the terminals 50 instead of existing auxiliary wires. Then, by injection molding a wire distribution platen 40 onto the conductive bracket 30 and forming a wiring groove 42, insulation separation between the multiple terminals 50 is ensured. This invention can effectively reduce the outer diameter of the wiring section, avoid the problem of wire bursting during the injection molding of the plug product, and effectively isolate the various connecting terminals 50.

[0050] The above description is merely an embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
