Description

Technical Field

[0001] This invention relates to the field of busbar connector technology, and in particular to a novel detachable busbar connector. Background Technology

[0002] Busbar connectors are electrical connection devices used to establish connections between connectors and busbars in power systems. They are used to branch, extend, or transfer power transmission, ensuring low-resistance transmission of high current between different power systems. Traditional busbar connector designs often employ a single row of contacts, with the contacts and housing fixed in a single, non-removable structure. These connectors have limited space, fewer contacts, and restricted current carrying capacity. Furthermore, once assembled, if a malfunction occurs later or internal contacts need to be replaced due to changes in equipment current requirements, the entire connector must be replaced. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a new type of detachable bus connector. By adopting a double-layer lamination design and a reusable disassembly and assembly structure, users can achieve high current carrying capacity in limited space and conveniently replace and install internal components without damaging parts, which is beneficial to improving the efficiency of on-site assembly and subsequent maintenance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a novel detachable busbar connector, comprising a housing, a spring assembly, and a locking buckle. The housing has spring guide grooves on both side walls, and the spring assembly is installed in the spring guide grooves. The spring assembly is detachably connected to the housing via the spring guide grooves. The housing also has a buckle mounting groove in the middle, and loading / unloading holes on both sides. The locking buckle has inverted buckles on both sides and two evenly spaced positioning rods in the middle. The locking buckle is installed in the buckle mounting groove, and the inverted buckles are located in the loading / unloading holes.

[0005] Furthermore, the spring assembly adopts a double-layer stacked structure, including an outer spring and an inner spring. The upper part of the outer spring is provided with two first rectangular positioning holes and a first circular positioning hole. One side of the outer spring is a first positioning surface, and a first circular positioning boss is provided on the first positioning surface. The lower part of the outer spring is provided with evenly spaced first spring teeth, and the top of the first spring teeth is provided with a first spring contact point. The upper part of the inner spring is provided with two second rectangular positioning holes and a second circular positioning hole. One side of the inner spring is a second positioning surface, and a second circular positioning boss is provided on the second positioning surface. The lower part of the inner spring is provided with evenly spaced second spring teeth, and the top of the second spring teeth is provided with a second spring contact point. The first positioning surface of the outer spring and the second positioning surface of the inner spring are fitted together and assembled. After the fitting assembly, the first circular positioning hole and the second circular positioning boss cooperate, the second circular positioning hole and the first circular positioning boss cooperate, and the first rectangular positioning hole and the second rectangular positioning hole coincide.

[0006] Furthermore, the top ends of the two positioning rods are also provided with load-bearing rods, and the housing is also provided with a fixing beam. The fixing beam is located above the buckle mounting groove, and the middle of the housing is also provided with a through hole. When the locking buckle is installed in the buckle mounting groove of the housing, the buckles on both sides of the locking buckle are fixed to the side walls of the loading and unloading holes on both sides of the housing. The two positioning rods of the locking buckle pass through the through hole, the upper surface of the positioning rod abuts against the lower surface of the fixing beam, and the load-bearing rod passes through the first rectangular positioning hole and the second rectangular positioning hole, and matches with the first rectangular positioning hole and the second rectangular positioning hole to realize the axial fixation of the spring assembly.

[0007] Furthermore, the outer spring sheet has a first positioning step on both sides, and the inner spring sheet has a second positioning step on both sides. The first positioning step and the second positioning step abut against the bottom plane of the spring sheet guide groove, thereby fixing the spring sheet assembly in the lateral and longitudinal downward directions.

[0008] The present invention has the following beneficial effects: This invention, through the use of a double-layer stacked spring assembly and a reusable disassembly and assembly structure, enables users to achieve high current carrying capacity in limited space and convenient replacement and installation of internal components without damaging parts, which is beneficial to improving the efficiency of on-site assembly and subsequent maintenance.

Detailed Implementation

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0011] Reference Figure 1-8The present invention provides an embodiment of a novel detachable busbar connector, comprising a housing 10, a spring assembly 20, and a locking buckle 30. The housing 10 has spring guide grooves 12 on both side walls, and the spring assembly 20 is installed in the spring guide grooves 12. The spring assembly 20 is detachably connected to the housing 10 through the spring guide grooves 12. The housing 10 also has a buckle mounting groove 11 in the middle, and loading / unloading holes 14 on both sides. The locking buckle 30 has inverted buckles 31 on both sides and two positioning rods 32 evenly arranged in the middle. The locking buckle 30 is installed in the buckle mounting groove 11, and the inverted buckles 31 are located in the loading / unloading holes 14.

[0012] The spring assembly 20 adopts a double-layer stacked structure, including an outer spring 21 and an inner spring 22. The outer spring 21 has two first rectangular positioning holes 214 and a first circular positioning hole 216 on its upper part. One side of the outer spring 21 is a first positioning surface 215, on which a first circular positioning boss 217 is provided. The lower part of the outer spring 21 has evenly spaced first spring teeth 212, and the top of the first spring teeth 212 is provided with a first spring contact point 211. The inner spring 22 has two second rectangular positioning holes 224 and a second circular positioning hole 226 on its upper part. One side of the inner spring 22 is a second positioning surface 225, on which a second circular positioning boss 227 is provided. The lower part of the inner spring 22 has evenly spaced first spring teeth 212. The second spring tooth 222 of the cloth has a second spring contact point 221 at its top. The first positioning surface 215 of the outer spring 21 and the second positioning surface 225 of the inner spring 22 are fitted together. After the surface is fitted together, the first circular positioning hole 216 cooperates with the second circular positioning boss 227, and the second circular positioning hole 226 cooperates with the first circular positioning boss 217 to realize the positioning and assembly of the outer spring 21 and the inner spring 22. After the fit is formed, the first rectangular positioning hole 214 and the second rectangular positioning hole 224 are aligned and overlapped. In this state, the first spring contact point 211 and the second spring contact point 221 are staggered and aligned at the same height, realizing a compact space double-row spring multi-contact distribution, which improves the current carrying capacity.

[0013] The top ends of the two positioning rods 32 are also provided with load-bearing rods 33. The housing 10 is also provided with a fixing beam 13, which is located above the buckle mounting groove 11. The housing 10 is also provided with a through hole 15 in the middle. When the locking buckle 30 is installed in the buckle mounting groove 11 of the housing 10, the buckles 31 on both sides of the locking buckle 30 are snapped into the side walls of the loading and unloading holes 14 on both sides of the housing 10. The two positioning rods 32 of the locking buckle 30 pass through the through hole 15. The upper surface of the positioning rod 32 abuts against the lower surface of the fixing beam 13. The load-bearing rod 33 passes through the first rectangular positioning hole 214 and the second rectangular positioning hole 224 and is matched with the first rectangular positioning hole 214 and the second rectangular positioning hole 224 to achieve axial fixation of the spring assembly 20.

[0014] The outer spring piece 21 has a first positioning step 213 on both sides, and the inner spring piece 22 has a second positioning step 223 on both sides. The first positioning step 213 and the second positioning step 223 abut against the bottom plane of the spring piece guide groove 12 to fix the spring piece assembly 20 in the horizontal and vertical downward directions.

[0015] The assembly process of this invention is as follows: After the outer spring piece 21 and the inner spring piece 22 are attached together, the spring piece assembly 20 is formed. The spring piece assembly 20 is aligned with the spring piece guide groove 12 from above the housing 10 and then inserted downward into the housing 10. The front and rear sides of the spring piece assembly 20 abut against the front and rear sides of the spring piece guide groove 12. The first positioning step 213 and the second positioning step 223 in the spring piece assembly 20 abut against the bottom plane of the spring piece guide groove 12, thereby achieving lateral and longitudinal lateral positioning of the spring piece assembly 20. For downward fixing, the locking buckle 30 is pushed in laterally after aligning with the buckle mounting groove 11 on the side of the housing 10. After being pushed in, the buckle 31 of the locking buckle 30 abuts against the side of the loading and unloading hole 14, thus fixing the locking buckle 30. At this time, the positioning rod 32 of the locking buckle 30 passes through the through hole 15, and the load-bearing rod 33 matches the first rectangular positioning hole 214 and the second rectangular positioning hole 224 of the spring assembly 20. After the locking buckle 30 is installed in place, its fixing method inside the housing 10 is as follows: Figure 8 As shown, this achieves overall fixation of the housing 10, the spring assembly 20, and the locking buckle 30. During disassembly, push the inverted buckle 31 inward from the side mounting holes 14 on both sides of the housing 10, causing the inverted buckle 31 to tilt inward and disengage from the side wall of the mounting hole 14. At this time, pull the locking buckle 30 outward to disengage it. After the locking buckle 30 disengages, the spring assembly 20 can be pulled out to disassemble the entire connector.

[0016] The spring assembly 20 of this invention adopts a double-layer stacked design and is designed as a reusable disassembly and assembly structure. This allows users to achieve high current carrying capacity in limited space and conveniently replace and install internal components without damaging parts, which is beneficial to improving on-site assembly and subsequent maintenance efficiency. Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
