[0031] Example 1

[0032] Reference Figure 1-Figure 3 , provides a schematic diagram of the overall structure of a busbar system, such as Figure 1 A busbar system comprises a busbar 101, a cover plate 102 arranged on the upper and lower sides of the busbar 101, and a side plate 103 connecting the two cover plates 102, wherein the side plates 103 are arranged on the left and right sides of the busbar 101; a connecting assembly 200 comprises end connectors 201 arranged at both ends of the busbar 101, a first connecting plate 202 and a second connecting plate 203 arranged on the outside of the end connector 201, and an end stopper 204 connected to the outside of the first connecting plate 202 or the second connecting plate 203, a connecting joint 205 is connected to the end connector 201, and a rubber ring 207 is attached to the outside of the end connector 201; and a sealing member 700, comprising a sealing pad 701 attached to the inner side of the end connector 201, a side sealing pad plate 702 arranged on the inner side of the end stopper 204, and a sealing strip 703 arranged on the outer side of the end stopper 204, wherein a self-tapping screw sleeve 704 is threadedly connected to the end connector 201.

[0033] Specifically, the main structure of the present invention includes a busbar body 100. In the present embodiment, the busbar body 100 includes a busbar 101, which is composed of a plurality of rectangular block copper plates in the shape of long flat strips. Then, cover plates 102 are abutted on the upper and lower sides of the busbar 101. The two cover plates 102 are arranged parallel to each other, and the side surface of the busbar 101 is perpendicular to the inner surface direction of the cover plate 102. Then, two side plates 103 are connected between the two cover plates 102. The side plates 103 are arranged perpendicular to the inner surface of the cover plate 102, and a space for receiving the busbar 100 is formed between the two side plates 103 and the two cover plates 102. At the same time, the side plates 103 are arranged in contact with the busbar 101, and the side plates 103 are connected to the cover plates 102, so that the cover plates 102 and the side plates 103 can receive the busbar 101.

[0034] Furthermore, the main structure also includes a connection assembly 200. In this embodiment, the connection assembly 200 includes end connectors 201 connected to both ends of the cover plate 102. The end connectors 201 are bolted to both ends of each cover plate 102. One end of each end connector 201 extends outward from the end of the cover plate 102. Then, an end stopper 204 is connected between the two end connectors 201 located on the same side of the cover plate 102. There are two end stops 204, and each end stopper 204 is tightly connected to the end connector 201. After the end block 204 is connected to the end connector 201, the outwardly extending and connected configuration of the end connector 201 and the end block 204 also increases a certain degree of sealing, and the outer wall of the end block 204 is flush with the side wall of the end connector 201. At this time, an outlet for the busbar 101 to extend out is formed between the two end connectors 201 and the end block 204. This outlet is only for the busbar 101 to extend out, and then the end connector 201 and the end block 204 preliminarily seal the space formed between the two side plates 103 and the two cover plates 102.

[0035] Furthermore, a rubber ring 207 is attached to the outside of the end connector 201, and the rubber ring 207 further seals and protects the interior.

[0036] Furthermore, the busbar 101 extends outward through an outlet formed between the end stopper 204 and the end connector 201, and a connection joint 205 is fixed at the end, and the connection joint 205 is integrated with the busbar 101. In order to protect the connection joint 205, a seal 700 is provided between the end connector 201 and the end stopper 204. In this embodiment, the seal 700 includes a sealing gasket 701 attached to the inner side of the end connector 201, and a rubber ring 207 is also provided outside the end connector. The rubber ring 207 is connected to the sealing gasket 701 as a whole. When the operator installs the sealing gasket 701, the rubber ring 207 is installed. The ring 207 is sleeved on the end connector 201. At this time, the sealing gasket 701 is located on the inner side of the end connector 201. At the same time, a side sealing plate 702 is also attached to the inner side of the end stopper 204. After the end stopper 204 is connected to the end connector 201, the side sealing plate 702 abuts against the bottom surface of the sealing gasket 701 to form a tight sealing structure. The side sealing plate 702 and the sealing gasket 701 jointly seal the gap between the end connector 201 and the end stopper 204, thereby sealing the protruding end of the busbar 101; then a sealing strip 703 is also attached to the outer side of the end stopper 204.

[0037] Furthermore, the material of the end connector 201 is cast aluminum, and a connecting hole is opened on the end connector 201, and a self-tapping screw sleeve 704 is connected in the connecting hole. The self-tapping screw sleeve will open a thread on the inner wall of the connecting hole when it is screwed into the hole. In terms of process, when manufacturing the end connector 201, the operator reserves a connecting hole at the corresponding position of the end connector 201, and then the operator screws the self-tapping screw sleeve 704 into the connecting hole through a special tool. Since the self-tapping screw sleeve 704 is a steel product, the strength is greatly improved. After the screw is screwed in, the thread will not slip, thereby increasing the installation stability of the screw.

[0038] Furthermore, a first connecting plate 202 and a second connecting plate 203 are connected to the outer side of the end stop block 204. The first connecting plate 202 is a joint side plate (N side), and the second connecting plate 203 is a joint side plate (PE side). The first connecting plate 202 is arranged at the left end of the connecting joint 205, and the second connecting plate 203 is arranged at the right end of the connecting joint. The first connecting plate 202 and the second connecting plate 203 are symmetrically arranged about the vertical midpoint line.

[0039] Specifically, the two cover plates 102 are first connected to one of the side plates 103, and a U-shaped storage space is formed between the two cover plates 102 and the side plates 103. Then the operator puts the bus bar 101 in, and makes the side plate 103 abut against the surface of the bus bar 101. Then the operator connects the other side plate 103 to the other end of the two cover plates 102. At this time, the cover plates 102 and the side plates 103 jointly protect and support the bus bar 101. Then the operator first sets one of the rubber rings 207 on the end connector 201, and then the operator screws the two end blocks 204 with the end connector 201. Bolt connection, at this time, the side sealing gasket 702 abuts against the sealing gasket 701, and is squeezed and elongated. After that, the operator connects the end connector 201 to the outer surface of the cover plate 102, and then the operator connects the other end connector 201 to the end stopper 204 and the cover plate 102. At this time, the sealing gasket 701 and the side sealing gasket 702 together form a sealing structure to prevent external dust or liquid from entering the busbar 101, thereby protecting the busbar 101. Then the operator connects the first connecting plate 202 and the second connecting plate 203 to the two end stops 204 respectively. At this time, the assembly of the entire busbar system is completed.

[0040] Example 2

[0041] Reference Figure 4 and Figure 5 The embodiment is different from the first embodiment in that a sealing assembly 300 is further provided between the first connecting plate 202 and the second connecting plate 203. The sealing assembly 300 can seal and protect the connecting joint 205 to prevent external dust or liquid from damaging the connecting joint 205 or the internal bus duct. The sealing assembly 300 includes a sealing block 301 connected to the lower surface of the first connecting plate 202, a sealing rod 302 provided at the upper end of the sealing block 301, and a sealing rod 302 provided on the first connecting plate 202 to cooperate with the sealing rod 302. A through hole 303 is formed between the first connecting plate 202 and the second connecting plate 203, wherein a vertically arranged frame plate 304 is connected between the first connecting plate 202 and the second connecting plate 203, the side wall of the sealing block 301 abuts against the inner wall of the frame plate 304, an elastic member 305 is provided between the sealing rod 302 and the first connecting plate 202, a driving component 400 for driving the sealing block 301 to slide is provided on the second connecting plate 203, and a blocking plate 306 is provided on the inner side of the second connecting plate 203, and the upper end edge height of the blocking plate 306 is higher than the lower end edge height of the sealing block 301.

[0042] Specifically, in the present embodiment, the sealing assembly 300 includes a sealing block 301 connected to the inner side of the first connecting plate 202, the end stopper 204 is in the shape of a rectangular block, and the sealing block 301 slides in the vertical direction, and a sealing rod 302 is fixed to the upper end of the sealing block 301, the sealing rod 302 is arranged in the vertical direction, and then a through hole 303 cooperating with the sealing rod 302 is opened on the first connecting plate 202, so that the sealing rod 302 can extend outward from the first connecting plate 202 through the through hole 303, and then the operation process of extending or inserting the connecting rod into the through hole 303 realizes the vertical movement of the sealing block 301, and then in order to make the initial position of the sealing block 301 blocked at the front end of the connecting joint 205, an elastic member 305 is also connected between the sealing rod 302 and the first connecting plate 202, and the elastic member 305 in the present embodiment is a tension spring 403, so that the sealing block 301 can be pushed downward all the time, so that the initial position of the sealing block 301 is blocked in front of the connecting joint 205.

[0043] Furthermore, in order to seal the side wall direction of the connecting joint 205, a frame plate 304 is connected to the inner side of the first connecting plate 202 and the second connecting plate 203, and the frame plate 304 is arranged in the vertical direction. There are two frame plates 304 on the first connecting plate 202 and the second connecting plate 203, and each frame plate 304 is perpendicular to the inner wall direction of the first connecting plate 202 or the second connecting plate 203. At the same time, the frame plate 304 is parallel to the side wall direction of the sealing block 301, and the distance between the two frame plates 304 on the second connecting plate 203 is slightly greater than the distance between the two frame plates 304 on the first connecting plate 202. The distance between them, and then after the first connecting plate 202 and the second connecting plate 203 are connected, the frame plates 304 abut against each other to form a sealing structure. At the same time, the design of unequal spacing between the frame plates 304 makes it convenient to locate the position between the first connecting plate 202 and the second connecting plate 203 when the first connecting plate 202 and the second connecting plate 203 are both connected to the end connecting piece 201. During installation, it is only necessary to abut the frame plates 304 on the first connecting plate 202 against the frame plates 304 on the second connecting plate 203 accordingly to complete the determination of the position between the first connecting plate 202 and the second connecting plate 203.

[0044] Furthermore, because the initial position of the sealing block 301 only blocks the front of the connecting joint 205, there is still a gap between the sealing block 301 and the second connecting plate 203, and in order to achieve complete sealing, a blocking plate 306 is fixed on the inner wall of the second connecting plate 203. The blocking plate 306 is arranged in the vertical direction, and when the sealing block 301 is in the initial position, the inner wall of the end block 204 abuts against the outer wall of the blocking plate 306, and the height of the blocking plate 306 is higher than the height of the lower surface of the sealing block 301 when it is in the initial position, and under the joint action of the blocking plate 306, the frame plate 304 and the sealing block 301, the sealing protection of the connecting joint 205 is achieved.

[0045] Furthermore, in order to realize the automatic lifting operation of the end block 204 during connection, a driving component 400 for driving the end block 204 to slide upward is also provided on the second connecting plate 203, and then during connection, the driving component 400 lifts the end block 204 to expose the connecting joint 205, and then after disassembly, the driving component 400 is reset, and the elastic member 305 pushes the end block 204 downward, so as to realize the resetting of the end block 204 and continue to maintain the sealing state.

[0046] The rest of the structure is the same as that of Example 1.

[0047] Operation process: When external connection is not required, the sealing block 301, driven by the elastic member 305, works together with the blocking plate 306 and the frame plate 304 to seal and protect the connection joint 205, blocking external dust or liquid and maintaining a sealed and protected state; when the bus duct needs to be connected externally, the operator uses the driving component 400 to lift the sealing block 301 upwards, exposing the connection joint 205, and the connection operation can be performed.

[0048] Example 3

[0049] Reference Figure 4 and Figure 5 , this embodiment is different from the above embodiments in that: the driving component 400 includes a driving plate 401 that is slidably connected to the inner bottom surface of the second connecting plate 203 in the horizontal direction, and two lifting plates 402 arranged parallel to each other are provided on the driving plate 401, and the lifting plates 402 are arranged near the inner wall of the frame plate 304, and the driving plate 401 extends outward from the second connecting plate 203, and a spring 403 is arranged at the lower end of the driving plate 401, and a first inclined surface 404 is provided on the lifting plate 402, and a second inclined surface 405 is provided on the side of the sealing block 301 close to the lifting plate 402, and the first inclined surface 404 is arranged toward the sealing block 301, and the second inclined surface 405 has the same inclination angle as the first inclined surface 404.

[0050] Specifically, in the present embodiment, the driving component 400 includes a driving plate 401 which is slidably connected to the inner bottom surface of the second connecting plate 203 in a horizontal direction. The driving plate 401 is in the shape of a rectangular flat plate and is in contact with the frame plate 304 on both sides of the driving plate 401. At the same time, two mutually parallel lifting plates 402 are provided on the upper surface of the driving plate 401. The lifting plates 402 are both arranged perpendicular to the upper surface of the driving plate 401, and the two lifting plates 402 are both arranged near the side of the driving plate 401. At the same time, one end of the driving plate 401 away from the sealing block 301 extends outward from the outside of the second connecting plate 203. This design enables the driving plate 401 to drive the lifting plates 402 to slide and abut against the sealing block 301 as long as the outside squeezes or pushes the driving plate 401 to slide into the connecting plate.

[0051] Preferably, a spring 403 is also connected to the lower end of the drive plate 401, and the spring 403 connects the drive plate 401 to the inner surface of the second connecting plate 203. In the present embodiment, the spring 403 is a tension spring 403, and thus when the drive plate 401 is not pushed by an external force, the spring 403 is in its original length state, and thus one end of the drive plate 401 can be kept in an outwardly extending state. This design also allows the drive plate 401 to automatically reset after the connection is disassembled, and the abutment between the drive plate 401 and the sealing block 301 is immediately cancelled, thereby ensuring that the sealing block 301 is reset and sealed once the connection is not in use.

[0052] Furthermore, in order to push the end stopper 204 upward by using the lifting plate 402 after the driving plate 401 moves, a first inclined surface 404 is provided at the upper end of the lifting plate 402, and the first inclined surface 404 faces the direction of the sealing block 301. At the same time, a second inclined surface 405 is provided at the lower end of the sealing block 301, and the second inclined surface 405 faces the direction of the lifting plate 402. The first inclined surface 404 and the second inclined surface 405 have the same inclination angle, so that when the lifting plate 402 moves toward the sealing block, the end stopper 204 can be pushed upward by using the lifting plate 402. When moving in the direction of 301, the first inclined surface 404 abuts against the second inclined surface 405, and then as the lifting plate 402 slides, the first inclined surface 404 applies force to the second inclined surface 405. Due to the inclined design and the design that the sealing block 301 can only move in the vertical direction, the sealing block 301 will gradually slide upward, and then the connecting joint 205 is exposed. At the same time, the design of the lifting plate 402 on both sides can ensure that the sealing block 301 is lifted up without affecting the exposure of the connecting joint 205.

[0053] The remaining structures are the same as those in Example 2.

[0054] Operation process: When performing the connection operation, the operator puts the external terminal into contact with the driving plate 401, and then the driving plate 401 moves inward, and the lifting plate 402 lifts the sealing block 301 upward. After lifting, the connecting connector 205 is exposed, and the connection operation can be performed. This design only needs to push the driving plate 401 to automatically push out the sealing block 301.

[0055] Example 4

[0056] Reference Figure 6 and Figure 7 , this embodiment is different from the above embodiments in that: an extension joint 206 is connected to the connecting joint 205, and an extension component 500 for driving the extension joint 206 to extend is provided between the lower end of the extension joint 206 and the driving plate 401, and the extension component 500 includes a slide groove 501 provided on the connecting plate, a gear 502 rotatably connected in the slide groove 501, and a rack 503 meshed with the gear 502, wherein there are two racks 503 and they are respectively provided on both sides of the gear 502, wherein one rack 503 is connected to the lower end of the driving plate 401, and the other rack 503 is connected to the lower end of the extension joint 206, and an operating groove 504 is provided on the first connecting plate 202.

[0057] Specifically, in order for the operator to connect the connecting joint 205, an extension joint 206 is also slidably connected to the connecting joint 205. The shape of the extension joint 206 is the same as that of the connecting joint 205, and in the initial state, the extension joint 206 is connected to the connecting joint 205, and then a protruding component 500 is further provided between the extension joint 206 and the driving plate 401. In this embodiment, the protruding component 500 includes a slide groove 501 provided on the second connecting plate 203, and then a gear 502 is rotatably connected in the slide groove 501, and the gear 502 is rotatably connected in the slide groove 501. The rotation plane of the wheel 502 is set horizontally, and then two racks 503 are slidably connected in the slide groove 501. The two gears 502 slide in the horizontal direction, and one of the racks 503 is meshed with one side of the gear 502, and the other rack 503 is meshed with the other side of the gear 502. Then, after the gear 502 rotates, the two racks 503 will slide in the direction away from or close to each other. At the same time, one of the racks 503 is connected to the lower end of the driving plate 401, and the other rack 503 is connected to the lower end of the extension joint 206.

[0058] Furthermore, in order to facilitate the operator to connect the extension joint 206 with the external end during the connection operation, an operation groove 504 is also provided on the first connecting plate 202. The operation groove 504 connects the inner and outer surfaces of the first connecting plate 202, and the operation groove 504 is provided at one end of the first connecting plate 202 away from the sealing block 301, which will not affect the sealing structure. At the same time, the operator can operate through the operation groove 504 when making the connection, which is more convenient and quick.

[0059] The rest of the structure is the same as that of Example 3.

[0060] Operation process: When the driving plate 401 moves toward the second connecting plate 203, it will drive the rack 503 to slide, and then the slide will drive the gear 502 to rotate after moving, and after rotating, it will drive the other rack 503 to slide, and then drive the extension joint 206 to move outward. At this time, the extension joint 206 extends outward, thereby extending the length of the connection, and then the operator performs the connection operation through the operating slot 504.

[0061] Example 5

[0062] Reference Figure 8 , this embodiment is different from the above embodiment in that: an abutting plate 600 is provided at one end of the side plate 103 close to the cover plate 102, a first wavy groove 601 is provided on the abutting plate 600, a second wavy groove 602 matching the first wavy groove 601 is provided on the cover plate 102, a heat sink 603 is provided on the outer surface of the side plate 103, and a heat sink 604 is provided on the heat sink 603.

[0063] Specifically, in order to make the connection between the side panel 103 and the cover plate 102 more stable, abutment plates 600 are provided at both ends of the side panel 103 close to the cover plate 102, and the abutment plates 600 are arranged perpendicular to the surface of the side panel 103, and then a first wave groove is also provided on the side of the abutment plate 600 close to the cover plate 102. The first wave groove has a cross-sectional shape of a plurality of semicircular arcs connected at the ends, and each adjacent semicircular arc is symmetrically arranged with respect to each other, and then a second wave groove matching with the first wave groove is provided on the cover plate 102. When installing the side panel 103, the first wave groove and the second wave groove match with each other, and the installation can be completed at this time. This design can position the installation of the side panel 103 on the cover plate 102, and at the same time, because of the semicircular groove, the connecting part has a more stable sealing effect.

[0064] Furthermore, a heat sink 603 is provided on the outer surface of the side panel 103. There are several heat sinks 603, and they are all arranged along the length direction of the side panel 103. The longitudinal section of the heat sink 603 is triangular, and the top of the heat sink 603 is opened into an arc surface. Then, a heat sink protrusion 604 is fixed on the outer surface of each heat sink 603. The heat sink protrusion 604 is in the shape of a long strip and is equidistantly arranged on the surface of the heat sink 603. At the same time, the material is copper-aluminum alloy. The copper-aluminum alloy itself has high strength and can also transmit and dissipate internal heat.

[0065] The rest of the structure is the same as that of Example 1.

[0066] Specifically, when installing the side panel 103, the first wave groove cooperates with the second wave groove, and the installation is completed at this time. This design can position the installation of the side panel 103 on the cover plate 102. At the same time, due to the semicircular groove, the connection part has a more stable sealing effect. At the same time, the heat dissipation block 603 and the heat dissipation protrusion 604 on the side panel 103 can increase the external surface area of ​​the side panel 103, thereby increasing the heat conduction area, so that more heat can be dissipated outward, making the heat dissipation effect better.
