Abstract
Description
[0001] This application claims priority to Chinese Patent Application No. 202310971113.5, filed on August 2, 2023, entitled "Connector and Power Distribution System", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of busbar power distribution technology, and more particularly to a connector and power distribution system. Background Technology
[0003] Busbar trunking is a high-current transmission device consisting of metal plates such as copper or aluminum plates as electrode plates, insulating materials as support components, and a housing.
[0004] In power transmission, busbar trunking has significant advantages over traditional cables, such as convenient installation and maintenance, and long service life, and its application is becoming increasingly widespread.
[0005] In power distribution lines, there are usually multiple busbars. Two adjacent busbars are connected by connectors. However, current connectors are relatively complex to assemble and have low connection efficiency. Summary of the Invention
[0006] This application provides a connector and a power distribution system that overcomes the problem of low connection efficiency in busbar trunking and connectors in related technologies. The technical solution is as follows:
[0007] On the one hand, a connector is provided, the connector including a housing and a plurality of connection modules;
[0008] The plurality of connection modules are arranged in the housing;
[0009] Each connection module includes a conductive sheet and a locking mechanism, which clamps the conductive plate of the busbar to the conductive sheet when the connector is connected to the busbar.
[0010] In one possible implementation, the connector further includes a fixed shaft located in the housing, with its two ends respectively fixed to two opposite sidewalls of the housing, and the plurality of connecting modules sequentially sleeved on the fixed shaft.
[0011] In one possible implementation, the locking mechanism includes a rotating wheel that is rotatably fitted over the fixed shaft;
[0012] The locking mechanism is used to clamp the conductive plate of the busbar between the conductive plate and the rotating wheel by rotating the rotating wheel around the fixed axis when the connector is connected to the busbar.
[0013] In one possible implementation, the rotating wheel includes a bushing rotatably fitted over the fixed shaft to insulate and isolate both the conductive sheet and the conductive plate of the busbar groove from the fixed shaft.
[0014] In one possible implementation, the locking mechanism includes a rotating wheel and a sleeve, the rotating wheel including a dial and a bushing, and the sleeve including a tube post and a tube cap;
[0015] The sleeve is rotatably fitted over the bushing, the conductive sheet is fitted over the tube post, and the conductive sheet is located between the tube cap and the actuating disk;
[0016] The locking mechanism is used to clamp the conductive plate and the conductive plate of the busbar between the cap and the locking mechanism when the connector is connected to the busbar. This is achieved by rotating the dial, which causes the sleeve to move axially along the bushing.
[0017] In one possible implementation, the locking mechanism includes a rotating wheel and a sleeve, the rotating wheel including a dial, and the sleeve including a tube post and a tube cap;
[0018] The actuating disc is rotatably fitted over the tube post, the conductive sheet is fitted over the tube post, and the conductive sheet is located between the tube cap and the actuating disc;
[0019] The locking mechanism is used to clamp the conductive sheet and the conductive plate of the busbar between the cap and the dial when the connector is connected to the busbar. This is achieved by rotating the dial, which causes the sleeve to move axially relative to the dial, thus clamping the conductive sheet and the conductive plate of the busbar between the cap and the dial.
[0020] In one possible implementation, the rotating wheel further includes a nut, which is fixed to the actuating disc and sleeved over the tube post of the sleeve, and the nut and the tube post are threaded together.
[0021] In one possible implementation, the actuating disk has a plurality of actuating slots arranged along the circumference of the actuating disk, and the opening and bottom of each actuating slot are distributed radially along the actuating disk, with the opening located at the edge of the actuating disk.
[0022] In one possible implementation, the dials of the connecting modules are paired one-to-one, and a portion of each dial is exposed in the corresponding strip opening.
[0023] In one possible implementation, each connection module further includes a clamping piece, the conductive piece and the clamping piece are arranged side by side, and a slot is formed between the conductive piece and the clamping piece for inserting a conductive plate of the busbar.
[0024] The locking mechanism is used to clamp the conductive plate of the busbar between the conductive plate and the clamping plate when the connector is connected to the busbar.
[0025] In one possible implementation, the housing includes a base and a top cover, the top cover and the base being detachably connected;
[0026] The connector is used to remove the connector of the upper cover and move it from bottom to top when connecting the busbar, so that the multiple conductive plates of the busbar are inserted from top to bottom into the slots formed between the first conductive plate and the clamping plate of each connecting module.
[0027] In one possible implementation, for each connection module, the tops of the conductive sheet and the clamping sheet are bent in a direction away from each other to form a slot with an eight-shaped notch, the tops of the conductive sheet and the clamping sheet being located near the top cover.
[0028] In one possible implementation, the connection module further includes a reset elastic element, which is used to drive the conductive sheet away from the conductive plate when the locking mechanism releases the clamping mechanism between the conductive plate and the conductive sheet of the busbar groove.
[0029] In one possible implementation, the connector further includes a first anti-detachment structure located in the housing and fixed to the base of the housing;
[0030] When the connector is connected to the busbar, the first anti-disconnection structure cooperates with the second anti-disconnection structure of the busbar to pre-install the connector at one end of the busbar.
[0031] In one possible implementation, the first anti-detachment structure is a torsion spring, which is fixed to the top of the base, and the second anti-detachment structure is a boss located on the outer surface of the side wall of the busbar.
[0032] When the connector is connected to the busbar, one arm of the first anti-detachment structure abuts against the inner surface of the side wall of the base, and the other arm of the first anti-detachment structure hangs on the upper surface of the second anti-detachment structure.
[0033] On the other hand, a power distribution system is provided, the power distribution system including a plurality of busbars and the connectors described above;
[0034] The connector is connected between two adjacent busbars, and the portion of each conductive plate of the busbar near its end is clamped with a conductive sheet of a connecting module.
[0035] In the solution disclosed herein, the connector includes multiple connection modules, each of which includes a locking mechanism. Thus, when the connector connects two busbars, the locking mechanism of each connection module can independently lock the conductive plates of the two busbars. Each connection module is independent of the others and does not affect them. The locking process is relatively simple, which can simplify the connection between the connector and the busbar and improve the connection efficiency between the connector and the busbar.
[0036] Moreover, by distributing the force through multiple connection modules, the connector can avoid force concentration and enhance the connector's pressure resistance.
[0037] Furthermore, the locking mechanism of the connecting module includes a rotating wheel. After the connector is inserted into the busbar groove near the end, simply rotating the rotating wheel will connect the connector to the busbar groove, which can further improve the connection efficiency between the connector and the busbar groove.

[0072] This application provides a connector for use in a power distribution system, such as... Figure 1 As shown, the power distribution system includes multiple busbar trunking 100s, multiple connectors 200s, and multiple plug-in boxes. Figure 1 (Not shown in the image). Connector 200 is used to connect two adjacent busbar trunking 100s to extend the power transmission path. The plug-in box, also called a power take-off box, is used to plug into the busbar trunking to draw power. Busbar trunking is a high-current transmission device formed by using metal plates such as copper or aluminum plates as conductive plates, insulating materials as supports, and a metal shell. It has increasingly replaced cables in power transmission trunk line projects.
[0073] For example, power distribution systems can be used in Internet Data Centers (IDCs). Specifically, multiple busbars connected by connectors are arranged in the IDC's server room. External power (such as AC mains power and batteries) is introduced into the IDC server room and connected to one of the busbars. A plug-in box is inserted into the busbar to draw power. The plug-in box includes a power outlet, and cables are plugged into these outlets and routed to the various server racks (such as rack cabinets) in the IDC server room to supply power to each rack.
[0074] This embodiment mainly involves a connector that connects two busbars. The structural features of the connector will be described below.
[0075] like Figure 1 As shown, the connector includes a housing 1, which is specifically an insulating housing. The housing 1 may include a base 11 and a top cover 12. The top cover 12 is detachably installed from the base 11, for example, the top cover 12 is fastened to the top of the base 11.
[0076] like Figure 2 As shown, the connector includes multiple connection modules A, such as... Figure 3 And refer to Figure 1 As shown, multiple connection modules A are arranged in the housing 1.
[0077] Connection module A is installed in housing 1, for example, as Figure 4 As shown, the connector may also include a fixed shaft 2, which is located within the housing 1, with its two ends fixed to two opposite side walls of the housing 1. Figure 4 As shown, multiple connecting modules A are sequentially sleeved on the fixed shaft 2, and the multiple connecting modules A are installed in the housing 1 through the fixed shaft 2.
[0078] The housing 1 is provided with an isolation structure to separate multiple connection modules A. The isolation structure can be an isolation plate to divide the housing 1 into multiple mutually isolated spaces to place multiple connection modules A respectively, so that the multiple connection modules A are mutually insulated and isolated.
[0079] Regarding the number of connection modules A, since each connection module A is used to connect one conductive plate of the busbar trunking, the number of connection modules A is equal to the number of conductive plates included in the busbar trunking.
[0080] For example, a three-phase four-wire busbar trunking system includes four conductive plates; therefore, the number of connection modules A is four. As another example, a three-phase five-wire busbar trunking system includes five conductive plates; therefore, the number of connection modules A is five. See [link to relevant documentation]. Figure 2 As shown.
[0081] For ease of explanation, it can be illustrated as follows: Figure 2As shown, the example uses five connected modules A. The same applies to other values of connected modules A.
[0082] Since connection module A is used to connect a conductive plate of the busbar trunking, therefore, as Figure 2 As shown, the connection module A includes a conductive sheet 3, which is used to contact the conductive plate of the busbar trunking to realize the electrical connection between the connection module A and a conductive plate of the busbar trunking, thereby realizing the electrical connection between the connector and the busbar trunking.
[0083] In one example, connecting module A can achieve close contact between the conductive sheet and the conductive plate by clamping the conductive sheet to the conductive plate. Then, as... Figure 2 As shown, the connection module A also includes a locking mechanism 5, which is used to clamp the conductive plate and conductive sheet 3 of the busbar when the connector is connected to the busbar.
[0084] For example, the locking mechanism 5 can also clamp the conductive plate of the busbar trunking between the conductive sheet 3 and the clamping sheet 4.
[0085] Therefore, as Figure 2 As shown, each connection module A may also include a clamping plate 4, a conductive plate 3, and the clamping plate 4 arranged side by side, and a slot 3-4 is formed between the conductive plate 3 and the clamping plate 4 so that the conductive plate of the busbar can be inserted between the conductive plate 3 and the clamping plate 4.
[0086] The clamping plate 4 and the conductive plate 3 can have the same shape and size, and the material of the clamping plate 4 can also be the same as that of the conductive plate 3, such as both being copper sheets.
[0087] In this way, when the connector is connected to the busbar, the locking mechanism 5 clamps the conductive plate of the busbar between the conductive plate 3 and the clamping plate 4.
[0088] like Figure 2 As shown, the locking mechanism 5 divides the conductive plate 3 into left and right parts, and also divides the clamping plate 4 into left and right parts, so that the left part of the conductive plate 3 and the clamping plate 4 is used to clamp the conductive plate of one busbar, and the right part of the conductive plate 3 and the clamping plate 4 is used to clamp the conductive plate of another busbar. The two busbars are then electrically connected through a connector. (See reference...) Figure 1 As shown, the left end of the connector is connected to one busbar slot, and the right end of the connector is connected to another busbar slot.
[0089] The structural features of the locking mechanism 5 will be described below.
[0090] like Figure 2 As shown, the locking mechanism 5 includes a rotating wheel 51, which is rotatably located in the housing 1. For example, if the connector includes a fixed shaft 2, then the rotating wheel 51 is rotatably sleeved on the fixed shaft 2.
[0091] Continue to refer to Figure 2 As shown, the rotating wheel 51 includes a disc-shaped actuating disk 511, which has a plurality of actuating grooves 5111. The plurality of actuating grooves 5111 are arranged along the circumferential direction of the actuating disk 511, such that the plurality of actuating grooves 5111 are evenly arranged along the circumferential direction of the actuating disk 511.
[0092] The opening and bottom of each actuating groove 5111 are radially distributed along the actuating disk 511, with the opening located at the edge of the actuating disk 511, such as... Figure 2 As shown, this allows technicians to insert a toggle tool into the toggle slot 5111 to rotate the toggle disc.
[0093] like Figure 2 As shown, the locking mechanism 5 is used to clamp the conductive plate of the busbar between the conductive sheet 3 and the clamping sheet 4 by rotating the dial 511 (e.g., around the fixed axis 2) when the connector is connected to the busbar.
[0094] As an example, in a connector including a fixed shaft 2, a conductive sheet 3, a clamping sheet 4, and a disc-shaped actuating plate 511 are sequentially fitted around the fixed shaft 2. When the actuating plate 511 rotates, it can cause the conductive sheet 3 or the clamping sheet 4 to move, thereby reducing the gap between the conductive sheet 3 and the clamping sheet 4, and thus clamping the conductive plate of the busbar groove between the conductive sheet 3 and the clamping sheet 4.
[0095] There are several ways to make the conductive sheet 3 or the clamping sheet 4 move along the axial direction of the fixed shaft 2 while the actuating disk 511 is rotating. Several of these methods will be introduced below.
[0096] (a) The scheme of using the actuating disk 511 to move the clamping plate 4.
[0097] One method for causing the conductive sheet 3 or clamping sheet 4 to move axially along the fixed shaft 2 is that, during the rotation of the actuating disk 511 (e.g., in a first direction), the actuating disk 511 can push the adjacent clamping sheet 4 to move axially along the fixed shaft 2.
[0098] For example, in a connector including a fixed shaft 2, the actuating disk 511 and the fixed shaft 2 are threadedly connected, and the fixed shaft 2 and the housing 1 are fixedly connected. In this way, when the actuating disk 511 rotates around the fixed shaft 2 (e.g., rotates in the first direction), it can move axially along the fixed shaft 2. During the axial movement, the actuating disk 511 can push the clamping plate 4 to move axially along the fixed shaft 2, thereby reducing the gap between the conductive plate 3 and the clamping plate 4, and clamping the conductive plate of the busbar groove therein.
[0099] For example, the rotating wheel 51 also includes a nut 513, which is fixedly connected to the actuating disk 511 and threadedly connected to the fixed shaft 2. Thus, when the actuating disk 511 rotates in the first direction, it drives the nut 513 to rotate around the fixed shaft 2 in the first direction. Since the fixed shaft 2 remains stationary, the nut 513 and the actuating disk 511 move together along the axial direction of the fixed shaft 2, thereby pushing the clamping plate 4 to move along the axial direction of the fixed shaft 2.
[0100] (ii) The scheme of using the cap 522 of the sleeve 52 to push the conductive sheet 3 to move.
[0101] Another method to cause the conductive sheet 3 or the clamping sheet 4 to move axially along the fixed shaft 2 is as follows: Figure 5 As shown, the locking mechanism 5 also includes a sleeve 52, which is bolt-shaped and includes a tube post 521 and a tube cap 522. Figure 5 As shown, the conductive sheet 3 and the clamping sheet 4 are sleeved outside the tube post 521 of the tube sleeve 52 and are located between the tube cap 522 of the tube sleeve 52 and the actuating disk 511 of the rotating wheel 51.
[0102] In this way, when the connector is connected to the busbar, the actuating disk 511 rotates without moving, thereby driving the sleeve 52 to move axially. The cap 522 of the sleeve 52 pushes the adjacent conductive plate 3 to move, clamping the conductive plate of the busbar between the conductive plate 3 and the clamping plate 4.
[0103] The method by which the dial 511 rotates without moving can be, for example: Figure 1 As shown, the upper cover 12 of the housing 1 has multiple strip openings 121. The actuating disk 511 of each connecting module A can be locked in the corresponding strip opening 121, thereby enabling the actuating disk 511 to rotate without moving, thus causing the sleeve 52 to move.
[0104] There are several ways to move the sleeve 52 during the rotation of the actuating disk 511, some of which will be introduced below.
[0105] (1) A scheme to rotate the dial 511 to move the sleeve 52.
[0106] like Figure 5 As shown, the actuating disc 511 of the rotating wheel 51 is sleeved on the outside of the tube post 521, and the actuating disc 511 and the tube post 521 are threadedly connected. In this way, when the actuating disc 511 rotates, it can cause the sleeve 52 to rotate and move, thereby pushing the conductive plate 3 to move, and then clamping the conductive plate of the busbar groove between the conductive plate 3 and the clamping plate 4.
[0107] (2) Another option is to rotate the dial 511 to move the sleeve 52.
[0108] like Figure 6 As shown, the rotating wheel 51 also includes a nut 513, which is fixedly connected to the actuating disk 511. The nut 513 is sleeved on the outside of the tube post 521 of the sleeve 52, and the nut 513 is threadedly connected to the tube post 521 (the tube post 521 has external threads).
[0109] In this way, as the dial 511 rotates, the sleeve 52 can move towards the dial 511, such as... Figure 6 As shown, this pushes the conductive sheet 3 to move closer to the clamping sheet 4, thereby reducing the gap between the conductive sheet 3 and the clamping sheet 4, and clamping the conductive plate of the busbar groove therein.
[0110] (3) Another option is to rotate the dial 511 to move the sleeve 52.
[0111] like Figure 7 As shown, the rotating wheel 51 also includes a bushing 512, which is fixed to the surface of the dial 511. Figure 7 As shown, the sleeve 52 is fitted over the bushing 512, and the tube post 521 of the sleeve 52 is threadedly connected to the bushing 512.
[0112] For example, sleeve 52 has internal threads, and bushing 512 has external threads. Sleeve 52 is fitted over bushing 512, and the two are connected by threads.
[0113] In this way, when the dial 511 rotates, the bushing 512 rotates along with it. Since the bushing 512 is threadedly connected to the sleeve 52, the bushing 512 and the dial 511 only rotate without moving, so the sleeve 52 can move axially.
[0114] Of course, in the design where the rotating wheel 51 includes the actuating disc 511 and the bushing 512, the rotating wheel 51 may also include a nut 513, such as... Figure 8 As shown, the sleeve 52 is fitted over the bushing 512, and the nut 513 is fitted over the tube post 521 of the sleeve 52, and the nut 513 and the tube post 521 are threaded together.
[0115] As described above, the nut 513 and the actuating disc 511 are fixedly connected, for example, as... Figure 9 As shown, the first surface of the actuating disc 511 has a groove 5112, and the nut 513 is embedded in the groove 5112. Figure 9 As shown, the bushing 512 is also fixed in the groove 5112.
[0116] Figures 5 to 8 In solutions where the connector does not include the fixed shaft 2, the structural diagram of the locking mechanism 5 is shown below. Figures 10 to 12 As shown, taking the connector including the fixed shaft 2 as an example, the structural features of the locking mechanism 5 are summarized as follows:
[0117] in, Figure 10 This is a schematic diagram of a locking mechanism 5 fitted around a fixed shaft 2. Figure 11 This is a schematic diagram of a connecting module A fitted around a fixed shaft 2. Figure 12 This is a schematic diagram of a structure in which multiple connecting modules A are arranged side by side and fitted around a fixed shaft 2.
[0118] like Figure 11 As shown, the connecting module A includes a conductive sheet 3, a clamping sheet 4, and a locking mechanism 5, as follows: Figure 10 As shown, the locking mechanism 5 includes a rotating wheel 51 and a sleeve 52. The rotating wheel 51 includes an actuating disc 511, a bushing 512, and a nut 513. The bushing 512 is rotatably fitted over the fixed shaft 2, and the nut 513 is fixed to the actuating disc 511. The sleeve 52 is rotatably fitted over the bushing 512. Figure 10 As shown, the conductive sheet 3 and the clamping sheet 4 are both sleeved outside the tube post 521 of the sleeve 52, and the conductive sheet 3 and the clamping sheet 4 are located between the tube cap 512 and the nut 513 of the sleeve 52.
[0119] like Figure 10 As shown, the bushing 512 is rotatably fitted over the fixed shaft 2. The bushing 512 can achieve insulation isolation between the conductive sheet 3 and the fixed shaft 2, and can also achieve insulation isolation between the conductive plate of the busbar and the fixed shaft 2.
[0120] like Figure 12 As shown, multiple connecting modules A are arranged side by side around the fixed shaft 2, and each connecting module A is independent of the others.
[0121] The above describes the structural features of the locking mechanism 5 of the connecting module A. Other features of the connector will be described below.
[0122] In one example, while the dial 511 is being rotated, a technician can remove the top cover 12 from the base 11, exposing the dial 511, and then rotate the dial 511 through the dial slot 5111.
[0123] In another example, such as Figure 13 As shown, the housing 1 has multiple strip openings 121, and each strip opening 121 corresponds one-to-one with a multiple dial 511 of the connecting module A, with a portion of each dial 511 exposed in the corresponding strip opening 121. In this way, when the dial 511 is rotated, it is not necessary to remove the top cover 12 from the base 11.
[0124] A portion of the dial 511 is exposed in the corresponding strip opening 121, for example, as Figure 13 As shown, a portion of the dial 511 extends out of the corresponding strip opening 121.
[0125] As described above, when the locking mechanism 5 rotates (e.g., in the first direction), it reduces the gap between the conductive sheet 3 and the clamping sheet 4, thus clamping the conductive plate of the busbar trough between the conductive sheet 3 and the clamping sheet 4. When the locking mechanism 5 rotates in the opposite direction (referred to as rotating in the second direction), it releases the clamping effect of the conductive sheet 3 and the clamping sheet 4 on the conductive plate of the busbar trough.
[0126] When the locking mechanism 5 releases the clamping action of the conductive sheet 3 and the clamping sheet 4 on the conductive plate of the busbar groove, in order to reset the conductive sheet 3 and the clamping sheet 4, accordingly, as shown in the figure... Figure 11 As shown, the connecting module A also includes a reset elastic element 6, which is located between the conductive sheet 3 and the clamping sheet 4.
[0127] The reset elastic element 6 is used to drive the conductive sheet 3 away from the conductive plate when the locking mechanism 5 releases the clamping of the conductive plate and the conductive sheet of the busbar groove. For example, when the locking mechanism 5 releases the clamping of the conductive sheet 3 and the clamping piece 4 on the conductive plate, the conductive sheet 3 and the clamping piece 4 are driven away from each other to form a slot 3-4 for the conductive plate to be inserted.
[0128] Since both the conductive sheet 3 and the clamping sheet 4 are divided into left and right parts by the locking mechanism 5 to clamp the conductive plates of the two busbar slots, each connection module A can include at least one pair of reset elastic elements 6, such as... Figure 2 As shown, a portion of the reset elastic element 6 is located on the left side of the locking mechanism 5 and is sandwiched between the conductive sheet 3 and the clamping sheet 4, while another portion of the reset elastic element 6 is located on the right side of the locking mechanism 5 and is sandwiched between the conductive sheet 3 and the clamping sheet 4.
[0129] In one example, the reset elastic element 6 can be as follows: Figure 12 The torsion spring shown has its helical portion suspended between the conductive sheet 3 and the clamping sheet 4, with its two arms resting against the surfaces of the conductive sheet 3 and the clamping sheet 4, respectively.
[0130] Thus, when the locking mechanism 5 locks the conductive plate of the busbar groove between the conductive sheet 3 and the clamping sheet 4, the torsion spring is in a compressed state. When the locking mechanism 5 releases the conductive sheet 3 and the clamping sheet 4 from locking the conductive plate, the distance between the conductive sheet 3 and the clamping sheet 4 increases under the action of the torsion spring, so as to form a slot 3-4 for the conductive plate to be inserted.
[0131] In another example, the reset elastic element 6 can also be a U-shaped spring or a V-shaped spring.
[0132] In another example, the reset elastic element 6 can also be a spring, which can be vertically connected between the conductive sheet 3 and the clamping sheet 4.
[0133] In this embodiment, the specific structural form of the reset elastic element 6 is not limited. As long as the rotating wheel 51 rotates in the second direction, it can cause the conductive sheet 3 and the clamping sheet 4 to move away from each other.
[0134] The second direction is opposite to the first direction described above; for example, one is clockwise and the other is counterclockwise.
[0135] When the actuating disk 511 rotates in the first direction, it can lock the conductive plate of the busbar groove between the conductive sheet 3 and the clamping sheet 4. When the actuating disk 511 rotates in the second direction, it can release the locking of the conductive sheet 3 and the clamping sheet 4 onto the conductive plate.
[0136] The connector is installed in a busbar duct, and can be pushed into one end of the busbar duct from bottom to top. For example, busbar ducts are typically mounted at a relatively high position above the ground. When a technician connects the connector to the busbar duct, such as... Figure 14 As shown, the upper cover 12 of the housing 1 can be removed from the base 11 first. Then, a technician or a robotic arm can manually remove the connector of the upper cover 12 and move it from bottom to top. During this process, multiple conductive plates of the busbar groove are inserted from top to bottom into the slots 3-4 formed between the conductive plates 3 and clamping plates 4 of each connecting module A.
[0137] To facilitate the insertion of the busbar's conductive plate into the slots 3-4 between the conductive sheet 3 and the clamping sheet 4, correspondingly, as... Figure 15 As shown, for each connection module A, the tops of its conductive sheet 3 and clamping sheet 4 are bent in a direction away from each other to form a slot 3-4 with a V-shaped opening, wherein the tops of the conductive sheet 3 and clamping sheet 4 are located near the top cover 12.
[0138] like Figure 15 As shown, the top of the conductive sheet 3 is bent away from the clamping sheet 4, and the top of the clamping sheet 4 is bent away from the conductive sheet 3, so that the slot of the slot 3-4 is V-shaped and has a guiding function.
[0139] In this way, the conductive plate of the busbar trunking can be quickly and accurately inserted into the slots 3-4 between the conductive plate 3 and the clamping plate 4, thereby improving the connection efficiency between the connector and the busbar trunking.
[0140] After each conductive plate of the busbar trunking is fully inserted into the slots 3-4 between the conductive plates 3 and clamping plates 4 of each connecting module A, the technician can then move the actuating discs 511 of each connecting module A to lock the conductive plates in their respective slots 3-4. Once all the conductive plates are locked, the top cover 12 is then placed on the base 11.
[0141] During the process of tightening the conductive plate of the busbar trunking, another technician needs to hold the connector continuously, which is inconvenient. To further simplify the connection and assembly of the connector and the busbar trunking, correspondingly, such as Figure 16 As shown, the connector also includes a first anti-disengagement structure 7; the first anti-disengagement structure 7 is located in the housing 1 and fixed on the base 11 of the housing 1. When the connector is connected to the busbar, as... Figure 17 As shown, the first anti-disconnection structure 7 cooperates with the second anti-disconnection structure 101 of the busbar trunking to allow the connector to be pre-installed at one end of the busbar trunking.
[0142] In one example, the first anti-detachment structure 7 can be a torsion spring, such as... Figure 17 As shown, the torsion spring is fixed to the top of the base 11, and the second anti-detachment structure 101 is a boss located on the outer surface of the side wall of the busbar trough. (Continue to refer to...) Figure 12 As shown, when the connector is connected to the busbar, one arm of the first anti-detachment structure 7 abuts against the inner surface of the side wall of the base 11, and the other arm of the first anti-detachment structure 7 hangs on the upper surface of the second anti-detachment structure 101.
[0143] In this way, after the connector is inserted into one end of the busbar trough from bottom to top, the first anti-detachment structure 7 is attached to the second anti-detachment structure 101 of the busbar trough 100, which can prevent the connector from falling out of the busbar trough. It also eliminates the need for technicians to hold the connector continuously, thereby simplifying the connection between the connector and the busbar trough.
[0144] like Figure 17 As shown, the first anti-detachment structure 7 can be a torsion spring. The top of the base 11 has a torsion spring shaft, and the helical part of the torsion spring is sleeved on the torsion spring shaft. One arm of the torsion spring abuts against the side wall of the base 11, and the other arm, as shown... Figure 17 As shown, it is used to abut against the outer surface of the side wall of the busbar trunking and hang on the second anti-detachment structure 101 of the busbar trunking.
[0145] like Figure 16 and Figure 17 As shown, the number of the first anti-detachment structure 7 can be four, such as... Figure 16 As shown, four first anti-detachment structures 7 are arranged at the four corners of the base 11.
[0146] The above describes the connector being pushed into the busbar trough from bottom to top. Of course, the connector and the busbar trough can also be at the same height, with the connector inserted horizontally into the busbar trough. This embodiment does not limit this. Considering that the busbar trough is mounted at a certain height, the connection method of pushing the connector into the busbar trough from bottom to top is more convenient.
[0147] Based on the above, the connector includes multiple connection modules, each of which includes a locking mechanism. In this way, when the connector connects two busbars, the locking mechanism of each connection module can independently lock the conductive plates of the two busbars. Each connection module is independent of the others and does not affect them. The locking process is relatively simple, which can simplify the connection between the connector and the busbar and improve the connection efficiency between the connector and the busbar.
[0148] Moreover, by distributing the force through multiple connection modules, the connector can avoid force concentration and enhance the connector's pressure resistance.
[0149] Furthermore, the locking mechanism of the connecting module includes a rotating wheel. After the connector is inserted into the busbar groove near the end, simply rotating the rotating wheel will connect the connector to the busbar groove, which can further improve the connection efficiency between the connector and the busbar groove.
[0150] This embodiment also provides a power distribution system, such as Figure 1 As shown, the power distribution system includes multiple busbar trunking 100 and the aforementioned connector 200. The connector 200 is connected between two adjacent busbar trunking 100, and the portion of each conductive plate of the busbar trunking 100 near its end is clamped with a conductive piece 3 of a connecting module A, such as between a conductive piece 3 of a connecting module A and a clamping piece 4.
[0151] The specific structural features of the connector 200 of the power distribution system are described above and will not be repeated here.
[0152] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this application should be included within the protection scope of this application.
