Description

Technical Field

[0001] The utility model relates to the technical field of plug-in boxes, in particular to a fast-insertion intensive bus duct plug-in box. Background Art

[0002] The main function of the bus duct plug-in box is to extend the bus duct branch line, disconnect and protect the circuit through the circuit breaker in the plug-in box, so as to divert the current of the bus duct main line to the electrical equipment.

[0003] The bus duct plug-in box is a common feeder method in the bus duct system, which is generally composed of a box body, an air switch, and a pin. Its function is to distribute the current of the bus duct to various electrical equipment, and it is very convenient to use and maintain. When the electrical equipment needs to be powered off or repaired, the air switch in the plug-in box can be disconnected without disconnecting the entire line. If the number of electrical equipment increases later, the original plug-in box can be directly unplugged and replaced with a plug-in box with a higher current. This design enables the bus duct system to flexibly adapt to different power needs while ensuring safety and reliability.

[0004] The connection methods between the bus duct and the junction box are mainly divided into direct plug-in method, junction box connection method and bus duct joint connection method. Among them, the advantages of direct plug-in method are simple connection, convenient installation, and short connecting cable, but the plug-in is easy to fall off; the advantage of junction box connection method is that it is not easy to fall off and the connection distance is long, but due to multiple connection operations, maintenance and inspection are required; the advantage of bus duct joint connection method is stable connection and long connection distance, but due to the need for special joints, the cost is higher.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0036] See also Figures 1 to 6 In an embodiment of the utility model, a fast-insertion intensive bus duct plug-in box comprises a plug-in box 1 and a bus duct 2 which can be detached from the plug-in box 1, a first conductive copper bar 101 is arranged on the plug-in box 1, a second conductive copper bar 201 is arranged on the bus duct 2, and the first conductive copper bar 101 and the second conductive copper bar 201 can be staggered and plugged;

[0037] The plug-in box 1 is provided with a locking assembly, and the bus duct 2 is provided with a Z-shaped card plate 3. During the process of misaligned plugging of the first conductive copper bar 101 and the second conductive copper bar 201, the locking assembly will cooperate with the Z-shaped card plate 3 to lock the plug-in box 1 and the bus duct 2 with each other.

[0038] The plug-in box 1 is also provided with a clamping assembly, which is connected to the locking assembly. When the locking assembly is in operation, the clamping assembly clamps and fixes the first conductive copper bus 101 and the second conductive copper bus 201 that are misaligned.

[0039] In this solution, the bus duct 2 can drive the second conductive copper bus 201 to be misaligned and plugged into the second conductive copper bus 201 on the plug-in box 1, so that the Z-shaped clamping plate 3 and the locking assembly cooperate with each other, thereby locking the bus duct 2 and the plug-in box 1 with each other to avoid falling off. At the same time, the clamping assembly will clamp and fix the first conductive copper bus 101 and the second conductive copper bus 201 under the action of the locking assembly to improve the stability during connection.

[0040] In the present application, the connection and disconnection of the plug-in box 1 and the bus duct 2 are both relatively quick and do not require auxiliary tools, which improves the efficiency of assembly and disassembly while also making it more convenient for people to operate.

[0041] As a further solution of the utility model, the lock assembly includes a fixing plate 4 arranged on the plug-in box 1, a first slide groove 5 horizontally opened on the top of the fixing plate 4 along the length direction of the first conductive copper bar 101, and a first slide rod 6 with one end slidingly matched with the first slide groove 5;

[0042] A transverse plate 7 is horizontally disposed at the other end of the first sliding rod 6 , and the first sliding rod 6 is located in the gap of the first conductive copper bar 101 .

[0043] In this embodiment, during the process of the second conductive copper bar 201 being inserted into the first conductive copper bar 101 , the first conductive copper bar 101 will push the first slide bar 6 and the first slide groove 5 to slide relative to each other, and the first slide bar 6 will drive the cross plate 7 to move horizontally toward the plug-in box 1 .

[0044] As a further solution of the utility model, the lock assembly further includes a bracket 8 arranged on the plug-in box 1 and a key shaft 9 vertically slidingly matched with the bracket 8, and a roller 10 is rotatably arranged at one end of the key shaft 9, and the roller 10 is in contact with the top surface of the horizontal plate 7;

[0045] The outer wall of the key shaft 9 is provided with a baffle 11 , and the outer wall of the key shaft 9 is sleeved with a spring 12 , and two ends of the spring 12 are respectively against the baffle 11 and the bracket 8 .

[0046] In this embodiment, due to the presence of the spring 12 and the maintained compressed state, at the same time, the roller 10 is in contact with the top surface of the horizontal plate 7, so when the horizontal plate 7 is approaching the plug-in box 1 and finally separates from the roller 10, and the Z-shaped card plate 3 moves to the bottom of the roller 10 along with the bus duct 2, at this time, the key shaft 9 will drive the roller 10 to move downward to the top of the Z-shaped card plate 3 under the action of the spring 12;

[0047] Then continue to push the bus duct 2 toward the plug-in box 1, and the roller 10 will slide on the top surface of the Z-shaped card plate 3. When the roller 10 rolls to the right side of the Z-shaped card plate 3, it will continue to descend and interlock with the Z-shaped card plate 3, so that the bus duct 2 and the plug-in box 1 cannot be separated;

[0048] The key shaft 9 can only slide vertically with the bracket 8 but cannot rotate.

[0049] As a further solution of the utility model, the clamping assembly includes a cover plate 13 disposed on the plug-in box 1 and located on both sides of the first conductive copper bar 101, and a cross bar 14 horizontally slidingly matched with the cover plate 13;

[0050] A clamping plate 15 is disposed at one end of the cross bar 14 close to the first conductive copper bus 101 , and a first oblique block 16 is disposed at the other end of the cross bar 14 .

[0051] In this embodiment, when the first oblique block 16 drives the cross bar 14 to move toward the first conductive copper bar 101, the clamping plate 15 will move along with the cross bar 14, thereby clamping and fixing the first conductive copper bar 101 and the second conductive copper bar 201 which are mutually offset and plugged;

[0052] The cover plate 13 is used for horizontally slidingly supporting the cross bar 14 .

[0053] As a further solution of the utility model, the clamping assembly further comprises a fixing rod 17 horizontally arranged on the outer wall of the key shaft 9, a vertical rod 18 is vertically arranged on the bottom surface of the fixing rod 17, and a second oblique block 19 is arranged at the bottom end of the vertical rod 18;

[0054] The inclined surface of the second inclined block 19 fits with the inclined surface of the first inclined block 16 , and the first inclined block 16 will approach the first conductive copper bus 101 under the action of the second inclined block 19 .

[0055] In this embodiment, if Figure 5 As shown, since the inclined surface of the second oblique block 19 fits with the inclined surface of the first oblique block 16, during the vertical downward movement of the key shaft 9, the second oblique block 19 will be driven by the fixed rod 17 and the vertical rod 18 to push the first oblique block 16, so that the first oblique block 16 moves toward the position of the first conductive copper bus 101.

[0056] As a further solution of the utility model, a second slide rod 20 is vertically arranged at the bottom of the cross bar 14, and a second slide groove 21 which is perpendicular to the first slide groove 5 is horizontally opened on the top surface of the fixed plate 4, and the bottom end of the second slide rod 20 is located inside the second slide groove 21 and slides with each other.

[0057] In this embodiment, since the bottom end of the second slide bar 20 is located inside the second slide groove 21 and slides with each other, the stability of the cross bar 14 moving toward the first conductive copper bus 101 can be ensured when the first inclined block 16 is pushed by the second inclined block 19.

[0058] As a further solution of the utility model, a handle 22 is provided at the other end of the key shaft 9 , and the handle 22 can drive the roller 10 to separate from the Z-shaped clamping plate 3 through the key shaft 9 .

[0059] In this embodiment, the handle 22 can drive the key shaft 9 to overcome the elastic force of the spring 12 to move vertically. When the bus duct 2 and the plug-in box 1 need to be separated, the handle 22 is pulled vertically upward by external force. During this process, the handle 22 will drive the roller 10 to separate from the Z-shaped card plate 3 through the key shaft 9, so that the bus duct 2 and the plug-in box 1 can be separated.

[0060] In addition, since the spring 12 will be further compressed in the process of pulling the handle 22 upward, and the key shaft 9 will also drive the second oblique block 19 to move vertically upward by driving the fixing rod 17 and the vertical rod 18, the squeezing force of the second oblique block 19 on the first oblique block 16 is removed, that is, the first conductive copper bus 101 and the second conductive copper bus 201 will no longer be squeezed by the clamping plate 15.
