Description

Technical Field

[0001] The utility model relates to the technical field of plug-in boxes, in particular to a busbar plug-in box with anti-loosening function. Background Technique

[0002] The main function of the busbar plug-in box is to extend and expand the branch circuit of the busbar. The circuit is disconnected and protected through the circuit breaker in the plug-in box, so as to shunt the current of the main line of the busbar to the electrical equipment.

[0003] The busbar plug-in box is a common feeder method in the busbar system, generally composed of a box body, an air switch and a plug-in part. Its function is to distribute the current of the busbar to various electrical equipment, which 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 whole line. If the electrical equipment is increased later, the original plug-in box can be directly unplugged and replaced with a plug-in box with a larger current. This design enables the busbar system to flexibly adapt to different power demands while ensuring safety and reliability.

[0004] The connection method between the busbar and the plug-in box is mainly to fix the conductor of the plug-in box and the conductor of the busbar through fastening bolts. Not only tools are needed for installation and connection, but also the disassembly and installation operations are rather troublesome. And after using for a period of time, it may become loose or corroded due to various uncertain factors, such as humidity, vibration, etc. Becoming loose will affect the transmission of the circuit and may also pose a safety hazard, and becoming corroded will increase the difficulty of disassembly and repair.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0045] Please refer to Figures 1-9 , in the embodiments of the present utility model, an anti - loosening busbar trunking plug - in box includes a box body 1, the box body 1 is detachably connected to a busbar trunking 2, a first conductive copper bar 101 is provided on the box body 1, and a second conductive copper bar 201 is provided on the busbar trunking 2;

[0046] On both sides of the first conductive copper bar 101 on the box body 1, there are first cover plates 3 arranged. On both sides of the second conductive copper bar 201 on the busbar chute 2, there are second cover plates 4 arranged. Through holes corresponding to each other, namely first limiting holes 301 and second limiting holes 401, are respectively formed through the first cover plates 3 and the second cover plates 4;

[0047] On the box body 1, there is an anti - detachment limiting mechanism arranged. On the second cover plate 4, there is a push rod 5 which can cooperate with the anti - detachment limiting mechanism. During the connection process of the busbar chute 2 and the box body 1, the anti - detachment limiting mechanism will respectively penetrate through the first limiting hole 301 and the second limiting hole 401 under the action of the push rod 5, so that the first cover plate 3 and the second cover plate 4 are locked to each other;

[0048] On the box body 1, there is also a clamping assembly arranged. The clamping assembly is connected to the anti - detachment limiting mechanism. When the anti - detachment limiting mechanism operates past the critical position, the clamping assembly will cooperate with the anti - detachment limiting mechanism to clamp and fix the misaligned and inserted first conductive copper bar 101 and second conductive copper bar 201.

[0049] In this solution, during the insertion process of the busbar chute 2 and the box body 1, through the cooperation between the push rod 5 and the anti - detachment limiting mechanism, the first limiting hole 301 and the second limiting hole 401 are successively penetrated by the anti - detachment limiting mechanism, so that the first cover plate 3 and the second cover plate 4 are locked to each other. When the anti - detachment limiting mechanism exceeds the critical position under the action of the push rod 5, the clamping assembly will cooperate with the anti - detachment limiting mechanism to clamp and fix the misaligned and inserted first conductive copper bar 101 and second conductive copper bar 201;

[0050] In this application, during the insertion process of the busbar chute 2 and the box body 1, by using the mutual cooperation among the arranged push rod 5, anti - detachment limiting mechanism and clamping assembly, the busbar chute 2 and the box body 1 are automatically locked, and the misaligned and inserted first conductive copper bar 101 and second conductive copper bar 201 can also be clamped and fixed; compared with the traditional connection method, it can not only ensure the stability during connection, avoid the probability of loosening, but also does not require the assistance of tools for connection. At the same time, the operation is relatively convenient and the connection efficiency is improved.

[0051] As a further solution of the present utility model, the anti - detachment limiting mechanism includes a slide rail 6 arranged on the box body 1 along the length direction of the first conductive copper bar 101 and a slide plate 7 which is slidably matched with the slide rail 6;

[0052] The position of the slide plate 7 corresponds to that of the push rod 5. On the side of the slide plate 7 away from the push rod 5, there is a push post 8 arranged.

[0053] In this embodiment, during the insertion process of the busbar trunking 2 into the box body 1, the first conductive copper bar 101 and the second conductive copper bar 201 will be inserted in a mutually offset manner, the second cover plate 4 will be connected to the first cover plate 3 in a misaligned manner, and the push rod 5 will touch the sliding plate 7 and push the sliding plate 7 closer to the box body 1;

[0054] During the process of the sliding plate 7 approaching the box body 1, the sliding plate 7 drives the push column 8 to push the rotating plate 11 while slidingly cooperating with the slide rail 6.

[0055] As a further solution of the present utility model, a bracket 9 is provided on the box body 1, a worm 10 is vertically rotatably arranged on the bracket 9, a rotating plate 11 is arranged on the outer wall of the worm 10, and one side of the rotating plate 11 is in contact with the end of the push column 8.

[0056] In this embodiment, since the rotating plate 11 is arranged on the outer wall of the worm 10 and the worm 10 is vertically rotatably arranged on the bracket 9, when the push column 8 pushes the rotating plate 11, the rotating plate 11 will drive the worm 10 to rotate together.

[0057] As a further solution of the present utility model, a fixing frame 12 is provided on the box body 1, a bidirectional lead screw 13 is horizontally rotatably arranged on the fixing frame 12, and the length direction of the bidirectional lead screw 13 is perpendicular to the length direction of the first conductive copper bar 101;

[0058] A worm gear 14 is arranged on the outer wall of the bidirectional lead screw 13, and the worm gear 14 meshes with the worm 10.

[0059] In this embodiment, since the worm gear 14 meshes with the worm 10, when the worm 10 rotates, it will drive the worm gear 14 to rotate. Also, because the worm gear 14 is fixed on the outer wall of the bidirectional lead screw 13 and the bidirectional lead screw 13 is horizontally rotatably arranged on the fixing frame 12, the bidirectional lead screw 13 will rotate following the worm gear 14.

[0060] As a further solution of the present utility model, a guide rod 15 is arranged on the box body 1 parallel to the length direction of the bidirectional lead screw 13, and an L-shaped rod 16 is slidably fitted on the outer wall of the guide rod 15;

[0061] One end of the L-shaped rod 16 is threadedly connected to the bidirectional lead screw 13, and a limiting rod 17 is arranged at the other end of the L-shaped rod 16, and the position of the limiting rod 17 corresponds to the position of the first limiting hole 301.

[0062] In this embodiment, as Figure 6 shown, since one end of the L-shaped rod 16 is threadedly connected to the bidirectional lead screw 13 and the L-shaped rod 16 is slidably fitted with the guide rod 15, when the bidirectional lead screw 13 rotates, the L-shaped rod 16 will move the first cover plate 3 closer.

[0063] Moreover, since a limiting rod 17 corresponding to the position of the first limiting hole 301 is provided at the other end of the L-shaped rod 16, the limiting rod 17 will move along with the L-shaped rod 16 and insert into the first limiting hole 301. At this time, the first limiting hole 301 and the second limiting hole 401 are exactly aligned, so the limiting rod 17 will be inserted into the first limiting hole 301 and the second limiting hole 401 respectively.

[0064] As a further solution of the present invention, the clamping assembly includes a sleeve 18 and a sliding rod 19 slidably engaged with the sleeve 18. One end of the sleeve 18 is horizontally rotatably connected to the outer wall of the box body 1, and one end of the sliding rod 19 is rotatably connected to the bottom surface of the rotating plate 11;

[0065] A baffle 20 is provided at the other end of the sliding rod 19, and a spring 21 is provided inside the sleeve 18. The spring 21 is sleeved outside the sliding rod 19 and its two ends are respectively abutted against the inner wall of the other end of the sleeve 18 and the side wall of the baffle 20.

[0066] In this embodiment, due to the presence of the spring 21, the rotating plate 11 is always in close contact with the push post 8. Moreover, since one end of the sliding rod 19 is rotatably connected to the bottom surface of the rotating plate 11, when the rotating plate 11 rotates under the action of the push post 8, the sliding rod 19 will drive the sleeve 18 to rotate together with the rotating plate 11 and gradually slide out of the sleeve 18. During this process, the baffle 20 will squeeze the spring 21 along with the sliding rod 19.

[0067] As a further solution of the present invention, the plane formed by the central axes of one end of the sleeve 18 and the worm 10 is parallel to the length direction of the bidirectional lead screw 13;

[0068] An obtuse angle is formed between the rotating plate 11 and the push post 8, and an acute angle is formed between the rotating plate 11 and the sliding rod 19.

[0069] In this embodiment, when the rotating plate 11 rotates to form a 90-degree angle with the push post 8 under the push of the push post 8, at this time, the central axes of the rotating plate 11, the sleeve 18 and the sliding rod 19 will be in the same plane, and the spring 21 is squeezed to the maximum state. In addition, the first limiting hole 301 and the second limiting hole 401 are exactly aligned, and the limiting rod 17 is inserted into the first limiting hole 301 and the second limiting hole 401 respectively;

[0070] In the above state, the busbar 2 drives the push rod 5 to move a certain distance towards the box body 1, and the push rod 5 will cause the rotating plate 11 to rotate past the critical point, and the spring 21 will quickly contract, thereby driving the rotating plate 11 to rotate rapidly counterclockwise. At the same time, the limiting rod 17 will move further quickly towards the first conductive copper bar 101 under the combined action of the worm 10, the worm gear 14, the bidirectional lead screw 13, the guide rod 15 and the L-shaped rod 16.

[0071] As a further solution of the present invention, a T-shaped sliding groove 22 is horizontally opened on the outer wall of the box body 1 close to the first conductive copper bar 101, and a clamping plate 23 is slidably fitted in the T-shaped sliding groove 22.

[0072] In this embodiment, due to the existence of the clamping plate 23 and its sliding fit with the T-shaped sliding groove 22, during the process of the limiting rod 17 moving quickly towards the first conductive copper bar 101, it will touch the clamping plate 23 and push the clamping plate 23 to clamp the misaligned and inserted first conductive copper bar 101 and the second conductive copper bar 201.

[0073] As a further solution of the present invention, the distance between the two first covers 3 is greater than the distance between the two second covers 4, and the distance between the two clamping plates 23 is less than the distance between the two second covers 4.

[0074] In this embodiment, since the distance between the two first covers 3 is greater than the distance between the two second covers 4, during the process of the busbar 2 being inserted into the box body 1, the two second covers 4 can also be connected in a dislocation manner with the two first covers 3, and the first limiting holes 301 and the second limiting holes 401 can also be aligned with each other;

[0075] Also, because the distance between the two clamping plates 23 is less than the distance between the two second covers 4, therefore, during the process of the limiting rod 17 moving quickly towards the first conductive copper bar 101, it will first touch the clamping plate 23, thereby driving the clamping plate 23 to clamp the first conductive copper bar 101.
