Description

Technical Field

[0001] This utility model relates to the technical field of busbars, and in particular to a sealing element for a busbar system. Background Technology

[0002] A busbar is made of highly conductive copper (copper busbar) or aluminum and is used to transmit electrical energy, serving the function of collecting and distributing power.

[0003] Busbars in existing electrical cabinets or other electrical locations are generally exposed. If personnel (including maintenance, repair, cleaning staff, or even unauthorized personnel who accidentally enter the area) inadvertently approach or touch the busbars, it can cause serious electric shock accidents. Therefore, designing a closed component that can cover the busbars to reduce electric shock accidents has become an urgent technical problem to be solved. Utility Model Content

[0004] In order to overcome the existing technical defects, the purpose of this utility model is to provide a closed element for busbar systems to solve the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] According to one aspect of this utility model, a sealing element for a busbar system is designed, comprising: a housing and end caps connected to both ends of the housing, both the housing and the end caps being made of insulating material. The lower part of the end cap is provided with an insertion notch for inserting a busbar. A connecting member made of insulating material is movably fitted at a slotted hole on the end cap. The connecting member includes a pressing part, a connecting part, a limiting part, and a snap-fit ​​part. The pressing part is arc-shaped and elastic. The left and right ends of the limiting part are correspondingly movably fitted into a first insertion groove and a second insertion groove on the end cap. A first limiting groove is provided at the left end of the limiting part. A first limiting block is provided in the first insertion groove, engaging with the first limiting groove. A snap-fit ​​part is provided with a snap-fit ​​position. When the pressing part is pressed down, the snap-fit ​​part moves downward; when the pressing part is pushed left or right, the snap-fit ​​part moves left or right. When the snap-fit ​​position is snapped tightly connected with the busbar, the first limiting groove engages with the first limiting block.

[0007] Using the above technical solution, when multiple busbars need to be covered, the cover is placed on the busbars, with both ends of the busbars placed in the insertion notches on the end caps. Then, the pressing part is pressed to change it from an arc shape to a straight shape. The connecting part, in conjunction with the limiting part and the locking part, moves downward. Then, pushing the pressing part to the left moves the locking part to the left, causing the locking position to move below the end of the busbar. Then, the pressing part is released, and the pressing part elastically resets, causing the limiting part and the locking part to move upward, so that the bottom surface of the locking position is locked onto the busbar. At the same time, the upper limit groove of the limiting part cooperates with the first limiting block to prevent the limiting part and the locking part from moving left and right. This allows the enclosure element of this solution to be installed on multiple busbars, covering the busbars and preventing them from being exposed. This prevents personnel (including maintenance, repair, cleaning personnel, and even unauthorized personnel) from touching the busbars, reducing the probability of electric shock accidents and improving safety.

[0008] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0009] In some embodiments, the left and right ends of the pressing portion abut against the end cap.

[0010] In some embodiments, a second limiting groove is provided at the right end of the limiting part, and a second limiting block that cooperates with the second limiting groove is provided in the second insertion groove.

[0011] In some embodiments, multiple first limiting grooves and second limiting grooves are arranged laterally, and one first limiting block and one first limiting block are respectively provided.

[0012] In some embodiments, the snap-fit ​​portion has two snap-fit ​​positions.

[0013] In some embodiments, the connecting part includes an upper connecting part and a lower connecting part, one of the upper connecting part and the lower connecting part is provided with a plug hole, and the other is provided with a plug post that is plugged into the plug hole. The upper connecting part is integrally formed with the pressing part, and the lower connecting part, the limiting part and the snap-fit ​​part are integrally formed.

[0014] In some embodiments, the end of the housing is inserted into a slot provided on the end cap.

[0015] In some embodiments, the housing includes a top cover and side covers located at the left and right ends of the top cover, wherein the ends of the side covers are inserted into insertion slots provided at the ends of the top cover. Attached Figure Description

The pressing part 31 is arc-shaped and elastic. The pressing part 31 is located on the top of the end cap 2, and its left and right ends abut against the end cap 2. The upper part of the connecting part 32 is placed in the strip hole 23 and can move left and right in the strip hole 23. The left and right ends of the limiting part 33 are movably fitted into the first insertion groove 24 and the second insertion groove 25 on the end cap 2. A snap-fit ​​part is provided on the left end of the limiting part 33. Alternatively, two or more first limiting grooves 331 may be arranged horizontally. Preferably, two or more first limiting grooves 331 are arranged horizontally on the left end of the limiting part 33, and one or two or more second limiting grooves 332 are arranged horizontally on the right end of the limiting part 33. A first limiting block 241 that cooperates with the first limiting groove 331 is provided in the first insertion groove 24, and a second limiting block 251 that cooperates with the second limiting groove 332 is provided in the second insertion groove 25. One first limiting block 241 and one first limiting block 241 are provided respectively. One, two or three locking positions 341 are provided on the locking part 34.

[0035] This enclosure element can be applied to standard straight busbars, T-type busbars, and I-type busbars. This embodiment describes how to connect and install it on a T-type busbar m. In the initial state, the connecting part 32 of the connector 3 is located at the right end of the strip-shaped through hole. When multiple busbars m need to be covered, the cover 1 is placed on the busbar m, and both ends of the busbar m are placed in the insertion notches 22 on the end caps 2. The locking part 34 is located on one side of one busbar m. Then, the pressing part 31 is pressed down to change it from an arc shape to a straight shape. The middle part of the pressing part 31 moves down in conjunction with the connecting part 32, the limiting part 33, and the locking part 34. Then, the pressing part 31 is pushed to the left to move the locking part 34 to the left, so that one of the locking positions 341 on the locking part 34 moves to below the right end of the busbar m. Then, the pressing part 31 is released. The middle part of the pressing part 31 elastically resets and moves upward in conjunction with the locking part 34, so that the bottom surface of the locking position 341 is locked onto the bottom right end of the bus m. At the same time, one of the first limiting grooves 331 on the limiting part 33 cooperates with the first limiting block 241 to prevent the limiting part 33 and the locking part 34 from moving left and right, thereby realizing the installation of the sealing element on multiple bus m. When it is necessary to remove the sealing element, press the pressing part 31 down again to make it change from an arc shape to a straight shape, so that the bottom surface of the locking position 341 is disengaged from the bus m. Then push the pressing part 31 to the right to move the locking part 34 to the left. After that, release the pressing part 31, and the middle part of the pressing part 31 elastically resets and moves upward. One of the second limiting grooves 332 on the limiting part 33 cooperates with the second limiting block 251 to keep the connector 3 in the initial position.

[0036] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
