Description

Technical Field

[0001] This utility model belongs to the field of power distribution equipment technology, and in particular relates to a sliding adjustable busbar structure. Background Technology

[0002] Busbars are conductive materials used in power systems, typically made of metals (such as copper or aluminum), primarily used to collect and distribute power to multiple output terminals. They play a crucial role in power supply systems, connecting the main switch in the electrical cabinet to switches in each branch circuit. Their surfaces are usually insulated, and their main function is as conductors. Currently, mounting holes are generally designed and machined on the busbars in advance. However, in actual use, due to the addition, removal, or repositioning of components, the pre-machined holes become unusable, rendering the busbars unsuitable for the actual component installation requirements. This necessitates re-machining the busbars, reducing installation efficiency and adding extra work. A busbar system with announcement number CN219458315U solves the problem of needing to re-drill holes in the busbar body by setting a sliding groove on the busbar body and connecting the slider to the sliding groove to allow electrical components to move relative to the busbar body. This structure requires the slider to be pre-installed inside the sliding groove according to the number of electrical components, or the slider can only slide in from one side of the sliding groove. However, in actual use, sometimes components are added in the middle of the busbar. When the slider is slid in from one side, it will be blocked by other sliders and cannot be directly installed in the middle position. Or, when it is necessary to adjust the installation position of a component, the slider corresponding to the component will be blocked by other sliders and cannot move. Therefore, in view of the above problems, it is particularly important to design a busbar structure with strong applicability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to improve the ease of installation of the sliding component relative to the busbar body by setting a sliding component between the branch body and the busbar body.

[0004] To solve the above-mentioned technical problems, this utility model provides a sliding adjustable busbar structure, including a busbar body and a branch busbar body connected to each other. The busbar body and the branch busbar body have copper strips for conducting electricity on their contact surfaces. A sliding component is provided between the branch busbar body and the busbar body. The busbar body has a groove for accommodating the sliding component. The groove includes a trapezoidal groove and a transition groove that are interconnected. The transition between the trapezoidal groove and the transition groove forms a stepped structure. The sliding component includes... The trapezoidal slider inside the trapezoidal groove can contact the stepped structure at the trapezoidal groove and the transition groove. The trapezoidal slider is provided with a connecting stud for fastening. The connecting stud passes through the support body and is threadedly connected to the trapezoidal slider. The upper end of the trapezoidal slider is provided with a telescopic sleeve. A limiting sleeve that can slide relative to its axial direction is fitted on the outer side of the telescopic sleeve. The telescopic sleeve can also rotate relative to the limiting sleeve. The upper end of the limiting sleeve is provided with a limiting block that can engage the busbar body.

[0005] This invention, by setting a sliding component between the busbar body and the branch body, restricts the width of the trapezoidal slider, allowing it to be conveniently and quickly placed inside the trapezoidal groove corresponding to the component's installation position. This facilitates the removal and insertion of the trapezoidal slider relative to the groove, improving the ease of installation. The telescopic sleeve allows for axial sliding relative to the limiting sleeve, providing axial adjustment. Even when the depth of the transition groove changes, it ensures contact between the trapezoidal slider and the stepped structure formed at the transition between the trapezoidal groove and the transition groove, expanding the applicability of the sliding component. Furthermore, the telescopic sleeve's ability to rotate relative to the limiting sleeve, combined with the limiting block that engages with the busbar body, improves the fixing efficiency of the trapezoidal slider.

[0006] Preferably, the transition groove extends from the outer side to the inner side of the busbar body, and the trapezoidal slide extends from the bottom of the transition groove to the inner side of the busbar body. The trapezoidal slide has a trapezoidal structure and the left and right width dimensions of the trapezoidal slide are greater than the width dimension of the transition groove.

[0007] Preferably, the length of the trapezoidal slider is greater than the width of the transition groove, and the width of the trapezoidal slider is less than the width of the transition groove.

[0008] Preferably, one end of the telescopic sleeve is fixedly connected to the trapezoidal slider, and the other end of the telescopic sleeve is disposed inside the limiting sleeve and can slide relative to its axial direction. The other end of the telescopic sleeve is also provided with a limiting ring, which is semi-circular and extends to the outside of the telescopic sleeve. The inner side of the limiting sleeve is provided with a limiting groove, which is three-quarters annular and extends outward from the inner side of the limiting sleeve and downward from the upper end of the limiting sleeve. The limiting ring is coaxially disposed inside the limiting groove and can rotate within a 90-degree range. The upper end of the limiting sleeve is fixedly connected to the limiting block, which has a through hole for the connecting stud to pass through. The limiting block is rectangular and can engage the busbar body.

[0009] Preferably, the busbar body has a locking groove that can restrict the rotation of the limiting block. The locking groove extends inward from the outside of the busbar body and passes through the transition groove. The left and right width of the locking groove is greater than the width of the transition groove. The limiting block is disposed inside the locking groove, and the height of the limiting block is less than the depth of the locking groove.

[0010] Preferably, the outer diameter of the limiting sleeve is smaller than the width of the transition groove; the height of the limiting sleeve is smaller than the depth of the transition groove; and the height of the telescopic sleeve is not greater than the height of the limiting sleeve.

Detailed Implementation

[0021] See attached document Figure 1 To the attached Figure 3 This utility model provides a sliding adjustable busbar structure, including a busbar body 201 and a branch busbar body 301 connected to each other. The branch busbar body 301 is used to mount components 101. The contact surfaces of both the busbar body 201 and the branch busbar body 301 are provided with conductive copper strips. A sliding component is provided between the branch busbar body 301 and the busbar body 201. The busbar body 201 has a groove for accommodating the sliding component. The sliding component can slide relative to the groove, realizing the function of sliding relative to the busbar body 201. The branch busbar body 301 is connected to the sliding component, thereby realizing the connection between the branch busbar body 301 and the busbar body 201. See also... Figure 3 The chute includes a trapezoidal chute 202 and a transition chute 203 that are interconnected. The transition chute 203 extends from the outside to the inside of the busbar body 201. The trapezoidal chute 202 extends from the bottom of the transition chute 203 to the inside of the busbar body 201. The trapezoidal chute 202 has a trapezoidal structure and its left and right width dimensions are greater than the width dimensions of the transition chute 203. The transition between the trapezoidal chute 202 and the transition chute 203 forms a stepped structure. That is, the upper end of the wider trapezoidal chute 202 and the lower end of the smaller transition chute 203 form a stepped structure due to the size difference.

[0022] See Figure 3 The sliding assembly includes a trapezoidal slider 204 disposed inside the trapezoidal groove 202. The trapezoidal slider 204 can contact the stepped structure at the trapezoidal groove 202 and the transition groove 203. The trapezoidal slider 204 has a certain length and width. The length dimension of the trapezoidal slider 204 is greater than the left and right width dimensions of the transition groove 203, and the width dimension of the trapezoidal slider 204 is less than the width dimension of the transition groove 203. When the length dimension of the trapezoidal slider 204 is placed inside the trapezoidal groove 202, it is its working position. This working position is used to fasten the busbar body 201 and the branch body 301. The trapezoidal slider 204 is provided with a connecting stud 211 for fastening. The connecting stud 211 can be a screw or a bolt. The connecting stud 211 passes through the branch body 301 and is threadedly connected to the trapezoidal slider 204.

[0023] With the above structure, when connecting the support column body 301 and the busbar body 201, the connecting stud 211 is first passed through the support column body 301. Then, a trapezoidal slider 204 is installed on the threaded end of the connecting stud 211, and the length direction of the trapezoidal slider 204 is adjusted to be parallel to the transition groove 203. Since the width of the trapezoidal slider 204 is smaller than the width of the transition groove 203, the trapezoidal slider 204 can pass through the transition groove 203 and be placed inside the trapezoidal slide groove 202. At this time, when the connecting stud 211 is rotated, the trapezoidal slider 204 will also rotate with the connecting stud 211. When the trapezoidal slider 204 rotates to the working position, that is, the length direction of the trapezoidal slider 204 is placed inside the trapezoidal slide groove 202, When the trapezoidal slider 204 can contact the inner wall of the trapezoidal groove 202, for example, by manually moving the connecting stud 211 up or down, the connecting stud 211 will move the trapezoidal slider 204 up and down inside the trapezoidal groove 202. When the trapezoidal slider 204 moves up and down, it can contact the upper or lower end of the trapezoidal groove 202. The trapezoidal slider 204 stops rotating and moves towards the support body 301 under the rotation of the connecting stud 211. The trapezoidal slider 204 is restricted at the stepped structure between the trapezoidal groove 202 and the transition groove 203. If the connecting stud 211 continues to rotate, the trapezoidal slider 204, the main body 201, and the support body 301 cannot move relative to each other, thus achieving the fixation of the support body 301 and the main body 201. Another installation method: The length direction of the trapezoidal slider 204 is parallel to the transition groove 203. The trapezoidal slider 204 is placed inside the trapezoidal groove 202 and in contact with the bottom of the groove. The trapezoidal slider 204 can be placed directly at the position where the component needs to be fixed according to the actual installation requirements. The connecting stud is passed through the support body 301 and then connected to the trapezoidal slider 204. Since the trapezoidal groove 202 is trapezoidal, the trapezoidal slider 204 will not rotate relative to the bottom of the trapezoidal groove 202. At this time, rotating the connecting stud can fix the support body 301 and the busbar body 201. By limiting the width of the trapezoidal slider 204 to be smaller than the width of the transition groove 203, the trapezoidal slider 204 can be taken out or put in at any position from the inside of the trapezoidal groove 202, which facilitates the installation of components.

[0024] See Figures 4 to 8Preferably, the upper end of the trapezoidal slider 204 is provided with a telescopic sleeve 207. A limiting sleeve 206, capable of sliding axially relative to the telescopic sleeve 207, is fitted onto the outer side of the telescopic sleeve 207. The telescopic sleeve 207 can also rotate relative to the limiting sleeve 206 within a certain angle range. The upper end of the limiting sleeve 206 is provided with a limiting block 205 capable of engaging the busbar body 201. One end of the telescopic sleeve 207 is fixedly connected to the trapezoidal slider 204, and the other end of the telescopic sleeve 207 is located inside the limiting sleeve 206 and can slide axially relative to it. The other end of the telescopic sleeve 207 is also provided with a limiting ring 208. (See also...) Figure 8 The limiting ring 208 is semi-circular and extends to the outside of the telescopic sleeve 207; see also Figure 7 The inner side of the limiting sleeve 206 is provided with a limiting groove 209, which is three-quarters annular in shape. The limiting groove 209 extends outward from the inner side of the limiting sleeve 206 and downward from the upper end of the limiting sleeve 206. The limiting ring 208 is coaxially disposed inside the limiting groove 209 and can rotate within a 90-degree range. When the limiting ring 208 rotates relative to the limiting groove 209, both ends B of the limiting ring 208 can contact both ends C of the limiting groove 209, thereby... The limiting groove 209 restricts the rotation range of the limiting ring 208; the limiting ring 208, in cooperation with the limiting groove 209, can limit the axial sliding range of the telescopic sleeve 207 relative to the limiting sleeve 206, and also limit its rotation within a 90-degree range; the upper end of the limiting sleeve 206 is fixedly connected to a limiting block 205, which has a through hole for the connecting stud 211 to pass through. The limiting block 205 is rectangular and can engage with the busbar body 201. See [reference needed] Figure 4 The busbar body 201 has a locking groove 210 that restricts the rotation of the limiting block 205. The locking groove 210 extends inward from the outside of the busbar body 201 and passes through the transition groove 203. The left and right width of the locking groove 210 is greater than the width of the transition groove 203. The limiting block 205 is located inside the locking groove 210, and the height of the limiting block 205 is less than the depth of the locking groove 210. Figure 4 In this design, the outer diameter of the limiting sleeve 206 is smaller than the width of the transition groove 203, allowing the limiting sleeve 206 to be placed inside the transition groove 203. The height of the limiting sleeve 206 is smaller than the depth of the transition groove 203, while the height of the telescopic sleeve 207 is not greater than the height of the limiting sleeve 206. With this design, when the telescopic sleeve 207 is fully retracted inside the limiting sleeve 206, the trapezoidal slider 204 can contact the upper end of the trapezoidal slide groove 202, thereby allowing the trapezoidal slider 204 to contact the busbar body 201, achieving a fixing function.

[0025] Through the above structure, the telescopic sleeve 207 can slide axially relative to the limiting sleeve 206. Simultaneously, under the action of the limiting ring 208 and the limiting groove 209, the telescopic sleeve 207 can rotate within a 90-degree range relative to the limiting sleeve 206. Since one end of the telescopic sleeve 207 is fixedly connected to the trapezoidal slider 204 and the upper end of the limiting sleeve 206 is fixedly connected to the limiting block 205, the trapezoidal slider 204 can move axially relative to the limiting block 205 and rotate within a 90-degree range. In use, the trapezoidal slider 204 is placed inside the trapezoidal groove 202. At this time, the limiting block 205 is located inside the locking groove 210 and locked, preventing relative rotation. The telescopic sleeve 207 is extended relative to the limiting sleeve 206, allowing the trapezoidal slider... 204 is away from the support body 301; the connecting stud 211 passes through the support body 301, then through the limiting block 205, the telescopic sleeve 207, and the limiting sleeve 206, and reaches the corresponding threaded hole of the trapezoidal slider 204 and is threadedly connected to it. When the connecting stud 211 is rotated, the connecting stud 211 drives the trapezoidal slider 204 to rotate. After the trapezoidal slider 204 rotates 90 degrees, it cannot continue to rotate. Therefore, when the connecting stud 211 is rotated, the trapezoidal slider 204 can move towards the support body 301 under the action of its threaded connection. As the trapezoidal slider 204 moves, the trapezoidal slider 204, the main body 201, and the support body 301 cannot move relative to each other, thus realizing the fixing function of the main body 201 and the support body 301. This structure allows the trapezoidal slider 204 to easily and quickly reach the working position, meaning the length of the trapezoidal slider 204 is located in the left-right direction of the trapezoidal groove 202, improving the installation efficiency of the trapezoidal slider 204; it also ensures that the trapezoidal slider 204 can fully contact the upper end of the trapezoidal groove 202, thereby increasing the reliability of the contact between the trapezoidal slider 204 and the busbar body 201; simultaneously, the telescopic sleeve 207 can slide axially relative to the limiting sleeve 206, allowing the telescopic sleeve 207 to be axially adjusted relative to the limiting sleeve 206, when the transition groove... Even when the depth of 203 changes, it can still ensure that the trapezoidal slider 204 contacts the step structure formed at the transition between the trapezoidal slide groove 202 and the transition groove 203, thus achieving the function of fixation. The telescopic sleeve 207 can rotate within a certain range relative to the limiting sleeve 206 and engage with the limiting block 205 that is engaged with the busbar body 201, thus limiting the range of rotation of the trapezoidal slider 204 inside the trapezoidal slide groove 202. This avoids the problem that the trapezoidal slider 204 cannot contact the inner wall of the trapezoidal slide groove 202 and continues to rotate with the connecting stud 211, thereby improving the efficiency of fixation.

[0026] This invention, by setting a sliding component between the busbar body and the branch body, limits the width of the trapezoidal slider, allowing it to be conveniently and quickly placed inside the trapezoidal groove corresponding to the component's installation position. This facilitates the removal and insertion of the trapezoidal slider relative to the groove, improving the ease of installation. The telescopic sleeve allows for axial sliding relative to the limiting sleeve, providing axial adjustment. Even when the depth of the transition groove changes, it ensures contact between the trapezoidal slider and the stepped structure formed at the transition between the trapezoidal groove and the transition groove, expanding the applicability of the sliding component. Furthermore, the telescopic sleeve allows for rotation within a certain range relative to the limiting sleeve, engaging with the limiting block that engages with the busbar body, improving the fixing efficiency of the trapezoidal slider.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
