Description

Technical Field

[0001] The present disclosure relates to the technical field of grounding wire clamps, and in particular to a grounding wire clamp for a rectangular busbar. Background Art

[0002] In the power industry, 400V power busbars mainly use a rectangular busbar structure (i.e., the conductor cross section is rectangular). Before maintenance, the busbar needs to be grounded using a 400V grounding wire to ensure the safety of personnel and equipment. During the grounding process, the grounding wire clamp connects the busbar to the grounding wire. One end of the grounding wire clamp is clamped on the busbar, and the other end is connected to the grounding wire to achieve the purpose of grounding the busbar.

[0003] The traditional grounding wire clamp is a jaw-type structure, and its shape and principle are similar to those of a clip. However, there are many problems with the traditional grounding wire clamp. For example, when the jaws are opened, the gripping part needs to be fully unfolded, which requires a larger operating space, making the grounding wire clamp unsuitable for use in a narrow working environment. When the jaws are opened, they form a V-shaped opening, which cannot match the rectangular structure of the busbar. Not only is the clamping force insufficient, making it prone to falling off, but the contact area is small, making it difficult to ensure safe grounding. Summary of the invention

[0025] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0026] like Figure 1 As shown, the embodiment of the present disclosure proposes a grounding wire clamp for a rectangular busbar 100, comprising: a first clamping metal 1, a second clamping metal 2 and a first elastic metal 3, the first clamping metal 1 is provided with a first clamping groove 14, and the first clamping metal 1 is used for grounding, the second clamping metal 2 is slidably arranged on the first clamping metal 1, and the second clamping metal 2 is provided with a second clamping groove 24, the second clamping groove 24 and the first clamping groove 14 are arranged opposite to each other, the first elastic metal 3 is arranged between the first clamping metal 1 and the second clamping metal 2, and the first elastic metal 3 is used to drive the first clamping metal 1 and the second clamping metal 2 to approach each other, so that the first clamping groove 14 and the second clamping groove 24 are respectively clamped at the two ends of the rectangular busbar 100.

[0027] It can be understood that since the second clamping metal 2 is slidably arranged on the first clamping metal 1, and the first elastic metal 3 is arranged between the first clamping metal 1 and the second clamping metal 2, the first clamping metal 1 and the second clamping metal 2 can move relative to each other under the elastic force of the first elastic metal 3 after moving away from each other, so that the first clamping groove 14 on the first clamping metal 1 and the second clamping groove 24 on the second clamping metal 2 can be respectively clamped at the two ends of the rectangular busbar 100, thereby realizing the clamping of the grounding wire clamp on the rectangular busbar 100. Therefore, when the first clamping metal 1 is grounded, the grounding of the rectangular busbar 100 can be achieved.

[0028] Among them, the clamping operation of the grounding wire clamp utilizes the back-to-back and relative movement of the first clamping metal 1 and the second clamping metal 2. The overall activity space is small, so it can be suitable for working environments with narrow space. At the same time, the clamping of the grounding wire clamp on the rectangular busbar 100 utilizes the first clamping groove 14 and the second clamping groove 24 respectively, and the first clamping groove 14 and the second clamping groove 24 can better match the rectangular structure of the busbar, thereby not only ensuring a larger clamping force and thus reducing the problem of falling off, but also ensuring a larger contact area and thus achieving safe grounding.

[0029] It should be noted that the rectangular busbar 100 is a busbar with a rectangular cross-sectional area, which can be applicable to a voltage level of 400V, and the grounding clamp is used for grounding during maintenance of the rectangular busbar 100.

[0030] The first clamping metal 1 is used to cooperate with the second clamping metal 2 to be clamped on the rectangular busbar 100. The specific type of the first clamping metal 1 can be set according to actual needs and is not limited to this. For example, the first clamping metal 1 can be U-shaped, and the U-shaped groove formed by the first clamping metal 1 is used as the first clamping groove 14 to be clamped at the end of the rectangular busbar 100 away from the second clamping metal 2. That is to say, the end of the rectangular busbar 100 away from the second clamping metal 2 passes through the first clamping groove 14 of the first clamping metal 1.

[0031] The second clamping metal 2 is used to cooperate with the first clamping metal 1 to be clamped on the rectangular busbar 100. The specific type of the second clamping metal 2 can be set according to actual needs and is not limited to this. For example, the second clamping metal 2 can be U-shaped, and the U-shaped groove formed by the second clamping metal 2 is used as the second clamping groove 24 to be clamped at the end of the rectangular busbar 100 away from the first clamping metal 1. That is to say, the end of the rectangular busbar 100 away from the first clamping metal 1 passes through the second clamping groove 24 of the second clamping metal 2.

[0032] The first elastic metal 3 is used for clamping the first clamping metal 1 and the second clamping metal 2 on the rectangular busbar 100. The specific type of the first elastic metal 3 can be set according to actual needs and is not limited to this. For example, the first elastic metal 3 can be a metal coil spring, one end of the first elastic metal 3 is connected to the first clamping metal 1, and the other end of the first elastic metal 3 is connected to the second clamping metal 2.

[0033] like Figure 1 As shown, in some embodiments, the first slot 14 includes: a first slot wall 141 and a second slot wall 142 in opposite positions, the rectangular busbar 100 includes: a first side surface 101 and a second side surface 102 in opposite positions, and the spacing between the first slot wall 141 and the second slot wall 142 is greater than the spacing between the first side surface 101 and the second side surface 102; the grounding wire clamp also includes: a second elastic metal 4, the second elastic metal 4 is arranged on the first slot wall 141, and the second elastic metal 4 is used to abut against the first side surface 101 to make the second side surface 102 and the second slot wall 142 fit.

[0034] It can be understood that, since the spacing between the first slot wall 141 and the second slot wall 142 is greater than the spacing between the first side surface 101 and the second side surface 102, the first slot 14 with a larger width can be easily clamped on the rectangular busbar 100 with a smaller width. At the same time, since the second elastic metal 4 is arranged on the first slot wall 141, the second side surface 102 of the rectangular busbar 100 and the second slot wall 142 of the first slot 14 can be tightly fitted by utilizing the elastic force of the second elastic metal 4, thereby ensuring the stable clamping of the first slot 14 on the rectangular busbar 100 and the effective contact between the first clamping metal 1 and the rectangular busbar 100.

[0035] Therefore, the grounding wire clamp can be efficiently disassembled and assembled on the rectangular busbar 100, which can not only ensure a greater clamping force to reduce the problem of falling off, but also ensure a larger contact area to achieve safe grounding.

[0036] It should be noted that the first slot 14 is used to be clamped at one end of the rectangular busbar 100 away from the second clamping metal 2, and the first slot wall 141 and the second slot wall 142 of the first slot 14 are used to match the first side surface 101 and the second side surface 102 of the rectangular busbar 100. The specific types of the first slot wall 141 and the second slot wall 142 can be set according to actual needs and are not limited to this. For example, the second slot wall 142 is a planar structure to effectively fit the second side surface 102 of the rectangular busbar 100, and the length of the second slot wall 142 is greater than the length of the first slot wall 141 to achieve a large-area contact between the rectangular busbar 100 and the first clamping metal 1.

[0037] The second elastic metal 4 is used to apply elastic force on the rectangular busbar 100 to ensure that the second side surface 102 and the second slot wall 142 are stably fitted. The specific type of the second elastic metal 4 can be set according to actual needs and is not limited to this. For example, the second elastic metal 4 can be a curved spring sheet.

[0038] In some embodiments, the second elastic metal 4 is obliquely disposed on the first slot wall 141 , and the distance between the second elastic metal 4 and the first slot wall 141 increases linearly along the direction from the slot opening to the slot bottom of the first slot 14 .

[0039] It can be understood that since the distance between the second elastic metal 4 and the first slot wall 141 increases linearly in the direction from the slot opening to the slot bottom of the first slot 14, the end of the rectangular busbar 100 away from the second clamping metal 2 can be smoothly inserted from the slot opening of the first slot 14 to avoid jamming, thereby effectively improving the installation efficiency of the grounding clamp. At the same time, by utilizing the inclined structure of the second elastic metal 4, the stable clamping of the first slot 14 on the rectangular busbar 100 and the effective contact between the first clamping metal 1 and the rectangular busbar 100 can be achieved.

[0040] It should be noted that the specific arrangement of the second elastic metal 4 can be set according to actual needs, and there is no limitation to this. For example, the direction of the second elastic metal 4 can be parabolic.

[0041] like Figure 1As shown, in some embodiments, the first clamping metal 1 includes: a first part 11, a second part 12 and a third part 13, the first part 11 and the second clamping metal 2 are arranged oppositely, the second part 12 is arranged at one end of the first part 11, the third part 13 is arranged at one end of the first part 11 away from the second part 12, and the second clamping metal 2 is slidably arranged at one end of the third part 13 away from the first part 11, the first elastic metal 3 is arranged between the third part 13 and the second clamping metal 2, and the third part 13 is used for grounding. Among them, the second part 12 and the third part 13 are arranged oppositely, and the side of the second part 12 close to the third part 13 is used as the first groove wall 141, and the side of the third part 13 close to the second part 12 is used as the second groove wall 142.

[0042] It can be understood that since the first part 11 and the second clamping metal 2 are arranged relative to each other, and the second part 12 is arranged at one end of the first part 11, and the third part 13 is arranged at the end of the first part 11 away from the second part 12, the first part 11, the second part 12 and the third part 13 constitute a first clamping metal 1 of a U-shaped structure, so that the side of the second part 12 close to the third part 13 can better match the first side 101 of the rectangular busbar 100, and the side of the third part 13 close to the second part 12 can better match the second side 102 of the rectangular busbar 100, thereby not only ensuring a larger clamping force of the grounding wire clamp and reducing the problem of falling off, but also ensuring a larger contact area of ​​the grounding wire clamp to achieve safe grounding.

[0043] It should be noted that the first part 11, the second part 12 and the third part 13 are used to constitute the U-shaped first clamping metal 1. The specific types of the first part 11, the second part 12 and the third part 13 can be set according to actual needs and are not limited to this. For example, the first part 11, the second part 12 and the third part 13 are respectively plate structures, and the length of the third part 13 is greater than the length of the second part 12.

[0044] like Figure 1 As shown, in some embodiments, the second slot 24 includes: a third slot wall 241 and a fourth slot wall 242 in opposite positions, the rectangular busbar 100 includes: a first side surface 101 and a second side surface 102 in opposite positions, and the distance between the third slot wall 241 and the fourth slot wall 242 is greater than the distance between the first side surface 101 and the second side surface 102. The grounding clamp also includes: a third elastic metal 5, which is arranged on the third slot wall 241, and the third elastic metal 5 is used to abut against the first side surface 101, so that the second side surface 102 and the fourth slot wall 242 fit.

[0045] It can be understood that, since the spacing between the third slot wall 241 and the fourth slot wall 242 is greater than the spacing between the first side surface 101 and the second side surface 102, the second slot 24 with a larger width can be easily clamped on the rectangular busbar 100 with a smaller width. At the same time, since the third elastic metal 5 is arranged on the third slot wall 241, the second side surface 102 of the rectangular busbar 100 and the fourth slot wall 242 of the second slot 24 can be tightly fitted by utilizing the elastic force of the third elastic metal 5, thereby ensuring the stable clamping of the second slot 24 on the rectangular busbar 100 and the effective contact between the second clamping metal 2 and the rectangular busbar 100.

[0046] Therefore, the grounding wire clamp can be efficiently disassembled and assembled on the rectangular busbar 100, which can not only ensure a greater clamping force to reduce the problem of falling off, but also ensure a larger contact area to achieve safe grounding.

[0047] It should be noted that the second slot 24 is used to be clamped at one end of the rectangular busbar 100 away from the first clamping metal 1, and the third slot wall 241 and the fourth slot wall 242 of the second slot 24 are used to match the first side surface 101 and the second side surface 102 of the rectangular busbar 100. The specific types of the third slot wall 241 and the fourth slot wall 242 can be set according to actual needs and are not limited to this. For example, the fourth slot wall 242 is a planar structure to effectively fit the second side surface 102 of the rectangular busbar 100, and the length of the fourth slot wall 242 is greater than the length of the third slot wall 241 to achieve large-area contact between the rectangular busbar 100 and the second clamping metal 2.

[0048] The third elastic metal 5 is used to apply elastic force on the rectangular busbar 100 to ensure that the second side surface 102 and the fourth slot wall 242 are stably fitted. The specific type of the third elastic metal 5 can be set according to actual needs and is not limited to this. For example, the third elastic metal 5 can be a curved spring sheet.

[0049] In some embodiments, the third elastic metal 5 is obliquely disposed on the third slot wall 241 , and the distance between the third elastic metal 5 and the third slot wall 241 increases linearly along the direction from the slot opening to the slot bottom of the second slot 24 .

[0050] It can be understood that since the distance between the third elastic metal 5 and the third slot wall 241 increases linearly in the direction from the slot opening to the slot bottom of the second slot 24, the end of the rectangular busbar 100 away from the first clamping metal 1 can be smoothly inserted into the slot opening of the second slot 24 to avoid jamming, thereby effectively improving the installation efficiency of the grounding clamp. At the same time, by utilizing the inclined structure of the third elastic metal 5, the second slot 24 can be stably clamped on the rectangular busbar 100 and the second clamping metal 2 and the rectangular busbar 100 can be effectively contacted.

[0051] It should be noted that the specific arrangement of the third elastic metal 5 can be set according to actual needs, and there is no limitation to this. For example, the direction of the third elastic metal 5 can be parabolic.

[0052] like Figure 1 As shown, in some embodiments, the second clamping metal 2 includes: a fourth portion 21, a fifth portion 22 and a sixth portion 23, the fourth portion 21 and the first clamping metal 1 are arranged oppositely, the fifth portion 22 is arranged at one end of the fourth portion 21, the sixth portion 23 is arranged at one end of the fourth portion 21 away from the fifth portion 22, and the sixth portion 23 is slidably arranged on the first clamping metal 1, and the first elastic metal 3 is arranged between the sixth portion 23 and the first clamping metal 1. Among them, the fifth portion 22 and the sixth portion 23 are arranged oppositely, and the side of the fifth portion 22 close to the sixth portion 23 serves as the third groove wall 241, and the side of the sixth portion 23 close to the fifth portion 22 serves as the fourth groove wall 242.

[0053] It can be understood that since the fourth part 21 and the first clamping metal 1 are arranged relative to each other, and the fifth part 22 is arranged at one end of the fourth part 21, and the sixth part 23 is arranged at the end of the fourth part 21 away from the fifth part 22, the fourth part 21, the fifth part 22 and the sixth part 23 constitute the second clamping metal 2 of the U-shaped structure, so that the side of the fifth part 22 close to the sixth part 23 can better match the first side 101 of the rectangular busbar 100, and the side of the sixth part 23 close to the fifth part 22 can better match the second side 102 of the rectangular busbar 100, thereby not only ensuring a larger clamping force of the grounding wire clamp and reducing the problem of falling off, but also ensuring a larger contact area of ​​the grounding wire clamp to achieve safe grounding.

[0054] It should be noted that the fourth part 21, the fifth part 22 and the sixth part 23 are used to constitute the U-shaped second clamping metal 2. The specific types of the fourth part 21, the fifth part 22 and the sixth part 23 can be set according to actual needs and are not limited to this. For example, the fourth part 21, the fifth part 22 and the sixth part 23 are respectively plate structures, and the length of the sixth part 23 is greater than the length of the fifth part 22.

[0055] like Figure 1 As shown, in some embodiments, the first clamping metal 1 is provided with a slide groove 15, and the first elastic metal 3 is arranged in the slide groove 15, and the second clamping metal 2 is provided with a slider 25, and the slider 25 is slidably arranged in the slide groove 15 and connected to the first elastic metal 3.

[0056] It can be understood that since the slider 25 of the second clamping metal 2 is slidably set in the slide groove 15 of the first clamping metal 1, and the first elastic metal 3 is set in the slide groove 15 and connected to the slider 25, the first clamping metal 1 and the second clamping metal 2 can move relative to each other under the elastic force of the first elastic metal 3 after moving back to back, so that the first clamping groove 14 on the first clamping metal 1 and the second clamping groove 24 on the second clamping metal 2 can be respectively clamped at the two ends of the rectangular bus 100, thereby realizing the stable clamping of the grounding wire clamp on the rectangular bus 100, ensuring the stable grounding of the rectangular bus 100.

[0057] It should be noted that the slide groove 15 is used to cooperate with the slider 25 to realize the sliding setting of the second clamping metal 2 on the first clamping metal 1. The specific type of the slide groove 15 can be set according to actual needs and is not limited to this. For example, the slide groove 15 is set at one end of the third part 13 close to the sixth part 23, and the inner wall of the slide groove 15 fits the outer wall of the slider 25.

[0058] The slider 25 is used to cooperate with the slide groove 15 to realize the sliding setting of the second clamping metal 2 on the first clamping metal 1. The specific type of the slider 25 can be set according to actual needs and is not limited to this. For example, the slider 25 is set at one end of the sixth part 23 close to the third part 13, and the outer wall of the slider 25 fits the inner wall of the slide groove 15.

[0059] like Figure 1 As shown, in some embodiments, the grounding clamp further includes: an insulating operating rod 6 , and the insulating operating rod 6 is arranged on the second clamping metal 2 .

[0060] It can be understood that since the insulating operating rod 6 is arranged on the second clamping metal 2, the operator can hold the insulating operating rod 6 to achieve the opposite movement of the second clamping metal 2 and the first clamping metal 1, thereby facilitating the first clamping groove 14 and the second clamping groove 24 to be respectively clamped at the two ends of the rectangular busbar 100, thereby ensuring the stable grounding of the rectangular busbar 100.

[0061] It should be noted that the insulating operating rod 6 is made of insulating material, and the specific type of the insulating operating rod 6 can be set according to actual needs, without limitation. For example, the insulating operating rod 6 is arranged on the fourth part 21, and the axial direction of the insulating operating rod 6 is parallel to the sliding direction of the second clamping metal 2.

[0062] During use, the operator can use the insulating operating rod 6 to hook the first clamping groove 14 of the grounding wire clamp obliquely on one end of the rectangular busbar 100, and then apply force to move the first clamping metal 1 and the second clamping metal 2 away from each other. When the opening size between the first clamping metal 1 and the second clamping metal 2 is larger than the size of the rectangular busbar 100, the second clamping groove 24 is clamped at the other end of the rectangular busbar 100, so as to use the first elastic metal 3 to clamp the first clamping metal 1 and the second clamping metal 2 on the rectangular busbar 100, and under the action of the second elastic metal 4 and the third elastic metal 5, the grounding wire clamp can be stably clamped on the rectangular busbar 100, while ensuring effective contact between the grounding wire clamp and the rectangular busbar 100.

[0063] like Figure 1 As shown, in some embodiments, the grounding wire clamp further includes: a metal block 7 and a metal wire 8, the metal block 7 is disposed on the first clamping metal 1, one end of the metal wire 8 is connected to the metal block 7, and the end of the metal wire 8 away from the metal block 7 is used for grounding.

[0064] It can be understood that since the metal block 7 is arranged on the first clamping metal 1 and one end of the metal wire 8 is connected to the metal block 7, when the end of the metal wire 8 away from the metal block 7 is grounded, the metal block 7 can be used to achieve the grounding of the first clamping metal 1, and then the grounding of the rectangular busbar 100 is achieved.

[0065] It should be noted that the metal block 7 is used for grounding the first clamping metal 1. The specific type of the metal block 7 can be set according to actual needs and is not limited to this. For example, the metal block 7 can be a block of metal. The metal block 7 can be set on the third part 13 by welding, bolting, etc., or the metal block 7 can also be set on the third part 13 by magnetic attraction, snap-on fixing, etc.

[0066] The metal wire 8 is used for grounding the first clamping metal 1 . The specific type of the metal wire 8 can be set according to actual needs and is not limited thereto.

[0067] When hanging the ground wire on the busbar in a 400V distribution cabinet, the traditional jaw-type wire clamp is replaced with the ground wire clamp of this embodiment.
