Description

Technical Field

[0001] The present application relates to the technical field of tooling and fixture development, and in particular to a copper busbar clamping device. Background Art

[0002] Copper busbars, as electrical connectors, are widely used in power cabinets, primarily for transmitting current and connecting devices. They are primarily made from long copper bars with rectangular or chamfered rectangular cross-sections, processed through cutting, bending, punching, riveting, and surface treatment. With the increasing diversification and complexity of product industrial design, copper busbars require a variety of shapes. They are primarily distributed horizontally and vertically within electrical equipment to achieve a more compact and regular overall structure.

[0003] During structural design, holes are typically drilled at the overlap locations of the horizontal and vertical copper bars, and fasteners apply a high torque to lock the overlapping copper bars together to complete assembly. Due to the high torque required to lock the overlapping copper bars, problems such as insufficient copper bar contact surface, increased contact resistance, severe resistance heat generation, and low energy conversion can occur. There is even a risk of the copper bars melting due to unreliable connections. Copper bar overlap types are categorized as linear or vertical based on the assembly direction. A linear connection refers to overlapping copper bars in the same direction, while a vertical connection refers to overlapping copper bars at right angles to each other.

[0004] Currently, copper busbar overlaps are primarily tightened manually during production and assembly. However, when the required torque is high, the copper busbars can easily slip during tightening, causing the overlap position to shift and affecting assembly. Consequently, the fasteners must be repeatedly loosened and tightened to achieve the required overlap. However, this method suffers from low installation efficiency, copper busbar assembly errors, high labor intensity, and high labor costs. An effective mounting and clamping device is particularly needed for vertically connected copper busbar overlaps. Utility Model Content

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0044] As mentioned in the background technology, existing copper busbar overlap locking is mainly performed manually. When the required torque is large, the copper busbar is prone to rotational slippage during the continuous tightening process of the fastener, resulting in a shift in the overlap position, affecting assembly and installation. To this end, the inventors of this application have designed a new copper busbar clamping device. This copper busbar clamping device can solve the problem of the copper busbar being prone to rotational slippage and resulting in a shift in the overlap position during the overlap locking process of vertically connected copper buses in the prior art. The copper busbar clamping device of this application will be described in detail below with reference to the accompanying drawings.

[0045] It should be noted that the “first direction” in this application refers to the Figure 1 The direction indicated by the letter X in the figure is the direction indicated by the letter X in the figure. The second direction is the direction indicated by the letter X in the figure. Figure 1 The direction indicated by the letter Y.

[0046] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a copper busbar clamping device is provided, which includes a base 10 and a locking mechanism 20 .

[0047] The base 10 is provided with a first bearing portion 101, a second bearing portion 102 and an avoidance portion 103. The first bearing portion 101 extends along a first direction to at least support the first copper busbar 30, and the second bearing portion 102 extends along a second direction to at least support the second copper busbar 40. The first direction is perpendicular to the second direction. The avoidance portion 103 is at least used to avoid the locking member 60 used to lock the first copper busbar 30 and the second copper busbar 40. The locking mechanism 20 is provided on the base 10 to at least lock the first copper busbar 30 to the first bearing portion 101 and lock the second copper busbar 40 to the second bearing portion 102.

[0048] In this embodiment, when the copper bar clamping device is actually used, the first copper bar 30 and the second copper bar 40 can be placed on the first load-bearing portion 101 and the second load-bearing portion 102 respectively, so that the first copper bar 30 and the second copper bar 40 are overlapped together, and the overlapping position of the two is located at the avoidance portion 103 of the base 10. When it is necessary to lock the first copper bar 30 and the second copper bar 40, it is only necessary to control the locking mechanism 20 to lock the first copper bar 30 on the first load-bearing portion 101 and the second copper bar 40 on the second load-bearing portion 102, and then insert the locking member 60 into the overlapping position of the first copper bar 30 and the second copper bar 40, and then apply a torsional force to the locking member 60 to achieve the overlapping locking of the first copper bar 30 and the second copper bar 40. During this process, the presence of the locking mechanism 20 can lock the first copper busbar 30 and the second copper busbar 40 on the first load-bearing part 101 and the second load-bearing part 102 respectively, thereby preventing the first copper busbar 30 and the second copper busbar 40 from rotating and slipping during the locking process of the locking piece 60, thereby preventing the overlapping position from being offset. In addition, the entire overlapping locking process does not require repeated adjustment of the copper busbar position, which effectively improves the installation efficiency of the copper busbar overlap and reduces labor intensity and labor costs.

[0049] Specifically, the "avoidance portion 103" in this embodiment includes an avoidance hole, which is provided to provide a rotation space for the locking member 60, so that the locking member 60 can be inserted into the overlapping position of the first copper bar 30 and the second copper bar 40, so as to lock the first copper bar 30 and the second copper bar 40 under the action of an external force. Exemplarily, in this embodiment, the first copper bar 30 and the second copper bar 40 are locked and connected by a locking member 60 such as a bolt or a stud.

[0050] Further, see Figure 1 as well as Figure 3 As shown, the locking mechanism 20 in this embodiment includes a first stopper 21, a second stopper 22, a first sliding assembly 23, and a second sliding assembly 24. The first stopper 21 is protruding from the side of the first bearing portion 101; the second stopper 22 is protruding from the side of the second bearing portion 102; the first sliding assembly 23 reciprocates along the second direction and cooperates with the first stopper 21 to lock the first copper bar 30 to the first bearing portion 101; the second sliding assembly 24 reciprocates along the first direction and cooperates with the second stopper 22 to lock the second copper bar 40 to the second bearing portion 102. In this way, the first copper bar 30 and the second copper bar 40 can be prevented from rotating and slipping during the locking process of the locking member 60, thereby preventing the overlap position from shifting, effectively improving the installation efficiency of the copper bar overlap and reducing labor intensity and labor costs.

[0051] Specifically, in this embodiment, the first copper bar 30 can be locked on the first bearing portion 101 under the cooperation of the first stop portion 21 and the first sliding assembly 23, and the second copper bar 40 can be locked on the second bearing portion 102 under the cooperation of the second stop portion 22 and the second sliding assembly 24. When it is necessary to lock the first copper bar 30 on the first bearing portion 101, it is only necessary to control the first sliding assembly 23 to move toward the direction close to the first stop portion 21 so as to abut against the first copper bar 30, so that the first copper bar 30 can be abutted against the first stop portion 21, thereby achieving the locking of the first copper bar 30 on the first bearing portion 101; when it is necessary to lock the second copper bar 40 on the second bearing portion 102, it is only necessary to control the second sliding assembly 24 to move toward the direction close to the second stop portion 22 so as to abut against the second copper bar 40, so that the second copper bar 40 can be abutted against the second stop portion 22, thereby achieving the locking of the second stop portion 22 on the second bearing portion 102. That is to say, the arrangement of the first stop portion 21 and the first sliding assembly 23, as well as the arrangement of the second stop portion 22 and the second sliding assembly 24 in this embodiment ensures that the position of the first copper bar 30 on the first load-bearing portion 101 and the position of the second copper bar 40 on the second load-bearing portion 102 are fixed, preventing the first copper bar 30 and the second copper bar 40 from being displaced due to vibration or external force. The entire fixing process is convenient and quick to operate, reducing labor intensity and labor costs, and the reliability of the copper bar locking is greatly enhanced through the double locking mechanism (the cooperation between the first stop portion 21 and the first sliding assembly 23, and the cooperation between the second stop portion 22 and the second sliding assembly 24).

[0052] Further, see Figure 1 as well as Figure 4 As shown, an observation portion 104 is provided between the first stop portion 21 and the second stop portion 22 in this embodiment for allowing a user to observe the relative position of the first copper bar 30 and the second copper bar 40 when locked. Specifically, during the process of overlapping and locking the first copper bar 30 and the second copper bar 40 using the locking member 60, the operator can observe the relative position of the surfaces of the first copper bar 30 and the second copper bar 40 and the locking position of the locking member 60 through the observation portion 104, thereby promptly detecting whether the overlapping position of the first copper bar 30 and the second copper bar 40 has shifted, effectively ensuring the reliability of the copper bar clamping device in this embodiment.

[0053] Further, see Figure 1As shown, the first sliding assembly 23 in this embodiment includes a first slider 231 and a first screw 232. The first slider 231 is movably mounted on the base 10 to at least cooperate with the first stopper 21 to lock the first copper busbar 30 to the first bearing portion 101; the first screw 232 is rotatably mounted on the base 10 and extends along the second direction. The first screw 232 is connected to the first slider 231 to drive the first slider 231 to reciprocate along the second direction.

[0054] Specifically, during the actual operation of the copper bar clamping device, after the first slider 231 is installed on the base 10, the first screw 232 is installed on the base 10 and one end of the first screw 232 is connected to the first slider 231. When the position of the first slider 231 needs to be changed, it is only necessary to rotate the first screw 232 in a clockwise direction or a counterclockwise direction to synchronously drive the first slider 231 to reciprocate along the second direction on the base 10. When the first slider 231 moves toward the direction close to the first stop portion 21 as the first screw 232 rotates, it can contact and abut the first copper bar 30 on the first bearing portion 101, thereby making the first copper bar 30 abut against the first stop portion 21, and finally achieving the fixation of the position of the first copper bar 30.

[0055] Further, see Figure 4 As shown, the base 10 in this embodiment is provided with a first fixing block 12 having a first threaded hole 121 therein, and a first slider 231 having a guide hole 2311 therein. A first screw rod 232 has a first threaded segment 2321 extending along its length and adapted to mate with the first threaded hole 121. The first screw rod 232 is sequentially inserted through the first threaded hole 121 and the guide hole 2311, with one end of the first screw rod 232 fixedly connected to the guide hole 2311. Specifically, in this embodiment, the first screw rod 232 and the first threaded hole 121 cooperate to enable the first slider 231 to reciprocate in the second direction on the base 10. Since the first screw rod 232 in this embodiment passes through the first threaded hole 121 and connects to the guide hole 2311 of the first slider 231, when the first screw rod 232 begins to rotate, the first screw rod 232 can move in the first threaded hole 121 via the first threaded segment 2321, thereby driving the first slider 231 to reciprocate in the second direction.

[0056] Further, see Figures 1 to 3 As shown, a pressing block 237 is provided on one side of the first slider 231 close to the first stop portion 21 in this embodiment. Specifically, the setting of the pressing block 237 can abut the first copper bar 30, thereby pressing the first copper bar 30 against the first stop portion 21.

[0057] Further, in order to facilitate the reciprocating movement of the first slider 231 along the second direction, see Figures 4 and 5 As shown, in this embodiment, one of the base 10 and the first slider 231 is provided with a positioning groove 11, and the other is provided with a positioning protrusion 233 that matches the positioning groove 11; wherein, the positioning groove 11 and the positioning protrusion 233 both extend along the second direction, and the length of the positioning groove 11 along the second direction is greater than the length of the positioning protrusion 233 along the second direction, so that the positioning protrusion 233 reciprocates along the length direction of the positioning groove 11. That is to say, in this embodiment, the positioning groove 11 can be provided on the base 10 and the positioning protrusion 233 can be provided on the first slider 231, or the positioning protrusion 233 can be provided on the base 10 and the positioning groove 11 can be provided on the first slider 231. Figure 4 The base 10 is provided with a positioning groove 11, an attachment Figure 5 The diagram shows a situation where the first slider 231 is provided with a positioning protrusion 233 .

[0058] Specifically, in this embodiment, the cooperation between the positioning groove 11 and the positioning protrusion 233 can ensure accurate positioning between the base 10 and the first slider 231, preventing the position of the first slider 231 on the base 10 from shifting, thereby affecting the locking of the first copper bar 30. At the same time, the length of the positioning groove 11 along the second direction in this embodiment is greater than the length of the positioning protrusion 233 along the second direction. In this way, the positioning groove 11 can provide movement space for the positioning protrusion 233, so that the positioning protrusion 233 can move in the second direction, thereby ensuring that the first slider 231 reciprocates in the second direction under the rotation of the first screw 232.

[0059] Further, see Figure 2 as well as Figure 5 As shown, in this embodiment, the positioning protrusion 233 is provided with a limiting hole 2331, and the first sliding assembly 23 includes a third stopper 234. The third stopper 234 is disposed on the side of the base 10 facing away from the first sliding assembly 23 and is connected to the limiting hole 2331 via a locking member 50. Specifically, during transportation and use of the copper bar clamping device, the positioning protrusion 233 may disengage from the positioning slot 11 due to shaking of the copper bar clamping device or external impact, causing the first slider 231 to fall off the base 10. To this end, in this embodiment, the third stopper 234 is disposed on the side of the base 10 facing away from the first sliding assembly 23, and the third stopper 234 is fixedly connected to the limiting hole 2331 via a locking member 50. This secures the first slider 231 and prevents it from falling off the base 10 due to shaking of the copper bar clamping device or external impact, effectively improving the stability and reliability of the operation of the first sliding assembly 23. Illustratively, the “locking member 50 ” in this embodiment includes structures such as screws or bolts.

[0060] Further, see Figure 1 As shown, the second sliding assembly 24 in this embodiment includes a second slider 241 and a second screw 242. The second slider 241 is movably disposed on a side of the first sliding assembly 23 facing away from the base 10 to at least cooperate with the second stop 22 to lock the second copper busbar 40 to the second bearing portion 102; the second screw 242 is rotatably mounted on the first sliding assembly 23 and extends along the first direction. The second screw 242 is connected to the second slider 241 to drive the second slider 241 to reciprocate along the first direction.

[0061] Specifically, during the actual operation of the copper bar clamping device, after the second slider 241 is installed on the first slider 231, the second screw 242 is installed on the second slider 241 and one end of the second screw 242 is fixedly connected to the second slider 241. When the position of the second slider 241 needs to be changed, it is only necessary to rotate the second screw 242 in a clockwise direction or a counterclockwise direction to synchronously drive the second slider 241 to reciprocate along the first direction on the first slider 231. When the second slider 241 moves toward the direction close to the second stop portion 22 as the second screw 242 rotates, it can contact and abut the second copper bar 40 on the second bearing portion 102, so that the second copper bar 40 abuts against the second stop portion 22, and finally the position of the second copper bar 40 is fixed.

[0062] Further, see Figure 1 as well as Figure 4 As shown, in this embodiment, a second fixing block 236 is provided on the first slider 231, and the second fixing block 236 has a second threaded hole 2361. A limiting portion 243 is provided on the side of the second slider 241 facing away from the second stop portion 22. The second screw rod 242 has a second threaded section 2421 extending along its length and adapted to fit the second threaded hole 2361. The second screw rod 242 is inserted into the second threaded hole 2361, and one end of the second screw rod 242 is fixedly connected to the limiting portion 243. Specifically, in this embodiment, the interaction between the second screw rod 242 and the second threaded hole 2361 enables the second slider 241 to reciprocate along the first direction on the first slider 231. Since the second screw 242 in this embodiment passes through the second threaded hole 2361 and is connected to the limiting portion 243 on the second slider 241, when the second screw 242 starts to rotate, the second screw 242 can run on the second threaded hole 2361 through the second threaded segment 2421, thereby driving the second slider 241 to reciprocate along the first direction.

[0063] Specifically, the limiting portion 243 and the second slider 241 in this embodiment are fixedly connected via a locking member 50. For example, the "locking member 50" in this embodiment includes a structure such as a screw or a bolt.

[0064] Further, in order to facilitate the reciprocating movement of the second slider 241 along the first direction, see Figure 4 As shown, in this embodiment, one of the second slider 241 and the first sliding assembly 23 is provided with a slide groove (not shown in the drawings), and the other is provided with a slide rail 235 adapted to the slide groove. In other words, in this embodiment, the slide groove can be provided on the second slider 241 and the slide rail 235 can be provided on the first slider 231, or the slide rail 235 can be provided on the second slider 241 and the slide groove can be provided on the first slider 231. Figure 1 And attached Figure 4 2 shows a case where the second slider 241 is provided with a slide groove and the first slider 231 is provided with a slide rail 235. For example, the "slide groove" in this embodiment includes a dovetail groove, and the "slide rail 235" includes a dovetail track structure. Of course, in other embodiments of the present application, the slide groove may also include other polygonal structures. As long as other variations are based on the concept of the present application, they are all within the scope of protection of the present application.

[0065] Specifically, in this embodiment, the cooperation between the slide groove and the slide rail 235 can improve the stability of the connection between the second slider 241 and the first sliding assembly 23, and prevent the second slider 241 from being displaced on the first slider 231 due to vibration or external force. The setting of the slider and the slide groove reduces the difficulty of assembly between the second slider 241 and the first sliding assembly 23.

[0066] Further, see Figure 1 as well as Figure 6 As shown, the first sliding assembly 23 and the second sliding assembly 24 in this embodiment each include at least one; wherein, when the first sliding assembly 23 includes multiple, the multiple first sliding assemblies 23 are independent of each other and arranged in sequence along the first direction; when the second sliding assembly 24 includes multiple, the multiple second sliding assemblies 24 are independent of each other and arranged in sequence along the second direction.

[0067] Specifically, in this embodiment, the first copper bar 30 can be locked on the first bearing portion 101 by the mutual cooperation between the first sliding component 23 and the first stop portion 21, and the second copper bar 40 can be locked on the second stop portion 22 by the mutual cooperation between the second sliding component 24 and the second stop portion 22. Specifically, when the first sliding component 23 in this embodiment includes multiple first sliding components 23, the multiple first sliding components 23 are independent of each other and arranged in sequence along the first direction. Such an arrangement can not only improve the reliability of the first sliding component 23 in locking the first copper bar 30, so that the multiple first sliding components 23 can lock different positions of the first copper bar 30, reducing the risk of the copper bar 30 shifting due to vibration or impact, but also enhance the adaptability of the first sliding component 23, so that the multiple independently arranged first sliding components 23 can adapt to first copper bars 30 of different sizes, thereby improving the applicability of the copper bar clamping device. When the second sliding assembly 24 in this embodiment includes multiple second sliding assemblies 24, the multiple second sliding assemblies 24 are independent of each other and arranged in sequence along the second direction. Such an arrangement can not only improve the reliability of the second sliding assembly 24 in locking the second copper bus 40, so that the multiple second sliding assemblies 24 can lock different positions of the second copper bus 40, reducing the risk of the second copper bus 40 shifting due to vibration or impact, but also enhance the adaptability of the second sliding assembly 24, so that the multiple independently arranged second sliding assemblies 24 can adapt to the second copper bus 40 of different sizes, thereby improving the scope of application of the copper bus clamping device.

[0068] Optionally, the "first sliding assembly 23" and the "second sliding assembly 24" in this embodiment can be set to one, or can be set to two or more. Figure 1 And attached Figure 6 FIG. 2 shows a case where the number of the first sliding assembly 23 is one and the number of the second sliding assembly 24 is two.

[0069] Further, see Figure 6 As shown, the first and second carrier portions 101, 102 of this embodiment each include a flat carrier surface 1011 or a concave-convex carrier surface 1021. This configuration ensures that the first and second carrier portions 101, 102 can support copper busbars of various shapes, thereby expanding the range of applications for the copper busbar clamping device. In other words, the first and second carrier portions 101, 102 of this embodiment can be machined according to the bent shape of the copper busbar to ensure that the copper busbar fits snugly on the first and second carrier portions 101, 102.

[0070] Specifically, see Figure 1 、 Figure 3 as well as Figure 7As shown, in one embodiment of the present application, the first carrying portion 101 and the second carrying portion 102 are both carrying planes 1011, so that the copper busbar without a bending section can be locked and fixed. Figure 6 as well as Figure 8 As shown, in another embodiment of the present application, the first bearing portion 101 is a bearing plane 1011, and the second bearing portion 102 is a bearing concave-convex surface 1021. In this way, the copper busbar without a bending section and the copper busbar with a bending section can be locked and fixed. Of course, in another embodiment of the present application that is not shown, the first bearing portion 101 is a bearing concave-convex surface 1021, and the second bearing portion 102 is a bearing plane 1011. In this way, the copper busbar without a bending section and the copper busbar with a bending section can be locked and fixed.

[0071] Further, see Figure 1 As shown, the base 10 in this embodiment is provided with a support portion 13, and a limit fixing groove 131 is provided on the support portion 13. Specifically, the setting of the support portion 13 can provide support for the base 10, and the setting of the limit fixing groove 131 facilitates fixing the base 10 on a suitable work platform or machine.

[0072] Specifically, the working principle of the copper busbar clamping device in this application is as follows:

[0073] First, place the first copper bar 30 on the first carrier portion 101 and the second copper bar 40 on the second carrier portion 102 so that the first copper bar 30 and the second copper bar 40 are overlapped at one end of the avoidance portion 103;

[0074] Next, the first screw 232 is rotated to drive the first slider 231 to move in the second direction to abut against the first copper bar 30, and the first copper bar 30 is pressed against the first stop 21; the second screw 242 is rotated to drive the second slider 241 to move in the first direction to abut against the second copper bar 40, and the second copper bar 40 is pressed against the second stop 22;

[0075] Thereafter, the locking member 60 is inserted into the junction of the first copper bar 30 and the second copper bar 40 , and a torsional force is applied to the locking member 60 to lock the first copper bar 30 and the second copper bar 40 .

[0076] In combination with the above embodiments, it can be known that the present application provides a locking mechanism 20 on the base 10, which can lock the first copper busbar 30 and the second copper busbar 40 on the first load-bearing part 101 and the second load-bearing part 102 respectively, thereby preventing the first copper busbar 30 and the second copper busbar 40 from rotating and slipping during the locking process of the locking member 60, thereby causing the overlapping position to shift, and the entire overlapping locking process does not require repeated adjustment of the copper busbar position, effectively improving the installation efficiency of the copper busbar overlap and reducing manual labor intensity and labor costs.

[0077] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0078] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0079] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
