Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electronic components, and in particular to a bridge-type clamping assembly and a drawer-type circuit breaker. Background Art
[0002] Bridge-type clamping assemblies are widely used in switching electrical appliances such as circuit breakers, relays, and household appliances. The reliable use of switching electrical appliances depends largely on the performance of the bridge-type clamping assemblies.
[0003] Taking a drawer-type circuit breaker as an example, the drawer-type circuit breaker includes a bridge-type clamping assembly, a drawer base, and a circuit breaker body. The circuit breaker body is movable relative to the drawer base. The drawer base is connected to the circuit breaker body via the bridge-type clamping assembly.
[0004] Based on the structure of the existing bridge-type clamping assembly, the heat dissipation effect of the drawer-type circuit breaker is poor, resulting in a high temperature rise inside the drawer-type circuit breaker, which may affect the performance of the drawer-type circuit breaker. Utility Model Content
[0005] The present application provides a bridge-type clamping assembly and a drawer-type circuit breaker, which can increase the contact area between the first clamping pieces of the bridge-type clamping assembly and the first clamping pieces, increase the contact area between the bridge-type clamping assembly and the busbar, and thereby reduce the temperature generated at the contact points between the first clamping pieces and the first clamping pieces and at the contact points between the bridge-type clamping assembly and the busbar, thereby reducing the temperature rise of the bridge-type clamping assembly.
[0006] In a first aspect, the present application provides a bridge-type clamping assembly mounted on a drawer base. The bridge-type clamping assembly includes a first clip group and a second clip group. The second clip group is movably connected to the first clip group. The second clip group cooperates with the first clip group to form a first clamping opening and a second clamping opening. The first clamping opening and the second clamping opening open in opposite directions. The first clamping opening is used to clamp a first busbar, and the second clamping opening is used to clamp a second busbar.
[0007] The first clip assembly includes a first clamping piece and at least one first clamping piece that cooperate with each other. The first clamping piece is located on the side of the first clip that faces the second clip assembly. The second clip assembly includes a second clamping piece and at least one second clamping piece that cooperate with each other. The second clamping piece is located on the side of the second clip that faces the first clip assembly. The second clamping piece and the first clamping piece form a first clamping opening and a second clamping opening.
[0008] In the example of the present application, during the use of the bridge-type clamping assembly, the first clamp can apply a force to the first clamping piece, and the second clamp can apply a force to the second clamping piece, so that the fit between the first clamp and the first busbar is more reliable, and the fit between the second clamp and the second busbar is more reliable, reducing the connection between the bridge-type clamping assembly and the first busbar, and reducing the possibility of a higher temperature rise due to unreliable contact at the connection between the bridge-type clamping assembly and the second busbar.
[0009] In addition, compared to the prior art, in which the arrangement direction of multiple clips in the clip group is perpendicular to the movement direction of the clamp, in the example of the present application, the arrangement direction of at least one first clip in the first clip group and the first clamping piece is the same as the movement direction of the first clamp. Therefore, the contact area between the first clamping piece and the first busbar in the example of the present application is greater than the contact area between the clip and the first busbar in the prior art, and the contact area between the first clamping piece and the first clip in the example of the present application, as well as the contact area between two adjacent first clips, are both greater than the contact area between two adjacent clips in the prior art. Based on the law of resistance, it is known that the contact resistance between different conductors is inversely proportional to the contact area. Based on Joule's law, it is known that when the current is constant, the heat generated at the contact point of different conductors is inversely proportional to the contact area. Therefore, the temperature rise generated at the contact point between the bridge-type clamping assembly and the first busbar, the contact point between the bridge-type clamping assembly and the second busbar, and the contact point between the first clamping piece and the first clip provided in the example of the present application is relatively small.
[0010] In some possible implementations, the first clip set includes a first clamping segment, a first connecting segment, and a second clamping segment, and the first connecting segment connects the first clamping segment and the second clamping segment.
[0011] The second clamping piece group includes a third clamping section, a second connecting section and a fourth clamping section. The second connecting section connects the third clamping section and the fourth clamping section. The third clamping section cooperates with the first clamping section to form a first clamping opening. The fourth clamping section cooperates with the second clamping section to form a second clamping opening.
[0012] Based on the above, the first clamping section and the third clamping section can cooperate to form a first clamping opening to clamp the first busbar. The second clamping section and the fourth clamping section can cooperate to form a second clamping opening to clamp the second busbar, thereby achieving electrical connection between the bridge clamping assembly, the first busbar, and the second busbar.
[0013] In some possible implementations, the first clamping piece includes a first sub-segment, a first connecting sub-segment, and a second sub-segment, and the first connecting sub-segment connects the first sub-segment and the second sub-segment.
[0014] The first clip includes a third sub-segment, a second sub-connecting segment and a fourth sub-segment, the second sub-connecting segment connects the third sub-segment and the fourth sub-segment, the third sub-segment and the first sub-segment cooperate to form a first clamping segment, the second sub-connecting segment and the first sub-connecting segment cooperate to form a first connecting segment, and the fourth sub-segment and the second sub-segment cooperate to form a second clamping segment.
[0015] During use of the bridge-type clamping assembly, the third sub-segment can provide a force to the first sub-segment, ensuring more reliable contact between the first sub-segment and the first busbar, thereby reducing the possibility of a high temperature rise due to an unreliable connection between the first sub-segment and the first busbar, and thus reducing the temperature rise of the bridge-type clamping assembly during use. The fourth sub-segment can provide a force to the second sub-segment, ensuring more reliable contact between the second sub-segment and the second busbar, thereby reducing the possibility of a high temperature rise due to an unreliable connection between the second sub-segment and the second busbar, and thus reducing the temperature rise of the bridge-type clamping assembly during use.
[0016] In some possible implementations, an abutting section is provided between the first sub-segment and the first connecting sub-segment, the abutting section being arranged at an angle to the first connecting sub-segment. The third sub-segment cooperates with the second connecting sub-segment to form a first abutting protrusion, and the first abutting protrusion abuts against the abutting section.
[0017] Because the abutting section is provided between the first sub-section and the first connecting sub-section, and the first abutting protrusion is formed by the cooperation of the third sub-section and the second connecting sub-section, the cooperation between the first abutting protrusion and the abutting section can limit the position of the second connecting sub-section relative to the first connecting sub-section, thereby reducing the possibility of displacement of the second connecting sub-section relative to the first connecting sub-section.
[0018] Since the first sub-segment and the first sub-connecting segment are part of the first clamping piece, and the third sub-segment and the second sub-connecting segment are part of the first clip, the first abutting protrusion and the abutting segment cooperate to limit the position of the first clip relative to the first clamping piece, reducing the possibility of displacement of the first clip relative to the first clamping piece, ensuring the reliable cooperation between the first clip and the first clamping piece, and further reducing the possibility of a high temperature rise caused by poor contact between the first clamping piece and the first clip.
[0019] In some possible implementations, the first sub-connecting segment cooperates with the second sub-segment to form a first abutting groove, and the second sub-connecting segment cooperates with the fourth sub-segment to form a second abutting protrusion, which abuts against the first abutting groove.
[0020] Since the first abutment groove is formed by the cooperation of the second sub-segment and the first sub-connecting segment, and the second abutment protrusion is formed by the cooperation of the fourth sub-segment and the second sub-connecting segment, the cooperation of the second abutment protrusion and the first abutment groove can limit the position of the second sub-connecting segment relative to the first sub-connecting segment, reducing the possibility of the second sub-connecting segment being displaced relative to the first sub-connecting segment. Furthermore, since the second sub-segment and the first sub-connecting segment are part of the first clamping piece, and the fourth sub-segment and the second sub-connecting segment are part of the first clip, the cooperation between the second abutment protrusion and the first abutment groove can limit the position of the first clip relative to the first clamping piece, reducing the possibility of the first clip being displaced relative to the first clamping piece, ensuring the reliability of the cooperation between the first clip and the first clamping piece, and further reducing the possibility of a high temperature rise due to poor contact between the first clamping piece and the first clip.
[0021] In addition, on the basis of the cooperation between the first abutment protrusion and the abutment section, a second abutment protrusion is provided to cooperate with the first abutment groove. Since the first abutment protrusion is provided at one end of the second sub-connecting section close to the third sub-section, and the second abutment protrusion is provided at one end of the second sub-connecting section close to the fourth sub-section, the cooperation between the first abutment protrusion and the abutment section and the cooperation between the second abutment protrusion and the first abutment groove can limit the position of the first sub-connecting section relative to the second sub-connecting section in different directions, further ensuring the connection reliability between the first clamping piece and the first clamping piece, and reducing the possibility of a higher temperature rise due to poor contact between the first clamping piece and the first clamping piece.
[0022] In some possible implementations, a first limiting structure is provided on the side of the first sub-connecting segment facing the second sub-connecting segment, and a second limiting structure is provided on the side of the second sub-connecting segment facing the first sub-connecting segment, and the second limiting structure cooperates with the first limiting structure.
[0023] Since the first limiting structure is provided on the first sub-connecting segment and the second limiting structure is provided on the second sub-connecting segment, the cooperation between the first limiting structure and the second limiting structure can further ensure the cooperation reliability between the first sub-connecting segment and the second sub-connecting segment, further reduce the possibility of displacement of the second sub-connecting segment relative to the first sub-connecting segment, thereby ensuring the connection reliability between the first clamping piece and the first clamping piece, and reducing the possibility of a high temperature rise due to poor contact between the first clamping piece and the first clamping piece.
[0024] In some possible implementations, the first clamping piece further includes a limiting section, which is provided at an end of the second sub-segment away from the first sub-connecting section and cooperates with an end of the fourth sub-segment away from the second sub-connecting section.
[0025] By providing the limiting segment, the displacement amplitude of the fourth subsegment relative to the second subsegment in the direction away from the second connecting subsegment can be reduced, thereby ensuring the connection reliability between the fourth subsegment and the second subsegment.
[0026] In some possible implementations, the first clamping piece is in surface contact with the first busbar, and / or the first clamping piece is in surface contact with the second busbar.
[0027] Compared to existing bridge-type clamping assemblies, in which the bridge-type clamping assembly contacts the first busbar and the second busbar, in this application example, the first clamping piece contacts the first busbar surface, increasing the contact area between the first clamping piece and the first busbar, reducing the temperature rise generated at the contact point between the first clamping piece and the first busbar, and thus reducing the temperature rise generated by the bridge-type clamping assembly during use.
[0028] In the example of this application, the first clamping piece contacts the second busbar surface, which increases the contact area between the first clamping piece and the second busbar, reduces the temperature rise generated at the contact point between the first clamping piece and the second busbar, and thus can reduce the temperature rise generated by the bridge-type clamping assembly during use.
[0029] In some possible implementations, the bridge clamping assembly further includes a first connecting structure and a second connecting structure. The first connecting structure abuts against a side of the first clip group facing away from the second clip group. The second connecting structure abuts against a side of the second clip group facing away from the first clip group.
[0030] The first connecting structure is arranged on the side of the first clip group away from the second clip group, and applies a force to the first clip group toward the second clip group. The second connecting structure is arranged on the side of the second clip group away from the first clip group, and applies a force to the second clip group toward the first clip group. Since the force applied to the first clip group by the first connecting structure is opposite to the force applied to the second clip group by the second connecting structure, the force applied to the first busbar and the second busbar by the first clip group is opposite to the force applied to the first busbar and the second busbar by the second clip group, making the connection between the bridge-type clamping assembly and the first busbar and the second busbar more reliable.
[0031] In a second aspect, the present application provides a circuit breaker. The circuit breaker includes a drawer base, a circuit breaker body, and a bridge-type clamping assembly provided in each possible implementation of the first aspect. The bridge-type clamping assembly connects the drawer base and the circuit breaker body.
[0032] The beneficial effects of the bridge-type clamping assembly provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

[0048] Based on the above, the present application example provides a bridge-type clamping assembly and a drawer-type circuit breaker.
[0049] In order to enable people skilled in the art to better understand the present application, the bridge-type clamping assembly and the drawer-type circuit breaker provided in the example of the present application will be clearly and completely described below in conjunction with the accompanying drawings.
[0050] For example, the present application provides a drawer-type circuit breaker, which may include a drawer base, a circuit breaker body, and a bridge-type clamping assembly. The bridge-type clamping assembly connects the drawer base and the circuit breaker body to achieve electrical connection between the drawer base and the circuit breaker body.
[0051] The drawer seat may have a accommodating cavity, and the circuit breaker body may be installed in the accommodating cavity, so as to facilitate the electrical connection between the circuit breaker body and the drawer seat. In the event of a failure of the circuit breaker body, the circuit breaker body may be shaken out of the accommodating cavity and replaced with a spare circuit breaker body, thereby improving the maintenance efficiency of the drawer-type circuit breaker. The drawer-type circuit breaker may also be used as an isolator. In the event that a circuit or equipment requires maintenance, the circuit breaker body may be shaken out of the accommodating cavity to isolate the circuit in sections, thereby ensuring the safety of maintenance personnel during the maintenance of the circuit or equipment. Here, the circuit refers to the circuit to which the drawer-type circuit breaker is electrically connected, and the equipment refers to the equipment that is directly or indirectly electrically connected to the drawer-type circuit breaker.
[0052] A first busbar can be connected to the drawer housing, and a second busbar can be connected to the circuit breaker body. Each first busbar can be connected to a bridge-type clamping assembly, with the end of the bridge-type clamping assembly facing away from the first busbar connected to the second busbar. Multiple bridge-type clamping assemblies can also be connected to a first busbar, with the ends of the bridge-type clamping assemblies facing away from the first busbar connected to the second busbar. This example application does not impose specific limitations on this.
[0053] The structure of the circuit breaker body in the example of this application is consistent with the structure of the circuit breaker body in the prior art, and will not be described in detail here. The specific structure of the bridge-type clamping assembly is detailed below and will not be described in detail here.
[0054] Next, the bridge-type clamping assembly mentioned in the drawer-type circuit breaker is described in detail.
[0055] Exemplarily, the present application provides a bridge-type clamping assembly. Figure 1 A schematic diagram of the structure of a bridge-type clamping assembly provided as an example in this application is shown. Figure 2 For the exploded structure diagram of the first clip group provided in this application example, please refer to Figure 1 and Figure 2 The bridge-type clamping assembly 100 is mounted on the drawer seat. The bridge-type clamping assembly 100 may include a first clamping piece group 110 and a second clamping piece group 120 .
[0056] The second clip group 120 is movably connected to the first clip group 110. The second clip group 120 cooperates with the first clip group 110 to form a first clamping opening 130 and a second clamping opening 140. The opening directions of the first clamping opening 130 and the second clamping opening 140 are opposite to each other. The first clamping opening 130 is used to clamp the first busbar, and the second clamping opening 140 is used to clamp the second busbar.
[0057] The first clip assembly 110 includes a first clamping piece 111 and at least one first clip 112 that cooperate with each other. The first clamping piece 111 is located on the side of the first clip 112 that faces the second clip assembly 120. The second clip assembly 120 includes a second clamping piece and at least one second clip that cooperate with each other. The second clamping piece is located on the side of the second clip that faces the first clip assembly 110. The second clamping piece and the first clamping piece 111 form a first clamping opening 130 and a second clamping opening 140.
[0058] The bridge-type clamping assembly 100 can be applied to switching devices such as circuit breakers, contactors, relays, and disconnectors. This application example only describes the bridge-type clamping assembly 100 as being applicable to a drawer-type circuit breaker among circuit breakers.
[0059] The first clip group 110 and the second clip group 120 may be connected by an elastic member. A connecting structure may also be provided on the side of the first clip group 110 facing away from the second clip group 120. This connecting structure can apply a force to the first clip group 110 toward the second clip group 120. A connecting structure may also be provided on the side of the second clip group 120 facing away from the first clip 112. This connecting structure can apply a force to the second clip group 120 toward the first clip group 110. The first clip group 110 and the second clip group 120 may also be connected by other means, as long as the opening sizes of the first and second clamping openings 130, 140 can be adjusted so that the first clamping opening 130 clamps the first busbar and the second clamping opening 140 clamps the second busbar.
[0060] The end of the first busbar away from the first clamping opening 130 can be electrically connected to the drawer base, and the first busbar can be fixedly connected to the drawer base body via threaded connection, riveting, or other methods. Electrical equipment can be electrically connected to the drawer base or to the first busbar via wires, etc. The end of the second busbar away from the second clamping opening 140 can be connected to the circuit breaker body.
[0061] Alternatively, the first busbar can be connected to the circuit breaker body, and the second busbar can be connected to the drawer seat. The example of this application does not impose any specific restrictions on the connection relationship between the first busbar, the second busbar, the circuit breaker body and the drawer seat, as long as it is ensured that the electrical connection between the first busbar, the second busbar, the circuit breaker body and the drawer seat can be achieved through the bridge-type clamping assembly 100.
[0062] The first clip set 110 may include a first clamping piece 111 and at least one first clip 112. The first clamping piece 111 may be disposed on a side of the first clip 112 facing away from the second clip set 120.
[0063] The first clamping piece 112 and the first clamping piece 111 may be made of the same material, or may be made of different materials. This example of the application does not impose any specific limitation on this.
[0064] The first clip 112 and the first clamping piece 111 can cooperate with each other by fixed connection, mutual abutment or other connection methods. Two adjacent first clips 112 can also cooperate with each other by fixed connection, mutual abutment or other connection methods, and this application example does not make specific restrictions on this.
[0065] The arrangement direction of the first clamping piece 111 and the first clamping piece 112 can be the same as the movable direction of the first clamping opening 130. The structure of the first clamping piece 111 can be exactly the same as that of the first clamping piece 112, or the structure of the first clamping piece 111 can be the same as that of the first clamping piece 112. The structures of multiple first clamping pieces 112 can be exactly the same, or the structures of multiple first clamping pieces 112 can be different. This example of the present application does not impose any specific restrictions on this. As long as the first clamping piece 111 and the second clamping piece are matched to form the first clamping opening 130 and the second clamping opening 140, the first busbar and the second busbar can be clamped at the same time to achieve electrical connection between the first busbar, the second busbar and the bridge-type clamping assembly 100.
[0066] The connection between adjacent first clips 112 is similar to the connection between the first clip 112 and the first clamping piece 111 , and the following description will only take the matching between the first clip 112 and the first clamping piece 111 as an example.
[0067] The first clamping piece 111 and the first clamping piece 112 can directly cooperate with each other, and a spacer can also be provided between the first clamping piece 111 and the first clamping piece 112. One side of the spacer can be connected to the first clamping piece 111, and the other side of the spacer can be connected to the first clamping piece 112. The example of this application does not limit the specific implementation method of the first clamping piece group 110.
[0068] The specific implementation of the second clip group 120 is similar to that of the first clip group 110. The number of second clips included in the second clip group 120 can be equal to or different from the number of first clips 112 in the first clip group 110, and this is not specifically limited in this example. The specific structure of the second clip group 120 can refer to the relevant description of the specific structure of the first clip group 110.
[0069] The first clamping piece 111 cooperates with the second clamping piece to form a first clamping opening 130 and a second clamping opening 140 .
[0070] When the first clamping opening 130 clamps the first busbar, both the first clamping piece 111 and the second clamping piece can be in contact with the surface of the first busbar, and both the first clamping piece 111 and the second clamping piece can be in contact with the first busbar line. One of the first clamping piece 111 and the second clamping piece can also be in contact with the surface of the first busbar, and the other can be in contact with the first busbar line. This application example does not impose any specific restrictions on this.
[0071] The specific implementation method of the second clamping opening 140 clamping the second busbar is similar to the specific implementation method of the first clamping opening 130 clamping the first busbar. For details, please refer to the above specific description of the first clamping opening 130 clamping the first busbar.
[0072] According to the bridge-type clamping assembly 100 provided in the example of this application, the first clamping piece group 110 and the second clamping piece group 120 can cooperate to form a first clamping opening 130 and a second clamping opening 140. Specifically, the first clamping piece 111 and the second clamping piece can cooperate to form the first clamping opening 130 and the second clamping opening 140. The first clamping opening 130 can clamp the first busbar to achieve an electrical connection between the bridge-type clamping assembly 100 and the first busbar. The second clamping opening 140 can clamp the second busbar to achieve an electrical connection between the bridge-type clamping assembly 100 and the second busbar. Since the first clamping opening and the second clamping opening 140 are both provided in the bridge-type clamping assembly 100, and one of the first busbar and the second busbar can be connected to the circuit breaker body and the other can be connected to the drawer seat, the electrical connection between the circuit breaker body and the drawer seat can be achieved through the bridge-type clamping assembly 100.
[0073] In the example of the present application, during the use of the bridge-type clamping assembly 100, the first clamping piece 112 can apply a force to the first clamping piece 111, and the second clamping piece can apply a force to the second clamping piece, so that the fit between the first clamping opening 130 and the first busbar is more reliable, and the fit between the second clamping opening 140 and the second busbar is more reliable, thereby reducing the possibility of a higher temperature rise due to unreliable contact at the connection between the bridge-type clamping assembly 100 and the first busbar, and reducing the possibility of a higher temperature rise due to unreliable contact at the connection between the bridge-type clamping assembly 100 and the second busbar.
[0074] In addition, compared to the prior art, in which the arrangement direction of the multiple clips in the clip group is perpendicular to the movement direction of the clamp, in the example of the present application, the arrangement direction of at least one first clip 112 in the first clip group 110 and the first clamping piece 111 is the same as the movement direction of the first clamp 130. Therefore, the contact area between the first clamping piece 111 and the first busbar in the example of the present application is greater than the contact area between the clip and the first busbar in the prior art, and the contact area between the first clamping piece 111 and the first clip 112 in the example of the present application, as well as the contact area between two adjacent first clips 112, are greater than the contact area between two adjacent clips in the prior art. Based on the law of resistance, it is known that the contact resistance between different conductors is inversely proportional to the contact area. Based on Joule's law, it is known that when the current is constant, the heat generated at the contact point of different conductors is inversely proportional to the contact area. Therefore, the temperature rise generated at the contact points between the bridge-type clamping assembly 100 and the first busbar, the contact points between the bridge-type clamping assembly 100 and the second busbar, and the contact points between the first clamping piece 111 and the first clamping piece 112 provided in the example of this application is relatively small.
[0075] Based on the bridge-type clamping assembly 100 provided in the above example, the first clamping piece assembly 110 may include a first clamping segment, a first connecting segment, and a second clamping segment. The first connecting segment connects the first clamping segment and the second clamping segment. The second clamping piece assembly 120 may include a third clamping segment, a second connecting segment, and a fourth clamping segment. The second connecting segment connects the third clamping segment and the fourth clamping segment. The third clamping segment cooperates with the first clamping segment to form a first clamping opening 130, and the fourth clamping segment cooperates with the second clamping segment to form a second clamping opening 140.
[0076] The first clamping section and the first connecting section may be arranged at an angle, and the angle formed by the first clamping section and the first connecting section may be an obtuse angle. The second clamping section and the first connecting section may be arranged at an angle, and the angle formed by the second clamping section and the first connecting section may be an obtuse angle. The first clamping section and the second clamping section may be parallel, and the first clamping section and the second clamping section may also be arranged at an angle.
[0077] The third clamping section and the second connecting section may be arranged at an angle, and the angle formed by the third clamping section and the second connecting section may be an obtuse angle. The fourth clamping section and the second connecting section may be arranged at an angle, and the angle formed by the fourth clamping section and the second connecting section may be an obtuse angle. The third clamping section and the fourth clamping section may be parallel, and the third clamping section and the fourth clamping section may also be arranged at an angle.
[0078] The first connecting segment and the second connecting segment can be roughly parallel. Specifically, the angle between the first connecting segment and the second connecting segment is greater than or equal to 0 degrees and less than or equal to 10 degrees. This application example does not impose any specific restrictions on this.
[0079] The example of this application does not limit the specific implementation method of the first clamping section, the second clamping section, the third clamping section and the fourth clamping section, as long as the first clamping section and the third clamping section cooperate to form the first clamping opening 130, the second clamping section and the fourth clamping section cooperate to form the second clamping opening 140, and on the basis of ensuring that the first clamping opening 130 clamps the first busbar, the second clamping opening 140 can clamp the second busbar.
[0080] Based on the above, the first clamping section and the third clamping section can cooperate to form a first clamping opening 130 to clamp the first busbar. The second clamping section and the fourth clamping section cooperate to form a second clamping opening 140 to clamp the second busbar, thereby achieving electrical connection between the bridge clamping assembly 100, the first busbar, and the second busbar.
[0081] The structures of the first clip set 110 and the second clip set 120 are similar. Hereinafter, the specific structures of the first clip set 110 and the second clip set 120 will be described by taking the first clip set 110 as an example.
[0082] Based on the bridge-type clamping assembly 100 provided in the above example, Figure 3 This is a schematic diagram of the structure of a first clamping piece provided as an example in this application. Figure 4 For a structural diagram of a first clip provided in this application example, please refer to Figures 1 to 4 The first clamping piece 111 may include a first sub-segment 1111 , a first sub-connecting segment 1112 and a second sub-segment 1113 , and the first sub-connecting segment 1112 connects the first sub-segment 1111 and the second sub-segment 1113 .
[0083] The first clip 112 may include a third sub-segment 1121, a second sub-connecting segment 1122 and a fourth sub-segment 1123, the second sub-connecting segment 1122 connects the third sub-segment 1121 and the fourth sub-segment 1123, the third sub-segment 1121 cooperates with the first sub-segment 1111 to form a first clamping segment, the second sub-connecting segment 1122 cooperates with the first sub-connecting segment 1112 to form a first connecting segment, and the fourth sub-segment 1123 cooperates with the second sub-segment 1113 to form a second clamping segment.
[0084] The third subsegment 1121 may abut against the first subsegment 1111 , or may be connected to the first subsegment 1111 via other structures, or the first subsegment 1111 and the third subsegment 1121 may be in surface contact.
[0085] The second sub-connecting segment 1122 may abut against the first sub-connecting segment 1112 , or the first sub-connecting segment 1112 may be connected to the second sub-connecting segment 1122 via other structures, so that the first sub-connecting segment 1112 and the second sub-connecting segment 1122 are in surface contact.
[0086] The fourth sub-segment 1123 may abut against the second sub-segment 1113 , the second sub-segment 1113 may also be connected to the fourth sub-segment 1123 via other structures, and the second sub-segment 1113 and the fourth sub-segment 1123 may be in surface contact.
[0087] Based on the above, during use of the bridge-type clamping assembly 100, the third sub-segment 1121 can provide a force to the first sub-segment 1111, thereby ensuring more reliable contact between the first sub-segment 1111 and the first busbar, thereby reducing the possibility of a high temperature rise due to an unreliable connection between the first sub-segment 1111 and the first busbar, and thus reducing the temperature rise of the bridge-type clamping assembly 100 during use. The fourth sub-segment 1123 can provide a force to the second sub-segment 1113, thereby ensuring more reliable contact between the second sub-segment 1113 and the second busbar, thereby reducing the possibility of a high temperature rise due to an unreliable connection between the second sub-segment 1113 and the second busbar, and thus reducing the temperature rise of the bridge-type clamping assembly 100 during use.
[0088] Based on the bridge type clamping assembly 100 provided in the above example, please refer to Figures 2 to 4 An abutting section 1114 is provided between the first sub-section 1111 and the first connecting sub-section 1112. The abutting section 1114 is arranged at an angle to the first connecting sub-section 1112. The third sub-section 1121 cooperates with the second connecting sub-section 1122 to form a first abutting protrusion 1124, which abuts against the abutting section 1114.
[0089] The abutment section 1114 is disposed between the first sub-section 1111 and the first connecting sub-section 1112. The abutment section 1114 may be disposed at an angle relative to at least one of the first sub-section 1111 and the first connecting sub-section 1112. The surface of the abutment section 1114 that mates with the first abutment protrusion 1124 may be flat or may have a groove. This example does not impose any specific limitations on the molding method of the abutment section 1114.
[0090] The first abutting protrusion 1124 can be a protrusion formed by the angled arrangement between the third sub-segment 1121 and the second connecting sub-segment 1122. The first abutting protrusion 1124 can also be a protrusion provided at the connection between the third sub-segment 1121 and the second connecting sub-segment 1122. This example of the application does not impose any specific limitation on the molding method of the first abutting protrusion 1124. It is sufficient as long as the first abutting protrusion 1124 can abut against the abutting segment 1114 during use of the bridge-type clamping assembly 100.
[0091] Based on the above, since the abutting section 1114 is provided between the first sub-section 1111 and the first connecting sub-section 1112, and the first abutting protrusion 1124 is formed by the cooperation between the third sub-section 1121 and the second connecting sub-section 1122, the cooperation between the first abutting protrusion 1124 and the abutting section 1114 can limit the position of the second connecting sub-section 1122 relative to the first connecting sub-section 1112, thereby reducing the possibility of displacement of the second connecting sub-section 1122 relative to the first connecting sub-section 1112.
[0092] Furthermore, since the first sub-segment 1111 and the first sub-connecting segment 1112 are part of the first clamping piece 111, and the third sub-segment 1121 and the second sub-connecting segment 1122 are part of the first clip 112, the cooperation between the first abutting protrusion 1124 and the abutting segment 1114 can limit the position of the first clip 112 relative to the first clamping piece 111, reducing the possibility of displacement of the first clip 112 relative to the first clamping piece 111, ensuring the reliability of the cooperation between the first clip 112 and the first clamping piece 111, and further reducing the possibility of a high temperature rise caused by poor contact between the first clamping piece 111 and the first clip 112.
[0093] Based on the bridge type clamping assembly 100 provided in the above example, please refer to Figures 2 to 4 The first sub-connecting segment 1112 cooperates with the second sub-segment 1113 to form a first abutting groove 1115 . The second sub-connecting segment 1122 cooperates with the fourth sub-segment 1123 to form a second abutting protrusion 1125 , which abuts against the first abutting groove 1115 .
[0094] The first abutment groove 1115 can be a groove formed by the second sub-segment 1113 and the first sub-connecting segment 1112 at an angle, or the first abutment groove 1115 can be a groove arranged at the connection between the second sub-segment 1113 and the first sub-connecting segment 1112. The example of this application does not impose any specific restrictions on the forming method of the first abutment groove 1115.
[0095] The second abutting protrusion 1125 can be a protrusion formed by the fourth sub-segment 1123 and the second connecting sub-segment 1122 being arranged at an angle, or a protrusion provided at the connection between the fourth sub-segment 1123 and the second connecting sub-segment 1122. This example of the present application does not impose any specific limitation on the molding method of the second abutting protrusion 1125. It is sufficient as long as the second abutting protrusion 1125 can abut against the first abutting groove 1115 during use of the bridge-type clamping assembly 100.
[0096] Based on the above, since the first abutting groove 1115 is formed by the cooperation between the second sub-segment 1113 and the first connecting sub-segment 1112, and the second abutting protrusion 1125 is formed by the cooperation between the fourth sub-segment 1123 and the second connecting sub-segment 1122, the cooperation between the second abutting protrusion 1125 and the first abutting groove 1115 can limit the position of the second connecting sub-segment 1122 relative to the first connecting sub-segment 1112, thereby reducing the possibility of displacement of the second connecting sub-segment 1122 relative to the first connecting sub-segment 1112. Since the second sub-segment 1113 and the first sub-connecting segment 1112 are part of the first clamping piece 111, and the fourth sub-segment 1123 and the second sub-connecting segment 1122 are part of the first clamping piece 112, the cooperation between the second abutting protrusion 1125 and the first abutting groove 1115 can limit the position of the first clamping piece 112 relative to the first clamping piece 111, reduce the possibility of displacement of the first clamping piece 112 relative to the first clamping piece 111, ensure the reliability of the cooperation between the first clamping piece 112 and the first clamping piece 111, and thereby reduce the possibility of a high temperature rise due to poor contact between the first clamping piece 111 and the first clamping piece 112.
[0097] Furthermore, based on the cooperation between the first abutting protrusion 1124 and the abutting section 1114, a second abutting protrusion 1125 is provided to cooperate with the first abutting groove 1115. Since the first abutting protrusion 1124 is provided at the end of the second sub-connecting section 1122 close to the third sub-connecting section 1121, and the second abutting protrusion 1125 is provided at the end of the second sub-connecting section 1122 close to the fourth sub-connecting section 1123, the cooperation between the first abutting protrusion 1124 and the abutting section 1114, and the cooperation between the second abutting protrusion 1125 and the first abutting groove 1115, can limit the position of the first sub-connecting section 1112 relative to the second sub-connecting section 1122 in different directions, further ensuring the connection reliability between the first clamping piece 111 and the first clip 112, and reducing the possibility of a high temperature rise caused by poor contact between the first clamping piece 111 and the first clip 112.
[0098] Based on the bridge-type clamping assembly 100 provided in the above example, a first limiting structure (not shown in the figure) is provided on the side of the first sub-connecting segment 1112 facing the second sub-connecting segment 1122, and a second limiting structure is provided on the side of the second sub-connecting segment 1122 facing the first sub-connecting segment 1112, and the second limiting structure cooperates with the first limiting structure.
[0099] The first limiting structure may be a limiting protrusion, and the second limiting structure may be a limiting groove. Alternatively, the first limiting structure may be a limiting groove, and the second limiting structure may be a limiting protrusion. The first limiting structure may be provided with one, two, or even more first limiting structures, and the number of second limiting structures may be equal to the number of first limiting structures, and the second limiting structures may correspond one to one with the first limiting structures. The first limiting structure and the second structure may also be other structures that cooperate and are capable of limiting the first sub-connecting segment 1112 and the second sub-connecting segment 1122. The examples of this application do not limit the specific implementation methods of the first limiting structure and the second limiting structure.
[0100] Based on the above, since the first limiting structure is provided on the first sub-connecting segment 1112 and the second limiting structure is provided on the second sub-connecting segment 1122, the cooperation between the first limiting structure and the second limiting structure can further ensure the cooperation reliability between the first sub-connecting segment 1112 and the second sub-connecting segment 1122, and further reduce the possibility of the second sub-connecting segment 1122 being displaced relative to the first sub-connecting segment 1112, thereby ensuring the connection reliability between the first clamping piece 111 and the first clamping piece 112, and reducing the possibility of a higher temperature rise due to poor contact between the first clamping piece 111 and the first clamping piece 112.
[0101] Based on the bridge type clamping assembly 100 provided in the above example, please refer to Figure 2 and Figure 3 The first clamping piece 111 may further include a limiting section 1116. The limiting section 1116 is provided at one end of the second sub-segment 1113 away from the first sub-connecting section 1112, and the limiting section 1116 cooperates with the end of the fourth sub-segment 1123 away from the second sub-connecting section 1122.
[0102] The limiting segment 1116 and the second sub-segment 1113 can be arranged at an angle to form a second abutment groove. During use of the bridge-type clamping assembly 100, the first clip 112 is deformed by force, specifically, the fourth sub-segment 1123 has a tendency to move away from the second sub-connecting segment 1122. Because the limiting segment 1116 cooperates with the first sub-connecting segment 1112 to form the second abutment groove, and the second abutment groove is arranged at the end of the second sub-segment 1113 facing away from the first sub-connecting segment 1112, the fourth sub-segment 1123 can abut against the groove wall of the second abutment groove, thereby limiting the displacement of the fourth sub-segment 1123 relative to the second sub-segment 1113 and ensuring the reliability of the connection between the fourth sub-segment 1123 and the second sub-segment 1113.
[0103] Based on the above, by setting the limiting segment 1116, the displacement amplitude of the fourth sub-segment 1123 relative to the second sub-segment 1113 in the direction away from the second connecting sub-segment 1122 can be reduced, thereby ensuring the connection reliability between the fourth sub-segment 1123 and the second sub-segment 1113.
[0104] Based on the bridge-type clamping assembly 100 provided in the above example, the first clamping piece 111 is in surface contact with the first busbar, and / or the first clamping piece 111 is in surface contact with the second busbar.
[0105] The contact method between the first clamping piece 111 and the first busbar is similar to the contact method between the first clamping piece 111 and the second busbar. Next, the contact method between the first clamping piece 111 and the first busbar and the contact method between the first clamping piece 111 and the second busbar will be described using the surface contact between the first clamping piece 111 and the first busbar as an example.
[0106] The contact surface between the first clamping piece 111 and the first busbar can be a plane or an arc surface. The first clamping piece 111 can directly contact the first busbar to cooperate with the second clamping piece to clamp the first busbar. The side of the first clamping piece 111 facing the first busbar can also be provided with a groove, and the side of the first busbar facing the first clamping piece can also be provided with a protrusion, or the side of the first clamping piece 111 facing the first busbar can also be provided with a protrusion, and the side of the first busbar facing the first clamping piece can also be provided with a groove, and the cooperation between the first busbar and the first clamping piece is achieved by the cooperation of the protrusion and the groove. Alternatively, the side of the first clamping piece facing the first busbar can be provided with an anti-slip structure. The cooperation method of the first clamping piece 111 and the first busbar in the example of this application is not specifically limited.
[0107] The resistance law states that the contact resistance between different conductors is inversely proportional to the contact area. Joule's law states that, given a constant current, the heat generated at the contact point of different conductors is inversely proportional to the contact area.
[0108] Compared to existing bridge-type clamping assemblies, in which the bridge-type clamping assembly contacts the first busbar and the second busbar, in this example, the first clamping piece 111 contacts the first busbar surface, increasing the contact area between the first clamping piece 111 and the first busbar, reducing the temperature rise generated at the contact point between the first clamping piece 111 and the first busbar, and thus reducing the temperature rise generated by the bridge-type clamping assembly 100 during use.
[0109] In the example of this application, the first clamping piece 111 contacts the second busbar surface, which increases the contact area between the first clamping piece 111 and the second busbar, reduces the temperature rise generated at the contact point between the first clamping piece 111 and the second busbar, and thus can reduce the temperature rise generated by the bridge-type clamping assembly 100 during use.
[0110] Based on the bridge type clamping assembly 100 provided in the above example, please refer to Figure 1The bridge clamping assembly 100 may further include a first connecting structure 150 and a second connecting structure 160. The first connecting structure 150 abuts against a side of the first clip set 110 facing away from the second clip set 120. The second connecting structure 160 abuts against a side of the second clip set 120 facing away from the first clip set 110.
[0111] The first connecting structure 150 may be a rod-shaped structure or a plate-shaped structure. This example of the application does not limit the specific implementation of the first connecting structure 150.
[0112] The second connection structure 160 can be a rod-shaped structure or a plate-shaped structure. The specific implementation of the second connection structure 160 and the first connection structure 150 can be the same or different, and this application example does not impose any specific restrictions on this.
[0113] Since the first connecting structure 150 abuts against the side of the first clip group 110 facing away from the second clip group 120, the first connecting structure 150 can apply a force to the first clip group 110, so that the first clip group 110 rotates with the contact point between the first clip group 110 and the first connecting structure 150 as the rotation center, and the opening size of the first clamp 130 and the second clamp 140 can be adjusted.
[0114] Because the first clip 112 in the first clip assembly 110 is located on the side of the first clamping piece 111 facing away from the second clip assembly 120, the first connecting structure 150 can abut against the first clip 112. During use of the bridge-type clamping assembly 100, the first clip 112 bears the primary abutting force applied by the first connecting structure 150. The abutting force acting on the first clip 112 can be transmitted to the first clamping piece 111, applying a force toward the first busbar on the first clamping piece 111, allowing the first clamping piece 111 to apply a clamping force to the first busbar and the second busbar, thereby clamping the first busbar and the second busbar together.
[0115] Because the second clips in the second clip set 120 are located on the side of the second clamping piece facing away from the first clip set 110, the second connecting structure 160 can abut against the second clips. During use of the bridge-type clamping assembly 100, the second clips bear the primary abutting force applied by the second connecting structure 160. The abutting force acting on the second clips can be transmitted to the second clamping piece, applying a force toward the second busbar, allowing the second clamping piece to apply a clamping force to the second busbar and the second busbar, thereby clamping the second busbar and the second busbar together.
[0116] Based on the above, the first connecting structure 150 is arranged on the side of the first clip group 110 away from the second clip group 120, and applies a force to the first clip group 110 toward the second clip group 120. The second connecting structure 160 is arranged on the side of the second clip group 120 away from the first clip group 110, and applies a force to the second clip group 120 toward the first clip group 110. Since the force applied to the first clip group 110 by the first connecting structure 150 is opposite to the force applied to the second clip group 120 by the second connecting structure 160, the force applied to the first busbar and the second busbar by the first clip group 110 is opposite to the force applied to the first busbar and the second busbar by the second clip group 120, so that the connection between the bridge-type clamping assembly 100 and the first busbar and the second busbar is more reliable.
[0117] Based on the bridge-type clamping assembly 100 provided in the above example, Figure 5 For a schematic diagram of the structure of a mounting bracket provided for this application example, please refer to Figure 1 and Figure 5 The bridge-type clamping assembly 100 may further include a mounting bracket 170 , and the mounting bracket 170 may cooperate with the first connecting structure 150 and the second connecting structure 160 at the same time.
[0118] The mounting bracket 170 may include a first side panel 171 and a second side panel 172 disposed opposite each other. Each of the first side panel 171 and the second side panel 172 may be provided with first and second mounting holes spaced apart from each other. The ends of the first connecting structure 150 may respectively engage with the first mounting holes provided on the first side panel 171 and the second side panel 172. The ends of the second connecting structure 160 may respectively engage with the second mounting holes provided on the first side panel 171 and the second side panel 172.
[0119] The first mounting hole may be a blind hole or a through hole, and the shape of the first mounting hole is adapted to the shape of the first connecting structure 150 .
[0120] The specific implementation method of the second mounting hole and the first mounting hole can be the same or different, and this application example does not impose any specific restrictions on this.
[0121] Based on the above, the mounting bracket 170 can provide a mounting carrier for the first connecting structure 150 and the second connecting structure 160, thereby making the cooperation between the first connecting structure 150 and the first clip group 110, and the second connecting structure 160 and the second clip group 120 more reliable, thereby improving the reliability of the bridge-type clamping assembly 100.
[0122] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
