Taking a drawer-type circuit breaker as an example, the drawer-type circuit breaker comprises a bridge-type clamping assembly, a drawer seat and a circuit breaker body, wherein the circuit breaker body can move relative to the drawer seat. The drawer seat is connected with the breaker body through a bridge type clamping assembly.

Based on the structure of current bridge type clamping assembly, drawer type circuit breaker's radiating effect is relatively poor, leads to the temperature rise in the drawer type circuit breaker higher, probably influences drawer type circuit breaker's performance.

In addition, compared with the prior art, the arrangement direction of the plurality of clamping pieces in the clamping piece group is perpendicular to the moving direction of the clamping opening, in the example of the application, the arrangement direction of at least one first clamping piece and the first clamping piece in the first clamping piece group is the same as the moving direction of the first clamping opening, therefore, the contact area between the first clamping piece and the first busbar in the example of the application is larger than the contact area between the clamping piece and the first busbar in the prior art, and the contact area between the first clamping piece and the contact area between two adjacent first clamping pieces in the example of the application are both larger than the contact area between two adjacent clamping pieces in the prior art. It is known based on the law of resistance that the contact resistance between different conductors is inversely proportional to the contact area. It is known based on joule's law that, at a certain current, the amount of heat generated at the contact of different conductors is inversely proportional to the contact area. Therefore, the temperature rise generated at the contact part of the bridge type clamping assembly and the first busbar, the contact part of the bridge type clamping assembly and the second busbar and the contact part of the first clamping piece and the first clamping piece is smaller.

The structure of the first clamping piece 111 may be identical to the structure of the first clamping piece 112, and the structure of the first clamping piece 111 may be identical to the structure of the first clamping piece 112. The structures of the plurality of first clamping pieces 112 may be identical, and the structures of the plurality of first clamping pieces 112 may also be different, which is not particularly limited in this embodiment of the present application, so long as the first clamping piece 111 and the second clamping piece are guaranteed to be matched, the first clamping opening 130 and the second clamping opening 140 can be formed, and the first busbar and the second busbar can be clamped at the same time, so as to realize the electrical connection between the first busbar, the second busbar and the bridge-type clamping assembly 100.

The connection between the adjacent first clamping pieces 112 is similar to the connection between the first clamping pieces 112 and the first clamping pieces 111, and only the first clamping pieces 112 and the first clamping pieces 111 are described below as an example.

The first clamping piece 111 and the first clamping piece 112 may be directly matched with each other, a spacer may be disposed between the first clamping piece 111 and the first clamping piece 112, one side of the spacer may be connected to the first clamping piece 111, and the other side of the spacer may be connected to the first clamping piece 112.

The specific implementation of the second clip set 120 is similar to the specific implementation of the first clip set 110. The number of second clips included in the second clip set 120 may be equal to or different from the number of first clips 112 in the first clip set 110, which is not particularly limited in the present embodiment. For the specific structure of the second clip set 120, reference may be made to the description related to the specific structure of the first clip set 110 described above.

The first clamping piece 111 and the second clamping piece cooperate to form a first clamping opening 130 and a second clamping opening 140.

In the case where the first busbar is clamped by the first clamping opening 130, the first clamping piece 111 and the second clamping piece may both be in contact with the first busbar surface, the first clamping piece 111 and the second clamping piece may both be in contact with the first busbar, one of the first clamping piece 111 and the second clamping piece may also be in contact with the first busbar surface, and the other one is in contact with the first busbar, which is not particularly limited in the present application.

The embodiment of the second clamping opening 140 for clamping the second busbar is similar to the embodiment of the first clamping opening 130 for clamping the first busbar, and please refer to the above description for clamping the first busbar by the first clamping opening 130.

According to the bridge-type clamping assembly 100 provided in the embodiment of the application, the first clamping piece set 110 and the second clamping piece set 120 may cooperate to form the first clamping opening 130 and the second clamping opening 140, and specifically, the first clamping piece 111 and the second clamping piece may cooperate to form the first clamping opening 130 and the second clamping opening 140. The first clamping port 130 may clamp the first busbar to electrically connect the bridge clamp assembly 100 with the first busbar. The second clamping port 140 may clamp the second busbar to electrically connect the bridge clamp assembly 100 with the second busbar. Because the first clamping opening and the second clamping opening 140 are both arranged on the bridge type clamping assembly 100, one of the first busbar and the second busbar can be connected with the circuit breaker body, and the other can be connected with the drawer seat, the bridge type clamping assembly 100 can be used for realizing the electric connection between the circuit breaker body and the drawer seat.

In this example, during the use of the bridge-type clamping assembly 100, the first clamping piece 112 may apply a force to the first clamping piece 111, and the second clamping piece may apply a force to the second clamping piece, so that the first clamping opening 130 is more reliably matched with the first busbar, the second clamping opening 140 is more reliably matched with the second busbar, the connection between the bridge-type clamping assembly 100 and the first busbar is reduced, and the possibility that the connection between the bridge-type clamping assembly 100 and the second busbar is unreliable due to contact and causes higher temperature rise is reduced.

In addition, compared to the prior art, the arrangement direction of the plurality of clips in the clip set is perpendicular to the moving direction of the clip opening, in the present example, the arrangement direction of at least one first clip 112 and the first clip 111 in the first clip set is the same as the moving direction of the first clip opening 130, so the contact area between the first clip 111 and the first busbar in the present example is larger than the contact area between the clip and the first busbar in the prior art, and the contact area between the first clip 111 and the first clip 112 in the present example, and the contact area between two adjacent first clips 112 are both larger than the contact area between two adjacent clips in the prior art. It is known based on the law of resistance that the contact resistance between different conductors is inversely proportional to the contact area. It is known based on joule's law that, at a certain current, the amount of heat generated at the contact of different conductors is inversely proportional to the contact area. Therefore, the temperature rise generated at the contact point of the bridge type clamping assembly 100 and the first busbar, the contact point of the bridge type clamping assembly 100 and the second busbar, and the contact point of the first clamping piece 111 and the first clamping piece 112 is smaller.

Based on the bridge-type clamping assembly 100 provided by the above example, the first clamping piece set 110 may include a first clamping section, a first connecting section and a second clamping section, where the first connecting section connects the first clamping section and the second clamping section. The second clamping set 120 may include a third clamping section, a second connecting section and a fourth clamping section, where 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 the first clamping opening 130, and the fourth clamping section cooperates with the second clamping section to form the second clamping opening 140.

The first clamping section and the first connecting section may be arranged at an angle, and an included 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 can be arranged at an angle, and an included angle formed by the second clamping section and the first connecting section can be an obtuse angle. The first clamping section and the second clamping section can be parallel, and the first clamping section and the second clamping section can also be arranged in an angle.

The third clamping section and the second connecting section can be arranged at an angle, and an included angle formed by the third clamping section and the second connecting section can be an obtuse angle. The fourth clamping section and the second connecting section can be arranged at an angle, and an included angle formed by the fourth clamping section and the second connecting section can be an obtuse angle. The third clamping section and the fourth clamping section can be parallel, and the third clamping section and the fourth clamping section can also be arranged in an angle.

The first connection section and the second connection section may be substantially parallel, specifically, an included angle between the first connection section and the second connection section is greater than or equal to 0 degrees and less than or equal to 10 degrees, which is not particularly limited by the present example.

The specific implementation manners of the first clamping section, the second clamping section, the third clamping section and the fourth clamping section are not limited in the embodiment of the present application, so long as the first clamping section and the third clamping section are matched to form the first clamping opening 130, the second clamping section and the fourth clamping section are matched to form the second clamping opening 140, and the second clamping opening 140 can clamp the second busbar on the basis of ensuring that the first clamping opening 130 clamps the first busbar.

The second clamping section and the fourth clamping section cooperate to form a second clamping opening 140 for clamping the second busbar. Thereby achieving electrical connection among the bridge clip assembly 100, the first busbar and the second busbar.

The first clamping set 110 is similar to the second clamping set 120, and the specific structure of the first clamping set 110 and the second clamping set 120 will be described below by taking the first clamping set 110 as an example.

Based on the bridge-type clamping assembly 100 provided by the above example, fig. 3 is a schematic structural diagram of a first clamping piece provided by the present application, and fig. 4 is a schematic structural diagram of a first clamping piece provided by the present application, referring to fig. 1 to 4, the first clamping piece 111 may include a first sub-section 1111, a first sub-connection section 1112 and a second sub-section 1113, and the first sub-connection section 1112 connects the first sub-section 1111 and the second sub-section 1113.

The first clip 112 may include a third sub-section 1121, a second sub-connection section 1122, and a fourth sub-section 1123, the second sub-connection section 1122 connecting the third sub-section 1121 with the fourth sub-section 1123, the third sub-section 1121 cooperating with the first sub-section 1111 to form a first clamping section, the second sub-connection section 1122 cooperating with the first sub-connection section 1112 to form a first connection section, and the fourth sub-section 1123 cooperating with the second sub-section 1113 to form a second clamping section.

The third sub-section 1121 may abut to the first sub-section 1111, the third sub-section 1121 may be connected to the first sub-section 1111 by other structures, and the first sub-section 1111 may be in surface contact with the third sub-section 1121.

The second sub-connection section 1122 may be abutted to the first sub-connection section 1112, the first sub-connection section 1112 may also be connected to the second sub-connection section 1122 by other structures, and the first sub-connection section 1112 is in surface contact with the second sub-connection section 1122.

The fourth sub-segment 1123 may abut the second sub-segment 1113, the second sub-segment 1113 may also be connected to the fourth sub-segment 1123 by other structures, and the second sub-segment 1113 may be in surface contact with the fourth sub-segment 1123.

Based on the above, in the use process of the bridge-type clamping assembly 100, the third sub-section 1121 can provide an acting force for the first sub-section 1111, so that the contact between the first sub-section 1111 and the first busbar is more reliable, and the possibility that the first sub-section 1111 and the first busbar generate higher temperature rise due to unreliable connection is further reduced, and the temperature rise generated in the use process of the bridge-type clamping assembly 100 is reduced. The fourth sub-segment 1123 may provide a force to the second sub-segment 1113, so that the contact between the second sub-segment 1113 and the second busbar is more reliable, thereby reducing the possibility of higher temperature rise of the second sub-segment 1113 and the second busbar due to unreliable connection, and reducing the temperature rise of the bridge-type clamping assembly 100 in use.

Based on the above example, referring to fig. 2 to 4, an abutment section 1114 is disposed between the first sub-section 1111 and the first sub-connection section 1112, and the abutment section 1114 is disposed at an angle to the first sub-connection section 1112. The third sub-segment 1121 cooperates with the second sub-connecting segment 1122 to form a first abutment protrusion 1124, the first abutment protrusion 1124 abutting against the abutment segment 1114.

The abutting section 1114 is a structure provided between the first subsection 1111 and the first sub-connection section 1112. The abutment section 1114 may be disposed at an angle to at least one of the first sub-section 1111 and the first sub-connection section 1112. The surface of the abutment section 1114 matching the first abutment protrusion 1124 may be a plane or may be provided with a groove, and the molding manner of the abutment section 1114 is not particularly limited in the present example.

The first abutment protrusion 1124 may be a protrusion formed by arranging the third sub-section 1121 and the second sub-connection section 1122 at an angle, or the first abutment protrusion 1124 may be a protrusion formed at a connection portion between the third sub-section 1121 and the second sub-connection section 1122, and the forming manner of the first abutment protrusion 1124 is not particularly limited in the present embodiment. So long as it is ensured that the first abutment protrusion 1124 is able to abut against the abutment section 1114 during use of the bridge clamp assembly 100.

Based on the above, since the abutting section 1114 is disposed between the first sub-section 1111 and the first sub-connection section 1112, and the first abutting protrusion 1124 is formed by the third sub-section 1121 and the second sub-connection section 1122 in cooperation. Thus, the cooperation of the first abutment protrusion 1124 with the abutment section 1114 can limit the position of the second sub-connection section 1122 relative to the first sub-connection section 1112, reducing the likelihood of displacement of the second sub-connection section 1122 relative to the first sub-connection section 1112.

Also, since the first subsection 1111 and the first sub-connection section 1112 are part of the first clamping piece 111, the third subsection 1121 and the second sub-connection section 1122 are part of the first clamping piece 112. Therefore, the position of the first clamping piece 112 relative to the first clamping piece 111 can be limited by the cooperation between the first abutting protrusion 1124 and the abutting section 1114, so that the possibility of displacement of the first clamping piece 112 relative to the first clamping piece 111 is reduced, the reliability of cooperation between the first clamping piece 112 and the first clamping piece 111 is ensured, and the possibility of higher temperature rise of the first clamping piece 111 and the first clamping piece 112 due to poor contact is further reduced.

Referring to fig. 2 to 4, referring to the bridge-type clamping assembly 100 provided by the above example, the first sub-connecting section 1112 and the second sub-section 1113 cooperate to form a first abutting groove 1115. The second sub-connection section 1122 cooperates with the fourth sub-section 1123 to form a second abutment projection 1125, the second abutment projection 1125 abutting the first abutment recess 1115.

The first abutting groove 1115 may be a groove formed by the second sub-segment 1113 and the first sub-connecting segment 1112 in an angle, and the first abutting groove 1115 may also be a groove formed at the connection position of the second sub-segment 1113 and the first sub-connecting segment 1112.

The second abutment protrusion 1125 may be a protrusion formed by arranging the fourth sub-section 1123 and the second sub-connection section 1122 at an angle, and the second abutment protrusion 1125 may be a protrusion arranged at a connection portion between the fourth sub-section 1123 and the second sub-connection section 1122, and the forming manner of the second abutment protrusion 1125 is not particularly limited in the present embodiment. So long as it is ensured that the second abutment protrusion 1125 can abut the first abutment recess 1115 during use of the bridge clip assembly 100.

Based on the above, since the first abutment recess 1115 is formed by the second sub-section 1113 mated with the first sub-connection section 1112, and the second abutment projection 1125 is formed by the fourth sub-section 1123 mated with the second sub-connection section 1122. Thus, the second abutment protrusion 1125 cooperates with the first abutment recess 1115 to limit the position of the second sub-connection segment 1122 relative to the first sub-connection segment 1112, reducing the likelihood of displacement of the second sub-connection segment 1122 relative to the first sub-connection segment 1112. Because 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 position of the first clamping piece 112 relative to the first clamping piece 111 can be limited by the cooperation between the second abutting protrusion 1125 and the first abutting groove 1115, the possibility of displacement of the first clamping piece 112 relative to the first clamping piece 111 is reduced, the reliability of the cooperation between the first clamping piece 112 and the first clamping piece 111 is ensured, and the possibility of high temperature rise of the first clamping piece 111 and the first clamping piece 112 due to poor contact is further reduced.

In addition, on the basis of the engagement of the first abutment protrusion 1124 with the abutment section 1114, a second abutment protrusion 1125 is provided to engage with the first abutment recess 1115, and since the first abutment protrusion 1124 is provided at an end of the second sub-connection section 1122 near the third sub-section 1121, the second abutment protrusion 1125 is provided at an end of the second sub-connection section 1122 near the fourth sub-section 1123. Therefore, the first abutting protrusion 1124 and the abutting section 1114 and the second abutting protrusion 1125 and the first abutting groove 1115 cooperate to limit the position of the first sub-connecting section 1112 relative to the second sub-connecting section 1122 along different directions, so as to further ensure the connection reliability of the first clamping piece 111 and the first clamping piece 112, and reduce the possibility of higher temperature rise of the first clamping piece 111 and the first clamping piece 112 due to poor contact.

Based on the bridge-type clamping assembly 100 provided in the above example, a first limiting structure (not shown in the figure) is disposed on a side of the first sub-connecting section 1112 facing the second sub-connecting section 1122, and a second limiting structure is disposed on a side of the second sub-connecting section 1122 facing the first sub-connecting section 1112, where the second limiting structure is matched with the first limiting structure.

The first limit structure may be a limit protrusion, and the second limit structure may be a limit groove. Or the first limit structure may be a limit groove, and the second limit structure may be a limit protrusion. The first limit structure can be provided with one, two or even more, the number of the second limit structures is equal to that of the first limit structures, and the second limit structures are in one-to-one correspondence with the first limit structures. The first limiting structure and the second limiting structure may be other structures that cooperate and can limit the first sub-connection section 1112 and the second sub-connection section 1122, and specific implementation manners of the first limiting structure and the second limiting structure are not limited in the present disclosure.

Based on the above, since the first limiting structure is disposed on the first sub-connecting section 1112 and the second limiting structure is disposed on the second sub-connecting section 1122, the reliability of the cooperation between the first sub-connecting section 1112 and the second sub-connecting section 1122 can be further ensured by the cooperation between the first limiting structure and the second limiting structure, the possibility of displacement of the second sub-connecting section 1122 relative to the first sub-connecting section 1112 is further reduced, the connection reliability of the first clamping piece 111 and the first clamping piece 112 is further ensured, and the possibility of higher temperature rise of the first clamping piece 111 and the first clamping piece 112 due to poor contact is reduced.

Referring to fig. 2 and 3, the first clamping piece 111 may further include a limiting section 1116 based on the bridge-type clamping assembly 100 provided in the above example. The limiting segment 1116 is disposed at an end of the second sub-segment 1113 remote from the first sub-connecting segment 1112, and the limiting segment 1116 is matched with an end of the fourth sub-segment 1123 remote from the second sub-connecting segment 1122.

The stop segment 1116 and the second sub-segment 1113 may be disposed at an angle to form a second abutment recess. In the use process of the bridge-type clamping assembly 100, the first clamping piece 112 is stressed to deform, specifically, the fourth sub-section 1123 has a movement trend towards and away from the second sub-connecting section 1122, because the limiting section 1116 and the first sub-connecting section 1112 cooperate to form a second abutting groove, and the second abutting groove is formed at one end of the second sub-section 1113, which is away from the first sub-connecting section 1112, the fourth sub-section 1123 can be abutted to the groove wall of the second abutting groove, so that the displacement amplitude of the fourth sub-section 1123 relative to the second sub-section 1113 is limited, and the connection reliability of the fourth sub-section 1123 and the second sub-section 1113 is ensured.

Based on the above, by providing the limiting section 1116, the displacement amplitude of the fourth sub-section 1123 relative to the second sub-section 1113 along the direction away from the second sub-connection section 1122 can be reduced, so as to ensure the connection reliability of the fourth sub-section 1123 and the second sub-section 1113.

Based on the bridge clip assembly 100 provided by the above example, the first clip tab 111 is in surface contact with the first busbar. And/or the first clamping piece 111 is in surface contact with the second busbar.

The contact manner of the first clamping piece 111 and the first busbar is similar to the contact manner of the first clamping piece 111 and the second busbar. Next, a contact manner of the first clamping piece 111 with the first busbar and a contact manner of the first clamping piece 111 with the second busbar will be described only by taking an example of surface contact of the first clamping piece 111 with the first busbar.

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 may directly contact the first busbar to clamp the first busbar in cooperation with the second clamping piece. The first clamping piece 111 can also be provided with the recess towards one side of first female row, and first female row can also be equipped with the arch towards one side of first clamping piece, or first clamping piece 111 can also be equipped with the arch towards one side of first female row, and first female row can also be equipped with the recess towards one side of first clamping piece, realizes the cooperation of first female row and first clamping piece through the cooperation of arch and recess. Or the side of the first clamping piece facing the first busbar can be provided with an anti-slip structure. The manner in which the first clamping piece 111 is mated with the first busbar is not particularly limited.

It is known based on the law of resistance that the contact resistance between different conductors is inversely proportional to the contact area. It is known based on joule's law that, at a certain current, the amount of heat generated at the contact of different conductors is inversely proportional to the contact area.

Compared with the prior bridge type clamping assembly, the bridge type clamping assembly is contacted with the first busbar, and the bridge type clamping assembly is contacted with the second busbar. In the example of the present application, the first clamping piece 111 contacts with the first busbar surface, so that the contact area between the first clamping piece 111 and the first busbar is increased, and the temperature rise generated at the contact position between the first clamping piece 111 and the first busbar is reduced, so that the temperature rise generated in the use process of the bridge type clamping assembly 100 can be reduced.

In the example of the present application, the first clamping piece 111 contacts with the second busbar surface, so that the contact area of the first clamping piece 111 and the second busbar is increased, and the temperature rise generated at the contact position of the first clamping piece 111 and the second busbar is reduced, so that the temperature rise generated in the use process of the bridge type clamping assembly 100 can be reduced.

Referring to fig. 1, referring to the bridge-type clamping assembly 100 provided by the above example, the bridge-type clamping assembly 100 may further include a first connection structure 150 and a second connection structure 160. The first connection structure 150 is abutted to a side of the first clip set 110 facing away from the second clip set 120. The second connection structure 160 abuts against a side of the second clip set 120 facing away from the first clip set 110.

The first connection structure 150 may have a rod-shaped structure, and the first connection structure 150 may have a plate-shaped structure, and the specific implementation of the first connection structure 150 is not limited by the present example.

The second connection structure 160 may have a rod-shaped structure, and the second connection structure 160 may have a plate-shaped structure. The specific implementation of the second connection structure 160 and the first connection structure 150 may be the same, and may be different, which is not particularly limited by the present example.

Since the first connection structure 150 is abutted to a side of the first clip set 110 facing away from the second clip set 120, the first connection structure 150 can apply a force to the first clip set 110, so that the first clip set 110 rotates with a contact portion of the first clip set 110 and the first connection structure 150 as a rotation center, and the opening sizes of the first clip opening 130 and the second clip opening 140 can be adjusted.

Because the first clamping piece 112 in the first clamping piece set 110 is disposed on a side of the first clamping piece 111 facing away from the second clamping piece set 120, the first connecting structure 150 can abut against the first clamping piece 112, and the first clamping piece 112 bears a main abutment force applied by the first connecting structure 150 during use of the bridge-type clamping assembly 100. The abutment force acting on the first clamping piece 112 can be transferred to the first clamping piece 111, and a force towards the first busbar is applied to the first clamping piece 111, so that the first clamping piece 111 can apply clamping force to the first busbar and the second busbar to clamp the first busbar and the second busbar.

Because the second clip in the second clip set 120 is disposed on a side of the second clip facing away from the first clip set 110, the second connection structure 160 can abut against the second clip, and the second clip bears a main abutment force applied by the second connection structure 160 during use of the bridge clip assembly 100. The abutment force acting on the second clamping piece can be transferred to the second clamping piece, and the second clamping piece is applied with a force towards the second busbar, so that the second clamping piece can apply clamping force to the second busbar and the second busbar to clamp the second busbar and the second busbar.

Based on the above, the first connecting structure 150 is disposed on the side of the first clip group 110 facing away from the second clip group 120, so as to apply a force to the first clip group 110 towards the second clip group 120, the second connecting structure 160 is disposed on the side of the second clip group 120 facing away from the first clip group 110, and apply a force to the second clip group 120 towards the first clip group 110, and since the direction of the force applied by the first connecting structure 150 to the first clip group 110 is opposite to the direction of the force applied by the second connecting structure 160 to the second clip group 120, the direction of the force applied by the first clip group 110 to the first busbar and the second busbar is opposite to the direction of the force applied by the second clip group 120 to the first busbar and the second busbar, so that the connection between the bridge clamping assembly 100 and the first busbar and the second busbar is more reliable.
