Description

Technical Field

[0001] This invention relates to the field of cast-in-place busbar connection technology, and particularly to a connector used in cast-in-place applications. Background Technology

[0002] As a crucial conductive or transmission component, the stability and reliability of the connections between cast-in-place busbars are vital to the operation of the overall system. Traditional connection methods have numerous shortcomings and cannot meet the increasingly demanding engineering requirements. Therefore, a specially designed connector is needed to optimize the connections between cast-in-place busbars. Specifically: 1. Traditional connection methods cannot ensure the stability of the connections between cast-in-place busbars, and loosening is prone to occur after long-term use or under external forces, affecting conductivity or transmission efficiency; 2. During the connection process, torque control may not be precise enough, resulting in bolts and other connectors not achieving optimal tightening, or damage to connectors due to excessive torque; 3. The positioning of the busbar connection position is not precise enough, leading to deviations during connection, affecting connection quality and the performance of the overall system; 4. When inserting the connector into the cast-in-place busbar, the lack of a clear limiting mechanism leads to inaccurate insertion depth or position, affecting the connection effect. Summary of the Invention

[0003] The purpose of this invention is to provide a connector for casting to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a connector for casting, comprising an aluminum profile pressure plate, a connector middle plate disposed between the aluminum profile pressure plates, a connector side plate disposed between one side of the connector middle plate and the aluminum profile pressure plate, a nut groove disposed on one side of the outer wall of the aluminum profile pressure plate, a first rounded corner disposed on the aluminum profile pressure plate, and a second rounded corner disposed on one side of the outer wall of the nut groove.

[0005] As a further technical solution of the present invention, a through hole is provided in the nut groove, and a bolt is sleeved in the through hole.

[0006] As a further technical solution of the present invention, the two outer walls of the connector middle plate are provided with first positioning grooves, and the bolts are sleeved in the first positioning grooves. The two ends of the connector middle plate are provided with third rounded corners and first aircraft heads, and the two outer walls of the connector middle plate are provided with first positioning protrusions.

[0007] As a further technical solution of the present invention, the connector side plate has a second positioning groove on both outer walls and the bolt is sleeved in the second positioning groove. The connector side plate has a fourth rounded corner and a second aircraft head at both ends and a second positioning protrusion on one outer wall.

[0008] As a further technical solution of the present invention, one end of the bolt is threaded with a square nut, and the square nut is engaged in the nut slot and is tightly attached to the aluminum profile pressure plate.

[0009] As a further technical solution of the present invention, a large washer is fitted onto the bolt.

[0010] As a further technical solution of the present invention, the bolt is provided with a red marking plate indicating breakage.

[0011] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention designs a connector for casting. The pressure plate adopts a design that fits a square nut, which is conducive to breaking the torque bolt and ensuring the stability and reliability of the connection. At the same time, the rounded corner design not only makes the appearance more beautiful, but also acts as a reinforcing rib, enhancing the overall strength of the connector. The middle plate adopts a groove and convex strip design, which can accurately position the busbar connection position, ensuring that each connection is accurate and error-free, improving the accuracy and efficiency of the connection. By setting the aircraft head structure, the insertion depth and position of the cast busbar are effectively limited, avoiding connection problems caused by improper insertion, improving the accuracy and stability of the connection. The rounded corner design allows the connector to easily transition under force, reducing stress concentration and extending the service life of the connector. It also makes the connector smoother during installation and use, improving the user experience. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see the appendix Figure 1 - Appendix Figure 6This invention provides an embodiment of a connector for casting, comprising an aluminum profile pressure plate 1, a connector middle plate 2 disposed between the aluminum profile pressure plates 1, a connector side plate 3 disposed between one side of the connector middle plate 2 and the aluminum profile pressure plate 1, a nut groove 11 disposed on one side of the outer wall of the aluminum profile pressure plate 1, a first rounded corner 13 disposed on the aluminum profile pressure plate 1, and a second rounded corner 14 disposed on one side of the outer wall of the nut groove 11. The first rounded corner 13 and the second rounded corner 14 enable the nut groove 11 to function as a reinforcing rib. The rounded corner structure effectively disperses stress and reduces stress concentration. The stress is evenly distributed, avoiding structural failure caused by excessive local stress and improving the ability of the nut slot 11 to resist bending and deformation; a through hole 12 is opened in the nut slot 11, and a bolt 4 is sleeved in the through hole 12; a first positioning groove 21 is opened on both sides of the outer wall of the connector middle plate 2, and the bolt 4 is sleeved in the first positioning groove 21; the two ends of the connector middle plate 2 are provided with a third rounded corner 22 and a first aircraft head 23; a first positioning protrusion 24 is provided on both sides of the outer wall of the connector middle plate 2; a second positioning groove 31 is opened on both sides of the outer wall of the connector side plate 3, and the bolt 4 is sleeved in the first positioning groove 21. Bolt 4 is fitted into the second positioning groove 31. The connector side plate 3 has fourth rounded corners 32 and second aircraft heads 33 at both ends. A second positioning protrusion 34 is provided on one outer wall of the connector side plate 3. The busbar smoothly transitions through the third rounded corner 22 or the fourth rounded corner 32 and is limited by the first aircraft head 23 or the second aircraft head 33, controlling the insertion depth of the cast busbar. Simultaneously, the groove formed by the protrusion of the aircraft head, in conjunction with the corresponding first positioning protrusion 24 or second positioning protrusion 34, precisely positions the connection point of the cast busbar. One end of bolt 4 is threaded with a square... Nut 7, a square nut 7, is engaged in the nut slot 11 and is tightly attached to the aluminum profile pressure plate 1. The square nut 7 is anti-rotation and limited by the nut slot 11 on both sides and is attached to the aluminum profile pressure plate 1 to facilitate the breaking of bolt 4. A large washer 5 is fitted on bolt 4 to prevent loosening. A red break mark 6 is provided on bolt 4. During the tightening of bolt 4, when the torque reaches the set value, the red break mark 6 will be broken, thus visually indicating that the tightening is completed. This helps to ensure that bolt 4 reaches the same tightening torque and improves the stability and reliability of the connection.

[0017] Working Principle: This invention consists of an aluminum profile pressure plate 1, a connector middle plate 2, and a connector side plate 3. Aluminum profile pressure plates 1 are located on both sides, and the connector middle plate 2 is located in the middle. A connector side plate 3 is located between the connector middle plate 2 and the aluminum profile pressure plate 1 on one side. A bolt 4 is passed through the through hole 12 on the aluminum profile pressure plate 1, and the broken red-marked piece 6 and large washer 5 are inserted. The bolt 4 is then inserted into the second positioning groove 31 of the connector side plate 3 and the first positioning groove 21 of the connector middle plate 2, and passes through the through hole 12 on the aluminum profile pressure plate 1 on the other side, ensuring the bolt 4 is vertical and stable. A square nut 7 is inserted into the nut slot 11, and one end of the bolt 4 is screwed into the square nut 7. The square nut 7 is stopped and limited by the nut slot 11 on both sides. The bolt 4 is tightened using a suitable tool to pre-tighten the connector. The cast busbar is then inserted into the connector, passing through the third rounded corner 22 or the fourth rounded corner 3. 2. A smooth transition is achieved, and the insertion depth of the cast busbar is controlled by limiting the position through the first aircraft head 23 or the second aircraft head 33. At the same time, the groove formed by the protrusion of the aircraft head, in conjunction with the first positioning protrusion 24 or the second positioning protrusion 34 at the corresponding position, accurately positions the connection position of the cast busbar. The bolt 4 is tightened until the required tightening torque is reached. During the tightening of the bolt 4, when the torque reaches the set value, the red cutter 6 will be broken, thus visually indicating that the tightening is completed. This helps to ensure that the bolt 4 reaches the same tightening torque, improving the stability and reliability of the connection. The first fillet 13 and the second fillet 14 make the nut groove 11 act as a reinforcing rib. The fillet structure effectively disperses the stress, reduces stress concentration, and makes the stress evenly distributed, avoiding structural failure caused by excessive local stress, and improving the ability of the nut groove 11 to resist bending and deformation.
