Technical Field

[0001] This application relates to the field of connector technology, and in particular to a connector for an integrated quick-lock copper busbar connection. Background Technology

[0002] Existing copper busbar connection locking structures mainly use screw connections, which require tools to connect via screws and nuts. Screw connections cannot achieve quick-lock functionality, are cumbersome to operate, and are inconvenient to maintain. Furthermore, existing quick-lock connectors have separate current transmission and quick-lock mechanisms, resulting in excessively high costs and an inability to simultaneously meet the requirements of high current transmission and low cost.

[0003] Therefore, it is necessary to design an integrated quick-lock copper busbar connector to solve the above problems. Utility Model Content

[0004] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides an integrated quick-lock copper busbar connector, which effectively solves the problems that existing connectors either lack a quick-lock structure and cannot achieve quick connection, or the current transmission and quick-lock structure are separate structures, resulting in high costs and the inability to simultaneously meet the requirements of high current transmission and low cost.

[0005] According to the present invention, an integrated quick-lock copper busbar connector is provided at one end of the copper busbar that mates with the connector. The integrated quick-lock copper busbar connector includes a main body, which is an integral sheet metal component. The end of the main body in a first direction is a connecting end, which is used for mates with the copper busbar. A movable spring is provided on the side of the connecting end. The end of the main body in a second direction is a locking end, which has a locking space for accommodating the movable spring. When the copper busbar is connected to the connector, the movable spring can be locked in the limiting part.

[0007] Preferably, the bending portion is located in the middle of the integrated sheet metal component, and the mating portion is located at both ends of the integrated sheet metal component. When the integrated sheet metal component is bent by the bending portion to form a double-layer structure, the two mating portions located at both ends of the integrated sheet metal component are mated together.

[0008] Preferably, the docking portion is provided with alternating protruding limiting blocks and limiting grooves.

[0009] Preferably, the port of the connecting end is provided with a thickness limiting part, the thickness limiting part including a limiting strip with bends, the limiting strip being disposed on the upper and lower sides of the port of the connecting end.

[0010] Preferably, a recess is provided in the middle of the upper and lower surfaces of the main body, and the distance between the recess on the upper surface and the recess on the lower surface corresponds to the distance between the limiting strip on the upper side and the limiting strip on the lower side.

[0011] Preferably, a contact portion is provided between the recess and the connecting end, and the contact portion includes a plurality of connection points connected to the copper busbar.

[0012] Preferably, the number of contact points is multiple.

[0013] Preferably, in the mating direction, the two contact portions are back-to-back with each other to mate with the two copper busbars, and in the height direction, the two contact portions face each other to abut against the upper and lower surfaces of one copper busbar.

[0029] According to the present invention, a connector for an integrated quick-lock copper busbar connection is provided, such as... Figures 1 to 6 As shown, the integrated quick-lock copper busbar connector is used for docking the copper busbar body 6. The integrated quick-lock copper busbar connector includes a main body 1 formed by an integrated sheet metal component.

[0030] In the following description, reference will be made to Figures 1 to 6 This section describes the detailed structure of the main body 1, formed by the integral sheet metal component of the integrated quick-lock copper busbar connector. Furthermore, the description of the embodiment also involves a first direction S1, a second direction S2, a mating direction, and a height direction. The first direction S1 can be understood as the direction from left to right (3 in the figure), or as the direction from one end to the other in the length direction of the integrated quick-lock copper busbar connector. The second direction S2 can be understood as the direction from bottom to top (3 in the figure), or as the direction from one end to the other in the width direction of the integrated quick-lock copper busbar connector. The mating direction can be understood as... Figure 1 In the middle, the direction of the copper busbar body 6 facing the integrated quick-lock copper busbar connector, the height direction can be understood as... Figure 4The direction is from bottom to top. In addition, the copper busbar body 6 is also a commonly used component in the prior art. The end of the copper busbar body 6 facing the connector is provided with a limiting part 601. The width of the end where the limiting part 601 is located is greater than the width of the end of the copper busbar body 6 away from the connector, so that the copper busbar body 6 can be engaged with the connector.

[0031] like Figure 1 As shown in the embodiment, the integrated quick-lock copper busbar connector includes a main body 1, which is an integral sheet metal component. The connector is a single-piece molded component formed by bending the sheet metal, allowing the connector to achieve docking of the copper busbar body 6 with only one part. This simplifies the connection process and integrates the current transmission structure and quick-lock structure into a single unit, reducing costs.

[0032] Furthermore, such as Figure 3 As shown in the embodiment, the end of the main body 1 in the first direction S1 is a connecting end 2. The connecting end 2 is used for docking with the copper busbar body 6. There are two connecting ends 2, which can achieve... Figure 1 The copper busbars 6 on the left and right sides are connected.

[0033] Furthermore, a movable spring 3 is provided on the side of the connecting end 2, and the end of the main body 1 in the second direction S2 is a fastening end 4. The fastening end 4 has a locking space 5 for accommodating the movable spring 3. When the copper busbar body 6 is connected to the connector, the movable spring 3 can be locked in the limiting part 601. Figure 1 As shown, the copper busbar body 6 approaches the connecting end 2 along the mating direction and is pushed into the connecting end 2. The end of the copper busbar body 6 near the connector pushes open the movable spring 3 until it reaches the position of the recessed part 103 described below. Under the action of its own elastic force, the movable spring 3 tightens and abuts against the limiting part 601, realizing the quick-lock function. When separating, it is necessary to use a tool to first open the movable spring 3 on both sides of the copper busbar body 6, and then remove the copper busbar body 6.

[0034] This integrated quick-lock copper busbar connector features a main body 1 formed from a single sheet metal component, allowing the copper busbar body 6 to be quickly locked onto the connector for a simple quick-lock operation. The main body 1, formed by bending a single sheet metal component, enables the connector to mate the copper busbar body 6 with a single part. This simplifies the connection process and integrates the current transmission structure with the quick-lock structure, reducing costs. The movable spring 3 at the connection end 2 engages with the limiting part 601 of the copper busbar body 6, allowing the copper busbar body 6 to be locked onto the connector without tools. The reliable connection can handle current transmission from 400A to 1000A, simplifying the connection process, reducing operational difficulty, and facilitating future maintenance.

[0035] Preferably, such as Figure 2 As shown, in this embodiment, the integrated sheet metal component may include a bending portion 101 and a mating portion 102. The integrated sheet metal component is bent by the bending portion 101, and the two ends of the integrated sheet metal component are mated by the mating portion 102 to form a double-layered main body 1. The gap in the middle of the double-layered structure is used for the insertion of the copper busbar body 6.

[0036] Preferably, such as Figure 2 As shown, in this embodiment, the bending portion 101 is located in the middle of the integral sheet metal component, and the mating portions 102 are located at both ends of the integral sheet metal component. When the integral sheet metal component is bent by the bending portion 101 to form a double-layer structure, the two mating portions 102 located at both ends of the integral sheet metal component are mated. The integral sheet metal component is a plate-shaped structure that is approximately rectangular during production. The bending portion 101 is provided in the middle of the plate-shaped structure. The two ends (matting portions 102) of the integral sheet metal component are brought closer to each other by the bending of the bending portion 101 and are mated by the two mating portions 102.

[0037] Preferably, such as Figure 2 and Figure 4 As shown, in this embodiment, the docking portion 102 is provided with alternating raised limiting blocks 1021 and limiting grooves 1022. The side of the docking portion 102 is formed into a wave-shaped structure. The wave-shaped structure can realize the overall closure of the plate, ensure that the part is a cuboid, facilitate the molding of the main body 1, and the overlap of the wave-shaped structure can ensure the mechanical strength of the connector.

[0038] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the port of the connecting end 2 is provided with a thickness limiting part, which is used to limit the thickness of the copper busbar body 6 to prevent mechanical damage caused by mismatched copper busbar errors. The thickness limiting part may include a bent limiting strip 201, which is provided on the upper and lower sides of the port of the connecting end 2. By using the bent limiting strip 201, the port of the connecting end 2 is changed from a plane to a port with a bending angle, which can increase the mechanical strength at the port and at the same time limit the insertion of the copper busbar body 6, ensuring that the movement of the copper busbar body 6 will not damage the connection contact point 1041 under vibration and impact.

[0039] Preferably, such as Figures 1 to 5As shown, in this embodiment, a recess 103 is provided in the middle of the upper and lower surfaces of the main body 1. The distance between the recess 103 on the upper surface and the recess 103 on the lower surface corresponds to the distance between the upper and lower limiting strips 201. The recess 103 increases the mechanical strength of the main body 1 and, together with the limiting strips 201, limits the height of the copper busbar body 6, ensuring that the movement of the copper busbar body 6 will not damage the contact point 1041 described below under vibration and impact conditions.

[0040] Preferably, such as Figures 1 to 4 and Figure 6 As shown, in this embodiment, a contact portion 104 is provided between the recessed portion 103 and the connecting end 2. The contact portion 104 may include a plurality of connection contact points 1041 connected to the copper busbar body 6. After the copper busbar body 6 is inserted into the connector from the connecting end 2, it contacts the contact portion 104 and establishes an electrical connection.

[0041] Preferably, such as Figures 1 to 4 and Figure 6 As shown, in this embodiment, there are multiple contact portions 104. By providing multiple contact portions 104, full contact with the copper busbar body 6 can be achieved, ensuring excellent current transmission and enabling high-power current transmission.

[0042] Preferably, such as Figures 1 to 4 and Figure 6 As shown, in the embodiment, in the docking direction, the two contact portions 104 are back to back to dock with the two copper busbar bodies 6, and in the height direction, the two contact portions 104 face each other to abut against the upper and lower surfaces of one copper busbar body 6.

[0043] Preferably, in this embodiment, the thickness of the one-piece sheet metal component is 1.5-2mm. The one-piece sheet metal component is formed by stamping a copper plate with a thickness of 1.5-2mm, and the left and right sides are symmetrically structured for easy assembly.

[0044] The assembly process of the connector for the integrated quick-lock copper busbar connection and the copper busbar body 6 is as follows: Figure 1 As shown, the copper busbar body 6 approaches the connecting end 2 along the mating direction and is pushed into the connecting end 2. The limiting strip 201 of the connecting end 2 can restrict the specifications of the copper busbar body 6 and prevent mis-insertion. The end of the copper busbar body 6 near the connector pushes open the movable spring 3 until it reaches the position of the recess 103. The movable spring 3 tightens under its own elastic force and abuts against the limiting part 601 to realize the quick-lock function. The copper busbar body 6 abuts against the multiple connecting contact points 1041 of the contact part 104. When separating, it is necessary to use a tool to first open the movable springs 3 on both sides of the copper busbar body 6, and then remove the copper busbar body 6.

[0045] This integrated quick-lock copper busbar connector features a main body formed from a single sheet metal component, allowing the copper busbar to be quickly locked onto the connector for a simple, quick-lock operation. The main body, formed by bending a single sheet metal component, enables the connector to mate the copper busbar with a single part. This simplifies the connection process and integrates the current transmission structure with the quick-lock mechanism, reducing costs. The movable spring at the connection end engages with the limiting part of the copper busbar, allowing for tool-free locking between the copper busbar and the connector. The reliable connection supports current transmission from 400A to 1000A, simplifying the connection process, reducing operational difficulty, and facilitating future maintenance.
