Technical Field

[0001] The utility model relates to the technical field of copper bar stamping parts, in particular to an elastic copper bar stamping part. Background Art

[0002] Copper busbar stampings are important components for current transmission in the electronic and electrical fields. They are usually made of highly conductive copper materials. In the automobile manufacturing process, a large number of stampings are needed as connectors, and copper stampings are needed to complete the connection with the external power supply.

[0003] The prior art discloses a copper busbar stamping for new energy vehicle motors. This device is provided with T-shaped fixings and round-shaped fixings on both sides of the stamping body respectively. Through the T-shaped fixings and round-shaped fixings, the plastic wrapped around the copper busbar stamping is firmly combined with the stamping body.

[0004] However, this component still has some defects. Since the copper busbar stamping in this device is a whole piece structure, in the overall copper busbar design, in order to ensure good conductivity, higher purity copper materials are usually used, and higher purity copper often has lower hardness and elasticity.

[0005] Therefore, it is necessary to provide a copper bar stamping with elasticity to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an elastic copper busbar stamping part that can be fixed by extruding the connecting parts at both ends to the stamping part body. The extrusion-fixed connection method allows a certain displacement and deformation at the connection point, which can provide a certain degree of elasticity for the entire structure.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A copper busbar stamping part with elasticity comprises: a stamping part body and a connecting part, wherein the connecting part is installed in combination, and the two ends are respectively plug-fitted and fixedly installed on the two ends of the stamping part body, the stamping part body is also sleeved with an insulating sleeve, and the two ends of the stamping part body are provided with a accommodating cavity, the accommodating cavity is provided with a pressing cavity, the connecting part is plugged into the accommodating cavity, the connecting part comprises a connecting block installed in the accommodating cavity, the connecting block is made of conductive material, one end of the connecting block is respectively welded to a first connecting plate and a second connecting plate, the ends of the first connecting plate and the second connecting plate are both provided with positioning plates, and the positioning plates are welded to the end sides of the first connecting plate and the second connecting plate.

[0009] Preferably, the first connecting plate and the second connecting plate are both provided with a weight-reducing groove cavity, and the weight-reducing cavity connects the first connecting plate and the second connecting plate.

[0010] Preferably, the connection block is engaged with the accommodating cavity provided in the stamping part body, and is fixedly connected to the stamping part body by extrusion through the pressing cavities provided on the accommodating cavities at both ends.

[0011] Preferably, a coating film is disposed on the periphery of the first connecting plate and the second connecting plate, and the coating film wraps the first connecting plate and the second connecting plate.

[0012] Preferably, a gripping piece is also sleeved on the stamping part body, and the cavity provided by the gripping piece wraps the insulating sleeve therein, and the two are tightly against each other.

[0013] Preferably, the gripping member comprises a first clamping plate and a second clamping plate, an inserting block is provided at the end of the first clamping plate, and the inserting block is adapted to be engaged with a positioning notch provided on the second clamping plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) The utility model cooperates with the provided stamping body and the connecting piece. In actual use, the first connecting plate and the second connecting plate are inserted into the accommodating cavity provided in the stamping body through the connecting block, and then the extrusion type fixed connection method is used. Compared with the traditional welding and overall design, the extrusion type fixed connection method allows a certain displacement and deformation at the connection point, which can provide a certain degree of elasticity for the entire structure. The elastic copper bar stamping can adapt to the expansion or contraction of the material caused by temperature changes, reducing the risk of structural damage caused by thermal expansion;

[0016] (2) The utility model provides a weight-reducing cavity on the first connecting plate and the second connecting plate. The weight-reducing cavity can reduce the overall weight of the copper busbar, reduce the consumption of copper materials, and thus reduce costs. Meanwhile, for a power system that requires a large number of copper busbars, reducing the weight of the copper busbar can reduce the load of the entire system and simplify the installation and support structure.

[0017] (3) The utility model can simplify the assembly process of the copper busbar and the connecting block by inserting and extruding the connecting block into the accommodating cavity provided in the stamping body, because the connecting block only needs to be embedded in the accommodating cavity and fixed by extrusion, without the need for additional welding or complex fasteners. At the same time, the contact area between the connecting block and the stamping is increased by extrusion fixation, thereby providing a more uniform and stable pressure distribution, and enhancing the reliability and conductivity of the connection.

In actual use, the staff inserts the connecting block 202 provided at the end of the first connecting plate 201 into the accommodating cavity 101 provided on the stamping body 100. Similarly, the connecting block 202 provided at the end of the second connecting plate 203 is inserted into the accommodating cavity 101, and then the insulating sleeve 103 is sleeved on the middle end of the stamping body 100. Then, through the extrusion molding device, the extrusion molding device is an existing pressing technology, through the pressing cavity 102 provided at both ends of the stamping body 100, the pressing cavity 102 is moved downward until the pressing cavity 102 is tightly connected and fixed with the connecting block 202. When the processing is completed, the staff only needs to use the positioning bolts to cooperate with the positioning plates 204 provided at the ends of the first connecting plate 201 and the second connecting plate 203 to complete the assembly of the copper busbar.

[0026] By using the stamping body 100 and the connecting piece 200 in coordination, in actual use, the first connecting plate 201 and the second connecting plate 203 are inserted into the accommodating cavity 101 of the stamping body 100 through the connecting block 202, and then combined with the extrusion-type fixed connection method, compared with traditional welding and overall design, the extrusion-type fixed connection method allows a certain displacement and deformation at the connection point, which can provide a certain degree of elasticity for the entire structure. The elastic copper busbar stamping can adapt to the expansion or contraction of the material caused by temperature changes, thereby reducing the risk of structural damage caused by thermal expansion.

[0027] Second embodiment:

[0028] like Figure 1-3As shown, the first connecting plate 201 and the second connecting plate 203 are both provided with a weight-reducing cavity 400, and the weight-reducing cavity 400 connects the first connecting plate 201 and the second connecting plate 203. In actual use, by providing the weight-reducing cavity 400 on the first connecting plate 201 and the second connecting plate 203, the weight-reducing cavity 400 can reduce the overall weight of the copper busbar, reduce the consumption of copper materials, and thus reduce costs. At the same time, for power systems that require a large number of copper busbars, reducing the weight of the copper busbar can reduce the load of the entire system, simplify the installation and support structure, and at the same time, by adding the weight-reducing cavity 400 to change the copper busbar structure, the overall elasticity of the copper busbar stamping is improved.

[0029] Third embodiment:

[0030] like Figure 3 As shown, the connecting block 202 is engaged with the accommodating cavity 101 provided on the stamping part body 100, and is fixedly connected to the stamping part body 100 by being squeezed through the pressing cavities 102 provided on the accommodating cavities 101 at both ends. In actual use, the connecting blocks 202 provided at the ends of the first connecting plate 201 and the second connecting plate 203 are aligned to the accommodating cavity 101 provided on the stamping part body 100, and then the connecting blocks 202 at both ends are inserted, and finally, they are pressed together by the pressing device of the prior art, and the pressing cavity 102 is pressed tightly against the connecting blocks 202 at both ends, so that the first connecting plate 201 and the second connecting plate 203 are fixedly connected to the stamping part body 100.

[0031] By inserting and extruding the connecting block 202 into the accommodating cavity 101 provided in the stamping body 100, the assembly process of the copper busbar and the connecting block 202 can be simplified, because the connecting block 202 only needs to be embedded in the accommodating cavity 101 and fixed by extrusion, and no additional welding or complex fasteners are required. At the same time, through extrusion fixation, the contact area between the connecting block 202 and the stamping body 100 is increased, thereby providing a more uniform and stable pressure distribution, and enhancing the reliability and conductivity of the connection.

[0032] Fourth embodiment:

[0033] like Figure 2 As shown, a coating film 500 is disposed on the periphery of the first connecting plate 201 and the second connecting plate 203 , and the coating film 500 wraps the first connecting plate 201 and the second connecting plate 203 . In actual use, the coating film 500 is wrapped on the first connecting plate 201 and the second connecting plate 203 .

[0034] Through the provided coating film 500, the coating film 500 can increase the hardness of the copper busbar surface, reduce the wear caused by mechanical friction or scratching, and maintain the stability of the connection. At the same time, the coating film 500 can effectively isolate the air and the contact between the first connecting plate 201 and the second connecting plate 203, prevent copper oxidation, and ensure good electrical connection performance.

[0035] Fifth embodiment:

[0036] like Figure 1 , Figure 4 As shown, a gripping piece 300 is also sleeved on the stamping body 100, and the cavity provided by the gripping piece 300 wraps the insulating sleeve 103 therein, and the two are tightly against each other. The gripping piece 300 includes a first clamping plate 301 and a second clamping plate 303. An insert block 302 is provided at the end of the first clamping plate 301, and the insert block 302 is adapted to fit with the positioning slot 304 provided by the second clamping plate 303. In actual use, when the insulating sleeve 103 is sleeved on the middle end of the stamping body 100, the first clamping plate 301 is then clamped on one end side of the stamping body 100, and then the second clamping plate 303 is matched, and the first clamping plate 301 and the second clamping plate 303 are clamped through the insert block 302 provided on the first clamping plate 301 and the positioning slot 304 provided on the second clamping plate 303. After the two are clamped, the cavity wraps the insulating sleeve 103.

[0037] The close fit between the insulating sleeve 103 and the cavities provided in the first clamping plate 301 and the second clamping plate 303 can provide additional support for the copper busbar and enhance its structural stability.

[0038] Working principle: The staff inserts the connecting block 202 provided at the end of the first connecting plate 201 into the accommodating cavity 101 provided on the stamping body 100. Similarly, the staff inserts the connecting block 202 provided at the end of the second connecting plate 203 into the accommodating cavity 101, and then sets the insulating sleeve 103 on the middle end of the stamping body 100, and then uses the extrusion molding device, which is the existing pressing technology, to extrude the pressing cavity 102 provided at both ends of the stamping body 100, so that the pressing cavity 102 moves downward until the pressing cavity 102 is tightly connected and fixed with the connecting block 202. When the processing is completed, the staff only needs to use the positioning bolts to cooperate with the positioning plates 204 provided at the ends of the first connecting plate 201 and the second connecting plate 203 to complete the assembly of the copper busbar.

[0039] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
