Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a high-current plug spring and a spring sheet processing method thereof. Background Art

[0002] High current spring is an electrical connection element used for high current transmission.

[0003] In the related art, a high current plug spring includes a copper bar, and two opposite ends of the copper bar are provided with spring plates. The spring plates are elastic and gradually approach the direction away from the copper bar.

[0004] When the existing conductive connector is electrically connected to the plug spring, the conductive connector is inserted between the two springs to deform the two springs. At the same time, the two springs apply a clamping force to the conductive connector to prevent the plug spring from being easily separated from the conductive connector. The plug spring is used in a high current environment for a long time, so that the spring is in a high temperature state for a long time, the elasticity of the spring decreases, and the clamping force on the conductive connector is reduced, resulting in a power outage between the conductive connector and the spring, so it needs to be improved. Summary of the invention

[0005] In order to improve the connection stability between the plug spring and the conductive plug connector, the present application provides a high-current plug spring and a method for processing the spring leaf thereof.

[0006] The present application provides a high current plug spring and a reed processing method thereof, which adopts the following technical solution:

[0007] A high current plug spring, comprising a copper bar, spring sheets arranged on both sides of the copper bar, and a spring sheet located on the side of the spring sheet facing away from the copper bar, wherein the spring sheet comprises a first connecting plate and a contact sheet for connecting to the copper bar, and the contact sheet is cut by wire cutting to form a plurality of spring claws with a spacing of 0.1 mm to 0.6 mm;

[0008] The contact piece includes an outward expansion section extending outward from the connection with the first connecting plate and tilted in the direction away from the other spring piece, a spring arm section extending from the outward expansion section away from the first connecting plate and close to the other spring piece, an arc section protruding in the direction of the other spring piece from the spring arm section away from the outward expansion section, and a guide section tilted from the arc section away from the spring arm section and away from the other spring piece;

[0009] The spring sheets each include a second connecting plate that cooperates with the riveted portion, an extension section extending from the second connecting plate in a direction away from the riveted portion and in a direction away from another spring sheet, and a plurality of spring claws connected to the extension section and extending in a direction away from the second connecting plate, wherein the spring claws abut against the spring claws and apply a force to the spring claws.

[0010] By adopting the above technical solution, the spring claws are cut by wire cutting so that the spacing between adjacent spring claws is only 0.1mm-0.6mm, which greatly increases the arrangement density of the spring claws. More spring claws can be set under the same size to increase the conductive path. The spring claws can also carry a larger current. More spring claws increase the heat dissipation area and improve the heat dissipation performance of the spring. Other conductive connectors are guided to the position between the two springs through the guide section, and the spring arm section and the arc section enable the deformed spring to better provide a reset force to clamp the conductive connector. An elastic claw is set to apply a force to the spring claw, thereby increasing the force of the spring claw on the conductive connector, so that the spring claw is more stably electrically connected to the conductive connector.

[0011] Optionally, the spring claw includes an elastic arm section extending from the extension section in a direction away from the second connecting plate, and a force-applying section formed from the elastic arm section in a direction away from the extension section and protruding in the direction of another elastic sheet. The number of spring claws is half the number of spring claws, and the force-applying section of each spring claw abuts against two spring claws.

[0012] By adopting the above technical solution, each spring claw is set to apply a force to the abutment of two spring claws, so that only a small number of spring claws are needed to meet the requirements, and there is no need to process narrow and thin spring claws, thereby reducing the processing accuracy and difficulty.

[0014] By adopting the above technical scheme, when the copper busbar, the spring sheet and the spring sheet are riveted, the spring sheet and the spring sheet are first placed on the copper busbar, and then the operating shaft is rotated to make the operating shaft abut against the spring sheet, and the spring sheet is driven to deform, so that the first connecting plate fits with the second connecting plate, and the first through hole, the second through hole and the riveting hole are aligned, so that it is convenient for the staff to pass the rivet through the copper busbar, the spring sheet and the spring sheet to connect the three; when the force of the spring sheet on the spring sheet is weakened, the operating shaft is driven to rotate to move the operating shaft toward the riveting part, so that the spring sheet is deformed, and the force of the spring sheet on the spring sheet is increased. When the conductive plug-in component is inserted between the two spring sheets, the clamping force of the spring sheet on the conductive plug-in component is increased, so that the conductive plug-in component is not easily separated from the plug spring.

[0015] Optionally, a mounting groove is provided on the riveted portion, a rotating shaft is rotatably connected in the mounting groove, the operating rod is sleeved outside the rotating shaft, and a limiting component for limiting the rotation of the operating rod is provided on the operating rod.

[0018] By adopting the above technical solution, when the limiting block is in contact with the end surface of the riveted portion facing the spring sheet, the operating rod is not easy to rotate because the limiting block is limited by the riveted portion.

[0019] Optionally, when the operating rod is in use, an operating hole is provided on the end face of the operating rod facing the spring sheet, the operating block is inserted into the operating hole, a clamping block is provided on the end face of the operating rod facing the rotating shaft, the clamping block is located on the side of the operating rod away from the operating shaft, and a clamping groove for inserting the clamping block is provided on the end face of the riveted part along the length direction.

The number of the elastic claws (33) is half the number of the spring claws, and the force-applying section (332) of each elastic claw (33) abuts against two spring claws.

3. A high current plug spring according to claim 1, characterized in that: A hook portion (322) is provided on the end surface of the extension section (32) facing the outward expansion section (221); an insertion hole (2211) is provided on the outward expansion section (221) for the hook portion (322) to pass through; the hook portion (322) can be hooked and matched with the outward expansion section (221); when the hook portion (322) is hooked and matched with the outward expansion section (221), the extension section (32) is in a deformed state, the spring claw (33) abuts against the spring claw and applies a force to the spring claw, and the first connecting plate (21) and the second connecting plate (31) are in contact with each other.

4. A high current plug spring according to claim 1, characterized in that: The end surface of the first connecting plate (21) facing the mounting portion (12) is provided with a connecting portion (4), the end surface of the connecting portion (4) away from the first connecting plate (21) is connected to the second connecting plate (31), and the elastic sheet (3), the spring sheet (2) and the connecting portion (4) are integrally formed.
