Description

Technical Field

[0001] The utility model belongs to the technical field of automobile battery clamps, in particular to an automobile battery clamp blank coated with a copper strip. Background Art

[0002] The car battery clamp is mainly made of metal materials, and has the characteristics of good electrical conductivity, corrosion resistance, and wear resistance. In the maintenance and repair of car batteries, the battery clamp is one of the indispensable tools, which is used to connect the positive and negative poles of the battery to transmit and measure the current. The car battery clamp includes a clamp body and a wire fixedly arranged in the clamp body. The end of the wire is provided with a copper sleeve body, and the sleeve body is located on the clamping surface of the clamp. The sleeve body is provided with a tooth shape formed by pressing, so as to ensure the stability during clamping.

[0003] The existing sleeve generally uses copper tubes directly. The specific steps are: select a copper tube of suitable diameter and cut it into sections, then put the cut copper tube on the outside of the copper wire of the wire to form a blank. The blank will be pressed and tightly connected with the copper wire of the wire in the subsequent processing process to form a tooth shape.

[0004] During the production process, due to the different square numbers of different wires, the required copper tube diameters are also different. In order to ensure stable production, the factory needs to prepare a large number of copper tubes of different sizes. However, storing a large number of copper tubes of different specifications will not only affect the circulation of funds, but the multiple codes of the copper tubes will also increase the difficulty of inventory records. At the same time, the copper tube cannot be completely fitted with the copper wire of the wire in the blank state. Therefore, during the blank transmission process, the copper tube and the copper wire are easily misaligned, affecting the quality of the finished product. The outer contours of the copper sleeve and the outer contours of the wire are both cylindrical, which is not easy to position and is easy to roll during stamping, affecting production quality. Utility Model Content

[0005] In view of this, the utility model provides a car battery clamp blank coated with copper strip to solve the above problems.

[0006] A blank for an automobile battery clamp coated with a copper strip comprises an electric wire and a copper sleeve formed by surrounding the copper strip and wrapped around one end of the electric wire and having a seam. The electric wire comprises an electric wire body and a plurality of copper wires hinged in the electric wire body. The copper wires are hinged to each other to form a cylindrical copper core. The copper core extends from one end of the electric wire body to form a mounting portion, the copper strip is sleeved on the mounting portion, and the outer contour of the copper sleeve is rectangular. The inner wall of the copper sleeve abuts against the copper core.

[0007] Furthermore, the copper strip has a thickness of 0.25 mm to 0.5 mm.

[0008] Furthermore, the length of the mounting portion is not less than the width of the copper strip of the copper sleeve.

[0009] Furthermore, the cross section of the copper sleeve is square.

[0010] Furthermore, the copper sleeve is a single-layer structure, and the two ends of the copper belt are spaced apart to form a seam.

[0011] Furthermore, the seam is located in the middle of the side surface of the copper sleeve.

[0012] Furthermore, the end of the copper sleeve is flush with the end of the copper core.

[0013] Compared with the prior art, the automobile battery clamp blank covered with copper tape provided by the utility model can adapt to wires of different diameters by winding the copper tape at the end of the wire, avoiding the increase of material coding of the copper sleeve due to different sizes of the wires, and the copper tape fits the copper core of the wire more closely, which can reduce the voltage to the maximum extent, thereby reducing the number of squares of wires and achieving the effect of cost reduction.

[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] like Figures 1 to 4As shown, it is a schematic diagram of the structure of the copper-strip-coated automobile battery clamp blank provided by the utility model. The copper-strip-coated automobile battery clamp blank includes a wire 10 and a copper strip 20 coated on one end of the wire 10. The copper-strip-coated automobile battery clamp blank also includes some other functional modules, such as an insulating layer coated on the outside of the wire, a wiring part arranged on the other end of the wire, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0020] The electric wire 10 includes an electric wire body 11 and a plurality of copper wires 12 arranged in the electric wire body 11 and intertwined with each other. The copper wires 12 are hinged with each other to form a cylindrical copper core 13. The copper wires 12 extend from one end of the electric wire body 11 to form a mounting portion 14. The copper wires 12 located at the mounting portion 13 are exposed on the outside and the ends are flush.

[0021] The copper strip 20 is wrapped around the outside of the mounting portion 14 of the electric wire 10, thereby forming a C-shaped copper sleeve 21. The outer contour of the copper sleeve 21 is rectangular, so that the position of the copper sleeve 21 is stable on the processing station during the processing, which is convenient for processing. The copper sleeve 21 is a single-layer structure, and the two ends of the copper strip 20 are spaced to form a seam 22, thereby reserving a certain space for the deformation and extension of the copper strip 20 after subsequent processing. The seam 22 is located on the side of the copper sleeve 21 and in the middle of the side of the copper sleeve 21. In this embodiment, the cross-section of the copper sleeve 21 is square, so that the inner wall of the copper sleeve 21 can abut against the copper core 13.

[0022] The length of the mounting portion 14 is not less than the width of the copper belt 20 , thereby ensuring that the copper belt 20 can be completely covered outside the mounting portion 14 .

[0023] The copper strip 20 is made of red copper or brass. Brass is relatively cheap and easy to process, and has good electrical and thermal conductivity. Red copper has beautiful color, good corrosion resistance and wear resistance, and excellent mechanical properties.

[0024] The thickness of the copper strip 20 is 0.25 mm-0.5 mm, which can reserve a certain margin for the deformation of the copper strip 20 in subsequent processing.

[0025] The copper strip 20 is subjected to surface pickling or silver-plating, gold-plating, tin-plating or nickel-plating treatment. Pickling can remove the oxide layer on the metal surface, improve the surface quality of the metal, and make it smoother and denser. Silver-plating, gold-plating, tin-plating or nickel-plating can enhance the corrosion resistance of the metal, and also improve the electrical conductivity and thermal conductivity of the metal. These treatments can only prevent the formation of an oxide layer on the surface of the copper strip 20, thereby ensuring that the copper strip 20 is in close contact with the iron core.

[0026] The end of the copper sleeve 21 is flush with the copper core 13 to ensure that the copper core 13 does not exceed the end of the copper sleeve 21 during subsequent processing.

[0027] In subsequent processing, the blank will be stamped so that the copper strip 20 and the copper core 13 are tightly combined, and a large tooth shape is formed on the surface of the copper strip 20, such as Figure 3 At this time, a processing hole is opened on the copper belt 20, and indentations are respectively provided at both ends of the hole to enhance the bonding tightness between the copper belt 20 and the copper core 13.

[0028] Compared with the prior art, the copper-tape-wrapped automobile battery clamp blank provided by the utility model can adapt to wires 10 of different diameters by winding a copper tape 20 at the end of the wire 10, thereby avoiding the need to increase the material coding of the copper sleeve due to the different sizes of the wire 10, and the copper tape 20 fits the copper core of the wire 10 more closely, which can reduce the voltage to the maximum extent, thereby reducing the number of squares of wires and achieving the effect of cost reduction. The copper tape 20 is surrounded to form a copper sleeve 21 with a rectangular outer contour, so that the copper sleeve 21 can be stably positioned on the processing station during processing, which is convenient for processing.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
