Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to fig. 3, it is a schematic structural diagram of a composite busbar provided by the present invention. The composite busbar comprises at least one busbar 10. In this embodiment, the composite busbar has three busbars 10. Each busbar 10 has substantially the same structure, differing only in shape to facilitate this. It is contemplated that the composite busbar may include other functional structures, such as studs disposed on the busbar 10, terminals disposed on the studs, etc., which are well known to those skilled in the art and will not be described in detail herein.
The busbar 10 includes a body 11, at least one terminal 12 disposed on the body 11, and an insulating layer 13 disposed on the body 11 and the terminal 12. It is contemplated that the body 11 and the terminal 12 are made of conductive material, typically copper, brass, etc. The body 11 may be a straight flat plate, and the width and length of the body 11 may be according to the actual requirement, such as the magnitude of the connected voltage. The terminals 12 have at least one, and typically two, one being a positive terminal and the other being a negative terminal. Of course, three or four can be provided according to actual needs. The body 11 and the terminal 12 are integrally formed, and may be manufactured through a stamping process and a bending process. The terminal 12 includes a creepage part 121 connected to the body 12, a connection part 122 connected to the creepage part 121, and a mounting hole 123 provided on the connection part. Since the terminal 12 needs to be connected to the positive and negative electrodes, in order to prevent the generation of the creepage phenomenon, the wiring portion 122 is usually located at a certain distance from the body 11, i.e., the creepage portion 121. The extending direction of the creepage part 121 may be perpendicular to the extending direction of the wiring part 122, but the bending mode may be various, such as arc bending or right angle bending. In this embodiment, the bending manner is an arc-shaped bending manner, and therefore, the creepage part 121 includes a connecting part 124 connected with the body 11, and a bending part 125 connected between the connecting part 124 and the wiring part 122.
The insulating layer 13 is coated on the body 11 and the terminal 12 and is integrally formed. The insulating layer 13 is made of an insulating resin, specifically, a resin that can be melted between 160 degrees and 200 degrees. In this embodiment, the insulating resin is an epoxy resin. The method for coating the body 11 and the terminal 12 with the insulating resin comprises the steps of firstly heating the body 11 and the terminal 12 to 160-200 ℃, and then putting the heated body 11 and the terminal 12 into the powder of the insulating resin forming the insulating layer, wherein the insulating resin is adhered to the body 11 and the terminal 12 at the temperature of 160-200 ℃. When the body 11 and the terminal 12 are taken out of the insulating resin, the insulating resin attached to the body 11 and the terminal 12 is melted due to the high temperature of the busbar, and the melted insulating resin is self-leveled under the action of gravity to form a plane and forms a smooth plane under the action of surface tension. It is of course conceivable that for some locations where it is not necessary to cover the insulating layer 12, gummed paper should be first applied to avoid adhesion of molten insulating resin, thereby forming the insulating layer 13 where insulation is required for the body 11 and the terminals 12. Further, as for the terminal 12, the creepage part 121 is provided with the insulating layer 13 thereon. In order to make an electrical connection, one of two surfaces of the wire connecting portion 122, which intersect with the axial direction of the mounting hole 123, is exposed out of the insulating layer 13. It is conceivable that the portion of the surface exposed outside the insulating layer 13 needs to be pasted with a sticker when adhering the insulating resin. In the present embodiment, the creepage part 121 includes a connecting part 124, and a bending part 125. The bent portion 125 is arc-shaped, and the insulating layer 13 is also disposed on the bent portion 125. When the creepage part 121 and the wiring part 122 are directly bent, that is, the bent part is right-angled, and at this time, the edge of the insulating layer 13 is flush with the intersection line of the creepage part 121 and the wiring terminal 122.
Compared with the prior art, the utility model provides an insulating layer 13 on female 10 of arranging of each in compound female row is integrated into one piece, has consequently reduced a lot of processes, like the PET membrane hot pressing process of the both sides face among the prior art, the alignment process of PET membrane, encapsulating process etc to can reduce and reduce manufacturing cost. Meanwhile, in manufacturing the insulating layer 13, the body 11 and the terminal 12 are heated to between 160 degrees and 200 degrees, and then the heated body 11 and the terminal 12 are put into the powder of the insulating resin forming the insulating layer, which adheres to the body 11 and the terminal 12. When the body 11 and the terminals 12 are removed from the insulating resin, the insulating resin adhered to the body 11 and the terminals 12 is melted due to the high temperature of the body 11 and the terminals 12, and the melted insulating resin is self-leveled by gravity while forming a smooth plane by the surface tension, thereby forming the insulating layer where the body 11 and the terminals 12 need to be insulated.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
