AI Technical Summary
[0003]现有的加热片随着技术的进步,具有多种不同类型基材制作形成的加热片,不单单仅有云母板制作的一种加热片,而众多加热片的板体与接线都是分段设置,即在使用时,先安装加热片在通过人工手动接线,此种方式在对加热片使用时显得较为繁琐,增加了安装步骤和工序,并不利于安装操作,同时加热片内部为除去刻蚀的加热电路外,其余部分为实心板体,在加热片受到弯折或压迫时,实心板受压应力无处释放,轻则导致板体形变翘起,重则出现板体断裂损坏的情况,也不利于加热片的使用安全
[0012]本实用新型通过加热片主体、加热电路、空腔、通槽和接线的设置,接线与加热电路焊接后,形成一体化得到加热片主体,在使用时就无需安装焊接额外的线束,使整个加热片主体使用更加方便快捷,而空腔和通槽都为加热片主体预留了空间,加热片主体在整体受压或弯折时,都有足够的空间将压迫折弯产生的应力进行释放,也能够防止加热片主体整体在加工生产时,压迫产生的应力无法释放,出现边缘翘起的情况,从而提升了加热片主体的加工生产质量。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating element technology, specifically to an integrated heating element for wire harnesses. Background Technology
[0002] A heating element, also known as a heat exchanger, is a sheet-shaped electric heating element that generates heat. Utilizing the excellent insulation and high-temperature resistance of mica sheets, heating elements use mica sheets as a framework and insulation layer, supplemented by galvanized or stainless steel plates for support and protection. They can be made into various sheet shapes, such as plates, sheets, cylinders, cones, tubes, and circles.
[0003] With technological advancements, existing heating elements are now made from various types of substrates, not just mica sheets. Many heating elements have segmented boards and wiring, requiring manual wiring after installation. This method is cumbersome, increasing installation steps and procedures, and is not conducive to operation. Furthermore, apart from the etched heating circuitry, the interior of the heating element is a solid board. When the heating element is bent or compressed, the stress on the solid board has nowhere to dissipate, leading to deformation and warping, or even breakage and damage, which also compromises the safety of the heating element.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings and proposed an integrated heating element for wire harnesses. Utility Model Content
[0005] The purpose of this invention is to provide an integrated heating element for wire harnesses to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated heating element for a wire harness, comprising a heating element body, a heating circuit being provided on the inner wall of the heating element body, a cavity being formed in the inner wall of the heating element body at the gap of the heating circuit, a through groove being formed in the middle of the front side of the surface of the heating element body, and wiring wires being connected through the left and right sides of the front end of the heating element body, the wiring wires being connected to the heating circuit, and the surface of the connection part between the wiring wires and the heating circuit being provided with electroplated silver paste.
[0007] Preferably, the heating element body is made of polyimide, and the heating circuit is etched and configured as an "S" shaped circuit.
[0008] Preferably, the cavity does not penetrate the heating element body, and the spacing between the through slots is set to be between 0.5mm and 0.8mm.
[0009] Preferably, the wiring is a tin-plated copper core wire, and the wiring is welded and fixed to the heating circuit.
[0010] Preferably, the electroplated silver paste covers the connection between the wiring and the heating circuit, sealing and filling the gaps at the entire connection.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention integrates a heating element body, a heating circuit, a cavity, a through slot, and wiring. The wiring is welded to the heating circuit to form a single integrated heating element body. This eliminates the need for additional wiring harnesses during use, making the entire heating element body more convenient and efficient to use. The cavity and through slot provide ample space for the heating element body, allowing for stress release when it is subjected to pressure or bending. This also prevents stress buildup during manufacturing, which could lead to edge warping, thus improving the overall quality of the heating element body. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the overall three-dimensional structure of the present invention;
[0014] Figure 2 This is a cross-sectional view of the main body of the heating element of this utility model.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-2 As shown, an integrated heating element for a wire harness includes a heating element body 1. A heating circuit 2 is provided on the inner wall of the heating element body 1. A cavity 3 is opened on the inner wall of the heating element body 1 at the gap of the heating circuit 2. A through groove 4 is opened in the middle of the front side of the surface of the heating element body 1. Wiring wires 5 are connected through the left and right sides of the front end of the heating element body 1. The wiring wires 5 are connected to the heating circuit 2, and the surface of the connection part between the wiring wires 5 and the heating circuit 2 is provided with electroplated silver paste 6.
[0018] By adopting the above technical solution, both the cavity 3 and the through groove 4 reserve space for the heating element body 1. When the heating element body 1 is subjected to pressure or bending, there is enough space to release the stress generated by the pressure and bending. It can also prevent the stress generated by the pressure from not being released during the processing and production of the heating element body 1, resulting in the edge warping.
[0019] Furthermore, the heating element body 1 is made of polyimide, and the heating circuit 2 is etched and configured as an "S" shaped circuit.
[0020] By adopting the above technical solution, the heating element body 1 made of polyimide has high-performance insulation effect and excellent high temperature resistance, chemical corrosion resistance and electrical insulation properties, thus making the heating element body 1 have a longer service life.
[0021] The “S”-shaped heating circuit 2 can fully cover the entire heating element body 1, making the heating element body 1 heat up more evenly.
[0022] Furthermore, the cavity 3 does not penetrate the heating element body 1, and the spacing between the through slots 4 is set between 0.5mm and 0.8mm.
[0023] By adopting the above technical solution, the cavity 3 does not penetrate the heating element body 1, making the appearance of the heating element body 1 more neat.
[0024] Furthermore, wiring 5 is a tin-plated copper core wire, and wiring 5 is welded and fixed to heating circuit 2;
[0025] The electroplated silver paste 6 is applied to the connection between the wiring 5 and the heating circuit 2, sealing the gap at the entire connection.
[0026] By adopting the above technical solution, after the wiring 5 is welded to the heating circuit 2, an integrated heating element body 1 is formed, so there is no need to install or weld additional wiring harnesses during use.
[0027] The electroplated silver paste 6 covers the joint seams, making the connection points neater and the connection more stable.
[0028] Working principle: When using this integrated heating element, firstly, the wiring 5 is soldered to the heating circuit 2 to form an integrated heating element body 1. This eliminates the need for additional wiring harnesses during use, making the entire heating element body 1 more convenient and efficient to use. During operation, the heating circuit 2 is powered by the wiring 5, which heats the entire heating element body 1. Both the cavity 3 and the through slot 4 provide space for the heating element body 1, ensuring sufficient space to release stress generated by pressure or bending. This design is also effective in the production of the heating element body 1, preventing stress buildup during processing and causing edge warping. This is the working principle of the integrated heating element.
