DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Example 1

[0027] Reference Figure 1 to Figure 4 The present embodiment provides a high-power power distribution unit, including a shell 100, in which a plurality of output modules 101 are arranged along the length direction, and the output modules 101 are provided with copper pins 102, and each copper pin 102 is welded and connected through a copper conductive strip 103.

[0028] At present, the main conductor of the high-power power distribution unit is brass, and the conductive pin of the output module is copper, which leads to excessive temperature rise of the power distribution unit, low conductivity efficiency and low energy utilization. Due to the limitations of spot welding, two conductors of the same copper material cannot be welded together, so only the main conductor of brass and the conductor of the output module of copper can be welded firmly and the current can be normal. Changing it to the copper conductive strip 103 and the copper pin 102 of the present application can improve the conductivity efficiency, but flux is needed to weld them together. However, the non-solid flux currently used is easy to pollute the environment and takes a lot of time. The present application uses a non-chip copper-based solder strip 108 for welding, which is convenient to operate and saves time.

[0029] Specifically, the composition of the copper-based solder strip 108 may be: 5-7% nickel, 8-10% tin, 5-7% phosphorus, and the remaining component is copper.

[0030] Hanging ears 104 are provided on both sides of the housing 100 for mounting and fixing the entire power distribution unit.

[0031] A junction box 105 is disposed in the housing 100 . The junction box 105 is connected to the copper conductive bar 103 via a wire 107 . A cover groove 105 a is disposed on the junction box 105 .

[0032] The junction box 105 is used to connect the power distribution unit to the circuit.

[0033] The cover groove 105a is used to leave an opening for wiring.

[0034] A pressing plate 105b is disposed in the cover groove 105a, and a pressing groove 105c is disposed on the pressing plate 105b.

[0035] A cover plate 106 is disposed at the cover groove 105a, and a buckle plate 106a is disposed at one end of the cover plate 106, and the buckle plate 106a is embedded in the pressing groove 105c.

[0036] The buckle plate 106a is a U-shaped plate, which has elastic force and fixes the cover plate 106 through the elastic force. Furthermore, an embedding block is provided at the other end of the cover plate 106, and an embedding groove is provided at one end of the cover groove 105a. The embedding block is connected to the embedding groove to achieve fixation.

[0037] In this way, the cover 106 can be opened conveniently for wiring.

[0038] The side of the housing 100 is provided with a wiring hole.

[0039] Example 2

[0040] Reference Figures 1 to 6This embodiment also discloses a welding mechanism based on the aforementioned high-power power distribution unit to solve the problem that copper cannot be directly welded to copper, and the problem that non-solid flux in the prior art is easy to splash and pollute the environment.

[0041] Furthermore, it also includes a soldering station 200 and a welding robot arm 201 , the copper pin 102 is placed on the soldering station 200 , and a tungsten rod head 202 is provided at the end of the welding robot arm 201 .

[0042] A copper-based solder strip 108 is disposed on the copper pin 102 , and a copper conductive strip 103 is disposed on the copper-based solder strip 108 .

[0043] The copper-based solder strip 108 may contain 5-7% nickel, 8-10% tin, 5-7% phosphorus, and the remaining copper, and does not contain any toxic or harmful components, and is a new type of environmentally friendly solder.

[0044] The specific working method is electric welding, using a tungsten rod head and a non-chip medium welding method to solve the limitation that the same copper material cannot be welded. The main circuit conductor is made of copper, and the output module pins are also made of copper. The high-power power distribution unit welded by spot welding has high power utilization, low product temperature rise, and more reliable and safe quality. At the same time, the tungsten rod head does not stick during welding, and the welding is fast, reliable and stable.

[0045] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
