Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a busbar structure for continuously connecting wiring terminals in electronic equipment.

<Prior Art and Problems> As a conventional bus bar structure, there is one shown in FIG. 1, for example. In the figure, 1 is a plurality of wiring terminals arranged in parallel in an electronic device, 3 is a terminal support, and 2 is a bus bar. This bus bar 2
are arranged so as to contact the shaft portions of the parallel terminals 1 formed of strip-shaped sheet metal, and the shaft portions of the terminals 1 and the contact portions of the bus bar 2 are connected via the soldering portions 9,
This bus bar 2 connects the terminals 1 continuously.

However, in the case of the conventional busbar structure,
When the length of the wiring terminal 1 is generally about 10 to 20 mm and a bus bar with a large current capacity is required,
Although it is possible to increase the width or thickness of the bus bar 2 made of a strip-shaped sheet metal, increasing the thickness often causes soldering defects, which is not preferable. In addition, increasing the width of the bus bar 2 does not cause any significant problems during assembly work, but if the width exceeds the terminal length, it may become difficult to wire the terminal 1 to which the bus bar 2 is attached. There was a problem.

<Objective of the invention> An object of the invention is to provide a busbar structure that eliminates the drawbacks of the conventional busbar structure and that can gradually obtain an appropriate current capacity with standardized busbar sizes.

<Configuration of the invention> The busbar structure according to the invention has a busbar structure that continuously connects a plurality of wiring terminals arranged in parallel in an electronic device, and has a plurality of small through holes that engage with the terminals. Busbars made of band-shaped sheet metal provided with a cylindrical body are alternately engaged with the terminals with small cylindrical bodies made of heat-resistant and poor heat conductive material having an inner diameter that engages with the terminals, and the small through holes of the busbars and the engagement portions of the terminals are stacked. The above-mentioned conventional problems are solved by making the connection fixed.

<Example> Hereinafter, an example of the present invention will be described based on FIG. 2. In addition, in the following, parts common to the conventional one are given the same reference numerals, and redundant explanations will be omitted. 4 in the diagram
is a bus bar made of a band-shaped sheet metal, and this bus bar 4 is provided with a plurality of small through holes 6 that engage with the terminals 1 arranged in parallel. 4 is adapted to be attached to terminal 1. Reference numeral 5 denotes a small cylindrical body made of a heat conductor with poor heat resistance, which has an inner diameter that engages with the terminal 1, and is attached to the terminal 1 so as to be stacked alternately with the bus bar 4. The installation procedure is as follows: First, the small cylindrical body 5 is engaged with an appropriate location of the terminal 1 to which the bus bar is to be attached, and the bus bar 4 is then engaged with the terminal from above, and the small cylindrical body 5 and the bus bar 4 are stacked one after another. The small through hole 6 of No. 4 and the engaging portion of the terminal 1 are connected by a soldering portion 7 formed by dipping with solder. In this case, if a large current capacity is required, the required current capacity can be easily obtained by stacking the bus bars 4 according to the current capacity. Further, when attaching the bus bar 4, wiring using the cable 8 can be performed in a portion where the small cylindrical body 5 is not mounted.

<Effects of the invention> As explained above, since the busbar structure of the present invention is configured as described above, it is possible to obtain an arbitrary current capacity in stages by laminating the small cylindrical body and the busbar. By mounting the small cylindrical body, it is possible to prevent the terminal support from being damaged by heat during soldering, and furthermore, cables can be routed in areas where the small cylindrical body is not mounted, providing greater freedom in design. It also has the effect of being high.
