Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to terminals provided for electrical connections in unit parts that are often incorporated into various electronic devices such as small power supply devices. be.

[Conventional technology]

Conventionally, small power equipment, etc. are often equipped with a flat terminal a specified in JIS C 2809, commonly known as a Faston terminal, as shown in Fig. 4, or a pin terminal b, as shown in Fig. 5. For example, if the manufacturer of the power supply device thinks that it cannot be installed on the printed circuit board based on the capacitance, physical dimensions, shape, etc. of the device, it may be necessary to install a flat terminal on the printed circuit board. Pin terminals were provided for items that could be incorporated into the system.

[Problem that the invention attempts to solve]

However, this does not pose a problem for products that are large or small enough for everyone, including the user, to make the above judgment, but for products with shapes in between, some users may If a manufacturer wants to incorporate it into a printed board, but other users do not want it to be incorporated into one of the terminals, the market will be narrowed, and manufacturers will be forced to limit the market for products that are the same but have different terminals. However, in recent years, advances in technology have led to the miniaturization of equipment, such as complicating production and sales management.
As the number of items included in this range has increased,
This trend is becoming more and more noticeable.

[Means for solving problems]

As a specific means to solve the above-mentioned problems, the present invention provides a protrusion in the center of the head of the flat terminal to form a pin terminal part, so that only the pin terminal part protrudes from the case mounting surface. By providing a composite terminal characterized in that the mounting surface of the flat terminal is formed into a recessed part, the terminal can be used either on a printed circuit board or not. This solves the above problems.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in the drawings.

The symbol 1 in FIG. 1 is a flat terminal according to the present invention, and a pin terminal part 3, which is a protrusion, is provided at the center of the upper end of a faston part 2, which has the same shape as the faston terminal described in the conventional example. be. The width of the pin terminal portion 3 is preferably comparable to the lead wire portion of other commonly used electronic components, and the height thereof is greater than that of a commonly used printed circuit board. This is preferable.

FIG. 2 shows an embodiment in which the flat terminal 1 formed in the shape described above is assembled into a unit part 4 which is, for example, a power supply device. The flat terminal 1 is assembled by forming a recess 5 having a sufficient width for attaching and detaching the flat terminal 1 and having the same depth as the faston part 2 having the same shape as the faston terminal of the flat terminal 1. There is.

[Effect]

With the configuration described above, when the unit component 4 is not incorporated into the printed circuit board, electrical connection can be made by inserting the female terminal of the Faston terminal into the flat terminal, and the unit component 4 can be incorporated into the printed circuit board. In this case, as shown in FIG. 3, a hole 7 of an appropriate diameter is passed through the printed circuit board 6 to be mounted, and the pin terminal portion 3 of the flat terminal 1 is inserted into the hole 7 and soldered. It is possible to make a physical connection.

[Effect of idea]

As explained above, by forming a flat terminal with a faston part and a pin terminal part having the same shape as the faston terminal, and by assembling it into the recess of the unit component so that only the pin terminal part protrudes from the case mounting surface. Since the same unit parts are compatible whether or not they are incorporated into a printed circuit board, it is an excellent solution because both the manufacturer and the user can avoid complicated arrangements and other management issues. It is effective.
