In FIG. 5, (5) is a board for connection or mounting, on which a plurality of module power supplies (1) are mounted and connecting pins (3) are connected. (7) is a heat sink, and the module power supply (
It is attached to the heat sink (4) of 1).

In FIG. 6, a plurality of module power supplies (1) are connected by connecting wires (8).

In the above configuration, when purchasing a power supply device or increasing the capacity by connecting multiple module power supplies (1) shown in Figure 4 to each other, soldering connection pins (3
) must be connected to each other, for this the fifth
As shown in the figure, the module power supply (1) is mounted on the board (5) for mounting connection, and the pattern of the board (5) is passed through.
It is necessary to connect the module cables g(1) by connecting them to each other or by soldering the connecting wires (8) shown in Figure 6 to the soldering connection pins (3). be.

[Problem to be solved by the invention]

Conventional module power supplies are configured as described above, so when connecting between module power supplies, it is necessary to connect connection pins for soldering.
Connections must be made by soldering the electric wires, which poses problems such as not being easy to connect and causing connection errors.

In addition, since the module power supply (1) is molded in the molded part (2), if a fuse to protect against overcurrent or a temperature fuse to protect against overheating is enclosed, it cannot be replaced, so it is virtually impossible to install fuses. there were.

This invention was made to solve the above-mentioned problems, and provides a module power supply that allows easy interconnection between module power supplies and can protect against overcurrent or overheating. The purpose is to

[Means to solve the problem]

The present invention is the following module power supply.

(1) In a power supply module unit in which the circuit part is encapsulated in a molding material, an input/output terminal part provided on the module power supply, an external connector that connects the input/output terminal parts of multiple module power supplies, and Modular power supply with installed fuse.

(2) The module power supply according to (1) above, wherein the fuse is a temperature fuse.

[For production]

In the module power supply according to the present invention, a plurality of module power supplies can be easily connected by connecting external connectors for interconnection to input/output terminal portions of adjacent module power supplies. A fuse or temperature fuse attached to the external connector can also protect the module power supply from overcurrent or overheating.

As described above, the module power supplies according to the present invention can be easily connected to each other by external connectors having an overcurrent protection function, and can constitute a safe power supply device.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a perspective view of an external connector, and FIG. 3 is an exploded perspective view showing a connected state. The same reference numerals indicate the same or equivalent parts.

(11) is a female input/output terminal provided at both ends of the module power supply (1), and (12) is a male for connecting the input/output terminal (11) of the adjacent module power supply 11iX (1). type external connector, (13) is the external connector (1
(2) is the connection pin protruding from both sides, (14) is the fuse sealed inside the external connector (12), (1)
5) is a collar for fixing the external connector (12).

In the module power supply configured as described above, when connecting multiple module power supplies (1) to each other to configure a power supply or increase capacity, the external connector (
12) is inserted into the input/output terminal portion (11) of the module power supply (1) and fitted to connect electrically and mechanically. Here, the external connector (12) is a connection pin (13) and a fuse (14) encapsulated in a molded material such as resin, and is not only electrically connected but also connects the heat sink (4) and the fuse (14). 15) Because it is sandwiched between

protect.

In the above embodiment, a fuse that melts due to overcurrent is used as the fuse (item 4), but if a temperature fuse is used, the module power supply (1) can be protected from overheating.

Further, in the above embodiment, only a two-pole external connector (12) is shown, but a plurality of more than two poles may be provided. Furthermore, the shapes of the connecting pins (13) on both sides may be mutually changed to give directionality to the external connector (12).

Further, by providing a recess or a protrusion on the external connector (12), attachment/detachment and handling can be facilitated.

〔Effect of the invention〕

As described above, according to the present invention, the soldering connection pins have been changed to input/output terminals and external connectors, so when connecting multiple module power supplies to each other, it can be easily connected, and the board This eliminates the need for soldered connection parts such as cables and wires, which eliminates connection errors and improves reliability. In addition, the external connector also functions as a fuse or temperature fuse, making it easy to protect the module power supply from overcurrent or overheating, and the fuse can be replaced simply by replacing the external connector.
