Description of the Related Art As an arrangement for connecting an instrument such as a temperature controller or a converter for converting the output of the temperature controller to a DIN rail, for example, those shown in FIGS. 8 and 9 are known. That is, a plurality of circuit boards 5 are supported on the terminal board 3 on which the male connector contacts 1 are protruded, and the meter connector 9 which is entirely covered with the case 7 is fitted into the male connector contacts 1 (see FIG. 1). A base 15 having terminals provided with a socket 11 having a socket 11 (not shown) and an external connection terminal 13 (not shown in FIG. 8) to which a wiring cable (not shown) to the outside is connected is fixed to a DIN rail 17, and an instrument is provided. The instrument connector 9 is fixed to the base 15 with a terminal by fitting the male connector contact 1 of 9 into the socket 11 of the base 15 with a terminal, and a hook 19 provided on the base 15 with a terminal (omitted in FIG. 9). Is secured to the instrument 9 to ensure secure fixation.

The instrument 9 is shown in a state where the case 7 is slightly pulled out of the terminal board 3 in FIG. In the base 15 with terminals, each female connector contact of the socket 11 is connected to each external connection terminal 13, while the number of connector contacts (the number of pins) in the base 15 with terminal and the instrument 9 is It is standardized in advance, such as 8-pin, 11-pin, 14-pin, and 20-pin. The base 15 with terminals having a larger number of connector contacts naturally has a larger shape.

１５のコネクタ接触子のピン数に応じて搭載機能数が限
定される難点がある。However, in the configuration described above, the number of connector contacts 1 must be increased as the number of functions mounted on the meter 9 is increased, and the number of connectors 1 is often insufficient. For example, an instrument 9 having an 11-pin male connector contact 1 has 4 pins for input and output,
If five pins are used for communication and two pins are used for power supply, the number of pins is insufficient even if it is desired to mount an alarm function and a heater current measurement function. Therefore, the instrument 9 has a disadvantage that the number of mounted functions is limited according to the number of pins of the connector contacts of the terminal board 3 and the base 15 with terminals.

As described above, the shape becomes large, and it is necessary to replace the base with terminal 15 and the terminal board 3 in accordance with a change in the function of the instrument 9. The present invention has been made in order to solve such a conventional disadvantage, and the number of connecting means can be increased without increasing the number of connector contacts on the instrument side connected to the base with terminals. It is an object of the present invention to provide a case board with external connection terminals capable of increasing functions.
