The structure is such that the shorting plug is connected only to the terminal to be connected within the section, thereby making it possible to initialize at low cost and with high reliability.

[Industrial application field]

The present invention relates to a mechanism that performs initial settings at the end of a printed circuit board or a cable, and more specifically, to a mechanism that allows initial settings to be performed without using a setting printed circuit board or its terminals.

[Conventional technology]

Conventionally, the initial setting mechanism of the liquid supply printed circuit board was, for example, the fourth
As shown in the drawings and FIG. 5, a setting printed circuit board 61 is used when a connector 60 is connected to a connector 50 provided near the end of the printed circuit board 1 to perform initial settings.

In order to distinguish the connectors that are connected to each other, the connector provided on the printed circuit board 1 will be referred to as a first connector, and the connector to be connected to this will be referred to as a second connector.

This setting printed circuit board 61 includes a first connector 50.
The number of columns corresponding to the number of terminal pairs to be initialized is provided.

Each row has five through holes A to E and through hole A.
A pattern 62 connects the through hole B and the through hole D, and a pattern 63 connects the through hole B and the through hole E.

Among the through-holes A to E, through-hole A and through-hole B are for mounting the second connector 60, and therefore, through-hole A and through-hole B in each row are for mounting the second connector 60. 50 and a second connector 60
When connected, there is a one-to-one correspondence with each terminal 51 of the first connector 50.

Through-holes C-E are for mounting terminals 64 on each, and a shorting plug 65 for shorting is connected to terminal 64 of through-hole C and terminal 64 of through-hole D, or It can be connected to the terminal 64 of hole D and the terminal 64 of through hole E.

In FIG. 4, reference numeral 52 indicates claws for retaining the fitting provided elastically on both sides of the first connector 50, and reference numeral 66 indicates the claws 52 when mating.
These are recessed portions provided on both sides of the second connector 60 so that the two connectors 60 are engaged with each other.

screw 3t screw 1 - To initialize the printed circuit board 1 using this conventional technique, first connect the second connector 60 to the through holes A and through holes in each row of the setting printed circuit board 61. Then, it is mounted on the setting printed circuit board 61. FIG. 4 shows a state in which the second connector 60 is mounted in this manner.

Next, for each row of this setting printed circuit board 61,
According to the initial connection state of each terminal 51 of the corresponding first connector 50, the short plug 65 is connected to the terminal 64 of the through hole D and the terminal 64 of the through hole E, as shown by the arrow 77 in FIG. or to terminal 64 of through hole C and terminal 64 of through hole D.

Next, the second connector 60 mounted on the setting printed circuit board 61 in this manner is moved closer to the first connector 50 as shown by the arrow 78 and is fitted into the first connector 50 .

In this fitted state, the claw 52 of the first connector 50 is
