## Abstract

A device to fasten a power supply connector unit 18 to a solenoid valve assembly 1 comprising multiple solenoid valves 2. The fastening device has a side plate 4 having a vertical first fitting surface 21a and a horizontal second fitting surface 21b, two pairs of positioning recesses 22a and 22b and two pairs of engaging recesses 23a and 23b on the two fitting surfaces, two each projections 29 and hooks 30 on the connector unit 18, and an opening 20 to pass lead wires extending over the two fitting surfaces.

## Claims

### Claim 1

In means for attaching a connector unit supplying power to individual solenoid valves to a solenoid valve assembly comprising multiple solenoid valves, the improvement which comprises:
a side plate disposed at one end of the solenoid valve assembly having a vertical first fitting surface and a second fitting surface extending horizontally from the first fitting surface for fastening the connector unit, an opening to pass a lead wire extending over the two fitting surfaces, and at least one engaging recess provided in each of the two fitting surfaces to fasten the connector unit in position; and
the connector unit having at least one hook adapted to be selectively and elastically engaged with the engaging recesses on each fitting surface to permit selective fastening of the connector unit in an upright or a horizontal position.

### Claim 2 (depends on 1)

The improvement according to claim 1, in which at least one positioning recess to determine the fastening position of the connector unit is provided in each of the two fitting surfaces of the side plate and at least one projection to engage with the positioning recess is provided on the connector unit.

### Claim 3 (depends on 1, 2)

The improvement according to claim 1 or 2, in which the connector unit comprises a first connector leading to the individual solenoid valves and a holder to hold the first connector, with the holder having said hook or both of said hook and projection.

### Claim 4 (depends on 2)

The improvement according to claim 2, in which two each positioning and engaging recesses are symmetrically provided on each of the two fitting surfaces of the side plate and two each projections and hooks are symmetrically provided on the connector unit.

### Claim 5 (depends on 4)

The improvement according to claim 4, in which the connector unit has a first connector leading to the individual solenoid valves and a holder to hold the first connector, with the holder having said two each projections and hooks.

### Claim 6 (depends on 5)

The improvement according to claim 5, in which the holder is shaped like a long box with an open top and side, with the first connector mounted on the top thereof, the lead wires from the individual solenoid valves connected to the first connector through the open side, two projections formed at the bottom of the holder, and said hooks are provided on the elastic part formed at both ends of the length of the holder.
