Description

[Detailed Description of the Invention] The present invention relates to a holding device for holding electrical components such as temperature fuses, etc., which facilitates the installation work when attaching a pair of holding fittings for holding electrical components to an insulating plate. It is an object of the present invention to provide a structure in which the mounting pitch of electrical components held by a pair of holding fittings does not change.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

In Figures 1 and 2, 1 is the wind tunnel of the hot air generator;
Inside this wind tunnel 1 is a ventilation passage 2 through which warm air passes.

Reference numeral 3 denotes a temperature fuse that operates by sensing an abnormal temperature within the ventilation passage 2, and this temperature fuse 3 is installed in the wind tunnel 1 so that it can be attached and detached relatively easily.

Reference numeral 4 denotes an insulating plate detachably attached to the outer bottom of the wind tunnel 1 with screws 5, and a pair of holding metal fittings 6, 6' having a substantially U-shape are attached to this insulating plate 4.

Further, the pair of holding fittings 6, 6' are provided with screw holes 7, 7' on the upper side for attaching the temperature fuse 3, and these screw holes 7, 7'
The temperature fuse 3 is attached by screwing in the screw 9.9' through the washer 8.8'.

:0.10' is a threaded hole for mounting to the insulating plate 4 provided on the lower side of the holding metal fittings 6, 6', and this threaded hole 10°10' is the threaded hole for mounting the temperature fuse 7, 7'. Holes 11.11' are provided in the insulating plate 4 in correspondence with the screw holes 10.10' which are provided on the same center line.

12.12' is a bent part that is integrally bent downward on the lower side of the holding fittings 6, 6'.
Square holes 13, 13' are provided in the insulating plate 4 corresponding to the square holes 13, 13'.

When attaching the pair of holding fittings 6, 6' to the insulating plate 4, the bent portions 12° 12 of the holding fittings 6, 6'
After fitting the screws 14.14' into the square holes 13, 13' of the insulating plate 4, insert the screws 14.14' through the holes 11.11' of the insulating plate 4 into the tapped holes 10.10 of the holding fitting 6°6'. The holding fittings 6, 6' are attached to the insulating plate 4 by screwing them into the insulating plates 4.

In this case, the bent portions 12, 12' of the holding fittings 6, 6'
are fitted into the square holes 13.13' of the insulating plate 4, so the screws 14, 14' are inserted into the tapped holes 10.10 of the holding fittings 6, 6'.
When screwed in, the holding fittings 6, 6' do not rotate, and as a result, the screwing operation can be performed extremely easily.

In addition, the threaded holes 10 and 10 provided on the lower side of the holding fittings 6 and 6'
' is provided so that it is on the same center line as the temperature fuse screw holes 7, 7', so even if the holding fittings 6, 6' rotate due to a slight gap, the mounting pitch P of the temperature fuse 3 will be It never changes.

Further, the bent portions 12.12' provided on the lower sides of the holding fittings 6, 6' are made to protrude downward from the square holes 13, 13' of the insulating plate 4, and any holes 15. By shaping 15', it can also be used as a lead terminal plate to which lead wires (not shown) are connected.

As described above, according to the present invention, a bent portion is provided at the lower side of a pair of approximately U-shaped holding fittings that hold electrical components,
Since this bent part is fitted into a hole formed in the insulating plate to prevent rotation, the pair of holding fittings will not rotate when attached to the insulating plate. , the installation work is extremely easy.

In addition, the holes for attaching electrical components and the holes for attaching to the insulating plate on the upper and lower sides of the holding bracket are provided so that they are on the same center line, so there is a slight gap between the holes for attaching the holding bracket. Even if it rotates, the mounting pitch of the electrical parts will not change, and various other practical effects can be achieved.
