Description

[Detailed Description of the Invention] The present invention relates to a sliding switch that is operated by the movement of a sliding member.

As shown in Fig. 1, a conventional sliding switch has a sliding body 1'.
one part 1a' is rotatably supported on the case body 2',
Attach the operating rod 3' to the other part of the sliding body 1', and
By operating the sliding body 1', one part 1 of the sliding body 1' is
It has a configuration in which it swings around a' as a fulcrum and operates a switch on a contact mechanism (not shown) disposed opposite to the sliding body 1' and the case body 2'. In order to widen the arrangement space and obtain a long operating stroke of the contact mechanism, it is necessary to extend one portion 1a', which serves as a fulcrum of the sliding body 1', resulting in a drawback that the switch as a whole becomes large.

Therefore, the present invention solves the above-mentioned drawbacks, devises a sliding switch whose overall size is small, and which can be operated smoothly. Explain in detail.

1 is a sliding body, which is housed inside the case body.

The case body 2 and the board 5 constitute a switch case, and an arcuate orbit line X centered on an arbitrary point A is located outside the switch case and extends in the same direction as the inner bottom surface of the case body 2.1. Two guide grooves 21 arranged in parallel along X2.
22 is formed.

Further, the groove shape of the guide grooves 21 and 22 is in the shape of a square cross section as shown in FIG.

The sliding body 1 is movably housed in the case body 2, and has hemispherical holes 11.12 at positions facing the two guide grooves 21.22 of the case body 2.
Three spheres 4, for example stay balls, which engage in guide grooves 21, 22 of the case body 2 are inserted into the housing 2.

More specifically, the three stay balls 4 are:
As shown in FIG.
are arranged at the bottom of the sliding body 1 to engage with the guide grooves 21, respectively.

In other words, the sliding body 1 is inserted into the guide groove 21.2 of the case body 2.
The structure is such that the second part is supported at three points by three stay balls 4.

Furthermore, since the groove shape of the guide grooves 21 and 22 is configured to have a V-shaped cross section, it has good sliding properties when moving along an arcuate track within the case body 2, and in the normal direction of the arcuate track. has a support structure for the sliding body 1 without play.

Reference numeral 3 denotes an operating rod, which is attached to the sliding body 1 by a pin 9 in order to slide the sliding body 1 in the forward direction of arrow C or arrow C', that is, in the horizontal direction.

Reference numeral 5 designates a plywood board having a fixed contact 6, which is fitted and bonded to the edge 23 of the case body 2 so that the sliding body 1 is interposed between the plywood and the inner bottom surface of the case body 2.

Reference numeral 7 denotes a contact mechanism, which is composed of a fixed contact 6 provided on the substrate 5 and a movable contact 8 provided on the upper surface of the sliding body 1 to correspond to the fixed contact 6, and is operated as a switch by the movement of the sliding body 1. It is something.

14 is a spring, 15 is a stay ball, and 16 is a moderation plate, and the stay ball 15 is connected to the spring 14.
The moderation plate 16 is inserted into a hole 13 drilled in the front surface of the sliding body 1 through the switch, and the moderation plate 16 is disposed inside the case body 2 facing the hole 13 of the sliding body 1 to constitute a moderation mechanism of the switch. .

Note that the moderation plate 16 has three valley-shaped portions 16 that engage the stay balls 15 in order to lock the movement of the sliding body 1 in three positions.
It has a.

An insertion hole for the operating rod 3 is provided on the front surface of the case body 2.

Next, the operation will be explained.

Now, when the operating rod 3 and the sliding body 1 are in the 9 position shown in FIG. The sliding body 1 and the operating rod 3 roll in a circular orbit centered on an arbitrary point A from position E to position 1. The switch mechanism 7 operates as a switch.

More specifically, since the sliding body 1 is supported via three stay balls 4 in the guide grooves 21 and 22 of the cross-section shaped like a square mark provided on the inner bottom surface of the case body 2, the sliding body 1 is supported through three stay balls 4. The moving body 1 is smoothly moved along an arcuate trajectory while always remaining parallel to the bottom surface of the case body 2.

When operating the operating rod 3 in the horizontal direction, that is, in the forward direction of arrow C or C', a sense of moderation is given by the moderation mechanism, and the sliding body 1 is locked at three positions, E and F.

Note that the switch mechanism 7 is also operated by providing the operating rod 3 in the up and down direction B-B'.

The present invention consists of a case body that has two arc-shaped guide grooves on the inner bottom surface and an insertion hole for the operating rod that passes through the front surface;
a sliding body having a rolling element that fits in the guide groove at the bottom and a movable contact fixed to the top surface; a moderation plate interposed between the front surface of the sliding body and the inner wall of the case body; and the sliding body. A sliding switch is characterized in that it is composed of an operating rod fixed to the movable contact, and a substrate fixed to the fixed contact that contacts the movable contact and covered by the case body, which has the following unique effects. play.

(a) Since the sliding body moves using an arbitrary point outside the switch case as a fulcrum, there is no need to extend the sliding body and the switch case to the moving fulcrum of the sliding body, and the structure is small and simple. We can provide sliding switches.

(b) A sphere is interposed between the sliding surface of the sliding body and the inner bottom surface of the switch case, and when the sliding body moves, the sphere rolls, so switch operation with the operating lever is smooth, etc. has.

(c) A movable contact on the top surface of the sliding body, a sphere on the bottom surface,
In addition, moderation mechanisms are distributed on each side of the front surface, making it easy to downsize the sliding body in terms of design.
This also contributes to miniaturization of the sliding switch.
