[Industrial application field]

The present invention relates to a switch switching device of a lever lock type toggle switch for automatically switching a lever lock type toggle switch.

[Conventional technology]

Generally, in a test of a commercialized electronic device, a switch incorporated in the product is turned on and off to test whether the internal electronic circuit is good or bad.

Conventionally, in an electronic device equipped with a lever lock type toggle switch, for example, as shown in FIG. 21, the switch switching lever 15 of the lever lock type toggle switch 13 connected to the circuit of the printed circuit board 11 is replaced by a finger 17 Then, the switch switching lever 15 is horizontally swung to the left and right in this pulled out state to test whether the internal electronic circuit is good or bad.

That is, in general, many toggle switches that are often used in electronic devices are simply in the two positions of on and off, and it is relatively easy to automate the switching operation, but with the lever lock type toggle switch 13, Since it is necessary to perform an on / off switching operation with the switch switching lever 15 pulled out forward, it is difficult to automate this operation, and conventionally, the switch switching operation has been performed manually.

[Problems to be solved by the device]

However, in this way, when performing the switch switching operation of the lever lock type toggle switch 13 manually,
Even if other test facilities or the front and rear processes are automated, this switching work becomes a bottleneck, and there is a problem that it is very difficult to reduce the number of work steps or cost.

Therefore, there has conventionally been a demand for a device capable of automatically switching the lever lock type toggle switch 13.

The present invention solves the above problems and provides a lever lock type toggle switch switch changing device which can automatically and surely switch a lever lock type toggle switch with a simple structure. The purpose is to provide.

[Means for Solving the Problems] A switch switching device for a lever lock type toggle switch according to the present invention is arranged in a direction perpendicular to the axial direction of the switch switching lever of a lever lock type toggle switch, and is long from the tip. A claw having a notch guide groove through which the base of the switch switching lever is inserted along the direction, and a tapered surface for pulling out the switch switching lever by movement along the notch guide groove of the switch switching lever A member, a support member for movably supporting the claw member in the axial direction of the switch switching lever, and a biasing force for urging the claw member in the axial direction of the switch switching lever and in the opposite direction to the switch body. The mechanism and the support member are moved in the direction perpendicular to the axial direction of the switch switching lever, and the notch guide groove of the pawl member is moved to the lever lock type toggle. And a switching movement mechanism that moves the support member in a direction orthogonal to the movement direction of the locking movement mechanism. It is a thing.

[Action]

In the present invention, first, the locking movement mechanism is activated,
The support member is moved in the direction perpendicular to the axial direction of the switch switching lever, whereby the tip of the notch guide groove of the pawl member is locked to the root of the switch switching lever.

After that, the locking moving mechanism is further moved, whereby the switch switching lever is relatively moved along the notch guide groove, and the switch switching lever is pulled out by the action of the tapered surface.

After that, the switching moving mechanism is operated, the supporting member is moved in a direction orthogonal to the moving direction of the locking moving mechanism,
As a result, the switch switching lever is swung left and right, and the switch is switched.

When the switch switching lever is swung to the left or right, the switch switching lever draws an arc around the root, so that the claw members at the left and right ends resist the urging force of the urging mechanism and the switch body side. Will be moved to.
