Description

[Detailed description of the invention] This invention inserts a contact holder into a case that allows axial sliding in one direction and the other direction from a neutral position,
With the sliding of the contact holder into one of the examples,
This relates to a sliding type switch that combines rotation and is configured to selectively close three types of load circuits by enabling reversible rotation at a fixed angle, the shaft of a contact holder, The purpose is to simplify the configuration by changing the shape of the shaft insertion hole on the case side through which the shaft is inserted.

In a switch with a variable resistor where the operating shaft of the variable resistor and the pull-button switch are the same, the operating shaft is rotated and the second switch is turned on and pulled to move the movable contact of the first switch in one direction. Slide it on and activate it.
During the ON operation, a malfunction prevention piece fixed to the operation shaft is brought into contact with a protrusion provided on the fixed side connection fitting in the rotational direction to disable the OFF operation of the first switch, and the push operation of the operation shaft turns the first switch off. The movable contact of the switch is turned off by sliding it in the other direction, at which time the malfunction prevention piece is moved in the axial direction so that it does not hit the protrusion in the rotational direction, and in this state, the operating shaft is rotated to turn it off. The second switch is turned off, and when the second switch is turned off, the malfunction prevention piece is axially aligned with the protrusion to disable the pulling operation of the operating shaft, that is, when the second switch is turned off, the second switch is turned off. The one in which the first switch was also prevented from turning on was released in 1973.
It is disclosed in Japanese Patent No. 9-82265.

However, in the above method, the operating shaft can only be slid into two positions (pull and push), and it is harmful to provide a neutral position in the axis movement direction. Since it is necessary to extract the variable resistance value of , it is also harmful to provide a neutral position in the rotation direction and then automatically return to the neutral position and rotate by an automatic return spring when you release your hand after the rotation operation.

The present invention is completely different from such a switch with a variable resistor,
A regulation that provides a neutral position in both the sliding and rotational directions of the shaft of the contact holder, and makes the shaft unrotatable in the axial neutral position and one sliding position, but rotatable in the other sliding position. is caused by the shape of the shaft and the shape of the shaft hole of the switch case through which the shaft passes, and furthermore, an axial neutral position holding spring and an automatic return spring to the rotational direction neutral position are provided, and the other shaft is When the user releases the hand after rotation occurs at the directional sliding position, the automatic return spring causes the rotation to return to the neutral position in the rotation direction, and the neutral retaining spring returns to the axial neutral position.

An embodiment of the present invention will be described with reference to the accompanying drawings. 1 is a square box-shaped case with insulating plates 2 and 3 fixed to the bottom and front surface, and the insulating plate 3 on the front side and the rear wall 4 of the case. Shaft insertion holes 6 and 7 are provided in the top wall 5, and a retaining groove 8 that is long in the front-rear direction is formed in the axial center of the inner surface of the top wall 5.

A power supply terminal 9 and a first load terminal 12 protrude from the left and right sides of the lower front surface of the insulating plate 3 on the front surface, and a second load terminal 14 and a third load terminal 16 protrude from the upper left and right sides.

The power supply terminal 9 is connected to a power supply side electrode plate 10 extending laterally below the inner surface of the insulating plate 3 and a power supply side electrode plate 11 extending in the front and back direction on the left side of the bottom insulating plate 2. Load terminal 12
A first load-side electrode plate 13 protruding to the left from the rear end of a lead extending in the front-rear direction on the right side of the insulating plate 2 is connected to the insulating plate 3. The left and right second and third load-side electrode plates 15 and 17 on the inside of the upper part are connected.

lf3 is a contact holder housed in the case 1, with a shaft 19 and a shaft 20 protruding concentrically from the center of the front and rear, and slidably inserted into the shaft insertion holes 6 and 7 described above, and a shaft 20 on the rear side. Forms a drum-shaped non-circular cross section 21 with a gentle V-shaped recess on both sides over a considerable length, and the rear end is parallel to the same height as the deepest part of the V-shaped recess. Cut off both sides to make a flat surface and cut off part 2.
form 2.

The contact holder 18 has a cylindrical shape and has a protrusion 2 on the top surface.
3 to form a circular groove 24 on both sides of the protrusion. On the lower surface of the waist, the bottom of the groove 24 is cut flat parallel to the insulating plate 2, and a through hole 25 is formed from the protrusion 23 to the smooth cut. A protrusion-resistant part 26 is provided on the front end surface, and connecting claws 27 are formed on both sides of the protrusion-resistant part 26.

A first contact 28 bent into a chopstick shape is fitted into the groove 24 from below, and one side of the contact is connected to the power supply side electrode plate 1.
1, and the other is provided with a contact 29 that can contact the first load-side electrode plate 13, and a presser 30 fitted in the through hole 25 is placed on the presser 30 in contact with the first contact 28. A spring 31 and a ball 32 are fitted, and the ball 32 is fitted into the engagement groove 8 of the case 1 to serve as an auxiliary rotation stopper for the contact holder 18.

In addition, a second contact 33, which is formed by folding the ring in a diagonal shape when viewed from the side, is fitted onto the front end surface and is latched by the engaging claw 27.
The lower contact 34 corresponds to the power supply side electrode plate 10, and the upper contact 35 corresponds to the second load side electrode plate 15 and the third load side electrode plate 1.
Correspond to the middle of 7.

Reference numeral 36 denotes a first neutral holding spring wound around the rear shaft 20, and each end of the first neutral holding spring is hung between the insulating plate 2 and the contact holder 18, so that it also acts as a neutral position return spring in the rotational direction.

A second neutral holding spring 37 is wound around the front shaft 19 inside the case 1 and brought into contact with the contact holder 18 and the insulating plate 3.

The shaft insertion hole 7 provided in the rear wall 4 of the case 1 is formed to have a similar shape to the non-circular cross section 21 of the shaft 20, thereby making it impossible for the shaft 20 and the contact holder 18 to rotate.

In the above embodiment, the contact holder 18 inserted into the case 1 is held at the neutral position shown in FIG. It passes through a shaft insertion hole 7 similar to the non-circular cross section 21 of the face wall 4, making rotation impossible.

Here, when the contact holder 18 is moved in the direction of arrow a against the elasticity of the first neutral holding spring 36 using the knob provided on the shaft 19, the contact 2 of the first co-shaft 28
9 causes a switch operation in which the electrode plate 9 contacts the power supply side electrode plate 11 and the first load side electrode plate 13.

Furthermore, when the knob of the shaft 19 is released, the action of the first and second neutral holding springs 36 and 37 automatically moves the shaft to the neutral position in the axial direction (
Return to Figure 1).

Further, when the contact holder 18 is moved from the neutral position in the direction of the arrow against the elasticity of the second neutral holding spring 37,
The non-circular section 21 of the shaft 20 comes out of the shaft insertion hole 7, the cut portion 22 is moved into the hole 7, and the cut portion 22 is inserted into the shaft insertion hole 7 as shown in FIG. When viewed from the front, it allows rotation of about 15° to 30° to the right or to the left as shown in Figure 9, and the left and right rotation angle is determined by the shaft insertion hole 7 and the shaft 20.
It is regulated within a certain range depending on the shape of the cut portion 22.

Therefore, when the contact holder 18 is moved in the direction of the arrow and then rotated to the right or left against the torsion spring action of the first neutral holding spring 36, the second contact 33 rotates together with the holder 18, and the contact 34 is rotated. Power supply side electrode plate 1
A switch operation is performed in which the contact 35 is brought into contact with the second load-side electrode plate 15 or the third load-side electrode plate 17 while remaining in contact with 0 (see FIG. 4).

When the shaft 19 is released, the contact holder 18 automatically returns to the neutral position in the rotational direction due to the elasticity of the first neutrality holding spring 36, which has a spring action for automatically returning the rotational direction, and the first and second neutrality holding springs 36 automatically return to the neutral position in the rotational direction. 36 and 37, it returns to the neutral position in the axial direction and becomes unable to rotate again (Fig. 1).

As clarified by the description of the embodiments, the present invention includes a case 1 in which a contact holder 18 is inserted, a shaft 19 at the front and rear of the holder 18 passed through shaft insertion holes 6 and 7 in the wall of the case, and a shaft. 20, when the halter 18 is in the neutral position or moved in one direction, the non-circular cross section 21 of the shaft 20 fits into the non-circular shaft insertion hole 7 inserted through the cross section. When the contact holder 18 is moved in the other direction, the shaft 20
Since the cutout part 22 provided following the non-circular cross-section part 21 moves into the non-circular shaft insertion hole 7 and is allowed to rotate at a certain angle, the sliding type switch is It is possible to easily provide both the functions of a sliding switch that causes a switch operation by sliding the contact holder so that it cannot rotate, and a rotary switch that causes a switch operation when the holder is allowed to rotate through a certain angle. Moreover, the shaft 20 is provided with a neutral position in both the sliding force direction and the rotational direction, so that the first neutrality holding spring that acts on the contact holder in the axial direction and the second neutrality holding spring that acts on the contact holder in the rotational direction are opposite in the axial direction. Since it is provided so that it acts in the axial direction, when the shaft 19 is released, even if the shaft is sliding or rotating on sliding, it can quickly return to the neutral position in the axial direction. With this, it is possible to rationally combine the functions of both a sliding switch and a rotary switch.
