Description

Switch {switch}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch, and more particularly, to a switch in which on / off states of a power supply line are stably switched to improve operation reliability.

Generally, electrical switches are essential unless they are unnecessary for electrical appliances such as electrical appliances, electrical devices, and electrical equipment. Among the known switches, push-button switches and rocker switches are most widely used.

Here, the rocker switch generally comprises a rocker member that can be toggled between at least two optional stable operating positions corresponding to different optional operating modes.

And, the pushbutton switch generally includes a pushbutton that is linearly driven by a simple linear motion, such as by releasing the pushbutton after it is released.

Further, a push-button drive type switch including a rocker-type switching mechanism has already been disclosed.

On the other hand, the conventional push button switch includes a push button for pushing, a switching mechanism for switching the connection between the circuits, and a drive converting means for converting the operation of the push button into an operation suitable for mode conversion of the switching mechanism.

In this case, the drive converting means includes a rocker member connected to the switching mechanism and providing a lateral driving force of the switching mechanism, and a slide operation member provided at a lower portion of the push button and elastically moved in the lateral direction.

A pair of wedge-shaped protruding heads are provided on both sides of the upper surface of the rocker member, and a pair of pressing protrusions corresponding to the connection protrusions are provided on both sides of the lower surface of the slide operation member.

In the conventional push button switch, when the push button is lowered, one of the connection protrusions of the slide operation member is slid along the inner surface of one of the protrusion heads to the other protrusion head side, and the other protrusion head The mode conversion of the switching mechanism is performed by a complicated process in which the rocker member is rotated to one side by being pressed downward.

Accordingly, only when the distance between the projecting heads and the rotation angle of the rocker member is accurately designed, the mode switching of the switching mechanism can be performed, and it is difficult to change the overall structure of the switch.

In addition, even when the rotation angle of the rocker member is slightly shifted during mode conversion of the switching mechanism, the locking protrusion of the slide operation member is caught between the protruding heads of the rocker member and the rotation of the rocker member or slide movement of the slide operation member becomes impossible, There was a problem that it caused discomfort.

The slide operation portion 45 is formed with a gradient pushing surface portion 46 which is inserted into the guide groove portion 44 and is alternately brought into contact with the pressing protrusion 33 at both ends of a body portion 46 slidable in both lateral directions along the inner surface 47 are preferably staggered. In this case, the term " both directions " means a direction corresponding to the power source side connection line and the load side connection line.

In detail, when the button 30 is depressed, any one of the pair of the pressing protrusions 33 that are lowered is slid along the inclined surface of the gradient pressing surface 47 disposed adjacent to each other, Thereby pressing one side of the portion 40. Accordingly, when the other side of the operation knob portion 40 is lifted and seesawed, the fixed protruding portion 43 pivots to press the movable elastic terminal 80.

When the movable elastic terminal 80 is seated in the direction opposite to the operation knob portion 40 by the pressing force of the fixing protrusion 43 and the contact ends 72 and 82 are selectively contacted, It can be turned on or off.

At this time, when the end portion of the pressing protrusion 33, which is substantially fixed to the lower surface of the button portion 30 and vertically moved, comes into close contact with the inclined surface of the gradient pressing surface portion 47, the slide operation portion 45 Is pressed while being slid in the outward direction. At this time, when the depressing operation of the button unit 30 is released, the returning elastic means 48 is attached to the receiving portion 46b formed inside the body portion 46 so that the slide operation portion 45 is returned to the initial position It is preferable that it is inherent.

A slide restricting groove 44a is formed along the longitudinal direction on the inner surface of the guide groove 44. A guide protrusion 46a for guiding movement along the slide restricting groove 44a is formed in the slide operation portion 45, Is preferable. Accordingly, since the slide movement of the slide operation part 45 is limited only in the both side directions of the guide slot part 44, the operation reliability can be remarkably improved. Further, since the slide operation portion 45 is substantially integrally fastened to the operation knob portion 40, the structure of the switch 100 can be simplified, and the assembly can be easily performed. Thus, the productivity can be remarkably improved.

4A, when the button portion 30 is pressed so that one side of the upper surface of the operation knob portion 40 is lowered, the end portion of the fixing protrusion 43a are pendulum-moved in the other direction of the case part 10. [

When the movable groove portion 84 is pressed corresponding to the pendulum moving radius of the fixed projection end portion 43a, the movable elastic terminal 80 moves the seesaw groove portion 81 supported by the seesupport portion 63, And the seesaw movement is performed such that the elastic portion 83 side is raised. At this time, the first contact end portion 82 formed on the other side of the seesaw groove portion 81 is lowered and comes into contact with the second contact end portion 72 of the switching terminal 70, so that the switch 100 is turned ON ) State so that current can be passed through the electric device.

At this time, when the switch 100 is ON, the end of the pressing protrusion 33 protruding to the other side of the lower surface of the button cover 31 and the pressing surface 33 protruding from the other side of the slide operating portion 45 And the outer end portions 47a of the outer side walls 47 are disposed adjacent to each other. At this time, a later-described bulb surface 33a is formed at an end of the pressing protrusion 33, and the bulb surface 33a and the gradient pressure surface portion 47 may be arranged to correspond to each other.

4B, when the button portion 30 is pressed again in the ON state of the switch 100, the other pressing projection 33 of the button portion 30 is lowered, The pressing surface portion 47 is pressed.

The pushing protrusions 33 may be formed at the outer ends of the pushing protrusions 33 so that the pushing protrusions 33 are inclined upwardly toward both sides of the pushing portion 30. The slope pressing surface 47 is in contact with the sphere rear surface 33a of the pressing protrusion 33 which is lowered when the button 30 is depressed, It is preferable to be inclined upwards in both directions.

Accordingly, when the pressing protrusion 33 is lowered when the button portion 30 is pressed, the sphere rear surface 33a and the inclined surface s of the gradient pressing surface 47 can be closely contacted with each other. The pressing projection 33 is slidingly moved from the outer end portion 47a of the gradient pressing surface portion 47 toward the inner end portion 47b to press the other side of the operation knob portion 40.

When the button 30 is pushed, the slide operation portion 45 is pivoted such that the outer end portion 47a of the gradient pressing surface portion 47 is aligned with the upper end of the sphere rear surface 33a of the pressing projection 33 Slide can be moved. At this time, since the pressing protrusion 33 is substantially fixed to the bottom portion of the button cover 31 and is moved in the vertical direction, the slide operation portion 45 is slid in the outward direction along the guide groove portion 44 do. When the slide operating part 45 is moved outwardly, the return resilient means 48 interposed between the inner surface of the receiving groove 46b and the partitioning projection 46b can be pressed and contracted.

The pressing projection 33 stably contacts the inclined surface s of the gradient pressing surface portion 47 formed so as to correspond to the spherical surface 33a of the end portion so as to be slidably moved, The operation reliability can be remarkably improved because the knob portion 40 is pressed.

The pressing support portion 47b may be formed at the inner end portion 47b of the gradient pressurizing surface portion 47 so that the force that the sliding movement of the end of the pressing protrusion 33 is restrained by the pressing force. That is, when the end portion of the pressing projection 33, which is slidably and slidably moved along the inclined plane s of the gradient pressing surface 47, is seated on the pressing support portion 47b, A pressing force can be applied directly to the operation knob portion 40. [

At this time, when the slide operation part 45 is slid outwardly along the guide groove part 44, the pressing position at which the pressing force is applied during the pressing operation of the button part 30 is further moved from the hinge engagement part 23 And can be moved outward. Since the pressing force is applied to the inclined surface s of the gradient pressurizing surface portion 37 extending obliquely outwardly at both ends of the slide operation portion 45, 100 can be improved.

4C, when the operation knob portion 40 is seated about the hinge engaging portion 23, the operation knob portion 40 is pressed against the other side portion of the operation knob portion 40, The end portions 43a of the fixing protrusions are pendulum-shaped in one direction of the case 10. As shown in FIG.

When the movable groove portion 84 is pressed in correspondence with the pendulum moving radius of the fixed projection end portion 43a, the movable elastic terminal 80 contacts the operation knob portion 40 The seesaw motion is performed in the opposite direction. The elastic portion 83 is lowered and the first contact end portion 82 is raised and separated from the second contact end portion 72 so that the switch 100 is turned off, The current flowing into the device may be cut off.

At this time, even if the pushing operation of the button portion 30 is released, the separated state between the movable groove portion 84 and the seesaw groove portion 81 can be elastically supported by the elastic restoring force of the elastic portion 83. Accordingly, the fixing protrusion 43 is prevented from being pendulously moved arbitrarily regardless of the pressing operation of the button portion 30, so that the energization or disconnection of the current can be stably maintained. Of course, as the case may be, the fixing protrusion may be provided with an elastic structure to elastically support the movable elastic terminal, and such modifications are within the scope of the present invention.

When the pushing operation of the button unit 30 is released, the button unit 30 is elastically returned to its original position by the elastic restoring force of the elastic means 34, (33) are separated from each other. Accordingly, the slide operation portion 45 can also be returned to the initial position by the elastic restoring force of the return resilient means 48. As a result, even when the button portion 30 is continuously pressed, the pair of pressing surfaces 47 are provided at positions corresponding to the pair of pressing protrusions 33, The operation reliability can be remarkably improved by being driven stably even in the continuous pressing operation.

As a result, the switch 100 according to the present invention is configured such that, when the button portion 30 is pressed, the spherical surface 33a of the pressing projection 33 is substantially inclined to the inclined surface s of the gradient pressing surface 47 And are formed so as to correspond to each other so as to slide in a surface contact manner in a wrapped form. Accordingly, the pressing force for the seesaw motion of the operation knob portion 40 is stably transmitted, and the operation reliability can be remarkably improved.

When the button portion 30 is depressed, the slide operation portion 45 is slid outwardly so that the pressing position between the pressing protrusion 33 and the gradient pressing surface portion 47 becomes the hinge coupling portion 23 ), It is possible to perform an easy operation with less force by the leverage action, and the operation feeling can be improved.
