Description

Double-control switch

Technical Field

The application relates to the technical field of electric appliances, in particular to a double-control switch.

Background

This section provides background information related to the present application and does not necessarily constitute prior art.

The double-control switch is a switch with two normally open and normally closed contacts, and the on-off action of the switch can be triggered by pressing one of the two contacts. The basic structure of the double-control switch comprises three connecting terminals, wherein one input connecting terminal and two output connecting terminals are arranged, a moving contact with two contacts is connected with the input connecting terminal, two fixed contacts are respectively connected with the two output connecting terminals, and a switch key assembly controls the two contacts of the moving contact to respectively perform closing/breaking switching between the two fixed contacts. For a double-control switch in a wall switch, three major demand trends are faced: the technical improvements made from three requirements of large-current control, multi-line access and threadless wiring need to increase the volume of the double-control switch, particularly the thickness of the double-control switch. However, the wire slots reserved on the wall for installing the double-control switch are standardized, and the space of the wire slots is fixed and limited. In addition, the three requirements also cause the problem that the wire occupies a large amount of the slot space, for example, compared with the prior art that a thick wire with a 4-square-millimeter access of a double-line (2 incoming wires plus 4 outgoing wires) occupies 8 times of the slot space of a thin wire with a 1-square-millimeter diameter of a single-line (1 incoming wire plus 2 outgoing wires), the problem that the slot space is not enough is highlighted. The problem that the space of a wire slot is insufficient is solved, a method for reducing the volume of a wire cannot be adopted, and only a method for reducing the volume of a double-control switch can be adopted, so that the thickness reduction design of the double-control switch is the most urgent and challenging technical problem in the production of the current double-control switch product.

The reduced thickness design of the bi-control switch is challenging for a number of reasons, the main one being that there are many design conflicts in the art. Firstly, the increase of rated current requires the increase of the breaking distance of the contact and the insulation distance between the guide pieces, and the increase of the distances is in contradiction with the design of thickness reduction. Secondly, the volume of each connecting terminal needs to be increased for multi-line access and thick lead access, and the increase of the volume is also contradictory to the design of thickness reduction. And once again, the thread-free quick connection and disconnection requires the increase of operation space for connecting and disconnecting the thread and accommodating the intervention of fingers or tools, and the increase of the space is also contradictory to the design of thickness reduction. For the above reasons, the problem of large volume of the dual-control switch in the prior art is still very prominent, and it is impossible to obtain the ideal effect without optimizing the overall design and the structural design.

Moreover, the double-control switch provided by the prior art has various components and a complex structure, so that the adverse risk of the switch product is easily increased, and the light and thin development of the switch is not facilitated.

As shown in fig. 9a and 9b, the pressing motion of the button 500 is converted into the rotation of the transition piece 601, the rotation of the transition piece 601 is converted into the pushing of the push rod 602 to the swing link 700, and the rotation of the swing link 700 is converted into the rotation of the trigger plate 902, so that the on-off switching of the dual-control switch is realized through the process. In this process, a small stroke pressing motion of the button 500 can be converted into a large stroke motion of the swing link driving part 600. The conversion from the small stroke to the large stroke is beneficial to reducing the installation height of the key 500 and the light and thin development of the double-control switch.

The pressing force from the button 500 can be rapidly and accurately transmitted to the swing rod driving element 600 to drive the transition piece 601 to rotate, but since the on-off of the double-control switch is finally triggered by the trigger plate 902 rotating around the second fulcrum, the rotating angle of the transition piece 601 does not need to be too large, the depth of the hole 302 can be correspondingly reduced, and the double-control switch is favorably developed in a light and thin manner.

The push rod 602 pushes the swing rod 700 to drive the rotating structure of the trigger plate 902, so that the accommodating space of the rear seat 400 can be reasonably utilized, and the light and thin development of the double-control switch is facilitated.

Further, the swing link 700 drives the trigger plate 902 to rotate through the elastic portion 901, and the contact conversion between the first contact 903 and the second contact 805 and the third contact 806 is switched, so that the on-off trigger of the dual-control switch is more accurate and efficient. The first contact 903 is arranged between the second contact 805 and the third contact 806, and the on-off trigger effect is improved.

In the dual control switch provided in the embodiment of the present application, the elastic portion 901 may be designed in various structural forms as long as the compression direction of the elastic portion 901 is along the length direction of the swing link 700. The swing rod driving piece 600 is manufactured in an integrated forming mode, the swing rod driving piece is of an integrated structure, assembly is facilitated, the assembly process of the double-control switch is simplified, and the swing rod driving piece 600 is long in service life. The rocker arm drive 600 may be made of, for example, a Polycarbonate (PC) material, which has high strength and high flexibility. The width of the transition piece 601 of the swing link driving member 600 is greater than the width of the middle portion of the swing link driving member 600, so that the contact area between the button 500 and the swing link driving member 600 is increased, and the transmission of the pressing force by the swing link driving member 600 is more flexible, smooth and efficient.

In the dual-control switch provided by this embodiment, when the button 500 is pressed to rotate one end by 1.8 °, the transition piece 601 of the corresponding swing link driving member 600 rotates by 1.8 °, and meanwhile, the corresponding push rod 602 moves by 0.7mm in the lateral direction, so as to drive the swing link 700 to rotate by 7 ° to implement on-off switching.
