Description

The present invention relates to a conduction switching mechanism, which is in the first conduction state, particularly when no external force is always applied, and when an external force is applied, the second conduction state is established and when the external force disappears, the second conduction state is automatically obtained. The present invention relates to a device for switching a circuit to a different conductive state so as to return to the conductive state of 1.

In the conventional conduction switching mechanism, the conduction state can be changed by applying an external force to the button, but in order to return the conduction switching mechanism to the original conduction state, it is usually necessary to separately apply an external force to the button.

In such a conduction switching mechanism, one set of fixed terminals and one set of movable terminals are arranged, and the movable terminal set is slidably connected to the movable terminal set in order to switch to a different conduction state. Such a conduction switching mechanism usually uses a spring component to apply a resilience to the movable terminal set in order to automatically recover the movable terminal set. However, in the process of sliding the movable terminal set, an error due to vibration is likely to occur, which causes a problem that the continuity accuracy is poor. Further, since the structure of the movable terminal set is usually manufactured so as to weld a plurality of metal parts and the structure is complicated, the above-mentioned method is troublesome to manufacture and tends to cause an error due to manufacturing.

The front end portion of the lever fulcrum portion 73 abuts on the foundation frame fulcrum 122 of the foundation frame 10b. The lever 70 in the present embodiment may be made of a hard material such as a metal plate, but the present invention is not limited thereto.

One end of the spring component 60 is connected to a part of the lever 70, and the other end of the spring component 60 is connected to a part of the movable terminal module 50. One end of the spring component 60 is connected to the union suspension hole 555.

As shown in FIGS. 6 to 8, FIGS. 6 to 8 are a three-dimensional combination diagram, a top view, and a side surface showing a first conduction state of the conduction switching mechanism (cover and operation pusher are removed) according to the present invention, respectively. It is a figure. The assembly process of the present invention is as follows. First, both ends of the spring component 60 are connected to the lever 70 and the movable terminal module 50, respectively. Then, the rear end portion of the movable terminal module 50, that is, the first terminal fulcrum portion 522a of the first movable terminal 5a and the second terminal fulcrum portion 522b of the second movable terminal 5b are always connected to the fulcrum of the terminal 33. Engage with bearing 333. Further, the first path terminal 31 is clamped so that the rear end portion of the movable terminal module 50, that is, the first movable contact 54a and the second movable contact 54b slide downward. Then, the rear end portion of the lever 70, that is, the stress portion 72 of the lever 70 is slightly pulled backward so that the lever fulcrum portion 73 at the center of the lever 70 abuts on the base frame fulcrum 122 of the holder 12.

The method for realizing the conduction switching mechanism according to the present invention will be schematically described as follows. When the operating pusher 20 is pushed down by an external force, the bottom of the operating pusher 20 presses one end of the lever 70 to move the movable terminal module 50 and pulls the spring component 60 to store the elastic force. There is. The slidable end of the movable terminal module 50 is slidably freely connected to the conductive portion of the fixed terminal set 30 so as to be in a certain conductive state. When the external force disappears, the operation pusher 20 and the lever 70 apply the elastic force of the spring component 60 to return to the state before the external force was applied, and at the same time, the movable terminal module 50 is interlocked with the movable terminal module 50. The slidable end is freely slidably connected to another conductive portion of the fixed terminal set 30 to bring it into another conductive state.

As shown in FIGS. 6 and 8, in the first conductive state of the conduction switching mechanism according to the present invention, the first movable contact 54a of the first movable terminal 5a and the second movable terminal 5b of the second movable terminal 5b are movable. The contact 54b is located at a higher position, that is, is connected to the first sliding contact portion 311 of the first path terminal 31 and the second sliding contact portion 321 of the second path terminal 32, respectively.

Incidentally, in the present embodiment, a pair of locking portions 57c protruding upward are arranged at the rear end portion of the insulating main body portion 51c of the insulating component 5c in the movable terminal module 50, and the pair of locking portions 57c are arranged. Is close to the first terminal fulcrum portion 522a and the second terminal fulcrum portion 522b, respectively. The position of the locking portion 57c corresponds to the position of the constant connection terminal 33. In the first conduction state of FIGS. 6 and 8, the locking portion 57c may abut on the constant connection terminal 33. As a result, the angle at which the movable terminal module 50 is inverted backward (that is, inverted in the clockwise direction in FIG. 8) is limited, and the first movable contact 54a and the second movable contact 54b are unexpectedly first. It comes off from the path terminal 31 of.

In the present embodiment, in the situation according to FIGS. 6 and 8, no external force is applied to the conduction switching mechanism 1. In this embodiment, it is defined as the first conduction state. When the lever 70 is not pushed down by the operating pusher 20 by an external force, the lever 70 receives a tensile force from the spring component 60 with the front end of the lever fulcrum 73 as a fulcrum, and the stress portion 72 of the lever 70 is pulled upward to move. It comes close to the terminal module 50. The movable terminal module 50 is driven by the tensile force of the spring component 60 with the line consisting of the first terminal fulcrum portion 522a of the first movable terminal 5a and the second terminal fulcrum portion 522b of the second movable terminal 5b as a fulcrum. , The position of the first movable contact 54a and the second movable contact 54b (the second movable contact 54b is not shown in FIG. 9) is higher, and the first sliding contact portion like the first path terminal 31 It comes to connect to 311. In other words, in the first conduction state, the always-on connection terminal 33 is electrically connected to the first path terminal 31 by the movable terminal module 50, and becomes a first passage (pathway).

8 is referred to with FIGS. 2 and 3. Two guide protrusions 512c project further from the bottom of the insulating component 5c of the movable terminal module 50. Each guide protrusion 512c is formed in a substantially triangular prism. As shown in FIG. 10, the guide protrusion 512c positions the insulating component 5c on the holder 12 of the base frame 10b, that is, the two outermost side walls of the holder 12 when the movable terminal module 50 moves downward. The movable terminal module 50 can be guided to the above.

When the conduction switching mechanism 1 receives an external force, as shown in FIG. 9, the external force is applied to the operation pusher 20 and changes to the state shown in FIG. In this embodiment, it may be defined as a second conduction state. The operation pusher 20 pushes down the stress portion 72 at the rear end of the lever 70 to rotate the lever 70 in the clockwise direction of FIG. 9 and interlocks the movable terminal module 50. The movable terminal module 50 rotates in the counterclockwise direction of FIG. 9 with the first terminal fulcrum portion 522a and the second terminal fulcrum portion 522b as fulcrums. The first movable contact 54a and the second movable contact 54b in the movable terminal module 50 move downward and are connected to the second sliding contact portion 321 of the second path terminal 32 to enter the second conduction state. To do. In the process, the spring component 60 is pulled to store elastic force. In other words, in the second conduction state, the constant connection terminal 33 is electrically connected to the second path terminal 32 by the movable terminal module 50, and is formed in the second passage (pathway).

When the external force disappears, the state of FIG. 10 returns to the state of FIG. 9, and the operation pusher 20 and the lever 70 return to the state before receiving the external force by the elastic force of the spring component 60. In other words, the stress portion 72 of the lever 70 reverses upward, that is, moves in the counterclockwise direction. The spring component 60 simultaneously links the movable terminal module 50. The movable terminal module 50 moves in an upward direction (clockwise direction) with the first terminal fulcrum portion 522a and the second terminal fulcrum portion 522b as fulcrums. The first movable contact 54a and the second movable contact 54b at the front end of the movable terminal module 50 are slidably connected to the first sliding contact portion 311 of the first path terminal 31, as shown in FIG. Then, it returns to the first conduction state.

In the features and effects of the present invention, the first movable terminal 5a and the second movable terminal 5b in the movable terminal module 50 are each configured to be integrally molded by press working. The terminal fulcrum, the movable contact, and the main body are configured to extend from the same plane, and it is not necessary to press them separately before welding. The first movable terminal 5a and the second movable terminal 5b in the present embodiment are preferably manufactured of a copper alloy or other high-strength conductive material. The terminal fulcrum, the movable contact, and the main body are configured to extend from the same plane, and the movable contact is always electrically connected to the fixed terminal set, and the terminal fulcrum is attached to the fulcrum bearing 333. Since it abuts, it can have sufficient elastic force. The integrally molded structure of two movable terminals in the present embodiment by pressing has excellent accuracy, and cumulative tolerances are obtained by separately manufacturing two or more members and then combining them in order to manufacture one movable terminal. Can be avoided and the overall strength can be increased.
