In addition, the contact connection method based on the sliding structure has a problem of insufficient response speed. In some applications requiring high-speed switching, such as signal modulation and high-frequency communication, the switch of this configuration may not meet the requirement for fast response.

Detailed Description
In order to describe the technical content, the constructional features, the achieved objects and effects of the present utility model in detail, the following description is made in connection with the embodiments and the accompanying drawings.
The present embodiment discloses a micro-mechanical switch for circuit switching, for example, switching a connected state of a target circuit to an disconnected state, or switching from a receiving first signal state to a receiving second signal state. As shown in fig. 1 to 3, the micro-mechanical switch comprises a support base 1 and a movable base 2, wherein the movable base 2 can make a reciprocating motion close to or far from the support base 1 along a first direction F1. In the direction shown in figure 1, the movable seat 2 can move up and down relative to the supporting base 1 under the action of trigger force.
The support base 1 is provided with a first pin J1, a second pin J2, a third pin J3 for signal transmission and a conversion piece 3 with conductive performance. The conversion piece 3 comprises a first end 30 and a second end 31, the first end 30 is pivoted with the first pin J1, the second end 31 is connected with the movable seat 2 through a linkage structure, the second end 31 is further provided with an electrode contact 32, when the movable seat 2 moves along the first direction F1, the second end 31 of the conversion piece 3 can be driven to rotate relative to the first end 30 in the plane of the first direction F1 through the linkage structure, so that the electrode contact 32 on the second end 31 is abutted with one of the third pin J3 and the second pin J2.
In this embodiment, in a natural state, the electrode contact 32 abuts against the third pin J3, so that the first pin J1 is connected to the third pin J3, and the switch is in the first state.
When the switch needs to be switched to the second state, the movable seat 2 approaches the supporting base 1 along the first direction F1, and along with the movement of the movable seat 2, the linkage structure drives the second end 31 of the conversion member 3 to rotate, i.e. move downwards, relative to the first end 30 in the plane of the first direction F1, so that the electrode contact 32 on the second end 31 of the conversion member 3 contacts with the second pin J2, and the first pin J1 is connected with the second pin J2, thereby completing the switching operation of the circuit.
When the electrode contact 32 is switched from the third pin J3 to the second pin J2 or from the second pin J2 to the third pin J3, the electrode contact 32 is in static contact with the third pin J3 or the second pin J2, and sliding dynamic contact is not generated, so that electric sparks and friction generated in the switching process are effectively avoided. Through the optimization of the mechanical movement, the action of the switch is smoother, quicker and more reliable, and the switch is particularly suitable for an electronic system which needs high-speed response and high reliability.
On the other hand, referring to fig. 1 to 3 again, the linkage structure includes a supporting plate 4 and a tension spring 5, the supporting plate 4 includes a third end 40 and a fourth end 41, the third end 40 is connected with the movable base 2, the fourth end 41 is pivotally connected with the supporting base 1, and the third end 40 is tilted upward relative to the fourth end 41, that is, a distance between the third end 40 and the supporting base 1 is greater than a distance between the third end 41 and the supporting base 1. One end of the tension spring 5 is hooked and connected with the second end 31 of the conversion piece 3, the other end of the tension spring 5 is hooked and connected with the third end 40 of the support plate 4, and the abutting point of the electrode contact and the second pin is higher than the connecting point of the fourth end of the support plate and the support base.
In the present embodiment, when pressure is applied to the movable seat 2 to move the movable seat 2 close to the support base 1, the movable seat 2 applies pressure to the third end 40 of the support plate 4, so that the third end 40 of the support plate 4 rotates downward relative to the fourth end 41, and when the third end 40 rotates below the pivot point between the conversion element 3 and the first pin J1, the tension force exerted by the tension spring 5 on the second end 31 of the conversion element 3 changes from pulling obliquely upward to pulling obliquely downward, thereby pulling the second end 31 of the conversion element 3 to a position abutting against the second pin J2.
At this time, since the contact point of the electrode contact 32 with the second pin J2 is higher than the connection point of the fourth end 41 of the support plate 4 with the support base 1, the tension force exerted on the third end 40 of the support plate 4 by the tension spring 5 still provides the support plate 4 with a moment rotating upward relative to the fourth end 41, so that when the pressure on the movable base 2 disappears, the moment drives the support plate 4 to reset, so that the electrode contact 32 is reset to the position of abutting against the third pin J3.
On the other hand, the first pin J1 includes a first segment J10 and a second segment J11, the second pin J2 includes a third segment J20 and a fourth segment J21, the third pin J3 includes a fifth segment J30 and a sixth segment J31, the first segment J10, the third segment J20, and the fifth segment J30 are located outside the support base 1, the second segment J11, the fourth segment J21, and the sixth segment J31 are located inside the support base 1, and when the second end 31 of the conversion element 3 rotates, the electrode contact 32 selectively abuts against one of the fourth segment J21 and the sixth segment J31. In the present embodiment, for the first, second, and third pins J1, J2, and J3, switching of the connection state between each other is completed through the second, fourth, and sixth sections J11, J21, and J31 located on the inner side, and the switch is connected to the target circuit through the first, third, and fifth sections J10, J20, and J30 located on the outer side.
Further, the conversion member 3 is located above the support plate 4, and an avoidance groove 42 is provided on the support plate 4, and the electrode contact 32 abuts against the fourth section J21 of the second pin J2 through the avoidance groove 42. In this embodiment, through the arrangement of the avoidance groove 42 on the support plate 4, the cooperation between the support plate and the conversion member 3 is more compact, and the installation space is saved.
On the other hand, the electrode contact 32 is cylindrical, the electrode contact 32 is embedded in the conversion member 3, and the electrode contact 32 protrudes from the upper surface and the lower surface of the conversion member 3, so that the electrode contact 32 can be respectively abutted against the second pin J2 and the third pin J3.
On the other hand, at least two pairs of first pins J1, second pins J2, third pins J3 and two pairs of linkage structures are arranged on the support base 1 in parallel, and when the movable base 2 moves, the connection states among the two pairs of first pins J1, second pins J2 and third pins J3 are controlled through the at least two pairs of linkage structures, so that the micro-motion mechanical switch can control the states of two circuits simultaneously.
On the other hand, a trigger guide rod 6 is also arranged on the movable seat so as to facilitate the operation of the movable seat 2.
In another aspect, as shown in fig. 4, the micro-mechanical switch in this embodiment further includes a housing 7, where the housing 7 encapsulates the movable base 2 and the supporting base 1.
