Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Depend on figure 1 , figure 2 Given, the present invention includes a closed cavity, mercury and an insulating framework, the insulating framework 6 has a closed cavity 2, and the framework 6 has a first electrode 1 and a second electrode 5 extending out of the framework 6 and insulated from each other, The contacts of the first electrode 1 and the second electrode 5 communicate with the cavity 2, the cavity 2 is filled with mercury 4, and a layer of insulating powder 3 is adsorbed on the inner surface of the cavity 2 and the mercury 4.

[0010] In order to ensure the use effect, the volume of the cavity 2 is 15%-60% larger than that of the mercury 4 .

[0011] The insulating powder 3 is a non-conductive particle of ≤0.2mm, or a mixed non-conductive particle, such as one of plastic insulating particles, titaniu...

Abstract

The invention relates to a powder-type insulated high-speed minisize impact switch. A current glass mercury switch has a large volume. There is a blind spot during working. Consistency and repeatability are not stable. By using the impact switch of the invention, the above problems can be effectively solved. The impact switch comprises: a sealed cavity, mercury and an insulation skeleton. The insulation skeleton is provided with the sealed cavity. A first electrode and a second electrode, which are mutually insulated with each other, are arranged in the skeleton and extend out of the skeleton. Contacts of the first electrode and the second electrode are communicated with the cavity. The cavity is filled with the mercury. A layer of an insulation powder is adsorbed on an inner surface of the cavity and the mercury. In the invention, a structure is compact. The switch is small and unique. Usage is convenient. Working is reliable and stable. The impact switch belongs to the innovation of a microelectronic switch.

Description

technical field [0001] The invention relates to an electric switch, in particular to a powder-type insulated high-speed miniature collision switch. Background technique [0002] Existing glass mercury switch, its disconnection mode is to take air as insulating medium, and when promptly moving and static contact disconnection, be to rely on air insulation to block electric current. Due to the longer travel of the air-insulated contacts, this mercury switch is relatively bulky. In addition, because this type of inertial switch always has directionality, especially when the static contact is at the bottom and the mercury is at the top, it cannot be used and worked normally (with blind spots), and the air-insulated travel is long, the response is slow, and the high-speed It is not available for occasions, and because mercury has a smooth surface, it is easy to form a vacuum suction cup effect when in contact with the smooth glass inner wall, resulting in insensitive response, u...
