Abstract
The utility model discloses a netted contact micro -gap switch, including the shell body, its characterized in that: the shell body is inside to have a cavity, and the institute cavity of saying bottom is equipped with the sub - support in left and right both ends, installs the sharing terminal on the sub - support of institute's left end of saying, installs on the sub - support of institute's right -hand member of saying and normally opens the terminal, and the normal close terminal is installed to one side of the sub - support of right -hand member of saying, and the normal close terminal of saying has a horizontal limit and a vertical limit, the lower surface and the upper surface of normally opening the terminal on the horizontal limit of normal close terminal are equipped with netted stationary contact respectively, the up end of sharing terminal is equipped with the extension spring support. The utility model discloses stability and security, sensitivity, contact are stably.
Description
Technical field
The utility model relates to a kind of electrical instrumentation parts, specifically a kind of netted contact sensitive switch.
Background technology
Due in the prior art, it is plane that described dynamic and static contact is round platform, and sensitive switch in the energized state easily produce spark cause contact oxidation produce oxide, when there is small foreign matter in the contact point of dynamic and static contact round table surface, greatly reduce sensitivity and the contact stabilization of switch, or cause switch failure, even may cause security incident in the energized state.
Utility model content
The utility model object there is provided a kind of stability and the fail safe that improve switch, the netted contact sensitive switch of sensitivity, contact stabilization.
The utility model technical solution problem provides following scheme:
A kind of netted contact sensitive switch, comprise shell body, it is characterized in that: described shell body inside has a cavity, said cavity bottom is provided with a left side, right two-terminal support, said left terminal support is provided with common terminal, said right terminal support is provided with Chang Kaiduan, and the upper surface of Chang Kaiduan is provided with, the side of said right terminal support is provided with normally closed terminal, said normally closed terminal has a horizontal sides and vertical edge, the lower surface of the horizontal sides of described normally closed terminal and the upper surface of Chang Kaiduan are respectively equipped with netted fixed contact, the upper surface of described common terminal is provided with extension spring support, described extension spring support is provided with extension spring, the right-hand member of described extension spring is installed with movable contact spring, on described movable contact spring one end, lower surface is provided with moving contact, the face that described fixed contact contacts with moving contact is network structure, shell body above the interlude of described extension spring is provided with button hole, in described button hole, button is installed, the lower end of described button is pressed in the interlude of extension spring, the upper end of described button contacts with pressure handle.
The left end of described pressure handle is fixedly mounted on the sidewall of shell body, and right-hand member is free to rotate.
The utility model wherein movable contact spring is provided with moving contact, and Chang Kaiduan and normally closed terminal two ends are respectively equipped with netted fixed contact, netted fixed contact, and in moving contact both sides in symmetrical up and down.The moving contact of described movable contact spring one end is communicated with netted fixed contact on normally closed terminal, the other end is fixed on common terminal support by extension spring and forms touch device, lower press handle, button is communicated with by realizing moving contact instantaneous changing-over between netted fixed contact and netted fixed contact with the interaction of extension spring.In order to improve sensitivity and the contact stabilization of switch, the face that fixed contact contacts with moving contact is designed to network structure, also fully can contact conducting when making each contact there is small foreign matter, the contact point normal conversion not affecting switch is communicated with, thus improves stability and the fail safe of switch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model entirety.
Fig. 2 is the structural representation of Chang Kaiduan in the utility model.
Fig. 3 is the structural representation of normally closed terminal in the utility model.
