Abstract
The utility model relates to an automatic adjustment mechanism of a micro switch dome. The automatic adjustment mechanism comprises a dome and a plurality of silver contacts connected on the dome, wherein the dome comprises a movable dome and an auxiliary dome, the middle part of the auxiliary dome is folded downwards and connected with the movable dome; the silver contacts comprise upper silver contacts and lower silver contacts which are mutually pivoted female and male rivets, the movable dome is provided with first through holes of the same number with the silver contacts, the lower silver contacts pass through the corresponding first through holes on the movable dome and cooperate with the upper silver contacts and rivet on the auxiliary dome. The automatic adjustment mechanism has the automatic adjustment function, and effectively solves the problem of the prior art that the silver contacts cannot contact with fixed contacts due to different connection heights of the silver contacts on the dome.
Description
Technical field
The utility model relates to the sensitive switch technical field, specifically refers to a kind of automatic governor motion of sensitive switch shell fragment.
Background technology
Sensitive switch the frequent changing-over circuit of need, control automatically in the equipment and safeguard protection etc.; be widely used in electronic equipment, instrument and meter, mine, electric power system, household electrical appliance, electric equipment; and military field such as space flight, aviation, naval vessel, guided missile, tank; though switch is little, play irreplaceable effect.At present, the inner employed shell fragment of sensitive switch generally all is that silver contact directly is riveted on the shell fragment, so silver point does not possess automatic regulatory function.So; when silver contact outnumber one the time; because the height that each silver contact is connected on the shell fragment is inconsistent, cause the position to touch fixed contact earlier near the silver contact of fixed contact through regular meeting, and other silver contact can't contact the phenomenon of big fixed contact.Therefore, to solve be research purpose of the present utility model to the problem that exists at above-mentioned prior art.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model is to provide a kind of automatic governor motion of sensitive switch shell fragment, can effectively solve the problem that above-mentioned prior art exists.
The technical solution of the utility model is: a kind of automatic governor motion of sensitive switch shell fragment, comprise shell fragment and be connected in some silver contacts on the shell fragment, described shell fragment comprises movable contact spring and auxiliary shell fragment, and folding is connected in described movable contact spring under the described auxiliary shell fragment mid portion; Described silver contact comprises top silver contact and lower part silver contact, described top silver contact and lower part silver contact are arranged to the primary and secondary rivet of riveted joint mutually, described movable contact spring is provided with and the same number of first through hole of described silver contact, and described lower part silver contact passes on the movable contact spring corresponding first through hole and cooperates with the top silver contact and be riveted on the auxiliary shell fragment.
Described auxiliary shell fragment is provided with corresponding second through hole in the corresponding position of first through hole with movable contact spring, and described top silver contact passes on the auxiliary shell fragment corresponding second through hole and cooperates with the lower part silver contact to be riveted on and assist on the shell fragment.
Described top silver contact is arranged to sub-rivet, and described lower part silver contact is arranged to female rivet of matching with the top silver contact, and the diameter of described first through hole is greater than the nail shank diameter of the lower part silver contact head diameter less than the lower part silver contact; The diameter of described second through hole is greater than the nail shank diameter of the top silver contact head diameter less than the top silver contact, and the diameter of described second through hole is less than the nail shank diameter of lower part silver contact.
Advantage of the present utility model: the utility model is by when shell fragment moves toward fixed contact, it is close toward fixed contact with the silver contact that is riveted on the auxiliary shell fragment that movable contact spring drives auxiliary shell fragment, until silver contact contact fixed contact, when the silver contact height is inconsistent, behind the silver contact elder generation contact fixed contact near fixed contact, movable contact spring forms extruding force or pulling force to auxiliary shell fragment, makes the certain deformation of auxiliary shell fragment generation, automatically regulate the height of silver contact, make its contact fixed contact.

Embodiment
Now embodiment is described in further detail structure of the present invention by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to figure 1, Fig. 2, a kind of automatic governor motion of sensitive switch shell fragment comprises shell fragment 1 and is connected in some silver contacts 2 on the shell fragment 1, and silver contact of the present utility model is two.Described shell fragment 1 comprises movable contact spring 1-1 and auxiliary shell fragment 1-2, and folding is connected in described movable contact spring 1-1 under the described auxiliary shell fragment 1-2 mid portion 1-21; Described silver contact 2 comprises top silver contact 2-1 and lower part silver contact 2-2, described top silver contact 2-1 and lower part silver contact 2-2 are arranged to the primary and secondary rivet of riveted joint mutually, described movable contact spring 1-1 is provided with and described silver contact 2 the same number of first through hole 1-11, and described lower part silver contact 2-2 passes movable contact spring 1-1 and goes up the corresponding first through hole 1-11 and cooperate with top silver contact 2-1 to be riveted on and assist shell fragment 1-2.
Described auxiliary shell fragment 1-2 is provided with the corresponding second through hole 1-22 in the corresponding position of the first through hole 1-11 with movable contact spring 1-1, and described top silver contact 2-1 passes auxilliary group shell fragment 1-2 and goes up the corresponding second through hole 1-22 and cooperate with lower part silver contact 2-2 to be riveted on and assist on the shell fragment.
Described top silver contact 2-1 is arranged to sub-rivet, described lower part silver contact 2-2 is arranged to female rivet of matching with top silver contact 2-1, and the diameter of the described first through hole 1-11 is greater than the nail shank diameter of the lower part silver contact 2-2 head diameter less than lower part silver contact 2-2; The diameter of the described second through hole 1-22 is greater than the nail shank diameter of the top silver contact 2-1 head diameter less than top silver contact 2-1, and the diameter of the described second through hole 1-22 is less than the nail shank diameter of lower part silver contact 2-2.
The course of work of the present utility model:
When shell fragment 1 drives silver contact 2 upwards near upper fixed contact 3, movable contact spring 1-1 drives auxiliary shell fragment 1-2 and is riveted on the silver contact 2 of assisting on the shell fragment 1-2 and up moves, until silver contact 2 contact upper fixed contacts 3, when the height of silver contact 2 is inconsistent, highly higher by silver contact earlier behind the contact upper fixed contact 3, movable contact spring 1-1 forms extruding force to auxiliary shell fragment 1-2, make auxiliary shell fragment 1-2 that certain deformation take place, automatically regulate the height of highly lower silver contact, make its contact upper fixed contact 3.
