Abstract
The utility model relates to a microswitch, including casing, push rod, last static contact, lower static contact and movable contact spring, its characterized in that: but the casing on be equipped with the first recess that the ammunition feed spring holds, during the one end of this spring is fixed in first recess, the one end of push rod wear out the casing setting, the other end corresponds the setting with first recess to other end fixed connection with the spring, the casing on still seted up the second recess, the push rod on be equipped with horizontal portion, should horizontal portion and second recess sliding connection. The utility model discloses lie in: seted up the second recess on the casing, when promoting the push rod, horizontal portion on the push rod has reduced the area of contact with the casing, also reduced simultaneously with the coefficient of friction of casing, improved the flexibility ratio of push rod with the casing, guaranteed microswitch's operation sensitivity, make the microswitch can timely realization break -make function.
Description
Technical field
The utility model relates to field of switches, refers to a kind of sensitive switch especially.
Background technology
At present, on market some existing sensitive switch be present in operation insensitive, make sensitive switch can not realize on-off function timely; And sensitive switch uses parts inner long afterwards very easily to damage, and reduces useful life.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the sensitive switch of a kind of manual dexterity, inner parts not easily damaged and long service life.
The technical solution of the utility model is achieved in that a kind of sensitive switch, comprise housing, push rod, upper static contact, lower static contact and movable contact spring, it is characterized in that: described housing is provided with first groove that can hold for spring, one end of this spring is fixed in the first groove, one end of described push rod passes housing and arranges, the other end is corresponding with the first groove to be arranged, and be fixedly connected with the other end of spring, the middle-end of described push rod is provided with movable contact spring, this movable contact spring is provided with first protruding and the second projection, described upper static contact is provided with corresponding three projection protruding with first, described lower static contact is provided with corresponding four projection protruding with second, described housing also offers the second groove, described push rod is provided with transverse part, this transverse part and the second groove are slidably connected.
By adopting technique scheme, housing offers the second groove, when promoting push rod, transverse part on push rod reduces the contact area with housing, also reduce the coefficient of friction with housing simultaneously, improve the flexibility ratio of push rod and housing, ensure that the Operational Figure Of Merit of sensitive switch, make sensitive switch can realize on-off function timely, this structural design, low cost of manufacture, easy installation and removal, usability is strong, is easy to promote.
The utility model is set to further: the width of described transverse part and the width ratio of push rod are 1.5-1.
By adopting technique scheme, ensure that the bulk strength of push rod, extending useful life.
The utility model is set to further: the upper end of described housing comprises for push rod through the base portion arranged, and the both sides of this base portion are connected with oblique portion, and this oblique portion and base portion angulation are 120 degree.
By adopting technique scheme, add the intensity of housing upper end, in push rod and base portion sliding process, oblique portion has effectively disperseed push rod to act on thrust on base portion, ensure that the resistance to overturning of sensitive switch, be also provided with four blocks of magnet, a spark and electric arcing can be prevented.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model embodiment structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model discloses a kind of sensitive switch, comprise housing 1, push rod 2, upper static contact 3, lower static contact 4 and movable contact spring 5, in the utility model is specifically implemented, described housing 1 is provided with first groove 7 that can hold for spring 6, one end of this spring 6 is fixed in the first groove 7, one end of described push rod 2 passes housing 1 and arranges, the other end is corresponding with the first groove 7 to be arranged, and be fixedly connected with the other end of spring 6, the middle-end of described push rod 2 is provided with movable contact spring 5, this movable contact spring 5 is provided with the first protruding 51 and second projection 52, described upper static contact 3 is provided with three projection 31 corresponding with the first projection 51, described lower static contact 4 is provided with four projection 41 corresponding with the second projection 52, described housing 1 also offers the second groove 8, described push rod 1 is provided with transverse part 9, this transverse part 9 and the second groove 8 are slidably connected.
By adopting technique scheme, housing offers the second groove, when promoting push rod, transverse part on push rod reduces the contact area with housing, also reduce the coefficient of friction with housing simultaneously, improve the flexibility ratio of push rod and housing, ensure that the Operational Figure Of Merit of sensitive switch, make sensitive switch can realize on-off function timely, this structural design, low cost of manufacture, easy installation and removal, usability is strong, is easy to promote.
In the utility model is specifically implemented, the width of described transverse part 9 and the width ratio of push rod 2 are 1.5-1.
By adopting technique scheme, ensure that the bulk strength of push rod, extending useful life.
In the utility model is specifically implemented, the upper end of described housing 1 comprises for push rod 2 through the base portion 101 arranged, and the both sides of this base portion 101 are connected with oblique portion 102, and this oblique portion 102 is 120 degree with base portion 101 angulation.
By adopting technique scheme, add the intensity of housing upper end, in push rod and base portion sliding process, oblique portion has effectively disperseed push rod to act on thrust on base portion, ensure that the resistance to overturning of sensitive switch.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
