Abstract
The utility model discloses a canned type key switch, a serial communication port, press the button, go up capsule, side seal limit, contact, insulating main part and spring button structure including the column, the position in the positive centre of insulating main part is installed for the cylinder form to the column button, insulating main part is inside to have a cavity that can hold spring button structure, and spring button structrual installation is in this cavity, and the column button is located the spring press -button structure directly over and rather than direct contact, the upper portion border position that insulating main part has two opposite flanks all has an interior concave groove holes, all has one to be similar to " nearly " type channel on two opposite flanks in addition, go up laminating piece of interior concave groove holes contact department downwardly extending of capsule and insulating main part, including the laminating piece is installed in the concave groove holes. The utility model discloses a go up the structural design of capsule, side seal limit and insulating main part for this switch structure leakproofness is better, long service life, and the good reliability, the security is high, is suitable for popularization and application.
Description
Technical field
The utility model relates to electronic devices and components manufacturing technology field, specifically a kind of closed type key switch.
Background technology
Key switch is a kind of simple in structure, application master control electrical apparatus very widely. At electric automatic control electricityLu Zhong, for manually sending control signal with control contactor, relay, electromagnetic starter etc. ExistingAlthough key switch can meet market demand to a certain extent, the key switch wiring of prior art is steadyQualitative poor, and be easier to occur maloperation, affect the normal use of key switch, its applicability is existedBe restricted to a certain extent.
Utility model content
For solving the deficiencies in the prior art, the utility model proposes a kind of closed type key switch.
The utility model adopts following technical scheme: a kind of closed type key switch, it is characterized in that, and compriseColumn button, upper capsule, side sealing, contact, insulating body and spring press-key structure, described column buttonFor cylindrical shape, be arranged on the position of the middle of insulating body; Described insulating body inside has can hold bulletThe cavity of spring press-key structure, spring press-key structure is arranged in this cavity, and column button is positioned at spring buttonDirectly over structure and be in direct contact with it; Described insulating body has the top edge position of two opposite flanksAll there is an indent notch, on another two opposite flanks, all have approximate " several " type conduit; Upper capsuleTo adhesive piece of downward-extension, adhesive piece is arranged on indent notch with the indent notch contact position of insulating bodyIn; Side sealing is similar to " several " type, with shape, the size phase of " several " type conduit on insulating body sideCoupling, side sealing is two, is arranged on respectively in " several " type conduit on insulating body side; Described touchingSheet is two, and being arranged on respectively two of insulating body has the lower edge position of the side of indent notch, itsThe outside of Gai side, one end, the other end is arranged in the cavity of insulating body inside.
The end of spring press-key structure includes a metallic conduction sheet, and in the time pressing column button, spring is pressedBond structure is all electrically connected metallic conduction sheet with two contacts, switch is in conducting state; When again pressingWhen column button, spring press-key structure disconnects metallic conduction sheet and two contacts, and switch is in cutting outState.
Described contact is that conductive material is prepared from.
Beneficial effect: the utility model, by the structural design of upper capsule, side sealing and insulating body, makesThis construction of switch better tightness, long service life, good reliability, safe, be suitable for and apply.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail. Following content is in conjunction with concretePreferred embodiment the utility model is described in further details, can not assert of the present utility model concreteEnforcement is confined to these explanations. For the utility model those skilled in the art, do not departing fromUnder the prerequisite of the utility model design, its framework form can be flexible and changeable, can derive series of products.The following some simple deduction or replace of doing, all should be considered as belonging to the right that the utility model submits to and wantAsk the definite scope of patent protection of book.
A kind of closed type key switch of the utility model (referring to Fig. 1-4), is characterized in that, comprises columnButton 1, upper capsule 2, side sealing 3, contact 4, insulating body 5 and spring press-key structure, described columnButton 1 is cylindrical shape, is arranged on the position of the middle of insulating body 5; Described insulating body 5 insideHave the cavity that can hold spring press-key structure, spring press-key structure is arranged in this cavity, and column button 1Be positioned at spring button structure directly over and be in direct contact with it; Described insulating body 5 has two opposite flanksTop edge position all have an indent notch, on another two opposite flanks, all have one approximate " several "Type conduit. Upper capsule 2, is fitted to adhesive piece of downward-extension with the indent notch contact position of insulating body 5Sheet is arranged in indent notch; Side sealing is similar to " several " type, with " several " type on insulating body 5 sidesShape, the size of conduit match, and side sealing 3 is two, are arranged on respectively on insulating body 5 sidesIn " several " type conduit. Described contact 4 is two, and two that are arranged on respectively insulating body 5 have inner groovyThe lower edge position of the side of mouth, the outside of Gai side, its one end, the other end is positioned at insulating body 5In the cavity of portion.
The end of spring press-key structure includes a metallic conduction sheet, in the time pressing column button 1, and springPress-key structure is all electrically connected metallic conduction sheet with two contacts 4, switch is in conducting state; When againWhile pressing column button 1, spring press-key structure disconnects metallic conduction sheet and two contacts 4, switchIn closed condition.
Described contact 4 is prepared from for conductive material. Spring control section and the city of described spring press-key structureThe structure of the common spring control section for the snap switch inside on circuit of face is similar.
The utility model, by the structural design of upper capsule, side sealing and insulating body, makes this construction of switchBetter tightness, long service life, good reliability, safe, be suitable for and apply.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also be rightAbove-mentioned embodiment changes and revises. Therefore, the utility model is not limited to and discloses above and describeDetailed description of the invention, also should fall into power of the present utility model to modifications and changes more of the present utility modelIn the protection domain that profit requires. In addition, although used some specific terms in this description, theseTerm just for convenience of description, does not form any restriction to the utility model.
