Abstract

The utility model discloses a micro procedure switch, which is composed of a shell unit, a conductive terminal unit and a plurality of poking elements. The shell unit is composed of an isolation assembled base and a sealing cover; the base has a plurality of isolated fixing grooves. The terminal unit is composed of a plurality of fixing terminals and mobile terminals which are fixed and inserted in the fixing groove. Each poking element and an inner terminal are connected with the sealing cover; an outer terminal is positioned on the outer of the shell unit. When the poking element is positioned at a break over place, the poking element pushes the mobile terminal to electrically connect with the fixing terminal; when the poking element is positioned at a non break over place, the poking element releases the mobile terminal separating to the fixing terminal. The fixing and mobile terminal is respectively inserted into the structure of the fixing groove without embedding, ejaculating and producing the base, therefore, the difficulty and cost of producing the micro procedure switch is reduced.

Description

Miniature program switch

Technical field

The utility model relates to a kind of miniature program switch, particularly relates to a kind of miniature program switch that reduces manufacture difficulty and cost.

Background technology

Fig. 1 shows a kind of in the past miniature program switch 1, and this miniature program switch 1 is the terminal unit 11 that comprises a conduction, a hollow housing unit 12, and most shifting parts 13.

This terminal unit 11 comprises the spaced the first terminal of most roots 111, and most roots are spaced and with these the first terminal 111 corresponding second terminals 112, and can be relative to this first and second terminal 111,112 at a conduction position and the moving member 113 that move non-conduction position.The pitch of this miniature program switch 1 (pitch) is to belong to 1.27 millimeters specifications, and the distance that distance that just per two adjacent the first terminals are 111 and per two adjacent second terminals are 112 is neither greater than 1.27 millimeters.Described first and second terminal 111,112 has 114,115, buried sections 116,117 of an inner segment that can be electrically connected with this moving member 113, and a revealed section 118,119.

This housing unit 12 comprises a pedestal 121 and capping 122 of insulation and assembling mutually, this pedestal 121 is imbedded injection molding with described buried section 116,117, this capping 122 has the loose slot 123 of most described relatively the first terminals 111, and described loose slot 123 extends to a lateral surface from 122 1 medial surfaces of this capping.Described moving member 113 all is positioned at this housing unit 12 with described inner segment 114,115, and described revealed section 118,119 is positioned at outside this housing unit 12, this pedestal 121 and capping 122 gummeds is packaged together again.

Described shifting part 13 places described loose slot 123 respectively, and 13 1 the inners of each shifting part are articulated in 122, one outer ends of this capping and are positioned at outside this housing unit 12.

Consult Fig. 1 and Fig. 2, this shifting part 13 can move between a conduction position and a non-conduction position relative to this housing unit 12, when this shifting part 13 is positioned at this conduction position, these shifting part 13 these moving members 113 of pushing and pressing, this moving member 113 is positioned on the inner segment 114,115 of this corresponding first and second terminal 111,112 simultaneously, to be electrically connected this first and second terminal 111,112.When this shifting part 13 was positioned at this non-conduction position, these shifting part 13 these moving members 113 of pushing and pressing made this moving member 113 break away from the inner segment 115 of this second terminal 112, make this first and second terminal 111,112 outages.

Though this miniature program switch 1 can this first and second terminal 111,112 of conducting, or make this first and second terminal 111,112 outages, still have following disappearance:

One, this first and second terminal the 111, the 112nd is imbedded and is penetrated in this pedestal 121, under the specification of volume miniaturization (pitch1.27mm), has quite high manufacture difficulty, and the not high awkward situation of product yield is arranged, when having high worker relatively and the disappearance of cost.

Two and practice on need to place in addition a moving member 113, the assembling complexity that will improve miniature in the past program switch 1 is wholely formed member with increasing, and have manufacture difficulty higher with the shortcoming that raises the cost.

The utility model content

The purpose of this utility model is that a kind of miniature program switch that can reduce manufacture difficulty and cost is being provided.

The miniature program switch of the utility model comprises the terminal unit of a hollow housing unit, a conduction, and most shifting parts, it is characterized in that:

This housing unit comprises a pedestal and capping of insulation and mutual assembling, and this pedestal has most spaces and arrangement is formed at the holddown groove that medial surface of this pedestal extends towards a lateral surface.This capping has the loose slot of most described relatively holddown grooves, and described loose slot extends to a lateral surface from medial surface of this capping.

This terminal unit comprises most root fixed terminals, and most root movable terminal.Each root fixed terminal has first canned paragraph that inserts and be fixed in this corresponding holddown groove one end section, and one from outer end of this first canned paragraph towards this housing unit first linkage section extending out.Each root movable terminal have second canned paragraph that inserts this holddown groove, one from outer end of this second canned paragraph towards this housing unit second linkage section extending out, and an active segment that is arranged at this inner of second canned paragraph, this second canned paragraph is to be fixed on the end section of opposite this first canned paragraph of this corresponding holddown groove.

Described shifting part places described loose slot respectively, and the inner of each shifting part is articulated in this capping, and an outer end is positioned at outside this housing unit.This shifting part can move between a conduction position and a non-conduction position relative to this housing unit, and when being positioned at this conduction position, this shifting part pushes against this active segment to be electrically connected this first canned paragraph.When being positioned at this non-conduction position, this shifting part discharges this active segment to be made and breaks away from this first canned paragraph.

The beneficial effect of the miniature program switch of the utility model is that described first and second canned paragraph inserts the structure of described holddown groove respectively, this pedestal need just can not made through the mode of imbedding ejaculation, thereby reduce manufacture difficulty and cost.
