Abstract
The invention discloses a novel onboard switch composed of a plug pin base and a flexible plug pin. The plug pin base is composed of a substrate, a lower metal elastic sheet and an upper metal elastic sheet. The substrate is made of insulated materials. The lower metal elastic sheet is of a rectangular thin sheet shape and is installed on the left side of the substrate. The upper metal elastic sheet is of an n shape. The right side of the upper metal elastic sheet is installed on the right side of the substrate. When no external force is exerted, the left side of the upper metal elastic sheet makes natural contact with the lower metal elastic sheet, so that a plug pin hole is formed between the upper metal elastic sheet and the lower metal elastic sheet. The flexible plug pin is composed of a front plastic portion and a rear metal portion. The tail portion of the plastic portion is fixedly connected with the head portion of the metal portion in a seamless mode. When the left side of the upper metal elastic sheet makes contact with the lower metal elastic sheet, the head portion of the plastic portion can extend into the plug pin hole between the upper metal elastic sheet and the lower metal elastic sheet. The novel onboard switch has the advantages of being large in borne current, applicable to occasions with the strict requirement for the size and the weight, and capable of serving as not only a circuit power supply switch but also a motion detection switch.
Description
Technical field
The present invention relates to a kind of new type of plate load switch that the circuit supply switch also can be used as action detection switch that both can be used as.
Background technology
At present domestic have the volume of switch of reliability index and index of aging all larger, no matter be sensitive switch, push-button switch, or toggle switch, minimum also have 13 * 5.1 * 11.2mm, if will be with this type of switch as circuit supply switch or action detection switch, design and installation structure for this reason, volume is larger, and the electric current that the switch of this kind of small size can bear is also limited, and maximum is no more than 5A.In the normal domestic switch, the printed circuit board (PCB) of volume minimum is installed the class sensitive switch both at home and abroad, generally can only be as artificial shake-up sense switch, and the electric current born is little, and can not press for a long time.
Summary of the invention
The technical problem to be solved in the present invention is, for existing switch above shortcomings, provides a kind of new type of plate load switch, reduces the volume of switch, saves mounting structure, simultaneously in order to improve the ability of switch loaded current.
The present invention solves the problems of the technologies described above adopted technical scheme to be:
A kind of new type of plate load switch, consist of plug housing and soft latch, and described plug housing is comprised of substrate, lower metal clips, upper metal clips, and described substrate adopts insulating material to make; Described lower metal clips is rectangle laminar, is arranged on the left side of substrate; Described upper metal clips is Ω shape, the right side of upper metal clips is arranged on the right side of substrate, and during without external force, the left side of upper metal clips contacts naturally with lower metal clips, with after lower metal clips contacts, form a pin hole when the left side of upper metal clips between upper metal clips and lower metal clips; Described soft latch partly is comprised of the parts of plastics of front end and the metal of rear end, and the head of the afterbody of parts of plastics and metal part is seamless affixed; The head size of described parts of plastics meets: when the left side of upper metal clips with after lower metal clips contacts, the head of parts of plastics can stretch in the pin hole formed between metal clips and lower metal clips, and the head size of parts of plastics is enough to the pin hole of upper metal clips and the formation of lower metal clips is strutted.
Press such scheme, the head of the parts of plastics of described soft latch is back taper tip shape, and the afterbody of parts of plastics is cylindricality; The metal part of soft latch is coiled into cylindricality by steel wire, and the head of metal part and the afterbody equal diameter of parts of plastics.
Press such scheme, the afterbody of described metal part is provided with a relieving ring, and described relieving ring passes through the afterbody embowment of cylindricality steel wire and forms with the cylindricality fixation with steel wire, and process through scalding tin on the surface of relieving ring.
Press such scheme, between described upper metal clips, lower metal clips and substrate, adopt soldering affixed, the two ends, left and right of described substrate are respectively equipped with that copper pad is covered on a left side, copper pad is covered on the right side, and lower metal clips soldering is covered on copper pad on a left side, and upper metal clips soldering is covered on copper pad on the right side.
Press such scheme, the contact-making surface formed after described upper metal clips contacts with lower metal clips is square; The material of described upper metal clips, lower metal clips is that copper is gold-plated, or copper alloy is gold-plated, or silver alloy, or silver alloy is gold-plated, or take the composite silver alloy that copper alloy makes as basis material.
Press such scheme, described substrate is the rigidity copper-clad plate, and its material is epoxy resin, or is mylar, or is metal species, or is ceramic-like.
Press such scheme, the bottom of described substrate is provided with metal pad.
Press such scheme, but the large tracts of land layer is all left in the edge of described substrate and bottom.
Press such scheme, the surrounding of described plug housing is provided with the protective cover of a plastic injection-moulded one-tenth, and (protective cover is the cuboid cavity-like, stick on the surrounding of substrate), the both sides of the corresponding soft latch of this protective cover insert division all have a circular hole, the circular hole of every side extends and forms one section hollow ring in protective cover, the Ω shape edge laminating of the edge of hollow ring and upper metal clips, both can prevent that soft latch from extracting rear foreign material and entering in protective cover from pin hole, in case affect the next time of plate load switch, use, can guarantee again when soft latch inserts the pin hole formed between upper metal clips and lower metal clips, the head of the parts of plastics of soft latch and upper metal clips are better fitted.
Operation principle of the present invention: the conducting that whether contacts the control board load switch of upper metal clips and lower metal clips and closing, during pin hole in parts of plastics (insulating end) insertion of soft latch between metal clips and lower metal clips, upper metal clips is softened and can not contact with lower metal clips, thereby the control board load switch is closed; After extracting soft latch, upper metal clips contacts naturally with lower metal clips, the conducting of control board load switch.
The present invention has following beneficial effect:
1, adopt two shell fragment designs, between upper metal clips and lower metal clips, contact-making surface is large, but guarantees that loaded current is large;
Do not need to design any supplementary structure when 2, this plate load switch is worked, only need in conjunction with special soft latch, as long as direction of action is contrary with soft latch direction of insertion, or guarantee in a hemisphere face, all can operate successfully with it, be applicable to relative displacement to equipment or device power supply and detect the occasion of relative displacement This move, the alternative existing all kinds of switches that apply to this field, volume is little, lightweight, be specially adapted to volume and weight is had the occasion of strict demand;
3, this plate load switch both can be used as the circuit supply switch, also can be used as action detection switch; Both can directly be welded on circuit board, also can be arranged on device interior with screw.
