Abstract
The invention discloses a no-overhanging pin patch type silica gel elastic button comprising a pedestal and a button soft body. The button soft body comprises a button convex body, an elastic soft body and a conductive contact. The elastic soft body is a tapered cylinder shape. The small mouth internal edge of the elastic soft body is connected with the button convex body. The large mouth end of the elastic soft body is connected with the upper surface of the pedestal. The conductive contact is arranged at the lower end surface of the button convex body. The no-overhanging pin patch type silica gel elastic button is characterized in that the pedestal is internally provided with internal pins which do not exceed the external side of the pedestal. The lower end surfaces and the external side surfaces of the internal pins are welding surfaces. The internal pins are arranged on pin supports. Pin connecting frames connected with the internal pins are arranged between the internal pins. The internal pins and the pin connecting frames are included in the pin supports. The secondary bending process of pin welding is avoided by the button, and pin coplanarity is great so that the requirements for pin size, shape and number of different buttons can be simply realized. The button is suitable for application of surface mounting and also has advantages of high-density arrangement, low manufacturing cost and great practicality.

First, due to existing conductive elements function button criteria of right and wrong part, each electronic product all needs to open a corresponding secondary silica gel push-button mould; For the product had compared with multifunction push key, can output unitary mould and realize integral type silica gel push-button, be equally also the problem of keeping away the secondary overall silica gel push-button mould coordinated of a unavoidable electronic product corresponding; The button of difference in functionality, particularly shape, size are had to the situation of bigger difference, need the input of carrying out the manpower and materials such as Design of Dies, manufacture, cause the wasting of resources of a large amount of overlapping investment.Secondly, the assembling process of existing silica gel push-button mainly relies on manually, and production efficiency is low; Silica gel push-button is general all with angle and relevant Position Design, in practical set process, utilize and shift to an earlier date the corresponding location hole offered in the circuit board, manually position and assemble, namely by the location hole manually angle of each conductive elements function button being passed wiring board.Rely on and manually position and assemble, cause production inefficiency, high expensive, and need larger Work places.
Based on the background of non-standard component, although various measure of raising the efficiency can be taked, as used the ameliorative way such as automation equipment, auxiliary encapsulation, the problem that input cost is high and production efficiency is low all fundamentally can not be solved.Use the design philosophy of electronic devices and components, surface mounting technology is used for structural design, the production of silica gel push-button and applies and will bring revolutionary change to industry.Use for reference surface mounting technology and the rule of development thereof of electronic devices and components, realize SMD silica gel push-button structure and improve toward high density, low manufacturing cost direction, there is very strong novelty and necessity.
Summary of the invention
Order of the present invention is for the deficiencies in the prior art, and provide a kind of without the SMD silicone elastomer button of overhanging pin, this button is applicable to surface mounting technology, has again high density, the feature that cheap for manufacturing cost, practicality is good.
The technical scheme realizing the object of the invention is:
A kind of without the SMD silicone elastomer button of overhanging pin, comprise base and button software, described button software comprises key convex body, elastic soft and conductive contact, the tapered cylindrical shape of elastic soft, the osculum inner edge of elastic soft is connected with key convex body, and the big opening end of elastic soft is connected with base upper surface, and conductive contact is arranged on the lower surface of key convex body, unlike the prior art
Be provided with the interior pin not exceeding chassis outer side in described base, the lower surface of described interior pin and lateral surface are solder side.
Described interior pin is arranged on pin support, is provided with the pin link be attached thereto between interior pin, and interior pin, pin link are included in pin support.
Described pin support and base are connected as a single entity.
Described pin link is encapsulated in inside base.
Between interior pin, be open circuit by design pin link, electrical open between pin in realizing.
The lower surface of described base is provided with symmetrical base convex body, and when using paster button, base convex body plays the stressed effect of balance button.
Described interior pin is at least 2, and interior pin total quantity is the multiple of 2, and distributes at button bottom symmetrical.
Described pin support is array type pin support.
This SMD silicone elastomer button, the secondary avoiding welding pin bends technique, and lead coplanarity is good, can the requirement of simple realization different key pin size, shape and quantity; This button is not only applicable to surface mount application, and having again can high-density array, the advantage that cheap for manufacturing cost, practicality is good.
