Abstract
The utility model provides a keypad with integrated spring sheet and contact and relates to the keypad used in an electronic product. The keypad comprises a keypad body, a glue layer, a polyester sheet, a metal spring sheet, a TPU (thermoplastic polyurethane) layer and a UV (ultraviolet) glue contact, wherein the keypad body, the glue layer, the TPU layer, the UV rubber contact, the polyester sheet and the metal spring sheet are arranged sequentially from top to bottom; the keypad body and the TPU layer are adhered to form a whole body through the glue layer under the action of pressure; the UV glue contact and the polyester sheet are adhered to form a whole body, and the polyester sheet provided with the UV glue contact is formed; the whole body formed by the keypad body, the glue layer and the TPU layer is in elastic contact with the polyester sheet provided with the UV glue contact; and the back surface of the polyester sheet is stuck to the metal spring sheet. The keypad has the following beneficial effects that as the UV glue contact directly serves as a silicone body in the conventional keypad body, the silicone body and related pretreatment are eliminated, so that the process is simplified, and the combined structure of the whole keypad is thinned; and the assembling process is simplified; moreover, the hand feel is good during the operation of the keypad; electrical performances of the keypad are stable and reliable; and the service life of the keypad is prolonged.
Description
Technical field
The utility model relates to the button that electronic product uses, and the integrated button of especially a kind of shrapnel contact is mainly used in mobile phone.
Background technology
The mobile phone of prior art, its button is the P+R structure, and two form is arranged.
Money one (see figure 1), comprise key body, A glue layer, contact silica gel, polyester sheet (generally claiming the PC sheet) and metal clips from top to bottom successively, key body is bonding under pressure by A glue layer and rubber-like contact silica gel, polyester sheet and metal clips are fitted, and contact silica gel and polyester sheet are Elastic Contact; Its process flow for assembling is: contact silica gel preliminary treatment---some glue forms the A glue layer on anchor clamps---with key body assembling pressing---integrated (with polyester sheet, metal clips combination).
Money two (see figure 2)s, comprise key body, B glue layer, TPU layer (polyester-type thermoplastic polyurethane from top to bottom successively, following identical), C glue layer, pet layer (polyethylene terephthalate, following identical), be coated with colloidal silica, polyester sheet and the metal clips of UV glue outward, key body is bonding under pressure by B glue layer and TPU layer, and the TPU layer is bonding under pressure by C glue layer and pet layer, and the colloidal silica and the pet layer that are coated with UV glue outward are bonding under pressure; Its process flow for assembling is: the colloidal silica preliminary treatment---colloidal silica is coated with UV glue outward---key body, B glue layer, TPU layer, C glue layer, pet layer and outer sticking mutually---UV adhesive curing---integrated (with polyester sheet, metal clips combination) of pressing of colloidal silica that is coated with UV glue.
All need the bonding of colloidal silica and glue layer in the conventional mobile phone press-key construction assembling of money one and money two.Cause the deficiency of at least two aspects: one, adhesion process is improper, causes defectives such as key body off normal, elastic force deficiency, dead key easily; Its two, operation is many, cost man-hour, human cost increases; Its three, the minimum thickness of colloidal silica has retrained the mobile phone products reduced thickness, is not suitable for using on the thin type mobile phone trend of incompatibility mobile phone thin typeization.
Summary of the invention
The utility model is intended to overcome the above-mentioned deficiency of prior art, provides a kind of shrapnel contact integrated button.Its designs simplification, assembling process is simplified, and pushes good hand touch, is beneficial to button integral thickness attenuate, and when pushing, shell fragment contacts with circuit board well, long service life.
For this reason, the technical scheme of the integrated button of the utility model shrapnel contact is as follows:
The integrated button of the utility model shrapnel contact, comprise key body, glue layer, polyester sheet and metal clips, also comprise TPU layer and UV glue contact, key body, glue layer, the TPU layer, UV glue contact, polyester sheet and metal clips set gradually from top to bottom, key body and TPU layer are whole by glue layer and bonding under pressure formation, UV glue contact and polyester sheet are bonding to be whole, form the polyester sheet of band UV glue contact, key body, the integral body that glue layer and TPU layer form is Elastic Contact with the polyester sheet of band UV glue contact, and paste mutually with metal clips at the back side of polyester sheet.
Technique scheme is further set forth:
Described UV glue contact is for putting the contact of the convex shape of UV glue through being solidified to form on polyester sheet.
The TPU layer is a polyester-type thermoplastic polyurethane film layer.
Compare with prior art, the beneficial effects of the utility model are: one, directly serve as colloidal silica in the conventional key body with UV glue contact, omit colloidal silica and relevant preliminary treatment, simplified technology, and attenuate whole key combination structure.Its two, packaging technology is simplified, during assembling, as long as with the polyester sheet and the shell fragment assembling of key body assembly, band UV glue contact, labour intensity alleviates, and is beneficial to reduce production costs.Its three, economical with materials.Its four, good hand touch during button operation, defectives such as key body off normal, elastic force deficiency and dead key no longer exist, the electric property of button is stable, reliable.Its five, useful life lengthening.
