Description
Affiliated technical field
The utility model relates to a kind of button, relates in particular to a kind of gummed location structure of button.
Background technology
At present, mobile phone, computer, PDA 3C Product (Communication, Computer, Consumer such as (personal digital assistants), be the abbreviation of communication product, computer product, consumer electronics product) be used in the daily life just more and more, and become the essential of people's daily life day by day.
Above-mentioned existing 3C Product generally all has a key system, this key system generally includes keycap, bracing frame, elastomer, film circuit board and the base plate of from top to bottom arranging, wherein elastomer and film circuit board are glued together, can ease of assembly and use.
Yet, in the gummed process of above-mentioned elastomer and film circuit board, when a glue amount is big, tend to produce the glue phenomenon of overflowing, thereby reduced the yield of product, and influence the assembling and the use of described key system.In addition, produce dislocation when preventing to glue together, need between elastomer and film circuit board to position by special localization tool, thereby make assembling prolong man-hour, and need extra cost, manufacturing cost is higher.
The utility model content
Main purpose of the present utility model provides a kind of gummed location structure of button, can avoid the generation of excessive glue phenomenon.
Another purpose of the present utility model provides a kind of gummed location structure of button, need not to use localization tool can finish assembling, thereby improves packaging efficiency, saves assembly cost.
For realizing above-mentioned main purpose, the utility model provides a kind of gummed location structure of button, comprises elastomer and is positioned at the film circuit board of elastomer below.Wherein, this elastomer glues together mutually with this film circuit board, and described elastomer also has a body.It is characterized in that: this elastomeric body upwards is recessed to form an endless groove in lower surface, accommodates elastomer and film circuit board gummed unnecessary glue during operation.
For realizing above-mentioned another purpose, the utility model provides a kind of gummed location structure of button, and wherein said film circuit board has a substrate.This substrate upwards protrudes out formation one in upper surface and locatees wall with the ring-type that described elastomeric endless groove is complementary, and this ring-type location wall upwards is embedded in this endless groove.
As mentioned above, unnecessary glue when the utility model is accommodated the operation of elastomer and film circuit board gummed by endless groove, the generation of the glue phenomenon of can avoiding overflowing; Upwards be embedded in the endless groove by ring-type location wall, one location structure can be provided, make the utility model need not to use localization tool can finish the assembling of elastomer and film circuit board, thereby raising packaging efficiency, save assembly cost, also effectively increase fitting area and intensity between elastomer and the film circuit board simultaneously.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
The gummed location structure 1 of the utility model button is applied to the key system of 3C Products such as mobile phone, computer, PDA, this key system generally includes keycap, bracing frame, elastomer, film circuit board and the base plate of from top to bottom arranging, wherein elastomer and film circuit board are glued together.
See also Fig. 1, in first embodiment of the present utility model, the film circuit board 20 that this gummed location structure 1 comprises elastomer 10 and is positioned at elastomer 10 belows and glues together with it, this film circuit board 20 also is flat tabular.
Please cooperate Fig. 2, elastomer 10 has a body 11, and body 11 lower surfaces upwards are recessed to form an endless groove 12 at a certain distance.
Please cooperate and consult Fig. 3, during assembling, elastomer 10 is placed horizontally in the localization tool, the surface of offering endless groove 12 is made progress, and go up an amount of glue in this surperficial endless groove 12 inboard points, and make elastomer 10 and film circuit board 20 glued together by localization tool then, elastomer 10 and the film circuit board 20 that will finish gummed at last reverse up and down, make elastomer 10 be positioned at film circuit board 20 tops, then both the veneer of the two formation can be assembled in the aforementioned keys system.
In above-mentioned gummed operation process, when a glue amount was big, the surplus glue that is produced flowed in the endless groove 12, has avoided the generation of excessive glue phenomenon thus.
See also Fig. 4, the difference of the utility model second embodiment and first embodiment is: film circuit board 20 has a substrate 21, and substrate 21 upper surfaces upwards protrude out formation one and locate wall 22 with the ring-type that endless groove 12 is complementary.
Please cooperate and consult Fig. 5, second embodiment of the present utility model with elastomer 10 horizontal positioned, makes progress the surface of offering endless groove 12 when assembling, and goes up an amount of glue in these surperficial endless groove 12 inboard points.Then the ring-type location wall 22 of film circuit board 20 is aimed at endless groove 12 and insert, described ring-type location wall 22 is contained in the endless groove 12.The glue that smear by the medial surface of elastomer 10 this moment can be one with film circuit board 20 and elastomer 10 gummeds.Elastomer 10 and the film circuit board 20 that to finish gummed at last reverse up and down, make elastomer 10 be positioned at film circuit board 20 tops, then both the veneer of the two formation can be assembled in the aforementioned keys system.
In above-mentioned gummed operation process, when a glue amount was big, endless groove 12 was also accommodated glue unnecessary when gluing together operation, thereby has avoided the generation of excessive glue phenomenon.In addition, the location structure design that the utility model matches with ring-type location wall 22 by above-mentioned endless groove 12, do not need to use localization tool can finish the assembling of elastomer 10 and film circuit board 20, thereby improved packaging efficiency, save assembly cost, also effectively increased fitting area and intensity between elastomer 10 and the film circuit board 20 simultaneously.
