Abstract
The utility model discloses an electrically conductive button that non - was pressed perpendicularly, including main part, slope connecting portion and the horizontal installation portion that integrated into one piece connects, horizontal installation position in the peripheral below of main part, the slope connecting portion are connected between main part and horizontal installation portion, and bottom surface an organic whole of this main part is extended to be had the support column and supports the belling ring, supports the periphery that the belling ring lies in the support column, and the bottom surface that should support the belling ring is the inclined plane, and this inclined plane is upwards extended to the outward flange slope by the inward flange, and the covering complex becomes to have the conducting layer on this inclined plane. By this, through will to the design of the bottom surface of belling ring for the inclined plane, when the finger is unilateral when pressing down the main part, the main part is movable downwards, this support column at first support press the PCB board on the surface and deformation takes place, then the bottom surface of conducting layer is encircled and is pushed down and laminate at the PCB board on the surface totally along with supporting the belling to form the face contact, replaced the mode of the point contact of tradition, thereby makeed electrical contact more reliable and more stable.
Description
Technical field
This utility model relates to button art, refers in particular to the conduction button of a kind of non-perpendicular pressing.
Background technology
Conductive rubber key industry is the industry being born in the eighties of last century 80-90 age.Almost all of electronic product all needs meritorious energy button.Silica gel push-button operation strategies is wide, such as telephone set, and computor-keyboard, remote controller, the electronic product containing types of functionality key such as controller.
Current conducting silica gel key bottom it all projection one compress bulge loop, this coated on bottom side compressing bulge loop is covered with conductive material, but, in prior art, this bottom surface compressing bulge loop is horizontal plane, when non-perpendicular pressing keys, owing to button can deform upon, the surface making the bottom surface and pcb board that compress bulge loop is only capable of forming point cantact, it is impossible to form face contact, so that reliability decrease.
Utility model content
In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide the conduction button of a kind of non-perpendicular pressing, and it can effectively solve the problem that existing conduction button reliability is bad.
For achieving the above object, this utility model adopts such as purgation technical scheme:
A kind of conduction button of non-perpendicular pressing, include the main part of one-body molded connection, tilt connecting portion and horizontal mounting portion, horizontal mounting portion is positioned at the peripheral lower section of main part, tilt connecting portion and be connected between main part and horizontal mounting portion, the bottom surface of this main part is integrally extended to be had support column and compresses bulge loop, compresses bulge loop and is positioned at the periphery of support column, and this bottom surface compressing bulge loop is inclined-plane, this inclined-plane is upwardly extended by the outside edge tilt of inward flange, and this inclined-plane overlying lid is formed with conductive layer.
As a kind of preferred version, the surface of described main part is formed with arc recess.
As a kind of preferred version, described support column is positioned at the bottom center of main part, and the bottom surface of support column is horizontal plane, and the level height of this horizontal plane is lower than the level height on inclined-plane.
As a kind of preferred version, described conductive layer covers to the medial surface and the lateral surface that compress bulge loop.
As a kind of preferred version, described conductive layer is carbon black material.
This utility model compared with prior art has clear advantage and beneficial effect, specifically, as shown from the above technical solution:
By being inclined-plane by the floor design compressing bulge loop, when the monolateral pressing main part of finger, main part is movable downwards, first this support column is pressed on the surface of pcb board and deforms upon, then, the bottom surface of conductive layer is pressed down and is fitted on the surface of pcb board completely with compressing bulge loop, thus forming face contact, instead of the mode of the point cantact of tradition, so that in electrical contact more reliable and more stable.
For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, this utility model is described in detail.

Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2, that show the concrete structure of the preferred embodiment of this utility model, include the main part 10 of one-body molded connection, tilt connecting portion 20 and horizontal mounting portion 30.
This main part 10, inclination connecting portion 20 and horizontal mounting portion 30 are silica gel material, horizontal mounting portion 30 is positioned at the peripheral lower section of main part 10, tilt connecting portion 20 and be connected between main part 10 and horizontal mounting portion 30, the bottom surface of this main part 10 is integrally extended to be had support column 11 and compresses bulge loop 12, compress bulge loop 12 and be positioned at the periphery of support column 11, this bottom surface compressing bulge loop 12 is inclined-plane, and this inclined-plane is upwardly extended by the outside edge tilt of inward flange, and this inclined-plane overlying lid is formed with conductive layer 40.
In the present embodiment, the surface of described main part 10 is formed with arc recess 13.Described support column 11 is positioned at the bottom center of main part 10, and the bottom surface of support column 11 is horizontal plane, and the level height of this horizontal plane is lower than the level height on inclined-plane.Described conductive layer 40 covers to the medial surface and the lateral surface that compress bulge loop 12, and described conductive layer 40 is carbon black material.
During use, this utility model is installed on the surface of pcb board 50, horizontal mounting portion 30 and the laminating of pcb board 50 surface, under initial condition, this main part 10 is suspended from the surface of pcb board 50, when the monolateral pressing main part 10 of finger 60, this main part 10 is movable downwards, and first this support column 11 is pressed on the surface of pcb board 50 and deforms upon, then, the bottom surface of conductive layer 40 is fitted on the surface of pcb board 50 with compressing 12 times pressures of bulge loop completely, thus forming face contact.
Design focal point of the present utility model is in that: by being inclined-plane by the floor design compressing bulge loop, when the monolateral pressing main part of finger, main part is movable downwards, first this support column is pressed on the surface of pcb board and deforms upon, then, the bottom surface of conductive layer is pressed down and is fitted on the surface of pcb board completely with compressing bulge loop, thus forming face contact, instead of the mode of the point cantact of tradition, so that in electrical contact more reliable and more stable.
The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every any trickle amendment, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the scope of technical solutions of the utility model.
