Abstract
The utility model provides a pushbutton device which comprises a pushbutton part and a connecting element; wherein, the pushbutton part is provided with a direction guiding slot; the corresponding position of the connecting element is provided with a guiding track; and the pushbutton part and the connecting element are matched and connected together through the gap arranged between the direction guiding slot and the guiding track of the part and the element. As the pushbutton part and the connecting element are matched and connected together through the gap arranged between the direction guiding slot and the guiding track and due to the direction guiding and positioning effects of the guiding track, when pushing down the pushbutton part, the pushbutton part only can straightforwardly slide along the guiding track, so as to avoid the phenomena of wearing and tearing and shaking caused by the deformation during the movement of the pushbutton part, thus improving the stability and safety of the pushbutton when in operation. At the same time, the service life of the pushbutton is further prolonged. Moreover, due to the positioning effect of the guiding track, the pushbutton part can be quickly and conveniently arranged on the connecting element through facing the direction guiding slot with the guiding track 7, thus greatly improving the work efficiency and reducing the undesired rate of the product production.
Description
Technical field
The utility model relates to a kind of key device, particularly relates to a kind of key device that is installed on the electronic installation panel.
Background technology
On the electronic installation panel, generally all can be provided with somely by strong, be used for pushing for the user, thus control mains switch or other functional select switch.This button must cooperate the position of mains switch or functional select switch usually and install, these mains switches or functional select switch on-line equipment are in the header board of electronic installation, and it is linked to each other with motherboard, thereby realize the setting of control power supply and electronic apparatus system function by electric wire.Because panel is covered on the header board, the button on the panel can touch mains switch or functional select switch on the header board after being subjected to the pushing of user, thereby realizes the switch of power supply or to the setting of electronic apparatus system function.Existing press-key structure as shown in Figure 1, it comprises key main body 1, elastic arm 2, fastening structure 3 and location structure 4.At first button is positioned at the relevant position of electronic installation panel during work by location structure 4, by fastening structure 3 it is fastened on the electronic installation panel again, when pressing main body 1, strain takes place in elastic arm 2, make that main body 1 is (not shown at circuit board, hereinafter to be referred as PCB) on switch impulse stroke (be the switch nature by the distance between the down state) fully in motion, thereby finish the open/close operation of switch.It is simple in structure for this button, mould is easy to manufacture, stay in grade.But, be difficult for the mating holes center during installation, thereby influence operating efficiency because button is to locate by the hole on the location structure 4.In installation process, also be easy to generate off-centre simultaneously.In addition, above-mentioned button is the operation that realizes button by elastic arm 2 distortion, and long-term the use then easily produce and rock instability.
Summary of the invention
In order to overcome the technical deficiency that existing button is installed difficulty, job insecurity, easily rocked, the utility model provides a kind of stable operation, safe and reliable, and the key device that makes things convenient for quick for installation.
The technical solution of the utility model is to realize like this, a kind of key device, described key device comprises button portion, connector, described button portion is provided with gathering sill, the correspondence position of described connector is provided with guide rail, and described button portion and connector are connected by gathering sill and the guide clearance of establishing thereon.
Adopt key device of the present utility model, because between button portion and the connector is to be connected by gathering sill and the guide clearance of establishing thereon, when pushing button portion, because the guiding and the positioning action of guide rail, make button portion to do linear slide along guide rail, thereby bad phenomenon such as avoided button portion when motion to cause wearing and tearing because of distortion and to rock has improved the stability and the fail safe of button work.Simultaneously, also prolonged the useful life of button.In addition,, during installation, only need that gathering sill is aimed at guide rail and just can quickly and easily button portion be installed on the connector, improved operating efficiency greatly, reduced the production fraction defective because the positioning action of guide rail is arranged.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
To shown in Figure 4, be a preferred embodiment of the present utility model, a kind of key device with reference to Fig. 2, it comprises: button portion 1 and connector 2, described button portion 1 is provided with button 3 and body 4, also is provided with two external parts 5 on described body 4, and external part 5 is provided with V-type gathering sill 6; Described connector 2 is used for key device is fixedly connected on electronic installation, and it can be the housing or the panel of electronic installation, also can be independent connector.The correspondence position of described connector 2 is provided with V-type rail 7, and described connector 2 is connected with gathering sill 6 matched in clearance by guide rail 7 with button portion 1.When the portion 1 of pushing button, because the guiding and the positioning action of guide rail 7, make button portion 1 to do linear slide, thereby cause wearing and tearing because of distortion when having avoided button portion 1 motion and bad phenomenon such as rock, improved the stability and the fail safe of button work along guide rail 7.Simultaneously, also prolonged the useful life of button.In addition,, during installation, only need that gathering sill 6 is aimed at guide rail 7 and just can quickly and easily button portion 1 be installed on the connector 2, improved operating efficiency greatly, reduced the production fraction defective because the positioning action of guide rail 7 is arranged.
In order to make better fit between above-mentioned gathering sill 6 and the guide rail 7, the slope of described gathering sill 6 and two V-structures of guide rail 7 should be identical, and the direction unanimity, and promptly contact-making surface is parallel.In addition, as shown in Figure 5, the monolateral fit-up gap X between gathering sill 6 and the guide rail 7 preferably is controlled between 0.1～0.2mm.Because if still can there be rocking by a small margin in excesssive gap, button; If the gap is too small, " stuck " phenomenon then appears easily.The value of the length Y of " V " font structure also should minimum be not less than 4mm simultaneously, to guarantee effective contact length and effective contact area.Certainly, above-mentioned gathering sill 6 also can be rectangle or trapezoidal other shape that waits with the shape of guide rail 7.
