Abstract
A switch structure includes an inner/outer circle helical spring which is a flexible component provided between a button and a switch body, when the button is pressed by a force larger than the elasticity of the flexible component, the flexible component make the switch be pressed and in an ON state; when the button is pressed by a force less than the elasticity of the flexible component, the switch body is not in the ON state, wherein, the inner/outer circle helical spring is a component that when the button is pressed, the switch is pressed, and is a component that when the switch is not pressed, a component for pressing the switch is detached from the switch. The switch has a small number of components and a small work time for being assemblied.
Description
Technical field:
The present invention relates to the starting switch of a kind of structure of switch, particularly weighing instrument.
Background technology: the switch of prior art, the starting switch of weighing instrument particularly, open as described in the flat 8-313334 patent documentation as the spy, a shroud member and a helical spring have been adopted, wherein, shroud member is arranged between Switch main body and the button, and when pressing the button, shroud member produces the elastic force of pressing switch; Helical spring also is arranged between Switch main body and the button, and when button was not pressed, shroud member was not pressed switch, thereby button is in the state of not pressing switch.
In the construction of switch of prior art, between Switch main body and button, adopted the member of pressing switch and made this member break away from the member of switch, promptly adopted two members, therefore, the problem that runs into is that the number of part is many, and assembling is also long man-hour.
Summary of the invention:
In the present invention, adopt an Internal and external cycle helical spring, it is arranged between Switch main body and the button, is the member of pressing switch, is again to make the member of pressing switch break away from the member of switch when not pressing switch.
In switch of the present invention, between Switch main body and button, be provided with an Internal and external cycle helical spring, an end of its path part contacts with the top of switch, and the linking part of the other end contacts with button, to press switch; The end that the helical spring large-diameter portion of this Internal and external cycle divides contacts with the installing component of Switch main body, and the other end contacts with button, so that button can break away from switch.The length of the helical spring large-diameter portion branch of Internal and external cycle and the length of path part are to set like this, do not do the time spent when button is not subjected to external force that is:, and the helical spring path part of Internal and external cycle is not according to following switch.
Description of drawings:
Fig. 1 is the structural representation according to switch of the present invention;
Fig. 2 A and 2B show employed spring in switch of the present invention;
Fig. 3 A and 3B show the switch of prior art and the spring that is adopted; And embodiment:
Fig. 4 A and 4B show another one embodiment of the present invention.
Below in conjunction with accompanying drawing embodiments of the invention are described.Fig. 1 is the structure section figure of switch of the present invention, and Fig. 2 shows the spring that uses in switch of the present invention, and Fig. 3 shows the switch of prior art and the spring that is adopted, and Fig. 4 shows another one embodiment of the present invention.
In the switch module 101 of prior art, as shown in Figure 3, two members between button 106 and Switch main body 107, have been adopted, i.e. helical spring 104 and shroud member 103, helical spring 104 is to make button break away from the part of Switch main body, and shroud member 103 is parts of pressing Switch main body.When pressing the button when having overcome helical spring elastic force, the front end of shroud member is resisted against on the head of switch, and switch just is in the state of ON; When the power that presses the button is 0 or during less than helical spring elastic force, even shroud member contacts with the head of switch, switch also remains on the OFF state.Fig. 3 A is decomposing state figure, and Fig. 3 B is the installation diagram of switch.
In construction of switch according to the present invention, shown in the switch module among Fig. 11, two members (helical spring and shroud member) that switch module adopted of prior art have been replaced by an Internal and external cycle helical spring 2.As shown in Figure 2, helical spring path part 3 of Internal and external cycle and large-diameter portion divide 4 with the contacted side of button be integrated linking part 5.Shown in Fig. 2 A, it all is the column type helical spring that helical spring path part of Internal and external cycle and large-diameter portion divide, shown in Fig. 2 B, described path part and large-diameter portion branch can be the circular cone type helical springs, in another one embodiment shown in Figure 4, column type helical spring and circular cone type helical spring are used in combination.
Fig. 1 presses the button 6 to make Switch main body 7 be in the state diagram of ON state.Switch main body 7 is installed on the substrate 8, is provided with guide 9 around Switch main body 7, and this guide 9 maintains gap 22 with Switch main body 7, and guide 9 is the action stop of button 6, is again the helical spring guider of Internal and external cycle.Be provided with shell 10 in the outside of guide 9, this shell 10 is the stops that prevent that button from moving outward.Has space 21 in the inboard of button, to hold the helical spring linking part 5 of Internal and external cycle; Be provided with flange 12 in the outside of button, this flange 12 can with pawl 11 coordinations of shell 10, break away from mutually to prevent button and shell.
The end 13 that the helical spring large-diameter portion of Internal and external cycle divides is installed in the gap 22 between guide 9 and the Switch main body 7, and the helical spring linking part 5 of Internal and external cycle is installed on the button 6, shell 10 is sleeved on the button, and the mounting jaw 14 of shell is fixed in the hole (not shown) of substrate.When not having external force to act on the button, the helical spring large-diameter portion branch of Internal and external cycle is resisted against on the pawl 11 of shell 10 at the flange 12 that makes button under the effect of elastic force, and between the top of the end 15 of the helical spring path part of Internal and external cycle and switch certain clearance being arranged, switch can not contact to the degree that reaches the ON state.
In the another one embodiment of the present invention shown in Fig. 4 A and the 4B, switch is installed on the template 16,17 of substrate, and in addition, the template 17 of substrate has produced electric connection.Under the situation of present embodiment, the Internal and external cycle helical spring all is the member of conduction.The helical spring linking part 19 of Internal and external cycle is installed on the button (not shown), when pressing the button, the end 20 of the helical spring path part of Internal and external cycle contacts with the template 16 of substrate, two templates 16,17 of substrate are by the Internal and external cycle helical spring and electric connection makes switch be in the ON state.In addition, the minor diameter part branch is installed on the substrate, when pressing the button, large-diameter portion is divided contact with template.Although do not illustrate among the figure, the present embodiment also situation with shown in Figure 1 is the same, is provided with the part of corresponding necessity such as shell, guide.
As mentioned above, in the present invention, partly press switch, make button break away from Switch main body, only just realized the action of two parts with a part with its large-diameter portion branch with a helical spring path of Internal and external cycle.
The structure of switch of the present invention has been described above, in this structure, the decreased number of part, and assemble and also can reduce man-hour.
