Abstract
The utility model relates to a reed device of a microswitch. The reed device comprises a reed support and a reed, the reed support is provided with a reed positioning clamping seat and an elastic piece clamping seat, both the reed positioning clamping seat and the elastic piece clamping seat are folded to form double-layer boards, the outer edges of the double-layer boards sink inwards to form a reed positioning clamping groove for clamping the reed and an elastic piece clamping groove for clamping an elastic piece, and the tail end of the reed is also folded to be of a double-layer structure. Under the condition where manufacturing techniques of the conventional reed device do not change, the folded structures are added to key stressing parts so as to enhance the strength, improve the quality of the reed support, and prolong the service life. The structure of the reed device is very simple, and reinforcement of the reed device can be realized without changing conventional manufacturing equipment or manufacturing techniques of the reed devices. With the structural improvements, the thickness of easy-to-wear parts of the reed support and the reed is raised, the frictional force born by the reed support and the reed are dispersed, and abrasive resistance between the reed support and the reed is enhanced.
Description
Technical field
The utility model relates to a kind of leaf arrangement of sensitive switch.
Background technology
Sensitive switch is to have small contact separation and fast actuation mechanism, the contact mechanism that carries out switch motion by the stroke of regulation and the power of regulation.Outer mechanical force by power effect and action reed, when action reed produces instantaneous operation while being displaced to critical point, makes to move moving contact and fixed contact quick-make or the disconnection of reed end by actuated element.Sensitive switch on domestic market difference according to requirements, the mechanical endurance of switch is not by 100,000 times to 5,000 ten thousand times etc., this just proposes very high wear-resisting requirement to the leaf arrangement in sensitive switch, and leaf arrangement of the prior art is all generally the disposable drawing of single sheet, resistance to wear is poor.
Utility model content
In order to overcome the deficiencies in the prior art, the sensitive switch leaf arrangement that provides resistance to wear strong is provided the purpose of this utility model.
For addressing the above problem, the technical scheme that the utility model adopts is as follows: a kind of leaf arrangement of sensitive switch, comprise leaf support and reed, leaf support is provided with reed location deck and flexure strip deck, reed location deck and flexure strip deck position are all folded to form doubling plate, and the outer ledge of doubling plate caves inward and is formed for blocking the reed locating groove and the flexure strip draw-in groove that blocks flexure strip of reed.
Reed location deck can be doubling from top to bottom from top with the doubling mode at flexure strip deck position, can be also by side left or the direction on the right side to carry out doubling be double-decker.
In the process by stamped from sheetstock leaf support, by the sheet material at reed locating groove position and flexure strip draw-in groove position first respectively doubling be double-decker, and then carry out the punching press of two draw-in grooves, double-deck draw-in groove thickness has increased by one times, resistance to wear is also strengthened greatly, and first doubling again the mode of punching press can guarantee the evenness of draw-in groove, tighter when reed or flexure strip and draw-in groove clamping, the sensitivity of micromotion mechanism is higher.
Because the thickness of the draw-in groove of leaf support has increased, so the bayonet socket of corresponding reed also must be widened and could use with support assorted, due to the contact area increase of bayonet socket and draw-in groove, disperse frictional force, make support and reed more wear-resisting.
The inside reflexed of tail end of reed is double-decker, and reed tail end is position the most easy to wear, so rolled over the abrasive resistance that increases reed for double-decker.
Preferred: the sheet thickness of punching press leaf support and reed is 0.5mm, after draw-in groove position and the doubling of reed tail end, thickness is 1mm.
Compared to existing technology, the beneficial effects of the utility model are: in the manufacture craft situation that does not change existing switch spring device, to crucial force part, by increasing folded structure, increase its intensity, to improve the quality of leaf support, extend its useful life.This structure is very simple, and does not need the equipment of existing manufacture leaf arrangement to transform, and also need not change its manufacturing process, just can realize the strengthening of leaf arrangement.This structure of modification, has strengthened the thickness at leaf support and reed position easy to wear, disperses its frictional force of bearing, and has strengthened both resistance to wears.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of leaf arrangement of sensitive switch, comprise leaf support 7, reed 8, leaf support 7 is provided with reed location deck 10 and flexure strip deck 9, reed location deck 10 is all folded to form doubling plate with the pressing sheet material at flexure strip deck 9 positions, and the outer ledge of doubling plate caves inward and is formed for blocking the reed locating groove 2 and the flexure strip draw-in groove 1 that blocks flexure strip 3 of reed 8, and then punching press draw-in groove, guarantee the smooth of draw-in groove position, the thickness of draw-in groove has been thickeied in doubling.As can be seen from Figure 4, flexure strip 3 one end and reed 8 connect as one, and the other end is that free end is connected in flexure strip draw-in groove 1.
The corresponding reed 8 being used in conjunction with improved support 7 also needs reed bayonet socket 5 and flexure strip bayonet socket 6 to widen, the draw-in groove of bayonet socket width and thickening is adapted, the draw-in groove that thickness increases and the bayonet socket of widening have increased the contact area of flexure strip 3 and reed 8 and support, disperse frictional force, support 7 and the resistance to wear of reed 8 are strengthened.
Above-mentioned execution mode is only preferred implementation of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
