Abstract
The utility model discloses a button switch for preventing blockage, which belongs to a button switch and aims at providing a button switch for preventing clamping stagnation or blockage. The button switch comprises a base, an executing mechanism and a contact assembly, wherein the executing mechanism and the contact assembly are arranged in the base; the base comprises an outer base (14) and an inner base (10); the executing mechanism comprises a button (2) arranged in the inner base (10), a push rod (1) fixedly connected with the button, a small spring (6) and a steel ball (5) which are arranged in a blind hole (16), a ferrule (4) fixedly sleeved on the push rod (1), and a spring (9) arranged on the push rod (1); and the contact assembly comprises a contact body (11) fixed at the lower end of the push rod (1), and a plurality of spring contacts (12) fixed in the outer base (14). The button switch has the advantages of simple structure, convenience for processing, low manufacture cost, reliable performance and the like, and is suitable for being used by various kinds of appliances.
Description
Technical field
The utility model relates to a kind of push-button switch, relates in particular to a kind of anti-stuck push-button switch.
Background technology:Push-button switch is a kind of axial linear drives switch, is the control element of each quasi-instrument, instrument, electromechanical equipment; Usually by be located in the pedestal hold actuation mechanism and contact assembly constitutes.The actuation mechanism of holding of conventional button switch is that spigot surface is done axial motion with the inwall of pedestal mostly, for fear of stuck phenomenon occurring, just must guarantee that base internal wall quality of fit smooth, that hold between actuation mechanism and the base internal wall is higher; Not only increase difficulty of processing, and strengthened manufacturing cost.
Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aim to provide a kind ofly be convenient to process, the anti-stuck push-button switch of reliable in action.
To achieve these goals, the utility model adopts following technical scheme: it comprises pedestal, be located at and hold actuation mechanism and contact assembly in this pedestal; Said pedestal is made up of outer seat, the interior seat that is fixed in this outer seat; Said hold actuation mechanism by the button in the seat in being located at, with this button is fixedly connected and has blind hole push rod, be located at little spring and steel ball in the blind hole, fixed cover and constitute at the lasso that compresses on the push rod and with steel ball, the spring that is located on the push rod, said contact assembly by the hemisphere contact that is fixed on the push rod lower end, be arranged in around this contact and be fixed on outside a plurality of spring contact strips constitute.
On said pedestal, be fixed with screwed shell.
Compare with prior art; The utility model is owing to adopted technique scheme; On the basis of conventional button switch, increased little spring and steel ball, utilized the rolling of steel ball to reduce friction, therefore not only thoroughly avoided holding actuation mechanism and in pedestal, done axial motion and occur clamping stagnation or stuck phenomenon easily; But also can reduce the machining accuracy of base internal wall and hold actuation mechanism and base internal wall between quality of fit, cut down finished cost significantly.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: seat 10 contacts 11 spring contact strips 12 collars 13 outer seat 14 packing rings 15 blind holes 16 in push rod 1 button 2 shells 3 lassos 4 steel balls 5 little springs 6 locking nuts 7 elastic washers 8 springs 9
Embodiment:Below in conjunction with accompanying drawing and concrete embodiment the utility model is described further:
As shown in Figure 1: interior seat 10 is fixedly connected to form pedestal through screw thread and outer seat 14.In interior seat 10, be provided with the push rod 1 that is fixedly connected and has blind hole 16 by button 2, with this button, be located at little spring 6 and steel ball 5 in the blind hole 16, fixed cover is at the lasso 4 that compresses on the push rod 1 and with steel ball 5 and be located at the actuation mechanism of holding that spring 9 on the push rod 1 constitutes; Lasso 4 is provided with the location hole that can supply steel ball 5 to expose.Seat has contact assembly in 14 outside, and this contact assembly constitutes by be fixed on a plurality of spring contact strips 12 that push rod 1 lower end is hemispheric contact 11, is arranged in around this contact and is fixed on outer seat 14 through collar 13.For the ease of installing, screwed shell 3 is pressed on the interior seat 10 through screw thread by outer seat 14; For fear of loosening, be provided with elastic washer 8 between seat 14 and the shell 3 outside.
During use, shell 3 is passed the installing hole on the mounting panel (not shown), through packing ring 15 and locking nut 7 the utility model is clamped on the said mounting panel then and gets final product.
