Abstract

The utility model discloses a band switch. A positioning slot of a positioning mechanism of a movable contacting piece is arranged on the hole wall of an inner hole of a bracket, a pressing spring and a spring are arranged in a positioning hole of a rotating disk. A static contacting piece which is made of monolayer copper sheet is fixed in the groove of the plane of the bracket, and the movable contacting piece is composed of two-layers of copper sheets and forms a holding hole. The design of the band switch makes the number of the component parts are reduced, and the band switch has the advantages of material saving, simple structure and convenient assemblage, and the moveable and static contacting pieces works reliable and are hard to damage.

Description

Band switch

The utility model relates to a kind of band switch of being made up of movable contact spring and some static contacts of being provided with around the movable contact spring.

The movable contact spring of this band switch is the individual layer copper sheet, is fixed on the rotating disk, and rotating disk drives rotation by rotating shaft; Static contact is double-deck copper sheet, and riveted is forming the rank mouth structure at the plane of support Shang ， And with the movable contact spring rank place of closing; In addition, movable contact spring has detent mechanism, is made up of location notch, pellet shot from a slingshot and pressure spring plate, and wherein location notch is located on the location-plate, and location-plate is rack-mount by connector.There is following shortcoming in the band switch of this structure: at first be cannot say for sure to demonstrate,prove static contact on the technology rank mouth place at grade, like this, when movable contact spring rotated, the rank mouth with static contact destroyed easily; Next is that the static contact of riveted on the support plane very easily overlaps with contiguous static contact because of the not firm ， of the swinging And of riveted easily; The 3rd is that location-plate and support become flexible because of connector easily or rigging error causes both relative positions variations, and makes the movable contact spring location inaccurate, quiet, movable contact spring loose contact.

The utility model is intended to overcome above-mentioned shortcoming, provides a kind of use reliable, band switch simple in structure.

Solving main points of the present utility model is that static contact is the individual layer copper sheet, and movable contact spring is that double-deck copper sheet ， And forms the rank mouth that closes with the static contact rank; The support plane is provided with for the groove of placing static contact, and the support inner hole wall is provided with location notch, and And constitutes the movable contact spring detent mechanism together with the stage clip and the pellet shot from a slingshot that are installed in the rotating disk.

This specification provides following accompanying drawing:

Fig. 1: the utility model rearview;

Fig. 2: the A-A cutaway view of rearview

Fig. 3: the rearview of support;

Fig. 4: the sectional view of rotating disk.

Accompanying drawing has been described a kind of embodiment of the present utility model, introduces content of the present utility model below in conjunction with accompanying drawing.

The utility model is assembled by support (1), rotating disk (2), rotating shaft (3), jump ring (4), movable contact spring (5), static contact (6), nut (7), stage clip (8), pellet shot from a slingshot (9) and handle (17).Support (1) has plane and stepped hole, and uniform groove (10) is arranged on the plane, and the aperture in the stepped hole is the shaft hole of supporting shaft (3), and macropore is a turret apertures, and hole wall is provided with location notch (11), and a quiet guide vane end stop (12) is arranged at the bottom of the hole.Movable contact spring (5) is made up of two-layer copper sheet, and (2) Shang ， And form rank mouthful (14) to be fixed on rotating disk by the riveting pin (13) on the rotating disk (2).Static contact (6) is the individual layer copper sheet, is installed in by rivet in the groove (10) of support (1), and static contact (6) has the long and short two kind, and wherein long static contact (6) is a slice only, and same movable contact spring (5) is held in the mouth all the time and closed, and is the pinout connector of movable contact spring (5).The same rotating shaft of rotating disk (2) (3) forms firmly and connects, rotating disk (2) is provided with two location holes (15) and a moving guide vane end stop (16), place stage clip (8) and pellet shot from a slingshot (9) in the location hole (15), location notch (11) on the same support (1) constitutes the movable contact spring detent mechanism together, and the quiet guide vane end stop (12) on the moving same support of guide vane end stop (16) (1) constitutes the movable contact spring position limiting structure together.Handle (17) is enclosed within the rotating shaft (3), is fixed by screw, and the effect of jump ring (4) is the fixing axial location of rotating disk assembly.

The band switch of said structure, location notch and static contact groove are arranged on the same part, again stage clip and pellet shot from a slingshot are set directly on the rotating disk, this not only makes band switch omit location-plate, pressure spring plate, the pellet shot from a slingshot frame, metal partss such as connector, simplify the structure and assembly technology, also make the accurate positioning in the movable contact spring rotation process, guarantee that movable contact spring closes with the rank fully of static contact, in addition, groove can further prevent swinging of static contact, static contact changes individual layer Tong Pian And into cancelled static contact rank mouthful after, adjust the relative position of all static contacts easily, the thickness of copper sheet also can be thickeied, increase the rigidity and the intensity of static contact, make, the work of static contact is more reliable, therefore, the utlity model has simple in structure, material is saved, and assembling is easy, reliable operation, advantage such as not fragile is the new product that band switch updates.

Claims

1, a kind of band switch, by support, rotating disk, rotating shaft, handle and be fixed on the movable contact spring on the rotating disk and Pai Lie And is arranged on the support around the movable contact spring some static contacts constitute, wherein having a static contact to hold in the mouth all the time with movable contact spring closes, in addition, also have by location notch, movable contact spring detent mechanism that stage clip and pellet shot from a slingshot are formed and the movable contact spring position limiting structure of forming by moving guide vane end stop and quiet guide vane end stop, of the present utility model being characterised in that: uniform groove (10) on the plane of support (1), the static contact (6) that the individual layer copper sheet is made is fixed in the groove (10), location notch (11) is arranged on the endoporus hole wall of support (1), one quiet guide vane end stop (12) is arranged at the bottom of the hole, moving contact (5) is formed And by two-layer copper sheet and is formed rank mouthful (14), rotating disk (2) is provided with two location holes (15) and a moving guide vane end stop (16), and stage clip (8) and pellet shot from a slingshot (9) are contained in the location hole (15).
