Description
Technical field
The utility model relates to a kind of electric elements, particularly relates to a kind of diverter switch big current moving contact group.
Background technology
Diverter switch is a kind of conventional low-voltage electrical apparatus, generally include change over switch, isolating switch, duplicate supply etc., and the key element of this switch is moving contact group.Traditional moving contact group adopts bridge-type list contact usually, be improved to the two contact of bridge-type afterwards, now column type moving contact group is also had to occur, the employing helical spring that spring mechanism in moving contact group has, some employing arch bridge-type springs, bridge-type moving contact group generally adopts copper sheet, it is point cantact when contacting with fixed contact, its electric conductivity and heat dispersion very poor, described arch bridge-type spring is owing to requiring very high to materials and process, difficult quality guarantee, due to the appearance of these defects, seriously constrains the development of diverter switch particularly high-power diverter switch.
Summary of the invention
The purpose of this utility model is the many disadvantages overcoming existing diverter switch moving contact group, discloses a kind of big current moving contact group of stable performance.
The technical solution adopted in the utility model is: a kind of diverter switch big current moving contact group, it is characterized in that: it comprises contact pedestal, multiple contact hoop lid, many helical springs, multiple spring bearer plate, multiple moving contact group, described contact pedestal is equidistantly provided with along side, front and back two and organizes perforate more, the mid portion of described perforate is set to moving contact mount pad, described moving contact mount pad and described contact pedestal are connected as a single entity, two semicircles are respectively had at the upper and lower of described moving contact mount pad, semicircle above described moving contact mount pad is built with two moving contacts, semicircle below described moving contact mount pad is built with two moving contacts, the upper edge of two moving contacts is provided with a spring bearer plate up, described spring bearer plate is provided with helical spring, described moving contact, spring bearer plate, helical spring held by a contact hoop lid, contact hoop lid baffle plate is provided with in two sides of described perforate.
Further setting, described moving contact is cylinder, and two ends of moving contact extend to contact pedestal outside, and described moving contact two end cylinder is larger, interlude cylinder is less, and its interlude cylinder radius is identical with the semicircle radius of described moving contact mount pad upper and lower.
Further setting, described contact hoop lid is rectangle, below the top of contact hoop lid, be provided with spring fitting load bearing seat, the bottom of contact hoop lid is set to two semicircular moving contact bayonet sockets, and moving contact bayonet socket half radius of a circle is identical with the cylindrical radius of described moving contact mid portion.
The beneficial effect that the diverter switch big current moving contact group of above structure has is: owing to have employed cylinder moving contact, insert for rolling when in diverter switch, its moving contact enters fixed contact, the contact position of moving contact and fixed contact is linear contact lay simultaneously, the contact position wearing and tearing of dynamic and static contact are reduced, contact resistance reduces, have employed four moving contacts simultaneously, what substantially increase diverter switch spends properties of flow and useful life, owing to have employed contact hoop lid and sheathed helical spring, make moving contact group working stability and structure is simple, be easy to manufacture and assembling.

Embodiment
Composition graphs 1 ~ Fig. 6, by specific embodiment, is suitable for novel being described further to this.
A kind of diverter switch big current moving contact group, it is characterized in that: it comprises contact pedestal 1, multiple contact hoop lid 2, many helical springs 3, multiple spring bearer plate 4, multiple moving contact group 5, described contact pedestal 1 is equidistantly provided with the perforate 102 of many groups along side, front and back two, 104, the mid portion of described perforate is set to moving contact mount pad 103, described moving contact mount pad 103 is connected as a single entity with described contact pedestal 1, two semicircles are respectively had at the upper and lower of described moving contact mount pad 103, semicircle above described moving contact mount pad 103 is built with two moving contacts 501, semicircle below described moving contact mount pad 103 is built with two moving contacts 502, the upper edge of two moving contacts 501 is provided with a spring bearer plate 4 up, described spring bearer plate 4 is provided with helical spring 3, described moving contact 5, spring bearer plate 4, helical spring 3 held by a contact hoop lid 2, in described perforate 102, two sides of 104 are provided with contact hoop lid baffle plate 101.
Further setting, described moving contact 5 is cylinder, and two ends of moving contact 5 extend to the outside of contact pedestal 1, and two end cylinders of described moving contact 5 are larger, interlude cylinder is less, and its interlude cylinder radius is identical with the semicircle radius of described moving contact mount pad 103 upper and lower.
Further setting, described contact hoop lid 2 is rectangle, spring fitting load bearing seat 201 is provided with below the top of contact hoop lid 2, the bottom of contact hoop lid 2 is set to two semicircular moving contact bayonet sockets 202, and moving contact bayonet socket 202 half radius of a circle is identical with the cylindrical radius of described moving contact 5 mid portion.
