Description
Technical field
The utility model relates to a kind of electric elements, particularly relates to a kind of diverter switch 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-compressed 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 constrain 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 moving contact group of stable performance.
The technical solution adopted in the utility model is: a kind of diverter switch moving contact group, it is characterized in that: it comprises contact pedestal, multipair moving contact, multiple helical spring, multiple contact anchor ear, described contact pedestal is equidistantly provided with along side, front and back two and organizes perforate more, described perforate is made up of upper perforate and lower perforate, be separated by for insulating in contact pedestal between described upper perforate and lower perforate, the bottom of perforate and the top of lower perforate are set to semicircle on described, a big groove is vertically installed with along contact pedestal top and the bottom at described tapping, two sides of big groove are provided with two little grooves, moving contact on one is provided with on described in perforate, a lower moving contact is provided with in described lower perforate, the contact anchor ear of an oval type is had in the arranged outside of described two moving contacts, be close to identical on the lower edge of described contact anchor ear and the lower edge of lower moving contact, two described little grooves are close in two sides of contact anchor ear, a helical spring is arranged with in opening joining place on contact anchor ear top, described helical spring is pressed on the upper edge of moving contact, the big groove limit of described contact pedestal is close in helical spring outside.
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 the semicircle that the bottom of its interlude cylinder radius and described upper perforate and the top of lower perforate are arranged coincide mutually.
The beneficial effect that the diverter switch 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, substantially increase electric conductivity and the useful life of diverter switch, simultaneously owing to have employed contact anchor ear 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. 5, by specific embodiment, is suitable for novel being described further to this.
A kind of diverter switch moving contact group, it is characterized in that: it comprises contact pedestal 1, multipair moving contact 4, multiple helical spring 2, multiple contact anchor ear 3, described contact pedestal 1 is equidistantly provided with the perforate 106 of many groups along side, front and back two, described perforate 106 is made up of upper perforate 103 and lower perforate 105, 104 to be separated by for insulating in contact pedestal between described upper perforate 103 and lower perforate 105, the bottom of perforate 103 and the top of lower perforate 105 are set to semicircle on described, a big groove 102 is vertically installed with along contact pedestal 1 top and the bottom at described tapping, two little grooves 101 are provided with in two sides of big groove 102, moving contact 401 on one is provided with on described in perforate 103, a lower moving contact 402 is provided with in described lower perforate 105, the contact anchor ear 3 of an oval type is had in the arranged outside of described two moving contacts, be close to identical on the lower edge of described contact anchor ear 3 and the lower edge of lower moving contact 402, two described little grooves 101 are close in two sides of contact anchor ear 3, a helical spring 2 is arranged with in opening joining place on contact anchor ear 3 top, edge on the middle part that described helical spring 2 is pressed on moving contact 401, big groove 102 limit of described contact pedestal is close in the outside of helical spring 2.
Further setting, described moving contact 4 is cylinder, two ends of moving contact 4 extend to the outside of contact pedestal 1, described moving contact 4 two end cylinder is larger, middle part cylinder is less, and the semicircle that the bottom of its middle part cylinder radius and described upper perforate 103 and the top of lower perforate 105 are arranged coincide mutually.
The working procedure of the moving contact group of said structure is as follows: when described moving contact group is applied in isolating switch, when moving contact group and fixed contact are in separated position, isolating switch is in gate-dividing state, load circuit no-voltage, isolation maintenance can be carried out to loaded line, when pushing moving contact group to fixed contact under the effect of isolating switch in external force and engaging each other, isolating switch is in "on" position, can power to load circuit; When moving contact group is applied to duplicate supply, described stationary contact head group is two groups, the two-way power supply power supply of composition end of incoming cables, described moving contact group is one group, form the leading-out terminal of duplicate supply, when engaging with first group of stationary contact head group under the effect of moving contact group in external force, load circuit be first group of power supply, when engaging with the second stationary contact head group under the effect of moving contact group in external force, load circuit just switches to second group of power supply.
