Technical field
The utility model belongs to the technical field of electronics, relates to a kind of isolating switch, specifically, is a kind of isolating switch of multiple-grooved.
Background technology
Isolating switch is a kind of more common electronic devices and components, is widely used in production and the life.Isolating switch is claimed knife switch or isolating switch again, and it is a most simple and practical a kind of low-voltage electrical apparatus.Isolating switch generally comprises: compositions such as (insulation) base, blade, tool rest and Bakelite Cover.
Isolating switch is used as the switch of insulating power supply usually, so that can overhaul or change fuse safely to electric equipment.Isolating switch also can be used as the mains switch of line-start motor.When selecting plug-in strip for use, three times of the about Daewoo of the rated current of isolating switch motor rated current.According to the blade number what, isolating switch divides one pole (hilted broadsword), bipolar (double-pole), three utmost points (three cuttves).
Existing commercially available isolating switch generally includes: base (ceramic wafer), handle, contact knife, contact knife support, inlet wire connector assembly, outlet connector assembly, and protective cover.Inlet wire connector assembly, outlet connector assembly are separately fixed at the two ends of ceramic wafer; The contact knife support is fixed on the base middle part, and contact knife is hinged on the contact knife frame for one section, and the contact knife frame bottom is fixed on the ceramic wafer middle part; Contact knife one end is hinged on the contact knife support, and the contact knife frame bottom is through the screw lug plate.The outlet connector assembly comprises: on lug plate and the lug plate, the cross section is the lead fastening frame that the degree of lip-rounding is provided with housing pin.The inlet wire connector assembly comprises: the contact that lead fastening frame, brace and cross section are triangular in shape substantially and step up at the top.This isolating switch complex structure, manufacturing cost height, plug-in strip is whole heavy and frangible, and heating is big, easy initiating failure, influence is produced.Usually base has a big groove, and when contact knife closed a floodgate, big groove had the danger of electric shock.
The utility model content
The purpose of the utility model is, a kind of isolating switch of multiple-grooved is provided, to overcome the above-mentioned shortcoming and defect of existing in prior technology.
The technical problem of the required solution of the utility model, can realize through following technical scheme:
The isolating switch of multiple-grooved comprises base plate, handle, contact knife, contact knife support, inlet wire connector assembly, outlet connector assembly and protective cover, and the outlet connector assembly comprises: lug plate and be enclosed within the lead fastening frame on the lug plate; The inlet wire connector assembly comprises another lead fastening frame, brace and contact, and said contact knife support and lug plate are structure as a whole, and by T font copper sheet both wings is rolled in the same way mutually to form the contact knife support, and the centre of T font copper sheet vertically part constitutes lug plate; Said contact and brace are similarly integrative-structure, and also the centre by T font copper sheet vertically partly constitutes brace, and the opening part of said contact respectively is provided with bow strip on inboard two relative planes; Bow strip protrudes against each other; Said bow strip tilts to the contact knife holder orientation, and is parallel with the contact knife of closing moment, it is characterized in that; Said base plate is provided with the groove that holds contact knife, and the quantity of said groove and the quantity of contact knife are complementary.
Wherein a kind of embodiment, the quantity of said contact knife is 2, the quantity of said groove is 2.
Wherein another kind of embodiment, the quantity of said contact knife is 3, the quantity of said groove is 3.
The beneficial effect of the utility model:
The utility model base plate 1 is provided with the groove that holds contact knife 3, and the quantity of the quantity of said groove and contact knife 3 is complementary.Increased the fail safe of using.
Because 11 pairs of contact knifes of groove play spacing effect, have increased the accuracy that contact knife is opened a sluice gate and closed a floodgate.
