Abstract
The utility model discloses a cellular type low pressure switch switches of working a telephone switchboard more, including the switch, the both ends of switch be the moving contact, the moving contact mutually support with the static contact and be connected, the static contact install at insulator its characterized in that: the static contact on be provided with a plurality of wiring mounting holes, the wiring mounting hole in respectively the cooperation have the wiring clamp plate of bolt fastening, compare with prior art, the utility model has the advantages of electric conductive property is good, and stability is high.
Description
Technical field
The utility model relates to low voltage switch technical field, particularly a kind of many wiring cellular type low-voltage knife switch.
Background technology
At present, fixed contact on low-voltage knife switch on market is single wiring hole, its wiring string holes is provided with the wiring pressing plate that bolt is fixing, because the contact area of wiring pressing plate and wire is less, there is the shortcoming of loose contact, poor electric conductivity, the wiring fixed form of this structure also easily causes wire dropping in addition, thus causes electrical network open circuit, there is larger potential safety hazard.
Utility model content
For above-mentioned defect, the technical problem that the utility model mainly solves is to provide a kind of two wiring cellular type low-voltage knife switch.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of many wiring cellular type low-voltage knife switch, comprise disconnecting link, the two ends of described disconnecting link are moving contacts, described moving contact cooperatively interacts with fixed contact and is connected, described fixed contact is installed on insulator, it is characterized in that: described fixed contact is provided with multiple wiring installing hole, is combined with the wiring pressing plate that bolt is fixing in described wiring installing hole respectively.
In another preferably technical scheme, the quantity of described wiring installing hole is two.
The beneficial effects of the utility model are: many wiring cellular type low-voltage knife switch of this spline structure has and conducts electricity very well, the advantage that stability is high.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, disconnecting link 2, moving contact 3, fixed contact 4, insulator 5 wiring installing hole 6, bolt 7, wiring pressing plate.
Embodiment
Below in conjunction with accompanying drawing to embodiment further instruction.
As shown in Figure 1, the utility model many wiring cellular type low-voltage knife switch, comprise disconnecting link 1, the two ends of described disconnecting link 1 are moving contacts 2, described moving contact 2 cooperatively interacts with fixed contact 3 and is connected, described fixed contact 3 is arranged on insulator 4, it is characterized in that: described fixed contact 3 is provided with multiple wiring installing hole 5, is combined with the wiring pressing plate 7 that bolt 6 is fixing in described wiring installing hole 5 respectively.
In another preferred embodiment, the quantity of described wiring installing hole 5 is two.
The utility model has and conducts electricity very well, the advantage that stability is high.
