Abstract
The utility model relates to a contact structure for converting switch of power supply, which is used for the duplicate supply converting switch and belongs to the technical field of the low-voltage electrical apparatus components. The contact structure for converting switch of power supply mainly comprises that the static contacts are symmetrically arranged on the insulating shell. A loading copper row is arranged on the insulating shell. An insulating part is arranged in the insulating shell. A movable contact is fixed in the insulating part. A pressure spring is arranged in the insulating part. The pressure spring is contacted with the movable contact. The utility model has simple, compact and reasonable structure, small volume and low cost of manufacture. Because the contact structure for converting switch of power supply makes two static contacts be symmetrically arranged on the insulating shell, the distance between the static contact and the movable contact is long, which is not easy to cause discharge and short circuit. The contact structure for converting switch of power supply is convenient to arrange and use and has stable and reliable performance.
Description
Technical field
The utility model relates to a kind of transfer switch appliance contact structure, is used for dual-power transfer switch, belongs to low-voltage electrical apparatus components and parts technical field.
Background technology
Before the utility model was made, in prior art, the appliance contact that is used for dual-power transfer switch mainly adopted two fixed contacts to be installed in insulation shell side by side, at a distance of too short, easily caused discharge short between fixed contact and the moving contact; And overall volume is big, the manufacturing cost height.
Technology contents
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Volume is little, low cost of manufacture; Easy to install, be difficult for causing discharge short, transfer switch appliance contact structure stable and reliable for performance.
Main solution of the present utility model is achieved in that
The utility model mainly adopts fixed contact 2,7 symmetries to be installed on the insulation shell 1, load copper bar 9 is installed on the insulation shell 1, and insulating part 3 is installed in the insulation shell 1, and moving contact 5 is fixed in the insulating part 3, setting pressure spring 8 in insulating part 3, compression spring 8 contacts with moving contact 5.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Volume is little, low cost of manufacture; Owing to adopt two fixed contact symmetries to be installed on the insulation shell, at a distance of longer, be difficult for causing discharge short between fixed contact and the moving contact; Easy to install, stable and reliable for performance.
Description of drawings
Fig. 1 is the utility model structural front view.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of insulation shell 1, fixed contact 2,7, insulating part 3, silver strip 4,6, moving contact 5, compression spring 8, load copper bar 9, flexible link 10 etc.Adopt fixed contact 2,7 symmetries to be installed on the insulation shell 1, on fixed contact 2,7, weld silver strip 6 respectively.Installation load copper bar 9 on insulation shell 1, insulating part 3 are installed in the insulation shell 1, and moving contact 5 is fixed in the insulating part 3, welding silver strip 4 on moving contact 5, and moving contact 5 is shaped as L shaped.Setting pressure spring 8 in insulating part 3, compression spring 8 contacts with moving contact 5, gives moving contact 5 certain pressures by compression spring 8, when insulating part 3 rotates, silver strip 4 is closely contacted with silver strip 6, play the energising effect, offer load by load copper bar 9, flexible link 10.Load copper bar 9 is installed on the insulation shell 1, and load copper bar 9 connects moving contact 5 by flexible link 10.
