The utility model discloses simple structure, overall dimension are little, when rotate the movable contact spring with last in, first power circular telegram during the contact of left static contact down, when rotate movable contact spring and a left side down, the second source is switched on during right quiet male contact down.
Description
Technical field
This utility model relates to a kind of twin-power switch.
Background technology
The effect of twin-power switch is: when a road power failure (have a power failure, under-voltage, overvoltage, disconnected phase, frequency shift (FS)), twin-power switch makes to automatically switch between power supply, to ensure reliability and the safety of power supply, it is widely used in the important place that skyscraper, community, hospital, airport, harbour, fire-fighting, metallurgy, chemical industry, weaving etc. do not allow to have a power failure, realize unmanned to power continuously, cause the damage of power equipment in order to prevent two-way power supply to be also turned on. At present, twin-power switch generally comprises four terminals on housing and housing, and each two terminals connect a power supply, and each power supply is equipped with a switch lock, drives switch lock again through other linkage structures, and said structure volume is relatively big and structure is complicated.
Summary of the invention
In view of the deficiency of background technology, the twin-power switch that technical problem to be solved in the utility model is to provide a kind of simple in construction, overall dimensions is little.
For this, this utility model adopts following scheme to realize:
A kind of twin-power switch, including housing, it is characterized in that: described housing extenal fixation is provided with three binding posts, three binding posts electrically connect with three static contacts being located in housing respectively, three static contacts are upper, bottom left and bottom right position are laid, the central authorities of three static contacts are provided with movable contact spring, movable contact spring rotates to arrange and is driven by individual motor, described movable contact spring has three sheet feet, in Y-shaped between three sheet feet, the top of three sheet feet is provided with three movable contacts, movable contact spring is before rotation, two movable contacts of movable contact spring are with upper, the static contact contact of bottom left, movable contact spring is after rotation, two movable contacts of movable contact spring and bottom left, the static contact contact of bottom right.
Described movable contact spring is stamping parts, and the centre of movable contact spring is stamped and formed out square groove, and through square rotating shaft in square groove, the axle head of square rotating shaft is connected with described motor.
Binding post and static contact are integrated stamping parts structure.
After adopting technique scheme, binding post only has three, reduce the overall dimensions of twin-power switch, drive motor can drive movable contact spring and corresponding movable contact to rotate, the first power supply energising when rotating movable contact spring and contacting with upper, bottom left static contact, second source energising, simple in construction when rotating movable contact spring and contacting with bottom left, bottom right static contact.
Accompanying drawing explanation
This utility model has drawings described below:
Fig. 1 is this utility model structural representation when connecting the first power supply;
Fig. 2 is structural representation during this utility model connection second source.
Detailed description of the invention
As depicted in figs. 1 and 2, twin-power switch of the present utility model, including housing 1, described housing 1 extenal fixation is provided with three binding post a, b and c, three binding post a, b, the static contact a1 that c is located in housing 1 with three respectively, b1, c1 electrically connects, binding post and static contact are integrated stamping parts structure, three static contact a1, b1, c1 is upper, bottom left and bottom right position are laid, the central authorities of three static contacts are provided with movable contact spring 2, movable contact spring 2 rotates to arrange and is driven by individual motor, described movable contact spring 2 is stamping parts, the centre of movable contact spring 2 is stamped and formed out square groove, through square rotating shaft 3 in square groove, the axle head of square rotating shaft 3 is connected with described motor. described movable contact spring 2 has three sheet feet, in Y-shaped between three sheet feet, the top of three sheet feet is provided with three movable contact a2, b2 and c2, movable contact spring 2 is (Fig. 1 is shown) before rotation, two movable contacts a2, b2 of movable contact spring contact with static contact a1, b1 upper, bottom left, movable contact spring is after rotation (shown in Fig. 2), and two movable contacts c2, a2 of movable contact spring contact with static contact b1, c1 of bottom left, bottom right.
Utility model works principle is as follows: drive motor can drive movable contact spring 2 and movable contact a2, b2, c2 to rotate by square rotating shaft 3, movable contact spring is (Fig. 1 is shown) before rotation, two movable contacts a2, b2 of movable contact spring contact with static contact a1, b1 upper, bottom left, first power supply energising, movable contact spring is (Fig. 2 is shown) after rotation, two movable contacts c2, a2 of movable contact spring contact with static contact b1, c1 of bottom left, bottom right, and second source is energized.
