Description
Technical Field
The utility model relates to an electrical equipment, concretely relates to relay.
Background
The relay is mainly applied to a control circuit, and is actually an 'automatic switch' which uses small current to control large current operation. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. One of the relays can be used for switching on and off a two-way circuit, but the internal structure of the relay on the market is often more complex, so that the size of the relay is larger, and the production and assembly are more troublesome.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design can realize the automatic relay of on-off control of two way circuits.
Therefore, the utility model discloses an adopt following scheme to realize:
double-circuit control formula relay has the shell body, its characterized in that: the shell body is provided with a first fixed contact, a second fixed contact and an electric connector which penetrate out of the shell body, the electric connector is electrically connected with an electromagnetic coil arranged inside the shell body, the electromagnetic coil is coated with an iron core, a swinging seat is arranged inside the shell body, one end of the swinging seat is connected with an elastic piece, an adsorption piece matched with the iron core is arranged on the swinging seat, and a moving contact which can be contacted with the first fixed contact or the second fixed contact is connected onto the swinging seat.
The elastic piece is a spring.
The swing seat and the adsorption piece are of an integrated structure.
And magnetic parts are arranged at positions close to the first fixed contact and the second fixed contact.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: simple structure, reasonable in design, the production equipment of relay of being convenient for, and whole size also can set for comparatively little, when the electricity connects not circular telegram, the swing seat swings to one side under the pulling of elastic component for the moving contact contacts with one of them static contact, realize the switch-on of this way circuit, the disconnection of another circuit, when the electricity connects the circular telegram, the iron core produces magnetism under solenoid's effect, and attract swing seat swing to the opposite side, make the moving contact with another static contact, realize the switch-on of this way circuit, the disconnection of another circuit.
Drawings
The utility model discloses there is following figure:
FIG. 1 is an external structural view of the present invention;
FIG. 2 is an internal structural view of the present invention;
fig. 3 is a structural view of fig. 2 with an upper fixing plate removed.
Detailed Description
As shown in the figure, the utility model discloses a double-circuit control formula relay has shell body 1, be provided with the first static contact 2 of wearing out shell body 1 on shell body 1, second static contact 3 and electric joint 4, it is first, the second static contact is fixed on fixed plate 10, electric joint 4 is connected with the solenoid 8 electricity that sets up in shell body 1 inside, solenoid 8 cladding has iron core 5, be provided with swing seat 6 in shell body 1's inside, be provided with mounting bracket 11 in shell body 1's inside, swing seat 6 can swing and connect on mounting bracket 11, swing seat 6's one end is connected with elastic component 7, in this embodiment, elastic component 7 is the spring. The swing seat 6 is provided with an adsorption piece matched with the iron core 5, the adsorption piece can be made of iron materials, the adsorption piece can be independently connected to the swing seat 6, and the swing seat 6 can also be in an integrated structure with the adsorption piece. The swing seat 6 is connected with a movable contact 9 which can be contacted with the first fixed contact 2 or the second fixed contact 3. A magnetic part 12 is disposed near the first stationary contact 2 and the second stationary contact 3, in this embodiment, the magnetic part 12 is magnetic steel and is disposed on the fixing plate 10. When the moving contact 9 is disconnected with a fixed contact, a large arc may be generated between the contacts, so that the contacts are ablated, the service life of the relay is reduced, and even a short circuit occurs.
The utility model discloses a relay, a structure is simple, and reasonable design, the production equipment of the relay of being convenient for, and whole size also can set up the less, when the electricity is not switched on to the electricity connector 4, swing seat 6 swings to the left side under the pulling of elastic component 7, make moving contact 9 and the contact of first static contact 2, realize the switch-on of this way circuit, the disconnection of another circuit, when the electricity is connected to the electricity connector 4, iron core 5 produces magnetism under solenoid 8's effect, and attract swing seat 6 to swing to the opposite side, and extrude the spring, make moving contact 9 and the contact of second static contact 3, realize the switch-on of this way circuit, the disconnection of another circuit. The first fixed contact is a normally closed end, and the second fixed contact is a normally open end. When the first static contact 2, namely the normally closed end, is connected with the moving contact 9, the first static contact 2 is connected with the moving contact 9 at the moment and can be used by a load; when the first fixed contact 2, i.e. the normally closed end, is not connected to the movable contact 9, the first fixed contact 2 and the movable contact 9 are not connected, so that the load is not switched on,but do notThe signal indicating device is connected to the first static contact to output a voltage or current signal in a certain proportion, and the signal indicating device can monitor the operation state of the load working at the normally open end, namely the second static contact 3.
