Abstract
The utility model discloses a normally open relay which comprises a static contact a moving contact which are correspondingly arranged. The static contact is connected to a static conductive plate. The moving contact is connected to one end of a moving conductive plate. The other end of the moving conductive plate is hinged to a first bracket. The relay is also provided with a connection rod device to control the up and down movement of the moving conductive plate. The right side of the connection rod device is connected with a tension spring, and the left side of the connection rod device is hinged to an electromagnetic core. An electromagnetic coil sleeves the electromagnetic core. according to the normally open relay, the gap between the static contact the moving contact is increased, thus the safety isolation performance between the static contact the moving contact and the carrying capacity of pressure and current are enhanced, and the normally open relay has the advantages of small size, low cost, large load and broad application space.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the laser soldering device of the utility model relay1 case as Figure 1-3, comprise fixed contact 11, moving contact 10, the setting corresponding to moving contact 10 of described fixed contact 11, described fixed contact 11 is connected on quiet conductive plate 12, described moving contact 10 is connected to one end of moving conductive plate 9, and the other end of described moving conductive plate 9 and the first support 8 are hinged; Relay is also provided with moving up and down of linkage control moving conductive plate 9, and the right of described linkage is connected with extension spring 6, the left side and electromagnetic core 3 chain connections, and described electromagnetic core 3 strings are enclosed within solenoid 2 inside.
Preferably, described linkage comprises connecting rod 4, lower link 7, and described upper connecting rod 4 adopts chain connection with lower link 7, and the other end of described upper connecting rod 4 and the second support 5 are hinged, and the other end of described lower link 7 and moving conductive plate 9 are hinged.The upper end of described lower link 7 is also provided with rectangle projection 701, for limiting the limit rotational angle between upper connecting rod 4 and lower link 7.Described upper connecting rod 4 adopts insulating material to make with lower link 7.
Preferably, described fixed contact 11 adopts dome structures with moving contact 10, adopts dome structure, can realize between fixed contact 11 and moving contact 10 and contacting with a form contacting, and prevents from sticking together between contact.
Preferably, relay is also provided with shell 1, and described solenoid 2 is fixedly connected on its sidewall, and described the first support 8 and the second support 5 are fixedly connected on respectively sidewall and the top in described shell 1, and described extension spring 6 one end are fixedly connected with shell 1 sidewall.
When combined floodgate, electromagnetic core 3 is moved to the left under the effect of solenoid 2, the upper connecting rod 4 of electromagnetic core 3 traction and lower link 7 hinged go out, angle between connecting rod 4 and lower link is constantly increased, until the rectangle projection of lower link 7 upper ends props up the edge of connecting rod 4, meanwhile lower link 7 promotes counterclockwise rotation of moving conductive plate 9, and moving contact 10 is contacted with fixed contact 11, realize the connection of controlled circuit, as shown in 3.
When solenoid 2 power-off, solenoid 2 loses its reliss to electromagnetic core 3, therefore under the pulling force effect of extension spring 6, thereby the articulated position of upper connecting rod 4 and lower link 7 moves right connecting rod 4 and the direct angle of lower link 7 is diminished, lower link 7 drives moving conductive plate 8 to clockwise rotate, moving contact 10 and fixed contact 11 are separated, realize the disconnection of controlled circuit.Should be noted that, under the pulling force effect of extension spring 6, can ensure the safe distance between moving contact 10 and fixed contact 11, even the normal operation that the impact that this relay is subject to the slight vibrations of external environment can interference relay yet.
The beneficial effect the utlity model has: the utility model relay open in usual has increased the gap between dynamic and static contact, thereby safe isolation performance between dynamic and static contact and the bearing capacity of pressure and electric current are strengthened, it has the features such as small size, low cost, heavy load, has and comparatively closes wealthy utilization space.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
