By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Fig. 1 depicts the viewgraph of cross-section of the relay according to a kind of execution mode.As shown in Figure 1, the utility model provides a kind of relay with the antifreeze contact of low temperature, comprising: solenoid, its electric current by time generate heat; First contact, and between described coil, there is cavity; Second contact, and between described coil, there is cavity; And Heat Conduction Material, it is arranged in described cavity, and at least one connection in described solenoid and described first contact and described second contact, with by heat from condensation at least one described at least one and anti-sealing described in described coil is delivered to described first contact and described second contact are in described first contact and described second contact; Swing arm, it is positioned at the top of solenoid, and for touching the first contact and the second contact; Output pin A, it connects the side of solenoid; Output pin B, it connects the opposite side of solenoid; Output pin C, it connects described swing arm and is positioned at homonymy with described output pin A; Output pin D, it connects the first contact and is positioned at homonymy with described output pin B.
Further, relay also comprise shell with receive described coil, described first contact at least partially, described first contact and described Heat Conduction Material.
Further, described Heat Conduction Material directly contacts described coil.
Further, described Heat Conduction Material directly contacts described first contact so that heat is delivered to described first contact from described coil.
Further, described Heat Conduction Material comprises based on the one in the material of grease and polymer, and this polymer comprises a kind of filler in pottery and graphite granule.
Relay generally includes shell, coil, armature and the first contact and the second contact.Relay also comprises the first contact, the first contact and armature and flex contact integral, and the first contact is connected to the first contact.First contact is given prominence to from the downside of shell.Relay also comprises the second contact, when hope activate coil and cause the first contact, the second contact contact with each other time, this second contact is electrically coupled to coil to provide electric current.Multiple second contact is also given prominence to from shell.Relay also comprises normally closed contact contact, and it is connected to flex contact.When cut-off (or stopping using), this normally closed contact contact first contact.When relay is activated, the first contact is moved to contact the second contact away from normally-closed contact and is flowed from relay to make electric current.Opening is in-between defined in coil and the 3rd contact.First Heat Conduction Material (such as, heat pad) is positioned at opening to contact a part for the comprised contact of coil and the 3rd contact to transfer heat to the second contact.First supporting member can be positioned at shell or integral with at least side supporting or engage the first Heat Conduction Material with shell.Should be familiar with, opening can present any amount of geomery to be conducive to receiving and to support the first Heat Conduction Material.First Heat Conduction Material also can comprise heat conducting foam, and it improves the contact between the electric parts of heating and radiator.
Normally, the first Heat Conduction Material can with coil and contact thermal communication to be delivered to contact by heat from coil.In one example, the first Heat Conduction Material directly can contact with coil.The maximum part of coil itself normally in relay and it comprises copper.Once coil is excited (or activation), then coil heating.In this case, coil serves as hot memory element, because coil provides with the thermal inertia larger than the miscellaneous part in relay.Such as, coil stores the longer time quantum of heat than the miscellaneous part in relay.In addition, coil needs the more time to cool than the miscellaneous part in relay.On the contrary, each in contact usually has little metal quality and therefore cools sooner.
The relay employing the first Heat Conduction Material can make the temperature between contact and coil equal.Such as, heat is delivered to contact from coil and causes the temperature of contact to increase, and when relay is stopped using, this provides the slower cooling cycle to contact.Relay one is stopped using, and this situation just anti-sealing moves to contact.In this case, water will move to other regions in shell, once relay is stopped using, then these other regions in shell can present the temperature colder than contact.Finally, when all heat from coil fully transmit and by the first Heat Conduction Material 348 time, the temperature of contact will reduce.But in this case, water has moved to other parts of relay and water will not be frozen on contact.
