Embodiment
Below in conjunction with a specific embodiment of the present utility model shown in the drawings, further describe the sealed type electromagnetic relay-set of band non-contact testing switch of the present utility model, also further describe characteristics of the present utility model and advantage.
Electromagnetic relay of the present utility model as shown in Figure 1, 2, the base 2 that case 1 and the pressing mold plastics of being made by the pressing mold plastics are made is assembled together jointly and forms a complete sealed chamber.In the anaerobic treatment facility, by the inner processing that vacuumizes deoxygenation and fill inert gas of 3 pairs of sealed chambers of the pore on the base 2, after making inside and outside air pressure balance, case 1 is filled out the sealing of encapsulating stick with the junction of base 2 and to the pore on the base 23, bring up an economy, safety, anaerobic, dead-tight airtight environment, making the conductive component that is operated in the sealed chamber can not produce a bit electric arc reveals, and conductive component is operated in such environment, can keep desirable contact resistance, can not produce the outer temperature rise of power consumption, eliminate the reactive loss that oxidation causes, thereby improved the electrical endurance of electromagnetic relay greatly.
As shown in Figure 2, the externally actuated parts of manual test switch are made up of hand switch, guiding parts and permanent magnet.Described switch is installed on the guiding parts that fixedly installs on case 1 upper surface, and the movement locus that limits by described guiding parts moves.Described permanent magnet is fixedly mounted in the hand switch, and its position is near the permanent magnet on push rod 8 free ends in the sealed chamber.
As shown in Figure 3, form the manual test switch block by guiding parts rail plate on the case 14 and the console switch 5 that contains permanent magnet 6.Form actuated components by the push rod 8 that contains permanent magnet 7, the movable contact spring 11 that moving contact 14 and collets 10 are housed, the pedestal 13 that contains push rod installing hole 12.When console switch 5 is applied external force, console switch 5 is done the location along the direction of motion in the rail plate on the case 14 and is slided, by the heteropole the suction-combining force between the permanent magnet 7 in permanent magnet in the console switch 56 and the push rod 8, driving push rod is that directional swing is done in the axle center with the push rod installing hole on the pedestal 13 12, contacting of collets 10 in salient point 9 by correct position place, push rod 8 middle part and the movable contact spring 11, the power of swing is passed on the movable contact spring 11, movable contact spring 11 overcomes the counter-force of reset tension spring 15, and then action, make between moving contact and the fixed contact to contact/throw off, thereby realize the on/off of the electric current between moving contact and the fixed contact.
In Fig. 3, the sealing wire pin 16 that also has input energizing quantity on the base 2, in the sealed chamber that case 1 and base 2 are formed, except actuated components is housed, other parts that constitute electromagnetic relay also are housed, comprise: relay electromagnetic mechanism, fixed contact 22, moving contact 14 and the reset tension spring 15 formed by iron core 17, solenoid 18, yoke 19 and armature 20.The movable contact spring row 11 that moving contact 14 wherein is housed is subjected to the double drive of the push rod 8 and the armature 20 of actuated components, and reset tension spring 15 not only provides reset response power for armature, and works in actuated components.
The following describes the operating principle of relay of the present utility model.Under normal condition, energizing quantity is by sealing wire pin 16 input relay solenoids 18, described electromagnetic mechanism produces magnetic field because of the input of energizing quantity, armature 20 overcomes the extension spring counter-force and does closing motion with respect to unshakable in one's determination 17 under the effect of magnetic force, drive movable contact spring row 11 motions in the break-make task operating mechanism simultaneously, movable contact spring row 11 drives moving contact 14 motions and finishes closed task with fixed contact 22.When removing energizing quantity, the magnetic field in the described electromagnetic mechanism disappears because of the removal of energizing quantity, and extension spring 15 drives armature 20 and does disengaging movement with respect to unshakable in one's determination 17, thereby thereby driving reed row 11 motions realizes the disjunction action.
Under test mode, the input and the removal that need not energizing quantity can be finished the break-make task, when manual operation button 5 moves toward measurement direction, because of the heteropole suction between the permanent magnet 7 in permanent magnet in the action button 56 and the push rod 8, drive push rod 8 and do closing motion with respect to unshakable in one's determination 17, push rod 8 overcomes the extension spring counter-force and drives movable contact spring row 11 motions, and movable contact spring row 11 drives moving contact 14 motions and finishes closed task with fixed contact 22.Otherwise, when manual operation button 5 moves toward initial position, because of the heteropole suction between the permanent magnet 7 in permanent magnet in the action button 56 and the push rod 8, drive push rod 8 and do disengaging movement with respect to unshakable in one's determination 17, extension spring 15 makes movable contact spring row 11 drive moving contact 14 and gets back to initial condition, thereby finishes the disjunction task of relay.
Above embodiment only is used to illustrate the technical pattern of the sealed type electromagnetic relay of the band non-contact testing switch that the utility model relates to. and operating principle and function, the utility model are not limited to above embodiment.It will be appreciated that, do not leave scope of the present utility model, can carry out multiple changes and improvements, even equivalent way substitutes.
Sealed against leakage is handled except above-mentioned and is sticked with glue agent and fill out the filling, can also adopt the mode of other types such as deposition.
