Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail:
As shown in Figures 1 to 4, electromagnetic relay 100, comprises housing 110.Housing 110 is provided with cavity volume 111.In cavity volume 111, be provided with circuit switching device and electromagnetic control assembly.Circuit switching device is used for being switched on or switched off controlled circuit.Circuit switching device comprises that one end is arranged in cavity volume 111, and static terminal 121 and moved end 122 outside cavity volume 111 stretched out in one end.The static terminal 121 stretching out outside cavity volume 111 is connected to controlled circuit with moved end 122.Static terminal 121 and moved end 122 be cavity volume 111 is interior while being electrically connected to, controlled circuit electric connection.Static terminal 121 is with moved end 122 when the interior disconnection of cavity volume 111, and controlled circuit electricity disconnects.
In an example of the present utility model, circuit switching device comprises static terminal 121, moved end son 122 and movable contact spring 123.Static terminal 121 and moved end 122 are installed on housing 110.Static terminal 121 and moved end 122 are one end and are arranged in cavity volume 111; The other end stretches out outside cavity volume 111.Movable contact spring 123 is arranged in cavity volume 111.Movable contact spring 123 one end are electrically connected to moved end 122, and the other end is provided with moving contact 124.On static terminal 121, be provided with fixed contact 125.Fixed contact 125 relatively arranges with moving contact 124 positions.One end that movable contact spring 123 arranges moving contact 124 arranges movably.Movable contact spring 123 moves and can make moving contact 124 and fixed contact 125 electrically contact, thereby makes static terminal 121 logical with son 122 Electricity Federations, moved end by fixed contact 125 and moving contact 124.
In cavity volume 111, be also provided with electromagnetic control assembly.Electromagnetic control assembly moves for the one end that drives movable contact spring 123 that moving contact 124 is set, thereby moving contact 124 is contacted with fixed contact 125.Electromagnetic control assembly comprises coil 131, iron core 132, armature 133, yoke 134 and coil brace 135.Coil brace 135 comprises coil axes 1351 and is arranged at the support arm 1352 at coil axes 1351 two ends.Two support arms 1352 protrude from coil axes 1351.Coil 131 is wrapped on coil axes 1351.Iron core 132, through coil axes 1351, makes coil 131 arrange around iron core 132.Iron core 132 one end are connected with yoke 134.Yoke 134 is L-type.Yoke 134 one end 1341 are connected with iron core 132.Yoke 134 parts 1342 and coil axes 1351 are arranged on a side of coil 131 abreast.Armature 133 is L-type.Armature one end 1332 arranges near iron core 132 ends, and the armature other end 1333 is arranged on coil axes 1351 side that is positioned at coil 131 abreast, and with yoke 134 homonymies.Armature middle part 1331 is overlapped on a support arm 1352 of coil axes 1351, and arranges rotationally.Armature one end 1332 can be subject to iron core 132 attract or repel, thereby armature 133 is rotated.When armature 133 rotates, the armature other end 1333 near or away from yoke 134.When the armature other end 1333 is during away from yoke 134, the armature other end 1333 contacts with movable contact spring 123, and and then to make it the fixed contact 125 that arranges on static terminal 121 close, until complete moving contact 124, be electrically connected to fixed contact 125.In embodiment as shown in Figure 3, Figure 4, static terminal 121, movable contact spring 123 and yoke 134 set gradually from top to bottom.Movable contact spring 123 is parallel with yoke 134.Coil 131 can be connected with coil power by two coil terminals 137.
Electromagnetic control assembly also comprises the fixture 136 being fixed in yoke 134, for supplemental support armature 133, and limits its range of movement.Fixture 136 can be fixed in yoke 134 by variety of way, and realizes fixture 136 simultaneously and be electrically connected to yoke 134.For example, fixture 136 comprises that a junction divides 1361, is connected with the perforate 1343 in yoke 134, and fixture 136 is fixed in yoke 134.Fixture 136 also comprises a support section 1362, for armature 133 is connected movably with yoke 134.In preferred embodiment as shown in Figure 2, fixture support section 1362 comprises the elastic arm of a pair of space.After electromagnetic relay assembling in the utility model, elastic arm 1362 is overlapped on the projection 1335 arranging on armature 133, the armature other end 1333 is remained on to the position contacting with yoke 134.
In embodiment as shown in Figure 3, Figure 4, before coil 131 is not switched on, movable contact spring 123 is in normal condition, and moving contact 124 is mutual to arranging with yoke 134.In this position, moving contact 124 separates with fixed contact 125, does not contact, and controlled circuit is in off-state.
When coil 131 energising, iron core 132 produces magnetic.Iron core 132 attracts armature 133, makes its rotation.With reference to shown in Fig. 2 to Fig. 4, when being subject to iron core 132, armature one end 1332 attracts after iron core 132 motions, and armature 133 rotates under the support of support arm 1352, for example, along the counter clockwise direction in figure, rotates (shown in Fig. 3).The rotation of armature 133 and then overcome the confining force of elastic arm 1362 on fixture with the moving armature other end 1333, deviates from yoke 134 and moves, and for example, along upward direction in figure, rotates.When the armature other end 1333 is so mobile, can drives movable contact spring 123 to depart from its normal condition and move (for example upward direction moves in the drawings) towards fixed contact 125.Movable contact spring 123 produces elastic deformation force thus.After movable contact spring 123 moves up, moving contact 124 is contacted with fixed contact 125, connect controlled circuit.
After coil 131 power-off, iron core 132 loses magnetism, and the attraction of armature 133 is disappeared.Under the effect of the armature other end 1333 elastic arm 1362 confining forces on fixture, towards yoke 134, move, disengage with movable contact spring 123 gradually.Movable contact spring 123 is homing under elastic reaction, makes moving contact 124 separated with fixed contact 125.
By to coil 131 energising and power-off, can realize moving contact 124 and contact with separated with fixed contact 125, thereby controlled circuit is switched on or switched off.
Electromagnetic relay of the present utility model also comprises conducting connecting part 138, and conducting connecting part 138 is electrically connected to described yoke 134 and movable contact spring 123.Conducting connecting part 138 both can arrange one, also can arrange a plurality of.And conducting connecting part 138 can be tabular, sheet, wire, strip or bar-shaped.Conducting connecting part 138 both can contact with fixture 136, also can contact with yoke 134, can also contact with yoke 134 and fixture 136 simultaneously.In preferred embodiment as shown in Figure 4, Figure 5, conducting connecting part 138 is tabular, and two ends contact with movable contact spring 123 and yoke 134 respectively, and both are electrically connected to.And conducting connecting part 138 is positioned at movable contact spring 123 and yoke 134 the same sides, convenient installation.
The upper and lower relative concept that is in the utility model.
Electromagnetic relay in the utility model, utilizes conducting connecting part that movable contact spring and yoke are electrically connected to, and makes both electromotive forces remain equal, can be because not existing electrical potential difference to produce electric spark or noise.The utility model has been eliminated because of the caused drawback of electromagnetic relay miniaturization and problem.
Embodiment in the utility model, only for the utility model is described, does not form the restriction to claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in the utility model protection range.
