Please refer to the drawing 1 is to Fig. 4, and in the present embodiment, contactor 100 is three-phase contactor, and its rated operational current reaches the 400A(peace).Among this embodiment, inductance coil 131 drives in the horizontal direction linear reciprocating motion of magnetic pole core 123, and magnetic pole core 123 drives drive links 122 and swings, drive link 122 drive central shafts 121 in predetermined angular clockwise or rotate counterclockwise.
Detailed, electrically-controlled component 130 also comprises the first fixed head 132 and the second fixed head 133 that is oppositely arranged with the first fixed head 132.Inductance coil 131 is located between the first fixed head 132 and the second fixed head 133, and magnetic pole core 123 wears the second fixed head 132 and is inserted in the inductance coil 131.
One end of magnetic pole core 123 is concaved with cave section 1231, and an end of drive link 122 is provided with the joint portion 1221 in the 1231 interior activities of cave section, and the other end of drive link 122 is immobilizated in central shaft 121.
Be provided with tooth section 1211 on the central shaft 121, tooth section 1211 is provided with central shaft 121 and rotates the flank of tooth 1212 that floats.Unit phase 110 also comprises the spring housing 117 that is provided with tooth section 1171.The tooth section 1211 of central shaft 121 and tooth section 1171 match and merge driving spring chamber 117 and float, and spring housing 117 is connected with moving conductive rod 115 and to drive moving conductive rod 115 unsteady.Moving conductive rod 115 come-up can with static conductive rod 113 adhesives.
Counter-force elastic component 116 is reaction spring, and an end of reaction spring is held in insulation shell 111, and spring housing 117 is extended with the other end that supports reaction spring and the hook part 1172 that can compress reaction spring and reset when reaction spring rebounds.
The unit mutually 110 also comprises the wire 118 that connects moving conductive rod 115 and negative pole 114, and the vacuum conduction chamber 119 of contact environment being provided for static conductive rod 113 and moving conductive rod 115.
When the unit 110 is provided with when a plurality of mutually, such as three among the above-mentioned embodiment, central shaft 121 runs through unit mutually 110.Mechanical driving device 120 arranges drive link 122 and magnetic pole core 123 between 110 mutually in per two unit.Electrically-controlled component 130 corresponding each magnetic pole core 123 are respectively arranged with inductance coil 131.Can guarantee that so unit 110 is driven mutually simultaneously, can guarantee again to have enough power and stability.
Please refer to the drawing 5 is to Fig. 8, and contactor 100 specific works principles are as follows: when initial, contactor 100 units mutually 110 positive pole 112 all are in off-state with negative pole 114.During work, inductance coil 131 energisings produce magnetic field, adhesive magnetic pole core 123, and magnetic pole core 123 is toward inductance coil 131 interior movements and drive drive link 122 swings; The swing of drive link 122 and then driving central shaft 121 along clockwise direction (page with Fig. 5 is seen) rotate, tooth section 1211 was raised to the adhesive height along with rotation causes the flank of tooth 1212 from elemental height after central shaft 121 rotated, be that in the vertical direction is raised certain altitude, tooth section 1211 matches with the tooth section 1171 of spring housing 117, flank of tooth driving spring chambers 117 1212 move upward, thereby moving conductive rod 115 is moved upward, and finally contact with static conductive rod 113, thereby positive pole 112 and negative pole 114 are connected.Because central shaft 121 is arranged in unit phase 110 and matches with the spring housing 117 of unit phase 110 respectively, so when central shaft 121 rotates, can lift simultaneously each spring housing 117,110 positive pole 112 and negative pole 114 are connected simultaneously mutually to make unit.
When inductance coil 131 outage, magnetic pole core 123 is without magnetic fields power, magnetic pole core 123 is without the adhesive of magnetic fields power, make central shaft 121 without the driving effect of drive link 113, the active force of 1212 pairs of spring housing 117 of the flank of tooth disappears, and reaction spring begins bounce-back without the active force compression and spring housing 117 is descended.The decline of spring housing 117 reacts on the flank of tooth 1212 forces central shaft 121 oppositely namely counterclockwise to rotate, and makes drive link 122 backswings and magnetic pole core 123 is extracted return to initial condition from inductance coil 131.Drive moving conductive rod 115 after spring housing 117 descends and descend, thereby moving conductive rod 115 and static conductive rod 113 are separated, positive pole 112 and negative pole 114 are disconnected.
The insulation shell 111 of unit phase 110 is absolute independent, and drives simultaneously by central shaft 121, and in theory, central shaft 121 can infinitely prolong, and unit mutually 110 quantity can infinitely increase, and conveniently carries out maintenance and the replacing of any unit phase 110; Simultaneously, can increase by the parallel connection of a plurality of unit phase 110 operating current of contactor 100.As shown in Figure 9, contactor 200 is three-phase contactor, whenever 110 is formed in parallel mutually by two unit, so that the rated current of this three-phase contactor reaches 800A.Equally, can be set to mutually three unit and be in parallel so that the rated current of three-phase contactor reaches 1200A by every.Even, make rated current reach higher by being arranged in parallel.By central shaft 121 simply being set, increasing or reducing unit phase 110, can form the contactor of various rated current again, the shell that has solved traditional contactor is the problem that integral type can't simply increase the repair and replacement of rated current meter.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
