Description

Electromagnetic relay

Technical field

The present invention relates to a kind of electromagnetic relay, particularly relate to a kind of industrial and controlling signal transmission electromagnetic relay.

Background technology

Consult Fig. 1, Fig. 2; The electromagnetic relay 1 that discloses No. 200802473 case of case with the previous tw Taiwan of applying for of this case applicant in early days is an example; The shell block 12, a touch-control group 13, the switches set 14 that mainly comprise an electromagnetic unit 11, this electromagnetic unit 11 of bearing, and a shell 15 of encapsulation aforementioned electromagnetic unit 11, shell block 12, touch-control group 13, switches set 14.This electromagnetic unit 11 has the carrier 112 that twines a coil 111, be blocked in these coil 111 2 adjacent edge sides a locating part 113, pass this coil 111 and be connected in series this locating part 113 one unshakable in one's determination 114, be attached at this carrier 112 microscope carrier 115 of end on one side, and run through this microscope carrier 115 and connect two pins 116 of this coil 111.This touch-control group 13 has riveting and is located at the shell fragment 131 of these locating part 113 1 sides, movable a magnetic conductive component 132 that is arranged on 112 in this shell fragment 131 and this carrier, and forms a Passive part 133 of interlocks with this magnetic conductive component 132.This switches set 14 has a first terminal 141 and one second terminal 142 that is installed in this shell block 12, and is set in this 141,142 of first, second terminal and forms one the 3rd terminal 143 of interlocks with this Passive part 133.

When no power during in aforementioned pin 116, this magnetic conductive component 132 is the elastic force effects that receive this shell fragment 131, and this Passive part 133 tractions the 3rd terminal 143 of interlock is to contacting with this first terminal 141; When switching in aforementioned pin 116; This electromagnetic unit 11 can produce electric field, attracts this this Passive part 133 of magnetic conductive component 132 interlocks, and the elastic force that makes this Passive part 133 drives the 3rd terminal 143 overcome this shell fragment 131 extremely contacts with this second terminal 142; Whereby, reach the on-off action of ON/OFF.

But; Because this microscope carrier 115 only links with limit end and this carrier 112; The not only not enough fracture easily of structural strength, and the shell fragment 131 of riveted joint, do not receive spacing and magnetic conductive component 132 that drop easily, all can increase the complicated property and the degree of difficulty of assembling procedure; And be not easy to replace manual operation with automated job, have that output can't promote, the more high disappearance of cost.

In addition, for this electromagnetic unit 11 of bearing, this shell block 12 is adopted open by design, and not only insulation effect is not good, and the precision can reduce each inter-module assembling the time, and withstand voltage properties can't effectively be promoted.So this case inventor as satisfying, is not still adhering to excelsior spirit, constantly detailed think of funiculus and the skilful intelligence of utilization are are actively researched and developed with great concentration, eventually appearance of the present invention must be arranged.
