ーク１３０に固着している。This carpenter's electromagnetic relay, which is small and can be used to switch on and off a large current (several amperes to several tens of amperes), consists of an iron core 111, an excitation winding 112, and an insulating substrate 120 to which all of these are fixed, as shown in Figure 4. , a yoke 130 that is fixed to this insulating substrate 120 and magnetically couples with the lower end of the iron core 111 to form a magnetic path, and an armature 142 that has one end fixed to this yoke 130 and is attracted to the upper end of the iron core 111 in the center. A movable contact plate 140 made of an elastic conductor is formed so that the movable contact 143 at the other end moves substantially parallel to the axial direction of the iron core 111 according to the adsorption operation of the armature 142, and the excitation winding 112
When energized, the movable contacts 143 of the movable contact plate 140 contact the fixed contacts 161, 171 with a fixed pressing force.
The fixed liquid point plates 1go and 170 are equipped with conductor fixed contact plates 160 and 170 held and fixed to the insulating substrate 120.
The excitation winding 112 is wound around the iron core 111 and the wire ends are fully drawn out to the lead-out terminals 113, approximately at the center of the upper substrate 122 and the lower substrate 121 of the insulating substrate 120. The iron core 111 has a lower end passing through the lower substrate 121 and an upper end passing through the upper substrate 122.
On one side of the lower substrate 121 and the upper substrate 122, which are arranged in parallel with each other, an iron core 111 is placed on the opposite side of the lower substrate 121.
The yoke 130, which is magnetically connected to the
26 has fixed contacts 161 and 171 and a pull-out terminal 162.
, 172 are fixed on the top of the upper substrate 122.
Movable contact 143 arranged between 61 and fixed contact 171
A movable contact plate 140 having a movable contact plate 140 covers the movable contact plate 140 . The armature 142 is magnetically connected to the yoke 130 and is attracted to the iron core 111 when the excitation winding 112 is energized, and the movable contact 143 is moved by this attraction. Movable contact plate 1
The end 141 of 40 that does not have the movable contact "143" is fixed to yoke 130.
一般に大電流の断続においては、接続さｎる電気回路の
構成によシ差異はあるが切断電流により接点でのアーク
等の発生は免ｎず、接点部分が発熱し高温となる。Generally, when a large current is turned on and off, the cutting current inevitably generates arcing or the like at the contact point, and the contact portion generates heat and reaches a high temperature, although this varies depending on the configuration of the electrical circuit to be connected.

定さｎると共にアークが発生し易いという問題点があっ
た。The conventional electromagnetic relay described above uses fixed contact plates 160 and 170 made up of wide conductive plates for large currents, but the size of the fixed contacts 161 and 171 is larger than that of the fixed contact plate 1.
Since it is limited by the plate thickness of 60 mm and 170 mm, there are problems in that the current carrying capacity is limited and arcing is likely to occur.

Although the total depth of 11221 was described as being almost the same as the length of the insertion portions 313 and 323, it is only necessary that the fitting and clamping is sufficient.
There is no limitation to this size. It is sufficient that the uneven portions (not shown) on the inner surface of the insertion groove 221 form at least one pair with the uneven portions (not shown) provided on the insertion portion 313 and 323, and usually both sides of the insertion groove However, there is no problem if the inside of the insertion groove 221 is made into a convex part even if there are concave parts on both the upper and lower surfaces of the insertion parts 313 and 323. The same effect can be obtained even if the concave portion and the convex portion are reversed.

ない。In the fixed contact plates 310, 320, the drawing terminals 316, 326 are shown as being drawn out directly from the central portions 314, 324, but may be made to protrude directly from one end of the insertion portions 313, 323. Further, even if the guide groove 2211 of the insertion groove 221 is cut out to one surface of the lower substrate 220, the effect will not be impaired.

させたｔａ継電路が得ら扛る。As explained above, according to the present invention, electrical contacts are provided on the flat surface of one end of the conductive plate to form a fixed contact plate, and the lead terminal of the fixed contact plate is arranged to protrude from inside the lower board. In addition, a TA relay path is obtained in which the current carrying capacity of the contacts and the dielectric strength between the fixed contact plate and the excitation winding are increased to expand and improve the range of use.
