【発明の詳細な説明】 この発明唸装置電磁−電器の接点ブロックに関する。[Detailed description of the invention] The present invention relates to a contact block for a whirring device electromagnetic-electric appliance.

近年、電子回路素子の小蓋化に伴い、電磁継電器の小蓋
化も強く要請されている。しかして電磁継電器はその構
造が複雑で構成部品点数が多いため、小型化すると、そ
の組立製造のａｍが増す。In recent years, with the trend toward smaller lids for electronic circuit elements, there has been a strong demand for smaller lids for electromagnetic relays. However, since electromagnetic relays have a complex structure and a large number of component parts, miniaturization increases the amount of time it takes to assemble and manufacture them.

このため従来の小蓋化され良電磁継電器では、ネジ止め
、位置調整作業などを要さず単に嵌め合わせ中接着のみ
で簡単に且つ均一に組立製造できるようにするために、
複数の端子を予め正確に配置して絶縁材料でモールドし
て固定し、端子の他端側に接点などを堆付けて接点バネ
組みを構成した接点ブロックを用いている。For this reason, conventional small-lid electromagnetic relays do not require screw fixing, position adjustment, etc., and can be easily and uniformly assembled and manufactured by simply gluing during fitting.
A contact block is used, in which a plurality of terminals are precisely arranged in advance, molded with an insulating material and fixed, and a contact, etc. is deposited on the other end of the terminal to form a contact spring assembly.

着する作業も煩雑であった。However, in the contact block of this small electromagnetic relay, as mentioned above, the two fixed contact plate pieces 11 and 12 must be folded at different heights above the contact block 1, and the folding position cannot be adjusted. Fold the height accurately.
The work to do this was complicated. Further, the contact member 111. is attached to the opposing round surfaces of the two fixed contact plate pieces 11.12 by folding.
In order to secure the contact members 12L, K is a rounded shape that requires securing the contact members 11 & 121L to different sides of the protruding contact plate pieces 11 and 12, respectively, as shown in Figure 2.3 before folding. The work of fixing the contact members 111° and 121L was also complicated.

ｏａ、３９ｂが固着されている。One end of a movable contact spring 89 is fixed to the upper surface of the pedestal piece 32, as shown in #9@. Therefore, the other end of the movable contact spring 39 is located between the two fixed contact plate pieces 38 and 34, but due to its springiness, the upper fixed contact plate piece 33
It is touching the side. On the surfaces of the fixed contact plate pieces 38 and 34 facing each other, there are contact members aaas aha, respectively.
must be fixed. In this rounding, as shown in FIG. 6, since the solid contact plate pieces 3L 34 are collected on the upper and lower sides, each contact member 33a on the same side
, 34& are fixed and then bent so as to face each other. On both upper and lower surfaces of the movable contact spring 39, there are contact members a at nine positions corresponding to the contact members 33L and 34a, respectively.
oa and 39b are fixed.

によって凸部２８を強く保持させる。The fitting hole 25 of the insulating member 26 is formed at the base of the collecting book 0 that has been thrown at approximately the center of the surface 26b opposite to the terminal protruding surface. Then, the upper edge 2 of the fitting hole 25 is attached to the ninth part that firmly holds the protrusion 23 of the fitted yoke 22.
5& is bulged downward in a circular arc shape, and the convex portion 28 is strongly held by the elasticity of the upper edge portion 25a.

する。At the lower corner of the yoke 22, a 5-shaped armature 41 is superimposed, and below the armature 41, a nearly 5-shaped hinge spring 42 is superimposed, and in this state KTp, the insulating members 26.
Push through the fitting hole 25.25 of No. 6 and fit the protrusion 23.23. As shown in the figures, the end portion 41& of the armature 41 is located above the movable contact spring 89. When the coil of the electromagnet is energized and the iron core 211LK is attracted, the armature 41 presses the movable contact spring 39 downward.

Each terminal 27-3 on the underside of the cover 43 with 5-4B
If the terminal protruding surface zaat of the insulating member 26 is pushed in through the opening of the cover 43, the opening of the cover 43 will be opened. An adhesive is applied to the peripheral edge of the bottom lid 44 to fix the bottom lid 44 to the cover 43KII.

以上説明したように、この発＠による接点ブロックでは
、接点用板片が絶縁部材の互いに反対側へ集用している
ので、接点の取付けを同一面側から行うことができる。As explained above, in the contact block according to this invention, since the contact plate pieces are concentrated on opposite sides of the insulating member, the contacts can be attached from the same side.

し九がって従来の接点ブロックの場合のように一方０＠
点用板片に接点を取付は九後、接点ブロックを反転して

作業も簡単になる。Then, as in the case of conventional contact blocks, one side is 0@
After attaching the contacts to the point plate, there is no need to invert the contact block and attach the contacts to the other contact plate, which simplifies the work of the contact plate. Further, since the contact plate piece can be bent along the notch provided in the insulating member, the folding work is also simplified.
