。After the hook-shaped engaging portion 3 is engaged with the engaging portion 4 on the base 1 side, the cover 2 is attached to the base 1 by hooking the leaf spring 7 between the opening 5 and the jaw portion 6. It is installed.
上記ベース１内には可動鉄心８、コイル１０、固定鉄心
９、および紙面と垂直方向２個所にコイル端子１１をそ
れぞれ収納配設し、またカバー２内にはクロスパー１２
を設けている。Inside the base 1, a movable iron core 8, a coil 10, a fixed iron core 9, and coil terminals 11 are housed at two locations perpendicular to the plane of the drawing.
has been established.
このクロスパー１２は複数個の可動接触子１３を備え、
各可動接触子１３はそれぞればね１４によってカバー２
に固定した固定接触子１５側に附勢されている。This cross spar 12 includes a plurality of movable contacts 13,
Each movable contact 13 is connected to the cover 2 by a spring 14, respectively.
The fixed contact 15 side fixed to the terminal is energized.
なお、１６はクロスパー１２の引外しは゛ね、１７はク
ロスパー１２の摺動案内部、１８は絶縁カバーである。In addition, 16 is a tripping part of the cross spar 12, 17 is a sliding guide portion of the cross spar 12, and 18 is an insulating cover.
さらに、カバー２には２個所の鉤形係合部３のそれぞれ
の内側に沿わせて第２図に示す形状の２つの接続用端子
１９を配設固定し、ベース１内に延びる各接続用端子１
９の内部末端はベース１内に収納したコイル端子１１に
接触させ、また外部の末端にはファストン端孔２０を接
続している。Furthermore, two connection terminals 19 having the shape shown in FIG. Terminal 1
The inner end of 9 is brought into contact with a coil terminal 11 housed in the base 1, and the outer end is connected to a faston end hole 20.
このような構成を有する従来の電磁接触器では、保守点
検による分解時やファストン端子の引抜時に不用意な取
扱いをすると、カバー２の鉤形係合部３に大きな力が加
わってこれを折損させてしまうことがあった。In a conventional electromagnetic contactor having such a configuration, if it is carelessly handled when disassembled for maintenance inspection or when the Faston terminal is pulled out, a large force is applied to the hook-shaped engaging portion 3 of the cover 2, causing it to break. There were times when I ended up.
本考案はこのような欠点を改善するためになされたもの
で、鉤形係合部の内側に配設した接続用端子に着目して
これに一体に鉤形係合部の頭部を支持補強する支持部を
形成することにより、極めて簡単に上記駒形保合部の折
損を防止できるようにしたものである。The present invention has been made to improve these drawbacks, and focuses on the connection terminal arranged inside the hook-shaped engagement part, which integrally supports and reinforces the head of the hook-shaped engagement part. By forming the supporting portion, it is possible to extremely easily prevent the piece-shaped retaining portion from breaking.
以下図示実施例について本考案を説明する。The invention will now be described with reference to the illustrated embodiments.
本考案に係る接続用端子１９には第４図に示すように支
持部１９ ａを一体に形成してあり、第３図に示すよう
に、この接続用端子１９をカバー２に取付けた状態では
、上記支持部１９ ａが鉤形係合部３の頭部下側面にそ
の下方から重合している。The connecting terminal 19 according to the present invention is integrally formed with a support portion 19a as shown in FIG. 4, and as shown in FIG. , the support portion 19a overlaps the lower surface of the head of the hook-shaped engaging portion 3 from below.
なお、このような構成は２個の接続用端子１９（第５図
参照）について採用していることは勿論である。It goes without saying that such a configuration is adopted for the two connection terminals 19 (see FIG. 5).
またその他の構成は従来のものと同一であって、従来と
同一部分には同一符号を付して示しである。The rest of the structure is the same as the conventional one, and the same parts as the conventional one are denoted by the same reference numerals.
したがって本考案においては、カバー２の取外しや接続
用端子１９に接続したファストン端子２０の引外し時等
