本発明はプリント基板に装着され、自動半田付けされる
電気部品に係り、自動半田付時のフラックス侵入を防ぐ
構造の電気部品を供給するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrical component that is mounted on a printed circuit board and automatically soldered, and provides an electrical component that has a structure that prevents flux from entering during automatic soldering.

４はフォーミングされ、プリント基板（図示せず）の穴
に挿入される時スナップインできるようになっている。The first example of this type of electrical component in the past is a switch.
This will be explained with figures. In the figure, 1 is a metal terminal 2-1
~ 2-4 is a resin mounting base made by insert molding, and terminals 2-1 to 2-4 are partially located in the recess of the mounting base 1 and serve as fixed contacts. The terminals 2-1 to 2-4 are electrically connected to each other by pressing a button (both not shown) using a reversible metal diaphragm housed in the recess. Above terminals 2-1 to 2-
4 is formed so that it can snap in when inserted into a hole in a printed circuit board (not shown).

Reference numeral 4 denotes a switch positioning protrusion, which is also provided on the lower surface of the mounting base 1 and is engaged with a hole in the printed circuit board. 6-1~5-
Reference numeral 3 denotes a pin hole remaining after the remaining molding pins (not shown) that support the terminals 2-1 to 2-4 during insert molding, and faces the lower surface of the handling stand 1.

。Now, when such a switch is attached to a printed circuit board and automatically soldered, liquid flux ejected by automatic flux during soldering (during soldering) enters through the hole in the printed circuit board that fits into the positioning protrusion 4.At this time, This flux flows into the pin holes 6-1 to 6-3 and enters the inside of the switch, potentially causing a malfunction in the switch.
本発明は上記のようなフラックスの侵入を防ぐ構造の電
気部品を提供するものである。The present invention provides an electrical component having a structure that prevents flux from entering as described above.
以下、本発明の一実施例について第２図とともに上記と
同一箇所には同一番号を付して説明する。Hereinafter, one embodiment of the present invention will be described with reference to FIG. 2, with the same numbers assigned to the same parts as above.

ている。As shown in FIG. 2, in the present invention, a bank-shaped pedestal 6 is formed around the positioning protrusion 4 with a small gap therebetween and forms a bonding surface with a printed circuit board (not shown).
It also works to stop flux ejected from the fitting hole during soldering, and prevents flux from entering the inside of the switch from pin holes 01 to 5-3. Also, 7 is the mounting base 1
The stand is integrally provided on the lower surface of the switch and is flush with the pedestal section 6 in order to stably mount the switch on the printed circuit board.

を囲むように堤状の台座部６ａを設けたものである。FIG. 3 shows another embodiment of the present invention, in which an embankment is provided around the entire circumference of the positioning protrusion 4 in order to reduce flux intrusion into other adjacent electrical components on the same printed circuit board on which the switch is mounted. A shaped pedestal portion 6a is provided.
本発明によれば、特に特殊な構造を採用することなく、
フラックス侵入の不具合のないスイッチ等の電気部品を
実現することができるものである。According to the present invention, without adopting any special structure,
This makes it possible to realize electrical components such as switches that are free from the problem of flux intrusion.
