DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin jack which can be used for transmitting electric signals of electric equipment.

[0002]

2. Description of the Related Art Conventionally, a pin jack is integrally molded in a resin cover, or a single product is fixed to a cover and then inserted into a printed circuit board, or a single product is printed. After insertion into the board, a cover is put on and the cover and the single pin jack are fixed so as not to separate from each other.

However, in the case of repair, there is a problem that all the solder must be removed because the printed board and the pin jack are soldered.

Further, when the cover and the pin jack are not fixed, when the male jack is inserted and removed, an extra force is applied to a soldered portion between the printed circuit board and the pin jack, thereby causing a problem that a crack is generated.

The present invention is intended to solve such a conventional problem, and provides a pin jack which can maintain strength by inserting the pin jack alone into a printed circuit board and covering the cover from above. The purpose is to do so.

[0006]

SUMMARY OF THE INVENTION A pin jack of the present invention has a structure in which, when inserted into a printed circuit board, a bent portion which bends in the insertion direction is provided on an outer contact, and an inner contact slides in an insulating portion. I have. Alternatively, the inner contact has a bent portion that bends in the insertion direction when inserted into the printed circuit board, and the cover is inserted when the cover is inserted.
Is a pin jack characterized in that it is bent from the point of contact with the lead terminal until the insulating portion contacts the printed circuit board.

[0007]

According to the pin jack of the present invention, the cover can be easily formed.
Can be inserted and removed, and the connection can be easily and reliably performed without generating cracks or the like in the soldered portion.
