Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a plug installed on a printed circuit board, with a plurality of female connectors.

BACKGROUND OF THE INVENTION Conventional electrical connectors can be broadly divided into two types: one is a header with male contacts, and the other is a plug with female contacts.

Conventionally, a plug has been known that has one end forming a female contact and the other end forming a terminal portion that extends through a hole provided in a printed circuit board and is soldered to a conductor on the printed circuit board. ing.

In addition, there are two types of plugs of this type: one in which the female contacts extend in a direction perpendicular to the plane of the printed circuit board when installed on a printed circuit board, and the other in which the female contacts extend parallel to this plane.

Problems to be Solved by the Invention In the conventional plug described above, the terminal portion extends through the hole in the printed circuit board, so a relatively large space is required, and there is a limit to the machining dimensions of the hole in the printed circuit board. Because of this, the pitch of the holes cannot be made very small, and for this reason,
Since the shape of the plug is affected, the size of the plug cannot be made sufficiently small, and does not meet the demand for making the most compact device. Another problem is that the installation is relatively troublesome.
