Description

The present invention relates to a connector, and more particularly to a connector that is attached to various devices and connects to a mating connector.

This type of connector is disclosed in, for example, Patent Document 1. As shown in FIG. 33, the connector 1 disclosed in Patent Document 1 has a structure in which a plurality of conductive contacts 3 are held in a metal housing 2. A flange 2A is formed so as to project from the outer peripheral portion of the housing 2, and the connector 1 is attached to the device by fixing the flange 2A to the casing of an electric device or an electronic device using a mounting screw or the like.

Further, the housing 2 has a tubular portion 2C in which a concave mating side connector accommodating portion 2B is formed therein, and the contact portion 3A arranged at one end of each contact 3 is a mating side connector accommodating portion. The connecting portion 3B projecting into the 2B and arranged at the other end of each contact 3 projects to the back surface side of the housing 2 and is connected to a wiring object such as a circuit board inside the device.
When the connector 1 is connected to the mating connector (not shown), a part of the mating connector is housed in the mating connector accommodating portion 2B of the tubular portion 2C along the fitting direction D, and the contact portions 3A of the plurality of contacts 3 are accommodated. Is connected to multiple contacts on the mating connector.

Japanese Patent No. 6013116

The contact portions 3A of the plurality of contacts 3 connected to the mating connector in this way often have an arrangement pattern defined by a standard or the like on a plane orthogonal to the fitting direction D. For example, in a so-called round connector in which the outer peripheral portion of the cylindrical portion 2C viewed from the fitting direction D is circular, the contact portions 3A of the plurality of contacts 3 occupy the positions of the four vertices of a rhombus or a square. May be placed.
