Abstract: A multipolar connector capable of easily assembling components thereof without requiring high positional accuracy for portions of the components that are to be fixed to each other. A multipolar connector is a multipolar connector for use in electrically connecting circuit boards to each other. The multipolar connector includes an external terminal that is fixed to a circuit board, an insulating member that is fixed to the external terminal, and internal terminals that are respectively fitted to grooves, which are formed in the insulating member, so as to be partially exposed through the insulating member. The insulating member is placed such that the bottom surface thereof is in contact with an outer frame portion of the external terminal and fixed to the external terminal as a result of the top surface thereof being pressed by bending portions of the external terminal toward the outer frame portion.

Abstract: A connector set includes a first connector and a second connector. The first connector has a plurality of first connection terminals, a first anchoring terminal, and a first insulative member, and the second connector has a plurality of second connection terminals, a second anchoring terminal, and a second insulative member. When the first connector and the second connector are coupled, the plurality of first connection terminals and the plurality of second connection terminals respectively make contact at the first contact portions and the second contact portions. The first anchoring terminal and the second anchoring terminal make contact with each other to maintain the coupling between the first connector and the second connector, and have a ring shape that encircles a periphery of the first contact portions and the second contact portions when the first connector and the second connector are coupled.

Abstract: An outer peripheral surface of a first anchoring terminal has a first surface facing one side of a second direction and a second surface facing one side of a third direction in a first corner portion, and a third surface facing the other side of the second direction and a fourth surface facing the other side of the third direction in a second corner portion. An inner peripheral surface of a second anchoring terminal has a fifth surface facing the other side of the second direction and a sixth surface facing the other side of the third direction in the first corner portion, and a seventh surface facing the one side of the second direction and an eighth surface facing the one side of the third direction in the second corner portion. The first to fourth surfaces make contact with the fifth to eighth surfaces, respectively.

Abstract: A connector, which can protect a photoelectric conversion device from noise and has high durability includes a plug provided at one end of an optical fiber and a receptacle to which the plug is mounted from above. The plug includes a photoelectric conversion device composed of a semiconductor device that is not covered with a metal case and a metal member provided so as to cover an upper side of the photoelectric conversion device. The receptacle includes a metal housing to which the plug is fixed. The plug and the receptacle are fixed to each other only by engagement between the metal member and the metal housing.

Abstract: A receptacle includes a main body having an opening surrounded by sides such that the plug can be attached therein. Holding members are located at opposite ends of the sides to fix the plug. At least one spring terminal is configured to be electrically connected to the plug and is U-shaped to have a turn-back portion when viewed from above. A distal end of the turn-back portion is located at a position shifted outward from the opening, and a contact portion is located in the opening when viewed from above. A fixed portion of the spring terminal is located at a position shifted outward from the opening when viewed from above. A portion of the spring terminal opposed to a holding member is bent in a direction away from the holding member.

Abstract: In a coaxial connector, signal lines are switched over by mounting and dismounting a probe having a central contact, and fixed yoke terminals, a movable terminal, and a permanent magnet constitute a magnetic circuit. When the probe is dismounted, the contact portions are connected by the magnetic force of the permanent magnet. When the probe is mounted, the contact portions are disconnected against the magnetic force such that the central contact pushes a protrusion portion of the movable terminal.
