Abstract: A multipolar connector includes first and second connectors. The first connector includes first internal terminals, first external terminals connected to a ground potential, and a first insulating member that holds the first internal terminals and the first external terminals. The second connector includes second internal terminals, second external terminals connected to the ground potential, and a second insulating member that holds the second internal terminals and the second external terminals. In a state in which the first connector and the second connector fit together, the first internal terminals are connected to the second internal terminals, and each of the first external terminals is connected to the corresponding one of the second external terminals in such a manner that connection portions defined by the first external terminal and the second external terminal are visible from the corresponding one of sides on which end surfaces of the first connector are located.

Abstract: When a multipole connector set is viewed from a height direction and when a first ground terminal assembly, a first signal terminal assembly, and a second ground terminal assembly are arranged in a length direction as follows: A connection portion at the outermost side in a width direction of the first ground terminal assembly is a first connection portion, a connection portion at the outermost side in the width direction of the second ground terminal assembly is a second connection portion, a connection portion arranged at the innermost side in the width direction of the first ground terminal assembly is a third connection portion, and a connection portion at the innermost side in the width direction of the second ground terminal assembly is a fourth connection portion. All connection portions of the first signal terminal assemblies are inside a quadrangle connecting the first, second, third and fourth connection portions.

Abstract: A female electrical connector includes internal terminals, an external terminal surrounding the internal terminals, and a holding member that holds the internal terminals and the external terminal and extends in a long-side direction (X axis direction) and a short-side direction (Y axis direction). The internal terminals are arranged in the long-side direction. The external terminal includes a first contact wall portion closer than the internal terminals to a corner in the long-side direction and a second contact wall portion closer than the internal terminals to a corner in the long-side direction. The first and second contact wall portions face each other in the short-side direction. The holding member includes a first restricting portion close to the first contact wall portion to compensate for misalignment in a mated state and a second restricting portion close to the second contact wall portion to compensate for misalignment in the mated state.

Abstract: A connector includes a plurality of inner terminals and an outer terminal. The plurality of inner terminals are arrayed with intervals therebetween in a direction. The plurality of inner terminals are terminals that are connected to a ground potential. The outer terminal is disposed around the group of the plurality of arrayed inner terminals and are connected to a ground potential. The outer terminal includes side wall members that are shaped so as to extend in the direction and be parallel to the plurality of inner terminals. The inner terminals include connection parts that are connected to the side wall members.

Abstract: An electrical connector that includes a plurality of inner terminals that are arrayed in a first direction and extend in a second direction, an insulating member that has a terminal holding part that holds the inner terminals, and an outer terminal that surrounds the inner terminals when viewed in a third direction. The terminal holding part includes an insulating extending part that extends in the first direction. The outer terminal includes an outer extending part that extends in the first direction while being spaced apart from the insulating extending part along at least part thereof. An opening that extends in the first direction is formed between the insulating extending part and the outer extending part. The states of inner mounting parts of the inner terminals can be checked through the opening.

Abstract: A non-reciprocal circuit element includes a ferrite to which a direct current magnetic field is applied by permanent magnets, and first and second central electrodes arranged on the ferrite so as to cross each other while being insulated from each other. One end of the first central electrode is connected to an input port and another end thereof is connected to an output port. One end of the second central electrode is connected to the output port and another end thereof is connected to ground. A first capacitor is connected between the input port and the output port and a second capacitor is connected between the output port and ground. A resistor is connected between the input port and the output port and a third capacitor and an inductor are connected in series with the resistor R. A fourth capacitor is connected between the input port and ground. Capacitances of the first capacitor and the third capacitor are variable.
