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: 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: 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: 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: 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: In a non-reciprocal circuit element, the characteristics variation with respect to temperature is suppressed with a simple configuration without changing a magnetic material or the material of a magnet. A non-reciprocal circuit element includes: a magnetic material (32) to which a DC magnetic field (G) is applied; a plurality of center electrodes (35, 36) disposed on the magnetic material (32) so as to intersect each other in an insulated state; a terminal resistor (R) connected between input and output ports (P1, P2) and in in parallel with one of the center electrodes (35, 36); a variable capacitance element (C11) connected between the input and output ports (P1, P2) and in parallel with the terminal resistor (R); and a thermistor element (S) connected to a control power supply circuit (E) of the variable capacitance element (C11) and in series with the variable capacitance element (C11).

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.
