Abstract: It is aimed to reduce a size in an arrangement direction of a plurality of terminal groups. A connector (10) is provided with an inner module (11) including a plurality of terminal groups (22) each having a pair of terminals (60) to be respectively connected to a pair of conductive paths (71), and an outer housing (12) for accommodating the inner module (11). The inner module (11) includes an inner housing (21) integrally configured to support the plurality of terminal groups (22). The outer housing (12) includes one accommodation chamber (84) for accommodating the inner module (11).

Abstract: A grip includes a core that forms a structure of the grip and has electrical conductivity, a sensing electrode for detecting a biological signal of a user, and a ground electrode that is connected with a reference voltage portion. The core, the sensing electrode and the ground electrode are insulated from one another. The core is disposed inside the grip, and the sensing electrode is exposed on a surface of the grip. The sensing electrode and the core are connected with one another via a voltage follower circuit. The ground electrode is located at such a position that the core is able to reduce a parasitic capacitance which would be formed between the ground electrode and the sensing electrode.

Abstract: In order to achieve impedance matching, a connector (A) is provided with: a housing (10) having terminal receiving chambers (11) disposed in two rows; two short-circuit members (30) which are attached to a plurality of terminal receiving chambers (11) arrayed in one row and a plurality of terminal receiving chambers (11) arrayed in the other row, and which constitute a differential pair; a plurality of terminal fixtures (40) which are separately fixedly attached to a main line (51) constituting the differential pair and a sub-line (52) constituting the differential pair, and which are inserted into the terminal receiving chambers (11) and are thereby connected to the short-circuit members (30); and a plurality of lances (13) formed on the housing (10) to prevent removal of the terminal fixtures (40) inserted into the terminal receiving chambers (11).
