Connector

A floating connector comprises a movable housing, a regulating member and a plurality of contacts. Each of the contacts is made of a single metal plate. Each of the contacts has a fixed portion, a regulated portion, a held portion, an extending portion, a contact portion and a coupling portion. The coupling portion is resiliently deformable. The movable housing is movable within a predetermined range in a plane perpendicular to an up-down direction by the resilient deformation of the coupling portion. The coupling portion has a first portion, a second portion and a bent portion. Each of the first portion and second portion has a principal surface. The principal surface of the first portion faces in a first direction. The principal surface of the second portion faces in a second direction. The first direction and the second direction are different from each other.

Floating connector

A floating connector comprises a movable housing, a plurality of contacts and at least one ground member. Each of the contacts has a fixed portion, a first held portion, a coupling portion, an extending portion and a contact portion. The coupling portion is resiliently deformable. The movable housing is movable within a predetermined range in a plane perpendicular to an up-down direction by the resilient deformation. The contacts include a plurality of ground contacts and a signal contact. The ground member has a plurality of ground contact portions, a plurality of supporting portions, a ground coupling portion and a second held portion. The ground contact portions correspond to the ground contacts, respectively. Each of the ground contact portions is brought into contact with the corresponding ground contact even when the movable housing is moved within the predetermined range. The ground coupling portion couples the supporting portions with each other.

A floating connector is provided with a plurality of contacts, at least one stub member and a movable housing. The movable housing has a first holding portion and a second holding portion. The first holding portion holds first held portions of the contacts, and the second holding portion holds a second held portion of the stub member. The at least one stub member corresponds to at least one of the contacts in one-to-one correspondence. A stub contact point is always pressed against a coupling portion of the contact corresponding to the stub member even when the movable housing is moved within a predetermined range.

A contact realizing excellent transmission of high-speed signals by reducing a transmission path length and electric influence of adjacent contacts. In a first housing disposed on a circuit board, a second housing is fitted for receiving a mating connector therein in a manner movable in a moving direction orthogonal to a receiving direction. Each contact includes a contact portion brought into contact with an associated mating contact of the mating connector, a connection portion connected to the circuit board, and an elastically deformable linking portion connecting the contact and connection portions. The second and first housings hold the contact and connection portions, respectively. A dimension A of the linking portion in the receiving direction and a dimension B of the linking portion in a front-rear direction orthogonal to both the receiving and contact arranging directions is set to e.g. A&#x3e;B.

A connector is attachable to a front end of a cable in a front-rear direction. The cable comprises coated signal cables and an outer member which protects the signal cables. The connector comprises terminals, a holding member, a shell, an assigned portion and an impedance adjusting portion. The terminals are attached to the signal cables, respectively, under an attached state where the connector is attached to the front end of the cable. The holding member holds the terminals. The shell covers the holding member to have a predetermined surface which intersects with a perpendicular direction perpendicular to the front-rear direction. The assigned portion is located on the outer member of the cable under the attached state. The impedance adjusting portion is located forward of the assigned portion in the front-rear direction and located inward in the perpendicular direction in comparison with both the predetermined surface and the assigned portion.

A connector comprises a shell fixed portion connected to a shell, a ground contact and a differential pair consisting of two signal contacts. The ground contact has a ground fixed portion. Each signal contact has a signal fixed portion. The shell fixed portion, the signal fixed portions and the ground fixed portion are fixed to the circuit board when the connector is used. The shell fixed portion, one of the signal fixed portions, a remaining one of the signal fixed portions, the ground fixed portion form a fixed-portion group in which they are adjacent to one another in this order. Moreover, the ground fixed portion and the signal fixed portions are arranged in a row along a pitch direction. When the fixed-portion group is seen along the pitch direction, at least a part of the shell fixed portion occupies an area same as a part of the signal fixed portion.

A differential amplifier generates an offset correction signal based on a rotation detection signal from a rotation detector apparatus and an offset signal. A comparator compares the offset correction signal with a threshold voltage, and outputs a binarized signal representing the comparison result. An average value signal generator circuit generates an average value signal representing the average value of the offset correction signal. The offset signal generator circuit generates the offset signal so that the signal voltage of the average value signal has a voltage value between a threshold voltage and a threshold voltage.
