In the first connector, a first contact point portion, a first indented portion, a first lock portion and a regulated portion of a first terminal are supported by a spring portion. A first holding member holding the first terminal has a regulating portion. The regulated portion is located downward of the regulating portion and faces the regulating portion. In the second connector, a second terminal held by a second holding member has an insertion end portion, a second contact point portion, a second indented portion and a second lock portion. In a mated state, the first lock portion and the second lock portion are located between the first indented portion and the second indented portion and face each other in the up-down direction.

Abstract: A ring laser gyroscope includes an optical block for generating laser beams that counter-propagate in a closed-loop type optical path, a dither mechanism for applying dither vibration for mitigating a lock-in phenomenon to the optical block, and a dither controller for controlling the dither vibration. The dither controller imparts randomness to the frequency of the angular velocity of the dither vibration.

Abstract: A connector comprises a housing having a bottom portion and terminals including inner terminals. The bottom portion has a projecting portion and two base portions. The projecting portion projects from the base portions in an upper-lower direction (Z-direction). Each of the base portions has at least one predetermined portion. The predetermined portion includes two passing holes and a separating portion. Each of the passing holes passes through the base portion in the upper-lower direction. The separating portion separates the two passing holes from each other in the pitch direction (Y-direction) and is connected to the projecting portion in the lateral direction (X-direction). Each of the inner terminals has a solderable portion. The solderable portions are partially located in the passing holes, respectively.

Abstract: A device comprises a first circuit member, a second circuit member and a third circuit member. The first circuit member comprises a first body for performing the function of the first circuit member and a first flexible board formed with a first integrated-electrode portion including first electrodes. The second circuit member comprises a second body for performing the function of the second circuit member and a second flexible board formed with a second integrated-electrode portion including second electrodes. The third circuit member comprises a third body for performing the function of the third circuit member and a third flexible board formed with a third integrated-electrode portion including third electrodes. The first integrated-electrode portion, the second integrated-electrode portion and the third integrated-electrode portion lie over each other in an upper-lower direction. The first body, second body and the third body are apart from each other when seen along the upper-lower direction.

Abstract: An assembly comprises a first connector and a second connector. The first connector is mateable with the second connector in an up-down direction. The first connector comprises a plurality of first terminals and a first holding member. Each of the first terminals has two pressed contact points and an insertion end portion. The first terminals include at least one primary first terminal and at least one secondary first terminal. The second connector comprises a plurality of second terminals and a second holding member. The second terminals correspond to the first terminals, respectively. Each of the second terminals has two pressing contact points. The second terminals include a primary second terminal and at least one secondary second terminal. A first size S1 and a second size S2 meet a condition of S1?S2, where S1=Sa?D1, and S2=Sb?D2.

Abstract: A connector is provided with terminals, a holding member and holddowns. The holding member has two side portions, two accommodation portions and an island portion. In a pitch direction (X-direction), the accommodation portions are located within a range not larger than the island portion. The terminals are divided into two terminal rows, which correspond to the accommodation portions, respectively. Each of the holddowns has an end wall portion and two side coupling portions. The end wall portions are located at end portions of the connector, respectively, in the pitch direction (X-direction). Each of the side coupling portions couples the end wall portion to either one of the side portions of the holding member. In the up-down direction (X-direction), the holding member does not overlap with the end wall portion.

Abstract: A terminal of a connector has a receiving portion, a first supporting portion which is resiliently deformable and extends from the receiving portion, a contact portion supported by the first supporting portion, a second supporting portion extending from the contact portion and an abutment portion supported by the second supporting portion. In a connection process of the connector and a mating connector, the abutment portion of the terminal begins to be brought into contact with the receiving portion at a first position on the receiving portion, and it is slid on the receiving portion until the abutment portion reaches a second position. The contact portion is brought into contact with a mating terminal when the connector is connected to the mating connector.

Abstract: In a connector, a contact includes: a first connection portion and a second connection portion that are retained between a first insulator and a second insulator and face each other; and a pressing force receiving portion that makes contact with the second insulator and receives a pressing force from the second insulator to thereby press the first connection portion against the second connection portion. A connection object is sandwiched between the first connection portion and the second connection portion, and at least one of the first connection portion and the second connection portion makes contact with a flexible conductor of the connection object, whereby the contact is electrically connected to the flexible conductor of the connection object.
