According to an embodiment, it is possible to provide an electronic device including: a housing; a first printed circuit board disposed in the housing; a second printed circuit board disposed in the housing and spaced apart from the first printed circuit board; a first flexible printed circuit board electrically connecting the first printed circuit board and the second printed circuit board; and a second flexible printed circuit board electrically connecting the first printed circuit board and the second printed circuit board, in which the second flexible printed circuit board may be longer than the first flexible printed circuit board. Other embodiments are also disclosed.

A connector module, which includes a male connector having a first housing and first terminals accommodated in the first housing; a female connector having a second housing configured such that the first housing is fitted therein and second terminals accommodated in the second housing and a connector connection detecting unit having a pressure sensor configured to contact at least one side of the first housing when the first housing is entirely fitted into the second housing, the connector connection detecting unit being configured to transmit a connection state of the male connector and the female connector to an external device.

An apparatus includes a body with an opening through the body, the opening corresponding to dimensions of a cable to be connected to a circuit board and a flat surface to abut the circuit board. The apparatus further includes one or more attachment mechanisms to attach the body to the circuit board.

A wire end connector and a connector assembly with the wire end connector are provided. The wire end connector comprises a wire end connector body, a wire end housing, and an unlocking member. The wire end housing comprises a wire end accommodating part and two buckling bumps. An end surface of the wire end accommodating part in a first direction comprises a wire end opening. An outer surface of the two buckling bumps in a second direction orthogonal to the first direction and away from the wire end accommodating part respectively comprises a buckling recess. The unlocking member comprises two opposite unlocking arms. An outer side edge of the two unlocking arms comprises a wire end buckling part and an unlocking part. The unlocking member is configured to cause the unlocking parts to releases the wire end buckling part to a release position.

A housing of a connector has end faces at both ends thereof in a pitch direction. The end faces correspond to protruding blocks of a mating connector 50, respectively. Two guide members are distinct and separated from each other. Each of the guide members has a side portion and two supporting portions. The guide members correspond to the end faces, respectively. Accordingly, the side portion and the supporting portions correspond to one of the end faces. The side portion is located apart from the end face corresponding thereto in the pitch direction. The side portion, the supporting portions and the end face corresponding to the side portion form a receiving portion. The receiving portion guides and receives the protruding block corresponding to the end face forming the receiving portion when the connector and the mating connector are mated with each other.

A wire-clamping connector assembly includes a wire-clamping connector and a mating connector that are mated with each other. The wire-clamping connector includes a casing and a conductive cable. The casing includes a first wire-fixing portion, a second wire-fixing portion, and a third wire-fixing portion that is located therebetween. A first gap is formed between the first wire-fixing portion and the third wire-fixing portion, and a second gap is formed between the second wire-fixing portion and the third wire-fixing portion. The conductive cable includes a conductive cable body and insulating bodies that cover the conductive cable body. The conductive cable passes through the first gap and the second gap, such that a third extension section is surroundingly arranged below the third wire-fixing portion. An extension direction of the conductive cable is perpendicular to a mating direction of the mating connector and the wire-clamping connector.
