Electrical connector for circuit boards and circuit-board-mounted electrical connector

An electrical connector for circuit boards comprising:

• a terminal including a connecting portion for connection to a circuit board, the connecting portion being disposed on one end of the terminal, and a contact portion for contact with a counterpart connector element, the contact portion being disposed on the other end of the terminal;
• and
• a housing retaining the terminal, the housing including a stationary housing for mounting to the circuit board through the terminal and a movable housing movable relative to the stationary housing and receiving the contact portion of the terminal, wherein
• the terminal includes a stationary-side retained portion retained by the stationary housing, a movable-side retained portion retained by the movable housing, and an elastic portion located between the stationary-side retained portion and the movable-side retained portion and elastically deformable,
• the electrical connector for circuit boards further comprises a relay member configured as a member separate from the terminal, and
• the relay member makes contact with the terminal at both a position closer to the one end than the elastic portion is and a position closer to the other end than the elastic portion is to constitute a signal transmission path shorter than a total length of the elastic portion and short-circuits parts located at both the positions.

A circuit-board-mounted electrical connector comprising:

• a circuit board;
• and
• an electrical connector mounted on the circuit board, wherein
• the electrical connector includes a terminal including a connecting portion for connection to the circuit board, the connecting portion being disposed on one end of the terminal, and a contact portion for contact with a counterpart connector element, the contact portion being disposed on the other end of the terminal, and a housing retaining the terminal, the housing including a stationary housing for mounting to the circuit board through the terminal and a movable housing movable relative to the stationary housing and receiving the contact portion of the terminal,
• the terminal includes a stationary-side retained portion retained by the stationary housing, a movable-side retained portion retained by the movable housing, an elastic portion located between the stationary-side retained portion and the movable-side retained portion and elastically deformable, and a relay contact portion disposed at a position closer to the other end than the elastic portion is,
• the circuit board includes a circuit portion exposed on a mounting surface of the circuit board, the circuit portion including a first pad contactable with the connecting portion, a second pad contactable with the relay contact portion, and a signal transmission portion shorter than a total length of the elastic portion and connecting the first pad and the second pad, and
• the relay contact portion and the circuit portion constitute a signal transmission path shorter than the total length of the elastic portion and short-circuit a part of the terminal located at a position closer to the other end than the elastic portion is and the second pad of the circuit portion in a state where the electrical connector is mounted on the circuit board.
