Electrical connector for circuit board
An electrical connector with terminals having contact portions that come into contact with a connected circuit board and a housing that supports the terminals. The housing has a stationary housing for attaching to a circuit board and a movable housing configured to move with respect to the stationary housing. The connecting circuit board contacts the contact portions on the movable housing side. The terminals each have a stationary-side supported portion that is supported by the stationary housing, a movable-side supported portion that is supported by the movable housing, and an elastic portion that links the stationary-side supported portion and the movable-side supported portion. The elastic portions each have longitudinal portions extending in the connector mating direction, and a lateral portion extending in a direction perpendicular to the mating direction, and reach the stationary-side supported portions via bent portions that are bent at the inner ends of the lateral portions.
1. An electrical connector for a circuit board, comprising:
terminals on which connection portions for connecting to the circuit board are formed on one end side and contact portions for making contact with a counterpart connected circuit board are formed on the other end side, and
a housing that supports said terminals, said housing having a stationary housing for attaching to the circuit board via the terminals, and a movable housing that is formed as a separate member from the stationary housing and is able to move with respect to the stationary housing, and said counterpart connected circuit board coming into contact with the contact portions of the terminals on the movable housing side,
wherein each of the terminals has a stationary-side supported portion that is supported by the stationary housing, a movable-side supported portion that is supported by the movable housing, and an elastic portion that links the stationary-side supported portion and the movable-side supported portion and is capable of elastic displacement, and
each of the terminals elastic portion has longitudinal portions extending in a mating direction of the electrical connector with the counterpart connected circuit board, and a lateral portion extending in a direction perpendicular to the mating direction, and bent portions are formed by being bent at inner ends of the lateral portion;
wherein at least a portion of the longitudinal portions is located inside the movable-side housing in the mating direction.
2. The electrical connector for a circuit board according to claim 1 , wherein the elastic portion of each of the terminals has the longitudinal portions, the lateral portion, and the bent portion at the inner end of the lateral portion linked in that order to the movable-side supported portion, and the bent portion is linked to the stationary-side supported portion.
3. The electrical connector for a circuit board according to claim 1 , wherein the longitudinal portions of each of the terminals are formed longer than the lateral portion.
4. The electrical connector for a circuit board according to claim 1 , wherein a pair of said terminals is such that the movable-side supported portion of said terminals are located more to an inside in a connector width direction than the stationary-side supported portion.
5. The electrical connector for a circuit board according to claim 1 , wherein at least the elastic portions of the terminals are bent in a sheet thickness direction of the terminals.
