Abstract

A circuit board electrical connector includes: a plurality of terminals; a fixed housing fixed to a circuit board via the terminals; and a movable housing relatively movable with respect to the fixed housing, in which the terminals are provided to be bridged between the fixed housing and the movable housing, the terminals include a fixed side held portion held by the fixed housing, a movable side held portion positioned on an inner side in a connector width direction than the fixed side held portion and held by the movable housing, and an elastically deformable intermediate portion positioned between the fixed side held portion and the movable side held portion, the intermediate portion includes at least one of elastic portions bent in a connector height direction, and a specific elastic portion of the elastic portions can abut on the fixed housing when being elastically deformed by a predetermined deformation amount.

Claims (59)

1. A circuit board electrical connector comprising:

a plurality of terminals;

a fixed housing fixed to a circuit board via the terminals; and

a movable housing relatively movable with respect to the fixed housing, wherein the terminals are provided to be bridged between the fixed housing and the movable housing, the terminals include

a fixed side held portion held by the fixed housing,

a movable side held portion positioned on an inner side in a connector width direction than the fixed side held portion and held by the movable housing, and

an elastically deformable intermediate portion positioned between the fixed side held portion and the movable side held portion,

the intermediate portion includes at least one of elastic portions bent in a connector height direction,

the at least one of elastic portions includes a specific elastic portion configured to abut on the fixed housing when being elastically deformed by a predetermined deformation amount,

the specific elastic portion has an inverted U shape as a whole,

the specific elastic portion includes two straight portions extending in the connector height direction and a bent portion having a downwardly bent shape coupling upper end portions of the two straight portions, and

the upper end portion of one of the two straight portions on an outer side in the connector width direction is configured to abut on the fixed housing when the specific elastic portion is elastically deformed by the predetermined deformation amount.

2. The circuit board electrical connector according to claim 1 , wherein

the fixed housing includes a side wall positioned on the outer side in the connector width direction than the specific elastic portion to have a range overlapping with the specific elastic portion of the intermediate portion in the connector height direction, and

the elastic portion is configured to abut on the side wall when being elastically deformed by the predetermined deformation amount outward in the connector width direction.

3. The circuit board electrical connector according to claim 1 , wherein

the intermediate portion includes a plurality of the elastic portions

and the plurality of elastic portions includes a movable side elastic portion that is an elastic portion positioned between the specific elastic portion and the movable side held portion besides the specific elastic portion.

4. The circuit board electrical connector according to claim 2 , wherein

the intermediate portion includes a plurality of the elastic portions

5. The circuit board electrical connector according to claim 1 , wherein

the fixed housing includes a top wall positioned to have a range overlapping in the connector width direction at a position on a side away from the circuit board in the connector height direction with respect to the specific elastic portion of the intermediate portion, and the specific elastic portion is configured to abut on the top wall when being elastically deformed by the predetermined deformation amount toward the side away from the circuit board in the connector height direction.

6. The circuit board electrical connector according to claim 2 , wherein

7. The circuit board electrical connector according to claim 3 , wherein

8. The circuit board electrical connector according to claim 4 , wherein

9. The circuit board electrical connector according to claim 1 , wherein

the movable housing is positioned on the inner side in the connector width direction than the specific elastic portion to have a range overlapping with the specific elastic portion of the intermediate portion in the connector height direction, and
