ABSTRACT:
A circuit board connector for improving the reliability in the electrical connection of a joint section between a circuit board and a terminal, includes a housing and a pair of flexible arms extending downwards in the housing and adapted to lock a connection terminal with the housing, a slit-like gap being provided between the two flexible arms, semi-ellipsoidal engagement protrusions being provided on the arms at positions where they are opposed to each other. The connection terminal has a substantially rhombic engagement hole which is to be engaged with the engagement protrusions. When the flexible arms in the housing undergo thermal expansion as a result of a rise in temperature, the engagement protrusions move downwards while remaining in abutment with oblique inner edges of the engagement hole, thereby absorbing dimensional changes of the housing. Thus, the terminal is not influenced by expansion/contraction of the housing, thereby ensuring a stable electrical connection without involving any damage to the joint section between the circuit board and the terminal.
