The terminal fitting 20 is inserted into the connector housing 11, and the extension member 30 is temporarily locked to the connector housing 11. In this state, the operating portion 33 of the extension member 30 is in a position not interfering with the flexible pressing piece 17, and the flexible pressing piece 17 does not press the bending portion 23A, so that the flexible connecting piece 23 is bent.

Furthermore, the terminal insertion opening 14 facing the board connection terminal 25
Is covered by the cover 31 of the extension member 30. Therefore, even if the board connector 10 is stored or transported in a bag or the like together with a large number of other board connectors 10, only the connector housings 11 that are relatively hard to deform need to hit each other. There is no possibility that the easily deformable board connecting terminal 25 will interfere with another connector housing 11 or the like.

滑に行われる。When the board connector 10 is attached to the circuit board P, the extension member 30 in the temporary locking position is moved to the main locking position. Then, the operating portion 33 causes the inclined surface 17 to move.
The flexible pressing piece 17 is brought into contact with B and pushed toward the cavity 12, and the bending portion 23A is pressed by the flexible pressing piece 17 and the flexible connecting piece 23 is deformed so as to expand (expand). With this extension deformation, the bent portion 23A pushes the pressing surface 17A.
Although it moves to the back side while rubbing the top, at this time, since the pressing surface 17A inclines in the direction to the back side by changing the posture of the flexible pressing piece 17, the sliding contact of the bent portion 23A The operation, that is, the extensional deformation of the flexible connecting piece 23 is smoothly performed.

Then, the board connecting terminal 64 relatively penetrates the through hole 72 and projects to the outside of the cover member 70, whereby the board connecting terminal 64 is ready to be inserted into the through hole H. In this state, the board connector 50 is attached to the circuit board P. For attachment, the cover member 70 is positioned at a predetermined position on the circuit board P, and the board connection terminals 64 are inserted into the through holes H.

ている。As described above, the board connector 50 of this reference example can be kept in a state in which the board connecting terminals 64 are hidden in the cover member 70 while the board connector 50 is not attached to the circuit board P. It is possible to prevent other members from interfering with the board connection terminal 64 during transportation or transportation. In addition, the stress relaxation portion 63 is provided between the terminal body 61 and the board connection terminal 64.
Since the terminal main body 61 is displaced toward the circuit board P side due to the fitting resistance with the mating male terminal fitting 60 after mounting on the circuit board P, the stress relaxation portion 63 is elastic. It is designed to bend and absorb the deviation. As a result, an increase in stress in the soldered portion (not shown) between the board connection terminal 64 and the circuit board P is avoided.
