Even if such a board connector 10 is stored or transported in a bag or the like together with many other board connectors 10, the connector housings 11 that are relatively hard to break only need to hit each other, and are easily damaged. There is no possibility that the board mounting portion 23 interferes with another connector housing 11 or the like. Further, since the board mounting portion 23 is strongly pressed against the bending restricting piece 15 by the elastic restoring force of the stress relieving portion 22, an external force in the lateral displacement direction acts between the board mounting portion 23 and the bending restricting piece 15. However, a large frictional resistance is generated. Therefore, there is no possibility that the board mounting portion 23 comes off from the bending restricting piece 15.

Then, as shown in FIG. 2, the release contact portion 1 protruding from the connector housing 11.
5B abuts on the circuit board P, and the taper of the release contact portion 15B causes the bending restricting piece 15 to be forcibly elastically bent from the restricting position to the releasing position while making the posture slanted. As a result, the board mounting portion 23 is released from the retracted position by being disengaged from the deflection regulating piece 15, moves to the rear side by the elastic restoring force of the stress relieving portion 22, projects from the connector housing 11, and is inserted into the through hole H.

なく、操作性に優れている。As described above, the board connector 10 of the present embodiment can hold the board mounting portion 23 at the retracted position where it does not protrude from the connector housing 11 before the board connector 10 is mounted on the circuit board P. It is possible to prevent other members from interfering with the substrate mounting portion 23 during transportation or transportation. Further, when the connector housing 11 is mounted on the circuit board P, simply pressing the connector housing 11 against the circuit board P automatically releases the board mounting portion 23 from the retracted position and the through hole H
Therefore, it is not necessary to perform an operation of releasing the board mounting portion 23 prior to mounting on the circuit board P, and the operability is excellent.

The board connector 30 of the present embodiment is different from that of the first embodiment in the deflection restricting pieces (projection restricting means), a part of the terminal fittings, and the guiding portions. Other configurations are the same as those in the first embodiment, and thus the same configurations are denoted by the same reference numerals and description of the configurations will be omitted. The deflection restricting piece 35 of the second embodiment has an abutting portion 35A and a releasing abutting portion 35B as in the first embodiment.
7 is located lower than the floor surface 32B of FIG. In accordance with this, the board mounting portion 43 of the terminal fitting 40 is also formed so as to be located below the floor surface 32B in FIG. Further, the guiding portion 34 is formed in a groove shape in which the inner wall of the cavity 32 is cut out outside the floor surface 32B.
The stabilizer 24 is fitted into the fourth member 4.

形態１と同じなので、説明を省略する。In mounting the terminal fitting 40 to the connector housing 31 in the second embodiment, the terminal fitting 40
Is inserted straight along the floor surface 32A,
What is necessary is just to fit the stabilizer 44 into the guide part 34. During this time, the abutment portion 35A of the deflection restricting piece 35 is
7 is bent toward the release position as shown by the chain line in FIG. And
After the terminal main body 41 is locked by the lance 33, the substrate mounting portion 43 is pushed toward the terminal main body 41 by bending the stress relaxation portion 42 with a jig (not shown). When the leading end of the substrate mounting portion 43 passes through the abutment portion 35A, the bending restricting piece 3
5 is elastically restored to the regulation position. Then, the board mounting portion 43 moves by the elastic restoring force of the stress relieving portion 42 and hits against the bending restricting piece 35, so that the board mounting portion 43 is held at the retracted position where it does not protrude from the connector housing 31. Note that the procedure for attaching the circuit board to the circuit board and the functions and effects are the same as those in the first embodiment, and a description thereof will be omitted.

い。<Other Embodiments> The present invention is not limited to the embodiments described above and illustrated in the drawings. For example, the following embodiments are also included in the technical scope of the present invention. In addition, various changes can be made without departing from the scope of the invention. (1) In the above embodiment, as a means for holding the board mounting portion at the retracted position, the distal end of the board mounting portion is abutted against the bending restricting piece, which is the protrusion restricting means. A protrusion or the like provided at an intermediate position instead of the tip of the portion may be abutted against the protrusion restricting means, or a hole or a recess formed in the substrate mounting portion may be engaged with the protrusion restricting means.

行われるようになる。(2) In the above embodiment, the distal end of the board mounting portion is abutted against the deflection regulating piece. However, according to the present invention, a groove is formed in the deflection regulating piece instead of simply abutting. Alternatively, the tip of the substrate mounting portion may be fitted into the groove. By doing so, the reliability of the function of holding the board mounting portion at the retracted position is improved. (3) In the above-described embodiment, the releasing engagement portion of the deflection regulating piece is elastically displaced toward the releasing position by abutting on the flat surface of the circuit board.
On the circuit board side, a projecting portion or an inclined portion that can be engaged with the inclined surface of the release engaging portion may be provided. By doing so, the displacement operation of the deflection restricting piece to the release position is performed more smoothly.

い。(4) In the above-described embodiment, by providing the engagement portion for release on the flexure restricting piece, the flexure restricting piece is automatically moved to the position where the holding of the board mounting portion is released with the mounting operation to the circuit board. Although it is configured to be elastically bent, according to the present invention, the bending restricting piece is not provided with the releasing engagement portion, and the bending restricting piece is bent to the release position by an operation different from the mounting operation on the circuit board. You may. (5) In the above-described embodiment, the substrate mounting portion is released from the state held at the retracted position by elastically bending the bending restricting piece. However, according to the present invention, the projection restricting means does not bend. When the board mounting portion is released from the holding state at the retracted position, the board mounting portion itself may be bent so as to be disengaged from the projection restricting means.
