[Fixed part]
The connector 10 according to this embodiment comprises a single peg 50 for fixing the connector housing 20 to the circuit board 5, as shown in FIG. As shown in FIG. 9, the peg 50 is formed by bending a metal plate. A pair of fixing portions 51 are provided on both left and right sides of the peg 50 . As shown in FIGS. 1 and 2 , the pair of fixing portions 51 are attached to the pair of attachment portions 25 of the connector housing 20 . As shown in FIG. 4 , the lower end of the fixed portion 51 is soldered to the circuit board 5 .

[Connection support part]
As shown in FIG. 9 , the peg 50 includes a connection auxiliary portion 52 that connects upper rear ends of the pair of fixing portions 51 . That is, since the auxiliary connection portion 52 is formed integrally with the pair of fixed portions 51, the auxiliary connection portion 52 does not have to be provided separately, and the number of parts can be reduced. As shown in FIG. 4 , the front surface of the connection auxiliary portion 52 is a contact surface 53 that contacts the body portion 31 of the flexible cable 30 . The contact surface 53 is arranged so as to face the partition wall 23 . When the abutting surface 53 abuts on the main body portion 31 of the flexible cable 30, the flexible cable 30 extending in the front-rear direction is bent substantially at a right angle and extended downward. Thereby, the other end portion 33 of the flexible cable 30 can be brought into contact with the circuit board 5 . Specifically, since the flexible cable 30 has flexibility, the other end portion 33 of the flexible cable 30 bent to extend downward is deformed along the surface of the circuit board 5, and the lower surface of the board connection portion 35 is deformed. contacts the surface of the circuit board 5 .

As shown in FIG. 9, in the present embodiment, the lower end portion 54 of the connection auxiliary portion 52 is formed by bending the end portion of a metal plate material into a substantially U shape when viewed from the side, thereby forming a smoothly curved shape. . As shown in FIGS. 2 and 4 , the lower end portion 54 of the connection auxiliary portion 52 is the end portion of the connection auxiliary portion 52 arranged on the other end portion 33 side of the flexible cable 30 . Since the lower end portion 54 of the connection assisting portion 52 has a curved surface shape, even if the flexible cable 30 comes into contact with the lower end portion 54 of the connection assisting portion 52 when the peg 50 is assembled to the connector housing 20, the flexible cable 30 is less likely to be damaged. . On the other hand, if the lower end portion 54 of the connection auxiliary portion 52 is a fractured surface, it is conceivable that the flexible cable 30 may come into contact with the flexible cable 30 and be damaged.

[Manufacturing Method of Connector and Connector Mount]
The connector 10 and the connector package 1 of this embodiment are configured as described above, and a method for manufacturing the connector 10 and the connector package 1 will be described below.
The flexible cable 30 is formed by a known printed wiring technique. A plurality of terminal portions 43 are configured by bonding the flexible cable 30 and the reinforcing plate 40 with an adhesive. Here, the conductive path 36 arranged in each terminal connection portion 34 and each substrate connection portion 35 is exposed downward (see FIG. 6).

A plurality of terminal portions 43 are press-fitted into the through holes 26 of the connector housing 20 . The plurality of terminal portions 43 are pushed forward until the base portion 41 of the reinforcing plate 40 hits the partition wall 23 (see FIG. 5).

Subsequently, the pair of fixing portions 51 (pegs 50) are attached to the attachment portion 25 of the connector housing 20 (see FIG. 2). At this time, the connection auxiliary portion 52 connecting the pair of fixing portions 51 contacts the flexible cable 30 and bends the flexible cable 30 . Since the lower end portion 54 of the connection assisting portion 52 has a smoothly curved shape, the flexible cable 30 is less likely to be damaged even if the lower end portion 54 of the connection assisting portion 52 comes into contact with the flexible cable 30 .

When the pair of fixing portions 51 are attached to the connector housing 20, the body portion 31 of the flexible cable 30 is bent downward by the contact surface 53 of the connection auxiliary portion 52 (see FIG. 4). Also, the position of the flexible cable 30 is adjusted by the positioning portion 27 , the support portion 28 and the angle regulation portion 29 of the connector housing 20 . Finally, the board connection portion 35 of the other end portion 33 of the flexible cable 30 extends downward and rearward of the connector housing 20 .
Thus, the manufacture of the connector 10 is completed.

Then, the connector 10 is mounted on the circuit board 5. Solder paste is applied in advance to the fixed lands and connection lands of the circuit board 5 . When the connector 10 is placed on the circuit board 5 , the board connecting portion 35 of the other end 33 of the flexible cable 30 comes into contact with the circuit board 5 . The lower surface of the board connection portion 35 is in contact with the connection land, and the fixed portion 51 is in contact with the fixed land. By reflow, the conductive path 36 arranged on the board connection portion 35 and the connection land are soldered, and the fixed portion 51 and the fixed land are soldered. The flexible cable 30 (the plurality of terminal portions 43) and the circuit board 5 are electrically connected by soldering the conductive paths 36 and the connection lands. The connector housing 20 is fixed onto the circuit board 5 by soldering the fixing portion 51 and the fixing land. Thus, the manufacturing of the connector package 1 is completed.

Since the board connection part 35 is composed of the flexible cable 30, even if the circuit board 5 is deformed due to temperature changes during reflow, the board connection part 35 can be deformed following the surface of the circuit board 5. Therefore, connection reliability between the connector 10 and the circuit board 5 can be improved.

(2) In the above embodiment, the plurality of terminal portions 43 are composed of the one end portion 32 of the flexible cable 30 and the reinforcing plate 40. However, the present invention is not limited to this, and the plurality of terminal portions is composed of the plurality of terminal metal fittings. may be
(3) In the above embodiment, the directions in which the

connector housings

20 and 120 open are parallel to the surface of the circuit board 5. However, the present invention is not limited to this. may be perpendicular to the surface of the
(4) In the above embodiment, the lower ends 54 of the connection aids 52 and 152 were formed by bending the metal plate material into a substantially U shape, but the present invention is not limited to this, and the lower ends of the connection aids are formed at the lower ends of the connection aids. For example, a metal plate material may be bent into a substantially L shape.
(5) In the above embodiments, the plurality of terminal portions 43 are press-fitted into the through holes 26 of the

connector housings

20, 120 and held by the

connector housings

20, 120, but this is not the only option. For example, a configuration in which a locking portion is provided in the connector housing, a locking receiving portion is provided in the base portion of the reinforcing plate, and a plurality of terminal portions are held in the connector housing by locking between the locking portion and the locking receiving portion is employed. good too.
