Some of the above-mentioned circuit components of electronic equipment do not use automatic mounting and reflow soldering, and have leads having electrode shapes that cannot be used for surface mounting. Lead components are used, and the lead components are placed on a printed circuit board and soldered manually. For this reason, there is a possibility that electrical connection failure may occur when mounting the lead component on the printed circuit board, and there is a problem that reliability is lacking.

[0004] An object of the present invention is to provide a surface mount connector which does not have a risk of causing electrical connection failure when mounting lead components on a printed circuit board and which does not lack reliability in order to eliminate such conventional disadvantages. Is to do.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the surface mount connector of the present invention.

The present embodiment shown in FIG.
When a plurality of leads 7 (hereinafter, referred to as, for example, two leads 7) are respectively inserted, a plurality of contact portions 2 (hereinafter, referred to as two leads 7) that respectively contact the two leads 7 and hold the two leads 7 respectively. For example, two contact portions 2 are described.) And a plurality of contact portions 2 that are respectively connected to the two contact portions 2 so as to abut on the surface of the printed board 9 when the surface mount connector 1 is mounted on the printed board 9. (Hereinafter, referred to as, for example, two electrodes 3), and a main body 4 including the two contact portions 2 and the two electrodes 3.

Next, the surface mount connector of the present embodiment will be described with reference to FIGS.

FIG. 2 is an XY sectional view of the present embodiment shown in FIG.
Each of the electrodes 3 is connected to each other, and each of the electrodes 3 extends to a lower portion of the main body 4.

FIG. 3 is a cross-sectional view of the embodiment shown in FIG. 1 when lead components are mounted and mounted on a printed circuit board.
The pattern 10 of the printed circuit board 9 and the electrode 3 of the surface mount connector 1 are soldered with solder 8 such as cream solder, for example, and the lead 7 of the lead component 6 is inserted into the surface mount connector 1. The lead 7 is connected to the contact portion 2 by the spring pressure of the spring 5 of the contact portion 2.
3 shows a state in which it is in contact with and held. At this time, the lead 7 of the lead component 6 is inserted perpendicularly to the surface of the printed circuit board 9. In addition, this surface mount connector 1
Is mounted on a printed board 9 on which solder 8 such as cream solder is printed by an automatic mounting machine or the like, and is passed through a reflow furnace or the like, and is soldered to the printed board 9.

In FIG. 1, each contact portion 2 of the two contact portions 2 provided in the main body 4 has a spring 5 as shown in FIG. 2, and has, for example, two leads 7 as shown in FIG. When each lead 7 of the lead component 6 is inserted into each of the contact portions 2, the lead 7 comes into contact with the inserted lead 7 by the pressure of the spring 5 and holds the lead 7. The respective electrodes 3 of the two electrodes 3 provided on the main body 4 are connected to the two contact portions 2 respectively, and extend to the lower part of the main body 4 as shown in FIG. These electrodes 3 are soldered to a printed circuit board 9 as shown in FIG.

In the above description, the surface mount connector 1 formed so that the lead 7 of the lead component 6 is inserted perpendicular to the surface of the printed circuit board 9 has been described. However, as shown in FIG. May be provided parallel to the surface of the printed circuit board 9, the contact portion 2 of the surface mount connector 1 may be provided on the side surface of the main body 4.

[0015]

As described above, according to the surface mount connector of the present invention, a plurality of contact portions which come into contact with and hold the plurality of leads of the lead component, respectively, and are respectively connected to the plurality of contact portions. Since it has a plurality of electrodes each of which comes into contact with the surface of the printed circuit board, and a main body having a plurality of contact portions and a plurality of electrodes, the surface mount connector can be attached to the printed circuit board by, for example, an automatic mounting machine. After mounting and passing through a reflow furnace, the lead components can be mounted on the printed circuit board without manual soldering by mounting the lead components on this surface mount connector. Lead components can be mounted on flexible printed circuit boards.
