DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire connector in which a large number can be arranged on a printed circuit board at a high density without deteriorating the insertability of electric wires.

[0002]

2. Description of the Related Art As an electric wire connector mounted on a printed circuit board, the one shown in FIG. 6 is conventionally known. The electric wire connector 1 is configured by mounting a conductive plate 3 formed of a copper alloy thin plate in a main body 2 formed of an insulating synthetic resin in a substantially box shape. An electric wire insertion portion 5 having an electric wire insertion hole into which the electric wire 4 is inserted from above is provided on an upper portion of the main body 2, and a quick connection terminal formed by bending the conductive plate 3 faces the electric wire insertion hole. In addition, a part of the conductive plate 3 is protruded downward from the lower surface of the main body 2 as the terminal part 6, and this terminal part 6 is inserted into a terminal insertion hole provided in the printed circuit board 7 and connected by soldering.

In this electric wire connector 1, as shown in FIG. 7, the projected area of the electric wire connector 1 itself on the printed circuit board 7 can be reduced, and a large number of the electric wire connectors 1 can be arranged on the printed circuit board 7 at high density. Easy to insert.

[0004] However, as shown in FIG.
There is a problem that the height is increased not only the height of the wire itself but also a margin for drawing out the electric wire 4.

To reduce the height, an electric wire connector 1 as shown in FIG. 9 is also known. In the electric wire connector 1, an electric wire insertion portion 5 is provided on a side of the main body 2 so that the electric wire 4 can be inserted from a direction along the printed circuit board 7.

If a large number of the electric wire connectors 1 are to be arranged side by side, they can be arranged at a high density in a direction perpendicular to the drawing direction of the electric wires 4. However, in the drawing direction of the electric wire 4,
As shown in FIG. 10, it is difficult to insert the electric wire 4 unless the distance between the electric wire connectors 1 is widened to some extent, and if the distance is too large, the size of the printed circuit board is increased. There is a problem that the part 5 is close to the printed circuit board 7 and it is difficult to insert the electric wire 4.

FIG. 11 shows an electric wire connector 1 which solves the problems of the above two conventional examples. In the electric wire connector 1, an electric wire insertion hole 8 opened obliquely upward to guide and hold an electric wire in a quick connection terminal structure.
Is provided on the main body 1 to reduce the height so that the electric wire 4 can be inserted obliquely from above.

In the electric wire connector 1, the side surface 9 of the main body 2 on the electric wire insertion hole 8 side is formed so as to rise substantially vertically from the surface of the printed circuit board 7 to the lower end of the electric wire insertion hole 8. The side surface 10 opposite to the side surface 9 is formed slightly lower than the side surface 9, and the upper surface of the main body 2 is inclined substantially along the inclination of the wire insertion hole 8. Therefore, when the two electric wire connectors 1 and 1 are adjacent to each other, as shown in FIG. 12, the side surface 9 of the one electric wire connector 1 on the side of the electric wire insertion hole 8 and the electric wire insertion hole 8 of the other electric wire connector 1 Side 10 opposite to
Can be substantially adhered to each other. Then, a large number of electric wire connectors 1 can be arranged close to each other and attached to the printed circuit board 7 at a relatively high density, and the insertability of the electric wire 4 does not easily deteriorate.

However, in the electric wire connectors shown in FIGS. 11 and 12, it is not particularly intended to arrange a large number of them at high density, so that the structure of the electric wire connector 1 itself has not yet been sufficiently considered. It was hard to say that it had been densified.

[0010]

SUMMARY OF THE INVENTION An object of the present invention is to realize an electric wire connector which can be arranged adjacently at a high density without increasing the height of the electric wire connector.

An electric wire insertion hole 19 is formed in the conductive plate 3 from the connecting portion 17 to the electric wire contact portion 16. The quick-connecting spring portion 18 is formed such that the distal end thereof has a space slightly smaller than the diameter of the electric wire 4 between itself and the electric wire contact portion 16. A guide portion 20 is provided on a side edge near the distal end of the quick-connecting spring portion 18 to prevent the electric wire 4 from coming off from the electric wire contact portion 16 when the electric wire 4 is inserted.

The terminal portion 6 of the conductive plate 3 has a body 2 near the tip.
The terminal 6 is inserted downward into a terminal insertion hole 13 provided in the printed circuit board 7 and connected by soldering to establish conduction between the printed circuit board 7 and the conductive plate 3.
