Abstract

A method of forming a printed circuit board having a connector including providing a base portion including through holes into which terminals are inserted; inserting terminals projecting from a bottom surface of the base portion into a terminal hole provided on the printed circuit board; fitting a rib projecting from the bottom surface of the base portion with a through hole provided on the printed circuit board; temporarily fixing the bottom surface of the base portion, the surface contacting a surface of the printed circuit board; then fixing with soldering each of the terminals inserted into the terminal hole of the printed circuit board; fitting a connector housing with the base portion, the connector housing having a fitting hole within which the base portion is fitted; and placing the connector housing on the printed circuit board while the terminals are housed within the connector housing.

Claims

1. A method of forming a printed circuit board having a connector comprising:

providing a base portion including terminals projecting therefrom;

inserting each of the terminals projecting from the base portion into a respective terminal aperture provided on the printed circuit board;

fitting a rib projecting from the bottom surface of the base portion with an aperture provided on the printed circuit board;

temporarily fixing the bottom surface of the base portion, the bottom surface contacting a surface of the printed circuit board;

fixing with soldering each of the terminals inserted into the terminal apertures of the printed circuit board;

fitting a connector housing with the base portion, the connector housing having a fitting hole within which the base portion is fitted; and

placing the connector housing on the printed circuit board while the terminals are housed within the connector housing.

2. The method of forming a printed circuit board according to claim 1, said providing a base portion including terminals projecting therefrom further comprising:

providing holes in the base portion; and

inserting the terminals in the holes.

3. The method of forming a printed circuit board according to claim 1, said providing a base portion including terminals projecting therefrom further comprising:

insert molding a base portion with the terminals projecting therefrom.

4. The method of forming a printed circuit board according to claim 1, further comprising:

providing the printed circuit board with a plurality of base portions and the connector housing, the base portions aligned and including spaces therebetween;

providing the connector housing with through holes into which the base portions are fitted, the through holes including spaces therebetween; and

providing the connector housing with a dividing wall forming connector receptacles into which distinct connectors are fitted.

5. An electric junction box for a vehicle, comprising:

a printed circuit board having a connector, the printed circuit board housed within a case including a lower case and an upper case, the connector of the printed circuit board positioned on an outer surface of the case to fit with a connector connected to a wire harness;

the printed circuit board comprising;

a base portion including a plurality of terminals fixed therein, each terminal soldered through a respective terminal aperture in the printed circuit board and projecting therefrom;

a connector housing provided on a surface of the printed circuit board, the connector housing including a fitting hole therein, the base portion fitted in the fitting hole, and a rib provided on a surface of the base portion fitted into an aperture in the printed circuit board; and

a latching portion projecting from an outer surface of the connector housing that latches with latched portions provided on the lower case and the upper case, so that the connector housing is fixed between the lower case and the upper case.

6. The electric junction box for a vehicle according to claim 5, wherein the printed circuit board is formed by a method comprising:

providing a base portion including terminals projecting therefrom;

inserting each of the terminals projecting from the base portion into a terminal aperture provided on the printed circuit board;

fitting a rib projecting from the bottom surface of the base portion with an aperture provided on the printed circuit board;

temporarily fixing the bottom surface of the base portion, the bottom surface contacting a surface of the printed circuit board;

fixing with soldering each of the terminals inserted into the terminal apertures of the printed circuit board;

fitting a connector housing with the base portion, the connector housing having a fitting hole within which the base portion is fitted; and
