Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a method for connecting electric circuits, which allows, for example, two printed circuit boards to be connected relatively easily.

Figure 1 shows an example of a conventional electrical circuit connection method, in which a pin 2 is implanted in a first connected object 1 such as a printed circuit board, and a pin 2 is embedded in a second connected object 3 such as a printed circuit board. Insert the pin 4 and connect the bare wires 6 and 7 at both ends of the jumper wire 5 to the pin 2,
4, and then soldered.

This connection method involves winding the bare wires 6, 7 around the pins 2, 4, which requires manual labor and is extremely difficult to mechanize.

Therefore, the present invention aims to provide a method for connecting electrical parts that is relatively easy to mechanize, and one embodiment of the present invention will be described below with reference to the drawings.

A connecting body 8 made of an insulator as shown in FIG.
At least one groove 9 is provided in the groove 9, and through holes 10a and 10b are formed at both ends of the groove 9.

10a in FIG. 3 indicates one of the through holes.

On the other hand, as shown in FIG. 4, at least one conductive pin 12a connected to the electrical circuit of the first connected object 11a, such as a printed circuit board, is planted upward. , a conductive pin 12b connected to a second connected object 11b such as a printed circuit board, and the electrical circuit E of this connected object 11b.
Plant at least one tree facing upward.

This pair of pins 12a. 12b to the through hole 10 of the connecting body 8,
10b from below, and position the pins 12a and 12b in the groove 9.

In this state, by pouring molten solder 13 into the groove 9 and then solidifying the solder, the objects to be connected 11a and 11b can be electrically connected.

If a plating layer is provided on the inner wall of the groove 9 of the connecting body 8, the solder 1
3 is securely fixed in the groove 9, and there is no need for solidified solder to come out from the groove 9.

For the plating layer, grooves 9 are provided as shown in FIGS. 5a, b, and c, and then a plating layer 14 is provided on the entire surface of the connecting body 8, and only the plating layer on the upper surface is removed.

The connected objects 11a and 11b may be a printed circuit board, a metallic chassis, a tuner, a flyback transformer, or other components.

However, the connected object 11a. Pin 12a provided on 11b,
It is better if the connectors 12b are on the same plane in terms of attaching the connecting body 8 and pouring the solder, but the connecting body 8 may also be attached at an angle.In this case, it is better to pour the solder from the higher side. good.

The above connection method connects the connecting body 8 to the attached bodies 11a, l.
Mechanizing the work of attaching to the lb and applying solder to the groove 9
It is easier to mechanize the inner pouring operation than to mechanize the winding operation shown in FIG. 1, and it is useful as a method for connecting a pair of objects to be attached.

For example, take a television receiver as an example (all the mounting and soldering of parts to the printed circuit board are mechanized, and the only manual work left is connecting the printed circuit boards with jumper wires, etc.). If this method were mechanized, it would be possible to manufacture television receivers with almost no manual labor involved.

As described above, according to the present invention, two connected objects are connected electrically.
This can be connected relatively easily.
