Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved printed circuit board mounting device, and in particular, it is an object of the present invention to provide a printed circuit board mounting device that facilitates wiring work.

For printed circuit boards with wrapper pins, the work of connecting the wrapper pins and external lead wires must be done after the printed circuit board is attached and fixed to the chassis of the audio equipment, so the print should be made so that the head of the wrapper pin is on the upper side. The board must be attached to the chassis or the like. However, depending on the condition of the parts placed on the printed circuit board, or depending on the space available when fixing the printed circuit board and the chassis, the printed circuit board may be placed so that the printed surface of the printed circuit board faces upward. In some cases, it may be necessary to install the rappel pin, and in such cases, the head of the rappel pin will be on the lower side, so
This has the disadvantage that the work of connecting the wrapper pin and the lead wire becomes extremely difficult.

The present invention has been developed in view of the above points, and will be described below based on embodiments and with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a printed circuit board mounting device according to the present invention, and 1 has printed wiring on the back side and electrical components 2, 3, and 4 mounted thereon as shown in FIG. A printed circuit board comprising a main body part 5 on which the wrapper pins 6a, 6b, 6c, and 6d are arranged, a wrapper part 7 on which the wrapper pins 6a, 6b, 6c, and 6d are arranged, and a separating part 8 for making the main body part 5 and the wrapper part 7 separable.
9a, 9b, 9c, 9d are printed terminals 10a, 10 arranged on the main body 5 of the printed circuit board 1.
b, 10c, 10d, and printed terminals 11a, 11b, 11c, 1 arranged on the wrapper part 7.
This is a lead wire that connects 1d. The separation section 8 is composed of perforations, V-shaped grooves, etc., and is arranged so that the main body section 5 and the wrapper section 7 of the printed circuit board 1 can be separated without using tools. has been done. Further, the lead wires 9a, 9b, 9c, 9d are connected to the printed terminals 10a, 10b, 10c, 10d of the main body part 5 and the printed terminals 11a, 11b, 11 of the wrapper part 7.
The length thereof is set to a predetermined value and is arranged so as to straddle the wrapper pins 6a, 6b, 6c, and 6d. In addition, as the lead wire, the first
As shown in the figure, each lead wire may be independent, or a tape jamb wire (eg, PC Joyner, trade name) may be used in which a plurality of lead wires are integrally molded. Also, printed terminals 12a, 12b, 1
2c, 12d are wrapper pins 6a, 6b, 6
It is for c, 6d. Next, during the assembly process,
explain. In the assembly process, first, the electrical components 2, 3, and 4 are attached to predetermined positions on the main body part 5 of the printed circuit board 1 , which has predetermined printed wiring on the back side, and the wrapper pins 6a, 6b, and 6 are attached to the wrapper part 7.
c, 6d, and lead wires 9a, 9 at predetermined positions between the main body part 5 and the wrapper part 7.
Attach terminals b, 9c, and 9d. Thereafter, when the printed circuit board 1 is subjected to a soldering process, the electrical components, wrapper pins, and lead wires are firmly fixed to the printed circuit board. The printed circuit board 1 that has been soldered is separated at the separating section 8 and becomes two parts. However, since the two parts are connected by the lead wires 9a, 9b, 9c, and 9d, there is no chance of one being lost. The printed circuit board 1 separated into two parts has the printed terminals 11a, 11b, 11c, and 11d of the wrapper portion 7 connected to the printed terminals 12a, 12b, and 12c on which the wrapper pins 6a, 6b, 6c, and 6d are respectively planted. , 12d, the printed terminals 10a, 10b, 1 of the main body 5
It is fixed to the chassis of the audio equipment so as to be close to 0c and 10d. That is, the main body part 5 and the wrapper part 7 are fixed to a chassis as shown in FIG. 3, and in the figure, 13 is the chassis and 14
Reference numeral 15 indicates an electrical component such as a volume fixed to the chassis 13, 15 indicates a main body portion of a printed circuit board to which the electrical component 14 is fixed, and 16 indicates an auxiliary fixing portion 18 connected to the main body portion 15 by a lead wire 17. A wrapper portion of the printed circuit board is fixed to the chassis 13 by screws 19, a wrapper pin 20 is soldered to the wrapper portion 16, and an external lead wire 21 is connected to the wrapper pin 20.

Therefore, the main body 15 of the printed circuit board is placed so that the printed wiring surface is on the upper side, and the electrical components 14 are
By fixing and the chassis 13, it is indirectly fixed to the chassis 13. Further, the wrapper portion 16 of the printed circuit board is attached to the chassis 13 by an auxiliary fixing portion 18 with screws 19 so that the printed wiring surface faces downward. Then, the lead wire 17 is connected to the first
As explained based on the diagram, straddle the trussper pin,
Since the lead wire 17 is connected between the portion of the main body near the separation portion of the printed wiring and the portion of the wrapper portion far from the separation portion, the lead wire 17 will not be twisted. Further, since the printed wiring surface of the main body portion 15 is oriented in the opposite direction to the chassis, accidents such as short circuits can be prevented. Furthermore, a wrapper pin 20 planted in the wrapper portion 16
Since the head thereof faces upward, the connection between the wrapper pin 20 and the external lead wire 21 can be easily performed.

As described above, the printed circuit board mounting apparatus according to the present invention is practical and has various advantages.
