The abutting piece 65 is pushed downward during the insertion in which the abutting piece 65 is in contact with the insertion opening edge 63. However, when the abutting piece 65 is completely inserted, the abutting piece 65 is completely pulled out to the front side of the chassis. Rise to
Its tip is locked to the insertion opening edge 63, and the connector 64 is fixed to the chassis 61. After the connector 64 is fixed to the chassis 61 in this way, a jumper wire is soldered between the metal terminals 66, 66 of the connector 64 and the output portion of the printed board (not shown) in the chassis 61 by soldering or the like. Wiring connected.

However, in various kinds of recent electronic devices, connectors,
Since many electronic components such as an indicator lamp, an operation switch, and a fuse box are attached to the surface panel or chassis, the number of wiring work steps is increasing and the work itself is also complicated. Therefore, it is desired to simplify the wiring work to the electronic components attached to the front panel or chassis of the electronic device and reduce the man-hours for the wiring work.

In addition to the above, in the assembly of electronic devices, the work of assembling the printed circuit board is also increasing, and it is also desired to reduce the number of assembling steps of the printed circuit board.

[Object of the Invention]

In order to solve the above-mentioned problems, the present invention not only simplifies the wiring work between the electronic components mounted on the panel or the chassis and the printed wiring board and reduces the man-hours, but also reduces the man-hours for mounting the printed circuit board. An object is to provide a method of assembling an electronic device.

[Disclosure of Invention]

In order to achieve the above-mentioned object, a method for assembling an electronic device according to the present invention is a panel or a chassis for an electronic device,
An electronic component is assembled by attaching the electronic component, which is composed of a main body portion and a receiving portion that is separably locked to the main body portion, to the panel or chassis, and mounting the electronic component. In this case, a dividing line that enables separation into a plurality of sections is provided at a required position, and at least one of these sections is mounted with a main body of an electronic component attachable to the panel or chassis. At the same time, prepare a printed circuit board in which the main body section mounting section and at least one section of the other sections are connected by a jumper wire, and attach the electronic component receiving section to the panel or chassis. By separating the printed circuit board into a plurality of compartments and locking the main body of the electronic component mounted in the separated compartments to the receiving portion, Characterized in that so as to wear.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a printed circuit board used in an embodiment of the present invention, and FIG. 2 shows a state when electronic components are mounted using this printed circuit board. In order to be able to separate the printed circuit board into a plurality of sections 1a, 1b ... 1f, a large number of dividing lines 2 formed of slit-shaped through holes are provided in the printed circuit board body 1
It is provided in. Then, an electronic component that can be attached to another member such as a chassis or a panel is mounted on the printed circuit board body 1
Are mounted in each of the two sections 1c and 1d. Hereinafter, in this specification, "electronic parts" means electronic parts that can be attached to other members, such as connectors, display lamps, and operation switches. Here, two types of connectors are used as electronic components, and some of them, namely,
The connector main body 3 provided with the pin contacts 3a, 3a and the connector main body 4 provided with the socket contacts 4a, 4a are provided in the sections 1c and 1d of the printed circuit board body 1, respectively.
It is implemented. The section 1c and the section 1d are electrically connected to each other by jumper wires 5a and 5a.
d is further divided into sections 1 by jumper wires 5b and 5b.
It is electrically connected to a. Then, the tips of these jumper wires 5a and 5b, the lower ends of the pin contacts 3a and 3a, and the lower ends of the socket contacts 4a and 4a are soldered so as to have a desired wiring relationship on the back surface side of the substrate. ing.
Although not shown, of course, other passive elements such as resistors, capacitors, and coils, and active elements such as transistors and ICs are mounted on the printed circuit board body 1 as required. Normally all soldering is done at the same time.

The printed circuit board used in the present invention on which the electronic components are mounted is used as follows. When the joining between the dividing lines 2 is broken (knockout), the sections 1a, 1b, ... 1f are cut and separated from each other. Then, as shown in FIG. 2, the partition 1c having the connector body 3 and the partition 1d having the connector body 4 are wired with jumper wires 5a, 5a between them, and the partition 1d And the section 1a between the jumper wire 5b,
The wiring is separated by 5b.

On the other hand, a connector receiving portion is attached to the chassis 8 in advance. As shown in FIG. 5, the connector receiving portion 3 ′ is held by the chassis 8 with a part of the wall of the chassis 8 bit between the four contact claws 3 e and the front plate edge 3 f. When the connector body 3 is pushed into the connector receiving portion 3 ', the projection 3d of the connector body 3 engages with the locking hole 3h of the locking piece 3g, and the connector body 3 is locked to the connector receiving portion 3'. . Then, the connector body 3 is attached to the chassis 8 via the connector receiving portion 3 '. The connector receiving portion 4'and the connector body 4 are also
It is attached to the chassis 8 in the same manner. In this way
When the connector bodies 3 and 4 are attached to the chassis 8, all wiring between the printed board 1a and the connector bodies 3 and 4 is completed.

In this way, at the same time when electronic components are attached to other members,
Since the wiring between the electronic components and the wiring with the printed circuit board are completed, the wiring work at the time of assembly can be simplified and the number of steps can be reduced. Furthermore, instead of the conventional wiring work such as soldering to complicated places in the chassis, it is called a printed circuit board.
In other words, since the wiring work is performed at a part of the flat member, there are few erroneous wirings, and therefore, the yield of products is increased. Further, since the soldering work may be performed at the same time as the soldering of the entire printed circuit board, the efficiency can be improved also in this respect.

The hole 1'of the section 1a of the printed circuit board is used as a space for mounting other members. When the device in which the chassis 8 is used is, for example, an audio amplifier unit, the connector body 3 including the pin contactor 3a
Is used as a signal input terminal (inlet) from the player section, and the connector body provided with the socket contactor 4a is used as a signal output terminal (outlet) to the speaker section 4.

Next, another embodiment of the method for assembling the electronic device of the present invention will be described with reference to FIGS. 3 and 4. FIGS. 3 and 4 show a printed circuit board used in another embodiment of the method for assembling electronic equipment of the present invention. In the printed circuit board of FIG. 3, the connector body 3 is mounted in the section 1g, and the connector body 4 is mounted in the section 1h. The section 1g and the section 1h are connected by a jumper wire 5d.
It is connected to i and the section 1j by jumper wires 5c and 5c. In this way, if wiring is performed from one section to several sections and then each section is separated and each section is attached, even considerably complicated wiring can be completed at once.

In FIG. 4, a plurality of different electronic components of one connector main body 3 and two connector main bodies 4 are shown in the section 1
It is implemented in t. After being separated from the printed circuit board body 1, these connector bodies 3 and 4 on the compartment 1t are fitted into the respective receiving portions provided on the chassis at one time, and a large number of electronic components are mounted and necessary. Wiring is completed at the same time. Of course, the shape of the electronic component is selected and the mounting position of the printed circuit board 1 to the partition 1t is adjusted so that there is no displacement between the electronic component and the receiving portion when fitting.

In the example of FIG. 4, different types of connectors were attached, but further, a switch and a fuse box were simultaneously mounted, the connector was fitted into the receiving portion, and the switch and the fuse box were attached from the front side of the chassis. If the nuts are tightened in the stop holes provided in the chassis, wiring efficiency will be further improved.

〔The invention's effect〕

Since the present invention has the above configuration, the following effect (1),
(2) can be achieved, and its usefulness is extremely remarkable.

Effect (1) The wiring work between the electronic component mounted on the panel or the chassis and the printed wiring board can be simplified and the number of steps can be reduced.

This is because the compartment where the main body of the electronic component to be mounted on the panel or chassis is mounted and other compartments are connected by jumper wires, and the wiring required before assembly is practically complete, and the separation of the printed circuit board This is because wiring is completed by mounting the electronic component. The jumper wire connection itself is not the soldering work on the complicated parts inside the chassis as in the past, but the wiring work in the so-called flat state of the printed circuit board is the center, so there are few miswirings etc. The rate of non-defective products is also improved.

Effect (2) The number of steps for assembling the printed circuit board can be reduced.

This is because the assembly of the separated plaint board, which is the section in which the main body of the electronic component is mounted, is completed simply by locking the main body of the electronic component in the receiving portion. That is, the electronic component itself has a function of easily attaching the separated printed circuit board by locking the receiving portion and the main body portion. Even when mounting the main body of the electronic component on the printed circuit board, the mounting work at the printed circuit board in a so-called planar state is the center, and therefore the mounting can be performed easily and quickly.
