Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a mold 7 frame used for electronic equipment, etc., in which a conductor is embedded, and the layered conductor is used as wiring inside the equipment. Layout of an electric circuit with a body temperature wiring structure Im! Place it on the device.

[Conventional technology]

In conventional electronic devices, connections between electrical circuits (e.g. printed circuit boards) arranged in various parts of the device body are generally made using insulated lead wires. For example, the connection structure of
It is disclosed in the publication No.

[Problem to be solved by the invention]

As mentioned above, when the connection between the electric circuits (printed board M) is made using lead wires, for example, as shown in FIG.
7 frames made of glass! The electrical circuits on the printed circuit boards 22 and 23 arranged on the board 1 are connected to each other via the connector 24, etc. It is electrically connected by I (insulated conductive wire) 25.

In this case, as shown in the figure, in addition to the connection work between the lead wire 2s and the printed circuit board 22, 250, a predetermined portion of the lead wire 25 is fixed along the inner wall surface of the 7th frame 21 with a fixture 24. This is because it is necessary to bind the plurality of 0-lead bundles 25 together with a band or the like, and it is also required to thread the lead wires 25 through a narrow gap within the 7-frame 21.

There was a problem in that the overall connection workability was poor. In addition, the need to secure space for the lead wires 25 within the frame 21 so as not to interfere with other components is one of the factors that impairs the degree of freedom in arranging printed circuit boards and mechanical components. It was becoming.

The purpose of the present invention is to solve the problems of the above-mentioned prior art, to improve the workability of connecting electrical circuits within the equipment body, to obtain a wiring structure with good space 7 attachment, and to make the equipment into a shed. The object of the present invention is to provide an electric circuit O wiring device that can contribute to

[Rounding method to solve the problem]

In order to achieve the above-mentioned object, the present invention includes a 7-wire 5 made of plastic with insulating properties, and a conductor for relaying and connecting separate electric circuits inserted and disposed therein by insert molding. A wiring structure of one frame and one Mi is adopted.

[Effect]

Conductive wire for use as wiring inside the device is placed on the plastic frame that holds various circuit systems and mechanical components such as printed circuit boards installed inside the main body of the electronic device, or the main frame of the device. The body (conductive wire or conductive thin plate) is embedded in the frame in advance by insert molding. This conductor is exposed from, for example, the 7th frame in its image direction, and is connected to the printed circuit board held at the 7th frame through, for example, a connector at this exposed portion. With such a frame-integrated wiring structure, there is no need to route the lead wires through narrow gaps in the 5 device bodies (7 frames), and the lead wires can be easily connected to each other while fixing the lead wires at specified locations. Since there is no need for binding work, assembly work efficiency is improved. Also, make sure you have enough space to route the lead wires! Since there are no parts, there is a high degree of freedom in arranging components within the device, which also contributes to miniaturization of the entire device. Furthermore, compared to the lead III connection, the external connection has improved workability and is suitable for mass production, making it possible to lower the cost.

〔Example〕

The present invention will be explained below with reference to an embodiment shown in FIGS.

FIG. 5 is an enlarged sectional view of the main part of FIG. 1. .

In the figure, 1 is an insulating plastic frame that is molded into a predetermined shape using an insulating mold.It forms the main frame of the equipment O and also supports various components. ing. 2 is a conductive wire, for example, made of Cu, placed on the 7th frame 1, which is inserted into a predetermined position KI (embedded and disposed>) by an insert mold during molding of the 7th frame 1, and its both ends are for connecting the 7th frame 1. Projection 1m
It is made to be exposed in. Incidentally, the conductive wire 2 may be replaced by a thin strip made of a highly conductive metal thin plate. In addition, the 7-frame 1 should preferably be made of a material with excellent flammability and high insulation reliability, but if it is made of general grade glass, there will be no practical problem, so it is important to be particular about the material used in 41. It's not a thing.

Reference numeral 5 denotes a rattan 20 printed circuit board which is similarly held on the seven frames 1 through appropriate means, and this second printed circuit board 5 is equipped with, for example, a control circuit for the motor drive circuit described above.

6.6 is the above N1. As shown in Fig. 5, the conductor piece 6b in the connector housing 6 of the connector 6 is connected to the conductor at the connection protrusion 1a. The motor drive circuit on the #11 printed circuit board 5 and the control circuit on the second printed circuit board 5 are connected to the conductive wire 2 embedded in the 7th frame 1. They are electrically connected by line 2.

In this embodiment having such a configuration, the connection between the second printed circuit boards 5 and 5 is $1.

Assembly work is improved because there is no need to sew the lead wire through a narrow gap in the frame 1 as in the past, or to fix the lead wire at a predetermined part to the frame 1. It is also advantageous in terms of cost because it improves mass productivity and is suitable for mass production. In addition, there is no need to secure a space for routing lead wires, so there is a high degree of freedom in arranging components within the device.t) 1) It can also contribute to making the entire device a shed.
