Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply path structure for an electronic device.

Conventionally, the power supply path structure of electronic devices such as communication equipment is
In the connection structure of the power supply path with the outside, it was common to connect the external interface wire directly to the back wiring board. In this case, the electronic circuit package is attached and detached from the front of the device, and the power supply line is connected from the back of the device. Therefore, work such as rack mounting, maintenance, and inspection must be performed on both the front and rear sides of the equipment, resulting in poor work efficiency.In addition, it is necessary to provide maintenance space for the electronic equipment on both the front and rear sides of the equipment. It was also difficult to reduce the space.

This invention is a power supply line structure for electronic devices that has a relatively large housing such as a communication device, and improves the workability of rack mounting, maintenance, and inspection, and also reduces the installation space. The purpose is to provide

In order to achieve the above object, the present invention provides an electronic device in which a plurality of electronic circuit packages are connected to one back wiring board with a connector, which is in contact with a power supply pattern formed on the back wiring board and has a screw. a clamp having a section, and a first threaded section having approximately the same length as the electronic circuit package at one end to be screwed into the threaded section provided in the clamp, and at the other end for connecting a power supply lead of a power supply path. a conductor rod formed with a second threaded portion, the conductor rod is inserted from the same direction as the insertion direction of the electronic circuit package, and the first threaded portion is inserted into the clamp attached to the back wiring board. The present invention is characterized in that the second threaded part is screwed onto the threaded part, and the second threaded part for connecting the power supply lead of the conductor rod is exposed on the same surface as the insertion surface of the electronic circuit package.

The drawing shows an embodiment of the power supply path structure of an electronic device according to the present invention, and in the drawing, 1 indicates a shelf;
A plurality of electronic circuit packages 2 housed inside the shelf 1 are connected to a back wiring board 4 via connectors 3.

A printed wiring 5 is formed on the back wiring board 4, which is bent into a hairpin shape to be in contact with the printed wiring 5, and a clamp 6 having a through hole 15 on one side and a female screw 14 on the other side is inserted. Reference numeral 9 denotes a conductor rod, which has approximately the same length as the electronic circuit package 2 and has a male screw 7 protruding from one end thereof to be screwed into the female screw 14 of the clamp 6, and a female screw 8 from the other end.
A groove 11 for driver operation is formed. Although the conductor rod 9 in the illustrated embodiment is made of aluminum, it goes without saying that other conductive materials may be used.
The electronic circuit package 2 is then screwed through the hole in the back wiring board 4 to the female screw 14 on one side of the clamp using the driver operation groove 11, and the other end is inserted into the through hole 10 which is insulated on the front surface of the shield 1. Attach it parallel to the Thus the conductor rod 9
Since the female screw 8 and the driver operating groove 11 protrude to the front, the power supply lead 12 that connects to the outside connects the mounting piece 12' at the end of the power supply lead 12 to the female screw 8 of the conductor rod 9.
It is connected by screws 16. The signal connection with the outside is performed by a signal line connector 13 provided on the front side of the electronic circuit package 2.

Since the present invention has the above-described configuration, all work such as mounting the rack on the electronic device, maintenance, and inspection can be performed only from the front of the device, and the conductor rod can have a sufficient cross-sectional area. As a result, low voltage and large capacity power supply is possible, the above-described drawbacks of the conventional power supply path structure are eliminated, and the practical value is increased.
