Thin type cable modem and stand for mounting the same

Abstract

A high reliability cable modem is provided, which is superior in assembling workability, heat radiation, mounting stability. The cable modem includes a circuit board 10 which is a substantially single board on which a front end section 11, a logic circuit section 12 and an LED display section 13 are mounted; and a housing which covers the circuit board 10 and which has a front face 2, a rear face 8, a left side face, a right side face, a top face 4 and a bottom face 6. The cable modem is provided with a plurality of symbol display 3 for indicating an operational state of the LED display section 13 in the front face 2 of the housing 1, a plurality of exhaust holes 5 for radiating heat generated from the front end section 11 and the logic circuit section 12 mounted on the circuit board 10 in the top face 4 of the housing 1, and a plurality of inlet holes 7 for taking outside air into an interior of the housing 1 in the bottom face 6 of the housing 1. The front section 11 is mounted on the circuit board 10 at a position near the exhaust holes 5.

Description

technical field [0001] The present invention relates to a cable modem used as an interface for connecting a CATV (Cable TV) line and a personal computer, and a bracket for mounting the cable modem thereon. Background technique [0002] In recent years, cable modems have played an important role as an interface for high-speed data communications between CATV lines and home or business equipment. This cable modem is equipped with an interface function that converts coded transmission information into a reception signal for a personal computer. Figure 10 A schematic diagram showing a background art example of a cable modem system. In this system, Internet 101, personal computer communication 102 or various information 103 are transmitted through servers 201, 202 or through server 203 instead of CATV stations (for example, servers provided within the company), and are forwarded by router 204, and Further, the information is encoded by the cable modem e...

AI Technical Summary

Problems solved by technology

[0004] Such a cable modem, as shown above, takes a lot of time in assembly and inevitably increases the external dimensions of the case, takes up a considerable amount of space when mounted on a desk, and in addition the cable modem is very expensive in terms of unit weight. heavy, making it difficult to carry

Also, when a cable modem, which is normally placed horizontally, is placed vertically to save space, it is not stable because it tends to tilt

Moreover, there is another problem that when the cable modem has a small size and a thin design, due to an increase in the internal temperature of the housing, the operating environment temperature of the circuit parts will exceed the limit, thereby causing malfunction.
