COMMUNICATION REPEATOR APPARATUS BUILT IN FUNCTIONAL BLOCKS ON ONE BOARD

摘要

A communication relay apparatus in which functional blocks are integrally formed is provided to arrange each functional block on one substrate, thereby removing a connection wire and improving heat discharging performance. In a substrate(110), a functional block(a~g) performing each function of a communication relay apparatus is integrally mounted. A lower heat discharging plate(100) is adhered to a lower part of the substrate. The lower heat discharging plate performs a heat discharging function. In an upper heat discharging plate(200) is the top of the substrate. The upper heat discharging plate is combined with the lower heat discharging plate. Functional block insertion grooves(A~G) are formed at each location corresponding to the functional block in the upper heat discharging plate. In the upper heat discharging plate, an upper heat discharging fin(201) is formed in an opposite external side to a side contacting with the substrate.
