Zusammenfassung: | To facilitate radiation of heat of an IC incorporated in a connector.SOLUTION: A connector device 1 comprises a circuit board 10, and a connector 20 installed on the circuit board 10. The connector 20 has: an outer conductor 33 that can be conductive with a shield layer 91 of a shield wire 90; a sub substrate 35; an IC 36 mounted on the sub substrate 35; and a heat transfer part (a heat radiation sheet 61, a metal plate 60, the outer conductor 33, and a sub ground circuit 52) that propagates heat of the IC 36 to the shield layer 91. Due to this configuration, the heat of the IC 36 can be propagated to the shield layer 91 of the shield wire 90 via the heat transfer part, which can facilitate radiation of heat of the IC 36.SELECTED DRAWING: Figure 4
【課題】コネクタに内蔵されるICの熱を逃がしやすくする。【解決手段】コネクタ装置1は、回路基板10と、回路基板10に設置されるコネクタ20と、を備えている。コネクタ20は、シールド電線90のシールド層91と導通可能な外導体33と、サブ基板35と、サブ基板35に実装されるIC36と、IC36の熱をシールド層91に伝える伝熱部(放熱シート61、金属板60、外導体33、サブグランド回路52)と、を有している。この構成によれば、IC36の熱を、伝熱部を介してシールド電線90のシールド層91に伝えることができるため、IC36の熱を逃がしやすい。【選択図】図4 |
