CONNECTOR ASSEMBLY

摘要

Disclosed is a connector assembly (1) which comprises a connector (10), a cable (20), a wiring board (30) and an insulating material (40). First connection parts (32) of the wiring board (30) electrically connect contact terminals (11) of the connector (10) and wiring lines (34). Second connection parts (33) of the wiring board (30) electrically connect conductors (221) of the cable (20) and the wiring lines (34). The pitch (P1) of the first connection parts (32) and the pitch (P2) of the second connection parts (33) are in the relation of P1 < P2. The dielectric constant (E1) of the insulating material (40) surrounding the first connection parts (32) and the dielectric constant (E2) of the insulating material (40) surrounding the second connection parts (33) are in the relation of E1 < E2. Consequently, when the conductors (221) are connected with the second connection parts (33), the conductors (221) can be prevented from being short circuited with each other and the impedance of the first connection parts (32) and the impedance of the second connection parts (33) can be matched.
