摘要:
A system and approach that may connect communication modules together in a daisy chain fashion as an expansion bus. A communication module may be connected with a data bus and a voltage bus to a baseboard having a controller. The communication module may have a multi-port universal serial bus hub connected to the data bus from the expansion connector, an electronic device connected to the hub and the voltage regulator. Another communication module having a similar structure as the first communication module may be connected to the first communication module via a data bus between the multiport hub of the first expansion module and a universal serial bus hub of the other communication module, and may have a voltage bus connected to the voltage bus of the first communication module. More communication modules may be connected in a daisy chain or serial fashion to a preceding module, and so on in a similar manner.

The present invention relates to an interconnect structure for coupling an electronic unit (120) for outputting and/or receiving electric signals, and an optical unit (100) for converting said electric signals into optical signals and/or vice versa. The present invention also relates to an optoelectronic module comprising such an interconnect structure. The interconnect structure comprises an electrically insulating substrate and at least one pair of transmission leads (104, 106) to be coupled between said electronic unit (120) and said optical unit (100), a first lead (104) being operable as a signal line, a second lead (106) being operable as a ground line, wherein said second lead (106) is formed to have a lower impedance than said first lead (104). Cross-talk between neighbouring VCSEL is reduced as a signal current supplied by the signal line (104a) is mainly returned via the respective ground line (106a) and not via the signal line (104b) of the adjacent VCSEL. The ground lines (106) are connected to a ground plane layer (108) via contacts (118).

There is provided an electric junction box (1) which can reduce the usage of the heat-resistant resin for a connector fitting portion. The electrical junction box (1) includes a case (4) including a box-like body (3) and a box-like body (2) to be assembled together, a substrate (5) received in the case (4), a connector fitting portion (9) arranged to engage with a connector and having a terminal (6) soldered to the substrate (5) with lead-free solder, a holding portion (19) holding the terminal (6), and a tubular outer wall (8) surrounding the terminal (6). The holding portion (19) and the outer wall (8) are formed as separate parts. The outer wall (8) is divided into two segments formed integrally with the box-like bodies (3, 2), respectively. The holding portion (9) is made of heat-resistant resin while the outer wall (8) is made of non-heat-resistant resin.

A bused electrical center and a method for its construction. The bused electrical center includes a plurality of bus bars, which are housed between a bus bar housing and a filter housing, a filter device and a plurality of interface terminals that couple leads on the filter device to isolation tabs formed on the bus bars. No solder is employed to electrically or mechanically couple the interface terminals to the leads or to the isolation tabs such that the interface terminals are the sole means for electrically connecting the isolation tabs and the leads.

There is provided a junction box unit that comprises a body to which a power integration unit is attached and a connector cover that positions a connector of a wiring harness with respect to the body. The connector cover comprises a holding portion holding the connector, a mounting portion attached to the body, and a main body to be accommodated therein. The mounting portion comprises an engagement projection and an engagement arm. The engagement projection protrudes from one end of the main body for locking engagement with a locking portion of the junction box body. The engagement arm includes an arm main body having one end continuing to an outer surface of the other end of the main body and a free end. A protrusion is provided at the central portion of the arm main body for locking engagement with the locking portion. When the protrusion is in locking engagement with the locking portion, the other end of the arm main body is positioned more outwardly of the body than the locking portion.
