Abstract

Abstract A multiplexed wiring system for use with a vehicle having a centralized control system in which various electrical devices located at different portions of a vehicle are centrally controlled by a central processing unit through control or driver circuit elements respectively associated with corresponding electrical devices. The wiring system comprises a main cable (56) including a signal transmission path (56S) for transmission of signals to be sent from or to be applied to the central processing unit (52) and a power transmission path (56P) for transmission of power to be fed from a power source (50), and a connector provided for each of groups (60A, 60B, ... 60J) of the electrical devices, each group including those electrical devices which are relatively in close to each other, the connector having therein an integrated terminal controller (54A, 54B, ... 54J) having the control or driver circuit elements associated with corresponding electrical devices, connecting means (18) for connection of the therminal controller to the main cable, and connecting means (10) for connection of the terminal controller to the corresponding electrical devices.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 204 words
A multiplexed wiring system for use with a vehicle having a centralized control system in which various electrical devices located at different portions of a vehicle are centrally controlled by a central processing unit through control or driver circuit elements respectively associated with corresponding electrical devices, said wiring system comprising: a main cable (56) including a signal transmission path (56S) for transmission of signals, in a multiplex mode, to be sent from or applied to the central processing unit (52) and a power transmission path (56P) for transmission of power to be fed from a power source (50); and a connector provided for each of groups (60A, 60B, ... 60J) of electrical devices, each group including those electrical devices (60A J , 60A 2 , 60A3) which are in close to each other, said connector including a housing (2), a terminal controller (54A, 54B, ... 54J) having control or driver circuit elements (16, 34) associated with the electrical devices of the group and integrally mounted in the housing, means (18) extending exteriorly of the housing for connecting the terminal controller to the main cable, and means (10) extending exteriorly of the housing for connecting the terminal controller to the electrical devices of the group.
Claim 2
Dependent Claim 204 words
A multiplexed wiring system for use with a vehicle having a centralized control system in which various electrical devices located at different portions of a vehicle are centrally controlled by a central processing unit through control or driver circuit elements respectively associated with corresponding electrical devices, said wiring system comprising: a main cable (56) including a signal transmission path (56S) for transmission of signals, in a multiplex mode, to be sent from or applied to the central processing unit (52) and a power transmission path (56P) for transmission of power to be fed from a power source (50); and a connector provided for each of groups (60A, 60B, ... 60J) of electrical devices, each group including those electrical devices (60A J , 60A 2 , 60A3) which are in close to each other, said connector including a housing (2), a terminal controller (54A, 54B, ... 54J) having control or driver circuit elements (16, 34) associated with the electrical devices of the group and integrally mounted in the housing, means (18) extending exteriorly of the housing for connecting the terminal controller to the main cable, and means (10) extending exteriorly of the housing for connecting the terminal controller to the electrical devices of the group.
Claim 3
Dependent Claim 55 words
A multiplexed wiring system according to claim 1 wherein said means (18) for connecting the terminal controller to the electrical devices comprises a set of terminals (10) respectively connected to the corresponding circuit elements associated with the electrical devices in the same group and removably connected with terminal sockets (62) connected to said electrical devices.
Claim 4
Dependent Claim 31 words
A multiplexed wiring system according to claim 2 wherein said terminal controller and portions of said terminals confined in said housing are molded with resin inside said housing of the connector.
Claim 5
Dependent Claim 42 words
A multiplexed wiring system according to claim 2 wherein said terminal controller and portions of said terminals confined in said housing are covered on their surfaces with an insulating material and securely molded with an iron powder containing resin inside said housing.
Claim 6
Dependent Claim 99 words
A multiplexed wiring system according to any one of claims 1 to 4 wherein said signal transmission path (56S) of the main cable comprises an optical fiber, said means (18) for connecting the terminal controller to the main cable comprises a branch optical fiber (20) connected to the optical fiber of said main cable, and said terminal controller comprises converter means (38, 40) for converting a light signal transmitted from the branch optical fiber into an electrical signal and converting an electrical signal delivered from any of the control circuit elements of said terminal controller into a light signal.
