INPUT CONNECTION DEVICE

Description

FIELD OF THE INVENTION

[0001] The present disclosure relates to a connection device, and more particularly to an input connection device applied to an electronic device for reducing the cost and the volume and improving the electromagnetic interference thereof.

BACKGROUND OF THE INVENTION

[0002] Nowadays, input connection device has been widely applied to a variety of electronic devices or equipment for conveying electric power or transmitting signal information from an external source to the electronic device. With increasing development of science and technology, the general trends in designing electronic devices are toward minimization, high integration and low cost. The structure design and the practical demand of the input connection device are more difficult. Therefore, it is important to develop an input connection device with miniaturized size and low cost.

[0003] Generally, the input connection device includes a plurality of electric connectors, a plurality of first power wires, a printed circuit board, a second power wire and a switch. Each electric connector is mounted on a sidewall of a cabinet of the electronic device. One end of each first power wire is connected with the corresponding electric connector, and the other end of each first power wire is connected with the printed circuit board, which is disposed in the cabinet. One end of the second power wire is connected with the printed circuit board, and the other end of the second power wire is connected with the switch. Therefore, when the electric connector receives electric power or signal information from an external source, the electric power or the signal information is transmitted from the electric connector to the switch through the first power wire, the printed circuit board and the second power wire.

[0004] However, if the number of the electric connectors is increased, the number of the first power wires is increased accordingly. Consequently, the cost and the volume of the input connection device are increased. Moreover, assembly method of the input connection device is complicated and wire organization is difficult because of the plurality of first power wires, and incorrect connections between the first power wires and the electric connectors may occur easily. Furthermore, the first power wire generates additional electromagnetic interference on the input connection device, which may degrade the performance of the electronic device.

[0005] US 6 950 311 B1 relates to a telecommunication switch/server. The switch has a passive section and an active section or tray that may be docked to the passive section. The passive section contains only the physical interfaces to the switch's external data and telephony networks and power input. It is not intended to be a field replaceable unit and is therefore intended to be mounted in a rack system with all of the power and communications cables attached thereto. The telephony and data ports are routed from the passive section to the active section via connectors on the two sections as well as to a redundancy connector on the passive section that may be physically connected by a cable to a slave unit in a redundant application. The active section or tray contains all of the active components of the switch and is inserted via guides into the passive section. The tray is considered a field replaceable unit and can be inserted into and extracted from the passive section while the system is powered up and operational. As a result of its unique two-section design, the present switch has several advantages. For example upon failure, all active components of the system may be replaced without removing the mounting hardware from the rack in which the switch is mounted and without removing any cables connected to the switch. Also when the switch is part of a redundant system, when the switch fails, all of the active components of the switch may be replaced without interrupting system operations.

[0006] EP 0 094 823 A2 discloses a DC power supply unit. Described is an arrangement for mounting a DC power supply unit which includes a single circuit board on which there are provided an input circuit and a stabilizing circuit having circuitry for rectification of alternating current and for stabilization of direct current. The input circuit is composed of such electrical components as an input connector, a power supply switch and a fuse holder each of which has an operating portion which must be accessed from outside a cabinet housing the DC power supply unit. The cabinet is provided with an opening, and the electrical components are so arranged that the operating portions thereof are located at the opening for easy access from outside the cabinet.

[0007] US 2005/213300 A1 relates in general to a computer switch box. A computer system including a switch box and bracket assembly including one or more manual switches are provided for controlling the selective activation and deactivation of the computer systems' memory storage devices and network system. Preferably, the computer system includes a wire harnesses including a network cable for connecting a network to the bracket assembly's input port, a relay cable for connecting the bracket assembly's output port to the computer's network port and a manual switch. Instead of network communications being transmitted directly from the network to the network port, the signals are rerouted through the bracket assembly's input port, manual switch and output port, and then routed to the computer's network port. Access to the network is then controlled by simple manual manipulation of a button, toggle or knob to create an open or closed circuit.

[0008] Therefore, there is a need of providing an input connection device so as to overcome the drawbacks of the conventional technologies.
