ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical connector, and more particularly to an electrical connector having barrier for preventing sparks generated between adjacent terminals carrying high voltage.
DESCRIPTION OF THE PRIOR ART
Each computer is equipped with a power supply system which supplies power to a motherboard, and pertinent electrical devices, such as a floppy disk drive, hard disk drive and CD-ROM. Conventionally, the power supply system includes a plurality of harnesses interconnected between the motherboard, floppy disk drive, hard disk drive and CD-ROM and the power supply. Each harness includes a cable end connector. When the power supply is to be removed or changed, the connectors attached to the electrical devices shall be firstly disconnected, then the power supply can be removed.
In order to increase the efficiency of assembly, an enclosure of the computer is provided with a bay in which the power supply is seated. An end wall is provided with a connector coupled to a connector of the power supply system. By this arrangement, the power supply system can be conveniently inserted thereto or withdrawn therefrom.
In one of the application, a so called Distribution Power System (DPS) is right now under developing and equipped with a DPS connector which serves both signal and power transmission. Except the terminals for power supply, five pins are allocated for the field replacement unit information on the DPS power supply connector. One pin is used for the serial clock, while another pin is used for serial data. About three to five pins are used for address lines to indicate to the power supply's EEPROM which position the DPS power supply occupies in the power bay. In order to prevent electrical sparks happened between the power terminals and the signal terminals, measurements shall be introduced thereof.
SUMMARY OF THE INVENTION
An objective of this invention is to provide an electrical connector having a cover enclosing insulation displacement sections thereof. One terminal carrying high voltage is separated with the rest terminals by a barrier extending from the cover.
In order to achieve the objective set forth, an electrical connector in accordance with the present invention comprises a housing having mating and rear surfaces, and defining first passageways between the mating and rear surfaces. A plurality of first terminals is assembled to the first passageways from the rear face. Each terminal has an insulation displacement section extending beyond the rear face. At least a slot is defined in the rear face separating at least one terminal from the rest of the first terminals thereby preventing sparks generated from therebetween. A cover is assembled to the rear face enclosing the insulation displacement sections of the terminals. The cover includes a barrier received in the slot of the housing thereby eliminating sparks resulted when the one terminal carries high voltage.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiments of the invention taken in conjunction with the appended drawings.
