ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a modularized electric connector, and more particularly to such a modularized electric connector that enables the user to connect a plurality of modularized electric connectors positively in a row without the use of a tool or any fastening elements.
FIGS. 5 and 6
show an electric connector for use in a printed circuit board to receive an electric plug for electric signal transmission. This structure of electric connector must be individually installed. When multiple electric connectors are used and arranged together, fastening means must be used to secure the electric connectors in position. In making an electric connector device having multiple connector units, the manufacturing procedure is complicated, and the manufacturing cost is high.
SUMMARY OF THE INVENTION
It is the main object of the present invention to provide a modularized electric connector, which allows the user to connect a plurality of modularized electric connectors positively in a row without the use of a tool or any fastening elements. According to the present invention, the modularized electric connector comprises a housing, a terminal holder having a flat horizontal base fastened to the housing and a vertical block disposed outside the housing, and a plurality of terminals installed in the terminal holder. The housing comprises a longitudinal coupling tongue and a longitudinal coupling groove respectively provided at two opposite sides near the top, and two locating flanges respectively provided at two opposite lateral sides at different elevations near the bottom. The terminal holder comprises two vertical coupling flanges reversely arranged at two opposite sides. The longitudinal coupling tongue, longitudinal coupling groove and locating flanges of the housing and the vertical coupling flanges of the terminal holder are so arranged that when two modularized electric connectors are arranged together, the longitudinal coupling tongue at the housing of a first modularized electric connector can be coupled to the longitudinal coupling groove at the housing of a second modularized electric connector, enabling the locating flange at one side of the housing of the first modularized electric connector to be pressed against the locating flange at one side of the housing of the second modularized electric, and the coupling flange at one side of the vertical block of the terminal holder of the first modularized electric connector can be coupled to the coupling flange at one side of the vertical block of the terminal holder of the second modularized electric connector.
