ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector, and particularly to an electrical connector with a one-piece shell.
Taiwan Patent Application No. 88213348 discloses an electrical connector comprising an insulative housing having a plurality of terminal receiving channels retaining a corresponding number of terminals therein, and a shell covering outer faces of the insulative housing. Each terminal includes a solder tail for soldering to a cable and a mating portion for mating with a complementary connector. The terminals are produced on a common carrier strip and are all identical, so a distance between two adjacent terminals is very small, especially in a high-density connector. Therefore, the solder portions of the terminals are too difficult to attach to a cable. In addition, the fit of the insulative housing within the shell is not very firm because of their dove-tailed design.
Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide an electrical connector having a one-piece shell.
A second object of the present invention is to provide an electrical connector wherein the soldering portions of two adjacent terminals are offset in opposite directions from the connector providing wider separation between soldering portions and more convenient soldering connections to wires.
To fulfill the above mentioned objectives, an electrical connector according with the present invention comprises an insulative housing, a plurality of terminals received in the housing, a one-piece conductive shell, and an over-molded casing portion. The plurality of terminals are secured within a plurality of receiving channels defined in the insulative housing. The terminals are of two designs, produced on two different carrier stripes. Both terminal designs include a mating portion at one end and a mounting portion at an opposite end. The designs differ in that the soldering portion is level with the mating portion in one design, and is at an elevation above the mating portion in the second design. Also, the soldering portions are laterally offset in opposite directions relative to the plane of the mating portions. Terminals of the two designs are assembled into the connector in an alternating pattern, creating larger distance between adjacent mounting portions. The one-piece shell includes a first wall, a second wall, a third wall, a fourth wall, and a mating portion all being integrally formed from a metal sheet and folded into a rectangular main body and a smaller rectangular mating portion. A pair of protrusions on opposite sides of the insulative housing engage with a pair of second openings on opposite sides of the main body of the shell.
