## Background
FIELD OF THE INVENTION
The present invention relates to a connector, in particular to an improved eSATA connector structure.
BACKGROUND OF THE INVENTION
In general, an eSATA connector includes a base, a plurality of conductive pins and a metal casing. In a manufacturing process, a thin metal sheet is stamped to produce the conductive pins. After the base made of a plastic material is formed in an injection molding process, the conductive pins are combined with the base, or the stamped conductive pins are placed into a mold and then integrally formed with the base by the injection molding process, such that an end of each conductive pin is fixed onto a tongue plate of the base, and another end of each conductive pin is extended to the exterior of the metal casing after the base is assembled with the metal casing.
Since the base and the conductive pins of the eSATA connector are manufactured separately, small flexible pillar-shaped objects will be produced after the conductive pins are formed by the stamping process, and thus it is not easy to install the eSATA connector into a pin slot of the tongue plate of the base. If the conductive pins are placed into the mold and integrally formed with the base by the injection molding process, and the conductive pins and the base are not connected closely enough, ends of the conductive pins may be warped slightly, such that after a plug of an external eSATA transmission line is inserted, the conductive pins may be crooked or unable to contact with the pins in the plug of the eSATA transmission line, and thus resulting in a failure of transmitting electric signals.
If an electronic component is installed or added inside the eSATA connector or an electronic circuit (including a circuit board) is expanded, the conventional eSATA connector has very limited internal space, such that the electronic component or electronic circuit cannot be added, or after the electronic circuit (including a circuit board) is added into the eSATA connector directly, the new-generation eSATA connector becomes larger and incompatible with the use of other mainboards.
SUMMARY OF THE INVENTION
In view of the aforementioned shortcomings, a primary objective of the present invention is to use a copper-foil circuit on a circuit board to replace the conventional design of the conductive pins formed by stamping. Meanwhile, an electronic component or circuit is manufactured on the same circuit board to make the manufacture of the eSATA connector much easier, when it is necessary to add the electronic component or circuit.
To achieve the foregoing objectives, the present invention discloses an improved eSATA connector structure, comprising:
a base, having a containing space defined therein, a retaining wall formed at a front end of the containing space, and an opening formed on the retaining wall, a slideway formed between two sidewalls of the containing space, a bottom tray extended from the bottom of the retaining wall, a gap formed between the retaining wall and the bottom tray, and an engaging portion formed at the bottom of both sidewalls of the containing space and provided for assembling the chassis;
a circuit board, installed in the containing space, and having a plurality of conductive pins made of copper foils, a transmission line segment extended from an end of each conductive pin, and a soldering hole formed at an end of the transmission line segment and soldered to the conductive terminal;
a chassis, having a tray portion coupled onto the base, a retaining portion bent from an end of the tray portion and coupled to a rear side of the base, a plurality of through holes formed on the tray portion and provided for passing the conductive terminals out of the through holes respectively, and a bump formed separately on both lateral sides of the tray portion and coupled to the engaging portion; and
a casing, having a hollow main body, a port formed at a front end of the main body, a plurality of elastic plates disposed at the top and bottom of the port respectively, a folding plate disposed at an end of the hollow main body, such that when the base is assembled in the main body, the folding plate is bent to prevent the base from being loosened.
