ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electric connector, and more particularly to such an electric connector, which comprises a connector body and a partition frame fastened together to hold a set of signal terminals, and an angled positioning terminal coupled between the connector body and the partition frame to secure the connector body and the partition frame in position. The positioning terminal comprises hooked retaining arms respectively hooked in a locating hole at the connector body, two mounting legs respectively inserted through respective locating holes at the partition frame, and a locating notch engaged with a locating block at the partition frame.
FIG. 6
shows an electric connector with angled terminals according to Taiwan Patent Publication No. 308375. This structure of electric connector comprises a connector body holding a set of terminals, a metal shell covered on the connector body at the front side, a partition frame fastened to the connector body at the back side to support the terminals, a fastening device fastened to the connector body and the partition frame for grounding. The fastening device secures the connector body and the partition frame together. This structure of electric connector is still not satisfactory in function. Because the fastening device has a complicated structure, its manufacturing cost is high. Further, the coupling structure between the fastening device and the partition frame is complicated. It takes much time to fasten the fastening device to the partition frame and the connector body.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide an electric connector, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, the electric connector comprises a connector body having rows of terminal slots and a locating slot, a partition frame coupled to the connector body, a set of signal terminals respectively mounted in the terminal slots at the connector body and respective insertion slots at the partition frame, and a positioning terminal fastened to the locating slot at the connector body to hold down the partition frame, wherein the locating slot of said connector body comprises a sloping guide wall portion at a rear end thereof and a retaining wall portion at a front end thereof; the positioning terminal comprises a first flat coupling wall and a second flat coupling wall connected at right angles, two sloping edges respectively provided at top and bottom sides of the first flat coupling wall and stopped at the sloping guide wall portion in the locating slot at the connector body, two springy retaining arms forwardly extended from the sloping edges at the first flat coupling wall and inserted into the locating slot at the connector body, the retaining arms each having a hooked portion respectively hooked on the retaining wall portion in the locating slot at the connector body, and two elongated clamping strips forwardly extended from the first flat coupling wall between the retaining arms. By using a tool to squeeze the hooked portions of the retaining arms toward each other, the positioning terminal can easily be disconnected from the locating hole at the connector body. According to another aspect of the present invention, the partition frame comprises two locating holes and a locating block disposed between the locating holes, the positioning terminal comprises two mounting legs downwardly extended from the second flat coupling wall thereof and respectively mounted in the locating holes at the partition frame, and a locating notch disposed at the bottom side of the second flat coupling wall and forced into engagement with the locating block at the partition frame.
