An electric connector fastener including a female retaining plate made for fastening up with a male retaining plate, and a press block fastened to the female retaining plate for release control, the female retaining plate having a hook hole extended from an angled front end thereof adapted for receiving the male retaining plate, an arched notch at an inner side of its angled front end in communication with the hook hole for engagement with a raised portion of the male retaining plate, an axle housing transversely disposed in the middle for installation, a returned springy tail having an angled end piece, and two retaining holes longitudinally spaced between the springy tail and the axle housing, the press block having a longitudinal track defined within a bottom channel thereof into which a part of the female retaining plate is inserted, and two sloping retainer blocks spaced inside the bottom channel and respectively forced into engagement with the retaining holes of the female retaining plate.

A computer plug connector fastening mechanisms comprising two rectangular frames formed in an outer shell of a computer plug connector at two opposite lateral sides. The frames have two clamp holders respectively fastened therein to hold two clamping devices which are inserted therethrough for clamping the computer plug connector to a computer plug socket. The clamp holders each ave two parallel side walls on which a hook portion is formed to engage to elongated grooves on the inner wall surface of the frames. A front portion of the clamp holders includes an inward raised portion, an insertion hole, a through hole, a stopper, and a projected hook. The clamping devices each have a metal clamping plate which has hole near its front and includes an inward and forward extended L-shaped hook plate that includes an oblique hook. When the clamping devices are inserted into the slots of the plug connector shell, the L-shaped hook plates and the oblique hooks pass through the insertion holes and the through holes on the raised portions of the clamp holders, respectively, while the oblique hooks are retained by the stoppers. The front holes engage with the projected hooks of the raised portions of the clamp holders, permitting the computer plug connector to be quickly and firmly connected to a computer socket connector.

An electrical connector having a locking member which includes at one end an anchoring part shaped for hooking a mating connector, an engagement part to be secured to one of projections provided on both sides of a shell enclosing a main connector body, and at the other end a knob portion having a leaf spring. The engagement part is positioned between the anchoring part and the knob portion. The engagement part has a protrusion near to the center of the width of one end adjacent the knob portion, and two plate pieces on both the sides of the protrusion. Each of the plate pieces has a free end in the form of a resilient cantilever directing toward the protrusion. The spacing between the free ends of the two plate pieces is less than the width of the projection of the shell.

Disclosed is an improved connection device of a computer connector, comprising a clip piece including a metal leaf spring and a press cap fixed to a top of the metal leaf spring, and an insertion socket provided in a clip room formed at one side of an inner shell of said connector; the metal leaf spring of the clip piece having a bottom end formed with two hooks for firmly hooking on a head portion of a connector on the computer; the connection device being characterized by that the insertion socket is formed from a middle portion of a side wall of the inner shell which upward and inward projects toward the connector, forming an insertion plate and an insertion opening over said insertion plate, that a through hole is provided above the insertion opening, and a stop plate is formed between the through hole and the insertion opening, and that the clip piece has an inwardly protruded .left brkt-top.-shaped hooking plate formed at a predetermined position corresponding to the insertion plate, such that when the clip piece is inserted into the insertion socket, the hooking plate thereof extends into and through the through hole and the insertion opening, causing the clip piece to be directly clamped in place between the insertion plate and the stop plate.

An I/O connector has a housing with front, rear and top openings. Set within the housing is a monolithically formed latch. This latch has first and second tines. The first tine has a notch at its front end for engaging with an appropriate locking niche on the portable communications device, and a button at its back end. The button protrudes through the top opening of the housing, and the front ends of the tines protrude through the front opening of the housing. By pressing on the button, the first tine is depressed towards the second tine, which unlocks the I/O connector from the locking niche. The second tine is slightly longer than the first tine to ensure that the first tine stays locked within the locking niche.
