Abstract: An electrical connector has an insulative housing, a plurality of terminals and a metal shell. The terminals are mounted through the insulative housing and each terminal has a mounting section, a contacting section and a soldering section. The soldering sections of all the terminals are arranged in triangular patterns. Each soldering section is located in a tip of one triangular pattern. Distances between one soldering section and adjacent soldering sections are substantially identical. The triangular patterns of the soldering section stabilize the impedance of the operating electrical connector. Therefore, the electrical connector is stable and reliable.

Abstract: A mini plug connector has an insulative housing, a plurality of terminals and a metal shell. The insulative housing has a base, a tongue and a plurality of mounting holes. The tongue protrudes from the base and has a top, a space and at least one top elongated recess. The space and the at least one top elongated recess are defined in the top of the tongue. The terminals are mounted respectively through the mounting holes. The metal shell covers the insulative housing. The at least one top elongated recess prevents the insulative housing from being defective and deforming when the insulative housing is manufactured by an injection molding process.

Abstract: A receptacle connector comprises an inner housing, multiple first pins, multiple second pins, an outer housing, an inner casing and an outer casing. The first pins and the second pins are mounted through the inner housing. The outer housing is mounted around the inner casing. The outer casing is a folded sheet of metal and is mounted around the outer housing.

Abstract: A plug connector is engaged detachably with a socket connector having a shell and two positioning holes defined through the shell. The plug connector has an insulative housing, a plurality of terminals, a shell and a pair of positioning hooks. The insulative housing has a pair of mounting blocks. The terminals are mounted in the insulative housing. The positioning hooks are mounted respectively through the mounting blocks and each positioning hook has a root, a hooking arm and a fastening arm, the hooking arm mounted through one mounting block and has a hook portion formed on the hooking arm and hooking one positioning hole of the shell of the socket connector. With the positioning hooks, the plug connector is engaged securely with the socket connector without inadvertently falling off.

Abstract: An electrical connector including a jack and a plug is disclosed. The plug includes a spring biased push button slidably anchored in an opening on a top shell and including an indentation at either side, and a front trigger adjacent the indentation; two U-shaped positioning devices each comprising a front first protrusion at one end and an intermediate second protrusion; and a shield case comprising a grounding plate. The push button is pushed forward to engage with a front end of the opening in an inoperative state. The push button is adapted to push rearward to cause the trigger to push and press down the second protrusions until the first protrusions clear internal openings of the jack such that a subsequent pulling will disengage the plug with the jack.

Abstract: The present invention provides a high definition multimedia interface (HDMI) connector, comprising an insulating housing, a terminal line separator, a metallic shell, a plurality of puncture terminals, a plastic outer shell and a front cover, wherein said terminal line separator consists of the terminal fixing plate and line binder, said puncture terminal is inserted in the insulated housing, the conduction lines are lined up on the line binder and punctured contact with the puncture terminals, followed by placing in the terminal fixing plate to secure the spacing among the puncture terminals, said metallic shell is consisted of the front and rear shell, wherein the insertion portion and the front metallic shell are further interlocked by use of the latch slot at the rear end of the metallic front shell and the latch lug on the insertion portion of the insulated housing, followed by incorporating the metallic rear shell to form a compact metallic unit, said metallic unit is then placed into the plastic outer

Abstract: The present invention relates to a HDMI connector comprising of an insulated housing, a metallic housing and a contact terminal unit. The insulated housing is standardized but the metallic housing and the contact terminal unit are modified and combined with the insulated housing to form the HDMI connector of the present invention. The metallic housing is modified to have a flange or no flange and to have vertical insertion type pins or horizontal SMT type pins, and the terminal contact unit attached thereto. The terminal unit is modified to have spikes whose rear ends are either bent and flattened to form horizontal SMT type terminal solder pins or to have spikes whose rear ends are not bent and not flattened to form vertical insertion type pins.

Abstract: A banknote-validating machine equipped with security device is provided. The security device is installed inside the banknote receiver of the banknote-validating machine. The banknote receiver has an upper chassis and a lower chassis, and a banknote channel is formed between the upper chassis and the lower chassis. The distal end of the banknote channel is conjoint to the inner part of the banknote entrance slot on the front panel. A sensor is positioned at a primal end of the banknote channel. A security plate is positioned at the upper chassis. The sensor is adapted for sensing the length of the banknote entering banknote channel and the time taken for the banknote to pass the banknote channel. The security plate is adapted for blocking the banknote. Thus, the security device has multiple security functions for preventing the banknote from being pulled out by an external force.
