Abstract: A plug connector includes plastic covers, a mating portion and a latch. The plastic covers include an upper plastic cover and a lower plastic cover, the two plastic covers buckling with each other and forming a space. The mating portion which is fixed in the space includes a shell. A hook aperture is located on the front of the shell. The latch, which is fixed into the space, has two barricades. Each barricade stretches forward and forms an arm. Each arm has a hook at its head. The hooks pass through the hook apertures and project outwardly, wherein each barricade of the latch protrudes upward and forms a locating bulge. Correspondingly two locating cavities are defined inside the top surface of the upper plastic cover. The locating bulges are inset into the locating cavities.

Abstract: An insulation displacement connection (IDC) connector assembly includes an IDC connector and external cables. The cables are inserted in the IDC connector through passageways disposed in a surface of the IDC-connector to be terminated to the IDC connector. A positioning recess is defined in the top surface of the IDC connector corresponding to each cable and each communicates with the corresponding passageway and is exposed to surfaces adjacent to the surface mentioned above.

Abstract: The present invention provides a module connector including a housing having four sidewalls that define a chamber for receiving a module therein. Each sidewall defines a plurality of contact recesses. A plurality of contacts is accommodated in the contact recesses and electrically contacts with the module. Pull-out prevention slices are positioned on periphery of the housing. Each pull-out prevention slice has a pressing portion which extends into the chamber and presses on the top of the module downwardly, and an actuating portion which extends upwardly from the pressing portion and is adapted for being manually pulled outward. When the module is needed to be pulled out from the module connector, by pulling the actuating portion outward, the pressing portion is driven to move outward and upwardly with the result that the pressing portion departs from the module to make way to the module for the module being pulled out. Therefore, no special tool is needed, in turn, the module is avoided being scraped.

Abstract: The present invention discloses a flexible printed circuit board connector including a housing, a sliding cover and a pair of support nails. A pair of guiding grooves and insertion holes is defined in sidewalls of the housing for receiving the support nails. A protruding portion is formed on each support nail to form a pivotal hole between the protruding portion and inner surfaces of the groove. The sliding cover has a pair of cam shafts rotatably supported in the pivotal holes. The cross section of each cam shaft has an utmost protrudent point which brushes past an inner surface of the pivotal hole when flipping the sliding cover. The length of the longest chord of the cross section that passes the utmost protrudent point is longer than the distance between the inner surface brushed by the utmost protrudent point and its opposite inner surface of the pivotal hole.

Abstract: A dustproof receptacle connector includes a dielectric housing having a cavity. A plurality of terminals and a dustproof means are received in the cavity. The back end of the dielectric housing is a closed end. A pair of guide grooves are defined in lateral sides of the cavity. The dustproof means includes a dustproof cover and a plurality of springs. The dustproof cover has a plate. A pair of arms extend from two opposite sides of the plate respectively. A pair of positioning pillars are defined in the inner side of the plate. The springs twine on the positioning pillars and the arms slide in the guide grooves. A block protrudes inwardly from the inner side of each arm respectively to increase the anti-stress intensity of the arms.

Abstract: The present invention provides a runner system for a plastic injection mold through which molten plastic is injected into a mold cavity defined between two mold halves. The runner system includes two mold cores each of which has a slot, a clamping plate for clasping the two mold cores and combing the slots to define therebetween a runner, and a sprue extending through one of the mold halves and connecting an entrance of the runner. The clamping plate and the clasped two mold cores are embedded into the other mold half. The clamping plate defines a gate connecting an exit of the runner to said mold cavity. The clamping plate seals at least a portion of the joint formed between the two mold cores and adjacent an exit of the runner to prevent molten plastic material from flowing into the joint to form seaming lines on surfaces of molded plastic articles. Thereby, the molded plastic articles have smooth surfaces without seaming lines.

Abstract: A module connector includes an insulated component, a plurality of contacts inside the module connector and a housing shell outside of the module connector. The insulated component has four sidewalls that define an inserting space to receive another module. Each sidewall has a plurality of contacts parallel L-shaped slots to accommodate the contacts that are electrically connected with the outside module. The housing shell has four side containing walls. A pressing pin and an elastic pin are extended from the top of each side-containing wall towards the inserting space. The pressing pins prop downwardly the outside module.

Abstract: The present invention provides a module connector including a housing having four sidewalls that define a chamber for receiving a module therein. Each sidewall defines a plurality of contact recesses. A plurality of contacts is accommodated in the contact recesses and electrically contact with the module. A pivotal cover has a top pressing cover, at least a pivotal arm and at least a locking claw extending downwardly from the top pressing cover. The pivotal arm pivotally mounts the pivotal cover on the housing to enable the pivotal cover to pivot between an open position to enable the module to be inserted in the chamber and a closed position with the top pressing cover pressing downwardly on the top of the module to prevent the module from being pulled out. The locking claw latches the pivotal cover in the closed position.

Abstract: A flexible printed circuit connector includes a housing with contact chambers for receiving a plurality of contacts. The housing sets engagement recesses, first sliding grooves and protrusions on both side surfaces thereof. A bottom cover is mounted on the housing at the underside thereof to define a first receiving space for receiving a first flexible printed circuit. A top cover is mounted on the housing on the top thereof to define a second receiving space for containing a second flexible printed circuit. The top cover is engaged with the bottom cover to retain the two flexible printed circuits reliably and precisely.

Abstract: An electrical connector latching apparatus comprises a supporting arm, a latching pivot formed at top portion of the supporting arm, an elastic arm formed at lower portion of the supporting arm, a base arm extending from the lower portion of the elastic arm and a free contact extending vertically from the base arm. A smooth curved surface forms at top portion of the latching pivot and a fixed support portion forms at bottom portion of the latching pivot. The smooth curved surface consists of at least two surfaces having different curvature, thereby the latching pivot slides into a pivot hole of the mated connector neatly. The latching pivot has an indentation-curved surface at its bottom to define the fixed support portion. An angle between the fixed support portion and the supporting arm is a special angle, so that the fixed support portion latches a mated connector firmly. Further the electrical connector contacts with the mated connector electrically and reliably.

Abstract: A board-to-board connector comprises a receptacle and a plug. The receptacle is composed of a receptacle housing and a plurality of first terminals parallelized. The plug is also composed of a plug housing and a plurality of second terminals parallelized. Meanwhile, the present invention provides a first design which forms a projection on the second terminal, a second design which defines a flange on the receptacle housing and a first wedge hole on the plug housing in accordance with the flange, and a third design which forms a retention portion and a locking portion on the first terminal and a second wedge hole on the plug housing in accordance with the locking portion, thereby avoiding terminals yield and providing a stable improved retention between the receptacle and the plug.
