Abstract:
An electrical connector (1/1A) for either through hole mounting or surface mounting comprises a common dielectric housing (10), a plurality of terminals (12) retained therein, and a pair of securing devices (20 or 120) mutually exclusively fixed in the housing. The securing devices are either a pair of board locks (21) or a pair of soldering pads (121). A mounting face (10b) of the housing forms two pairs of standoffs (15) at its opposite ends, and each pair of standoffs defines an opening (15a) therebetween. A retaining recess (14) is defined in the housing within each opening. The boardlocks (21) or soldering pads (121) each form a base portion (21a or 122) which engages with a retaining recess. A fork portion (21b) of each board lock engages with a retaining hole in a circuit board for through hole mounting, and a soldering portion (123) of each soldering pad engages with a mounting pad of a circuit board for surface mounting.
Abstract:
A FFC connector comprises a dielectric housing having top and bottom faces. The top face defines an elongate slot extending into the housing and the bottom face defining an entrance in communication with the elongate slot for insertion of a FFC cable. A plurality of terminal cells is defined in the housing and each terminal cell being in communication with the elongate slot. A plurality of terminals is assembled in the terminal cells and each terminal includes a base portion received in the housing and a spring arm extending from the terminal cell into the elongate slot. The terminal further forms a soldering tail for mounting to a printed circuit board.
Abstract:
An electrical connector having a number of electrical contact in which a contact portion of each contact extends diagonally forward to engage a received, mating contact. Each electrical contact has a first leg anchored in an insulative housing of the connector and a substantially free second leg flush with a wall of a cavity formed in the connector. The contact portion of the electrical contact has an angled end consisting of a narrow neck and a large sector, the large sector gradually enlarging toward a free end thereof. The substantially free second leg of the electrical contact is spring biased against the wall of the cavity only upon insertion of a mating contact into the cavity to achieve a smooth insertion of the mating contact into the cavity.
Abstract:
A method of interconnecting a data access device to a main board for notebook computers without requiring a flexible printed circuit assembly and a connector module. The method involves interconnecting a simple circuit board between a connector interfacing the data access device and a connector interfacing the main board. The circuit board serves to convert the number of contacts of one of the two connectors to be in electrical and mechanical conformity with the number of pins of the other connector. The connector module employs the circuit board which is adapted to be directly interconnected between the first and second connectors.
Abstract:
An IDC type terminator (10) includes a housing (12) having a plurality of passageways (18) extending therethrough in the vertical direction. A plurality of contacts (20) are respectively received within the corresponding passageways (18). The upper and lower portions of the contacts (20) respectively and oppositely extending out of the housing (12) wherein the upper portions engage the PC board (15) which vertically stands on the housing (12), and the lower portions engage the corresponding flat cable (34) which is sandwiched between a bottom cover (16) and the housing (12). Opposite to the bottom cover (16), a top cover (14) is attached to the housing (12) for shielding the PC board (15) therein. A pair of cavities (22) are positioned on two opposite ends of the housing (12) so that the latches (58, 64) of the top cover (12) and of the bottom cover (14) may commonly but oppositely side by side occupy the corresponding cavity (22). Therefore, the latch (58) of the bottom cover (16) can be hooked against the inner shoulder (52) of the housing (12), and the latch (64) of the top cover (14) can be hooked against the bottom surface (42) of the housing (12) wherein once the top cover (14) and the bottom cover (16) have been completely and actually reach their fixed positions regard to the housing (12), the latches (58, 64) of the top cover (14) and of the bottom cover (16) can not be released from their locking positions so that the housing (12), the top cover (14) and the bottom cover (16) are reliably assembled together as one piece without risk of dissembling.
Abstract:
A method for preparing a purple sweet potato concentrate that is free from starch, rich in anthocyanins, phenolic compounds, minerals, and soluble dietary fiber with low viscosity, attractive color, and with natural sweetness is presented. The method first prepares and liquefies the purple sweet potatoes and fixes the colorization by adjusting the pH value. Next, amylase and an enzyme complex of hemicellulase, pectinase, cellulase, glucoamylase and protease are added in sequence under conditions effective to produce the juice with the above mentioned properties. The juice is then centrifuged and membrane-filtered to produce a purified purple sweet potato juice which is vacuum-concentrated to yield a purple sweet potato concentrate. Purple sweet potato powder can be obtained by vacuum drying the sediment and concentrate mixture.
Abstract:
A cable assembly comprises a housing including an upper cover and a lower cover assembled with each other and a pair of first and second printed circuit boards (PCBs) received in the housing and sandwiched between the upper and lower cover. The upper cover defines a number of protruding portions formed therein. Each of the protruding portion defines two steps thereon. The first and second PCBs are spaced apart from each other along a vertical direction by the two steps of each of the protruding portions. The first and second PCBs respectively define a plurality of first and second openings cooperating with corresponding protruding portions.
Abstract:
A cable end connector includes an insulating housing defining a rear cable-location portion thereof, a plurality of conductive terminals including contacting portions and terminal portions located in the rear cable-location portion, a plurality of cables each having wires and a connecting bar defining a first touching end and a second touching end. The wires of the cable overlap the terminal portions one by one except one wire and one terminal portion. The first touching end overlaps one terminal portion and the second touch end overlaps said one wire so as to establish an electrical connection through the connecting bar between said one terminal portion and one wire.
Abstract:
An adapter includes a plug connector having a first housing defining a first mating port and a plurality of first terminals disposed in the first housing, and a receptacle connector having a second housing defining a second mating port and a plurality of second terminals disposed in the second housing and electrically connecting to the first terminals. An optical device has a first optical module and a second optical module optically connecting with each other via optical fibers. The first optical module is movably retained in the first housing while the second optical module is immovably retained in the second housing along a mating direction of the receptacle connector.
