摘要:
An electrical connector assembly includes a cassette (10) and a receptacle (20) electrically and mechanically coupled together. The cassette (10) includes a housing (11) encompassing a printed circuit board and a plurality of electrical contacts (30) in connection with terminals on the circuit board and disposed at a bottom surface of the cassette housing (11) for exterior connection thereto. The receptacle (20) includes a housing having a cavity (21) for receipt of the cassette (10) therein. The cavity (21) is of size to accommodate rotation of the cassette (10) in the cavity (21) from an insertion position to a latched position. The receptacle (20) housing includes a plurality of spring contacts (31) and adjacent the bottom of the cavity (21), the spring contacts (31) being electrically engaged by the contacts (30) on the cassette (10) upon insertion of the cassette (10) into the receptacle cavity (21). The receptacle housing includes a pair of spaced opposing pins (41) projecting into the cavity (21) that enter and engage slots (40) formed on the lower sides of the cassette (10). These pins (41) and slots (40) provide a stop surface to prevent overstressing the spring contacts (30, 31) during insertion and rotation of the cassette (10) and also provide a pivot on which the cassette (10) is rotated from the insertion position to the latched position.
摘要:
A solar panel module for directly mounting to a roof surface comprises a plurality of solar panels and a low profile, elongated frame including a generally flat, rectangular base having a plurality of substantially planar surfaces for supporting the under surfaces of the solar panels. The panels are removably sealed to the frames at the under surfaces thereof, rendering the upper surfaces fully free and unencumbered for receipt of incident solar radiation. The frame includes, integrally therewith, upstanding walls adjacent opposite edges of the panel supporting surfaces, defining raceway channels for concealed passage of electrical wires connected to the solar panels. The channels and walls have provision for overlapping interlocking with similarly fabricated frames for ease of installation, weather-proofing and high-density panel mounting.
摘要:
A connector for impedance matched, low capacitance connection to coaxial cable is disclosed. The connector includes a conductive housing which supports in electrical isolation an insulation displacing electrical contact. A clamping element forces the center conductor of the coaxial cable down onto the insulation displacing portion contact for electrical termination. An assembly nut supports the drain wire of the coaxial cable, in electrical engagement therewith, to place the connector housing in electrical continuity with the drain wire of the cable.
摘要:
A lead member comprises a plurality of leg pieces (1), an interlink plate (2) for holding the leg pieces (1) spaced from each other at predetermined intervals to thereby interlink respective one ends of the leg pieces (1). Terminal portions (3) are provided at the respective other ends of the leg pieces (1) to attach to a PCB (4), a wire (5) or the like. Each of the leg pieces (1) is folded to overlap the interlink plate (2) so as to form a leg portion (1) at the folded section, the leg portion (1) being insertable into predetermined openings in another PCB (6) or substrate.

An electronic package is disclosed including a socket assembly (40) for connecting an electronic component (10) to a circuit board (12). A header (20) is secured to the circuit board (12), and receives the socket assembly (40) which is connected to the header (20) along a direction parallel to the plane of the circuit board (12). The socket assembly (40) includes a housing (42) and tray (44). The tray (44) which accommodates the electronic component ,(10), is slidably inserted into the housing (42).
摘要:
A tubular wire marker sleeve (10) is disclosed. The sleeve includes a central portion (16) which is flattened by ultrasonic welding and end extends (18) which are unflattened facilitating insertion of an electrical wire into the sleeve (10). Plural sleeves (10) may be assembled on a support card for printing on the sleeve with a conventional typewriter or computer printer.
摘要:
A flat multiconductor cable power distribution system has a discrete wire multi-phase feeder, a main flat cable having at least four conductors, the cable being connected to the feeder to have plural phase energization. An insulation-piercing adapter overlies and is connected to the main cable and is energized with a selective one of the plural phases. In a particular arrangement, a secondary multiconductor cable is connected to the main cable by the adapter. A power outlet may be electrically connected to the secondary cable at the juncture of the main and secondary cables and the adapter.
摘要:
A method and apparatus for providing strain relief to a cable splice area is disclosed. A length of flexible cord (20) is secured to the cable (10) on each side of the splice (16). A frictional substrate (30) is supported over the cord (20) and the cable (10). The frictional substrate (30) is compressively secured to the cable (10) thereby frictionally supporting the cord (20) to the cable (10).
