An electrical cable end connector ( ) includes a pair of electrical connector components ( ), an electrical cable ( ), a pair of latches ( ) and a cover ( ). Each electrical connector component has an insulative housing ( ), a number of electrical contacts ( ) mounted to the insulative housing, a printed circuit board ( ) electrically connecting with the electrical contacts and a conductive shell ( ) enclosing the insulative housing, the electrical contacts and the printed circuit board. The electrical cable includes a number of conductors ( ) respectively electrically connecting with the printed circuit boards of the electrical connector components and a metallic braid ( ) electrically contacting with the conductive shells of the electrical connector components. The latches are retained to the cover. The cover has a pair of cover members ( ) to enclose the electrical connector components therein.

Cable end connector

A cable antenna includes a circuit board to which first ends of two antenna cables and a coupling cable are soldered. A second end of the coupling cable forms a connector for connection with a signal receiving/transmitting circuit. Each of the antenna cables has a second free end exposed to the atmosphere for receiving/transmitting electromagnetic signals. An outer jacket of each antenna cable is removed along a first predetermined length measured from the free end thereof to expose a braided shield. A second predetermined length of the braided shield measured from the free end is removed for exposing an inner dielectric layer that surrounds a core conductor. The second length is less than the first length thereby leaving a portion of the exposed braided shield on the inner dielectric layer. The braided shield that is cut from the cable is twisted to form an elongate consolidated conductor. The consolidated conductor made of the braided shield is then soldered to the portion of the exposed braided shield that is left on the inner dielectric layer thereby completing the cable antenna. Preferably, the consolidated conductor made of the braided shield is arranged to be substantially normal to a central axis of the cable. If desired, the core conductor may be bent 90 degrees off the central axis of the cable. The consolidated conductor made of the braided shield may be replaced by other conductive member having substantially the same length.

Method for making antenna of coaxial cable and the antenna so made

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.

Electrical connector

An extender (10) comprises a first, male section (12) and a second, female section (14) adapted to be back-to-back assembled. A pair of latches devices (39, 52) are provided on both opposite ends of the male section (12) and female section (14) for fastening the male section (12) and the female section (14) together. A plurality of first passageways (32) are formed in the male section (12) and a corresponding number of second passageways (58) are formed in the female section (14) wherein each of the first passageways (32) cooperates with the aligned corresponding second passageway (58) to form a contact receiving passage for receiving a corresponding contact (80) therein. A pair of grounding tangs (70) are disposed at two opposite ends of the extender (10) wherein each grounding tang (70) comprises an outward facing first portion (72) positioned in the male section (12), and an inward facing second portion (74) positioned in the female section (14). Therefore, the female section (14) of the extender (10) can be coupled to the male connector mounted on the hard drive and the male section (12) of the extender (10) can be coupled to the female connector mounted on the backplane for cooperatively electrically connecting the hard drive to the backplane.

Extender for use with computer internal structure

An electrical connector (10) includes an insulative housing (12) with a plurality of contacts. Adjacent either end of the housing (12) a boardlock (20) and a post (40) are arranged to be aligned with each other in a front-to-end direction. The boardlock (20) generally includes a first vertical section (22) for engagement with the corresponding grounding tang of a complementary connector, and a second vertical section (24) with the downward extending retention legs (25) for extending through a first corresponding hole (102) in the PC board (100), and an upward guiding tab (26). The post (40) includes a horizontal section (42) for retaining the post (40) within the housing (12), and a vertical lug section (46) for extending through a second corresponding hole (104) in the PC board (100).

Boardlock and aligned post of horizontal connector

A connector (10) includes a housing (12) defining a plurality of passageways (16) for receiving a corresponding number of contacts therein. The housing (12) further includes three projection bars (20) extending rearward from a rear surface (18) of the housing (12) for protectively accommodating the corresponding plural contact tails therebetween. A mounting device (22) includes a pair of individual mounting ears (24, 24') which are relatively closely side by side positioned within two juxtaposed slots (38, 38') of the housing (12) wherein each mounting ear (24, 24') has a retention section (28, 28') interferentially embedded within a retention slit (44, 44') for fastening the mounting ear (24, 24') to the housing (12), and an L-shaped mounting section (32, 32') closely beside one side surface (36, 36') of the bar (20). These two mounting ears (24, 24') are compactly and closely arranged to be side by side positioned with each other and also spaced away from each other by a thin divider wall (42) of the housing (12). These two mounting ears (24, 24') are of a pair of mirror images with each other so that the two L-shaped mounting sections (32, 32') of the two mounting ears (24, 24') can respectively abut against two opposite side wall surface (36, 36') of each bar (20).
