An FPC connector (10, 10′) comprises a housing (20, 20′) and a pressing member (30, 30′) mounted on the housing rotatable from an open position to a closed position. The housing defines a pair of posts (28a, 28a′) each having a protruding hook (208, 280′) and a pair of notches (24a) each having first and second slanted surfaces (244, 242). A resilient portion (24b) is defined at one side of each notch. The pressing member has a pressing body (32, 32′) having shafts (36a) and L-shaped resilient arms (34a, 34a′). The isolated portions and the first and second slanted facilitate the insertion of the shafts into the notches. The L-shaped resilient arms (34a, 34a′) are provided to engage the protruding hooks of the posts to lock the pressing member at the closed position.

An electrical connector assembly (1) includes a first connector (2) and a second connector (3) engageable with the first connector. The first connector has a first dielectric housing (20) defining a pair of receiving spaces (202), a number of first terminals received in the first housing and a pair of latches (24) retained in the receiving spaces. Each latch includes a retaining portion and a curved spring portion (242) connecting with the retaining portion. The second connector has a second dielectric housing defining a pair of recesses (34) on opposites outer sides thereof and a number of second terminals (32) received in the second dielectric housing. The spring portions of the latch securely engage with the corresponding recess of the second dielectric housing, whereby the first connector stably mates with the second connector.

An electrical connector (1) includes a housing (10), and a plurality of terminals (12, 13) received in the housing. The housing defines side surfaces (1020, 1020′) each forming a plurality of spacers (1022, 1022′). Two adjacent spacers and the corresponding side surface cooperatively define a terminal-passage (1021, 1026) for receiving a terminal therein. Each spacer is formed with at least one retention portion (1023) having a slanted guiding surface (1024) and a positioning surface (1025). The retention portions of each terminal-passage prevent the corresponding terminal from moving between the retention portions and the corresponding side surface. Moreover, two adjacent opposing guiding surfaces of the terminal-passage guide a mating contact of an associated electrical connector until the mating contact is received between two adjacent opposing positioning surfaces of the terminal-passage. Thus the mating contact is securely and reliably received in the terminal-passage.

A dual band slot antenna (1) for an electronic device includes an antenna body (10) with elongated first and second slots (11, 12) defined therein and a coaxial feeder cable (20) having a conductive inner core wire (21) and a conductive outer shield (22). The inner core wire is electrically connected to the antenna body at an outer side of the first slot 11 and the outer shield is electrically connected to the antenna body at an opposite, outer side of the second slot. The coaxial cable acts as a common feed line of the first and second slots.

A surface trimming plane includes a holder, a blade, a press plate, a movable nut, and an adjusting screw. The holder is provided with an inner stepped face which is provided with two tracks, a guide channel and a perforation. The movable nut is mounted in the guide channel. The adjusting screw extends through the perforation, and is screwed through the movable nut. The blade is located between the two tracks and is secured on the movable nut. The press plate is mounted on the holder and located above the blade. The press plate presses the blade to locate the blade. When the adjusting screw is rotated, the movable nut is moved in the guide channel, and the blade is moved with the movable nut to adjust a displacement of the blade.

An electrical connector (100), comprising an insulative housing (1) and a plurality of contacts (2) received in the insulative housing. The insulative housing defines a base portion (11) and a mating portion (12) in front of the base portion, the mating portion defines a plurality of receiving channels (124) extending along a mating direction. The contacts are received in the insulative housing, and inserted into the receiving channels along a front-to-back direction. Each contact has a soldering portion (21) extending through the receiving channel and assembled to the base portion of the insulative housing, a retaining portion (23) located in front of the soldering portion and held in the receiving channel, and a contacting portion (24) received in the mating portion of the insulative housing, the retaining portion has a higher barb (231) in the front and a lower barb (232) on a rear section thereof on both sides.

An electrical connector (1, 2) includes a base (11, 21) having an upper wall (13, 23), a lower wall (14, 24), a pair of connecting walls (136, 236) connecting the upper and lower wall together, and a slot (12, 22) opening frontwardly for receiving a card (4, 5) between the upper wall and the lower wall, the lower wall protruding to the forefront of the connector and forming a pair of supporting portions (19, 29) before the connecting walls, a plurality of terminals (17, 18, 27, 28) retained in the base (11, 21), and a housing portion (130, 131, 230, 231) defined on the upper wall of the base (11, 21), the housing position (130, 131, 230, 231) receiving a protrusion of other connector stacked on the electrical connector (1, 2).
摘要:
An electrical connector (1) comprises an insulative housing (2) with a mating portion (23), a plurality of conductive contacts (4) located in the mating portion and a conductive shielding member (3) encircling the insulative housing. The housing includes a base portion (21) and a pair of guide posts (24) extending from the base portion along a mating direction. Each guide post extends beyond the mating portion. The shielding member includes a substantially rectangular plate (30), a frame (31) extending from the plate for completely encircling the mating portion of the housing and contacting portions (32) corresponding to the guide posts and extending beyond the mating portion for partially surrounding the guide posts. When the electrical connector is mating with a complementary connector, the contacting portion (32) electrically contacts with a conductive member arranged in the complementary connector to cause electrostatic discharge before electrical engagement of the conductive contacts. Thus, the electrostatic discharge may hardly affect the function of the conductive contacts.
