Abstract: A high-speed push-pull self-lock connector includes a first plastic core, a plurality of first terminals, a plurality of second terminals, a first shielding shell, a first housing, and a locking member. The first terminals and the second terminals are disposed through the first plastic core. The first shielding shell covers and is disposed outside the first terminals and the second terminals. The first housing is disposed outside the first plastic core. The first terminals, the second terminals and the first shielding shell are located in the first housing. The locking member has a plurality of locking portions. The locking portions protrude from an inner wall of a base portion of the locking member. The outer wall of the first housing has a plurality of convex portions and a plurality of guiding grooves formed between the convex portions. The locking member is movable to provide a self-locking function.

Abstract: The present invention discloses a patch antenna with an L-shaped cut corner. The patch antenna includes a substrate, a patch, a ground plate and a feed point. The substrate has corresponding first surface and second surface. The patch is installed on the first surface of the substrate. At least one corner of the patch forms the L-shaped cut corner, and two arms of the L-shaped cut corner are disposed at two edges of the patch. The second surface of the substrate includes a ground plate, and the patch includes a feed point for transmitting and receiving feed-in or feed-out wireless signals.
