The invention discloses a novel rectangular electric connector, which comprises a plug and a socket. The plug comprises a plug shell, a pin, a
pin insulator, a locking screw I, a locking nut, a spring
washer and a small
washer. The socket comprises a socket shell, a jack
assembly, a jack insulator, a locking screw II and a clamping
retainer ring. The novel rectangular electric connector is small in size and compact in structure. The
metal shell of the electric connector has the anti-mis-
insertion protection function and is provided with a plurality of locking mechanisms. The contact body of the electric connector can be designed in three types, namely a
radio frequency coaxial contact body, a large-current contact body and a low-frequency contact body. In this way, the contact bodies can be mixed according to practical situations, so that different
signal transmission functions can be realized. Multiple
signal transmission functions can be realized through the same connector. The
tail part of the contact body can be designed in four
tail appearance manners according to the actual requirements of customers, namely the printed board dip-
welding type,
welding type, and clamped type. The
tail filling mode is adopted between the insulator and the
metal shell to fix the insulator and the
metal shell. The
interference fit and glue filling manner is adopted between the contact body and the insulator to fix the contact body and the insulator.
