Abstract: An electric jack for communication between a mainboard in a telephone network or local area network and a module plug of an external signal line, including a plastic shell, a metal shell covered on the plastic shell to eliminate external electromagnetic interference, a terminal block mounted inside the plastic shell, the terminal block holding a first row of terminals adapted to contact respective terminals on the module plug of the external signal line, and a second row of terminals connected to respective electric contacts on the mainboard, and a filter module mounted in a rear open side of the metal shell and fastened to a back side of the terminal block to eliminate noises from signal passing from the module plug of the external signal line to the mainboard, the filter module having a filter circuit board connected between the first row of terminals and second row of terminals on the terminal block and adapted to eliminate noises from signal passing from the module plug of the external signal line to the

Abstract: A terminal strip packing arrangement including two insulative packing sheets and a terminal strip sandwiched in between the insulative packing sheets and rolled up with them into a roll for storage, wherein the terminal strip has an auxiliary strip integral with linked terminals thereof at one side, the auxiliary strip having outwardly extended protective arms adapted to stop against the insulative packing sheets to protect curved tails of the linked terminals from being compressed by the insulative packing sheets during storage.
