Abstract: A block-out lock and removal key includes a locker and a key. The locker has a hollow housing in a shape corresponding to a socket of a network port for engagement, a locker hole extending through a front portion of the housing and a latch body connecting to a rear portion of the housing. The latch body has a rear section extended upwards toward the front portion of the housing and then downwards to form a displaceable piece parallel with the front portion of the housing with a holding section at a top of the displaceable piece and a block facing toward an inner end of the locker hole. The key has its front section arranged correspondingly to a shape of the locker hole to be inserted therein and rotated for unlocking. An eccentric block is further arranged at the front section of the key correspondingly to the block on the displaceable piece for removing the locker from the socket of the network port in operation.

Abstract: A lock-in device for network cables includes a locker, a holding section, and an elastic seesaw. The locker has a through hole for modular connectors to engage therein and to be removed therefrom and a locker hole parallel to the through hole for a key to be inserted therein; an extended end is arranged at a rear end of the locker hole and a space and a fillister with an inclined surface are arranged adjacent to the locker hole. The holding section is disposed in the space with a first depression facing upward at a front end thereof and a second depression facing downward at a rear end thereof. The elastic seesaw has a positioning portion at a rear end thereof extending upwards and forming an elastic piece abutting the second depression for the holding section to be operated by the elasticity. The device thereby enables simultaneous operation of unlocking and removing.
