Abstract:
A device for measuring and/or verifying components of optical and/or electrical networks, comprising:a case; an optical and/or electrical connection jack located on the case to which an optical guide and/or electrical lead can be connected directly or indirectly via an adapter; and a lift device with which the connection jack can be adjusted relative to the case between a lifted position and a lowered position, wherein the lift device is equipped with a spring mechanism that pre-tensions the connection jack in the lifted position and with an engaging mechanism that that can be operated by a pressure force in lowering direction and locks into the connection jack in its lowered position, wherein in a first pressure operation the connection jack is moved from its lifted position to its lowered position where the engaging mechanism is engaged, and a subsequent second pressure operation releases the locking of the engaging mechanism so that the spring mechanism moves the connection jack to its lifted position, wherein the engaging mechanism is equipped with a guiding link and an adjustable gliding pin therein, wherein at least one of (i) the gliding pin is stationary with respect to the connection jack, while the guiding link is stationary with respect to the case, or (ii) the guiding link is stationary with respect to the connection jack, while the gliding pin is stationary with respect to the case, wherein the guiding link is equipped with a guiding groove in which the gliding pin locks in and in which the gliding pin moves in an adjustment direction when the connection jack is lifted or lowered, and wherein the guiding groove is designed such that the gliding pin: (a) comes into contact with a first stop in a first lower reversing position, which is lower than the lowered position, when the connection jack is lowered from its lifted position, (b) comes into contact with a lock in its lowered position, located after the first stop with respect to the adjustment direction the gliding pin, when the connection jack is subsequently lifted from this first lower reversing position, (c) comes in contact with a second stop in a second lower reversing position, located after the lock with respect to the adjustment direction of the gliding pin, when the connection jack is subsequently lowered from its lowered position, and (d) passes by the lock and reaches the lifted position when the connection jack is subsequently lifted from this second lower reversing position, wherein redirection mechanisms are provided that ensure that the gliding pin in the guiding groove is moved to the first stop rather than to the second stop when the connection jack is lowered from its lifted position.
