Coupling device for terminals having light-conductive filaments

摘要

The invention relates to a coupling device for connecting the terminals of a pair of light-conductive filaments. The coupling device includes a housing, a clamping elongated member positioned within a recess formed in the housing and having a bore to receive two opposite ends of the terminals to be coupled. The clamping member is formed with two parallel longitudinal extensions. The housing is provided with two grooves each positioned in the region of the recess of the housing and extending transversely to the longitudinal central plane of the recess. Each of the grooves accommodates a plurality of pressure-transmitting elements. The housing is closed at each end thereof with a cup-shaped enclosure threadably mounted on the housing. Upon threading the enclosure onto the housing after the terminal to be connected with the other terminal has been inserted therein the enclosure exerts axial pressure which is transmitted to the pressure-transmitting elements located in each groove which in turn transmit this pressure to the extensions of the clamping member so that the latter clamps the terminals to be connected.
