ABSTRACT:
A connecting block (20) which includes a plurality of protectors (30,30) to protect a plurality of incoming communications lines includes a rear panel (28) which is stationary with respect to a housing (25) of the connector block. Mounted in cavities (62, 62) of the rear panel is a mass of contact elements (40,40) arranged in rows and columns and each having a rearwardly extending portion which is connected to a conductor which extend from an associated protector and an opposite portion which extends toward a front panel (60). Mounted in cavities (62,62) of the front panel is a mass of trifurcated contact elements (70,70) each having a base portion (72) and a conductor receiving portion. In a disconnected position, the opposite portion of each contact element is aligned with and overlaps a base (72) of an associated trifurcated contact element with a hook-like portion (46) being spaced from the base of the associated trifurcated contact element by a web (96) of dielectric material in each cavity. The front panel may be moved slidably toward the rear panel to cause the hook-like portion of each contact element to become disposed past the associated web and allow the hook-like portion to engage electrically the aligned, associated trifurcated contact element. As a result, electrical engagement among associated contact elements of two masses of same is affected simultaneously. Disconnection is caused by moving the front panel away from the rear panel to cause a web in each cavity to become interposed between a contact element and its associated trifurcated contact element.
