Abstract
Abstract An improved telephone building terminal for use with subscriber-owned equipment. The terminal includes a partition housing including a splice chamber for reception of incoming cable pairs and a second chamber accommodating protector modules and a connector block. Separate covers are hingedly mounted to overlie the splice chamber and the protector and connector chambers. The covers are so arranged that movement of one cover to closed position serves to provide locking means for the other cover whereby only a single padlock is required to prevent unauthorized access to the interior of the housing. Also disclosed is a cable sheath suitable for use in supporting cables of different diameters in openings leading to the splice chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
268 words
Improved sealing means for sealing a generally circular opening in a housing having a main body and an openable cover selectively engaged thereon, said opening being partially formed by a wall of said housing and a wall of said cover when said cover is in at least partially overlapped relation, said means comprising: that part of said opening in said wall of said main body having a first diameter, that part of said opening in said wall of said cover having a second diameter; a generally circular sealing member having a curvilinear side surface, said side surface having a continuous recess therein of stepped cross-sectional configuration to form a plurality of grooves of differing diameter, one of said grooves being of diameter corresponding to that part of said opening in said wall of said main body, and another of said grooves being of a diameter corresponding to that part of said opening formed by said cover; said first and second grooves being laterally spaced from each other a distance corresponding to the degree of overlap upon engagement of said cover with said main body; whereby said sealing member may be simultaneously engaged with said opening with said main body and cover members upon the closing of said cover member upon said said main body; there being a third groove of a diameter common to the groove of larger diameter of said first and second grooves, and symmetrically disposed on either side of said groove of lesser diameter, whereby said sealing member may be positioned in either of two orientations with respect to said main body and said cover.
