A telephone hook-up box for providing dockside telephone line hook-up to a mating connector plug. The hook-up box incorporates all of the connections necessary for hooking up the telephone lines and the respective line protectors and line continuity checking resistor. The box is formed of a two-piece body and cover portion of molded plastic. The cover is adapted to receive a locking type connector plug with a corresponding mating spring finger contact set disposed in a bore formed in the body element aligned with the cover openings. The spring contacts are integral with three molded-in-place contact-terminal elements which provide the terminal tab portions for both the telephone line and ground hook-ups and connection of the lines to a continuity checking resistor mounted in the body element. The ground contact-terminal elements are also formed with contact seat portions providing a grounding connection to the respective line terminal tab portions. The line protectors are received in threaded bores formed in the body element aligned with the contact seats and with openings in the line terminal tab portions to establish the necessary electrical connections. A hinged spring-biased cover disc is provided to provide a weather-proof closure of the plug connector openings in the box cover.

DETAILED DESCRIPTION In the following detailed description, certain specific terminology will be employed for the sake of clarity and a particular embodiment described in accordance with the requirements of 35 USC 112, but it is to be understood that the same is not intended to be limiting and should not be so construed inasmuch as the invention is capable of taking many forms and variations within the scope of the appended claims.
Referring to FIG.
1, the hook-up box 10, according to the present invention, is particularly adapted to marine, dockside hook-ups in which the hook-up box 10 is mounted to a dock piling 12 adjacent the boatwell for the boat on which the telephone service is to be provided.
The telephone company cable 14, containing the "L1" and "L2" telephone signal lines and the grounding lead are both introduced through the cover opening 16 sealed by means of a rubber grommet 18.
The on-board telephone system is connected to the hook-up box 10 when service is desired by a male locking type plug which is inserted into arcuate openings 20 and central "D" opening 22 formed in the front recess 24 molded in the cover 34.
The front recess 24 is protected by a hinged disc cover 26 which is normally biased into sealing engagement with a pressure ridge 28 mating with a foam material gasket 30 bonded to the inside surface of the hinged disc cover 26.
The hinging is provided by a pair of integral clevises 32, integral with the cover 34, and by a pair of clevises 36 formed on the hinged disc cover 26 with a roll pin 38 providing a pivoting support therefor.
A wind-up spring 40 provides a biasing force urging the hinged disc cover 26 to the closed position.
A lifting tab 42 provides easy grasping of the cover for lifting to the open position and installation of the male connector plug (not shown).
Referring to FIG.
2, the major components of the telephone hook-up box 10 comprise a generally box-shaped body element 44, in addition to the previously mentioned cover 34.
The cover 34 is configured to be slidably received over a shoulder 48 formed about the periphery of the body element 44 and secured thereto by a pair of screws 50 passing through openings 52 formed in the cover 34 and seated in threaded holes 54 on the upper surface 56 of the body element 44
