Telephone jack security device

A standard phone jack is provided with a lock cylinder having a rotatable contact arm which is capable of rotating between a first open circuit position when in its locked position and a second closed circuit position where it engages a wire contact to provide access to a dial tone. In such a manner, it completely cuts off all access to the outgoing phone line when locked so that no calls may be made or received by unauthorized users, nor can charge calls or collect calls be accepted by unauthorized users.

What is claimed is:

1. A locking phone jack apparatus having a phone jack assembly, a rotatable lock with a contact arm, a wire contact, a ground wire, a transmission wire carrying a dial tone, a standard phone line receptacle connected to both the transmission wire and the ground wire, and an integral phone jack line connected to the phone jack wherein the rotatable lock is capable of swinging between a first open circuit position while in its locked position to a second closed circuit position when it engages a wire contact hence enabling access to the dial tone.

2. The apparatus according to claim 1 wherein the wire contact is a ground wire contact.

3. The apparatus according to claim 1 wherein the wire contact is a transmission wire contact.

4. The apparatus according to claim 1 wherein the rotatable arm is made of one of the following: aluminum or copper.

5. A locking phone jack apparatus having;

a standard phone jack assembly with a phone jack box cover,

a non-reversible fastener securing the phone jack box cover to the phone jack assembly,

a rotatable lock with a contact arm made from either aluminum or copper, or an alloy of either, with the contact arm further having a ground or transmission wire contact,

a ground wire,

a transmission wire carrying a dial tone,

a standard phone line receptacle connected to both the transmission wire and the ground wire,

an integral phone jack line connected to the phone jack wherein the rotatable arm is capable of swinging between a first open circuit position to a second closed circuit position enabling the apparatus to selectively allow access to and from the dial tone.
