Abstract
A circuit module for a vehicle ignition lock. The circuit module houses a pair of electrical contacts on either side of a key way for closing a circuit between the contacts and a resistor provided in a key. The circuit module includes a cover and base adapted to be secured to one another for enveloping and securely holding a wire set within the module and for positioning the contacts in proper alignment with the key way. The circuit module is adapted to fit into a cylindrical cavity provided in a bezel of the lock.
Claims19
A circuit module assembly for mounting electrical contacts adapted to be placed on opposite sides of a key way in a lock having a stationary sleeve and a rotatable cylinder in the sleeve, the cylinder including a key way for receiving a key, the key including an electrical component adapted for engaging the electrical contacts and closing a control circuit when the key is fully inserted in the key way, the circuit module assembly comprising:
- a. a flat base having opposite sides and including a key way and a pair of cavities, one cavity formed on each side of the key way in one of said sides, each cavity opening into the key way and adapted for receiving and carrying an electrical contact which communicates with the key way in the base;
- b. an electrical wire set having opposite ends, one of said ends received in said base and adapted to be electrically coupled to the electrical contacts and the other of said ends projecting from said base and adapted to be connected to the control circuit;
- c. a cover dimensioned to conform substantially to the base and adapted to be placed in covering relationship with the base for mounting the wire set and the contacts in the base, the cover including a key way in alignment with the key way of said base;
- d. a wire way formed in one side of said base for receiving and preventing movement of said wire set with respect to said base, said wire way communicating at one end with said cavities and at its other end exteriorly of said base;
- e. a bezel mounted on one end of the cylinder and including a cavity dimensioned to receive said base and said cover placed in covering relationship with said base, said bezel and the cylinder having a common key way;
- and
- f. means for mounting said base and said cover placed in covering relationship with said base in said cavity of the bezel.
A vehicle ignition lock having a stationary sleeve, a rotatable cylinder in the sleeve, a bezel mounted on one end of the cylinder, said bezel includes a module-receiving cylindrical cavity formed therein, and said bezel and cylinder including a common key way for receiving a key, said key including an electrical component adapted for engaging a pair of electrical contacts to close a decoder circuit when the key is fully inserted in the key way, a circuit module carrying said electrical contacts so as to be disposed on opposite sides of the key way, and mounting means for snap-fitting said one end of said cylinder to said bezel and simultaneously snap-fitting said circuit module within said cavity between said one end of said cylinder and said bezel.
A circuit module for mounting electrical contacts adapted to be placed on opposite sides of a key way in a lock having a stationary sleeve, a rotatable cylinder in the sleeve and a bezel mounted on one end of the cylinder, the bezel and the cylinder including a common key way for receiving a key, the key including an electrical component adapted for engaging the electrical contacts and closing a control circuit when the key is fully inserted in the key way, the circuit module comprising:
- a. a flat base having opposite sides and including a key way, a push button receiving hole formed therein, and a pair of cavities, one cavity formed on each side of the key way in one of said sides, each cavity opening into the key way and adapted for receiving and carrying an electrical contact;
- b. an electrical wire set having opposite ends, one of said ends received in said base and adapted to be electrically coupled to the electrical contacts and the other of said ends projecting from said base and adapted to be connected to the control circuit;
- c. a cover dimensioned to conform substantially to said base and adapted to be placed in covering relationship with said base for mounting said wire set and the contacts in said base, said cover including a key way in alignment with the key way of said base, and including a push button receiving slot, said push button receiving hole and said push button receiving slot aligned to receive a push button therein;
- and
- d. a wire way including an arcuate shaped long channel formed concavely with respect to the key way of said base, the wire way formed in one side of said base for receiving and preventing movement of said wire set with respect to said base, and said wire way communicating at one end with said cavities and at its other end exteriorly of said base.
