An electronic security system for a parking meter. The parking meter housing assembly (200) includes a vault door having a spring-biased contact terminal for making breakable electrical contact with a housing hinge bracket (204a- 204b) contact terminal mounted in a vault opening (203). An electronic lock control circuit is able to communicate with a meter control (coin counting/auditing) circuit in the meter portion of the system through the vault door/housing hinge bracket contact terminals, thus eliminating a direct cable connection between the lock circuit and the meter circuit. The spring- biased contact may be substituted by equivalent breakable electrical contacts such as optocoupler contacts.

L'invention concerne un système de sécurité électronique pour parcmètre. L'ensemble boîtier de parcmètre (200) comprend une porte-forte à borne de contact à ressort, aux fins de contact électrique à rupture avec une borne de contact de patte de charnière de boîtier ((204a-204b) montée dans une ouverture de la chambre forte (203). Un circuit de commande électronique permet de communiquer avec un circuit de commande de mesure (comptage/vérification de pièces de monnaie) dans la partie compteur du système via les bornes de contact de porte-forte/patte de charnière de boîtier, ce qui élimine toute connexion câblée établie directement entre le circuit de verrouillage et le circuit de comptage. Le contact à ressort peut être remplacé par des contacts électriques équivalents à rupture du type contacts à coupleur optoélectronique.
