A lock key and a method of its manufacture

Abstract

A lock key, comprising: a key blank (20), including a handle portion (20a) and a key head portion (20b). Housed in a circuit board holder (30) supported by a non-conductive material are: a circuit board (34) mounted with an electrical circuit; and a key contact portion (35) electrically connected to the electrical circuit. The circuit board holder is assembled to the key blank. The placement of the circuit board and the electrical contact conductors in a non-conductive material enables a rational manufacture of the device. It is thus possible to fix the circuit board carrier made of non-conductive material in the key blank, so that the electrical contact conductors can be placed precisely, thereby ensuring a reliable electrical contact function.

Description

technical field

[0001] The present invention relates generally to lock keys, and more particularly to keys for electromechanical locks, the key comprising electrical contact conductors connected to an electronic device carrying the key, the electronic circuitry interacting with the electrical conductors on which the lock is mounted. The invention also relates to a method of manufacturing such a key. Background technique

[0002] Such electromechanical lock devices designed to be operated by means of a key comprising key electronics are known in the prior art. These electronic devices include electronic circuits such as processors and memory circuits mounted on circuit boards. In order to be able to communicate with the corresponding electronics in the lock device, the key contact portion is provided somewhere on the key, preferably on the head of the key. Furthermore, the actual key blank is often used as a ground for the electrical circuit, so that the key electronics are...
