Connection device and connection method for detection of a tension member for an elevator

A connection device for detection of a tension member for an elevator, the tension member configured for suspending an elevator car and/or a counterweight and having a load-bearing portion and a covering layer, the load-bearing portion comprising a plurality of separate load-bearing core wires and being covered by the covering layer, wherein the connection device has a plurality of electrical connection terminals and is configured to be detachably connected to an end portion of the tension member, and respective one ends of the plurality of electrical connection terminals are electrically connected correspondingly to the load-bearing core wires located at the end portion and exposed outwardly and respective other ends of the plurality of electrical connection terminals are used for outward electrical connection, after the connection device is connected to the end portion;

• wherein the connection device comprises:
• a first component having an accommodation portion for accommodating the end portion, wherein the plurality of electrical connection terminals are arranged on the first component;
• and
• a second component detachably connected to the first component and fixing the end portion in place in the accommodation portion;
• wherein the plurality of electrical connection terminals are arranged in parallel, each of which has a first end and a second end, and the first end and the second end are configured to extend toward the load-bearing core wires located at the end portion and the outside of the first component, respectively, after the connection device is connected to the end portion;
• wherein an additional conductive layer having a conductive material is provided in an electrical connection area between the first end and the load-bearing core wire, the conductive material including a conductive adhesive or conductive paste.
