Description

Electric connection device for electrode

Technical Field

The invention relates to the technical field of electric components, in particular to an electric connection device for an electrode.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

The electrodes are connected through the wires or cables in a common connection mode, and the advantages are that the relative movement between the electrodes caused by cold and hot and mechanical production cannot affect the electric connection, and the defects are that when the electrodes are in a narrow space, the wires or cables with high current occupy space due to the existence of insulating sheaths and can not pass through easily, and particularly when a plurality of electrodes exist in the narrow space, the problems are common.

While the use of conductive metal strips (typically copper material) clamped simultaneously to multiple electrodes, this allows for the connection of multiple electrodes in a confined space and allows for a large current. However, in order to maintain a stable electrical connection, a large contact stress exists between the copper bar and the electrode, and the contact stress is applied to the surface of the electrode usually in a pressure manner, so that the surface of the electrode is easily damaged, and when the electrode structure is soft (such as a thin-walled copper tube), the electrode may deform under the clamping force.

In some scenes, due to cold and hot changes, mechanical structures and the like, certain relative displacement can be generated between the electrode and the metal row, on one hand, additional stress is generated on the electrode to deform the surface and the structure of the electrode, and on the other hand, the contact area is possibly reduced, the contact pressure is smaller, so that the electric contact is deteriorated, and large current cannot be carried.

For example, when the scheme of clamping multiple electrodes by two metal rows is adopted for supplying power to the electric heating rods in rows, after the copper pipe electrode (positive electrode) is deformed due to clamping and relative displacement of the metal rows, the polytetrafluoroethylene insulating layer between the inner part of the copper pipe electrode and the coaxial copper rod negative electrode is thinned under pressure, and the copper pipe electrode is broken down when the voltage is high, so that the electrodes are damaged, and the heating rods are scrapped.

The inner wall of the hole is a conductor, and the hole is internally provided with a closed conductive hole array of elastic electric contact elements, which is the connection mode of most pin-hole combined electric connectors. The disadvantage is that the array of holes does not ensure that each hole is in contact with an electrode for non-parallel rows of electrodes due to the use of closed holes; when there is an obstruction (e.g., protruding insulating sealant) at the end of the electrode, the array of holes is difficult to fit over the appropriate portion of the electrode across the obstruction.
