Device for measuring a current flowing in a cable
View Patent ↗An exemplary embodiment relates to a measuring device for measuring a current flowing in a first cable. The measuring device includes a measuring shunt in the form of a plate connected in series with the first cable and associated with a measuring electronic card connected to a data transmission cable. The measuring shunt further includes a measuring portion of resistive alloy coupled to connection portions on either side of the measuring portion. The connection portions are integrally formed with the measuring portion, and the first cable is secured to at least one of the connection portions of the measuring shunt.
1. A system comprising a cable, a battery cable terminal and a measuring device for measuring a current flowing in the cable, the measuring device comprising:
a measuring shunt in the form of a plate connected in series with the cable and associated with a measuring electronic card connected to a data transmission cable, the measuring shunt comprising a measuring portion of resistive alloy connected to connection portions on either side of the measuring portion;
wherein the connection portions are made of resistive alloy integrally with the measuring portion, and the cable has one end secured to one face of a connection portion of the measuring shunt,
wherein the cable end is secured to the corresponding connection portion by autogenous welding,
wherein the connection portion remote from the cable end is secured directly by autogenous welding to a conductive tab integral with the battery cable terminal,
wherein the conductive tab extends perpendicularly to an axis of the battery cable terminal and the conductive tab has a total thickness less than the thickness of the battery cable terminal, and
wherein the measuring shunt includes holes defining the measuring portion of the measuring shunt, and the measuring electronic card includes connection pins engaged in the holes.
