1. A method for encasing an electrical unit, comprising:
- connecting the electrical unit to a leadframe;
encasing the electrical unit with a first plastic material for forming an inner molded body, so that a plurality of contacts of the electrical unit project from the inner molded body;
punching the inner molded body out of the leadframe;
connecting at least one first contact and one second contact to a shunt resistor; and
encasing the inner molded body and a portion of the shunt resistor with a second plastic material for forming an outer molded body.

Abstract
A method for encasing an electrical unit includes connecting the electrical unit to a leadframe and encasing the electrical unit with a first plastic material to form an inner molded body, so that a plurality of contacts of the electrical unit project from the inner molded body. The inner molded body is punched out of the lead frame. The method also includes connecting at least one first contact and one second contact to a shunt resistor. The inner molded body is encased with a second plastic material to form an outer molded body.

17. An electrical structural element formed by:
-
connecting an electrical unit to a leadframe; encasing the electrical unit with a first plastic material for forming an inner molded body, so that a plurality of contacts of the electrical unit project from the inner molded body; punching the inner molded body out of the leadframe; connecting at least one first contact and one second contact to a shunt resistor; and encasing the inner molded body and a portion of the shunt resistor with a second plastic material for forming the electrical structural element, wherein the shunt resistor has contact areas project beyond the outer molded body.
