DETAILED DESCRIPTION

[0038] FIG. 1 shows a schematic view of a conductor rail 10. The conductor rail 10 has an electrically conductive conductor rail element 11, which consists of copper, and a sheath 12, which includes a first component 121 made of polypropylene having an elastic modulus of 1300 to 1800 N/mm.sup.2 and a second component 122 made of thermoplastic elastomer, TPE, having an elastic modulus of 8.5 N/mm.sup.2. The sheath 12 is provided along the entire extension or over the entire length of the conductor rail 10, Only the coupling regions, in particular electrical contacting regions 13 are free of the sheath 12. The second component 122 is arranged in first regions 14, which are present at the bends of the electrically conductive conductor rail element 11, and the first component 121 is arranged in second regions 15, which are present at straight sections or planar sections of the electrically conductive conductor rail element 11.

[0039] FIG. 2 shows a schematic sectional view of a first embodiment of a contact surface 16 of the at least one first component 121 and of the at least one second component 122. The contact surface 16 is inclined or a slope, wherein the inclination has an angle of 45°.

[0040] FIG. 3 shows a schematic sectional view of a second embodiment of a contact surface 16 of the at least one first component 121 and of the at least one second component 122. The contact surface 16 is formed in a stepped manner. The stepped formation of the contact surface 16 has a single step.

[0041] FIG. 4 shows a schematic sectional view of a third embodiment of a contact surface 16 of the at least one first component 121 and of the at least one second component 122. The contact surface 16 is formed perpendicularly and straight.

[0042] FIG. 5 shows a schematic view of a method for producing a conductor rail. The method has the following steps: providing at least one electrically conductive conductor rail element and providing an electrically insulating sheath on the at least one electrically conductive conductor rail element. The electrically conductive conductor rail element is provided in a previous step or method by means of a rolling and punching method or application method of a surface coating at least in the connection regions. The electrically insulating sheath is provided by means of an injection molding method on, in particular directly on, the at least one electrically conductive conductor rail element. The electrically insulating sheath is provided by initially providing or arranging an at least one first component, which includes a material having an elastic modulus of greater than or equal to 800 N/mm.sup.2, by means of a first injection molding method on, in particular directly on, regions on which no mechanical stresses act, of the at least one electrically conductive conductor rail. Subsequently, an at least one second component, which includes a material having an elastic modulus of less than or equal to 300 N/mm.sup.2, is provided or arranged by means of a second injection molding method on, in particular directly on, regions on which a mechanical stress acts, of the at least one electrically conductive conductor rail and/or on the at least one first component.

[0045] It will also be understood that, although the terms first, second, etc. are, in some instances, used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the scope of the various described embodiments. The first contact and the second contact are both contacts, but they are not the same contact.

As used in the description of the various described embodiments and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes”, “including”, “includes”, and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0047] As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

[0048] Additionally, while terms of ordinance or orientation may be used herein these elements should not be limited by these terms. All terms of ordinance or orientation, unless stated otherwise, are used for purposes distinguishing one element from another, and do not denote any order of arrangement, order of operations, direction or orientation unless stated otherwise.
