Definitions

  • the present invention relates to an electrical contact terminal, in particular for use in automotive applications. Particularly, the present invention relates to an electrical contact terminal with a crimp portion. The present invention further relates to a respective method for assembling an electrical contact terminal.
  • These types of electrical connection systems typically comprise an electrical wire having one or a plurality of strands for conducting electrical current and an insulator. To provide for an electrical connection, the strands are crimped to a crimp area of a terminal and said terminal can then be connected to a female connector.
  • an object of the present invention to overcome some or all of the deficiencies of the prior art.
  • the electrical contact terminal should provide for a more flexible crimping and should facilitate employing different sizes of electrical wires. It is a general objective to reduce costs and assembling effort.
  • An aspect of the invention relates to an electrical contact terminal, in particular for use in automotive applications, the electrical contact terminal comprising: a crimp portion for connecting an electrical wire; wherein the crimp portion has a cross-section perpendicular to the longitudinal axis of the crimp portion that has a V-shape, in contrast to e.g. a U-shape.
  • the present disclosure provides an electrical contact terminal that allows for an improved fit, when placed into a connector, for instance in a corresponding connector cavity of a female connector.
  • the crimp portion When the crimp portion is engaged with one or more wire strands of the electrical wire, it has an improved shape such that collision thereof with cavity walls of a connector can be reduced or substantially prevented.
  • This has the advantage that the cavity of the connector does not need to be modified or altered when different electrical wire sizes are crimped and, subsequently, connected with a connector.
  • the electrical contact terminal can hence be employed in various fields of applications whenever an electrical connection between an electrical wire and a connector via a terminal needs to be provided. The flexibility of the electrical contact terminal is thus increased.
  • the "electrical contact terminal” as referred to herein may comprise the electrical wire. However, this may not necessarily be required, as already the electrical contact terminal without the electrical wire provides for the advantages as mentioned in here.
  • the "crimp portion" as referred to herein may be suitable to be subjected to a crimping tool and / or an ultra-sonic welding (USW) as described elsewhere herein.
  • the crimp portion that is comprised by the electrical contact terminal may be understood as a portion of any length along its longitudinal axis.
  • the "electrical wire” as referred to herein may comprise one or more wire strands, which may alternatively be referred to as a conductor. Further, the electrical wire may comprise one or more shielding and / or an insulator. The one or more wire strands of the electrical wire are configured to provide for an electrical connection to another electrically conductive element, such as the crimp portion. In this manner, it is understood that the crimp portion can provide for connecting an electrical wire, i.e., for electrically connecting said electrical wire.
  • the "longitudinal axis" of the crimp portion as referred to herein means that the crimp portion may have a longitudinal shape (which may also be referred to as an elongate shape). This could mean that the crimp portion has a dimension along one axis of the crimp portion, which is larger than one and preferably than both dimensions along the remaining axes of the crimp portion, wherein the remaining axes are substantially perpendicular to said one axis. Thereby, it is understood that the crimp portion merely has one longitudinal axis and not two or more longitudinal axes.
  • the longitudinal axis of the crimp portion may be substantially parallel to the longitudinal axis of the electrical wire.
  • the longitudinal axis of the crimp portion may be substantially coaxial to the longitudinal axis of the electrical wire. The skilled person understands that any electrical wire may have one longitudinal axis, which is easily discernable without detailed investigation.
  • the "longitudinal axis" of the crimp portion may be parallel to a receiving direction of the electrical wire, when the electrical wire is to be engaged with the crimp portion.
  • the "longitudinal axis" of the crimp portion may alternatively be perpendicular to a receiving direction of the electrical wire. The latter may be the case when the electrical wire is brought in engagement with the crimp portion from the top, i.e., along a vertical axis, and when the crimp portion is arranged with its longitudinal axis in a horizontal plane.
  • cross-section of the crimp portion as referred to herein may be understood as the cross-section of the crimp portion, which is filled by a material. Thereby, it may not be a cross-section of the crimp portion that comprises an empty space.
  • the definition of such a cross-section is generally known to the skilled person.
  • the cross-section of the crimp portion being "perpendicular to the longitudinal axis" of the crimp portion means that a normal of the cross-section is substantially parallel to the longitudinal axis of the crimp portion.
  • V-shape of the cross-section of the crimp portion means for instance, that a letter "V” could be recognizable for the skilled person without undue expenditure of investigation. As understood, such a V-shape may have two arms intersecting at an intersecting point.
  • the V-shape has an angle between its two arms of at least 5°, preferably at least 10°, preferably at least 20°, preferably at least 30°, preferably at least 40°, preferably at least 50°, preferably at least 60°, and/or of at most 160°, preferably at most 140°, preferably at most 120°, preferably at most 100°, preferably at most 80°, preferably at most 70°, preferably at most 60°.
  • the angle should not be too small, as this could be detrimental for receiving one or more wire strands of the electrical wire before engaging, e.g., crimping. Further, the angle should not be too large, as this could compromise placement into a connector.
  • the values specified in here provided an optimum compromise between these conflicting requirements.
  • the electrical contact terminal further comprises the electrical wire comprising one or more wire strands, wherein, when crimped, a cross-section of the one wire strand or the plurality of wire strands of the electrical wire engaged with the crimp portion has a triangular shape.
  • the cross-section of the one or more wire strands as referred to herein may be understood as the cross-section, which is filled by a material.
  • the triangular shape of the one or more wire strands may have one or more slightly rounded corners. This may be the case for the corner of the triangular shape that is in contact with the intersecting point of the two arms of the V-shape, as there may be a bending radius present as described elsewhere herein.
  • This embodiment has the advantage that the one or more wire strands substantially adopt the shape of the free space that is provided by the V-shape of the crimp portion.
  • the triangular shape may substantially fill out the V-shape.
  • the triangular shape has an area of at least 1 mm 2 , preferably at least 2 mm 2 , more preferably at least 3 mm 2 , most preferably at least 4 mm 2 , and / or of at most 10 mm 2 , preferably at most 8 mm 2 , more preferably at most 6 mm 2 .
  • the area of the triangular shape may substantially correspond to the area of the one or more strands before crimping. However, minor deviations may occur attributable to plastic deformations of the material or the like.
  • the crimp portion when crimped, maintains its V-shape.
  • the crimp portion does not substantially alter its shape during crimping, as it typically is the case in the prior art.
  • the dimensions of the crimped electrical contact terminal may be easier to predict before crimping.
  • placement of the crimped electrical contact terminal in a connector can be improved. It is appreciated that this applies to any size of the electrical wire.
  • the V-shape has a bending radius between its two arms of at most 1 mm, preferably at most 0.5 mm, more preferably at most 0.4 mm, more preferably at most 0.3 mm, most preferably at most 0.25 mm. It is noted that the bending radius should not be smaller than the thickness of the material, the crimp portion is composed of.
  • a larger bending radius facilitates that the one or more wire strands may be more easily received in the crimp portion before engaging, e.g., crimping.
  • the bending radius should not be too large as this may adversely affect placement of the crimped terminal in a female connector.
  • the values specified in here provide an optimum compromise between these conflicting requirements.
  • the two arms of the V-shape of the crimp portion are not folded around one or more wire strands of the electrical wire, as it typically is the case in the prior art.
  • one or more wire strands of the electrical wire engaged with the crimp portion protrude from the opening of the V-shape to at most 20%, preferably at most 15%, preferably at most 10%, preferably at most 5%, preferably at most 2% of the height of the V-shape.
  • the opening of the V-shape may be defined by a plane connecting the top ends, e.g., the top edges parallel to the longitudinal axis of the V-shape, of the two arms of the V-shape. Since the letter "V" may generally be understood as having only one opening, said V-shape may not have more than one opening.
  • This embodiment has the advantage that the one or more wire strands do not substantially protrude from the opening, thereby, they do not interfere with cavity walls of a female connector.
  • the height of the V-shape is generally understood as the length from the intersecting point of the two arms to the plane connecting the top ends of the V-shape.
  • the length may be measured along an axis that is perpendicular to the plane connecting the top ends of the V-shape.
  • the top surface of the one or more strands may have a structure provided by the crimping tool.
  • the top surface may be the surface opposite to the intersecting point of the two arms of the V-shape.
  • the crimp portion has a plurality of recesses, wherein, when crimped, one or more wire strands of the electrical wire are at least partially pressed into the plurality of recesses.
  • the plurality of recesses facilitates an improved and more secure crimping of the one or more strands and the crimp portion.
  • the recesses may have any suitable shape, in particular, they may have a triangular, rectangular, and / or rhombic shape, which could further facilitate crimping.
  • the recesses of the plurality of recesses are distributed uniformly, preferably uniformly on each of the two surfaces of the crimp portion that has the V-shape.
  • a uniform distribution may also improve manufacturing of the electrical contact terminal.
  • the plurality of recesses are through-holes.
  • the electrical wire comprises an insulator surrounding a part of the one or more wire strands of the electrical wire that is not engaged with the crimp portion, wherein a cross-section of the one or more wire strands of the electrical wire engaged with the crimp portion has a smaller largest dimension than a cross-section of a part of the electrical wire that comprises the insulator.
  • the bottleneck of placement may not be the one or more wire strands of the electrical wire engaged with the crimp portion. Thereby, the bottleneck of placement is independent of the crimping process.
  • the crimped electrical contact terminal may fit into a connector even when the electrical wire is provided with different sizes. This increases flexibility of the electrical contact terminal and reduces costs.
  • the crimp portion is elongate, wherein the elongate part of the crimp portion that is engaged with one or more wire strands of the electrical wire has a length of at least 1 mm, preferably at least 2 mm, preferably at least 4 mm, preferably at least 6 mm, preferably at least 8 mm, preferably at least 10 mm, and/or of at most 30 mm, preferably at most 25 mm, preferably at most 20 mm, preferably at most 18 mm, preferably at most 15 mm.
  • the length should not be too large, as this adversely affects waste of material.
  • the length should be sufficient for substantially fixing the electrical wire to the crimp portion.
  • the crimp portion being elongate may be understood such that at least one dimension is larger than any of the other two dimensions.
  • the other two dimensions may be measured along respective axes that are perpendicular to an axis along which the larger dimension is measured. Hence, one may recognize a longitudinal axis.
  • the length as specified in here may depend on a cross-section of the electrical wire.
  • one or more wire strands of the electrical wire comprises aluminum or copper, wherein the conductor element preferably consists of aluminum or copper, wherein the electrical wire preferably comprises exactly one solid wire strand, wherein the one wire solid strand preferably has a cross sectional area of at least 1 mm 2 , preferably at least 2 mm 2 , more at least 3 mm 2 , most preferably at least 4 mm 2 , and / or of at most 10 mm 2 , preferably at most 8 mm 2 , more preferably at most 6 mm 2 .
  • a further aspect is related to a method for assembling an electrical contact terminal, such as an electrical contact terminal as described elsewhere herein, the method comprising the steps of: providing an electrical wire comprising one or more wire strands; providing a crimp portion for connecting the electrical wire; engaging the crimp portion at least partially with the electrical wire, for establishing an electrical connection therewith; wherein the crimp portion has a cross-section perpendicular to the longitudinal axis of the crimp portion that has a V-shape.
  • the method comprises all advantages of the electrical contact terminal described herein. Particularly, it is noted that the method as described herein may include all aspects and/or embodiments described herein, even if not expressly described as a method but rather with reference to the electrical contact terminal. It is also to be understood that the features and advantages described with reference to the electrical contact terminal may equally be applicable to the method as described herein.
  • engaging comprises crimping and / or welding, preferably ultra-sonic welding the one or more wire strands of the electrical wire to the crimp portion.
  • the crimp portion has a plurality of recesses, wherein engaging comprises pressing the one or more wire strands of the electrical wire at least partially into the plurality of recesses.
