Exemplary embodiments pertain to the art of electrical wiring and, more particularly, to a termination for a wire bundle.
Electrical conductors are employed to carry electrical current from a source to a load. The electrical current can supply power, control signals, or the like. Electrical conductors are typically covered with insulation that is either removed or penetrated in order to form an electrical connection. In some installations, multiple conductors are bundled and joined by a connector. Before being joined, insulation from each of the conductors must be removed so that all of the conductors are electrically connected.
In high temperature and/or high vibration systems, the insulation surrounding the conductors may be more robust than used in a more conventional installation. The more robust insulation can be very difficult to remove from an underlying conductor. Preparing multiple conductors to be assembled in a bundle and joined through a connector is a very time consuming process. Various techniques including exposure to chemicals or the use of mechanical devices may be used to strip or remove the more robust insulation from the conductors.
A method of electrically connecting a bundle of insulated conductors in accordance with a non-limiting example includes installing an insulation portion of a plurality of electrical conductors into a connector having an axial outer surface. The insulation portion covers an electrically conductive portion. The method further includes exposing a terminal end of each of the plurality of electrical conductors at the axial outer surface, and depositing an electrically conductive material onto the terminal end of each of the plurality of electrical conductors at the axial outer surface of the connector such that the electrically conductive material electrically connects the electrically conductive portion of each of the plurality of electrical conductors.
Additionally, or altematively, in this or other non-limiting examples, the method further includes processing the terminal end of each of the plurality of electrical conductors to be substantially coplanar with the axial outer surface.
Additionally, or altematively, in this or other non-limiting examples, processing the terminal end of each of the plurality of electrical conductors includes machining the terminal end of each of the plurality of electrical conductors and the axial outer surface of the connector.
Additionally, or altematively, in this or other non-limiting examples, depositing the electrically conductive material includes additively manufacturing one or more layers of electrically conductive material onto the axial outer surface of the connector and the terminal end of each of the plurality of electrical conductors.
Additionally, or altematively, in this or other non-limiting examples, depositing the electrically conductive material includes forming a pin end connector with the electrically conductive material.
Additionally, or altematively, in this or other non-limiting examples, depositing the electrically conductive material includes forming a socket connector including an inner wall with the electrically conductive material.
Additionally, or altematively, in this or other non-limiting examples, the method further includes forming a plurality of threads in the inner wall.
A bundled wire electrical connector in accordance with a non-limiting example includes a connector including an outer surface, an inner surface that defines a passage, a first axial end and a second axial end that is opposite the first axial end, and a plurality of conductors arranged in the connector. Each of the plurality of conductors includes an electrically conductive portion having a terminal end and an outer insulating portion surrounding the electrically conductive portion. The outer insulating portion of each of the plurality of conductors is disposed in the passage and the terminal end of each of the plurality of conductors is exposed at one of the first axial end and the second axial end. An electrically conductive material is provided on the one of the first axial end and the second axial end. The electrically conductive material electrically connecting the electrically conductive portion of each of the plurality of conductors.
Additionally, or altematively, in this or other non-limiting examples, the electrically conductive material is deposited onto the one of the first axial end and the second axial end.
Additionally, or altematively, in this or other non-limiting examples, the electrically conductive material forms an electrical connector element on the one of the first axial end and the second axial end.
Additionally, or altematively, in this or other non-limiting examples, the electrical connector element projects axially outwardly of the one of the first axial end and the second axial end.
Additionally, or altematively, in this or other non-limiting examples, the electrical connector element defines a pin connector.
Additionally, or altematively, in this or other non-limiting examples, the electrical connector element defines a socket connector including an inner wall.
Additionally, or altematively, in this or other non-limiting examples, the inner wall is threaded.
Additionally, or altematively, in this or other non-limiting examples, the terminal end of each of the plurality of conductors is substantially co-planar with the one of the first axial end and the second axial end.
