Definitions

  • the invention relates to a wire connector assembly, more particularly, a wire feed-through connector assembly containing provisions that allow use of the wire connector assembly in fluid environments.
  • wire connector assembly includes wire conductors formed with an inner core that has individual wire strands covered by an insulative outer covering. A portion of the wire conductors are stripped free of the insulation covering and the stripped areas are subsequently tinned with solder. Tinning the wire strands fuses the wire strands together by forming a coat of solder on the wire strands resulting in a single, solid core wire connection. The tinned solid core wire connection creates a dam that acts as a leakage barrier to impede fluid flow into, and through the individual wire strands.
  • the tinned solid core connections of the wire conductors are then over-molded with an electrically nonconductive material to form a molded connector body.
  • the molded connector body is subsequently attached to a support structure within the fluid environment.
  • This wire connector assembly design has several drawbacks.
  • One drawback is that the solder may wick into the wire stands so that a tinned portion of the wire strands extend beyond a boundary of the molded connector body. This causes a portion of the wire conductor to be mechanically stiffer than the remaining wire conductor which reduces the flexibility and increases a bend radius of the wire conductor at the molded connector boundary which may inhibit a tight routing path desired in some electrical applications.
  • a wire connector assembly in accordance with one embodiment of this invention, includes a connector body formed of a dielectric material and a plurality of wire cables formed of an electrically conductive inner core surrounded by an electrically insulative outer covering. Each wire cable has an outer covering end portion removed to expose an inner core end portion. Each inner core comprises a plurality of wire strands.
  • the wire connector assembly further includes a wire splice element electrically and mechanically joining at least two inner core end portions. The at least two inner core end portions are axially spaced apart.
  • the connector body encloses the wire splice element and sealably engages each outer covering of the plurality of wire cables.
  • the plurality of wire cables, the wire splice element, and the connector body may provide a fluid resistant electrically conductive path through the wire connector assembly.
  • a portion of the connector body may be disposed intermediate to the at least two inner core end portions to provide a barrier to a fluid infiltrating the inner core of one of the plurality of wire cables.
  • the wire splice element may define a plurality of wire crimp wings.
  • the wire crimp wings may be axially spaced apart.
  • the wire splice element further may define a plurality of insulation crimp wings configured to retain the outer covering.
  • the plurality of insulation crimp wings may be distinct from the plurality of wire crimp wings.
  • a method to fabricate a wire connector assembly includes the step of providing a plurality of wire cables and a wire splice element, wherein the plurality of wire cables are formed of an electrically conductive inner core surrounded by an electrically insulative outer covering.
  • the method further includes the steps of removing the outer covering from an end of each wire cable to expose the inner cores of the plurality of wire cables, inserting the end of each wire cable in the wire splice element, electrically and mechanically attaching the end of each wire cable to the wire splice element to form a wire arrangement, inserting the wire arrangement into a mold, injecting a dielectric material in a fluid state into the mold to surround at least a portion of the wire arrangement containing the wire splice element to form the wire connector assembly, and hardening the dielectric material to a solid state, thereby forming a connector body.
  • the connector body encloses the wire splice element and sealably engages the outer covering of the plurality of wire cables.
  • the wire splice element may define a plurality of wire crimp wings and the step of electrically and mechanically attaching the end of each wire cable to the wire splice element may further include the step of crimping the plurality of wire crimp wings to the end of each wire cable.
  • the wire crimp wings may be axially spaced apart.
  • the step of injecting the dielectric material into the mold may include the step of injecting a portion of the dielectric material intermediate to the end of each wire cable to provide a barrier to a fluid infiltrating the inner core of one of the plurality of wire cables.
  • the wire splice element may further define a plurality of insulation crimp wings configured to retain the outer covering and the step of electrically and mechanically attaching the end of each wire cable to the wire splice element may include crimping the plurality of insulation crimp wings to the outer cover of each wire cable.
  • the plurality of insulation crimp wings may be distinct from the plurality of wire crimp wings.
  • the step of inserting the wire arrangement into the mold may further include the step of arranging a plurality of wire arrangements in the mold so that the plurality of wire arrangements are electrically independent one-to-another.
  • Fig. 1 illustrates a non-limiting example of a wire feed-through connector assembly 10, hereinafter the assembly 10, installed on a lawn mower 12.
  • Assembly 10 is located within a wall 14, or bulkhead 14, of a fuel tank 16 of lawn mower 12 and electrically connects an electrical component (not shown) disposed in fuel tank 16, such as a fuel level sensor, to another electrical component (not shown), such as a fuel gauge, external to fuel tank 16.
  • a gaseous fluid environment 18 e.g. air
  • a second portion 22 of assembly 10 is exposed to a liquid fluid environment 24 (e.g. gasoline).
  • a fluid is defined as a liquid or a gas that is capable flowing when under pressure.
  • assembly 10 is advantageously resistant to leakage of liquid fuel through the assembly 10.
  • Other embodiments of the assembly 10 may be envisioned that are designed to be used in applications where the first and second portions 20, 22 of the assembly 10 are exposed to a gaseous fluid environment 18 or where the first and second portions 20, 22 of the assembly 10 are exposed to a liquid fluid environment 24.
  • the first plurality of wire cables 26a-d and the first portion 20 of assembly 10 are exposed to a gaseous fluid environment 18.
  • the second plurality of wire cables 28a-d and the second portion 22 of the assembly 10 are exposed to a liquid fluid environment 24.
  • Electrical signals are conducted by the first plurality of wire cables 26a-d though the gaseous fluid environment 18, or first environment 18, to a plurality of wire splice elements (not shown) within the connector body 30 and to the second plurality of wire cables 28a-d that conducts the electrical signals though the liquid fluid environment 24 that is a second environment 24 distinctly different from the first environment 18.
  • the first wire cable 26 is mechanically and electrically joined to the second wire cable 28 by a wire splice element 32.
  • Each wire cable is formed of an electrically conductive inner core 34 surrounded by an electrically insulative outer covering 36.
  • Each wire cable has an outer covering 36 end portion removed to expose an inner core 34 end portion.
  • Each inner core 34 is made up of a plurality of wire strands formed of a conductive material, such as a copper alloy or aluminum alloy. Multiple wire strands advantageously allow the wire cables 26, 28 to bend at an interface with connector body 30 without wire cable breakage in contrast to the tinned wire strands in wire feed-through connector assemblies cited in the Background as previously described herein.
  • the outer covering may be formed of a dielectric material, such as polyvinylchloride (PVC), polytetrafluoroethylene (PTFE), or another suitable insulative material well known to those skilled in the art.

  • the first inner core 34 end portion and the second inner core 34 end portion are axially spaced apart.
  • the first inner core 34 end portion and the second inner core 34 end portion are non-axially spaced apart, for example the end portions may be axially offset from each other or the end portions may be arranged perpendicular to each other.
  • the wire splice element 32 defines a plurality of wire crimp wings 40 that are configured to be mechanically and electrically connected to the first inner core 34 end portion and the second inner core 34 end portion.
  • the plurality of wire crimp wings 34 are spaced apart so that when the first and second inner core 34 portion are joined to the wire splice element 32, the first inner core 34 end portion and the second inner core 34 end portion are spaced apart.
  • fluids may enter the wire cables 26, 28 through tears or openings in the outer covering 36 and flow though spaces or voids between the wire strands of the inner core 34. Because the ends of the wire cables 26, 28 are spaced apart, or separated, fluid entering the first wire cable 26 cannot directly continue its flow path to enter the second wire cable 28.
  • wire splice elements 32 having wire crimp wings 34 and the methods used to mechanically and electrically attach wire splice elements 32 to wire cables 26, 28 are well known to those skilled in the art. While this example illustrates a wire arrangement 38 having two wire cables 26, 28 joined by a single wire splice element 32, other embodiments may be envisioned wherein three or more wire cables are joined by a single wire splice element 32.
  • the assembly 10 includes a plurality of wire arrangements 38a-d disposed within a connector body 30 formed of a dielectric material.
  • the connector body 30 encloses the plurality of wire splice elements 32a-d and sealably engages each outer covering 34 of the plurality of the wire cables 26a-d, 28a-d.
  • the connector body 30 of the assembly 10 is sealably attached to the wall 14 of the fuel tank 16 using O-ring seals 42 disposed in grooves in the connector body 30.
  • a portion of the connector body 30 is disposed intermediate to the spaced apart first inner core 34 end portion and the second inner core 34 end portion. The portion of the connector body 30 that is disposed intermediate to the inner core 34 end portions will further inhibit fluid from flowing from the first wire cable 26 into the second wire cable 28 by forming a physical barrier between the first and second inner core ends.
  • the connector body 30 may be formed of a dielectric polymer material, such as polyamide (NYLON) or polybutylene terephthalate (PBT).
  • the connector body 30 may be formed from an epoxy-based dielectric material that chemically bonds with the outer covering 36 of the wire cables 26, 28 and further seals the assembly 10 against fluid leakage entering the assembly 10.
  • the epoxy-based material may provide more robust performance in an application where the assembly 10 will be exposed to chemicals or hydrocarbons because the epoxy-based material is less likely to soften or chemically break down over a time period when disposed these in these types of applications.
  • the wire connector assembly 10 may be useful in the motorized transportation industry such as electrically connecting fuel level sensors in fuel tank applications, or in other industries like chemical processing, or oil and gas exploration where electrical connections must cross a boundary of two different environments.

  • each wire arrangement 38 a-d in the plurality of wire arrangements 38a-d is electrically independent from the other wire arrangements 38 a-d when the wire splice elements 32 a-d are disposed within the connector body 30. While the example of the assembly 10 having wire arrangements with an axial configuration is illustrated, embodiments of the assembly 10 with wire arrangements having non-axial configuration may also be envisioned
  • Figs. 5a and 5b illustrate a non-limiting example of a wire splice element 32.
