[0021] The following detailed description and accompanying drawings describe and illustrate various example embodiments of an electrical connector with a shield. The description and illustration of these embodiments are provided to enable those skilled in the art to make and use an electrical connector with a shield according to the present invention. They are not intended to limit the scope of the claims in any way. The present invention can be practiced or implemented in various ways, and the examples described and illustrated herein are merely selected examples of various ways of practicing or implementing the present invention and are not considered to be exhaustive.

[0022] Figures 1 to 10 A first example of an electrical connector 2 having electrical conductors 4 and a housing 6 is shown.

[0023] The electrical conductor 4 has a central axis 7, a conductor top 8, a conductor bottom 10, a conductor body 12, and the conductor body 12 defines a first protrusion 14, a second protrusion 16, a plurality of teeth 18, a first groove 20, and a second groove 22. Each of the first protrusion 14 and the second protrusion 16 extends radially outward from the conductor body 12 and is disposed between the plurality of teeth 18 and the conductor top 8. Each of the plurality of teeth 18 extends radially outward from the conductor body 12 and is disposed between the second protrusion 16 and the conductor bottom 10. The first groove 20 extends from the conductor top 8 to the conductor bottom 10. The second groove 22 extends from the conductor bottom 10 to the conductor top 8. The central axis 7 extends from the conductor top 8 to the conductor bottom 10, passes through the center of the first groove 20, and passes through the center of the second groove 22. As described in more detail herein, the central axis 7 intersects the longitudinal axis 37 of the housing 6. The electrical conductor 4 serves as a conduit for electric current.

[0024] Although the electrical conductor 4 has been illustrated as having a particular structural arrangement, the electrical conductor included in the electrical connector may have any suitable structural arrangement. Selecting a suitable structural arrangement for the electrical conductor included in the electrical connector may be based on various considerations, such as the type of component to which the electrical connector is attached. For example, the electrical conductor may include a single straight-through channel extending from the top of the electrical conductor to the bottom of the electrical conductor. Alternatively, the electrical connector may omit the electrical conductor.

[0025] The electrical conductors may be formed of any suitable material, and the selection of a suitable material may be based on various considerations, such as the intended use of the electrical connector of which the electrical conductors are a component. Examples of materials considered suitable for forming electrical conductors include conductive materials, as well as any other material considered suitable for a particular embodiment.

[0026] The housing 6 is attached to the electrical conductor 4 and has a central axis 25, a first end 26, a second end 28, a first side 30, a second side 32, a top 34, a bottom 36, a longitudinal axis 37, a channel 38, a first groove 40, a second groove 42, a protrusion 44, a flange 46, and a shield 48. The housing 6 is partially disposed above the electrical conductor 4. The first end 26 and the second end 28 are oppositely facing one another. The first side 30 and the second side 32 are oppositely facing one another. The top 34 and the bottom 36 are oppositely facing one another. The longitudinal axis 37 extends from the first end 26 to the second end 28 and intersects the central axis 7. The central axis 25 is disposed in the channel 38 at an angle relative to the longitudinal axis 37. Figures 1 to 10 In the illustrated embodiment, the central axis 25 is disposed orthogonally to the longitudinal axis 37, the central axis 25 is disposed between the first end 26 and the second end 28, and is coaxial with the central axis 7 of the electrical conductor 4. The central axis 25 is disposed a first distance 39 from the first side 30, a second distance 41 from the second side 32, a third distance 43 from the first end 26, and a fourth distance 45 from the second end 28. In the illustrated embodiment, the first distance 39 and the second distance 41 are equal to each other, and the third distance 43 and the fourth distance 45 are equal to each other. However, in alternative embodiments, the first distance and the second distance may be different and / or the third distance and the fourth distance may be different.

[0027] The channel 38 extends from the top 34 to the bottom 36. The electrical conductor 4 is disposed within the channel 38. Each of the first groove 40 and the second groove 42 extends from the channel 38 into the housing 6. The first groove 40 is sized and configured to receive the first protrusion 14 of the electrical conductor 4, and the second groove 42 is sized and configured to receive the second protrusion 16 of the electrical conductor 4. The mating configuration between the first groove 40 and the first protrusion 14 and the mating configuration between the second groove 42 and the second protrusion 16 provide a mechanism for releasably attaching the housing 6 to the electrical conductor 4. A plurality of teeth 18 are disposed within the channel 38 and contact the housing 6 to prevent rotational movement of the housing 6 relative to the electrical conductor 4.

[0028] The protrusion 44 extends from the top 34 of the housing 6 and away from the bottom 36 of the housing 6. In the illustrated embodiment, the protrusion 44 extends partially around the channel 38 and provides a structure for protecting the electrical conductor 4 from the elements during use or for enabling a connection between the housing 6 and another electrical component (e.g., a second electrical connector). Figures 1 to 10 In the example shown, the protrusions 44 are arranged parallel to the central axis 25 of the housing 6. However, in alternative embodiments, the protrusions may have any suitable structural arrangement.

The flange second side 58 has a flange second length 70 extending from the flange first end 64 to the flange second end 66. In the example shown, the flange second length 70 is equal to the flange first length 68. However, in alternative embodiments, the flange first length and the flange second length may be different. The flange first end 64 has a flange first end length 74 extending from the bottom 36 of the shell 6 to the flange bottom 62. The flange second end 66 has a flange second end length 76 extending from the bottom 36 of the shell 6 to the flange bottom 62. Figures 1 to 10In the example shown, the flange second end length 76 is equal to the flange first end length 74. However, in alternative embodiments, the flange second end length and the flange first end length may be different. The flange 46 has a flange third length 78, which is disposed between the flange first end 64 and the flange second end 66. The flange third length 78 extends from the bottom 36 of the housing 6 to the flange bottom 62. In the illustrated embodiment, the flange third length 78 is equal to the flange first end length 74 and the flange second end length 76. However, in alternative embodiments, the flange third length may be greater than, less than, or different from the flange first end length and / or the flange second end length. The flange first side 56 at the flange first end 64 is disposed at a flange first distance 80 from the central axis 25 of the housing 6.

The flange third distance 84 is less than the flange first distance 80 and the flange second distance 82, such that the flange defines a curve 85 between the flange first end 64 and the flange second end 66. The flange 46 is disposed at a flange angle 86 relative to the first side 30 of the housing 6. In the illustrated embodiment, the flange angle 86 is equal to approximately 180 degrees. However, in alternative embodiments, the flange angle may be any suitable angle, such as an angle between 90 degrees and 270 degrees, or any other angle deemed suitable for a particular embodiment.

The shield first end 96 has a shield first end length 106 extending from the shield first side 88 to the shield second side 90. The shield first end 96 is disposed at a first angle 97 relative to the first side 30 of the housing 6. The shield second end 98 has a shield second end length 108 extending from the shield first side 88 to the shield second side 90 and equal to the shield first end length 106. However, in alternative embodiments, the shield second end length and the shield first end length can be different. The shield second side 90 is disposed at a second angle 99 relative to the first side 30 of the housing 6. Each of the first angle 97 and the second angle 99 is greater than 90 degrees. However, in alternative embodiments, the first angle and / or the second angle may be equal to or less than 90 degrees. Figure 5 As shown, the shield second end 98 is disposed on an imaginary plane 101, which is disposed between the top 34 and the flange bottom 62 of the shell 6 and is disposed orthogonal to the central axis 25 of the shell 6. In the illustrated embodiment, the imaginary plane 101 includes the bottom 36 of the shell 6. However, in alternative embodiments, the shield second side can be disposed on any suitable number of imaginary planes, some of which can include the entirety or a portion of the shell bottom. The shield 48 has a shield third length 110 disposed between the shield first end 96 and the shield second end 98, and the shield third length 110 extends from the shield first side 88 to the shield second side 90. Figures 1 to 10 In the example shown, shield third length 110 is less than shield first end length 106 and shield second end length 108. However, in alternative embodiments, shield third length may be equal to or greater than shield first end length and / or shield second end length.

[0033] The shroud first side 88 at the shroud first end 96 is disposed at a shroud first distance 112 from the central axis 25 of the housing 6. The shroud second side 90 at the shroud first end 96 is disposed at a shroud second distance 114 from the central axis 25 of the housing 6. The shroud second side 90 between the shroud first end 96 and the shroud second end 98 is disposed at a shroud third distance 116 from the central axis 25 of the housing 6. In the illustrated embodiment, the shroud first distance 112 and the shroud second distance 114 are different from each other, and the shroud third distance 116 is different from the shroud first distance 112 and the shroud second distance 114. The shroud third distance 116 is greater than the shroud first distance 112 and the shroud second distance 114, such that the shroud 48 defines a curve 117 between the shroud first end 96 and the shroud second end 98.

[0034] The shield 48 is disposed at a shield angle 118 of less than 90 degrees relative to the first side 30 of the housing 6. However, in alternative embodiments, the shield may be disposed at any suitable angle relative to the housing, such as equal to, greater than, or less than 90 degrees, between about 90 degrees and about 1 degree, and any other angle deemed suitable for a particular embodiment. The housing 6 includes the shield 48 disposed at a shield angle 118 of less than 90 degrees to prevent external factors (e.g., rain, salt water) from impacting the electrical connector 4 and the components to which the electrical connector 4 is intended to be connected.

[0035] Although the housing 6 has been illustrated as having a particular structural arrangement, the housing included in the electrical connector may have any suitable structural arrangement. The selection of a suitable structural arrangement for the housing included in the electrical connector may be based on various considerations, such as the type of component to which the electrical connector is attached. The housing may be formed of any suitable material, and the selection of a suitable material may be based on various considerations, such as the intended use of the electrical connector of which the housing is a component. Examples of materials considered suitable for forming the housing include non-conductive materials, plastics, and any other material considered suitable for a particular embodiment.

[0036] Fig.10 The electrical connector 4 is shown attached to a grounding member 120 (e.g., an aluminum surface). As shown, including the shield 48 on the housing 6 increases the overall length of the first creepage path 124, which reduces galvanic corrosion during use. The first creepage path 124 represents the minimum distance traveled along the surface of the housing 6 between the electrical conductor 4 and the grounding member 120. The first creepage path 124 extends from the electrical conductor 4 along the top 34 of the housing 6, along the shield top 92, along the shield bottom 94, and along the flange 46. In addition to the first creepage path 124, Fig.10 The inclusion of shield 48 is shown to result in a disruption in continuity (e.g., by droplets 122) when material 126 (e.g., rain, salt water) moves over shield 48, which also reduces galvanic corrosion during use. The structural features of electrical connector 2, and in particular the inclusion of shield 48, result in an increase in first creepage path 124, increased resistance, and a disruption in continuity of material traveling over electrical connector 4 relative to previous electrical connectors.
