Description

Technical Field

[0001] This disclosure relates to insulated displacement contacts and connection assemblies. Background Technology

[0002] Electrical connectors are typically designed to contact insulated electrical wires, which have a conductive core and an outer insulating layer. Insulated displacement contacts often utilize contact geometry in which the electrical connection with the insulated wire is made at 90°, for example, by a blade cutting through the insulation at a 90° angle to the wire's axis.

[0003] High-volume manufacturing can benefit from reduced assembly steps. This paper discloses an axial insulation displacement contact (IDC) that allows for rapid electrical contact with insulated wires. The axial IDC described herein can, for example, accelerate manufacturing and / or make manufacturing more efficient by reducing assembly steps, and can reduce waste. Summary of the Invention

[0004] This article discloses an axially insulated displacement contact.

[0005] An insulating displacement contact is disclosed, comprising a plurality of guides radially disposed around a receiving axis for receiving the end of a wire along the receiving axis. Each guide includes a blade having a cutting edge for cutting the insulator of the wire along the receiving axis upon receiving the wire; and at least one of a second blade or a spring. Axial IDC can allow for rapid assembly of the connection assembly, for example, eliminating the need for an additional step of stripping the insulator.

[0006] An insulated displacement contact (IDC) is disclosed, comprising a plurality of guides radially disposed around a receiving axis for receiving the end of a wire along the receiving axis. Each guide includes a blade with a cutting edge for cutting the insulation of the wire along the receiving axis upon receiving the wire; and at least one of a rigid opposing feature, a second blade, or a spring. The wire can be cut upon receipt, which can reduce assembly time and / or improve manufacturing efficiency. The guides can be configured to guide, center, and / or receive the wire along the receiving axis. At least one second blade or spring can be configured to press the wire against the blade. When the wire is inserted, the cutting edge can split the insulation of the wire; the cut can expose the radially outer surface of the conductor. The blade can make electrical contact with the conductor of the wire.

[0007] This article discloses a connectivity component that includes an IDC and a line.

[0008] The IDC and / or connectivity components may include the following further improvements and / or embodiments, which may be used individually or in combination independently for further embodiments, unless otherwise stated. The invention is defined by the claims.

[0009] The inward-facing surface of the trailing edge of the blade can contact the conductor of the wire. The inward-facing surface of the trailing edge of the blade can deform the arrangement of the strands within the wire and / or electrically contact a portion of the conductive strands of the wire.

[0010] When viewed along the receiving direction (e.g., the direction in which the wire moves into the IDC), the cutting edge of the blade can be tilted along the receiving direction. The tilt can be towards the receiving axis such that the distance from the receiving axis to the blade, perpendicular to the receiving axis, decreases along the receiving direction. The cutting edge can extend at an angle relative to the receiving axis. The cutting edge can be shaped to allow cutting through the insulation layer and making electrical contact with the wire(s) conductor(s) through the simple operation of inserting the wire into the IDC. The gap between the receiving axis and the blade can be reduced along the receiving direction. The tilt can help center the wire and / or provide appropriate force for cutting and / or deforming the conductors of the wire.

[0011] The blades in an IDC can be configured to plastically deform the surface of the conductor of a wire when the wire has predetermined specifications; and the wire is solid. Blades configured to deform the conductor can help form a robust electrical connection.

[0012] The cutting edge of the blade may have a first angle relative to the receiving axis at the distal portion of the blade and a second angle relative to the receiving axis at the proximal portion of the blade. The first angle is smaller than the second angle. This angle can help center the wire and / or provide appropriate force for cutting and / or deforming the conductor of the wire, and reduce the risk of long-term damage to the wire. The first angle may be an acute angle at the intersection of the first line passing through the cutting edge at the distal portion of the blade and the receiving axis. The second angle may be an acute angle at the intersection of the second line passing through the cutting edge at the proximal portion of the blade and the receiving axis.

[0013] The blade of an IDC may include a following edge that is closer to the receiving axis than the cutting edge. The following edge can be closer to the cutting edge, for example, further along the receiving direction. The following edge geometry can help center the wire and / or provide appropriate force for cutting and / or deforming the conductor of the wire, and reduce the risk of long-term wire damage. The cutting edge may connect two opposing faces of the blade, and the opposing faces may extend radially. The geometry of the opposing faces can help center the wire and / or provide appropriate force for cutting and / or deforming the conductor of the wire. Reliable electrical connection can be provided by the following edge of the blade, such as a following edge closer to the receiving axis than the cutting edge and / or a following edge less sharp than the cutting edge, and / or a following edge including a flat surface facing the receiving axis.

[0014] The following edge can be near the leading edge and is constructed to contact the conductor of the insulated wire; the following edge can connect to the opposite face.

[0015] The blade of the IDC may include a transition from the cutting edge to a flat surface that extends further along the receiving direction than the cutting edge. The flat surface provides a robust electrical connection to the conductor of the wire. The flat surface may face the receiving axis. The flat surface may be located at the proximal end of the cutting edge, opposite the leading edge located at the distal end. The flat surface allows for good electrical contact with the conductor of the inserted wire.

[0016] Each guide in the IDC can have a corresponding nearest point to the receiving axis, and the corresponding nearest points of the guides are evenly distributed at an angle around the receiving axis. The angle can optionally be 180 degrees, 120 degrees, or 90 degrees. This distribution can help to center the wire and / or provide appropriate force for cutting and / or deforming the conductor of the wire.

[0017] The blade may include a pair of opposing faces, each in a plane parallel to the receiving axis. Cutting edges may connect the opposing faces. The cutting edges may face the receiving axis. These faces can help facilitate a clean cut of the insulator with relatively low insertion force. These faces can help provide a predictable amount of plastic deformation of the conductor in the wire, while potentially reducing the risk of wire breakage. The blade may have a planar body extending radially away from the receiving axis, which can help center the wire.

[0018] An insulating displacement contact may have a virtual receiving volume radially defined by the inward-facing surface of a guide, extending along a receiving axis. The receiving axis passes through the center of the virtual receiving volume. The boundary of the receiving volume can help center the wire and / or provide an appropriate amount of plastic deformation of the conductor, while reducing the risk of wire breakage.

[0019] The spring in the IDS is configured to deflect radially away from the receiving axis. The spring can be configured to provide contact force to the wire toward at least one of the receiving axis or the blade. The spring can help center the wire and / or provide appropriate force for cutting and / or deforming the conductor of the wire. The spring may have a rounded surface at its distal end. This can help guide and / or center the wire. The center of curvature of the rounded surface may extend perpendicular to the receiving direction, for example, to optimize wire centering and / or guidance into the IDS.

[0020] The spring can optionally be configured to block the line and provide increased holding force to prevent unintentional line pull-out. For example, the edge of the spring (e.g., the proximal edge) can be used as a barb to prevent the line from being removed axially from the IDC.

[0021] The IDC (Integrated Device Control) may include a backplate located near the blade and perpendicular to the receiving axis. The backplate may structurally support the insertion of the guide and / or limiting line. The backplate and guide may be integral, optionally formed from a sheet metal. This can enhance structural stability and / or improve manufacturing efficiency.

[0022] The IDC may include a housing with an aperture along the receiving axis, located distal to the guide, for receiving the line; the aperture may optionally be circular. The housing helps protect the electrical interface between the line and the IDC. The aperture can help center the line.

[0023] A connection assembly is disclosed, comprising: a wire including an insulator and a conductor; and an insulated displacement contact as described in any embodiment herein. An end of the wire may be along a receiving axis; and a blade may contact the surface of the conductor.

[0024] The insulator may have a cut along the receiving axis at the end of the wire. The surface of the conductor may include a deformation at the end of the wire. The blade may contact the surface of the conductor at the deformation. A proximal flat region of the blade in contact with the surface of the wire may exist. The connection assembly can be assembled efficiently. The connection can be assembled by inserting the wire, for example, without the prior step of stripping the insulation of the wire.

For example, "X, Y and / or Z" means: only X; only Y; only Z; at least X; at least Y; at least Z; only X and Y; only X and Z; only Y and Z; only X, Y and Z; at least X and Y; at least X and Z; at least Y and Z; or at least X, Y and Z. A forward slash " / " can be used to indicate "and / or". For example, "guide / receiver line" can mean guide and / or receive line. In this document, the word "(multiple)" means one or more; for example, (multiple) holes are one or more holes.

[0041] The examples and illustrations described herein are intended to help explain various embodiments of the contact assembly, IDC and its components, such as guides, (multiple) blades and optional (multiple) springs. Detailed Implementation

[0042] Figure 1 A contact assembly according to an embodiment is shown. The contact assembly 300 may include an IDC 200 and a line 110 according to any embodiment described herein.

[0043] IDC 200 may include a plurality of guides 210 arranged radially around a receiving axis 199. The guides 210 may be used to guide / receive the ends 140 of the lines 110 along the receiving axis 199. The ends 140 of the lines 110 may engage with IDC 200.

[0044] The guide 210 may include at least one of a blade 220 and a second blade 222 or a spring 230. (As in...) Figure 1 In the example shown, guide 210 may include blade 220, second blade 222, and spring 230.

[0045] In the contact assembly 300, the wire 110 may be along the receiving axis 199 of the IDC 200. The insulator 120 may include a cut along the receiving axis 199 at an end 140 of the wire 110. The blade 220 may make electrical contact with the conductor 120 of the wire 110, for example, with the surface of the conductor 120. The end 140 of the wire 110 may contact the blade 220, for example, along the longitudinal surface of the wire 110. The conductor 120 may be deformed, for example, at the end 140, which may occur when the wire 110 is received by the IDC 200. Deformation may be advantageous to ensure electrical contact between the conductor 120 of the wire 110 and the IDC 200 (e.g., its blade(s) 200, 222). The blade(s) 220, 222 may contact the surface of the conductor 120 at the deformed location.

[0046] Guide 210 may guide line 110 along receiving axis 199 and / or center line 110. Second blade 222 and / or spring 230 may press line 110 against blade 220, or at least provide a contact force with a component pointing towards blade 220. Spring 230 may provide a contact force to line 110 toward receiving axis 199 and / or blade 220. Spring 230 may deflect away from receiving axis 199. Receiving axis 199 may be collinear and / or parallel to receiving direction 399.

[0047] When wire 110 is received along receiving axis 199, the plurality of blades 220 may split the insulation portion 130 of wire 110. The plurality of blades 220 may expose the radial outer surface of conductor 120 of wire 110 and / or make electrical contact with conductor 120. It is possible that at least one of the guides 210 deforms conductor 120, for example by plastically deforming the outer surface of conductor 120. This may help to form a solid electrical contact.

[0048] Figure 1 A receiving direction 399 is shown, which may be the same as the proximal direction 299. Line 110 may be inserted along the receiving axis 199 in the receiving direction 399 (e.g., proximal) toward IDC 200 to form contact assembly 300. Figure 1 The distal direction 298 is shown in the figure.

[0049] The IDS connector 200 may include a backplate 260. The backplate 260 may be located near the guide 210. The backplate 260 may be perpendicular to the receiving axis 199. The backplate 260 may structurally support the guide 210 and / or the wire 110 upon contact.

[0050] The backplate 260 and guide 210 can be integrally formed, for example, from the same metallic material (such as a sheet metal precursor). The backplate 260 and guide 260 can be formed using a sheet metal, for example, by stamping, cutting, and / or bending. This can simplify manufacturing and / or provide a robust IDC 200.

[0051] IDC 200 allows for rapid assembly of connection component 300, for example, by allowing electrical connection between line 110 and IDC 200 to be achieved simply by inserting line 110. It may not be necessary to separately strip the insulation 130 from line 110.

[0052] Figure 2 A blade for an IDC (Internet Data Center) according to an embodiment is shown. Reference Figure 2 The blades 220a and 220b described herein may represent any one or more blades 220 of any IDC 200 described herein. Figure 2 The receiving direction 399, which can be collinear with the receiving axis 199, is shown.

[0053] One or more blades 220, 222 of the IDC 200 may have a cutting edge 228 for cutting the insulator 130 of the wire 110 along the receiving axis 199 when the wire 110 is received. Each blade 220 may have a cutting edge 228. The blades 220 may make electrical contact with the conductor 120 of the wire 110. Cutting and making electrical contact when the wire 110 is received in the IDC 200 is convenient, for example, to save manufacturing time and / or reduce manufacturing steps to improve efficiency.

[0054] When viewed along the receiving direction 399, the cutting edges 228 of the (multiple) blades can be tilted along the receiving direction 399. For example... Figure 2 As shown, the tilt can be directed toward the receiving axis 199, such that the distances 220r and 220s perpendicular to the receiving axis 199 from the receiving axis 199 to the blade 220 decrease along the receiving direction 399. Figure 2As shown, the first distance 220r, which is farther than the second distance 220s, is greater than the second distance 220s. The cutting edge 228 may extend obliquely relative to the receiving axis 199. Alternatively / additionally, the gap between the receiving axis 199 and the blade 220 may be reduced along the receiving direction 399. A gap may exist between the blades 220 and 222.

[0055] Alternatively / additionally, the distance between blades 220 and 222 can be reduced along the receiving direction 399.

[0056] The blade 220 can be configured to plastically deform the surface of the conductor 120 of the wire 110.

[0057] As in Figure 2 In the example shown, the tilting of the cutting edge 228 and / or the blade 220 can reduce the distances 220r and 220s perpendicular to the receiving axis 199 from the receiving axis 199 to the blade 220 (e.g., the nearest surface of the blade 220) along the receiving direction 399. The tilting can help the guide wire 110 and / or the cutting insulation 130.

[0058] The optional backplate 260 of the IDC 200 is accessible to the cutting edge 228, trailing edge 229, and / or blade 220. The backplate 260 simplifies manufacturing and strengthens the structure. When the backplate 260 and guide 210 are integral, such as when formed from a single sheet of metal, the structure can resist stress and / or is easy to manufacture.

[0059] The receiving axis 199 can be perpendicular to the backplate 260. For example, as in... Figure 3 In this diagram, the receiving axis 199 may be oriented perpendicular to the figure. The receiving axis 199 may be an axis of symmetry of the arrangement of the guides 210, blades 220, 222, 223, and / or their cutting edges 228. For example, the blades 220, 222, 223, and / or their opposing faces 225, 226 may intersect at the receiving axis 199. Alternatively / additionally, the receiving axis 199 may be located at the geometric center of the guides 220 and / or the blades 220, 222, 223. The receiving axis 199 may pass through the midpoint between the two nearest surfaces of the two guides 210, and / or at a point (such as the midpoint) between two guides 210 oriented radially at 180° around the receiving axis 199.

[0060] Figure 3 A cross-sectional view of a contact assembly according to an embodiment is shown. The contact assembly 300 may include an IDC 200 and a line 110. The guide 210 may include inward-facing surfaces 220i, 222i, 223i (e.g., radially inward-facing surfaces).

[0061] The inward-facing surfaces 220i, 222i, 223i (e.g., radially inward-facing surfaces) of the (multiple) blades 220, 222, 223 may contact the conductor 120 of the wire 110. Alternatively / additionally, the inward-facing surfaces 220i, 222i, 223i of the blades 220, 222, 223 may deform the (multiple) conductor strands 120 within the wire 110, for example, by displacing and / or deforming at least one of the conductor strands 120 of the wire 110. Perpendicular to Figure 3 The receiving axis 199 is depicted as x.

[0062] In this document, the inward-facing surfaces 220i, 222i, and 223i may include all or a portion of the trailing edge 229. The inward-facing surfaces 220i, 222i, and 223i may include the proximal portion of the cutting edge 228. The distal portion 228d of the cutting edge 228 may be oriented toward the receiving direction 399, such as... Figure 2 As shown in the example, the farthest portion 228d of the cut edge 228 can be positioned to cut the proximal end face 810 of the insulator 130 (e.g., its radially outward portion) when receiving / inserting the wire 110.

[0063] For example, the inward-facing surfaces 220i, 222i, 223i of the trailing edge 229 may contact the conductor 120 of the wire 110. Alternatively / additionally, the inward-facing surfaces of the trailing edge 229 may deform the arrangement of the strands (e.g., conductor 120) within the wire 110 and / or contact at least a portion of the conductor 120 of the wire 110.

[0064] refer to Figure 2 Note that the blade 220 may include a following edge 229. The following edge 229 may be proximal to the cutting edge 228, for example, immediately adjacent to it. The following edge 229 may be closer to the receiving axis 199 than the cutting edge 228; for example, the nearest surface of the following edge 229 may be closer to the receiving axis 199 than the nearest surface of the cutting edge 228.

[0065] When manufacturing the connecting assembly, the following edge 229 can contact the conductor 120, for example, the wire 110 makes electrical contact with the IDC 200. The cut edge 228 and / or the following edge 229 can deform and / or displace the conductor(s) 120 of the wire 110. For a single solid conductor 120, the cut edge 228 and / or the following edge 229 can deform the surface of the conductor 120, for example, through plastic deformation. This ensures good electrical contact. For a stranded wire 110 having multiple conductors 120, the cut edge 228 and / or the following edge 229 can deform the surface of the conductor 120, for example, through plastic deformation. Alternatively / additionally, at least one of the conductors 120 of the stranded wire 110 can be displaced by the cut edge 228 and / or the following edge 229.

[0066] The blade 220 and / or guide 210 may have a planar body that extends radially away from the receiving axis 199.

[0067] The cutting edge 228 and / or trailing edge 229 can connect two opposing faces 225, 226 of blade(s) 220, 222, 223. Any one or more opposing faces 225, 226 of blade(s) 220, 222, 223 can extend radially, for example, radially away from the receiving axis 199. This can help guide line 110 into IDC 200.

[0068] Alternatively / additionally, each of the opposing surfaces 225, 226 may be parallel to the receiving axis 199. Such an orientation may facilitate a clean cut when line 110 is received and / or help guide line 110 along the receiving axis 199. The opposing surfaces 225, 226 may extend radially, for example, radially relative to the receiving axis 199. Alternatively / additionally, the opposing surfaces 225, 226 may be parallel to each other. Alternatively / additionally, the opposing surfaces 225, 226 may be parallel to the receiving axis 197.

[0069] The receiving axis 199 can be equidistant from at least two guides (e.g., as shown in the image). Figure 3 As shown, for the three guides 210 that serve as blades 220, 222, and 223.

[0070] Follow edge 229 may be located near leading edge 228. Follow edge 229 may be adapted to contact conductor 120 of contact wire 110. Leading edge 228 may be adapted to cut insulator 130, such as end face 133 of insulator 130 and / or along the long axis of insulator 130, such as along receiving direction 199.

[0071] Blade 220 may include a transition from cutting edge 228 to flat surface 229f. Flat surface 229f may be proximal to cutting edge 228. Flat surface 229f (may be at trailing edge 229) may extend further than cutting edge 228 along receiving direction 399. Flat surface 229f may face receiving axis 199, for example, radially inward. Flat surface 229f may be located at the proximal end of cutting edge 228. Flat surface 229f may connect, for example, along the edges of blades 220, 222, 223 facing receiving axis 199 to leading edge 228 located at distal end. Flat surface 229f may be configured to contact the conductor of inserted wire. Flat surface 229f may help provide a strong electrical contact and / or reduce stress on wire 110.

[0072] Figure 4This is a schematic diagram of a blade according to an embodiment. The diagram shows blade 220 and its edge 410 facing the receiving axis 199. The receiving axis 199 may be collinear with the receiving direction 399. A radial direction 470 is shown, for example, radially away from the receiving axis 199.

[0073] The edge 410 of the blade 220 may form a varying angle relative to the receiving direction 399 and / or the receiving axis 199. A first angle 401 of the distal portion 420d of the leading edge 228 of the blade 220 may be greater than a second angle 402 of the proximal portion 420p of the leading edge 228 and / or the proximal portion of the blade 220. The edge 410 may be the leading edge 228.

[0074] The first and second angles can be acute angles, not obtuse angles. For example, the first angle can be the intersection of a first line passing through the cutting edge on the distal portion of the blade and the receiving axis. The second angle can be the acute angle at the intersection of a second line passing through the cutting edge on the proximal portion of the blade and the receiving axis.

[0075] Figure 5 An IDC according to an embodiment is shown. The IDC 200 (such as any IDC 200 described herein) may have guides 210 evenly spaced around a receiving axis 199. Alternatively / additionally, each blade 220, 222, 223, 224 and / or guide 210 of the IDC 200 may have a corresponding nearest point 511, 512, 513, 514 to the receiving axis 199. The corresponding nearest points 511, 512, 513, 514 may be evenly distributed at an angle around the receiving axis 199. For example, the nearest surfaces and / or points 511, 512, 513, 514 of the guides 210 are at 180°, 120°, or 90° around the receiving axis. The evenly spaced guides 210 and / or blades 220, 222, 223, 224 can help guide the line 110 and / or center the line 110. The nearest points 511, 512, 513, and 514 can be radially distributed around the receiving axis 199. The radial distance from the receiving axis 199 to each nearest point 511, 512, 513, and 514 of the blades 220, 222, and 223 can be the same. The radial distance from the receiving axis 199 to each nearest point 511, 512, 513, and 514 of the spring 230 can be the same; and the distance to the optional (multiple) springs 230 can be smaller than the distance to the blades 220, 222, and 223.

[0076] Multiple blades 220 and / or guides 210 may be configured to cause plastic deformation of the surface of the conductor 120 of the wire 110 of a specified size (and / or predetermined size) upon receipt of the wire 110. Alternatively / additionally, multiple blades 220, 222, 223, 224 may cut into the surface of the conductor 120. Multiple blades 220, 222, 223, 224 may be configured to cut into the wire 110 of a specified size at a predetermined depth.

[0077] Alternatively / additionally, the (multiple) blades 220 and / or guides 210 may be configured to deform the arrangement of the strands of the conductor 120 of the wire 110 of a specified specification, for example, when the wire 110 is formed of strands instead of a single solid conductor core.

[0078] For example, the blades 220, 222, 223, 224 can be configured, for example, by arranging the corresponding nearest points 511, 512, 513, 514 of the blades 220, 222, 223, 224 to cut into the line 110 at a depth of approximately 5-10% of the radius of the conductor 120. The radius of the conductor can be determined by a specified wire gauge.

[0079] For example, the blades 220, 222, 223, 224 can be configured to cut into a 4 AWG line 110 having a diameter of 21 mm by arranging the corresponding nearest points 511, 512, 513, 514 of the blades 220, 222, 223, 224. 2 The cross-sectional area of ​​the conductor is 0.13 to 0.26 mm deep, for example, about 5-10% of the radius of conductor 120.

[0080] The nearest points 511, 512, 513, and 514 of the (multiple) blades 220, 222, 223, and 224 may be located at or immediately adjacent to the far end of the (multiple) blades on the flat surface 229f.

[0081] The multiple nearest points 511, 512, 513, 514 of the multiple blades 220, 222, 223, 224 can provide distances from the receiving axis 199 to the corresponding multiple nearest points 511, 512, 513, 514, determined based on the specified wire gauge intended for use in IDC 200. For example, the provided distances can be 80% to 99%, 85% to 98%, or 90% to 97% of the conductor radius of a standard wire gauge.

[0082] The (multiple) blades 220, 222, 223, 224 can be configured such that when forming the conductor assembly 300, for example when the wire 110 is inserted at least to the proximal end of the (multiple) blades 220, the deformed and / or cut portions of the conductor 120 of the wire 110 abut the flat surface 229f of the respective blade 220. The IDC 200 can be designed to receive wires 110 of a specified size, for example, such that the deformed or cut portion abuts the flat surface 229f.

[0083] The multiple blades 220, 222, 223, 224 can be configured such that when the wire 110 is inserted, the multiple blades 220, 222, 223, 224 first cut the proximal end face 810 of the insulator 130, for example at the proximal end face, for example at the radial outermost portion of the proximal end face 810 of the insulator 130.

[0084] The dimensions of the respective nearest points(s) 511, 512, 513, 514 of the blade(s) 220 and / or guide(s) 210 can be determined by the standard line specifications of the IDC 200 design. For example, the specified line specifications by which the IDC 200 is designed to connect to form the electrical assembly 300 can determine the corresponding distance between each of at least two of the nearest points(s) 511, 512, 513, 514 and the receiving axis 199, intercepted along the respective radial direction. The IDC 200 can be designed with the respective nearest points(s) 511, 512, 513, 514 of the blade(s) 220 and / or guide(s) 210, which is suitable for enabling the IDC 200 to specifically form the connector assembly 300 with the specified line specifications.

[0085] For example, the dimensions of the respective nearest points 511, 512, 513, 514 of the blades 220 and / or guides 210 are designed such that when a specified wire gauge is received, the surface of conductor 120 contacts at least one, at least two, or up to all of the blades. The respective nearest points 511, 512, 513, 514 may alternatively / additionally be sized such that when a wire 110 of the specified gauge is received, the surface of conductor 120 undergoes plastic deformation.

[0086] The radial distance from the receiving axis 199 to the nearest points 511, 512, 513, 514 of each blade 220, 221, 222 can be set according to a specified wire gauge (e.g., standard wire gauge). The radial distance can be 1-8%, 2-6%, or 3-5% smaller than the radius of the specified wire gauge. Alternatively / additionally, the radial distance from the receiving axis 199 to the flat surface 229f can be 1-8%, 2-6%, or 3-5% smaller than the radius of the specified wire gauge.

[0087] Alternatively / additionally, as described herein (see [link to article]) Figure 2 The second distance 220s can be designed to ensure electrical contact between at least one of the blades 220 and the conductor 120 of the wire 110. The second distance 220s can be, for example, radially from the flat surface 229f to the receiving axis 199.

[0088] IDC 220 may optionally include spring clip 530. Spring clip 530 may be used to provide another electrical connection, for example, in addition to the connection to line 110. Spring clip 530 may be part of the same integral structure as back plate 260, guide 210 and / or (multiple) blades 220, 222, 223, 224.

[0089] Figure 6 An IDC and line are shown according to an embodiment. Figure 6 An optional housing 610 for IDC 200 and line 110 is shown. Housing 610 can protect the connection from environmental influences. Housing 610 may include a hole 620, which may be circular, for receiving line 110. Hole 620 may be along receiving axis 199 and may facilitate guiding line 110 along receiving axis 199. Hole 620 may be located distal to guide 210. Receiving line 110 through hole 620 and making electrical contact with blade(s) 220 can form contact assembly 300.

[0090] Figure 7 An IDC according to an embodiment is shown. The IDC 200 may have guides 210, which are two or more blades 220, 222. The receiving axis 199 may be along the axis of symmetry of at least two of the two or more guides 210. For two blades 220, 222 arranged radially 180° around the receiving axis 199, the receiving axis may be midway between the blades 220, 222.

[0091] The virtual receiving volume 710 for line 110 may be defined by guides 210 and / or blades 220, 222. Volume 710 may extend along receiving axis 199. Volume 710 may be symmetrical about receiving axis 199. Alternatively / additionally, volume 710 may be radially defined by guides 210 and / or blades 220, 222, 223. Volume 710 may be a cone, pyramid, or a frustum of a cone or pyramid. The narrow end of the cone or pyramid (which may be frustum) may be located proximally, for example, near or adjacent to plate 260. The base of the cone or pyramid may be located distally. Volume 710 may become radially narrower along receiving direction 399. Receiving axis 199 may pass through the center of virtual receiving volume 710. Figure 7Virtual regions 720 and 730 of a virtual receiving volume 710, taken in a plane perpendicular to the receiving axis, are shown, decreasing in size in the proximal direction. The distal region 730 is larger than the proximal region 720. The receiving axis 199 may symmetrically pass through the virtual receiving volume 710, for example, through the center of regions 720 and 730.

[0092] Figure 8 An IDC according to an embodiment is shown. The IDC 200 may have a guide 210, which consists of three blades 220, 222, and 223. A receiving axis 199 may be along the axis of symmetry of at least two of the guides 210. For the three blades 220, 222, and 223 that may be arranged radially 120° around the receiving axis 199, the receiving axis 199 may be the axis of symmetry of the arrangement of the blades 220, 222, and 223.

[0093] Figure 9 An IDS according to an embodiment is shown. Spring 230 can provide a contact force on line 130, the contact force having a component toward the receiving axis 199. The contact force of spring 230 on line 120 can be oriented radially inward. Spring 230 can be offset from the receiving axis 199 and / or provide a contact force toward the receiving axis 199, for example, when line 130 is received along the receiving axis 199. Alternatively / additionally, spring 230 can provide a contact force toward line 110 toward one or more blades 220, 222, 223.

[0094] Spring 230 may have a smooth and / or circular surface 910 at its distal end. Circular surface 910 may be formed by bending in a sheet of metal, for example, a single sheet of metal used to manufacture guide 210 and optional backplate 260.

The receiving axis 199 may be along the axis of symmetry of the distribution of spring 230 and / or blades 220, 222.

[0095] Multiple springs 230 prevent removal. The proximal end of each spring 230 may have a proximal edge 950 that presses against the line 110 and provides a locking force to prevent the line from moving against the receiving direction 399. The proximal edge 950 may be oriented toward the receiving axis 199. The proximal edge 950 may act as a barb and / or a hook, for example, to inhibit removal in the axial direction after the line is in place.

[0096] Figure 10An IDC according to an embodiment is shown. The IDC 200 may have opposing springs 230 and / or opposing blades 220, 222. The opposing springs 230 may be spaced 180° apart and radially distributed about a receiving axis 199. The opposing blades 220, 222 may be spaced 180° apart and radially distributed about a receiving axis 199.

The rigid opposing feature 240 may prevent wire removal after insertion. The rigid opposing feature 240 may include radially inwardly oriented structures, and / or barbs 245 and / or edges. The barbs 245 and / or edges may face the receiving axis and / or proximal direction. The rigid opposing feature 240 may clamp the insulator 130 of the wire 110 after insertion to prevent removal. During insertion, the insulated wire 110 may slide on the rigid opposing feature 240 and / or the radially inwardly oriented structures.

[0098] Alternatively, the rigid relative feature 240 may be in the hole 620 of the housing 610, for example, at the periphery of the hole 620.
