Description

[0001] Electrical connectors are often designed for contact with insulated electrical wires, which have a conductive core and an outer insulating layer. Insulation displacement contacts often use a contact geometry where the electrical connection to the insulated wire is made at a 90° angle; that is, a blade cuts through the insulation at a 90° angle to the axis of the wire.

[0002] High-throughput manufacturing can benefit from reduced assembly steps. This document discloses an axial insulation displacement contact (IDC) that enables rapid electrical contact with an insulated wire. The axial IDC described here can accelerate and / or improve the efficiency of manufacturing, for example, by reducing assembly steps, and can also reduce waste.

[0003] An axial cutting clamp contact is disclosed herein.

[0004] An insulation displacement contact (IDC) is disclosed, comprising a plurality of guides arranged radially around a receiving axis. The guides serve to receive one end of a wire along the receiving axis. The guides include a blade with a cutting edge for cutting an insulator of the wire along the receiving axis as the wire is received, and at least one second blade or a spring. The axial IDC enables rapid assembly of the connection without the need for an additional stripping step.

[0005] An insulation displacement contact (IDC) is disclosed, comprising a plurality of guides arranged radially around a receiving axis. The guides serve to receive one end of a wire along the receiving axis. The guides include a blade that provides a cutting edge for cutting the wire's insulator along the receiving axis as the wire is received, and at least one rigid counterpart, a second blade, or a spring. The wire can be cut during reception, which can reduce assembly time and / or increase manufacturing efficiency. The guides can be configured to guide, center, and / or receive the wire along the receiving axis. The at least one second blade or spring can be configured to press the wire toward the blade. The cutting edge can split the wire's insulation upon insertion; the cut can expose a radially outer face of the conductor.The blade can make electrical contact with the conductor of the wire.

[0006] A connection arrangement comprising the IDC and a wire is disclosed herein.

[0007] The IDC and / or the connection arrangement may include the following further developments and / or embodiments, which, unless otherwise specified, can be combined independently of one another, individually or multiple times, for further embodiments. The invention is defined by the claims.

[0008] The inward-facing surface of the blade's trailing edge can contact the wire conductor. This inward-facing surface can deform the strand arrangement within the wire and / or cause electrical contact with a portion of the wire's conductive strands.

[0009] When viewed along a recording direction (e.g., the direction in which the wire is moved into the IDC), the cutting edge of the blade may be inclined along that direction. The inclination may be in the direction of the recording axis, such that the distance perpendicular to the recording axis from the recording axis to the blade decreases along the recording direction. The cutting edge may extend obliquely to the recording axis. The cutting edge may be shaped to allow cutting the insulation and making electrical contact with the conductor(s) of the wire simply by inserting the wire into the IDC. The distance between the recording axis and the blade may decrease along the recording direction. The inclination may help to center the wire and / or provide a suitable force for cutting and / or deforming the conductor of the wire.

[0010] The blade of the IDC can be designed to plastically deform the surface of a conductor, provided the wire has a predetermined diameter and is solid. Blades designed to deform the conductor can help create a robust electrical connection.

[0011] The cutting edge of the blade can have a first angle with respect to the receiving axis at a distal section of the blade and a second angle with respect to the receiving axis at a proximal section of the blade. The first angle is smaller than the second angle. These angles can help to center the wire and / or provide an appropriate force for cutting and / or deforming the conductor of the wire, reducing the risk of long-term damage to the wire. The first angle can be the acute angle at the intersection of a first line running along the cutting edge at the distal section of the blade and the receiving axis. The second angle can be the acute angle at the intersection of a second line running along the cutting edge at the proximal section of the blade and the receiving axis.

[0012] The IDC blade can have a trailing edge that is closer to the receiving axis than the cutting edge. The trailing edge can be located proximal to the cutting edge, for example, further along the receiving direction. The geometry of the trailing edge can help center the wire and / or provide an appropriate force for cutting and / or deforming the wire conductor, reducing the risk of long-term damage to the wire. The cutting edge can connect two opposite sides of the blade, and these opposite sides can extend radially. The geometry of these opposite sides can also help center the wire and / or provide an appropriate force for cutting and / or deforming the wire conductor.A reliable electrical connection can be established by the trailing edge of the blade, for example by a trailing edge that is closer to the receiving axis than the cutting edge, and / or a trailing edge that is less sharp than the cutting edge, and / or a trailing edge that has a flat surface oriented towards the receiving axis.

[0013] The trailing edge can be located proximal to the leading edge and designed to touch a conductor of an insulated wire; the trailing edge can connect the opposite sides.

[0014] The blade of the IDC can have a transition from the cutting edge to a flat surface that is located further away in the direction of capture than the cutting edge. This flat surface can establish a robust electrical connection to the wire conductor. The flat surface can be oriented towards the axis of capture. The flat surface can be located at a proximal end of the cutting edge, opposite the leading edge, which is located at a distal end. The flat surface can create good electrical contact with the conductor of the inserted wire.

[0015] Each guide of the IDC can have a point closest to the pickup axis, and the respective nearest points of the guides are evenly spaced at angles around the pickup axis. The angles are optionally 180, 120, or 90 degrees. Such a distribution can help to center the wire and / or provide an appropriate force for cutting and / or deforming the wire conductor.

[0016] The blade can have a pair of opposing sides, each lying in a plane parallel to the receiving axis. The cutting edge can connect the opposing sides. The cutting edge can be oriented towards the receiving axis. The sides can help to facilitate a clean cut of the insulator with a relatively low insertion force. The sides can help to produce predictable plastic deformation of the wire conductor and, if necessary, simultaneously reduce the risk of wire breakage. The blade can have a flat body extending radially away from the receiving axis, which can help to center the wire.

[0017] The insulation displacement contact can have a virtual receiving volume, radially bounded by inwardly facing sides of the guides and extending along the receiving axis. The receiving axis passes through the center point of the virtual receiving volume. The boundaries of the receiving volume can help to center the wire and / or achieve adequate plastic deformation of the conductor while reducing the risk of wire breakage.

[0018] The spring of the IDS is designed to bend radially away from the receiving axis. The spring may be designed to exert a contact force on the wire in the direction of at least the receiving axis or the blade. The spring may help to center the wire and / or provide a suitable force for cutting and / or deforming the wire conductor. The spring may have a rounded surface at its distal end. This may help to guide and / or center the wire. A center of curvature of the rounded surface may extend perpendicular to the receiving direction, for example, to optimize the centering and / or guiding of the wire in the IDC.

[0019] The spring can optionally be designed to block the wire and provide increased holding force to prevent unintentional wire withdrawal. For example, an edge, such as a proximal edge, of the spring can act as a barb to prevent axial wire withdrawal from the IDC.

[0020] The IDC can have a backplate positioned proximal to the blade and perpendicular to the receiving axis. The backplate can provide structural support for the guides and / or limit wire insertion. The backplate and guides can be monolithic and optionally machined from a single metal sheet. This can improve structural stability and / or increase manufacturing efficiency.

[0021] The IDC can include a housing with a hole for receiving the wire, distal to the guides along the receiving axis; the hole can optionally be circular. The housing can help protect the electrical interface between the wire and the IDC. The hole can help center the wire.

[0022] A connection arrangement is disclosed comprising a wire with an insulator and a conductor, as well as the insulation displacement contact described herein in any embodiment. One end of the wire may run along the receiving axis, and the blade may be in contact with a surface of the conductor.

[0023] The insulator may have a notch along the receiving axis at the end of the wire. The conductor surface may have a deformation at the wire end. The blade may be in contact with the conductor surface at the deformation. There may be a proximal flat area of ​​the blade that is in contact with the wire surface. The connection assembly can be efficiently assembled. It is possible to assemble the connection by inserting the wire, for example, without a prior stripping step.

[0024] In this context, "and / or" means at least one of the listed elements. For example, "A and / or B" means: only A; only B; at least A; at least B; or at least A and B. For example, "X, Y and / or Z" means: only X; only Y;

[0025] 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 express “and / or.” For example, “a guide guides / accompanies a wire” can mean that the guide guides and / or accommodates a wire. Here, an “()” at the end of a word means one or more; for example, a hole (holes) is one or more holes.

[0026] The following descriptions of embodiments are illustrated with the aid of figures to facilitate understanding. In the figures, elements that correspond in terms of structure and / or function are marked with the same reference symbols.

[0027] The combinations of features shown and / or described in the individual embodiments serve only for illustrative purposes. As explained above, a feature of an embodiment may be omitted if its technical effect is not important for a particular application. Conversely, as explained above, a further feature may be added to an embodiment if its technical effect is advantageous or necessary for a particular application.

[0028] Several examples are described below.

[0029] In the illustrations: Fig. Figure 1 shows a contact arrangement according to embodiments; Fig. 2 shows blades of an IDC according to embodiments; Fig. Figure 3 shows a cross-section of a contact arrangement according to embodiments; Fig. Figure 4 shows a schematic representation of a blade according to embodiments; Fig. Figure 5 shows an IDC according to embodiments; Fig. Figure 6 shows an IDC and a wire according to embodiments; Fig. 7 shows an IDC according to embodiments; Fig. Figure 8 shows an IDC according to embodiments; Fig. Figure 9 shows an IDC according to embodiments; Fig. Figure 10 shows an IDC according to one embodiment; and Fig. Figure 11 shows a cross-sectional view of an IDC according to one embodiment.

[0030] The examples and illustrations described herein serve to explain various embodiments of the contact arrangement, the IDC and its components, such as the guides, blade(s) and optional spring(s).

[0031] Fig. Figure 1 shows a contact arrangement according to one embodiment. A contact arrangement 300 can comprise an IDC 200 according to any embodiment described herein and a wire 110.

[0032] An IDC 200 can have a plurality of guides 210 arranged radially around a receiving axis 199. The guides 210 can serve to guide / receive one end 140 of a wire 110 along the receiving axis 199. The end 140 of the wire 110 can engage with the IDC 200.

[0033] The feedthroughs 210 can have a blade 220 and at least one second blade 222 or a spring 230. As in the Fig. In the example shown, the feedthroughs 210 can include the blade 220, a second blade 222 and a spring 230.

[0034] In the contact arrangement 300, the wire 110 can run along a receiving axis 199 of the IDC 200. The insulator 120 can have a notch along the receiving axis 199 at the end 140 of the wire 110. The blade 220 can be in electrical contact with the conductor 120 of the wire 110, e.g., in contact with the surface of the conductor 120. The end 140 of the wire 110 can make contact with the blade 220, e.g., along the longitudinal surface of the wire 110.

[0035] The conductor 120 may be deformed, for example at the end 140, which can occur when the wire 110 is picked up by the IDC 200. The deformation can be advantageous to ensure electrical contact between the conductor 120 of the wire 110 and the IDC 200, for example its blade(s) 220, 222. The blade(s) 220, 222 can be in contact with the surface of the conductor 120 at the deformation. The guides 210 can guide and / or center the wire 110 along the receiving axis 199.

[0036] The second blade 222 and / or the spring 230 can press the wire 110 towards the blade 220 or at least exert a contact force that has a component in the direction of the blade 220. The spring 230 can exert a contact force on the wire 110 in the direction of the receiving axis 199 and / or the blade 220.

[0037] The spring 230 can deflect away from the receiving axis 199. The receiving axis 199 can be collinear and / or parallel to the receiving direction 399.

[0038] The blade(s) 220 can split the insulation 130 of the wire 110 when the wire 110 is picked up along the receiving axis 199. The blade(s) 220 can expose a radially outer surface of a conductor 120 of the wire 110 and / or create an electrical contact with the conductor 120. It is possible that at least one of the guides 210 deforms the conductor 120, e.g., by plastic deformation of the outer surface of the conductor 120. This can help to establish a robust electrical contact.

[0039] Fig. Figure 1 shows a receiving direction 399, which can be the same direction as the proximal direction 299. A wire 110 can be inserted along the receiving axis 199 in the receiving direction 399 (e.g., proximal) in the direction of the IDC 200 to create the contact arrangement 300. A distal direction 298 is shown in Fig. 1 shown.

[0040] The IDS connector 200 can have a backplate 260. The backplate 260 can be arranged proximal to the guides 210. The backplate 260 can be perpendicular to the receiving axis 199. The backplate 260 can provide structural support to the guides 210 and / or the wire 110 upon contact.

[0041] The backplate 260 and the guides 210 can be monolithically formed, e.g., produced from the same metal material, such as a metal plate precursor. A metal plate can be used to form the backplate 260 and the guides 260, e.g., by punching, cutting, and / or bending. This can simplify manufacturing and / or provide a robust IDC 200.

[0042] The IDC 200 enables quick assembly of the connection assembly 300, for example, by creating the electrical connection between the wire 110 and the IDC 200 simply by inserting the wire 110. It is unnecessary to strip the insulation 130 separately from the wire 110.

[0043] Fig. Figure 2 shows blades of an IDC according to embodiments. The in relation to Fig. The blades 220a and 220b described herein may be representative of one or more blades 220 of any IDC 200 described herein. Fig. Figure 2 shows the recording direction 399, which can be collinear with the recording axis 199.

[0044] One or more blades 220, 222 of an IDC 200 can have a cutting edge 228 for cutting an insulator 130 of the wire 110 along the receiving axis 199 when the wire 110 is received. Each blade 220 can have a cutting edge 228. The blade(s) 220 can establish electrical contact with the conductor 120 of the wire 110. It is advantageous for the cutting and electrical contact to be established when the wire 110 is inserted into the IDC 200, for example, to save manufacturing time and / or reduce manufacturing steps to increase efficiency.

[0045] When viewed along the recording direction 399, the cutting edge 228 of the blade(s) can be inclined along the recording direction 399. The inclination can be, as shown in Fig. 2, as seen, in the direction of the recording axis 199, such that a distance 220r, 220s, perpendicular to the recording axis 199, from the recording axis 199 to the blade 220 decreases along the recording direction 399. As in Fig. As can be seen in Figure 2, there is a first distance 220r, which is more distal to the second distance 220s and larger than the second distance 220s. The cutting edge 228 can extend obliquely with respect to the recording axis 199. Alternatively / additionally, the distance between the recording axis 199 and the blade 220 can decrease along the recording direction 399. There can be a gap between the blades 220 and 222.

[0046] Alternatively / additionally, the distance between the blades 220, 222 can decrease along the recording direction 399.

[0047] The blade 220 can be designed to plastically deform a surface of a conductor 120 of the wire 110.

[0048] As in the Fig. In the example shown, the inclination of the cutting edge 228 and / or the blade 220 can be such that the distance 220r, 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) decreases along the receiving direction 399. The inclination can contribute to guiding the wire 110 and / or cutting the insulation 130.

[0049] The optional backplate 260 of the IDC 200 can be located near the cutting edge 228, the trailing edge 229, and / or the blade 220. A backplate 260 can simplify manufacturing and reinforce the structure. If the backplate 260 and the guides 210 are monolithic, for example, formed from a single metal plate, the structure can be resistant to stress and / or easy to manufacture.

[0050] The mounting axis 199 can be perpendicular to the back plate 260. For example, the mounting axis 199 can be, as in Fig. The receiving axis 199, as shown in Figure 3, can be oriented perpendicular to the figure. It can 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 opposite sides 225, 226 can intersect at the receiving axis 199. Alternatively / additionally, the receiving axis 199 can lie at a geometric center of the guides 210 and / or the blades 220, 222, 223. The receiving axis 199 can pass through a midpoint between the nearest surfaces of two of the guides 210 and / or through a point (e.g., a midpoint) between two guides 210 that are radially oriented 180° around the receiving axis 199.

[0051] Fig. Figure 3 shows a cross-sectional view of a contact arrangement according to one embodiment. A contact arrangement 300 can have an IDC 200 and a wire 110. The guides 210 can have inwardly facing surfaces 220i, 222i, 223i (e.g., radially inwardly facing surfaces).

[0052] An inwardly directed surface 220i, 222i, 223i (e.g., a radially inwardly directed surface) of the blade(s) 220, 222, 223 can contact the conductor 120 of the wire 110. Alternatively / additionally, an inwardly directed surface 220i, 222i, 223i of the blade(s) 220, 222, 223 can deform the strands of the conductor(s) 120 within the wire 110, e.g., by displacing and / or deforming at least one of the strands of the conductor(s) 120 of the wire 110. The receiving axis 199, which is perpendicular to Fig. The number 3 is represented as x.

[0053] Here, an inwardly facing surface 220i, 222i, 223i can comprise all or part of the trailing edge 229. An inwardly facing surface 220i, 222i, 223i can comprise a proximal section of the cutting edge 228. A distal section 228d of the cutting edge 228 can be oriented in the direction of the recording direction 399, as in the example in Fig. 2 shown. The most distal section 228d of the cutting edge 228 can be positioned such that it cuts the proximal end face 810 of the insulator 130 (e.g. a radially outward-facing section thereof) when the wire 110 is picked up / inserted.

[0054] For example, the inward-facing surface 220i, 222i, 223i of the trailing edge 229 can contact the conductor 120 of the wire 110. Alternatively / additionally, the inward-facing surface of the trailing edge 229 can deform the arrangement of the strands (e.g., conductor 120) within the wire 110 and / or contact part of at least one of the conductors 120 of the wire 110.

[0055] Referring to the presentation in Fig. 2. The blade 220 can have a trailing edge 229. The trailing edge 229 can be located proximal to the cutting edge 228, e.g., immediately proximal to it. The trailing edge 229 can be located closer to the receiving axis 199 than the cutting edge 228; for example, the nearest surface of the trailing edge 229 is located closer to the receiving axis 199 than the nearest surface of the cutting edge 228.

[0056] The trailing edge 229 can contact the conductor 120 when a connection arrangement is created, e.g., with a wire 110 that is in electrical contact with the IDC 200. The cutting edge 228 and / or the trailing edge 229 can deform and / or displace the conductor(s) of a wire 110. In the case of a single solid conductor 120, the cutting edge 228 and / or the trailing edge 229 can deform the surface of the conductor 120, e.g., plastically deform it. This can ensure good electrical contact. In the case of a stranded wire 110 with multiple conductors 120, the cutting edge 228 and / or the trailing edge 229 can deform the surface of the conductor 120, e.g., plastically deform it. Alternatively / additionally, at least one of the conductors 120 of a stranded wire 110 can be moved by the cutting edge 228 and / or the trailing edge 229.

[0057] The blade 220 and / or the guides 210 can have a flat body that can extend radially away from the receiving axis 199.

[0058] The cutting edge 228 and / or the trailing edge 229 can connect two opposite sides 225, 226 of the blade(s) 220, 222, 223. The opposite sides 225, 226 of one or more of the blades 220, 222, 223 can extend radially, e.g., radially away from the receiving axis 199. This can help guide the wire 110 into the IDC 200.

[0059] Alternatively / additionally, each of the opposing sides 225, 226 can run parallel to the receiving axis 199. Such an orientation can help promote a clean cut when the wire 110 is picked up and / or help facilitate the guiding of the wire 110 along the receiving axis 199. The opposing sides 225, 226 can extend radially, e.g., radially with respect to the receiving axis 199. The opposing sides 225, 226 can alternatively / additionally be parallel to each other. Alternatively / additionally, the opposing sides 225, 226 can be parallel to the receiving axis 199.

[0060] The receiving axis 199 can be equidistant from at least two guides (e.g., as in Fig. 3 in the three guides 210, which are the wings 220, 222, 223).

[0061] The trailing edge 229 can be located proximal to the leading edge 228. The trailing edge 229 can be configured to contact the conductor 120 of the wire 110. The leading edge 228 can be configured to cut the insulator 130, e.g., an end face 133 of the insulator 130 and / or along the longitudinal axis of the insulator 130, e.g., along the receiving direction 199.

[0062] The blade 220 can have a transition from the cutting edge 228 to a flat surface 229f. The flat surface 229f can be located proximal to the cutting edge 228. The flat surface 229f, which can be located at the trailing edge 229, can be located further along the receiving direction 399 than the cutting edge 228. The flat surface 229f can be oriented towards the receiving axis 199, e.g., radially inward. The flat surface 229f can be located at a proximal end of the cutting edge 228. The flat surface 229f can be connected to the leading edge 228, which is located at a distal end, e.g., along an edge of the blade 220, 222, 223 facing the receiving axis 199. The flat surface 229f can be configured to contact the conductor of the inserted wire. The flat surface 229f can help to establish a robust electrical contact and / or reduce the stress on the wire 110.

[0063] Fig. Figure 4 is a schematic representation of a blade according to one embodiment. The schematic representation shows a blade 220 and an edge 410 of the blade 220, which faces the receiving axis 199. The receiving axis 199 can be collinear with the receiving direction 399. A radial direction 470 is shown, e.g., radially away from the receiving axis 199.

[0064] The edge 410 of the blade 220 can form a varying angle with respect to the recording direction 399 and / or the recording axis 199. A first angle 401 of a distal section 420d of the front edge 228 of the blade 220 can be greater than a second angle 402 of a proximal section 420p of the front edge 228 and / or of a proximal section of the blade 220. The edge 410 can be the front edge 228.

[0065] The first and second angles can be acute angles instead of obtuse angles. For example, the first angle can be the intersection of a line running along the cutting edge on the distal part of the blade and the recording axis. The second angle can be the acute angle at the intersection of a line running along the cutting edge on the proximal part of the blade and the recording axis.

[0066] Fig. Figure 5 shows an IDC according to one embodiment. An IDC 200, such as any IDC 200 described herein, can have guides 210 arranged uniformly around the receiving axis 199. Alternatively / additionally, each blade 220, 222, 223, 224 and / or guide 210 of the IDC 200 can have a respective nearest point 511, 512, 513, 514 to the receiving axis 199. The respective nearest points 511, 512, 513, 514 can be evenly distributed at angles around the receiving axis 199. For example, the nearest surfaces and / or points 511, 512, 513, 514 of the guides 210 are located at an angle of 180°, 120°, or 90° around the receiving axis. Evenly spaced guides 210 and / or blades 220, 222, 223, 224 can assist in guiding and / or centering the wire 110. The nearest points 511, 512, 513, 514 can be distributed radially around the receiving axis 199.The radial distances from the mounting axis 199 to each of the nearest points 511, 512, 513, 514 of the blades 220, 222, 223 can be equal. The radial distances from the mounting axis 199 to each of the nearest points 511, 512, 513, 514 of the springs 230 can be equal; and the distances to optional springs 230 can be smaller compared to the distances to the blades 220, 222, 223.

[0067] The blade(s) 220 and / or guides 210 can be designed to cause plastic deformation of the surface of the conductor 120 of a wire 110 of a specific wire diameter (and / or a predetermined wire diameter) when the wire 110 is inserted. Alternatively / additionally, the blade(s) 220, 222, 223, 224 can cut into the surface of the conductor 120. The blade(s) 220, 222, 223, 224 can be designed to cut into the wire 110 of a specific wire diameter to a predetermined depth.

[0068] Alternatively / additionally, the blade(s) 220 and / or guides 210 can be designed to deform the arrangement of the strands of the conductor 120 of a wire 110 of a certain wire thickness, e.g. if the wire 110 is formed with strands instead of a single solid conductor core.

[0069] For example, the blade(s) 220, 222, 223, 224 can be configured by arranging the respective nearest points 511, 512, 513, 514 of the blade(s) 220, 222, 223, 224 to cut into a wire 110 to a depth of approximately 5-10% of the radius of the conductor 120. The radius of the conductor can be determined based on the specified wire diameter.

[0070] For example, the blade(s) 220, 222, 223, 224 can be designed by configuring the respective nearest points 511, 512, 513, 514 of the blade(s) 220, 222, 223, 224 such that they are connected to a wire 110 with 4 AWG and a conductor cross-sectional area of ​​21 mm² 2 Cut to a depth of 0.13 to 0.26 mm, i.e. about 5 to 10% of the radius of the conductor 120.

[0071] The nearest point(s) 511, 512, 513, 514 of the blade(s) 220, 222, 223, 224 may be located on the flat surface 229f of the blade(s) or immediately distal to it.

[0072] The nearest point(s) 511, 512, 513, 514 of the blade(s) 220, 222, 223, 224 can have a distance from the receiving axis 199, which is determined based on the intended wire gauge for which the IDC 200 is to be used. For example, the intended distance can be 80% to 99%, 85% to 98%, or 90% to 97% of a conductor radius of a standard wire gauge.

[0073] The blade(s) 220, 222, 223, 224 can be configured such that a deformed and / or cut section of the conductor 120 of the wire 110 rests against the flat surface 229f of the respective blade 220 when the conductor arrangement 300 is formed, e.g., when the wire 110 is inserted at least to the proximal end of the blade(s) 220. The IDC 200 can be configured to accommodate a specific diameter of the wire 110, for example, such that the deformation or cut rests against the flat surface 229f.

[0074] The blade(s) 220, 222, 223, 224 can be designed such that when the wire 110 is inserted, the blade(s) 220, 222, 223, 224 first cut the proximal end surface 810 of the insulator 130, e.g. at the proximal end surface, such as at a radially outermost section of the proximal end surface 810 of the insulator 130.

[0075] The nearest points 511, 512, 513, 514 of the blades 220 and / or guides 210 can be dimensioned according to a standard wire thickness for which the IDC 200 is designed. For example, a specific wire gauge to which the IDC 200 is to be connected to form an electrical assembly 300 can determine the respective distances between at least two of the nearest points 511, 512, 513, 514 and the receiving axis 199, measured along the respective radial directions. An IDC 200 can be designed such that the nearest points 511, 512, 513, 514 of the blades 220 and / or guides 210 are adapted so that the IDC 200 forms, in particular, a connector assembly 300 with the intended wire cross-section.

[0076] For example, the respective nearest points 511, 512, 513, 514 of the blades 220 and / or feedthroughs 210 are dimensioned such that, when the intended wire is inserted, the surface of the conductor 120 contacts at least one, at least two, or all of the blades. Alternatively / additionally, the respective nearest points 511, 512, 513, 514 can be dimensioned such that the surface of the conductor 120 is plastically deformed when the wire 110 of the intended diameter is inserted.

[0077] The radial distance from the receiving axis 199 to the nearest point(s) 511, 512, 513, 514 of each blade 220, 221, 222 can be adjusted according to a specific wire (e.g., a standard wire). The radial distance can be 1–8%, 2–6%, or 3–5% smaller than the radius of the intended wire diameter. 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 intended wire diameter.

[0078] Alternatively / additionally, the second interval can be 220s, as described here (see Fig. 2) be designed such that electrical contact between at least one of the blades 220 and the conductor 120 of the wire 110 is ensured. The second distance 220s can be from the flat surface 229f to the receiving axis 199, e.g. along a radial direction.

[0079] An IDC 220 can optionally have a spring clamp 530. The spring clamp 530 can be used to make an additional electrical connection, e.g., in addition to the connection with the wire 110. The spring clamp 530 can be part of the same monolithic structure as the backplate 260, the guides 210, and / or the blade(s) 220, 222, 223, 224.

[0080] Fig. Figure 6 shows an IDC and a wire according to one embodiment. Fig. Figure 6 shows an optional housing 610 for an IDC 200 and a wire 110. The housing 610 can protect the connection from environmental influences. The housing 610 can have a hole 620, which may be circular, to receive the wire 110. The hole 620 can extend along the receiving axis 199 and help guide the wire 110 along the receiving axis 199. The hole 620 can be located distal to the feedthroughs 210. The receiving of the wire 110 through the hole 620 and the electrical contacting of the blade(s) 220 can form the contact arrangement 300.

[0081] Fig. Figure 7 shows an IDC according to one embodiment. An IDC 200 can have guides 210, which are two or more blades 220, 222. The receiving axis 199 can run along an axis of symmetry of at least two of the two or more guides 210. If two blades 220, 222 are arranged radially 180° around the receiving axis 199, the receiving axis can be located midway between the blades 220, 222.

[0082] A virtual receiving volume 710 for the wire 110 can be bounded by the guides 210 and / or the blades 220, 222. The volume 710 can extend along the receiving axis 199. The volume 710 can be symmetrical about the receiving axis 199. Alternatively / additionally, the volume 710 can be bounded radially by the guides 210 and / or the blades 220, 222. The volume 710 can be a cone, a pyramid, or a truncated cone or pyramid. The narrow end of the cone or pyramid, which may be truncated, can be located proximally, e.g., near or beside the plate 260. The base of the cone or pyramid can be located distally. The volume 710 can taper radially along the receiving direction 399. The receiving axis 199 can pass through the center point of the virtual receiving volume 710. Fig. Figure 7 shows virtual areas 720 and 730 of the virtual recording volume 710, which were recorded in planes perpendicular to the recording axis and decrease in size in the proximal direction. A distal area 730 is larger than a proximal area 720. The recording axis 199 can pass symmetrically through the virtual recording volume 710, e.g., through the centers of areas 720 and 730.

[0083] Fig. Figure 8 shows an IDC according to one embodiment. An IDC 200 can have guides 210, which are three blades 220, 222, 223. The receiving axis 199 can run along an axis of symmetry of at least two of the guides 210. With three blades 220, 222, 223, which can be arranged radially by 120° around the receiving axis 199, the receiving axis 199 can be an axis of symmetry of the arrangement of the blades 220, 222, 223.

[0084] Fig. Figure 9 shows an IDS according to one embodiment. A spring 230 can provide a contact force on a wire 110, wherein the contact force has a component in the direction of the receiving axis 199. The contact force of the spring 230 on the wire 110 can be directed radially inwards. The spring 230 can be deflected away from the receiving axis 199 and / or exert a contact force in the direction of the receiving axis 199, e.g., when a wire 110 is received along the receiving axis 199. Alternatively / additionally, the spring 230 can exert a contact force on the wire 110 in the direction of one or more blades 220, 222, 223.

[0085] The spring 230 can have a smooth and / or rounded surface 910 at its distal end. The rounded surface 910 can be formed by bending in a metal sheet, e.g., a monolithic metal sheet used to produce the guides 210 and the optional backplate 260. The rounded surface 910 can have a center of curvature 920 extending perpendicular to the receiving axis 199. The spring 230 can have an inclination 930 when viewed along the receiving direction 399. The receiving axis 199 can run along an axis of symmetry of the distributions of the springs 230 and / or the blades 220, 222.

[0086] The spring(s) 230 can prevent removal. The proximal end of the spring 230 can have a proximal edge 950 that presses against the wire 110 and can provide a locking force to prevent the wire from moving against the receiving direction 399. The proximal edge 950 can be oriented in the direction of the receiving axis 199. The proximal edge 950 can act as a barb and / or be a barb, for example, to prevent removal along the axial direction after the wire has been attached.

[0087] Fig. Figure 10 shows an IDC according to one embodiment. An IDC 200 can have opposing springs 230 and / or opposing blades 220, 222. Opposing springs 230 can be 180° apart and radially distributed around the receiving axis 199. Opposing blades 220, 222 can also be 180° apart and radially distributed around the receiving axis 199. The receiving axis 199 can extend along an axis of symmetry of the distributions of the springs 230 and / or blades 220, 222.

[0088] Fig.Figure 11 shows a cross-sectional view of an IDC according to one embodiment. A guide 210 of an IDC 200 can be a rigid counterpart 240. The rigid counterpart 240 can prevent the wire from being removed after insertion. The rigid counterpart 240 can have a radially inwardly directed structure and / or a barb 245 and / or an edge. The barb 245 and / or the edge can point toward the receiving axis and / or in the proximal direction. After insertion, the rigid counterpart 240 can grip the insulator 130 of the wire 110 to prevent its removal. The insulated wire 110 can be pushed over the rigid counterpart 240 and / or the radially inwardly directed structure during insertion.

[0089] Alternatively, the rigid counterpart 240 can be located in the hole 620, for example on a circumference of the hole 620 of the housing 610.

[0090] The rigid counterpart 240 can be used individually, multiple times and / or in combination with other guides 210, for example blades 220 and / or springs 230.

[0091] In this context, the terms "trailing edge" and "trailing edge" can be used synonymously. Similarly, the terms "leading edge" and "cutting edge" can be used synonymously.

[0092] In this case, the front edge and / or cutting edge can be located distal to the rear edge and / or trailing edge.

[0093] A picked-up wire 110 can initially reach the cutting edge 228 of the blade 220 before being picked up further and reaching the trailing edge 229.

[0094] In this case, "proximal" can be further along the recording direction 399 than "distal". For example, a back plate 260 of the IDC 200 can be located proximal to the cutting edge and / or trailing edge.

[0095] An integrated circuit (ICC) can be described here with reference to a wire, which may contribute to understanding the structure and / or function of the IDC 200; such descriptions do not imply that the wire 110 is a necessary component of the IDC. As described herein, an IDC 200 according to an embodiment described herein, in combination with a received wire, can form a connection arrangement 300 comprising the wire 110 and the IDC 200. The descriptions of the embodiments of the connection arrangements 300 herein are also intended to describe embodiments of the IDC 200.

[0096] In this case, the wire gauge can be a standard wire gauge, e.g. according to the international standard of the International Electrotechnical Commission (IEC) for conductors of insulated cables, e.g. IEC 60228.

[0097] In this context, "axis" can be used synonymously with "receiving axis". "Receiving axis" can be used synonymously with "insertion axis". In this context, a "cutting edge" can have a curve and / or a vertex or a sharp edge for cutting that extends along the curve.

[0098] In this context, a radial direction can be radial with respect to the imaging axis. The imaging direction and the imaging axis can be collinear.
