[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described.

[0010] The crimp terminals of this disclosure are as follows:

[0011] (1) A crimp terminal to which an insulated wire is connected, comprising: a first crimp plate having a first slit; a second crimp plate having a second slit; and a parallel support portion that supports the first crimp plate and the second crimp plate in a parallel state with a gap between them, wherein the first crimp plate has a first edge, the first slit opens at the first edge and includes a first intersecting extension portion that extends in a direction intersecting the first edge, and the second crimp plate has a second edge, the second slit opens at the second edge and includes a second intersecting extension portion that extends in a direction intersecting the second edge.

[0012] With this crimp terminal, the insulated wire is connected to the crimp terminal by inserting it into the first and second slits. Since the insulated wire is supported by the first and second slits, the support state of the insulated wire is easily stabilized. The first slit includes a first intersecting extension that extends in a direction intersecting the first end edge, and the second slit includes a second intersecting extension that extends in a direction intersecting the second end edge. When the insulated wire is held by the first and second intersecting extensions, any movement of the insulated wire toward the first and second end edges is easily hindered. Therefore, the insulated wire is less likely to detach from the crimp terminal, and the support state of the insulated wire is easily stabilized. The first intersecting extension intersects the first end edge, and the second intersecting extension intersects the second end edge. Therefore, even if the first and second slits are made longer, the first and second pressure contact plates can be made more compact, and the entire pressure contact terminal can also be made more compact.

[0013] (2) The crimp terminal of (1), wherein the first intersecting extension may extend along the second intersecting extension when viewed in a direction perpendicular to the first crimp plate.

[0014] As a result, at any position of the first cross-extending portion and the second cross-extending portion, it is easy to support the covered wire in a posture perpendicular to the first pressure contact plate.

[0015] (3) The pressure contact terminal of (1), when viewed in a direction perpendicular to the first pressure contact plate, the first cross-extending portion may extend along a direction intersecting the second cross-extending portion.

[0016] In this case, when the covered wire attempts to come out along the first cross-extending portion, the coming-out is suppressed by the second cross-extending portion. When the covered wire attempts to come out along the second cross-extending portion, the coming-out is suppressed by the first cross-extending portion. Therefore, it is difficult for the covered wire to come out.

[0017] Also, when the core wire of the covered wire is a stranded wire, the stranded wire is sandwiched from different directions by the first cross-extending portion and the second cross-extending portion. Therefore, it is difficult for the stranded wire to come apart.

[0018] (4) The pressure contact terminal of (3), when viewed in a direction perpendicular to the first pressure contact plate, the opening of the first slit and the opening of the second slit may at least partially overlap.

[0019] As a result, it is easy to insert the covered wire into the first slit and the second slit.

[0020] (5) The pressure contact terminal of (3), when viewed in a direction perpendicular to the first pressure contact plate, the inner side portion of the first slit and the inner side portion of the second slit may at least partially overlap.

[0021] In this case, in a state where the covered wire is disposed on the inner side of the slit, it is difficult to tilt with respect to the first pressure contact plate and the second pressure contact plate.

[0022] (6) The pressure contact terminal of (3), when viewed in a direction perpendicular to the first pressure contact plate, the first slit and the second slit may intersect.

[0023] In this case, the insulated wire is easier to insert into the first and second slits, and the inclination of the insulated wire relative to the first and second pressure contact plates is easier to reduce.

[0024] (7) Any one of (1) to (6) is a pressure contact terminal, wherein the first crossing extension portion may have a first bent portion that is bent when viewed in a direction perpendicular to the first pressure contact plate.

[0025] In this case, if the insulated wire tries to move in the same direction, it will stop at the bend. Therefore, it is difficult for the insulated wire to slip out of the first slit.

[0026] (8)(7) The crimp terminal, wherein the second crossing extension portion may have a second bent portion that is bent when viewed in a direction perpendicular to the second crimp plate.

[0027] This makes it difficult for the insulated wire to slip out of the second slit.

[0028] [Details of the embodiments of this disclosure] Specific examples of the crimp terminals of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited to these examples, and all modifications are intended to be included in the meaning and scope equivalent to the claims as indicated by the claims.

[0029] [Embodiment 1] The following describes the crimp terminal according to Embodiment 1. Figure 1 is a perspective view showing the crimp terminal 20. Figure 2 is a front view showing the crimp terminal 20. Figure 3 is a plan view showing the crimp terminal 20.

[0030] The crimp terminal 20 is the terminal to which the insulated wire 10 is connected.

[0031] The insulated electric wire 10 has a core wire 11 and an insulation 12.

[0032] The core wire 11 is a linear conductor made of metal or the like. The metal may be, for example, copper, copper alloy, aluminum, or aluminum alloy. The core wire 11 may be a single-core wire or a bundled wire made of multiple strands. The bundled wire may be a stranded wire made of multiple strands twisted together.

[0033] The coating 12 is an insulator that covers the core wire 11. The coating 12 is, for example, a resin extruded onto the core wire 11.

[0034] The crimp terminal 20 is a terminal that is cut into the insulation 12 and kept pressed against the core wire 11. The crimp terminal 20 comprises a first crimp plate 22, a second crimp plate 32, and a parallel support portion 40.

[0035] The crimp terminal 20 may be formed, for example, by press-forming a metal plate. The metal plate may be made of copper, copper alloy, aluminum, aluminum alloy, iron, stainless steel, or other metals. The crimp terminal 20 may be plated. For example, the crimp terminal 20 may be manufactured by punching a metal plate into a predetermined shape having slits 24, 34 and then bending it. Such a crimp terminal 20 can be formed, for example, by continuously punching it out from a single metal plate.

[0036] The first pressure welding plate 22 is formed in a plate shape. The external shape of the first pressure welding plate 22 is arbitrary. In this embodiment, the first pressure welding plate 22 is formed in a rectangular plate shape that is long in one direction. The first pressure welding plate 22 has a first edge 22e. The first edge 22e is an edge that extends in a straight line. In this embodiment, the edge along one of the short sides of the first pressure welding plate 22 is the first edge 22e.

[0037] The first pressure plate 22 has a first slit 24. The first slit 24 opens at a first edge 22e and extends inward from the first edge 22e towards the inside of the first pressure plate 22. The first slit 24 includes a first intersecting extension 25 that extends in a direction intersecting the first edge 22e.

[0038] The first intersecting extension 25 may be a part of the first slit 24 or the entirety of it. In this embodiment, the entirety of the first slit 24 is the first intersecting extension 25. More specifically, the first slit 24 is a slit that extends linearly, intersecting the first edge 22e, and the entirety of it is the first intersecting extension 25.

[0039] The angle that the first intersecting extension 25 makes with respect to the first end edge 22e is greater than 0 degrees and less than or equal to 90 degrees. The first intersecting extension 25 may be inclined obliquely with respect to the first end edge 22e, and the angle that the first intersecting extension 25 makes with respect to the first end edge 22e may be greater than 0 degrees and less than 90 degrees. The angle that the first intersecting extension 25 makes with respect to the first end edge 22e may be, for example, 15 degrees or more and 75 degrees or less, or 30 degrees or more and 60 degrees or less.

[0040] The length of the first slit 24 is greater than the diameter of the insulated wire 10, for example, it may be three times or more, or five times or more, the diameter of the insulated wire 10.

[0041] The width of the first slit 24 is smaller than the diameter of the insulated wire 10 and is the same as or smaller than the diameter of the core wire 11. Therefore, when the insulated wire 10 is inserted into the first slit 24, both side edges of the first slit 24 cut into the insulation 12 and can make contact with the core wire 11 while being pressed against it.

[0042] The side edges of the first slit 24 may be referred to as crimping blades 24e. The pair of crimping blades 24e face each other, and when the insulated wire 10 is inserted between them, the pair of crimping blades 24e can contact the core wire 11.

[0043] The insulated wire 10 may be inserted into the first slit 24 until it touches the innermost part of the first slit 24. The inner part of the first slit 24 may touch the outer circumference of the insulation 12, or it may cut into the insulation 12 and touch the core wire 11.

[0044] Since the first slit 24 intersects the first edge 22e, one corner of the opening side of the first slit 24 is acute, and the other is obtuse. The acute corner may be rounded or chamfered.

[0045] The second pressure welding plate 32 may have the same configuration as the first pressure welding plate 22. That is, the second pressure welding plate 32 may have a second edge 32e corresponding to the first edge 22e and a second slit 34 corresponding to the first slit 24. The second slit 34 may have a second intersecting extension 35 corresponding to the first intersecting extension 25.

[0046] The parallel support section 40 supports the first pressure plate 22 and the second pressure plate 32 in a parallel state with a gap between them. The parallel support section 40 is connected, for example, to the periphery of the first pressure plate 22 and the periphery of the second pressure plate 32, and supports the first pressure plate 22 and the second pressure plate 32 in a parallel state.

[0047] In this embodiment, the parallel support portion 40 is plate-shaped and extends to one side edge of the first pressure contact plate 22 and one side edge of the second pressure contact plate 32. From each of the two side edges of the parallel support portion 40, the first pressure contact plate 22 and the second pressure contact plate 32 extend in a direction perpendicular to the parallel support portion 40, thereby maintaining the first pressure contact plate 22 and the second pressure contact plate 32 in a parallel state.

[0048] In this embodiment, an additional piece 42 extends from the other side edge of the first pressure plate 22, and an additional piece 44 extends from the other side edge of the second pressure plate 32, with the additional pieces 42 and 44 overlapping.

[0049] The first pressure plate 22, the second pressure plate 32, the parallel support section 40, and the additional pieces 42 and 44 are all rectangular cylindrical in shape.

[0050] The configuration of the parallel support section is arbitrary. For example, the parallel support section may connect the first pressure contact plate 22 and the second pressure contact plate 32 on the opposite side of the first edge 22e and the second edge 32e. The parallel support section, the first pressure contact plate, and the second pressure contact plate may be formed separately, and the parallel support section may serve as a holder that supports the first and second pressure contact plates in parallel. In this case, the first and second pressure contact plates may be electrically connected by a separate conductor. The pressure contact terminal may include three or more pressure contact plates.

[0051] The relative positional relationship between the first slit 24 and the second slit 34 is arbitrary, and the positional relationship between the first intersecting extension 25 and the second intersecting extension 35 is also arbitrary.

[0052] In this embodiment, when viewed in a direction perpendicular to the first pressure plate 22, the first intersecting extension portion 25 (first slit 24) extends along the second intersecting extension portion 35 (second slit 34). When viewed in a direction perpendicular to the first pressure plate 22, the first intersecting extension portion 25 (first slit 24) and the second intersecting extension portion 35 (second slit 34) overlap.

[0053] Therefore, when viewed in a direction perpendicular to the first pressure plate 22, the insulated wire 10 can be inserted into the openings of the first slit 24 and the second slit 34 at the same position. Also, when viewed in the same direction, by moving the insulated wire 10 in the same way within the first slit 24 and the second slit 34, the insulated wire 10 can be moved toward the back of the first slit 24 and the second slit 34. Also, when viewed in the same direction, with the insulated wire 10 positioned at the same position at any arbitrary position within the first slit 24 and the second slit 34, the first pressure plate 22 and the second pressure plate 32 can be connected to the core wire 11. In this state, it is easy to position the insulated wire 10 perpendicular to the first pressure plate 22 and the second pressure plate 32. The insulated wire 10 may be supported on the back side of the first slit 24 and the second slit 34.

[0054] The pressure contact plate 22 may have a mating connection portion 48. The mating connection portion 48 is the part that is connected to the mating member to which the insulated wire 10 is connected. The mating connection portion 48 may be, for example, a plate-shaped or pin-shaped male terminal. The mating connection portion may be, for example, a cylindrical female terminal. The mating connection portion may be a part that is pressure-connected to the insulated wire 10, similar to the first pressure contact plate 22 and the second pressure contact plate 32. The mating connection portion may be a part that is screw-connected, soldered, or welded to the mating connection portion.

[0055] The mating connection portion may be connected to the first pressure contact plate 22. Such a pressure contact terminal 20 may be formed, for example, by press-forming a metal plate.

[0056] With the crimp terminal 20 configured in this way, the insulated wire 10 is connected to the crimp terminal 20 by inserting it into the first slit 24 and the second slit 34. Since the insulated wire 10 is supported by the first slit 24 and the second slit 34, the insulated wire 10 is supported at least at two points separated in its longitudinal direction, making it easier to stabilize the support state of the insulated wire 10.

[0057] Furthermore, the first slit 24 includes a first intersecting extension 25 that extends in a direction intersecting the first end edge 22e, and the second slit 34 includes a second intersecting extension 35 that extends in a direction intersecting the second end edge 32e. When the insulated wire 10 is held by the first intersecting extension 25 and the second intersecting extension 35, any attempt to move the insulated wire 10 toward the first end edge 22e and the second end edge 32e is easily hindered.

[0058] For example, if the insulated wire 10 and the crimp terminal 20 are lifted by holding both ends of the insulated wire 10, the insulated wire 10 may try to move along the extending direction of the crimp terminal 20. In this case, the insulated wire 10 is pressed diagonally against the end edges 22e and 32e of the first and second intersecting extensions 25 and 35. Therefore, compared to the case where the slit is perpendicular to the end edge, the insulated wire 10 is less likely to move towards the end edges 22e and 32e. Thus, the insulated wire 10 is less likely to detach from the crimp terminal 20, and from this point of view, the support state of the insulated wire 10 is more stable. Furthermore, even without sealing the opening of the slit with a welded member, the insulated wire 10 can be prevented from coming loose with a simple configuration.

[0059] Furthermore, the first intersecting extension portion 25 intersects with the first edge 22e, and the second intersecting extension portion 35 intersects with the second edge 32e. Therefore, even if the first slit 24 and the second slit 34 are made longer, the first and second pressure plates 22 and 32 can be made more compact.

[0060] In particular, if the first intersecting extension portion 25 extends diagonally with respect to the first edge 22e, and the second intersecting extension portion 35 extends diagonally with respect to the second edge 32e, it becomes easier to shorten the lengths of the contact plates 22 and 32.

[0061] Therefore, even if the first slit 24 and the second slit 34 are made longer, the first and second pressure contact plates 22 and 32 can be made more compact. By making the first and second slits 24 and 34 longer, the insulated wires 10 become less likely to detach from the slits 24 and 34.

[0062] Furthermore, when viewed in a direction perpendicular to the first pressure contact plate 22, the first intersecting extension portion 25 extends along the second intersecting extension portion 35. Therefore, the insulated wire 10 can be easily supported at any position on the first intersecting extension portion 25 and the second intersecting extension portion 35 in a position perpendicular to the first pressure contact plate 22. In this case, regardless of the final support position of the insulated wire 10, the insulated wire 10 can be supported in a position perpendicular to the first pressure contact plate 22. This makes the connection work of the insulated wire 10 easier.

[0063] Figure 4 shows a connector 51 in which a crimp terminal 20 is housed within a housing 50. The housing 50 is made of resin or the like. The housing 50 has a holder 52 that supports the crimp terminal 20. The holder 52 supports the crimp terminal 20 in a position where the outer portions of the end edges 22e, 32e and the slits 24, 34 are exposed.

[0064] The mating connection portion 48 of the crimp terminal 20 is exposed from the holder 52 so that it can be connected to the mating member.

[0065] An outlet 54h for leading the insulated wire 10 to the outside is formed in the outer wall 54 of the housing 50. The housing 50 may also have a wire holder 56 outside the holder 52 that supports the insulated wire 10 extending from the crimp terminal 20. The wire holder 56 is, for example, a projection that protrudes from the bottom of the housing 50, and a recess 56h is formed in the projection that allows the insulated wire 10 to be fitted into it.

[0066] The insulated wire 10 passes through the outlet 54h and, while fitted into the recess 56h, is crimp-connected to the crimp terminal 20 inside the holder 52.

[0067] The housing 50 may hold multiple pressure contact plates 22 and insulated wires 10.

[0068] The connector 51 described above can be used, for example, to connect an insulated wire 10 to another connector, or to connect two insulated wires 10 to each other.

[0069] [Embodiment 2] The crimp terminal 120 according to Embodiment 2 will now be described. Figure 5 is a perspective view showing the crimp terminal 120, and Figure 6 is a front view showing the same crimp terminal 120. In this description, the same reference numerals are used for components similar to those described in Embodiment 1, and their descriptions are omitted. The description will focus on the differences from Embodiment 1.

[0070] The crimp terminal 120 has a first slit 124 corresponding to the first slit 24 and a second slit 134 corresponding to the second slit 34. The first slit 124 has a first cross extension portion 125 corresponding to the first cross extension portion 25. The second slit 134 has a second cross extension portion 135 corresponding to the second cross extension portion 35.

[0071] In this embodiment, the entirety of the first slit 124 constitutes the first intersecting extension portion 125. The entirety of the second slit 134 constitutes the second intersecting extension portion 135.

[0072] Viewed in a direction perpendicular to the first pressure plate 22, the first intersecting extension portion 125 extends along a direction intersecting the second intersecting extension portion 135.

[0073] Furthermore, when viewed in a direction perpendicular to the first pressure plate 22, the opening 124a of the first slit 124 and the opening 134a of the second slit overlap at least partially. In this case, for example, when viewed in a direction perpendicular to the first pressure plate 22, the width direction of the opening 124a of the first slit 124 and the width direction of the opening 134a of the second slit 134 may overlap by 1 / 3 or more, or 1 / 4 or more, or 1 / 5 or more. The range of the opening 124a of the first slit 124 and the range of the opening 134a of the second slit 134 may coincide in the extending direction of the edge 22e.

[0074] The first slit 124 and the second slit 134 are inclined in opposite directions from the positions of the overlapping openings 124a and 134a, and extend toward the inside of the first pressure plate 22 or the second pressure plate 32.

[0075] Therefore, the inner portion 124b of the first slit 124 and the inner portion 134b of the second slit 134 are offset along the extending direction of the edge 22e.

[0076] With this crimp terminal 120, the same effects as the crimp terminal 20 can be obtained, except for the effects caused by the slits extending in the same direction.

[0077] In addition, with this crimp terminal 120, the first intersecting extension portion 125 extends in a direction intersecting the second intersecting extension portion 135. Therefore, when the insulated wire 10 tries to pull out along the first intersecting extension portion 125, the insulated wire 10 is strongly pressed against one side edge of the second intersecting extension portion 135. As a result, the pulling out of the insulated wire 10 is suppressed by the second intersecting extension portion 135. When the insulated wire 10 tries to pull out along the second intersecting extension portion 135, this pulling out is suppressed by the first intersecting extension portion 125. Therefore, it is difficult for the insulated wire 10 to pull out from both the first intersecting extension portion 125 and the second intersecting extension portion 135 simultaneously.

[0078] Furthermore, if the core wire 11 of the insulated electric wire 10 is a bundled wire, the core wire 11 is sandwiched along the width direction of the first crossing extension 125 by the first crossing extension 125, and sandwiched along the width direction of the second crossing extension 135 by the second crossing extension 135. Therefore, the core wire 11 is sandwiched from different directions by the first crossing extension 125 and the second crossing extension 135. As a result, the bundled wire 11 is less likely to fall apart.

[0079] Furthermore, when viewed in a direction perpendicular to the first pressure contact plate 22, the opening 124a of the first slit 124 and the opening 134a of the second slit 134 overlap at least partially. Therefore, by straightening the insulated wire 10 while aligning it perpendicular to the first pressure contact plate 22 and the second pressure contact plate 32, the insulated wire 10 can be easily inserted into the first slit 124 and the second slit 134.

[0080] When viewed in a direction perpendicular to the first pressure plate 22, the first intersecting extension portion 125 extends along a direction intersecting the second intersecting extension portion 135, and the positional relationship between the first slit 124 and the second slit 134 is not limited to the above example.

[0081] As shown in Figure 7, for the first modified example, terminal 120A may overlap at least partially with the rear portion 124Ab of the first slit 124A, which corresponds to the first slit 124, and the rear portion 134Ab of the second slit 134A, which corresponds to the second slit 134, when viewed in a direction perpendicular to the first pressure contact plate 22.

[0082] More specifically, the inner portion 124Ab of the first slit 124A may be the inner portion that is narrower than the parallel side edges of the first slit 124A. The inner portion 124Ab may also be a portion that forms a partial arc shape at the inner side of the first slit 124A. The inner portion 134Ab of the second slit 134A may be understood in the same way as above.

[0083] When viewed along a direction perpendicular to the first pressure plate 22, the rear portion 124Ab and the rear portion 134Ab may completely overlap. They may overlap such that the widthwise center of the rear portion 124Ab is located within or on the rear portion 124Ab, and the widthwise center of the rear portion 124Ab is located within or on the rear portion 134Ab.

[0084] In this modified example, the first slit 124A and the second slit 134A extend toward the edges 22e and 32e, inclined toward opposite directions from the inner portions 124Ab and 134Ab, which overlap in at least part. Therefore, the openings 124Aa of the first slit 124A and 134Aa of the second slit 134A are positioned at different locations in the extending direction of the edges 22e and 32e. The openings 124Aa of the first slit 124A and 134Aa of the second slit 134A are positioned at different locations, offset by half a meter from each other, in the extending direction of the edges 22e and 32e.

[0085] According to this modification, with the insulated wire 10 positioned at the back of the slits 124A and 134A, the support points for the insulated wire 10 by the first pressure plate 22 and the support points for the insulated wire 10 by the second pressure plate 32 are likely to be positioned at the same or close positions when viewed in a direction perpendicular to the first pressure plate 22. Therefore, the insulated wire 10 is less likely to tilt significantly with respect to the first and second pressure plates 22 and 32. In this case, the side edges of the slits 124A and 134A are less likely to come into localized contact with the core wire 11.

[0086] As shown in Figure 8, in the second modified example, terminal 120B may intersect with the first slit 124B corresponding to the first slit 124 and the second slit 134B corresponding to the second slit 134 when viewed in a direction perpendicular to the first pressure contact plate 22. The intersection may occur at the longitudinal middle portion of the first slit 124B and the longitudinal middle portion of the second slit 134B.

[0087] In this modified example, when viewed along the direction perpendicular to the first pressure plate 22, the rear portion 124Bb and the rear portion 124Bb are offset in the extending direction of the edge 22e. When viewed along the same direction, the opening 124Ba and the opening 134Ba are offset to the opposite side from the rear portions 124Bb and 124Bb in the extending direction of the edge 22e. The first slit 124B and the second slit 134B are inclined in opposite directions from each other, and the longitudinal middle portion of the first slit 124B and the longitudinal middle portion of the second slit 134B intersect.

[0088] In this modified version, the displacement between opening 124Ba and opening 134Ba can be reduced compared to the second modified version. Also, the displacement of the rear portions 124Bb and 134Bb can be reduced compared to the first modified version. Therefore, it is easier to insert the insulated wire 10 into opening 124Ba and opening 134Ba, and the inclination of the insulated wire 10 with respect to the pressure contact plates 22 and 32 can be reduced when the insulated wire 10 is positioned in the rear portions 124Bb and 134Bb.

[0089] [Embodiment 3] The crimp terminal 220 according to Embodiment 3 will now be described. Figure 9 is a perspective view showing the crimp terminal 220, and Figure 10 is a front view showing the same crimp terminal 220. In describing this embodiment, components similar to those described in Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted, and the differences from Embodiment 1 will be the focus of the description.

[0090] The crimp terminal 220 has a first slit 224 corresponding to the first slit 24 and a second slit 234 corresponding to the second slit 34. The first slit 224 has a first cross extension portion 225 corresponding to the first cross extension portion 25. The second slit 234 has a second cross extension portion 235 corresponding to the second cross extension portion 35.

[0091] In this embodiment, the entirety of the first slit 224 constitutes the first intersecting extension portion 225. The entirety of the second slit 234 constitutes the second intersecting extension portion 235.

[0092] The shapes of the first intersecting extension portion 225 and the second intersecting extension portion 235 are different from those of the first intersecting extension portion 25 and the second intersecting extension portion 35.

[0093] In other words, the first intersecting extension 225 has a first bent portion 225c that is curved when viewed in a direction perpendicular to the first pressure plate 22. More specifically, the first intersecting extension 225 includes a first entrance-side portion 225a that extends from the first end edge 22e into the first pressure plate 22, a first bent portion 225c located on the rear side of the entrance-side portion 225a, and a first rear-side portion 225b that extends further from the first bent portion 225c.

[0094] In other words, the first intersecting extension 225 consists of a first entrance-side portion 225a, a first bent portion 225c, and a first rear-side portion 225b, which are continuous in this order from the entrance towards the rear.

[0095] The first entrance side portion 225a is inclined with respect to the first edge 22e and extends away from the first edge 22e.

[0096] The first rear portion 225b is also inclined with respect to the first edge 22e. The first rear portion 225b is further back than the first entrance portion 225a, and is inclined in the opposite direction to the first entrance portion 225a, moving away from the first edge 22e.

[0097] The first bent portion 225c forms the bent shape of the first slit 224 between the first entrance side portion 225a and the first inner side portion 225b. The bending angle of the first bent portion 225c is arbitrary and may be obtuse, right, or acute.

[0098] The second intersecting extension 235 also has a second bent portion 235c that is curved when viewed in a direction perpendicular to the second pressure contact plate 32.

[0099] In this embodiment, the second intersecting extension portion 235 has the same shape as the first intersecting extension portion 225. That is, the second intersecting extension portion 235, like the first intersecting extension portion 225, includes a second entrance-side portion 235a corresponding to the first entrance-side portion 225a, a second bent portion 235c corresponding to the first bent portion 225c, and a second rear-side portion 235b corresponding to the first rear-side portion 225b.

[0100] Viewed along a direction perpendicular to the first pressure plate 22, the second intersecting extension 235 extends along the first intersecting extension 225.

[0101] The insulated wire 10 is preferably held in place by the inner portions 225b and 235b, beyond the bent portions 225c and 235c.

[0102] When viewed along a direction perpendicular to the first pressure plate 22, the first intersecting extension portion 225 and the second intersecting extension portion 235 do not have to be positioned in the same location or oriented in the same direction. For example, the first intersecting extension portion 225 and the second intersecting extension portion 235 may be offset in the extending direction of the edges 22e and 32e. The first intersecting extension portion 225 and the second intersecting extension portion 235 may be formed to be convex in opposite directions in the extending direction of the edges 22e and 32e. The intersecting extension portion may have multiple bent portions.

[0103] The first intersecting extension 225 and the second intersecting extension 235 do not have to be the same shape. For example, the first intersecting extension and the second intersecting extension may be bent at different angles. Also, the distance of the bent portion relative to the edge may be different for the first intersecting extension and the second intersecting extension. Furthermore, the first intersecting extension and the second intersecting extension may each extend at different angles relative to the edge.

[0104] With this crimp terminal 220, the same effects as the crimp terminal 20 can be obtained, except for the effect caused by the slit extending straight.

[0105] In addition, since the first intersecting extension portion 225 has a first bent portion 225c that is curved when viewed in a direction perpendicular to the first pressure contact plate 22, the insulated wire 10 will stop at the first bent portion 225c when it tries to move in the same direction. Therefore, the insulated wire 10 is less likely to come out of the first slit 224.

[0106] Furthermore, since the second intersecting extension portion 235 also has a second bent portion 235c that is curved when viewed in a direction perpendicular to the second pressure contact plate 32, the insulated wire 10 is less likely to slip out of the second slit 234.

[0107] Since the second intersecting extension 235 extends along the first intersecting extension 225, the insulated wire 10 can be held in the back of the slits 224 and 234 by moving the insulated wire 10 along the same path on both the first and second pressure contact plates 22 and 32. This makes the connection work of the insulated wire 10 easier.

[0108] [Differentiation] In each of the above embodiments, the portion of the slit that extends in a direction intersecting the edge may be located in the middle of the slit's extension direction. For example, the slit may have a configuration that combines a portion that extends in a direction intersecting the edge and a portion that extends in a direction perpendicular to the edge.

[0109] The insulated wire 10 may be located at the back of the slit, or it may be located in the middle of the slit in the direction of extension.

[0110] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other.

[0111] For example, a straight slit like in Embodiment 1 and a slit that bends midway like in Embodiment 3 may be combined. [Explanation of Symbols]
