Below, an embodiment of the connector and the electric wire with connector according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment.

[Embodiment]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a connector and an electric wire with a connector according to the present invention will be described with reference to FIGS.

The reference numeral 1 in Figs. 1 to 8 indicates the electric wire with connector of this embodiment. This electric wire with connector 1 includes a plurality of electric wires 10 and a connector 20 attached to the plurality of electric wires 10.

The electric wire with connector 1 includes at least a twisted pair 10A formed by twisting two electric wires 10 together (FIGS. 1, 2, and 5 to 8). In the electric wire with connector 1, the twisted pair 10A is folded back from a folding point 10A3 to a first twisted wire section side _10A1 and a second twisted wire section side _10A2 , and a connector 20 is attached to the folding point _10A3 (FIG. 2). For example, the electric wire with connector 1 is formed by attaching the connector 20 to the folding point _10A3 of one twisted pair 10A drawn _out from a trunk 10X (FIG. 9), and constitutes a wire harness WH together with the trunk 10X. The connector 20 is fitted and connected to, for example, a mating connector (not shown) of an electronic device EP (FIG. 9).

Although not shown in the figure, the electric wire 10 has a core wire that serves as a conductor and a coating that covers the core wire.

The connector 20 includes terminal fittings 30 and a housing 40 (FIGS. 2 to 6 and 8). In this connector 20, the terminal fittings 30 for each electric wire 10 are housed in the housing 40. Here, a terminal fitting 30 is provided for each electric wire 10 of the twisted pair wire 10A.

The terminal fitting 30 is made of a conductive material such as metal. The terminal fitting 30 is formed into a predetermined shape, for example, by press forming such as bending or cutting a metal plate as a base material.

The terminal fitting 30 has a pair of pressure-welding bodies 31, 31 that press against the core wire of the pressure-welded part 10a of the electric wire 10 as an electric wire connecting part that physically and electrically connects to the core wire of the electric wire 10 (Figs. 2 to 6 and 8). The pair of pressure-welding bodies 31, 31 are arranged opposite each other with a gap between their ends, and when the electric wire 10 is inserted between the ends, the ends cut the insulation and press against the core wire. The electric wire 10 that is pressure-welded to the pair of pressure-welding bodies 31, 31 is pulled out from between the pair of pressure-welding bodies in a direction perpendicular to the direction in which the pressure-welding bodies 31, 31 are arranged opposite each other and the direction in which the electric wire 10 is inserted between the pressure-welding bodies 31, 31. The pressure-welding body 31 is formed as a single body. The end of the pressure-welding body 31 may be formed as a blade-shaped pressure-welding blade, or may be formed as a flat surface having a thickness equivalent to the plate thickness of the base material.

This terminal fitting 30 is configured as a connection terminal that is physically and electrically connected to a mating terminal fitting, and has a pair of pressure contacts 31, 31 and one terminal connection portion 32 (Figs. 2, 4, 6, and 8). The terminal connection portion 32 and the mating terminal connection portion of the mating terminal fitting are physically and electrically connected to each other by a mutual fitting connection, one of which is formed in a female terminal shape and the other of which is formed in a male terminal shape. The terminal connection portion 32 shown here is formed in a female terminal shape.

In the terminal fitting 30 shown here, a pair of pressure-contact bodies 31, 31 and a terminal connection portion 32 are arranged in the direction of fitting and connecting to the mating terminal connection portion. In this terminal fitting 30, the pair of pressure-contact bodies 31, 31 and the terminal connection portion 32 are connected via a flat connecting portion 33 (Figures 2, 4, 6, and 8). In the terminal fitting 30 shown here, the pair of pressure-contact bodies 31, 31 and the terminal connection portion 32 protrude in opposite directions when viewed from the connecting portion 33. Here, the pair of pressure-contact bodies 31, 31 protrude from one flat surface of the connecting portion 33, and the terminal connection portion 32 protrudes from the other flat surface of the connecting portion 33.

In the electric wire with connector 1 shown here, the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 of the twisted pair wire 10A are pulled out of the housing 40 in a direction opposite to the mating connection direction of the terminal connection portion 32. For this reason, the terminal fitting 30 is formed with a pair of insulation displacement bodies 31, 31 so as to pull out the first twisted wire portion side 10A1 and the second twisted wire portion side _10A2 in the pulling direction. For example, in this electric wire with connector ₁ , the pulling direction of the twisted pair wire 10A pulled out from the trunk line 10X is the mating connection direction of the connector 20 (FIG. 9).

The housing 40 is molded from an insulating material such as synthetic resin.

In this housing 40, the terminal fittings 30 for each electric wire 10 are housed, and the twisted pair wire _10A is housed folded back from a folding point _10A3 into a first twisted wire portion side _10A1 and a second twisted wire portion side 10A2.

The housing 40 has a first housing body 40A and a second housing body 40B that is assembled to the first housing body 40A (FIGS. 1 to 8). In the housing 40, when the first housing body 40A and the second housing body 40B are in the assembled position, the twisted pair wire 10A is folded back in a U-shape starting from a folding point _10A3 . In the housing 40, when the first housing body 40A and the second housing body 40B are in the assembled position, the first twisted wire portion side _10A1 of the twisted pair wire 10A is arranged in the first housing body 40A, and the second twisted wire portion side _10A2 of the twisted pair wire 10A is arranged in the second housing body 40B.

In this housing 40, a portion of the twisted wire pair 10A before being folded back is routed between the first housing body 40A and the second housing body 40B before being assembled, and the twisted wire pair 10A is folded back in conjunction with the assembly operation of the first housing body 40A and the second housing body 40B. Here, the first housing body 40A and the second housing body 40B are assembled while being rotated relative to each other, so that the twisted wire pair 10A is pushed and folded back by the first housing body 40A and the second housing body 40B. The housing 40 rotates the second housing body 40B together with the wiring twisted portion relative to the first housing body 40A between an open position of the first housing body 40A and the second housing body 40B where a portion of the twisted wire _10A that becomes a part of the second twisted wire portion side 10A2 after folding back (hereinafter referred to as the "routed twisted wire portion") is routed to the second housing body 40B and a closed position of the first housing body 40A and the second housing body 40B as an assembly completion position. In other words, the housing 40 rotates the second housing body 40B relative to the first housing body 40A between the open position of the first housing body 40A and the second housing body 40B where the twisted wire 10A is not folded back and the closed position of the first housing body 40A and the second housing body 40B where the twisted wire 10A is folded back. Therefore, the housing 40 has a main body hinge portion (hereinafter referred to as "first hinge portion") 40C between the first housing main body 40A and the second housing main body 40B, which is responsible for the relative rotation between them (FIGS. 1 to 8). The first hinge portion 40C is provided at a position where the second housing main body 40B can rotate relative to the first housing main body 40A between the closed position and the open position while a part of the twisted pair wire 10A is arranged between the first housing main body 40A and the second housing main body 40B. In the housing 40 shown here, a living hinge is applied to the first hinge portion 40C, and the first housing main body 40A, the second housing main body 40B, and the first hinge portion 40C are integrally molded.

The first housing body 40A has terminal accommodating chambers 41 for the terminal fittings 30 in which the terminal fittings 30 for each electric wire 10 of the twisted pair wire 10A are arranged side by side (FIGS. 2 to 8). The first twisted wire portion 10A1 of the twisted pair wire 10A having a pair of insulation displacement bodies 31, 31 pressure-welded to the electric wire ₁₀ is arranged in the first housing body 40A.

The terminal accommodating chamber 41 is broadly divided into a first accommodating portion 41a that accommodates the pair of pressure contact bodies 31, 31, and a second accommodating portion 41b that accommodates the terminal connection portion 32 (Figures 2, 4, 6, and 8).

The first housing portion 41a may be a room formed for each terminal metal fitting 30, or may be a room in which a pair of pressure-contact bodies 31, 31 of a plurality of terminal metal fittings 30 are accommodated together. When the first housing body 40A and the second housing body 40B are in the assembly completion position (closed position), the first twisted wire portion side _10A1 of the twisted pair wire 10A is accommodated in the first housing portion 41a. In the first housing portion 41a, the pair of pressure-contact bodies 31 _{, 31} of the terminal metal fitting 30 are pressure-contacted to the electric wire 10 on the first twisted wire portion side 10A1. For example, in a state in which two terminal metal fittings 30 have already been accommodated in the first housing portion 41a, a portion that will become the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back (hereinafter referred to as the "routing twisted wire portion") is inserted from an opening (hereinafter referred to as the "first opening") 41c (FIGS. 2 to 6 and 8). In the first housing 41a, the press-connected portion 10a of _each electric wire 10 on the first twisted wire portion side 10A1 is inserted into a pair of press-connecting bodies 31, 31 of the respective terminal fittings 30, and the pair of press-connecting bodies 31, 31 is press-connected to the press-connected portion 10a. The first twisted wire portion side _10A1 of the twisted pair wire 10A is drawn out of the first housing 41a through an opening (hereinafter referred to as a "second opening") 41d perpendicular to the first opening 41c (FIGS. 2 to 4, 6 and 8). The second opening 41d is used as an electric wire outlet for drawing out the first twisted wire portion side _10A1 from the housing 40. The second opening 41d is formed to open in the opposite direction to the mating connection direction of the terminal connection portion 32 to the mating terminal connection portion.

On the other hand, the second housing portion 41b is formed for each terminal fitting 30. Although not shown, the second housing portion 41b is provided with a terminal locking portion that bends when pushed by the terminal connection portion 32 during insertion, and when the accommodation of the terminal connection portion 32 is complete, the bending is released to lock the terminal connection portion 32. This terminal locking portion is intended to prevent the terminal fitting 30 from falling out of the housing 40. Here, for example, a so-called lance is provided as the terminal locking portion.

As described above, the terminal fitting 30 shown here has a pair of insulation displacement bodies 31, 31 protruding from one flat surface of the connecting portion 33, and a terminal connection portion 32 protruding from the other flat surface of the connecting portion 33. Thus, the first housing body 40A shown here has a divided structure divided into a first housing body _40A1 on the second housing portion 41b side and a second housing body _40A2 on the first housing portion 41a side (FIGS. 2 and 4). The first housing body 40A has the first housing body _40A1 and the second housing body _40A2 rotatably connected via a hinge portion _40A3 . In this first housing main body 40A, when accommodating the terminal connection portion 32 in the second accommodating portion 41b, the first accommodating body _40A1 and the second accommodating body _40A2 are opened, and after accommodating the terminal connection portion 32 in the second accommodating portion 41b, the first accommodating body _40A1 and the second accommodating body _40A2 are closed to the position shown in Figures 2 and 4 to accommodate the pair of pressure contact bodies 31, 31 in the first accommodating portion 41a. In the first housing main body 40A shown here, a living hinge is applied to the hinge portion _40A3 , and the first accommodating body _40A1 , the second accommodating body _40A2 and the hinge portion _40A3 are molded integrally.

The second housing body 40B has an electric wire routing chamber 42 in which the second twisted wire portion _10A2 of the twisted pair wire 10A is routed (FIGS. 2 to 8). In this electric wire routing chamber 42, the routed twisted wire portion that becomes the second twisted wire portion _10A2 of the twisted pair wire 10A after folding back is inserted through an opening (hereinafter referred to as a "first opening") 42a. The second twisted wire portion _10A2 of the twisted pair wire 10A is drawn out of the electric wire routing chamber 42 through an opening (hereinafter referred to as a "second opening") 42b that is perpendicular to the first opening 42a (FIGS. 2 to 8). The second opening 42b is used as an electric wire outlet for drawing out the second twisted wire portion _10A2 to the outside of the housing 40. This second opening 42b is formed so as to open in the opposite direction to the mating connection direction of the terminal connection portion 32 to the mating terminal connection portion when the first housing body 40A and the second housing body 40B are in the completed assembly position (closed position).

In this housing 40, when the first housing body 40A and the second housing body 40B are in the completed assembly position (closed position), the first accommodating portion 41a of the terminal accommodating chamber 41 and the wire routing chamber 42 are arranged opposite to each other via their respective first openings 41c, 42a, and the respective second openings 41d, 42b open in the opposite direction to the mating connection direction of the terminal connection portion 32 (Figure 2). Therefore, in this housing 40, when the first housing body 40A and the second housing body 40B are in the completed assembly position (closed position), the first twisted wire portion side _10A1 of the twisted pair wire 10A in the first accommodating portion 41a and the second twisted wire portion side _10A2 of the twisted pair wire 10A in the wire routing chamber 42 are accommodated in an opposing arrangement, and the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 are pulled out to the outside from the second openings 41d, 42b in the direction opposite to the mating connection direction of the terminal connection portion 32.

The housing 40 has a pressure member 40D1 that is interposed between the first twisted wire portion _10A1 and the second twisted wire portion _10A2 of the twisted wire pair 10A in a folded shape in the assembled position (closed position) and applies pressure to the folding point _10A3 of the twisted wire pair 10A to maintain the folded shape of the twisted wire pair _10A (FIGS. 2 to 8). The pressure member _40D1 is assembled to either the first housing body 40A or the second housing body 40B. Here, the pressure member _40D1 is assembled to the first housing body 40A. The housing 40 shown here rotates the pressure member _40D1 relative to the first housing body 40A between a closed position where the pressure member _40D1 is disposed in the first opening 41c of the first storage portion 41a and an open position where the pressure member _40D1 opens the first opening 41c. Therefore, the housing 40 has a hinge portion (hereinafter referred to as a "second hinge portion") 40E between the first housing body 40A and the pressure portion _40D1 , which is responsible for the relative rotation between them (FIGS. 3 and 5). In the housing 40 shown here, a living hinge is applied to the second hinge portion 40E, and the first housing body 40A, the second housing body 40B, the pressure portion _40D1 , the first hinge portion 40C, and the second hinge portion 40E are integrally molded.

In this connector 20 and electric wire with connector 1, when first housing body 40A and second housing body 40B are in the open position and first housing body 40A and pressure portion _40D1 are in the open position, the wiring twisted wire portion that becomes first twisted wire portion side _10A1 of twisted pair wire 10A after folding back is accommodated in first accommodating portion 41a of terminal accommodating chamber 41, and the wiring twisted wire portion that becomes second twisted wire portion side _10A2 of twisted pair wire 10A after folding back is accommodated in electric wire routing chamber 42, and a portion of twisted pair wire 10A is routed between first housing body 40A and second housing body 40B (FIGS. 3 to 6). At this time, in the first accommodating portion 41a, the pair of insulation displacement bodies 31, ₃₁ of the terminal fitting 30 are pressure-welded to the arranged twisted wire portion that becomes the first twisted wire portion side 10A1 of the twisted pair wire 10A after folding back (FIGS. 5 and 6). Thereafter, in the connector 20 and the electric wire with connector 1, the pressing portion _40D1 is rotated to the closed position relative to the first housing body 40A around the second hinge portion 40E (FIGS. 7 and 8). Then, in the connector 20 and the electric wire with connector 1, the second housing body 40B is rotated to the closed position relative to the first housing body 40A together with the twisted pair wire 10A around the first hinge portion 40C (FIGS. 1 and 2). As a result, in the connector 20 and the electric wire with connector ₁ , the twisted pair wire 10A is folded back starting from the folding back point _10A3 pressed by the pressing portion 40D1. Here, the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 of the folded twisted wire pair 10A are pulled out in the opposite direction to the mating connection direction of the terminal connection portion 32 to the mating terminal connection portion. For this reason, in the housing 40, when the first housing body 40A and the second housing body 40B are in the open position and the first housing body 40A and the pressure portion _40D1 are in the open position, the first hinge portion 40C is provided at a position where the axial direction of the rotation shaft is perpendicular to the wiring direction of the twisted wire pair 10A.

As described above, in the connector 20 and the electric wire with connector 1 of this embodiment, the twisted pair wire 10A is accommodated in the housing 40 while the folded shape is maintained by the pressing portion _40D1 . For example, in this connector 20 and the electric wire with connector 1, it is preferable that the pressing portion _40D1 applies pressure to the folded point _10A3 and the pressing portion _{40D1 presses the folded point 10A3 against the inner wall surface of the housing 40. Here, the pressing portion 40D1 presses the} folded point _10A3 against the inner wall surface 40Ba arranged opposite to the first opening 42a of the second housing main body 40B with a gap therebetween (FIG. 2). As a result, in this connector 20 and the electric wire with connector 1, the twisted pair wire 10A is accommodated in the housing 40 while maintaining the folded shape. Therefore, in the connector 20 and the electric wire with connector 1, the twist of the two electric wires 10 of the twisted pair 10A is unlikely to be untwisted, and deterioration of communication performance can be suppressed.

Incidentally, the housing 40 of this embodiment further has an elastic deformation portion _40D2 that applies pressure from the pressure portion _40D1 to the turn-back point _10A3 of the twisted pair wire 10A with a resilient force accompanying elastic deformation (FIGS. 2 to 8). As a result, in the connector 20 and the connector-attached electric wire 1 of this embodiment, when the pressure portion _40D1 applies pressure to the turn-back point _10A3 , the reaction force received by the pressure portion _40D1 from the turn-back point _10A3 can be absorbed by the elastic deformation portion _40D2 . Therefore, in this connector 20 and the connector-attached electric wire 1, since excessive pressure is unlikely to be applied from the pressure portion _40D1 to the turn-back point _10A3 , it is possible to suppress untwisting of the twisted pair wire 10A while ensuring the durability of the twisted pair wire 10A, the pressure portion _40D1 , and the second hinge portion 40E, and to suppress deterioration of communication performance.

Specifically, the pressure applying portion _40D1 and the elastic deformation portion _40D2 in this embodiment are provided on a cover member 40D that closes the first opening 41c of the first storage portion 41a (FIGS. 2 to 8).

In this cover member 40D, a plate-shaped elastic deformation portion _40D2 is connected to the second hinge portion 40E. The second hinge portion 40E shown here is provided between the second housing main body 40B and the elastic deformation portion _40D2 at a position where the axial direction of its rotation shaft is perpendicular to the axial direction of the rotation shaft of the first hinge portion 40C.

In addition, the cover member 40D is provided with a cylindrical pressure member _40D1 at the end on the first hinge portion 40C side when the cover member 40D covers the first opening 41c. The pressure member _40D1 is provided so that the axis of the cylinder faces the same direction as the rotation axis of the first hinge portion 40C when the cover member 40D covers the first opening 41c. That is, the pressure member _40D1 shown here is provided with an arc-shaped surface that aligns the electric wire 10 at the turn-back point _10A3 in the circumferential direction. The arc-shaped surface is formed to have a curvature that does not cause excessive bending stress to the electric wire 10 at the turn-back point _10A3 . The excessive bending stress is, for example, a bending stress that reduces the durability of the twisted pair wire 10A or a bending stress that may cause untwisting of the twisted pair wire 10A. Therefore, in this respect, the connector 20 and the electric wire 1 with connector can suppress deterioration in durability and communication performance.

Furthermore, in the cover member 40D, the end 40D21 of the elastic deformation portion _40D2 opposite to the pressure portion _40D1 presses the second twisted wire portion _10A2 after folding back against the inner wall surface 40Ba of the second housing body 40B (FIGS. 2, 3, 5, 7 and 8). As a result, in the connector ₂₀ and the electric wire with connector 1, the twisted pair wire 10A can be more reliably maintained in the folded shape in the housing 40, making it even more difficult for the twist of the two electric wires 10 of the twisted pair wire 10A to be untwisted, thereby enhancing the effect of suppressing the deterioration of communication performance.

[Modification 1]
10 to 15, reference numeral 2 denotes a connector-attached electric wire of this modified example. This connector-attached electric wire 2 is obtained by replacing the connector 20 in the connector-attached electric wire 1 of the above-described embodiment with a connector 120 described below.

The connector 120 of this modified example has a terminal fitting 130 and a housing 140, similar to the connector 20 of the embodiment (Figures 11 to 15).

The terminal fitting 130 of this modification has a pair of pressure contact bodies 131, 131 and a terminal connection portion 132 similar to the terminal fitting 30 of the embodiment (FIGS. 11 to 15). However, in the electric wire with connector 2 of this modification, the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 of the twisted pair wire 10A are drawn out from the housing 140 in a direction perpendicular to the mating connection direction of the terminal connection portion 132. Therefore, in the terminal fitting 130 of this modification, a pair of pressure contact bodies 131, 131 are formed so as to draw out the first twisted wire portion side _10A1 and the second twisted wire portion side 10A2 in the drawing direction. For example, in this electric wire with connector ₂ , the drawing direction of the twisted pair wire 10A drawn out from the trunk line 10X is perpendicular to the mating connection direction of the connector 20 (FIG. 16).

Furthermore, the terminal fitting 130 of this modified example also has a flat connecting portion 133 that connects the pair of pressure-contact bodies 131, 131 and the terminal connection portion 132, just like the terminal fitting 30 of the embodiment, but unlike the terminal fitting 30, the pair of pressure-contact bodies 131, 131 and the terminal connection portion 132 each protrude in the same direction when viewed from the connecting portion 133 (Figures 11, 13, and 15). Here, the pair of pressure-contact bodies 131, 131 and the terminal connection portion 132 protrude in the same direction from one flat surface of the connecting portion 133.

The housing 140 of this modification has a first housing body 140A and a second housing body 140B that are assembled together, similar to the housing 40 of the embodiment (FIGS. 10 to 15). In the housing 140 of this modification, the twisted pair wire 10A is folded back in a U-shape starting from a folding point _10A3 when the first housing body 140A and the second housing body 140B are in the assembled position, similar to the housing 40 of the embodiment. In this housing 140, the first twisted wire portion side _10A1 of the twisted pair wire 10A is arranged in the first housing body 140A, and the second twisted wire portion side _10A2 is arranged in the second housing body 140B.

Furthermore, in the housing 140 of this modified example, like the housing 40 of the embodiment, a portion of the twisted wire pair 10A before folding is arranged between the first housing body 140A and the second housing body 140B before assembly, and the first housing body 140A and the second housing body 140B are assembled while rotating relative to each other, so that the twisted wire pair 10A is pushed and folded by the first housing body 140A and the second housing body 140B. Therefore, in the same manner as the housing 40 of the embodiment, the housing 140 rotates the second housing body 140B together with the wiring twisted wire portion, which becomes a part of the second twisted wire portion side _10A2 after folding back the twisted wire pair 10A, relative to the first housing body 140A between an open position of the first housing body 140A and the second housing body 140B where the wiring twisted wire portion is wired to the second housing body 140B, and a closed position of the first housing body 140A and the second housing body 140B as an assembly completion position. In other words, the housing 140 rotates the second housing body 140B relative to the first housing body 140A between the open position of the first housing body 140A and the second housing body 140B where the twisted wire pair 10A is not folded back and the closed position of the first housing body 140A and the second housing body 140B where the twisted wire pair 10A is folded back. The housing 140 has a main body hinge portion (hereinafter referred to as "first hinge portion") 140C between the first housing main body 140A and the second housing main body 140B, which is responsible for the relative rotation between them (FIGS. 11 to 15). Like the first hinge portion 40C in the embodiment, the first hinge portion 140C is provided at a position where the second housing main body 140B can be rotated relative to the first housing main body 140A between a closed position and an open position while a part of the twisted pair wire 10A is routed between the first housing main body 140A and the second housing main body 140B. Furthermore, like the first hinge portion 40C in the embodiment, the first hinge portion 140C is provided at a position where the axial direction of the rotation shaft is perpendicular to the wiring direction of the twisted wire pair 10A when the first housing body 140A and the second housing body 140B are in the open position and the second housing body 140B and a pressure portion _140D1 (cover member 140D) described later are in the open position. Here, a living hinge is used for the first hinge portion 140C.

The first housing body 140A of this modification has terminal accommodating chambers 141 for each terminal fitting 130, which are roughly divided into a first accommodating portion 141a for accommodating the pair of insulation displacement bodies 131, 131 and a second accommodating portion 141b for accommodating the terminal connecting portion 132, as in the first housing body 40A of the embodiment (FIGS. 11 to 15). In the first housing body 140A, the first twisted wire portion side _10A1 of the twisted pair wire 10A having the pair of insulation displacement bodies 131, 131 pressure-welded to the electric wire 10 is arranged, as in the first housing body 40A of the embodiment.

The first accommodating portion 141a of this modification may be a chamber formed for each terminal fitting 130, similar to the first accommodating portion 41a of the embodiment, or may be a chamber in which a pair of insulation displacement bodies 131, 131 of a plurality of terminal fittings 130 are collectively accommodated. Similarly to the first accommodating portion 41a of the embodiment, the first accommodating portion 141a of this modification accommodates the electric wire 10 on the first twisted wire portion side _10A1 of the twisted wire pair 10A that is pressure-welded to the pair of insulation displacement bodies 131, 131 when the first housing body 140A and the second housing body 140B are in the assembly completion position (closed position). Like the first accommodating portion 41a of the embodiment, this first accommodating portion 141a has an opening (hereinafter referred to as the "first opening") 141c for inserting the wiring twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back, and an opening (hereinafter referred to as the "second opening") 141d that is perpendicular to the first opening 141c and serves as an electric wire outlet for drawing out the first twisted wire portion side _10A1 to the outside of the housing 140 (FIGS. 11 to 15). However, the second opening 141d of this modification is formed to open in a direction perpendicular to the direction of fitting and connecting the terminal connecting portion 132 to the counterpart terminal connecting portion. Furthermore, the first accommodating portion 141a in this modified example has an opening (hereinafter referred to as the "third opening") 141e that is perpendicular to the first opening 141c and opposed to the second opening 141d with a gap therebetween, and that allows the fold point _10A3 side of the first twisted wire portion side _10A1 to be pulled out to the outside (FIGS. 11 to 15).

The second accommodating portion 141b in this modified example is formed for each terminal fitting 130, similar to the second accommodating portion 41b in the embodiment.

The second housing body 140B of this modification has an electric wire routing chamber 142 in which the second twisted wire portion side _10A2 of the twisted pair wire 10A is routed, similarly to the second housing body 40B of the embodiment (FIGS. 11 to 13 and 15). The electric wire routing chamber 142 has an opening (hereinafter referred to as a "first opening") 142a for inserting the routed twisted wire portion that becomes the second twisted wire portion side _10A2 of the twisted pair wire 10A after folding back, and an opening (hereinafter referred to as a "second opening") 142b as an electric wire outlet that is perpendicular to the first opening 142a and allows the second twisted wire portion side _10A2 to be pulled out of the housing 140 (FIGS. 11 to 13 and 15). However, the second opening 142b in this modified example is formed to open in a direction perpendicular to the direction in which the terminal connection portion 132 is fitted and connected to the counterpart terminal connection portion.

In the housing 140 of this modified example, similarly to the housing 40 of the embodiment, when the first housing body 140A and the second housing body 140B are in the completed assembly position (closed position), the first accommodating portion 141a of the terminal accommodating chamber 141 and the wire routing chamber 142 are arranged opposite each other via their first openings 141c, 142a, while the second openings 141d, 142b open in a direction perpendicular to the mating connection direction of the terminal connection portion 32 (Figures 10 and 111). Therefore, in this housing 140, when the first housing body 140A and the second housing body 140B are in the completed assembly position (closed position), the first twisted wire portion side _10A1 of the twisted pair wire 10A in the first accommodating portion 141a and the second twisted wire portion side _10A2 of the twisted pair wire 10A in the wire routing chamber 142 are accommodated in an opposing arrangement, and the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 are pulled out to the outside from the second openings 141d, 142b in a direction perpendicular to the mating connection direction of the terminal connection portion 132.

The housing 140 of this modification, like the housing 40 of the embodiment, has a pressure member 140D1 that is interposed between the first twisted wire portion _10A1 and the second twisted wire portion _10A2 of the twisted wire pair 10A in the folded-back shape in the assembled position (closed position) and applies pressure to the folding point _10A3 of the twisted wire pair _10A to maintain the folded-back shape of the twisted wire pair 10A (FIGS. 10, 12, and 14). The pressure member _140D1 is assembled to either the first housing body 140A or the second housing body 140B, like the pressure member _40D1 of the embodiment. In this modification, the pressure member _140D1 is assembled to the second housing body 140B. The housing 140 of this modification rotates the pressure member _140D1 relative to the second housing body 140B between a closed position where the pressure member _140D1 is disposed in the first opening 142a of the electric wire routing chamber 142 and an open position where the pressure member _140D1 opens the first opening 142a. Therefore, the housing 140 has a hinge portion (hereinafter referred to as the "second hinge portion") 140E between the second housing body 140B and the pressure member _140D1 , which is responsible for the relative rotation (FIGS. 10, 12, and 14). The second hinge portion 140E is molded integrally with the first housing body 140A, the second housing body 140B, etc. as a living hinge, in the same manner as the second hinge portion 40E of the embodiment.

The housing 140 of this modified example, like the housing 40 of the embodiment, further has an elastic deformation portion 140D2 that applies pressure to the turn-back point _10A3 of the twisted wire pair _10A from the pressure applying portion _140D1 by a resilient force accompanying elastic deformation (FIGS. 11, 12, 14, and 15).

The pressure applying portion _140D1 and the elastic deformation portion _140D2 are provided on the cover member 140D in the same manner as the housing 40 of the embodiment (FIGS. 10 to 12, 14 and 15). In the connector 120 and the electric wire with connector 2 of this modification, although not shown, it is preferable that the pressure applying portion _140D1 applies pressure to the turn-up point _10A3 and the pressure applying portion _140D1 presses the turn-up point _10A3 against the inner wall surface of the housing 140 in the same manner as the connector 20 and the electric wire with connector ₁ of the embodiment. For example, the pressure applying portion 140D1 presses the turn-up point _10A3 against the inner wall surface arranged opposite to the first opening 142a of the second housing main body 140B with a gap therebetween. However, the cover member 140D of this modification closes the first opening 142a of the electric wire routing chamber 142. Therefore, in the housing 140 of this modified example, the cover member 140D is rotated at the second hinge portion 140E between a closed position and an open position relative to the first opening 142a.

The cover member 140D of this modification has a rectangular flat main body _140D3 connected to the second housing body 140B via the second hinge portion 140E (FIGS. 11, 12, 14, and 15). In the cover member 140D shown here, a rectangular cantilevered piece formed by two notches in the main body _140D3 is used as the elastic deformation portion _140D2 , and the free end of this elastic deformation portion 140D2 is formed into a cylindrical shape with the axis extending in the direction of the side of the free end (FIG. ₁₂ ). In this cover member 140D, the cylindrical portion at the free end of the elastic deformation portion _140D2 is used as the pressure portion _140D1 . Here, the second hinge portion 140E is provided on the side of the main body _140D3 that is perpendicular to the side of the free end of the elastic deformation portion _140D2 . The pressure member _140D1 is provided such that its cylindrical axis faces the same direction as the rotation axis of the first hinge portion 140C when the first housing body 140A, the second housing body 140B, and the cover member 140D are all in the assembly completion position (closed position).

In the connector 120 and the electric wire with connector 2 of this modified example, when the first housing body 140A and the second housing body 140B are in the open position and the second housing body 140B and the pressure portion _140D1 (cover member 140D) are in the open position, the wiring twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back is accommodated in the first accommodating portion 141a of the terminal accommodating chamber 141, and the wiring twisted wire portion that becomes the second twisted wire portion side _10A2 of the twisted pair wire 10A after folding back is accommodated in the electric wire wiring chamber 142, and a portion of the twisted pair wire 10A is routed between the first housing body 140A and the second housing body 140B ( FIGS. 12 and 13 ). At this time, in the first accommodating portion 141a, the pair of pressure contact bodies 131, 131 of the terminal fitting 130 are pressure-welded to the arranged twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back. Thereafter, in the connector 120 and the connector-attached electric wire 2, the pressure member _140D1 (the cover member 140D) is rotated to the closed position relative to the second housing body 140B around the second hinge portion 140E (FIGS. 14 and 15). Then, in the connector 120 and the connector-attached electric wire 2, the second housing body 140B and the pressure member _140D1 (the cover member 140D) are rotated to the closed position relative to the first housing body 140A together with the twisted pair wire 10A around the first hinge portion 140C (FIGS. 10 and 11). As a result, in the connector 120 and the electric wire with connector 2 of this modified example, the twisted pair wire 10A is folded back starting from the folding back point _10A3 pressed by the pressing portion _140D1 . Here, the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 of the folded back twisted pair wire 10A are drawn out in a direction perpendicular to the fitting connection direction of the terminal connection portion 32 to the mating terminal connection portion.

As described above, in the connector 120 and the electric wire with connector 2 of this modified example, similarly to the connector 20 and the electric wire with connector 1 of the embodiment, the twisted pair wire 10A is accommodated in the housing 140 while the folded shape is maintained by the pressure applying portion _140D1 , so that the twist of the two electric wires 10 of the twisted pair wire 10A is difficult to untwist, and deterioration of communication performance can be suppressed.

Furthermore, in the connector 120 and the electric wire with connector 2 of this modified example, as in the connector 20 and the electric wire with connector 1 of the embodiment, when the pressure applying portion _140D1 applies pressure to the folding point _10A3 , the reaction force received by the pressure applying portion _{140D1 from} the folding point 10A3 can be absorbed by the elastic deformation portion _140D2 . Therefore, it is possible to suppress untwisting of the twisted pair wire 10A while ensuring the durability of the twisted pair wire _10A , the pressure applying portion 140D1, and the second hinge portion 140E, and thereby suppress deterioration of communication performance.

Furthermore, in the connector 120 and the electric wire with connector 2 of this modified example, like the connector 20 and the electric wire with connector 1 of the embodiment, the pressure applying portion _140D1 has an arcuate surface along which the fold point _10A3 is aligned, and the curvature of the arcuate surface is set to a value that does not generate excessive bending stress at the fold point _10A3 , thereby suppressing deterioration in durability and communication performance.

[Modification 2]
17 to 20, reference numeral 3 denotes a connector-attached electric wire of this modified example. This connector-attached electric wire 3 is obtained by replacing the connector 20 in the connector-attached electric wire 1 of the above-described embodiment with a connector 220 described below.

The connector 220 of this modified example has a terminal fitting 230 and a housing 240, similar to the connector 20 of the embodiment (Figures 18 to 20).

The terminal fitting 230 of this modification has a pair of insulation displacement bodies 231, 231 and a terminal connection portion 232 similar to those of the terminal fitting 30 of the embodiment (FIGS. 18 and 20). Like the terminal fitting 30 of the embodiment, this terminal fitting 230 is formed so that the first twisted wire portion side 10A _-1 and the second twisted wire portion side 10A- ₂ of the twisted pair wire 10A are pulled out from the housing 240 in a direction opposite to the mating connection direction of the terminal connection portion 232. Therefore, in the connector-attached electric wire 3 of this modification, like the connector-attached electric wire 1 of the above-described embodiment, the pulling direction of the twisted pair wire 10A pulled out from the trunk wire (not shown) is the mating connection direction of the connector 220.

The terminal fitting 230 of this modified example also has a flat connecting portion 233 that connects the pair of pressure-contact bodies 231, 231 and the terminal connection portion 232, just like the terminal fitting 30 of the embodiment, but unlike the terminal fitting 30, the pair of pressure-contact bodies 231, 231 and the terminal connection portion 232 protrude in the same direction when viewed from the connecting portion 233 (Figures 18 and 20). Here, the pair of pressure-contact bodies 231, 231 and the terminal connection portion 232 protrude in the same direction from one flat surface of the connecting portion 233.

The housing 240 of this modification has a first housing body 240A and a second housing body 240B that are assembled to each other, similar to the housing 40 of the embodiment (FIGS. 17 to 20). However, in the housing 240 of this modification, the twisted pair 10A is accommodated in the second housing body 240B in a folded state. In other words, the second housing body 240B of this modification accommodates the twisted pair 10A folded back from a folding point _10A3 to a first twisted wire section side _10A1 and a second twisted wire section side _10A2 , and is assembled to the first housing body 240A with the folded twisted pair 10A accommodated therein. In the housing 240 of this modified example, a second housing body 240B in which the twisted pair wire 10A is housed is assembled to a first housing body 240A, whereby a pair of insulation displacement bodies 231, 231 are pressure-welded to the wire 10 on the first twisted wire portion side 10A1 of the twisted pair wire _10A .

Specifically, the first housing body 240A of this modification has terminal accommodating chambers 241 for each terminal fitting 230, which are broadly divided into a first accommodating portion 241a that accommodates a pair of pressure contact bodies 231, 231, and a second accommodating portion 241b that accommodates a terminal connection portion 232, as in the first housing body 40A of the embodiment (FIGS. 18 to 20). However, in the terminal accommodating chambers 241 of this modification, the terminal fittings 230 for each electric wire 10 of the twisted pair wire 10A are accommodated side by side with the pair of pressure contact bodies 231, 231 exposed.

The first accommodating portion 241a of this modification is formed as a chamber that accommodates the pair of insulation displacement bodies 231, 231 of the terminal fittings 230 for each electric wire 10 of the twisted pair wire 10A in an exposed state together (FIG. 19). The housing 240 of this modification has a second housing body 240B assembled into the first accommodating portion 241a, whereby the pair of insulation displacement bodies 231, 231 are pressure-welded to the electric wire 10 on the first twisted wire portion side _10A1 of the twisted pair wire 10A in the second housing body 240B.

The second accommodating portion 241b in this modified example is formed for each terminal fitting 230, similar to the second accommodating portion 41b in the embodiment.

The second housing body 240B of this modification has a first electric wire routing section _240B1 in which the first twisted wire portion _10A1 of the twisted pair wire 10A is routed, and a second electric wire routing section _240B2 which is assembled to the first electric wire routing section _240B1 and in which the second twisted wire portion _10A2 of the twisted pair wire 10A is routed (FIGS. 17 to 25). In the second housing body 240B, when the first electric wire routing section _240B1 and the second electric wire routing section _240B2 are in the assembly completion position, the twisted pair wire 10A is folded back in a U-shape starting from the folding back point _10A3 (FIGS. 17 to 20).

In the second housing body 240B, a portion of the twisted pair wire 10A before being folded back is routed between the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 before being assembled, and the twisted pair wire 10A is folded back in conjunction with the assembly operation of the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 . Here, the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 are assembled while being rotated relative to each other, so that the twisted pair wire 10A is pushed and folded back by the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 . This second housing body 240B rotates the second electric wire routing portion 240B2 together with the routing and twisted wire portion relative to the first electric wire routing portion _240B1 between an open position of the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 , in which the routing and twisted wire portion that becomes part of the first twisted wire portion side _10A1 after folding back in the twisted pair wire _10A is routed to the first electric wire routing portion _240B1 , and a closed position of the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 , which is an assembly completion position. That is, the second housing main body 240B rotates the first electric wire routing portion _240B1 relative to the second electric wire routing portion _240B2 between an open position of the first electric wire routing portion 240B1 and the second electric wire routing portion 240B2 in which the twisted pair wire 10A is not folded back and a closed position of the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 in which the twisted pair wire _10A is folded back. Therefore, the second housing main body 240B has a hinge portion (hereinafter referred to as a _" first hinge portion") _240B3 between the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 for controlling the relative rotation (FIGS. 18 and 20 to 25). The first hinge portion _240B3 is provided at a position where the second electric wire routing portion _240B2 can rotate relative to the first electric wire routing portion _240B1 between the closed position and the open position while a part of the twisted pair wire _10A is routed between the first electric wire routing portion 240B1 and the second electric wire routing portion _240B2 . Here, a living hinge is used for the first hinge portion _240B3 .

In this second housing body 240B, the first twisted wire portion side _10A1 of the twisted pair wire 10A is routed in a first wire routing chamber 242 of the first wire routing portion _240B1 , and the second twisted wire portion side _10A2 of the twisted pair wire 10A is routed in a second wire routing chamber 243 of the second wire routing portion _240B2 (FIGS. 17 to 25).

In the first electric wire routing chamber 242, the routed twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back is inserted through an opening (hereinafter referred to as the "first opening") 242a (FIGS. 21 to 23). The first twisted wire portion side _10A1 of the twisted pair wire 10A is pulled out of the first electric wire routing chamber 242 through an opening (hereinafter referred to as the "second opening") 242b that is perpendicular to the first opening 242a (FIGS. 17 to 20). The second opening 242b is used as an electric wire outlet for pulling out the first twisted wire portion side _10A1 to the outside of the housing 240.

In the second electric wire routing chamber 243, the routed twisted wire portion that becomes the second twisted wire portion side _10A2 of the twisted pair wire 10A after folding back is inserted through an opening (hereinafter referred to as the "first opening") 243a (FIGS. 21 to 23). The second twisted wire portion side _10A2 of the twisted pair wire 10A is pulled out of the second electric wire routing chamber 243 through an opening (hereinafter referred to as the "second opening") 243b that is perpendicular to the first opening 243a (FIGS. 17 to 20). The second opening 243b is used as an electric wire outlet for pulling out the second twisted wire portion side _10A2 to the outside of the housing 240.

In this second housing body 240B, when the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 are in the assembly completion position (closed position), the first electric wire routing chamber 242 and the second electric wire routing chamber 243 are arranged opposite each other via the first openings 242a, 243a, and the second openings 242b, 243b open in the same direction (FIGS. 17 to 20). Therefore, in this second housing main body 240B, when the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 are in the assembly completion position (closed position), the first twisted wire portion side _10A1 of the twisted pair wire 10A in the first electric wire routing chamber 242 and the second twisted wire portion side _10A2 of the twisted pair wire 10A in the second electric wire routing chamber 243 are accommodated in an opposing arrangement state, and the first twisted wire portion side _10A1 and the second twisted wire portion side _10A2 are pulled out to the outside from the second openings 242b, 243b in the same direction. The second housing main body 240B shown here is assembled to the first accommodation portion 241a of the first housing main body 240A so that the second openings 242b, 243b open in the opposite direction to the fitting connection direction of the terminal connection portion 232 to the counterpart terminal connection portion.

Furthermore, the second housing body 240B has a pressure member 240B41 which is interposed between the first twisted wire portion _10A1 and the second twisted wire portion _10A2 of the folded twisted wire pair 10A in the assembled position (closed position) and applies pressure to the folding point _10A3 of the twisted wire pair 10A to maintain the folded shape of the twisted wire pair _10A (FIGS. 18 and 20 to 25). The pressure member _240B41 is assembled to the first wire routing portion _240B1 . The second housing main body 240B shown here has a hinge portion (hereinafter referred to as the "second hinge portion") _240B5 that rotates the pressure portion 240B41 relative to the first wire routing portion _240B1 between a closed position where the pressure portion _240B41 is disposed in the first opening _242a of the first wire routing chamber 242 and an open position where the pressure portion 240B41 opens the first opening _242a (FIG. 21). Here, a living hinge is used for the second hinge portion _240B5 .

The pressure member _240B41 is provided on the cover member _240B4 together with an elastic deformation member _240B42 that applies pressure to the turn-back point _10A3 of the twisted wire pair 10A from the pressure member _240B41 by a resilient force caused by elastic deformation, similar to the pressure member _40D1 of the embodiment (FIGS. 18, 20, 21, 24, and 25). The cover member _240B4 of this modification is a member for closing the first opening 242a of the first wire routing chamber 242, and has a rectangular flat main body _240B43 connected to the second hinge portion _240B5 (FIGS. 17 to 21, 24, and 25). The second hinge portion _240B5 shown here is provided between the first electric wire routing portion _240B1 and one side of the main body _240B43 at a position where the axial direction of its rotation shaft is perpendicular to the axial direction of the rotation shaft of the first hinge portion _240B3 . The cover member _240B4 shown here is formed in the same manner as the cover member 40D of the embodiment. In the connector 220 and the connector-attached electric wire 3 of this modified example, as in the connector 20 and the connector-attached electric wire 1 of the embodiment, it is desirable that the pressure portion _240B41 applies pressure to the folding point _10A3 and that the pressure portion _240B41 presses the folding point _10A3 against the inner wall surface of the second housing main body 240B. For example, the pressure member _240B41 presses the folding point _10A3 against an inner wall surface arranged opposite to and spaced from the first opening 243a of the second electric wire routing portion _240B2 of the second housing body 140B (FIG. 18).

In the housing 240 of this modification, by assembling the second housing body 240B into the first accommodating portion 241a of the first housing body 240A, the pair of insulation displacement bodies 231, 231 of the first accommodating portion 241a are brought into pressure contact with the electric wire 10 in the first electric wire routing chamber 242 of the first electric wire routing portion 240B _1. For this reason, the first electric wire routing portion 240B ₁ is formed so that, when the first housing body 240A and the second housing body 240B are in an assembly completion position, the pair of insulation displacement bodies 231, 231 of the first accommodating portion 241a are inserted into the first electric wire routing chamber 242, and the pair of insulation displacement bodies 231, 231 are brought into pressure contact with the electric wire 10 on the first twisted wire portion side 10A ₁ of the twisted pair wire 10A in the first electric wire routing chamber 242.

For example, the first electric wire routing portion 240B1 is provided with insertion holes 244 for inserting the pair of insulation displacement bodies 231, 231 into the first electric wire routing chamber 242 when the first housing body 240A and the second housing body 240B are in _the assembly completion position (FIGS. 18, 20, 22, 23, and 25). The insertion holes 244 may be through holes provided for each terminal fitting 230, or may be a single through hole for inserting the pair of insulation displacement bodies 231, 231 of the multiple terminal fittings 230. The insertion hole 244 shown here is provided in a wall of the first electric wire routing portion _240B1 that faces the cover member _240B4 with a gap therebetween when the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 are in the assembly completion position (closed position).

Furthermore, the second housing body 240B is provided with holding portions 245 for holding the electric wire 10 on the first twisted wire portion side _10A1 of the twisted pair wire 10A at a distance in the axial direction in the first electric wire routing chamber 242 (FIGS. 18, 20 to 23, and 25). In this second housing body 240B, the electric wire 10 is held by a pair of holding portions 245 arranged at a distance from each other in the axial direction of the electric wire 10. In this second housing body 240B, a pair of pressure contact bodies 231, 231 inserted into the first electric wire routing chamber 242 is inserted between the pair of holding portions 245, and the pair of pressure contact bodies 231, 231 are pressure-contacted to the electric wire 10 between the pair of holding portions 245. The pair of holding portions 245 is provided for each electric wire 10 on the first twisted wire portion side _10A1 . The pair of holding portions 245 are disposed with the insertion hole 244 therebetween.

For example, the holding portion 245 shown here includes a first holding portion 245a provided on the first wire routing portion _240B1 and a second holding portion 245b provided on the main body _240B43 of the cover member _240B4 (FIGS. 18, 20 to 23, and 25). When the cover member _240B4 is in a closed position relative to the first opening 242a, the holding portion 245 sandwiches and holds the routing twisted wire portion, which becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back, between the first holding portion 245a and the second holding portion 245b. The holding portion 245 shown here includes a pair of first holding portions 245a spaced apart from each other to insert the electric wire 10 therebetween, and a second holding portion 245b that is inserted between the pair of first holding portions 245a when the cover member _240B4 is in a closed position relative to the first opening 242a, and that sandwiches the electric wire 10 between the pair of first holding portions 245a together with the pair of first holding portions 245a. The pair of first holding portions 245a are provided on a wall of the first electric wire routing portion _240B1 in which the insertion hole 244 is formed.

In this connector 220 and connector-attached electric wire 3, when the first electric wire routing portion _240B1 and the second electric wire routing portion _240B2 are in the open position and the first electric wire routing portion _240B1 and the pressure portion _240B41 (cover member _240B4 ) are in the open position, the wiring and twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back is accommodated in the first electric wire routing chamber 242 of the first electric wire routing portion _240B1 , and the wiring and twisted wire portion that becomes the second twisted wire portion side _10A2 of the twisted pair wire 10A after folding back is accommodated in the second electric wire routing chamber 243 of the second electric wire routing portion _240B2 , so that a part of the twisted pair wire 10A is arranged between the first electric wire routing portion _240B1 and the second electric wire routing portion 240B4. ₂ (FIGS. 21 to 23). Thereafter, in the connector 220 and the connector-attached electric wire 3, the pressing portion _240B41 (cover member _240B4 ) is rotated relative to the first electric wire routing portion _240B1 to the closed position with the second hinge portion _240B5 as the center of rotation (FIGS. 24 and 25). As a result, in the second housing main body 240B, the routing twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after folding back is held by the holding portion 245.

Next, in the connector 220 and the connector-attached electric wire ₃ , the second electric wire routing portion _240B2 together with the twisted pair wire 10A is rotated relative to the first electric wire routing portion _240B1 and the pressure portion _240B41 (cover member _240B4 ) to the closed position with the first hinge portion 240B3 as the rotation center (FIGS. 19 and 20). As a result, in the second housing body 240B, the twisted pair wire 10A is folded back starting from the folding point _10A3 pressed by the pressure portion _240B41 .

In the connector 220 and the electric wire with connector 3, the second housing body 240B is assembled into the first accommodating portion 241a of the first housing body 240A (FIGS. 17 to 20). Accordingly, in the connector 220 and the electric wire with connector 3, the pair of pressure contact bodies 231, 231 of the terminal fitting 230 exposed in the first accommodating portion 241a enters the first electric wire routing chamber 242 of the first electric wire routing portion _240B1 through the insertion hole 244, and the pair of pressure contact bodies 231, 231 are pressure-welded to the electric wire 10 on the first twisted wire portion side 10A1 of the twisted pair wire _10A held by the holding portion 245 in the first electric wire routing chamber 242. In the connector 220 and the electric wire with connector 3 of this modified example, the assembly is completed in this manner.

As described above, in the connector 220 and the electric wire with connector 3 of this modified example, similarly to the connector 20 and the electric wire with connector 1 of the embodiment, the twisted pair wire 10A is accommodated in the housing 240 while the folded shape is maintained by the pressure applying portion 240B ₄₁ , so that the twist of the two electric wires 10 of the twisted pair wire 10A is difficult to untwist, and deterioration of communication performance can be suppressed.

Furthermore, in the connector 220 and the electric wire with connector 3 of this modified example, as in the connector 20 and the electric wire with connector 1 of the embodiment, when the pressure applying portion _240B41 applies pressure to the turn-around point _10A3 , the reaction force received by the pressure applying portion _240B41 from the turn-around point _10A3 can be absorbed by the elastic deformation portion _240B42 . Therefore, it is possible to suppress untwisting of the twisted pair wire 10A while ensuring the durability of the twisted pair wire 10A, the pressure applying portion _240B41 , and the second hinge portion _240B5 , and thereby suppress deterioration of communication performance.

Furthermore, in the connector 220 and the electric wire with connector 3 of this modified example, like the connector 20 and the electric wire with connector 1 of the embodiment, the pressure applying portion _240B41 has an arcuate surface along which the fold point _10A3 is aligned, and the curvature of the arcuate surface is set to a value that does not generate excessive bending stress at the fold point _10A3 , thereby suppressing deterioration in durability and communication performance.

[Modification 3]
Reference numeral 4 in Fig. 26 denotes a connector-equipped electric wire of this modified example. This connector-equipped electric wire 4 is obtained by replacing the connector 220 in the connector-equipped electric wire 3 of the modified example 2 described above with a connector 320 described below. The connector 320 of this modified example is obtained by replacing the housing 240 in the connector 220 of the modified example 2 with a housing 340 described below. The terminal fittings 230 are omitted in the figure. The housing 340 of this modified example is obtained by replacing the second housing main body 240B in the housing 240 of the modified example 2 with a second housing main body 340B described below.

The second housing body 340B of this modification, like the second housing body 240B of the modification 2, _has a first electric wire routing section 340B1 in which the first twisted wire portion side _10A1 of the twisted pair wire 10A is routed, and a second electric wire routing section 340B2 which is assembled to the first electric wire routing section _340B1 and in _which the second twisted wire portion side _10A2 of the twisted pair wire 10A is routed (FIGS. 26 to 28). In this second housing body 340B, when the first electric wire routing section _340B1 and the second electric wire routing section _340B2 are in the assembly completion position, the twisted pair wire 10A is folded back in a U-shape starting from the folding point _10A3 . Furthermore, in the second housing body 340B of this modified example, like the second housing body 240B of modified example 2, the second electric wire routing portion 340B2 rotates relative to the first electric wire routing portion _340B1 together with the routing and twisted wire portion between an open position of _the first electric wire routing portion _340B1 and the second electric wire routing portion _340B2 in which the routing and twisted wire portion that becomes part of the first twisted wire portion side _10A1 after folding back the twisted pair wire 10A is routed to the first electric wire routing portion _340B1 and a closed position of the first electric wire routing portion _340B1 and the second electric wire routing portion _340B2 as an assembly completion position. That is, like the second housing body 240B of the second modification, the second housing body 340B has a hinge portion (hereinafter referred to as a "first hinge portion") _340B3 that rotates the second electric wire routing portion 340B2 relative to the first electric wire routing portion _340B1 between an open position of the first electric wire routing portion _340B1 and the _second electric wire routing portion _340B2 in which the twisted pair wire 10A is not folded back and a closed position of the first electric wire routing portion _340B1 and the second electric wire routing portion 340B2 in which the twisted pair wire _10A is folded back (FIGS. 27 and 28). Here, a living hinge is used for the first hinge portion _340B3 .

In this second housing body 340B, like the second housing body 240B of the modified example 2, the first twisted wire portion side _10A1 of the twisted pair wire 10A is routed in a first wire routing chamber 342 of the first wire routing portion _340B1 , and the second twisted wire portion side _10A2 of the twisted pair wire 10A is routed in a second wire routing chamber 343 of the second wire routing portion _340B2 (FIGS. 27 and 28). However, in this second housing body 340B, the second wire routing portion _340B2 is formed as equivalent to the second wire routing portion _240B2 of the modified example 2, while the first wire routing portion _340B1 is formed as different from the first wire routing portion _240B1 of the modified example 2.

The first electric wire routing portion _340B1 of this modified example has a base portion _340B11 and first to fourth cantilevered protrusions _{340B12-340B15} protruding in the same direction from the base portion _340B11 along the axial direction of the first hinge portion _340B3 ( _FIGS . 27 and 28).

The first protrusion _340B12 and the second protrusion _340B13 are disposed opposite each other with a gap therebetween in a direction perpendicular to the protruding direction of the first protrusion 340B12 and the wiring direction of the twisted pair wire 10A before being folded back, and hold two electric wires 10 of the twisted pair wire 10A inserted into the gap from the openings on the free end side of each protrusion (FIGS. 27 and 28). The first protrusion _340B12 and the second protrusion _340B13 are formed so that the gap is equal to the diameter of the electric wires 10.

The third protrusion _340B14 and the fourth protrusion _340B15 are formed in the same manner as the combination of the first protrusion _340B12 and the second protrusion _340B13 , and are disposed opposite to and spaced apart from the combination of the first protrusion _340B12 and the second protrusion _340B13 on the first hinge portion _340B3 side (FIGS. 27 and 28).

In the first electric wire routing portion 340B _-1 , a space extending from the gap between the first protrusion 340B- ₁₂ and the second protrusion 340B- ₁₃ to the gap between the third protrusion 340B- ₁₄ and the fourth protrusion 340B- ₁₅ forms a first electric wire routing chamber 342.

Furthermore, the fourth protrusion _340B15 is interposed between the first twisted wire portion _10A1 and the second twisted wire portion _10A2 of the folded twisted pair wire 10A when the first electric wire routing portion _340B1 and the second electric wire routing portion 340B2 are in the assembled position (closed position) and is also used as a pressure applying portion _340B4 that applies pressure to the folding point _10A3 of the twisted pair wire 10A to maintain the folded shape of the twisted pair wire 10A ( _FIGS . 27 and 28). Therefore, the outer wall surface of the fourth protrusion _340B15 on the opposite side to the third protrusion _340B14 is formed as an arcuate surface with its own protruding direction as its axis.

In the first electric wire routing portion _340B1 , the electric wires 10 of the twisted pair wire 10A inserted from each opening are guided and inserted one by one between the first protrusion _340B12 and the second protrusion _340B13 and between the third protrusion _340B14 and the fourth protrusion _340B15 . For this reason, in the first electric wire routing portion _340B1 , tapered portions 344a whose spacing becomes wider toward the opening are provided between the free end sides of the first protrusion _340B12 and the second protrusion _340B13 , and tapered portions 344b whose spacing becomes wider toward the opening are provided between the free end sides of the third protrusion _340B14 and the fourth protrusion _340B15 (FIGS. 27 to 29). As a result, in the first wire routing portion 340B _-1 , the electric wires 10 of the twisted pair 10A inserted from each opening can be guided by each tapered portion 344a, 344b and inserted one by one between the first protruding portion 340B- ₁₂ and the second protruding portion 340B- ₁₃ and between the third protruding portion 340B- ₁₄ and the fourth protruding portion 340B- ₁₅ ( FIG. 29 ).

In the first electric wire routing portion 340B _-1 , the two electric wires 10 of the twisted pair wire 10A are inserted into the gaps between the openings of the first protrusion 340B- ₁₂ and the second protrusion 340B- ₁₃ , and the two electric wires 10 of the twisted pair wire 10A are inserted into the gaps between the openings of the third protrusion 340B- ₁₄ and the fourth protrusion 340B- ₁₅ . Accordingly, in the first electric wire routing portion 340B _-1 , the two electric wires 10 of the twisted pair wire 10A are arranged along the insertion direction between the first protrusion 340B- ₁₂ and the second protrusion 340B- ₁₃ and the third protrusion 340B- ₁₄ and the fourth protrusion 340B _-15 . In the first wire routing portion 340B _-1 , the routing twisted wire portion which becomes the first twisted wire portion side 10A- ₁ of the twisted pair wire _{10A after folding back is held in the gap between the first protrusion 340B-12 and} the second protrusion 340B-13 and the gap between the third protrusion 340B _-14 and the fourth protrusion 340B- ₁₅ .

In this connector 320 and connector-attached electric wire 4, when the first electric wire routing portion _340B1 and the second electric wire routing portion _340B2 are in the open position, the wiring and twisted wire portion that becomes the first twisted wire portion side _10A1 of the twisted pair wire 10A after being folded back is accommodated in the first electric wire routing chamber 342 of the first electric wire routing portion _340B1 , and the wiring and twisted wire portion that becomes the second twisted wire portion side _10A2 of the twisted pair wire 10A after being folded back is accommodated in the second electric wire routing chamber 343 of the second electric wire routing portion _340B2 , and a part of the twisted pair wire 10A is routed between the first electric wire routing portion _340B1 and the second electric wire routing portion _340B2 before assembly ( FIGS. 27 and 28 ). Thereafter, in the connector 320 and the connector-attached electric wire ₄ , the first electric wire routing portion _340B1 is rotated together with the twisted pair 10A relative to the second electric wire routing portion _340B2 to the closed position with the first hinge portion 340B3 as the rotation center (FIG. 26). As a result, in the second housing body 340B, the twisted pair 10A is folded back starting from the folding point _10A3 pressed by the pressing portion _340B4 .

In the connector 320 and the electric wire 4 with connector, the second housing body 340B is assembled into the first accommodating portion 241a of the first housing body 240A (FIG. 26). Accordingly, in the connector 320 and the electric wire 4 with connector, the pair of pressure contact bodies 231, 231 of the terminal fitting 230 exposed in the first accommodating portion 241a enters the first electric wire routing chamber 342 of the first electric wire routing portion _340B1 from between the first protruding portion _340B12 and the third protruding portion _340B14 , and the pair of pressure contact bodies 231, 231 are pressure-welded to the electric wire 10 on the first twisted wire portion side _10A1 of the twisted pair wire 10A in the first electric wire routing chamber 342. In the connector 320 and the electric wire 4 with connector of this modified example, the assembly is completed in this manner.

As described above, in the connector 320 and the electric wire with connector 4 of this modified example, similarly to the connector 220 and the electric wire with connector 3 of modified example 2, the twisted pair wire 10A is accommodated in the housing 340 while the folded shape is maintained by the pressure applying portion _340B4 , so that the twist of the two electric wires 10 of the twisted pair wire 10A is difficult to untwist, and deterioration of communication performance can be suppressed.

Furthermore, in the connector 320 and the electric wire with connector 4 of this modified example, like the connector 220 and the electric wire with connector 3 of modified example 2, the pressure applying portion _340B4 has an arcuate surface along which the fold point _10A3 is aligned, and the curvature of the arcuate surface is set to a value that does not generate excessive bending stress at the fold point _10A3 , thereby suppressing deterioration in durability and communication performance.
