Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, in order to meet the demand for shortening the length of connectors, for example, connectors have been developed in which electric wires are bent and routed inside a housing. However, when the electric wires are bent in a limited space, there is a concern that, for example, when the electric wires include power lines and signal lines, the power lines and the signal lines are likely to be close to each other. When the power lines and the signal lines are close to each other, there is a risk that the transmission characteristics will deteriorate.

The dielectric material has a first cavity in which the first terminal fitting is housed, and a second cavity located below the first cavity in which the second terminal fitting is housed. The first electric wire, which is led out from the rear end of the first cavity into the wiring space, has a first bent portion in which the portion leading to the leading direction of the lead-out is bent in a direction that intersects with the insertion direction of the dielectric into the module housing chamber within the wiring space. The second electric wire, which is led out from the rear end of the second cavity into the wiring space, has a second bend that is bent in the same direction as the first bend, A connector in which the rear end of the first cavity is located further back than the rear end of the second cavity.

[0008] [Description of Embodiments in this Disclosure]

[0009] (1) The connector of the present disclosure comprises a housing having a module housing chamber and a cable routing space communicating with the rear end of the module housing chamber, and a terminal module inserted into the module housing chamber from the rear. The terminal module has a first wire, a first terminal fitting fixed to the first wire, a second wire, a second terminal fitting fixed to the second wire, and a dielectric housed in the module housing chamber. The dielectric has a first cavity housing the first terminal fitting and a second cavity located below the first cavity housing the second terminal fitting. The first wire, led out from the rear end of the first cavity into the cable routing space, has a first bend portion in which the portion leading to the leading end in the leading direction is bent in the cable routing space in a direction intersecting the direction in which the dielectric is inserted into the module housing chamber. The second wire, led out from the rear end of the second cavity into the cable routing space, has a second bend portion bent in the same direction as the first bend portion. The rear end of the first cavity is located further back than the rear end of the second cavity.

[0010] Since the rear end of the first cavity is located behind the rear end of the second cavity, in the wiring space, the first electric wire having the first bent portion and the second electric wire having the second bent portion can be easily wired with a space in the front-rear direction. Thereby, deterioration of transmission characteristics due to the proximity of the first electric wire and the second electric wire in the housing can be suppressed. In the present specification, the "same direction" includes not only the case of facing exactly the same direction, but also a slightly deviated direction as long as the above-described effects can be achieved even if it is not exactly the same direction.

[0011] (2) In the connector according to (1), it is preferable that the second cavity is shorter in length in the front-rear direction than the first terminal fitting.

[0012] According to this configuration, when trying to accommodate the first terminal fitting in the second cavity, a part of the first terminal fitting protrudes from the second cavity, so that it can be prevented that the first terminal fitting is accidentally accommodated in the second cavity.

[0013] (3) In the connector according to (1) or (2), the first electric wire extends downward from the first bent portion in the wiring space, the second electric wire extends from the second bent portion in the wiring space in the same direction as the first bent portion, and in the wiring space, it is preferable that the first electric wire and the second electric wire are wired with a space in the left-right direction.

[0014] According to this configuration, the first electric wire and the second electric wire are wired with a space not only in the front-rear direction but also in the left-right direction. Compared with the case where the first electric wire and the second electric wire are wired without a space in the left-right direction, a larger space between the first electric wire and the second electric wire can be secured in the wiring space. Therefore, deterioration of transmission characteristics can be effectively suppressed without increasing the front-rear dimension of the wiring space.

[0015] (4) In the connector according to (3), an elastic member for closing the opening at the end of the wiring space on the side opposite to the module accommodation chamber is further provided, and the elastic member has a first seal hole through which the first electric wire passes and a second seal hole through which the second electric wire passes. It is preferable that the first seal hole and the second seal hole are arranged at intervals in the left-right direction.

[0016] According to this configuration, by inserting the first electric wire and the second electric wire into the first seal hole and the second seal hole of the elastic member, the first electric wire and the second electric wire are held in a position relationship separated left and right in the wiring space. Therefore, deterioration of transmission characteristics due to the proximity of the first electric wire and the second electric wire can be prevented.

[0017] (5) In the connector according to (1) or (2), the first electric wire extends laterally from the first bent portion in the wiring space, and the second electric wire extends from the second bent portion in the wiring space in the same direction as the first bent portion. In the wiring space, it is preferable that the first electric wire and the second electric wire are wired at intervals in the vertical direction.

[0018] According to this configuration, the first electric wire and the second electric wire are wired at intervals not only in the front-rear direction but also in the vertical direction. Compared with the case where the first electric wire and the second electric wire are not spaced apart in the vertical direction, a larger interval between the first electric wire and the second electric wire can be ensured in the wiring space. Therefore, deterioration of transmission characteristics can be effectively suppressed without increasing the size of the wiring space in the front-rear direction.

[0019] (6) In the connector according to (5), an elastic member for closing the opening at the end of the wiring space on the side opposite to the module accommodation chamber is further provided, and the elastic member has a first seal hole through which the first electric wire passes and a second seal hole through which the second electric wire passes. It is preferable that the first seal hole and the second seal hole are arranged at intervals in the vertical direction.

[0020] With this configuration, by inserting the first and second wires through the first and second sealing holes of the elastic member, the first and second wires are maintained in a vertically separated positional relationship within the wiring space, thereby preventing deterioration of transmission characteristics caused by the first and second wires being in close proximity.

Each of the four openings communicates with an insertion hole 43 of the lower dielectric 35.

[0045] <Effects of Connector 10> The connector 10 is assembled in the following steps. First, the connecting rod 73 of the bottom cover 70 is attached to the rubber stopper 80. Connection hole 84 Insert it through and connect the two. At this time, the first guide hole 75 and First sealing hole 83 They are connected. 2nd guide hole 74 and, Second sealing hole 82 They are in communication. Next, the two first electric wires 90 are inserted from below through the first guide hole 75 and the first seal hole 83. Next, the sheath 25 covering the two second electric wires 100 is inserted through the second guide hole 74 and the second seal hole 82. At this time, the two first electric wires 90 are positioned to the left of the sheath 25. The two second electric wires 100 are twisted together in the portion covered by the sheath 25 to form a twisted pair wire.

[0046] Next, the first terminal fitting 55A and the first electric wire 90, and, Second terminal fitting 55B The first terminal fitting 55A and the second wire 100 are connected. The first terminal fitting 55A and the first wire 90 are connected by crimping the front end of the first wire 90 to the first crimping section 56A. Similarly, the second terminal fitting 55B and the second wire 100 are connected by crimping the front end of the second wire 100 to the second crimping section 56B.

[0047] Next, the terminal module 30A is assembled. As shown in Figure 11, the second terminal fitting 55B is fitted from above into a pair of second cavities 31 formed in the lower dielectric 35. Specifically, the second terminal body 38 is housed in the second engagement recess 39 formed on the bottom surface of the second cavity 31. Since the vertical and horizontal widths of the second engagement recess 39 are approximately the same as the vertical and horizontal widths of the second terminal body 38, the movement of the second terminal body 38 in the front, back, left, and right directions is restricted.

[0048] Furthermore, the middle dielectric 45 is mounted on top of the lower dielectric 35, which has the second terminal fitting 55B attached. Specifically, the lower engaging portion 40 of the lower dielectric 35 and the engaging portion (not shown) of the middle dielectric 45 are fitted together. Next, the first terminal fitting 55A is housed in a pair of first cavities 46 formed in the middle dielectric 45. Specifically, the first positioning projection 54 formed on the first terminal body 57 is housed in the first positioning recess 44 formed on the bottom surface of the first cavity 46. Since the vertical and horizontal widths of the first positioning recess 44 and the vertical and horizontal widths of the first positioning projection 54 are approximately the same, the vertical and horizontal movement of the first terminal body 57 is restricted. Next, the dielectric cover 65 is mounted from above the middle dielectric 45. Specifically, the dielectric cover 65 is fitted to the middle dielectric 45 via the first engaging portion and to the lower dielectric 35 via the second engaging portion. This forms a dielectric 30 that holds the first terminal fitting 55A and the second terminal fitting 55B.

[0049] As shown in Figure 12, if, during the assembly of the terminal module 30A, the first terminal fitting 55A is mistakenly inserted into the second cavity 31, the length of the second cavity 31 in the front-to-back direction will be shorter than the length of the first terminal fitting 55A in the front-to-back direction, and the rear end of the first terminal fitting 55A will be Second Cavity 31 Because it protrudes from the rear end surface 31S, incorrect assembly can be easily detected.

[0050] Furthermore, the length 39D of the second engagement recess 39 in the front-rear direction is shorter than the front-rear dimension from the front end of the first terminal body 57 to the first positioning projection 54 located at the rear end of the first terminal body 57. Therefore, if the above incorrect assembly is attempted, the lower surface of the first positioning projection 54 will come into contact with the upper surface of the second projection 34. As a result, the first terminal body 57 of the first terminal fitting 55A will float up without being accommodated in the second engagement recess 39 of the second cavity 31, making it easy to detect incorrect assembly.

[0051] Next, as shown in Figure 2, the terminal module 30A is assembled into the housing 20. The terminal module 30A is inserted into the wiring space 12, for example, from the bottom opening 19. Then, the dielectric 30 of the terminal module 30A is inserted into the module housing chamber 11 from the rear of the housing 20. As shown in Figure 3, the dielectric 30 is pressed from below by the front end surface of the insertion portion 42 against the inclined portion of the plate-shaped portion 21. The pressed plate-shaped portion 21 elastically deforms upward. When the locking portion 64 of the dielectric cover 65 overcomes the front end surface 21S of the inclined portion of the plate-shaped portion 21, the plate-shaped portion 21 is no longer pressed from below and elastically deforms downward to return to its original state. At this time, the front end surface 21S of the inclined portion of the plate-shaped portion 21 and Locking part 64 The front end surface 64S comes into contact with the dielectric, restricting its forward and backward movement. In this way, the dielectric 30 is housed in the module housing chamber 11 with its movement restricted.

[0052] As shown in Figure 3, when the dielectric 30 is inserted into the module housing chamber 11, the end face 25S of the sheath abuts against the restricting surface 24S of the front wall portion 13 of the housing 20, restricting its upward movement. Also, as shown in Figure 4, the restricting wall 29 of the path restricting portion 27 restricts the lateral movement of the second wire 100. The sheath 25 is routed in the routing space 12 at an intermediate position in the front-to-back direction and slightly to the right in the left-to-right direction. If the sheath 25 covering the two second wires 100 is positioned excessively forward in the routing space 12, the routing length (untwisted length H) of the second wire 100 between the end face 25S of the sheath and the second cavity 31 becomes longer, degrading the transmission characteristics. In the connector 10 of this disclosure, in a plan view, the sheath 25 is positioned at an intermediate position in the front-to-back direction at the lower end of the routing space 12. This prevents the untwisting length H of the second wire 100 between the end face 25S of the sheath 25 and the rear end of the second cavity 31 from becoming too long, thereby suppressing deterioration of transmission characteristics.

[0053] As shown in Figures 3 and 4, the dielectric 30 housed in the module housing chamber 11 Cavity 1: 46 The rear end surface 46S and Second Cavity 31A gap D in the front-rear direction is left between the rear end surface 31S and the first wire 90. The lateral portion 52 and the lower portion 53 prevent the second wire 100 from extending further rearward than the first wire 90. This ensures a gap in the front-rear direction between the first wire 90, which bends and extends downward behind the first cavity 46, and the second wire 100, which bends and extends downward behind the second cavity 31. The transmission characteristics of the connector 10 are maintained well by separating the first wire 90 and the second wire 100 in the front-rear direction. In a side view, for example, the radius of curvature of the first bend 91 is Second bending part 101 This is larger than the radius of curvature. As a result, sufficient spacing in the front-to-back direction can be secured between the first wire 90 and the second wire 100 within the wiring space 12.

[0054] Next, the front sealing ring 110 is attached to the housing 20. The front sealing ring 110 seals the housing 20 in a liquid-tight manner against the mating portion of the mating connector (not shown).

[0055] Next, the front retainer 120 is attached to the housing 20 from the front. The front retainer 120 secondarily prevents the terminal fitting 55 from coming loose by restricting the bending movement of the plate-shaped portion 21.

[0056] Next, the bottom cover 70 is fitted to close the bottom opening 19 of the housing 20. Specifically, the bottom locking claws 72 on both sides of the bottom cover 70 are fitted to the lower locking receiving portion 15 of the housing 20. Also, the fitting of the bottom cover 70 causes the lip portion 81 of the rubber stopper 80 to adhere tightly to the inner wall of the housing 20, preventing liquid from entering from below. Insert the rubber stopper 80. Sheath 25 The end face 25S is in contact with the restricting surface 24S of the cable routing space 12, thereby restricting its vertical movement.

[0057] The inclined extensions 92 of the two first wires 90 leading out from the rear end of the first cavity 46 are curved diagonally forward while extending downward by the first bend 91, and extend toward the midpoint in the front-rear direction of the lower end of the wiring space 12. This prevents the wiring space 12 from becoming larger at the rear compared to when the first wires 90 are extended vertically downward by the first bend 91. The first wires 90, which are curved and extend diagonally forward, are again bent vertically downward by the first downward bend 93, from a position where they are spaced apart from the sheath 25 on the left and right. The first wires 90 and the sheath 25 are spaced apart on the left and right. A certain distance is maintained between the first wires 90 and the second wires 100 in the left-right direction. The connector 10 prevents deterioration of transmission characteristics due to the above-mentioned distance between the first wires 90 and the second wires 100 in the left-right direction.

[0058] Next, the rear cover 60, equipped with a rear sealing ring 115, is attached. The rear locking claws 62 of the rear cover 60 engage with the upper locking receiver 16 of the connector 10. The rear sealing ring 115, positioned outside the engagement point, completely seals the rear side of the housing 20, providing a waterproof function. The front end of the partition wall 63 abuts against the rear surface of the sheath 25, restricting the rearward movement of the sheath 25. With these steps, the assembly of the connector 10 is complete.

[0059] The connector 10 of Embodiment 1 comprises a housing 20 and a terminal module 30A. The housing 20 has a module housing chamber 11 and a wiring space 12 that communicates with the rear end of the module housing chamber 11. The terminal module 30A is inserted into the module housing chamber 11 from the rear. The terminal module 30A includes a first electric wire 90, a first terminal fitting 55A fixed to the first electric wire 90, a second electric wire 100, a second terminal fitting 55B fixed to the second electric wire 100, and a dielectric 30 housed in the module housing chamber 11. The dielectric 30 has a first cavity 46 in which the first terminal fitting 55A is housed, and a second cavity 31 located below the first cavity 46 in which the second terminal fitting 55B is housed. The first electric wire 90, which is led out into the routing space 12 from the rear end of the first cavity 46, has a first bend 91 in which the portion of the wire leading out is bent in a direction that intersects with the insertion direction of the dielectric 30 into the module housing chamber 11 within the routing space 12. The second electric wire 100, which is led out into the routing space 12 from the rear end of the second cavity 31, has a second bend 101 that is bent in the same direction as the first bend 91. The rear end of the first cavity 46 is located behind the rear end of the second cavity 31.

[0060] Since the rear end of the first cavity 46 is located behind the rear end of the second cavity 31, the first wire 90 having the first bend 91 and the second wire 100 having the second bend 101 can be easily routed with a gap between them in the front-to-back direction within the routing space 12. This suppresses the deterioration of transmission characteristics caused by the proximity of the first wire 90 and the second wire 100 within the housing 20.

[0061] In Embodiment 1, it is preferable that the second cavity 31 has a shorter length in the front-to-back direction than the first terminal fitting 55A.

[0062] With this configuration, when attempting to house the first terminal fitting 55A in the second cavity 31, a portion of the first terminal fitting 55A protrudes from the second cavity 31, thereby preventing the first terminal fitting 55A from being mistakenly housed in the second cavity 31.

[0063] The first electric wire 90 extends downward from the first bend 91 within the wiring space 12. The second electric wire 100 extends from the second bend 101 within the wiring space 12 in the same direction as the first bend 91. In the wiring space 12, it is preferable that the first electric wire 90 and the second electric wire 100 are wired with a gap between them in the left-right direction.

[0064] In this configuration, the first wire 90 and the second wire 100 are routed with a gap not only in the front-to-back direction but also in the left-to-right direction. Compared to the case where the first wire 90 and the second wire 100 are routed without a gap in the left-to-right direction, a larger gap can be secured between the first wire 90 and the second wire 100 within the routing space 12. Therefore, deterioration of transmission characteristics can be effectively suppressed without increasing the dimensions of the routing space 12 in the front-to-back direction.

[0065] The connector 10 further includes an elastic member 80 that closes the opening at the end of the wiring space 12 opposite to the module housing chamber 11. The elastic member 80 has a first seal hole 83 through which the first electric wire 90 passes, and a second seal hole 82 through which the second electric wire 100 passes. It is preferable that the first seal hole 83 and the second seal hole 82 are spaced apart in the left-right direction.

[0066] With this configuration, by inserting the first wire 90 and the second wire 100 into the first seal hole 83 and the second seal hole 82 of the elastic member 80, the first wire 90 and the second wire 100 are maintained in a positional relationship where they are separated to the left and right in the wiring space 12, thereby preventing deterioration of transmission characteristics caused by the first wire 90 and the second wire 100 being in close proximity.

[0067] [Embodiment 2] A connector 130 of Embodiment 2, which embodies the present disclosure, will be described with reference to Figure 6-12. In the description of Embodiment 2, the same configuration as in Embodiment 1 will be omitted from the description, as will the same effects and advantages as in Embodiment 1.

[0068] [Connector 130] As shown in Figure 7-9, the connector 130 of this embodiment 2 comprises a housing 150, a terminal module 30A, a rear cover 160 that closes the housing 150 from the rear, a left side cover 170 that closes the housing 150 from the left side, a rubber stopper 200, a front seal ring 215, a rear seal ring 210, and a front retainer 220. The housing 150 has an L-shape when viewed from above. Inside the housing 150, there is a module housing chamber 131 that extends in the front-rear direction, and a wiring space 132 that extends to the left from the rear of the module housing chamber 131. The outer surface of the housing 150 is covered by a front wall portion 135 and a side wall portion 133. A front opening 134 is formed on the front of the housing 150. A rear opening 138 is formed on the rear of the housing 150 over its entire area. A left side opening 139 is formed on the left side of the housing 150.

[0069] As shown in Figures 8 and 9, the cable routing space 132 is an internal space formed in the left-right direction at the rear of the housing 150. The first electric wire 180 and the front end region of the second electric wire 190, which will be described later, are housed in the cable routing space 132. The front wall portion 135 of the cable routing space 132 has an overhanging inclined surface 136 that is inclined so as to expand in the front-rear direction as the cable routing space 132 is moved to the left. The inclined surface 136 has a recessed stepped portion 137 formed by a restricting surface 137S perpendicular to the left-right direction and a wall surface 136S perpendicular to the front-rear direction. The stepped portion 137 is formed by vertically cutting out the inclined surface 136. The end face 140S of the sheath 140 of the second electric wire 190 is in contact with the restricting surface 137S of the stepped portion 137, which is perpendicular to the left-right direction. The stepped portion 137 is positioned at an intermediate position in the front-rear direction on the inner wall of the left end of the cable routing space 132 when viewed from the side of the housing 150. As shown in Figure 9, a route regulating portion 141 is formed on the lower right side of the cable routing space 132. The route regulating portion 141 consists of a guide inclined surface 142 that slopes forward as it moves to the left, and a pair of regulating walls 143 that extend rearward from the left and right side edges of the guide inclined surface 142.

[0070] The terminal module 30A of Embodiment 2 includes a first electric wire 180, a first terminal fitting 195A, a second electric wire 190, a second terminal fitting 195B, and a dielectric 30. The first electric wire 180 is fixed to the first crimp portion 196A of the first terminal fitting 195A and extends into the cable routing space 132. As shown in Figure 8, the first electric wire 180 has a first bend portion 181 that bends the first electric wire 180 to the left. As shown in Figure 7, the portion of the first electric wire 180 from the rear end of the first terminal fitting 195A to the first bend portion 181 extends, for example, along the front-to-back direction. As shown in Figure 8, the first electric wire 180 has an inclined extension portion 182. The inclined extension portion 182 is the portion that extends diagonally to the front left from the first bend portion 181 toward the midpoint of the front-to-back width in the expanded cable routing space 132A formed by the inner wall of the left end of the cable routing space 132. The first electric wire 180 has a first lateral bend portion 183. The first lateral bend portion 183 is connected to the lower end of the inclined extension portion 182. The portion of the first electric wire 180 below the first lateral bend 183 extends vertically to the left. The first electric wires 180 extend one by one from two first cavities 46 formed in the intermediate dielectric 45. In the wiring space 132, each first electric wire 180 is positioned above the second electric wire 190. The first bend 181 causes the first electric wire 180 to bend forward from the vertical left direction.

[0071] The second electric wire 190 is fixed to the second crimp portion 196B of the second terminal fitting 195B and extends into the wiring space 132. The second electric wire 190 has a second bend portion 191 that bends to the left in the same direction as the first electric wire 180. The portion of the second electric wire 190 from the rear end of the second terminal fitting 195B to the second bend portion 191 extends, for example, along the front-to-back direction. The second electric wire 190 is , theFrom the second bend 191, the wires extend almost vertically to the left when viewed from below. The second wires 190 extend one by one from two second cavities 31 formed in the lower dielectric 35. The two second wires 190 led into the wiring space 132 extend further to the left from the second bend 191 and are covered collectively on their outer circumference by an insulating sheath 140. In the wiring space 132, the two second wires 190 are positioned below the first wire 180. The first bend 181 bends the first wire 180 to the left at an acute angle with respect to the front-to-back direction. The first lateral bend 183 bends the first wire 180 to the left at an obtuse angle with respect to the left-to-right direction.

[0072] The housing 150 is equipped with a rear cover 160 that closes the rear. The rear cover 160 has a horizontally elongated rectangular rear plate portion 161, rear locking claws 162 extending forward from both the upper and lower sides of the rear plate portion 161, and a rectangular partition wall 163 extending forward in the center of the rear plate portion 161. The rear cover 160 engages with the housing 150 via the rear locking claws 162. When the rear cover 160 and the housing 150 are engaged, the rear plate portion 161 closes the rear of the housing 150. When the rear cover 160 and the housing 150 are engaged, the front end of the partition wall 163 is the front end of the sheath 140. Rear side It comes into contact with it.

[0073] The housing 150 includes a left side cover 170 that closes the left side of the housing 150. The left side cover 170 has a rectangular side plate portion 171 and from both the top and bottom sides of the side plate portion 171 right sideIt is equipped with a left side locking claw 172 that extends to the left. The left side locking claw 172 engages with the left locking receiving portion 144 of the housing 150, which will be described later. The left side cover 170 has a pair of connecting rods 173 that extend to the right from the side flat plate portion 171 and connect to a rubber stopper 200, which will be described later. A second guide hole 174 is formed on the lower side of the left side cover 170 when viewed from the side, through which a sheath 140 that covers the second electric wire 190 is inserted. A pair of first guide holes 175 are formed in the left side cover 170 at a position above the second guide hole 174, through which two first electric wires 180 are inserted.

[0074] A rubber stopper 200 is positioned on the right side of the left side cover 170. The rubber stopper 200 has a pair of connecting holes 204. The left side cover 170 is secured by inserting a pair of connecting rods 173 into the connecting holes 204. Rubber stopper 200 It is connected to the above. As shown in Figure 10, the rubber stopper 200 has a second seal hole 201 on its lower side, which passes through the sheath 140 covering the second electric wire 190 when viewed from the side. The rubber stopper 200 has a pair of first seal holes 202 above the second seal hole 201, which pass through the two first electric wires 180.

[0075] <Effects of Connector 130> The assembly of the connector 130 is carried out in the following procedure. The steps of inserting the first wire 180 and the second wire 190 into the sealing holes (201, 202), crimping the terminal fittings (195A, 195B) and the wires (180, 190), assembling the terminal module 30A, attaching the front sealing ring 215, attaching the front retainer 220, and attaching the rear cover 160 are the same as in Embodiment 1.

[0076] As shown in Figure 7, the assembled terminal module 30A is mounted to the housing 150. More specifically, the dielectric 30 of the terminal module 30A is inserted into the module housing chamber 131 from the rear of the housing 150. The dielectric 30 is housed in the module housing chamber 131 in a state where its movement is restricted, similar to Embodiment 1. As shown in Figure 8, when the dielectric 30 is housed in the module housing chamber 131, Cavity 1: 46 The rear end surface 46S and Second Cavity 31 A gap D in the front-rear direction is formed between the rear end faces 31S. As a result, a gap D in the front-rear direction is secured between the first wire 180, which bends from the rear of the first cavity 46 and extends to the left, and the second wire 190, which bends from the rear of the second cavity 31 and extends to the left, thereby suppressing deterioration of transmission characteristics.

[0077] The left side cover 170 is fitted, closing the left side opening 139 of the housing 150. Specifically, the left side locking claws 172 on both sides of the left side cover 170 are fitted to the left side locking receiving portion 144 of the housing. Furthermore, the fitting of the left side cover 170, Rubber stopper 200 The lip portion 205 is in close contact with the inner wall of the housing 150. left It prevents liquid from entering.

[0078] As shown in Figure 9, insert the rubber stopper 200. Sheath 140 The end face 140S is in contact with the restricting surface 137S of the wiring space 132, thereby restricting its movement to the right. If the sheath 140 covering the two second wires 190 is positioned excessively forward within the wiring space 132, the wiring length (untwisted length H) of the second wires 190 between the end face 140S of the sheath and the second cavity 31 becomes longer, degrading the transmission characteristics. In the connector 130 of this disclosure, the sheath 140 is positioned at an intermediate position in the front-rear direction at the left end of the wiring space 132 when the housing 150 is viewed from the side. As a result, Sheath 140 Since the length of the second electric wire 190 between the end face 140S and the rear end of the second cavity 31 does not increase (untwist length H), deterioration of transmission characteristics can be suppressed.

[0079] As shown in Figure 9, the two second wires 190 leading out from the rear end of the second cavity 31 are restricted to a position lower than the first wire 180 by the path restricting section 141 formed in the lower left part of the wiring space 132. Immediately after inserting the dielectric 30 into the module housing chamber 131, the second wires 190 protrude behind the rear end of the lateral portion 145 of the intermediate dielectric 45. However, by pulling the second wires 190 toward the path restricting section 141, the cover inclined surface 146 can easily guide the second wires 190, which protrude behind the rear end of the lateral portion 145 of the intermediate dielectric 45, to a position forward of the lateral portion 145 and behind the guide inclined surface 142. Thus, the position of the second wires 190 can be restricted between the guide inclined surface 142 and the lateral portion 145 in the front-rear direction. Furthermore, the side portion 145 forms an overhang that covers the second wire 190 from the rear, preventing the second wire 190 from protruding to the rear. As a result, the two first wires 180 that lead out from the rear end of the first cavity 46 are positioned forward and upward relative to the second wire 190.

[0080] As shown in Figure 8, the dielectric 30 housed in the module housing chamber 131 Cavity 1: 46 The rear end surface 46S and Second Cavity 31 A gap D in the front-rear direction is left between the rear end surface 31S and the connector. The lateral portion 145 and the lower portion 147 prevent the second wire 190 from extending further rearward than the first wire 180. This ensures a gap in the front-rear direction between the first wire 180, which bends behind the first cavity 46 and extends to the left, and the second wire 190, which bends behind the second cavity 31 and extends to the left. The transmission characteristics of the connector 130 are maintained well because the first wire 180 and the second wire 190 are separated in the front-rear direction. In a plan view, the radius of curvature of the first bend portion 181 is larger than the radius of curvature of the second bend portion 191. This ensures a sufficient gap in the front-rear direction between the first wire 180 and the second wire 190 within the wiring space 132.

[0081] As shown in Figure 8, the inclined extensions 182 of the two first electric wires 180 leading out from the rear end of the first cavity 46 are curved forward by the first bend 181 and extend to the left. The inclined extensions 182 extend from the first bend 181 toward an intermediate position in the front-rear width of the expanded wiring space 132A formed by the inner wall of the left end of the wiring space 132. This prevents the wiring space 132 from becoming larger to the rear compared to the case where the first electric wires 180 are extended vertically to the left by the first bend 181. The first electric wire 180, which is curved and extends diagonally forward, is bent by the first lateral bend 183 at a position where it is spaced vertically apart from the sheath 140. Furthermore, the first electric wire 180 extends from the first lateral bend 183 parallel to the sheath 140 and to the left, perpendicular to the front-to-back direction. The first electric wire 180 and the sheath 140 are spaced apart vertically. A certain vertical gap is maintained between the first electric wire 180 and the second electric wire 190. The connector 130 prevents deterioration of transmission characteristics due to the vertical gap between the first electric wire 180 and the second electric wire 190.

[0082] Next, similar to Embodiment 1, the rear cover 160, which is equipped with a rear sealing ring 210, is attached, and the assembly of the connector 130 is completed.

[0083] The connector 130 of Embodiment 2 comprises a housing 150 and a terminal module 30A. The housing 150 has a module housing chamber 131 and a wiring space 132 that communicates with the rear end of the module housing chamber 131. The terminal module 30A is inserted into the module housing chamber 131 from the rear. The terminal module 30A has a first electric wire 180, a first terminal fitting 195A fixed to the first electric wire 180, a second electric wire 190, a second terminal fitting 195B fixed to the second electric wire 1190, and a dielectric 30 housed in the module housing chamber 131. The dielectric 30 has a first cavity 46 in which the first terminal fitting 195A is housed, and a second cavity 31 located below the first cavity 46 in which the second terminal fitting 195B is housed. The first electric wire 180, which is led out into the wiring space 132 from the rear end of the first cavity 46, has a first bent portion 181 in which the portion leading to the leading end in the direction of lead generation is bent in a direction that intersects with the direction in which the dielectric 30 is inserted into the module housing chamber 131 within the wiring space 132. The second electric wire 190, which is led out into the wiring space 132 from the rear end of the second cavity 31, has a second bent portion 191 that is bent in the same direction as the first bent portion 181. The rear end of the first cavity 46 is located behind the rear end of the second cavity 31.

[0084] In the connector 130 of Embodiment 2, it is preferable that the second cavity 31 has a shorter length in the front-to-back direction than the first terminal fitting 195A.

[0085] In the connector 130 of Embodiment 2, the first wire 180 extends laterally from the first bend 181 within the routing space 132. The second wire 190 extends from the second bend 191 within the routing space 132 in the same direction as the first bend 181. In the routing space 132, it is preferable that the first wire 180 and the second wire 190 are routed with a gap between them in the vertical direction.

[0086] In this configuration, the first wire 180 and the second wire 190 are routed with a gap not only in the front-to-back direction but also in the up-and-down direction. Compared to the case where the first wire 180 and the second wire 190 are not spaced apart in the up-and-down direction, a larger gap can be secured between the first wire 180 and the second wire 190 within the routing space 132. Therefore, deterioration of transmission characteristics can be effectively suppressed without increasing the dimensions of the routing space 132 in the front-to-back direction.

[0087] The connector 130 of Embodiment 2 may further include an elastic member 200 that closes the opening at the end of the wiring space 132 opposite to the module housing chamber 131. The elastic member 200 has a first seal hole 202 through which the first electric wire 180 passes and a second seal hole 201 through which the second electric wire 190 passes. Preferably, the first seal hole 202 and the second seal hole 201 are spaced apart in the vertical direction.

[0088] According to this configuration, the first wire 180 and the second wire 190 Elastic member 200 By inserting the first wire 180 and the second wire 190 through the first seal hole 202 and the second seal hole 201, the first wire 180 and the second wire 190 are maintained in a positional relationship that is separated vertically in the wiring space 132, thereby preventing deterioration of transmission characteristics caused by the proximity of the first wire 180 and the second wire 190. [Other embodiments] (1) In Embodiments 1 and 2, the second electric wire (100, 190) led out from the rear end of the second cavity 31 has a second bent portion (101, 191) that is bent in the same direction as the first bent portion (91, 181). The same direction means that the direction of the second electric wire extending from the second bent portion to the opposite side of the second terminal fitting and the direction of the first electric wire extending from the first bent portion to the opposite side of the first terminal fitting are the same in the up, down, left, and right directions. The radius of curvature of the first bent portion and the second bent portion do not need to be exactly the same. (2) In the housing 150 of Embodiment 2, the cable routing space 132 may be configured to extend from the rear to the right of the module housing chamber 131. (3) In Embodiments 1 and 2, the housings 20 and 150 communicate with the module housing chamber and the cable routing space in an L-shape, but for example, the cable routing space may be connected to the module housing chamber in a way that it bends diagonally. (4) In Embodiments 1 and 2, the dielectric 30 is formed by a lower dielectric 35, a middle dielectric 45, and a dielectric cover 65, but the dielectric 30 may consist of only a single component. (5) In Embodiments 1 and 2, the terminal module 30A houses a total of four terminal fittings, but the number of terminal fittings housed in the terminal module may be three or fewer, or five or more. (6) The connectors (10, 130) of Embodiment 1 and Embodiment 2 are equipped with rubber stoppers (80, 200) as elastic members. The elastic member used in the connector is not limited to rubber stoppers, and for example, synthetic resin may be used. [Explanation of symbols]
