In the present embodiment, since the first pressure contact portion 114 and the second pressure contact portion 124 extend in a direction oblique to the X direction, the size (height) of the housing 130 in the Z direction can be suppressed. The bending of the electric wire 210 press-contacted to the first press contact portion 114 and the second press contact portion 124 can also be reduced. Furthermore, since both the first pressure contact portion 114 and the second pressure contact portion 124 according to the present embodiment extend in a plane oblique to the Y direction, the size (width) of the housing 130 in the Y direction can be suppressed. ing. In other words, according to the present embodiment, the size can be reduced in the Z direction and the Y direction. In particular, in the present embodiment, as shown in FIG. 5, the four first press contact portions 114 and the four second press contact portions 124 are formed in the Y direction (lateral direction) and Z direction (vertical direction) of the housing 130. ) Are arranged so as to be symmetric with respect to the midpoint.

That is, each holding hole 164 extends in the X direction. There are eight holding holes 164 according to the present embodiment, four on the + Z side (upper side) and four on the −Z side (lower side), and the pair of holding holes 164 positioned above and below communicate with each other. Is integrated. However, the present invention is not limited to this, and all the holding holes 164 may be independent from each other.

  In the present embodiment, the pair of twisted electric wires 210 included in the cable 200 is inserted into the holding holes 164 positioned in the vertical direction (that is, the pair of holding holes 164).

  As understood from FIGS. 10 and 20, a light press-fit portion 166 having a small diameter is formed at the + X side end portion (front end) of the holding hole 164. Therefore, when the electric wire 210 is inserted into the holding hole 164 (lightly press-fitted), the electric wire 210 is held at the light press-fitting portion 166. As described above, since the holding of the electric wire 210 with respect to the holding member 160 according to the present embodiment is performed by light press fitting, it is possible to avoid a situation in which the electric wire 210 is deformed during holding by the holding member 160 and to hold the holding point.

The angle of the front slope 172 according to the present embodiment is the same as the angle of the rear slope 136 of the housing 130. That is, the front slope 172 and the rear slope 136 extend in parallel.

  The abutting part 174 is a part that abuts against the abutted part 138. When the abutting part 174 is abutted against the abutted part 138, the front slope 172 and the rear slope 136 are located apart in the X direction by a distance corresponding to the projection amount of the abutting part 174. Thereby, the accommodating part 12 in which the attachment member 180 is accommodated is formed between the housing 130 and the holding member 160 (see FIGS. 1 and 17). When the abutting portion 174 is abutted against the abutted portion 138, the relative position of the holding member 160 with respect to the housing 130 (that is, the relative position between the sheath 230 of the cable 200 and the housing 130) can be roughly determined. it can.

  A marker 176 protruding in the + X direction (forward) is formed in the middle of each front slope 172 in the Z direction.

  As described above, since the four first press contact portions 114 and the four second press contact portions 124 are arranged so as to be point-symmetric, according to the present embodiment, as best shown in FIG. The attachment members 180 have the same shape. Therefore, the cost can be reduced as compared with a configuration in which different mounting members are required on the upper and lower sides.

  As shown in FIG. 11, each mounting member 180 has an inner surface 182 that will be located inside when assembled to the housing 130 and an outer surface 184 that will be located outside. Each attachment member 180 is formed with a holding slit 190 that penetrates from the inner surface 182 to the outer surface 184 and an attachment hole 186 that intersects and communicates with the holding slit 190. The attachment hole 186 in the present embodiment extends in a direction parallel to the inner surface 182 and the outer surface 184, and the holding slit 190 extends in a direction orthogonal to the inner surface 182 and the outer surface 184. Specifically, the mounting hole 186 extends in the XZ plane, whereas the holding slit 190 extends in a direction oblique to any of the X direction, the Y direction, and the Z direction. Although not perpendicular to the mounting hole 186, as can be confirmed in FIG. 17, the direction in which the holding slit 190 extends (that is, the oblique direction) and the direction in which the mounting hole 186 extends when viewed along the Y direction. They are orthogonal to each other. In other words, the mounting hole 186 extends in a direction orthogonal to the oblique direction in a plane including the X direction and the oblique direction (in the XZ plane in the present embodiment).

  There are four mounting holes 186 according to the present embodiment, and communicate with each other in the Y direction. However, the present invention is not limited to this, and the mounting holes 186 may be independent of each other. A light press-fit portion 188 having a small diameter is provided in the vicinity of the front end of each mounting hole 186. When the electric wire 210 is inserted into the mounting hole 186 (light press fitting), the light press fitting portion 188 holds the electric wire 210. That is, the attachment member 180 is attached to the electric wire 210. That is, the attachment of the attachment member 180 to the electric wire 210 is performed only by lightly press-fitting the electric wire 210 into the attachment hole 186, so that the electric wire 210 can be prevented from being damaged. Note that the light press-fit portion 188 in the present embodiment is located on the front side (+ X side) of the holding slit 190.

  Both ends of the mounting member 180 in the Y direction protrude outward in the Y direction, and in the oblique direction (in the upper mounting member 180, the rear obliquely upward direction (−X direction and + Z direction), and in the lower mounting member 180, the rear A guided portion 192 made of a ridge extending obliquely downward (−X direction and −Z direction) is provided. The size in the Y direction of the portion (main portion) excluding the guided portion 192 of the mounting member 180 is substantially equal to the distance between the two side wall portions 134 of the housing 130. In other words, the mounting member 180 has a main portion 181 having a size in the Y direction equal to the distance between the two side wall portions 134 of the housing 130, and the guided portion 192 is further outward from the main portion 181 in the Y direction. It protrudes.

  Furthermore, each guided portion 192 according to the present embodiment protrudes from the inner surface 182. The guided portion 192 is a portion that is guided by the guide portion including the first guide portion 142 to the third guide portion 146 of the housing 130.

Alignment with 190 is also made. In other words, the guided portion 192 and the guide portion (the first guide portion 142 to the third guide portion 146) are not only slid in the oblique direction of the mounting member 180, but also the first press contact portion 114 or the second press contact portion. The size, position, and the like are determined and provided in consideration of the alignment between 124 and the holding slit 190. Accordingly, when the mounting member 180 is slid, the first press contact portion 114 or the second press contact portion 124 is held by the holding slit even if the first press contact portion 114 or the second press contact portion 124 cannot be visually recognized in the holding slit 190. It is possible to avoid a situation in which the first press contact portion 114 or the second press contact portion 124 is deformed due to the failure to be received in 190.

  Furthermore, as described above, the tips of the first pressure contact portion 114 and the second pressure contact portion 124 according to the present embodiment are tapered, so that they are easily received in the holding slit 190. In order to more easily receive the first pressure contact portion 114 or the second pressure contact portion 124 in the holding slit 190, a guide (tapered surface) may be formed on the inner surface 182 side of the holding slit 190.

  As predicted from FIG. 17, the guided portion 192 and the holding slit 190 in the present embodiment overlap when viewed through the mounting member 180 along the Y direction. In other words, the guided portion 192 is provided on the side of the holding slit 190.

  Further, as shown in FIGS. 2 and 11, an auxiliary guided portion 194 is provided at the rear end (−X direction end portion) of the attachment member 180 in the present embodiment. The auxiliary guided portion 194 extends in the oblique direction similarly to the guided portion 192, and has an L-shaped cross section in a direction orthogonal to the oblique direction. A part of the auxiliary guided portion 194 is guided to a space formed between the front inclined surface 172 and the rear inclined surface 136 when the abutting portion 174 is abutted against the abutted portion 138, and the auxiliary guided portion 194 The other part slides on the inner surface of the side wall 170 of the holding member 160. In other words, the auxiliary guided portion 194 moves so as to extend over the corner portion on the front inner side of the side wall portion 170 of the holding member 160. Thereby, the guide of the guided part 192 by the guide part (the first guide part 142 to the third guide part 146) is held.

  The connection of the cable 200 to the connector 10 having such a structure will be described below.

  First, the sheath 230 of the cable 200 is peeled off, the shielding member 220 is folded back on the sheath 230, and the twists of the four pairs of electric wires 210 are returned to the holding holes 164 of the holding member 160 so that the electric wires 210 of each pair are positioned vertically. Lightly press-fitting and further lightly press-fit the upper four electric wires 210 into the mounting holes 186 of the upper mounting member 180, while lightly inserting the lower four electric wires 210 into the mounting holes 186 of the lower mounting member 180. Press fit. At this time, as shown in FIG. 12, the attachment member 180 is positioned at the position of the final attachment member 180, that is, the position closest to the abutting portion 174 on the front slope 172. More specifically, the corresponding four electric wires 210 are attached while pressing the attachment member 180 on the front slope 172 in a state where the attachment member 180 is positioned closest to the abutting portion 174 on the front slope 172. Lightly press fit into the hole 186. By pressing the attachment member 180 to a predetermined position on the front slope 172, there is no work variation with respect to the holding position of the electric wire 210 by the attachment member 180. That is, it is possible to prevent the problem that the signal transmission path length differs for each electric wire 210. Further, by setting the position on the front slope 172 to press the mounting member 180 as the final position of the mounting member 180 (position closest to the abutting portion 174 on the front slope 172), the mounting member 180 is actually mounted on the housing 130. When assembled, the situation that the length of the electric wire 210 becomes insufficient and the core wire 212 cannot be connected to the first press contact portion 114 or the second press contact portion 124 can be avoided.

  As shown in FIG. 12, after attaching the attachment member 180 onto the covering portion 214 of the electric wire 210, the electric wire 210 is cut into the state shown in FIG.

  Next, as shown in FIG. 14, the attachment member 180 is moved along the front slope 172 in the Z direction outside and in the −X direction. At this time, it is moved so as to exceed the marker 176. Accordingly, when the abutting portion 174 is abutted against the abutted portion 138, the mounting member 180 does not interfere with the abutting, and the guide portion (the first guide portion 142 to the third guide portion 146) is smoothly provided. It is possible to move to the guide of the guided portion 192. That is, whether the marker 176 has moved to a position where the guide member 192 can be guided by the guide portion (the first guide portion 142 to the third guide portion 146) of the attachment member 180 attached to the electric wire 210. It is a guideline.

  Next, as shown in FIG. 2, the abutting portion 174 is abutted against the abutted portion 138. In the present embodiment, since the first guide portion 142 protrudes in the Z direction, it is visually confirmed whether or not the guided portion 192 is in contact with the first guide portion 142 (whether or not it is in a state where it can be guided). be able to.

  Next, the mounting member 180 is assembled to the housing 130 by pushing the mounting member 180 obliquely downward (upward) forward. The actual assembly is performed by pressing the outer surface 184 of the mounting member 180 with a jig while pressing the front end of the housing 130 (the front end of the contact holding portion 132) so as not to move.

  Here, in a state in which the attachment member 180 is attached to the housing 130, the end surface 216 of the electric wire 210 is protected by the protection portion 150 of the housing 130 as shown in FIGS. 19 and 20. By the structure of the protection part 150, the short circuit between the adjacent electric wires resulting from dust etc. can be prevented.

  In the present embodiment, when the attachment member 180 is attached to the housing 130, the guided portion 192 is a guide portion (first guide portion 142 to third guide portion 146, as can be understood from FIGS. 15 and 16). 17 to 19, the second pressure contact portion 124 (the same applies to the first pressure contact portion 114) is smoothly received in the holding slit 190, and is pressed against the core wire 212 there. The Therefore, the first pressure contact portion 114 or the second pressure contact portion 124 can be connected to the core wire 212 without deforming the first pressure contact portion 114 or the second pressure contact portion 124, and the first pressure contact portion 114 of the electric wire 210 can be connected. In addition, since the connection position with the second pressure contact portion 124 is substantially constant, problems such as variations in the transmission path length due to work do not occur.

  While the present invention has been described in detail with reference to the embodiment, the present invention is not limited to this. For example, in the above-described embodiment, the first main portion 112 of the first contact 110 and the second main portion 122 (that is, the first contact portion 116 and the second contact portion 126) of the second contact 120 are shown in FIG. Are arranged in a line in the Y direction as described above, but may be arranged in two lines (see the arrangement of the pressure contact parts in FIG. 5), or in a zigzag pattern when viewed in the X direction. May be arranged.
