As a result, the connector 200 can be configured with two parts, the insulator 60 and the shell 100, and the number of parts can be reduced compared to the conventional example.

  (2) Since the lock mechanism 107 for the substrate-side connector 400 is formed on the metal shell 100, sufficient strength can be obtained, and the connector can be miniaturized.

  (3) The wiring member 50 is held off by the wiring member holding portion 114 provided in the shell 100, and one end of the wiring member 50 where the conductor pattern 51 is exposed is the wiring member holding portion 114 and the front plate of the insulator 60 It becomes a state where it is sandwiched between the step portion 71 at the lower end in the Z direction of the portion 62 and is positioned well.

  (4) Since the tip (edge 53) of the wiring member 50 is protected by the step portion 71, the tip of the wiring member 50 is not damaged when the connector 200 is fitted to the substrate-side connector 400.

  (5) A structure in which the wiring material wrapping prevention part 103 is provided in the shell 100, and a force generated when the wiring material 50 is scraped is received by the latch part 104 fixed to the insulator 60 at both ends of the wiring material wrapping prevention part 103 Because of this, it is possible to prevent the wiring member 50 from being separated from the insulator 60 due to bending.

  (6) In the wiring material 50, a shield material is disposed in a direction opposite to the edge 53 from the ground plate 54, and there is a mode in which only both sides or one side is covered by the shield material. Although the thickness is increased, since the wiring material wrap prevention portion 103 is positioned at a position one step higher than the upper plate portion 102, the wiring material 50 can be mounted without any problem even if the wiring material 50 becomes thick. In this example, the thickness of the wiring member 50 can be permitted below the broken line a shown in FIG.

  Although the ground plate 54 is separated from the reinforcing plate 52 in the wiring member 50 as shown in FIG. 6C, the ground plate 54 may be partially overlapped with the reinforcing plate 52. In this case, a fold is formed in the area of the ground plate 54, and the wiring material 50 is bent by 90 degrees together with the ground plate 54.

  Hereinafter, a second embodiment of the connector according to the present invention shown in FIGS. 11 to 16 will be described.

  11 and 12 show a state in which the wiring material is attached to the connector as in FIGS. 1 and 2. FIGS. 13 to 15 show details of insulator 60 'and shell 100' in connector 500 shown in FIG. Is shown. Further, FIG. 16 shows a state in which the connector 500 is fitted and connected to the board-side connector 400, as in FIG. The same reference numerals are given to parts corresponding to the configuration of the first embodiment, and the detailed description will be omitted.

  In the first embodiment, the shell 100 is provided with a mechanism for preventing the wiring member 50 from turning around, but in the second embodiment, the insulator 60 'has a mechanism for preventing the wiring member 50 from turning around. It has become.

  The insulator 60 'is configured as shown in FIGS. The difference from the insulator 60 shown in FIGS. 3 and 4 is that the pair of arm portions 63 does not have the holes 86 in which the latched portions 87 are provided inside, and the wiring material anti-overlay bar 92 straddles the pair of arm portions 63. It is at a point that is stretched in the Y direction.

  The wiring material wrapping prevention bar 92 is located behind the block portion 61, and the lower surface of the wiring material wrapping prevention bar 92 is located at a position higher than the height of the top surface of the block part 61 in the Z direction.

  On the other hand, the shell 100 'is configured as shown in FIG. The difference from the shell 100 shown in FIG. 5 is that the wiring material wrap prevention portion 103 and the latch portions 104 formed at both ends thereof are not provided.

  In a connector 500 including such an insulator 60 'and a shell 100', the wiring member 50 is mounted under the wiring material wrap preventing bar 92 and mounted on the insulator 60 'as shown in FIGS. The wiring material bending prevention bar 92 is located on the opposite side of the wiring material 50 from the side where the third surface 72 of the insulator 60 ′ is located. Thereby, even if the wiring member 50 is twisted, the displacement in the direction away from the third surface 72 is prevented by the wiring member winding preventing bar 92.

  Also in the connector 500 of the second embodiment, the same effect as that of the connector 200 of the first embodiment described above can be obtained. Although it can be said that the connector 500 of the second embodiment is superior in terms of the strength against bending of the wiring member 50, the height of the connector 500 in the Z direction is equivalent to the presence of the wiring member preventing bar 92. Since the height is increased, the configuration of the connector 200 of the first embodiment is preferable in terms of reducing the height.
