  As shown in FIGS. 9B and 10B, the plug contact terminal 111 is a metal terminal connected to the multicore cable 121 and connected to a socket contact terminal 642 of a connector socket 640 described later. . As shown in FIGS. 3 and 4, the plug contact terminal 111 includes a contact portion 111 a that comes into contact with a socket contact terminal 642, which will be described later, and a conductor portion connection portion 111 b that is connected to a signal line 121 b of a multicore cable 121, which will be described later. The bending portion 111c that connects the contact portion 111a and the conducting wire portion connecting portion 111b in a curved shape is provided. The contact portion 111a has a shape in which the end portion on the front end side is bent at about 45 degrees toward the inner side where the insulator 112 is located and then extends straight toward the rear end. Is inserted into the groove. The conducting wire part connecting part 111b is a wide part formed at the end part on the rear end side, and has a shape in which a circular hole is provided in the center of the wide part. Solder-bonded to the conductor portion 121c, which is the portion where the coating at the tip of the wire 121b has been removed (see FIG. 10B). The curved portion 111c is formed to be curved in an S shape between the contact portion 111a and the conductor portion connecting portion 111b. The number of plug contact terminals 111 is four in this embodiment, but is not limited to this. Further, in this embodiment, the plug contact terminal 111 uses, for example, a copper thin plate material plated with gold, but is not limited thereto.

  As shown in FIG. 3, the insulator 112 holds a plurality of plug contact terminals 111 at equal intervals, and is inserted into a connector socket 640 (see FIG. 6), which will be described later, so that the displacement of the relative position can be adjusted. It is a member. Thereby, the plug contact terminal 111 and the socket contact terminal 642 described later are electrically contacted. The insulator 112 is fixed to fix the lead wire connecting portion 111b of the plug contact terminal 111 so that the movable insulator 112a held by the contact portion 111a of the plug contact terminal 111 and the curved portion 111c of the plug contact terminal 111 can move. And an insulator 112b. The insulator 112 is formed of, for example, a resin material, and the movable insulator 112a and the fixed insulator 112b are simultaneously formed by insert molding so that the plug contact terminal 111 is attached.

  In the movable insulator 112a, an insertion portion 112c for fixing the plug contact terminals 111 in parallel at equal intervals is formed on the top surface on the tip side. The movable insulator 112a is movable with respect to the fixed insulator 112b in the direction in which the plug contact terminals 111 are arranged and in a direction perpendicular to the arrangement direction. Further, the bending portion 111c follows in accordance with the movement of the movable insulator 112a. The insertion portion 112 c has a shape that is narrowed so as to be fitted to the connector socket 640. Further, as shown in FIG. 3, both of the long sides of the end portion on the rear end side of the movable insulator 112a are fitted into guide holes 113b provided on the upper and lower sides of the front end side of the mold cover 113 (see FIG. 2). The pull-out restricting portion 112d is provided at the top and bottom. The pull-out restricting portion 112d contacts the inside of the guide portion 113a and restricts the amount of movement of the movable insulator 112a in the distal direction. In addition, on both the short sides of the end portion on the rear end side of the movable insulator 112a, push-in restricting portions 112e are provided on the left and right sides. The push-in restricting portion 112e contacts the front end surface of the side wall 112f of the fixed insulator 112b, and restricts the amount of movement in the rear end direction of the movable insulator 112a.

  The fixed insulator 112b is provided with a side wall 112f for fitting with the inner peripheral portion of the mold cover 113, facing the left and right with a predetermined interval. A slit portion 112g that holds the contact portion 111a and the curved portion 111c of the plug contact terminal 111 parallel to each other at equal intervals and is movable up and down is formed in a portion sandwiched between the side walls 112f.

The pair of guide portions 113a are provided facing each other so as to protrude inwardly above and below the end portion on the front end side of the mold cover 113. The positioning portion 113c is an opening formed in a portion protruding outward from the rear end side of the upper portion of the mold cover 113.

  The mold cover 113 movably holds the movable insulator 112a by the guide portion 113a, the guide hole 113b, and the left and right inner peripheral surfaces of the tip of the mold cover 113. The movable insulator 112a is slightly movable with respect to the fixed insulator 112b and the mold cover 113 so as to be tiltable in the vertical and horizontal directions in the connector insertion direction. Further, the movable insulator 112a is moved to cause the plug contact terminal 111 to bend, but the curved portion 111c of the plug contact terminal 111 is bent inside the fixed insulator 112b to absorb the bend of the plug contact terminal 111. it can.

When the front shell 114 is assembled to the insulator 112 and the mold cover 113, first, the insulator 112 integrated with the plug contact terminal 111 is inserted into the mold cover 113, and then the conductor portion connection of the plug contact terminal 111 is performed. After the lead wire portion 121c, which is the portion where the coating of the signal wire 121b of the multi-core cable 121 is peeled off, is soldered and fixed to the portion 111b, they cover the upper and lower left and right sides of the mold cover 113 and are fixed. The insulator 112b is fixed by being inserted into the front shell 114 so as to cover the conductor wire connecting portion 111b of the plug contact terminal 111 and the signal wire 121b of the multi-core cable 121 from the rear end wall 112h of the insulator 112b.

  As shown in FIG. 2, the rear shell 115 is formed, for example, into a substantially gate shape by sheet metal processing of a metal material so that the lateral width gradually decreases toward the rear. The rear shell 115 covers the conductive wire connecting portion 111b of the plug contact terminal 111 and the upper part of the signal line 121b of the multi-core cable 121 from the rear of the front shell 114, and suppresses the emission and intrusion of electric noise of the signal line 121b. This is a shield member. As shown in FIG. 1, the rear shell 115 includes a positioning claw portion 115a that engages with the positioning portion 113c of the mold cover 113, a pair of attachment claw portions 115b that engage with the attachment portion hole 114b of the front shell 114, and the like. In addition, a locking piece 115c that is crimped simultaneously with the shield wire 121a of the multi-core cable 121 by a locking piece of the shell crimping portion 114c of the front shell 114 is provided. The positioning claw portion 115a is bent downward at the upper end portion toward the positioning portion 113c provided on the rear end side of the mold cover 113. In the pair of attachment claws 115b, the left and right side walls of the rear shell 115 are each punched inward, and are bent obliquely upward. The lock piece 115c extends in a substantially rectangular shape from the upper surface of the rear shell 115 to the rear. The rear shell 115 is positioned by crimping the lock piece 115c to the shield wire 121a of the multi-core cable 121 by the shell crimping portion 114c, and at the same time can be grounded.
