As shown in FIG. 1, the angle end bell 15 includes a surrounding portion 151 and a cable lead-out portion 152. The surrounding part 151 and the cable lead-out part 152 are integrally formed of resin. The surrounding part 151 is cylindrical and covers the rear end part of the shield part 131. Three lock claws (end bell side locking portions) 151 a are formed on the outer peripheral surface of the surrounding portion 151 at equal intervals in the circumferential direction. Eight alignment convex portions (end bell rotation direction position determining means) 151b are formed at equal intervals on the front end surface of the surrounding portion 151. An alignment recess (end bell rotation direction position determining means) 151c is configured by the adjacent alignment protrusions 151b. Further, a step surface 151 d is formed inside the front end portion of the surrounding portion 151.

  The cable lead-out portion 152 has a substantially cylindrical shape, is coupled to the surrounding portion 151 at a substantially right angle, and covers the clamp portion 132 of the shield member 13. Three lock claws 152 a are formed on the outer peripheral surface of the cable lead-out portion 152 at equal intervals in the circumferential direction.

The cylindrical portion 161 covers the tip end portion of the shield portion 131 of the shield member 13. Three misfitting prevention key grooves (misfitting prevention portions) 161a are formed on the outer peripheral surface of the cylindrical portion 161 at equal intervals in the circumferential direction. The erroneous fitting prevention key groove 161a extends along the fitting / removing direction. A step surface 161b is formed on the inner surface of the rear end portion of the cylindrical portion 161 (see FIG. 3). The step surface 161 b engages with the engagement piece 131 c of the shield member 13.

The flange portion 162 is coupled to the rear end of the cylindrical portion 161. Eight alignment recesses (end bell rotation direction position determining means) 162 a are formed at equal intervals on the outer peripheral surface of the flange portion 162. Eight alignment convex portions ( endbell rotation direction position determining means) 162b are configured by the adjacent alignment concave portions 162a. The alignment concave portion 162a is fitted into the alignment convex portion 151b of the angle end bell 15, and the alignment convex portion 162b is fitted into the alignment concave portion 151c of the angle end bell 15. When the alignment concave portion 162a is fitted into the alignment convex portion 151b of the angle end bell 15 and the alignment convex portion 162b is fitted into the alignment concave portion 151c of the angle end bell 15, the relative position of the surrounding portion 151 of the angle end bell 15 relative to the barrel 16 is increased. A position in the rotation direction ( a position around the central axis of the surrounding portion 151 of the angle end bell 15) is determined. At this time, since the positional relationship between the erroneous fitting prevention key 161a of the barrel 16 and the male terminal 11 of the connector main body 100 is not changed, the erroneous fitting prevention key groove 161a in the circumferential direction of the barrel 16 and the plug side housing 12 are held. The positional relationship with the male terminal 11 is kept constant. The direction of the cable lead-out portion 152 of the angle end bell 15 (position around the central axis of the enclosure 151 of the angle end bell 15) changes according to rotational position of the angle end bell 15. As described above, the end bell rotation direction position determining means is configured by the alignment convex portion 151b, the alignment concave portion 151c, the alignment concave portion 162a, and the alignment convex portion 162b.

  The flange portion 162 is formed by fitting the alignment concave portion 162a and the alignment convex portion 162b to the alignment convex portion 151b and the alignment concave portion 151c, respectively, and the angle end bell 15 through the O-ring (first seal member) 21. It is abutted against the step surface 151d. Thereby, the internal space of the angle end bell 15 and the barrel 16 is sealed (see FIG. 3). At this time, the surrounding portion 151 of the angle end bell 15 and the barrel 16 are coaxial.

  As shown in FIGS. 1 and 8, the coupling nut 18 has a cover portion 181 and a fitting portion 182. The cover part 181 and the fitting part 182 are integrally formed of resin. The cover portion 181 is substantially cylindrical and covers the surrounding portion 151 and the barrel 161 of the angle end bell 15. Three lock holes (first coupling nut side locking portions) 181a are formed in the rear end portion of the cover portion 181 at equal intervals in the circumferential direction. Further, a notch 181d is formed on the lower surface of the rear end portion of the cover portion 181. The notch 181d is for preventing the coupling nut 18 from contacting the angle end bell 15. Further, the rear end portion of the cover portion 181 can be expanded or contracted in the radial direction by the notch 181d. Therefore, when the coupling nut 18 is attached to the angle end bell 15 along the fitting / removing direction, the rear end portion of the cover portion 181 gets over the lock claw 151a, and the lock claw 151a of the angle end bell 151 is inserted into the lock hole 181a. Is done. As a result, the coupling nut 18 is locked to the angle end bell 15.

  A pair of lock pieces (second coupling nut side locking portions) 181b are formed at the front end portion of the cover portion 181. The pair of lock pieces 181b are in point-symmetrical positions with respect to the center of the cover portion 181. The lock piece 181b can be deformed in the radial direction of the cover portion 181 and has a hole 181c. The hole 181c receives a lock claw 54c of the receptacle connector 50 described later. At this time, the lock piece 181b and the lock claw 54c are engaged. A plurality of alignment key grooves 181e are formed at equal intervals in the circumferential direction on the inner peripheral surface of the front end portion of the cover portion 181. The keyway 181e receives the lock claw 54c of the receptacle connector 50 (see FIGS. 1 and 11).

  The fitting portion 182 is coupled to the cover portion 181 at a substantially right angle. A fitting recess (coupling nut side fitting portion) 182a is formed on the back surface of the fitting portion 182 (see FIG. 8). The fitting concave portion 182a receives the fitting convex portion 152b of the angle end bell 15.

  After fitting the fitting concave portion 182a and the fitting convex portion 152b, the ground nut 19 is inserted into the fitting portion 182 and the cable lead-out portion 152, and the three components of the coupling nut 18, the angle end bell 15 and the ground nut 19 are assembled. By locking the engagement, these fixations are strengthened, and the strength in the rotation direction with respect to the fitting shaft can be increased.

  The ground nut 19 has a bottomed cylindrical shape, and has a first housing portion 191 and a second housing portion 192. The first housing portion 191 and the second housing portion 192 are made of resin and are integrally formed. The cross-sectional shape of the first accommodating portion 191 is substantially circular, and three lock holes 191a are formed at the upper end portion thereof. The three lock holes 191 a are formed at equal intervals along the circumferential direction of the housing portion 191. The lock hole 191 a receives the lock claw 152 a of the angle end bell 15. Since the upper end portion of the first accommodating portion 191 can expand or contract in the radial direction, the three lock holes 191a engage with the lock pawl 152a in the radial direction of the first accommodating portion 191.

  The cross-sectional shape of the second accommodating portion 192 is substantially rectangular, and a lock hole 192a is formed at the upper end portion. The lock hole 192 a receives the lock claw 182 b of the coupling nut 18. Since the upper end portion of the second housing portion 192 can bend in the thickness direction, the lock hole 192a can be engaged with the lock claw 182b.

As a result, the lock claw 151a is not easily detached from the lock claw 151a, and the coupling nut 18 is firmly locked to the angle end bell 15. At this time, the fitting convex portion 152b of the angle end bell 15 is fitted into the fitting concave portion 182a (see FIG. 8) of the coupling nut 18. When coupling nut 18 is locked to the angle end bell 15, by the flange 1 62 is pressed by the convex portion 18a of the coupling nut 18 (see FIG. 3), the barrel 16 is the coupling nut 18 and angle endbell 15.

  Thereafter, the bushing (second shield member) 22 and the gland nut 19 are attached to the cable 28, and then the bushing 22 is moved upward as shown by the arrow in FIG. 9, and the angle end bell 15 is moved as shown in FIG. Is inserted into the cable lead-out portion 152. At this time, the bushing 22 is compressed. Thereafter, the ground nut 19 is attached to the cable lead-out portion 152 of the angle end bell 15 and the fitting portion 182 of the coupling nut 18. At this time, the upper end portion of the gland nut 19 spreads in the radial direction, so that the upper end portion of the gland nut 19 gets over the lock claw 152a of the angle end bell 15 and the lock claw 182b of the coupling nut 18, respectively, and lock holes 191a and 192a. The lock claws 152a and 182b are respectively inserted into the upper end of the gland nut 19, and the diameter of the upper end of the ground nut 19 is restored. As a result, the lock claws 152a and 182b are not easily detached from the lock holes 191a and 192a, respectively, and the ground nut 19 is firmly locked to the angle end bell 15 and the coupling nut 18.

  16 is a perspective view showing a state before the angle-type plug connector shown in FIG. 15 is connected to the receptacle connector shown in FIG. 11, and FIG. 17 is a diagram showing the angle-type plug connector shown in FIG. 15 connected to the receptacle connector shown in FIG. It is a perspective view which shows a back state. 16 and 17, the illustration of the cable is omitted for convenience.

  This connection work is the same as the connection work described with reference to FIGS. 13 and 14. First, as shown in FIG. 16, the positioning key 121a of the angle type plug connector 10 is inserted into the positioning key groove 52c of the receptacle connector 50, and the angle type. The erroneous fitting prevention key groove 161 a of the plug connector 10 is faced to the fitting main key 54 d of the receptacle connector 50, and the angle type plug connector 10 is pushed into the receptacle connector 50. Thereby, as shown in FIG. 17, the angle-type connector 10 is locked to the receptacle connector 50.

  According to the angle type plug connector of this embodiment, the cable drawing direction can be arbitrarily set at a predetermined angle by rearranging the components. In this embodiment, the alignment keyway 122a, the alignment recess 162a, and the alignment protrusion 151b are each 8 pieces, but the number may be reduced, and if it is increased, the cable is drawn out. The direction can be set to more positions.

  Since the outer parts (the angle end bell 15, the barrel 16, the coupling nut 18, etc.) other than the shield member 13 are made of resin, low cost, size reduction, and weight reduction can be achieved.

  Since the locking of the coupling nut 18 to the angle end bell 15 and the locking of the ground nut 19 to the angle end bell 15 can be performed by a linear pushing operation, the assembly work of the angle type plug connector 10 can be performed easily and reliably. .

  Further, this angle type plug connector has waterproofness and shielding properties.

  In this embodiment, the waterproof property and the shield property are provided. However, the waterproof property and the shield property may not be provided.
