As a result, the connector 100 with a double shield structure of this embodiment has a structure that can be manufactured more inexpensively than the connector 950 of Patent Document 2, while improving the shielding characteristics more than the connector 900 of Patent Document 1. That is, the connector 100 with a double shield structure of this embodiment improves the shielding characteristics while suppressing the manufacturing cost.

[0059] 6 and 10, the size S1 in the horizontal direction of the shielding portion 540 is larger than the size S2 in the horizontal direction of the opening 470. Note that the present invention is not limited thereto, and the size S1 in the horizontal direction of the shielding portion 540 may be the same as the size S2 in the horizontal direction of the opening 470. However, when the size S1 in the horizontal direction of the shielding portion 540 is matched to the size S2 in the horizontal direction of the opening 470, the shielding portion 540 needs to be processed so that the size S1 of the shielding portion 540 matches the size S2 of the opening 470. In addition, the above processing does not lead to an improvement in the electrical performance of the connector 100. Furthermore, even if the above processing is performed, the area of ​​the metal plate required for manufacturing the connector 100 does not change, and does not lead to a reduction in the manufacturing cost of the connector 100. Therefore, the shielding portion 540 of this embodiment is more preferable.

[0060] As shown in FIG. 16, the shielding portion 540 includes two shielding plate portions 542.

[0061] As shown in FIG. 18, each of the shielding plates 542 of this embodiment has a flat plate shape perpendicular to the front-rear direction.

[0067] As shown in Fig. 16, each of the side edges 565 in this embodiment extends in the vertical direction. The side edges 565 define both outer ends of the receiving hole 562 in the lateral direction. The side edges 565 correspond to the outer side plate portions 520, respectively. Each of the side edges 565 is located on the inner side of the corresponding outer side plate portion 520 in the lateral direction. With reference to Figs. 8 and 16, the side edges 565 correspond to the inner side plate portions 420 of the inner shell 400, respectively. Each of the side edges 565 is located on the outer side of the corresponding inner side plate portion 420 in the lateral direction.

[0068] 18, each of the contact pieces 568 of the present embodiment is provided on a periphery 563 of the accommodating hole 562. Each of the contact pieces 568 extends forward in the front-rear direction from the periphery 563 of the accommodating hole 562. Each of the contact pieces 568 has a contact portion 5682.

[0069] As shown in FIG. 18, the contact portion 5682 of the present embodiment is located near the front end of the contact piece 568 in the front-rear direction.

The horizontal portion 610 defines the front end of the contact 600 in the front-rear direction. The horizontal portion 610 has a front end 612 and a rear end 614 in the front-rear direction. As shown in FIG. 3, the cylindrical portion 450 surrounds the horizontal portion 610 of the contact 600. The first portion 210 corresponds to the horizontal portion 610 of the contact 600. A part of the horizontal portion 610 is exposed in the mating contact portion receiving portion 216.

[0076] As shown in FIG. 23, the horizontal portion 610 has a plate-shaped contact portion 616 and a held portion 618 .

[0077] 3, the contact portion 616 in this embodiment is a portion that comes into contact with a mating contact portion (not shown) of a mating contact (not shown) of a mating connector when the connector 100 is mated with the mating connector. The contact portion 616 faces upward in the vertical direction. The contact portion 616 is located in front of the held portion 618 in the front-rear direction. The contact portion 616 is located in front of the upper surface 212 of the first portion 210 in the front-rear direction. The contact portion 616 is located in front of the holding portion 218 of the first portion 210 in the front-rear direction. The contact portion 616 is exposed in the mating contact portion receiving portion 216. The contact portion 616 is located in front of the second portion 220 in the front-rear direction. The contact portion 616 is located in front of the shielding portion 540 in the front-rear direction. The contact portion 616 is located behind the front end 502 of the outer shell 500 in the front-rear direction.

[0078] 3, the held portion 618 in this embodiment is held by the holding portion 218 of the first part 210 of the inner housing 200. More specifically, the held portion 618 is press-fitted into the holding portion 218.

[0079] As shown in FIG. 23, the vertical portion 620 of this embodiment extends in the vertical direction. The vertical portion 620 extends downward in a vertical direction perpendicular to the front-rear direction from the rear end 614 of the horizontal portion 610. The vertical portion 620 defines the rear end of the contact 600 in the front-rear direction. As shown in FIG. 3, the vertical portion 620 is located near the rear end of the inner housing 200 in the front-rear direction. The vertical portion 620 is located near the rear end of the first portion 210 in the front-rear direction. The vertical portion 620 is located near the rear end of the second portion 220 in the front-rear direction. The second portion 220 corresponds to the vertical portion 620 of the contact 600. The vertical portion 620 is located rearward of the third portion 230 in the front-rear direction. The inner back plate portion 460 is located rearward of the vertical portion 620 of the contact 600 in the front-rear direction. The outer back plate portion 560 is located behind the vertical portion 620 in the front-rear direction.

[0080] As shown in FIG. 23, the contact 600 further includes an SMT portion 630 .

[0081] 3, the SMT section 630 of the present embodiment is fixed to an object 700 when the connector 100 is used. The SMT section 630 extends rearward in the front-to-rear direction from the lower end in the vertical direction of the vertical section 620. The SMT section 630 defines the lower end of the contact 600 in the vertical direction.

[0082] In conventional connectors, the positioning of the SMT part of the contact is performed by mounting the external shell or the external housing on the object 700 when the connector is fixed to the object. However, in such conventional connectors, the assembly tolerance between the external shell or the external housing and the internal shell or the internal housing, and the assembly tolerance of the contact to the internal housing affect the position of the SMT part, making it difficult to control the position of the SMT part. On the other hand, in the connector 100 of the present embodiment, as described above, when the connector 100 is fixed to the object 700, the third part 230 of the internal housing 200 that holds the contact 600 is mounted on the object 700. As a result, in the connector 100 of the present embodiment, it is easier to control the position of the SMT part 630 relative to the object 700 when the connector 100 is fixed to the object 700, compared to the conventional connector.

[0083] As shown in FIG. 4, the connector 100 further includes an outer housing 300 .

[0084] With reference to Fig. 4, the external housing 300 of this embodiment is made of an insulating material. As shown in Fig. 3, the external housing 300 protrudes forward in the front-rear direction beyond the front end 502 of the external shell 500. The external housing 300 is located outside the cylindrical portion 450 in a direction perpendicular to the front-rear direction. With reference to Fig. 1, when the connector 100 is attached to the housing 850, a part of the external housing 300 protrudes outside the housing 850 through an opening 852 provided in the housing 850. A part of the external housing 300 constitutes a fitting portion that fits with a mating fitting portion (not shown) of the mating connector when the connector 100 is fitted to the mating connector.

[0085] 2, the outer housing 300 is provided with two mis-mating prevention keys 310. These mis-mating prevention keys 310 are provided to prevent the mating connector from being reversely inserted into the connector 100. That is, if the mating connector is to be mated with the connector 100 in the wrong orientation, the mis-mating prevention keys 310 of the connector 100 interfere with a part of the mating connector, preventing the connector 100 from mating with the mating connector, whereas if the mating connector is to be mated with the connector 100 in the correct orientation, the mis-mating prevention keys 310 of the connector 100 do not interfere with the mating connector, allowing the connector 100 to be completely mated with the mating connector.

[0086] Although the present invention has been specifically described above by way of the embodiment, the present invention is not limited thereto and various modifications are possible. In addition, a plurality of the above-described embodiments and modifications may be combined.

[0087] Although the inner housing 200 of the present embodiment has the first portion 210, the second portion 220, and the third portion 230, the present invention is not limited thereto, and may be configured with only the first portion 210. In this case, the vertical portion 620 of the contact 600 faces the shielding portion 540 of the outer shell 500 in the front-rear direction. However, since impedance matching is easily achieved when an insulator is located near the vertical portion 620 of the contact 600, it is preferable that the inner housing 200 has the first portion 210 and the second portion 220.

[0088] In the connector 100 of this embodiment, the end faces 4322 of the two plate-like portions 432 face each other in the lateral direction, but the present invention is not limited to this. For example, one of the two plate-like portions 432 may be provided with a recess recessed outward in the lateral direction, and the other of the two plate-like portions 432 may be provided with a protrusion protruding inward in the lateral direction, and the protrusion of one plate-like portion 432 may be fitted into the recess of the other plate-like portion 432, thereby joining the two plate-like portions 432 to each other in the lateral direction.

[0089] Although the contact 600 of the connector 100 in this embodiment has the plate-shaped contact portion 616, the present invention is not limited to this. That is, the contact portion 616 may be a spring contact.

[0090] In the connector 100 of this embodiment, the held portion 618 provided on the horizontal portion 610 of the contact 600 is press-fitted into the holding portion 218 provided on the first portion 210 of the inner housing 200, but the present invention is not limited to this. That is, the connector 100 may be modified so that the held portion 618 provided on the vertical portion 620 of the contact 600 is press-fitted into the holding portion 218 provided on the second portion 220 of the inner housing 200.
