More specifically, a concave portion (hereinafter, fitting concave portion 116 ) formed at a position corresponding to the fitting portion 41 is provided in the X-direction central portion of the opposing blocking portion 114 . The fitting concave portion 116 has a depth sufficient to accommodate the distal ends (ie, the contact convex portions 47 ) on both sides of the pair of protruding pieces 43 . In addition, the width (length in the X direction) of the fitting recesses 116 is slightly narrower than the distance between the protruding pieces 43 , more precisely, the gap at the time before each protruding piece 43 is elastically deformed.

When fitting the connector, as shown in FIG. 13 , the pair of protruding pieces 43 of the fitting portion 41 are elastically deformed to narrow the gap between the protruding pieces 43 , and the inner side of the fitting concave portion 116 . go to the side Thereby, the fitting portion 41 is fitted with the fitting concave portion 116 . In a state in which the fitting portion 41 has entered the inner portion of the fitting concave portion 116 , the tip of each of the pair of protruding pieces 43 , that is, the contact convex portion 47 , is on the inner surface of the fitting concave portion 116 . contact Moreover, it is preferable if the recessed part formed corresponding to the curved shape of the contact convex part 47 so that the inner surface of the fitting recessed part 116 may fit with the contact convex part 47 is provided.

In a state in which the fitting portion 41 is fitted with the opposing blocking unit 114 , that is, in a connector fitting state, the blocking unit 40 together with the opposing blocking unit 114 constitutes an electronic shield. As described above, this electromagnetic shield suppresses signal crosstalk between the two contacts 31 and 32 for high-frequency signal transmission.

In each of the blocking portion 40 on the +Y side and the blocking portion 40 on the -Y side, each of the fitting portion 41 and the two attaching portions 44 is as shown in Figs. What is necessary is just to arrange|position at the same position in a Y direction. Moreover, it is more preferable if each thickness (length in Y direction) of the fitting part 41 and the attachment part 44 is substantially uniform. In other words, in the Y direction, the end face of the fitting portion 41 and the end face of the attachment portion 44 may be on the same plane. In this case, the blocking part 40 can be made compact, and the arrangement space of the blocking part 40 in the frame 11 can be made smaller.

In addition, for the purpose of reducing the number of parts, the side wall 12, the bottom wall 17, and the blocking portion 40 of the frame 11 are constituted by the same member and are integrated. In detail, the side wall 12 and the bottom wall 17 of the frame 11 are constituted by the same member, specifically, one metal plate M, and a blocking part using a part of the same metal plate M is used. (40) is formed. Although the material of the metal plate M is not specifically limited, For example, copper alloys, such as brass and bronze, or stainless steel, etc. are mentioned. Moreover, although the plate|board thickness of the metal plate M is not specifically limited, For example, it is set to 0.06 mm - 0.15 mm.

The frame 11 of the connector 10 of the present invention can be manufactured by, for example, applying a drawing process (strictly, a square cylinder drawing process) to the metal plate M as shown in FIG. 14 . Specifically, a pressing mechanism P such as a punch is pressed against a portion of the metal plate M located inside the outer edge portion of the metal plate M while holding the outer edge portion of the metal plate M with a dice or the like. Thereby, as shown in FIG. 14, the rectangular-shaped metal molded article (henceforth frame base material F) which has a drawing bottom part is obtained. The drawing bottom is a portion located at the innermost portion (bottom) of the portions formed by pushing the metal plate M during drawing processing.

An opening is formed in the surface side (henceforth upper surface side) to which the pressing mechanism P was pressed among the frame base materials F, and this opening becomes 10 A of openings at the time of completion|finish of the frame 11. As shown in FIG. Moreover, the square cylinder part in the frame base material F becomes the side wall 12 at the time of completion of the frame 11. As shown in FIG. Moreover, among the metal plate M, the outer edge part arrange|positioned during implementation of a drawing process remains as a collar-shaped edge part on the upper surface side of the frame base material F, and at the time of completion of the frame 11, a flange part. (53).

After implementation of the drawing process, the bottom part of the frame base material F is punched out in a predetermined shape. Thereby, in the frame base material F, a portion corresponding to the bottom wall 17 (specifically, the edge portion 18 and the corner portion 19) of the frame 11 at the bottom of the drawing, and the blocking portion 40 A significant portion remains. In this step, the part corresponding to the bottom wall 17 (in detail, the part corresponding to the leg part 19) and the part corresponding to the blocking part 40 are connected continuously.

Thereafter, the drawing bottom is bent at the boundary between the portion corresponding to the bottom wall 17 and the portion corresponding to the blocking portion 40 . More specifically, among the drawing bottoms, the portion corresponding to the blocking portion 40 is bent by approximately 90 degrees with respect to the portion corresponding to the bottom wall 17 to stand up.

The frame 11 is manufactured from one metal plate M through the above procedure. In the frame 11 manufactured by the above procedure, the side walls 12 are seamlessly continuous over the entire circumference of the frame 11 . Thereby, the strength and barrier property (shielding property) of the frame 11 are ensured.

Moreover, in each part of the side wall 12, the rising part 51 and the flange part 53 are connected seamlessly. A bent portion 52 is provided between the raised portion 51 and the flange portion 53 , and the bent portion 52 and the flange portion 53 constitute the guide portion 54 . In the process of manufacturing the frame 11 by performing the drawing process on one metal plate M as described above, the guide portion 54 may be formed incidentally.

As described above, in the connector 10 of the present invention, the guide portion 54 is formed of the same member as the side wall 12 (specifically, the same metal plate M), and is integrated with the side wall 12 . Thereby, compared with the case where the side wall 12 and the guide part 54 are comprised by the other member, the number of parts is further reduced, and the manufacturing cost of the connector 10 can be reduced. In particular, according to the above-described procedure, the guide portion 54 is formed by bending the upper end of the side wall 12 toward the outside of the frame 11 . Thereby, the guide part 54 can be formed more easily using a part of the member which comprises the side wall 12. As shown in FIG.

In addition, in the connector 10 of the present invention, the guide portion 54 is provided over the entire circumference of the frame 11 . Thereby, compared with the conventional connector (for example, the connector 1 described in patent document 1) which has a part corresponding to the guide part 54, the mating-side connector 100 is more suitable for the frame 11. I can guide you inside.

More specifically, the frame 3 provided in the connector 1 described in Patent Document 1 is a rectangular frame, and as shown in Figs. (5) is provided. The bent portion 5 is configured by bending the upper end of the frame 3 toward the inside of the frame 3 . By providing the bent portion 5 , the mating connector 2 is properly guided inside the frame 3 when the connector is fitted, as shown in FIG. 19 .

However, in the upper end of the frame 3, the bent portion 5 is provided only at each portion, and the portion where the bent portion 5 does not exist is a concave portion. Therefore, there is a possibility that the mating connector 2 is caught in the recess in the frame 3 when the connector is engaged. If the mating connector 2 in the state of being caught in the recess is pushed in strongly, there is a fear that the connector 1 or the mating connector 2 may be deformed or damaged.

On the other hand, in the connector 10 of the present invention, the guide portion 54 is provided over the entire circumference of the frame 11 at the upper end of the frame 11, and the concave portion does not exist. Accordingly, the mating connector 100 is not caught in the recessed portion during connector fitting, and deformation and damage of the connector 10 or the mating connector 100 resulting therefrom can be avoided.

Moreover, each part (each part in the circumferential direction of the frame 11) of the guide part 54 provided over the whole perimeter of the frame 11 exists in the same position in the Z direction. Thereby, the mating connector 100 becomes more difficult to catch on the frame 11 during connector fitting, and the mating connector 100 can be more appropriately guided to the inside of the frame 11 .
