It is preferable that the inner side surface of the fitting recess 116 is provided with a recess formed so as to fit the contact convex portion 47 so as to correspond to the curved shape of the contact convex portion 47.

In the state where the fitting portion 41 is fitted with the mating side blocking portion 114, that is, in the connector fitting state, the blocking portion 40 constitutes an electromagnetic shield together with the mating side blocking portion 114. 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 + Y side cutoff portion 40 and the −Y side cutoff portion 40, the fitting portion 41 and each of the two mounting portions 44 are arranged at the same position in the Y direction as shown in FIGS. 10 and 11. It is good to have. Further, it is more preferable that the thicknesses (lengths in the Y direction) of the fitting portion 41 and the mounting portion 44 are substantially uniform. In other words, it is preferable that the end surface of the fitting portion 41 and the end surface of the mounting portion 44 are on the same plane in the Y direction. In this case, the blocking unit 40 can be made compact, and the space for arranging the blocking unit 40 in the frame 11 can be made smaller.

In the connector 10 of the present invention, the side wall 12, the bottom wall 17, and the blocking portion 40 of the frame 11 are made of the same member and integrated for the purpose of reducing the number of parts. More specifically, the side wall 12 and the bottom wall 17 of the frame 11 are made of the same member, specifically, one metal plate M, and the blocking portion 40 is made by using a part of the same metal plate M. Is formed. The material of the metal plate M is not particularly limited, and examples thereof include copper alloys such as brass and bronze, stainless steel, and the like. The thickness of the metal plate M is not particularly limited, but is set to, for example, 0.06 mm to 0.15 mm.

The frame 11 included in the connector 10 of the present invention can be manufactured, for example, by applying drawing processing (strictly speaking, square cylinder drawing processing) to the metal plate M as shown in FIG. Specifically, while holding the outer edge portion of the metal plate M by sandwiching it with a die or the like, the pressing device P such as a punch is pressed against the portion of the metal plate M located inside the outer edge portion. As a result, as shown in FIG. 14, a square tube-shaped metal molded product having a throttle bottom (hereinafter, frame base material F) can be obtained. The drawing bottom portion is a portion located at the innermost portion (bottom portion) of the portions formed by pushing the metal plate M during drawing processing.

Of the frame base material F, an opening is formed on the surface side (hereinafter, the upper surface side) against which the pressing device P is pressed, and this opening becomes the opening 10A when the frame 11 is completed. Further, the square tube portion in the frame base material F becomes the side wall 12 when the frame 11 is completed. Further, of the metal plate M, the outer edge portion sandwiched during the drawing process remains as a flange-shaped edge portion on the upper surface side of the frame base material F, and becomes the flange portion 53 at the time of completion of the frame 11.

After the drawing process is performed, the bottom portion of the frame base material F is punched into a predetermined shape. As a result, 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 and a portion corresponding to the blocking portion 40 remain at the bottom of the diaphragm. At this stage, the portion corresponding to the bottom wall 17 (specifically, the portion corresponding to the corner portion 19) and the portion corresponding to the blocking portion 40 are continuously connected.

After that, the bottom portion of the diaphragm 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, the portion of the bottom of the diaphragm corresponding to the blocking portion 40 is bent approximately 90 degrees with respect to the portion corresponding to the bottom wall 17 to stand upright.

Through the above procedure, the frame 11 is manufactured from one metal plate M. In the frame 11 manufactured by the above procedure, the side wall 12 is seamlessly continuous over the entire circumference of the frame 11. As a result, the strength and blocking property (shielding property) of the frame 11 are ensured.

Further, in each portion of the side wall 12, the rising portion 51 and the flange portion 53 are seamlessly connected. A bent portion 52 is provided between the rising portion 51 and the flange portion 53, and the bent portion 52 and the flange portion 53 form a guide portion 54. In the process of manufacturing the frame 11 by drawing the single metal plate M in this way, the guide portion 54 can be incidentally formed.

Further, the side wall 12 of the frame 11 and the bottom wall 17 are seamlessly connected, and the blocking portion 40 is seamlessly connected to the bottom wall 17. In particular, the cutoff portion 40 is formed by bending the metal plate M at the boundary portion between the bottom wall 17 and the cutoff portion 40 in the metal plate M. As a result, the number of connector components can be reduced as compared with the conventional connector (for example, the connector 1 described in Patent Document 1) in which the frame 11 and the cutoff portion 40 need to be provided separately.

More specifically, when the frame 3 of the connector 1 described in Patent Document 1 is manufactured by drawing, the surface against which the pressing tool P is pressed during processing (in other words, the surface on the side where the flange portion is formed) is It is fixed to a substrate (not shown). On the other hand, the bottom of the diaphragm formed by pressing the pressing device P is punched out, and the punched hole becomes an opening 2 for fitting the mating connector inside the frame 3. When the cutoff portion 5 is provided inside the frame 3 manufactured by such a procedure, the parts constituting the cutoff portion 5 are prepared separately from the frame 3, and the parts are prepared at the lower end portion of the frame 3 (the end portion on the substrate side). ) Will be assembled.

On the other hand, although the frame 11 provided in the connector 10 of the present invention is manufactured by drawing, the surface on which the pressing device P is pressed during processing is the upper surface (the surface on the + Z side). That is, the bottom portion of the diaphragm formed by pressing the pressing device P corresponds to the lower end portion of the frame 11. In such a configuration, the cutoff portion 40 can be formed by utilizing a part of the bottom portion of the diaphragm. Therefore, it is not necessary to use the blocking unit 40 as a separate component, and the number of components is reduced. In addition, the connector manufacturing cost can be reduced by reducing the number of parts.

Further, when the frame 3 provided in the connector 1 described in Patent Document 1 is manufactured by drawing, as described above, an opening 2 for fitting the mating connector is provided by punching the bottom of the drawing or the like. Form. At this time, it is necessary to punch a hole having a relatively large size according to the dimensions of the mating connector.

On the other hand, in the frame 11 provided in the connector 10 of the present invention, as described above, the opening formed by pressing the pressing device P during drawing processing is the opening 10A for fitting the mating connector 100. As it is used as it is. That is, according to the present invention, it is not necessary to punch out the bottom of the drawing in order to secure the opening 10A, and the frame 11 having the opening 10A of a required size can be easily manufactured by drawing.

As described above, in the present invention, the frame 11 seamlessly integrated with the blocking portion 40 can be easily manufactured by performing drawing processing and bending processing on one metal plate M. Thereby, it is possible to provide a connector having a lower manufacturing cost.
