In a state where the fitting portion 41 is fitted with the counterpart blocking unit 114, that is, in a connector fitted state, the blocking unit 40 forms an electromagnetic shield together with the counterpart blocking unit 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 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 attachment portions 44 is shown in Figs. 10 and 11, It is good if they are placed at the same position in the Y direction. Moreover, it is more preferable if the respective thicknesses (length in the Y direction) of the fitting portion 41 and the attachment portion 44 are substantially uniform. In other words, in the Y direction, the cross section of the fitting portion 41 and the cross section of the attachment portion 44 may be on the same plane. In this case, the blocking portion 40 can be compactized, and the space for arranging the blocking portion 40 within the frame 11 can be further reduced.

In the connector 10 of the present invention, 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 made of the same member and are integrated. In detail, the side wall 12 and the bottom wall 17 of the frame 11 are composed of the same member, specifically, one metal plate M, and a part of the same metal plate M is used to form a blocking portion ( 40) has been formed. The material of the metal plate M is not particularly limited, but examples include copper alloys such as brass and bronze, or stainless steel. Additionally, 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 of the connector 10 of the present invention can be manufactured by applying drawing processing (strictly square barrel drawing processing) to the metal plate M as shown in FIG. 14, for example. Specifically, while holding the outer edge of the metal plate M with a die or the like, a pressing mechanism P, such as a punch, is pressed against a portion of the metal plate M located inside the outer edge. As a result, as shown in FIG. 14, a rectangular cylindrical metal molded product (hereinafter referred to as frame base material F) having a drawn bottom portion is obtained. The drawing bottom portion is located at the innermost portion (bottom portion) among the portions formed by pushing the metal plate M during drawing processing.

An opening is formed in the frame base material F on the surface side (hereinafter referred to as the upper surface side) against which the pressing mechanism P is pressed, and this opening becomes the opening 10A at the time of completion of the frame 11. Additionally, the rectangular portion of the frame base material F becomes the side wall 12 at the time of completion of the frame 11. In addition, the outer edge portion of the metal plate M disposed during the drawing process remains as a collar-shaped edge portion on the upper surface side of the frame base material F, and is a flange portion at the time of completion of the frame 11. It becomes (53).

After performing the drawing process, the bottom portion of the frame base material F is punched into a predetermined shape. As a result, of the frame base material F, the drawn bottom portion includes a portion corresponding to the bottom wall 17 (specifically, the edge portion 18 and the corner portion 19) of the frame 11 and the blocking portion 40. A significant portion remains. At this stage, the portion corresponding to the bottom wall 17 (more specifically, the portion corresponding to the corner portion 19) and the portion corresponding to the blocking portion 40 are continuously connected.

Thereafter, the bottom of the drawing 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 part corresponding to the blocking portion 40 of the bottom of the drawing is bent at approximately 90 degrees with respect to the part corresponding to the bottom wall 17 and made to stand.

Through the above procedures, 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. This ensures the strength and barrier properties (shielding properties) of the frame 11.

Moreover, in each part of the side wall 12, the rising part 51 and the flange part 53 are seamlessly connected. 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 a guide portion 54. In this way, in the process of manufacturing the frame 11 by performing drawing processing on one metal plate M, the guide portion 54 can be formed incidentally.

In addition, the side wall 12 and the bottom wall 17 of the frame 11 are seamlessly connected, and the blocking portion 40 is seamlessly connected to the bottom wall 17. In particular, the blocking portion 40 is formed by bending the metal plate M at the boundary between the bottom wall 17 and the blocking portion 40. By this, compared to a conventional connector (for example, the connector 1 described in Patent Document 1), which requires separate provision of the frame 11 and the blocking portion 40, the number of connector components can be reduced. You can.

To explain in more detail, when the frame 3 of the connector 1 described in Patent Document 1 is manufactured by drawing processing, the surface on which the pressing mechanism P is pressed during processing (in other words, the flange portion is formed side) is fixed to a substrate not shown. Meanwhile, the bottom of the drawing formed by pressing the pressing mechanism P is punched, and the punched hole becomes the opening 2 for fitting the mating connector into the inside of the frame 3. When providing the blocking portion 5 inside the frame 3 manufactured by this procedure, the parts constituting the blocking portion 5 are prepared separately from the frame 3, and the parts are added to the frame 3. It is assembled at the lower end (end of the substrate side).

On the other hand, although the frame 11 provided in the connector 10 of the present invention is manufactured by drawing processing, the surface on which the pressing mechanism P is pressed during processing is the upper surface (+Z side surface). Do it as That is, the drawn bottom formed by firmly pressing the pressing mechanism P corresponds to the lower end of the frame 11. In this configuration, the blocking portion 40 can be formed using a portion of the drawing bottom. Therefore, there is no need to make the blocking portion 40 a separate part, and the number of parts is reduced. Additionally, the connector manufacturing cost can be lowered by reducing the number of parts.

In addition, when the frame 3 provided in the connector 1 described in Patent Document 1 is manufactured by drawing processing, as described above, the drawing bottom is punched, etc. to create an opening 2 for inserting the mating connector. forms. At this time, it is necessary to punch a relatively large hole according to the dimensions of the counterpart 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 mechanism P during drawing processing is an opening 10A for inserting the counterpart connector 100. ), and is used as is. That is, according to the present invention, there is no need to significantly punch the bottom of the drawing to secure the opening 10A, and the frame 11 having the opening 10A of the required size can be easily manufactured through drawing processing.

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