Description

Technical Field

[0001] The present invention relates to a connector, and more particularly to a connector capable of being mated with a mating connector in a first direction and having a housing for holding contacts surrounded by a frame. Background Art

[0002] An example of a connector that mates with a mating connector is a connector (hereinafter referred to as connector 1) described in Patent Document 1. Connector 1 is a receptacle connector that mates with a mating connector (not shown) that is a plug connector in the vertical direction.

[0003] like Fig. 20 As shown, the connector 1 is composed of a housing 3 (insulating member) that holds contacts 2 (connection terminals) and is surrounded by a substantially rectangular frame 4 (fixed terminals). The frame 4 is fixed to a substrate (not shown) and is disposed at a position facing the side wall surface of the housing 3.

[0004] In addition, if Fig.21 As shown, protrusions 5 and 6 are provided at the lower part of the frame 4. When the frame 4 is viewed from above, the protrusions 5 and 6 are bent toward the side (i.e., the inner side) where the housing 3 is located. And, the housing 3 is held by the protrusions 5 and 6 of the frame 4 by inserting the distal ends of the protrusions 5 and 6 into the prescribed positions of the housing 3.

[0008] like Fig.21 As shown, in the frame 4, cutouts, more specifically, punching holes 7 are formed at both sides of the protrusions 5 and 6. The punching holes 7 are provided for the purpose of providing the protrusions 5 and 6, that is, holes provided for the purpose of cutting and bending the metal plate constituting the frame 4 to form the protrusions 5 and 6. By providing the punching holes 7, it becomes easier to form the protrusions 5 and 6 on the frame 4, that is, to perform the cutting and bending process. On the other hand, since the through holes are provided in the frame 4, the performance of the frame 4 such as the shielding property and the strength of the frame 4 may be reduced. Summary of the invention

[0009] The present invention has been made in view of the above circumstances, and an object thereof is to solve the following problems. The present invention aims to solve the above problems of the prior art and to provide a connector having a bent portion provided on a frame while ensuring frame performance.

[0010] In order to achieve the above-mentioned purpose, the connector of the present invention can be mated with the connector of the other side in the first direction, and the connector is characterized in that it comprises: a shell, on which contacts are installed; and a frame, whose end in the first direction is fixed to the substrate and surrounds the shell; at the end of the frame on the substrate side in the first direction, there is provided: a bending portion, which is bent in a second direction intersecting the first direction; and a pair of adjacent surfaces, which are adjacent to the two end surfaces of the bending portion in a third direction intersecting the first direction and the second direction respectively.

[0011] According to the connector of the present invention configured as described above, a bent portion is provided at the end of the frame on the substrate side in the first direction, and both end surfaces of the bent portion are adjacent to the surfaces (adjacent surfaces) located on both sides of the bent portion. That is, since there are no cutouts such as punching holes at both sides of the bent portion, it is possible to suppress the degradation of frame performance and the like caused by the formation of the cutouts.

[0012] In addition, in the connector of the present invention, the frame may be an electromagnetic shielding frame set to a ground potential. In this case, the effect of the present invention is more significant. That is, since there are no cutouts on both sides of the bent portion in the frame, the electromagnetic shielding of the frame is improved. As a result, the operation of the circuit including the connector is stable.

[0013] In addition, in the connector of the present invention, the end of the frame on the substrate side in the first direction can be fixed to the substrate by solder provided along the periphery of the frame and all over the periphery. In this case, since solder is provided all over the periphery of the frame, a small gap near the bent portion of the frame can be filled with solder. As a result, the electromagnetic shielding property of the frame is further improved.

[0014] Furthermore, in the connector of the present invention, the bending portion may be bent in the second direction toward the side where the shell is located, and a shell holding portion for holding the shell is connected to the end of the bending portion on the side where the shell is located in the second direction. In this case, the bending portion is required to integrate the shell holding portion with the frame, and the present invention in which the bending portion is provided on the frame without providing a cutout is more effective.

[0015] Furthermore, in the connector of the present invention, the contacts may include contacts for high-frequency signal transmission. In this case, since the frame serves as an electromagnetic shield in the high-frequency band, the effect of improving the electromagnetic shielding property of the frame is more significant.

[0016] In addition, in the present invention, the frame can be divided into two fragments of the same shape, and the two fragments respectively have a pair of walls extending in the second direction and a connecting wall extending in the third direction and connecting the pair of walls. The two fragments are arranged in a state opposite to each other to surround the shell.

[0017] In addition, in the present invention, a plurality of bent portions and a pair of adjacent surfaces having the same number as the bent portions may be provided at the end portion on the substrate side in the first direction in the frame. In this case, preferably, in the third direction, both end surfaces of the plurality of bent portions are adjacent to the corresponding pair of adjacent surfaces. Thus, even when a plurality of bent portions are provided on the frame, a decrease in the performance of the frame can be suppressed.

[0018] Furthermore, in the present invention, the pair of adjacent surfaces may be cut surfaces formed to provide a bent portion at an end portion of the frame on the substrate side in the first direction.

[0019] In addition, in the present invention, a plurality of non-bending portions may be provided at the end portion of the substrate side in the first direction of the frame, and in the third direction, a bending portion may be sandwiched between the non-bending portions, and a pair of adjacent surfaces may be surfaces opposite to the bending portion and of the two non-bending portions sandwiching the bending portion.

[0020] Effects of the invention:

[0021] According to the present invention, when a bending portion is provided on the frame (i.e., during cutting and bending processing), there is no need to provide cuts such as punching holes on both sides of the bending portion, thereby being able to suppress the degradation of frame performance etc. caused by the formation of the cuts.

[0047] In addition, three mutually orthogonal directions are hereinafter referred to as X, Y, and Z directions, and a direction penetrating a substrate CB described later, in other words, an up-down direction of the connector is referred to as Z direction. In addition, a surface of the substrate CB on which the connector is mounted is referred to as an XY plane, a lateral width direction (left-right direction) of the connector is referred to as an X direction, and a front-back direction of the connector is referred to as a Y direction.

[0048] In addition, for the sake of convenience, the side where the substrate CB is located when viewed from the connector in the Z direction is referred to as the "lower side", and the opposite side is referred to as the "upper side". The upper side of the connector is the "+Z side", and the lower side of the connector is the "-Z side".

[0049] In this specification, "orthogonal" and "parallel" include the error range generally allowed in the connector field, and also include states that are offset within a range of less than a few degrees (eg, 2 to 3°) relative to strict orthogonality and parallelism.

[0050] <<Structure of Connector of the Present Embodiment>>

[0051] Reference Figures 1 to 19, the structure of the connector of this embodiment (hereinafter referred to as connector 10) is described. Figure 6 Show Figure 5 The II section is a section (XZ plane) passing through the formation position of the bent portion 50 described later.

[0052] Connector 10 is Figure 1 to Figure 6 The socket connector shown, such as Figure 7 As shown, the connector 10 is fixed to the surface of the substrate CB by solder 11 and mounted on the substrate CB. Figure 8 The plug connector shown in FIG. 1 is mated with the mating connector 100. Specifically, Fig. 9 As shown, the connector 10 is mated with the mating connector 100 in the Z direction. The Z direction is the mating direction of the connector 10 and the mating connector 100, and corresponds to the "first direction" of the present invention.

[0053] like Figure 1 to Figure 5 As shown, the connector 10 includes a frame 12 having a substantially rectangular shape in a plan view, a housing 20 disposed inside the frame 12 and surrounded by the frame 12, and contacts 31 and 32 mounted on the housing 20. The frame 12 and the housing 20 will be described later.

[0054] The contact 31 is a contact for low-frequency signal transmission or power supply, and a plurality of contacts are embedded in the central portion of the housing 20 (the housing central portion 21) in the Y direction. Figure 1 In the structure shown, there are four contacts 31.

[0055] The contact 32 is a contact for high-frequency signal transmission, i.e., a terminal for RF (Radio Frequency), and one is pressed into each of the two ends (shell ends 22) of the shell 20 in the Y direction. In addition, the high frequency corresponds to a frequency bandwidth of 6 GHz or more, for example, a frequency bandwidth including a 28 GHz band for 5G (5th Generation).

[0056] In addition, if Figure 1 and Figure 7 As shown, a recessed space H is provided inside the frame 12, and when the connector 10 is engaged with the other connector 100, as shown in FIG. Fig. 9 The entire mating connector 100 is accommodated in the recessed space H. As shown in FIG.

[0057] like Figure 8As shown, the counterpart connector 100 includes: a counterpart frame 102 having a substantially rectangular shape when viewed from above; a bottom wall 104 disposed inside the counterpart frame 102; and contact holding portions 106 and 108 protruding from the bottom wall 104. The contact holding portion 106 is disposed at the center portion of the counterpart connector 100 in the Y direction, and the same number of counterpart contacts 110 as the number of contacts 31 are mounted on the contact holding portion 106. The contact holding portions 108 are disposed at both ends of the counterpart connector 100 in the Y direction, and one counterpart contact 112 is mounted on each contact holding portion 108.

[0058] The mating contact 110 corresponds to the contact 31 of the connector 10, and the mating contact 112 corresponds to the contact 32 of the connector 10. In addition, when the connector 10 and the mating connector 100 are mated, the contacts 31 and 32 are electrically connected to the corresponding mating contacts 110 and 112, respectively, so that signal transmission between the connectors can be performed.

[0059] (case)

[0060] The housing 20 is an insulator made of insulating resin. Figure 1 As shown, the housing 12 is held by the frame 12 (specifically, the housing holding portion 46 described later) in a state of being arranged in the recessed space H. Figure 1 to Figure 3 As shown, the housing 20 has: a housing center portion 21 forming a center portion in the Y direction; housing ends 22 forming a +Y side end portion and a -Y side end portion; and a housing bottom portion 23 forming a -Z side end portion.

[0061] The housing bottom 23 extends continuously in the Y direction, and the housing center portion 21 and the two housing end portions 22 extend from the housing bottom 23 so as to protrude toward the +Z side.

[0062] like Figure 1 and Figure 2 As shown, the central portion 21 of the housing has: a convex portion (central convex portion 24) located in the central portion in the X direction; and convex portions (lateral convex portions 25) arranged on both sides of the central convex portion 24 in the X direction. The central convex portion 24 and the two lateral convex portions 25 extend in the Y direction respectively, and a concave portion is provided between the central convex portion 24 and the lateral convex portions 25, and a groove for the contact 31 to be embedded is provided in the concave portion (refer to Figure 1 ).

[0063] The shell end portions 22 on the +Y side and the -Y side are symmetrical structures to each other. The structure of the shell end portion 22 on the -Y side is described by taking the example of the shell end portion 22 on the -Y side.

[0064] like Figure 1 and Figure 2 As shown, the housing end 22 is a symmetrical structure with the center position of the connector 10 in the X direction as the boundary. Fig.16As shown, the +X side portion and the -X side portion of the housing end portion 22 respectively have an inner convex portion 26 and an outer convex portion 27. The inner convex portion 26 is arranged at a position connected to the lateral convex portion 25 of the housing center portion 21 in the Y direction, and the outer convex portion 27 is arranged in parallel with the inner convex portion 26 at a position closer to the outside than the inner convex portion 26 in the Y direction.

[0065] In the housing end portion 22, the contact 32 is pressed and embedded in the gap between the outer convex portion 27 on the +X side and the outer convex portion 27 on the -X side in the X direction (see Figure 2 ). In addition, in the housing end portion 22, the housing holding portion 46 is inserted into a recessed portion provided between the inner convex portion 26 and the outer convex portion 27 (see Fig.16 ).

[0066] (frame)

[0067] like Figure 10 to Figure 12 As shown, the frame 12 is a substantially rectangular frame in a plan view, and surrounds the housing 20 in the X and Y directions. The frame 12 is made of a metal plate, for example, a copper alloy such as brass and bronze, or a stainless steel plate. The thickness of the metal plate constituting the frame 12 is set to, for example, 0.06 mm to 0.15 mm.

[0068] The lower end (the end on the -Z side) of the frame 12 is fixed to the substrate CB by solder 11. Figure 7 As shown, the solder 11 is provided along the entire periphery of the frame 12. That is, the lower end of the frame 12 (the end on the substrate CB side in the Z direction) is fixed to the substrate CB by the solder 11 over the entire periphery of the frame 12.

[0069] In addition, the frame 12 of this embodiment is a frame (housing) for electromagnetic shielding set to a ground potential. Specifically, a conductive pattern (not shown) for grounding formed in accordance with the outer shape of the frame 12 is provided on the upper surface (surface on the +Z side) of the substrate CB, and the frame 12 is fixed to the substrate CB while being carried on the conductive pattern.

[0070] In addition, as described above, the lower end of the frame 12 and the substrate CB are fixed by soldering throughout the entire periphery of the frame 12, and the gap between the frame 12 and the substrate CB is filled with solder 11 throughout the entire periphery of the frame 12. In addition, a small gap between a portion of the frame 12 that is bent to form a bent portion 50 described later (more specifically, a portion between a pair of adjacent surfaces 52 described later) and the substrate CB is also filled with solder 11. As a result, the intrusion and release of electromagnetic waves from the gap between the frame 12 and the substrate CB are suppressed, and the electromagnetic shielding property of the frame 12 is good.

[0071] like Figure 10 to Figure 14As shown, the frame 12 has a pair of long side walls 13, 14 arranged in the X direction and a pair of short side walls 15, 16 arranged in the Y direction. The long side walls 13, 14 and the short side walls 15, 16 intersect each other and are strictly orthogonal. The frame 12 has a plurality of (specifically four) corners 19, and each of the long side walls 13, 14 and each of the short side walls 15, 16 is connected by the corners 19. Figure 3 and Figure 4 As shown, each corner portion 19 may be bent into an R-shape, or may be bent at a substantially right angle into an L-shape.

[0072] The pair of long side walls 13 and 14 are arranged parallel to each other, and each extends long in the Y direction, and is a symmetrical structure with the center position of the connector 10 in the X direction as the boundary. Here, the direction penetrating the long side walls 13 and 14, that is, the X direction, corresponds to the second direction of the present invention, and is a direction that intersects with the Z direction as the first direction, or more specifically, is orthogonal. In addition, the extending direction of the long side walls 13 and 14, that is, the Y direction, corresponds to the third direction of the present invention, and is a direction that intersects with the X direction and the Z direction, or more specifically, is orthogonal.

[0073] The pair of short side walls 15 and 16 are arranged parallel to each other and extend in the X direction, respectively, and are symmetrical with the center position of the connector 10 in the Y direction as the boundary. Figure 2 and Figure 4 As shown, each short side wall 15, 16 is divided into two walls 17, 18 at the center position in the X direction of the connector 10. The two walls 17, 18 extend in the X direction and are symmetrical structures with the center position in the X direction of the connector 10 as the boundary.

[0074] like Fig.13 As shown in FIG. 1 , the two walls 17 and 18 are slightly separated in the X direction and arranged in a straight line. Figure 10 to Figure 12 As shown, the frame 12 is divided into two segments 12A and 12B of the same shape in the X direction. The two segments 12A and 12B are symmetrical with respect to the center position of the connector 10 in the X direction, and more specifically, they are mirror images. Figure 1 and Figure 2 As shown, the two segments 12A and 12B are arranged to surround the housing 20 in a state of being opposed to each other.

[0075] Below, with Fig.15 Taking the fragment 12A on the +X side (hereinafter referred to as the fragment 12A) as an example, the structures of the two fragments 12A and 12B in a mirror image relationship with each other are described. The fragment 12A is composed of a metal plate, such as Fig.15The long side wall 13 on the +X side and a pair of walls 17 disposed at both ends thereof are shown. The pair of walls 17 are the +X side walls 17 of the short side wall 15 on the +Y side and the short side wall 16 on the -Y side, respectively, and extend in the X direction (second direction). The long side wall 13 extends in the Y direction (third direction) to connect the ends of the pair of walls 17 on the outer sides of the X direction. That is, the long side wall 13 is equivalent to a connecting wall connecting the pair of walls 17.

[0076] like Figure 10 to Figure 15 As shown, the long side wall 13 and the pair of walls 17 each have a wall body 41. The wall body 41 of the long side wall 13 rises from the substrate CB to the +Z side and extends in the Y direction. The wall body 41 of the pair of walls 17 rises from the substrate CB to the +Z side and extends in the X direction. Figure 13 to Figure 15 As shown, each wall body portion 41 has a lower portion 42 located on the substrate CB side (−Z side) and an upper portion 43 extending from the lower portion 42 further toward the +Z side.

[0077] The lower portion 42 corresponds to an end portion of the frame 12 on the substrate CB side in the Z direction, and extends continuously in the Y direction. The lower end of the lower portion 42 is in contact with the substrate CB.

[0078] like Figure 13 to Figure 15 As shown, the upper portion 43 is bent into a substantially V-shape with the upper end portion directed outward (the side opposite to the side where the housing 20 is located). In other words, the upper portion 43 has a substantially V-shaped bent portion 43A at a midway position in the Z direction.

[0079] In addition, if Fig.14 As shown, the upper portion 43 of the wall body 41 constituting the long side wall 13 is divided into a plurality of parts in the Y direction, specifically, a central portion 44 and side portions 45 located closer to the +Y side and the -Y side than the central portion 44. The side portions 45 are provided with the bent portions 43A.

[0080] The bent portion 43A is provided at the upper portion 43 of the wall body 41, so that when the connectors are mated, it is easy to guide the mating connector 100 into the recessed space H of the connector 10. In addition, by providing the bent portion 43A, the contact state between the frame 12 of the connector 10 and the frame of the mating connector 100 (the mating frame 102) is stabilized when the connectors are mated.

[0081] Regarding the structure of the wall main body 41 of the long side wall 13, in more detail, Figure 10 to Figure 12 and Fig.15 As shown, a plurality of (two in the illustrated case) bent portions 50 are provided at the lower portion 42 of the wall main body 41 constituting the long side wall 13. The bent portion 50 is a portion bent toward the side where the housing 20 is located, that is, the inner side, in the X direction. Figure 6As shown in FIG. 1 , the cross-section (cross-section perpendicular to the Y direction) is roughly L-shaped. Fig.11 and Fig.12 As shown in FIG. 1 , the bent portion 50 has a certain width in the Y direction and extends straight in the X direction. Figure 6 As shown, the bent portion 50 may be bent at a substantially right angle into an L-shape, or may be bent into an R-shape (arc-shape).

[0082] The bending portion 50 is provided to integrate the housing holding portion 46 holding the housing 20 with the frame 12. Figure 10-11 As shown, the case holding portion 46 is connected to the inner end portion of the bent portion 50 in the X direction (that is, the end portion on the side where the case 20 is located).

[0083] The shell holding portion 46 stands up from the inner end of the bent portion 50 in the X direction toward the +Z side, and the Y direction end portions of the shell holding portion 46 are tapered toward the Y direction end ends. In the present embodiment, the shell holding portion 46 is continuous with the bent portion 50, that is, integrated with the frame 12, and is composed of a part of the metal plate forming the frame 12.

[0084] The assembly steps of the housing 20 with respect to the frame 12 are briefly described. Before assembly, the frame 12 approaches the housing 20 from above the housing 20, and the housing 20 enters the frame 12, that is, the recessed space H. In this process, in the housing end 22, the housing holding portion 46 is inserted into the recessed portion provided between the inner convex portion 26 and the outer convex portion 27. In addition, the two end portions of the housing holding portion 46 in the Y direction are partially sunken into the outer wall surface of the inner convex portion 26 in the Y direction and the inner wall surface of the outer convex portion 27 in the Y direction, whereby the housing holding portion 46 is assembled (engaged) with the inner convex portion 26 and the outer convex portion 27.

[0085] Furthermore, in the present embodiment, the shielding portion 47 for dealing with crosstalk is installed together with the housing retaining portion 46 on the bending portion 50. When the connector 10 is engaged with the mating connector 100, the shielding portion 47 and the mating shielding portion 114 provided on the mating connector 100 together form a shielding wall (not shown) for crosstalk. This shielding wall can suppress crosstalk of signals (more specifically, high-frequency signals) between the contacts 32 on the +Y side and the contacts 32 on the -Y side. Fig.15 As shown, the shield portion 47 is connected to the case holding portion 46 via a connection portion 48 extending from the upper end (end on the +Z side) of the case holding portion 46 , and is attached to the bent portion 50 via the case holding portion 46 and the connection portion 48 .

[0086] Furthermore, when the bent portion 50 is disposed at the lower end portion of the frame 12 (ie, the lower portion 42 of the wall main body 41), usually, as shown in FIG. Fig.21As shown, cutouts such as punching holes are provided on the base material of the frame 12 at positions corresponding to both sides of the bent portion 50. In addition, the base material of the frame 12 is cut and bent at the portion located between the cutouts. However, if the cutouts such as punching holes are formed at the lower portion of the frame 12, since electromagnetic waves enter or are released from the cutouts, the electromagnetic shielding property of the frame 12 may be impaired. In addition, the strength of the frame 12 may also be reduced due to the formation of the cutouts.

[0087] In contrast, in this embodiment, if Fig.17 and Fig.18 As shown, no cutouts are provided at both sides of the bent portion 50 , that is, both end surfaces 51 of the bent portion 50 in the Y direction are adjacent to a pair of adjacent surfaces 52 .

[0088] Specifically explain, such as Fig.18 As shown in the figure, a plurality of non-bending portions 53 are provided in the lower portion 42 of the wall main body portion 41 constituting the long side wall 13. The non-bending portion 53 is a portion of the lower portion 42 of the wall main body portion 41 adjacent to the bending portion 50 in the Y direction. In addition, the bending portion 50 (strictly speaking, the base end portion of the bending portion 50) is sandwiched between two non-bending portions 53 in the Y direction. A pair of adjacent surfaces 52 is a surface facing the bending portion 50, and is provided respectively on the two non-bending portions 53 sandwiching the bending portion 50.

[0089] More specifically, in the state of the unfolded wall main body 41 (it is easy to understand that the state before the portion to be the bent portion 50 is cut and bent), as shown in FIG. Fig.19 As shown, the portion that becomes the bent portion 50 and the portion that becomes the non-bent portion 53 are continuously arranged in the Y direction. In addition, the lower portion 42 of the wall body 41 is cut in the Z direction at the boundary position between the portion that becomes the bent portion 50 and the portion that becomes the non-bent portion 53.

[0090] Furthermore, by cutting and bending the portion of the lower portion 42 of the wall main body 41 located between the cut portions, a bent portion 50 is formed in the lower portion 42, and a pair of adjacent surfaces 52 are provided at both sides thereof to be adjacent to the two end surfaces 51 of the bent portion 50. In other words, the pair of adjacent surfaces 52 can be considered to be cut surfaces formed to provide the bent portion 50 in the lower portion 42.

[0091] In addition, in this embodiment, if Figure 10 to Figure 12 and Fig.14As shown, a plurality of bent portions 50 are provided in a symmetrical arrangement with the center position of the connector 10 in the Y direction at the lower portion 42 of the wall main body portion 41 constituting the long side wall 13. In addition, a pair of adjacent surfaces 52 is provided at the lower portion 42, the same number as the bent portions 50. And, in the Y direction, both end surfaces 51 of the plurality of bent portions 50 are adjacent to the corresponding pair of adjacent surfaces 52. The pair of adjacent surfaces 52 corresponding to the bent portions 50 are respectively provided at two non-bent portions 53 sandwiching the bent portions 50, that is, the surfaces opposite to the bent portions 50.

[0092] As described above, in this embodiment, there is no gap (notch) between the bending portion 50 and the two non-bending portions 53 sandwiching the bending portion 50. In other words, in the Y direction, the interval between the two non-bending portions 53 is roughly consistent with the width (length in the Y direction) of the bending portion 50. As a result, in the frame 12, there is no notch at the positions on both sides of the bending portion 50, thereby solving the above-mentioned problem. That is, since the intrusion and release of electromagnetic waves from the notch can be avoided, the electromagnetic shielding property of the frame 12 is improved, and as a result, the operation of the entire circuit including the connector 10 is stable.

[0093] In this embodiment, the contacts of the connector 10 include the contacts 32 for high-frequency signal transmission. Therefore, since there are no cutouts on both sides of the bent portion 50 in the frame 12, the electromagnetic shielding property of the frame 12 is improved in the high-frequency band.

[0094] In addition, as described above, the two end faces 51 of the bent portion 50 are adjacent to a pair of adjacent faces 52. Strictly speaking, the two end faces 51 of the base end portion of the bent portion 50 are adjacent to a pair of adjacent faces 52. In the portion other than the base end portion of the bent portion 50 (for example, the portion extending inward in the X direction), its two end faces can be separated from the pair of adjacent faces 52 in the X direction (the second direction).

[0095] <<Other Implementation Methods>>

[0096] The connector of the present invention is described above by using a specific example, but the above embodiment is only an example for easy understanding of the present invention, and embodiments other than the above may also be considered. For example, in the above embodiment, the number of the bending portions 50 provided on the long side walls 13 and 14 of the frame 12 is multiple (two in the case shown in the figure), and the number of the bending portions 50 is not particularly limited, as long as at least one is provided.

[0097] In addition, the bending portion 50 is not limited to the structure provided on the long side walls 13 and 14, and may also be provided on the short side walls 15 and 16. In this case, the direction penetrating the short side walls 15 and 16 (i.e., the Y direction) is the second direction, and the direction in which the short side walls 15 and 16 extend (i.e., the X direction) is the third direction.

[0098] In addition, in the above embodiment, the outer shape of the frame 12 is a rectangular shape that is long in the Y direction, but it is not limited to this. The outer shape of the frame may also be a quadrilateral other than a rectangle, such as a circle, a trapezoid, or a rhombus, or a polygon other than a quadrilateral. In addition, in the above embodiment, the frame 12 is a frame for electromagnetic shielding, but it is not limited to this. The present invention can also be applied to a frame that does not have electromagnetic shielding properties (for example, a frame that functions as a protective frame for protecting a housing and a contact).

[0099] Furthermore, in the above embodiment, the contacts 31 and 32 include the contact 32 for high-frequency signal transmission, but the present invention is not limited thereto. That is, the contacts may include only contacts for transmitting signals of a general frequency bandwidth or low-frequency signals.

[0100] In the above embodiment, the frame 12 is divided into two pieces 12A and 12B of the same shape, but the present invention is not limited thereto. For example, the frame may be composed of a continuous body (specifically, an indivisible frame body).
