Description

The present invention relates to a connector, and in particular to a connector that can be mated with a mating connector in a first direction and in which a housing that holds contacts is surrounded by a frame.

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

As shown in FIG. 20, the connector 1 is constructed by surrounding a housing 3 (insulating member) that holds contacts 2 (connection terminals) with a substantially rectangular frame 4 (fixed terminals). The frame 4 is fixed to a substrate (not shown) and is positioned opposite the side wall surface of the housing 3.

As shown in FIG. 21, protrusions 5 and 6 are provided on the bottom of the frame 4. When the frame 4 is viewed from above, the protrusions 5 and 6 are bent toward the side where the housing 3 is located (i.e., toward the inside). The tips of the protrusions 5 and 6 are inserted into predetermined positions on the housing 3, so that the housing 3 is held by the frame 4, more specifically, by the protrusions 5 and 6.

JP 2016-12553 Publication

As shown in FIG. 21, the frame 4 has cutouts, specifically punched holes 7, formed on both sides of the projections 5 and 6. The punched holes 7 are provided to provide the protrusions 5 and 6, that is, they are provided for the purpose of cutting and bending the sheet metal that constitutes the frame 4 to form the protrusions 5 and 6. It is a hole. By providing the punched holes 7, it becomes relatively easy to form the protrusions 5 and 6 on the frame 4, that is, to cut and bend the frame 4, and since a through hole is formed in the frame 4, it is possible to form a frame with shielding properties. There is a possibility that the performance of the frame 4 and the strength of the frame 4 may deteriorate.

The present invention was made in consideration of the above circumstances, and aims to achieve the following objectives. The present invention aims to provide a connector that solves the problems of the above-mentioned conventional technology and has a bent portion on the frame while ensuring the performance of the frame.

To achieve the above object, the connector of the present invention is a connector that can be fitted with a mating connector in a first direction, and includes a housing to which a contact is attached, and an end in the first direction fixed to a substrate; and a frame surrounding the housing, and a bent part bent in a second direction intersecting the first direction, and a bent part bent in a second direction intersecting the first direction, and a bent part bent in a second direction intersecting the first direction, and a bent part bent in a second direction intersecting the first direction. A pair of adjacent surfaces adjacent to both end surfaces of the bent portion in a third direction intersecting each of the directions are provided.

According to the connector of the present invention configured as described above, the bent portion is provided at the end of the frame on the board side in the first direction, and both end surfaces of the bent portion are arranged on both sides of the bent portion. Adjacent to a side surface (adjacent surface). In other words, since there are no cutouts such as punched holes on both sides of the bent portion, it is possible to suppress deterioration in the performance of the frame due to the formation of the cutouts.

Further, in the connector of the present invention, the frame is preferably an electromagnetic shielding frame set to a ground potential. In this case, the effects of the present invention will be more significant. That is, since there are no notches on both sides of the bent portion of the frame, the electromagnetic shielding properties of the frame are improved. As a result, the operation of the circuit including the connector becomes stable.

Furthermore, in the connector of the present invention, the end of the frame on the substrate side in the first direction may be fixed to the substrate by solder provided along the entire outer periphery of the frame. In this case, since the solder is provided over the entire outer periphery of the frame, it is possible to fill minute gaps and the like that exist near the bent portions of the frame with the solder. As a result, the electromagnetic shielding properties of the frame are further improved.

Further, in the connector of the present invention, the bent portion is bent toward the side where the housing is located in the second direction, and the end portion of the bent portion on the side where the housing is located in the second direction has the housing. A housing holding portion holding the housing may be connected. In this case, a bent portion is required to integrate the housing holding portion with the frame, and the present invention in which the bent portion is provided in the frame without providing a cutout is more effective.

In addition, in the connector of the present invention, the contacts may include contacts for transmitting high-frequency signals. In this case, the frame is used as an electromagnetic shield in the high-frequency band, so the effect of improving the electromagnetic shielding properties of the frame becomes even more pronounced.

Further, in the present invention, the frame is divided into two pieces having the same shape, and each of the two pieces has a gap between a pair of walls extending in the second direction and a pair of walls extending in the third direction. a connecting wall connecting the two pieces, and the two pieces may be arranged opposite each other to surround the housing.

In addition, in the present invention, the end of the frame facing the substrate in the first direction may be provided with multiple bends and a pair of adjacent surfaces, the same number as the number of bends. In this case, both end surfaces of each of the multiple bends may be adjacent to a corresponding pair of adjacent surfaces in the third direction. This makes it possible to suppress deterioration in the performance of the frame, even when multiple bends are provided on the frame.

In the present invention, each of the pair of adjacent surfaces may be a cut surface formed to provide a bent portion at the end of the frame on the substrate side in the first direction.

In addition, in the present invention, a plurality of non-bending sections are provided on the end of the frame on the substrate side in the first direction, and a bending section is sandwiched between the non-bending sections in the third direction, and the pair of adjacent surfaces are preferably surfaces facing the bending sections of the two non-bending sections that sandwich the bending section.

According to the present invention, when providing a bent portion in a frame (i.e., during cutting and bending), it is not necessary to provide notches such as punched holes on both sides of the bent portion, so degradation of the performance of the frame due to the formation of notches can be suppressed.

(housing)
The housing 20 is an insulator made of insulating resin, and is held by the frame 12 (more specifically, the housing holding portion 46 described below) while being disposed in the recessed space H as shown in Fig. 1. As shown in Figs. 1 to 3, the housing 20 has a housing center portion 21 forming the center in the Y direction, housing ends 22 forming the +Y side end and the -Y side end, and a housing bottom portion 23 forming the -Z side end.

The housing bottom portion 23 extends continuously in the Y direction, and the housing center portion 21 and the two housing end portions 22 each protrude and extend from the housing bottom portion 23 toward the +Z side.

As shown in Figures 1 and 2, the housing central portion 21 has a convex portion (central convex portion 24) in the center in the X direction, and convex portions (lateral convex portions 25) disposed 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 each extend in the Y direction, and a concave portion is provided between the central convex portion 24 and the lateral convex portions 25, and the concave portion has a groove for fitting the contact 31 (see Figure 1).

The +X side portion and the -X side portion of the housing end 22 each have an inner convex portion 26 and an outer convex portion 27, as shown in Fig. 16. The inner convex portion 26 is disposed at a position continuous with the lateral convex portion 25 of the housing central portion 21 in the Y direction, and the outer convex portion 27 is disposed next to the inner convex portion 26 at a position outer than the inner convex portion 26 in the Y direction.

In the housing end portion 22, a contact 32 is press-fitted inward in the X direction into a gap between the outer protrusion 27 on the +X side and the outer protrusion 27 on the −X side (see FIG. 2). Further, in the housing end portion 22, a housing holding portion 46 is inserted into a recess provided between the inner convex portion 26 and the outer convex portion 27 (see FIG. 16).

(flame)
10 to 12, the frame 12 is a substantially rectangular frame in 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 or 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.

The bottom end (the end on the -Z side) of the frame 12 is fixed to the board CB by solder 11. As shown in FIG. 7, the solder 11 is provided along the entire outer periphery of the frame 12. In other words, the bottom end of the frame 12 (the end on the board CB side in the Z direction) is fixed to the board CB by solder 11 along the entire outer periphery of the frame 12.

Furthermore, the frame 12 in this embodiment is a frame (shell) for electromagnetic shielding that is set to ground potential. To be more specific, a conductive pattern for grounding (not shown) formed to match the external shape of the frame 12 is provided on the upper surface (+Z side surface) of the substrate CB, and the frame 12 is fixed to the substrate CB while being placed on this conductive pattern.

As described above, the lower end of the frame 12 and the board CB are fixed with solder over the entire outer periphery of the frame 12, and the gap between the frame 12 and the board CB is is filled with solder 11. Furthermore, the slight gap between the part of the frame 12 that is bent to form a bent part 50 (more specifically, the part between a pair of adjacent surfaces 52, which will be described later) and the board CB is also filled with solder. It is filled by 11. This suppresses the intrusion and emission of electromagnetic waves from the gap between the frame 12 and the substrate CB, and improves the electromagnetic shielding properties of the frame 12.

As shown in Figures 10 to 14, the frame 12 has a pair of long side walls 13, 14 aligned in the X direction, and a pair of short side walls 15, 16 aligned in the Y direction. The long side walls 13, 14 and the short side walls 15, 16 intersect with each other and are orthogonal to each other strictly speaking. The frame 12 has multiple corners 19 (specifically, four), and each of the long side walls 13, 14 and each of the short side walls 15, 16 are connected at the corners 19. Each corner 19 may be curved in an R shape as shown in Figures 3 and 4, or may be bent at an approximately right angle in an L shape.

The pair of long side walls 13, 14 are arranged parallel to each other, each extending long in the Y direction, and have a symmetrical structure with respect to the center position of the connector 10 in the X direction. Here, the direction penetrating the long side walls 13, 14, i.e., the X direction, corresponds to the second direction of the present invention, and intersects with the first direction, the Z direction, and is more specifically, perpendicular to it. The extension direction of the long side walls 13, 14, i.e., the Y direction, corresponds to the third direction of the present invention, and intersects with each of the X direction and the Z direction, and is more specifically, perpendicular to it.

The pair of short side walls 15 and 16 are arranged parallel to each other, extend in the X direction, and have a symmetrical structure with respect to the center position of the connector 10 in the Y direction. Each short side wall 15, 16 is divided into two walls 17, 18 at the center position of the connector 10 in the X direction, as shown in FIGS. 2 and 4. The two walls 17 and 18 extend in the X direction and have a symmetrical structure with the center position of the connector 10 in the X direction as a border.

As shown in FIG. 13, the two walls 17 and 18 are arranged in a straight line with some distance in the X direction. In other words, the frame 12 is divided into two pieces 12A and 12B having the same shape in the X direction as shown in FIGS. 10 to 12. The two pieces 12A and 12B have a symmetrical shape with respect to the center position of the connector 10 in the X direction, and are in a mirror image relationship. The two pieces 12A and 12B are arranged facing each other so as to surround the housing 20, as shown in FIGS. 1 and 2.

The configuration of the two pieces 12A, 12B, which are mirror images of each other, will be described below using the +X side piece 12A (hereinafter simply referred to as piece 12A) shown in FIG. 15 as an example. Piece 12A is made of a single metal plate, and as shown in FIG. 15, has a +X side long side wall 13 and a pair of walls 17 arranged on both ends. The pair of walls 17 are +X side walls 17 that are respectively possessed by the +Y side short side wall 15 and the -Y side short side wall 16, and extend in the X direction (second direction). The long side wall 13 extends in the Y direction (third direction), and connects the outer ends of each of the pair of walls 17 in the X direction. In other words, the long side wall 13 corresponds to a connecting wall that connects the pair of walls 17.

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

The lower portion 42 corresponds to the end of the frame 12 on the substrate CB side in the Z direction, extends continuously in the Y direction, and the lower end of the lower portion 42 is in contact with the substrate CB.
As shown in FIGS. 13 to 15, the upper portion 43 is bent in a substantially V-shape such that the upper end portion faces outward (to 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 an intermediate position in the Z direction.

As shown in FIG. 14, the upper portion 43 of the wall body portion 41 constituting the long side wall 13 is divided into a plurality of portions in the Y direction, specifically, into a central portion 44 and side portions 45 located on the +Y side and -Y side of the central portion 44. Of these, the side portion 45 is provided with the bent portion 43A described above.

By providing the bent portion 43A on the upper portion 43 of the wall body portion 41, it becomes easier to guide the mating connector 100 into the recessed space H of the connector 10 when the connectors are mated. In addition, by providing the bent portion 43A, the contact state between the frame 12 of the connector 10 and the frame (mating frame 102) of the mating connector 100 is stable when the connectors are mated.

To explain in more detail the structure of the wall main body part 41 of the long side wall 13, the lower part 42 of the wall main body part 41 constituting the long side wall 13 has a plurality of (not shown) as shown in FIGS. In the case, two bending portions 50 are provided. The bent portion 50 is a portion bent toward the side where the housing 20 is located in the X direction, that is, toward the inside, and its cross section (cross section perpendicular to the Y direction) is approximately L-shaped as shown in FIG. It is in a state of As shown in FIGS. 11 and 12, the bent portion 50 has a slight width in the Y direction and extends straight in the X direction. The bent portion 50 may be bent at a substantially right angle into an L shape as shown in FIG. 6, or may be bent into an R shape (arc shape).

The bent portion 50 is provided to integrate the housing holding portion 46 that holds the housing 20 with the frame 12. Specifically, as shown in FIGS. 10 and 11, the housing holding portion 46 is connected to the inner end in the X direction of the bent portion 50 (that is, the end on the side where the housing 20 is located). There is.

The housing holding portion 46 rises from the inner end of the bent portion 50 in the X direction toward the +Z side, and both Y direction end portions of the housing holding portion 46 are tapered toward the Y direction ends. In this embodiment, the housing holding portion 46 is continuous with the bent portion 50, i.e., it is integrated with the frame 12, and is formed by a part of the metal plate that forms the frame 12.

To outline the procedure for assembling the housing 20 to the frame 12, the frame 12 before being assembled is approached to the housing 20 from above the housing 20, and the housing 20 enters the inside of the frame 12, that is, the recessed space H. In the process, the housing holding portion 46 is inserted into the recess provided between the inner convex portion 26 and the outer convex portion 27 at the housing end portion 22 . Then, both end portions of the housing holding portion 46 in the Y direction bite into the outer wall surface of the inner protrusion 26 in the Y direction and the inner wall surface of the outer protrusion 27 in the Y direction, so that the housing holding portion 46 is moved between the inner protrusion 26 and the outer protrusion 27. be assembled (engaged).

In this embodiment, a shielding portion 47 for preventing crosstalk is attached to the bent portion 50 together with the housing holding portion 46. When the connector 10 is mated with the mating connector 100, the shielding portion 47 forms a shielding wall (not shown) for crosstalk together with the mating shielding portion 114 provided on the mating connector 100. This shielding wall can suppress crosstalk of signals (more specifically, high-frequency signals) between the +Y side contacts 32 and the -Y side contacts 32. As shown in FIG. 15, the shielding portion 47 is connected to the housing holding portion 46 by a connecting portion 48 extending from the upper end (end on the +Z side) of the housing holding portion 46, and is attached to the bent portion 50 via the housing holding portion 46 and the connecting portion 48.

By the way, when the above-mentioned bent part 50 is provided at the lower end of the frame 12 (that is, the lower part 42 of the wall main body part 41), normally, as shown in FIG. 21, at positions corresponding to both sides of the bent part 50, A cutout such as a punched hole is provided in the base material of the frame 12. Then, a portion of the base material of the frame 12 located between the notches is cut and bent. However, if a cutout such as a punched hole is formed in the lower part of the frame 12, electromagnetic waves may enter or be emitted from the cutout, which may impair the electromagnetic shielding properties of the frame 12. Furthermore, the strength of the frame 12 may be reduced due to the formation of the notch.

On the other hand, in this embodiment, as shown in FIGS. 17 and 18, the notches are not provided at both sides of the bent portion 50, and in other words, the two end surfaces 51 of the bent portion 50 in the Y direction are is adjacent to the adjacent surface 52 of.

Specifically, the lower portion 42 of the wall main body portion 41 constituting the long side wall 13 is provided with a plurality of non-bending portions 53 as shown in FIG. 18. The non-bending portions 53 are portions of the lower portion 42 of the wall main body portion 41 that are adjacent to the bending portion 50 in the Y direction. In the Y direction, the bending portion 50 (strictly speaking, the base portion of the bending portion 50) is sandwiched between the two non-bending portions 53. The pair of adjacent surfaces 52 are surfaces facing the bending portion 50, and are provided on each of the two non-bending portions 53 that sandwich the bending portion 50.

To explain in more detail, when the wall main body portion 41 is unfolded (for ease of understanding, the state before the portion that will become the bent portion 50 is cut and bent), the portion that will become the bent portion 50 and the non-bent portion are separated as shown in FIG. 53 are continuously lined up in the Y direction. Furthermore, at the boundary between the portion that will become the bent portion 50 and the portion that will become the non-bent portion 53, the lower portion 42 of the wall main body portion 41 is cut in the X direction.

Then, by cutting and bending the portion of the lower portion 42 of the wall body portion 41 located between the cut portions, a bent portion 50 is formed in the lower portion 42, and a pair of adjacent surfaces 52 adjacent to both end faces 51 of the bent portion 50 are provided on both sides of the bent portion 50. In other words, each of the pair of adjacent surfaces 52 can be said to be a cut surface formed to provide the bent portion 50 in the lower portion 42.

In this embodiment, as shown in Figures 10 to 12 and 14, a plurality of bent portions 50 are provided on the lower portion 42 of the wall body portion 41 constituting the long side wall 13, so as to be symmetrically arranged with respect to the center position in the Y direction of the connector 10. The lower portion 42 is also provided with a pair of adjacent surfaces 52, the same number as the number of bent portions 50. In the Y direction, both end surfaces 51 of each of the plurality of bent portions 50 are adjacent to a corresponding pair of adjacent surfaces 52. The pair of adjacent surfaces 52 corresponding to the bent portion 50 is provided on each of the two non-bent portions 53 that sandwich the bent portion 50, that is, they are the opposing surfaces to the bent portion 50.

As described above, in this embodiment, there is no gap (notch) between the bent portion 50 and the two non-bent portions 53 that sandwich the bent portion 50. In other words, the distance between the two non-bent portions 53 in the Y direction is approximately equal to the width (length in the Y direction) of the bent portion 50. In this way, the absence of notches on either side of the bent portion 50 in the frame 12 solves the above-mentioned problem. In other words, the intrusion and emission of electromagnetic waves from the notches can be prevented, improving the electromagnetic shielding properties of the frame 12, and as a result, the operation of the entire circuit including the connector 10 is stabilized.

In this embodiment, the contacts of the connector 10 include contacts 32 for transmitting high-frequency signals. Therefore, the absence of notches on either side of the bent portion 50 in the frame 12 improves the electromagnetic shielding properties of the frame 12 in the high-frequency band.

Note that both end surfaces 51 of the bent portion 50 and the pair of adjacent surfaces 52 are adjacent to each other as described above, but strictly speaking, both end surfaces 51 of the root portion of the bent portion 50 and the pair of adjacent surfaces 52 are adjacent to each other. are doing. In the bent portion 50, both end surfaces of a portion other than the root portion (for example, a portion extending inward in the X direction) may be separated from the pair of adjacent surfaces 52 in the X direction (second direction).

For example, in the above-described embodiment, the number of bent portions 50 provided on the long side walls 13 and 14 of the frame 12 is plural (two in the illustrated case), but the number of bent portions 50 is particularly limited. However, at least one or more may be provided.

Furthermore, the configuration is not limited to one in which the bending portion 50 is provided on the long side walls 13, 14, but may be one in which the bending portion 50 is provided on the short side walls 15, 16. In this case, the direction passing through the short side walls 15, 16 (i.e., the Y direction) is the second direction, and the direction in which the short side walls 15, 16 extend (i.e., the X direction) is the third direction.

In the above embodiment, the outer shape of the frame 12 is a rectangle that is long in the Y direction, but this is not limited to this. The outer shape of the frame may be a circle, a trapezoid, a diamond, or any other quadrangle, or a polygon other than a quadrangle. In the above embodiment, the frame 12 is an electromagnetic shielding frame, but this is not limited to this. The present invention is also applicable to frames that do not have electromagnetic shielding properties (for example, a frame that functions as a protective frame to protect the housing and contacts).

Further, in the above-described embodiment, the contacts 31 and 32 include the contact 32 for high frequency signal transmission, but the present invention is not limited to this. That is, the contacts may include only contacts that transmit signals in a general frequency band or low frequency signals.

Further, in the above-described embodiment, the frame 12 is configured to be divided into two pieces 12A and 12B having the same shape, but the present invention is not limited to this. For example, the frame may be composed of one continuous body (specifically, an indivisible frame body).
