Description

Technical Field

[0001] The present disclosure relates to connectors and connector pairs. Background Art

[0002] Connectors such as substrate-to-substrate connectors have been used to electrically connect a pair of parallel circuit substrates to each other. These connectors are attached to the respective opposite surfaces of a pair of circuit substrates and fit together to achieve conduction. In addition, a technology has been proposed in which a reinforcing fitting used as a power terminal attached to both ends to transmit the current of the power supply between the connector and the mating connector is used (for example, see Patent Document 1).

[0003] Fig.11 is a perspective view showing a conventional connector.

[0004] In the figure, 811 represents a base of a plug connector as a connector mounted on the surface of a first circuit substrate (not shown), which has a pair of protrusions 812 for inserting a socket connector mounted on the surface of a second circuit substrate (not shown). The protrusions 812 are convex strips extending in the length direction of the base 811, and a plurality of terminals 861 are arranged side by side at a predetermined pitch and supported.

[0005] Furthermore, reinforcing fittings 851 are attached to both ends in the length direction of the base 811. The reinforcing fittings 851 protect both ends in the length direction of the base 811 and also serve as power terminals for transmitting current of power supply by contacting reinforcing fittings of a socket connector not shown in the figure.

[0006] In addition, the reinforcing fitting 851 includes: an upper part 852, which covers a part of the upper surface of the base 811; an end part 853, whose upper end is connected to the upper part 852 via a bent part and extends in a direction orthogonal to the upper part 852 to cover a part of the end surface of the base 811; and a first side part 854 and a second side part 855, which are connected to the upper part 852 and extend in a direction orthogonal to the upper part 852 to cover a part of the side surfaces on both the left and right sides of the base 811. The lower end of the first side part 854 is connected to a power connection pad formed on the surface of the first circuit substrate not shown in the figure by welding or the like. In addition, when the plug connector is mated with the socket connector, the second side part 855 contacts and conducts the reinforcing fitting of the socket connector.

[0009] [Patent Document 1] Japanese Unexamined Patent Application 2015-185541 Summary of the invention

[0010] However, with the aforementioned conventional connector, it is difficult to correctly control the positions of the outer side surfaces of the first side surface portion 854 and the outer side surfaces of the second side surface portion 855 of the reinforcing fitting 851 with respect to the connector width direction.

[0011] The reinforcing accessory 851 is formed by stamping a metal plate to form a generally flat element in which an upper portion 852, an end portion 853, a first side portion 854 and a second side portion 855 are integrally connected, and then the generally flat element is bent so that the end portion 853, the first side portion 854 and the second side portion 855 are orthogonal to the upper portion 852.

[0012] At this time, for example, in order to form the outer side of the first side portion 854 and the outer side of the second side portion 855 in a flush manner, the first side portion 854 and the second side portion 855 at the sides of the left and right sides of the upper portion 852 are close to each other. Therefore, the bending process is performed simultaneously by the same mold component. However, these components are independent of each other, and therefore, the curvature is not strictly the same. Thus, it is difficult to make the outer side of the first side portion 854 and the outer side of the second side portion 855 strictly flush. In addition, for example, in order to make the position of the first side portion 854 deviate from the position of the second side portion 855 in the width direction of the connector, it is necessary to perform processing of different curvatures on the first side portion 854 and the second side portion 855. However, the first side portion 854 and the second side portion 855 are close to each other, and therefore, it is difficult to independently perform high-precision bending processing on the first side portion 854 and the second side portion 855.

[0013] In particular, in recent years, as connectors have become miniaturized and low-profile, the various parts of the reinforcing accessory 851 have also become miniaturized, and it has been extremely difficult to accurately control the position of the outer side surfaces of the first side portion 854 and the outer side surfaces of the second side portion 855 with respect to the width direction of the connector by performing high-precision bending processing on the first side portion 854 and the second side portion 855 which are miniature and close to each other on the left and right sides of the upper portion 852.

[0014] Here, in order to solve the problems of conventional connectors, an object of the present invention is to provide a highly reliable connector and a connector pair, which are provided with a reinforcing fitting having correct dimensional accuracy while exhibiting high strength and achieving high shielding effect and having a small and low profile.

[0015] Therefore, the connector includes a connector body, terminals attached to the connector body, and a reinforcement accessory attached to the connector body, wherein the connector body includes an engaging guide portion formed at both ends in the length direction, and the engaging guide portion is engaged with a mating engaging guide portion formed at both ends in the length direction of the mating connector body of the mating connector, and the reinforcement accessory includes: an upper portion, covering at least a portion of the upper surface of the engaging guide portion; an end portion, covering at least a portion of the end surface of the engaging guide portion; a first side portion, covering at least a portion of each side surface of the engaging guide portion; and a second side portion, covering at least a portion of each side surface of the engaging guide portion, and the end portion is connected to the upper portion, the first side portion is connected to the upper portion, and the second side portion is located closer to the end surface of the engaging guide portion than the first side portion and is connected to the end portion.

[0016] In another connector, the upper end of the end surface portion is connected to the upper surface portion via a rear bend portion, the upper end of the first side surface portion is connected to the upper surface portion via a front bend portion, and the rear end of the second side surface portion is connected to the end surface portion via a side bend portion.

[0017] In addition, in another connector, the upper portion includes a front connecting piece connected to the left and right sides of its front end, the upper end of each of the first side portions is connected to the end of each of the front connecting pieces via the front bent portion and extends in the up and down direction, the end portion includes two side connecting pieces connected to the left and right side ends, and the rear end of each of the second side portions is connected to the end of each of the side connecting pieces via the front bent portion and extends in the up and down direction.

[0018] In addition, in another connector, the upper portion includes an insertion recess formed on both side edges in the width direction thereof, and each of the second side portions includes an upper end bent portion connected to its upper end and an auxiliary piece connected to the end of the upper end bent portion and extending downward or obliquely downward, and the auxiliary piece is inserted into the insertion recess.

[0019] In addition, in another connector, the second side portion includes an upper end bent portion connected to its upper end and an auxiliary piece connected to the end of the upper end bent portion and extending downward or obliquely downward, and at least a portion of the auxiliary piece is inserted into a recess formed on the mating guide portion.

[0020] In addition, in another connector, the tail portion of the connection pad connected to the substrate is connected to the lower end of the first side portion, the lower protrusion of the connection pad connected to the substrate is connected to the lower end of the end face portion, and an obstacle portion that prevents solder climbing or flux climbing is formed on the side of the first side portion and the end face portion.

[0021] Furthermore, in another connector, a gold plating layer is applied on a nickel base plating layer on the side surfaces of the first side surface portion and the end surface portion, and the barrier portion is a portion where nickel is exposed on the surface.

[0022] The connector pair includes a connector according to the present disclosure and a mating connector that fits with the connector.

[0023] According to the present disclosure, a connector may be provided with a reinforcing fitting that is small and low profile yet exhibits high strength and correct dimensional accuracy to improve reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] The embodiments are described in detail below with reference to the accompanying drawings.

[0101] Figure 1 is a perspective view of a first connector according to the present embodiment; Figure 2a and Figure 2b are two-side views showing the first connector according to the present embodiment; Figure 3 is an exploded view of the first connector according to the present embodiment; Figure 4 is an exploded view of the second connector according to the present embodiment; Figure 5 1 is a perspective view showing a state before the first connector and the second connector according to the present embodiment are engaged. Figure 2a and Figure 2b middle, Figure 2a is a plan view, and Figure 2b It is a side view.

[0102] In the figure, the first connector 1 is a connector of the first embodiment, and is one of a pair of substrate-to-substrate connectors as a connector pair. The first connector 1 is a surface-mounted connector mounted on the surface of a first substrate (not shown), the first substrate is a substrate as a mounting element, and the first connector 1 is engaged with a second connector 101, which is a mating connector of the connector pair. In addition, the second connector 101 is the other of a pair of substrate-to-substrate connectors, and is a surface-mounted connector mounted on the surface of a second substrate (not shown), the second substrate is a substrate as a mounting element, and the second connector 101 is engaged with the first connector 1.

[0103] The first connector 1 and the second connector 101 of this embodiment are preferably used to electrically connect the first substrate and the second substrate, and can also be used to electrically connect other components. For example, the first substrate and the second substrate are each a printed circuit substrate, a flexible flat cable (FFC), a flexible circuit substrate (FPC), etc. used in electronic equipment, etc., but can be any type of substrate.

[0104] Note that in the present embodiment, expressions indicating directions such as up, down, left, right, front, and rear, etc., used to explain the configuration and actions of the various parts of the first connector 1 and the second connector 101 are relative rather than absolute, and are appropriate when the various parts of the first connector 1 and the second connector 101 are in the postures shown in the figures. However, when their postures change, these directions should be interpreted variably according to the change in posture.

[0105] The first connector 1 is a so-called plug connector type, and includes a first base 11 as a connector body, which is integrally formed of an insulating material such as a synthetic resin. As shown in the figure, the first base 11 has a substantially rectangular parallelepiped in the shape of a substantially rectangular thick plate. An elongated groove portion 13 extending in the length direction (X-axis direction) of the first base 11 and a first convex portion 12 as an elongated convex portion that defines the outer side of the groove portion 13 and extends in the length direction of the first base 11 are integrally formed on the side of the first base 11 where the second connector 101 is embedded (i.e., the side of the fitting surface 11a (Z-axis positive direction side)). The first convex portion 12 is formed along both sides of the groove portion 13 and along both sides of the first base 11. For example, the first connector 1 has dimensions of approximately 10.0 mm in length, approximately 1.1 mm in width, and approximately 0.5 mm in thickness. However, these dimensions can be appropriately changed.

[0106] A first terminal 61 as a terminal is attached to each first convex portion 12. A plurality of (e.g., 25) first terminals 61 are formed on both sides of the left and right sides at a predetermined pitch (e.g., about 0.35 mm). The pitch and number of the first terminals 61 can be appropriately changed. In the recessed portion 13, the side mounted on the first substrate (i.e., the mounting surface 11b side (Z-axis negative direction side)) is closed by the bottom plate.

[0107] The first terminal 61 can be held while being pressed into the first base 11. However, here, the first terminal 61 will be described as an element integrated with the first base 11 by overmolding (insert molding). In other words, the first base 11 is formed by setting the first terminal 61 inside and then filling the cavity of the metal mold with resin. Therefore, it is noted that although the first terminal 61 is not separated from the first base 11, for convenience, Figure 3 In FIG. 6 , the first terminal 61 is shown separated from the first base 11 .

[0108] The first terminal 61 is an integrally formed element by stamping, bending, etc. a conductive metal plate, and includes a first contact portion 65, a connecting portion 64 connected to the upper end of the first contact portion 65, a second contact portion 66 connected to the outer end of the connecting portion 64, and a tail portion 62 connected to the lower end of the first contact portion 65. The tail portion 62 extends toward the outside of the first base 11 and is connected to a connection pad by welding, etc., and the connection pad is connected to a conductive trace of the first substrate. The conductive trace is typically a signal line. In addition, the surfaces of the first contact portion 65, the connecting portion 64, and the second contact portion 66 are exposed to the side surfaces of the first convex portion 12 and the mating surface 11a.

[0109] The first protruding end portions 21 as the fitting guide portions are respectively arranged at both ends in the length direction of the first base 11. The first protruding end portions 21 are thick members extending in the width direction (Y-axis direction) of the first base 11, and both ends of the first protruding end portions 21 are connected to both ends in the length direction of the first convex portion 12, and the upper surface of the first protruding end portions 21 has a substantially rectangular shape. In a state where the first connector 1 and the second connector 101 are fitted together, the first protruding end portions 21 serve as fitting recesses 122 into which the insertion convex portion is inserted into the second protruding end portions 121 included in the second connector 101. The first reinforcing fitting 51 is attached to the first protruding end portions 21 as a reinforcing fitting.

[0110] The first reinforcing member 51 is an integrally formed member by stamping, bending, or the like on a metal plate, and includes: an upper portion 52 covering at least a portion of the upper surface 21a of the first protruding end portion 21; an end portion 53 covering at least a portion of the end surface 21c, which is a surface of the first protruding end portion 21 on the outer side in the length direction of the first base 11; and a first side portion 54 and a second side portion 55, which are side portions covering at least a portion of both side surfaces 21d, which are both surfaces of the first protruding end portion 21 on the outer side in the width direction (Y-axis direction) of the first base 11. Note that a tail portion 54a extending toward the outer side in the width direction of the first base 11 is connected to the lower end of the first side portion 54.

[0111] The upper surface portion 52 is a flat plate extending parallel to the fitting surface 11a and the mounting surface 11b. In addition, the end surface portion 53 is a flat plate connected to the outer edge of the length direction of the first base 11 at the upper surface portion 52 and extending toward the mounting surface 11b (negative direction of the Z axis). In addition, the first side surface portion 54 is a flat plate connected to the outer edge of the width direction of the first base 11 at the upper surface portion 52 and extending toward the mounting surface 11b. Note that the second side surface portion 55, which is a flat plate substantially parallel to the first side surface portion 54 and extending toward the mounting surface 11b, is connected to the outer edge of the width direction of the first base 11 at the end surface portion 53.

[0112] Furthermore, the end face recess 22a is formed on the end face 21c of the first protruding end portion 21, and the first side face recess 22b and the second side face recess 22c are formed on the side face 21d of the first protruding end portion 21. Furthermore, when the first reinforcing fitting 51 is attached to the first protruding end portion 21, the first reinforcing fitting 51 is Figure 3 The position shown is lowered relative to the first base 11, the end surface portion 53 is inserted into and accommodated in the end surface recess 22a, and the first side surface portion 54 and the second side surface portion 55 are inserted into and accommodated in the first side surface recess 22b and the second side surface recess 22c. Note that the recess 21b is formed on the upper surface 21a of the first protruding end portion 21, and at least the lower end of the auxiliary piece 55e described later provided by the second side surface portion 55 is inserted into and accommodated in the recess 21b.

[0113] The tail portion 54a of the first side surface portion 54 is connected to a connection pad by welding or the like, and the connection pad is connected to a conductive trace of the first substrate. The conductive trace is typically a power line or a ground line. The lower end of the end surface portion 53 is also connected to a connection pad of the first substrate by welding or the like.

[0114] The second connector 101 is a so-called socket connector type, and includes a second base 111 integrally formed of an insulating material such as synthetic resin as a mating connector body. As shown in the figure, the second base 111 has a generally rectangular parallelepiped in the shape of a generally rectangular thick plate, and a generally rectangular recess 112 for the first base 11 of the first connector 1 to be embedded is formed on the side where the first connector 1 is embedded (i.e., the mating surface 111a side (Z-axis negative direction side)), and the recess 112 is surrounded. For example, the second connector 101 has a length (dimension in the X-axis direction) of approximately 11.0 mm, a width (dimension in the Y-axis direction) of approximately 1.9 mm, and a thickness (dimension in the Z-axis direction) of approximately 0.6 mm. However, these dimensions can be appropriately changed.

[0115] The second protrusion 113 embedded in the groove 13 of the first connector 1 as an island is formed integrally with the second base 111 in the recess 112, and the side wall 114 extending parallel to the second protrusion 113 is formed integrally with the second base 111 on both sides (the Y-axis positive direction side and the Y-axis negative direction side) of the second protrusion 113. The second protrusion 113 and the side wall 114 protrude upward (Z-axis negative direction) from the bottom plate defining the bottom surface of the recess 112 and extend in the length direction (X-axis direction) of the second base 111. As a result, the recess 112a is formed on both sides of the second protrusion 113 as a slender recess extending in the length direction of the second base 111 with a part of the recess 112.

[0116] The second terminal receiving inner cavity 115a having a groove shape is formed on the side surfaces of both sides of the second convex portion 113. The second terminal receiving outer cavity 115b having a groove shape is formed on the side surface of the inner side of the side wall portion 114. The second terminal receiving inner cavity 115a and the second terminal receiving outer cavity 115b are connected together at the bottom surface of the groove portion 112a and integrated with each other, so that the second terminal receiving inner cavity 115a and the second terminal receiving outer cavity 115b are described as the second terminal receiving cavity 115 when collectively described. The second terminal receiving cavity 115 is formed to penetrate the bottom plate in the plate thickness direction (Z-axis direction).

[0117] In the first embodiment, the second terminal receiving chambers 115 are formed on both sides of the width direction (Y-axis direction) of the second base 111 and are arranged in the length direction of the second base 111. Specifically, only the same number of terminals are formed on both sides of the second protrusion 113 at the same pitch as the pitch of the first terminals 61 of the first connector 1. The pitch and number of the second terminal receiving chambers 115 can be appropriately changed. In addition, only the same number of second terminals 161 as terminals, which are received in their respective second terminal receiving chambers 115 and attached to the second base 111, are also arranged on both sides of the second protrusion 113 at the same pitch.

[0118] The second terminal 161 is an integrally formed element by stamping, bending, or the like on a conductive metal plate, and includes a retained portion 163, a tail portion 162 connected to the lower end of the retained portion 163, an upper connecting portion 167 connected to the upper end of the retained portion 163, a second contact portion 166 connected to the lower end of the upper connecting portion 167 and opposite to the retained portion 163, a lower connecting portion 164 connected to the lower end of the second contact portion 166, and an inner connecting portion 165 connected to the end of the lower connecting portion 164 on the opposite side of the second contact portion 166.

[0119] The held portion 163 is a portion that is embedded in and held in the second terminal receiving outer cavity 115b and extends in the fitting direction (Z-axis direction) (i.e., in the thickness direction of the second base 111). The tail portion 162 is bent and connected to the held portion 163, extends in the left-right direction (Y-axis direction) (i.e., to the outside of the width direction of the second base 111), and is connected to the connection pad by welding, etc., and the connection pad is connected to the conductive trace of the second substrate. The conductive trace is typically a signal line. The upper connecting portion 167 is a portion that is bent to protrude upward (in the negative direction of the Z-axis).

[0120] The second contact portion 166 extending downward (in the positive direction of the Z axis) is connected to the lower end of the upper connection portion 167 on the opposite side of the held portion 163. The lower connection portion 164 is a portion connected to the lower end of the second contact portion 166 including a substantially U-shaped side surface. The first contact portion 165a bent by about 180 degrees is connected to the upper end of the inner connection portion 165 so as to protrude upward and toward the second contact portion 166.

[0121] The second terminal 161 is embedded in the second terminal receiving cavity 115 from the mounting surface 111b side which is the lower side (the surface in the positive direction of the Z axis) of the second base 111, and the held portion 163 is clamped from both sides by the side walls of the second terminal receiving outer cavity 115b formed on the inner side of the side wall portion 114, thereby fixing the second terminal 161 to the second base 111. In this state (i.e., in the state where the second terminal 161 is loaded in the second base 111), the first contact portion 165a and the second contact portion 166 are located on the left and right sides of the groove portion 112a and face each other. The second terminal 161 is an element formed integrally by processing a metal plate, and thus has a certain degree of elasticity. As can be clearly seen from the shape, the interval between the first contact portion 165a and the second contact portion 166 facing each other can be elastically changed. That is, when the first terminal 61 included in the first connector 1 is inserted between the first contact portion 165a and the second contact portion 166, the interval between the first contact portion 165a and the second contact portion 166 is elastically extended.

[0122] In addition, the second protruding end portions 121 are arranged at both ends of the second base 111 in the length direction as mating guide portions. The mating recess 122 is formed at each second protruding end portion 121 as a part of the recess 112. The mating recess 122 is a substantially rectangular recess and is connected to both ends of the length direction of each recess portion 112a. In addition, when the first connector 1 and the second connector 101 are mated, the first protruding end portion 21 provided in the first connector 1 is inserted into the mating recess 122.

[0123] The second protruding end portion 121 has a substantially U-shaped side wall when viewed from the mating direction, which defines three sides of the mating recess 122. A recessed island end recess 113a is formed at an end portion of the second convex portion 113 in the longitudinal direction.

[0124] The second reinforcing metal fitting 151 is attached to the second protruding end 121 as a reinforcing metal fitting attached to the second base 111. The second reinforcing fitting 151 is an integrally formed member by subjecting a metal plate to processing such as stamping and bending, and includes: an upper surface portion 152 covering at least a portion of the upper surface of the end wall portion of the second protruding end 121; an end surface portion 153 covering at least a portion of the end surface of the second protruding end 121 as the surface on the outer side in the length direction of the second base 111; a side surface portion 155 covering at least a portion of both side surfaces as the outer side in the width direction (Y-axis direction) of the second protruding end 121 of the second base 111; and a bottom surface covering portion 158 covering at least a portion of the bottom surface of the fitting recess 122. Note that the upper surface portion 152 includes a side connecting portion 152a and a front connecting portion 152b. The side surface portion 155 is connected to the end of the side connecting portion 152a, and the bottom surface covering portion 158 is connected to the end of the front connecting portion 152b. In addition, the contact piece 155a extending obliquely downward toward the bottom surface of the fitting recess 122 is connected to the upper end of the side portion 155, and the island end covering portion 158a is connected to the end of the bottom surface covering portion 158. The end of the island end covering portion 158a is inserted into the island end recess 113a. In addition, the vicinity of the lower end of the contact piece 155a is a portion that elastically contacts and conducts with the second side portion 55 of the first reinforcing fitting 51 when the first connector 1 and the second connector 101 are fitted.

[0125] The lower end of the side surface portion 155 is connected to a connection pad by welding or the like, and the connection pad is connected to a conductive trace of the second substrate. The conductive trace is typically a power line or a ground line. The lower end of the end surface portion 153 is also connected to a connection pad of the second substrate by welding or the like.

[0126] Next, the configuration of the aforementioned first reinforcing member 51 will be described in detail.

Fig.10a and Fig.10b middle, Fig.10a is the overall view and Fig.10b yes Fig.10a Enlarged view of section C in FIG.

[0128] In this embodiment, the upper portion 52 of the first reinforcing member 51 includes a front connecting piece 52a on each of the left and right sides of the front end (which is the inner end in the length direction of the first base 11). Figure 6c As shown in FIG. 1 , the front connecting piece 52a is a strip-shaped plate having a substantially crank shape when viewed from the up-down direction (fitting direction), and as shown in FIG. Figure 7b As shown, at its end is a front bent portion 52a1 bent about 90 degrees to face downward when viewed from the length direction of the first base 11. When the front connecting piece 52a is not formed, the upper end of the front bent portion 52a1 can be connected to the left and right sides near the front end of the upper surface portion 52 of the first reinforcing fitting 51.

[0129] In addition, the distal end (i.e., the end) of the front curved portion 52a1 is connected to the upper end of the first side portion 54 and extends toward the mounting surface 11b (i.e., in the downward direction). Figure 6aAs shown, the end (i.e., the lower end) of the first side portion 54 has a lower end bent portion 54a1, and when viewed from the length direction of the first base 11, the lower end bent portion 54a1 is bent approximately 90 degrees to face the outside in the width direction of the first base 11. In addition, the tail portion 54 extending to the outside in the width direction of the first base 11 is connected to the end of the lower end bent portion 54a1. The tail portion 54a is connected to a connection pad by welding or the like, and the connection pad is connected to a conductive trace of the first substrate. In addition, in the first side portion 54, a joining protrusion 54b is formed at the inner end (i.e., the front end) in the length direction of the first base 11. When the first side portion 54 is inserted into the first side recess 22b of the first base 11, the joining protrusion 54b engages with the front inner side wall 22b1 of the first side recess 22b, as shown in FIG. Fig.10a As shown, the first side surface portion 54 is thereby stably held in the first side surface recess 22 b.

[0130] In addition, the upper portion 52 is connected at the rear end (which is the outer end in the length direction of the first base 11) and includes a rear bent portion 52b, which is bent by about 90 degrees to face downward when viewed from the width direction of the first base 11, as shown in FIG. Figure 6b In addition, the upper end of the end surface portion 53 is connected to the end (ie, the lower end) of the rear curved portion 52b.

[0131] The end surface portion 53 includes a lower protrusion 53a connected to its lower end and protruding in the downward direction at the center in the width direction (Y-axis direction). The lower end of the lower protrusion 53a is connected to the connection pad of the first substrate by welding or the like. The end surface portion 53 includes a side connection piece 53b connected to both left and right side ends. The side connection piece 53b is a strip-shaped plate extending outward in the width direction and has a side bend 53b1 formed at its end. The side bend 53b1 is bent about 90 degrees to face forward, as shown in FIG. Figure 6c and Figure 6d shown.

[0132] In addition, the end (i.e., the front end) of the lateral curved portion 53b1 is connected to the outer end (i.e., the rear end) of the first base 11 in the longitudinal direction at the second side portion 55. The second side portion 55 includes a flat upper side portion 55a and a lower side portion 55b extending in the up-down direction and the front-back direction (i.e., in the XZ direction). Figure 6b As shown, the upper side portion 55a is formed to be wider than the lower side portion 55b, and specifically, the upper side portion 55a has a larger dimension in the front-to-back direction. Note that the rear end of the upper side portion 55a and the rear end of the lower side portion 55b are at the same position with respect to the length direction of the first base 11, and therefore, the front end of the upper side portion 55a is located closer to the inner side of the length direction of the first base 11 than the front end of the lower side portion 55b (i.e., in front).

[0133] The outer surface of the upper side portion 55a is a portion near the lower end of the contact piece 155a of the second reinforcing fitting 151 of the second connector 101. Figure 6b As shown, the upper side portion 55a is formed with a dimension in the front-to-back direction that is larger than the first side portion 54 and also larger than the lower side portion 55b. Therefore, even if a slight misalignment occurs when the first connector 1 and the second connector 101 are mated, contact with the vicinity of the lower end of the contact piece 155a of the second reinforcing fitting 151 can be reliably maintained. In addition, an engaging protrusion 55c is formed at the front end of the lower side portion 55b. When the second side portion 55 is inserted into the second side recess 22c of the first base 11, the engaging protrusion 55c engages with the front inner side wall 22c1 of the second side recess 22c, as shown in FIG. Fig.10a As shown, the second side surface portion 55 is thereby stably held in the second side surface recess 22c.

[0134] In addition, if Figure 9a As shown, the upper end of the upper side portion 55a is connected to the upper end bent portion 55d, the upper end bent portion 55d bends the end to face downward or obliquely downward, and the upper end of the auxiliary piece 55e extending downward or obliquely downward is connected to the end of the upper end bent portion 55d. Figures 7a to 9b In the drawings, for the convenience of illustration, only the example of the auxiliary piece 55e extending generally vertically downward rather than obliquely downward is drawn. In addition, the engaging protrusion 55f is formed on the front end of the auxiliary piece 55e. When a portion of the auxiliary piece 55e including at least the lower end is inserted into the recess 21b of the first base 11, the engaging protrusion 55f engages the front inner side wall of the recess 21b, whereby the auxiliary piece 55e is stably held in the recess 21b.

[0135] Note that the insertion recess 52c is formed as a recessed portion that is recessed toward the inner side in the width direction at both side edges in the width direction of the upper portion 52. In addition, at least a portion of the upper end vicinity of the second side portion 55, specifically the vicinity of the end of the upper end curved portion 55d and the auxiliary piece 55e, is inserted into the insertion recess 52c, and at least a portion including the lower end of the auxiliary piece 55e is inserted and held in the recess 21b. Note that the vicinity of the end of the upper end curved portion 55d and the auxiliary piece 55e do not contact the insertion recess 52c, and therefore, the second side portion 55 and the upper portion 52 do not contact.

[0136] Thus, by inserting at least a portion of the upper end vicinity of the second side surface portion 55 into the insertion recess 52c, the position of the top surface 55d1 of the upper end curved portion 55d (which is the upper end surface of the second side surface portion 55) can be accurately controlled. Specifically, the position of the top surface 55d1 with respect to the thickness direction (Z-axis direction) of the first base 11 can be controlled to be not higher than the position of the upper surface portion 52. In other words, as Figure 9aAs shown, the position of the top surface 55d1 can be controlled to be the same as or lower than the position of the upper surface 52 with respect to the thickness direction of the first base 11. If the position of the top surface 55d1 with respect to the thickness direction of the first base 11 is higher than the position of the upper surface 52, then during the fitting operation between the first connector 1 and the second connector 101, when the first connector 1 slides forward and backward or left and right (in the X-axis or Y-axis direction) relative to the second connector 101, the top surface 55d1 and its vicinity may catch the second reinforcing fitting 151 of the second connector 101 and the second side surface 55 may turn up. However, in the present embodiment, the vicinity of the end of the upper end bent portion 55d and the auxiliary piece 55e are inserted into the insertion recess 52c, and therefore, the position of the top surface 55d1 can be controlled not to be higher than the position of the upper surface 52. In addition, if the portion including at least the lower end of the auxiliary piece 55e is inserted and held in the recess 21b of the first base 11, the position of the top surface 55d1 can be more reliably controlled not to be higher than the position of the upper surface 52.

[0137] In addition, although the present embodiment describes the first reinforcing fitting 51 formed with the insertion recess 52c, the upper end bent portion 55d and the auxiliary piece 55e, the first reinforcing fitting 51 without these components may also be used. Specifically, the recessed portion of the insertion recess 52c has a plate as an upper surface, and the shape of the second side surface portion 55 does not have the upper end bent portion 55d and the auxiliary piece 55e. Even in this case, the upper end of the second side surface portion 55 can still be controlled to be not higher than the position of the upper surface portion 52.

[0138] Furthermore, in the first reinforcing accessory 51 of the present embodiment, the end face portion 53 is connected to the upper face portion 52 via a rear bent portion 52b, the first side portion 54 is connected to the upper face portion 52 via a front connecting piece 52a including a front bent portion 52a1, and the second side portion 55 is connected to the end face portion 53 via a side connecting piece 53b including a side bent portion 53b1. Generally speaking, in making accessories such as the first reinforcing accessory 51, a metal plate is stamped to form a generally flat element in which each portion is integrally connected, and then the generally flat element is bent to obtain a final three-dimensional shape. In the case of the aforementioned first reinforcing accessory 51, a metal plate is stamped to form a generally flat element in which portions corresponding to each portion including the upper face portion 52, the end face portion 53, the first side portion 54, and the second side portion 55 are integrally connected, and then the generally flat element is bent to form bent portions such as the rear bent portion 52b, the front bent portion 52a1, the side bent portion 53b1, and the like. Thus, a device having a shape such as the first reinforcing accessory 51 can be finally obtained. Figures 6a to 8bThe first reinforcing accessory 51 of the three-dimensionally shaped product shown in the figure. Thus, it can be subsequently seen that the first side surface portion 54 and the second side surface portion 55 of each of the side surfaces 21d covering both sides in the width direction of the first base 11 are portions obtained by independent bending, although these portions are close to each other in the first reinforcing accessory 51 of the final product.

[0139] Therefore, in the first reinforcing fitting 51 of the present embodiment, the position of the first side surface portion 54 and the position of the second side surface portion 55 can be independently and accurately controlled with respect to the width direction (Y-axis direction) of the first base 11. For example, the outer surface of the first side surface portion 54 and the outer surface of the second side surface portion 55 can be correctly flush with respect to the width direction of the first base 11. In addition, considering that the connection strength of the first reinforcing fitting 51 to the first substrate is more stable when the distance between the left and right tail portions 54a is wide, the position of the first side surface portion 54 can be further outside than the position of the second side surface portion 55 with respect to the width direction of the first base 11. In addition, with respect to the width direction of the first base 11, the position of the outer surface of the second side surface portion 55 can be strictly adjusted according to the position near the lower end of the contact piece 155a of the second reinforcing fitting 151 of the second connector 101 with which it contacts.

[0140] Furthermore, in the present embodiment, when the first reinforcing fitting 51 is connected to the first substrate by soldering, solder or flux does not adhere to the second side surface portion 55 near the lower end of the contact piece 155a contacting the second reinforcing fitting 151 due to the creeping of solder or flux. In the first reinforcing fitting 51, soldering is performed on the tail portion 54a connected to the lower end of the first side surface portion 54 and the lower end of the lower protruding portion 53a of the end surface portion 53. However, even if the first side surface portion 54 and the second side surface portion 55 on both sides in the width direction of the first base 11 are close to each other, solder or flux does not effectively reach the second side surface portion 55 because it is necessary to travel a long path from the tail portion 54a, through the first side surface portion 54, the front connection piece 52a, the upper surface portion 52, the end surface portion 53, the side connection piece 53b, etc. to reach the second side surface portion 55. In addition, the lower end solder or flux applied to the lower protrusion 53a of the end face portion 53 also needs to travel a long path (this long path passes along the end face portion 53 a distance in the width direction of approximately 1 / 2 of the width of the first connector 1 (this distance is much larger than the spacing of the first terminals 61) and further passes through the side connecting piece 53b), and therefore will not reach the second side portion 55.

[0141] Note that if it is necessary to more reliably prevent the solder or flux from being attached, an obstacle portion for preventing the solder or flux from climbing up may be formed near the lower end of the first side portion 54 and near the upper end of the lower protruding portion 53a. For example, when the first reinforcing fitting 51 is an element in which a nickel (Ni) plating layer is provided as a bottom plating layer on the surface of a metal plate and a gold (Au) plating layer is further applied to the side surfaces such as the front side, the rear side, etc. of the first side portion 54 including the tail portion 54a and the lower end bent portion 54a1 and to the side surfaces such as the front side, the rear side, etc. of the end face portion 53 including the lower protruding portion 53a, a laser beam is irradiated to melt the gold and expose the nickel on the surface in the portion irradiated by the laser beam to form an obstacle portion. If the obstacle is formed in the shape of a thin and long strip extending in the X-axis direction and the Y-axis direction on the side surfaces such as the front side and the rear side near the lower end of the first side surface portion 54 and on the side surfaces such as the front side and the rear side near the lower end or the upper end of the lower protruding portion 53a of the end surface portion 53, the solder or flux is prevented from climbing over the obstacle. Therefore, the solder or flux can be more reliably prevented from being attached to the second side surface portion 55.

[0142] Next, an operation of fitting the first connector 1 and the second connector 101 having the above-described configuration together will be described.

[0143] Here, the tail portion 62 of the first terminal 61 is connected to a connection pad connected to a conductive trace (not shown) of the first substrate by welding or the like, the tail portion 54a of the first side portion 54 of the first reinforcing fitting 51 is connected to a connection pad connected to a conductive trace of the first substrate by welding or the like, and the lower end of the lower protrusion 53a of the end face portion 53 is connected to a connection pad of the first substrate by welding or the like, so that the first connector 1 is surface mounted on the first substrate. Note that the conductive trace connected to the connection pad connected to the tail portion 62 of the first terminal 61 is a signal line, while the conductive trace connected to the connection pad connected to the tail portion 54a of the first side portion 54 of the first reinforcing fitting 51 is a power line. In addition, the connection pad connected to the lower end of the lower protrusion 53a of the end face portion 53 may or may not be connected to a power line.

[0144] Similarly, the tail portion 162 of the second terminal 161 is connected to a connection pad connected to a conductive trace (not shown) of the second substrate by welding or the like, the lower end of the side portion 155 of the second reinforcing fitting 151 is connected to a connection pad connected to a conductive trace of the second substrate by welding or the like, and the lower end of the end face portion 153 is connected to a connection pad of the second substrate by welding or the like, so that the second connector 101 is surface mounted on the second substrate. Note that the conductive trace connected to the connection pad connected to the tail portion 162 of the second terminal 161 is a signal line, while the conductive trace connected to the connection pad connected to the side portion 155 of the second reinforcing fitting 151 is a power line. In addition, the connection pad connected to the lower end of the end face portion 153 may or may not be connected to the power line.

[0145] First, if Figure 5 As shown, the operator sets the mating surface 11a of the first base 11 of the first connector 1 and the mating surface 111a of the second base 111 of the second connector 101 to face each other, and makes the position of the first protrusion 12 of the first connector 1 match the position of the corresponding groove 112a of the second connector 101. When the position of the first protruding end 21 of the first connector 1 matches the position of the corresponding mating recess 122 of the second connector 101, the positioning of the first connector 1 and the second connector 101 is completed.

[0146] In this state, when the first connector 1 and / or the second connector 101 moves in a direction approaching the opposite side (i.e., in the mating direction), the first convex portion 12 and the first protruding end portion 21 of the first connector 1 are inserted into the groove portion 112a and the mating recess 122 of the second connector 101. As a result, when the mating between the first connector 1 and the second connector 101 is completed, the first terminal 61 and the second terminal 161 enter a conducting state.

[0147] Incidentally, the first connector 1 and the second connector 101 are mounted on the first substrate and the second substrate having large areas, respectively. Therefore, the operator cannot see the fitting surface 11a of the first connector 1 and the fitting surface 111a of the second connector 101 and must perform the fitting operation by feeling. As a result, since correct alignment cannot be performed by feeling, the position of the first connector 1 and the position of the second connector 101 may be misaligned.

[0148] In this state, if the operator moves the first connector 1 and / or the second connector 101 in the mating direction, the first protruding end 21 of one side of the first connector 1 contacts the second protruding end 121 of one side of the second connector 101, and the first protruding end 21 receives the mating direction (i.e., in the mating direction) from the second protruding end 121. Figure 1 The pressure from top to bottom).

[0149] However, in the present embodiment, the first reinforcing fitting 51 is attached to the first protruding end portion 21, most of the upper surface 21a of the first protruding end portion 21 is covered by the upper surface portion 52 of the first reinforcing fitting 51, most of the end surface portion 21c of the first protruding end portion 21 is covered by the end surface portion 53 of the first reinforcing fitting 51, and most of the side surface 21d of the first protruding end portion 21 is covered by the first side surface portion 54 and the second side surface portion 55 of the first reinforcing fitting 51. Therefore, even if a large pressure is applied from the second protruding end portion 121, the pressure is transmitted from the first reinforcing fitting 51 to the first substrate. Thus, the pressure is hardly transmitted to the first protruding end portion 21. Therefore, the first protruding end portion 21 is not damaged or broken and can exhibit high strength.

[0150] Thus, in the present embodiment, the first connector 1 has a first base 11, a first terminal 61 attached to the first base 11, and a first reinforcing fitting 51 attached to the first base 11. In addition, the first base 11 includes first protruding end portions 21 formed at both ends in the length direction, and the first protruding end portions 21 are engaged with second protruding end portions 121 formed at both ends in the length direction of the second base 111 of the second connector 101. The first reinforcing fitting 51 includes an upper surface portion 52 covering at least a portion of an upper surface 21a of the first protruding end portion 21; an end surface portion 53 covering at least a portion of an end surface 21c of the first protruding end portion 21; a first side surface portion 54 covering at least a portion of each side surface 21d of the first protruding end portion 21; and a second side surface portion 55 covering at least a portion of each side surface 21d of the first protruding end portion 21. The end surface portion 53 is connected to the upper surface portion 52, the first side surface portion 54 is connected to the upper surface portion 52, and the second side surface portion 55 is located closer to the end surface 21c of the first protruding end portion 21 than the first side surface portion 54 and is connected to the end surface portion 53.

[0151] As a result, the first connector 1 can be provided with the first reinforcing fitting 51 which is small and low-profile, yet exhibits high strength and correct dimensional accuracy, and thereby has improved reliability.

[0152] Furthermore, the upper end of the end surface portion 53 is connected to the upper surface portion 52 via the rear curved portion 52b, the upper end of the first side surface portion 54 is connected to the upper surface portion 52 via the front curved portion 52a1, and the rear end of the second side surface portion 55 is connected to the end surface portion 53 via the lateral curved portion 53b1. Therefore, bending processing can be applied independently to the first side surface portion 54 and the second side surface portion 55, and thereby, the position of the first side surface portion 54 and the position of the second side surface portion 55 with respect to the width direction of the first base 11 can be independently and accurately controlled.

[0153] In addition, the upper surface portion 52 includes front connecting pieces 52a connected to the left and right sides of the front end thereof, the upper ends of the respective first side surface portions 54 are connected to the ends of the respective front connecting pieces 52a via the front curved portions 52a1 and extend in the vertical direction, the end surface portion 53 includes the side connecting pieces 53b connected to the left and right side ends, and the rear ends of the respective second side surface portions 55 are connected to the ends of the respective side connecting pieces 53b via the front curved portions 53b1 and extend in the vertical direction. As a result, the first side surface portion 54 and the second side surface portion 55 can be obtained by independent processing, and thus the positions of the first side surface portion 54 and the second side surface portion 55 can be easily controlled.

[0154] In addition, the upper surface 52 includes an insertion recess 52c formed at both side edges in the width direction thereof, and each second side surface 55 includes an upper end curved portion 55d connected to its upper end and an auxiliary piece 55e connected to the end of the upper end curved portion 55d and extending downward or obliquely downward, and the auxiliary piece 55e is inserted into the insertion recess 52c. Thus, the auxiliary piece 55e is inserted into the insertion recess 52c, and therefore, the position of the top surface 55d1 of the upper end curved portion 55d (which is the upper end surface of the second side surface 55) can be controlled not to be higher than the position of the upper surface 52.

[0155] Furthermore, the recess 21b is formed on the upper surface 21a of the first protruding end portion 21, and at least the lower end of the auxiliary piece 55e is inserted into the recess 21b. Therefore, the state in which the auxiliary piece 55e is inserted into the insertion recess 52c is stably maintained.

[0156] In addition, the tail portion 54a of the connection pad connected to the substrate is also connected to the lower end of the first side portion 54, the lower protrusion 53a of the connection pad connected to the substrate is connected to the lower end of the end portion 53, and an obstacle portion for preventing solder or flux from climbing up is formed on the side surfaces of the first side portion 54 and the end portion 53. Therefore, it is possible to reliably prevent solder or flux from adhering to the second side portion 55.

[0157] In addition, the gold plating layer is applied on the nickel base plating layer on the side surfaces of the first side surface portion 54 and the end surface portion 53, and the barrier portion is a portion where nickel is exposed on the surface. Therefore, the barrier portion that prevents solder or flux from climbing can be easily formed by irradiating a laser beam.
