  In the figure, reference numeral 1 denotes a connector according to the present embodiment, which is a first connector as one of a pair of board-to-board connectors which is a connector assembly (connector assembly). The first connector 1 is a surface mount type connector that is mounted on the surface of a first substrate, which is a substrate (not shown) as a mounting member, and is fitted to a second connector 101 as a counterpart connector. The second connector 101 is the other of the pair of board-to-board connectors, and is a surface-mounting connector that is mounted on the surface of a second board that is a board (not shown) as a mounting member.

  The first connector 1 and the second connector 101 in the present embodiment are preferably used for electrically connecting the first substrate and the second substrate as substrates, but other members. Can also be used for electrical connection. The first substrate and the second substrate are, for example, a printed circuit board, a flexible flat cable (FFC), a flexible circuit board (FPC), or the like used for an electronic device or the like, but may be any kind of substrate. .

  Further, in the present embodiment, expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the first connector 1 and the second connector 101 are as follows. It is not absolute but relative, and is appropriate when each part of the first connector 1 and the second connector 101 has the posture shown in the figure. It should be interpreted according to changes.

  And the said 1st connector 1 has the 1st housing 11 as a connector main body integrally formed with insulating materials, such as a synthetic resin. As shown in the figure, the first housing 11 has a substantially rectangular thick plate shape that is a substantially rectangular parallelepiped, and is on the side where the second connector 101 is inserted, that is, on the fitting surface 11a side (Z-axis positive side). The first concave portion 12 that is a substantially rectangular concave portion that is surrounded by the first concave portion 12 that fits with the second housing 111 of the second connector 101 is formed on the direction side. In the first recess 12, a first convex portion 13 is formed integrally with the first housing 11 as a middle island that fits into the concave groove portion 113 of the second connector 101. Further, the first convex portion 13 First side wall portions 14 that extend in parallel with the first convex portion 13 and that define both sides of the first concave portion 12 are first on both sides (Y axis positive direction side and negative direction side). It is formed integrally with the housing 11.

  In this case, the first convex portion 13 and the first side wall portion 14 protrude upward (Z-axis positive direction) from the bottom plate 18 that defines the bottom surface of the first concave portion 12, and the longitudinal direction (X Axial direction). Thus, on both sides of the first convex portion 13, concave groove portions 12 a that are elongated concave portions extending in the longitudinal direction of the first housing 11 are formed as a part of the first concave portion 12.

  Here, a first terminal accommodating cavity 15 is formed from the side surfaces on both sides of the first convex portion 13 to the bottom surface of the concave groove portion 12a. In the example shown in the figure, the first terminal accommodating cavity 15 is formed so as to penetrate the bottom plate 18 in the plate thickness direction (Z-axis direction). In the first terminal accommodating cavity 15, the groove-shaped portions formed on the side surfaces on both sides of the first convex portion 13 are referred to as first terminal accommodating inner cavities 15a.

  In the present embodiment, a plurality of first terminal receiving cavities 15 are formed at predetermined pitches on both sides of the first convex portion 13 so as to form two rows side by side in the longitudinal direction of the first housing 11. For example, 8 pieces are formed. The pitch and number of the first terminal accommodating cavities 15 can be changed as appropriate. A plurality of first terminals 61 as terminals that are accommodated in each of the first terminal accommodating cavities 15 and loaded into the first housing 11 are also arranged on both sides of the first convex portion 13 at a similar pitch. ing.

  The first terminal 61 is integrated with the first housing 11 by overmolding or insert molding. That is, the first housing 11 is molded by filling an insulating material such as a synthetic resin into a mold cavity in which the first terminals 61 are set in advance. Accordingly, the first terminal 61 is integrally attached to the first housing 11 so that at least the first held portion 63 is buried in the first housing 11. The first terminal 61 is not necessarily integrated with the first housing 11 by overmolding or insert molding, but may be attached to the first housing 11 by press fitting or the like, but here, for convenience of explanation, The case where it is integrated with the first housing 11 by overmolding or insert molding will be described.

  The first held portion 63 is a member extending in the left-right direction (Y-axis direction), that is, the width direction of the first housing 11 as a whole, but bulges upward (Z-axis positive direction). So that it is buried and held in the first side wall portion 14. The first tail portion 62 extends from one end of the first held portion 63 in the left-right direction, more specifically, outward in the width direction of the first housing 11, and conducts the first substrate. The connection pads connected to the traces are connected by soldering or the like. The conductive trace is typically a signal line. Further, the first connection portion 64 extends from one end of the first held portion 63 in the left-right direction, more specifically, inward in the width direction of the first housing 11. Further, the first contact arm portion 65 extends upward from the tip end of the first connection portion 64, and the vicinity of the upper end thereof is bent by about 180 degrees so as to form a U-shape, and the width of the first housing 11. A first contact portion 65a that bulges outward in the direction is formed.

  In the first terminal 61, at least most of the first held portion 63 is buried in the first side wall portion 14, and at least most of the first connection portion 64 and the first contact arm portion 65 are the first terminal accommodating cavity. 15 is fixed to the first housing 11 while being accommodated in the first housing 11. In this state, that is, in a state where the first terminal 61 is loaded in the first housing 11, the first contact portion 65 a faces outward in the width direction of the first housing 11, and the first protrusion 13 forms the first It is exposed on the side surface facing the side wall portion 14. Specifically, at least a part of the first contact portion 65a protrudes from the first terminal housing inner cavity 15a into the concave groove portion 12a.

  In addition, since the 1st terminal 61 is a member integrally formed by processing a metal plate, it has a certain amount of elasticity. As is apparent from the shape, the first connecting portion 64, the first contact arm portion 65, and the first contact portion 65a can be elastically deformed. Accordingly, when the second side wall portion 112 of the second connector 101 having the second terminal 161 attached thereto is inserted into the concave groove portion 12a, the first contact portion 65a that contacts the second terminal 161 becomes the first housing 11. It is elastically displaced toward the inside in the width direction.

  Further, first projecting end portions 21 as fitting guide portions are respectively disposed at both longitudinal ends of the first housing 11. Each first protruding end 21 is formed with a fitting recess 22 as a part of the first recess 12.

Then, the second projecting end portion 122 of the second connector 101 is inserted into the fitting recess 22 in a state where the first connector 1 and the second connector 101 are fitted.

  Further, the first projecting end portion 21 includes a first side wall extension portion 21c serving as a fitting guide side wall portion extending in the longitudinal direction of the first housing 11 from both longitudinal ends of the first side wall portion 14, and a first housing. 11 and a first end wall portion 21b extending in the width direction and having both ends connected to the first side wall extension portion 21c. In each first projecting end portion 21, the first end wall portion 21 b and the first side wall extension portion 21 c connected to both ends thereof form a continuous substantially U-shaped side wall, and a substantially rectangular fitting recess 22. The three sides are defined. In the first end wall portion 21b, an outer end concave portion 23a is formed as a first central leg receiving portion which is recessed on the outer side surface, and an inner end concave portion 23b is formed on the inner side surface. Yes. Further, in the first side wall extension 21c, an outer recess 23c is formed as a first side plate accommodating portion that is recessed in the outer surface, and an inner recess 23d is formed as an inner plate accommodating portion that is recessed in the inner surface.

The outer end recess 23a is fixed. The lower end of the first center connection foot 52d protrudes downward and is connected to a connection pad connected to the ground trace of the first substrate by soldering or the like. Thereby, the 1st reinforcement metal fitting 51 becomes difficult to deform | transform and the 1st connector 1 is reinforced effectively. The end wall inner cover portion 52b protects the first end wall portion 21b from the collision of the fitting when the first connector 1 and the second connector 101 are fitted, and the second connector 101 includes the second end portion. Although it is a member which has a guide function which guides the 2nd protrusion end part 122 appropriately in the fitting recessed part 22, it can also be abbreviate | omitted suitably.

  The first lateral portion 53 extends in the longitudinal direction of the first housing 11 and covers a majority of the upper surface of the first sidewall extension 21c, and the first lateral upper surface portion 53a. A first side plate portion 54 extending downward from an outer end in the width direction of the first housing 11, a first side plate connecting foot portion 54 a extending downward from a lower end of the first side plate portion 54, and the first side plate 54. An engagement protrusion 54b formed on a side end of the first side plate portion 54, an inner plate portion 55 extending downward from an inner end in the width direction of the first housing 11 on the first side upper surface portion 53a, An inner plate connecting leg portion 55a extending downward from the lower end of the inner plate portion 55 and an engaging recess 55b as a fitting guide engaging portion formed in the inner plate portion 55 are included.

  In the state where the first reinforcing bracket 51 is attached to the first housing 11, the first side upper surface portion 53a covers a majority of the upper surface of the first side wall extension portion 21c, and the first side plate portion 54 The extension 21c is accommodated in the outer recess 23c, covers the side surface 23e of the outer recess 23c, and the engagement protrusion 54b engages with the side wall of the outer recess 23c, thereby being fixed in the outer recess 23c. The lower end of the connection leg 54a protrudes downward and is connected to the connection pad connected to the ground trace of the first substrate by soldering or the like. Thereby, the 1st reinforcement metal fitting 51 becomes difficult to deform | transform and the 1st connector 1 is reinforced effectively. The inner plate portion 55 is accommodated in the inner recess 23d of the first side wall extension 21c, and the inner plate connecting foot portion 55a passes through the bottom opening 18a, and its lower end protrudes downward to ground the first substrate. The connection pads connected to the traces are connected by soldering or the like. Thereby, the 1st reinforcement metal fitting 51 becomes difficult to deform | transform and the 1st connector 1 is reinforced effectively. The upper surface of the first sidewall extension 21c is flush with the upper surface 21a of the first end wall 21b, but is formed to be lower than the upper surface 14a of the first sidewall 14 and the first sidewall extension 21c. The upper surface of the first lateral upper surface portion 53a that covers the upper surface of the first side wall portion 14a is substantially flush with the upper surface 14a of the first side wall portion 14.

  Furthermore, the first central connection foot 52d, the first side plate connection foot 54a, and the inner plate connection foot 55a are not necessarily all connected to the connection pads of the first board, and the circuit design of the first board The connection to any of the connection pads can be omitted depending on the above. Also, the bottom opening 18a and the inner plate connecting leg 55a passing through the bottom opening 18a can be omitted as appropriate.

  The shield plate portion 56 and the first support portion 57 as the first connecting portion are separated from each other in the width direction of the first housing 11, and a first side wall accommodating space 58 is formed therebetween. The shield plate portion 56 is an elongated flat belt-like plate extending in the thickness direction (Z-axis direction) and the longitudinal direction of the first housing 11, and both ends thereof are connected to the first side plate portion 54, It is substantially flush with the first side plate portion 54. The dimension of the shield plate part 56 in the thickness direction of the first housing 11 is substantially the same as the thickness of the first housing 11. The first support portion 57 is an elongated flat belt-like plate extending in the thickness direction and the longitudinal direction of the first housing 11, and both ends thereof are connected to the inner plate portion 55. It is roughly the same. Further, a connection leg portion connected to the connection pad may be formed at the lower end of the shield plate portion 56 so that the shield plate portion 56 is connected to the connection pad. The dimension of the first support portion 57 in the thickness direction of the first housing 11 is set smaller than the shield plate portion 56.

  Further, a concave groove portion 57 a as a support engagement portion extending in the longitudinal direction of the first housing 11 is formed on the surface of the first support portion 57 facing inward in the width direction of the first housing 11. . The support engagement portion is not necessarily a concave groove like the concave groove portion 57a, but may be a ridge, but here, a case where it is a concave groove like the concave groove portion 57a will be described. . Furthermore, in the example shown in FIGS. 2 and 3, the concave groove portion 57 a is formed continuously over the entire length of the first support portion 57, but the outline of the first support portion 57 is not necessarily required. It does not need to be formed over the entire length, and may be formed partially as shown in FIG. 4, or may not be necessarily formed continuously, but may be formed intermittently. However, here, for convenience of explanation, a case will be described in which the first support portion 57 is formed continuously over the entire length.

  In the state where the first reinforcing metal fitting 51 is attached to the first housing 11, the shield plate portion 56 covers the outer side in the width direction of the first housing 11 in the first side wall portion 14. However, since the side wall recess 14c that is recessed inwardly is formed on the outer side in the width direction of the first housing 11 in the first side wall part 14, the first side wall part 14 is more than the first side wall extension part 21c. In addition, the outer side surface 14d of the first side wall portion 14 is formed to be narrower than the first side wall accommodating space 58, and the width of the first housing 11 is larger than the side surface 23e of the outer concave portion 23c of the first side wall extension portion 21c. Located inside the direction. Therefore, the first side plate portion 54 covering the side surface 23e of the outer recessed portion 23c of the first side wall extension portion 21c and the shield plate portion 56 that are substantially flush with each other are separated from the outer side surface 14d of the first side wall portion 14, and the shield plate portion A lateral gap 58a is formed between the outer side surface 14d of the first side wall portion 14 and 56. In plan view (on the XY plane), the first tail portion 62 of the first terminal 61 protrudes outward from the outer surface 14 d of the first side wall portion 14 in the width direction of the first housing 11. However, it is located in the side gap 58 a and inside the shield plate portion 56. Accordingly, the entire first terminal 61 is located inside the shield plate portion 56 in the width direction of the first housing 11 and is isolated from the outside, so that the shielding performance of the first connector 1 is improved. To do. Furthermore, since the first side wall portion 14 holding the first terminal 61 is surrounded by the shield plate portion 56 and the first support portion 57 that are connected to each other, the shielding property of the first connector 1 is further increased. improves.

  In addition, the first support portion 57 covers the inner side surface 14 b of the first side wall portion 14 in a state where the first reinforcing metal fitting 51 is attached to the first housing 11. The surface of the first support portion 57 facing outward in the width direction of the first housing 11 is in contact with or close to the inner side surface 14b of the first side wall portion 14, so that the first housing of the first support portion 57 is in contact. 11 is a part of the side surface facing the first convex portion 13 in the concave groove portion 12a. Therefore, since the first side wall portion 14 is reinforced by the first support portion 57, the first side wall portion 14 is not deformed even if the dimension in the width direction of the first housing 11 is small, that is, thin. Further, since the first support portion 57 is formed with the concave groove portion 57a, the first side wall portion 14 is more effectively reinforced because the section modulus is large and the strength is high.

  Next, the configuration of the second connector 101 will be described.

  The second connector 101 as a counterpart connector in the present embodiment has a second housing 111 as a counterpart connector body integrally formed of an insulating material such as a synthetic resin.

The second housing 111 extends in the longitudinal direction (X-axis direction) of the second housing 111 on the side fitted into the first connector 1, that is, on the fitting surface 111 a side (Z-axis negative direction side). The elongated concave groove portion 113 and the second side wall portion 112 that is an elongated convex portion that defines the outer side of the concave groove portion 113 and extends in the longitudinal direction of the second housing 111 are integrally formed. The second side wall 112 is formed along both sides of the recessed groove 113 and along both sides of the second housing 111. Each second side wall 112 is provided with a second terminal 161 as a counterpart terminal. The second terminals 161 are arranged at a pitch corresponding to the first terminals 61 and in a corresponding number. The concave groove 113 is closed on the side mounted on the second substrate, that is, on the mounting surface side (Z-axis positive direction side) by the bottom plate 111b.

  The second terminal 161 is a member integrally formed by punching and bending a conductive metal plate, and is connected to the second connection portion 165 and the second connection portion 165.

The engaging convex portion 155b is a member that engages with an engaging concave portion 55b formed in the inner plate portion 55 of the first reinforcing bracket 51 when the first connector 1 and the second connector 101 are fitted. As long as it can be engaged with the engaging recess 55b, it may have any shape and does not necessarily have to be a protrusion. Further, the engaging convex portion 155b may be replaced with an engaging concave portion, and the engaging concave portion 55b formed on the inner plate portion 55 of the first reinforcing metal fitting 51 may be replaced with an engaging convex portion.

  In the state where the second reinforcing metal fitting 151 is attached to the second housing 111, the second side upper surface portion 153a covers a majority of the upper surface of the second side wall extension portion 122c, and the second side plate portion 155 The extension portion 122c is accommodated in the outer recess portion 123c, covers the side surface 123e of the outer recess portion 123c, and the engagement protrusion 155c engages with the side wall of the outer recess portion 123c, thereby being fixed in the outer recess portion 123c. The connection leg 155a extends outward from the lower end of the second side plate 155 and is connected to a connection pad connected to the ground trace of the second substrate by soldering or the like. Thereby, the 2nd reinforcement metal fitting 151 becomes difficult to deform | transform and the 2nd connector 101 is reinforced effectively. The upper surface of the second sidewall extension 122c is flush with the upper surface 122a of the second end wall 122b, but is formed to be lower than the upper surface 112a of the second sidewall 112, and the second sidewall extension 122c. The upper surface of the second lateral upper surface portion 153a that covers the upper surface of the second side wall portion 153a is substantially flush with the upper surface 112a of the second sidewall portion 112.

  The second support portion 157 as the counterpart support portion is an elongated flat belt-like plate extending in the thickness direction (Z-axis direction) and the longitudinal direction of the second housing 111, and both ends thereof are connected to the second side plate portion 155. It is connected and is approximately flush with the second side plate portion 155.

The counterpart support engagement portion does not necessarily have to be a protrusion like the protrusion 157a, and may be a concave groove, but here, it is assumed that it is a protrusion like the protrusion 157a. explain. Further, in the example shown in the figure, the protrusion 157a is formed continuously over the entire length of the second support portion 157, but is not necessarily the same as the entire length of the second support portion 157. It does not need to be formed over the entire surface, and may be partially formed in accordance with the recessed groove portion 57a formed in the first support portion 57 of the first reinforcing bracket 51, or may be formed continuously. Although it is not necessary and may be formed intermittently, here, for convenience of explanation, the case where the second support portion 157 is formed continuously over the entire length will be described.

  In a state where the second reinforcing metal fitting 151 is attached to the second housing 111, the second support portion 157 covers the outer side surface 112 d of the second side wall portion 112. A surface of the second support portion 157 facing inward in the width direction of the second housing 111 is in contact with or close to the outer surface 112 d of the second side wall portion 112. Therefore, since the second side wall portion 112 is reinforced by the second support portion 157, the second side wall portion 112 is not deformed even if the dimension in the width direction of the second housing 111 is small, that is, thin. In addition, since the second support portion 157 is formed with the protruding portion 157a, the second side wall portion 112 is more effectively reinforced because the section modulus is large and the strength is high.

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

  Here, the first connector 1 is connected by soldering or the like to the connection pad connected to the conductive trace of the first substrate (not shown) of the first tail portion 62 of the first terminal 61, By connecting the lower end of the central connection foot portion 52d, the lower end of the first side plate connection foot portion 54a, and the lower end of the inner plate connection foot portion 55a to the connection pads connected to the conductive traces of the first substrate by soldering or the like, It is assumed that it is surface-mounted on the first substrate. The conductive trace connected to the connection pad to which the first tail portion 62 of the first terminal 61 is connected is a signal line, the lower end of the first central connection foot portion 52d of the first reinforcing bracket 51, the first It is assumed that the conductive trace connected to the connection pad to which the lower end of the first side plate connection foot portion 54a and the lower end of the inner plate connection foot portion 55a are connected is a ground line.

  Similarly, the second connector 101 is connected by soldering or the like to the connection pad connected to the conductive trace of the second substrate (not shown) of the second terminal 161 of the second terminal 161, and The lower end of the central connection foot 152c and the second side plate connection foot 155a are surface-mounted on the second substrate by being connected to the connection pads connected to the conductive traces of the second substrate by soldering or the like. To do. The conductive trace connected to the connection pad to which the second tail portion 162 of the second terminal 161 is connected is a signal line, and the lower end of the second central connection foot portion 152c of the second reinforcing bracket 151 and the second The conductive trace connected to the connection pad to which the two-side plate connection leg 155a is connected is assumed to be a ground line.

  First, the operator sets the fitting surface 11 a of the first housing 11 of the first connector 1 and the fitting surface 111 a of the second housing 111 of the second connector 101 to face each other, and the second side wall of the second connector 101. The position of the portion 112 matches the position of the corresponding recessed groove portion 12 a of the first connector 1, and the position of the second protruding end portion 122 of the second connector 101 matches the position of the corresponding fitting recess 22 of the first connector 1. Then, the alignment between the first connector 1 and the second connector 101 is completed.

  In this state, when the first connector 1 and / or the second connector 101 is moved in the direction approaching the other side, that is, in the fitting direction (Z-axis direction), the second side wall portion 112 and the second connector 101 of the second connector 101 are moved. The two protruding end portions 122 are inserted into the recessed groove portion 12 a and the fitting recessed portion 22 of the first connector 1. Thereby, as FIG.1 and FIG.7 shows, when the fitting of the 1st connector 1 and the 2nd connector 101 is completed, it will be in the state which the 1st terminal 61 and the 2nd terminal 161 will conduct | electrically_connect.

  Specifically, the first contact portion 65a of each first terminal 61 and the second contact portion 165a of the second terminal 161 are in contact with each other, and as a result, the first tail portion 62 of the first terminal 61 is connected. The conductive traces connected to the connection pads on the one substrate are electrically connected to the conductive traces connected to the connection pads on the second substrate to which the second tail portion 162 of the second terminal 161 is connected. Thereby, the first terminal 61 and the second terminal 161 corresponding to each other are in a so-called single contact state that contacts only at one place, and compared with a so-called multiple contact state in which contact is made at multiple places. Since an unintended stub or Divided Circuit is not formed in the transmission line of the signal from the first tail part 62 of the first terminal 61 to the second tail part 162 of the second terminal 161, the impedance of the transmission line Is stable. Therefore, even when the transmission line is used for high-frequency signal transmission, good SI (signal-to-interference) characteristics can be obtained.

  In addition, the second protruding end 122 is inserted into the fitting recess 22, and the inner plate portion 55 of the first reinforcing bracket 51 and the second side plate portion 155 of the second reinforcing bracket 151 come into contact with each other. As a result, the lower end of the first central connection foot portion 52d of the first reinforcing bracket 51, the lower end of the first side plate connection foot portion 54a, and the lower end of the inner plate connection foot portion 55a are connected to the connection pads on the first substrate. And the conductive trace connected to the connection pad on the second substrate to which the lower end of the second center connection foot 152c of the second reinforcing metal fitting 151 and the second side plate connection foot 155a are connected. . In addition, since the engaging recess 55b formed in the inner plate portion 55 of the first reinforcing bracket 51 and the engaging convex portion 155b formed in the second side plate portion 155 of the second reinforcing bracket 151 are engaged, The first reinforcing bracket 51 and the second reinforcing bracket 151 are locked, and the second projecting end 122 of the second connector 101 is prevented from being pulled out from the fitting recess 22 of the first connector 1. Release of the fitted state between the first connector 2 and the second connector 101 is prevented.

  Further, the second side wall portion 112 of the second connector 101 is inserted into the recessed groove portion 12a of the first connector 1, and the first support portion 57 of the first reinforcement bracket 51 and the second support portion 157 of the second reinforcement bracket 151 are provided. Come into contact with each other, and the groove portion 57a of the first support portion 57 and the protrusion 157a of the second support portion 157 are engaged. As described above, the first reinforcing bracket 51 and the second reinforcing bracket 151 are engaged with the engaging concave portion 55b and the engaging convex portion 155b located in the vicinity of both longitudinal ends of the first connector 1 and the second connector 101. Not only the engaging concave portion 55b and the engaging convex portion 155b, but located closer to the center in the longitudinal direction of the first connector 1 and the second connector 101, and a wide range in the longitudinal direction of the first connector 1 and the second connector 101. Since the recessed groove portion 57a and the protruding portion 157a that exist over the entire length engage with each other, the locked state is effectively maintained. Therefore, the engagement state between the first connector 1 and the second connector 101 is reliably prevented.

  Further, as shown in FIG. 7C, the concave shape of the cross section of the concave groove portion 57a is formed so as to draw a curve having a larger radius of curvature than the convex shape of the cross section of the ridge portion 157a. The protrusion 157a is stably inserted into the recessed groove 57a. Thereby, cancellation | release of the fitting state of the 1st connector 1 and the 2nd connector 101 is prevented more reliably. It should be noted that the cross-sectional shapes of the groove 57a and the protrusion 157a do not necessarily have to be curved, and may include a corner or a pointed portion.

  In addition, the concave groove portion 57 a and the protrusion 157 a that are engaged with each other are connected to the first contact portion 65 a of the first terminal 61 and the second contact of the second terminal 161 in the longitudinal direction of the first connector 1 and the second connector 101. The first terminal 61 has the first terminal 61 because the first terminal 61 is present at a location that is relatively close to the first contact portion 65a of the first terminal 61 and the second contact portion 165a of the second terminal 161 over the existence range of the portion 165a. The contact state of the first contact portion 65a and the second contact portion 165a of the second terminal 161 is stably maintained, and the impedances of all transmission lines are stabilized.

  Further, the first reinforcing bracket 51 and the second reinforcing bracket 151 are brought into contact with each other and are electrically connected to each other to be equipotential, so that the shield function can be stably exhibited, and the first connector 1 and the second connector 101 are connected to each other. It can be shielded effectively. Furthermore, in a state where the first connector 1 and the second connector 101 are fitted, the shield plate portion 56 covers the outer sides in the width direction of the first housing 11 and the second housing 111, so that the first connector 1 and the second connector The connector 101 is shielded very effectively.

  Further, in order to release the fitting between the first connector 1 and the second connector 101, the first connector 1 and / or the second connector 101 is moved away from the mating side, that is, in the anti-fitting direction. The engaging recess 55 b of the first reinforcing bracket 51 receives a force in the direction of being pulled out from the first housing 11 from the engaging convex portion 155 b of the second reinforcing bracket 151. However, the inner plate connection leg 55a extending from the lower end of the inner plate portion 55 in which the engagement recess 55b is formed is accommodated in the bottom opening 18a of the bottom plate 18, and the lower end thereof serves as a connection pad of the first substrate. Since it is connected, even if it receives a force in the direction of pulling out from the first housing 11, it does not rise. Further, the inner plate connecting foot 55a may be accommodated in the bottom opening 18a of the bottom plate 18 without being connected to the connection pad of the first substrate. In this case, the inner plate connecting foot 55a is disposed on the side wall of the bottom opening 18a. It is also possible to prevent the roll-up from coming into contact with each other, or by providing an engagement protrusion on the inner plate connecting leg 55a and locking it to the side wall of the bottom opening 18a. Thereby, the displacement of the direction which the 1st reinforcement metal fitting 51 pulls out from the 1st housing 11 is blocked | prevented, and the intensity | strength of the 1st reinforcement metal fitting 51 improves more.

Accordingly, the entire first terminal 61 is located inside the shield plate portion 56 in the width direction of the first housing 11 and is isolated from the outside, so that the shielding performance of the first connector 1 is improved. To do.

  Further, the first housing 11 includes a first convex portion 13 that is a first convex portion 13 in the first concave portion 12 and that fits into the concave groove portion 113 of the second housing 111. The first protrusion 13 includes a first contact portion 65 a exposed on the side surface facing the first side wall portion 14, and contacts the second terminal 161 of the second connector 101 only at one location. Therefore, the impedance of the transmission line is stable, and good SI characteristics can be obtained even when used for high-frequency signal transmission.
