[0089] C2 Second Connector DETAILED DESCRIPTION

[0090] An example of a connector assembly proposed by the present disclosure will be described. Figure 1 The X1 direction and the X2 direction shown are called the right and left directions respectively. Figure 1 The Y1 direction and the Y2 direction shown are called the front and rear directions respectively, and Figure 1 The Z1 direction and the Z2 direction shown are referred to as the upper side and the lower side, respectively. The X1-X2 direction is referred to as the left-right direction or the "direction along the axis Ax of the locking rod 70" described later. The left-right direction is the direction in which the terminals 11, 12, 51, and 52 described later are arranged. These directions are used to illustrate the relative positional relationship of the various parts of the connector but do not limit the posture of the connector when it is installed on other devices.

[0091] [summary]

[0092] like Figure 2 As shown, the connector assembly 1 includes a first connector C1 and a second connector C2. For example, the first connector C1 is a connector mounted on a circuit substrate (not shown). Figure 3 As shown, the first connector C1 may include a plurality of terminals 11, 12 arranged in the left-right direction, a frame 20 surrounding the terminals 11, 12, and a first base 30 located in the frame 20 and holding the terminals 11, 12. The first base 30 may be attached to the frame 20 (see Figure 4 The second connector C2 includes a plurality of terminals 51 and 52 arranged in the left-right direction (see Figure 6 ). For example, the second connector C2 is a connector provided at the ends of the plurality of cables 91, 92. The terminals 51, 52 may be connected to the ends of the plurality of cables 91, 92, respectively. The second connector C2 may include a second base 60 (see Figure 2 ) and a locking bar 70 attached to the second base 60 (see Figure 2 ). Different from the connector assembly 1, both the first connector C1 and the second connector C2 can be connectors arranged at the ends of the cable.

[0093] The first connector C1 and the second connector C2 can be connected and separated in the up-down direction. The frame 20 has a box shape that is open upward. Figure 1As shown, when the first connector C1 and the second connector C2 are connected (i.e., when the connectors C1 and C2 are in a locked state described later), the second connector C2 is placed in the frame 20 of the first connector C1. The change of the relative position of the second connector C2 with respect to the first connector C1 is limited by the frame 20. For example, the forward (or backward) tilting of the second connector C2 with respect to the first base 30 of the first connector C1 is limited by the frame 20. The function of the frame 20 will be described in detail later.

[0094] [Overview of the Second Connector]

[0095] like Figure 6 As shown, the second connector C2 may include a plurality of front terminals 51 arranged in the left-right direction and a plurality of rear terminals 52 arranged in the left-right direction. The front terminal 51 is connected to the end of the cable 91 and may extend downward from the end of the cable 91. The rear terminal 52 is connected to the end of the cable 92 and may extend downward from the end of the cable 92. The cable 91 may extend backward from the upper portion of the front terminal 51. The cable 91 may bend backward and upward and extend obliquely backward and upward from the rear side of the second connector C2. Like the cable 91, the cable 92 may extend backward from the upper portion of the rear terminal 52. The cable 92 may bend backward and upward and extend obliquely backward and upward from the rear side of the second connector C2.

[0096] Since the cables 91 and 92 extend obliquely upward from the second connector C2 as described above, when a plurality of connector assemblies 1 are arranged in the front-rear direction and mounted on a circuit board, the intervals between adjacent connector assemblies 1 can be reduced. That is, the arrangement density of the plurality of connector assemblies 1 can be increased. In addition, in the case where a space on the upper side of the second connector C2 is ensured, the movable range of the lock lever 70 described later can be increased by utilizing the space.

[0097] like Figure 6 As shown, the second base 60 accommodates the connection portion between the terminals 51, 52 and the cables 91, 92 (the upper portion of the terminals 51, 52). The second base 60 has a fitting recess 62a at the lower portion. The fitting recess 62a opens downward. When the first connector C1 and the second connector C2 are connected, the first base 30 is embedded in the fitting recess 62a (refer to Fig. 10B The lower portions of the terminals 51 and 52 are exposed in the fitting recess 62a and respectively contact the terminals 11 and 12 described later of the first connector C1.

[0098] like Figure 6As shown, the second base 60 may have: a base upper portion 61, which constitutes the upper portion of the second base 60 and covers the upper side of the terminals 51, 52; and a base lower portion 62, which constitutes the lower portion of the second base 60 and has a fitting recess 62a. In addition, the second base 60 may have a base rear portion (holding portion) 63 that constitutes the rear portion of the second base 60 and holds the cables 91, 92. The base rear portion 63 may be insert-molded together with the cables 91, 92. That is, in the molding step of the base rear portion 63, in a state where a portion of each of the cables 91, 92 is placed in the mold, the resin material of the base rear portion 63 may be injected into the mold to mold the base rear portion 63. With this configuration, the cables 91, 92 can be firmly held.

[0099] As described above, the cables 91, 92 are bent backward and upward and extend obliquely backward and upward from the base rear portion 63 of the second connector C2. The base rear portion 63 can maintain the bent portions of the cables 91, 92. The base rear portion 63 can fix the extending direction of the cables 91, 92 and increase the arrangement density of the plurality of connector assemblies 1.

[0100] [Overview of the First Connector]

[0101] like Figure 4 As shown, the first connector C1 may include: a plurality of front terminals 11 held by the first base 30 and arranged in the left-right direction; and a plurality of rear terminals 12 held by the first base 30 and arranged in the left-right direction. Figure 7 As shown, the respective terminals 11, 12 may have: attached portions 11a, 12a exposed on the lower side of the first base 30; and contact portions 11b, 12b extending upward from the attached portions 11a, 12a and held by the first base 30. When the first connector C1 is mounted on the circuit substrate, the attached portions 11a, 12a may be soldered to the conductor portions formed on the circuit substrate. When the first connector C1 and the second connector C2 are connected (when the two connectors are in a locked state described later), the terminals 51, 52 of the second connector C2 contact the contact portions 11b, 12b, respectively (refer to Fig. 10B The first base 30 may include an outer wall portion 31 surrounding the plurality of terminals 11 and 12 and a central portion 32 disposed between the front terminal 11 and the rear terminal 12 and holding the terminals 11 and 12. The terminals 11 and 12 may be exposed in the outer wall portion 31.

[0102] like Figure 2 As shown, the first connector C1 may include a frame 20. The frame 20 has a generally rectangular shape surrounding the second connector C2 in a plan view. The frame 20 may include: a front wall portion 24, which is arranged along the front side of the second base 60; a rear wall portion 23, which is arranged along the rear side of the second base 60; and left and right side wall portions 25, which are arranged along the two side surfaces of the second base 60.

[0103] The first base 30 can be disposed in the frame 20 and fixed to the frame 20. Figure 4 As shown, the frame 20 has a base fixing portion 21 extending from the lower edge of the side wall portion 25 to the inside of the frame 20. The base fixing portion 21 can be fixed to the end 31a (outer wall portion 31) in the left and right direction of the first base 30. For example, the base fixing portion 21 may have: a bottom 21a extending from the lower edge of the left and right side wall portions 25 to the inside of the frame 20; and a hook portion 21b extending upward from the bottom 21a. An opening is formed on each of the bottom 21a and the hook portion 21b, and the end 31a (outer wall portion 31) of the first base 30 is embedded in the opening. The hook portion 21b is stuck on the upper side of the first base 30 and limits the upward relative movement of the first base 30 (outer wall portion 31) relative to the frame 20. With this configuration, the movement of the first base 30 is limited by the frame 20, so that the first base 30 (more specifically, the terminals 51, 52) can be limited from separating from the circuit substrate. A groove may be formed at the end portion 31a of the first base 30. An upper portion of the hook portion 21b may be inserted into the groove.

[0104] The frame 20 may open downward (see Figure 7 ). When the connectors C1 and C2 are connected (when the connectors are in a locked state), the lower end of the second connector C2 can contact the circuit substrate on which the first connector C1 is mounted.

[0105] like Figure 3 As shown in FIG. 1 , the frame 20 may have a plurality of attached portions 22a and 22b at the lower edge. The attached portions 22a and 22b are portions that are soldered to the circuit substrate on which the first base 30 is mounted. Figure 7 As shown, for example, the frame body 20 may have an attached portion 22a bent forward from the lower edge of the front wall portion 24. For example, the frame body 20 may have an attached portion 22b bent backward from the lower edge of the rear wall portion 23. The attached portions 22a, 22b may be formed at the lower edges of the ends of the front wall portion 24 and the rear wall portion 23 in the left-right direction.

[0106] [Frame of the first connector]

[0107] The distance between the front wall 24 and the rear wall 23 of the frame 20 may correspond to the dimension of the second base 60 in the front-rear direction. Thus, the forward tilt of the second connector C2 relative to the first base 30 can be limited by the front wall 24 of the frame 20, and conversely, the backward tilt of the second connector C2 can be limited by the rear wall 23 of the frame 20.

[0108] like Figure 2As shown, the second base 60 has a positioning surface 62b on the front surface. The positioning surface 62b protrudes forward from the other parts of the front surface of the second base 60, and the distance between the positioning surface 62b and the front wall portion 24 of the frame 20 can be smaller than the distance between the other parts of the front surface of the second base 60 and the front wall portion 24 (refer to Figure 5 ). The forward tilt of the second connector C2 relative to the first base 30 can be limited by the collision between the front wall portion 24 of the frame 20 and the positioning surface 62b. For example, the distance between the positioning surface 62b and the front wall portion 24 of the frame 20 may be less than the thickness of the front wall portion 24 of the frame 20. The positioning surface 62b may be located at the end of the second base 60 in the left-right direction.

[0109] like Figure 5 As shown, the rear wall portion 23 of the frame 20 may have a positioning portion 23b. The distance between the positioning portion 23b and the rear face 61c of the second base 60 is smaller than the distance between the other parts of the rear wall portion 23 and the rear face 61c of the second base 60. As a result, the backward tilting of the second connector C2 relative to the first base 30 can be limited by the conflict between the positioning portion 23b of the frame 20 and the rear face 61c of the second base 60. For example, the distance between the positioning portion 23b of the frame 20 and the rear face 61c of the second base 60 may be smaller than the thickness of the frame 20.

[0110] The positioning portion 23b may be formed at a position offset to the left or right relative to the portion of the second base 60 that holds the cables 91 and 92 (the base rear portion 63 in the example of the second connector C2). For example, the positioning portion 23b may be located at the end of the rear wall portion 23 in the left-right direction.

[0111] The rear wall portion 23 of the frame body 20 may include a transverse extension portion 23a disposed between the left and right positioning portions 23b and along the base rear portion 63 of the second base 60. The transverse extension portion 23a extends from one positioning portion 23b to the other positioning portion 23b. The transverse extension portion 23a protrudes rearward relative to the left and right positioning portions 23b. The rear wall portion 23 may include an opening at the lower side of the transverse extension portion 23a (see Figure 3 ).

[0112] like Fig. 10B As shown in FIG. 1 , when the first connector C1 is connected to the second connector C2 (in the locked state of the two connectors), the upper portion of the front wall portion 24 of the frame 20 is located on the front side of the front surface of the upper portion (the base upper portion 61) of the second base 60. That is, the height of the front wall portion 24 of the frame 20 corresponds to the height of the second base 60. The rear wall portion 23 of the frame 20 (more specifically, refer to FIG. Figure 5The positioning portion 23b) is also located at the rear side of the upper portion (upper portion 61 of the base) of the second base 60. The height of the rear wall portion 23 of the frame 20 corresponds to the height of the second base 60. Similarly, the height of the side wall portion 25 of the frame 20 also corresponds to the height of the second base 60. Thus, most of the second base 60 is located inside the frame 20 in the up-down, front-back, and left-right directions, and the inclination of the second connector C2 relative to the first base 30 in the front-back and left-right directions can be effectively limited by the frame 20.

[0113] like Figure 6 As shown in FIG. 1 , the end portion of the cable 92 connected to the rear terminal 52 (the portion extending rearward from the rear terminal 52) is lower than the end portion of the cable 91 connected to the front terminal 51 (the portion extending rearward from the front terminal 51). This can increase the arrangement density of the cables 91 and 92. Fig. 10B As shown, when the first connector C1 is connected to the second connector C2 (in the locked state described later), the heights of the front wall portion 24 and the rear wall portion 23 of the frame 20 are higher than the position of the end portion of the cable 91 on the upper side (the portion extending backward from the front terminal 51). As a result, the inclination of the second connector C2 in the front-to-back direction relative to the first base 30 can be effectively limited by the frame 20. The arrangement of the terminals 51, 52 and the cables 91, 92 is not limited to the example of the connector assembly 1. For example, the number of columns of terminals arranged in the left-right direction may be one or more than three. In this case, the upper edge of the frame may be higher than the end of the cable (the portion extending backward from the terminal).

[0114] [Second connector lock lever]

[0115] like Figure 2 As shown, the second connector C2 includes a locking rod 70. The locking rod 70 can be in a locking position where the locking rod 70 engages the frame 20 (the locking rod 70 is in a locking position). Figure 1 The lock bar 70 is in the unlocked position where the engagement between the lock bar 70 and the frame 20 is released (the lock bar 70 is in the unlocked position where the engagement between the lock bar 70 and the frame 20 is released). Figure 2 The lock lever 70 can be moved between the locked position and the unlocked position about an axis Ax that intersects the connection direction of the first connector C1 and the second connector C2 (the direction in which the two connectors C1 and C2 approach each other in the vertical direction). More specifically, the lock lever 70 can be rotated about the axis Ax along the left-right direction. When the lock lever 70 is moved from the right side of the second connector C2 (refer to the FIG. 2 ), the lock lever 70 can be moved between the locked position and the unlocked position. Figure 8 ), the locked position is defined as being in a counterclockwise rotation direction with respect to the unlocked position about the axis Ax. The lock bar 70 in the locked position engages the first connector C1 to restrict the separation of the first connector C1 and the second connector C2. In the following description, the rotation direction from the unlocked position to the locked position is referred to as the "locking direction", and the rotation direction from the locked position to the unlocked position is referred to as the "unlocking direction".

[0116] like Figure 2 As shown, the lock lever 70 has side portions 71 disposed along the left and right sides of the second base 60. The rod attachment portion 62c located on the axis Ax mounts the side portion 71 on the side of the second base 60 to allow the side portion 71 to rotate around the axis Ax. The rod attachment portion 62c may be a portion integrally formed with the second base 60 or may be a screw. The lock lever 70 has a lateral extension portion 74 extending between the left and right sides 71. When the lock lever 70 is in the unlocked position (refer to Figure 2 ), the lateral extension portion 74 is located on the upper side of the second base 60. When the locking bar 70 is in the locked position (refer to Figure 1 ), the lateral extension portion 74 is located on the front side of the second base 60.

[0117] [Joining portion and joined portion]

[0118] like Figure 2 As shown, the lock bar 70 may have a first engaged portion 73 and a second engaged portion 72a on the side portion 71. The first connector C1 may include a first engaging portion 26a and a second engaging portion 27a. In the example of the first connector C1, the first engaging portion 26a and the second engaging portion 27a are formed on the side wall portion 25 of the frame body 20. As described above, because the engaged portions 73, 72a are formed on the side portion 71 instead of the lateral extension portion 74 and the engaging portions 26a, 27a are formed on the side wall portion 25 instead of the front wall portion 24, the size of the connector assembly 1 in the front-to-back direction can be made small.

[0119] like Figure 2 As shown, the second engaging portion 27a may be a portion of the edge of a hole, a recess or a notch formed in the side wall portion 25. The first engaging portion 26a may also be a portion of the edge of a hole, a recess or a notch formed in the side wall portion 25. In the example of the first connector C1 as an embodiment of the present disclosure, the hole 27 and the hole 26 are formed in the side wall portion 25. Hereinafter, the hole 27 is referred to as a "mating hole". The upper edge of the mating hole 27 is the second engaging portion 27a. The hole 26 is referred to as a "through hole". In the example of the first connector C1, a portion of the edge of the through hole 26 is the first engaging portion 26a. As described later, the through hole 26 has a through area 26e (refer to Figure 8 ) and a joining area 26f (refer to Figure 8 ). The upper side portion of the edge of the engaging region 26f serves as the first engaging portion 26a and restricts the upward movement of the first engaged portion 73.

[0120] When the locking lever 70 is in the locked position (refer to Figure 1), the first engaging portion 26a engages the first engaged portion 73 of the lock lever 70 to restrict the first connector C1 and the second connector C2 from being separated in the up-down direction. Figure 1 ), the first engaged portion 73 is located at the rear of the through hole 26 formed in the side wall portion 25 (refer to Figure 8 26f in the engaging area) and is located on the lower side of the first engaging portion 26a (the upper part of the rear edge of the through hole 26). Therefore, the first engaging portion 26a limits the movement of the first engaged portion 73 in the separation direction of the first connector C1 and the second connector C2. More specifically, the first engaging portion 26a limits the upward movement of the first engaged portion 73 (here, the separation direction is the direction in which the first connector C1 and the second connector C2 are separated from each other and is the downward direction for the connector C1 and the upward direction for the connector C2). In the following description, the lock rod 70 is in the locked position (refer to Figure 1 ) is referred to as a “locked state”. Here, the first engaging portion 26a and the first engaged portion 73 engaging with each other means that the first engaging portion 26a and the first engaged portion 73 are in a positional relationship where the first engaging portion 26a restricts the first engaged portion 73 from moving upward.

[0121] The lock lever 70 may be formed of a metal material. The lock lever 70 may be formed by sheet metal processing. The frame 20 may also be formed of a metal material. The frame 20 may also be formed by sheet metal processing. Different from the examples of the connectors C1 and C2, one or both of the lock lever 70 and the frame 20 may be made of resin.

[0122] like Figure 2 As shown in FIG. 1 , the first engaged portion 73 may be a portion bent in the left-right direction (in the direction of the axis Ax). That is, the first engaged portion 73 on the right side may be a portion bent to the right, and the first engaged portion 73 on the left side may be a portion bent to the left. The first engaged portion 73 may have an edge 73a (refer to FIG. 1 ) facing in the direction intersecting the axis Ax. Figure 8 ). The edge 73a is the edge of the plate made of the material of the locking rod 70. Fig. 10A As shown, when the lock rod 70 is in the locked position, the edge 73a faces obliquely upward. Hereinafter, the edge 73a is referred to as the "collision edge". The first engaging portion 26a (a portion of the edge passing through the hole 26) may be located above the conflict edge 73a. With the first engaged portion 73 formed in this shape, the strength of the first engaged portion 73 against the force that separates the second connector C2 from the first connector C1 can be increased. That is, deformation of the first engaged portion 73 can be prevented. When the lock rod 70 is in the locked position, the conflict edge 73a may contact the first engaging portion 26a.

[0123] In the example of the connectors C1, C2, in the locked state of the connectors C1, C2, the collision edge 73a of the first engaged portion 73 is oriented obliquely rearward and upward. As described above, the cables 91, 92 are also oriented obliquely rearward and upward from the second base 60. Therefore, in the locked state, the first engaged portion 73 has a high strength against a force pulling the cables 91, 92 in the direction in which the cables 91, 92 extend.

[0124] The shapes of the first engaging portion 26a and the first engaged portion 73 are not limited to the examples of the connectors C1 and C2. For example, contrary to the examples of the connectors C1 and C2, the first engaging portion 26a may be a portion that bends inward (toward the interior of the frame 20) in the left-right direction (along the direction of the axis Ax) to replace the first engaged portion 73. The locking rod 70 may have a portion that is located on the lower side of the first engaging portion 26a like the first engaged portion 73 and whose upward movement is restricted by the first engaging portion 26a. In this case, the first engaging portion 26a may have an edge that faces in a direction intersecting the axis Ax, and the edge may contact the first engaged portion 73 to restrict the upward movement of the first engaged portion 73.

[0125] like Figure 2 As shown, the lock bar 70 may have an elastic portion 72 on the side portion 71. The elastic portion 72 is capable of elastic deformation in the left-right direction. In the example of the connector assembly 1, the elastic portion 72 is capable of elastic deformation in the direction along the axis Ax. For example, the elastic portion 72 may have a plate shape extending in a direction intersecting the axis Ax. The second engaged portion 72a is formed on the elastic portion 72. Thus, the second engaged portion 72a can be displaced in the left-right direction (in the direction of the axis Ax) by the elastic deformation of the elastic portion 72.

[0126] like Fig. 10C As shown, in the locked state of the connectors C1 and C2, the elastic portion 72 is elastically deformed in the left-right direction, and the second engaged portion 72a is driven to the second engaging portion 27a of the contact frame 20. For example, compared with the free state of the elastic portion 72 (a state without external force), in the locked state of the connectors C1 and C2, the elastic portion 72 can be bent toward the inside of the frame 20. In the locked state of the connectors C1 and C2, the second engaged portion 72a can be pressed against the second engaging portion 27a by the elastic force generated by the deformation of the elastic portion 72. With this structure, the relative position of the connectors C1 and C2 can be effectively prevented from changing in the left-right direction. For example, the relative position of the connectors C1 and C2 can be prevented from changing in the left-right direction due to slight vibration.

[0127] The first engaged portion 73, the second engaged portion 72a, and the elastic portion 72 may be formed on each of the two side portions 71 (left and right side portions 71) located on opposite sides in the left-right direction. In addition, the first engaging portion 26a and the second engaging portion 27a may be formed on each of the two side wall portions 25 (left and right side wall portions 25) located on opposite sides in the left-right direction. With this configuration, in the locked state of the connectors C1 and C2, the second connector C2 is positioned at the center of the frame 20 of the first connector C1 in the left-right direction (in the direction of the axis Ax).

[0128] Note that the first engaged portion 73 described above is formed at a portion having a higher rigidity in the left-right direction than the elastic portion 72. Thus, in the left-right direction, displacement of the first engaged portion 73 is less likely to occur than displacement of the second engaged portion 72a. Therefore, when a force for separating the connectors C1 and C2 acts on the connectors C1 and C2, the engagement between the first engaged portion 73 and the first engaging portion 26a can function effectively. In the example of the first connector C1, the side portion 71 of the lock lever 70 has a portion 71b (see FIG. 1 ) extending from the lever attachment portion 62c toward the first engaged portion 73. Figure 8 ). The width W1 of the portion 71b ensures that displacement of the first engaged portion 73 in the left-right direction is less likely to occur than displacement of the second engaged portion 72a. The means for ensuring the rigidity of the portion 71b is not limited to the example shown here. For example, the portion 71b may be formed of a material different from that of the other portions, or a rib for ensuring the rigidity of the portion 71b may be formed on the portion 71b.

[0129] like Fig. 10C As shown in FIG. 1 , the second base 60 has a fitting portion 62g that fits into the gap between the end surface 31b (end surface in the left-right direction) of the first base 30 and the side wall portion 25. The thickness of the fitting portion 62g in the left-right direction can be set according to the distance between the side wall portion 25 and the end surface 31b. Accordingly, the side wall portion 25 also restricts the relative position change of the connectors C1 and C2 in the left-right direction.

[0130] It is noted that the elastic portion (elastic portion 72 in the connector assembly 1) that can be elastically deformed in the left-right direction may be formed on the frame 20 instead of the lock bar 70. In this case, the second engaging portion 27a may be formed on the elastic portion and can be displaced in the left-right direction. In this case, the hole, recess or notch into which the second engaging portion 27a is embedded may be formed on the side portion 71 of the lock bar 70.

[0131] like Fig. 10CAs shown, the second engaged portion 72a of the locking rod 70 may be a convex portion protruding in the left-right direction (in the direction of the axis Ax). In more detail, the second engaged portion 72a formed on the side portion 71 on the right may protrude to the right, while the second engaged portion 72a formed on the side portion 71 on the left may protrude to the left. The second engaging portion 27a of the frame 20 is located in the unlocking direction (from the locked position toward the unlocking position) relative to the second engaged portion 72a. When the connectors C1 and C2 are observed in the left-right direction (the direction intersecting with the axis Ax), the second engaged portion 72a overlaps with the second engaging portion 27a at least partially. As a result, the movement of the second engaged portion 72a in the unlocking direction is limited by the second engaging portion 27a, and the rotation of the locking rod 70 can be effectively prevented.

[0132] like Fig. 10A As shown, in the locked state of the connectors C1 and C2, the second engaging portion 27a and the second engaged portion 72a are located in front of the axis Ax. In the locked state of the connectors C1 and C2, the second engaging portion 27a of the frame 20 is located above the second engaged portion 72a.

[0133] The positions of the second engaging portion 27a and the second engaged portion 72a are not limited to the examples of the connectors C1 and C2. For example, in the locked state of the connectors C1 and C2, the second engaging portion 27a and the second engaged portion 72a may be located below the axis Ax. In this case, the second engaging portion 27a may be located in front of the second engaged portion 72a. In this case as well, the second engaging portion 27a can limit the movement of the second engaged portion 72a in the unlocking direction.

[0134] The structure of the second engaging portion 27a and the second engaged portion 72a is not limited to the examples of the connectors C1 and C2. For example, the second engaging portion 27a of the frame 20 may be a convex portion protruding toward the inside of the frame 20. On the other hand, the second engaged portion 72a of the lock rod 70 may be a hole, a recess or a notch into which the second engaging portion 27a as a convex portion is embedded. Also under this structure, the second engaging portion 27a of the frame 20 may be located in the unlocking direction relative to the second engaged portion 72a. This effectively prevents the lock rod 70 in the locked position from rotating toward the unlocking position.

[0135] like Fig. 10CAs shown, the second engaged portion 72a may have an inclined surface 72b. The inclined surface 72b may be located in the locking direction relative to the second engaging portion 27a (the edge of the mating hole 27) of the frame 20 (in the example of connectors C1 and C2, it may be located "below" the second engaging portion 27a). In the locked state of the connectors C1 and C2, the elastic portion 72 may be elastically deformed in the left-right direction (in the direction of the axis Ax). More specifically, the elastic portion 72 may bend toward the center in the left-right direction. The inclined surface 72b is pressed against the second engaging portion 27a by the elastic force of the elastic portion 72, and generates a force that presses the second engaged portion 72a in the locking direction. As a result, as shown in FIG. Fig. 10A As shown, in the locked state of the connectors C1 and C2, the first engaged portion 73 is pressed against the first engaging portion 26a to effectively inhibit the relative movement of the connectors C1 and C2 (eg, the upward movement of the second connector C2).

[0136] As described above, the edge 73a of the first engaged portion 73 (the edge of the plate material of the lock lever 70) contacts the first engaging portion 26a. On the other hand, in the second engaged portion 72a, the inclined surface 72b (the surface of the plate material of the lock lever 70) contacts the second engaging portion 27a.

[0137] like Fig.11A As shown, in the locked state of the connectors C1 and C2, in the left-right direction, the first engaged portion 73 exceeds the first engaging portion 26a by a first width W1. Specifically, the first engaged portion 73 exceeds the first width W1 of the inner surface of the side wall portion 25 of the frame body 20. Fig. 11B As shown, in the locked state of the connectors C1 and C2, in the left-right direction, the second engaged portion 72a exceeds the second engaging portion 27a by the second width W2. In detail, the second engaged portion 72a exceeds the second width W2 of the inner surface of the side wall portion 25 of the frame body 20. The first width W1 is greater than the second width W2. With this structure, the engagement of the first engaging portion 26a and the first engaged portion 73 can be more effectively prevented from being released unintentionally.

[0138] like Figure 8 As shown, the through hole 26 is formed in the side wall portion 25 of the frame body 20. The through hole 26 has a through area 26e extending in the connection direction of the connectors C1 and C2 and a bonding area 26f defined behind the through area 26e. Fig.9A As shown, when the second connector C2 of the lock bar 70 is in the unlocked position and is embedded in the frame 20, the first engaged portion 73 passes through the passing area 26e and collides with the lower edge 26g (stopper) of the passing area 26e. Fig.9A The state shown is called "intermediate stop state". Fig. 9BAs shown, in this intermediate stop state, the terminals 51 and 52 of the second connector C2 have not reached the terminals 11 and 12 of the first connector C1.

[0139] like Figure 4 As shown in FIG. 1 , the left and right side walls 25 of the frame 20 have guide portions 25b at the uppermost portion. The guide portions 25b extend upward and open outward in the left-right direction. Figure 5 As shown, when the lock lever 70 in the unlocked position is viewed from a top view, the second engaged portion 72a partially overlaps the guide portion 25b. Therefore, in the process of rotating the lock lever 70 toward the locked position, the second engaged portion 72a contacts the guide portion 25b and is guided toward the inside of the frame 20. The second connector C2 is pushed toward the center in the left-right direction (the center along the axis Ax direction).

[0140] When the lock lever 70 rotates from the unlock position toward the lock position, the first engaged portion 73 moves toward the engagement region 26f with the axis Ax as the center (see Figure 8 ), and the second engaged portion 72a moves toward the fitting hole 27 with the axis Ax as the center. When the lock rod 70 reaches the locked position, the first engaged portion 73 is in the engagement area 26f, and the second engaged portion 72a is in the fitting hole 27. At this time, Fig. 10B As shown, the terminals 51 , 52 of the second connector C2 contact the terminals 11 , 12 of the first connector C1 .

[0141] like Figure 8 As shown, the frame 20 has an interference portion 25a on the side wall portion 25. The interference portion 25a is located in the area where the second engaged portion 72a passes through when the lock rod 70 moves from the unlocking position to the locking position. In the example of the second connector C2, the interference portion 25a is defined above the fitting hole 27. The interference portion 25a and the engaging portions 27a, 26a are formed on each of the left and right side wall portions 25. In the process of the lock rod 70 moving toward the locking position in the intermediate stop state, the left and right second engaged portions 72a interfere with the interference portion 25a and move toward the fitting hole 27 while sliding on the inner surface of the interference portion 25a. In this process, the second connector C2 is guided to the center in the left-right direction (in the direction of the axis Ax).

[0142] The elastic portion 72 and the second engaged portion 72a rotate around the axis Ax in the frame 20. The length of the elastic portion 72 and the position and shape of the second engaged portion 72a can be formed so as not to interfere with the inner surface of the front wall portion 24 of the frame 20 during the rotation of the elastic portion 72 and the second engaged portion 72a. Figure 8 ) may be formed obliquely to avoid interference with the inner surface of the front wall portion 24.

[0143] like Fig.9A As shown in FIG. 1 , in the intermediate stop state, the front portion 73b of the first engaged portion 73 is located in front of the axis Ax of the lock rod 70. That is, the front portion 73b of the first engaged portion 73 is located in front of the vertical plane Pv passing through the axis Ax and along the connection direction of the connectors C1 and C2. Fig. 10A As shown, in the locked state of the connectors C1 and C2, the front portion (lower portion) 73b of the first engaged portion 73 is located behind the axis Ax. That is, the front portion (lower portion) 73b of the first engaged portion 73 is located behind the vertical plane Pv passing through the axis Ax and along the connection direction of the connectors C1 and C2. With this configuration, when the second connector C2 is pushed toward the first connector C1 in the intermediate stop state, a torque is generated in the lock lever 70, and the lock lever 70 can be prevented from rotating toward the engagement area 26f when it is not subjected to a rotation operation by the operator.

[0144] like Fig. 10A As shown, in the locked state of the connectors C1 and C2, the contact position between the first engaging portion 26a and the first engaged portion 73 and the contact position between the second engaging portion 27a and the second engaged portion 72a are located on the opposite side of the plane Pv passing through the axis Ax and along the connection direction of the connectors C1 and C2. Thus, when a force is applied to separate the second connector C2 from the first connector C1, a moment in the opposite direction is generated in the locking rod 70. That is, a clockwise moment is generated in the locking rod 70 due to the contact between the first engaging portion 26a and the first engaged portion 73. On the other hand, a counterclockwise moment is generated in the locking rod 70 due to the contact between the second engaging portion 27a and the second engaged portion 72a. Therefore, when a force is applied to separate the second connector C2 from the first connector C1, the locking rod 70 can be prevented from rotating toward the unlocked position.

[0145] exist Fig. 10A , the distance L3 is the distance from the contact position between the first engaging portion 26a and the first engaged portion 73 to the axis Ax. The distance L4 is the distance from the contact position between the second engaging portion 27a and the second engaged portion 72a to the axis Ax. In more detail, the distance L3 is the distance between the portion of the first engaged portion 73 that is farthest from the axis Ax and the axis Ax. The distance L4 is greater than the distance L3. In this positional relationship, when a force that separates the second connector C2 from the first connector C1 is applied, the torque caused by the contact between the second engaging portion 27a and the second engaged portion 72a becomes greater than the torque caused by the contact between the first engaging portion 26a and the first engaged portion 73. As a result, the lock bar 70 can be more reliably prevented from rotating toward the unlocked position.

[0146] like Fig. 10AAs shown, the second engaged portion 72a and the first engaged portion 73 are located at different heights. In the locked state of the connectors C1 and C2, the position of the second engaged portion 72a is lower than the position of the first engaged portion 73. In more detail, the position of the second engaged portion 72a is lower than the lower end of the first engaged portion 73. Under this positional relationship, it is easy to make the above-mentioned distance L4 greater than the distance L3 while preventing the size of the second connector C2 in the front-to-back direction from increasing. Because the position of the second engaged portion 72a is lower than the first engaged portion 73, it is easy to ensure the length of the elastic portion 72 of the locking rod 70 (the length in the connection direction of the connectors C1 and C2) while preventing the size of the second connector C2 in the front-to-back direction from increasing.

[0147] In the locked state of the connectors C1 and C2, the rear end portion 27c of the second engaging portion 27a is located behind the front edge 26h of the through hole 26 through which the first engaged portion 73 passes. This prevents the second connector C2 from increasing in size in the front-rear direction.

[0148] exist Fig. 10A , the distance L5 is the distance to the operated portion 74a of the laterally extending portion 74 formed on the locking rod 70. The distance L5 is also greater than the above-mentioned distance L4. Therefore, the operator can operate the locking rod 70 relatively easily. In the locked state of the connectors C1 and C2, the operated portion 74a is located above the front wall portion 24 of the frame 20. The operated portion 74a may be located behind the front surface of the front wall portion 24, or the front surface of the operated portion 74a and the front surface of the front wall portion 24 may be located in the same vertical plane. In this manner, the size of the connector assembly 1 in the front-to-back direction can be prevented from increasing.

[0149] [Movement of the lock lever]

[0150] like Figure 2 As shown, when the lock bar 70 is in the unlocked position, the lateral extension 74 of the lock bar 70 may be located on the upper side of the second base 60. The second base 60 may have a support platform 61a (see FIG. 61a ) on its upper surface for supporting the lateral extension 74 of the lock bar 70 in the unlocked position. Figure 1 ). This configuration of the lock lever 70 and the support table 61a is possible by extending the cables 91, 92 from the rear side of the second connector C2 rather than from the upper side of the second connector C2. In addition, limiting the unlocking position to the upper side of the second base 60 can fully ensure the movable range of the lock lever 70. In the connector assembly 1, the movable range of the lock lever 70 is about 90 degrees.

[0151] The support platform 61a is defined behind the axis Ax, and when the lock bar 70 is in the unlocked position, the lateral extension 74 is located behind the axis Ax. On the other hand, when the lock bar 70 is in the locked position, the lateral extension 74 is located on the front side of the second base 60 (refer to Figure 1 ).

[0152] like Figure 2 As shown, a convex engaging portion 61b is formed on the support platform 61a. On the other hand, the lateral extension portion 74 of the lock rod 70 may have an engaging portion 74b such as a hole into which the engaging portion 61b is embedded when the lock rod 70 is in the unlocked position. With this structure, the vibration of the lock rod 70 in the unlocked position in the left and right directions can be effectively prevented. In contrast to the examples of the connectors C1 and C2, a recess may be formed on the support platform 61a, and a convex portion serving as the engaging portion 74b may be formed on the lateral extension portion 74. Figure 1 As shown, the lateral extending portion 74 may further include an operated portion 74 a at the center in the direction along the axis Ax (left-right direction). The operated portion 74 a protrudes from the edge of the lateral extending portion 74 .

[0153] [Detailed shape of the lock lever]

[0154] like Figure 8 As shown, the length L1 of the elastic portion 72 is greater than the distance L2 from the axis Ax to the elastic portion 72. Here, the length L1 is the length of the elastically deformed portion. The distance L2 is the distance from the axis Ax to the edge of the elastic portion 72. With this structure, the amount of elastic deformation of the elastic portion 72 (the displacement of the second engaged portion 72a in the left-right direction) can be sufficiently ensured. Figure 8 As shown, the side portion 71 of the lock lever 70 has an attached portion 71a fixed to the second base 60 via the lever attachment portion 62c. A gap S1 is formed between the attached portion 71a and the elastic portion 72. In the example of the first connector C1, the length of the gap S1 is consistent with the length L1 of the elastic portion 72.

[0155] like Fig. 10A As shown, when the lock lever 70 is in the locked position, the elastic portion 72 extends in the connection direction of the connectors C1 and C2 (downward direction for the connector C2). With the lock lever 70 formed in this shape, the length of the elastic portion 72 can be ensured while reducing the size of the connectors C1 and C2 in the direction intersecting the connection direction of the connectors C1 and C2 and the direction along the axis Ax (front-rear direction in the example of the connector assembly 1).

[0156] like Fig. 10AAs shown, the second connector C2 holds the cables 91, 92 at the rear (the rear part of the base 63). In the locked state of the connectors C1, C2, the position of the first engaged portion 73 and the position of the second engaged portion 72a are separated in the front-to-back direction. In more detail, the first engaged portion 73 is located behind the axis Ax, and the second engaged portion 72a is located in front of the axis Ax. With this configuration, for example, when a force that lifts the cables 91, 92 and causes the second connector C2 to tilt forward acts on the cables 91, 92, the first engaged portion 73 and the first engaging portion 26a prevent the rear of the second connector C2 from being lifted by the force. On the other hand, when a force that lowers the cables 91, 92 and causes the second connector C2 to tilt backward acts on the cables 91, 92, the second engaged portion 72a and the second engaging portion 27a can prevent the front of the second connector C2 from being lifted by the force.

[0157] like Fig. 10A As shown in the figure, in the locked state of the connectors C1 and C2, the first engaged portion 73 and the base rear portion 63 holding the cables 91 and 92 are located behind the second engaged portion 72a and higher than the second engaged portion 72a. With this configuration, the distance between the base rear portion 63 and the first engaged portion 73 becomes shorter. As a result, when the cables 91 and 92 are pulled upward, the first connector C1 can be prevented from tilting forward or backward.

[0158] In the example of the connector assembly 1, in the locked state of the connectors C1, C2, the first engaged portion 73 contacts the first engaging portion 26a. The first engaged portion 73 is bent in the left-right direction and contacts the first engaging portion 26a at the collision edge 73a (the edge facing in the direction intersecting the left-right direction, more specifically, the edge facing obliquely upward). Therefore, compared with the second engaged portion 72a, the first engaged portion 73 has a high rigidity to resist the force to which the first engaged portion 73 and the second engaged portion 72a are subjected. As a result, when the cables 91, 92 are pulled upward, the first connector C1 can be more effectively prevented from tilting.

[0159] like Fig. 10A As shown, when the lock rod 70 is in the locked position, the position of the axis Ax of the lock rod 70 is lower than the position of the upper edge 25d of the frame 20 (specifically, the upper surface of the guide portion 25b) in the connection direction of the connectors C1 and C2 (upward direction for the connector C1). As a result, the movement (tilting) of the second connector C2 in the front-to-back direction can be effectively prevented by the frame 20. In addition, because the engaged portions 73 and 72a can be set at a position separated downward from the upper edge 25d of the frame 20, the strength of the portion that restricts the upward movement of the engaged portions 73 and 72a (the portion above the engaging portions 26a and 27a in the side wall portion 25) can be easily ensured. In the example of the connectors C1 and C2, the entire rod attachment portion 62c is lower than the upper edge 25d of the frame 20.

[0160] [Positional relationship between cables and other elements]

[0161] As described above, the frame 20 has the lateral extension portion 23a (see FIG. 23a ) extending along the rear side of the base rear portion 63 of the second base 60 that holds the cables 91 and 92. Fig. 10B ). The left and right side wall portions 25 are connected via the transverse extension portion 23a. The cables 91, 92 extend obliquely backward and upward from the rear portion 63 of the base through the upper edge 23f of the transverse extension portion 23a and the lock rod 70 in the unlocked position. In other words, the cables 91, 92 extend obliquely backward and upward from the rear portion 63 of the base through the upper edge 23f of the transverse extension portion 23a and the support platform 61a of the second base 60. With this structure, the arrangement density of multiple connector assemblies 1 in the front-to-back direction can be increased, the rigidity of the frame 20 can be ensured by the transverse extension portion 23a, and the movable range of the lock rod 70 can be ensured.

[0162] [Summarize]

[0163] As described above, the connector assembly 1 includes: a first connector C1, which includes a plurality of terminals 11, 12 arranged in the left-right direction and a frame 20 surrounding the plurality of terminals 11, 12; and a second connector C2, which includes a plurality of terminals 51, 52 arranged in the left-right direction, connected to the first connector C1 in the up-down direction, and arranged inside the frame 20. The second connector C2 includes a locking rod 70, which can move between a locking position where the second connector C2 engages the frame 20 and an unlocking position where the engagement between the second connector C2 and the frame 20 is released. The locking rod 70 has a first engaged portion 73 and a second engaged portion 72a. The frame 20 has a first engaging portion 26a and a second engaging portion 27a. In a locked state where the locking rod 70 is in the locked position, the first engaging portion 26a engages the first engaged portion 73 and restricts the first connector C1 and the second connector C2 from being separated in the up-down direction. The locking rod 70 has an elastic portion 72 that can be elastically deformed in the left-right direction. The elastic portion 72 has a second engaged portion 72a and is elastically deformed in the left-right direction in the locked state to bring the second engaged portion 72a into contact with the second engaging portion 27a. According to the connector assembly 1, the relative positions of the two connectors C1 and C2 can be prevented from changing in the left-right direction due to slight vibration of the device on which the connector assembly 1 is installed.

[0164] [Modifications]

[0165] Note that the connector assembly proposed by the present disclosure is not limited to the connector assembly 1 described so far.

[0166] In the connector assembly 1, the locking rod 70 can rotate around the axis Ax, and the position of the axis Ax is fixed. The movement of the locking rod 70 is not limited to this. For example, during the rotation of the locking rod 70, the rotation center of the locking rod 70 (the axis Ax in the second connector C2) can slide in a direction orthogonal to the axis Ax (for example, forward or backward). In yet another example, the locking rod 70 can move in parallel to the up-down direction and / or the front-back direction without rotating.
