The edge portion 63 is also formed to extend to the left and right side portions of the memory module 60, and a concave portion 62 having an arc shape is formed at an appropriate position on the left and right side portions. When the memory module 60 is mounted on the connector 1, the recess 62 has a function of engaging with an arc-shaped protruding piece 34 of the second side wall member 30 described later and positioning the memory module 60 at a predetermined position.

  The memory module connector 1 is attached to the housing 10 and the housing 10 in parallel to each other, and is attached to the plurality of contacts 11 corresponding to the external contacts 61 of the memory module 60 and the left side surface portion 13 and the right side surface portion 14 of the housing 10. The first side wall member 20, the second side wall member 30 that is disposed along the inner surface side of the first side wall member 20 and is fixed to the printed circuit board 50 via the soldering portion 37, and the first side wall member 20 and the first side wall member 20 A coupling member 40 capable of coupling the two side wall members 30 is included.

  The housing 10 is made of an insulating synthetic resin, has a substantially rectangular parallelepiped shape, and a plurality of contacts 11 are arranged in parallel and fixed toward the front (+ X direction in FIG. 1). A key engagement hole 15 corresponding to a reverse difference prevention key 64 provided in the memory module 60 is formed between the plurality of contacts 11. Further, the left side surface portion 13 and the right side surface portion 14 of the housing 10 are disposed along the first side wall member 20 for locking and fixing the memory module 60 and the inner surface side of the first side wall member. A second side wall member 30 fixed to the printed circuit board 50 via 37 is attached.

  The plurality of contacts 11 are fixed to grooves (not shown) formed in parallel in the housing 10. As shown in FIG. 9, the contact 11 has a contact portion 11 a that contacts the external contact 61 of the memory module 60 facing upward, and an elastic deformation portion 11 b that is formed in a substantially U shape following the contact portion. The fixing portion 11c that is press-fitted into the groove of the housing 10 and fixes the contact 11 in the housing 10, and the external contact of the circuit board 50 that is bent at a substantially right angle from the fixing portion 11c and extends downward (non- The terminal part 11d connected by soldering etc. is included. Since the contact 11 in this embodiment is configured as described above, the contact 11 can be attached from the front of the housing 10. The structure of the contact 11 is not limited to this. For example, the contact 11 may pass through the housing 10 in the front-rear direction, and the terminal portion 11d may be located behind the housing 10 (in the −X direction in FIG. 1). Good.

Subsequently, the first side wall member 20 will be described. The first side wall member 20 is a member whose one end is attached to the left and right side surfaces 13 and 14 of the housing 10 and whose free end can be opened to the left and right. The first side wall member 20 may be made of metal or may be made of a material such as a synthetic resin.
The first side wall member 20 is preferably formed by bending from a single plate by pressing or the like. As shown in FIG. 7, the first side wall member 20 includes a fixing portion 21 having press-fitting pieces 21 a and 21 b, an elastic deformation portion 22 extending in front of the fixing portion 21, and the vicinity of the tip of the elastic deformation portion 22. The latch claw 23 provided on the upper side thereof, the stopper 24 provided on the lower side of the elastically deforming portion 22, and the support frame 25 formed at the tip of the elastically deforming portion 22 are included.

In the present embodiment, the press-fitting pieces 21a and 21b of the fixing portion 21 are members formed in a substantially L shape from the upper side and the lower side of the fixing portion 21 and protruding upward (in the + Z direction in FIG. 1). It is formed by being bent at a right angle to. The press-fitting pieces 21a and 21b are press-fitted into mounting holes (not shown) provided on the front sides of the left and right side surface parts 13 and 14 of the housing 10 so as to correspond to the press-fitting pieces 21a and 21b. By press-fitting the press-fitting pieces 21 a and 21 b into the mounting holes, the fixing portion 21 comes into close contact with the side surface of the housing 10, whereby the first side wall member 20 is incorporated into the housing 10. Accordingly, the fixing portion 21 and the elastic deformation portion 22 subsequent thereto are incorporated into the housing 10 so as to form a substantially right angle with respect to the printed circuit board 50 when the housing 10 is attached to the printed circuit board 50.
In the present embodiment, the flat fixing portion 21 and the press-fitting pieces 21a and 21b are used to attach the first side wall member 20 to the housing 10, but the present invention is not limited to this. You may make it attach the flat fixing | fixed part without a press-fit piece directly to the housing side surface by adhesion | attachment or a fixing means like a screw | thread.
The elastic deformation portion 22 is a portion that extends forward of the fixing portion 21 following the fixing portion 21, and the end opposite to the fixing portion 21 is a free end, and thus the free end of the elastic deformation portion 22. Is configured to be able to open left and right (± Y direction in FIG. 1).

As described above, the latch claw 23 is provided in the vicinity of the tip of the elastic deformation portion 22 and on the upper side of the elastic deformation portion 22. In this embodiment, the latch claw 23 is formed by bending a member extending upward from the upper side of the elastic deformation portion 22 into an inverted U shape. The bent inner piece 23a of the latch claw 23 is formed to be inclined so as to slightly open upward, thereby facilitating the insertion of the memory module 60. The inner piece 23a also protrudes inward so that the distance between the tips of the inner pieces 23a, 23a of the latch claws 23, 23 provided on the left and right of the housing 10 is slightly smaller than the width W of the memory module. Is bent. With this configuration, once the memory module 60 gets over the latch claw 23 that protrudes inward and enters the lower side of the latch claw 23, the memory module 60 It cannot be removed from the connector 1.
In this embodiment, the latch claw 23 is formed by bending a member extending from the elastically deformable portion 22, but the present invention is not limited to this. For example, a member having an inclined surface or an inclined side opening upward may be formed on the member extending upward from the elastic deformation portion 22, and attached by fixing means such as adhesion or a screw.

  The stopper 24 is rearward (in the −X direction in FIG. 1) by a length slightly longer than the length of the second passage of the second side wall member 30 described later from the support frame 25 (FIGS. 5A and 5B). (See FIG. 1), and a member extending downward (−Z direction in FIG. 1) from the lower side of the elastically deformable portion 22 is formed by bending the members in two steps at substantially right angles. Therefore, the tip bent portion 24 a that is the second-stage bent portion of the stopper 24 is parallel to the elastic deformation portion 22. The horizontal bent portion 24b, which is the first bent portion of the stopper 24, is substantially perpendicular to the elastically deformable portion 22 and the tip bent portion 24a. The length of the horizontal bent portion 24 b regulates the amount of deformation of the elastic deformation portion 22. Therefore, the length of the horizontal bent portion 24b is larger than the protruding length of the latch claw 23 protruding inward.

  The support frame 24 is formed by bending a member extending downward from the lower end piece of the elastic deformation portion 22 in three steps at right angles. As a result, a first passage 28 having a rectangular cross section in which a coupling member 40 described later moves in the front-rear direction (± X direction) is formed. In the second bent portion of the support frame 25 parallel to the elastic deformation portion 22, an elastically deformable engagement claw 27 is cut and raised outward as shown in FIG. The window 26 is formed in the second-stage bent portion. The engaging claw 27 moves relative to the engaging member 40 in a groove 45 of the engaging member 40 described later.

Next, the second side wall member 30 will be described. The second side wall member 30 is disposed inside the first side wall member 20 described above, and one end thereof is fixed to the front surfaces of the left and right side surface portions 13 and 14 of the housing 10 and the other end is a printed circuit to which the connector 1 is attached. Fixed to the substrate 50. The second side wall member 30 may also be made of metal, or may be made of a material such as a synthetic resin. The second side wall member 30 is also preferably formed by bending from a single plate.
As shown in FIG. 8, the second side wall member 30 includes a fixing portion 31 having a press-fitting piece 31 a, a side wall portion 32 that forms a right angle with the fixing portion 31 at the lower side thereof, and a parallel with the fixing portion 31 at the upper side of the side wall portion 32. (I.e., perpendicular to the side wall portion 32), the support edge portion 33 is positioned above the fixed portion 31, and substantially parallel to the support edge portion 33 in the vicinity of the front end of the side wall portion (i.e., with respect to the side wall portion 32). And includes an arc-shaped protruding piece 34, an upper frame 35, a lower frame 36, and a soldering portion 37.

  The fixing portion 31 is incorporated into the housing 10 by press-fitting a press-fitting piece 31 a extending rearward into a mounting hole (not shown) provided in front of the housing 10. The fixing portion 31 is incorporated in the housing 10 so as to be parallel to the printed circuit board 50 when the housing 10 is attached to the printed circuit board 50.

  The side wall surface 32 is bent at a right angle upward with respect to the fixing portion 31 arranged in parallel to the printed circuit board 50 and extends forward of the fixing portion 31 as shown in FIG. When the second side wall member 30 is incorporated in the housing 10, the side wall surface 32 is usually formed so that the outer side surface of the side wall portion 32 is on the inner side surface of the elastic deformation portion 22 of the first side wall member 20 that is also incorporated in the housing 10. Arranged to touch.

  The support edge 33 is bent at a substantially right angle with respect to the side wall part 32 on the upper side of the side wall part 32, that is, parallel to the fixing part 31, and supports the edge part 63 extending to the left and right of the memory module 60.

  The arc-shaped protruding piece 34 is in front of the support edge 33, slightly above the support edge 33, parallel to the support edge 33, that is, substantially perpendicular to the side wall part 32, and on the upper side of the side wall part 32. It is bent. As described above, the arc-shaped projecting piece 34 engages with the arc-shaped recess 62 provided in the edge 63 extending to the left and right of the memory module 60, and positions the memory module 60 in the connector 1.

  The upper frame 35 and the lower frame 36 are bent in two steps from the upper side and the lower side of the side wall portion 32 at the tip of the side wall portion 32 to form a second passage 39 through which a terminal portion 44 of the coupling member 40 described later enters and exits. . The second passage 39 corresponds to the first passage 28 formed in the first side wall member 20 described above, and is disposed behind the first passage 28 so as to be continuous therewith. In the present embodiment, the second passage 39 is formed by the upper frame 35 and the lower frame 36. However, the present invention is not limited to this. For example, a side wall portion like the support frame 25 of the first side wall member 20 is used. It may be formed by bending a member extending downward from 32 in three stages.

  The soldering part 37 is located in front of the fixing part 31, is bent in three steps from the lower side of the side wall part 32, and extends inside the side wall part 32. As shown in FIG. 8, the soldering portion 37 is bent inward when the first step is bent, downward when the second step is bent, and again when the third step is bent. Each is folded to form a right angle. Therefore, the portion bent at the third level is parallel to the printed circuit board 50, and the bent portion at the third level is fixed to the printed circuit board 50 by means of soldering or the like. Accordingly, the soldering portion 37 functions as a board fixing member that fixes the second side wall member 30 to the printed circuit board 50.

Finally, the coupling member will be described. The coupling member 40 couples the first side wall member 20 and the second side wall member 30 described above, that is, locks the distal end of the elastic deformation portion 22 that is a free end of the first side wall member 20 to the second side wall member 30. And it is a member which makes it impossible for the elastic deformation part 22 front-end | tip of the 1st side wall member 20 to open to right and left. More specifically, the coupling member 40 is normally located in the first passage 28 formed by the support frame 25 of the first side wall member 20 and is in an unlocked state. When the coupling member 40 is locked, the end portion 44 of the coupling member 40 enters the second passage 39 formed by the upper frame 35 and the lower frame 36 of the second side wall member 30. The coupling member 40 is preferably made of synthetic resin, but is not limited thereto.
As shown in FIG. 6, the coupling member 40 includes a proximal end portion 41 and a distal end portion 44 as a coupling member main body, and a handle 42.
In the coupling member 40, an elongated groove 45 is formed on the inner surface side of the coupling member 40 over the base end portion 41 and the distal end portion of the coupling member main body. The groove 45 extends in the front-rear direction (± X direction in FIG. 1), a first locking recess 46 at the rear end thereof, and a second locking at a predetermined position in front of the first locking recess 46. A recess 47 is formed. The engagement claw 25 of the support frame 25 of the first side wall member 20 moves in the elongated groove 45, and the engagement claw 27 is fitted into the first locking recess 46 and the second locking recess 47. Thus, the movement of the coupling member 40 is restricted.
Further, a stepped portion 43 is formed on the outer surface side of the coupling member 40 between the proximal end portion 41 and the distal end portion 44. That is, the distal end portion 44 of the coupling member 40 is thinner than the proximal end portion 41 by the thickness of the side wall portion 32 of the second side wall member 30.
Moreover, it is preferable that the handle 42 is formed in the front end part of the base end part 41 toward the outer side. The handle 42 facilitates operation of the coupling member 40.

  The memory module connector 1 having the above-described configuration is fixed to the printed circuit board 50 via the terminal portion 11 d of the contact 11 and the soldering portion 37 of the second side wall portion 30. At this time, the 1st side wall member 20, the 2nd side wall member 30, and the coupling member 40 are arrange | positioned in the positional relationship as shown by Fig.5 (a).

  Next, an operation of attaching the memory module 60 to the memory module connector 1 mounted on the printed circuit board 50 and an operation of removing the memory module 60 from the connector 1 will be described.

  First, as shown in FIG. 3A, the memory module 60 is inclined from the front upper side of the connector 1 with its external contact 61 directed to the contact 11 of the connector 1 and the memory module 60 is tilted. As shown in FIG. 3B, the connector 1 is brought closer. At this time, as shown in FIG. 5A, the coupling member 40 has the engagement claw 27 of the first side wall member 20 engaged with the first locking recess 46 of the coupling member 40, and the base of the coupling member 40. Needless to say, the end portion 41 is in a non-locking state in which the end portion 41 protrudes forward (in the + X direction in FIG. 1) from the tip end portion (first passage 28) of the first side wall member 20.

  As shown in FIG. 3C, the external contact 61 of the memory module 60 is pressed against the corresponding contact 11 so that the reverse difference prevention key 64 of the memory module 60 is inserted into the key engagement hole 15 of the corresponding connector 1. Thereafter, the memory module 60 is rotated downward (counterclockwise in FIG. 3C) around the edge 63 where the external contact 61 is provided while maintaining this pressed state.

  When this rotating operation proceeds, as shown in FIG. 4A, the edge 63 extending to the left and right of the memory module 60 comes into contact with the inclined inner piece 23 a of the latch claw 23 of the first side wall member 20. . Further, as the rotation of the memory module 60 proceeds, the latch claw 23 of the first side wall member 20 is pushed outward (± Y direction in FIG. 1) by the edge 63 of the memory module 60, and thereby FIG. As shown in b), the elastic deformation portion 22 of the first side wall member 20 is deformed so as to open outward.

  When the rotation of the memory module 60 progresses and the edge 63 of the memory module 60 gets over the tip of the inner piece 23a of the latch claw 23 of the first side wall member 20, as shown in FIG. 4C, the first side wall member The elastic deformation portion 20 of 20 is automatically returned to the original position, that is, the position in contact with the side wall portion 32 of the second side wall member 30 by the elastic force. At this time, the arc-shaped recess 62 of the memory module 60 is engaged with the arc-shaped protruding piece 34 of the second side wall member 30. The memory module 60 is positioned by the engaging operation of the arc-shaped recess 62 of the memory module 60 and the arc-shaped protruding piece 34 of the second side wall member 30 and the pressing operation of the latch claw 23 of the first side wall member 20. Thereby, the external contact 61 of the memory module 60 and the contact portion 11a of the contact 11 maintain a state of being in electrical contact with a predetermined contact pressure.

  From the state of FIG. 4C, by pushing the coupling member 40 rearward (in the −X direction in FIG. 1), the end portion 44 of the coupling member 40 enters the second passage 39 of the second side wall member 30. Get in. The engagement of the engaging claw 27 of the first side wall member 20 with the second locking recess 47 of the coupling member 40 couples the first side wall member 20 and the second side wall member 30 (see FIG. 5B). ). Accordingly, since the second side wall member 30 is fixed to the printed circuit board 50, the first side wall member 20 also cannot move with respect to the printed circuit board 50, and accordingly, the elastic deformation portion 22 of the first side wall member 20. Is prevented from deforming outward. As a result, even if the connector 1 receives an impact or vibration while the memory module 60 is attached to the connector 1, the memory module 60 is prevented from being detached from the connector 1. In this way, the attachment of the memory module 60 to the connector 1 is completed.

  Next, in order to remove the memory module 60 from the connector 1, the grip 42 is grasped, and the engaging claw 27 is engaged with the first engaging member of the coupling member 40 in the state shown in FIG. 4 (d) or FIG. 5 (b). Pull it fully forward until it engages with the stop 46. In the state of FIG. 4C or FIG. 5A in which the coupling member 40 is pulled out, the elastically deforming portion 22 of the first side wall member 20 is in a deformable state. Thereafter, by opening the handle 42 or the base end portion 41 of the coupling member 40 to the outside, the elastic deformation portion 22 of the first side wall member 20 is also opened to the outside, and the latch claw 32 of the first side wall member 20 is Depart from part 63. At this time, since the coupling member 40 protrudes forward from the first side wall member 20 and the length of the first side wall member 20 is substantially extended, in order to open the first side wall member 20 outward, Less force is required than when only one side wall member 20 is opened. As described above, when the memory module 60 is pulled up with the first side wall member 20 opened, the memory module can be easily removed by pulling it upward and diagonally forward of the connector 1.
