[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, the same or equivalent parts are denoted by the same reference numerals. In the following embodiments, the terms "have," "include," or "contain" also mean "consist of" or "consist of."
[0011] Embodiment 1 First, a first embodiment of the present invention will be described. As shown in Fig. 1, an electrical connector 1 electrically connects a board 2, which serves as a circuit board, to a card 3, which is a plate-like connection object. The electrical connector 1 is mounted on a main surface 2a of the board 2 by soldering or the like. Electrodes 2b are formed on the main surface 2a, and the electrical connector 1 connects to the electrodes 2b.
[0012] 2(A) and 2(B), the connector cover 5 is a cover that covers the electrical connector 1. The electrical connector 1 and the connector cover 5 are components of a connector assembly 100, which will be described later.
[0013] In this embodiment, the electrical connector 1, connector cover 5, and connector assembly 100 will be described with reference to a three-axis Cartesian coordinate system consisting of the X-axis, Y-axis, and Z-axis. The plane along the main surface 2a of the substrate 2 is defined as the XY plane, and the normal direction to the main surface 2a is defined as the Z-axis direction. The card 3 is inserted into the electrical connector 1 along the +Y direction.
[0014] The card 3 is, for example, an M.2 (M.2) card. M.2 is a standard that defines the form factor and connection terminals of built-in expansion cards for computers. The card 3 has a main body with wide front and back surfaces 3a with rectangular outer edges, and an internal circuit (not shown) such as memory is formed in the main body. The card 3 has a contact portion 3b, which is an electrode connected to the internal circuit, formed at one end of the main body (the end in the +Y direction in Figure 1). The electrical connector 1 connects to the contact portion 3b, establishing electrical continuity between the electrode 2b of the board 2 and the contact portion 3b of the card 3.
[0015] As shown in Fig. 1, an array of contact points 3b is formed at the edge of card 3. In fact, as shown in Fig. 3, in card 3, contact points 3b are formed in a row at the edge of one wide surface 3a and at the edge of the other wide surface 3a on the back side thereof. As shown in Figs. 1 and 3, contact points 3b formed on the wide surface 3a facing the -Z direction are referred to as contact points 3ba, and contact points 3b formed on the wide surface 3a facing the +Z direction are referred to as contact points 3bb.
[0016] An array of contact portions 3ba and an array of contact portions 3bb are formed on card 3. The arrangement pitch of contact portions 3ba and the arrangement pitch of contact portions 3bb are the same, and the positions of contact portions 3ba are shifted by half the arrangement pitch in the arrangement direction (the X-axis direction in FIG. 1) from the positions of contact portions 3bb.
[0017] Correspondingly, an array of electrodes 2b is formed on the main surface 2a of the substrate 2, aligned in the X-axis direction, with the same number and arrangement pitch as the contact portions 3b of the card 3. The electrodes 2b are formed in two rows in the Y-axis direction on the card 3. Specifically, as shown in FIG. 3, an array of electrodes 2ba is formed as an array of electrodes 2b closer to the -Y direction corresponding to the arrangement of contact portions 3ba, and an array of electrodes 2bb is formed as an array of electrodes 2b closer to the +Y direction corresponding to the arrangement of contact portions 3bb. The arrangement pitch of the electrodes 2ba, 2bb in each row is the same as the contact portions 3ba, 3bb, and the positions of the electrodes 2b in the X-axis direction are shifted by half the arrangement pitch in the arrangement direction (X-axis direction) between rows.
[0018] The electrical connector 1 connects the electrodes 2b of the substrate 2 to the contact points 3b of the card 3 in a one-to-one relationship. A plurality of electrodes 2c are arranged on the main surface 2a so as to surround the arrangement of the electrodes 2b. The electrodes 2c are, for example, ground electrodes.
[0019] [Electrical Connector] The following describes the configuration of the electrical connector 1. As shown in Figure 1, the electrical connector 1 includes a housing 10 as a base, and contacts 11 as terminals that connect electrodes 2b of a board 2 and contact portions 3b of a card 3.
[0020] The housing 10 is made of an insulating material, such as resin. The housing 10 has a generally rectangular parallelepiped shape with the X-axis direction as the longitudinal direction. The housing 10 has a bottom surface F1 (see FIG. 3) facing the board 2, a top surface F2 on the opposite side, a front surface F3 facing the card 3 in FIG. 1, a back surface F4 (see FIG. 4) on the opposite side, and two side surfaces F5 on both ends in the longitudinal direction (X-axis direction).
[0021] The housing 10 is mounted on the substrate 2 so that the front face F3 faces the -Y direction. An insertion slot 10a is formed on the front face F3 of the housing 10, into which one end of the card 3, on which the contact portion 3b is formed, is inserted. As shown in FIGS. 1 and 3 , the card 3 is inserted into the insertion slot 10a with the wide surface 3a facing the main surface 2a of the substrate 2. Since the wide surface 3a facing the main surface 2a must be the wide surface 3a on which the contact portion 3ba is formed, a mechanism is provided to prevent the card 3 from being inserted into the insertion slot 10a by arranging the wide surface 3a on which the contact portion 3bb is formed facing the main surface 2a. A slit 3e is formed on one end of the card 3 on which the contact portion 3b is formed. The slit 3e is positioned offset from the center of the card 3 in the X-axis direction. A partition 10b is formed in the insertion slot 10a of the housing 10. The partition 10b is positioned to match the position of the slit 3e in the X-axis direction. Since the slit 3e is formed offset from the center of the card 3, if the card 3 is turned over, the position of the slit 3e and the position of the partition 10b will not match, and one end of the card 3 will abut against the partition 10b, making it impossible to insert the card 3 into the insertion slot 10a.
[0022] The contacts 11 are made of a conductive material, such as metal. Specifically, the contacts 11 are formed, for example, by stamping a metal plate. As shown in FIG. 3, the multiple contacts 11 include a locking portion 20, a board connection portion 21, and a contact portion 22. While the housing 10 is not shown in FIG. 3 for clarity, the locking portion 20 actually locks into the housing 10. This attaches the contacts 11 to the housing 10. The board connection portion 21 is connected to an electrode 2b of the board 2 by soldering or the like. The contact portion 22 contacts a contact portion 3b of the card 3 inserted into the insertion slot 10a. The contact portion 3b of the card 3 and the electrode 2b of the board 2 are electrically connected via the contacts 11.
[0023] The electrical connector 1 includes a plurality of contacts 11. The plurality of contacts 11 are arranged in the X-axis direction corresponding to the arrangement of the contact portions 3b of the card 3 and the arrangement of the electrodes 2b of the substrate 2. The arrangement of the contacts 11 in the X-axis direction is arranged in two rows side by side in the Y-axis direction. The number of contacts 11 in each row is the same as the number of contact portions 3ba, 3bb in the arrangement of the contact portions 3ba, 3bb of the card 3, the arrangement pitch is also the same as the arrangement of the contact portions 3ba, 3bb, and the positions of the contacts 11 in each row in the X-axis direction are shifted by half the arrangement pitch.
[0024] As shown in Figure 3, of the contacts 11, the contacts 11 in the row closer to the -Y direction are referred to as contacts 11a, and the contacts 11 in the row closer to the +Y direction are referred to as contacts 11b. Contact portion 22 of contact 11a comes into contact with contact portion 3ba of contact portions 3b of the card 3 inserted into insertion slot 10a, which is closer to the -Z direction. Similarly, contact portion 22 of contact 11b comes into contact with contact portion 3bb of contact portions 3b of the card 3 inserted into insertion slot 10a, which is closer to the +Z direction. This forms a transmission line from contact portion 3ba inserted into insertion slot 10a closer to the -Z direction → contact 11a → electrode 2ba, and a transmission line from contact portion 3bb inserted into insertion slot 10a closer to the +Z direction → contact 11b → electrode 2bb.
[0025] 1 and 3, a shield case 3c, which is an electromagnetic wave shield that covers an internal circuit (not shown) and prevents electromagnetic waves from entering from the outside, is provided on the surface of the card 3 on which the contact portion 3bb is arranged. The shield case 3c is made of a conductive material, for example, a metal.
[0026] 2(A) and 2(B), a semicircular notch 3d (described later) is provided at the other end of the card 3, and the card 3 is locked to the substrate 2 at the notch 3d with a bolt 7. This positions the card 3 approximately parallel to the main surface 2a of the substrate 2.
[0027] [Connector cover] 1 is covered with a connector cover 5 as shown in Figures 2(A), 2(B) and 3. The connector cover 5 includes a shell 30 and a pivotable cover 31.
[0028] [shell] The shell 30 is made of a conductive material, such as metal. For example, the shell 30 is made by bending a metal plate cut into a predetermined shape. The shell 30 covers the outer surface of the housing 10 except for the bottom surface F1 (see FIG. 3) and the front surface F3 (see FIG. 1) of the housing 10, and is connected to the substrate 2. The shell 30 may also cover a portion of both ends of the front surface F3.
[0029] 2(A), 2(B), and 4, the shell 30 includes a top plate S1 disposed opposite the top surface F2 of the housing 10, a side plate S2 continuous with the top plate S1 and disposed opposite the side surface F5 of the housing 10, and a back plate S3 continuous with the top plate S1 and disposed opposite the back surface F4 of the housing 10. The top plate S1 covers the top surface F2 of the housing 10. The side plate S2 covers the side surface F5 of the housing 10. The back plate S3 covers the back surface F4 of the housing 10.
[0030] The top plate S1, the side plate S2, and the back plate S3 are provided with substrate connection portions 30a that connect to the electrodes 2c of the substrate 2. By connecting the substrate connection portions 30a to the electrodes 2c, the electrodes 2c of the substrate 2 and the shell 30 are at the same potential. Since the electrode 2c is arranged to surround the electrode 2b, the substrate connection portions 30a of the shell 30 are also arranged to surround the electrode 2b and the contacts 11 connected to it along the XY plane.
[0031] The top plate S1, side plate S2, and rear plate S3 allow the shell 30 to function as an electromagnetic shield covering the top face F2, rear face F4, and side face F5 of the housing of the electrical connector 1. In particular, as shown in Figure 4, the top plate S1, side plate S2, and rear plate S3 are disposed opposite the rear face F4 of the housing 10 and cover the board connecting portions 21 of the contacts 11 extending from the rear face F4. This improves the degree of electromagnetic wave shielding between the contacts 11 extending from the rear face F4 of the housing 10 and the outside world.
[0032] [Rotating cover] 2(A) and 2(B), the rotating cover 31 is made of a conductive material, such as metal, and is formed by bending a metal plate cut into a predetermined shape, for example.
[0033] The pivotable cover 31 includes a cover body 31a. The cover body 31a is composed of a top panel C1 and two side panels C2 continuous with the top panel C1. One end of the top panel C1 of the cover body 31a, which faces the direction in which one end V3 of the card 3 is inserted into the insertion slot 10a, is designated V1, and the other end of the top panel C1 of the cover body 31a located opposite the one end V1 is designated W1. The other end of the top panel C1 of the cover body 31a located opposite the one end V3 of the card 3 is designated W3. As shown in FIG. 3, the top panel C1 is disposed so as to protrude in the -Y direction beyond the top panel S1 of the shell 30. That is, as shown in FIG. 2(B), when the cover body 31a is located at the second position P2, the other end W1 in the -Y direction of the cover body 31a is located between the contact portion 3b of the card 3 and the other end W3 of the card 3 (see FIG. 1; the end in the -Y direction not shown in FIG. 3). As a result, when the rotating cover 31 is in the second position P2, the upper surface plate C1 of the cover body 31a of the rotating cover 31 covers the contact portion 3b of the card 3.
[0034] The other end W2 of the side panel C2 of the cover main body 31a is located opposite to one end V2 of the side panel C2 of the cover main body 31a. The side panel C2 is disposed so as to protrude in the -Y direction beyond the side panel S2 of the shell 30. That is, as shown in FIG. 2(B), the other end (open end) W2 of the side panel C2 of the cover main body 31a is located between the contact portion 3b of the card 3 and the other end W3 of the card 3. As a result, when the rotating cover 31 is in the second position P2, the side panel C2 of the cover main body 31a of the rotating cover 31 covers the contact portion 3b of the card 3 as viewed in the X-axis direction.
[0035] The pivotable cover 31 is attached to the shell 30 so as to be pivotable between a first position P1 shown in Fig. 2(A) and a second position P2 shown in Fig. 2(B). As shown in Fig. 2(A), the pivotable cover 31 is spaced apart from the contact portions 3b of the card 3 at the first position P1. As shown in Fig. 2(B), the pivotable cover 31 faces the contact portions 3b at the second position P2. The cover main body 31a covers the contact portions 3b when the pivotable cover 31 is at least in the second position P2.
[0036] As shown in FIG. 5(A), shafts 30c are formed in the portion of each side panel S2 of the shell 30 closer to the +Y direction by cutting out a portion of a metal plate and protruding it outward in the X-axis direction. Also, as shown in FIG. 3, when the rotating cover 31 is located at the second position P2, it has arm portions 31b that protrude in the +Y direction from both ends in the X-axis direction, and the ends of the arm portions 31b are provided with through-holes serving as shafts 31c. As shown in FIG. 5(B), the shafts 30c of the shell 30 are fitted into the shafts 31c of the arm portions 31b of the rotating cover 31. This allows the rotating cover 31 to rotate between the first position P1 (see FIG. 2(A)) and the second position P2 (see FIG. 2(B)) around the shafts 30c, 31c as rotation axes.
[0037] As shown in Fig. 5(A), a convex mating portion 30d is provided on the side plate S2 of the shell 30. Meanwhile, as shown in Fig. 5(B), a through-hole or concave mating portion 31d is provided on the side plate S2 of the rotating cover 31. As shown in Fig. 2(B), when the rotating cover 31 is rotated to the second position P2, the mating portion 30d and the mating portion 31d are mated. This mating generates resistance to the rotation of the rotating cover 31 from the second position P2 to the first position P1.
[0038] [Rotation stopper] 2(A) and 2(B), the rotating cover 31 has an engaging portion 40 as a rotation stopper that engages with the card 3 when the rotating cover 31 is located at the second position P2 to limit the rotation of the rotating cover 31 in the direction from the second position P2 to the first position P1. The engaging portion 40 is disposed corresponding to both edge portions in the width direction (X-axis direction) of the wide surface 3a of the card 3. That is, a pair of engaging portions 40 are provided at positions corresponding to both edge portions in the width direction (X-axis direction) of the wide surface 3a of the card 3.
[0039] As shown in FIGS. 2A and 2B, the engagement portion 40 includes a cantilever portion 40a and a claw portion 40b. The base end of the cantilever portion 40a is fixed to the cover main body 31a. Specifically, the cantilever portion 40a is a cantilever that extends in one direction near the edge of the side panel S2 of the cover main body 31a when the pivotable cover 31 is located at the second position P2. When located at the second position P2, the cantilever portion 40a extends in the -Y direction near the edge of the wide surface 3a of the card 3 in the width direction (X-axis direction) along the insertion slot 10a, and is a member that can elastically deform in the X-axis direction. The claw portion 40b is a portion that abuts against the card 3 and is formed at the tip of the cantilever portion 40a.
[0040] As shown in FIG. 6, the claw portion 40b is provided with a guide portion 40c and an abutment portion 40d. While the guide portion 40c of the claw portion 40b rotates from the first position P1 (see FIG. 2A) to the second position P2 (see FIG. 2B), the guide portion 40c abuts against the card 3, and the cantilever portion 40a elastically deforms outward in the width direction (X-axis direction). This allows the engagement portion 40 of the pivotable cover 31 to move beyond the edge of the card 3 to the second position P2. When the pivotable cover 31 reaches the second position P2, the guide portion 40c no longer abuts against the card 3, and the elastic deformation of the cantilever portion 40a due to abutment with the edge of the card 3 in the width direction is released. This causes the cantilever portion 40a to return to its original X-position, and the claw portion 40b moves inward in the X-axis direction so that the claw portion 40b faces the wide surface 3a of the card 3. As a result, the contact portion 40d comes into contact with the card 3.
[0041] Even if a force is applied to the engagement portion 40 to rotate the pivotable cover 31 from the second position P2 (see Figure 2(B)) toward the first position P1 (see Figure 2(A)), the edge of the card 3 is located in the +Z direction of the abutment portion 40d, so the rotation of the pivotable cover 31 toward the first position P1 is restricted.
[0042] As shown in Figures 2(B) and 3, when the rotating cover 31 is located in the second position P2, the top panel C1 and side panel C2 of the rotating cover 31 cover the contact portions 3b of the card 3 inserted into the insertion slot 10a. The shell 30 and the rotating cover 31 are in contact with each other and are at the same potential. Therefore, the shell 30 and the rotating cover 31 act as a cover that covers the electrical connector 1, including the contact portions 3b of the card 3. This further improves the connector assembly 100's ability to shield against electromagnetic waves.
[0043] [Ground contact part] 2(A) and 2(B), a portion of the top plate S1 of the rotating cover 31 is cut and bent inward to form a ground contact portion 50. When the ground contact portion 50 is located in the second position P2, it comes into contact with the conductive shield case 3c formed on the card 3. This allows the rotating cover 31 to function as an electromagnetic wave shield with the same potential as the shield case 3c of the card 3.
[0044] 2(A) and 2(B), four ground contact portions 50 are provided at equal intervals in the X-axis direction, which allows the ground contact portions 50 to absorb electromagnetic waves that enter the gap between the shielding case 3c and the top plate C1 of the rotating cover 31.
[0045] In this way, the connector cover 5 is connected to the electrode 2c of the board 2, and also contacts the shield case 3c of the card 3 at the ground contact portion 50. Therefore, the electrode 2c, the connector cover 5, and the ground contact portion 50 are at the same potential. For example, if the electrode 2c is a grounded electrode, the potential of the electrode 2c, the connector cover 5, and the shield case 3c is 0. The electrode 2c, the connector cover 5, and the shield case 3c cover the internal circuit of the card 3, the contact 11 of the electrical connector 1, and the transmission line formed by the electrode 2b, and therefore function as an electromagnetic wave shield for these.
[0046] As described above, the connector assembly 100 according to this embodiment comprises the electrical connector 1 having the housing 10 and the contacts 11, and the connector cover 5 having the shell 30 and the pivotable cover 31, and electrically connects the electrodes 2b of the substrate 2 and the contact portions 3b of the card 3. Next, the operation of connecting the connector assembly 100 to the card 3 will be described.
[0047] 7, the connector assembly 100 is mounted on the board 2 by soldering or the like. At this stage, the card 3 has not yet been mounted, and the pivotable cover 31 is in the first position P1.
[0048] Next, as shown in Fig. 8, the card 3 is inserted into the insertion slot 10a. In this state, even if the card 3 is inserted parallel to the main surface 2a of the board 2, the elastic force of the contacts 11 causes the one end of the card 3 to be inclined in a direction away from the board 2 relative to the other end inserted into the insertion slot 10a. Therefore, as shown in Fig. 2(A), the card 3 is fixed to the board 2 by the bolt 7 at the portion of the notch 3d formed in the card 3. As a result, the card 3 becomes approximately parallel to the main surface 2a of the board 2.
[0049] From this state, the rotating cover 31 is rotated from the first position P1 shown in Fig. 2(A) to the second position P2 shown in Fig. 2(B) to lock the engaging portion 40 to the card 3. This causes the connector cover 5 to cover the electrical connector 1 together with the contact portion 3b of the card 3, completing the electromagnetic shielding of the electrical connector 1. Because the engaging portion 40 is engaged with the card 3, rotation of the connector cover 5 toward the first position P1 is restricted.
[0050] To remove the card 3 from the connector assembly 100, the bolt 7 is simply removed from the board 2. This causes the elastic force of the contacts 11 to rotate the card 3 relative to the board 2, resulting in the state shown in FIG. 9. Because the engaging portion 40 is engaged with the card 3 in this manner, the rotating cover 31 also rotates together with the card 3. This allows the card 3 to be removed from the connector assembly 100 without having to disengage the card 3 from the engaging portion 40. By removing the card 3 and returning the rotating cover 31 to the first position P1, the connector assembly 100 returns to the state shown in FIG. 7.
[0051] When the card 3 is to be set again in the connector assembly 100, the operations shown in FIG. 7, FIG. 8, FIG. 2(A), and FIG. 2(B) are carried out.
[0052] Although not shown, the rotating cover 31 has a shell contact portion that comes into contact with the shell 30 when the rotating cover 31 is located at the second position P2, similar to the rotating covers 33 and 34 of the embodiments described below.
[0053] Embodiment 2 Next, a second embodiment of the present invention will be described. As shown in Figures 10 and 11, an electrical connector 8 according to this embodiment electrically connects a board 2 serving as a circuit board with a card 4A serving as a plate-like connection object. The electrical connector 8 is mounted on a main surface 2a of the board 2 by soldering or the like. Electrodes 2b are formed on the main surface 2a, and the electrical connector 8 connects to the electrodes 2b.
[0054] 10, the connector cover 6A is a cover that covers the electrical connector 8. The electrical connector 8 and the connector cover 6A are components of a connector assembly 101, which will be described later.
[0055] Like card 3 (see FIG. 1), card 4A is an M.2 card. Card 4A has a main body with a wide surface 4a. Contact portions (not shown) corresponding to contact portions 3b of card 3 are provided at one end of the main body (the end in the +Y direction in FIG. 10). However, in card 4A, the width of wide surface 4a in the X-axis direction, excluding the portion where the contact portions (not shown) are formed (the portion where the contact portions are arranged), is larger than the width of wide surface 3a of card 3 in the X-axis direction. A shield case 4c, which serves as an electromagnetic wave shield and covers the internal circuitry (not shown) and prevents external electromagnetic waves from entering, is provided on the top surface (the surface in the +Z direction) of card 4A. The shield case 4c is made of a conductive material, such as metal. As shown in FIG. 10, a semicircular notch 4d is provided at the end in the -Y direction of card 4A. Card 4A is secured to board 2 at this notch 4d with a bolt (see FIG. 2B). As a result, the card 4A is placed in a state substantially parallel to the main surface 2a of the substrate 2.
[0056] The electrical connector 8 electrically connects the electrodes 2b of the substrate 2 to the contact portions (not shown) of the card 4A. The number and arrangement pitch of the contact portions (not shown) of the card 4A are the same as those of the contact portions 3b of the card 3. Therefore, the number and arrangement pitch of the electrodes 2b formed on the main surface 2a of the substrate 2 are also the same as those of the first embodiment. Also the same as in the first embodiment, a plurality of electrodes 2c are arranged on the main surface 2a to surround the arrangement of the electrodes 2b.
[0057] [Electrical Connector] The following describes the configuration of the electrical connector 8. As shown in Fig. 11, the electrical connector 8 includes a housing 13 as a base, and contacts 11 as terminals that connect the electrodes 2b of the board 2 with contact portions (not shown) of the card 4A.
[0058] The housing 13 is made of an insulating material, such as resin. Like the housing 10 (see FIG. 1), the housing 13 has a generally rectangular parallelepiped shape with the X-axis direction as its longitudinal direction, and has a bottom surface, a top surface, a front surface F3, a back surface, and two side surfaces. The housing 13 is mounted on the substrate 2 so that the front surface F3 faces the -Y direction. The front surface F3 of the housing 13 is formed with an insertion opening 13a into which one end of a card 4A having a contact portion (not shown) formed thereon is inserted. The insertion opening 13a of the housing 13 is provided with a partition portion 13b to prevent erroneous insertion of the card 4A.
[0059] The contacts 11 are made of a conductive material, such as metal, and are engaged with the housing 13 to electrically connect the electrodes 2b of the board 2 with contact portions (not shown) of the card 4A. The number and arrangement of the contacts 11 in the electrical connector 8 are the same as those in the first embodiment.
[0060] [Connector cover] 10 and 11, the electrical connector 8 is covered by a connector cover 6A. The connector cover 6A includes a shell 32 and a pivotable cover 33.
[0061] The shell 32 is made of a conductive material, for example, a metal plate, and is similar to the shell 30 (see FIG. 2(A)) in that it covers the outer surface of the housing 13 except for the bottom surface and the front surface F3 of the housing 13 and is connected to the substrate 2. The shell 32 is also similar to the shell 30 in that it includes a top plate S1 that covers the top surface of the housing 13, side plates S2 that cover the side surfaces of the housing 13, and a back plate S3 (see FIG. 3) that covers the back surface of the housing 13, and in that the top plate S1, side plates S2, and back plate S3 are provided with substrate connection portions 32a that connect to electrodes 2c of the substrate 2. The shell 32 is also similar to the shell 30 shown in FIG. 5(A) in that it includes a shaft portion 30c and a fitting portion 30d.
[0062] The pivotable cover 33 has a cover body 33a formed by a top plate C1 and a side plate C2. The cover body 33a is the same as the cover body 31a (see FIG. 2(A)). However, the top plate C1 of the pivotable cover 33 is wider in the X-axis direction than the top plate C1 of the pivotable cover 31 (see FIG. 2(A)) to match the size of the wide surface 4a of the card 4A. The side plate C2 has a step C3 to match the shape of the wide surface 4a of the card 4A.
[0063] 11, the rotating cover 33 has an arm 33b and a shaft 33c, and the shaft 33c is fitted with the shaft 32c of the shell 32, and the rotating cover 33 is rotatable about the shaft 33c between a first position P1 (see FIG. 11) and a second position P2 (see FIG. 10). The arm 33b of the rotating cover 33 is provided with a fitting portion 33d that fits with the fitting portion 32d of the shell 32 when the rotating cover 33 is located at the second position P2.
[0064] As shown in FIG. 11, the rotating cover 33 is the same as the rotating cover 31 (see FIG. 2(A)) according to the first embodiment in that it includes a ground contact portion 50 that contacts the shield case 4c of the card 4A. The rotating cover 33 also includes a shell contact portion 60 that contacts the top plate S1 of the shell 32. As shown in FIG. 12, the top plate C1 of the rotating cover 33 has an end portion in the +Y direction bent inward, and a portion of the bent portion is cut and raised to project downward, thereby forming elastic shell contact portions 60. Five shell contact portions 60 are provided along the X-axis direction. This allows the rotating cover 33 to be connected to the shell 32 and function as a leak-free, equipotential electromagnetic wave shield.
[0065] 10 and 11, the rotating cover 33 has engagement portions 41 as rotation stoppers at positions corresponding to both edge portions in the width direction (X-axis direction) of the wide surface 4a of the card 4A. The engagement portions 41 of the rotating cover 33 engage with the card 4A to limit the rotation of the rotating cover 33 in the direction from the second position P2 to the first position P1, just like the engagement portions 40 (see FIG. 2(A)) according to the first embodiment.
[0066] 12, the engagement portion 41 includes a cantilever portion 41a and a claw portion 41b. The cantilever portion 41a is a cantilever extending in one direction from an edge of the side panel C2 of the pivoting cover 33. The cantilever portion 41a is elastically deformable in the X-axis direction. The claw portion 41b is provided at the tip of the cantilever portion 41a so as to abut against the card 4A.
[0067] As shown in FIG. 12, the engagement portion 41 is connected to the side panel C2 of the main body via the connecting portion 42. The connecting portion 42 is located closer to the center of the side panel C2 of the rotating cover 33 in the Y-axis direction in FIG. 12, rather than at the end, and is folded back inward from the end in the -Z direction. One end of the cantilever portion 41a is connected to the connecting portion 42 and extends in the -Y direction in FIG. 12. That is, the base end of the cantilever portion 41a is fixed to the edge of the side panel C2 that faces the substrate 2 when the cantilever portion 41a is located at the second position P2. In this way, the position of one end of the cantilever portion 41a can be shifted in the +Y direction, thereby ensuring the spring length of the cantilever portion 41a and increasing the amount of displacement in the X-axis direction.
[0068] Additionally, the cantilever portion 41a is connected to the side plate C2 of the rotating cover 33 via the connecting portion 42. Therefore, deformation of the cantilever portion 41a can be prevented from causing deformation of the side plate C2.
[0069] 12, while the pivotable cover 33 pivots from the first position P1 to the second position P2, the engaging portion 41 abuts against the edge of the wide surface 4a of the card 4A in the width direction (X-axis direction) along the insertion slot 10a, causing the engaging portion 41 to elastically deform outward in the width direction of the card 4A. When the pivotable cover 33 reaches the second position P2, the engaging portion 41 is released from the elastic deformation caused by the abutment against the edge of the wide surface 4a of the card 4A, and moves inward in the width direction of the card 4A, facing the wide surface 4a of the card 4A. This operation is the same as in the first embodiment.
[0070] Embodiment 3 Next, a third embodiment of the present invention will be described. As shown in Figures 13(A) and 13(B), an electrical connector 8 according to this embodiment electrically connects a board 2 serving as a circuit board with a card 4B serving as a plate-like connection object. The electrical connector 8 is mounted on a main surface 2a of the board 2 by soldering or the like. Electrodes 2b (see Figure 1) are formed on the main surface 2a, and the electrical connector 8 connects to the electrodes 2b.
[0071] 13(A) and 13(B), the connector cover 6B is a cover that covers the electrical connector 8. The electrical connector 8 and the connector cover 6B are components of a connector assembly 102, which will be described later.
[0072] Like card 4A (see FIG. 10), card 4B is an M.2 card. Card 4B has a main body with a wide surface 4a. Contact portions (not shown) corresponding to contact portions 3b of card 4B (see FIG. 1) are provided at one end V3 of the main body (the end in the +Y direction in FIGS. 13A and 13B). The width of the wide surface 4a in the X-axis direction of card 4B, excluding the portion where the contact portions (not shown) are formed (the portion where the contact portions are arranged), is the same as that of card 4A. Card 4B is also similar to card 4A in that a shield case 4c, which serves as an electromagnetic wave shield and covers the internal circuitry (not shown) and prevents electromagnetic waves from entering from the outside, is provided on the top surface (the surface in the +Z direction) of card 4B. Card 4B also has a semicircular cutout 4d at the end in the -Y direction of card 4B, which is secured to the circuit board 2 by a bolt 7.
[0073] The card 4B has six RF (Radio Frequency) connectors 4f as connector portions that mate with mating connectors. The RF connectors 4f are arranged along the X-axis direction on the edge (other end W3) of the card 4B in the -Y direction. Three RF connectors 4f are provided on each side of a notch 4d formed in the wide surface 4a. The RF connectors 4f are connectors mounted on the wide surface 4a and connect to a mating connector attached to the end of a coaxial cable (not shown), for example.
[0074] The electrical connector 8 electrically connects the electrodes 2b of the substrate 2 to the contact portions (not shown) of the card 4B. The number and arrangement pitch of the contact portions (not shown) of the card 4B are the same as those of the contact portions 3b of the card 4A (see FIG. 10). Therefore, the number and arrangement pitch of the electrodes 2b formed on the main surface 2a of the substrate 2 are also the same as those of the first embodiment. The arrangement of a plurality of electrodes 2c on the main surface 2a so as to surround the arrangement of the electrodes 2b is also the same as in the first embodiment.
[0075] [Connector cover] 13(B), the electrical connector 8 is covered by a connector cover 6B. The connector cover 6B includes a shell 32 and a pivotable cover .
[0076] The shell 32 is the same as that in the above-described second embodiment. The pivotable cover 34 has a cover body 34a formed of a top plate C1 and a side plate C2. The cover body 34a is the same as the cover body 33a (see FIG. 10) in that the top plate C1 is wider in the X-axis direction than the top plate C1 of the pivotable cover 31 (see FIG. 2(A)) to match the size of the wide surface 4a of the card 4B, and that the side plate C2 has a step C3 to match the shape of the wide surface 4a of the card 4B.
[0077] 13(B) and 14, the rotating cover 34 has an arm portion 34b and a shaft portion 34c. The shaft portion 34c is fitted with the shaft portion 32c of the shell 32, and the rotating cover 34 can be turned about the shaft portion 34c between a first position P1 and a second position P2 (see FIG. 13(B)). The arm portion 34b of the rotating cover 34 is provided with a fitting portion 34d that fits with the fitting portion 32d of the shell 32 when the rotating cover 34 is located at the second position P2.
[0078] As shown in FIGS. 13B and 14 , the rotating cover 34 is similar to the rotating cover 33 according to the second embodiment in that it includes a ground contact portion 50 that contacts the shield case 4c of the card 4B. Also, as shown in FIG. 14 , the rotating cover 34 includes a shell contact portion 61 that contacts the top plate S1 of the shell 32. As shown in FIG. 14 , the top plate C1 of the rotating cover 34 has an end portion in the +Y direction bent inward, and a portion of the bent portion is cut and raised to project downward, thereby forming the elastic shell contact portion 61. Five shell contact portions 61 are provided along the X-axis direction. This allows the rotating cover 34 to function as an electromagnetic wave shield at the same potential as the shell 32.
[0079] As described above, the card 4B is fixed to the board 2 via the bolt 7 as a fastener. The rotating cover 34 has a rotation stopper 15 on its edge in the -Y direction. When the rotating cover 34 is located at the second position P2, the rotation stopper 15 is fixed to the board 2 via the bolt 7 as a fastener, and limits the rotation of the rotating cover 34 in the direction toward the first position P1.
[0080] The rotation preventing portion 15 includes a stopper 16 as a suppressing portion that suppresses separation of the mating connector mated with the RF connector 4f from the RF connector 4f when the rotation preventing portion 15 is fixed to the substrate 2 via the bolt 7. When the rotating cover 34 is located at the second position P2, the stopper 16 covers the mating connector mated with the RF connector 4f in the Z-axis direction, restricting movement of the mating connector in the +Z direction. At this time, the stopper 16 may be in contact with the mating connector.
[0081] As shown in Figures 13(A) and 13(B), when the pivotable cover 34 is positioned at the second position P2, the other end W1, which is located opposite to one end V1 of the cover body 34a closer to the insertion port 13a, is positioned closer to the other end W3 of the card 4B than the contact portion 3b.
[0082] (1) As described above in detail, the connector cover 5 according to the above embodiment covers the electrical connector 1 that electrically connects the card 3, which is a plate-shaped connection object, to the board 2, which is a circuit board. The electrical connector 1 includes an insulating housing 10 having a front surface F3 with an insertion opening 10a formed therein, into which one end of the card 3 is inserted with the wide surface 3a of the card 3 facing the main surface 2a of the board 2, and a bottom surface F1 facing the main surface 2a of the board 2, and conductive contacts 11 attached to the housing 10, the contact portions 21 connecting to the board 2 and contact portions 22 coming into contact with contact portions 3b formed on the card 3 inserted into the insertion opening 10a.
[0083] The connector cover 5 includes a conductive shell 30 that covers the outer surface of the housing 10 except for the bottom surface F1 and the front surface F3 of the housing 10 and is connected to the board 2, and a conductive rotating cover 31 that is attached to the shell 30 so as to be rotatable between a first position P1 and a second position P2, and that is spaced apart from the contact portions 3b of the card 3 at the first position P1 and faces the contact portions 3b at the second position P2. The rotating cover 31 includes a cover main body 31a that covers the contact portions 3b when located at the second position P2, a shell contact portion 60 that contacts the shell 30 when located at the second position P2, and a ground contact portion 50 that contacts a conductive shield case 4c for grounding formed on the card 3 when located at the second position P2. In the above embodiment, when the cover body 31a is positioned at the second position P2, the other end W1 of the cover body 31a, which is opposite the one end V1 of the cover body 31a closer to the insertion slot 10a, is located between the contact portion 3b and the other end W3 of the card 3, which is opposite the one end V3 of the card 3, or is located closer to the other end W3 of the card 3 than the contact portion 3b. Therefore, the pivotable cover 31 can cover the contact portion 3b of the card 3 and can prevent electromagnetic waves from passing between the pivotable cover 31 and the shell 30 and between the pivotable cover 31 and the card 3. This allows for more robust blocking of electromagnetic waves from entering and leaking from the outside. The other end W1 and the other end (open end) W2 of the cover body 31a may be located outward (in the -Y direction) from the other end W3 of the card 3, as long as the pivotable cover 31 can cover the contact portion 3b of the card 3.
[0084] (2) Furthermore, according to the above embodiment, the rotating cover 31 includes the engaging portion 40 as a rotation stopper that limits the rotation of the rotating cover 31 in the direction from the second position P2 to the first position P1 when the rotating cover 31 is located at the second position P2. This prevents the rotating cover 31 from accidentally coming off the card 3.
[0085] (3) According to the above embodiment, the engaging portion 40 has a base end fixed to the cover main body 31a, and includes an elastically deformable cantilever portion 40a disposed to extend in the direction in which the card 3 is inserted or removed near (opposed to) an edge of the wide surface 3a of the card 3 in the width direction (X-axis direction) along the insertion slot 10a when the rotating cover 31 is positioned at the second position P2, and a claw portion 40b formed at the tip of the cantilever portion 40a. When the rotating cover 31 rotates from the first position P1 to the second position P2, the claw portion 40b of the engaging portion 40 abuts against the edge of the card 3 in the width direction. At this time, the cantilever portion 40a elastically deforms outward in the width direction of the card 3, and the rotating cover 31 reaches the second position P2. Then, the elastic deformation of the cantilever beam portion 40a caused by contact with the widthwise edge of the card 3 is released, and the claw portion 40b faces the wide faces 3a, 4a of the card 3. In this way, the connector cover 5 can be engaged with the card 3 and prevented from opening (the pivoting cover 31 can be prevented from pivoting from the second position P2 toward the first position P1).
[0086] (4) Furthermore, according to the above embodiment, the engaging portions 40 are disposed in correspondence with both widthwise edge portions of the wide surface 3a of the card 3. In this manner, by providing the engaging portions 401 in correspondence with both widthwise edge portions of the card 3, the pivotable cover 31 can be more reliably locked to the card 3.
[0087] (5) According to the second embodiment, the cover body 33a includes an upper surface plate C1 facing the upper surface F2 of the housing 10 and a pair of side surfaces C2 facing the pair of side surfaces F5 of the housing 10. The base end of the cantilever portion 41a is fixed to an edge of the side surface plate C2 facing the substrate 2 when the cantilever portion 41a is located at the second position P2. This increases the spring length of the cantilever portion 41a, thereby increasing the amount of displacement in the X-axis direction.
[0088] (6) Furthermore, according to the third embodiment, the card 4B is fixed to the board 2 via the bolt 7, and the rotation stopper 15 is fixed to the board 2 via the bolt 7 when the card 4B is located at the second position P2, thereby restricting the rotation of the rotating cover 34. In this way, the rotation stopper 15 is not limited to the cantilever-shaped engaging portion 40 or the like.
[0089] (7) According to the third embodiment, the card 4B includes an RF connector 4f that mates with a mating connector (not shown). The rotation stopper 15 includes a stopper 16 that prevents the mating connector from separating from the RF connector 4f when the rotation stopper 15 is fixed to the board 2 via the bolt 7. This configuration can further strengthen the connection between the RF connector 4f formed on the card 4B and the mating connector.
[0090] (8) According to the above embodiment, the shell 30 is connected to the electrode 2c, which is the ground electrode of the substrate 2. In this way, the potential of the shell 30 and the rotating cover 31 can be set to zero, so that they can function as a stronger electromagnetic shield.
[0091] (9) Furthermore, according to the above embodiment, the shell 30 includes a top plate S1 that covers the top surface F2 of the housing 10, a side plate S2 that covers the side surface F5 of the housing 10, and a back plate S3 that covers the back surface F4 of the housing 10. The top plate S1, the side plate S2, and the back plate S3 cover the board connecting portions 21 of the contacts 11 arranged on the back surface F4 of the housing 10. This arrangement effectively blocks electromagnetic waves from entering and emitting from the contacts 11 arranged on the back surface F4 of the housing 10 to the outside world.
[0092] (10) The connector assembly 100 according to the above embodiment includes a housing 10, contacts 11, a shell 30, and a pivotable cover 31. The housing 10 is an insulating member having a front surface F3 formed with an insertion opening 10a through which one end of the card 3 is inserted with the wide surface 4a of the card 3 facing the main surface 2a of the board 2, and a bottom surface F1 (see FIG. 3) facing the main surface 2a of the board 2. The contacts 11 are conductive members attached to the housing 10 and have board connection portions 21 connected to the board 2 and contact portions 22 that come into contact with contact portions 3b formed on the card 3 inserted into the insertion opening 10a. The shell 30 is a conductive member that covers the outer surface of the housing 10 except for the bottom surface F1 and the front surface F3 of the housing 10 and is connected to the board 2. The pivotable cover 31 is attached to the shell 30 so as to be pivotable between a first position P1 and a second position P2. The pivotable cover 31 is a conductive member that is spaced apart from the contact portion 3b of the card 3 at the first position P1 and faces the contact portion 3b at the second position P2. The pivotable cover 31 includes a cover main body 31a that covers the contact portion 3b when the pivotable cover 31 is located at the second position P2, a shell contact portion 60 that contacts the shell 30 when the pivotable cover 31 is located at the second position P2, and a ground contact portion 50 that contacts a conductive shield case 4c for grounding formed on the card 3 when the pivotable cover 31 is located at the second position P2. When the pivotable cover 31 is located at the second position P2, the other end W1 of the cover main body 31a, which is opposite to the one end closer to the insertion slot 10a, is located between the contact portion 3b and the other end W3 of the card 3, which is opposite to the one end V3 of the card 3, or is located closer to the other end W3 of the card 3 than the contact portion 3b. Therefore, the rotating cover 33 can cover the contact portion 3b of the card 4A, and can also prevent electromagnetic waves from passing between the rotating cover 31 and the shells 30, 32, and between the rotating cover 31 and the card 3. This makes it possible to more firmly block the ingress and egress of electromagnetic waves from the outside.
[0093] In the above embodiment, the cards 3, 4A, and 4B are M.2 cards. However, this is not limiting. They may be cards of other standards (for example, SD), or may be communication cards with built-in wireless antennas.
[0094] This invention allows various embodiments and modifications without departing from the broad spirit and scope of this invention. Furthermore, the above-described embodiments are intended to explain this invention and do not limit the scope of this invention. That is, the scope of this invention is defined by the claims, not the embodiments.
