Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of a connector-board assembly and an electronic device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by this embodiment.

[0011] Hereinafter, a connector - substrate assembly according to an embodiment of the present invention and an example of an electronic device will be described in detail with reference to the drawings. Note that the present invention is not limited by this example.

[0012] FIG. 1 is a perspective view of a notebook PC (electronic device) 10 which is an electronic device according to an embodiment of the present invention. The notebook PC 10 includes a connector - substrate assembly 12 according to an embodiment of the present invention. The connector - substrate assembly 12 is incorporated inside a housing 14 of the notebook PC 10. The electronic device according to the present invention is not limited to the notebook PC 10, and may be, for example, a desktop PC or a mobile tablet terminal.

[0013] For the notebook PC 10, a lid 16 can be opened and closed with respect to the housing 14 by a hinge 18, and closing the lid 16 makes it compact and suitable for mobile use.

[0014] A keyboard device 20 and a touch pad 22 are provided on the housing 14. On the front surface of the lid 16, a display device 24 that occupies most of its area, and speakers and a camera (not shown) are provided.

[0015] The connector - substrate assembly 12 is incorporated in the housing 14. The connector - substrate assembly 12 includes a receptacle connector 26 and a substrate 28. The substrate 28 is the main substrate in the notebook PC 10 and is provided substantially across the left and right ends inside the housing 14. A CPU 29 that controls the entire notebook PC 10 is mounted on the substrate 28. The substrate 28 on which the receptacle connector 26 is mounted in the connector - substrate assembly 12 may be a sub - substrate different from the main substrate.

[0016] For convenience of explanation, around the receptacle connector 26, the outer side of the housing 14 is regarded as the outside, and the inside of the housing 14 is regarded as the inside. Also, with reference to the substrate 28, the side where many components are mounted is the upper side, and the opposite side is the lower side. The upper and lower reference standards may be opposite to those of the housing 14, and the side where the keyboard device 20 is provided may be the lower side. These directional designations are for convenience of explanation and the usage mode of the electronic device 10 is not limited thereto.

[0017] Hereinafter, the receptacle connector 26A according to the first embodiment (see FIG. 2), the receptacle connector 26B according to the second embodiment (see FIG. 10), and the receptacle connector 26C according to the third embodiment (see FIG. 13) related to the receptacle connector 26 will be described in order. The receptacle connectors 26A to 26C are, for example, a standardized USB Type-C or a small connector equivalent to the USB, and are used for data transmission and charging. The receptacle connectors 26A to 26C may be HDMI (High-Definition Multimedia Interface, registered trademark) or the like. The receptacle connectors 26A to 26C are mounted on the substrate 28 but are not soldered and are detachable.

[0018] FIG. 2 is a perspective view of the receptacle connector 26A according to the first embodiment as viewed obliquely from the outside. FIG. 3 is a perspective view of the receptacle connector 26A as viewed obliquely from the inside. FIG. 4 is a perspective view of the receptacle connector 26AA according to a modified example. FIG. 5 is a cross-sectional side view taken along the line V-V in FIG. 1. FIG. 6 is a perspective view of the receptacle connector 26A with the plug holding cylinder 30 and the shells 32, 34 removed. FIG. 7 is a view showing a modified example of the folded portion 36c, (a) is a schematic diagram showing the folded portion 36ca according to the first modified example, (b) is a schematic diagram showing the folded portion 36cb according to the second modified example, (c) is a schematic diagram showing the folded portion 36cc according to the third modified example, and (d) is a schematic diagram showing the folded portion 36cd according to the fourth modified example.

[0019] The receptacle connector 26A is of a so-called top-mount type mounted on one side of the substrate 28, and includes a plug holding cylinder 30, a first shell 32, a second shell 34, a plurality of electrode lines 36, a holder 38, and a first relay connector 40. Among these, the plug holding cylinder 30 is the outermost, and the first relay connector 40 is the innermost and faces downward.

[0020] The plug holding cylinder 30 has a flat shape with rounded corners and is generally made of metal. A connector hole 14a (see FIG. 1) is formed in the side surface of the housing 14, and the plug insertion opening 30a of the plug holding cylinder 30 is exposed from the connector hole 14a. A plug connector (not shown) is inserted and connected to the plug insertion hollow portion 30b corresponding to the inside of the plug insertion opening 30a. The plug connector can be inserted upside down. The plug holding cylinder 30 is in a state where its lower surface rests on the upper surface of the substrate 28. A brand pattern 41 (see FIG. 5) is provided on the substrate 28 at the location where the plug holding cylinder 30 rests to achieve electrical conduction.

[0021] The holder 38 is a portion that covers and holds the electrode lines 36. The holder 38 covers the electrode lines 36 without any air layer gaps. The holder 38 has an outer electrode holder 42, an inner terminal holder 44, and an intermediate holder 46 between the electrode holder 42 and the terminal holder 44. The electrode holder 42, the terminal holder 44, and the intermediate holder 46 are integrally formed or the respective boundary portions are fixed by adhesion or the like. The holder 38 is made of a resin material. Among these, the electrode holder 42 and the terminal holder 44 are basically made of the same material, but the intermediate holder 46 is made of a different material.

[0022] The electrode holder 42 and the terminal holder 44 are made of a relatively hard and substantially rigid material such as, for example, LCP (Liquid Crystal Polymer), and can securely hold the electrode line 36. The intermediate holder 46 is made of a material having non-flexible bulk elasticity such as, for example, an elastomer (including natural rubber, silicone rubber, etc.). In the present application, non-flexible means having no flexibility. Flexibility is the property that a sheet, film, string, etc. can bend and curve, and basically the volume hardly changes even when deformed. On the other hand, bulk elasticity is the property that the volume changes due to a pressure change, and is substantially the same as compressibility. A flexible material will bend due to its own weight and cannot maintain its shape, while a material having non-flexible bulk elasticity will hardly deform under its own weight and can maintain its shape almost.

[0023] Also, from the electrical characteristics, it is desirable that the electrode line 36 does not touch the air in the middle and the relative dielectric constants of the electrode holder 42, the terminal holder 44, and the intermediate holder 46 covering the surface are the same. This is because if the relative dielectric constants of the materials covering the surface of the electrode line 36 are significantly different, so-called impedance matching becomes inconsistent and high-frequency signals are reflected.

[0024] On the other hand, since the required mechanical characteristics of the electrode holder 42, the terminal holder 44, and the intermediate holder 46 are different, it is difficult to make the materials and relative dielectric constants exactly the same in design, and the relative dielectric constants are set to be approximately equal within an allowable range. In this embodiment, the relative dielectric constant of the LCP applied to the electrode holder 42 and the terminal holder 44 is about 3.4. The relative dielectric constant of the elastomer applied to the intermediate holder 46 in this embodiment is about 2.9 to 3.1. Thus, in order to prevent the impedance from becoming discontinuous in the receptacle connector 26, the electrode line 36 is covered with a material having a substantially equal relative dielectric constant in the corresponding portion in the receptacle connector 26.

[0025] The electrode holder 42 is mainly inside the plug holder cylinder 30 and has a flange portion 42a that fits into and is fixed to the innermost part of the plug holder cylinder 30, and a tongue portion 48 that protrudes outward from the flange portion 42a. The tongue portion 48 is at approximately the middle in the vertical direction in the plug insertion hollow portion 30b of the plug holder cylinder 30 and extends from the flange portion 42a toward the outside of the inside of the plug holder cylinder 30. The tip portion 48b of the tongue portion 48 is slightly thinner than the inner base end portion 48a, and an inclined step 48c is formed therebetween. The tip of the tongue portion 48 is slightly inside the outer end portion of the plug holder cylinder 30. A metal plate 50 is provided at the vertical middle portion of the tongue portion 48. The metal plate 50 electromagnetically shields the tongue portion 48 at the vertical middle and ensures strength.

[0026] The terminal holder 44 has a shape that is generally square in side view (see FIG. 5). The inner and outer dimension of the terminal holder 44 is about 1 / 2 of the plug holder cylinder 30 in this embodiment. The lower surface of the terminal holder 44 is at a position slightly higher than the surface 28a of the substrate 28, and the upper surface is at a position slightly higher than the plug holder cylinder 30. The first relay connector 40 is provided at the lower part of the terminal holder 44. The entire terminal holder 44 may also serve as the first relay connector 40.

[0027] The intermediate holder 46 has a vertically long rectangular shape with the upper and lower surface positions the same as those of the terminal holder 44 in side view (see FIG. 5). The inner and outer dimension of the intermediate holder 46 is smaller than that of the terminal holder 44 and is about 1 / 3 of the plug holder cylinder 30 in this embodiment.

[0028] The electrode line 36 is continuous from the electrode 36a connected to the plug-side electrode to the relay terminal 36b of the first relay connector 40 and is held by the holder 38. The electrodes 36a are provided in two rows above and below the tongue portion 48, and a total of 24 are provided above and below. The electrodes 36a are exposed on the upper and lower surfaces of the tip portion 48b and are adapted to contact the electrodes of the plug connector.

[0029] The electrode line 36 has a folded-back portion 36c in the portion covered by the intermediate holder 46. The folded-back portion 36c turns upward at a sharp angle from the boundary point P1 with the electrode holder 42 toward the inside, forms an inverted V shape, turns downward at a sharp angle, and then reaches the boundary point P2 with the terminal holder 44 through a substantially horizontal portion. The boundary point P1 and the boundary point P2 are at the same height. Such a folded-back portion 36c can absorb the change in path length when the relative positions of the electrode holder 42 and the terminal holder 44 change. A thin slit 46a may be provided at the center of the inverted V shape formed by the folded-back portion 36c as shown by the phantom line to make the folded-back portion 36c easier to deform.

[0030] The folded-back portion 36c can take various forms as shown in FIG. 7. That is, between the boundary point P1 and the boundary point P2, it may be S-shaped like the folded-back portion 36ca in FIG. 7(a), or horizontally S-shaped like the folded-back portion 36cb in FIG. 7(b), or Z-shaped like the folded-back portion 36cc in FIG. 7(c), or crank-shaped like the folded-back portion 36cd in FIG. 7(d). In other words, the electrode line 36 may have a curved portion or a bent portion between the two points of the boundary point P1 and the boundary point P2.

[0031] The electrode line 36 enters the terminal holder 44 from the boundary point P2, turns vertically upward from the boundary point P2 toward the inside, forms an inverted U shape, turns vertically downward, and reaches the relay terminal 36b. The outer electrode 36a of the electrode line 36 has two levels above and below the tongue portion 48, while the inner relay terminal 36b has two rows in the inner-outer direction inside the first relay connector 40.

[0032] FIG. 8 is a schematic cross-sectional view of the board-to-board connector 52. The board-to-board connector 52 is composed of a first relay connector 40 and a second relay connector 54. In this embodiment, the first relay connector 40 has a plug structure, and the second relay connector 54 has a socket structure. The second relay connector 54 has two rows of relay terminals 54a in the inner and outer directions corresponding to the relay terminals 36b. The second relay connector 54 is fixed by soldering the relay terminals 54a to the surface 28a of the board 28. The board-to-board connector 52 is fitted into the upward opening of the second relay connector 54 by lowering the first relay connector 40, and the relay terminals 36b and the relay terminals 54a come into contact with each other to conduct electricity. That is, the receptacle connector 26A and the board 28 are detachably coupled by the first relay connector 40 on the receptacle connector 26A side and the second relay connector 54 on the board 28 side.

[0033] The first relay connector 40 and the second relay connector 54 have a floating structure capable of absorbing the tolerances of the respective relay terminals 36b and 54a. That is, the two rows of relay terminals 36b have J-shaped forms with curved tips facing opposite directions, while the relay terminal 54a has one side vertical along the housing wall and the other side curved so as to sandwich the relay terminal 36b, and the two rows are opposite to each other. The relay terminal 36b and the relay terminal 54a can be relatively displaced while maintaining the conduction state in the vertical direction and the inner and outer directions by elastically contacting the straight portion and the curved portion. Also, relative displacement is possible while sliding in the direction perpendicular to the paper surface. Furthermore, relative displacement is possible in the rotational direction about each direction as an axis. The floating structure is not limited to this example.

[0034] FIG. 9 is a schematic cross-sectional view of the board-to-board connector 52A according to a modified example. In the board-to-board connector 52A, the second relay connector 54 has a card-edge type, and detachment is possible by moving the first relay connector 40 in the inner and outer directions.

[0035] As shown in FIGS. 2 and 3, the plug holding cylinder 30 has its side and upper surfaces covered by a first shell 32 made of metal, and the intermediate holder 46 and the terminal holder 44 have their side and upper surfaces covered by a second shell 34 made of metal.

[0036] The first shell 32 is in a flat horseshoe shape, and the second shell 34 is in a square shape with an opening at the bottom. When viewed from the outside (the side where the plug is inserted), the second shell 34 is larger than the first shell 32. When viewed from the outside, the first shell 32 is provided with fixing pieces 32a protruding on both sides for fixing to the substrate 28. Similarly, the second shell 34 is provided with fixing pieces 34a protruding on both sides for fixing to the substrate 28. The fixing pieces 32a and 34a are adjacent to each other in the inner and outer directions. The outer fixing piece 32a is provided with a pressing piece 32b for pressing the outer edge of the inner fixing piece 34a from above, ensuring the stability, positioning, and electrical connection between the fixing pieces 34a. The fixing pieces 32a and 34a are formed with screw insertion holes. The substrate 28 is formed with screw insertion holes 28c (see FIG. 11) at positions corresponding to the fixing pieces 32a and 34a.

[0037] Inside the operation panel 14b of the housing 14 (also see FIG. 1), four studs 56 are erected at positions corresponding to the fixing pieces 32a and 34a. The top of the stud 56 has a stepped shape (see FIG. 11), the small diameter part 56a fits into the screw insertion hole 28c of the substrate 28, and the large diameter part 56b supports the back surface 28b of the substrate 28. By screwing a screw 58 onto the stud 56, the fixing pieces 32a and 34a and the substrate 28 are clamped and fixed by the head of the screw 58 and the large diameter part 56b of the stud 56. That is, the fixing pieces 32a and 34a of the receptacle connector 26A are fixed to the substrate 28 via the stud 56 by the screw 58. The fixing pieces 32a and 34a are in contact with the ground of the substrate 28.

[0038] The inner second shell 34 has three fin pieces 60 that project outward and obliquely from the upper surface and both side surfaces. The fin pieces 60 are elastically in contact with the upper surface and both side surfaces of the first shell 32 to close the boundary portion and ensure conduction. The fin pieces 60 may project inward from the first shell 32 and contact the second shell 34, but it is more appropriate to provide them on the relatively larger second shell 34.

[0039] The receptacle connector 26A is fixed to the substrate 28 by fixing pieces 32a, 34a and the first relay connector 40, and there is basically no soldering. Among these, the first relay connector 40 is mainly for electrical connection, and the fixing pieces 32a, 34a are mainly for mechanical connection. Therefore, excessive force does not act on the first relay connector 40.

[0040] As shown in FIG. 3, the inner surface of the second shell 34 is open and the terminal holder 44 is exposed, but as shown in FIG. 4, it may have an inner wall 34b that covers the terminal holder 44.

[0041] In the notebook PC 10 and the connector - substrate assembly 12 configured as described above, the receptacle connector 26A and the substrate 28 are detachably coupled with the first relay connector 40 on the receptacle connector 26A side and the second relay connector 54 on the substrate 28 side. Therefore, even when an excessive force beyond expectation is applied to the receptacle connector 26A and it is damaged, it is possible to replace the relatively inexpensive receptacle connector 26A alone, and the relatively expensive substrate 28 can continue to be used as it is, reducing the cost burden on the user.

[0042] Further, the holder 38 of the receptacle connector 26A includes an electrode holder 42 on the side of the electrode 36a, a terminal holder 44 on the side of the relay terminal 36b, and an intermediate holder 46 therebetween. The intermediate holder 46 is non-flexible and has volume elasticity. If a flexible sheet is applied to this part, the shape cannot be maintained, and the electrode holder 42 and the terminal holder 44 will become substantially separate bodies. However, since the non-flexible intermediate holder 46 as in this embodiment maintains its shape, the electrode holder 42, the terminal holder 44, and the intermediate holder 46 are integral parts, which are easy to handle and assemble. As described above, the intermediate holder 46 is smaller than the electrode holder 42 and the terminal holder 44. By providing the intermediate holder 46, the receptacle connector 26A does not have a special shape and is maintained in a small size, and is almost the same size as the USB Type-C connector according to the prior art.

[0043] In the holder 38, since the intermediate holder 46 is provided, a slight deviation in the relative positions of the electrode holder 42 and the terminal holder 44 is allowed. When an excessive force beyond expectation is applied to the electrode holder 42 via the plug connector or the like during and after the insertion of the plug connector and the tongue portion 48 is damaged, the action of the external force is absorbed by the intermediate holder 46.

[0044] Also, since the electrode line 36 has a curved portion or a bent portion between two boundary points P1 with the electrode holder 42 and P2 with the terminal holder 44 at the folded-back portion 36c inside the intermediate holder 46, even if an external force by a plug connector or the like is applied to the electrode holder 42 and the relative position with the terminal holder 44 changes, the change in the path length between them can be absorbed. The folded-back portion 36c can absorb changes in three orthogonal directions and three torsional directions. Therefore, there is almost no influence on the terminal holder 44, and the substrate 28 is not damaged via the terminal holder 44.

[0045] The electrode holder 42, the terminal holder 44, and the intermediate holder 46 have substantially equal relative dielectric constants, and can suppress transmission loss when a high-speed signal flows through the electrode line 36.

[0046] The receptacle connector 26A has a first shell 32 made of a metal material that covers the plug holding cylinder 30 and is fixed to the substrate 28, and a second shell 34 made of a metal material that covers the terminal holder 44 and is fixed to the substrate 28. It protects the holder 38 and provides an electromagnetic shielding effect. Also, since the first shell 32 and the second shell 34 are separate bodies, external forces applied to the plug holding cylinder 30 and the electrode holder 40 do not transfer to the terminal holder 44.

[0047] The first shell 32 and the second shell 34 are blocked from each other's boundary by fin pieces 60 protruding from one to the other, so electromagnetic leakage from this boundary can be suppressed.

[0048] The first relay connector 40 and the second relay connector 54 have a floating structure capable of absorbing the tolerances of their respective relay terminals 36b, 54a. Therefore, even if a force on the electrode holder 42 acts on the terminal holder 44, it is absorbed by the floating structure and has no effect on the substrate 28.

[0049] Next, the receptacle connector 26B according to the second embodiment will be described. For the receptacle connectors 26B and 26C, the same components as those of the above receptacle connector 26A are denoted by the same reference numerals and their detailed description is omitted.

[0050] FIG. 10 is an exploded perspective view of the receptacle connector 26B, the substrate 28, and the housing 14. FIG. 11 is a view of the receptacle connector 26B seen from the outside. FIG. 12 is a perspective view of the receptacle connector 26B, the substrate 28, and the housing 14 seen from the inside. The screw 58 is omitted in FIG. 12.

[0051] The above receptacle connector 26A is of the so-called top mount type, while the receptacle connector 26B is of the so-called mid-mount type that fits into a notch 28d formed in the substrate 28. The receptacle connector 26B has a portion of the plug holding cylinder 30 fitting into the notch 28d, the terminal holding body 44 is located above the substrate 28 as in the above example, and the first relay connector 40 is inserted and removed in the vertical direction with respect to the second relay connector 54.

[0052] The receptacle connector 26B has a metal shell 62. The shell 62 corresponds to the above shells 32, 34 and has an electromagnetic shielding and a fixing function with respect to the substrate 28. The shell 62 has a cylindrical portion 62a covering the periphery of the plug holding cylinder 30 and an inner top plate 62b inside the cylindrical portion 62a. The plug holding cylinder 30 and the cylindrical portion 62a are fixed by claws 30c. The lower half of the plug holding cylinder 30 and the cylindrical portion 62a fits into the notch 28d.

[0053] The inner top plate 62b is at a position slightly higher than the cylindrical portion 62a, and the space therebetween is connected by a stepped wall 62c. Bent pieces 62d bent downward are provided at both ends of the inner top plate 62b. The inner top plate 62b, the stepped wall 62c, and the bent pieces 62d cover the terminal holding body 44 but are not fixed. Therefore, an external force is not transmitted between the plug holding cylinder 30 and the terminal holding body 44.

[0054] Portions extending from the upper surface to the side surface on both sides of the cylindrical portion 62a are cut out in a square rectangle shape and folded back laterally to form fixing pieces 64R, 64L. In FIGS. 10 and 11, the right side is the fixing piece 64R and the left side is the fixing piece 64L. The fixing pieces 64R, 64L correspond to the above fixing pieces 32a, and the receptacle connector 26B is fixed to the substrate 28 by the fixing pieces 64R, 64L. A screw hole for inserting a screw 58 is formed in the fixing piece 64R, but the fixing piece 64L has a shape that opens laterally instead of a hole.

[0055] Next, the receptacle connector 26C according to the third embodiment will be described.

[0056] FIG. 13 is a perspective view showing a state in which two receptacle connectors 26C are mounted on a substrate 28. FIG. 14 is a view seen from the outside showing a state in which two receptacle connectors 26C are mounted on the substrate 28. In the receptacle connector 26C, the fixing pieces 64R and 64L in the above receptacle connector 26B are replaced with fixing pieces 66R and 66L. The two receptacle connectors 26C are mounted side by side along the surface of the substrate 28 as seen from the outside.

[0057] The two fixing pieces 66R and 66L have different heights. Specifically, the fixing piece 66R on the right side is higher in the direction perpendicular to the surface of the substrate 28 than the fixing piece 66L on the left side. The height difference is equal to the plate thickness t of the fixing pieces 66R and 66L, but it may be adjusted by a spacer or the like. The fixing piece 66L on the left side in the adjacent receptacle connector 26C on the right side and the fixing piece 66R on the right side in the receptacle connector 26C on the left side overlap and are fixed by a common screw 58 and stud 56. The stud 56R (see FIG. 14) that supports the fixing piece 66R in the receptacle connector 26C on the right side in FIG. 14 has a small diameter portion 56a that is higher by the plate thickness t compared to the other studs 56, and supports the receptacle connector 26C so as to be parallel to the substrate 28.

[0058] The receptacle connector 26C is fixed by the fixing pieces 66R and 66L instead of soldering in order to be replaceable with respect to the substrate 28. When a plurality of them are mounted adjacent to each other, the total dimension in the parallel direction can be suppressed by overlapping the fixing piece 66R and the fixing piece 66L. Three or more receptacle connectors 26C may be mounted side by side while overlapping the fixing pieces 66R and 66L, or only one may be mounted. When a member corresponding to the second shell 34 in the above receptacle connector 26A is provided in the receptacle connector 26C, the heights of the two fixing pieces 34a of the second shell 34 may be changed like the fixing pieces 66R and 66L. The receptacle connector 26C shown in FIGS. 13 and 14 is of a mid-mount type, but may be of a top-mount type.
