DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, embodiments of a connector-circuit 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 to these embodiments.

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

[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 and board assembly 12 according to an embodiment of the present invention. The connector and board 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] The notebook PC 10 has a cover 16 that can be opened and closed by a hinge 18 with respect to a housing 14, and by closing the cover 16, the notebook PC 10 becomes compact and is suitable for mobile use.

[0014] The housing 14 is provided with a keyboard device 20 and a touch pad 22. On the front side of the cover 16, a display device 24 that occupies most of the area, as well as a speaker and a camera (not shown) are provided.

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

[0016] For ease of explanation, the side of the housing 14 around the receptacle connector 26 is referred to as the outside, and the inside of the housing 14 is referred to as the inside. Also, using the board 28 as a reference, the side on which more components are mounted is referred to as the top, and the opposite side is referred to as the bottom. This reference for up and down may be reversed with respect to the housing 14, with the side on which the keyboard device 20 is provided being referred to as the bottom. These designations of directions are for ease of explanation, and the manner of use of the electronic device 10 is not limited to this.

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

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

[0019] The receptacle connector 26A is of a so-called top mount type, which is mounted on one surface of the substrate 28, and has a plug holding cylinder 30, a first shell 32, a second shell 34, a plurality of electrode lines 36, a holding body 38, and a first relay connector 40. Of these, the plug holding cylinder 30 is on the outermost side, and the first relay connector 40 is on the innermost side, facing 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 of the housing 14, and a 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 into a plug insertion hollow portion 30b corresponding to the inside of the plug insertion opening 30a. The plug connector can be inserted upside down. The bottom surface of the plug holding cylinder 30 rests on the top 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, ensuring electrical continuity.

[0021] The holder 38 is a part that covers and holds the electrode lines 36. The holder 38 covers the electrode lines 36 with no air 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 molded, or each boundary portion is fixed by adhesive or the like. The holder 38 is made of a resin material, and while the electrode holder 42 and the terminal holder 44 are basically made of the same material, 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 LCP (Liquid Crystal Polymer), and can reliably hold the electrode line 36. The intermediate holder 46 is made of a material having non-flexible volume elasticity, such as elastomer (including natural rubber, silicone rubber, etc.). In this application, non-flexibility means that there is no flexibility. Flexibility is the property of being able to bend and bend, such as in a sheet, film, or string, and basically the volume hardly changes even if it is deformed. In contrast, volume elasticity is the property of changing the volume due to a change in pressure, and is substantially the same as compressibility. A flexible material bends due to its own weight and cannot maintain its shape, whereas a non-flexible material having volume elasticity does not deform much due to its own weight and can almost maintain its shape.

[0023] In addition, from the viewpoint of electrical characteristics, it is desirable that the electrode line 36 does not come into contact with air along the way, and that the electrode holder 42, terminal holder 44, and intermediate holder 46 that cover the surface have the same relative dielectric constant. If the relative dielectric constants of the materials that cover the surface of the electrode line 36 differ significantly, so-called impedance matching will be inconsistent, causing high-frequency signals to be reflected.

[0024] On the other hand, since the required mechanical properties are different for the electrode holder 42, the terminal holder 44, and the intermediate holder 46, it is difficult to design them with completely identical materials and dielectric constants, and the dielectric constants are set to be approximately equal within the allowable range. In this embodiment, the dielectric constant of the LCP used for the electrode holder 42 and the terminal holder 44 is approximately 3.4. In this embodiment, the dielectric constant of the elastomer used for the intermediate holder 46 is approximately 2.9 to 3.1. In this way, in order to prevent impedance discontinuity in the receptacle connector 26, the electrode lines 36 are covered in the relevant portions of the receptacle connector 26 with materials having approximately the same dielectric constant.

[0025] The electrode holder 42 has a flange portion 42a that is mainly located inside the plug holder cylinder 30 and is fitted and 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 located at approximately the middle portion in the vertical direction of the plug insertion hollow portion 30b of the plug holder cylinder 30, and extends from the flange portion 42a toward the outside inside the plug holder cylinder 30. The tongue portion 48 has an outer tip portion 48b that is slightly thinner than an inner base end portion 48a, and an inclined step 48c is formed between them. 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 middle portion of the tongue portion 48. The metal plate 50 electromagnetically shields the tongue portion 48 at the middle portion between the vertical direction and ensures its strength.

[0026] The terminal holder 44 has a shape with approximately equal length and width when viewed from the side (see FIG. 5). In this embodiment, the inner and outer dimensions of the terminal holder 44 are approximately half that of the plug holding cylinder 30. The lower surface of the terminal holder 44 is located slightly higher than the surface 28a of the board 28, and the upper surface is located slightly higher than the plug holding 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] When viewed from the side (see FIG. 5), intermediate holder 46 has a vertically elongated rectangular shape with the upper and lower surfaces positioned in the same positions as terminal holder 44. The inner and outer dimensions of intermediate holder 46 are smaller than terminal holder 44, and in this embodiment are approximately 1 / 3 of those of plug holding cylinder 30.

[0028] The electrode line 36 continues from the electrode 36a, which connects to the plug-side electrode, to the relay terminal 36b of the first relay connector 40, and is held by a holder 38. The electrodes 36a are provided in two stages, above and below the tongue portion 48, for a total of 24 electrodes on the top and bottom. The electrodes 36a are exposed on the top and bottom surfaces of the tip portion 48b, and are adapted to come into contact with the electrodes of the plug connector.

[0029] The electrode line 36 has a folded portion 36c in a portion covered by the intermediate holder 46. The folded portion 36c is configured to be inwardly directed upward at a steep angle from a boundary point P1 with the electrode holder 42, form an inverted V shape, and then be directed downward at a steep angle, and then reach a boundary point P2 with the terminal holder 44 via a nearly horizontal portion. The boundary points P1 and P2 are at the same height. Such a folded portion 36c can absorb a change in the path length that occurs when the relative positions of the electrode holder 42 and the terminal holder 44 change. A thin slit 46a may be provided in the center of the inverted V shape formed by the folded portion 36c, as shown by an imaginary line, to make the folded portion 36c easier to deform.

[0030] The turn-back portion 36c may have various shapes as shown in Fig. 7. That is, between the boundary point P1 and the boundary point P2, it may be S-shaped as in the turn-back portion 36ca in Fig. 7(a), it may be a sideways S-shaped as in the turn-back portion 36cb in Fig. 7(b), it may be Z-shaped as in the turn-back portion 36cc in Fig. 7(c), or it may be crank-shaped as in the turn-back portion 36cd in Fig. 7(d). In other words, it is sufficient that the electrode line 36 has a curved or 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 electrode line 36 is in two rows above and below the tongue portion 48 in the outer electrode 36a, but in the inner relay terminal 36b, it is in two rows in the inward and outward directions 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. By lowering the first relay connector 40, the board-to-board connector 52 fits into the upward opening of the second relay connector 54, and the relay terminals 36b and the relay terminals 54a come into contact with each other to establish electrical continuity. In other words, the receptacle connector 26A and the board 28 are detachably coupled to 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 tolerance of the relay terminals 36b and 54a. That is, the two rows of relay terminals 36b are J-shaped with curved tips in opposite directions, whereas the relay terminals 54a have one side vertical along the housing wall and the other side curved to sandwich the relay terminals 36b, so that the two rows are in opposite directions. The linear and curved parts of the relay terminals 36b and 54a are elastically in contact with each other, so that they can be displaced relative to each other while maintaining electrical continuity in the up-down and inward-outward directions. They can also be displaced relative to each other while sliding in the direction perpendicular to the paper surface. They can also be displaced relative to each other in the rotational direction around each direction. The floating structure is not limited to this example.

[0034] 9 is a schematic cross-sectional view of a board-to-board connector 52A according to a modified example. In the board-to-board connector 52A, the second relay connector 54 is of a card edge type, and can be attached and detached by moving the first relay connector 40 inward and outward directions.

[0035] As shown in Figures 2 and 3, the side and top surfaces of the plug retaining cylinder 30 are covered with a first metal shell 32, and the side and top surfaces of the intermediate retainer 46 and the terminal retainer 44 are covered with a second metal shell 34.

[0036] The first shell 32 is flattened and the second shell 34 is rectangular and opens downward. 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 has fixing pieces 32a protruding from both sides for fixing to the board 28. Similarly, the second shell 34 has fixing pieces 34a protruding from both sides for fixing to the board 28. The fixing pieces 32a, 34a are adjacent to each other in the inner and outer directions. The outer fixing piece 32a has a pressing piece 32b that presses down the outer edge of the inner fixing piece 34a from above, so that the fixing piece 34a is stabilized, positioned, and mutual conduction is ensured. The fixing pieces 32a, 34a have screw insertion holes formed therein. The board 28 has screw insertion holes 28c (see FIG. 11) formed at positions corresponding to the fixing pieces 32a, 34a.

[0037] Four studs 56 are erected on the inner side of the operation panel 14b (see also FIG. 1) of the housing 14 at positions corresponding to the fixing pieces 32a, 34a. The tops of the studs 56 are stepped (see FIG. 11), and the small diameter parts 56a fit into the screw insertion holes 28c of the board 28, and the large diameter parts 56b support the rear surface 28b of the board 28. When the screws 58 are screwed into the studs 56, the fixing pieces 32a, 34a and the board 28 are sandwiched and fixed between the heads of the screws 58 and the large diameter parts 56b of the studs 56. In other words, the fixing pieces 32a, 34a of the receptacle connector 26A are fixed to the board 28 via the studs 56 by the screws 58. The fixing pieces 32a, 34a are in contact with the ground of the board 28.

[0038] The inner second shell 34 has three fins 60 that protrude outward at an angle from the top and both side surfaces. The fins 60 elastically contact the top and both side surfaces of the first shell 32 to close the boundary and ensure electrical continuity. The fins 60 may protrude inward from the first shell 32 and contact the second shell 34, but it is more convenient to provide them on the relatively larger second shell 34.

[0039] Receptacle connector 26A is fixed to board 28 by fixing pieces 32a, 34a and first relay connector 40, and basically no soldering is required. Of these, first relay connector 40 is mainly for electrical connection, and fixing pieces 32a, 34a are mainly for mechanical connection. Therefore, no excessive force is applied to first relay connector 40.

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

[0041] In notebook PC 10 and connector / board assembly 12 configured in this manner, receptacle connector 26A and board 28 are detachably coupled with first relay connector 40 on the receptacle connector 26A side and second relay connector 54 on the board 28 side. Therefore, even if receptacle connector 26A is damaged due to the application of an excessive force greater than expected, receptacle connector 26A, which is relatively inexpensive, can be replaced alone, and relatively expensive board 28 can continue to be used as is, thereby reducing the cost burden on the user.

[0042] Moreover, the holder 38 of the receptacle connector 26A includes an electrode holder 42 on the electrode 36a side, a terminal holder 44 on the relay terminal 36b side, and an intermediate holder 46 between them, and the intermediate holder 46 is non-flexible and has volume elasticity. If a flexible sheet were applied to this portion, the shape would not be maintained, and the electrode holder 42 and the terminal holder 44 would essentially become separate bodies, but the non-flexible intermediate holder 46 of this embodiment maintains its shape, so the electrode holder 42, the terminal holder 44, and the intermediate holder 46 become an integrated part, and 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, and by providing the intermediate holder 46, the receptacle connector 26A does not have a special shape, is maintained small, and is almost the same size as the USB Type-C connector according to the conventional technology.

[0043] In the holder 38, the intermediate holder 46 is provided, so that some degree of misalignment in the relative positions of the electrode holder 42 and the terminal holder 44 is tolerated. Even if an excessive force greater than expected is applied to the electrode holder 42 via the plug connector during or after 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] Furthermore, the electrode line 36 has a curved or bent portion at the turn-back portion 36c inside the intermediate holder 46 between the boundary point P1 with the electrode holder 42 and the boundary point P2 with the terminal holder 44, so that even if an external force from 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 turn-back portion 36c can absorb changes in three orthogonal directions and three directions of torsion. Therefore, the terminal holder 44 is hardly affected, 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 approximately the same relative dielectric constant, which makes it possible to suppress transmission loss when a high-speed signal flows through the electrode line 36.

[0046] Receptacle connector 26A has a first shell 32 made of a metal material that covers plug holding cylinder 30 and is fixed to board 28, and a second shell 34 made of a metal material that covers terminal holder 44 and is fixed to board 28, thereby protecting holder 38 and providing an electromagnetic shielding effect. In addition, because first shell 32 and second shell 34 are separate bodies, external forces applied to plug holding cylinder 30 and electrode holder 40 are not transmitted to terminal holder 44.

[0047] The boundary between the first shell 32 and the second shell 34 is sealed by the fin pieces 60 that protrude from one to the other, making it possible to suppress electromagnetic leakage from this boundary.

[0048] The first relay connector 40 and the second relay connector 54 have a floating structure that can absorb the tolerances of each other's relay terminals 36b, 54a, so that even if the force of the electrode holder 42 acts on the terminal holder 44, the force is absorbed by the floating structure and has no effect on the board 28.

[0049] Next, a description will be given of a receptacle connector 26B according to a second embodiment. Regarding receptacle connectors 26B and 26C, components similar to those of receptacle connector 26A described above will be given the same reference numerals, and detailed description thereof will be omitted.

[0050] Fig. 10 is an exploded perspective view of receptacle connector 26B, board 28, and housing 14. Fig. 11 is a view of receptacle connector 26B seen from the outside. Fig. 12 is a perspective view of receptacle connector 26B, board 28, and housing 14 seen from the inside. Screws 58 are omitted in Fig. 12.

[0051] While the above-mentioned receptacle connector 26A is of the so-called top mount type, the receptacle connector 26B is of the so-called mid mount type, which fits into a notch 28d formed in the board 28. In the receptacle connector 26B, the plug holding cylinder 30 fits into the notch 28d, the terminal holder 44 is located above the board 28 as in the above example, and the first relay connector 40 is inserted into and removed from the second relay connector 54 in the vertical direction.

[0052] The receptacle connector 26B has a metal shell 62. The shell 62 corresponds to the above-mentioned shells 32, 34, and has an electromagnetic shielding effect and a fixing effect to the board 28. The shell 62 has a cylindrical portion 62a that covers the periphery of the plug holding cylinder 30, and an inner top plate 62b that is located inside the cylindrical portion 62a. The plug holding cylinder 30 and the cylindrical portion 62a are fixed by claws 30c. The lower halves of the plug holding cylinder 30 and the cylindrical portion 62a fit into the notch 28d.

[0053] The inner top plate 62b is located slightly higher than the cylindrical portion 62a, and the two are connected by a step wall 62c. Bend pieces 62d that are bent downward are provided at both ends of the inner top plate 62b. The inner top plate 62b, the step wall 62c, and the bent pieces 62d cover the terminal holder 44 but are not fixed thereto. Therefore, no external force is transmitted between the plug holding cylindrical body 30 and the terminal holder 44.

[0054] The portions extending from the top surface to the side surfaces on both sides of the tube portion 62a are cut out into a rectangular shape and folded back laterally to form fixing pieces 64R, 64L. In Figures 10 and 11, the right side is fixed piece 64R and the left side is fixed piece 64L. The fixing pieces 64R, 64L correspond to the above-mentioned fixing piece 32a, and the receptacle connector 26B is fixed to the board 28 by the fixing pieces 64R, 64L. The fixing piece 64R has a screw hole through which the screw 58 is inserted, but the fixing piece 64L is not a hole but has a shape that opens to the side.

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

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

[0057] The two fixing pieces 66R, 66L have different heights. Specifically, the right fixing piece 66R is higher than the left fixing piece 66L in the direction perpendicular to the surface of the board 28. The height difference is equal to the plate thickness t of the fixing pieces 66R, 66L, but may be adjusted by a spacer or the like. The left fixing piece 66L of the adjacent right receptacle connector 26C and the right fixing piece 66R of the left receptacle connector 26C overlap with each other and are fixed by a common screw 58 and stud 56. In FIG. 14, the stud 56R (see FIG. 14) supporting the fixing piece 66R of the right receptacle connector 26C 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 board 28.

[0058] The receptacle connector 26C is fixed to the board 28 by the fixing pieces 66R and 66L, not by soldering, so as to be replaceable. When mounting a plurality of receptacle connectors adjacent to each other, the total dimension in the parallel direction can be reduced by overlapping the fixing pieces 66R and 66L. Three or more receptacle connectors 26C may be mounted side by side with the fixing pieces 66R and 66L overlapping, or only one may be mounted. When the receptacle connector 26C is provided with a member equivalent to the second shell 34 in the receptacle connector 26A, 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 FIG. 13 and FIG. 14 is a mid-mount type, but it may also be a top-mount type.

[0059] The present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention. [Explanation of symbols]
