Description

Technical Field

[0001] The present invention relates to a mounting substrate having a socket connector and an electronic device having the mounting substrate. Background Technology

[0002] The mounting base of a notebook PC or tablet PC, etc., has a socket connector on the side surface of the flat-shaped housing, which serves as an I / O connector. The socket connector is often mounted on the edge of the main base plate (see Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-36484

[0004] In recent years, from an ESG (Environmental, Social, and Governance) perspective, products with excellent maintainability are desired for mounting boards like the one described above. From this perspective, easy replacement of the connector is preferred. Especially when the connector conforms to frequently used standards such as USB Type-C, the number of faulty components is high, making easy replacement even more desirable.

[0005] In this respect, the jack connector itself is relatively inexpensive. However, when the jack connector is soldered to the main board, the main board must be replaced to replace the connector. As a result, the cost burden on users increases, and environmental performance is also affected. Summary of the Invention

[0006] The present invention was made in view of the above-mentioned problems in the prior art, and its object is to provide a mounting base and electronic device that allows for easy replacement of the socket connector.

[0007] To address the aforementioned issues and achieve the objective, the first aspect of the present invention relates to a mounting substrate on which components are mounted, comprising: a substrate mounting connector having contacts on its inner surface and a connector connection hole extending along the surface direction of the substrate and opening outwards, mounted on the upper surface of the substrate; a jack connector having a plug retaining body for plug connection, a relay connector detachably connected to the connector connection hole, and a main body having the plug retaining body on the outer side and the relay connector protruding from the inner side; and a guide inclined surface located on the upper side of the substrate near the opening edge of the connector connection hole, gradually moving from the inner side towards the outer side and towards the lower side, wherein the opening edge of the connector connection hole is open in such a way that the relay connector can be inserted within an angle range from the upper outer side to the horizontal, and when the relay connector is inserted from the upper outer side into the opening edge and tilted to the horizontal, the jack connector is guided to the outer side by a portion of the main body slidingly contacting the guide inclined surface.

[0008] The second aspect of the present invention relates to an electronic device having a mounting substrate on which components are mounted, comprising: a substrate mounting connector having contacts on its inner surface and a connector connection hole extending along the surface direction of the substrate and opening outward, mounted on the upper surface of the substrate; a jack connector having a plug connection port for plug connection, a relay connector detachably connected to the connector connection hole, and a body having the plug connection port on the outer side and the relay connector protruding from the inner side; and a guide inclined surface located on the upper side of the substrate near the opening edge of the connector connection hole, gradually moving from the inner side to the outer side and towards the lower side, wherein the opening edge of the connector connection hole is open in such a way that the relay connector can be inserted within an angle range from the upper outer side to the horizontal, and when the relay connector is inserted from the upper outer side into the opening edge and tilted to the horizontal, the jack connector is guided to the outer side by a portion of the body slidingly contacting the guide inclined surface.

[0009] According to the above-described method of the present invention, the socket connector can be easily replaced. Attached Figure Description

Detailed Implementation

[0020] Hereinafter, embodiments of the mounting substrate according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] Figure 1 This is a perspective view of an electronic device 10 according to one embodiment. The electronic device 10 is equipped with a mounting substrate 12 according to one embodiment. The mounting substrate 12 is mounted inside the housing 14 of the electronic device 10. Hereinafter, embodiments of the present invention will be described using an electronic device 10 as a notebook PC as an example. The present invention can also be applied to electronic devices other than notebook PCs, such as desktop PCs or tablet PCs (tablet terminals).

[0022] The electronic device 10 includes a housing 14, a cover 16, and a hinge 18. The housing 14 and the cover 16 are rotatably connected relative to each other via the hinge 18.

[0023] A keyboard device 20 and a touchpad 22 are provided in the housing 14. Inside the housing 14, in addition to the mounting base 12, various electronic components such as a battery device, storage device, speaker, and antenna can be installed. A display device 24 occupying most of the area is provided on the front surface of the cover 16. The display device 24 can be, for example, a liquid crystal display or an organic EL display. Speakers and cameras can also be installed in the cover 16.

[0024] Mounting substrate 12 is supported inside housing 14. Mounting substrate 12 may include a jack connector 26, a substrate mounting connector 27, and a substrate 28. Mounting substrate 12 is a connector / substrate assembly that mounts jack connector 26 to substrate 28 via substrate mounting connector 27.

[0025] Substrate 28 is the main substrate (mother board) in electronic device 10. Substrate 28 is a printed circuit board (PCB). Substrate 28 extends approximately to both ends of the interior of housing 14. Components such as CPU 29, which control the entire electronic device 10, are mounted on substrate 28. Substrate mounting connector 27 is mounted on substrate 28. Socket connector 26 is mounted on substrate 28 via substrate mounting connector 27. Substrate 28, which has substrate mounting connector 27 mounted on it, can also be a substrate different from the main substrate.

[0026] For ease of explanation, around the periphery of the socket connector 26, the side of the housing 14 is considered the outer side, and conversely, the interior of the housing 14 is considered the inner side. Furthermore, using the substrate 28 as a reference, the side where the substrate mounting connector 27 is mounted (upper surface) 28a is considered upper, and the opposite side is considered lower. This upper and lower reference exists in relation to... Figure 1 The housing 14 shown is in the opposite case of top and bottom. That is, if the top and bottom are applied to the housing 14 with reference to the substrate 28, the surface where the keyboard device 20 is provided is sometimes bottom. For the jack connector 26 and the substrate mounting connector 27, the direction orthogonal to the inside-outside direction and the top-bottom direction is taken as the width direction. The above-mentioned directions are used for ease of explanation, and the use of the electronic device 10 is not limited to this. In the substrate 28, most components are mounted on the mounting surface 28a, but some components may also be mounted on the back surface 28b.

[0027] Figure 2 This is a perspective view of the socket connector 26 and the substrate mounting connector 27 obtained from an outside, obliquely upward view. Figure 3 This is a perspective view of the substrate mounting connector 27. Figure 4 This is a 3D view of the jack connector 26. Figure 5 This is a schematic side sectional view of the housing 14 surrounding the jack connector 26, the substrate mounting connector 27, and their periphery. Figure 6 This is a schematic side sectional view showing the state in which the jack connector 26 is mounted on the substrate mounting connector 27.

[0028] First, an example of the structure of the jack connector 26 will be described.

[0029] like Figures 2-6As shown, the jack connector 26 is, for example, a connector compliant with the USB Type C standard. The jack connector 26 can be used for data transfer and charging. The jack connector 26 can also be a connector compliant with the HDMI (registered trademark) standard, etc. The jack connector 26 is mounted to the substrate 28 via the substrate mounting connector 27. Therefore, the jack connector 26 can be mounted and detached from the substrate 28 without soldering.

[0030] The jack connector 26 includes a plug retainer 30, a relay connector 32, a body 33, and a bracket 34. In the jack connector 26, the relay connector 32 connects to a substrate mounting connector 27 mounted on the mounting surface 28a. The jack connector 26 has a crank shape, but this depends on the layout conditions based on the positions of the substrate 28 and the connector hole 55a.

[0031] The main body 33 is made of resin material and has a longitudinal plate 33a, an upper plate 33b, and two triangular plates 33c. The longitudinal plate 33a is located on the outer side of the substrate 28, extending over the top and bottom of the substrate 28. A plug retaining cylinder 30 is provided on the outer side of the lower end of the longitudinal plate 33a. The upper plate 33b is a shorter plate in the inward direction, arranged to extend inward from the upper end of the longitudinal plate 33a. The repeater connector 32 protrudes inward from the upper plate 33b. The width of the repeater connector 32 is slightly smaller than that of the main body 33.

[0032] The triangular plate 33c is a small plate that extends across the longitudinal plate 33a and the upper plate 33b at both ends of the main body 33 in the width direction. The upper plate 33b has a horizontal surface 33ba on the inner half and a gently sloping surface 33bb on the outer half. A guided inclined surface 33ca is formed on the inner lower side of the triangular plate 33c.

[0033] The guided inclined surface 33ca gradually approaches the lower side from the inside towards the outside, with an inclination angle θ of 45 degrees relative to the horizontal. The triangular plate 33c and the relay connector 32 almost do not overlap in the width direction. When viewed from the side (while referring to...), Figure 7 The outer side of the guided inclined surface 33ca reaches the longitudinal plate 33a, and the inner side forms to the inner end (initial abutment portion) 33cb. The inner end 33cb is located at almost the same position as the inner surface of the upper plate 33b. The width dimension of the triangular plate 33c and the guided inclined surface 33ca is, for example, about 2.4 mm. The length of the guided inclined surface 33ca along the inclined direction is, for example, about 2.6 mm.

[0034] The plug retaining cylinder 30 is a metal cylindrical body. The plug retaining cylinder 30 has a flat oval shape with rounded corners. The plug retaining cylinder 30 is located on the outermost side of the socket connector 26, and is positioned lower than the repeater connector 32.

[0035] A connector hole 55a is formed on the vertical wall 55 forming the side surface of the housing 14 (see also...). Figure 1 The plug retaining cylinder 30 is positioned opposite the connector hole 55a. Thus, the plug connection port 30a of the plug retaining cylinder 30 protrudes outwards from the housing 14 through the connector hole 55a. The plug connection port 30a allows the plug 36 to be inserted and connected (see reference). Figure 5 Plug 36 is a connector for cables and devices. The connection standard between plug port 30a and plug 36 conforms to, for example, the USB Type C standard. Plug 36 can be inserted into and connected to plug port 30a regardless of its orientation. The lower half of plug port 30a is slightly angled.

[0036] A tongue-shaped plate 38 is provided inside the plug retainer housing 30. Contacts 38a and 38b are respectively provided on the lower and upper surfaces of the plate 38. Each contact 38a and 38b provides contact with the terminals of the plug 36. Contacts 38a and 38b are each composed of multiple metal pins arranged in the width direction of the plate 38. Each contact 38a and 38b is connected to terminals 41 and 42 of the relay connector 32 via electrode wires through the body 33. For example, contacts 38a and 38b and terminals 41 and 42 each have 24 metal pins.

[0037] The repeater connector 32 is located at the innermost side of the jack connector 26. The repeater connector 32 is located on the mounting surface 28a. The repeater connector 32 may have a plug structure. The repeater connector 32 can be detachably connected to the connector connection hole 46 of the substrate mounting connector 27.

[0038] The repeater connector 32 may have: a tongue-shaped plate 40, a first terminal 41 disposed on the lower surface 40a of the plate 40, and a second terminal 42 disposed on the upper surface 40b of the plate 40. The terminals 41 and 42 are, for example, composed of a plurality of metal pins arranged in the width direction of the plate 40. The terminals 41 and 42, for example, each have 12 metal pins.

[0039] The bracket 34 is a thin sheet metal component. The bracket 34 covers the outer peripheral surface of the plug retaining cylinder 30, excluding the plug connection port 30a, the outer surface of the longitudinal plate 33a, and the upper surface of the upper plate 33b. The bracket 34 has a pair of retaining plates 34a and 34b in the width direction. Each retaining plate 34a and 34b protrudes from the side surface of the plug retaining cylinder 30 in opposite directions. The retaining plates 34a and 34b are used to fix the socket connector 26 relative to the base plate 28. Screw through holes are formed in each retaining plate 34a and 34b. The heights of the retaining plates 34a and 34b are slightly different, such as... Figure 2When multiple socket connectors 26 are arranged adjacently as shown by the imaginary lines, space can be effectively utilized by overlapping one fixing piece 34a with another fixing piece 34b. A fin 34c protrudes obliquely downwards and inwards from the fixing pieces 34a and 34b. A cutout 28c is formed in the substrate 28 to avoid the fin 34c (see reference). Figure 2 The bracket 34 has a pair of claws 34d in the width direction. The claws 34d hold the side surfaces of the upper plate 33b and the triangular plate 33c.

[0040] A stud 60 is formed on the plate portion 54 forming the inner surface of the housing 14 (see reference). Figure 5 An internal thread is formed in the opening on the top surface of the stud (fixing part) 60. The screw 35 of the screw 35, which is screwed into the screw insertion hole of each fixing piece 34a, 34b, is screwed into the internal thread of the stud 60. Thus, the socket connector 26 is fixed to the housing 14 with the relay connector 32 in a horizontal orientation.

[0041] Next, an example of the structure of the substrate mounting connector 27 will be described.

[0042] like Figures 2-6 As shown, the substrate mounting connector 27 can be fixed and mounted on the mounting surface 28a of the substrate 28 by soldering the connecting surface 27a. The substrate mounting connector 27 can be detachably connected to the relay connector 32 of the jack connector 26. In this embodiment, the relay connector 32 has a plug structure, therefore the substrate mounting connector 27 has a socket structure.

[0043] The substrate mounting connector 27 has a connector connection hole 46. The connector connection hole 46 extends along the surface direction of the substrate 28 and opens outward. The opening edge of the connector connection hole 46 has a first edge 48a and a second edge 49a. The first edge 48a is the edge on the side (lower side) of the mounting surface 28a. The second edge 49a is the edge on the side (upper side) opposite to the mounting surface 28a. The edges 48a and 49a extend along the width direction of the connector connection hole 46.

[0044] Terminals 51 and 52 are provided on the inner surface of the connector connection hole 46. Terminals 51 and 52 contact terminals 41 and 42 of the relay connector 32 respectively, and are electrically connected to each other. Either the combination of the lower terminal 51 and terminal 41, or the combination of the upper terminal 52 and terminal 42, can be omitted. The substrate mounting connector 27 and the relay connector 32 can also be electrically connected between the inner surface 46a and the front surface 32a via elastic contacts.

[0045] The inner surface of the connector connection hole 46 has a first inner surface 48 and a second inner surface 49. The first inner surface 48 corresponds to the lower surface of the connector connection hole 46. The first inner surface 48 extends inward from a first edge 48a in the inward-outward direction of the connector connection hole 46. The second inner surface 49 corresponds to the upper surface of the connector connection hole 46. The second inner surface 49 extends inward from a second edge 49a in the inward-outward direction of the connector connection hole 46.

[0046] The first terminal 51 is configured as a lower contact 51a exposed on the first inner surface 48. The second terminal 52 is configured as an upper contact 52a exposed on the second inner surface 49. The terminals 41 and 42 of the repeater connector 32 contact and conduct with the respective contacts 51a and 52a of the terminals 51 and 52, respectively. Each terminal 51 and 52 is connected to a signal line or ground pattern formed on the substrate 28. The terminals 51 and 52 are each composed of a plurality of metal pins arranged in the width direction of the connector connection hole 46. For example, each terminal 51 and 52 has 12 metal pins.

[0047] like Figure 5 As shown, in the inward and outward directions of the connector connection hole 46, the second edge 49a is offset further inward than the first edge 48a. Conversely, in the inward and outward directions of the connector connection hole 46, the first edge 48a is offset further outward than the second edge 49a. Therefore, in the connector connection hole 46, the first edge 48a, which becomes the lower jaw, protrudes further outward than the second edge 49a, which becomes the upper jaw. As a result, the opening edge of the connector connection hole 46 forms an open space S1 that is open at the top. The open space S1 is a space that allows the root portion of the relay connector 32, which has been inserted into the connector connection hole 46, to swing up and down.

[0048] An inclined surface 49b is formed on the second edge 49a facing the open space S1. The inclined surface 49b gradually slopes upwards from the inside of the connector connection hole 46 toward the outside, away from the mounting surface 28a. The inclination angle of the inclined surface 49b relative to the surface direction of the substrate 28 is not limited, and can be set to about 30 to 40 degrees with a horizontal reference. The inclination angle in this embodiment is about 30 degrees. The inclination angle of the inclined surface 49b can be designed taking into account the standing height of the vertical wall 55 (described later) and the vertical height of the socket connector 26.

[0049] The connector connection hole 46 can have an expansion space S2 formed by recessing the portion of the first inner surface 48 that is inside the first contact 51a toward the mounting surface 28a (downward). The expansion space S2 is a space formed by extending the inner part of the connector connection hole 46 downward. The expansion space S2 is a space that allows the front end portion of the repeater connector 32, which has been inserted into the connector connection hole 46, to swing downward.

[0050] At the opening edge of the connector connection hole 46, a lower inner surface 48 forms an inner lower surface end portion 48b, and a second inner surface 49 forms an outer upper surface end portion 49c. The outer upper surface end portion 49c corresponds to the lower end of the inclined surface 49b. The lower inner surface end portion 48b and the outer upper surface end portion 49c are close to each other, but in the inward and outward direction, the outer upper surface end portion 49c is offset further inward than the lower inner surface end portion 48b, allowing the repeater connector 32 to be inserted at an angle (see reference). Figure 5 Additionally, the relay connector 32, which is inserted at an angle into the opening edge of the connector connection hole 46, can be manually tilted and moved to a horizontal position (see reference). Figure 8 That is, the opening edge of the connector connection hole 46 is open in such a way that the relay connector 32 can be inserted from the upper outer angle to the horizontal.

[0051] The lower contact 51a is located near the inner end 48b of the lower surface and contacts the terminal 41 via the springiness of the terminal 51, thus allowing for slight elastic displacement in the downward direction. The lower contact 51a and the inner end 48b of the lower surface are sufficiently close to each other and are collectively referred to as the lower reference point C1 (see reference). Figure 7 The upper contact 52a is located near the outer end 49c of the upper surface and is in contact with the terminal 42 by the springiness of the terminal 52, thus allowing for a slight elastic displacement in the upward direction. The upper contact 52a and the outer end 49c of the upper surface are sufficiently close to each other and are also referred to as the upper reference point C2 (see reference). Figure 7 The lower reference point C1 and the upper reference point C2 are in general contact with the tilted relay connector 32 (see reference). Figure 8 ).

[0052] The substrate mounting connector 27 has a metal housing 61 covering its upper and side surfaces. The metal housing 61 has: side plates 61a on both sides, two feet 61b protruding downwards from each side plate 61a, and protrusions 61c protruding outwards from each side plate 61a. The feet 61b are inserted into and soldered to through holes in the substrate 28, are reliably fixed, and are connected to ground. That is, the metal housing 61 provides a shielding effect. The front end of the protrusion 61c is arrow-shaped. The metal housing 61 is stable because the four feet 61b are fixed to the substrate, thereby stabilizing the protrusions 61c. Each protrusion 61c is equipped with a tilting platform 62 having a guiding tilting surface 62a. The tilting platforms 62 mounted on the protrusions 61c are positioned on the upper side of the substrate 28 near the opening edge in the connector connection hole 46.

[0053] The tilting stage 62 is made of resin material and is approximately a right-angled triangle when viewed from the side. A guide tilting surface 62a is formed on the outer and upper sides. The tilting stage 62 is stabilized by its lower surface abutting against the mounting surface 28a of the substrate 28 and its inner surface abutting against the edge of the side plate 61a. Holes for inserting protrusions 61c are formed on the inner surface of the tilting stage 62. The tilting stage 62 is symmetrical and well-balanced in the width direction with respect to the protrusions 61c as the center. The guide tilting surface 62a gradually approaches the lower side from the inner side towards the outer side, with a tilt angle θ of 45 degrees relative to the horizontal. That is, the tilt angles of the guide tilting surface 62a and the guided tilting surface 33ca are equal. The edges of the two guide tilting surfaces 62a on their closest sides are chamfered.

[0054] The height of the tilting stage 62 is approximately equal to the height of the metal housing 61 from the mounting surface 28a. The width of the tilting stage 62 in both the inward and outward directions is approximately equal to its height. Furthermore, the width dimension of the metal housing 61 is approximately equal to that of the plug retaining cylinder 30, eliminating the need for additional enlargement for mounting the tilting stage 62. The width dimension of the tilting stage 62 is relatively small, for example, around 2.0 mm, ensuring it will not interfere with the fins 34c. The substrate mounting connector 27 has a downwardly projecting locating pin 63 (see reference). Figure 6 The positioning pin 63 is inserted into the positioning hole formed on the substrate 28 and positioned.

[0055] like Figure 5 As shown, the housing 14 may include: a housing component 56 having a plate portion 54 and a vertical wall 55, and a cover component 58.

[0056] The housing component 56 can have a shallow bathtub shape by forming a vertical wall 55 on the outer periphery of the plate portion 54. The plate portion 54 forms the operating surface 14a of the housing 14. The operating surface 14a is the surface that exposes the keyboard device 20 and the touchpad 22 (see reference). Figure 1 A stud 60 can be formed on the inner surface 54a of the plate portion 54. The stud 60 is disposed at least in positions corresponding to the two retaining tabs 34a, 34b. As described above, the stud 60 can be used to fasten the socket connector 26. The portion of the base plate 28 other than the periphery of the socket connector 26 is also suitably supported on the inner surface 54a of the plate portion 54.

[0057] The upright wall 55 rises upward from the outer periphery of the plate portion 54. A connector hole 55a is formed in the upright wall 55 forming the side surface of the housing 14 (see also...). Figure 1 Connector hole 55a is opposite to plug connection port 30a of socket connector 26. Connector hole 55a is an opening for connecting plug 36 to plug connection port 30a.

[0058] The cover member 58 is a plate-shaped member that blocks the opening of the housing member 56. A tapered portion 58a can be provided at the edge of the cover member 58. The tapered portion 58a slopes inward from the front end (upper end 55b) of the vertical wall 55. The jack connector 26 can be configured to allow the upper and lower steps of the plug retaining cylinder 30 to bypass the inner surface of the tapered portion 58a.

[0059] like Figure 5 As shown, the jack connector 26 can be mounted on the substrate 28 via the substrate mounting connector 27 and supported on the housing 14 via the retaining plates 34a, 34b and the stud 60. The jack connector 26 can also be threaded onto the substrate 28 at a location other than the retaining plates 34a, 34b. In this state, a predetermined gap G can be provided between the opening end 30b of the plug connection port 30a and the inner surface of the vertical wall 55. The gap G is the opposing distance between the vertical wall 55 and the plug connection port 30a. The gap G can be, for example, set to 0.2 mm. The gap G can also be approximately zero.

[0060] Next, the installation action and effect of the socket connector 26 will be explained.

Figure 8 (b) is a diagram showing the state of relay connector 32 at 20 degrees during the intermediate stage. Figure 8 (c) is a diagram showing the state of repeater connector 32 at 10 degrees during the intermediate stage. Figure 8 (d) is a diagram showing the state of relay connector 32 at 0 degrees in the final stage. Figure 8 (a) corresponds to Figure 6 and Figure 7 , Figure 8 (d) corresponds to Figure 5 . Figure 8 Points P1 to P4 are reference points for the operation of the socket connector 26, and are set on the extension of the plate 38 at the plug connection port 30a.

[0062] When mounting the jack connector 26 relative to the substrate mounting connector 27, firstly, the cover member 58 is removed from the housing member 56. This exposes the interior of the housing 14. Then, as... Figure 6 , Figure 7 As shown, the relay connector 32 is inserted into the connector connection hole 46 from the opening edge.

[0063] The repeater connector 32 is inserted approximately along the inclined surface 49b into the depth of the expansion space S2 until the inner end 33cb of the guided inclined surface 33ca abuts against the upper part of the guided inclined surface 62a. The inner end 33cb abuts against the guided inclined surface first. At this time, the front end surface 32a reaches near the intersection of the inner surface 46a and the mounting surface 28a. The lower surface 40a of the plate 40 constituting the repeater connector 32 has almost no gap or contact with the lower reference point C1, and the upper surface 40b has almost no gap or contact with the upper reference point C2. Normally, the plate 40 contacts at least one of the lower reference point C1 and the upper reference point C2. In addition, the lower contact 51a of the lower reference point C1 and the upper contact 52a of the upper reference point C2 can elastically contact the plate 40. The inner end 33cb is the initial abutment portion relative to the guided inclined surface 62a and functions as a limiter restricting the insertion depth of the repeater connector 32. The inner end 33cb serves as the operating reference in at least the initial stage of the installation action of the socket connector 26, and is therefore referred to as the operating reference point C0.

[0064] Additionally, at this time, the upper plate 33b is located outside and above the action reference point C0, and the horizontal surface 33ba and the gently inclined surface 33bb become easily accessible for manual operation, serving as the pressing operation surface. However, in this embodiment, the horizontal surface 33ba and the gently inclined surface 33bb are covered by the bracket 34, so it is actually the bracket 34 that is touched by the human hand. The horizontal surface 33ba is at approximately 30 degrees, the same as the relay connector 32, and the gently inclined surface 33bb is at approximately 20 degrees.

[0065] Then, as Figure 7 , Figure 8 As shown in (a), if the horizontal surface 33ba and the gently inclined surface 33bb, which serve as the pressing operation surface, are manually pressed, a downward force is applied outward as indicated by arrow A1 due to the inclination of these surfaces. The operating reference point C0 slides into contact with the guide inclined surface 62a and is guided to the lower side. In addition, since the pressing operation surface is located outside and above the operating reference point C0, a rotational force centered on the operating reference point C0 is also applied to the socket connector 26 as indicated by arc arrow A2.

[0066] As described above, the tilt angle θ of the guide tilt surface 62a is 45 degrees, which is suitable for guiding the motion reference point C0 to slide contact. The range of the tilt angle θ of the guide tilt surface 62a suitable for guiding the motion reference point C0 to slide contact downward is approximately 45 degrees to 60 degrees from the horizontal reference.

[0067] As the jack connector 26 is displaced, at least one of the lower contact 51a, the inner end of the lower surface 48b constituting the lower reference point C1, and the upper contact 52a, the outer end of the upper surface 49c constituting the upper reference point C2, abuts and slides against the plate 40, thereby assisting the jack connector 26 to move while rotating rather than moving in parallel.

[0068] Thus, as Figure 8 As shown in (b), the socket connector 26 is displaced diagonally downward and rotated as a whole. At this moment, the relay connector 32 and the horizontal plane 33ba are about 20 degrees apart, and the gently inclined plane 33bb is about 10 degrees apart.

[0069] like Figure 8 As shown in (c), if the socket connector 26 is further displaced diagonally downwards, it will rotate as a whole. At this time, the relay connector 32 and the horizontal plane 33ba are about 10 degrees apart, and the gently inclined plane 33bb is about 0 degrees apart.

[0070] like Figure 8 As shown in (d), if the socket connector 26 is further displaced downwards, it rotates as a whole. At this moment, the relay connector 32 and the horizontal plane 33ba are at 0 degrees (i.e., horizontal), and the gently inclined plane 33bb is at approximately -10 degrees. The relay connector 32 becomes horizontal, thereby the lower contact 51a makes elastic contact with the terminal 41, and the upper contact 52a makes elastic contact with the terminal 42, and they are respectively connected. In addition, the guided inclined plane 33ca is stable in contact with the guiding inclined plane 62a. The guided inclined plane 33ca can also slide into contact with the guiding inclined plane 62a from the middle stage. That is, the guided inclined plane 33ca is in contact with the guiding inclined plane 62a during the period until the relay connector 32 becomes horizontal. The fixing plates 34a and 34b are respectively mounted on the studs 60 and fixed by the screws 35, and the plug connection port 30a of the plug retaining cylinder 30 is opposite to the connector hole 55a.

[0071] Figure 8 In (a), the plug retains the front end of the cylinder 30 at point P1. Figure 8 Move to point P2 in (b), and in Figure 8 Move to point P3 in (c), and in Figure 8 The device moves to point P4 in (d), thus tracing trajectory T1. Point P4 in the final stage is extremely close to wall 55, but the initial point P1 is slightly closer to the inside of wall 55. Therefore, the intermediate points P2 and P3 are roughly located on the gentle arc connecting P1 to P4 and will not interfere with wall 55. Assuming the socket connector 26 is in the final stage... Figure 8If the mechanism with the reference point C0 in (d) is a center-rotating mechanism, it will interfere with the vertical wall 55 as shown in trajectory T2. Therefore, it can be considered that complex steps and mechanisms are needed to avoid this situation. In contrast, in this embodiment, the socket connector 26 can be configured and installed in the appropriate position without interference by pressing the pressing operation surface only once.

[0072] Press the horizontal surface 33ba and the gently inclined surface 33bb of the operating surface. Figure 8 The initial stage of (a) is located above and outside the action reference point C0, making it easy to press, tilting upwards and outwards, making it easy to apply force in the appropriate direction. Additionally, until... Figure 8 The final stage of (d) becomes horizontal, making the operation easy to understand intuitively.

[0073] This concludes the description of an example of mounting the jack connector 26 onto the substrate mounting connector 27. However, the reverse steps can be performed, for example, when removing and replacing a faulty jack connector 26. Of course, the jack connector 26 will not interfere with the vertical wall 55 when it is removed.

[0074] When removing the jack connector 26, first remove the screws 35 from the retaining plates 34a and 34b fixed to the studs 60. This causes the plate 40 to be spring-loaded from the contacts 51a and 52a at positions offset vertically and horizontally, thereby generating a small clockwise rotational force. Consequently, the jack connector 26 automatically rotates slightly, and the plug retainer 30 pops out in a lifted manner, making it easy to pinch. Thus, according to this embodiment, the jack connector 26 can be easily replaced. Furthermore, since the substrate 28 itself does not need to be replaced to replace the jack connector 26, the user's cost burden is reduced, and environmental performance is improved.

[0075] This invention is not limited to the above-described embodiments, and can of course be freely modified within the scope of the spirit of this invention.
