Description

Strengthening member and electronic device having the same

The present invention generally relates to a reinforcing member, and more particularly, to a reinforcing member for reinforcing and fixing a connector and an electronic apparatus having the same. Here, “electronic device” means, for example, a notebook personal computer (hereinafter referred to as “PC”), a personal digital display, etc.

The concept includes Ruasistan (PDA), electronic dictionary, electronic stationery, game machine, and the like.

Thread 1

The reinforcing member of the present invention is, for example, a notebook personal computer (hereinafter referred to as “PC”).

That's it. It is suitable for a metal fitting for reinforcing and fixing a connector to which a mouse or the like is connected.

Technical background

In recent years, notebook PCs are small and light for convenience of carrying, and desktops such as offices are required to exhibit the same rich functions as desktop PCs. For this reason, the notebook PC is equipped with only the functions necessary for operation, and each part is reduced in size and weight by reducing the number of parts by making it multifunctional. On the other hand, in order to achieve high functionality, peripheral devices such as a mouse, keyboard, AC adapter, and USB device can be connected to the laptop PC connector as needed. Some connectors on notebook PCs have high connection stability and relatively low connections. As the former connector, for example, there is a printer connector in which both ends are fixed with hexagon bolts and connected to a printer. Examples of the latter connector include a connector used for connection with an external device that is frequently inserted and removed by a user, such as a mouse, a keyboard, an AC adapter, and a USB device.

Since the connection between bolts and nuts is unnecessary, the latter connector has the advantage that it can be easily attached and detached. However, since the load is applied when an external device is attached / detached or used, the latter connector is easily damaged, and the expected product life may not be achieved. Therefore, in order to solve such a problem, a reinforcing member that captures and fixes the connector inside the casing of the notebook PC has been proposed. FIG. 8 is a partially enlarged exploded perspective view of the frame 20, the mother board 30, and the metal fitting 40 of the conventional notebook PC 10. The laptop PC 10 is connected to a PC main body 12 with a keyboard (not shown) and a liquid crystal display (LCD) (not shown) by a hinge mechanism (not shown). Figure 8 shows the internal structure of the PC main body 12. It shows. In the figure, H is the hinge side of PC body 12. The mother board 30 is mounted with a mouse PS / 2 connector 32 having a substantially rectangular parallelepiped shape. A mouse (not shown) is attached to the connector 32 in the direction of arrow M via a cable. The mouse PS / 2 connector 3 2 is a mouse / keyboard connector that can also be connected to a keyboard.

If this happens, an external force may be applied to the connector 32 by the user or cable when the mouse is attached or detached or used. In particular, the connector 32 is often provided on the back of a notebook PC, and the user often attaches and detaches the mouse by groping from the front. For this reason, a force different from the intended direction is often applied to the connector 3 2. Therefore, in order to solve such a problem, the metal fitting 40 is fixed to the frame 20 with screws 14 and screw holes 2 2 and 42 to cover the connector 3 2, and the connector 3 2 is reinforced. Fix it.

The metal fitting 40 has a U-shaped cross section that fits the outer shape of the connector 32, and has a protrusion 44 at the center of the upper part. Also, the frame 20 has 2 4 even on the front and top surfaces of the connector 3 2. The presser 2 4 includes a front presser standing upright on the surface on the hinge side H and a top plate presser bent at a right angle from the front presser. The connector 3 2 has a substantially circular connecting portion (not shown) on the hinge side H, but the front retainer 24 has a circular hole (not shown) that exposes only the connecting portion, and the circular connecting portion of the connector 3 2. And the rectangular outer shape can contact the connector 3 2.

The connector 3 2 is restricted from moving in the X-axis direction by fixing in the screw holes 2 2 and 4 2 between the bracket 40 and the frame 20, and the front pressing 2 4 of the frame 20 and the protrusion 4 of the bracket 40 The movement in the Y-axis direction is restricted by 4, and the movement in the Z-axis direction is restricted by the top board holder 2 4 of the mother board 30 and frame 20. As described above, the metal fitting 40 is configured to catch and fix the connector 32 by restricting the movement of the connector 32 in the three axial directions. Furthermore, the metal fitting 40 is provided with a grounding function in order to reduce the number of parts due to the multi-function. The notebook PC further has an antenna for wireless LAN, a connector for connecting a telephone line jack for a modem, and a cable 60 for connecting the antenna for bluetooth and the motherboard 30. The wireless LAN antenna is installed at the top of the LCD to improve the antenna characteristics, and the cable 60 is connected to the antenna via a hinge mechanism. A spacer 50 made of a rectangular parallelepiped sponge (foam material) or the like is fixed to the mother board 30 with double-sided tape. In FIG. 8, the bracket 40, the spacer 50 and the cable 60 are expanded. As shown in FIG. 9, the end surface 51 of the spacer 50 is It is fixed by pressing against the front 4 of 1. In the foam material 50, a conductive double-sided tape 52 is attached to the hatched portion in FIG. 8, and the conductive tape 52 extends to the end surface 51. The cable 60 is provided with a conductive coating 62. When the conductive coating 62 is adhered to the conductive tape 52, the cable 60 is electrically connected to the frame 20 through the metal fitting 40 and is grounded by the frame 20. As a result, electrostatic discharge (ESD), electromagnetic interference (EMI), and wireless communication characteristics of the cable 60 are improved. Here, FIG. 9 is a partially enlarged perspective view showing the assembled state of FIG.

As another conventional technique, for example, there is Patent Document 1.

Patent Literature 1

Japanese Utility Model Publication No. 6 0-8 8 4 7 7 Disclosure of Invention

The present inventor has found that the conventional metal fitting 40 does not necessarily have a sufficient reinforcing function of the connector 32. That is, in FIG. 8, the connector 32 is not protected from rotation around the Y axis and rotation around the Z axis. In addition, there is a gap between the top plate holder 24 and the upper surface of the connector 32. This gap is intended to absorb manufacturing errors, but for this reason, the slight movement of the connector 32 in the Z-axis direction and the rotation around the X-axis are not completely restricted. As a result, the connector 32 is not sufficiently protected against external forces acting in these directions and may be damaged. Further, the present inventor has found that the conventional grounding mechanism of the metal fitting 40 requires a spacer 50 and the assembly work is complicated, and that the multi-function of the metal fitting 40 has room for improvement. discovered. In this regard, it is conceivable to attach the cable 60 directly to the metal fitting 40. However, Fig. 8 shows only one cable 60, but in reality, multiple cables are prepared (for example, two cables connected to the antenna for wireless LAN). 1 cable as a cable to be connected to the telephone line jack connector for the modem, and 1 cable as a cable to be connected to the antenna for the bluetooth). It is difficult to bond 6 2 directly.

Accordingly, an object of the present invention is to provide a reinforcing member and an electronic device having the reinforcing member that preferably reinforces and fixes the connector more than before while realizing multi-functionality.

A reinforcing member according to one aspect of the present invention is a reinforcing member for reinforcing and fixing the connector of an electronic device having a board on which a connector to which an external device can be connected along a first axis is mounted. A first restricting portion for restricting rotation of the connector around a substrate and a second axis perpendicular to the first axis; and a second restriction for restricting rotation of the connector around the first axis And a third restricting portion that abuts against the connector and restricts movement of the connector along the second axis. The first restricting part restricts the rotation of the connector around the Z axis in FIG. 8, and the second restricting part restricts the rotation of the connector around the Y axis in FIG. The third restrictor restricts movement of the connector in the Z-axis direction, but unlike the top plate retainer 24 in Fig. 8, the connector makes contact with the connector, making it less likely to move in the Z-axis direction than before. ing. Therefore, the reinforcing member catches and fixes the connector in the direction where the catching force has been insufficient in the past. The strong member is formed, for example, by bending a sheet metal or the like. Thus, the reinforcing member can be easily configured without using a plurality of members.

The connector includes, for example, a front surface that is perpendicular to the first axis and connected to the external device, a rear surface that is perpendicular to the first axis and that faces the front surface, and that is horizontal to the substrate and to the second axis. An approximately upper surface having a vertical top surface and a pair of side surfaces perpendicular to the front surface, the back surface, and the top surface; A rectangular parallelepiped shape, and the reinforcing member includes a front surface portion parallel to the rear surface of the connector and having the first restriction portion, a pair of side surface portions parallel to the pair of side surfaces of the connector, and the connector. An upper surface portion that is inserted between a frame of an electronic device that is coupled to the substrate and protects the substrate in parallel with the upper surface and the upper surface of the connector, and functions as the third restricting portion; and A pair of first projecting portions extending parallel to the upper surface portion of the reinforcing member from each of the pair of side surface portions and fixed to the frame; and the reinforcing member from each of the pair of side surface portions of the reinforcing member A second projecting portion extending in parallel with the front surface portion and having the second restricting portion.

A reinforcing member according to another aspect of the present invention is a reinforcing member for reinforcing and fixing the connector of an electronic device having a board on which a connector to which an external device can be connected along the first axis is mounted. And a restricting portion for restricting rotation about a second axis perpendicular to the substrate and the first axis. Since the restricting part restricts the rotation of the connector around the Z-axis in FIG. 8, such a reinforcing member reinforces and fixes the connector in a direction in which reinforcement has been insufficient in the past. Preferably, the restricting part restricts movement of the connector along the first axis. As a result, the restricting portion restricts the movement of the connector in the Y-axis direction in FIG. 8, so that the reinforcing member can be multi-functional. The restricting portions are, for example, a pair of abutting portions that abut against a surface of the connector facing a surface to which the external device is connected.

A reinforcing member according to another aspect of the present invention is a reinforcing member for reinforcing and fixing the connector of an electronic device having a board on which a connector to which an external device can be connected along the first axis is mounted. And a restricting portion for restricting rotation of the connector around the first axis. Since the restricting part restricts the rotation of the connector around the Y axis in Fig. 8, such a reinforcing member reinforces and fixes the connector in the direction where the reinforcement has been insufficient in the past. It is preferable that the restricting portion restricts movement of the connector along the first axis and a third axis perpendicular to the substrate and the second axis perpendicular to the first axis. As a result, the restricting portion restricts the movement of the connector in the X-axis direction in FIG. 8, so that the multi-function of the reinforcing member can be achieved. The electronic device includes a frame having a pair of engaging portions on both sides of the connector on a surface perpendicular to the first axis, coupled to the substrate to protect the substrate, For example, before It is a pair of engaging part engaged with the engaging part of a recording frame.

• The reinforcing member according to another aspect of the present invention is a reinforcing member for reinforcing and fixing the connector of an electronic device having a board on which a connector to which an external device can be connected along the first axis is mounted. And a restricting portion for restricting movement of the connector along a second axis perpendicular to the substrate and the first axis in contact with the connector. The restricting part restricts the movement of the connector in the Z-axis direction in Fig. 8, but unlike the top plate retainer 24 in Fig. 8, the connector is less likely to move in the Z-axis direction than the conventional because it contacts the connector. It is summer. Such a reinforcing member reinforces and fixes the connector in a direction in which reinforcement has been insufficient. Preferably, the restricting portion restricts rotation of the connector around the first axis and a third axis perpendicular to the substrate and the second axis perpendicular to the first axis. As a result, the restricting portion restricts the rotation of the connector in the X-axis direction in FIG. 8, so that the reinforcing member can be multi-functional. The restricting portion is, for example, a top plate presser that is inserted between a connector that is coupled to the substrate included in the electronic device and protects the substrate and the connector and that suppresses the surface of the connector parallel to the substrate.

A reinforcing member as still another aspect of the present invention includes a board on which a connector to which an external device can be connected along the first axis is mounted, and a frame that is coupled to the board and protects the board. A reinforcing member for reinforcing and fixing the connector of the electronic device, wherein the frame and the reinforcing member are made of a conductive member, and are in contact with a conductive portion of a cable connected to the substrate, and the cable is connected to the frame. And a holding part for grounding the cable. In this reinforcing member, since the holding portion has the function of the spacer in FIG. 8, the number of parts can be reduced by making the reinforcing member multifunctional. In addition, such a strength member is not affected by a decrease in the adhesive strength of the tape 52, and is a stable contact between the conductive parts, so that the performance of the ground is higher than that through the spacer 50. improves.

A reinforcing member as still another aspect of the present invention is a reinforcing member for reinforcing and fixing the connector of an electronic device having a board on which a connector to which an external device can be connected along the first axis is mounted. Holding the cable in contact with the conductive portion of the cable connected to the substrate, defining the route of the cable, and separating the cable from the substrate It has the part. Such a reinforcing member can maintain predetermined electrical characteristics or communication characteristics in order to separate the cable from the board so that the holding portion is not affected by noise from the board.

The holding portion includes, for example, first and second projecting portions that extend at different heights along the first axis to the opposite side of the connector, and the conductive portion of the cable includes the first and second protrusions. It is held by the holding part by being sandwiched between the second projecting parts.

An electronic device according to another aspect of the present invention includes a board on which a connector that allows an external device to be electrically connected along the first axis is mounted, and a frame that engages with the board and protects the board And the above-described reinforcing member for reinforcing and fixing the connector. Since the reinforcing member reinforces and fixes the connector, an electronic device (for example, a notebook PC) can maintain the expected life of the connector. The connector is, for example, a mouse, a keyboard, a USB device, a connector for an AC adapter, or a connector for a video (S—OU).

Hereinafter, an electronic device 100 according to the present invention embodied as a notebook PC will be described with reference to the accompanying drawings. Here, FIG. 1 is a front perspective view of the notebook PC 100, and FIG. 2 is a rear perspective view of the notebook PC 100. FIG. Referring to FIG. 1 and FIG. 2, the electronic device 100 is illustratively embodied as a notebook PC 100, but is not limited to this, and is not limited to this. It includes portable electronic devices such as personal computers, palm-sized personal computers, wearable computers, electronic dictionaries, electronic stationery, game consoles, and portable home appliances (for example, portable TVs, portable video decks, and portable DVDs). In addition, the size of the notebook type 卩 0100 covers 4 sizes, B 5 sizes, other notebook sizes, mini-note sizes and so on.

The notebook PC 100 has a liquid crystal display (LCD) bezel frame (upper housing) 110, a hinge mechanism 120, and a base (lower housing) 130 as a PC main body.

L CD bezel frame 1 1 0 includes an LCD screen 1 1 2 and a cover 1 1 4 that sandwiches the LCD screen 1 1 2 and is a wireless LAN compliant with IEEE 802.1 1 ab Z g etc. For example, the antenna for Bluetooth and the antenna for Bluetooth are built in part A in Fig. 1. In addition, a connector for connecting a telephone line jack is mounted on the base 130 for the modem. The cover 1 1 4 is formed by resin molding, but if necessary, it may be formed by extrusion molding of aluminum or magnesium to improve the electromagnetic shielding effect and strength.

The hinge portion 120 connects the L CD bezel frame 110 and the base 130 so that they can be freely opened and closed, and can maintain the L CD bezel frame 110 with respect to the base 130 at a predetermined angle.

Base 1 30 consists of a casing 1 3 2 consisting of vertical force pars and a keyboard for information types 1 34 and pointing device 1 3 6. As shown in FIG. 3, the base 130 contains a circuit board (mother board) 140, a frame 150, a metal fitting 200, and various units (for example, HDD). Here, FIG. 3 is an exploded perspective view showing the circuit board 140, the frame 150 and the metal fitting 200. However, some components such as the heat dissipation fan are omitted in Fig. 3. Since any structure known in the art can be applied to the housing 1 3 2, the keyboard 1 34, and the pointing device 1 36, description thereof is omitted here.

In addition to mounting various electronic components such as the CPU 14 1, the circuit board 1 4 0 is mounted with a number of connectors to which external devices can be connected. For example, as shown in FIG. 2 and FIG. 3, the connector 14 2 is a PS / 2 connector to which a mouse 102 is connected, and the connector 144 is a printer connector to which a printer is connected. Unlike the connector 14 3 whose both ends are fixed with hexagonal bolts, the connector 144 is not provided with a fixing member, so that a metal fitting 200 is provided to reinforce and fix the connector 144. This PS / 2 connector for mouse is a mouse / keyboard connector that can also be connected to a keyboard. -The connector 1 4 2 has a substantially rectangular parallelepiped structure having a front surface 1 42 a, a rear surface 1 42 b, an upper surface 1 42 c, and a pair of side surfaces 1 42 d. The front surface 14 2 a is a surface perpendicular to the Y-axis direction shown in FIG. 2, and is provided with a connection portion for connection with the mouse 10 2. The back surface 1 42 b is a surface that is perpendicular to the Y axis shown in FIG. 3 and faces the front surface 1 42 a. The upper surface 1 42 c is a surface that is horizontal to the circuit board 140 shown in FIG. 3 and is perpendicular to the Z-axis. The pair of side surfaces 1 4 2 b are surfaces perpendicular to the front surface 1 42 a, the back surface 1 4 2 b, and the top surface 142 c.

Further, a cable 144 described later is also connected to the circuit board 140. In this embodiment, the cable 144 has two cables connected to the antenna for wireless LAN, one cable connected to the antenna for Bluetooth, and a connector for connecting a telephone line jack for the modem. A total of four cables connected to the cable are bundled in parallel.

The frame 150 is screwed to the lower force par of the casing 1 3 2 and is also screwed to the circuit board 140. As a result, the frame 150 is the circuit board 1 40 housing 1 3 Fix to 2 and protect from external force. The frame 150 is made of metal, and also acts as an electromagnetic shield, ground, and heat dissipation. As shown in FIG. 3, the frame 150 has a base portion 15 2, an upright portion 1 54, and a bent portion 1 5 6.

The base portion 152 is fixed to the circuit board 140 with screws (not shown) and is also fixed to the base 130 with screws (not shown).

The upright portion 1 54 is formed by bending the base portion 1 52 by 90 degrees, and has a circular through hole 1 54 a and a pair of protrusions 1 54 b in relation to the connector 1 42. The through hole 1 54 a exposes the connection portion of the front surface 1 42 a of the connector 1 42. The upright portion 1 54 can contact the front surface 1 42 a of the connector 1 4 2 that is not exposed through the through hole 1 54 a and restricts the movement of the connector 1 4 2 in the Y direction. Pair of protrusions 1 5

4 b extends from the standing part 1 54 to the inside of the frame 150 along the Y direction. The bent portion 156 is formed by bending the upright portion 1 54 along the inner side of the 90-degree frame 150, and includes a presser 1 56a and a pair of screwing portions 156b. The presser 1 5 6 a covers a part of the upper surface 142 c of the connector 1 42, but is separated from the upper surface 1 4 2 c. Each screwing part 1 5 6 b has a screw hole and presser 1

5 6 a are arranged on both sides.

The metal fitting 200 has a function as a reinforcing member that reinforces and fixes the connector 1 4 2 and is made of metal in this embodiment, but the present invention does not require that the reinforcing member be made of metal. For example, the reinforcing member may be integrally formed of plastic or the like. However, since the metal fitting 200 of the present embodiment is formed by bending a sheet metal, it is not necessary to use a plurality of members and the manufacture is easy. Furthermore, the metal fitting 200 can have a ground function. Hereinafter, the structure of the metal fitting 200 will be described with reference to FIGS. 4 (a) to (e). 4 (a) is a front perspective view of the metal fitting 200, and FIG. 4 (b) is a rear perspective view of the metal fitting 200. FIG. FIG. 4 (c) is a top view of the metal fitting 200, and FIG. 4 (d) is a rear view of the metal fitting 200. FIG. 4 (e) is a side view of the metal fitting 200. FIG. The metal fitting 200 includes a front surface portion 2 10, a pair of side surface portions 220, an upper surface portion 230, two pairs of projecting portions 240 and 25 0, and a holding portion 260. The front surface portion 2 10 has a substantially rectangular shape parallel to the rear surface 1 4 2 b of the connector 1 4 2 and has a pair of protrusions 2 1 2. The protrusion 2 1 2 protrudes in the Y-axis direction from the upper end of the front face 2 1 0 toward the back face 1 4 2 b of the connector 1 4 2. The protrusion 2 1 2 is formed by bending from the front surface portion 2 10. The protrusion 2 1 2 functions as a restricting portion that restricts the rotation of the connector 1 4 2 shown in FIG. 3 around the Z axis and restricts the movement of the connector 1 4 2 along the Y axis. The protrusion 44 of the conventional bracket 40 was placed in the center, so the rotation of the connector 14 around the Z axis could not be restricted, but the protrusion 2 1 2 was at both ends of the front 2 10 Since it is provided, the rotation of the connector 1 4 2 can be restricted. The position of the protrusion 2 1 2 is not limited to the top of the front surface 2 1 0, but the connector 1 4 2 is fixed at the bottom of the circuit board 1 4 0, so easily influenced. For this reason, it is preferable that the position of the protrusion 2 1 2 is at the upper part of the front surface portion 2 10. Further, the number and shape of the protrusions 2 1 2 are not limited to this embodiment. For example, another protrusion is provided at the center of the front face 2 10 and the back face 1 4 2 b of the connector 1 4 2 is supported at three points. Since the three points can define a surface, this enables to restrict the rotation of the connector 1 4 2 around the X axis in Fig. 3.

The pair of side surface portions 220 are rectangular thin plate portions parallel to the pair of side surface 14 2 d of the connector 14 2. The side surface portion 2 20 is formed by bending the front surface portion 2 1 0 90 degrees. The front surface portion 2 1 0 and the pair of side surface portions 2 2 0 have a U-shaped cross section that can accommodate the connector 1 4 2 therein. The pair of side surface portions 2 20 functions as a restricting portion that restricts movement of the connector 14 2 in FIG. 3 in the X direction. Note that the present invention does not require that the protrusion 2 1 2 that restricts the rotation of the connector 1 4 2 around the Z-axis is always provided on the front face 2 1 0. For example, a pair of protrusions are provided on the side surface portion 220 along the Y-axis direction.

The upper surface portion 2 3 0 is a rectangular thin plate portion parallel to the upper surface 1 4 2 c of the connector 1 4 2. The upper surface portion 2 30 is formed by bending the front surface portion 2 1 0 90 degrees. The upper surface portion 2 3 0 is inserted between the presser 1 5 6 a of the frame 1 5 0 and the upper surface 1 4 2 c of the connector 1 4 2. The top surface 2 3 0 is in surface contact with the top surface 1 4 2 c of the connector 1 4 2 to restrict the movement of the connector 1 4 2 along the Z axis and Also prevents the rotation of the nectar 1 4 2. Unlike the top plate retainer 24 in FIG. 8, the upper surface 2 30 is in contact with the connector 14 2, so that the connector 14 2 is less likely to move in the Z-axis direction than before. For this reason, the metal fitting 200 is reinforced and fixed in the Z-axis direction and around the X-axis, which has been insufficiently reinforced and fixed in the past. If it is difficult for the upper surface 2 3 0 to come into surface contact with the upper surface 1 4 2 c, a pair of protrusions are provided along the Y-axis direction on the upper surface 1 4 2 c side of the upper surface 2 3 0, and the X axis The connector 1 4 2 may be more reliably prevented from rotating. Alternatively, in order to restrict the rotation of the connector 14 2 around the X axis, the upper surface portion 2 30 is curved upward or convex when viewed from the Y direction, or a pair of extension portions 2 6 2 described later As such, it may be provided as a pair of extensions.

The overhanging portion 2 40 is a thin plate portion having a substantially rectangular shape extending from each of the pair of side surface portions 2 20 in parallel to the upper surface portion 2 30. The overhanging portion 2 4 0 is formed by bending the side surface portion 2 2 0 90 degrees. Each overhanging portion 2 4 0 has a (female) screw hole 2 4 2, and is fixed to the screw fixing portion 1 5 4 a of the frame 1 5 0 through the screw hole 2 4 2 through screws 1 6 0. Is done. Since the overhanging portion 2 40 is fixing the side surface portion 2 2 0, this restricts the connector 1 4 2 from moving in the X direction. The vertical relationship between the screwing portion 1 5 4 a and the overhanging portion 2 40 is opposite to that of the screw holes 2 2 a and 4 2 shown in FIG. That is, in FIG. 8, the screw hole 42 is disposed on the screw hole 22a, but in this embodiment, the screwing portion 1554a is disposed on the overhanging portion 240. As a result, even if the screw 1 60 is loosened, the reinforcing effect of the connector 1 4 2 is maintained because the screw fixing portion 1 5 4 a presses the metal fitting 2 0 0.

The overhanging portion 2 50 is a substantially rectangular thin plate portion extending in parallel with the front surface portion 2 10 from each of the pair of side surface portions 2 2 0. The overhang portion 2 5 0 is formed by bending the side surface portion 2 2 0 90 degrees. Each overhang 2 5 0 has a recess 2 5 2. Each recess 2 5 2 engages with the projection 1 5 4 b of the frame 1 5 0 and restricts the rotation of the connector 1 4 2 around the Y axis. Of course, a recess may be provided in the frame 150 and a protrusion may be provided in the overhanging portion 250. For this reason, the metal fitting 200 is reinforced and fixed to the connector 14 around the Y axis, which has been insufficiently fixed in the past.

The holding part 2 60 holds the conductive part 1 4 5 of the cable 1 4 4 connected to the circuit board 1 4 0, and electrically connects the cable 1 4 4 to the frame 1 5 0 to connect the cable 1 4 4 Has the function of grounding. In the metal fitting 20 0, the holding portion 2 60 has the function of the spacer 50 shown in FIG. 8 to reduce the number of parts. If the adhesive strength of the tape 52 is reduced, the space performance of the spacer 50 is lowered. In addition, the conductivity of the conductive coating 62 and the tape 52 and the conductivity of the tape 52 and the metal fitting 30 also affect the grounding performance. For this reason, the grounding performance of the cable 60 has been unstable in the past. On the other hand, unlike the spacer 50, the bracket 20 0 is not affected by the decrease in the adhesive strength of the tape 52, and the number of intervening conductive parts is small. This is better than via spacer 50. In addition, the holding unit 2600 has predetermined electrical characteristics or communication characteristics so that the cable 1 4 4 is separated from the circuit board 1 4 0 by a certain distance so as not to be affected by noise from the circuit board 1 4 0. Can be maintained.

The holding portion 2 60 has a height different from that of the pair of protruding portions 2 6 2 extending along the Y axis from both lower ends of the front portion 2 10, and the protruding portion 2 6 2 from the lower center of the front portion 2 1 0. And has a protruding portion 2 6 4 extending along the Y axis. In the present embodiment, the projecting portion 26 4 extends at a position lower than the projecting portion 26 2, but the projecting portion 2 62 2 may extend at a position lower than the projecting portion 2 64. The holding part 2 60 holds the cable 1 4 4 by sandwiching the conductive part 1 4 5 of the cable 1 4 4 between the protruding parts 2 6 2 and 2 6 4. The length of the protrusions 2 6 2 and 2 6 4 is set to a length that can accommodate a plurality of parallel cables (four in this embodiment) 1 4 4. As a result, electrostatic discharge (ESD), electromagnetic interference (E M I), and wireless communication characteristics of the cable 144 are improved.

Hereinafter, the mounting of the metal fitting 200 will be described with reference to FIGS. Here, FIG. 5 is a partially enlarged perspective view showing a state in which the metal fitting 20 0 is attached to the frame 1 5 0 to which the circuit board 1 4 40 is fixed. FIG. 6 is a partially enlarged perspective view showing a state where the metal fitting is attached in FIG. FIG. 7 is a partially enlarged perspective view showing a state in which the cable 14 4 is held by the holding part 2 60 in the state shown in FIG.

As shown in Fig. 5, the bracket 2 0 0 has the upper surface 2 3 0 positioned between the upper surface 1 4 2 c and the presser 1 5 6 a, and the overhang 2 4 0 is the screwing portion 1 5 6 b Is inserted in the direction of the two-dot chain line arrow so that the recess 2 5 2 fits into the projection 1 5 4 b. After the metal fitting 2 0 0 is mounted, the metal fitting 2 0 0 is fixed to the frame 1 5 0 with the screw 1 60. As a result, as shown in Fig. 6, the protrusion 2 1 2 receives the back surface 1 4 2 b, The upper surface portion 2 3 0 and the side surface portion 2 2 0 hold the outer shape of the connector 1 4 2. Thereafter, the conductive portion 1 4 5 of the cable 1 4 4 is held by the holding portion 2 60. As a result, as shown in FIG. 7, mounting of the metal fitting 200 is completed.

In operation, the user wears the mouse 10 2 in the office and separates it when carrying it. At that time, external force is applied to the connector 1 4 2, but the metal fitting 2 0 0 reinforces and fixes the connector 1 4 2 in various directions to prevent the damage. As a result, the connector 1 4 2 can maintain the expected life.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made. For example, in this embodiment, the bracket 20 0 is applied to the connector 14 2 for the mouse 10 2, but the present invention is a connector that is not highly stable in connection, such as a printer connector (for example, an AC adapter). It can be applied to connectors for video, video (S-OUT), and USB devices (especially when only one USB connector is provided). The connector such as S—O U T does not have to be an input / output connector. Further, it is as described above that the reinforcing member of the present invention does not need to be made of metal. The connector to be applied with force is not limited to a substantially rectangular parallelepiped shape. For example, if the back of the connector 1 4 2 is shaped like a combination of a semicircle in the upper half and a rectangle in the lower half, the shape of the front face 2 1 0 is also the corresponding shape. The position of the protrusion 2 1 2 may be changed and may be provided in the lower half of the front surface portion 2 1 0 so as to contact the rectangular portion of the lower half. Industrial applicability

The present invention can provide a reinforcing member that reinforces the fixing of the connector as compared with the prior art, and an electronic device having the same, preferably while realizing multi-functionality.
