Description

[Technical field]

[0001] The present disclosure relates to a mounting structure for a connector. [Background technology]

[0002] Conventionally, terminal members have been proposed that suppress board cracking and solder peeling caused by inserting and removing a connection cord (for example, Patent Document 1). Patent Document 1 proposes that the terminal member be fixed directly to the upper case, so that the solder is not subjected to a large external force caused by inserting and removing the connection cord.

[0003] [Patent Document 1] JP 2013-65435 A Summary of the Invention [Problem to be solved by the invention]

[0004] When installing a connector on a circuit board, it is common to try to prevent damage to the mounting part, such as cracking of the board or peeling of the solder, when loads such as plugging and unplugging are applied to the mounting part of the connector by increasing the mounting rigidity of the connector to the electronic device. In this case, the load on the mounting part of the connector is difficult to release, and if the load is applied repeatedly or if the load exceeds the allowable range, the mounting part of the connector may be damaged. In addition, there is a limit to how much the rigidity of the mounting part can be increased, making it difficult to sufficiently prevent damage to the mounting part of the connector.

[0005] The technology disclosed herein has been made in consideration of the above-mentioned circumstances, and has an objective to suppress damage to the connector mounting portion when a load is applied to the connector. [Means for solving the problem]

[0006] In order to solve the above problems, the technology disclosed herein employs the following configuration. An attachment structure as one aspect of the technology disclosed herein is an attachment structure for a connector used in an electronic device (hereinafter also simply referred to as an attachment structure). The attachment structure includes an equipment-side connector, a substrate, and a holder. The equipment-side connector is disposed inside the electronic device, and an external connector is connected thereto so as to be freely insertable and removable. The substrate is formed with an electric circuit, and the equipment-side connector is attached so as to be electrically connected to the electric circuit. The holder includes a support portion, a first arm portion, and a second arm portion, and has a predetermined elasticity and supports the substrate. The support portion supports the substrate. The first arm portion extends in one direction, and one end is connected to the support portion. The second arm portion is connected to the other end of the first arm portion, and extends in a direction different from the extension direction of the first arm portion, and an end different from the end connected to the first arm portion is fixed to a structural member of the electronic device. Effect of the Invention

[0007] According to the present disclosure, in a mounting structure used in an electronic device, damage to a connector mounting portion when a load is applied to the connector can be suppressed. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. Note that each configuration and their combination in the present embodiment is an example, and addition, omission, substitution, and other modifications of the configuration are possible as appropriate within the scope of the gist of the present disclosure. In addition, the present disclosure is not limited by the embodiment, but is limited only by the claims.

[0010] [Overall structure] FIG. 1 is a cross-sectional view of an electronic device 10 having a mounting structure 1, viewed from the side. FIG. 2 is a front view of the electronic device 10 having the mounting structure 1, in which the front of the electronic device 10 is partially enlarged. FIG. 3 is a perspective view of the electronic device 10 having the mounting structure 1, viewed from the rear. In the following, the overall structure of the electronic device 10 according to this embodiment will be described with reference to FIGS. 1, 2, and 3. The electronic device 10 is used in the cabin of a vehicle, for example, an automobile. The electronic device 10 of this embodiment is used as an in-vehicle device such as an audio device, a head unit, or a car navigation system, or as a part of an entertainment system, which is provided on the dashboard of an automobile. For convenience, as shown in FIG. 1, the first housing panel 13 side of the electronic device 10 is the front side, and the second housing panel 14 side is the rear side, and the front-rear direction is the Y direction. In this embodiment, the Y direction coincides with the insertion and removal direction of the external connector 15. Furthermore, as shown in FIGS. 1 and 2, the longitudinal direction of the holder 11 is the X direction (left-right direction), and the direction perpendicular to both the Y direction and the X direction is the Z direction (up-down direction). It should be noted that the axial directions, and the front, rear, right side, left side, upper side, and lower side based on each direction merely indicate the relative positional relationship of each element in this embodiment.

[0011] The electronic device 10 includes a holder 11, a board 12, a first housing panel 13, and a second housing panel 14. As shown in FIG. 1, the electronic device 10 has a housing (an example of a "structural component" in the present disclosure) formed by the first housing panel 13 and the second housing panel 14. The holder 11 and the board 12 are provided in an internal space 10S (an example of an "inside of an electronic device" in the present disclosure) formed by the first housing panel 13 and the second housing panel 14. The holder 11 is connected to the first housing panel 13 by a screw V1, and holds the board 12 by a screw V3. The holder 11 has a roughly L-shape, and supports the board 12 so that the board 12 is disposed in a predetermined position relative to the first housing panel 13.

[0012] The substrate 12 is an electronic substrate on which an electric circuit is formed. The substrate 12 in this embodiment is formed of a material having a certain degree of elasticity, such as a general printed circuit board. A device-side connector 121 is provided on the lower side of the substrate 12 in the Z-axis direction. The device-side connector 121 is provided so as to be electrically connected to the electric circuit of the substrate 12. FIG. 1 also shows an external connector 15 for enabling transmission and reception of electric signals between the substrate 12 and the outside. The external connector 15 is paired with the device-side connector 121 and is connected to the device-side connector 121 so as to be freely inserted and removed. However, the internal space 10S may further include a substrate other than the substrate 12. In this embodiment, a substrate on which an electric circuit including a processor or the like is formed is provided in the internal space 10S, and the substrate and the substrate 12 are electrically connected via a flexible wiring cable.

[0013] The mounting structure 1 in this embodiment includes a holder 11, a board 12, and an equipment-side connector 121. The mounting structure 1 is a connector mounting structure that can reduce the load on the equipment-side connector 121 provided on the board 12. The load in this embodiment is, for example, , a force applied in a direction different from the insertion / removal direction when the external connector 15 is inserted into or inserted into the device-side connector 121. The load is generated by twisting, scooping, or shaking the external connector 15 when the external connector 15 and the device-side connector 121 are engaged with each other, or when the external connector 15 and the device-side connector 121 are engaged with each other. In FIG. 1, as an example of the load, a force applied in the Z direction to the external connector 16 is shown by an arrow A1. In addition, in this embodiment, the user connects the external connector 15 in an insertable / removable manner, but this embodiment is merely one embodiment, and the mounting structure 1 may be used in a location where the user does not frequently insert or remove connectors from each other. More specifically, the mounting structure 1 may be used on the side or rear of the electronic device 10, or inside the electronic device 10.

[0014] As shown in FIG. 2, the device side connector 121 has a device side connector socket 1211, a connector housing 1212, and contacts 1213. The connector housing 1212 has a right side wall 12121, a lower wall 12122, a left side wall 12123, an upper wall 12124, and legs 12125. In this embodiment, the external connector 15 and the device side connector 121 are formed according to a predetermined standard so that they can be connected. For example, the external connector 15 and the device side connector 121 are formed in the shape of a USB Type-C interface connector. In this embodiment, the device side connector 121 is formed as a receptacle (female side), and the external connector 15 is formed as a plug (male side). In this embodiment, the legs 12125 of the device side connector 121 are attached to the board 12 by soldering or the like, and the device side connector 121 is fixed in a state in which the upper wall 12124 is abutted against the lower side surface of the board 12. Furthermore, the contacts 1213 of the device-side connector 121 have a plurality of signal lines, which are electrically connected to the electric circuit of the board 12 by soldering or the like. This allows the electronic board such as the board 12 to transmit and receive information to and from the outside, and to supply power from the electronic device 10 to the external device, via the contacts 1213. However, the form of the connector shape with the external connector 15 is only an example, and for example, the receptacle (female side) and the plug (male side) may be reversed, or the external connector 15 and the device-side connector 121 may be changed to a pair of audiovisual connectors such as HDMI (registered trademark) or AUX, or a USB connector of another shape, or the like.

[0015] The first housing panel 13 is used as a front panel facing the user, and the second housing panel 14 is used as a back panel on the rear side of the housing. The first housing panel 13 in this embodiment is molded from a resin such as plastic. However, the form of the first housing panel 13 is only an example, and for example, the material may be replaced with a metal or the like, or the shape may be appropriately changed. Similarly, the second housing panel 14 may be formed from a metal or a resin.

[0016] As shown in FIG. 1 and FIG. 2, the front side of the first housing panel 13 is formed in a flat shape, and a socket 131 (an example of an "external connector socket" in the present disclosure) that is an opening for inserting and removing the external connector 15 is formed on the front side. The socket 131 and the device side connector socket 1211 are arranged opposite to each other so that the external connector 15 can be connected to the device side connector 121 by inserting the external connector 15 into the socket 131. Also, as shown in FIG. 1, a gap of a distance d1 (an example of a "predetermined gap" in the present disclosure) is formed between the socket 131 and the device side connector socket 1211 in the insertion and removal direction of the external connector 15. As a result, when the external connector 15 is inserted into the device side connector 121, the external connector 15 is formed to be able to swing by the amount of the gap. As a result, for example, even if a load is generated in the direction of the arrow A1, the movement of the external connector 15 is limited to the size of the socket 131, and the load on the device side connector 121 can be distributed to the first housing panel 13. Furthermore, the first housing panel 13 may have an output device such as a display and an input device such as a touch panel. For example, an input device such as a touch panel installed on the first housing panel 13 may receive an operation by a user and send a signal corresponding to the operation to a board such as the board 12. The embodiment of the first housing panel 13 is merely an example, and the first housing panel 13 can be appropriately set depending on, for example, the intended use.

[0017] As shown in FIG. 1 and FIG. 3, a first screw receiving portion 132 is provided on the rear side of the first housing panel 13 in the Y-axis direction. Furthermore, as shown in FIG. 3, a second screw receiving portion 133 is provided on the rear side of the first housing panel 13 in a protruding manner substantially parallel to the first screw receiving portion 132. In this embodiment, the first screw receiving portion 132 and the second screw receiving portion 133 have internal threads. As shown in FIG. 1 and FIG. 3, when the screw V1 and the first screw receiving portion 132 are fastened, the holder 11 and the second housing panel 14 are fastened together. Note that the second housing panel 14 is omitted in FIG. 3. Also, as shown in FIG. 3, when the screw V2 and the second screw receiving portion 133 are fastened, the holder 11 is fastened together. However, the embodiment of the first housing panel 13 is an example, and for example, modifications such as increasing or decreasing the number of screw receiving portions protruding from the rear side of the first housing panel 13 or increasing or decreasing the number of parts to be fastened together can be appropriately made according to the application or situation.

[0018] 1 and 3, the rear side of the second housing panel 14 is formed in a flat shape, and a through hole 141 through which the screw V1 can be inserted is formed. In this embodiment, when the screw V1 and the first screw receiving portion 132 are fastened, the screw V1 is inserted into the through hole 141 to fix the second housing panel 14. Note that when the electronic device 10 is used by being attached to the dashboard of a vehicle, the second housing panel 14 is not essential, but the rear surface of the housing of the electronic device 10 of this embodiment is covered by the second housing panel 14, which improves convenience when carrying or removing the electronic device, and protects the board 12, etc.

[0019] FIG. 4 is a perspective view of the holder 11 used in the mounting structure 1. The holder 11 is a member for supporting the substrate 12 on the first housing panel 13. The holder 11 has a first arm portion 111, a second arm portion 112, a fastening portion 113, and a claw portion 114. The holder 11 is fixed to the first housing panel 13 via a part of the second arm portion 112 and a part of the fastening portion 113. The substrate 12 is engaged with the holder 11 by a part of the fastening portion 113 and a part of the claw portion 114. By fixing the holder 11 to each member at two points in this manner, the holder 11 is restricted from rotating relative to the first housing panel 13 in the XZ plane, and the substrate 12 is restricted from rotating relative to the holder 11 in the XY plane. The holder 11 is formed of a material capable of elastic deformation. The material of the holder 11 is not particularly limited, but may be formed by sheet metal molding using a metal such as carbon steel, stainless steel, or aluminum. This makes it possible to prevent breakage or plastic deformation of holder 11 even when holder 11 absorbs a load from external connector 15. Holder 11 may also function as a heat sink by efficiently conducting heat generated in substrate 12 to first housing panel 13 and second housing panel 14.

[0020] The first arm portion 111 extends in a plane in the Y-axis direction (the insertion / removal direction of the external connector 15). In the Y-axis direction, one end of the first arm portion 111 is connected to the fastening portion 113, and the other end is connected to the second arm portion 112. In this embodiment, a side portion of the first arm portion 111 including a front end portion of the first arm portion 111 is connected to the fastening portion 113. In the X-axis direction, the right side portion of the front portion of the first arm portion 111 is connected to the fastening portion 113, and the left side portion is connected to the claw portion 114. In this embodiment, the first arm portion 111 is formed in a plane, but it may be configured such that the first arm portion 111 supports the substrate 12 and also serves as a support portion by providing, for example, a welded nut or a projection for alignment.

[0021] The second arm portion 112 extends in a direction different from that of the first arm portion 111. In this embodiment, the second arm portion 112 extends approximately in the Z-axis direction. The second arm portion 112 has a connection portion 1121 and a fixing portion 1122. In this embodiment, the fixing portion 1122 extends flatly in the Z-axis direction and has a through hole 11221 through which the screw V1 can be inserted. One end of the connection portion 1121 is connected to the first arm portion 111, and the other end is connected to the fixing portion 1122. The connecting portion 1121 is formed so as to chamfer the corner that is assumed when the first arm portion 111 and the fixed portion 1122 are butted together, and connects the first arm portion 111 and the fixed portion 1122 such that the angle of the connecting portion with the first arm portion 111 and the angle of the connecting portion with the fixed portion 1122 are obtuse angles. In other words, the second arm portion 112 has one end (connecting portion 1121) connected to the other end of the first arm portion 111 and extends in a direction different from the extending direction of the first arm portion 111, and an end different from the end connected to the first arm portion 111 is fixed to the first housing panel 13 (a structural member of the electronic device). In this way, the first arm portion 111 and the second arm portion 112 of this embodiment are formed in a substantially L-shape.

[0022] The fastening portion 113 extends from one end of the first arm portion 111 in the X-axis direction. The fastening portion 113 includes a support column 1131, a support plate 1132, and a fixing portion 1133. The support column 1131 is erected on one end of the first arm portion 111 facing upward in the Z-axis direction, and an upper end surface of the support column 1131 is connected to a lower surface of the support plate 1132. The support plate 1132 is formed in a roughly rectangular flat shape. The support plate 1132 supports the substrate 12 on its upper surface, and further, one end in the Y-axis direction faces the first housing panel 13, and a fixing portion 1133 is disposed on the other end. The support plate 1132 is provided with a female screw 11321 that can fasten the screw V3 toward the Z-axis direction, and a protrusion 11322 for aligning the substrate 12 protrudes upward in the Z-axis direction. The fixing portion 1133 stands upward in the Z-axis direction from the rear end portion of the support plate 1132 in the Y-axis direction. The fixing portion 1133 has a through hole 11331 through which the screw V2 can be inserted, and a reinforcing rib 11332. The reinforcing rib 11332 prevents the fixing portion 1133 from bending in the Y-axis direction, and increases the rigidity of the fixing portion 1133.

[0023] Further, the height in the Z-axis direction of the support pillar 1131 is set so that a gap large enough to accommodate the device-side connector 121 can be formed between the first arm portion 111 and the substrate 12. Further, in this embodiment, the height in the Z-axis direction of the support pillar 1131 is set so that the device-side connector 121 does not come into contact with the first arm portion 111. However, the above-described aspect of the fastening portion 113 is merely an example, and for example, the fixing portion 1133 may be connected to the first housing panel 13 in another shape.

[0024] The claw portion 114 extends to the other end of the first arm portion 111 in the X-axis direction. The claw portion 114 has a claw portion support 1141 and a claw tip 1142. The claw portion support 1141 is erected upward in the Z-axis direction at the other end of the first arm portion 111, and a mounting portion 11411 is provided on which the board 12 can be mounted. The mounting portion 11411 cooperates with the support portion support 1131 and the support plate 1132 described above to form a gap between the first arm portion 111 and the board 12 to an extent that the device side connector 121 can be installed. The claw tip 1142 is inserted into a locking hole 122 of the board 12 described later, and clamps the board 12 between the mounting portion 11411 and the mounting portion 11411.

[0025] The configuration of the fastening portion 113 and the claw portion 114 is merely an example, and it is sufficient if the substrate 12 and the first arm portion 111 can be locked on the holder 11. More specifically, for example, the fastening portion 113 may be changed to a configuration such as the claw portion 114, or the fastening portion 113 may not be provided and only the claw portion 114 may be used for locking. In this embodiment, the front portion of the first arm portion 111 connecting the fastening portion 113 and the claw portion 114, the fastening portion 113, and the claw portion 114 constitute one form of a support portion. In other words, the front portion of the first arm portion 111 also serves as a support portion (bridge portion 115 described below).

[0026] [Assembled state] 5 is a perspective view illustrating a locked state between the holder 11 and the substrate 12 according to the embodiment. In this embodiment, the substrate 12 is placed on the upper surface of the support plate 1132 in the fastening portion 113 of the holder 11 and on the upper side of the placement portion 11411 provided on the substrate support 1141 of the substrate 114 with the claw tip 1142 of the substrate 114 inserted into the locking hole 122. The plate 12 and the first arm portion 111 are disposed so as to face each other in the Z-axis direction.

[0027] At this time, a protrusion 11322 protruding from the upper surface of the support plate 1132 of the fastening portion 113 engages with a positioning hole 124 provided in the substrate 12, whereby the substrate 12 and the fastening portion 113 are positioned.

[0028] The first arm portion 111 is disposed so as to face the board 12 in the Z-axis direction. At this time, the support portion pillar 1131 of the fastening portion 113, the claw portion pillar 1141 of the claw portion 114, and the front portion of the first arm portion 111 form a shape that covers the device side connector 121 installed on the board 12 on the lower side in the Z-axis direction. In this embodiment, the portion formed by the first arm portion 111, the support portion pillar 1131, and the claw portion pillar 1141 is defined as a bridging portion 115. In this embodiment, as shown in FIG. 5, the bridging portion 115 is disposed at a position separated by distances d2 to d4 from the device side connector 121, and is connected to the board 12 so as to straddle the device side connector 121 downward in the Z-axis direction.

[0029] Distances d2 and d3 indicate the distance between the device-side connector 121 and the bridge portion 115 in the X-axis direction (the direction perpendicular to the insertion / removal direction of the external connector 15) when the device-side connector 121 is viewed from the front of the connector's socket. Distance d2 indicates the distance between the support portion pillar 1131 and the right side wall 12121 of the connector housing 1212. Distance d3 indicates the distance between the claw portion pillar 1141 and the left side wall 12123 of the connector housing 1212. As a result, the holder 11 supports the board 12 at a position spaced apart by distances d2 and d3 from the device-side connector 121. In other words, since the holder 11 supports the board 12 at a position spaced apart from the soldered portion of the contact 1213, stress concentration on the soldered portion of the contact 1213 can be reduced by utilizing the elasticity of the board 12 itself when a load is applied.

[0030] Distance d4 (an example of a "predetermined gap" in the present disclosure) indicates the gap between the device-side connector 121 and the bridging portion 115 in the Z-axis direction (a direction perpendicular to the insertion / removal direction of the external connector 15) when the device-side connector 121 is viewed from the front of the connector socket. As a result, the holder 11 and the connector housing 1212 do not come into direct contact with each other, and therefore, when a load is applied, the connector housing 1212 and the contacts 1213 can swing together by utilizing the elasticity of the board 12. In other words, the stress that may be generated between the contacts 1213 and the connector housing 1212 when a load is applied can be absorbed by the elasticity of the board 12.

[0031] FIG. 6 is an exploded perspective view of an electronic device 10 including a mounting structure 1 according to this embodiment. As shown in FIG. 6, the holder 11 is connected to the first housing panel 13 by a screw V1 and a screw V2. The screw V1 has a head V11 and a shaft V12, and the screw V2 has a head V21 and a shaft V22. The first housing panel 13 is provided with a first screw receiving portion 132 and a second screw receiving portion 133. The first screw receiving portion 132 has a female screw 1322 formed inside an outer wall portion 1321. The second screw receiving portion 133 has a female screw 1332 formed inside an outer wall portion 1331. The board 12 is engaged with the holder 11 by a screw V3 and a claw portion 114. The screw V3 has a head V31 and a shaft V32. The holder 11 is provided with a female screw 11321.

[0032] The shaft portion V12 of the screw V1 is fastened to the female thread 1322 of the first screw receiving portion 132. At this time, the shaft portion V12 of the screw V1 is inserted into the through hole 11221 formed in the holder 11 and the through hole 141 formed in the second housing panel 14, and the screw V1 is fastened with the holder 11 and the second housing panel 14 sandwiched between the head portion V11 and the outer wall portion 1321.

[0033] The shaft portion V22 of the screw V2 is fastened to the female thread 1332 of the second screw receiving portion 133. At this time, the shaft portion V22 of the screw V2 is inserted into a through hole 11331 formed in the holder 11, and the screw V2 is fastened with the holder 11 sandwiched between the head V21 and the outer wall portion 1331.

[0034] The shaft portion V32 of the screw V3 is fastened to the female thread 11321 of the holder 11. At this time, the shaft portion V32 of the screw V3 is inserted into a through hole 123 formed in the substrate 12, and the screw V3 is fastened with the substrate 12 sandwiched between the head portion V31 and the support plate 1132. The female thread 11321 may be, for example, a welded nut welded to the holder 11.

[0035] The substrate 12 is formed with a locking hole 122 into which the claw tip 1142 of the claw portion 114 can be inserted. The substrate 12 is also formed with a positioning hole 124. The locking hole 122 and the positioning hole 124 engage with the claw tip 1142 and the protrusion 11322 of the holder 11, thereby determining the position of the substrate 12 on the holder 11. Furthermore, the shaft portion V32 of the screw V3 is inserted into the through hole 123 and screwed into the female thread 11321, thereby fastening the substrate 12 to the holder 11. That is, the holder 11 and the substrate 12 are locked at two points. As a result, the holder 11 restricts the substrate 12 from rotating relative to the holder 11, for example, in the XY plane.

[0036] [Effects] For example, the load applied to the external connector 15 is transmitted to the board 12 via the device-side connector 121. At this time, the board 12 fixed to the fastening portion 113 by the screw V3 moves together with the first arm portion 111 of the holder 11, and the load is reduced by the holder 11 being bent, and damage to the connector attachment portion is suppressed. In this embodiment, a gap of distances d2 to d4 is formed between the holder 11 and the device-side connector 121, so that the elasticity of the board 12 also relieves stress concentration, and damage to the soldered portion of the signal line included in the contact 1213, etc., can be suppressed.

[0037] The second arm portion 112 of the holder 11 is fixed to the first housing panel 13 with a screw V1. As a result, when a load is applied, stress is preferentially concentrated on the connection portion 1121 provided between the second arm portion 112 serving as the fulcrum and the first arm portion 111 serving as the force point in the holder 11. As a result, the holder 11 itself swings, and the load on the portion where the device side connector 121 and the board 12 are soldered can be reduced. Note that, in this embodiment, the second arm portion 112 of the holder 11 is fixed to the first housing panel 13, but this is not limiting, and the second arm portion 112 may be fixed to a structural member other than the first housing panel 13 as long as it is configured to be fixed in the electronic device 10.

[0038] In this way, by using the L-shaped holder 11 and providing a distance between the fulcrum (the point fixed by the screw V1) and the force point (the position where the load is applied, the external connector 15, etc.), the holder 11 can be swung and at the same time the board 12 can be swung as well. This suppresses damage to the connector attachment portion, such as cracking or peeling of the solder at the portion where the board 12 and the device-side connector 121 are connected, falling off of the device-side connector 121, and cracking of the board 12.

[0039] Furthermore, since the socket 131 provided on the first housing panel 13 is positioned opposite the device side connector socket 1211, even if an excessive load occurs, the external connector 15 will hit the wall surface of the socket 131, and the excessive load will be distributed to the first housing panel 13, thereby suppressing damage to the connector mounting portion.

[0040] According to the mounting structure 1 of this embodiment, in the electronic device 10 of the present disclosure, when a load is applied to the device-side connector 121, the board 12 and the first housing panel 13 can be fixed to the first housing panel 13 so that the board 12 can be oscillated. When external connector 15 comes into contact with socket 131 of panel 13, the load can be distributed to first housing panel 13. This makes it possible to prevent the load from concentrating on a firmly fixed point, and allows the load to be released to holder 11 and first housing panel 13. In other words, this prevents cracking of board 12, falling off of device-side connector 121, and cracking and peeling of the solder at the connection between board 12 and device-side connector 121.

[0041] Although the embodiments according to the present disclosure have been described above, each aspect disclosed in this specification can be combined with any other feature disclosed in this specification. [Explanation of symbols]
