Description

  The present invention relates to a technique for fixing an electronic device and a cable electrically connected thereto.

Conventionally, as a method of fixing a cable attached to an electronic device, the cable is sandwiched between cable clamps (clip-like fasteners) and provided in a through hole provided at one end of the clamp and an electronic device to be attached. A method of fixing the cable by fastening the attached mounting hole with a screw or the like is used. (For example, see Patent Document 1)

Alternatively, a plurality of protrusions are formed inside the panel constituting the electronic device, and the cable is entangled across the plurality of protrusions, so that the cable is fixed so as not to come off. (For example, see Reference 2)

Further, a method has been used in which an L-shaped fixing member provided with a cable locking portion at the tip is fastened with a screw or the like so as to be arranged on the bottom plate portion of the electronic device, and the cable is fixed. (For example, see Reference 3)

On the other hand, when connecting external devices to an electronic device such as a computer recently, the user has to manually set the connection software after unifying the standard of connection parts such as expansion cards that need to be added for each external device. A PnP (plug and play) method is widely used in which an OS automatically detects a card and performs optimum settings without performing work. As such PnP, a USB cable (Universal Serial Bus), which is one of the data transmission path standards that can easily connect / disconnect between an electronic device and a cable connected to the electronic device and switch between connected / unconnected states and has a high transmission speed. Cable) is often used.

By the way, the above-mentioned USB cable was intended for use in the field of facilitating connection / disconnection and switching between connected / unconnected states, but with the widespread use of the standard, it is easy to connect to various devices. In order to ensure connection compatibility, it will also be used in connections between devices that have not been required to be frequently disconnected in the past, so that the problem of easily disconnecting may occur. became.

For example, when a host device such as a computer system that needs to maintain a constant connection state and an electronic device corresponding to the lower device are connected by a USB cable to communicate information data, a cable connected to the outside of the device of the electronic device May suddenly come off due to some shock, the communication processing may be interrupted and the communication data may be lost in both the host device and the electronic device that is the lower device. In such a case, there is a problem that the work of restoring the communication connection is complicated and takes a lot of time and effort. Therefore, when a USB cable is used to connect an electronic device that does not need to be frequently connected and disconnected, it is necessary to fix the connection state, and as simple as possible to maintain this fixed state. There is a need for a method of preventing the disconnection of electronic devices and cables with a structure.

It is good to have established. With this configuration, the fixing member can be rotated with a small force at a position farthest from the rotation shaft, and the cable can be securely held in the vicinity of the knob. Therefore, it is possible to smoothly change the switching between the fixing position and the fixing release position of the fixing member.

In the cable fixing mechanism of the present invention, the fixing member is preferably formed of an elastic material. By comprising in this way, cable clamping and its cancellation | release can be easily performed by the elastic deformation of a fixing member. Further, when the fixing member is elastically deformed, it can be attached with one touch even when the fixing member is attached to and detached from the circuit board.

It is provided at the tip.

(Cable fixing procedure)
The cable fixing procedure by the cable fixing structure will be described below. FIG. 3 is a perspective view showing a state in which the fixing member is attached to the circuit board of the card reader. FIG. 4 is a perspective view showing a state in which the fixing member is in the fixing release position.

Since the fixing member 10 is formed of an elastic metal member, first, the arm portion 11 is elastically deformed with fingers or the like, and the protrusions 7 and 7 are fitted into the holes 11a and 11a, and then the fingers or the like are inserted. When the is released, the elasticity works and the fixing member 10 expands to return to its original shape and fits within the width of the cut opening 6a between the protrusions 7 and 7. In this manner, the fixing member 10 is mounted so as to be rotatable around the support shaft constituted by the protrusions 7 and 7 and can be attached to the circuit board 2.

Next, the plug 5 is connected to the socket 3 provided on the circuit board 2. As shown in FIG. 3, when the plug 5 is connected to the socket 3 that is directly attached to the circuit board 2 with almost no gap, the thickness of the covering portion of the plug 5 is fitted into the notch 6, and the plug 5 The thickness of the covering portion of the plug 5 sinks into the notch portion 6 without buffering the covering portion and the circuit board 2. The cable 4 and the plug 5 are detachable from the socket 3, and the fixing member 10 is in the fixing release position.

Next, as shown in FIG. 4, when the knob 15 is picked with fingers or the like and the fixing member 10 is rotated in the direction of arrow A, the fixing member 10 makes the socket 3 and the plug 5 undetachable. It becomes a fixed position. In this fixed position, the holding portions 13 and 13 hold the cable 4, and at the same time, the contact portions 14 and 14 come into contact with the shoulder portion 8 of the cable 4. Since the sandwiching portions 13 and 13 are elastically displaced, when they are pressed against the cable 4, the sandwiching portions 13 and 13 expand according to the thickness of the cable and the sandwiching width is widened. And when the cable 4 fits between the clamping parts 13 and 13, it will shrink | contract and will return to the original shape, and since the clamping parts 13 and 13 clamp the cable 4, the cable 4 and the fixing member 10 will be in an engagement state. The abutting portion 14 abuts on the shoulder portion 8 of the plug 5 to prevent the plug 5 from coming off from the socket 3 by sandwiching the plug 5 with the socket 3. In this way, a state in which the fixing member 10 is engaged with the cable 4 and the plug 5 and the socket 3 are prevented from being detached is defined as a fixing position.

(Effect of this embodiment)
As described above, in the cable fixing structure of this embodiment, since the fixing member 10 is attached to the circuit board 2, the cable 4 can be reliably fixed from the vicinity of the socket 3 that is an insertion port. Further, since the fixing member 10 is attached so as to be able to rotate the circuit board, the fixing member 10 can be changed to the fixing position and the fixing releasing position without removing the fixing member 10. Further, at the fixed position, the holding portions 13 and 13 hold the cable 4 and at the same time the abutment portion 14 abuts against the shoulder portion 8 of the cable 4 to hold the fixed position, thereby improving the reliability of preventing plug disconnection. It is done.

In this embodiment, the notch 6 is formed in the socket 3 toward the insertion port so that the circuit board 2 is not buffered when the socket 3 and the plug 5 are connected to the circuit board 2. Therefore, even when the socket 3 is provided on the circuit board 2, the covering portion of the plug 5 can be connected to the plug 5 and the socket 3 without buffering the circuit board 2. As a result, the plug 4 does not occupy extra space in the card reader 1.

In this embodiment, the fixing member 10 is formed of an elastic metal member. For this reason, by the biasing of the spring, the holding parts 13 and 13 are changed to the state in which the cable 4 is clamped and fixed and the state in which the fixed state is released by simple means of picking the knob 15 and rotating the fixing member 10. be able to. Further, since the knob 15 is located farthest from the support shaft of the fixing member 10 constituted by the protrusions 7 and 7, the knob 15 can be easily operated to rotate the fixing member 10 with a small force with fingers or the like. Fixing operability is good.

Further, the fixing member 10 can be easily detached from the circuit board 2 because the spring biasing works. As a result, the cable 4 can be removed with a single touch during the maintenance of the card reader 1, so that the work is not hindered, and the cable 4 can be smoothly replaced in the event of an abnormality such as the cable being disconnected. Can do.

[Embodiment 2]
FIG. 5 is a perspective view showing a rotation operation when a fixing member formed of a resin material according to the second embodiment of the present invention is attached to a circuit board. FIG. 6 is a perspective view showing a fixing member according to the second embodiment of the present invention. Embodiment 2 of the present invention will be described below. In addition, about the same component as 1st embodiment, the same code | symbol is used and illustration and description are abbreviate | omitted.

The difference between the first embodiment and the present embodiment is that the fixing member 20 is molded from an elastic resin material. Thereby, it becomes easier to elastically deform than the fixing member 10 of the first embodiment.

As shown in FIG. 5, the fixing member 20 is molded with an elastic resin material, and the arm portion 11 can be elastically deformed with fingers or the like, and is provided in a circular shape at one end of the arm portion 11. The protrusion 7 is fitted into the hole 11a and attached to the circuit board 2.

As shown in FIG. 6, the holding part 23 is provided so as to connect the pair of arm parts 11. The clamping part 23 clamps the cable 4 and prevents the cable 4 from being detached from the fixing member 20. The sandwiching portion 23 is formed in a substantially cylindrical shape, and a side wall thereof is partially opened so that the cable 4 can be received. The clamping part 23 is connected and held by arm parts 11 and 11 which are horizontal with respect to the support shaft of the fixing member 20 constituted by the projecting parts 7 and 7. Further, the contact portion 24 and the knob 15 are integrally connected and held to the arm portion 11.

The contact portion 24 contacts the shoulder portion 8 of the cable 4 to fix the cable 4. The contact portion 24 is provided on the side surface of the clamping portion 23 on the side close to the support shaft of the fixing member 20. The knob 15 is a knob that is picked with fingers or the like and receives a force for rotating the fixing member 20. The knob 15 is provided in a diagonally upward direction on the side surface of the clamping portion 23 that is far from the support shaft of the fixing member 20.

(Fixing procedure in this embodiment)
FIG. 5 is a perspective view showing a rotation operation when a fixing member formed of a resin material according to the second embodiment of the present invention is attached to a circuit board. As shown in FIG. 5, the fixing member 20 is attached to the circuit board 2 to fix the cable 4, and the fixing procedure is the same as in the first embodiment. Note that the arrow B indicates the rotating operation of the fixing member 20. When the fixing member 20 rotates in the direction of the arrow B, the fixing member 20 becomes a fixed position indicated by a dotted line fixing the cable 4, and is opposite to the arrow B direction. The fixing member 20 is a fixed release position indicated by a solid line in which the cable 4 is released.

(Effect in the present embodiment)
The cable fixing structure configured in this way can also obtain the same effects as the cable fixing structure of the first embodiment described above.

In the cable fixing structure according to this embodiment, the holding portion 23 and the contact portion 24 of the fixing member 20 are formed in a circular shape. As shown in FIG. 5, when the fixing member 20 is rotated in the direction of the arrow B to reach the cable fixing position, the holding portion 23 is made to adhere easily along the shape of the cable 4. For this reason, the strength of cable fixing increases, and a more reliable cable fixing structure can be obtained.

In the cable fixing structure in this embodiment, the elastic force is increased by molding the fixing member 20 with a resin material. The fixing member 20 is rotated to release the holding of the holding unit 23 and the contact of the contacting unit 24 from the fixed position where the cable 4 is fixed by the holding unit 23 and the contacting unit 24. Thus, the operation of changing the fixed release position can be easily performed with less force. The same effect can be expected when the fixing member 20 is attached to or detached from the circuit board 2.

Further, since the fixing member 20 is formed of an elastic resin material, if the burrs at the edge portion generated when the fixing member 20 is formed of a metal material rubs against the cable 4 or the plug 5 and wear increases, the cable 4 is disconnected. The reliability to the cable fixing structure is further increased. Furthermore, it can be expected that the production cost can be reduced as compared with the case where the fixing member is formed of a metal material.

[Embodiment 3]
Recently, in order to connect a large number of electronic devices, plugs having different sizes and shapes are used according to the connection state of each user's electronic device. The fixing member 10 of the present invention can also be provided with adjusters corresponding to different plug sizes. Next, an example will be described.

FIG. 7 is a perspective view showing a fixing member according to the third embodiment of the present invention. FIG. 7 shows a state where the adjustment width of the fixing member 30 is the longest. FIG. 8 shows a state where the adjustment width of the fixing member 30 is the shortest. In the present embodiment, 30 fixing members can be adjusted.

As shown in FIG. 7, the fixing member 30 has an arm body 301 having a connecting portion 37 for connecting the arm portions 11, 11, and an adjustment fixing having an insertion port 32, a holding portion 33, a contact portion 35, and a claw 36. Part 302.

The arm body 301 has an arm portion 11, a hole 11 a, a latch 31, and a locking groove 34, and is attached to the circuit board 2 so as to be rotatable. The latch 31 is a portion of the connecting portion 37 that is perpendicular to the rotation axis. When the latch 31 is inserted into the insertion slot 32, the jagged locking groove 34 of the latch 31 engages with the claw 36. In addition, the adjustment fixing portion 302 can be moved with respect to the arm body 301.

The adjustment fixing part 302 has an insertion port 32, a clamping part 33, a contact part 34, and a claw 36. The claw 36 is provided in the vicinity of the insertion port 32 and is formed so as to engage with any one of the locking grooves 34 of the latch 31 inserted from the insertion port 32. When the latch 31 is inserted into the insertion port 32, the adjustment fixing portion 302 can move with respect to the arm body 301 in the direction of arrow C shown in FIG.

The fixing member 30 configured as described above is formed of an elastic member such as a resin, and the protruding portion 7 is fitted into the hole 11a and rotated around the circuit board 2 in the same manner as in the first and second embodiments. It is designed to be freely movable.

(Procedure for length adjustment in this embodiment)
In the present embodiment, first, the latch 31 is inserted into the insertion slot 32 with fingers or the like from the state shown in FIG. Next, the adjustment fixing member 302 is moved in the arrow C direction with respect to the arm body 301. Then, the movement of the plug 5 is adjusted so as to match the length of the plug 5 during the movement to the state shown in FIG.

After determining the fixing position as described above, the fixing member 30 is adjusted to an arbitrary length by engaging the claw 36 with the locking groove 34 of the latch 31 and fixed.

The adjustment fixing member 302 is movable in the direction of arrow C. However, when the fixing position is determined by engaging with the locking groove 34, the claw 36 is caught in the locking groove, so that it is opposite to the direction of the arrow C. It cannot be moved in the direction.

After adjusting the length of the fixing member 30 as described above, the knob 15 is rotated with fingers or the like so that the holding portion 33 holds the cable 4, and the contact portion 35 contacts the shoulder portion 8 of the plug 5. The cable 4 is fixed by contact.

(Effect of this embodiment)
In the cable fixing structure described above, the fixing member 30 is configured by the two members of the arm 301 and the adjustment fixing member 302, so that the adjustment fixing portion 302 is variable with respect to the arm portion 301. Since the distance between the abutting portion 35 that abuts against the shoulder portion 8 and the hole 11a of the supporting shaft that enables the fixing member 30 to rotate can be adjusted, the plug can be changed even if the specification is changed by replacing the cable 4. Therefore, it is not necessary to replace with a fixing member according to the length form of the cable, and labor and cost in cable replacement can be saved.
