Description

The present invention relates to connector port caps and the like.

Connectors based on standards such as USB (registered trademark) and HDMI (registered trademark) are known as connectors used for connecting electronic devices to other electronic devices. Here, USB (registered trademark) is an abbreviation for Universal Serial Bus. HDMI is an abbreviation for High Definition Multimedia Interface (registered trademark). A housing of an electronic device is generally provided with a port (female terminal) in which a terminal is arranged in an opening. By connecting the plug (male terminal) of a device or cable to this port, it becomes possible to access the board (body of the electronic device) inside the housing. On the other hand, in environments such as outdoors where there is a lot of dust and dirt, if the port is open, there is a problem that dust and dirt will enter through the opening. In addition, when the user is absent, if the port is open, there is a possibility that the electronic device may be accessed by connecting the device illegally.

Therefore, in order to protect the connector port and prevent unauthorized access, a method of attaching a cap that cannot be easily removed has been proposed.

For example, Japanese Laid-Open Patent Publication No. 2004-100003 discloses a technique of a closing cover having a front side portion (lid portion) that fits into an opening of a port and a locking arm that engages an upper ledge in the port. there is The closure cover has an access window in the center of the front side for insertion of a removal tool. When the fork of the removal tool is inserted through the access window, a ramp-shaped cam at the tip of the fork deflects the locking arm. This disengages the locking arm from the upper shelf. At this time, since the hook portion of the removal tool engages with the connection member provided on the front side portion, the closing cover can be removed by pulling out the removal tool. In this manner, the closing cover of Patent Document 1 can protect the connector port by forming the closing cover with a structure that cannot be removed without a special tool.

Further, Patent Literature 2 discloses a technique of a USB lock mechanism having an end portion (cover portion) without an opening that fits into a USB port. The USB locking mechanism has two guides extending to the far side of the USB port, and the tips of the guides are provided with claws that engage with cuts in the USB port. In addition, the USB lock mechanism includes an unlocking receiving portion arranged in front of the claw portion and connecting the guide portion, a cavity arranged between the end portion and the unlocking receiving portion, and a portion corresponding to the cavity at the end portion. and a thin film provided on the When removing the USB lock mechanism, the lock release member of the lock release mechanism (removal jig) having a rod-shaped or plate-shaped lock release member is inserted by breaking the thin film at the end. Then, the tip of the unlocking member pushes down the unlocking receiving portion of the USB lock mechanism, pushes down the guide portion connected thereto, pushes down the claw portion connected to the guide portion, and engages the claw portion with the notch. comes off. On the other hand, the unlocking concave portion of the unlocking mechanism is caught by the unlocking receiving portion of the USB locking mechanism. Therefore, the USB locking mechanism can be removed from the USB port by pulling out the unlocking mechanism. As described above, in the USB lock mechanism of Patent Document 2, the connector port can be protected by the USB lock mechanism by forming the USB lock mechanism with a structure that cannot be removed without a special tool.

(Second embodiment)
In the second embodiment, a method for removing the connector port cap 20 in the connector port protection structure 100 of the first embodiment will be described. The connector port cap 20 can be removed by inserting a connector port cap removing jig through the notch 23 .

FIG. 7 is a perspective view showing a state before the connector port cap removing jig 30 of the second embodiment is inserted into the connector port protection structure 100. FIG. The connector port protection structure 100 has the same configuration as that of the first embodiment shown in FIG.

The connector port cap removing jig 30 has a U-shaped bent plate material, and a pair of second arms 31 are arranged on the straight part of the U-shaped plate material. Inside the tip of the second arm 31, a second locking portion 32 is provided using a U-shaped inward convex step. It is desirable that the step of the second locking portion 32 is, for example, a right angle or an overhang shape. This is to increase the locking force when locking the connector port cap 20, which will be described later.

The connector port cap removing jig 30 including the second arm 31 can be formed, for example, by bending an elastic metal plate. In this case, the second locking portion 32 may be formed by folding a plate-like member inward and creating a step at the tip of the member. The pair of second arms 31 including the second locking portion 32 can pass through the notch portion 23 of the connector port cap 20 and enter the inside of the housing 200 (the back side of the lid portion 21). It has a shape. Therefore, the thickness of the second locking portion 32 and the second arm 31 must be smaller than the cutout width of the cutout portion 23 . For example, if the notch width is 0.1 to 1.0 mm, the plate material can be selected accordingly. The reason why the notch width is set in the above range is to expect the effect that a third party will give up removing the connector port cap 20, as described above.

FIG. 8 is a cross-sectional view showing a state before the connector port cap removing jig 30 of the second embodiment is inserted into the connector port protection structure 100. FIG. A connector port cap 20 is attached to the connector port 10, and a first locking portion 24 at the tip of the first arm 22 is fitted into a recess 13 on the side surface of the substrate 12 and fixed. The interval between the two second locking portions 32 of the connector port cap removing jig 30 is slightly narrower than the interval between the two cutout portions 23 of the connector port cap 20 . Specifically, for example, the stepped portion of the second locking portion 32 can be narrowed.

FIG. 9 is a cross-sectional view showing a state in the middle of inserting the connector port cap removing jig 30 of the second embodiment into the connector port protection structure 100. As shown in FIG. The tips of the two second arms 31 enter the corresponding cutouts 23 . At this time, since the interval between the two second locking portions 32 is slightly narrower than the interval between the two cutout portions 23, the interval between the tips of the two second arms 31 is slightly widened.

FIG. 10 is a cross-sectional view showing a state in which the connector port cap removing jig 30 of the second embodiment is engaged with the connector port cap. When the connector port cap removing jig 30 is further pushed toward the connector port 10 from the state shown in FIG. 21 is locked to the main surface of the first arm 22 side. At this time, the elasticity of the second arm 31 causes the gap between the two second locking portions 32 to return to its original position, so that the locking can be performed more reliably.

FIG. 11 is a sectional view showing a state in which the connector port cap is removed with the connector port cap removing jig 30 of the second embodiment. By pulling the connector port cap removing jig 30 away from the connector port 10 from the state shown in FIG. 10, the state shown in FIG. 11 with the connector port cap 20 removed can be obtained. Here, as described above, the step portion of the concave portion of the substrate 12 is an inclined surface with a smaller angle than a right angle. Further, the step of the second locking portion 32 of the connector port cap removing jig 30 has a right angle or an overhang shape. Therefore, the second locking portion 32 of the connector port cap removal jig 30 is locked to the lid portion 21 by the force of the first locking portion 24 of the connector port cap 20 fitting into the concave portion 13 of the substrate 12 . The power to do is getting stronger. Therefore, the connector port cap 20 can be removed against the force of the first locking portion 24 fitting into the recess 13 .

The connector port cap removing jig 30 and the method for removing the connector port cap 20 according to the second embodiment of the present invention have been described above.

A connector port cap removal jig 30 according to the second embodiment of the present invention is used when removing the connector port cap 20 from the connector port 10 . The connector port cap removing jig 30 has a pair of second arms 31 and a second locking portion 32 . The pair of second arms 31 can be inserted into the housing 200 through the pair of notches 23 when the connector port cap 20 is removed from the connector port 10 . The second locking portion 32 is formed at the tip of each of the pair of second arms 31 . When the connector port cap 20 is removed from the connector port 10 and inserted into the housing 200 through the pair of cutouts 23 , the second locking portion 32 locks into the cutouts 23 .

Thus, the pair of second arms 31 can be inserted into the housing 200 through the pair of notches 23 when removing the connector port cap 20 from the connector port 10 . Therefore, the distal end of the connector port cap removal jig 30 can be arranged inside the pair of notches 23 inside the pair of second arms 31 inside the housing 200 . Also, the second locking portion 32 is formed at the tip of each of the pair of second arms 31 . When the connector port cap 20 is removed from the connector port 10 and inserted into the housing 200 through the pair of cutouts 23 , the second locking portion 32 locks into the cutouts 23 . That is, the second locking portions 32 formed at the distal end portions of the pair of second arms 31 are engaged with the housing 200 through the pair of cutout portions 23 when the connector port cap 20 is removed from the connector port 10 . When it is inserted into the inside, it is locked in the notch portion 23 . Therefore, when the second arm 31 is inserted into the housing 200 , the pair of second locking portions 32 are locked to the pair of notch portions 23 . With the pair of second locking portions 32 locked to the pair of notches 23, the connector port cap removing jig 30 is moved away from the housing 200, thereby removing the pair of first locking portions. The locking portion 24 can be removed from the recess 13 . At this time, the connector port cap 20 moves in conjunction with the connector port cap removing jig 30 by engaging the pair of second locking portions 32 with the pair of notch portions 23 . Therefore, by pulling out the connector port cap removing jig 30, the connector port cap 20 can be removed from the connector port 10 (connector port protection structure 100). Since the connector port cap 20 can be removed using the connector port cap removing jig 30 in this way, the connector port cap 20 can be used repeatedly.
