Further, the outer cylinder 10 of the key cylinder 1 and the screw member insertion portion 2 are integrally formed as a lock body B by plastic. This point will be described later.
As shown in fig. 3, the screw member insertion portion 2 is formed in a substantially cylindrical shape with both ends open along the outer peripheral surface of the outer cylinder 10 of the key cylinder 1. In the present embodiment, the screw member insertion portion 2 is formed as a part of the lock body B in a substantially cylindrical shape having a diameter larger than the outer diameter of the screw portion S of the equipment-side connector and a length equal to the length of the outer cylinder 10, integrally with the outer circumferential surface of the outer cylinder 10. The rear end of the inner peripheral surface of the screw member insertion portion 2 is formed into a substantially cylindrical covering portion 20 of a medium diameter that can communicate with and be externally fitted to the screw portion S of the equipment-side connector, the front end of the inner peripheral surface of the screw member insertion portion 2 is formed into a substantially cylindrical shape of a large diameter that can be fitted to a head portion 30 of a screw member 3 to be described later, the length of which is substantially equal to the length of the head portion 30 and the diameter of which is slightly larger than the diameter of the head portion 30, the front end is provided with a circular opening 210, and a predetermined range of the front end side is a head holding portion 21. An intermediate portion between the covering portion 20 on the rear end side and the head holding portion 21 on the front end side is formed into a substantially cylindrical shape having a small diameter and including a screw hole 22 and a screw insertion hole 23, the screw hole 22 being a part of the rear end side through which the screw shaft 31 of the screw member 3 can be inserted, and the screw insertion hole 23 being the remaining part of the front end side.
As shown in fig. 4, the screw member 3 is composed of a head 30 and a threaded shaft 31, and the screw member 3 is integrally insertable into the screw member insertion portion 2 and the threaded shaft 31 is threadably engaged with the threaded portion S of the equipment-side connector. In this case, the screw member 3 is constituted by a cylindrical head portion 30 and a threaded shaft 31, the head portion 30 is fittable to the head holding portion 21 on the front end side of the inner peripheral surface of the screw member insertion portion 2, and the threaded shaft 31 is projected from the center of the front end surface of the head portion 30 and has a threaded portion on the outer peripheral surface within a predetermined length range from the front end. The entire screw member 3 is inserted into the screw member insertion portion 2, the head 30 is held by the head holding portion 21, the screw shaft 31 is inserted through the screw insertion hole 23 and the screw hole 22 in the middle portion, and the front end side of the screw shaft 31 is disposed in the covering portion 20 in a protruding manner.
As shown in fig. 5, the lock cover 4 is composed of a cover rotating portion 41 and a cover portion 42, the cover rotating portion 41 is formed in a ring shape by dividing the front end side of the outer cylinder 10 of the key cylinder 1, and the cover portion 42 is formed in a convex shape in a part of the outer peripheral surface of the cover rotating portion 41 and has substantially the same shape as the shape of the front end surface of the screw member insertion portion 2 having the opening 210. The cap rotating portion 41 and the inner cylinder 11 can be integrally rotated on the front end side of the outer cylinder 10 by engaging the engaging concave portion 40 formed on the annular inner peripheral surface of the cap rotating portion 41 with the engaging convex portion 112 (see fig. 2 (b)) formed on the front end side of the outer peripheral surface of the inner cylinder 11 of the key cylinder 1. The engagement between the engaging recess 40 and the locking projection 112 operatively connects the lock cover 4 to the inner cylinder 11 on the front end side of the key cylinder 1. The cover rotating portion 41 and the inner cylinder 11 are rotated together about the axis of the key cylinder 1 by rotating the key 12 inserted into the key hole 110 of the key cylinder 1, and the cover 42 is rotated between a lock position at the distal end opening 210 of the screw member insertion portion 2 and an unlock position away from the opening 210, so that the cover 42 can open and close the opening 210 of the screw member insertion portion 2.
In this way, in the connector locking device L, when the equipment-side connector is prevented from being used illegally, the connecting surface of the equipment-side connector is covered and closed by the covering portion 101 of the key cylinder 1, and the covering portion 101 and the connecting surface of the equipment-side connector are fixed by fastening the screw member 3 in the screw member insertion portion 2 to the screw portion S on one side of the equipment-side connector. Next, the key 12 is inserted into the key hole 110 of the key cylinder 1 and rotated to close the opening 210 of the screw member insertion portion 2 by the lock cover 4, the key 12 is pulled out from the key hole 110 to lock the key cylinder 1 to lock the lock cover 4, and the cover portion 101 of the key cylinder 1 is locked to the connection surface of the device-side connector.
When the device-side connector is used, the key cylinder 1 is unlocked by inserting the key 12 into the key hole 110, thereby unlocking the lock cover 4 and the cover portion 101 of the key cylinder 1 with respect to the connection surface of the device-side connector, and the lock cover 4 is moved away from the opening 210 of the screw member insertion portion 2 by the rotational operation of the key 12, thereby opening the opening 210. Next, the screw members 3 in the screw member insertion portions 2 are removed from the screw portions S, whereby the cover portion 101 of the key cylinder 1 and the connection surface of the device-side connector are released from being fixed.
Fig. 6 illustrates a use example of the case where the connector locking device L is used for the DVI. In the connector locking device L of the present embodiment, the outer cylinder 10 of the locking body B is formed in a substantially cylindrical shape having an inner diameter slightly smaller than the long-side dimension of the DVI and slightly larger than the short-side dimension of the DVI, and the covering portion 101 at the rear end of the outer cylinder 10 is capable of containing a part of the DVI, and in order to expose (release) the remaining part of the DVI to the outside of the covering portion 101, a part of the outer peripheral portion of the covering portion 101 (a part of the surface on the opposite side to the screw member insertion portion 2) is cut into a substantially コ shape and provided with a DVI insertion portion (connector insertion portion) 103 (see fig. 3).
In preventing illegal use of the DVI by the connector locking device L, first, as shown in (1) of fig. 6, the cover portion 101 of the key cylinder 1 and the cover portion 20 of the screw member insertion portion 2 are aligned with the connection surface of the DVI and one of the screw portions S, respectively, and the cover portions 101, 20 are covered on the connection surface of the DVI and one of the screw portions S. At this time, a part of the DVI (about two thirds of the entire DVI from one end in the longitudinal direction thereof) is covered and sealed by the cover 101, and the remaining part of the DVI passes through the DVI penetration portion 103 of the cover 101 and is exposed to the outside of the cover 101. Next, the screw member 3 in the screw member insertion portion 2 is screwed into one of the screw portions S of the DVI to fix the connection surface between the key cylinder 1 and the DVI. Next, as shown in fig. 6 (2), the key 12 is inserted into the key hole 110 of the key cylinder 1 and rotated by 90 °, the lock cover 4 and the inner cylinder 11 are rotated together, and the cover 42 is rotated from the unlock position away from the opening 210 of the screw member insertion portion 2 to the lock position above the opening 210 to close the opening 210, that is, to cover the opening 210. As shown in fig. 6 (3), the key 12 is pulled out from the keyhole 110 to lock the key cylinder 1, and the lock lid 4 is locked by the locking, whereby the key cylinder 1 is locked to the DVI connection surface. As shown in fig. 6 (4), since the cover portion 42 of the lock cover 4 cannot be rotated from the lock position to the unlock position due to the above-described locking, the screw member 3 fastened to the one screw portion S of the DVI cannot be taken out, and the cover portion 101 of the key cylinder 1 is completely fixed to the connection surface of the DVI so as to cover and close the connection surface of the DVI. Therefore, since the cable-side connector cannot be inserted into the DVI, various data in the personal computer P cannot be taken out by the connection of the cable, and the DVI cannot be damaged.
Further, when the DVI is used, the key 12 is first inserted into the key hole 110 of the key cylinder 1 to unlock the key cylinder 1, thereby unlocking the lock cover 4 and the cover portion 101 of the key cylinder 1 with respect to the connection surface of the DVI. Next, the key 12 is rotated by 90 °, and the lock cover 4 is moved away from the opening 210 of the screw member insertion portion 2 to open the opening 210. Further, the screw member 3 in the screw member insertion portion 2 is taken out from the screw portion S to release the fixation of the covering portion 101 of the key cylinder 1 and the connection surface of the DVI, and then the connector locking device L is removed from the connection surface of the DVI. Thereby, the cable-side connector can be connected to the DVI.
Also, the case where the above-described connector locking device L is used for D-Sub is substantially the same.
As described above, the connector lock device L includes: a key cylinder 1 having a covering portion 101 at a rear end thereof, the covering portion covering and closing all or part of a connection surface of an equipment-side connector; a screw member insertion portion 2, the screw member insertion portion 2 being provided in a substantially cylindrical shape in parallel on an outer peripheral surface of an outer cylinder 10 of the key cylinder 1, a rear end of the screw member insertion portion 2 having a covering portion 20; a screw member 3 which is inserted and accommodated in the screw member insertion portion 2, and which can be fastened to the screw portion S of the equipment-side connector; and a lock cover 4, the lock cover 4 being operatively connected to a front end side of the key cylinder 1, the lock cover 4 being rotated about an axis of the key cylinder 1 by rotating the key 12, whereby the lock cover 4 can open and close an opening 210 of the screw member insertion portion 2.

However, two screw member insertion portions may be symmetrically provided in parallel on the outer peripheral surface of the outer cylinder 10 of the key cylinder, one screw member may be inserted into each of these screw member insertion portions, the connection surface of the equipment-side connector may be covered and closed by a covering portion at one end of the key cylinder, the two screw members may be fastened to screw portions at both ends of the equipment-side connector, and the openings of these screw member insertion portions may be covered by a cover portion of the lock cover, in which case the cover portions of the lock cover are two cover portions extending symmetrically from the cover rotating portion. This also achieves the same operational effects as those of the above-described embodiment, and a more reliable locked state of the connector locking device can be obtained.
In the connector lock device L, the outer cylinder 10 of the key cylinder 1 and the covering portion 101 at the rear end of the outer cylinder 10 are substantially cylindrical, but the outer cylinder 10 and the covering portion 101 may be each square cylindrical, or the outer cylinder 10 and the covering portion 101 may be each cylindrical matching the outer peripheral shape of the equipment-side connector. In this way, the same operational effects as those of the above embodiment can be obtained, and in particular, when the outer cylinder 10 and the covering portion 101 are formed in a tubular shape that matches the outer peripheral shape of the equipment-side connector, the appearance effect can be improved.
In the connector lock device L, the key cylinder 1 is configured as a coil spring type key cylinder, but the key cylinder 1 may be configured as another type of key cylinder such as a tumbler type (japanese patent: ピンタンブラー type). This also achieves the same operational effects as those of the above embodiment.
In the connector locking device L, the lock cover 4 is composed of the cover rotating portion 41 and the cover portion 42, the engaging recess 40 is formed on the inner peripheral surface of the cover rotating portion 41, the locking protrusion 112 is formed on the front end side of the outer peripheral surface of the inner cylinder 11 of the key cylinder 1, and the cover rotating portion 41 is operatively connected to the inner cylinder 11 on the front end side of the outer cylinder 10 of the key cylinder 1 by the engagement of the engaging recess 40 and the locking protrusion 112. However, conversely, an engagement convex portion may be formed on the inner peripheral surface of the cover rotating portion, an engagement concave portion may be formed on the front end side of the outer peripheral surface of the inner cylinder of the key cylinder, and the cover rotating portion may be operatively connected to the inner cylinder on the front end side of the outer cylinder of the key cylinder by the engagement convex portion and the engagement concave portion. This also achieves the same operational effects as those of the above embodiment.
