Copper cable anti-theft mechanism

Abstract

To provide an anti-theft mechanism for a copper cable, in which a plurality of protrusions that engage with an elastic sheet are formed on the holding frame, and a plurality of protrusions protruding from the holding frame as a pressing force applying member that applies a pressing force to the elastic sheet corresponding to a cable pressing member are engaged with the elastic sheet arranged inside the holding frame and the copper wire cable, thereby preventing displacement by more strongly and closely contacting the elastic sheet arranged inside the holding frame. [Solution] A pair of holding frames 12a, 12b are provided which clamp a copper wire cable 11 from both sides, and a fastening means consisting of an appropriate device is attached to a predetermined position of the holding frames. An elastic sheet 15 is interposed between the holding frames and the copper wire cable to prevent misalignment. Furthermore, the holding frames are formed with a number of protrusions 16 which engage with the elastic sheet, so that the holding frame and the copper wire cable can be more strongly prevented from misalignment via the elastic sheet.

Description

[Technical field]

[0001] The present invention relates to an anti-theft mechanism for copper cables which is not only simple and highly innovative, but also keeps the copper cables safe and protected for a long time. [Background technology]

[0002] The trends in copper cable theft so far have been as follows: 1) Decide on a target using Google Maps etc. 2) Conduct a preliminary inspection. Before committing a crime, conduct a preliminary inspection to check the following points: Whether or not there is a security system. Is there a lot of foot traffic? Whether the power plant is well looked after by people or not. Is the cable easy to steal? Check vehicle entry / exit routes. Additionally, the following methods have also been reported: Investigate over several days and find times when no one is around. We deliberately break the fence to see how quickly they respond and decide whether to repair it or not. 3) After conducting this reconnaissance, it is believed that multiple perpetrators, including perpetrator A and perpetrator B, will break into solar system S as shown in Figure 8 and commit the crime.

[0003] Incidentally, a conventional anti-theft structure for a cable is known from Japanese Patent No. 5855309 (see Patent Document 1). This prior art is an anti-theft structure for a cable comprising a trough body, a trough lid that covers the upper part of the trough body and is fixed to the trough body, a cable arranged inside the trough body, a cable pressing member that presses the cable, and a pressing force applying member that applies a pressing force to the cable pressing member, wherein the cable pressing member is disposed between the cable and the trough lid, and the cable pressing member is an elastic member that contacts the back surface of the trough lid and the cable, and the trough lid is pressed by the pressing force applying member, thereby pressing the cable pressing member against the cable via the trough lid.

[0004] Although hard or soft cross-linked (chemically cross-linked or electron beam cross-linked) polyethylene resin foam is used as the elastic member, the reality is that this does not provide sufficient cable holding or binding power to prevent theft.

[0005] The present invention is not only a simple and highly innovative mechanism, but also aims to obtain an anti-theft mechanism for copper cables that can safely and long-term protect copper cables from theft. By improving the mechanism, it should be clearly distinguished from the above-mentioned prior art that only uses hard or soft Chinese polyethylene resin foam as an elastic member.

[0006] [Patent Document 1] Patent No. 5855309 Summary of the Invention [Problem to be solved by the invention]

[0007] The problem that this invention aims to solve is to obtain an anti-theft mechanism for copper cables that can be kept safe and for a long time as a means of preventing theft of copper cables, and the holding frame is formed with multiple protrusions that engage with the elastic sheet, so that the elastic sheet corresponding to the cable pressing member is engaged with the multiple protrusions protruding from the holding frame as a pressing force applying member that applies the pressing force, thereby enabling the elastic sheet arranged inside the holding frame to be more firmly and closely fitted to the copper wire cable, thereby preventing misalignment. [Means for solving the problem]

[0008] Therefore, the copper cable theft prevention mechanism of the present invention is characterized in that it has a pair of retaining frames that clamp the copper wire cable from both sides, and fastening means consisting of bolts and nuts are attached to both sides of the retaining frames, and an elastic sheet to prevent displacement is interposed between the retaining frames and the copper wire cable, and the retaining frames are formed with a number of protrusions that engage with the elastic sheet, so that the retaining frames and the copper wire cable are more strongly prevented from being displaced via the elastic sheet.

[0009] The copper cable theft prevention mechanism of this invention is characterized in that the elastic sheet has multiple grooves formed in the width direction, and multiple protrusions formed on the recessed surfaces of a pair of holding frames are adapted to be fitted into these grooves, so that the holding frames and copper wire cables are more strongly prevented from being displaced via the elastic sheet.

[0010] The copper cable theft prevention mechanism of the present invention is also characterized in that the holding frame is fixed in a proper position at the mounting position of the copper cable, thereby preventing the copper cable from being pulled out. Effect of the Invention

[0011] As described above, the copper cable anti-theft mechanism of the present invention has an elastic sheet interposed between the holding frame and the copper wire cable to prevent misalignment, and the holding frame is formed with a number of protrusions that engage with the elastic sheet, so that the holding frame and the copper wire cable can be more strongly prevented from being misaligned via the elastic sheet, thereby reliably preventing the copper cable from being theft-proof.

[0012] Furthermore, the present invention has the remarkable effect that the holding frame is fixed in place at the mounting position of the copper wire cable, and the copper wire cable can be reliably prevented from being pulled out. [Brief description of the drawings]

[0014] The copper cable theft prevention mechanism of the present invention is characterized in that it has a pair of retaining frames which clamp the copper wire cable from both sides, and fastening means consisting of bolts and nuts are attached to both sides of the retaining frames, and an elastic sheet to prevent displacement is interposed between the retaining frames and the copper wire cable, and the retaining frames are formed with a number of protrusions which engage with the elastic sheet, so that the retaining frames and the copper wire cable are more strongly prevented from being displaced via the elastic sheet.

[0015] The copper cable theft prevention mechanism of the present invention is also characterized in that the retaining frame is fixed in an appropriate position at the installation position of the copper wire cable within various facilities, thereby preventing the copper wire cable from being removed. EXAMPLES

[0016] FIG. 1 is a schematic cross-sectional view showing one embodiment of the copper cable anti-theft mechanism of the present invention. In FIG. 1, the copper cable theft prevention mechanism of the present invention has a pair of retaining frames 12a, 12b that clamp the copper wire cable 11 from both sides, and fastening means consisting of bolts 13 and nuts 14 are attached to both sides of the retaining frames 12a, 12b. An elastic sheet 15 to prevent displacement is interposed between the retaining frames 12a, 12b and the copper wire cable 11. Furthermore, the retaining frames 12a, 12b are formed with a number of protrusions 16 that engage with the elastic sheet 15 as shown in FIG. 4. Therefore, the retaining frames 12a, 12b and the copper wire cable 11 are formed so as to be more strongly prevented from being displaced via the elastic sheet 15. Needless to say, the holding frames 12a and 12b can be made of metal, rigid resin, or other appropriate materials. Moreover, it goes without saying that the fastening means consisting of the bolts 13 and nuts 14 attached to the holding frames 12a, 12b may be attached not only to both sides of the holding frames 12a, 12b but also to only one side.

[0017] Figure 2 shows a copper wire cable 11 stored in a bellows-shaped protective cover 21 and clamped on both sides by a pair of arc-shaped holders 22a, 22b, where Figure 2a) shows a conventional copper cable theft prevention mechanism 10, and Figure 2b) shows the copper cable theft prevention mechanism 20 of the present invention in which holding frames 12a, 12b are attached to the gaps provided between the bellows-shaped protective cover 21.

[0018] Between the bellows-like protective covers 21, the copper cable 11 is engaged with the holding frames 22a, 22b, and is firmly fixed in place to prevent theft. Although a bellows-shaped protective cover has been exemplified as the protective cover 21, a cover that does not have a bellows-shaped structure may also be used.

[0019] FIG. 3 shows the anti-theft mechanism for copper cables of the present invention, in which a) shows the holding frame when there is one copper cable 11, b) shows the holding frame when there are two copper cables 11, c) shows the holding frame when there are three copper cables 11, and d) shows the holding frame when there are more than two copper cables 11.

[0020] Next, Figure 4a) shows the details of the method of assembling the copper cable anti-theft mechanism 20. A pair of holding frames 12a, 12b that clamp the copper wire cable 11 from both sides have multiple protrusions 16 formed on the recessed surface 12c that engage with the elastic sheet 15, and these protrusions 16 engage with the elastic sheet 15 to more firmly fasten the holding frames 12a, 12b and the copper wire cable 11 via the elastic sheet 15. In addition, any suitable device can be used in place of the above-mentioned bolts 13 and nuts 14. As shown in Figure 4b), a hinge 17 made of flexible metal (spring metal) or the like can be provided on one side, and the other side can be fixed with bolts 13 and nuts 14. It is of course also possible to use any suitable fastening means in place of bolts 13 and nuts 14. Also, as shown in FIG. 4c), instead of engaging the retaining frames 12a, 12b between the bellows-shaped protective covers 21, it is also possible to firmly attach the retaining frames 12a, 12b at predetermined positions by driving stakes 18 of, for example, about 30 cm to 60 cm into the retaining frames 12a, 12b.

[0021] FIG. 5 is a schematic perspective view showing the copper cable anti-theft mechanism 20 when assembled, in which multiple protrusions 16 formed on the surfaces of the recesses 12c of the pair of retaining frames 12a, 12b engage with the elastic sheet 15, thereby more firmly fastening the retaining frames 12a, 12b and the copper wire cable 11 together via the elastic sheet 15.

[0022] FIG. 6 shows another example of an elastic sheet 21 for preventing misalignment that is interposed between the retaining frames 12a (12b). This elastic sheet 21 has a number of grooves 22 formed in its width direction, and a number of protrusions 23 formed on the surfaces of the recesses 22c of a pair of retaining frames 22a (upper part shown) and 22b are adapted to fit into these grooves 22, so that the elastic sheet 21 and the retaining frame 22a are strongly interlocked and held in place.

[0023] Incidentally, Figure 7 shows three anti-theft mechanisms 30 for the copper cables 31 assembled in parallel, and the holding frames 32a, 32b have multiple (three) grooves 33 formed in the longitudinal direction, and elastic sheets 34 are interposed in each of the grooves 33, so that the copper cables 31 are securely held. In the figure, reference numeral 35 denotes a bellows-shaped protective cover, and between these bellows-shaped protective covers 35, the copper cable 31 is firmly attached at a predetermined position via the holding frames 32a, 32b, thereby preventing theft. Of course, the protective cover 35 need not have a bellows-like structure, and may not have a bellows-like structure. [Industrial Applicability]

[0024] As described above, the present invention makes it possible to more strongly and closely fit the elastic sheet placed inside the retaining frame and the copper wire cable to prevent misalignment, thereby providing a more reliable anti-theft mechanism for copper cables using a very simple mechanism.

[0025] In addition, in the present invention, the holding frame is formed with multiple protrusions that engage with the elastic sheet, so that the multiple protrusions protruding from the holding frame, which acts as a pressing force applying member that applies the pressing force to the elastic sheet, which corresponds to the cable pressing member, can engage with each other, thereby providing an extremely strong anti-theft mechanism for copper cables.

[0026] As yet another alternative, a number of grooves are formed in the elastic sheet, and a number of protrusions formed on the recessed surfaces of a pair of holding frames are fitted into these grooves, thereby providing a very strong anti-theft mechanism for copper cables, which can more strongly prevent the holding frames and copper wire cables from shifting position via the elastic sheet.
