Description

The present disclosure relates to a power cable for a pet camera.

Conventionally, a network camera device for pet photography placed indoors is known (see, for example, Patent Document 1). This network camera device is connected to a network with a water container that allows pets to drink water, a feeding container that feeds pets, a camera unit for taking pictures of pets and acquiring pet images, and so on. Separate the network unit for data communication including transmission of pet images to the client, the control unit that controls each device unit, and at least the camera unit at a predetermined distance upward from the water container and / and the feeding container. In some embodiments, it comprises a holding portion for holding.

Japanese Unexamined Patent Publication No. 2013-22303

By the way, when the power cable used for the conventionally known AC adapter is used for the above-mentioned network camera device for pet photography (hereinafter, simply referred to as a pet camera), pets such as cats and dogs indoors. When a dog walks, flies, moves, or plays nearby, it may unnecessarily bite an electric wire. Therefore, in a pet camera, there is a possibility that the pet may not be able to continue to image the pet due to the wire being bitten by the electric wire, and the pet may be electrocuted or leaked due to the electric shock, which may lead to a fire. On the other hand, there are some that use a flexible metal tube (for example, casing tube) to protect the electric wire even if it is bitten, but since this is hard and strong, it does not bend freely, so the wiring of the electric wire I can't handle it as I expected. In addition to this, if the electric wire protected by a flexible metal tube or the like lifts the pet camera due to its hardness, and the pet camera has a mechanism for suppressing the fall due to an external force, the fall prevention function may not work. I am concerned. In addition, some pet cameras have a protective cover attached only to resin or rubber tubes, which makes wiring difficult and prevents the pet camera from lifting, but its strength is low and it is brittle. The protection was not enough.

The present disclosure has been devised in view of the conventional circumstances described above, and an object of the present disclosure is to provide a power cable for a pet camera that can ensure the sustainability of photography while activating the safety of the pet and the fall prevention structure of the pet camera. do.

The present disclosure is a power cable for a pet camera that is mounted on an installation surface and connected to a pet camera that suppresses overturning due to an external force from the side, and has a circular outer peripheral shape in which a conductor is covered with an insulating material. The electric wire has flexibility and the inner and outer peripheral shapes are formed in a circular shape. Provided is a power cable for a pet camera, comprising a coil spring having a first gap and being inserted into the inner diameter side of the tube and having a second gap on the inner diameter side to insert the electric wire.

According to the present disclosure, in the power cable for a pet camera, it is possible to ensure the sustainability of shooting while activating the safety of the pet and the fall prevention structure of the pet camera.

Hereinafter, embodiments in which the power cable for the pet camera according to the present disclosure is specifically disclosed will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanations of already well-known matters and duplicate explanations for substantially the same configuration may be omitted. This is to avoid unnecessary redundancy of the following description and to facilitate the understanding of those skilled in the art. It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

FIG. 1 is an external perspective view of the pet camera 11 to which the power cable 13 for the pet camera according to the first embodiment is connected, as viewed from the front side. The power cable for a pet camera (hereinafter, also simply referred to as a power cable) 13 according to the first embodiment is suitably used for supplying power to the pet camera 11 which is an indoor camera, for example. The target of use of the power cable 13 is not limited to the pet camera 11. That is, the power cable 13 can include all electric appliances installed in a space where pets such as dogs and cats may come into contact with the power cable 13.

Prior to the description of the power cable 13, the outline configuration of the pet camera 11 used as an example of the electric product to which the power cable 13 is connected will be described.

The pet camera 11 has a cylindrical base cabinet 17 under the upper cabinet 15. The upper cabinet 15 has an imaging unit 21 provided with a lens 19. The lens 19 is arranged on the cylindrical surface 25 of the imaging housing 23. The image pickup unit 21 is tilt-rotated by a tilt mechanism (not shown) by an angle corresponding to the size of the image pickup opening 27.

A plurality of pet detection sensors 29 are provided on the upper side surface of the upper cabinet 15. Each of the plurality of pet detection sensors 29 (for example, an infrared sensor) is connected to a control unit (not shown) provided inside the upper cabinet 15 and outputs the detected heat source position to the control unit as the pet position. .. The control unit drives a tilt motor (not shown) or a pan motor 31 (see FIG. 2) so that the pet is positioned within the imaging region of the imaging unit 21 based on the input position of the pet, and causes the upper cabinet 15 to move. The pan is rotated and the imaging unit 21 is tilt-rotated.

FIG. 2 is a cross-sectional view of a main part of the pet camera 11 to which the power cable 13 for the pet camera is connected. The pet camera 11 is mounted on an installation surface 33 (see FIG. 8) and has a suction cup unit 35 that attracts to the installation surface 33, and has a fall prevention function (fall) that suppresses a fall due to an external force from the side. Preventive structure). The base cabinet 17 has a suction cup unit 35 inward. In the pet camera 11, the base cabinet 17 is installed via the suction cup unit 35 on a flat installation surface 33 such as a chest of drawers 37 (see FIG. 8), a bookshelf, or a table top plate. In the suction cup 39 provided in the suction cup unit 35, the internal space 41 opens at the outer peripheral portion of the upper opening 43 and the outer peripheral portion of the lower opening 45. When the pet camera 11 is installed on the installation surface 33 by the user, the outer peripheral portion of the upper opening 43 of the suction cup unit 35 supports the load of the mechanical system (not shown) mounted in the pet camera 11. It is closed by the motor holder 47. The load of the mechanical portion (not shown, see above) of the pet camera 11 including, for example, the pan motor 31 is applied to the motor holder 47. In the fall prevention structure of the pet camera 11 (see above), the suction cup 39 having the upper opening 43 and the lower opening 45 is further formed by a mechanism portion (not shown, see above) on the outer peripheral portion of the upper opening 43. , The outer peripheral portion of the lower opening 45 is sealed by the installation surface 33 to function.

When the pet camera 11 is installed on the installation surface 33 and is lifted in the vertical direction by the user, the motor holder 47 that has blocked the upper opening 43 of the suction cup 39 is raised. Then, in the internal space 41 of the suction cup 39, the upper opening 43 is opened, and the internal space 41 of the suction cup 39 is no longer a closed space. Therefore, the pet camera 11 can be easily lifted.

On the other hand, the pet camera 11 receives an external force from the side to the upper cabinet 15 when the pet approaches or comes into contact with the pet. At this time, the motor holder 47 mounted on the suction cup unit 35 is tilted diagonally without being lifted in the vertical direction. When the motor holder 47 is tilted, the pet camera 11 is elastically deformed so that the outer peripheral portion of the lower opening 45 of the suction cup 39 is peeled off from the installation surface 33. This elastic deformation is a deformation that increases the volume of the internal space 41 in the suction cup 39. As a result, in the suction cup 39 in which the outer peripheral portion of the lower opening 45 and the outer peripheral portion of the upper opening 43 are closed, the internal space 41 becomes more negative pressure than the atmospheric pressure, and the suction state to the installation surface 33 is maintained. Can be maintained. As a result, the pet camera 11 can suppress the fall even if it receives a lateral external force.

FIG. 3 is an external perspective view of the pet camera 11 shown in FIG. 1 as viewed from the rear side. A power cable 13 for supplying power from the outside can be connected to the pet camera 11 having a fall prevention function. A recess 49 for connecting one terminal of the power cable 13 is formed in a part of the base cabinet 17 in the circumferential direction. A DC jack 51 is attached to one of the terminals of the power cable 13. The DC jack 51 is inserted into the DC jack insertion port 53 (see FIG. 2) arranged at the lower part of the upper cabinet 15 from the recess 49 and connected to the pet camera 11. This enables electrical conduction between the power cable 13 and the pet camera 11, so that power is supplied to the pet camera 11 via the power cable 13.

FIG. 4 is a plan view of the power cable 13. The power cable 13 has the above-mentioned DC jack 51 attached to one terminal of the cable body 55. The DC jack 51 has a jack housing 57 integrally molded with an insulating resin. The jack housing 57 projects a jack 59, which is an electrical contact portion, from the tip thereof. By inserting the jack 59 into the DC jack insertion port 53, the pet camera 11 can supply power via the power cable 13.

In the jack housing 57, a shaft-shaped electric wire lead-out portion 61 is formed in a direction orthogonal to the protruding direction of the jack 59. The electric wire 63 (see FIG. 5) connected to the jack 59 is led out from the electric wire lead-out portion 61 to the outside of the jack housing 57. In the electric wire 63 led out from the jack housing 57, the lead-out portion from the jack housing 57 is covered with the boot portion 65 integrally formed with the jack housing 57. The boot portion 65 is formed in a tapered shape having a smaller diameter in the wire lead-out direction from a tubular portion having substantially the same outer diameter as the wire lead-out portion 61 of the jack housing 57. The boot portion 65 is provided with a plurality of peripheral grooves in a multi-stage shape, so that the boot portion 65 has flexibility while increasing the tensile strength and bending strength of the electric wire lead-out portion 61.

An AC / DC conversion unit (for example, an AC adapter 67) is connected to the other terminal of the cable body 55. The AC adapter 67 has a rectangular parallelepiped adapter housing 69 made of an insulating resin. The adapter housing 69 houses a conversion circuit (not shown) inside. The electric wire 63 of the cable body 55 is connected to the secondary power supply circuit in the conversion circuit of the adapter housing 69.

The electric wire 63 is also covered with the same boot portion 65 as described above, which is integrally fixed to the adapter housing 69 even in the vicinity of the adapter housing 69. The adapter housing 69 is provided with a pair of plug terminals 71 connected to the primary circuit of the conversion circuit projecting parallel to each other on one surface orthogonal to the surface to which the electric wire 63 is connected. In the AC adapter 67, the plug terminal 71 is inserted into, for example, an outlet to which a household commercial power supply is supplied.

In the power cable 13 in which the plug terminal 71 is inserted into the outlet, the AC power input from the plug terminal 71 is converted into a DC power supply by the conversion circuit, and the power is supplied from the jack 59 to the pet camera 11.

Although the power cable 13 will be described as a cable for a secondary power supply in the first embodiment, the power cable 13 does not have a DC jack 51 or an AC adapter 67, and has other types at both ends of the cable body 55. A connector may be connected. Further, the power cable 13 can be used not only for the secondary power supply described above but also for the primary power supply by appropriately changing the specifications of the electric wire 63.

FIG. 5 is an enlarged perspective view of a main part of the cable main body 55. FIG. 6A is a cross-sectional view of the cable body 55 cut along a plane orthogonal to the longitudinal direction. FIG. 6B is a cross-sectional view of the cable body 55 cut along a plane orthogonal to the longitudinal direction during the biting operation by the pet. The cable body 55 of the power cable 13 is composed of an electric wire 63, a tube 73, and a coil spring 75.

The electric wire 63 is formed with a circular outer peripheral shape in which the conductor 77 is covered with the insulating material 79. The electric wire 63 may be formed in an outer peripheral shape other than the circular shape as long as the conductor 77 is covered with the insulating material 79. For example, the electric wire 63 may be formed with a flat outer peripheral shape in which the conductor 77 is covered with the insulating material 79. The electric wire 63 may be single-core or multi-core. The conductor 77 may be a single wire, a parallel wire, or a stranded wire. The material of the conductor 77 may be copper, aluminum, or the like. The insulating material 79 may be a fluororesin having good surface smoothness, vinyl chloride (that is, polyvinyl chloride; the same shall apply hereinafter), polyurethane, polyethylene, foamed polyethylene, or the like. In the first embodiment, the electric wire 63 has two conductors 77. In the electric wire 63, each of the conductors 77 may be covered with an inner coating, and the outer periphery thereof may be collectively covered with an insulating material 79. Further, in the electric wire 63, the outer circumference of the insulating material 79 may be further covered with an outer cover.

The tube 73 has flexibility, the inner and outer peripheral shapes are formed in a circular shape, and the electric wire 63 is inserted on the inner diameter side. As the flexible tube 73, a soft tube is particularly preferably used. Examples of the material of the soft tube include soft vinyl (PVC and the like), rubber, silicon rubber and the like.

In the first embodiment, the wall thickness of the tube 73 is set to, for example, 0.5 to 2.0 mm. The wall thickness of the tube 73 is not limited to this.

Further, in the first embodiment, the tube 73 is formed of a transparent material such as soft vinyl. The transparent material may be such that the coil spring 75 passed through the inside can be visually recognized. The tube 73 does not have to be made of a transparent material.

The coil spring 75 is formed by spirally winding an elastic wire rod 81 to form an inner and outer peripheral shape in a circular shape. The coil spring 75 has a first gap S1 (see FIG. 6A) on the outer diameter side and is inserted into the inner diameter side of the tube 73. Further, the coil spring 75 has a second gap S2 (see FIG. 6) on the inner diameter side, and the electric wire 63 is inserted through the coil spring 75. The material of the elastic wire 81 may be a spring steel material, phosphor bronze, stainless steel, or a hard resin. As an example, the coil spring 75 can have a wire diameter of φ0.3 to 2.0 mm and an outer diameter of φ4 to 10 mm. The wire diameter and outer diameter of the coil spring 75 are not limited to this.

In the first embodiment, the coil spring 75 is set to a distance at which adjacent wire rods suppress the invasion of the pet teeth 83 penetrating the tube 73 (see FIG. 6B). Adjacent elastic wires may come into contact with each other. As an example, the coil spring 75 can have an average gap between elastic wires of 0 to 5.0 mm, more preferably 0 to 1.0 mm.

In the cable body 55, the electric wire 63, the coil spring 75, and the tube 73 are arranged as concentric circles in this order from the center side. The cable body 55 is actually located inside the tube 73 where the coil spring 75 and the electric wire 63 are eccentric due to gravity or the like. The outer diameter of the electric wire 63 is D1. The coil spring 75 has an inner diameter of B2 and an outer diameter of D2. The tube 73 has an inner diameter of B3 and an outer diameter of D3.

A first gap S1 obtained by subtracting the outer diameter D2 of the coil spring 75 from the inner diameter B3 of the tube 73 is provided between the inner diameter side of the tube 73 and the outer diameter side of the coil spring 75. A second gap S2 is provided between the outer diameter side of the electric wire 63 and the inner diameter side of the coil spring 75, which is obtained by subtracting the outer diameter D1 of the electric wire 63 from the inner diameter B2 of the coil spring 75.

The first gap S1 of the cable body 55 of the power cable 13 is sufficiently deformed so that the tube 73 is crushed inward in the radial direction to form an ellipse and the coil spring 75 can be moved in the long axis direction of the ellipse. It is set at a reasonable distance.

Further, in the second gap S2 of the cable body 55 of the power cable 13, the electric wire 63 can move in the radial direction when the pet tooth 83 penetrating the tube 73 reaches the inner diameter side of the coil spring 75. Is set at a sufficient distance.

The cable body 55 of the power cable 13 is provided so that both ends of the coil spring 75 are inserted between the DC jack 51 and the AC adapter 67 by inserting the outer diameter side of the tapered tip of the boot portion 65 into the inner diameter side. Further, the power cable 13 is provided so that both ends of the tube 73 cover the outer diameter side of the coil spring 75 in which the tapered tip of the boot portion 65 is inserted on the inner diameter side and extend between the DC jack 51 and the AC adapter 67. Be done. The tube 73 may be formed with a length such that both ends thereof are not inserted into the boot portion 65.

Next, the operation of the power cable 13 for the pet camera described above will be described.

The power cable 13 for a pet camera according to the first embodiment is used for a pet camera 11 which is mounted on an installation surface 33 and suppresses a fall due to an external force from the side. The power cable 13 has flexibility with an electric wire 63 having a circular or flat outer peripheral shape in which the conductor 77 is covered with an insulating material 79, and the inner and outer peripheral shapes are formed in a circular shape, and the electric wire 63 is inserted on the inner diameter side. The tube 73 and the elastic wire 81 are spirally wound to form an inner and outer peripheral shape in a circular shape. The outer diameter side has a first gap S1 and is inserted into the inner diameter side of the tube 73, and the second gap is on the inner diameter side. A coil spring 75 having S2 and inserting an electric wire 63 is provided.

In the power cable 13 for a pet camera according to the first embodiment, the connected pet camera 11 has a suction cup unit 35 that is attracted to the installation surface 33. When the pet camera 11 receives an external force from the side by the pet, the suction cup unit 35 is attracted to the installation surface 33 and can suppress the pet camera 11 from tipping over.

The power cable 13 connected to the pet camera 11 is composed of an electric wire 63, a tube 73, a coil spring 75, a first gap S1, and a second gap S2. The conductor 77 of the electric wire 63 is covered with the insulating material 79, and the outer peripheral shape of the electric wire 63 is formed to be circular or flat.

The tube 73, which is the outermost material of the power cable 13, has flexibility, and the inner and outer peripheral shapes are formed in a circular shape. That is, the electric wire 63 is inserted into the tube 73 on the inner diameter side of the cylinder.

The coil spring 75 is arranged between the electric wire 63 and the tube 73. That is, the coil spring 75 has a first gap S1 on the outer diameter side and is inserted into the inner diameter side of the tube 73, and has a second gap S2 on the inner diameter side to insert the electric wire 63.

Therefore, the tube 73, the coil spring 75, and the electric wire 63 can be arranged in concentric circles. Actually, due to the action of gravity, the coil spring 75 may be in contact with the inner diameter side of the tube 73, and the electric wire 63 may be eccentric so as to be in contact with the inner diameter side of the coil spring 75. That is, in the power cable 13, the electric wire 63 is doubly covered and protected by the coil spring 75 and the tube 73.

An annular first gap S1 is provided between the inner diameter side of the tube 73 and the outer diameter side of the coil spring 75. The coil spring 75 inserted through the inner diameter side of the tube 73 can freely move in the radial direction by the distance of the first gap S1 until it hits the inner diameter side of the tube 73.

Further, an annular second gap S2 is also provided between the inner diameter side of the coil spring 75 and the outer diameter side of the electric wire 63. The electric wire 63 inserted on the inner diameter side of the coil spring 75 can be freely moved in the radial direction by the distance of the second gap S2 until it hits the inner diameter side of the coil spring 75.

FIG. 7 is an explanatory diagram showing the biting motion by the pet in the order of increasing damage in (A) to (E). In this power cable 13, when the outermost tube 73 is bitten by a pet from the outer diameter side (see FIG. 7A), the outer peripheral shape of the tube 73 made of a soft material is crushed and deformed into an oval or an ellipse. .. On the inner diameter side of the tube 73 deformed into an oval or ellipse, a retreat space (that is, the first gap S1) in which the coil spring 75 can be retracted (shifted or escaped) expands in the major axis direction of the ellipse or ellipse. ..

When the pet further bites the tube 73, the tip of the tooth 83 penetrates the tube 73 (see FIG. 7B). When the tooth 83 penetrating the tube 73 hits the outer diameter side of the coil spring 75, the surface of the coil spring 75 having a circular outer peripheral shape harder than the tube 73 slides with respect to the tooth 83 (see FIG. 7C). ). That is, the coil spring 75 is displaced or escapes from the tooth 83 in the first gap S1 in which the coil spring 75 is expanded. In the power cable 13, a soft material is used for the tube 73, and the outer diameter of the spring is made sufficiently smaller than the inner diameter of the tube by providing the first gap S1, so that the space for the spring to escape is expanded. Further, since the tube 73 also extends when bitten, the coil spring 75 can escape in the expanded first gap S1 (see FIG. 7 (D)).

When the pet bites more strongly and deeply, the teeth 83 penetrating the tube 73 enter between the adjacent elastic wires of the coil spring 75 (see FIG. 7E), but the coil spring 75 Since the outer diameter of the electric wire 63 is made sufficiently smaller than the inner diameter by providing the second gap S2, the electric wire 63 is displaced or escaped from the tooth 83 in the second gap S2, and the insulating material 79 is torn. And penetration is suppressed.

For example, many pets kept at home are small, such as dogs or cats, weighing 10 kg or less, and the size of the roots of the canines of small dogs or cats is about 2 to 10 mm in φ (that is, diameter). It has a pointed tip. Therefore, as shown in FIG. 6B, the pet tooth 83 penetrates the tube 73 and then bites further so that the coil spring 75 escapes to the tooth 83 when the tube 73 is extended and the tooth is deeply pierced. In order to move within 73, it is desirable that, for example, twice the length of S1 (that is, 2 × S1) is 0.3 mm or more.

Due to these actions, the power cable 13 can make the electric wire 63 less likely to be damaged and can sufficiently protect the electric wire 63 as compared with the electric wire 63 to which the protective cover of only the resin or the rubber tube is attached. As a result, in the power cable for the pet camera, it is possible to prevent the pet from being disconnected by biting the electric wire 63 and being unable to continue imaging the pet. At the same time, it is possible to suppress a situation that leads to a fire due to an electric shock of a pet or an electric leakage caused by the electric shock.

Further, in the power cable for a pet camera, since the tube 73 is a flexible tube, for example, and the coil spring 75 is formed by winding the elastic wire rod 81, it is large while suppressing the elastic restoring force at the time of bending. Curvature allows for easy bending (ie, with a small radius of curvature).

As a result, the power cable 13 is softer and easier to bend than the conventional power cable using a flexible metal tube (casing tube) or the like, so that the wiring process of the electric wire 63 becomes easy.

FIG. 8 is a cross-sectional view of a main part of the pet camera 11 connected to the conventional power cable 87 using the casing tube 85. The conventional power cable 87 using a flexible metal tube (for example, a casing tube) is hard and stiff, so that it is difficult to bend and the radius of curvature R1 tends to be large. In the conventional power cable 87, if the bent portion 89 having a large radius of curvature is forcibly bent small during the wiring process of the electric wire 63, the pet camera 11 may be tilted due to the elastic restoring force generated thereby. When such an inclination occurs in the pet camera 11, the motor holder 47 floats and opens the upper opening 43 of the suction cup unit 35, and there is a concern that the fall prevention function does not work normally.

Further, in the case of an iron tube, if the tube 73 is torn, the pet may injure the inside of the mouth at the edge of the casing tube 85. Further, the pet's tooth 83 has a sharper tip than that of a human, and when a load is concentrated on the tip of the metal casing tube 85 by biting the metal casing tube 85, the pet's tooth 83 may be damaged or broken.

FIG. 9 is a cross-sectional view of a main part of the pet camera 11 connected to the power cable for the pet camera. On the other hand, the power cable for a pet camera is more flexible and bendable than the conventional power cable 87, and the radius of curvature R2 is easily smaller than that of the conventional power cable 87 (R1> R2). In addition, the elastic restoring force that tends to return to the straight line generated at the bent portion 89 is small. Therefore, in the power cable 13, the pet camera 11 does not tilt due to the elastic restoring force generated in the bent portion 89, and the suction cup unit 35 does not open, which may hinder the expression of the fall prevention function. No. As a result, according to the power cable for the pet camera, the suction cup unit 35 can be maintained in the closed state, and the fall prevention function of the pet camera 11 can be surely exhibited.

In addition to this, unlike the casing tube 85, the coil spring 75 of the power cable 13 spirally winds a round elastic wire 81, so that there is no edge, and even if the tube 73 is torn, the pet will be injured in the mouth by the edge. Never. Further, unlike the hard metal casing tube 85, the coil spring 75 slides the elastic wire rod 81 even when chewed, so that the load is not concentrated on the tip of the tooth 83, and the pet tooth 83 is damaged or broken. Can be suppressed. As a result, the power cable for the pet camera can also protect the pet's teeth 83 as compared with the structure in which the hard metal is directly bitten.

Further, in the power cable for a pet camera, the wall thickness of the tube 73 is 0.5 to 2.0 mm.

In the power cable for the pet camera, the wall thickness of the tube 73 made of a soft tube is set in the range of 0.5 to 2.0 mm. When the wall thickness of the tube 73 is, for example, 0.5 mm or less, the tube 73 is likely to be torn when a pet chews it. On the other hand, when the wall thickness of the tube 73 is 2.0 mm or more, for example, the strength increases, but the tube 73 becomes hard, stiff, and difficult to bend. Therefore, the pet camera 11 tends to tilt due to the elastic restoring force generated in the bent portion 89. In the power cable for the pet camera, the wall thickness of the tube 73 made of a soft tube is set in the range of 0.5 to 2.0 mm, so that the pet camera 11 falls while suppressing damage when the pet bites. The prevention function can be exerted more reliably.

Further, in the power cable for a pet camera, the first gap S1 is a deformed shape in which the tube 73 is crushed inward in the radial direction to form an ellipse, and the coil spring 75 is moved to one end side in the long axis direction of the ellipse. Is the distance that can be achieved.

In this power cable for a pet camera, the tube 73 is crushed inward in the radial direction to form an oval, and the first gap S1 is set at a distance for moving the coil spring 75 in the long axis direction of the oval. There is. As a result, when the tube 73 is bitten by a pet from the outer diameter side, a retractable space in which the coil spring 75 can retract (shift or escape) can be more reliably secured.

Further, the power cable for the pet camera is set at a predetermined distance so that the adjacent wires of the coil spring 75 suppress the invasion of the pet teeth 83 penetrating the tube 73.

In the power cable for the pet camera, the adjacent wires of the coil spring 75 are set at a distance that suppresses the invasion of the pet's teeth 83. As a result, the pet teeth 83 penetrating the tube 73 are less likely to enter the inner diameter side of the coil spring 75, and the electric wire 63 can be less likely to be damaged.

Further, in the power cable for the pet camera, in the second gap S2, when the pet tooth 83 penetrating the tube 73 reaches the inner diameter side of the coil spring 75, the electric wire 63 is on one end side in the radial direction of the coil spring 75. The distance you can move to.

In the power cable for the pet camera, the second gap S2 is set at a distance that the electric wire 63 moves in the radial direction when the pet tooth 83 reaches the inner diameter side of the coil spring 75. As a result, when the pet bites more strongly and deeply, the teeth 83 penetrating the tube 73 enter between the adjacent elastic wires of the coil spring 75, but the electric wire 63 from the teeth 83 enters the second gap. The insulating material 79 can be more reliably suppressed from being torn or penetrated by shifting or escaping in S2.

Further, in the power cable for a pet camera, the tube 73 is formed of a transparent material.

In the power cable for this pet camera, the transparent material is a soft material having the transparency of visible light. That is, the coil spring 75 can be visually recognized from the outer diameter side of the tube 73. When a pet bites the tube 73 and a mark of damage (for example, a cloudy part) remains on the tube 73, the light transmission in that part changes, and the visibility of the coil spring 75 is lower than that in the part without the mark. do.

This allows the user to easily find the bite marks of the pet. Further, if the portion of the coil spring 75 corresponding to the bite mark is plastically deformed (opening between elastic wires or variation in spacing), it can be noticed that the damage is large and the coil spring 75 needs to be replaced. As a result, the safety of pets and the sustainability of photography can be ensured for a long period of time.

Therefore, according to the power cable 13 for the pet camera according to the first embodiment, it is possible to ensure the sustainability of shooting while activating the safety of the pet and the fall prevention structure of the pet camera 11.

Although various embodiments have been described above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications, modifications, substitutions, additions, deletions, and equality within the scope of the claims. It is understood that it belongs to the technical scope of the present disclosure. Further, each component in the various embodiments described above may be arbitrarily combined as long as the gist of the invention is not deviated.

The present disclosure is useful as a power cable for a pet camera that can ensure the sustainability of shooting while activating the safety of the pet and the fall prevention structure of the pet camera.
