[0002] Wires and cables are wire products that transmit electrical energy, electrical signals and realize electromagnetic energy conversion. Cables are usually composed of a cable core that transmits power or electrical signals and a sheath that provides protection and insulation. Cables with only one cable core and a thinner diameter are usually called wires. Some wires do not have an insulating sheath and are called bare wires. The cable core in the cable is made of metal materials with good conductive properties, usually copper or aluminum.

[0003] At present, when commonly used cables are docked in cable wells, the cables are generally peeled to expose the cable core, and then the two cables are wrapped around the docking point, and then tape is wrapped around the connection part and fixed to the wall to achieve the docking of the two cables. The existing docking fixing device uses a metal material to achieve the phenomenon of powering the two cables by peeling off the shielding layer of the cable, placing the two cables on both ends of the fixing device, and then fixing the cables to the fixing device by pressing. However, when the cable is subjected to external force, due to poor connectivity between the cable and the fixing device, the cable will detach from the fixing device, resulting in a disconnection between the two cables. The two cables need to be reconnected, which increases the complexity of the work. Therefore, a cable fixing device and fixing method for cable wells are proposed to solve the above-mentioned problems. Summary of the Invention

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] Example 1

[0032] like Figures 1 to 3 As shown, the cable fixing device in the cable well provided by the present invention: the fixing device can connect the ends of two cables. In this embodiment, the two connected cables can be defined as a first cable and a second cable respectively. The first cable has multiple first cable cores 101, and the second cable has multiple second cable cores 102. It can be understood that the fixing device can connect the multiple first cable cores 101 and the multiple second cable cores 102 one by one.

[0033] The fixing device includes a base 1 fixed to the wall by a mounting member 5 and an upper shell 2 snapped onto the base 1. The mounting member 5 includes but is not limited to screws, bolts, clamping and other connection methods. A plurality of fixing seats 3 are connected to the side of the base 1 facing the upper shell 2. The number of cable cores in the two cables can be less than or equal to the number of fixing seats 3 so as to fix the positions of multiple cables. It can be understood that each fixing seat 3 corresponds to a group of first cable cores 101 and second cable cores 102.

[0034] Two symmetrically arranged positioning seats 6 are installed on the fixing seat 3, and the first cable core 101 and the second cable core 102 to be connected are respectively connected to two opposite positioning seats 6, so that the first cable core 101 and the second cable core 102 partially overlap, and a driving unit for driving the two positioning seats 6 to rotate in opposite directions is provided between the upper shell 2 and the positioning seat 6, so that the overlapping parts of the first cable core 101 and the second cable core 102 are entangled together.

[0035] Specifically, positioning protrusions 14 are connected to both sides of the base 1. Positioning grooves 23 corresponding to the positioning protrusions 14 are defined on the inner side of the upper shell 2 to secure the upper shell 2 to the base 1. Both ends of the upper shell 2 are defined with wire holes 21 corresponding to the first and second cable cores 101, 102, respectively. Support guide seats 4, connected to the first and second cable cores 101, 102, are connected to both ends of the base 1 to support the cables. The support guide seats 4 have multiple mounting slots for the cable cores to ensure the cable is highly compatible with the positioning seat 6. Both the fixing seat 3 and the positioning seat 6 are made of plastic to reduce electrical conductivity between the first and second cable cores 101, 102.

[0036] like Figure 3 As shown, the positioning seat 6 includes a lower rotating member 61 and an upper rotating member 62. The lower rotating member 61 is provided with a receiving groove 611 for placing the cable. A partition 613 is provided inside the receiving groove 611. The partition 613 divides the receiving groove 611 into a first groove 6111 and a second groove 6112. The width of the first groove 6111 is greater than the width of the second groove 6112. The first groove 6111 is connected to a winding rod 612 connected to the cable. The first cable core 101 and the second cable core 102 both pass through the second groove 6112 of one of the positioning seats 6 and are located in the first groove 6111 on the other positioning seat 6, and are connected to the winding rod 612. The lower rotating member 61 and the upper rotating member 62 are hinged on one side and fixed on the other side. The fixing method can be bolt connection, clamping, buckling, etc., so that the lower rotating member 61 and the upper rotating member 62 are opened to facilitate the installation of the cable. A rotating groove 32 is provided in the middle of the fixing seat 3, and the positioning seat 6 is rotatably installed in the rotating groove 32.

[0037] Specifically, the arc of the lower rotating member 61 is larger than the arc of the upper rotating member 62, the rotating groove 32 is adapted to the lower rotating member 61 and wraps the lower rotating member 61, and the open end of the rotating groove 32 is smaller than the diameter of the lower rotating member 61, so as to confine the lower rotating member 61 in the rotating groove 32 and prevent the lower rotating member 61 from slipping out of the rotating groove 32.

[0038] like Figure 2 and Figure 3 As shown, the driving unit includes an active rack 22 connected to the upper shell 2, and the active rack 22 is arranged along the height direction of the upper shell 2. The driving unit also includes a gear connected to the positioning seat 6, and two active racks 22 are provided. The two active racks 22 are relatively staggered and respectively engage with the two gears, so that the two active racks 22 respectively drive the lower rotating members 61 in the two gears to rotate relative to each other, thereby realizing the winding connection between the first cable core 101 and the second cable core 102.

[0039] Specifically, a movable groove 31 for accommodating the gear is provided on the fixed base 3 to facilitate the rotation of the gear on the fixed base 3. The gear includes a lower tooth part 63 connected to the lower rotating part 61 and an upper tooth part 64 connected to the upper rotating part 62. A socket 11 corresponding to the active rack 22 is provided on the base 1.

[0040] Example 2

[0041] like Figure 4 and Figure 5 As shown, the only difference between it and Example 1 is that: a positioning member 7 for installing the base 1 on the wall is connected to the base 1, and a slide 12 corresponding to the socket 11 is provided on the base 1. The positioning member 7 includes a sliding rod 71 sliding in the slide 12, and the end of the sliding rod 71 close to the positioning seat 6 is connected to a driven rack 72 engaged with the gear, and the end of the sliding rod 71 away from the positioning seat 6 is connected to a conical positioning block 73, and the side of the base 1 facing the wall is connected to an expansion sleeve 74 corresponding to the slide 12, and the expansion sleeve 74 is sleeved on the outer peripheral side of the sliding rod 71. Specifically, the outer side of the expansion sleeve 74 is connected with a barb 741, which can increase the friction between the expansion sleeve 74 and the wall, and the base 1 is connected to a slide rail 13 for limiting the driven rack 72.

[0042] When the locking cam 73 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is locked and the winch 73 is unlocked.

[0043] Example 3

[0044] like Figure 6As shown, the difference between this embodiment and the second embodiment lies in that a shielding plate 614 is connected to the facing ends of the two lower rotating members 61. The shielding plate 614 is located within the winding chamber 33 and has an arc shape. Specifically, when the two positioning seats 6 are rotated 180° or an odd multiple of 180°, the shielding plate 614 on the lower rotating member 61 is located above the rotation groove 32, forming a closed space between the shielding plate 614 and the rotation groove 32 of the fixed seat 3. This prevents arcs or sparks caused by disconnection between adjacent cables and affecting other cables.

[0045] Next, a cable fixing method according to an embodiment of the present invention will be described.

[0046] The fixing method of the cable device of the present invention comprises the following steps:

[0047] Insert the expansion sleeve 74 on the base 1 into the mounting hole on the wall;

[0048] Open the upper rotating member 62 and control the corresponding cable cores of the two cables to be connected to enter the first grooves 6111 of the two positioning seats 6 from the second grooves 6112 at the opposite outer ends of the two positioning seats 6, and then wind the first cable core 101 and the second cable core 102 on the winding rod 612;

[0049] The upper shell 2 is controlled to gradually approach the base 1. During this process, the active rack 22 in the upper shell 2 engages with the gear on the positioning seat 6, thereby driving the two symmetrically arranged positioning seats 6 to rotate in opposite directions, so that the overlapping parts of the two cable cores on the two positioning seats 6 are entangled, thereby realizing electrical connection between the two cable cores;

[0050] When the overlapping parts of the two cable cores are wound, the length of the middle part of the cable core increases, causing the two ends of the cable core to move due to the winding effect. The overlapping parts of the two cable cores located on the two positioning seats 6 are separated by the partition plate 613 to prevent the two cable cores located on the positioning seats 6 from moving and causing contact between the two cable cores.

[0051] As the gear rotates, the gear drives the driven rack 72 to move toward the side of the base 1 away from the wall, indirectly driving the conical positioning block 73 into the expansion sleeve 74, so that the expansion sleeve 74 is fixed in the mounting hole on the wall;

[0052] When the upper shell 2 is separated from the base 1, the active rack 22 on the upper shell 2 and the gear on the positioning seat 6 rotate again, causing the two positioning seats 6 to rotate relative to each other, separating the winding part between the first cable core 101 and the second cable core 102, thereby disconnecting the power between the two cables and facilitating maintenance or repair of the fixing device.
