Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment for power supply installation, and in particular to a cable termination fastening device. Background Technology

[0002] When connecting the cable to the power supply box, the cable inserted into the power supply box needs to be bent, and then the wires inside the cable are connected to each circuit switch. Because the cable is thick, it is not easy to bend and requires a lot of force. At the same time, when bending the cable, the cable needs to be repeatedly rubbed against the metal part of the cable insertion port of the power supply box. The cable sheath is easily scratched by the metal part of the power supply box. When connecting the wires inside the cable to the circuit switches, one hand needs to hold the cable and the other hand needs to connect the circuit switch. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a cable terminal fastening device. This invention uses a fixing mechanism to fix the position of the cable, avoiding friction between the cable sheath and the metal sheet at the cable insertion port of the power supply box. The tilt adjustment mechanism adjusts the degree of bending of the cable in the power supply box and fixes the bending angle to prevent the cable from changing its original angle when connecting to the circuit switch. The fine-tuning mechanism fine-tunes the bending angle of the cable, facilitating the connection between the cable and the circuit switch.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution: A cable termination fastening device includes a main frame, a fixing mechanism installed on the fixed end of the main frame, and an angle adjustment mechanism and a fine-tuning mechanism installed on the flip end of the main frame. The fine-tuning mechanism is located below the angle adjustment mechanism. The angle adjustment mechanism adjusts the overall bending degree of the main frame, and the fine-tuning mechanism fine-tunes the bending angle of the cable.

[0005] The main frame includes a first housing, a connector, and a second housing, which are connected to each other via the connector.

[0006] The first housing has equidistantly arranged threaded grooves on its shell wall, and a rotating groove is provided at the top of the first housing.

[0007] The fixing mechanism includes a first screw, a rotating ring, a contact plate, and a bevel gear. The first screw is equidistantly arranged in the threaded grooves on the first housing and threadedly connected. The bevel gear is equidistantly arranged on the inner wall of the first housing and rotatably connected. The bevel gear is threadedly connected to the first screw, and a contact plate is rotatably connected to one end of the first screw located inside the first housing. The rotating ring is located in the rotating groove on the first housing and rotatably connected. The rotating ring is meshed with the bevel gear.

[0008] The bevel gear is also provided with a threaded groove at the middle position, and the threaded groove on the bevel gear corresponds to the position of the threaded groove on the first housing.

[0009] The inner wall of the rotating ring is provided with bevel gear teeth arranged at equal intervals, and the rotating ring is connected to the bevel gear through the meshing of the bevel gear teeth.

[0010] The tilt adjustment mechanism includes a second screw, a push plate, an adjustment plate, and a positioning frame. The second screw is located on the second housing and is threadedly connected, and the push plate is rotatably connected to one end of the second screw inside the second housing. The positioning frame is located on the inner wall of the first housing and is fixedly connected, and the adjustment plate is rotatably connected between the positioning frame and the push plate.

[0011] The second screw is located on the opposite side of the connector.

[0012] The fine-tuning mechanism includes a third screw and a push plate. The third screw is located on the second housing and is threadedly connected, and the push plate is rotatably connected to one end of the third screw inside the second housing.

[0013] The push plate is located on the lower side of the push plate and is not in contact with it.

[0014] Due to the adoption of the above technical solution, the present invention has the following beneficial effects: The cable termination fastening device of this invention fixes the position of the cable through a fixing mechanism to prevent the cable sheath from rubbing against the metal sheet at the cable insertion port of the power supply box. The tilt adjustment mechanism adjusts the degree of bending of the cable in the power supply box and fixes the bending angle to prevent the cable from changing its original angle when connecting to the circuit switch. The fine adjustment mechanism finely adjusts the bending angle of the cable to facilitate the connection of the cable to the circuit switch. Attached Figure Description

The fine adjustment mechanism 4 is located below the angle adjustment mechanism 3. The angle adjustment mechanism 3 adjusts the overall bending degree of the main frame 1, and the fine adjustment mechanism 4 finely adjusts the bending angle of the cable.

[0018] The main frame 1 includes a first housing 101, a connector 102, and a second housing 103, which are connected by the connector 102.

[0019] The shell wall of the first housing 101 is provided with threaded grooves arranged at equal intervals, and the top of the first housing 101 is provided with a rotating groove.

[0020] The fixing mechanism 2 includes a first screw 201, a rotating ring 202, a contact plate 203, and a bevel gear 204. The first screw 201 is equidistantly arranged in the threaded grooves on the first housing 101 and threadedly connected. The bevel gear 204 is equidistantly arranged on the inner wall of the first housing 101 and rotatably connected. The bevel gear 204 is threadedly connected to the first screw 201. The contact plate 203 is rotatably connected to one end of the first screw 201 located inside the first housing 101. The rotating ring 202 is located in the rotating groove on the first housing 101 and rotatably connected. The rotating ring 202 is meshed with the bevel gear 204.

[0021] The bevel gear 204 is also provided with a threaded groove at the middle position, and the threaded groove on the bevel gear 204 corresponds to the threaded groove on the first housing 101. The bevel gear 204 is driven to rotate by the rotating ring 202, and the rotation of the bevel gear 204 drives the first screw 201 to move inward or outward at the same time.

[0022] The inner wall of the rotating ring 202 is provided with bevel gear teeth arranged at equal intervals, and the rotating ring 202 is connected to the bevel gear 204 through the bevel gear teeth.

[0023] The tilt adjustment mechanism 3 includes a second screw 301, a push plate 302, an adjustment plate 303, and a positioning frame 304. The second screw 301 is located on the second housing 103 and is threadedly connected. The push plate 302 is rotatably connected to one end of the second screw 301 inside the second housing 103. The positioning frame 304 is located on the inner wall of the first housing 101 and is fixedly connected. The adjustment plate 303 is rotatably connected between the positioning frame 304 and the push plate 302.

[0024] The second screw 301 is located on the opposite side of the connector 102.

[0026] The push plate 402 is located below the push plate 302 and is not in contact with it.

[0027] In the cable termination fastening device described above, during use, the operator inserts the main frame 1 into the cable insertion port of the power supply box and inserts the cable into the main frame 1. Rotating the rotating ring 202 causes the bevel gear 204 to rotate, and the bevel gear 204, through its threaded groove, moves the first screw 201, causing the contact plate 203 on the first screw 201 to contact the cable, thus fixing the cable's position. The operator then rotates the second screw 301, controlling the movement distance of the push plate 302. The movement of the movable plate 302 controls the tilt of the adjusting plate 303. By changing the tilt of the adjusting plate 303, the opening degree of the angle between the first housing 101 and the second housing 103 is controlled. The third screw 401 is rotated so that the push plate 402 on the third screw 401 comes into contact with the cable. By changing the opening degree, the tilt degree of the second housing 103 is controlled. The second housing 103 changes the bending degree of the cable by pushing the plate 402, and the bending degree of the cable is finely adjusted by the third screw 401, making it convenient for the staff to connect the cable to the circuit switch.
