Description

Technical Field

[0001] The utility model relates to the technical field of wire clamps, in particular to a flat wire clamp which is easy to install. Background Art

[0002] Wire clamps are one of the commonly used devices in power systems. Currently common wire connectors include parallel groove wire connectors, wedge-shaped wire connectors, etc. Among them, the parallel groove wire connector directly clamps the wires through bolts and clips, and the flat wire clamp is a device for fixing circuit lines.

[0003] After searching, a Chinese patent discloses a wire clamp that is easy to install (authorization announcement number CN218958433U). The patented technology includes a wire clamp base plate, a combing mechanism, an assembling structure and an attachment structure. The combing mechanism is located at the front end of the wire clamp base plate, the assembling structure is located at the outer end of the combing mechanism, and the attachment structure is located at the bottom end of the wire clamp base plate. The combing mechanism includes a mounting plate, an arc-shaped fixed wire clamp, an arc-shaped combing wire clamp, and an opening. The wire clamp, which is easy to install, is equipped with a combing mechanism. The arc-shaped combing wire clamp is convenient for fixing through the mounting plate, so as to facilitate the subsequent clamping of the wire harness. The arc-shaped fixed wire clamp clamps and fixes the wire harness, and the arc-shaped combing wire clamp clamps the root wire of the wire harness, so as to facilitate the individual clamping of each cable in the wire harness and the combing of the wire harness. The opening one facilitates the wire harness to enter the interior of the arc-shaped fixed wire clamp, so that the arc-shaped fixed wire clamp clamps and fixes the wire harness, so as to avoid the displacement of the wire harness during the subsequent installation of the connecting cable and affect the installation of the cable. However, in the actual application process of this patented technology, the wire harness is fixed by the arc-shaped fixed wire clamp, and the single cable is fixed by the arc-shaped combing wire clamp. Because the arc-shaped combing wire clamp is fixed on the bottom plate of the wire clamp in an array, when the cable inside the arc-shaped combing wire clamp is pulled arbitrarily, the cable and the arc-shaped combing wire clamp rub violently, which can easily cause damage to the cable sheath.

[0021] Through the above technical solution, the cable is placed between the two second clamping grooves 18, and the positioning ring 10 is pressed downward to move the sliding shaft 9 downward, driving the lower pressure plate 2 to move downward, and the lower pressure plate 2 is fixed by the positioning assembly. At this time, the two second clamping grooves 18 are connected, and the positioning block 19 enters the positioning groove 20 to clamp and fix the cable to prevent multiple cables from being entangled with each other. When the cable is pulled arbitrarily for wiring, the upper clamp block 11 and the lower clamp block 12 rotate with the cable to prevent the cable sheath from being worn. The upper clamp block 11 and the lower clamp block 12 rotate while driving the limit ring 13 to rotate. The limit ring 13 is limited by the set limit assembly to fix the pulled cable.

[0022] Specifically, the positioning assembly includes a card block 5, which is arranged inside the fixed frame 1 and is slidably connected to the fixed frame 1. A second spring 6 used in conjunction with the card block 5 is arranged inside the fixed frame 1. A push rod 8 is slidably connected inside the fixed frame 1 and located above the card block 5. A slide plate 7 is fixedly connected to the top of the push rod 8. The slide plate 7 is slidably connected to the fixed frame 1. An inclined groove used in conjunction with the push rod 8 is opened on the top of the card block 5.

[0023] Through the above technical solution, the lower pressure plate 2 is pressed downward, and the lower pressure plate 2 presses against the inclined surface at one end of the block 5, pushing the block 5 to move and pressing the second spring 6. When the lower pressure plate 2 moves to the bottom of the block 5, under the action of the second spring 6, the block 5 is reset to fix the position of the lower pressure plate 2. At this time, the upper clamping block 11 is docked with the lower clamping block 12 to fix the cable. When removing the cable, the slide plate 7 is pressed to drive the push rod 8 to move downward. The push rod 8 presses against the inclined groove at the top of the block 5, which can push the block 5 to move and separate from the lower pressure plate 2.

[0024] Specifically, the limit assembly includes a limit block 14, which is arranged inside the positioning ring 10 and is slidably connected to the positioning ring 10, the outer wall of the upper clamping block 11 is fixedly connected to the limit ring 13, the limit ring 13 is rotatably connected to the positioning ring 10, and the outer wall of the limit ring 13 is equidistantly provided with limit grooves 15 for cooperating with the limit block 14, one end of the limit block 14 is fixedly connected to a slide rod 16, the slide rod 16 is slidably connected to the positioning ring 10, and the outer wall of the slide rod 16 is provided with a third spring 17.

[0026] Specifically, the limiting block 14 is configured as a trapezoidal structure.

[0027] Through the above technical solution, the limiting ring 13 is limited by providing the limiting block 14 with a trapezoidal structure and inserting the third spring 17 into the limiting groove 15 .

[0028] Specifically, a first spring 3 is disposed at the bottom of the lower pressing plate 2 .

[0029] Through the above technical solution, the lower pressure plate 2 will compress the first spring 3 after moving downward, and the set first spring 3 can also help the lower pressure plate 2 to reset.

[0030] Specifically, the bottom of the lower pressing plate 2 and the inner wall of the fixing frame 1 are both provided with a first clamping groove 4 .

[0031] Through the above technical solution, the wiring harness integrated with multiple cables is placed between the two first clamping grooves 4, and after the lower pressing plate 2 is moved downward, the lower pressing plate 2 is fixed by the positioning assembly to clamp the wiring harness.

[0032] When in use, when clamping the cables, put the cables between the two second clamping grooves 18, press the positioning ring 10 downward, move the sliding shaft 9 downward, drive the lower pressure plate 2 to move downward, the lower pressure plate 2 presses against the inclined surface at one end of the clamping block 5, pushes the clamping block 5 to move, and compresses the second spring 6. When the lower pressure plate 2 moves to the bottom of the clamping block 5, under the action of the second spring 6, the clamping block 5 is reset to fix the position of the lower pressure plate 2. At this time, the upper clamping block 11 and the lower clamping block 12 are docked to fix the cables to prevent multiple cables from getting entangled with each other. When the cables are pulled arbitrarily for wiring, the upper clamping block 11 and the lower clamping block 12 rotate with the cables, thereby preventing the cable sheath from being worn. The upper clamping block 11 and the lower clamping block 12 rotate while driving the limit ring 13 to rotate. The limit block 14 is pushed into the limit groove 15 by the third spring 17, and the limit ring 13 is limited to prevent the upper clamping block 11 and the lower clamping block 12 from rotating at will after rotation, so as to fix the pulled cable, and place the wiring harness integrated with multiple cables between the two first clamping grooves 4. After moving the lower pressure plate 2 downward, the lower pressure plate 2 is fixed by the positioning assembly, so as to clamp the wiring harness. When it is necessary to remove the cables and wiring harness, the slide plate 7 is pressed to drive the push rod 8 to move downward. The push rod 8 is pressed against the inclined groove at the top of the clamping block 5, so as to push the clamping block 5 to move and detach from the lower pressure plate 2. After losing the limit of the clamping block 5, under the action of the first spring 3, the lower pressure plate 2 can be pushed to move upward, and then the upper clamping block 11 can be moved upward, so as to facilitate the removal of the cables and wiring harness.
