[0032] In order to make the technical means, creative characteristics, achieve purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0033] As Figure 1 Shown, a kind of optical cable clamp, including line clamp main body 1, the line clamp main body 1 is through and is provided with slot 101, the line clamp main body 1 side is provided with mounting through hole 102;Bolt 2, is inserted in the slot 101 of the line clamp main body 1;Square hook 5, is set in the mounting through hole 102.

[0034] The whole clip is used by overlapping the optical cable 4 on the plug 2, then inserting the plug 2 into the larger opening of the slot 101, so that the optical cable 4 is clamped between the inner wall of the clip body 1 and the two sides of the plug 2, and by applying a certain pressure to the plug 2, the plug 2 is moved towards the smaller opening of the slot 101, thereby realizing the fixation of the optical cable 4.

[0035] The square hook 5 is used in cooperation with the clip body 1, after the clip body 1 and the plug 2 fix the optical cable 4, the whole clip body 1 is hung to the fixed point through the square hook 5. The setting of the square hook 5 makes the clip body 1 can be hung in more point, it will not be difficult to hang due to the shape of the clip body 1 itself, which is convenient for the wiring personnel to install the clip body 1.

[0036] Further, as shown in Figure 2 and Figure 3 The whole square hook 5 is an open loop, the two ends of the opening are bent into a first end portion 501 and a second end portion 502, the first end portion 501 passes through the mounting hole 102 and is overlapped with the second end portion 502 to form a locking position, the first end portion 501 of the square hook 5 can keep the distance between the opening and the clip body 1 less than the diameter of the square hook 5 under tension.

[0037] In this embodiment, after the first end portion 501 and the second end portion 502 of the square hook 5 are overlapped, when the square hook 5 is pulled, the first end portion 501 can move towards the clip body 1, so that the gap between the bent end of the first end portion 501 and the clip body 1 is reduced to less than the diameter of the square hook 5, thereby further limiting the second end portion 502 in the inner ring formed by the bending of the first end portion 501, preventing the second end portion 502 from being pulled out from the gap between the first end portion 501 and the clip body 1.

[0038] Further, the mounting hole 102 is a long slot shape, and the length of the mounting hole 102 is equal to the outer diameter width of the first end portion 501 of the square hook 5. By controlling the shape of the mounting hole 102, after the first end portion 501 of the square hook 5 is inserted into the mounting hole 102, the square hook 5 is rotated to the tension direction, at this time, the bent section of the first end portion 501 and the long slot-shaped mounting hole 102 are overlapped.

[0039] Specifically, in the state that the square hook 5 is pulled, the first end portion 501 and the second end portion 502 are both pulled away from the wire clamp body 1, so that the first end portion 501 is moved away from the installation hole 102, and because the curved end of the first end portion 501 is staggered with the long slot-shaped outlet of the installation hole 102 in the pulled state, the first end portion 501 cannot continue to move away from the installation hole 102 after the first end portion 501 is moved to the position where the first end portion 501 is close to or close to the wire clamp body 1, thereby preventing the first end portion 501 from being separated from the installation hole 102. Moreover, after the first end portion 501 is moved away from the installation hole 102, the gap between the curved end of the first end portion 501 and the wire clamp body 1 is smaller, so that the diameter of the square hook 5 is larger than the gap, thereby preventing the second end portion 502 from being separated from the gap.

[0040] Further, as shown in Figure 3 , the angle of the corner point of the first end portion 501 of the square hook 5 is less than ninety degrees, and the corner point abuts against the entrance of the installation hole after the square hook 5 is installed on the wire clamp body 1. The smaller angle of the corner point enables the first end portion 501 to be better inserted into the installation hole 102, thereby reducing the risk of disengagement.

[0041] Further, the two ends of the installation hole 102 extend outwardly to form a boss 103, which can effectively increase the overall strength of the installation hole 102.

[0042] The bending angle of the second end portion 502 is greater than ninety degrees. The inner semicircular arc formed after the first end portion 501 is bent is less than one hundred and eighty degrees. This makes the overlap between the first end portion 501 and the second end portion 502 more compact.

[0043] The hanging end of the square hook 5 is in the shape of a circular arc. When the square hook 5 is hung, the contact point can slide to the middle of the circular arc, so that the stress point of the square hook 5 and the stress point of the wire clamp body 1 are in the same direction.

[0044] In one embodiment, as shown in Figure 3 , the longer side of the square hook 5 is provided with an arc corner 503 bent inwardly. The arc corner 503 can play a certain buffering role when the square hook 5 is pulled, preventing the square hook 5 from being damaged due to too long pulling distance.

[0045] In one embodiment, as shown in Figure 4 , two rows of parallel clamping blocks 3 are arranged on the left and right inner sides of the insertion slot 101 for clamping the optical cable 4. One corner of the clamping block 3 is protruding and abuts against the outer surface of the optical cable 4 when clamping the optical cable 4.

[0046] In the embodiment, the card block 3 is in the shape of a triangular pyramid, the tip of the triangular pyramid is directed to the middle of the slot 101, a plurality of card blocks 3 are connected head to tail and arranged on the inner wall of the slot 101, the triangular pyramid-shaped card blocks 3 are head to tail almost spliced into a row, the contact points between the card blocks 3 and the optical cable are increased, the clamping force of the optical cable is more stable, and meanwhile, the triangular pyramid shape makes the whole clamping main body 1 more convenient to be injection molded.

[0047] By arranging two rows of card blocks 3 on both sides in the slot 101, the clamping force can be more evenly dispersed, the optical cable 4 is firmly fixed, and the risk of loosening or slipping is reduced.

[0048] In the embodiment, as shown in Figure 5 the optical cable 4 is clamped on the two rows of card blocks 3, the outer surface of the optical cable 4 abuts against the protruding points on the card blocks 3, so that, after the plug-in pin 2 presses the optical cable 4, the position of the optical cable 4, at which the outer surface abuts against the protruding points on the card blocks 3, is deformed, the protruding points on the card blocks 3 extrude the outer skin of the optical cable 4, and a wavy clamping surface is formed. By clamping the optical cable 4 by the card blocks 3, the axial movement of the optical cable 4 when clamped can be prevented, and the stability of the clamping of the optical cable 4 by the wire clamp main body 1 is improved.

[0049] In an embodiment, the card block 3 can be in the shape of a square or a circle, the card blocks 3 are arranged in an equidistant array, and the distance between adjacent card blocks 3 is greater than or equal to zero. The greater the distance between the card blocks 3, the greater the wave amplitude of the wavy clamping surface formed.

[0050] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
