Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0020] like Figs. 1 to 4 As shown, the optical cable junction box with overhead mounting brackets is used to clamp and fix the cable to the overhead line 1, achieving a fixed connection between the two and thus preventing relative swaying. Specifically, it includes a junction box body 2, the structure of which is well known to those skilled in the art and will not be described in detail here. The junction box body 2 is connected to the overhead mounting brackets. To ensure the stability of the junction box body 2 during overhead installation, it is preferable to have at least two overhead mounting brackets evenly distributed on the junction box body 2.

[0021] The overhead mounting bracket includes an overhead mounting plate 3, one end of which is connected to the junction box body 2, and the other end of the overhead mounting plate 3 is provided with an overhead mounting fastener. A connecting through hole 4 is provided through the overhead mounting plate 3, which, in conjunction with bolts, enables a detachable connection between the overhead mounting plate 3 and the junction box body 2. The two can be assembled on-site for easy storage of both the junction box body 2 and the overhead mounting plate 3. Depending on installation requirements, the overhead mounting plate 3 can be configured as an inverted L-shaped plate.

[0022] The overhead mounting fastener has a wire passage gap 5 for cooperating with the overhead line 1. The overhead mounting plate 3 and the overhead mounting fastener are equipped with an overhead mounting locking component. The overhead mounting plate 3, the overhead mounting fastener, and the overhead mounting locking component cooperate to realize the overhead connection between the junction box body 2 and the overhead line 1.

[0023] The overhead hanging locking piece comprises a locking bolt 6 and a locking nut 7 used in cooperation, the locking bolt 6 is sleeved with a square bolt block 8, the bolt block 8 can be fixed on the locking bolt 6 or detachably assembled on the locking bolt 6, the bolt block 8 is provided with a square hole 9 matched with the bolt block 8, the bolt block 8 can prevent the relative rotation between the locking bolt 6 and the overhead hanging plate 3 and the overhead hanging fastener, thereby eliminating the loosening of the locking bolt 6 due to long use time and shaking, eliminating the hidden danger of the joint box body 2 falling and making the hanging more safe and reliable.

[0024] The overhead hanging fastener comprises oppositely arranged hanging fastener inner plates 10 and hanging fastener outer plates 11, the opposite surfaces of the hanging fastener inner plates 10 and the hanging fastener outer plates 11 are respectively formed with wire passing grooves 12, the wire passing grooves 12 are located below the overhead hanging locking piece, the two wire passing grooves 12 are enclosed to form the wire passing gap 5, and the wire passing grooves 12 are gradually deepened from the upper layer to the middle layer. With the cooperation of the locking bolt 6 and the locking nut 7, the two inclined groove walls of the wire passing groove 12 can clamp the overhead line 1, the relative fixed assembly between the overhead hanging device, the joint box body 2 and the overhead line 1 is realized, and the relative swinging between the joint box body 2 and the overhead line 1 in the front and back directions is eliminated.

[0025] The upper end side of the hanging fastener inner plate 10 is provided with an assembly butt joint table 13, and the upper end of the hanging fastener outer plate 11 abuts against the assembly butt joint table 13. When the hanging fastener inner plate 10 and the hanging fastener outer plate 11 are assembled and butt jointed, the hanging fastener outer plate 11 can be quickly assembled and positioned, thereby helping to improve the assembly efficiency.

[0026] The opposite surfaces of the hanging fastener inner plate 10 and the hanging fastener outer plate 11 are respectively formed with lightening grooves 14, and the overhead hanging locking piece penetrates the lightening grooves 14. The hanging fastener inner plate 10 and the hanging fastener outer plate 11 which need to be operated on site are lighter in weight and more convenient for high-altitude assembly. Moreover, when assembling, the locking bolt 6 is blocked by the cooperation of the square hole 9 and the bolt block 8, so that the locking nut 7 can be rotated by means of an electric wrench, and the assembly can be realized without manually blocking the locking bolt 6, thereby helping to further improve the assembly efficiency.
