The cable body 1 connection pull-off force reaches 310N, and the crimping resistance is less than 135μΩ, which meets the standard requirements. ;
[0051] like Fig.10 and Fig.11 As shown, as an optimization of the embodiment, taking into account the tight fit between the extrusion plate 26 and the cable body 1, a first semicircular groove 31 is provided on the side of the extrusion plate 26, and the first semicircular groove 31 is adapted to the wire stripping end 2 of the cable body 1, thereby ensuring the tight fit between the extrusion plate 26 and the cable body 1, and having a good anti-loosening effect; the first semicircular groove 31 is provided with first serrated grooves 32 arranged at equal intervals, and the first serrated groove 32 is composed of a first straight line segment 33 and a first slope segment 34, and the first slope segment 34 forms a barb-like extrusion with the wire stripping end 2 of the cable body 1, thereby further improving the loosening performance of the cable body 1.

[0053] like Fig.14 and Fig.15As shown, as an optimization of the embodiment, considering that the shell 4 suspends the two cable bodies 1 in the air after docking, and the outdoor wind is strong, it will cause continuous friction between the cable body 1 and the shell 4, which may easily cause damage to the outer skin end 3 of the cable body 1. The bottom surface of the shell 4 is bonded with a glue layer 39, and an easy-to-tear film 40 is pasted on the glue layer 39. The operator tears off the easy-to-tear film 40, and the exposed glue layer 39 can be used to paste the shell 4 on the back of the photovoltaic panel, so that the position of the cable body 1 is stable, and the friction between the cable body 1 and the shell 4 is avoided.
[0054] like Fig.16 and Fig.17 As shown, as an optimization of the embodiment, taking into account the waterproof performance of the first cover plate 13 and the second cover plate 30, a sealing ring groove 41 is opened on the first cover plate 13 and the second cover plate 30, and the shape of the sealing ring groove 41 is rectangular. A sealing rubber gasket 42 is installed in the sealing ring groove 41, and the sealing rubber gasket 42 improves the waterproof performance of the installation of the first cover plate 13 and the second cover plate 30.
[0055] like Figure 18~Figure 21 As shown, as an optimization of the embodiment, considering the waterproof performance of the outer skin end 3 of the cable body 1 in the tapered hole section 6, a pressing sleeve 43 is inserted in the tapered hole section 6, the pressing sleeve 43 is a circular ring structure, the material of the pressing sleeve 43 is a rubber material, the pressing sleeve 43 is used to sleeve on the outer skin end 3 of the cable body 1, the outer side wall of the pressing sleeve 43 is provided with an annular slope surface 44, the annular slope surface 44 of the pressing sleeve 43 is provided with U-shaped notches 45 arranged at equal angles, and the number of the U-shaped notches 45 is up to The outer wall of the pressing sleeve 43 is provided with stress grooves 46 arranged at equal angles, the stress grooves 46 do not penetrate the inner wall of the pressing sleeve 43, the number of the stress grooves 46 is at least 10, and the pressing sleeve 43 is provided with an annular groove 47 connected to the stress grooves 46; the tapered hole section 6 is threadedly connected with a pressing ring 48, the pressing ring 48 is a tubular structure, the outer wall of the pressing ring 48 has an outer folded edge 49, and a screw groove 50 is provided on the outer folded edge 49, and the pipe mouth of the pressing ring 48 is a rounded structure to avoid the pressing ring 4 The sharp edge of 8 wears the cable body 1, and the inner diameter of the pressing ring 48 is larger than the inner diameter of the pressing sleeve 43. By rotating the pressing ring 48, the pressing sleeve 43 continues to move toward the tapered hole section 6, and then the annular slope surface 44 of the pressing sleeve 43 is tightly stuck in the tapered hole section 6. At this time, the gap of the U-shaped notch 45 becomes smaller, and the pressing ring 48 continues to be rotated to deform the annular groove 47 of the pressing sleeve 43, and the pressing sleeve 43 protrudes inward and squeezes the outer skin end 3 of the cable body 1 to form an annular sealing structure, which prevents the entry of rainwater and has a certain anti-slip effect. A clamping position is formed at the outer skin end 3 of the cable body 1, and when the pressing ring 48 is rotated, the pressing sleeve 43 only produces a longitudinal displacement, and the pressing sleeve 43 will not drive the outer skin end 3 of the cable body 1 to rotate, thereby ensuring the service life of the cable body 1. If the outer skin end 3 rotates, torque will be concentrated on the cable body 1. If it is blown and swung by the wind for a long time, the stripping end 2 of the cable will break, which is similar to applying a torque to the copper wire, which will break the copper wire.
[0056] like Figure 22~Figure 26 As shown, as an optimization of the embodiment, considering that the extrusion plate 26 can only limit its displacement from the inner side of the cable body 1, in order to improve the anti-slip performance of the cable body 1, a countersunk hole 51 is opened on the connecting groove 10, and the countersunk hole 51 is preferably located in the middle of the shell 4.

The conduit 53 is provided with a first square tube 59, which is connected to the conduit 53. A rotating rod 60 is rotatably connected to the first square tube 59. The upper end of the rotating rod 60 extends outside the second cover plate 30. The upper end of the rotating rod 60 is connected to a hand screw head 6 1; The side wall of the rotating rod 60 located on the first square tube 59 is connected to a hinge seat 62; The hinge seat 62 is rotatably connected to a first rotating shaft 63, and a push tongue 64 is installed on the first rotating shaft 63, and the push tongue 64 is used to insert the annular tooth groove 56, thereby pushing the push rod 54 to move; The conduit 53 has a second square tube 65, and the second square tube 65 is connected to the conduit 53; The second square tube 65 is rotatably connected to a second rotating shaft 66, and a triangular block 67 is installed on the second rotating shaft 66, and the second rotating shaft 66 is located at the waist of the triangular block 67, One corner of the triangular block 67 is adapted to the annular tooth groove 56, and the triangular block 67 plays a non-return role; a bearing plate 68 is installed on the second square tube 65, and a spring sheet 69 is installed on the bearing plate 68, and the spring sheet 69 is against the triangular block 67; the driving rod 60 is rotated by a certain angle, so that the push tongue 64 pushes the top rod 54 to move, and the top rod 54 can be quantitatively extended to ensure that the second conductive strip 11 moves the optimal distance, and then the first conductive strip 9 pulls the stripping end 2 of the cable body 1, so the cable body 1 cannot be loosened.
[0057] like Figure 27~Figure 29As shown, as an optimization of the embodiment, in order to improve the anti-slip performance of the cable body 1, a blind hole 70 is opened on the top surface of the shell 4, and the number of the blind holes 70 is 2, and the two blind holes 70 are symmetrically arranged. The blind hole 70 vertically penetrates the cable hole 5, and the blind hole 70 is located between the strip groove 8 and the tapered hole section 6 of the cable hole 5; a first clamping column 71 is slidably connected in the blind hole 70, and the first clamping column 71 is a T-shaped rotating part, and the large diameter section of the first clamping column 71 is provided with a first arc groove 72; the small diameter section of the first clamping column 71 is slidably connected to the second clamping column 73, and the second clamping column The shape of 73 is a circular tube.
