DETAILED DESCRIPTION
[0022] The bridge card of the present invention is described in detail below with reference to the accompanying drawings.
[0023] like Figures 1 to 5 As shown, a bridge wiring card includes a lower cover 1, two upper covers 2 and two springs 3. A partition 4 is provided in the lower cover 1. The partition 4 is arranged in the middle of the lower cover 1 and is arranged in the left and right directions. The two springs 3 are arranged on the front and back sides of the partition 4. The partition 4 separates the two springs 3 to prevent the two springs 3 from contacting each other and causing a short circuit. The material used for the spring 3 is the same as the spring material of the line card in the prior art, which will not be repeated here.
[0024] like Figure 1 , Figure 2 and Figure 5 As shown, each spring leaf 3 includes a first connecting portion 31 and two second connecting portions 32 connected to the left and right sides of the first connecting portion 31, each second connecting portion 32 is used to connect a core wire, and a baffle 19 is also provided in the lower cover 1 and is vertically arranged with the partition 4. A gap is left between the front and rear ends of the baffle 19 and the front and rear inner walls of the lower cover 1, and the first connecting portion 31 passes through the gap, and the two second connecting portions 32 are located on the left and right sides of the baffle 19.
[0025] like Figure 1 As shown, one end of each upper cover 2 is rotatably connected to the middle part of the lower cover 1, and the left and right upper covers 2 respectively cover the left half and the right half of the lower cover 1. The lower cover 1 and the two upper covers 2 are provided with fixing components for fixing the lower cover 1 and the upper cover 2. Both ends of the lower cover 1 and / or the other ends of the two upper covers 2 are provided with channels 5 for the passage of the foot line. That is to say, the channel 5 can be provided at both ends of the lower cover 1 alone, or at the other ends of the two upper covers 2 alone, or at both ends of the lower cover 1 and the other ends of the two upper covers 2. In this embodiment, third through grooves 15 are provided at both left and right ends of the lower cover 1, and a fourth through groove 16 is provided at the other end of each upper cover 2. The third through groove 15 and the fourth through groove 16 are both semicircular in shape matching the shape of the foot line. When the upper cover 2 is closed, the third through groove 15 and the fourth through groove 16 are combined to form the channel 5. The left and right channels 5 are coaxially arranged to avoid shear force caused by the non-coaxial arrangement of the two foot lines.
[0026] like Figure 2 and Figure 5 As shown, each second connecting portion 32 includes two interconnected connecting pieces 321, each connecting piece 321 is provided with a first through hole 6 for the core wire to pass through, and a groove is provided at the bottom end of the lower cover 1, and each connecting piece 321 is stuck in the groove; each connecting piece 321 is provided with a first through groove 7 located below the first through hole 6 and connected to the first through hole 6, and each upper cover 2 is provided with a second pressing block 8, and the second pressing block 8 is used to press the core wire into the first through groove 7 when the upper cover 2 is closed.
[0027] In addition, if Figure 1 and Figure 2 As shown, each spring sheet 3 is provided with a guide cylinder 9 on both sides, that is, there are four guide cylinders 9 in total in the lower cover 1, each guide cylinder 9 is provided with a second through hole 10 for the core wire to pass through, and each guide cylinder 9 is provided with a second through groove 11 located below the second through hole 10 and connected to the second through hole 10. Similarly, when the upper cover 2 is closed, the second pressing block 8 presses the core wire into the second through groove 11. In this embodiment, as Figure 3 As shown, two groups of second pressing blocks 8 are arranged on each upper cover 2 along the left-right direction, and each group of second pressing blocks 8 includes two second pressing blocks 8 distributed front and back, and the two second pressing blocks 8 in the same group correspond to two spring sheets 3, wherein one group of second pressing blocks 8 is pressed on the core wire between the two connecting sheets 321, and the other group of second pressing blocks 8 is pressed on the core wire between the guide cylinder 9 and the spring sheet 3.
[0028] The lower cover 1 is provided with two left and right concave surfaces, and each upper cover 2 is provided with a first pressing block 12. When the upper cover 2 is closed, the first pressing block 12 presses on the foot line located in the concave surface and bends the foot line. Figure 3 As shown, the first pressing block 12 is a sawtooth block, which is used to squeeze and pierce the foot line when the upper cover 2 is closed.
[0029] like Figure 1 As shown, two bosses 13 are provided in the lower cover 1 on the left and right sides of the spring sheet 3. Each boss 13 includes a first platform 131, a second platform 132 and a third platform 133 from the outside to the inside of the lower cover 1. The height of the first platform 131 is higher than the third platform 133 to form a concave surface. The upper end surface of the second platform 132 is an inclined surface, which serves as a transition between the first platform 131 and the third platform 133. The position of the first pressing block 12 corresponds to the third platform 133, that is, when the upper cover 2 is closed, the first pressing block 12 presses on the foot line on the third platform 133, so that the foot line forms a Z-shaped structure to increase the pulling force; in this embodiment, the first platform 131 is directly set inward from the end of the lower cover 1, so that the third through groove 15 also extends to the first platform 131. In addition, a limiting groove 14 is provided on the upper end surface of each third platform 133.
[0030] Use wire strippers to cut off the leg wire that needs to be extended, and use wire strippers to strip off the outer sheath of the leg wire end that needs to be bridged, exposing the two core wires in the leg wire, one of which passes through the second through hole 10 of one of the guide cylinders 9 and the first through hole 6 of the two connecting pieces 321 of one of the spring leaves 3 in turn, and the other core wire passes through the second through hole 10 of the other guide cylinder 9 and the first through hole 6 of the two connecting pieces 321 of the other spring leaf 3 in turn. The leg wire is located on the boss 13, and the other leg wire that needs to be bridged is connected to the other side in the same way. The two core wires of one leg wire pass through the spring leaf 3 and The two core wires of the other leg wire are connected correspondingly, and then the two upper covers 2 are closed to complete the leg wire bridging and realize the leg wire connectivity. The leg wire will not be wasted and the progress of the project will not be affected by replacing the leg wire due to insufficient length. The connection problem between leg wires of different materials used in the on-site wiring process due to different on-site terrain, environment, temperature, specifications and other factors is solved. Each second pressing block 8 and the first pressing block 12 are pressed on the corresponding core wire and leg wire, and the first pressing block 12 pierces the leg wire and makes the leg wire form a Z-shaped structure to increase the pulling force, which can reach a pulling force of 45 kg.
[0031] The fixing components are four buckle components 17 provided on the lower cover 1 and the two upper covers 2. Each upper cover 2 is fixed to the lower cover 1 by two buckle components 17 symmetrically provided front and back. Figure 4 As shown, the buckle assembly 17 includes a protrusion 171 provided on the inner wall of the upper cover 2 and a block 172 provided on the lower cover 1. The block 172 is provided with a slot 18 for the protrusion 171 to be inserted into. The upper end surface of the block 172 is provided with a guiding slope. When the upper cover 2 is closed, the lower end of the protrusion 171 abuts against the guiding slope to deform the block 172. As the upper cover 2 rotates, the protrusion 171 is inserted into the slot 18.
