Technical Field
[0001] This utility model relates to the field of tunnel lighting power distribution, specifically a prefabricated flexible busbar power distribution system with tunnel guidance markers and socket outputs. Background Technology
[0002] In existing technologies, the branch wiring of tunnel guide beacon cables is mostly done manually by stripping and twisting the insulation, followed by wrapping with insulating tape. This method is not only time-consuming to install, but also cannot guarantee good connection quality and waterproofing requirements. Because the main power supply line for tunnel guide beacons is a two-core cable with single-strand hard wire conductors, while the power supply line conductors are multi-strand thin copper wires, the connection can only be done by wrapping the multi-strand thin copper wires around the stripped single-strand hard wire. Without tinning, the joint is prone to loosening, leading to poor wiring and oxidation. Furthermore, the insulating tape wrapping cannot truly waterproof and moisture-proof the cable, and there is a risk of aging. In addition, this installation method is cumbersome, requires the fabrication of two branch joints, and results in a messy appearance. Summary of the Invention
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a tunnel induced sign with a socket output prefabricated flexible busbar power distribution system.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: 1. A prefabricated flexible busbar power distribution system with tunnel guide beacon and socket output, comprising a two-core trunk cable and several prefabricated socket output molded branch joints at certain intervals and several guide beacons; The aforementioned socket output molded branch connector is formed by connecting the socket wiring assembly to the trunk cable, forming a branch connector, and then molding it to create a molded branch connector. The socket wiring assembly includes a circuit board, a two-core socket core, and two solder pads; The two-core socket core has a positive pin and a negative pin. The positive pin and the negative pin are inserted into the positive pin metallization hole and the negative pin metallization hole from the front of the circuit board, and are respectively soldered to the positive copper foil and the negative copper foil on the back of the circuit board. The two solder pads are inserted into the positive and negative metallization holes of the solder pads from the back of the circuit board, respectively, and are soldered to the positive and negative copper foils on the front of the circuit board. The positive electrode of the pin is electrically connected to the positive electrode of the solder pad through the positive electrode copper foil, the positive electrode metallization hole of the pin, the positive electrode metallization hole of the solder pad, and their respective solder joints; The negative electrode of the pin is electrically connected to the negative electrode of the solder pad through the negative electrode copper foil, the negative electrode metallization hole of the pin, the negative electrode metallization hole of the solder pad, and their respective solder joints. The two solder tab openings on the socket wiring assembly are respectively soldered to the positive and negative terminals of the main conductor of the two-core trunk cable; The guide beacon outputs a two-core cable whose end conductors are respectively soldered to the positive and negative terminals of the two-core plug core. Then, a two-core plug is molded for insertion into the two-core socket on the molded branch connector.
[0005] 2. The two-core socket core is provided with a positioning protrusion, and the two-core plug core is provided with a positioning notch. The two work together to ensure correct wiring and prevent incorrect insertion.
[0006] 3. The front of the circuit board is marked with socket markings to ensure the correct installation of the two-pin socket core on the circuit board; The positive marking is printed on the positive copper foil on the back of the circuit board, and the negative marking is printed on the negative copper foil. The purpose is to indicate the correct connection when the socket connection assembly is connected to the two-core trunk cable.

[0031] The embodiments of this utility model are described below with reference to the accompanying drawings.
[0032] Figure 1 and Figure 2 The circuit board 1 of this utility model is described.
[0033] On the front side 1A and the back side 1B of the circuit board, Both are provided with positive copper foil 1Z, which are identical in shape, and together they form an integral positive electrode through the positive electrode metallization hole 1Z1 of the insert pin and the positive electrode metallization hole 1Z2 of the solder sheet; Both are equipped with negative copper foil 1F, which are identical in shape. They form an integral negative electrode through the negative electrode metallization hole 1F1 of the insert and the negative electrode metallization hole 1F2 of the solder sheet. On the front side 1A of the circuit board, a socket mark 12 is printed to ensure that the two-core socket core 2 is correctly installed on the circuit board 1; on the back side 1B of the circuit board, a positive mark 13Z is printed on the positive copper foil 1Z and a negative mark 13F is printed on the negative copper foil 1F to indicate the correct connection when the socket connection assembly 1ZJ is connected to the two-core trunk cable 4.
[0034] Figure 3 The present invention shows a two-core socket core 2, which is provided with a positioning protrusion 21, and also provides a positive pin 2Z and a negative pin 2F.
[0035] Figure 4 The present invention shows a solder pad 3, which has solder pad feet 31 for soldering to a circuit board 1; and a solder pad opening 32 for soldering the positive electrode 4Z or the negative electrode 4F of the trunk conductor of a two-core trunk cable 4.
[0036] Figures 5-8 The structure and assembly of the socket wiring assembly 1ZJ of this utility model are described.
[0037] Step 1: Install the two-pin socket pin 2 on circuit board 1: From the front side 1A of the circuit board, insert the positive pin 2Z and the negative pin 2F of the two-pin socket core 2 into the positive pin metallization hole 1Z1 and the negative pin metallization hole 1F1, and then solder them to the positive copper foil 1Z and the negative copper foil 1F on the back side 1B of the circuit board, respectively, to form two independent pin solder joints 14.
[0038] The second step is to install solder pad 3 on circuit board 1: From the reverse side 1B of the circuit board, insert the solder pads 31 of the two solder pads 3 into the positive electrode metallization holes 1Z2 and the negative electrode metallization holes 1F2 of the solder pads, respectively, and then solder them to the positive electrode copper foil 1Z and the negative electrode copper foil 1F on the front side 1A of the circuit board, respectively, to form two independent solder pad solder joints 15.
[0039] The assembly of the socket wiring assembly 1ZJ is completed through the above two steps. At this point, The positive electrode 2Z of the pin is electrically connected to the positive electrode 3 through the positive electrode copper foil 1Z, the positive electrode metallization hole 1Z1 of the pin, the positive electrode metallization hole 1Z2 of the solder pad, and their respective solder joints. The negative electrode 2F of the pin is electrically connected to the solder pad 3, which serves as the negative electrode, through the negative electrode copper foil 1F, the negative electrode metallization hole 1F1 of the pin, the negative electrode metallization hole 1F2 of the solder pad, and their respective solder joints.
[0040] The following is through Figures 9-11 and combined Figure 18 Explain the composition and structure of the two-core plug core and the guiding target.
[0041] The two-core plug core 61 has a positioning notch 611, and also has a positive terminal 61Z and a negative terminal 61F. The positive conductor 62Z and negative conductor 62F of the two-core cable 62 are soldered to the positive terminal 61Z and negative terminal 61F of the socket, respectively, forming two independent socket solder joints 63. Then, the two-core plug 61T is molded. The other end of the two-core cable 62 is connected to the light-emitting diode group 64 of the guide beacon 6.
[0042] Figures 12-16 The assembly process and structure of the branch connector 51 and the molded branch connector 5 of this utility model are described, and the following steps are included: Step 1: Strip the sheath and conductor insulation from the two-core trunk cable 4 to expose the positive terminal 4Z and negative terminal 4F of the trunk conductor; Step 2: Insert the two solder tab openings 32 of the socket wiring assembly 1ZJ into the positive terminal 4Z and negative terminal 4F of the main conductor according to the positive terminal mark 13Z and negative terminal mark 13F on the reverse side 1B of the circuit board, and solder them to form two independent solder tab solder joints 16, thus making the branch connector 51. This connects the positive terminal 4Z of the main conductor to the positive terminal 2Z of the pin in the two-core socket 2, and connects the negative terminal 4F of the main conductor to the negative terminal 2F of the pin in the two-core socket 2. Step 3: Mold the branch connector 51 to make a molded branch connector 5 with a socket output mode.
[0043] from Figure 16 As can be seen, after molding, the molding compound 52 fills all the gaps in the branch joint 51, achieving the purpose of waterproofing and preventing condensation.
[0044] Figure 17 The general embodiment of this utility model is shown.
[0045] First, on the two-core trunk cable 4, make the molded branch connector 5 according to steps 1-3 above; Next, repeat steps 1-3 at 10-meter intervals or the required intervals to fabricate several molded branch connectors 5 for the output sockets, thus completing the prefabricated flexible busbar for the tunnel guide strip sockets. To protect the exposed output sockets, socket protective caps 22 are also installed on the sockets to avoid damage during packaging, transportation, and installation.
[0046] This busbar, together with several 61T input guide markers with two-core plugs, constitutes the present invention a prefabricated flexible busbar power distribution system with socket output for tunnel guide markers.
[0047] During on-site installation, after the prefabricated flexible busbar output from the tunnel guide marker socket is laid in place on the cable trench support, holes are drilled in the side wall of the cable trench according to the corresponding position of the molded branch joint 5, and the two-core plug 61T and two-core cable 62 are passed through and the guide marker is fixed in place. Then, the two-core plug 61T is inserted into the two-core socket core 2 in the cable trench, thus completing the installation of a single guide marker 6.
[0048] Because a positioning protrusion 21 is provided on the two-core socket core 2 and a positioning notch 611 is provided on the two-core plug core 61, the two work together to ensure correct wiring and prevent incorrect insertion.
[0049] Figure 18 The connection principle of this utility model is described.
[0050] As shown in the diagram, the negative electrode electrical connection path is formed by the following connections: conductor negative electrode 4F → solder pad opening 32 → solder pad opening solder joint 16 → solder pad 3 → solder pad negative electrode metallized hole 1F2 → solder pad lead 31 → solder pad lead solder joint 15 → negative electrode copper foil 1F → pin negative electrode metallized hole 1F1 → pin solder joint 14 → pin negative electrode 2F → socket negative electrode 61F → conductor negative electrode 62F → LED group 64 negative electrode.
[0051] Similarly, the positive electrode electrical connection path is formed by the following connections: positive electrode 4Z of the main conductor → solder pad opening 32 → solder pad opening solder joint 16 → solder pad 3 → solder pad positive electrode metallization hole 1Z2 → solder pad lead 31 → solder pad lead solder joint 15 → positive electrode copper foil 1Z → pin positive electrode metallization hole 1Z1 → pin solder joint 14 → pin positive electrode 2Z → socket positive electrode 61Z → conductor positive electrode 62Z → light-emitting diode group 64 positive electrode.
[0052] In this way, the DC power obtained from the two-core trunk cable 4 is transmitted to the guide beacon 6 and lit up.
