Description

Technical Field

[0001] This utility model relates to photovoltaic cables, and more particularly to a one-to-two cable. Background Technology

[0002] In current solar modules, to improve power generation efficiency, a micro inverter is installed on each solar panel to convert direct current to alternating current. Then, multiple micro inverters are connected to the same inverter for transmission using electrical connections.

[0003] Existing microinverter connections are one-to-one. Specifically, each microinverter has a male and a female connector, which are connected to the female and male connectors of the inverter using two solar wiring harnesses, respectively. However, this method leads to complex wiring and requires multiple female and male connectors on the inverter, limiting the number of microinverters that a single inverter can connect to, and also results in higher costs. Utility Model Content

[0004] The main purpose of this invention is to propose a photovoltaic one-to-two cable, which solves the problem that the existing one-to-one connection between micro-inverters leads to complex wiring.

[0005] To achieve the above objectives, the present invention proposes a photovoltaic one-to-two cable, which has the following characteristics:

[0006] A first cable, which has:

[0007] A first connector is disposed at one end of the first cable;

[0008] Two second cables are electrically connected to the first cable, and each second cable has:

[0009] A second connector is disposed at the end of the second cable away from the first cable;

[0010] A housing is disposed at and covers the junction of the first cable and the second cable;

[0011] A filler is disposed inside the housing and covers the junction of the first cable and the second cable to fix the first cable and the second cable.

[0012] As mentioned earlier, in a photovoltaic one-to-two cable, where,

[0013] The first cable has:

[0014] The first wire sheath;

[0015] A first wire bundle, which is disposed within the outer sheath of the first wire;

[0016] Each of the second cables has

[0017] A second outer sheath of the wire;

[0018] A second wire bundle, which is disposed within the outer sheath of the second wire;

[0019] The photovoltaic one-to-two cable has a metal buckle disposed inside the housing. The first wire bundle and each of the second wire bundles pass through the metal buckle and are electrically connected in the metal buckle.

[0020] As described above, the photovoltaic one-to-two cable also has an outer shell layer that covers the housing.

[0021] As described above, the photovoltaic one-to-two cable, wherein the housing also has:

[0022] A first plastic shell, which has:

[0023] Multiple engaging grooves are formed on the side of the first housing;

[0024] A second plastic shell, which has:

[0025] Multiple engaging components are provided, each of which is disposed on the side of the second housing and can engage in one of the engaging slots.

[0026] As described above, the photovoltaic one-to-two cable also has a glue injection hole that passes through the first glue shell or the second glue shell.

[0027] As described above, the photovoltaic one-to-two cable also has a glue injection hole that penetrates one side of the housing.

[0028] In use, this invention requires first connecting the second connectors of each of the second cables to the micro-inverter in the solar module, and then connecting the first connector of the first cable to the inverter in the solar module. Therefore, the micro-inverter connectors and inverter connectors form a two-to-one connection. The advantage of this invention is that by changing the connection between the micro-inverter connectors to a two-to-one connection, the number of connecting cables required between the micro-inverter and the inverter is reduced, thereby reducing costs. Furthermore, this invention uses filler material injected into the housing at the junction of the first cable and the two second cables, thereby improving the waterproof and insulating properties of the invention.

[0034] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.

[0035] Please refer to Figure 1 and Figure 5 This utility model proposes a photovoltaic one-to-two cable. In this embodiment, the utility model has a first cable 10, two second cables 20, a metal buckle 30, a housing 40, a filler 50, and an outer shell layer 60. In other embodiments, the utility model may not have the metal buckle 30 and the outer shell layer 60.

[0036] Please refer to Figure 1 and Figure 2 The first cable 10 has a first wire sheath 11, a first wire harness 12, and a first connector 13. The first wire sheath 11 covers the first wire harness 12, and the first wire harness 12 protrudes from one end of the first wire sheath 11. The first connector 13 is disposed at one end of the first cable 10. Each second cable 20 has a second wire sheath 21, a second wire harness 22, and a second connector 23. The second wire sheath 21 covers the second wire harness 22, and the second wire harness 22 protrudes from one end of the second wire sheath 21. The second connector 23 is disposed at the end of the second cable 20 away from the first cable 10. A metal clip 30 connects the first cable 10 and the two second cables 20. Specifically, the portion of the first wire harness 12 protruding from the first wire sheath 11 and the portion of each second wire harness 22 protruding from the second wire sheath 21 pass through the metal clip 30 and are electrically connected in the metal clip 30.

[0037] Please refer to Figures 2 to 4A housing 40 is disposed and covers the junction of the first cable 10 and the two second cables 20, and has a first housing 41, a second housing 42, and an injection hole 43. The first housing 41 has a plurality of engaging grooves 411, and each engaging groove 411 is formed on the side of the first housing 41. The second housing 42 has a plurality of engaging members 421. Each engaging member 421 is disposed on the side of the second housing 42 and can engage in one of the engaging grooves 411. In this embodiment, each engaging member 421 protrudes toward the first housing 41 and has a protrusion 4211, which can be disposed in the corresponding engaging groove 411. In other embodiments, the joining method of the first housing 41 and the second housing 42 is not limited to this, and can also be joined by adhesive bonding. In this embodiment, there are four engaging members 421 and four engaging slots 411. In other embodiments, the number of engaging members 421 and four engaging slots 411 is not limited to this. The glue injection hole 43 can penetrate one side of the housing 40. In this embodiment, the glue injection hole 43 penetrates the first housing 40. In other embodiments, the glue injection hole 43 can also penetrate the second housing 40.

[0038] Please refer to Figure 5 The filler 50 is disposed within the housing 40 and covers the junction of the first cable 10 and the second cable 20 to secure the first cable 10 and the second cable 20. Specifically, the filler 50 can be injected into the housing 40 through the injection hole 43, and in this embodiment, the filler 50 is polyurethane sealant, which makes the first cable 10 and the second cable 20 more waterproof and insulating. The outer shell layer 60 can cover the housing 40, and the filler 50 can be sealed within the outer shell layer 60.

[0039] In use, this invention requires first connecting the second connector 23 of each second cable 20 to the micro-inverter in the solar module, and then connecting the first connector 13 of the first cable 10 to the inverter in the solar module. Therefore, the connectors of the micro-inverter and the inverter are connected in a two-to-one configuration.

[0040] The advantage of this invention lies in changing the connection between the micro-inverter and the inverter to a two-to-one connection, thereby reducing the number of connecting cables required between the micro-inverter and the inverter, and thus reducing costs. In addition, at the junction of the first cable 10 and the two second cables 20, a filler 50 is used to fill the housing 40, thereby improving the waterproof and insulation capabilities of this invention.
