[0032] In order to make the utility model purposes, features, advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiment, and the technical scheme in the utility model embodiment is clearly and completely described, obviously, the following described embodiments are only a part of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the scope of the utility model.

[0033] Please refer to Figures 1 to 3 The utility model provides a light splitter with wireless power supply function, which comprises:

[0034] Base 1, rotating table 2 installed on base 1 in the way of self-rotation, light splitter 3 and intelligent device 4 arranged on rotating table 2, at least one pair of signal transmitting member 5 and signal receiving member 6 used in pairs, signal transmitting member 5 and signal receiving member 6 face each other;

[0035] Signal transmitting member 5 is arranged on base 1, and signal transmitting member 5 is used for electrically connecting with external power supply 8;

[0036] One or more of rotating table 2, light splitter 3 and intelligent device 4 are provided with signal receiving member 6, and signal receiving member 6 is electrically connected with intelligent device 4 and / or light splitter 3;

[0037] Among them, each team signal receiving member 6 is connected with signal transmitting member 5 in the way of electromagnetic coupling, and the material of the structure between signal transmitting member 5 and signal receiving member 6 is non-electromagnetic shielding material.

[0038] In the working process of the embodiment, the signal emitter 5 is electrically connected with the external power supply 8 through the power line, the external power supply 8 transmits current to the signal emitter 5 located in the base 1, the signal emitter 5 generates an induced magnetic field, the signal receiver 6 generates an induced current in the induced magnetic field, and transmits the current to the signal receiver 6 on the rotating table 2 in the form of an electromagnetic signal, and the signal receiver 6 converts the electromagnetic signal into current again and transmits the current to the intelligent device 4 and / or the optical splitter 3 through the power line, so that the intelligent device 4 and the optical splitter 3 on the rotating table 2 can rotate normally.

[0039] As can be seen from the above working process, the user can continuously rotate the rotating table according to the test requirements, and the signal receiver 6 can still receive the electromagnetic signal of the signal emitter 5 during rotation, generate stable current, and supply power to the intelligent device 4 and the optical splitter 3.

[0040] Compared with the prior art, the present scheme has the advantage that the wireless power supply mode replaces the traditional power line direct power supply mode, that is, the signal emitter 5 of the base 1 is electrically connected with the external power supply 8, the signal emitter 5 of the base 1 is wirelessly connected with the signal receiver 6 of the rotating table 2, and the signal receiver 6 is electrically connected with the intelligent device 4 and the optical splitter 3, which replaces the direct connection mode of the intelligent device 4 and the optical splitter 3 with the external power supply 8 through the power line. The rotating table 2 and the base 1 are no longer connected by the power line, and even if the rotating table 2 is arbitrarily rotated, the power line directly connected with the external power supply 8 will not be entangled, which effectively reduces the interference of the power line on the test.

[0041] In a specific embodiment, the number of signal emitters 5 and signal receivers 6 can be one pair, two pairs or three pairs or even more, that is, a plurality of signal emitters 5 can be arranged on the rotating table 2, and a number of signal receivers 6 matched with the number of signal emitters 5 are arranged on one or more of the rotating table 2, the optical splitter 3 and the intelligent device 4, so as to realize wireless power consumption of the structure on the rotating table.

[0043] In a specific embodiment, as shown in Figure 3 The transmitting coil 50 and the receiving coil 60 are hollow ring structures with a thickness of generally 2 mm; and the transmitting circuit 51 and the receiving circuit 61 are arranged on circuit boards respectively.

[0048] Based on the above embodiment, in order to further improve the transmission effect of the receiving coil 60 and the transmitting coil 50, as shown in Figure 1 and Figure 2 , a preset gap is left between the transmitting coil 50 and the receiving coil 60, and the user can set the preset gap within a reasonable range, so that the position of the receiving coil 60 is the optimal electromagnetic signal position of the transmitting coil 50, thereby improving the transmission effect of the receiving coil 60 and the transmitting coil 50.

[0049] In this embodiment, as shown in Figure 1 and Figure 2 , the preset gap is 10 mm. Of course, considering the installation error, the preset gap can be 5 mm, 15 mm, or any value within the range of 5-15 mm.

The first tray 70 is fixedly connected with the base 1, and the first tray 70 is annularly arranged around the rotating shaft 20 of the rotating table 2. The first plug-in disc 71 is inserted into the first tray 70, and the transmitting coil 50 is pressed between the first plug-in disc 71 and the first tray 70.

The second plug-in disc 73 is inserted into the second tray 72, and the receiving coil 60 is pressed between the second plug-in disc 73 and the second tray 72. The gap between the transmitting coil 50 and the receiving coil 60 is kept within the preset gap by the cooperation of the first tray 70, the first plug-in disc 71, the second tray 72, and the second plug-in disc 73. When the transmitting coil 50 needs to be disassembled, the first plug-in disc 71 can be inserted into or pulled out of the first tray 70, so that the transmitting coil 50 is put into or moved out of the first tray 70, and then the first plug-in disc 71 is inserted into the first tray 70. The disassembly of the receiving coil 60 is similar, and the second plug-in disc 73 can be moved to complete the disassembly. Therefore, no more description is given here.

[0051] The first tray 70 is fixed to the base 1 by bonding, screwing or the like, and the second tray 72 is fixed to the rotating table 2 by bonding, screwing or the like.

[0052] In this embodiment, the material of the first plug-in tray 71 and the second plug-in tray 73 is one of plastic, paper, wood, and ceramics. The first plug-in tray 71 and the second plug-in tray 73 are structures between the signal transmitter 5 and the signal receiver 6. The structure cannot have a metal structure. These structures are structures formed by non-electromagnetic interference materials. Plastic, paper, wood, and ceramics are all non-electromagnetic interference materials.

[0055] After using the magnetic resonance wireless power supply module, its transmission distance can be longer than that of the electromagnetic induction type, and to a certain extent, the requirements for the position of the transmitter and receiver are relatively loose, which can achieve wireless power supply of medium distance and power.
