Technical Field

The problem that the fixed socket lacks flexibility is solved in the emergence of track socket distribution system, in order to solve the problem of alternating current and direct current conversion in the domestic power consumption, need set up the conversion module that is used for converting alternating current in track socket distribution system.

As shown in fig. 3, 8 and 10, in some embodiments, the receptacle housing 10 further includes a second mounting slot 14 and an insulating sleeve 15; the second mounting groove 14 is disposed on the inner wall of the socket housing 10 and is opened along the length direction of the socket housing 10, for placing the first conductive component 20 and the second conductive component 30; the insulating sleeve 15 is wrapped around the first conductive component 20 and the second conductive component 30, and the length of the insulating sleeve 15 is longer than the length of the first conductive component 20 and the length of the second conductive component 30, so as to isolate the first conductive component 20 from the socket housing 10 and isolate the second conductive component 30 from the socket housing 10; an isolation structure 151 is provided on the inner wall of the insulating sleeve 15 for isolating the first conductive member 20 from the second conductive member 30.

Aluminum is light in weight, low in cost, and has a high strength to weight ratio, and the socket housing 10 is made of aluminum material, so that the structural strength can be ensured while maintaining a low production cost. The brass has superior conductivity, and the first conductive component 20 and the second conductive component 30 are made of brass, and because the first conductive component 20 and the second conductive component 30 are all provided with current, and the aluminum socket housing 10 is also provided with conductivity, a user can touch the socket housing 10 frequently in the use process, so that the first conductive component 20 and the second conductive component 30 are required to be isolated from the socket housing 10, and the electric shock danger is avoided.

Therefore, the second mounting groove 14 is provided in the socket housing 10, so that the first conductive member 20 and the second conductive member 30 are both mounted in the second mounting groove 14, and the insulating sleeve 15 provided in the second mounting groove 14 is wrapped around the first conductive member 20 and the second conductive member 30, so that the first conductive member 20 and the second conductive member 30 are both spaced apart from the socket housing 10, thereby preventing the user from electric shock.

Further, since the current transmitted in the first conductive element 20 is 220V ac and the current transmitted in the second conductive element 30 is 24V dc, the first conductive element 20 and the second conductive element cannot communicate with each other, and isolation is also required.

An isolation structure 151 is provided on the inner wall of the insulating sleeve 15 for isolating the first conductive member 20 from the second conductive member 30 to prevent a short circuit.

In a second aspect, as shown in fig. 1, the present application provides a power distribution system 100 for a track jack, comprising: the track jack 1 and adapter of any of the above embodiments; the adapter is clamped in a clamping gap 11 at the top of the socket housing 10, so that the adapter is electrically connected with the track socket 1.

As shown in fig. 1, in some embodiments, the adapters include an ac adapter 2 and a dc adapter 3; the alternating current adapter 2 is electrically connected with the first conductive component 20; the dc adapter 3 is electrically connected to the second conductive member 30.

By the embodiment, the alternating current adapter 2 is clamped on the track socket 1 through the clamping seam 11 and is electrically connected with the first conductive component 20, so that the alternating current in the first conductive component 20 flows into the alternating current adapter 2; the direct current adapter 3 is clamped on the track socket 1 through the clamping gap 11 and is electrically connected with the second conductive component 30, so that direct current in the second conductive component 30 flows into the direct current adapter 3.

Specifically, two pins for being clamped in the clamping gaps 11 are arranged on the alternating current adapter 2 and the direct current adapter 3, wherein the two pins on the alternating current adapter 2 are respectively connected to the L-pole conductive piece 21 and the N-pole conductive piece 22; two pins on the direct current adapter 3 are respectively connected to two conductive copper bars.

Different pin pitches can be arranged to realize that the alternating current adapter 2 can be connected with the first conductive component 20 when being clamped on the track socket 1, and the direct current adapter 3 can be connected with the second conductive component 30 when being clamped on the track socket 1.

For example, the distance between the L-pole conductive piece 21 and the N-pole conductive piece 22 is a, and the distance between the two conductive copper bars is b; then, the adapter having the pitch of a set between the two pins is the ac adapter 2, and the adapter having the pitch of b set between the two pins is the dc adapter 3.

As can be seen, compared with the prior art, the dc adapter 3 needs to be provided with a conversion module for ac and a separator for preventing EMC interference; the difference between the direct current adapter 3 and the alternating current adapter 2 in the embodiment of the application is only the difference of the pin distances, so that the assembly difficulty and the production cost of the direct current adapter 3 are greatly reduced.
