[0025] To make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described in this application are only part of the embodiments of the present utility model, rather than all embodiments. Based on the spirit of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0026] As Figures 1-4 shown, Embodiment 1 of the present utility model provides an arc-proof socket, including the body 1 of the arc-proof socket, a visual digital ammeter 2, a DC socket housing 3, a connection base, a DC circuit breaker 7, a positive and negative line wiring 9, and a main switch button 12.

[0027] The body 1 of the arc-proof socket and the DC socket housing 3 form a receiving box structure, the upper surface of which is a DC socket panel, provided with a window, and the area of the window is the same as that of the visual digital ammeter 2, and the visual digital ammeter 2 is arranged below the window;

[0028] In a preferred but non-limiting implementation manner of the present utility model, the upper surface of the DC socket housing 3 is detachable and is fixed to the DC socket housing 3 through a fastening screw 6.

[0029] The electrical connection bases are arranged side by side inside the DC socket housing 3, and their quantity can be set according to specific usage conditions. The electrical connection base includes an elastic conductive seat piece 4, an insulation resistance 5, a fastening card 10, and an anti-conductive plate 11. The fastening card 10 is arranged on the anti-conductive plate 11, the insulation resistance 5 is arranged on the elastic conductive seat piece 4, and the elastic conductive seat piece 4 is connected to the fastening card 10 to form the electrical connection base.

[0030] The plug conductive holes of this DC visual pull-arc socket are designed as vertical and horizontal holes to prevent the positive and negative poles of the socket from being inserted reversely; at the same time, the plug has a current digital visualization function and a current plug alarm function to cut off the current circuit in a timely manner.

[0031] It should be noted that the arc-proof function of the socket described in this application is that the conductive column of the electrical plug and the positive and negative line wiring, that is, the copper contact row in the arc-proof socket. When separated, especially at the moment when the conductive column breaks away, the conductive sheets on both sides of the insulation resistance 5 abut against the elastic conductive seat piece 4, so that the resistance in the on-off circuit of the powered device increases instantaneously, and the voltage rises. At this time, the arc is instantaneously extinguished under the influence of the voltage drop, avoiding the problem that a DC arc will occur when the conductive column is separated from the elastic conductive seat piece 4.

[0032] Further preferably, the electrical connection base is connected to the visual digital ammeter 2 through the positive and negative line wiring 9.

[0033] The DC circuit breaker 7 is connected to the visual digital ammeter 2, and the main switch button 12 is arranged on the upper part of the DC socket housing 3 to control the switch of the current visual DC arc-proof socket.

[0034] The visual digital ammeter 2 can read the current and mark the maximum current passing value to realize the early warning of the over-current value.

[0035] In a preferred but non-limiting embodiment of the present utility model, the electrical connection base may also be provided with a USB charging socket 8. The USB interface 8 reduces the voltage to the voltage required for ordinary mobile phone charging through a DC-DC buck circuit to ensure charging safety. Because it is a DC-connected socket itself, the energy loss in the AC-DC conversion process is eliminated, maximizing the energy utilization.

[0036] The working process of a current visual DC arc-proof socket described in this application is as follows:

[0037] When the DC socket is powered on, the visual ammeter can display the rated current of this DC socket and the current passing through this DC socket. When the passing current exceeds 95% of the rated current, the ammeter dial emits a red light, indicating that this socket is about to be overloaded. The release of the circuit breaker in the DC quick circuit breaker 7 inside the socket starts to operate. The operation of the release causes the quick transmission mechanism to release, and the contacts start to separate to protect the safety of the electrical equipment.

[0038] The beneficial effect of the present utility model is that, compared with the prior art,

[0039] The present utility model provides a DC arc-proof socket with current visualization. By setting a visual digital ammeter, the reading of the passing current value can be realized to achieve overload warning. At the same time, the electrical socket is provided with an insulation resistance, which can effectively realize the safety protection of the DC arc-proof socket. And when the current exceeds the rated current, the arc-proof socket will trip through the DC circuit breaker to protect the safety of the electrical equipment.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them.
