Example one

As shown in fig. 1, an anti-plug sparking power assembly provided by the embodiment of the present invention includes a plug 100, wherein the plug 100 is configured to be matched with a socket 200; the plug 100 includes: a first wire piece 110, a second wire piece 120, and a resistive load 130; the resistive load 130 is provided on the first wire member 110, and the first wire member 110 is configured to be connected to the socket 200 prior to the second wire member 120.

Specifically, the first wire member 110 and the second wire member 120 are used to connect the positive terminal or the negative terminal of the power supply device 500, and the first wire member 110 can be connected to the socket 200 prior to the second wire member 120. When the plug 100 is initially connected with the socket 200, the first wiring piece 110 is connected with the socket 200, and a closed path is formed, the resistive load 130 is connected in series in the circuit, so that excessive current can be prevented from being generated in the path, and electric sparks caused by excessive current can be prevented from being generated at the moment that the plug 100 is connected with the socket 200. When the second wire connecting piece 120 connects the socket 200, the resistance value of the second wire connecting piece 120 is smaller than the sum of the resistances of the first wire connecting piece 110 and the resistive load 130, and the second wire connecting piece 120 can short-circuit the first wire connecting piece 110 and the resistive load 130, so that the voltage division of the resistive load 130 can be avoided, and the power supply device 500 can normally supply power.

It should be noted that, if the first connection element 110 and the second connection element 120 are connected to the positive terminal and the negative terminal of the power supply device 500 in a one-to-one correspondence manner, the resistive load 130 is used to avoid the current from being too large at the moment of circuit connection, and to prevent the circuit from generating an arc due to the rapid charging of the capacitive device, so as to achieve the purpose of preventing the electric spark. However, in order to avoid voltage division of the resistive load 130 and ensure that the power supply device 500 can normally supply power, it is preferable to connect both the first wiring member 110 and the second wiring member 120 to the positive terminal or the negative terminal of the power supply device 500 and to enable the second wiring member 120 to short-circuit the resistive load 130 in a state of being connected to the socket 200. When the socket is powered on, the first wiring piece 110 is connected to the socket 200 before the second wiring piece 120, and the time difference between the first wiring piece 110 and the second wiring piece 120 being respectively connected to the socket 200 should be less than 1 second, so that the resistive load 130 is prevented from consuming electric energy or being damaged due to long-time power-on.

When the plug 100 is connected to the socket 200, the first wiring piece 110 is firstly connected with the socket 200, so that the resistive load 130 is connected in series in a passage, and the electric spark caused by overlarge current at the moment of connecting a circuit can be avoided. When the plug 100 is connected, the second wire connecting piece 120 can be connected in parallel with the first wire connecting piece 110, and when the second wire connecting piece 120 is connected with the socket 200, the second wire connecting piece 120 short-circuits the first wire connecting piece 110 and the resistive load 130, so that the resistive load 130 is prevented from continuously dividing voltage in a circuit, and the electric energy loss is reduced.

Further, the resistive load 130 has a resistance value of 3 to 50 ohms. The resistance value of the resistive load 130 may be 4 ohms, 5 ohms, 10 ohms, 15 ohms, 20 ohms, 25 ohms, 30 ohms, 35 ohms or 45 ohms, the resistance value of the resistive load 130 may be selected according to the power supply voltage, and when the power supply voltage is higher, the resistance value of the resistive load 130 is correspondingly increased, so as to avoid an excessive current at the moment of circuit connection. In addition, a plurality of resistive loads 130 arranged in parallel can be adopted to improve the current capacity of the circuit.

Further, the plug 100 further includes a third wire member 140, the third wire member 140 being configured to be connected to the socket 200 prior to the second wire member 120; the third wire member 140 is used to connect one of the positive and negative terminals of the power supply device 500, and the other of the positive and negative terminals connects the first wire member 110 and the second wire member 120.

Specifically, the first wiring element 110 and the third wiring element 140 are connected to the socket 200 before the second wiring element 120, the power supply device 500, the resistive load 130, the first wiring element 110, the power receiving device 600 and the third wiring element 140 jointly form a loop, and the current in the loop is limited by the resistive load 130, so that electric sparks generated at the moment when the plug 100 is connected with the socket 200 are avoided. In the state that the plug 100 is completely jointed with the socket 200, the second wiring piece 120 is connected with the socket 200, the second wiring piece 120 short-circuits the first wiring piece 110 and the resistive load 130, and the power supply device 500, the second wiring piece 120, the power receiving device 600 and the third wiring piece 140 jointly form a loop, the power supply device 500 can directly supply power to the power receiving device 600, and the partial voltage and the electric energy loss generated by the current through the resistive load 130 are avoided.

Further, the plug-in ignition prevention power-on assembly further comprises a socket 200; the socket 200 includes: a first contact set 210 and a second contact set 220, the receptacle 200 being configured to connect a capacitive load 300 between the first contact set 210 and the second contact set 220; the first contact group 210 is fitted to the first wire member 110 and the second wire member 120, and the first wire member 110 abuts the first contact group 210 before the second wire member 120.

When the plug 100 is initially connected to the socket 200, the first wiring member 110 is connected to the first contact group 210, and the third wiring member 140 is connected to the second contact group 220; when the plug 100 is further mated with the receptacle 200 until the second wiring member 120 is connected with the first contact set 210, the second wiring member 120 and the first contact set 210 together short the resistive load 130, so that the power supply device 500, the second wiring member 120, the first contact set 210, the power receiving device 600, the second contact set 220, and the third wiring member 140 together form a loop.

As shown in fig. 3 and 4, the plug-in and sparking prevention power-on assembly further includes a pushing mechanism 400, wherein the pushing mechanism 400 is connected with the plug 100 or the socket 200, and causes the plug 100 and the socket 200 to have a tendency to abut against each other in a state that the plug 100 is mated with the socket 200.

In some embodiments, the pushing mechanism 400 may employ a telescoping device such as a hydraulic cylinder, which drives the plug 100 and receptacle 200 against each other to ensure a tight engagement.

It should be noted that, under the condition that the pushing mechanism 400 makes the plug 100 and the socket 200 abut against each other by the elastic force, the plug 100 or the socket 200 should be locked by the locking device, so as to prevent the plug 100 and the socket 200 from being separated. Under the combined action of the locking device and the pushing mechanism 400, not only can the plug 100 be tightly jointed with the socket 200, but also the shaking of the plug 100 relative to the socket 200 can be avoided.

Further, the plug 100 is provided with a first guiding mechanism 150, and the socket 200 is provided with a second guiding mechanism 230 adapted to the first guiding mechanism 150.
