Embodiment 1

[0065] The invention provides a DC plug-in device for a plug and a socket, such as figure 1 As shown, a mechanical switch 4 is set in the socket, and the opening and closing control is performed by a mechanical starting mechanism 7; an electronic switch mechanism 9 that can control the start and close of the load 10 is set in the DC electrical appliance; The plug is equipped with a linkage switch 8 with a locking function, which can control the mechanical switch 4 in the socket and the load 10 of the DC electrical appliance, and realize the reliable insertion of the plug and the socket through mutual locking, so as to avoid problems caused by improper insertion. Poor contact is caused to generate electric arc, which endangers the safety of electricity consumption.

[0066] Specifically, such as figure 2 As shown, a DC plug-in device for a plug and socket includes: a DC socket 1, a DC plug 2 and a DC electrical appliance 3; the DC socket 1 is provided with a mechanical switc...

Embodiment 2

[0073] A method based on the insertion of a plug into a DC socket in an arc-extinguished state, such as image 3 shown, including:

[0074] Step 1: With the insertion of the DC plug 2, the latch 8 on the DC plug 2 controls the DC load 3 from connected to disconnected;

[0075] Step 2: the latch 8 controls the action of the mechanical switch activation mechanism 7 in the DC socket 1, and then controls the mechanical switch 4 from disconnection to closure;

[0076] Step 3: As the DC plug 2 continues to be inserted until it is fully pushed into place, the latch 8 is connected to the DC appliance 3, and at the same time the latch 8 triggers the closing of the load starting mechanism 9, and the DC appliance 3 is energized.

[0077] Step 1 includes: the latch 8 enters the recess on the side wall of the DC plug 2, compresses the first spring 15, and simultaneously drives the switch 16 from closed to open; at this time, the middle circuit of the DC consumer 3 is closed, and the mecha...

Embodiment 3

[0082] A method based on the extraction of the plug from the DC socket in an arc-extinguished state, such as Figure 5 shown, including:

[0083] Step A: As the DC plug 2 is pulled out, the latch 8 on the DC plug 2 controls the DC load 3 from connected to disconnected;

[0084] Step B: the latch 8 controls the action of the mechanical switch activation mechanism 7 in the DC socket 1, and then controls the mechanical switch 4 from closing to opening;

[0085] Step C: As the DC plug 2 continues to be pulled out until it is completely separated, the latch 8 triggers the load starting mechanism 9 to control the DC consumer 3 from disconnection to connection.

[0086] Step A includes: the latch 8 enters the recess on the side wall of the DC plug 2, compresses the first spring 15, and simultaneously drives the switch 16 from closed to open; at this time, the circuit of the DC consumer 3 is closed, and the mechanical switch 4 is in the closed state.

[0087]Step B includes: as the...

Abstract

The invention provides a direct-current plugging device and method for a plug and a socket. The direct-current plugging device comprises the direct-current socket (1), the direct-current plug (2) and a direct-current electric appliance (3). A mechanical switch (4) and a mechanical switch starting mechanism (7) are arranged in the direct-current socket (1), and the mechanical switch starting mechanism (7) is connected with the mechanical switch (4); a clamping lock (8) is arranged in the direct-current plug (2); a load starting mechanism (9) is arranged in the direct-current electric appliance (3); the clamping lock (8) is respectively in contact connection with the load starting mechanism (9) and the mechanical switch starting mechanism (7); the clamping lock (8) controls the opening / closing of the load starting mechanism (9) and further controls the opening / closing of the mechanical switch (4) by controlling the mechanical switch starting mechanism (7) so as to realize the arc extinguishing in the plugging process of the device. Arc-free plugging and separation of the plug and the socket are realized, arc burning is avoided, and the service life of the direct-current plug and the socket is prolonged.

Description

technical field [0001] The invention relates to the technical field of power distribution and utilization, in particular to a DC plug-in device and method for a plug and a socket. Background technique [0002] In daily electrical equipment such as home appliances, most of its internal circuits are driven by DC power, and power conversion circuits need to be configured inside the electrical appliances to achieve AC-DC conversion. With the development of power electronics technology, it has become possible to provide stable and reliable DC power for electrical equipment. Direct power supply of DC electrical appliances can save the AC-DC conversion circuit with low energy efficiency, which can not only save the manufacturing cost of electrical appliances, but also save energy. , has received widespread attention. However, unlike alternating current, direct current does not alternate, and its current waveform does not have a zero-crossing point. When a working DC power device i...
