Description

Technical Field

[0001] The utility model belongs to the technical field of power connection equipment, and more specifically relates to a frame edge type socket with an arc-proof structure. Background Art

[0002] In electrical engineering, when the voltage between two conductors breaks through the air layer to form an arc, the air will produce a large number of electrons after the arc is formed, and the conductivity will increase rapidly. Even if the distance between the two conductors continues to increase, the arc cannot be extinguished. This phenomenon is called arc pulling.

[0003] When plugging and unplugging ordinary sockets, because the copper sheets are in charged contact and separation, arcs or even sparks will be generated at the moment of plugging and unplugging, which can easily cause electric shock accidents or even current breakdown problems. In certain occasions, such as places where there are flammable gases such as gas, oil and gas in the air, fires or even explosions will occur, which are extremely dangerous. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a frame-edge socket with an anti-arcing structure, which can prevent arcing when the socket is in the on and off states, thereby preventing the insulation performance of electrical appliances and equipment from being reduced.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A frame-edge socket with an anti-arcing structure, the frame-edge socket comprising a socket body, the socket body comprising an input terminal, an input elastic contact piece, the input elastic contact piece is connected to the input terminal through an input terminal wiring board; comprising an output terminal, an output elastic contact piece, the output elastic contact piece is connected to the output terminal through an output terminal wiring board; an anti-arcing structure is provided between the input terminal and the output terminal in the socket body, the anti-arcing structure comprises left and right parts, an insulating partition is provided in the middle of the anti-arcing structures of the left and right parts, and the left and right parts of the anti-arcing structure are symmetrically arranged relative to the insulating partition.

[0007] Furthermore, the arc-strike prevention structure includes an arc-striking piece and an arc-extinguishing mechanism, one end of the arc-strike piece is adjacent to the top of the arc-extinguishing mechanism, and the other end is close to the outlet terminal wiring board and the inlet terminal wiring board.

[0008] Furthermore, the arc extinguishing mechanism has a J-shaped appearance, with inner and outer arc guide plates arranged at intervals to form an arc guide groove in the middle.

[0009] The beneficial effects of the utility model are as follows: an arc-pulling prevention mechanism is added to the frame-edge socket; the arc-pulling prevention structure includes an arc-striking piece and an arc-extinguishing mechanism; due to the action of the arc-striking piece, the arc generated by the incoming elastic contact piece and the outgoing elastic contact piece is led out through the incoming terminal wiring board and the outgoing terminal wiring board to prevent the arc from corroding the conductive seat piece, and the led-out arc is guided into the arc-extinguishing mechanism by the arc-striking piece, and the arc-extinguishing mechanism weakens the arc through the J-shaped track, so that the arc loses potential energy during the climbing process until it is extinguished.

DETAILED DESCRIPTION

[0014] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 3 As shown, a frame-edge socket with an anti-arcing structure, the frame-edge socket includes a socket body 1, the socket body 1 includes an input terminal 2, an input elastic contact piece 3, the input elastic contact piece 3 is connected to the input terminal 2 through an input terminal wiring board 4; includes an output terminal 5, an output elastic contact piece 6, the output elastic contact piece 6 is connected to the output terminal 5 through an output terminal wiring board 7; an anti-arcing structure 8 is provided between the input terminal 2 and the output terminal 5 in the socket body 1, the anti-arcing structure 8 includes two left and right parts, an insulating partition plate 9 is provided in the middle of the left and right parts of the anti-arcing structure 8, and the left and right parts of the anti-arcing structure 8 are symmetrically arranged relative to the insulating partition plate 9.

[0016] The arc-pulling prevention structure 8 includes an arc-striking piece 10 and an arc-extinguishing mechanism 11, one end of the arc-striking piece 10 is adjacent to the top of the arc-extinguishing mechanism 11, and the other end is close to the outgoing terminal block 4 and the incoming terminal block 7; the arc-extinguishing mechanism 11 is J-shaped in appearance, and the inner and outer arc-guiding plates 12 are arranged at intervals, and an arc-guiding groove 13 is formed in the middle. Specifically, the arc-striking piece 10 is close to the arc-guiding plate 12 of the arc-extinguishing mechanism 11 close to the insulating partition 9 and close to the inside of the arc-guiding groove 13.

[0017] When the frame-edge socket is connected and disconnected, the elastic contact piece will generate current. This phenomenon is caused by the current breaking through the air to generate an arc. Due to the action of the arc-starting piece, the generated arc will be attracted to the arc-starting piece for conduction. The end of the arc-starting piece is adjacent to the arc-extinguishing mechanism, and the conducted arc enters the arc-extinguishing mechanism. The arc-extinguishing mechanism weakens the arc through the J-shaped track, causing the arc to lose potential energy during the climbing process until it is extinguished. The insulating partition separates the arcs generated by the incoming and outgoing ends to prevent short circuits.

[0018] The above description is only a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made using the contents of the present utility model specification, or directly or indirectly applied to the technical field of other related products, are also included in the patent protection scope of the present utility model.
