[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-8 , the technical solution of the present invention: a current terminal connector anti-mistaken touch structure, including a terminal plug 1, a screw 2, a wire 3, an anti-mistaken touch cover 4, an integrated buckle 5, a plug plastic shell 6, an anti-open circuit clip 7, a compression spring 8, a short-circuit copper column 9, a short-circuit ejection strip 10, a terminal 11, a square nut 12 and a main body clip 13;

[0046] A screw 2 and an anti-mistaken touch cover plate 4 are installed on the left side of the terminal plug 1, a wire 3 is arranged above the terminal plug 1, an integrated buckle 5 is installed between the wires 3, a plug plastic shell 6 is installed below the integrated buckle 5, an anti-open circuit clip 7, a compression spring 8, a short-circuit copper column 9 and a short-circuit ejection strip 10 are installed on the inside of the plug plastic shell 6, and a terminal 11 is arranged below the plug plastic shell 6.

[0047] As a preferred technical solution of the present invention, the terminal plug 1 is locked above the anti-mistaken touch cover plate 4 by a screw 2, and the anti-mistaken touch cover plate 4 has an installation foolproof structure, and the front and back sides are clearly marked to prevent the anti-mistaken touch cover plate 4 from being installed upside down. The wire 3 is sleeved on the current terminal through a combination bolt, and then the wire 3 is clamped into the wire clamping groove of the anti-mistaken touch cover plate 4;

[0048] The main body clip 13, the anti-open circuit clip 7 and the square nut 12 are installed in the plug plastic shell 6. After the short-circuit ejector strip 10 is installed in the plug plastic shell 6, one end of the compression spring 8 is installed on the positioning column of the plug plastic shell 6, and the other end is fixed in the groove of the short-circuit copper column 9 to form an anti-open circuit component. The anti-open circuit component is installed in the plug plastic shell 6, and the undercut on the integrated buckle 5 fixes the anti-open circuit component to the plug plastic shell 6;

[0049] After the anti-open circuit clip 7 in the plug plastic shell 6 is installed, it is connected to the left and right sides under the action of its own elastic force, so that the circuits in the left and right directions can be short-circuited; after the anti-open circuit component is installed in the plug plastic shell 6, the short-circuit copper column 9 is connected to the anti-open circuit clip 7 under the thrust of the compression spring 8, so that the upper and lower circuits can be short-circuited;

[0050] When the wire 3 is inserted into the terminal plug 1, the anti-open circuit clips 7 connected to the left and right are pushed open by the top column of the terminal post 11, and the short-circuit ejection bar 10 is also pushed upward. After the short-circuit ejection bar 10 pushes the short-circuit copper column 9 to move upward, the short-circuit copper column 9 is separated from the anti-open circuit clip 7, so that all short-circuit structures are disconnected after the terminal plug 1 is inserted. When the terminal plug 1 is pulled out, the anti-open circuit clips 7 are short-circuited in pairs on the left and right under the action of their own elastic force. When the terminal plug 1 is pulled out, the short-circuit copper column 9 is short-circuited in the upper and lower directions with the anti-open circuit clip 7 under the thrust of the compression spring 8, so that the terminal can realize multiple short-circuit connections at the same time, meeting the terminal connection diversity.
