Embodiment Construction
[0013] Such as figure 1 , figure 2 , image 3 As shown, put the hexagon bolt 3 and the butterfly spring washer 4 into the through hole of the male ferrule 1, and then snap the stop washer 5 into the polished rod part of the hexagon bolt 3. In this way, the cold-pressed joint with bolts is assembled; then the two cables 6 are respectively connected to the terminal of the male cold-pressed terminal 1 and the terminal of the female cold-pressed terminal 2 in a cold-pressed manner. Finally, connect the male cold-pressed terminal 1 and the female cold-pressed terminal 2 firmly with bolts.

The invention discloses a cold press connector lug device for a high voltage. One end of a male cold press connector and one end of a female cold press connector have a cylindrical structure respectively, while the other ends have a half-cylindrical structure respectively; a half-cylinder of the male cold press connector is in matching connection with a half-cylinder of the female cold press connector through a plurality of bolts to form a complete cylindrical structure; the bolts match with a papilionaceous spring washer and a stop washer fixedly connect the male cold press connector; and the bolts are hidden in the cylinder. The cold press connector lug device has the advantages that: 1, one end of a cold press head is cylindrical, while the other end is half-cylindrical, the whole bolts are hidden in the cylinder, and because the whole cold press connector lug device has a cylindrical appearance, local discharges are greatly reduced, and the cold press connector lug device is suitable for high voltage occasions; and 2, the cold press connector lug device effectively prevents the bolts, the washer and other small objects from falling down so as to thoroughly put an end to the occurrence of hidden troubles.
Description
technical field [0001] The invention relates to a terminal device, in particular to a high-voltage cold-pressed terminal device. Background technique [0002] When installing high-voltage electrical appliances, it is often necessary to connect the separated high-voltage lead wire ends with bolts or screws. Since the bolts and washers used for connection are small items, it is easy to drop them inside the high-voltage electrical appliances during installation, thus causing accident hazards. Contents of the invention [0003] The purpose of the present invention is to provide a high-voltage cold-pressed terminal device, when the cold-pressed terminals of the device are connected to each other, because the bolts, washers, etc. are already on the male cold-pressed terminals, and due to the Bolts, washers, etc. will not fall off due to the action of the moving washer. Completely put an end to the occurrence of hidden dangers. [0004] The present invention is realized in thi...
