Abstract
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
The present invention relates to a kind of connector lug device, relate in particular to a kind of cold press connector lug device for high voltage.
Background technology
When installing, High-Voltage Electrical Appliances often the high-voltage connection termination that separates need be connected with each other with bolt or screw.Because the bolt of connection usefulness, packing ring etc. all are some tiny article, be easy to when mounted it is dropped in High-Voltage Electrical Appliances inside, thus the hidden danger of causing the accident.
Summary of the invention
The object of the present invention is to provide a kind of cold press connector lug device for high voltage, this device cold pressing terminal stud when interconnecting, because bolt, packing ring etc. are all on public cold weld line end, and owing to there are the effect bolt, packing ring etc. of stop washer can not fall down.Thoroughly stopped the generation of hidden danger.
The present invention is achieved like this, it comprises public affairs cold pressing joint, mother cold pressing joint, bolt, butterfly bullet pad, stop washer, it is characterized in that a cold pressing end of joint and female joint of colding pressing of public affairs is a cylindrical structural, the other end is a half cylindrical structure, the cold pressing semicolumn of joint of public affairs forms complete cylindrical structural by several bolts cold pressing semi-cylindrical in configuration of joint of mother that is connected, described bolt cooperates butterfly bullet pad to fixedly connected the public affairs joint of colding pressing with stop washer, and bolt is hidden in the cylinder.
Cold pressing semicircular platform half counter bore hole diameters of joint of described mother is slightly larger than the diameter of stop washer, and the degree of depth of half counterbore is greater than the thickness of stop washer.
Cold pressing platform half counter bore hole diameters of semicircular structure of joint of described public affairs is slightly larger than the diameter of bolt, and half counterbore deep hole is identical or smaller with butterfly bullet mat thickness with bolt head.
Described stop washer internal diameter is slightly larger than the bolt light rod external diameter, and less than the bolt thread external diameter, and the stop washer external diameter is greater than the public affairs joint through-hole diameter of colding pressing, and the stop washer breach is slightly less than the bolt light rod external diameter.
Technique effect of the present invention is: the first end of 1, colding pressing is cylindrical, and the other end is half-cylindrical, and whole bolt is hidden in the cylinder, because that whole cold weld line apparatus appearance is is cylindrical, thereby greatly reduces partial discharge, is suitable for the high voltage occasion; 2, prevent that effectively wisps such as bolt and packing ring from can not fall down, and thoroughly stopped the generation of hidden danger.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the enlarged drawing of A-A of the present invention.
Fig. 3 is the structural representation of stop washer of the present invention.
Cold pressing joint 2, mother cold pressing joint 3, hex bolts 4, butterfly bullet pad 5, stop washer 6, cable of public affairs in the drawings, 1,
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, hex bolts 3, butterfly bullet pad 4 are put into the cold pressing through hole of joint 1 of public affairs, then stop washer 5 is snapped in the polished rod part of hex bolts 3.The joint of colding pressing that has bolt has so just assembled; Then two cables 6 are adopted the mode of colding pressing to be connected on the terminal of the terminal of public cold press connector lug 1 and female cold press connector lug 2 respectively.At last public cold press connector lug 1 and female cold press connector lug 2 usefulness bolts are connected firmly.
