The first described binding post, the second binding post are equipped with the apical pore that communicate vertical with cable connecting hole.
Described apical pore is screwed hole.Can securing member be connected in apical pore, for holding out against after insert cable in cable connecting hole, avoid deviating from of cable.
The second described binding post is divided into enlarged diameter section, reduced diameter section, and reduced diameter section is external thread rod, offers axial cable connecting hole in the middle part of described enlarged diameter section; Described enlarged diameter section is connected by tapering transition section with between reduced diameter section.
The opening part of the cable connecting hole of the first described binding post is provided with concentric bellmouth, and the bellmouth of the first binding post and the tapering transition section of the second binding post match.
Described insulating part comprises insulating paper, is coated at the insulation casing of insulating paper, first binding post, the second binding post, expose to the equal wrap insulate paper in periphery of the cable of the first binding post or the second binding post, described insulation casing is coated on the insulating paper of the first binding post, the second binding post periphery.
Second binding post, the first binding post coordinate and form binding post, binding post, expose to the cable periphery wrapping inner layer insulating paper of binding post, and the length of insulation casing is less than or equal to binding post length.
The primary insulation paper of insulation casing periphery and outer end thereof is equipped with outer layer insulation paper.
Insulation casing is shorter than binding post, insulation casing is positioned at the axial centre position of binding post, the primary insulation paper at the two ends of binding post is made to expose to insulation casing, and outer layer insulation paper is wound around on the primary insulation paper exposed, increase the bonding strength between cable and binding post, realize reliably insulating.
Beneficial effect: the technical program is without the need to securing member; the primary insulation paper of first, second binding post is close to without the need to removing during dismounting; and primary insulation paper has the protection of insulation casing; when removing outer layer insulation paper; primary insulation paper can not be damaged; therefore make the on-the-spot transformer dew empty time obviously shorten, thus the performance of transformer obtain guarantee.

Embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1, 2, 3, the utility model comprises the first binding post 1, second binding post 2; Be located at the insulating part of the first binding post 1 and the second binding post 2 outward; The two ends of the first binding post 1 are respectively equipped with cable connecting hole, internal thread hole; One end of second binding post 2 is provided with the external thread rod matched with the first binding post 1 internal thread hole, and the other end is provided with cable connecting hole.
Wherein, the second binding post 2 is divided into enlarged diameter section, reduced diameter section, and reduced diameter section is external thread rod, offers axial cable connecting hole in the middle part of enlarged diameter section; Be connected by tapering transition section between enlarged diameter section with reduced diameter section.
The opening part of the cable connecting hole of the first binding post 1 is provided with concentric bellmouth, and the bellmouth of the first binding post 1 and the tapering transition section of the second binding post 2 match.
Insulating part comprises insulating paper 4, is coated at the insulation casing 3 of insulating paper 4, first binding post 1, second binding post 2, expose to the equal wrap insulate paper 4 in periphery of the cable 5 of the first binding post 1 or the second binding post 2, insulation casing 3 is coated on the insulating paper 4 of the first binding post 1, second binding post 2 periphery.
