specific Embodiment 1

[0068] The wire clip hardware of this embodiment is used for the conductive connection of the six-split wires and the terminal board 3 . Such as Figure 1 to Figure 4 As shown, the clamp hardware includes two clamp bodies 1 and six cable pressing blocks 2. The clamp body 1 is provided with a cable groove 11 and a terminal connection structure. The clamp body 1 is Z-shaped as a whole, including two The support plates parallel to each other and the intermediate connection plate connecting the two support plates, the cable groove 11 and the terminal connection structure are respectively arranged on the two support plates. There are three cable slots 11 on each clamp body 1 , and the cable pressing block 2 , the cable slots 11 and the cables 5 are in a one-to-one correspondence.

[0069] Such as figure 2 and Figure 4 As shown, the cable clamping block 2 is provided with a cable clamping groove 21, and both the cable clamping groove 11 and the cable clamping groove 21 are used...

specific Embodiment 2

[0076] The terminal connection plate in the above-mentioned implementation 1 is a rectangular plate, the sealing ring groove as a whole includes four parts, and the four parts correspond to the four sides of the rectangular plate one by one, and the elastic sealing member is a sealing ring. The elastic seal in this embodiment includes four sealing strips, and the four sealing strips correspond to the four parts of the sealing ring groove one by one, that is, each part of the sealing ring groove is respectively equipped with a sealing strip, so that the crimping surface of the terminal board and the wiring An annular sealing area is formed between corresponding sides of the terminal board.

specific Embodiment 3

[0078] In the above-mentioned embodiment 1, an anti-corrosion layer and a fluorocarbon coating are provided on the non-conductive surface of the metal fittings of the terminal connecting plate. In this embodiment, only an anti-corrosion layer is provided on the non-conductive surface of the fittings of the terminal connecting plate.

Abstract

The invention relates to a wire clamp fitting and a wire clamp fitting connecting structure, and the wire clamp fitting comprises two wire clamp bodies, each wire clamp body comprises a terminal connecting plate, and the terminal connecting plates of the two wire clamp bodies are connected through a bolt so as to clamp and fix a wiring terminal plate; the terminal connecting plate is provided witha terminal plate crimping surface, and the terminal plate crimping surface is used for being in conductive contact with the corresponding side surface of the wiring terminal plate; and the crimping surface of the terminal plate is provided with a sealing ring groove. The wire clamp fitting also comprises an elastic sealing element, and the elastic sealing element is used for being installed in the sealing ring groove, so as to form an annular sealing region between the corresponding side surface of the wiring terminal plate and the crimping surface of the terminal plate. The sealing ring groove is provided with an accommodating space in which the elastic sealing piece which is extruded to deform is completely embedded, and when the terminal connecting plate clamps and fixes the wiring terminal plate, the accommodating space enables the elastic sealing piece to be completely embedded into the sealing ring groove, so that the corresponding side surface of the wiring terminal plate is inconductive contact with the crimping surface of the terminal plate. The conductive contact surface oxidation in the long-term use process is avoided.

Description

technical field [0001] The invention relates to a wire clamp hardware and a connection structure of the wire clamp hardware. Background technique [0002] At present, the domestic power demand is increasing day by day, the capacity and carrying capacity of the conventional converter station can not meet the actual demand gradually, and its clamp fittings can not meet the requirements of the new UHV DC converter station. [0003] For example, the wire clip hardware disclosed by the invention patent of CN105048130B with the authorized notification number includes an upper splint, a lower splint and a wire clip cover. Both the upper splint and the lower splint are L-shaped plates, and the terminal board is clamped between the vertical plates of the two splints. The upper splint and the lower splint are used as the cable clamp body, and the cable clamp cover is used as a cable clamp, and the cable is pressed and fixed on the cable clamp body by the cable clamp. [0004] With t...
