Description
Technical Field
The utility model relates to an electric power fitting technical field, concretely relates to and ditch type lightning protection fastener.
Background
The lightning protection piercing connector is a good high-voltage lightning protection device, is arranged on an overhead conductor near a high-voltage line insulator, when lightning overvoltage exceeds a certain value, flashover is caused between a piercing electrode arc leading arm and a grounding electrode of a lightning protection hardware fitting to form a short circuit channel, a continuous power frequency electric arc is moved to an arc burning arm of the connector to burn, and overvoltage energy is released to protect the conductor and the insulator from burning, so that the influence of lightning current is reduced to the lowest. The existing groove-combining type lightning protection wire clamp is unreasonable in structural design, so that the groove-combining type lightning protection wire clamp has the defects of complex structure, inconvenience in installation and unreliable performance.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, connect reliable, install convenient and ditch type lightning protection fastener.
For realizing above-mentioned mesh, the utility model discloses a and ditch type lightning protection fastener, including base, gland, bolt, discharge rod, base and gland between be provided with the branch line baffle, the bolt pass gland, branch line baffle in proper order and connect on the base, base and gland between be formed with the puncture line ball chamber, branch line baffle and base, gland between be formed with first centre gripping chamber and second centre gripping chamber respectively, the one end of discharge rod connect in first centre gripping intracavity, the bolt on correspond branch line baffle and gland between the department cover and be equipped with thrust spring.
The beneficial effect of above-mentioned structure is: be provided with thrust spring on the bolt, base and gland can press the bolt to unscrew under the effect of thrust spring and separate voluntarily under the state to be convenient for this and ditch type lightning protection fastener and thread, the installation of branch line, it is more convenient to install, and it is more convenient to use, thereby this and ditch type lightning protection fastener has simple structure, stable performance is reliable, connect reliable, install convenient advantage.
In particular, the base and the gland are respectively provided with piercing teeth corresponding to the piercing wire pressing cavities. The base and the gland are provided with the piercing teeth, so that the main line does not need to be peeled, and the installation is more convenient.
Particularly, sawtooth-shaped grooves are respectively formed in the gland, the branch line partition plate and the base corresponding to the first clamping cavity and the second clamping cavity. The gland, the branch line partition plate and the base are provided with sawtooth-shaped grooves, so that the lightning protection wire clamp is ensured to be more reliably contacted with the branch line and the discharge rod.
Particularly, a pressing strip is arranged on the bolt corresponding to the upper part of the gland, an arc-shaped groove is arranged on the pressing strip, and the arc-shaped groove is attached to the upper end face of the gland. The pressing strip can press the gland tightly, so that the clamping of the gland to the main line and the branch line is ensured to be more compact.

Detailed Description
As shown in fig. 1, the embodiment of the utility model provides a and ditch type lightning protection fastener, including base 10, gland 11, bolt 12, discharging rod 13, base 10 and gland 11 between be provided with branch line baffle 14, bolt 12 pass gland 11, branch line baffle 14 in proper order and connect on base 10, base 10 and gland 11 between be formed with puncture line ball chamber 101, branch line baffle 14 and base 10, gland 11 between be formed with first centre gripping chamber 102 and second centre gripping chamber 103 respectively, discharging rod 13's one end connect in first centre gripping chamber 102, bolt 12 on correspond and locate the cover to be equipped with thrust spring 15 between branch line baffle 14 and the gland 11. The base 10 and the gland 11 are respectively provided with piercing teeth 104 corresponding to the piercing and line pressing cavities 101. The base and the gland are provided with the piercing teeth, so that the main line does not need to be peeled, and the installation is more convenient. Sawtooth-shaped grooves 105 are respectively arranged on the gland 11, the branch line partition plate 14 and the base 10 corresponding to the first clamping cavity 102 and the second clamping cavity 103. The gland, the branch line partition plate and the base are provided with sawtooth-shaped grooves, so that the lightning protection wire clamp is ensured to be more reliably contacted with the branch line and the discharge rod. The bolt 12 is provided with a pressing strip 16 above the corresponding gland 11, the pressing strip 16 is provided with an arc-shaped groove 161, and the arc-shaped groove 161 is attached to the upper end face of the gland 11. The pressing strip can press the gland tightly, so that the gland is more compactly clamped corresponding to the main line and the branch line.
Be provided with thrust spring on the bolt, base and gland can press the bolt to unscrew under the effect of thrust spring and separate voluntarily under the state to be convenient for this and ditch type lightning protection fastener and thread, the installation of branch line, it is more convenient to install, and it is more convenient to use, thereby this and ditch type lightning protection fastener has simple structure, stable performance is reliable, connect reliable, install convenient advantage.
