Abstract
The invention discloses a cable coupler, which comprises a first coupling rod and a second coupling rod which are mutually and vertically coupled. At least a first U-shaped groove is arranged on the first coupling rod, at least a second U-shaped groove is arranged on the second coupling rod, and the opening direction of the second U-shaped groove is opposite to the opening direction of the first U-shaped groove; the cable coupler is made by adopting AS alloy (magnesium, zinc, and aluminum-rare earth alloy) through die casting formation, and the tempering treatment is performed. The operation of the cable coupler is simple, after a cable is put into U-shaped grooves, groove openings are closed by utilizing a wire crimper, to ensure the cable and the cable coupler to be coupled into a whole;the coupling is firm, the contact resistance is low, and the low contact resistance can be maintained for a long time; the material of the cable coupler is firm and durable, underground corrosion resistant and long-term and reliable.
Description
Technical field
The present invention relates to a kind of terminal connector spare of cable, especially a kind of terminal connector spare that is used for high-grade railway combined grounding system Through ground wire.
Background technology
In the high-speed railway engineering of China's speed per hour more than 200 kilometers, respectively be laid with a Through ground wire in the cable trough of the left and right sides, downline road, the every interval of Through ground wire laterally connects once for 100 meters.The effect of Through ground wire is to set up an each point current potential basically identical, earth resistance less than 1 Ω and ground network reliably steady in a long-term in railway overall length scope, make the external metallization member ground connection of various electric equipments, plant equipment and safeguard, guarantee the personal safety of personnel on the normal operation of equipment and the train.
Generally be that to tie up and coat in the tie part outside shrink sleeve with copper wire anticorrosion or adopt the connecting mode connection of the metal clip that power cable conductor connects between the Through ground wire that existing downline lays and the Through ground wire that laterally connects, these connecting modes exist anti-underground corrosion poor, long-term work contact resistance instability, problems such as complex operation continue.
Summary of the invention
The present invention has overcome the deficiency in the existing Through ground wire connection technique, provides a kind of simple to operation, firm in structure, anti-corrosion, the cable coupler that contact resistance is low.
The present invention is achieved in that a kind of cable coupler, comprise two vertical mutually first coupling bar and second coupling bars that connect, described first coupling bar is provided with at least one first " U " shape groove, described second coupling bar is provided with at least one second " U " shape groove, and the opening direction of described second " U " shape groove is opposite with the opening direction of described first " U " shape groove.
The place, both ends of described first coupling bar is provided with described first " U " shape groove; The place, both ends of described second coupling bar is provided with described second " U " shape groove.
Described cable coupler adopts AS alloy (magnesium zinc-aluminium-rare earth alloy) to make through die cast, and temper.
Compared with prior art, advantage of the present invention is: this cable coupler is simple to operate, cable is put into " U " shape groove after, even use Crimping Pliers that notch closure cable and cable coupler are become one; Connect firmly, contact resistance is low, and can keep low contact resistance for a long time; Sturdy and durable, the anti-underground corrosion of cable connection modulator material, reliably and with long-term.

Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing and concrete execution mode:
Referring to Fig. 3, Fig. 4, Fig. 5, a kind of cable coupler, it comprises two vertical mutually first coupling bar 1 and second coupling bars 2 that connect, described first coupling bar 1 is provided with at least one first " U " shape groove 11, described second coupling bar 2 is provided with at least one second " U " shape groove 21, and the opening direction of described second " U " shape groove 21 is opposite with the opening direction of described first " U " shape groove 11.
In the present embodiment, place, the both ends of described first coupling bar 1 is provided with described first " U " shape groove 11; The place, both ends of described second coupling bar 2 is provided with described second " U " shape groove 21.
Described cable coupler adopts AS alloy (magnesium zinc-aluminium-rare earth alloy) to make through die cast, and temper.
The using method of this cable coupler is as follows: power taking cable coupling, with horizontal tie 22 put into second " U " shape groove 21, Through ground wire 12 is put into first " U " shape groove 11, even with Crimping Pliers the closed described horizontal tie 22 of each notch, Through ground wire 12 are become one with cable coupler.First " U " shape groove 11 shows among the figure is state after the closure, and second " U " shape groove 21 shows is state before closed.
