Abstract
The utility model relates to a grounding device adopting a flexible connection mode. The grounding device mainly comprises a braided wire, a first crimping copper sheet and a second crimping copper sheet, and two ends of the braided wire, the first crimping copper sheet and the second crimping copper sheet are respectively formed in a molecular diffusion welding manner. The braided wire is a bare copper wire or a tinned copper braided wire. The grounding device is simple in process, convenient to connect, good in safety, high in reliability and low in cost.
Description
Technical field
The utility model belongs to dynamo-electric manufacturing field, particularly a kind of earthing device of the mode that is flexible coupling.
Background technology
In the past, generally be through 2.5mm between instrument door, actuating doors and the earth in the conventional complete sets of electric switchgears and control devices switch cubicle
2Yellow and green BV line connect.With being shaped with the crimping of colding pressing of o shape copper sleeve respectively after the two ends strip off of yellow and green, realize connection with screw two is fastening again.Because the outer layer insulation material of yellow and green is a polyvinyl chloride rubber, external diameter is bigger, be difficult for flexible crooked, the instrument door of this connected mode, actuating doors will inevitably because of through hold-open door, closing the door causes connecting line stretcher strain, even joint comes off.Thereby lose the effect of ground protection.
The utility model content
The technical problem that the utility model will solve provide a kind of can be with the novel grounded device of instrument door, actuating doors reliable ground.
A kind of earthing device of the mode that is flexible coupling, the critical piece of this earthing device are litzendraht wire, crimping copper sheet one, crimping copper sheet two; The molecular diffusion welding forming is passed through with crimping copper sheet one, crimping copper sheet two respectively in said litzendraht wire two ends.
Litzendraht wire is bare copper wire or tin-coated copper litzendraht wire.
The utility model technology is simple, and easy-to-connect, security performance are good, and cost is lower.Adopt the earth protective device of this mode that is flexible coupling, effect is obvious, can extensively promote.
Description of drawings
Fig. 1 is the structural representation of the utility model earthing device;
Embodiment
The continuous ground protective device that is flexible coupling after the improvement, because its critical piece is zinc-plated litzendraht wire, flexible easily crooked, pliability is good, flexibility is big.Being connected between the instrument door, actuating doors that it is used for the complete sets of electric switchgears and control devices and the earth earth electrode,, more can not come off even through hold-open door, closing the door can not cause connecting line stretcher strain yet.Therefore through this improvement, can effectively overcome above-mentioned defective.
As shown in Figure 1, the earthing device of the mode that originally is flexible coupling, its critical piece--tin-coated copper litzendraht wire 1 is applicable to that Related products such as various high and low voltage electrical equipment elements, complete sets of electric switchgears and control devices cabinet door, mine explosion-proof switch do the usefulness that is flexible coupling.Core material adopts bare copper wire or tin-coated copper braid over braid (twisted wire), is that copper foil laminate is partly forced together, and adopts the molecular diffusion welding, through big current flow heats pressure welding moulding.Have anti-oxidation characteristic, litzendraht wire 1 adopts high-quality circular copper wire (0.10,0.15; 0.20) or zinc-plated soft circular copper wire (0.10; 0.15) form through single or multiple lift braiding with multiply (24.36.48 ingot), even wherein annealed copper wire comes off even breaks, its integral body remains a lead; Will play the effect of lead, also just can not lose important ground protection effect certainly.Litzendraht wire 1 can be straight line, but also coiled spring-like.The electrical technology performance satisfies standard (JB2572-79).The molecular diffusion welding forming is passed through with crimping copper sheet 1, crimping copper sheet 23 respectively in litzendraht wire 1 two ends, uses tapping screw fastening again, has so just formed a complete continuous ground protective device that is flexible coupling.
It is simple especially that the utility model is made, and is connected firmly, conduction property is good, capable of expansion and contraction.It is used for instrument door, the actuating doors of the complete sets of electric switchgears and control devices and after the earth earth electrode is connected, can be grounded the continuity of protection, guarantee operating maintenance personnel's safety.
Claims (2)
1. the earthing device of the mode that is flexible coupling, it is characterized in that: the critical piece of said earthing device is litzendraht wire (1), crimping copper sheet one (2), crimping copper sheet two (3); The molecular diffusion welding forming is passed through with crimping copper sheet one (2), crimping copper sheet two (3) respectively in said litzendraht wire (1) two ends.
