The utility model discloses a connection device of a choke transformer and a steel rail. The connection device comprises a wiring board, a lead wire and a plug pin, wherein a T-shaped connection sheet is arranged on the wiring board; a vertical section of the T-shaped connection sheet is a fixed end extending from the wiring board; a horizontal section of the connection sheet covers the vertical section of the T-shaped connection sheet along an external diameter of the lead wire; and a wire head of the lead wire is welded on the vertical section of the connection sheet by argon arc welding. The lead wire is in the overlap joint by arranging the T-shaped connection; both ends of the horizontal section are rolled up to cover the lead wire; and the wire head of the lead wire is welded on the vertical section of the connection sheet by the argon arc welding. Both ends of the horizontal section are firmly welded with the lead wire by the argon arc welding, thereby improving welding fastness. A semispherical groove is arranged at the top of a through hole of the plug pin so as to increase effective welding area between the lead wire and the plug pin.
Description
Technical field
The utility model relates to jockey, more precisely, relates to the jockey between a kind of choke transformer and the rail, is the infrastructure device of railway electrification section signal track circuit.
Background technology
Choke transformer etc. the resistance lead wire be the infrastructure device of railway electrification section signal track circuit, choke transformer and rail that its effect will be installed in railway next door exactly link together, and are made up of 2 long lines and 2 short-terms.The resistance value of long line and short-term equates.Resistance connecting lines such as a large amount of chokes that use of present domestic high ferro adopt wick steel wire rope outsourcing low-carbon steel line and red copper wire, stranded after outsourcing insulating sleeve again, but long line is identical with the interior different sectional areas of copper content of short-term.Lead wire adopts oxygen welding with the welding of terminal block (choke transformer is connected usefulness), and lead wire adopts electric welding with the welding of plug pin (rail is connected usefulness).
Along with the development of railway transportation, the especially continuous development of heavy haul railway and high-speed railway, the capacity of choke transformer is also in continuous increase, and choke transformer is connected the line footpath sectional area that waits the resistance lead wire of usefulness also in continuous increase with rail.Continue to adopt above-mentioned connection can have following problem: because the material that terminal block adopts is a copper plate; The material that plug pin adopts is a round steel; And the material of lead wire is steel strand wire and red copper wire, and the fusing point during the unlike material welding is inequality, and it is welded direct to together; Can cause some areas to weld, the bad phenomenon of some areas welding.Make terminal block or plug pin in long-term use, come off easily.
The utility model content
The utility model provides the jockey of a kind of choke transformer and rail in order to solve the problem that exists in the prior art, and it is simple in structure, can make lead wire more firm with being connected of terminal block, has solved the problem that comes off after the long-time use effectively.
The technical scheme of the utility model is: the jockey of a kind of choke transformer and rail; Comprise terminal block, lead wire, plug pin; Said terminal block is provided with T shape brace; The vertical section of said T shape brace is a stiff end that terminal block extends out, and the horizontal segment of said brace wraps it along the external diameter of lead wire, and is welded on the vertical section of brace through argon arc welding the end of a thread with lead wire.
Preferably: the two ends of said brace horizontal segment are fixed together through argon arc welding and lead wire.
Preferably: the top of said plug pin through hole is provided with hemispherical groove.
The beneficial effect of the utility model is: connect through T shape is set, lead wire is costed, the two ends of horizontal segment are rolled and are wrapped lead wire, and the mode through argon arc welding is welded on the end of a thread of lead wire on the vertical section of brace then.The two ends of horizontal segment are welded with lead wire through the mode of argon arc welding and extremely are in the same place, and have improved the fastness of welding.At the top of plug pin through hole a hemispheric groove is set, has increased the efficient weld area of lead wire and plug pin.Simultaneously, adopt argon arc welding can improve the quality of welding, avoided the oxidation, scaling loss of metal etc.The arc burning of argon arc welding is stable, and heat is concentrated, and the arc column temperature is high, and the heat affected area is narrow, and the weldment stress that is welded, distortion, crackle are inclined to little.
Description of drawings
Fig. 1 shows the front view of the utility model.
Fig. 2 shows the vertical view of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Choke transformer etc. resistance lead wire 2 by wick steel strand wire outsourcing low-carbon steel line with red copper wire is stranded forms, the outer bag of lead wire insulating sleeve, two ends are connecting terminal block 1 and plug pin 3 respectively.
Like Fig. 1, shown in Figure 2, lead wire 2 comprises long line 21 and short-term 22, and its resistance value equates.Terminal block 1 is provided with a brace, comprises vertical section 41 and horizontal segment 42, and is whole T-shaped.Said terminal block 1 can be one-body molded with brace, also can make up, and what this execution mode was selected is integrated.The vertical section 41 of said brace is a stiff end that extends out from terminal block 1; When connecting; Lead wire 2 is passed the horizontal segment 42 of brace; And ride on the vertical section 41, the two ends of horizontal segment 42 are rolled and wrapped lead wire 2, the mode through argon arc welding is welded on the end of a thread of lead wire 2 on the vertical section 41 of brace then.Certainly, the two ends of horizontal segment 42 also can be welded with lead wire through the mode of argon arc welding and extremely are in the same place, and have improved the fastness of welding.
Traditional welding manner is electric welding, and such welding makes the lead wire contact resistance increase, and the resistance value that can make growth line and short-term is unequal.Do not cancel each other the time when traction current bigger in the track circuit, cause the choke transformer core sataration easily, influence the operate as normal of track circuit through choke transformer.Adopt argon arc welding just can overcome this problem, the position of its welding mode with its fusion is welded together, can reduce the contact resistance of lead wire.Wherein this welding manner of argon arc welding belongs to prior art, no longer specifies at this.
Top at plug pin 3 through holes is provided with hemispheric groove, and lead wire 2 welds it in groove after passing the plug pin through hole, has increased the efficient weld area of lead wire and plug pin equally.
When electrified sections 50Hz traction current gets into the choke transformer traction end through rail and through resistance lead wires such as choke transformers; Because the long line of lead wire and short-term resistance value equate, and two traction circle equal turn numbers are in the opposite direction about the choke transformer, the magnetic direction of generation is cancelled each other on the contrary; Can not produce interference voltage; Owing to adopted above-mentioned brace, make terminal block and plug pin head can not come off, guaranteed the reliable operate as normal of track circuit.In railway, use said apparatus in a plurality of high ferro track circuit sections, each item index all satisfies the requirement of iron mark, through long-term use fault does not take place, and has guaranteed traffic safety.
The above is merely the utility model preferred implementation, is not the practical range that is used for limiting the utility model, and the equivalence of in the protection range of the utility model, being done in every case changes and modifies, and all should think to have fallen in the protection range of the utility model.
