The longitudinal field coil of working in nuclear fusion device, its electric current greatly to 100～200kA, magnetic field intensity reaches 2～3T, itself will produce electromagnetic force in very large face, again because of with other coil current and the plasma current outer electromagnetic force of generation face that interacts, also to make Demountable in such condition lower coil, common electric connection can not be satisfied the demand, add the space constraint of joint location, can not clamp perpendicular to the large-area direction of coil-conductor, therefore a kind ofly can meet the joint that the little and physical strength of resistance is high and do not take up space in the urgent need to developing simultaneously.
Summary of the invention
The object of this invention is to provide a kind ofly in large electric current, strong magnetic field circumstance work, can meet the detachable copper conductor joint that resistance is little and physical strength is high and do not take up space simultaneously.
The present invention realizes like this, the detachable connector of the dull and stereotyped copper conductor of a kind of large electric current, it comprises the copper coin at two ends, on the copper coin at two ends, slot into finger shape, in each groove, be inserted with and insert rod, in the middle of insertion rod, open circular hole and squeeze into register pin, on the copper coin at two ends, also have 2 slotted holes, insert rod and also opened accordingly 4 identical holes, be wherein used for installing tightening screw assembly near the hole of seam, the hole in outside is used for installing expansion bolt assembly.
Described register pin is interference fit with inserting excellent hole.
Described tightening screw assembly comprises high-intensity double threaded screw, 12 jiaos of self-locking nuts, packing ring, embedding key swivel nut, embedding key swivel nut is arranged in the corresponding screw of lower bolster, the bearing capacity being threaded for increasing the intensity that is threaded, increase screw thread stress surface, increase and fatigue resistance, shock-proof check.
Described expansion bolt assembly is made up of screw rod, some negative and positive expansion sleeves, opening long coat pipe, packing ring, 12 jiaos of self-locking nuts.
This joint also comprises upper padding plate, lower bolster, upper padding plate is arranged on the upper end of two ends copper coin, lower bolster is arranged on the lower end of two ends copper coin, expansion bolt assembly, tightening screw assembly and register pin are respectively through upper padding plate, lower bolster, the position that lower bolster is corresponding with expansion bolt assembly adds a stop screw, regulates the long coat pipe of expansion bolt and the degree of depth of bolt-inserting hole when expansion bolt is installed.
Advantage of the present invention is that in the detachable connector structure of the dull and stereotyped copper conductor of electric current, insertion rod has played the effect of conducting two ends copper coin electric currents greatly, inserts excellent material simultaneously and has selected also to have improved the body intensity that copper coin reduces because of fluting; Thereby tightening screw can ensure to insert rod and ensure good electric conductivity with fitting tightly of copper coin groove face after pretension, has also improved the physical strength of whole joint simultaneously; Expansion bolt can improve the shear strength of joint after fully expanding under the effect of pretightning force.The structure of whole joint has met the designing requirement that resistance is little, physical strength is high and do not take up space.
Brief description of the drawings
Fig. 1 is the detachable connector cut-open view of the dull and stereotyped copper conductor of a kind of large electric current provided by the present invention.
In figure, 1 copper coin, 2 copper coins, 3 insert rod, 4 expansion bolts, 5 tightening screw assemblies, 6 register pins, 7 upper padding plates, 8 lower bolsters, 9 embedding key swivel nuts, 10 stop screws.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As shown in Figure 1, the detachable connector of the dull and stereotyped copper conductor of a kind of large electric current adopts finger-type structure, mainly comprise copper coin 1, copper coin 2, insert rod 3, expansion bolt 4, tightening screw 5, register pin 6, upper padding plate 7, lower bolster 8, embedding key swivel nut 9, stop screw 10, wherein, the copper coin 1 at two ends is slotted into finger shape according to certain spacing with 2 simultaneously, in each groove, insert a Be-Co-Cu alloy rod that strength ratio copper coin is high, in the middle of every insertion rod 3, open circular hole and squeeze into register pin 6, register pin 6 is interference fit with the hole of inserting rod 3, register pin 6 matches with the semicircle orifice of joint two ends copper coin finger end face.Inserting rod 3 effect is to be equivalent to bridge beam action, and the electric current of two ends copper coin is communicated with by inserting rod 3, so select all higher Cu alloy materials of electric conductivity and physical strength.Two ends copper coin also has 2 slotted holes, inserts rod and has also opened accordingly 4 identical holes, is wherein used for installing tightening screw 5 near the hole of seam, and the hole in outside is used for installing expansion bolt 4.
In finger-type structural joint as above, the effect of tightening screw assembly 5 is by the pretightning force of bolt, copper coin finger to be fitted tightly with inserting excellent surface of contact, to ensure electric conductivity and to improve physical strength.Because this tightening screw needs very large pretightning force, in work, also can be subject to because of in coil surface, side direction electromagnetic force produce pulling force and shearing force, and the restriction of copper coin size makes that its diameter is little, length is large, so this tightening screw must use high-intensity special bolt.Tightening screw assembly 5 comprises high-intensity double threaded screw, 12 jiaos of self-locking nuts, packing ring, embedding key swivel nut 9.Embedding key swivel nut 9 is arranged in the corresponding screw of lower bolster 8, the bearing capacity being threaded for increasing the intensity that is threaded, increase screw thread stress surface, increase and fatigue resistance, shock-proof check.
In finger-type structural joint as above, the effect of expansion bolt assembly 4 is mainly the shear strength that improves joint.Expansion bolt is high-intensity special expansion bolt equally.Expansion bolt assembly 4 is made up of screw rod, some negative and positive expansion sleeves, opening long coat pipe, packing ring, 12 jiaos of self-locking nuts.The principle of work of expansion bolt is: in the time screwing nut, axial load interacts negative and positive expansion sleeve, and positive sleeve pipe radial compression is held screw rod tightly; Cloudy sleeve pipe is radially expanded and evenly struts long coat pipe, makes long coat pipe and copper coin finger and insert excellent hole to fit tightly.This expansion bolt structure can reduce even to eliminate the vibrations between joint design, improves the shear strength of joint.
In finger-type structural joint as above, upper and lower backing plate adopts stainless steel material, plays the effect of protection copper coin.The packing ring that upper padding plate 7 can protect copper coin not to be applied in larger pretightning force bolt group damages by pressure; Lower bolster is also equivalent to nutplate, so just not be used in machining screw on copper coin body, has ensured the intensity being threaded; The position that lower bolster 8 is corresponding with expansion bolt assembly 4 adds a stop screw 10, regulates the long coat pipe of expansion bolt and the degree of depth of bolt-inserting hole when expansion bolt is installed.
