Abstract
The utility model discloses a stator outlet structure of an alternating current motor. The technical scheme is that bosses (6) are arranged on a wiring board (1); grooves (7) are arranged among the bosses (6); threaded holes (8) are arranged on the grooves (7); threaded holes (9) are arranged on metal terminals (3); studs (5) are screwed into, pass through the threaded holes (9) and are screwed tightly into the threaded holes (8); flange nuts (4) are screwed onto the studs (5) and press tightly against the metal terminals (3) so as to fix the metal terminals (3) into the grooves (7); and stator coils (2) are directly fixed on the metal terminals (3). The utility model provides a novel optimized motor stator outlet structure so as to overcome shortcomings in the prior art, and therefore hidden dangers of pseudo soldering, soldering skip, creepage and the like possibly happening during the stator outlet process can be solved, and the manufacturing procedure, time and cost can be greatly reduced.
Description
Technical field
The utility model relates to field of motor manufacturing, is specifically related to a kind of stator outlet structure of alternating current machine.
Background technology
Current, the outlet structure of motor stator is generally stator line bag and is connected to patchcord and leads in the terminal box again, and stator line bag is connected by gas welding with patchcord, and this syndeton produces the hidden danger such as rosin joint, solder skip easily, affects stability and the fail safe of motor.And because this exchanging structure operation is many, man-hour is long, and the price of patchcord is higher, the labor intensive material resources, thus reduced the production efficiency of motor, increased the production cost of motor; Operation is more on the other hand, the technique hidden danger that the operation junction more might occur.Unshielded device between the binding post of conventional motors stator box, vibrations in the machine operation process, may cause terminal displacement and loosening, thereby reduce terminal pitch, creepage phenomenon between the terminal may appear, creepage result gently then burns out binding post, and is heavy then burn out whole motor, so that the serious potential safety hazard that motor exists at work.Thereby the outlet structure of conventional motors has than redesigning.
The utility model content
This practical new purpose is in order to overcome the deficiencies in the prior art, by optimizing the outlet structure of motor stator, thereby solve the rosin joint that may occur in the outlet structure of motor stator, solder skip, the hidden danger such as creepage, and greatly reduce its manufacturing process, man-hour and manufacturing cost.
In order to solve the problems of the technologies described above, the utility model adopts following technical proposals: on the terminal block of alternating-current motor stator outlet structure boss is arranged, fluted between boss, screwed hole is arranged on the groove, screwed hole is arranged on the metal terminal, and double-screw bolt screws in and passes screwed hole and be tightened in screwed hole, and flange nut is tightened on the double-screw bolt and presses metal terminal, thereby metal terminal is fixed in the groove, and stator line bag is directly fixed on the metal terminal.
Compared with prior art, the utlity model has significant advantage, be embodied as: Novel wiring board all is designed with boss and has lengthened creepage distance between the every phase of terminal, so that creepage distance is: a+2b(a is the width of boss, b is the height of boss), can reach 14-32mm, be far longer than the threshold value of creepage distance under the various conditions, and then stop creepage hidden danger.
Every phase terminal all is designed with groove and guarantees that metal terminal is firm, thereby has guaranteed that terminal wiring structure does not become flexible, is shifted because of the factors such as vibrations of motor.Metal terminal is connected line with the stator line and directly connects, rosin joint, the solder skip problem of having avoided stator line bag and patchcord welding to cause, and be connected connection and patchcord with patchcord and be connected connection with terminal owing to saved stator line bag, thereby greatly reduce operation and man-hour that motor is made, reduce the cost that motor is made, improved manufacturing efficient, manufacturing process and the quality of motor.
Compare with conventional motors stator outlet wiring construction, this kind mode of connection had both improved production efficiency on the basis of improving the quality of products, provide cost savings again, and operating procedure is simple and convenient.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further, wherein:
Fig. 1 is the attached view schematic diagram of terminal block;
Fig. 2 is the three-dimensional icon intention of terminal block;
Fig. 3 is the front view schematic diagram of terminal block;
Fig. 4 is the metal terminal schematic diagram;
Fig. 5 is the stator outlet structure schematic diagram of alternating current machine.
Embodiment
Such as Fig. 1 to Fig. 5, wherein, the 1st, terminal block, the 2nd, stator line bag, the 3rd, metal terminal, the 4th, flange nut, the 5th, double-screw bolt, the 6th, boss, the 7th, groove, the 8th, screwed hole, the 9th, screwed hole, the 10th, groove.
To shown in Figure 5, the outer wrap of stator line bag 2 has insulating material such as Fig. 1, and stator line bag 2 is directly introduced in the groove 10 of metal terminals 3 and the mode by soldering is connected and fixed, this step does not need to connect patchcord, simple to operate, save man-hour and operation, need consumptive material few.
The material of terminal block 1 is the insulation material, 4 boss 6 are arranged on the terminal block 1, between the boss fluted 7, the quantity of groove 7 is 3, screwed hole 8 is arranged on the groove 7, screwed hole 9 is arranged on the metal terminal 3, with metal terminal 3 as in the groove 7, in screwed hole 8 and screwed hole 9 on double-screw bolt 5 screw-in metal terminals 3 and the groove 7, be tightened in flange nut 4 on the double-screw bolt 5 again and press metal terminal 3, thereby metal terminal 3 is fixed in the groove 7, because the size and shape of the profile of metal terminal 3 is identical with the size and shape of groove 7, so can guarantee when motor rotation shakes, also can guarantee the not loosening and displacement of metal terminal 3.
The width a of boss 6 is 6-12mm, and the height b of boss 6 is 8-20mm, so the creepage distance of 3 of metal terminals is a+2b, is 14-32mm, creepage threshold value under the various conditions, thus stopped the creepage hidden danger of 3 of metal terminals.
