Background technology:
Present small-sized electric car adopts two types DC motor more, and a kind of is that the brush DC motor is arranged, and another kind is a brushless DC motor.For the stator of brushless DC motor, all adopt the splicing structure of stator tooth unit to form again.Coiling separately on each stator tooth unit just behind intact line, is assembled into a circular stator again; Like this, in the groove of per two adjacent stator tooth unit, just have two the end of a thread, a first tail.If what adopt is the stator pack of 36 grooves, just have 72 end to end; These 72 end to end, and it is very difficult realizing accurately connecting, and mistake is arranged slightly, and entire product just can't run well.
Summary of the invention
In order to solve this technical barrier, the present utility model a kind of stator terminal block of small-sized DC motor of 36 grooves so that rapidly and accurately each the end of a thread in the stator winding is connected.The utility model solves this technical problem, and the technical scheme that is adopted is:
With this terminal block, make the structure of annular.On the inner periphery and excircle of terminal block, 36 slotted eyes equidistantly, are equably distributing respectively: wherein, and 101,110,119 and 128,104,113,122 and 131 in the interior slotted eye, 107,116,125 and 134, the link slot by circular arc connects respectively; In the outer slotted eye 204,207 and 210,213,216 and 219,222,225 and 228,231,234 and 201 also connected by the link slot of circular arc respectively.In 36 slotted eyes on the inner periphery, 101,110,119,128,131 and 134, be respectively long slot bore, in addition, all be short slotted eye; In 36 slotted eyes on the excircle, 201,204,207,210,213,216,219,222,225,228,231 and 234, be respectively long slot bore, in addition, all be short slotted eye.
Like this, we just can carry out the stator wiring of the small-sized DC motor of 36 grooves easily.With the end of a thread in each tooth unit winding, insert in the terminal block slotted eye that designs respectively.By the cylindrical slotted eye of terminal block, be carved with numbering, from 201 to No. 236 respectively; By the interior round slot bore of terminal block, also be carved with numbering, from 101 to No. 136 respectively.The slotted eye of excircle is to be used for the buttock line head of the coil that twines on the gear shaping unit, and the slotted eye of inner periphery is to be used for the end of a thread of the coil that twines on the gear shaping unit.We are the coil the end of a thread on the tooth unit, the head that is the end of a thread of upper end, the tail that is the end of a thread of lower end.
In the time of wiring, as long as we insert respectively in the corresponding slotted eye respectively with the head and tail of corresponding teeth unit, and then, with the arc-shaped slot of three long arc-shaped slots and four weak points, related the end of a thread links up with scolding tin again; Again adjacent 12 pairs of the end of a thread and line tail are also linked up; At last, draw three the end of a thread, link to each other with power supply respectively, whole wiring process has just been finished.
This piece terminal block has been arranged, can raise labour productivity widely, avoided mistake; Can also make the cost of product reduce 4-5%, also be convenient to realize automated production, solve the technical barrier of the stator terminal block wiring difficulty of DC motor preferably.Small-sized electric car and small generator that the utility model is specially adapted to 48V, 500W use; When having realized that material cost descends, also improved the performance of product.
