Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 3, the present invention provides an electromagnetic coil, comprising a stator housing 1, a stator frame 2, a coil 3 and a stator pole plate 4, the stator frameworks 2 are respectively arranged in the stator shell 1, each stator framework 2 is provided with a pin part 20, the coil 3 is wound on the stator frame 2 and connected with the pin inserting part 20, the stator pole plate 4 is arranged on the inner wall of the stator frame 2, the pin part 20 comprises a holding part 200 transitionally extending along the outer edge of the stator frame 2, fixing parts 201 respectively arranged on the holding part 200, and pins 202 arranged on the fixing parts 201, a winding space 2010 is arranged between the adjacent fixing parts 201, the holding part 200 is provided with an arc transition part 2000 at a position where the coil 3 transits along the winding space 2010, a holding block 2011 for guiding the coil 3 to be attached is further arranged between the wall surface of the fixing part 201 facing the holding part 200 and the holding part 200;
the winding space 2010 between the adjacent fixing portions 201 can reserve a space for the connection between the coil 3 and the contact pin 202, so as to guide the trend of the coil 3, so that the coil 3 can be connected with the contact pin 202 through the arc-shaped transition portion 2000 on the holding portion 200, the connection between the coil 3 and the contact pin 202 can be more attached to the holding portion 200 when passing through the arc-shaped transition portion 2000, and meanwhile, the port of the arc-shaped transition portion 2000 is provided with a step, so that the coil 3 can be effectively prevented from slipping off, and the reasonability and stability of the routing of the coil 3 are improved; the holding part 200 formed by transition along the outer edge of the stator framework 2 can support and protect the part of the enameled wire extending from the stator framework 2 to the contact pin 202, so that the enameled wire is prevented from being damaged or disconnected, and the V-shaped waterproof structures are arranged on the outer edges of the stator framework 2, so that the fusion effect of the outer edges of the stator framework 2 and the encapsulating material can be improved when the stator framework 2 is wrapped by the encapsulating material, and the sealing property of the stator framework 2 is improved; the contact pins 202 are connected with the contact pin part 20 in a positioning manner by adopting soldering, buckling or riveting and the like;
