In this embodiment, the first flange portion 1 is provided with a groove 15, the groove 15 is located inside the portion where the second terminal hole 13 is located, the groove 15 penetrates through two sides of the first flange portion 1 in the thickness direction, and the hanging wire portion is located on a groove wall of the groove 15 close to the second terminal hole 13. Specifically, the groove 15 is located between the second terminal hole 13 and the third terminal hole 12. When the first flange portion includes only the first terminal hole and the second terminal hole, the groove is located between the first terminal hole and the second terminal hole.
In this embodiment, the hanging portion is an inverted boss 14, and the bottom end of the inverted boss 14 is higher than the bottom end of the groove wall where the inverted boss is located. The bottom surface 141 of the inverted boss 14 is an inclined surface, one end of the inclined surface, which is connected with the groove wall where the inverted boss 14 is located, is a high end, the other end of the inclined surface, which is far away from the groove wall where the inverted boss 14 is located, is a low end, and an included angle alpha between the inclined surface and the vertical direction is 70-80 degrees.

In this embodiment, a first wire passing notch 17 and a second wire passing notch 18 are disposed on a side surface of the first flange portion 1 facing the first wire winding portion 4, and the first wire passing notch 17 and the second wire passing notch 18 are located on two opposite sides of the first wire winding portion 4.

The coil rack convenient for automatic winding can adopt a single coil winding mode or a double coil winding mode during winding. When the single coil is wound, only the start terminal 8 and the end terminal 9 need to be respectively inserted into the terminal holes (i.e., the first terminal hole 11 and the second terminal hole 13) on both sides of the first flange portion 1, as shown in fig. 6-8, after the enameled wire 7 starts from the start terminal 8 and passes through the first wire passing gap 17 and is wound on the first wire winding portion 4, the enameled wire 7 directly enters the third wire passing gap 24 along the inclined retaining wall 25, and then the second wire winding portion 5 is wound on the second wire winding portion 72; then, the enameled wire 7 ascends from the lower end to the higher end of the groove bottom surface of the wire groove 21 inside the convex column 22, and is guided to the bottom of the inverted lug boss 14 in a straight line across the convex rib 23, and is pulled up to the terminal 9 after being hung on the inverted lug boss 14, and the terminal 9 is clockwise wound by 2-3 turns to complete the single-coil winding.
When the double coils are wound, in addition to the starting terminal 8 and the ending terminal 9 respectively inserted into the terminal holes at the two sides (i.e., the first terminal hole 11 and the second terminal hole 13), the common terminal 10 is inserted into the terminal hole at the middle (i.e., the third terminal hole 12), as shown in fig. 9-13, the enameled wire 7 starts from the starting terminal 8, passes through the first wire passing notch 17, completes the winding of the first group of coils 71 in the first winding part 4, returns to the common terminal 10, returns to the first winding part 4 along the second wire passing notch 18 after the common terminal 10 is wound for 2-3 turns, enters the third wire passing notch 24 along the inclined retaining wall 25 after being wound for several turns at a large interval, and then completes the winding of the second group of coils 72 in the second winding part 5; then, the enameled wire 7 rises from the lower end to the higher end of the bottom surface of the wire groove 21 inside the convex column 22, and is guided to the bottom of the inverted boss 14 by crossing the convex rib 23, and is pulled up to the terminal 9 after being hung on the inverted boss 14, and the terminal 9 is clockwise wound by 2-3 turns to complete the winding of the double coils.
Regardless of the winding manner of the single coil or the double coils, the top end of the protruding rib 23 is higher than the height of the first group of coils 71, so that the lapped enameled wires 73 and the enameled wires of the first group of coils 71 can be prevented from being lapped and touched together, as shown in fig. 14, and therefore, when the coils are powered off, reverse voltage breakdown at the lapped parts (when the start and end lines are lapped together, a voltage difference is easily formed), and coil short circuit is caused, so that the function of the relay is lost.
According to the coil rack convenient for automatic winding, the first wire part is adopted to replace a bridging terminal, so that an enameled wire is prevented from being wound manually, and meanwhile, the wire hanging part is adopted to hang a wire, so that the height of the tail end line part (namely the spanned enameled wire 73) of the enameled wire between the first flange part and the second flange part is reduced, and therefore a wire pressing mechanism is not adopted to press the wire. According to the invention, through the design of the coil frame structure, the potential failure risk in the winding process can be reduced, better guidance can be provided for fixing and limiting the enameled wire 7, and the automatic winding is convenient to realize.
Referring to fig. 1 to 14, a coil of the present invention includes an enameled wire 7 and a plurality of terminals, which specifically include a start terminal 8, a common terminal 10, and an end terminal 9. The coil of the present invention further includes the coil frame for facilitating automatic winding according to the present invention, the common terminal 10 may be selectively inserted into the middle terminal hole (i.e., the third terminal hole 12), the start terminal 8 and the end terminal 9 are respectively inserted into the other two terminal holes (i.e., the first terminal hole 11 and the second terminal hole 13), the enamel wire 7 is led from the start terminal 8 to the hanging part through the wire groove 21 after being wound in the single coil winding manner or the double coil winding manner, and is connected to the end terminal 9 after being hung at the hanging part. The common terminal 10 can be selectively inserted into the middle terminal hole 12, which means that when the single coil winding mode is adopted, only the terminal holes 11 and 13 at two sides of the first flange part 1 are respectively inserted with the initial terminal 8 and the terminal 9, and the middle terminal hole 12 is not required to be inserted with the common terminal 10; when the double coil winding method is adopted, the three terminals 11, 12, 13 of the first flange portion 1 correspond to the insertion start terminal 8, the common terminal 10, and the end terminal 9, respectively.
The coil of the present invention may adopt a single coil winding manner or a double coil winding manner, and the two coil winding manners are as described above and will not be described herein again. When the plurality of terminal holes of the first flange portion include the first terminal hole and the second terminal hole and do not include the third terminal hole, the plurality of terminals include only the start terminal and the end terminal and do not include the common terminal, and at this time, the present invention may employ only a single coil winding manner.
A magnetic latching relay of the present invention includes the coil according to the present invention described above.
The parts which are not involved in the magnetic latching relay are the same as or can be realized by the prior art.
The above embodiments are merely provided to further illustrate the coil bobbin and the coil and the magnetic latching relay of the present invention for facilitating automatic winding, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the scope of the technical solution of the present invention.
