Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.It is illustrative to the description only actually of at least one exemplary embodiment below, is never used as to this practicality
Novel and its application or any restrictions used.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
There is the every other embodiment obtained under the premise of making creative work, shall fall within the protection scope of the present invention.
As shown in Figures 2 and 3, a kind of electromagnetic coil for brake system of car, including shell 4, be mounted on shell 4 on
Skeleton 2, the contact pin 1 being arranged on skeleton 2 and the enameled wire 5 being wound on skeleton 2, the shell 4 include bottom wall and
Side wall surrounds accommodation space between the bottom wall and side wall, the skeleton 2 is placed in accommodation space, the side wall it is suitable for reading
Riveting is fixed with connecting plate 3.Compared with prior art, skeleton 2 and shell 4 are fixed since injection-moulded plastic 6 need not be led to, not only tied
Structure is compact, simple, improves coil production efficiency of assembling, reduces coil manufacture difficulty and cost, and improves coil and dissipate
Heat improves coil performance and reliability.
In the present embodiment, the side wall includes a pair of of riser arranged side by side vertically, breakthrough in being formed between two risers
