Description
Technical Field
[0001] The utility model belongs to the field of electrical technology, and relates to reactor technology, in particular to a reactor frame and a reactor. Background Art
[0002] In the home appliance industry, reactors are a key electronic component and are widely used in various electrical equipment. Reactors are mainly composed of a frame, a coil, a magnetic core, etc. The reactor frame is used to install and fix the coil and the magnetic core. Figure 2 In the existing reactor design, the coil connection point is usually located in the middle of the reactor coil. This design, on the one hand, increases the size of the reactor product in the direction of the coil connection point (i.e., the reactor height direction) by 5-10 mm, thereby increasing the overall volume of the product. On the other hand, it limits the number of coil windings. However, with the increasing requirements of the home appliance industry for product miniaturization and installation convenience, the size limitations of the existing reactor design have become increasingly prominent.
[0003] During the installation of household appliances, larger reactors tend to occupy more space, affecting the layout of other components and the aesthetics and functionality of the overall equipment. Especially in some compact household appliances, the oversized size of the reactor may cause installation difficulties or even fail to meet the customer's installation requirements. In addition, the increase in the size of the wire package connection point of the existing design may also have an adverse effect on the heat dissipation and electrical performance of the equipment.
[0004] In summary, the reactor design of the prior art requires increasing the installation space of the coil connection point because the coil connection point is located in the middle of the reactor coil, which results in a significant increase in the size of the reactor and is unable to meet the requirements of the home appliance industry for product miniaturization and installation convenience.

The three parts are combined to form an integral structure.

[0038] A groove 14 for placing the wire package connection point 3 is provided at the end of the first fixing portion 12, and wire outlet holes 15 connecting the groove 14 with the outside of the first fixing portion are provided on both sides of the groove 14; the wire outlet holes 15 include a first wire outlet hole 151 provided on the inner side of the groove and a second wire outlet hole 152 provided on the outer side of the groove, the first wire outlet hole 151 is used to place the wire package lead-out wire 4, and the second wire outlet hole 152 is used to place the wire package connection point lead-out wire 5.
[0039] The wire package connection point 3 is placed in the groove 14, and the wire package lead-out wire 4 and the wire package connection point lead-out wire 5 are effectively led out through the wire outlet holes (first wire outlet hole 151 and second wire outlet hole 152) on both sides of the groove. On the one hand, the design of the groove facilitates the installation and fixation of the wire package, and can reduce the interference between the wire package lead-out wire and the connection point lead-out wire during the wiring process, thereby improving the overall performance and reliability of the reactor skeleton. The wire package connection point can also be effectively protected. When the product is taken through the wiring harness, the design of the groove can reduce the pulling and damage to the wire package connection point and extend the service life of the product. On the other hand, placing the wire package connection point in the groove can save 5-10mm of installation space in the height direction, meeting the requirements of electrical equipment for compact design. On the other hand, since the outlet position of the wire package is at the end of the wire package, the number of turns of the wire package will not be limited.
[0040] In some embodiments, the first fixing portion 12 and the second fixing portion 13 are connected to the winding portion 14 as a whole. The three parts are combined to form an integral structure. Through this integrated design, the overall rigidity and strength of the skeleton body are improved, and the failure caused by loose components during use is effectively reduced.
[0041] In some embodiments, the groove 14 is only provided at the upper end or the lower end of the first fixing portion 12 .

By utilizing the superior magnetic permeability and structural characteristics of the E-type magnetic core, the magnetic field strength and stability of the reactor can be improved by wrapping the wire package with the magnetic core. At the same time, by inserting the two E-type magnetic cores from both ends, the installation and fixation of the magnetic core are facilitated, thereby improving the assembly efficiency and reliability of the device.

The corrosion-prone component structure (i.e., the reactor body and the connection point of the wire package) is potted in the plastic shell by potting glue for corrosion protection. Compared with the reactor using a metal shell, on the one hand, the overall weight and manufacturing cost of the reactor are reduced, and on the other hand, the corrosion resistance is enhanced, and the corrosion resistance is strong.
