Description

Technical Field

[0001] The utility model relates to the field of induction cookers, in particular to a power line connection structure and an induction cooker. Background Art

[0002] Currently, the power cord of the induction cooker is connected from the inside of the induction cooker shell to the outside of the induction cooker to connect to the mains. Therefore, an opening adapted to the size of the power cord is usually required on the shell of the induction cooker. The shell of the induction cooker usually includes an upper shell and a lower shell, which can be locked together by screws, and the space between the upper shell and the lower shell is used to install the electrical components of the induction cooker. Since the two ends of the power cord are usually connectors, half an opening is usually opened on the upper shell and the lower shell so that the middle section of the power cord is placed in the two openings. However, this installation method requires accurate openings on the upper shell and the lower shell. Once there is a deviation in the opening, it may cause the power cord to be unable to be routed or the upper shell and the lower shell to be unable to be closed. Utility Model Content

[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for use in the description of the embodiments. Obviously, the drawings described are only part of the embodiments of the present invention, not all of them. Those skilled in the art can also obtain other design solutions and drawings based on these drawings without creative work.

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0023] Reference Figure 1 to Figure 6 A power cord connection structure comprises a power cord main body 1, characterized in that the power cord connection structure further includes an upper shell 2 and a lower shell 3, a clamping portion is provided on the wiring head of the power cord main body 1, the upper shell 2 is provided with a plug-in portion, and a threading hole is opened on the lower shell 3, the threading hole is located in the middle of the side of the lower shell, the wiring head of the power cord main body 1 is inserted into the lower shell from the threading hole, the upper shell 2 and the lower shell 3 are buckled up and down, and the plug-in portion is inserted into the clamping portion to limit the movement of the power cord main body 1 along the depth direction of the threading hole.

[0024] As can be seen from the above, the structure not only includes the power cord body 1, but also is equipped with the upper and lower parts of the upper shell 2 and the lower shell 3. The safety and stability of the power cord can be improved. One of the core parts of the power cord connection structure includes the power cord body 1. It is responsible for transmitting power, for example, it can be connected to the mains and the induction cooker, and the mains provides power to the induction cooker. In addition, a clamping part is also provided on the wiring head of the power cord body 1 to facilitate connection with other components. The upper shell 2 and the lower shell can protect the power cord body 1 from damage by the external environment. The upper shell 2 is provided with a plug-in part, which is convenient for connecting with the clamping part of the power cord body 1; this design makes the power cord connection more stable. At the same time, different from the way in which the power cord is clamped by openings between the upper shell 2 and the lower shell 3 in the prior art, the aperture of the first wire hole 31 opened on the lower shell 3 in the utility model is larger than the outer diameter of the power cord body 1, so that the power cord body 1 can directly pass through or pass through the first wire hole 31. The threading hole is located in the middle of the side of the lower shell, which is conducive to the smooth insertion of the terminal of the power cord body 1, and at the same time, it is prevented from extending the threading hole to the edge of the lower shell 3 to affect the strength of the lower shell 3. In actual use, the plug-in part is inserted into the clamping part, which effectively limits the movement of the power cord body 1 along the depth direction of the threading hole. This design makes the power cord connection more stable and makes the assembly of the induction cooker very convenient.

[0025] In some embodiments, a groove 12 is provided at the joint of the power cord body 1, and the groove 12 is the clamping portion, and the clamping portion is clamped and matched with the groove 12. In order to ensure the stability of the power cord, a groove 12 is specially provided at the joint. This groove 12 is the clamping portion, which plays a connecting role. The cooperation between the groove 12 and the clamping portion is mutually adapted. When the clamping portion is inserted into the card slot, the power cord body 1 can be restricted from moving along the depth direction of the first wire hole 31.

[0026] In some embodiments, grooves 12 are respectively provided on the left and right sides of the wiring head of the power cord body 1, and the grooves 12 extend upward to the top surface of the wiring head of the power cord, and the clamping part is inserted into the grooves 12. The structure is simple and convenient to set, and the grooves 12 are set on the left and right sides of the wiring head, and the plug-in part is inserted into the grooves 12. In this way, the connection between the plug-in part and the two grooves 12 is stable and the force is evenly applied.

[0027] In some embodiments, the plug-in part includes a pressing block 23, a first clamping block 21 and a second clamping block 22. The pressing block 23 is fixed on the upper housing 2. The first clamping block 21 and the second clamping block 22 are respectively fixed on the pressing block 23. The first clamping block 21 and the second clamping block 22 are arranged at intervals. The pressing block 23 is used to press down the top surface of the connection head of the power cord body 1. The first clamping block 21 and the second clamping block 22 are respectively inserted into the grooves 12 on the left and right side surfaces of the connection head of the power cord body 1. The plug-in part is used to be inserted into the two grooves 12. During use, the first clamping block 21 and the second clamping block 22 are respectively inserted into the two grooves 12 one by one to achieve the clamping function. In addition, the pressing block 23 between the first clamping block 21 and the second clamping block can be used to limit the connection head of the power cord body 1 downward, and its structure is stable.

[0028] In some embodiments, the power connection structure further includes a limiting plate 4. The limiting plate 4 is arranged in a U shape. The U-shaped opening of the limiting plate 4 faces the first wire passing hole 31 on the lower housing. The limiting plate 4 is arranged in the lower housing 3. The limiting plate 4 is fixed on the lower housing 3. A second wire passing hole 41 is provided in the middle of the limiting plate 4. The second wire passing hole 41 is aligned with the first wire passing hole 31. The connection head of the power cord body 1 passes through the second wire passing hole 41. During use, the lower sides of the first wire passing hole 31 and the second wire passing hole 41 can be used to support the power cord body 1 upward, and its support structure is stable. At the same time, the first wire passing hole 31 and the second wire passing hole 41 can play a certain role in radially limiting the power cord body 1 so as to preliminarily position the power cord body 1.

[0029] In some embodiments, a limiting space is formed between the U-shaped limiting plate 4 and the lower housing 3. The clamping part is located in the limiting space. This structure is simple and convenient to set. In actual use, the limiting space can be used to preliminarily limit the clamping part.

[0030] In some embodiments, a limiting step 11 is provided on the power cord body 1. The limiting step 11 is arranged outside the lower housing 3. The width of the limiting step 11 is greater than the width of the first wire passing hole 31. This structure is simple and convenient to set. By setting the limiting step 11, the depth of the power cord body 1 inserted into the first wire passing hole 31 can be effectively limited, so as to quickly position and facilitate the assembly of the induction cooker.

[0031] The present utility model also provides an induction cooker, which includes the power cord connection structure in any of the above embodiments.
