Description

Technical Field

[0001] The utility model discloses an electromagnetic heating device, belonging to the technical field of electromagnetic heating devices. Background Art

[0002] With the development and popularization of the small household appliance industry, electromagnetic heating devices are deeply loved by consumers due to their advantages such as easy portability and fast heating. The existing electromagnetic heating devices include a base and a panel assembly. An electromagnetic coil disc, a main control board and a fan are arranged inside the base. After the electromagnetic coil disc is powered on, heat is generated, and then a heating area is formed on the panel assembly to realize the heating of cookware. The main control board controls the operation of the electromagnetic coil disc to achieve different cooking effects. The fan can play a role in dissipating heat from the main control board, slowing down the heating rate of the main control board and preventing the main control board from operating at a high temperature for a long time.

[0003] In the prior art, air inlet holes are provided on the bottom wall or side wall of the base. The fan guides the external air flow to enter the inside of the base from the air inlet holes and blows the air flow towards the main control board to cool the main control board. The electromagnetic heating device usually further includes a display board and a wind shield. The wind shield is installed above the fan and is used to guide the air flow formed by the fan towards the main control board. An installation groove for installing the display board is provided on the wind shield, and the bottom surface of the installation groove is provided with an opening for cooperating with the positioning posts inside the base to realize the installation and positioning of the wind shield and the base.

[0004] However, during the assembly process, the installation of the wind shield and the display board usually requires first using a plurality of fasteners to fix the wind shield on the base, and then installing the display board into the installation groove. This assembly process is relatively cumbersome and affects the assembly efficiency. In addition, the display board covers the fasteners, and the tightness of the fasteners may cause the installation of the display board to be uneven, affecting the display effect of the display board. Secondly, during daily use, the fan is likely to suck external pollutants such as oil stains and water vapor into the base, and there is a possibility that the pollutants enter the lower surface of the display board from the opening and contaminate the display board, further affecting the display effect of the display board. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems that the installation of the existing wind shield is relatively cumbersome and easily affects the display effect of the display board. Therefore, an electromagnetic heating device is provided, which can reduce the installation difficulty of the wind shield and reduce the possibility of the display board being contaminated.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An electromagnetic heating device includes a base, a heat dissipation device located inside the base, a main control board, and a wind shield. A display board is installed on the wind shield. A partition is provided inside the base, and the partition divides the interior of the base into a first area and a second area. The heat dissipation device and the main control board are located in the first area. The wind shield is placed on the partition and covers the heat dissipation device and the main control board. The bottom of the wind shield is provided with a limiting rib that is in limiting cooperation with the partition, and a positioning rib that is in limiting cooperation with the side wall of the wind shield is provided in the second area. The positioning rib and the partition form a circumferential limit for the wind shield.

[0008] The beneficial effects of adopting the utility model are as follows:

[0009] In the utility model, the partition can serve as a windbreak wall to gather the air flow formed by the heat dissipation device in the first area and prevent the air flow from blowing into the second area. The wind shield is placed on the partition and covers the heat dissipation device and the main control board. The cooperation between the wind shield and the partition can guide the air flow to the main control board, thereby accelerating the air flow in the area where the main control board is located, facilitating the timely removal of the heat of the main control board by the air flow, slowing down the temperature rise rate of the main control board, effectively avoiding the main control board being in a high-temperature state for a long time, and reducing the possibility of damage to the main control board due to high-temperature operation; in addition, the limiting rib at the bottom of the wind shield is in limiting cooperation with the partition, and the positioning rib is in limiting cooperation with the side wall of the wind shield. The circumferential positioning of the wind shield can be achieved through the partition and the positioning rib, without the need to open holes on the wind shield and use fasteners to fix the wind shield, thereby maintaining the integrity of the wind shield, enabling the wind shield to separate the heat dissipation device from the display board, effectively reducing the possibility of the lower surface of the display board being contaminated by pollutants, enabling the display board to maintain a good display effect, and at the same time avoiding failures such as rust or short circuit of the display board due to pollutants; secondly, during the assembly process of the wind shield, the display board can be assembled with the wind shield in advance, and then the display board is placed inside the base, and the wind shield is positioned by the partition and the positioning rib, which can make the assembly process of the wind shield simpler and faster, helping to improve the installation efficiency of the wind shield; in addition, the omission of the use of fasteners can make the assembly of the display board and the wind shield more tightly and reliably, enable the display board to remain flat, improve the display effect of the display board, and help to enhance the user experience.

[0010] Preferably, the limiting ribs are strip-shaped and extend along the length direction of the partition board; alternatively, the windshield is provided with a plurality of limiting ribs that are spaced apart along the length direction of the partition board. With the foregoing technical solution, the strip-shaped limiting ribs can increase the contact area between the limiting ribs and the partition board, making the limiting fit between the limiting ribs and the partition board more stable and reliable. At the same time, it can also increase the strength of the limiting ribs themselves, reduce the possibility of the limiting ribs breaking, and help extend the service life of the limiting ribs; or the spaced-apart distribution of the limiting ribs can provide sufficient laying space for the reinforcing ribs, avoid interference between the limiting ribs and the reinforcing ribs, and enable the partition board to be equipped with longer reinforcing ribs to enhance the strength of the partition board.

The first limiting portion is fixed to the bottom of the windshield and extends along the length direction of the partition board, and the second limiting portion is fixed to the bottom of the first limiting portion and extends downward.

With the foregoing technical solution, the first limiting portion can increase the contact area in the length direction of the partition board, thereby reducing the swaying amplitude of the windshield on the horizontal plane. The second limiting portion can increase the contact area in the height direction of the partition board, thereby reducing the swaying amplitude of the windshield on the vertical plane, further improving the limiting stability between the limiting rib and the partition board, helping to reduce the swaying amplitude of the windshield, and making the positioning of the windshield more stable and reliable; in addition, the cooperation between the first limiting portion and the second limiting portion can effectively strengthen the overall strength of the limiting rib and reduce the possibility of the limiting rib breaking.

[0012] Preferably, a plurality of reinforcing ribs are spaced apart on the surface of the partition board, and the windshield is placed on the partition board so that the first limiting portion is on the upper side of the reinforcing rib and the second limiting portion is between two adjacent reinforcing ribs. With the foregoing technical solution, the reinforcing ribs can enhance the overall strength of the partition board, effectively reduce the possibility of the partition board deforming or breaking, and keep the cooperation between the partition board and the limiting rib stable and reliable; in addition, the first limiting portion is on the upper side of the reinforcing rib, which can prevent interference between the first limiting portion and the reinforcing rib while maintaining the overall length of the first limiting portion. Similarly, the second limiting portion is between two adjacent reinforcing ribs, which can also prevent interference between the second limiting portion and the reinforcing rib, so that the second limiting portion has sufficient length in the height direction of the partition board to maintain the stable cooperation between the limiting rib and the partition board.

[0014] Preferably, the heat dissipation device includes a fan and a baffle plate located on the outer peripheral side of the fan, the wind shield plate covers the baffle plate, and the wind shield plate is provided with a downwardly extending baffle rib, and the baffle rib is located on the outer side of the baffle plate. By adopting the above-mentioned technical solution, the baffle rib extends downward from the upper side of the baffle plate to the outer side of the baffle plate, which can reduce the loss of airflow between the baffle rib and the baffle plate, improve the airflow tightness between the baffle rib and the baffle plate, and enable more airflow to flow to the main control board, which helps to improve the wind gathering effect of the wind shield, and also can improve the heat dissipation effect of the main control board; in addition, the limiting cooperation between the baffle rib and the baffle plate can also play a guiding role in the installation of the wind shield, further reducing the difficulty of installing the wind shield, and can also play a positioning role in the wind shield, and improve the positioning stability of the wind shield.

[0015] Preferably, the partition is provided with a wire clamping slot for the wire to pass through, the slot of the wire clamping slot extends to the top of the partition, and the wind shield is placed on the partition and closes the slot. With the above technical solution, the wire clamping slot can play a role in gathering the wires, making the laying of the wires more neat, and can also reduce the swing amplitude of the wires to avoid mutual entanglement between multiple wires; in addition, the slot of the wire clamping slot extends to the top of the partition, so that the wires can be inserted into the wire clamping slot from the top of the partition, thereby facilitating the installation of the wires; secondly, the wind shield closes the slot, which can limit the wires from leaving the wire clamping slot, making the fixation of the wires more stable and reliable.

[0016] Preferably, the windshield includes a first side wall, a second side wall and a third side wall. The windshield has a longitudinal direction and a transverse direction.

[0035] In the present utility model, unless otherwise clearly specified and defined, terms such as "mounted", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] As Figures 1 to 10 shown, this embodiment shows an electromagnetic heating device, including a base 1, a panel assembly 2, a heat dissipation device 13, a main control board 14, a wind shield 3, and an electromagnetic coil disk 11 disposed inside the base 1. The electromagnetic coil disk 11 is electrically connected to a power cord 111. A display board 4 is mounted on the wind shield 3. After the power cord 111 is connected to the power supply, the electromagnetic coil disk 11 is controlled by the main control board 14 to perform heating, and then a heating area is formed on the panel assembly 2 to achieve cooking of cookware. The display board 4 forms a display area on the panel assembly 2 and is used to display the operating state of the electromagnetic heating device, so that users can intuitively understand the operation of the electromagnetic heating device. During the cooking process, the main control board 14 generates heat during its own operation, and at the same time, the heat generated by the electromagnetic coil disk 11 also affects the temperature around the main control board 14. In order to prevent the main control board 14 from operating overheated for a long time, the fan in the heat dissipation device 13 rotates to direct the airflow formed by the fan towards the main control board 14 to dissipate heat from the main control board 14.

[0037] As Figures 1 to 4 shown, in this embodiment, a partition 12 is provided inside the base 1. The partition 12 divides the interior of the base 1 into a first area 151 and a second area 152. The heat dissipation device 13 and the main control board 14 are disposed in the first area 151. The wind shield 3 is placed on the partition 12 and covers the heat dissipation device 13 and the main control board 14. A limiting rib 33 for limiting cooperation with the partition 12 is provided at the bottom of the wind shield 3. A positioning rib 16 for limiting cooperation with the side wall of the wind shield 3 is provided in the second area 152. The positioning rib 16 and the partition 12 form circumferential limitation on the wind shield 3.

[0038] In this embodiment, the partition 12 can serve as a windbreak wall to gather the air flow formed by the heat dissipation device 13 within the first area 151 and prevent the air flow from blowing into the second area 152. The windshield 3 is placed on the partition 12 and covers the heat dissipation device 13 and the main control board 14. The cooperation between the windshield 3 and the partition 12 can guide the air flow to the main control board 14, thereby accelerating the air flow in the area where the main control board 14 is located, facilitating the timely removal of the heat of the main control board 14 by the air flow, slowing down the heating rate of the main control board 14, effectively avoiding the main control board 14 being in a high-temperature state for a long time, and reducing the possibility of damage to the main control board 14 due to high-temperature operation. Additionally, the limiting ribs 33 at the bottom of the windshield 3 are in limiting cooperation with the partition 12, and the positioning ribs 16 are in limiting cooperation with the side wall of the windshield 3. The circumferential positioning of the windshield 3 can be achieved through the partition 12 and the positioning ribs 16 without opening holes on the windshield 3 and using fasteners to fix the windshield 3. Furthermore, the integrity of the windshield 3 can be maintained, enabling the windshield 3 to separate the heat dissipation device 13 from the display board 4, effectively reducing the possibility of the lower surface of the display board 4 being contaminated by pollutants, enabling the display board 4 to maintain a good display effect, and at the same time avoiding failures such as corrosion or short circuit of the display board 4 due to pollutants. Secondly, during the assembly process of the windshield 3, the display board 4 and the windshield 3 can be assembled in advance, and then the display board 4 is placed in the base 1 and positioned through the partition 12 and the positioning ribs 16, which can make the assembly process of the windshield 3 simpler and faster, helping to improve the installation efficiency of the windshield 3. Additionally, the omission of the use of fasteners can make the assembly of the display board 4 and the windshield 3 more tightly and reliably, enabling the display board 4 to remain flat, improving the display effect of the display board 4, and helping to enhance the user experience.

[0039] As Figure 1 and Figure 2 shown, in this embodiment, the base 1 includes a front side wall and a rear side wall. It should be noted that during normal use, the front side wall of the electromagnetic heating device is close to the user, and the rear side wall is far from the user. Inside the base 1, the electromagnetic coil disk 11 is close to the rear side wall, and the partition 12 is close to the front side wall. A first area 151 is formed between the partition 12 and the rear side wall, and a second area 152 is formed between the partition 12 and the front side wall. Moreover, the volume of the first area 151 is much larger than that of the second area 152. The display board 4 is installed on the side of the windshield 3 close to the front side wall. The heat dissipation device 13 and the main control board 14 are arranged in the first area 151 and close to the partition 12. After the heat dissipation device 13 forms an air flow, the partition 12 can block the air flow and prevent it from entering the second area 152. At the same time, the heat dissipation device 13 is arranged close to the partition 12, which can also timely gather and guide the air flow, accelerating the air flow to the main control board 14, so that the air flow can still maintain a relatively fast flow rate when it reaches the main control board 14, helping to improve the heat dissipation effect of the main control board 14.

[0040] As Figure 3and Figure 9 As shown in Figure 9 , in this embodiment, the windshield 3 includes a first side wall 311, a second side wall 312, and a third side wall 313. The windshield 3 has a longitudinal direction and a transverse direction. The first side wall 311 and the second side wall 312 are arranged opposite to each other in the transverse direction. The third side wall 313 and the limiting rib 33 are arranged opposite to each other in the longitudinal direction. The positioning rib 16 is located on the side of the second area 152 close to the front side wall. The positioning rib 16 includes a first positioning rib 161, a second positioning rib 162, and a third positioning rib 163. The first positioning rib 161 and the second positioning rib 162 form a transverse limit for the windshield 3. The third positioning rib 163 and the partition 12 form a longitudinal limit for the windshield 3. The first positioning rib 161 and the second positioning rib 162 are respectively in limiting cooperation with the first side wall 311 and the second side wall 312 to realize the transverse limit of the windshield 3. The third positioning rib 163 and the partition 12 are respectively in limiting cooperation with the third side wall 313 and the limiting rib 33 to realize the longitudinal limit of the windshield 3, so as to realize the positioning of the windshield 3, so that the installation of the windshield 3 does not require the use of fasteners, reducing the installation difficulty of the windshield 3; in addition, by placing the positioning rib 16 close to the front side wall of the base 1, the distance between the positioning rib 16 and the partition 12 can be increased, thereby increasing the length of the windshield 3 restricted in the longitudinal direction and making the positioning of the windshield 3 more stable and reliable.

[0041] As Figure 3 , Figure 8 and Figure 9 As shown in Figure 3 , Figure 8 , and Figure 9 , in this embodiment, when the windshield 3 is positioned on the partition 12, the limiting rib 33 is located in the second area 152. The positioning rib 16 has a supporting portion 165 and a stepped portion 164. The supporting portion 165 abuts against the bottom of the windshield 3 and forms a support for the windshield 3. The stepped portion 164 extends upward and is located outside the side wall of the windshield 3. The stepped portions 164 of the first positioning rib 161 and the second positioning rib 162 are respectively located outside the first side wall 311 and the second side wall 312, that is, the first side wall 311 and the second side wall 312 are located between the stepped portions 164 of the first positioning rib 161 and the second positioning rib 162, thereby realizing the transverse limit of the windshield 3; the stepped portion 164 of the third positioning rib 163 is located outside the third side wall 313, that is, the third side wall 313 and the limiting rib 33 are located between the stepped portion 164 of the third positioning rib 163 and the partition 12, thereby realizing the longitudinal limit of the windshield 3; in addition, the cooperation between the supporting portion 165 and the partition 12 can form a support for the installation of the windshield 3, making the installation of the windshield 3 more stable and improving the positioning stability of the windshield 3.

[0042] It should be noted that in this embodiment, the positioning rib 16 includes a first positioning rib 161, a second positioning rib 162, and a plurality of third positioning ribs 163. Among them, the third positioning rib 163 is fixed to the front side wall of the base 1, and the third positioning rib 163 is connected to the front side wall, which can enhance the strength of the third positioning rib 163 and reduce the possibility of deformation or fracture of the third positioning rib 163 due to excessive force, so that the positioning of the windshield 3 can be kept stable and reliable. In addition, since the windshield 3 has a relatively large length in the horizontal direction, by providing a plurality of third positioning ribs 163, the force on the windshield 3 can be made more uniform, and at the same time, the pressure on a single third positioning rib 163 can also be reduced, further reducing the possibility of deformation or fracture of the third positioning rib 163.

[0043] Of course, it can be understood that in other embodiments, the first positioning rib 161 and the second positioning rib 162 can also cooperate with the partition plate 12 to form longitudinal limitation on the windshield 3. In this embodiment, the first positioning rib 161 and the second positioning rib 162 can be provided with positioning parts, and the positioning parts extend upward from the supporting part 165 and are located outside the third side wall 313, that is, the third side wall 313 and the limiting member are located between the partition plate 12 and the positioning parts, so as to form longitudinal limitation on the windshield 3.

[0044] Of course, it can be understood that in other embodiments, when the windshield 3 is positioned on the partition plate 12, the limiting rib 33 can also be located on the side of the partition plate 12 away from the second area 152. The third side wall 313 has an extending part extending downward, and the third positioning rib 163 is located on the side of the extending part facing the limiting rib 33, that is, the partition plate 12 and the third positioning rib 163 are located between the limiting rib 33 and the extending part, so as to form longitudinal limitation on the windshield 3.

[0045] As Figures 5 to 10 shown, in this embodiment, the windshield 3 includes a windshield plate 32 and a mounting base 31. Among them, the upper surface of the mounting base 31 is provided with a mounting groove 34 for mounting the display board 4. The windshield plate 32 covers the upper sides of the heat dissipation device 13 and the main control board 14. The mounting groove 34 can position the display board 4. At the same time, there are no openings and fasteners in the mounting groove 34, which can make the installation of the limiting plate more stable and flat, enable the display board 4 to show a better display effect, and contribute to improving the aesthetic degree of the electromagnetic heating device. In addition, the windshield plate 32 can form a windbreak wall on the top of the heat dissipation device 13 and guide the air flow to the main control board 14, so that the air flow can directly and quickly flow to the main control board 14, facilitating the effective heat dissipation of the main control board 14 and contributing to improving the heat dissipation effect of the main control board 14.

[0046] In addition, the heat dissipation device 13 includes a fan and a baffle 131 on the outer peripheral side of the fan. The wind deflector 32 covers the baffle 131, and the wind deflector 32 is provided with a downward-extending rib 35. The rib 35 is located outside the baffle 131 and extends downward from the upper side of the baffle 131 to the outside of the baffle 131, which can reduce the loss of air flow between the rib 35 and the baffle 131, improve the airtightness of the air flow between the rib 35 and the baffle 131, enable more air flow to flow to the main control board 14, contribute to improving the air gathering effect of the wind deflector 3, and at the same time can also improve the heat dissipation effect of the main control board 14. In addition, the limiting cooperation between the rib 35 and the baffle 131 can also play a guiding role in the installation of the wind deflector 3, further reducing the installation difficulty of the wind deflector 3, and at the same time can also play a positioning role for the wind deflector 3, improving the positioning stability of the wind deflector 3. It should be noted that, in order to improve the wind blocking effect of the partition 12 and the baffle 131, the partition 12 and the baffle 131 in this embodiment are of an integral structure.

[0047] As Figure 3 , Figure 4 and Figure 10 shown, in this embodiment, the limiting rib 33 includes a first limiting portion 331 and a second limiting portion 332. The first limiting portion 331 is fixed to the bottom of the wind deflector 3 and extends along the length direction of the partition 12. The second limiting portion 332 is fixed to the bottom of the first limiting portion 331 and extends downward. Both the first limiting portion 331 and the second limiting portion 332 are in limiting cooperation with the partition 12. Among them, the limiting rib 33 includes two second limiting portions 332, and the two second limiting portions 332 are spaced apart from each other at the bottom end of the first limiting portion 331. A plurality of reinforcing ribs 121 are spaced apart from each other on the surface of the partition 12, and the reinforcing ribs 121 extend from the bottom of the base 1 towards the top of the partition 12. The length of the reinforcing ribs 121 is less than the height of the partition 12. When the wind deflector 3 is placed on the partition 12, the first limiting portion 331 is located above the reinforcing ribs 121, and the second limiting portion 332 is located between two adjacent reinforcing ribs 121.

[0048] In this embodiment, the first limiting portion 331 can increase the contact area in the length direction of the partition 12, thereby reducing the swaying amplitude of the wind deflector 3 on the horizontal plane. The second limiting portion 332 can increase the contact area in the height direction of the partition 12, thereby reducing the swaying amplitude of the wind deflector 3 on the vertical plane, further improving the limiting stability between the limiting rib 33 and the partition 12, contributing to reducing the swaying amplitude of the wind deflector 3, and making the positioning of the wind deflector 3 more stable and reliable. In addition, the cooperation between the first limiting portion 331 and the second limiting portion 332 can effectively strengthen the overall strength of the limiting rib 33 and reduce the possibility of the limiting rib 33 breaking.

[0049] In addition, a region for abutting against the first limiting portion 331 is formed between the top end of the partition plate 12 and the reinforcing rib 121. Therefore, while maintaining the overall length of the first limiting portion 331, it is also possible to prevent interference between the first limiting portion 331 and the reinforcing rib 121. Similarly, the reinforcing ribs 121 are arranged at intervals, and the space between two adjacent reinforcing ribs 121 allows the second limiting portion 332 to extend therein, which can also prevent interference between the second limiting portion 332 and the reinforcing rib 121. Furthermore, the second limiting portion 332 has sufficient length in the height direction of the partition plate 12 to maintain the stable cooperation between the limiting rib 33 and the partition plate 12. Secondly, the reinforcing rib 121 can enhance the overall strength of the partition plate 12, effectively reducing the possibility of deformation or fracture of the partition plate 12, and keeping the cooperation between the partition plate 12 and the limiting rib 33 stable and reliable. It should be noted that the number of the second limiting ribs 33 can also be set to one only, or the number of the second limiting ribs 33 can also be more than two.

[0050] Of course, it can be understood that in other embodiments, the limiting rib 33 can also only include the first limiting portion 331, that is, the limiting rib 33 is strip-shaped and extends along the length direction of the partition plate 12; or the limiting rib 33 can also only include the second limiting portion 332. The windshield 3 is provided with a plurality of limiting ribs 33, and the limiting ribs 33 are distributed at intervals along the length direction of the partition plate 12.

[0051] It should be noted that, as Figure 7 shown, in this embodiment, the reinforcing rib 121 is arranged on the side of the partition plate 12 in the second area 152. When the partition plate 12 has sufficient strength, there is no need to arrange a reinforcing rib 121 on the side of the reinforcing rib 121 in the first area 151, so that the side of the reinforcing rib 121 in the first area 151 can be kept smooth and flat, facilitating the heat dissipation device 13 and the main control board 14 to be as close as possible to the partition plate 12. The partition plate 12 aggregates the airflow and timely guides the airflow to the main control board 14, so that the airflow flowing to the main control board 14 maintains a relatively high flow rate, thereby improving the heat dissipation effect of the airflow on the main control board 14.

[0052] As Figure 7 and Figure 8As shown, the partition 12 in this embodiment is provided with a wire clamping groove 122 for the wire to pass through, and the wire clamping groove 122 is located on the side of the partition 12 close to the main control board 14, so that the wire can be directly connected to the main control board 14 after passing through the wire clamping groove 122. The notch of the wire clamping groove 122 extends to the top of the partition 12, and the top of the partition 12 is provided with a protrusion 123, and the protrusion 123 is located on one side of the notch. When the windshield 3 is placed on the partition 12, the partition 12 supports the windshield 3, and at the same time, the partition 12 covers the notch and closes the notch, and the protrusion 123 is located on the second side. On the outside of the wall 312, the protrusion 123 can form a lateral limit for the wind shield 3, and the wire clamping groove 122 can gather the wires, making the laying of the wires more orderly, and at the same time can reduce the swing amplitude of the wires to avoid mutual entanglement between multiple wires; in addition, the notch of the wire clamping groove 122 extends to the top of the partition 12, so that the wire can be inserted into the wire clamping groove 122 from the top of the partition 12, thereby facilitating the installation of the wire; secondly, the wind shield 3 forms a closure on the notch, which can limit the wire from escaping from the wire clamping groove 122, making the fixation of the wire more stable and reliable.

Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
