Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic component support technology, specifically an integrated connection structure between an electric rice cooker NTC and a fuse. Background Technology
[0002] In a rice cooker, an NTC (Non-Temperature Coefficient) is a thermistor whose resistance decreases as the temperature rises, exhibiting a negative temperature coefficient. It is used to monitor the temperature changes of the inner pot in real time. When the temperature reaches the set value (such as during the rice boiling or keep-warm stage), the control system adjusts the heating power based on the resistance value fed back by the NTC. A rice cooker fuse is a protective electrical appliance that breaks the circuit by melting the fusible element when the current exceeds a specified value, using the heat generated by the fuse itself.
[0003] In the actual installation of electronic components NTC and fuses, customized brackets are required for support to ensure proper connection with the circuit board and to achieve the desired working effect. However, because NTC and fuse require two different connection brackets for positioning and lack universality, the actual production cost is high. If a universal bracket could be combined, certain costs could be saved. Therefore, this application provides an integrated connection structure for rice cooker NTC and fuse to solve the above problems. Utility Model Content

This solves the problem that existing connection structures for NTC and fuses are all separate brackets and lack versatility, resulting in high actual costs.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: an integrated connection structure for an electric rice cooker NTC and a fuse, including a main support plate 1, a fuse element body 10, and an NTC element body 11. The top of the main support plate 1 has four first limiting holes 2 and one second limiting hole 4. A limiting piece 6 is fixed to the bottom of the main support plate 1, and an arc-shaped limiting plate 7 is fixed to one side of the back of the limiting piece 6. A connecting plate 8 is fixed to the top of the main support plate 1, and a limiting member 9 for limiting the outer side of the NTC element body 11 is fixed to the top of the connecting plate 8. Through the cooperation of the main support plate 1, the first limiting holes 2, the second limiting holes 4, the arc-shaped limiting plate 7, and the limiting member 9, the NTC and the fuse can be connected and supported simultaneously, making it versatile. Only one connecting bracket is needed to complete the connection of two brackets, saving actual production costs. At the same time, it can also have a certain limiting function, which can meet the requirements of stable installation of NTC and fuse, thereby greatly improving the practicality of the connection structure and having a wide range of potential for promotion.
[0023] It should be noted that the top of the main support plate 1 is fixed with four first reinforcing ribs 3 located outside the four first limiting holes 2 respectively, and the top of the main support plate 1 is fixed with second reinforcing ribs 5 located outside the second limiting holes 4. The opposite sides of the first limiting holes 2 on both the left and right sides are open. The first reinforcing ribs 3 are U-shaped and set on the top of the main support plate 1. The opening direction of the first reinforcing ribs 3 is the same as the opening direction of the corresponding first limiting holes 2, so that the first reinforcing ribs 3 can play an auxiliary reinforcing role on the outside of the corresponding first limiting holes 2, thereby improving the structural strength of the main support plate 1 at the first limiting holes 2 and preventing bending damage.
[0024] In addition, the second reinforcing rib 5 is arranged in a ring on the top of the main support plate 1. The interior of the second reinforcing rib 5 is connected to the interior of the second limiting hole 4, so that the second reinforcing rib 5 can improve the structural strength of the surface of the main support plate 1 located at the second limiting hole 4.
[0025] It should also be noted that the limiting member 9 includes a fixing plate 91 fixed to the top of the connecting plate 8. Two side plates 92 are fixed to the front of the fixing plate 91, and an extension plate 93 is fixed to the top of the fixing plate 91. The side plates 92 are V-shaped and the two side plates 92 are symmetrically distributed from left to right. The second limiting hole 4 is located between the two side plates 92 on opposite sides. The extension plate 93 is T-shaped, so that after the NTC component body 11 enters the interior of the second limiting hole 4, it can be normally limited by the two side plates 92 and can rest against the extension plate 93, which facilitates the subsequent circuit connection work.
[0026] It is understandable that the fuse element body 10 is inserted between the inner sides of the two first limiting holes 2 on the front or the two first limiting holes 2 on the back, so that the fuse element body 10 can be properly installed. The protrusion of the arc-shaped limiting plate 7 is the top, and the bottom of the arc-shaped limiting plate 7 is the recessed part, which makes it easy for the annular part at the bottom of the NTC element body 11 to be fitted, thus playing a certain limiting role.
[0027] The working principle of the above embodiments is as follows:
[0028] When using this connection structure, the fuse element body 10 is placed between the inner sides of the two first limiting holes 2 on the front or the two first limiting holes 2 on the back. Then, the NTC element body 11 is passed through the inside of the second limiting hole 4, and the lower annular part of the NTC element body 11 is sleeved on the outside of the arc-shaped limiting plate 7. The limiting member 9 can appropriately limit the outside of the NTC element body 11, thus completing the limiting work of the fuse element body 10 and the NTC element body 11, so that they can be normally connected through the internal wires and circuit board.
[0029] Compared with existing technologies, the integrated connection structure of the rice cooker's NTC and fuse, through the cooperation of the main support plate 1, the first limiting hole 2, the second limiting hole 4, the arc-shaped limiting plate 7, and the limiting component 9, can simultaneously provide connection support for the NTC and the fuse, making it versatile. Only one connecting bracket is needed to complete the connection of two brackets, saving actual production costs. It also provides a certain limiting function, meeting the requirements for stable installation of the NTC and fuse, thus greatly improving the practicality of the connection structure. It has broad application potential and solves the problem that existing NTC and fuse connection structures all use separate brackets and lack versatility, resulting in high actual costs.
