Description

Technical Field

[0001] This utility model relates to the field of PTC water heater technology, and in particular to a wedge-shaped electrode. Background Technology

[0002] Currently, in PTC water heater products, electrical components typically use solderless electrical connections, especially in the connection between the electrode lugs of the PTC module and the upper conductive module. To improve assembly efficiency, solderless connections are more commonly used. Most current electrode sheets use a flat plate structure with uniform wall thickness, although some use tapered electrodes. Regardless of the type, the lug position uses a flat plate structure with uniform wall thickness. This structure has the following drawbacks: 1. The thickness of the electrode lugs is usually thin, less than 1mm. When there is a need for increased assembly height, if the lug height is designed too high, it will lose its rigidity during insertion, making the lugs prone to bending and increasing assembly difficulty. Simply adding chamfers to the sides for reinforcement does not significantly improve the situation. 2. When the electrode is a tapered electrode structure, excessively high lugs hinder the forming of aluminum extrusion profiles, easily causing product damage, dimensional defects, and other defects.

[0003] Therefore, it is necessary to provide a wedge electrode that can meet different assembly distance requirements while ensuring sufficient rigidity. Utility Model Content

[0004] The purpose of this invention is to provide a wedge-shaped electrode that can meet different assembly distance requirements while ensuring sufficient rigidity.

[0005] To achieve the above objectives, this utility model provides a wedge-shaped electrode, including an electrode sheet body and an electrode lug disposed on the electrode sheet body. The electrode lug includes a lug transition portion and a lug mounting portion. The lower end of the lug transition portion is connected to the upper surface of the electrode sheet body, and the lug transition portion is bent and extends upward relative to the electrode sheet body. The upper end of the lug transition portion is connected to the lug mounting portion. The thickness of the lug transition portion is greater than the thickness of the lug mounting portion, and the plane on which the lug mounting portion is located is different from the plane on which the electrode sheet body is located.

[0006] Preferably, the electrode sheet body has a wedge-shaped structure.

[0007] Preferably, the electrode body has a wide upper end and a lower end that gradually narrows downwards.

[0008] Preferably, of the two opposite sides of the electrode sheet body, one side is vertically distributed in the up-down direction, and the other side is obliquely distributed in the up-down direction.

[0009] Preferably, the lug assembly is located on one side of the vertically distributed side of the electrode body.

[0010] Preferably, the lug assembly is parallel to the side surface of the electrode plate body that is vertically distributed.

[0011] Preferably, the electrode body has a contact side for contacting and energizing the PTC sheet.

[0012] Preferably, the contact side is provided with a plurality of slots to divide the contact side into a plurality of contact areas that correspond one-to-one with the PTC sheet.

[0013] Preferably, all the slots are distributed along the same horizontal direction.

[0014] Preferably, the slots are distributed at equal intervals.

[0015] Compared with the prior art, the wedge-shaped electrode lug of this utility model has a lug transition part and a lug assembly part. By connecting the lower end of the lug transition part to the upper surface of the electrode body, bending the lug transition part relative to the electrode body and extending it upward, and connecting the upper end of the lug transition part to the lug assembly part, the position of the electrode lug relative to the electrode body has a variable cross-section structure. Moreover, since the thickness of the lug transition part is greater than the thickness of the lug assembly part, the relatively thicker lug transition part and the relatively thinner lug assembly part allow the electrode lug to meet different assembly distance requirements. Even if the entire electrode lug is high, it can ensure sufficient rigidity, prevent deformation, and ensure good assemblability. Attached Figure Description

Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] Please see Figures 1 to 3The wedge-shaped electrode 100 of this utility model includes an electrode body 1 and an electrode lug 2 disposed on the electrode body 1. The electrode lug 2 includes a lug transition portion 21 and a lug mounting portion 22. The lower end of the lug transition portion 21 is connected to the upper surface of the electrode body 1, and the lug transition portion 21 is bent relative to the electrode body 1 and extends upward. The upper end of the lug transition portion 21 is connected to the lug mounting portion 22. The thickness of the lug transition portion 21 is greater than the thickness of the lug mounting portion 22. The plane on which the lug mounting portion 22 is located is different from the plane on which the electrode body 1 is located.

[0025] Since the electrode lug 2 is provided with a lug transition portion 21 and a lug mounting portion 22, and the lug transition portion 21 is bent and extends upward relative to the electrode sheet body 1, the position of the electrode lug 2 of the wedge electrode 100 of this utility model has a variable cross-section structure relative to the electrode sheet body 1. Furthermore, since the thickness of the lug transition portion 21 is greater than the thickness of the lug mounting portion 22, the lug transition portion 21 located in the lower half and close to the electrode sheet body 1 is relatively thick, while the lug mounting portion 22 located in the upper half and close to the contact mounting position is relatively thin. Therefore, it is convenient for the electrode lug 2 to be assembled with external components, and the electrode lug 2 can meet different assembly distance requirements. Even if the entire electrode lug 2 is high, it can ensure sufficient rigidity, prevent deformation, and ensure good assemblability.

[0026] Please see Figure 3 In one embodiment, the electrode body 1 has a wedge-shaped structure. Specifically, the electrode body 1 has a wide upper end and a lower end that gradually narrows downwards.

[0027] In one embodiment, on two opposite sides of the electrode sheet body 1, one side is vertically distributed along the vertical direction, while the other side is obliquely distributed along the vertical direction. For example... Figure 3 As shown in the figure, A1 indicates the side of the electrode body 1 where it is vertically distributed, and A2 indicates the side of the electrode body 1 where it is obliquely distributed. Specifically, the lug mounting part 22 is located on one side of the vertically distributed side of the electrode body 1, but is not limited thereto. More specifically, the lug mounting part 22 is parallel to the vertically distributed side of the electrode body 1 to facilitate the assembly of the lug mounting part 22, but is not limited thereto.

[0028] Please see Figure 1 and Figure 2 In one embodiment, the electrode body 1 has a contact side for contacting and energizing with a PTC chip. The wedge-shaped electrode 100 of this invention can use a multi-chip structure, meaning one wedge electrode 100 contacts and energizes multiple PTC chips. Specifically, as... Figure 2As shown in the figure, A2 indicates the contact side of the electrode body 1. This contact side is also the side of the electrode body 1 where it is inclined, but this is not a limitation. Furthermore, the contact side has several slots 11 to divide it into several contact areas that correspond one-to-one with the PTC sheets, thus ensuring good contact between each PTC sheet and the electrode body 1 after assembly. In each mating contact area, the electrode body 1 has independent elastic adhesion, effectively preventing abnormal situations where some PTC sheets are not properly adhered, ensuring stable and normal power and other performance of the entire machine. Specifically, the slots 11 are distributed along the same horizontal direction, but this is not a limitation. More specifically, the slots 11 are evenly spaced, but this is not a limitation.

[0029] In summary, the electrode lug 2 of the wedge electrode 100 of this utility model, by setting a lug transition portion 21 and a lug mounting portion 22, connects the lower end of the lug transition portion 21 to the upper surface of the electrode sheet body 1, bends the lug transition portion 21 relative to the electrode sheet body 1 and extends it upward, and connects the upper end of the lug transition portion 21 to the lug mounting portion 22, so that the position of the electrode lug 2 relative to the electrode sheet body 1 has a variable cross-section structure. Moreover, since the thickness of the lug transition portion 21 is greater than the thickness of the lug mounting portion 22, the relatively thicker lug transition portion 21 and the relatively thinner lug mounting portion 22 can meet different assembly distance requirements. Even if the entire electrode lug 2 is high, it can ensure sufficient rigidity, prevent deformation, and ensure good assemblability. Therefore, the wedge electrode 100 of this utility model has the characteristic of flexible design. When there are different assembly size requirements, the height and lateral offset distance of the lug transition part 21 of the electrode lug 2 can be flexibly adjusted. Secondly, the wedge electrode 100 of this utility model can be made of aluminum alloy extrusion molding, which can meet the customized design and development of different shapes.
