Technical Field

[0001] The utility model relates to the field of microelectronic technology, and specifically relates to a metal composite electrode chip. Background Art

The design of this chip combines the advantages of different materials, such as high sensitivity, fast response, good stability, etc., and can further improve the characteristics of the electrode through the synergistic effect between materials, thereby expanding its application range.

[0003] In the manufacturing process of existing metal composite electrode chips, a variety of metal materials are required, including metals with high purity and special properties. The prices of these metals are relatively high, especially when using precious metals such as silver as the electrode material, the cost will increase significantly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a metal composite electrode chip to solve the problems raised in the above background art.

[0005] To solve the above technical problems, a metal composite electrode chip provided by the utility model includes an electrode chip. Two silver electrodes are fixedly installed on the outer wall of the electrode chip, and the inside of the electrode chip is made of aluminum.

[0006] Further, two circular plate ceramic chips are fixedly installed on the outer wall of the electrode chip. Two base metals are fixedly installed on the outer wall of the electrode chip. The base metals are located inside the circular plate ceramic chips, and the silver electrodes are located inside the base metals.

[0007] Further, the two silver electrodes, the circular plate ceramic chips and the base metals are respectively located on both sides of the electrode chip, and the shape of the silver electrodes is polygonal.

[0008] Further, two polygonal placement cavities are opened on the outer wall of the electrode chip, and the silver electrodes are fixedly installed inside the polygonal placement cavities.

[0009] Further, a polygonal weld seam is welded between the silver electrode and the electrode chip.

[0010] Further, a slot is opened on one side of the electrode chip, and the slot is located between the circular plate ceramic chip, the base metal, the polygonal weld seam and the silver electrode.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the present utility model, the price of aluminum is much lower than that of silver. Therefore, using aluminum as the main material of the electrode chip can significantly reduce the cost. By using aluminum paste on a large-area electrode chip, the conductivity similar to that of pure silver can be achieved, while the material cost is greatly reduced. The small-area silver electrodes covered on the surface not only enhance the reliability of the welding process, but also do not significantly increase the overall cost because of their small area. This makes the device more advantageous in terms of cost than the pure silver electrode chip.

The user only needs to insert one end of the tinned copper wire into the slot, and the slot will hold the tinned copper wire to prevent it from easily shifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0021] Refer to Figures 1 - 3 as shown, a metal composite electrode chip includes an electrode chip 1. Two silver electrodes 5 are fixedly installed on the outer wall of the electrode chip 1, and the inside of the electrode chip 1 is made of aluminum.

[0022] The price of aluminum is much lower than that of silver. Therefore, using aluminum as the main material for the electrode chip 1 can significantly reduce costs. By using aluminum paste on a large area of the electrode chip 1, a conductivity similar to that of pure silver can be achieved, while significantly reducing material costs. The small-area silver electrodes 5 covered on the surface not only enhance the reliability of the welding process but also, due to their small area, do not significantly increase the overall cost. This makes the device more cost-effective than the pure silver electrode chip 1.

[0023] See Figures 1 - 3 , two disc-shaped ceramic chips 2 are fixedly installed on the outer wall of the electrode chip 1, and two base metals 3 are fixedly installed on the outer wall of the electrode chip 1. The base metals 3 are located inside the disc-shaped ceramic chips 2, and the silver electrodes 5 are located inside the base metals 3.

[0024] The disc-shaped ceramic chips 2 have good insulation performance, which can ensure that no dangerous situations such as short circuits or electric shocks occur when the electrode chip 1 is working. The base metals 3 help with the distribution of heat inside the electrode chip 1, ensuring that heat can be effectively transferred to the radiator or other heat dissipation components, thereby maintaining the operation and temperature of the electrode chip 1 within a suitable range.

[0025] See Figure 1 , the two silver electrodes 5, the disc-shaped ceramic chips 2, and the base metals 3 are respectively located on both sides of the electrode chip 1. The shape of the silver electrodes 5 is polygonal.

[0026] The design of installing the disc-shaped ceramic chips 2, the base metals 3, and the silver electrodes 5 on both sides of the electrode chip realizes benefits such as optimized material costs, improved performance stability, enhanced reliability, and expanded application range. The polygonal shape of the silver electrodes 5 is to increase the contact area between the silver electrodes 5 and the electrode chip 1, enabling the silver electrodes 5 to be more stably connected to the electrode chip 1.

[0027] See Figure 3 , two polygonal placement cavities 7 are formed on the outer wall of the electrode chip 1, and the silver electrodes 5 are fixedly installed inside the polygonal placement cavities 7.

[0028] The polygonal placement cavities 7 provide storage space for the silver electrodes 5, enabling the silver electrodes 5 to fit more closely to the electrode chip 1. After the silver electrodes 5 are installed in the polygonal placement cavities 7, they will be more stable and will not easily fall off the outer wall of the electrode chip 1.

[0029] See Figures 1 - 2 , a polygonal weld seam 4 is welded between the silver electrodes 5 and the electrode chip 1.

[0030] The polygonal weld seam 4 is adapted to the shape of the silver electrodes 5, facilitating the welding of each side of the silver electrodes 5 to the outer wall of the electrode chip 1, enabling the silver electrodes 5 to be more stably welded to the outer wall of the electrode chip 1.

[0031] SeeFigure 1 , a slot 6 is provided on one side of the electrode chip 1. The slot 6 is located between the round plate ceramic chip 2, the base metal 3, the polygonal weld 4 and the silver electrode 5. The slot 6 is used to place the tinned copper wire.

[0032] When using the electrode chip 1, it is usually necessary to weld the tinned copper wire to the electrode chip 1. When welding the tinned copper wire, it is necessary to first place the tinned copper wire on the outer walls of the round plate ceramic chip 2, the base metal 3 and the silver electrode 5. During the welding process, the tinned copper wire may tilt. Therefore, it is necessary for the staff to hold the tinned copper wire. The slot 6 provides a space for the tinned copper wire to be inserted. The user only needs to insert one end of the tinned copper wire into the slot 6, and the slot 6 will hold the tinned copper wire to prevent it from easily shifting.

[0033] Working principle:

[0034] The price of aluminum is much lower than that of silver. Therefore, using aluminum as the main material of the electrode chip 1 can significantly reduce the cost. By using aluminum paste on the large-area electrode chip 1, the conductivity similar to that of pure silver can be achieved, while significantly reducing the material cost. The small-area silver electrode 5 covered on the surface not only enhances the reliability of the welding process, but also does not significantly increase the overall cost because of its small area. This makes the device more advantageous in terms of cost than the pure silver electrode chip 1.

[0035] When using the electrode chip 1, it is usually necessary to weld the tinned copper wire to the electrode chip 1. When welding the tinned copper wire, it is necessary to first place the tinned copper wire on the outer walls of the round plate ceramic chip 2, the base metal 3 and the silver electrode 5. During the welding process, the tinned copper wire may tilt. Therefore, it is necessary for the staff to hold the tinned copper wire. The slot 6 provides a space for the tinned copper wire to be inserted. The user only needs to insert one end of the tinned copper wire into the slot 6, and the slot 6 will hold the tinned copper wire to prevent it from easily shifting.
