Technical Field
[0001] The utility model relates to the technical field of metal base plate assembly, in particular to a spliced metal base plate. Background Art
[0002] A metal base plate is a special printed circuit board, which is made by the three-in-one composite of a metal layer (such as thin metal plates of aluminum, aluminum alloy, copper, iron, molybdenum, silicon steel, etc.), an insulating dielectric layer (such as modified epoxy resin, PI resin, PPO resin, etc.) and copper foil (electrolytic copper foil, rolled copper foil, etc.). This structure is called a metal base copper clad laminate, and a printed circuit is made on it to form a so-called metal base printed circuit board (MCPCB). Due to its unique structure and materials, the metal base plate has excellent thermal conductivity, electrical insulation performance and machining performance, and is widely used in electronic devices that require high thermal conductivity and high reliability.
[0003] The classification of metal base plates mainly includes aluminum base plates, copper base plates, etc. Among them, aluminum base plates are widely used in various electronic devices due to their good thermal conductivity and machining performance, such as input and output amplifiers, balanced amplifiers of audio devices, CPU boards, floppy disk drives, power supplies of computers, and electronic regulators, igniters, power controllers of automobiles, etc. Copper base plates are suitable for high-frequency electronic devices, such as radio frequency (RF) circuits and microwave applications, due to their excellent electrical conductivity and high-frequency performance. In addition, there are other types of metal base plates such as iron base plates, but the application of iron base plates is relatively less.
[0004] First, during the connection process of the metal base plate, most of them use welding to connect the two. In this way, when one end is damaged, it cannot be replaced individually, but the whole needs to be replaced, resulting in trouble during the later assembly process. Content of the Utility Model

A receiving plate is arranged inside the second metal base plate, and a slot is opened inside the receiving plate, and the slot is adapted to the insertion plate.
[0009] In addition, a preferred structure is that a limiting groove is formed on one side of the inserted plate, and the limiting groove is adapted to the positioning groove.
[0010] In addition, a preferred structure is that a limiting hole is formed at the top of the inserted plate, and the limiting hole is adapted to the positioning hole formed at the top of the inserted plate.
[0011] In addition, a preferred structure is that a limiting rod is inserted into the top of the inserted plate, and an assembly groove is formed in the rod body of the limiting rod.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Refer to Figures 1-5 , a spliced metal base plate, including a first metal base plate 1, an insertion plate 101 is arranged inside the first metal base plate 1, and a positioning groove 102 is opened on one side of the insertion plate 101;
[0024] A positioning hole 103 is opened at the top of the insertion plate 101, and a second metal base plate 2 is arranged on the other side of the first metal base plate 1. A plate to be inserted 21 is arranged inside the second metal base plate 2, an insertion slot 23 is opened inside the plate to be inserted 21, and the insertion slot 23 is adapted to the insertion plate 101.
[0025] Wherein, a limiting groove 22 is opened on one side of the plate to be inserted 21, and the limiting groove 22 is adapted to the positioning groove 102.
[0026] At the same time, a limiting hole is opened at the top of the plate to be inserted 21, and the limiting hole is adapted to the positioning hole 103 opened at the top of the plate to be inserted 21.
[0027] In addition, a limiting rod 24 is inserted into the top of the plate to be inserted 21, and an assembly groove 2401 is opened on the rod body part of the limiting rod 24, and the assembly abrasion 2401 is used for limiting.
[0028] And, the positioning hole 103 penetrates through the insertion plate 101, and the positioning groove 102 penetrates through horizontally, and the positioning groove 102 also penetrates through the positioning hole 103 in the vertical direction.
[0029] Furthermore, when the insertion plate 101 is inserted into the inside of the plate to be inserted 21, the limiting rod 24 is inserted into the limiting hole, and the limiting post 31 is inserted into the inside of the insertion slot 23, and a pull handle 3 is arranged at one end of the limiting post 31.
[0030] Moreover, when the limiting post 31 is inserted into the inside of the insertion slot 23, the limiting post 31 is adapted to the assembly groove 2401.
[0031] In this embodiment, when assembling the two metal base plates, first install the insertion plate 101 inside the first metal base plate 1, and set the inserted plate 21 inside the second metal base plate 2. Then, open positioning holes 103 and limit holes at the tops of the insertion plate 101 and the inserted plate 21, and open positioning grooves 102 and limit grooves 22 on the sides of the insertion plate 101 and the inserted plate 21.
[0032] Since the two metal base plates need to be assembled, a slot 23 is opened on the outside of the inserted plate 21. When the insertion plate 101 is inserted into the slot 23, first, the positioning hole 103 on the insertion plate 101 will coincide with the limit hole on the inserted plate 21, and the positioning groove 102 on the side of the insertion plate 101 will coincide with the limit groove 22 of the inserted plate 21. Also, the limit groove 22, the positioning groove 102, and the limit hole coincide with each other. Therefore, an assembly groove 2401 needs to be opened on the limit rod 24 during assembly.
[0033] Then, first insert the side of the limit rod 24 with the assembly groove 2401, and insert the limit post 31 into the outer limit groove 22 through the pull handle 3, so that the limit post 31 and the assembly groove 2401 are assembled with each other, enabling the stable assembly of the first metal base plate 1 and the second metal base plate 2.
[0034] If disassembly and replacement are required, only need to repeat the above operations in reverse to disassemble the two plates.
[0035] In this utility model, first, by setting the insertion plate 101 and the inserted plate 21 between the two metal base plates, the positions of the two can be limited. Then, by opening limit holes, opening the assembly groove 2401 on the limit rod 24, and through the assembly of the limit post 31 and the assembly groove 2401, the first metal base plate 1 and the second metal base plate 2 can be stably assembled and can be quickly disassembled.
[0036] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
