Description

Technical Field

[0001] This utility model relates to the field of double-sided circuit board technology, and in particular to a lightweight double-sided circuit board. Background Technology

[0002] A double-sided circuit board is a printed circuit board with conductive copper layers on both sides. The circuits on both sides are connected by through holes, which allows for more complex circuit layouts in a limited space without significantly increasing the size of the circuit board.

[0003] However, in the existing technology, double-sided circuit boards need to have conductive copper layers on both sides. However, in order to ensure that there is enough volume to accommodate different components, existing double-sided circuit boards use relatively thick boards as carriers. At this time, the weight of the circuit board is large, which will affect the normal use of some devices, reduce the battery life of some devices, and increase energy consumption. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that uses relatively thick boards as carriers, which results in a large weight of circuit boards, affecting the normal use of some devices, reducing the battery life of some devices, and increasing energy consumption. Therefore, a lightweight double-sided circuit board is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight double-sided circuit board, comprising a first circuit board and a second circuit board, a partition plate fixedly connected between the first circuit board and the second circuit board, a first positioning block fixedly installed at each of the four corners of the upper surface of the partition plate, the first positioning block being located at the four corners of the first circuit board, a vertical plate fixedly installed on the lower surface of the partition plate, the vertical plate being fixedly connected to the second circuit board.

[0006] Preferably, a second positioning block is fixedly installed at the four corners of the lower surface of the partition plate, and the second positioning block is located at the four corners of the second circuit board.

[0007] Preferably, a notch is provided at the junction of the first positioning block and the second positioning block.

[0008] Preferably, a support plate is fixedly connected between the two vertical plates, and the second circuit board is fixedly installed inside the support plate.

[0009] Preferably, the inner side of the partition plate has a through hole.

[0010] Preferably, pins are fixedly installed at the edges of the first circuit board and the edges of the second circuit board.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a partition plate is set to distinguish the first circuit board and the second circuit board. The upper surface of the first circuit board is provided with a first positioning block to determine the position of the first circuit board, and the lower surface is provided with a vertical plate to determine the position of the second circuit board. The overall hollow state can accelerate the heat dissipation speed. Moreover, compared with the traditional whole plate, the whole structure has the effect of smaller volume and lighter weight, making it more lightweight.

[0013] 2. In this utility model, by separating the second circuit board from the first circuit board by a certain distance, the existence of through holes not only allows the circuits of the first circuit board and the second circuit board to be connected, but also allows air to circulate normally, and the pins can be used to connect the first circuit board and the second circuit board to other devices.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a lightweight double-sided circuit board, including a first circuit board 1 and a second circuit board 2. A separator component 3 is fixedly connected between the first circuit board 1 and the second circuit board 2. The separator component 3 includes a separator plate 31. A first positioning block 32 is fixedly installed at each of the four corners of the upper surface of the separator plate 31. The first positioning block 32 is located at the four corners of the first circuit board 1. A vertical plate 34 is fixedly installed on the lower surface of the separator plate 31. The vertical plate 34 is fixedly connected to the second circuit board 2. A second positioning block 33 is fixedly installed at each of the four corners of the lower surface of the separator plate 31. The second positioning block 33 is located at the four corners of the second circuit board 2. A notch 36 is provided at the junction of the first positioning block 32 and the second positioning block 33.

[0022] The specific settings and functions of this embodiment are described below. The first circuit board 1 is fixedly installed on the first positioning block 32 at the top of the partition plate 31, and the second circuit board 2 is fixedly installed on the vertical plate 34 below the partition plate 31 to ensure the structural stability of the first circuit board 1 and the second circuit board 2. The partition plate 31 connects the first circuit board 1 and the second circuit board 2 to form a double-sided circuit board. The second positioning block 33 is used to connect with other carrier structures to ensure the stability of the partition plate 31. The overall hollow structure allows air to flow and remove the heat from the first circuit board 1 and the second circuit board 2.

[0023] The second positioning block 33 is located on the lower surface of the partition plate 31, and is a distance away from the corner of the partition plate 31, thus forming a notch 36. The presence of the notch 36 can improve the stability of the partition plate 31 on other carriers and prevent shaking. Compared with the traditional fixed structure of a whole plate, it can ensure its own stability while also having the effect of smaller size and lighter weight.

[0024] Example 2: Figure 1 and Figure 2 As shown, a support plate 35 is fixedly connected between the two vertical plates 34. The second circuit board 2 is fixedly installed inside the support plate 35. A through hole 37 is opened on the inner side of the partition plate 31. Pins 4 are fixedly installed at the edge of the first circuit board 1 and the edge of the second circuit board 2.

[0025] The overall effect of this embodiment is that the support plate 35 connected between the vertical plates 34 is used to support the second circuit board 2, the vertical plates 34 separate the second circuit board 2 from the first circuit board 1 by a certain distance to allow normal air circulation, the presence of the through hole 37 is used to ensure that the circuits of the first circuit board 1 and the second circuit board 2 can be connected normally, and the pin 4 is used to connect the first circuit board 1 and the second circuit board 2 to other devices.

[0026] The usage and working principle of this device are as follows: The first circuit board 1 is fixedly installed on the first positioning block 32 at the top of the partition plate 31, and the second circuit board 2 is fixedly installed on the vertical plate 34 below the partition plate 31 to ensure the structural stability of the first circuit board 1 and the second circuit board 2. The support plate 35 connected between the vertical plates 34 is used to support the second circuit board 2. The vertical plate 34 separates the second circuit board 2 from the first circuit board 1 by a certain distance, so that air can pass through the through hole 37 to carry away the heat in the first circuit board 1 and the second circuit board 2, and can also allow the circuit of the first circuit board 1 and the second circuit board 2 to be normally connected.

[0027] The partition plate 31 connects the first circuit board 1 and the second circuit board 2 to form a double-sided circuit board. The second positioning block 33 is used to connect with other carrier structures to ensure the stability of the partition plate 31. With the help of the pin 4, the stability of the entire partition plate 31 can be guaranteed. The second positioning block 33 is located on the lower surface of the partition plate 31 and is a certain distance away from the corner of the partition plate 31, thus forming a notch 36. The presence of the notch 36 can improve the stability of the partition plate 31 on other carriers.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
