New description: [New technical field] This creation is about the field of computer accessories technology, especially a backplane structure for cpu installation. [Prior Art] There are two main types of CPU backplanes. One is plastic injection molding, and the other is steel stamping. The two types of backplanes have the following disadvantages: 1. The plastic backing is not strong enough. After the CPU fan is easily pulled and deformed; and 2, the steel back plate is strong enough, but the weight is heavy, heavy, and costly. [New Content] The purpose of this creation is to comprehensively improve the deficiencies of the prior art and provide a good quality, lightweight, and durable CPU backplane structure. In order to achieve the above objectives, the present invention adopts the following technical solutions: A CPU backplane structure, including a plastic backplane, is embedded with a reinforcing block inside the plastic backboard, and the reinforcing block is a metal plate, a metal strip or a metal frame. The reinforcing block is injection molded together with the plastic backing plate, and the reinforcing block is provided with a screw hole for fixed installation. The reinforcing block is a stamping part, and a process hole is further formed on the upper part to penetrate the upper and lower sides to form a process hole when the molding is formed, thereby avoiding injection delamination. M360393 This creation embeds a reinforcing block inside the plastic backing plate to achieve partial reinforcement or full reinforcement, thereby enhancing the strength of the plastic backing plate and enhancing the tensile and bending resistance, and ensuring the product is light and low in cost. [Embodiment] The present invention will be further described below with reference to the accompanying drawings: Referring to Figures 1 to 4, the CPU backboard of the present invention embeds a reinforcing block 20 inside the plastic backboard ίο to achieve partial reinforcement or full reinforcement. This enhances the use strength of the plastic back sheet and enhances tensile and bending resistance. The reinforcing block 20 may be a metal plate, a metal strip or a metal frame; the metal plate is a plate body similar in size to the plastic back plate, and the metal frame is a frame designed to conform to the periphery of the plastic back plate. In this embodiment, the reinforcing block 2 is The metal strip, as shown in Figure 5A and Figure 5b, is stamped. The reinforcing block and the plastic backing plate 10 are put into the mold for injection molding. The plastic backing plate 10 shown in Fig. 1 has two reinforcing blocks 2G arranged in parallel, and the reinforcing and easy to pull the deformed part 'guarantee CPU & CPU fan installation use. The reinforcing block 2 is provided with a threaded hole 21 for fixed installation, and the threaded hole 21 and the reinforcing block 2 are integrally formed, and no additional nut is required, thereby reducing the cost. As shown in Fig. 5A and Fig. 5B, the reinforcing block 2 is a stamping part, and the left and right sides are also bent to form a reinforcing rib 23 to increase the strength. On the reinforcing block 2〇, a process hole 22 is provided to reach the upper and lower sides; In this way, during the injection molding, the rubber can be connected to the upper and lower sides through the process hole 22, and the M360393 layer is removed, so that the injection molding is more compact and the product structure is excellent. This product not only has the advantages of light weight and low cost of pure plastic back sheet, but also has the advantages of the strength of steel back sheet, which improves the usability and economy of the product.
