Shenzhen Johan Material Technology Co., Ltd. has obtained a patent for shielding cover structure for circuit boards, enhancing the overall shielding effect of the shielding cover structure

On May 14, 2025, the financial sector reported that the China National Intellectual Property Administration information showed that Shenzhen Johan Material Technology Co., Ltd. had obtained a patent entitled "a shield cover structure for circuit boards", the authorization announcement number was CN222852436U, and the application date was July 2024.

The patent abstract shows that the present utility model relates to the technical field of shielding cover structure, and discloses a shielding cover structure for circuit boards, comprising: a first cover layer, which is set as a rigid cover body and can shield electromagnetic interference outside the first cover layer; A second cover layer is stacked with the first cover layer, and the second cover layer is set on at least one side of the first cover layer, which can shield electromagnetic interference outside the second cover layer. The second cover layer includes a stacked tin plating layer and a substrate layer, and the tin plating layer is set on the side of the substrate layer away from the first cover layer; An adhesive layer is provided between the first cover layer and the second cover layer, wherein the first cover layer is bonded to the substrate layer through the adhesive layer. This utility model provides a shielding cover structure for circuit boards, which can enhance the overall shielding effect of the shielding cover structure, adapt to automated production lines, and improve production efficiency.

According to Tianyancha data, Shenzhen Johan Material Technology Co., Ltd., established in 2011 and located in Shenzhen, is an enterprise mainly engaged in the manufacturing of computers, communications, and other electronic equipment. The registered capital of the enterprise is 8.25 million RMB. Through big data analysis by Tianyancha, Shenzhen Johan Material Technology Co., Ltd. has invested in 7 enterprises and participated in 3 bidding projects.

According to the information of the China National Intellectual Property Administration, Shenzhen Johan Material Technology Co., Ltd. has obtained a patent named "Conductive Elastic Connector", the authorization announcement number is CN 222168707 U, and the application date is February 2024. The patent abstract shows that the present utility model discloses a conductive elastic connector, comprising a conductive elastic body and a metal base. The metal base comprises a plate body and a fastener. The fasteners are provided on both sides of the plate body, and the conductive elastic body is pressed on the upper side of the plate body. The fasteners located on the opposite sides of the plate body fasten the conductive elastic body to the plate body, and at least one side of the plate body extends outward beyond the bottom area of the conductive elastic body. In the present utility model, by extending at least one side of the board outward beyond the bottom area of the conductive elastic body, the part of the board extending outside the bottom area of the conductive elastic body can still maintain high electrical connection reliability with the grounding area through metal welding even in scenarios where SMT welding cannot be used for the conductive elastic connection component; Meanwhile, no adhesive is required between the conductive elastomer and the metal base, resulting in lower resistance.

Shenzhen Johan Materials Technology Co., Ltd. has recently been granted a new patent by the China National Intellectual Property Administration. Titled “Electromagnetic Shielding Film, Its Preparation Method, and Application,” the patent announcement number is CN116981239B. Filed in July 2023, this patent demonstrates the company's technological innovation and R&D capabilities in the field of electromagnetic shielding materials.

Shenzhen Johan Materials Technology Co., Ltd. was established in 2011 with a registered capital of RMB 8.25 million. Headquartered in Shenzhen, the company specializes in the manufacturing of computers, communications, and other electronic equipment. According to Tianyancha data, the company currently holds 56 patents and 14 administrative permits, has invested in 7 enterprises, and participated in 3 bidding projects, demonstrating its active presence and influence within the industry.
