Description
Technical Field
[0001] The present invention relates to the technical field of terminal equipment, and in particular to a terminal equipment with an electrical connection structure. Background Art
[0002] On June 15, 2023, the European Union passed a bill on quick-disassembly requirements for consumer electronics. The bill clearly prohibits the use of glue to bond batteries in the consumer electronics field to promote the maintainability and environmental protection of the product. Therefore, quick-disassembly structural parts are required to design consumer electronics products.
[0003] After using the mobile terminal disassembly structure design that meets the EU battery quick-disassembly requirements, the battery cover and display screen of the mobile terminal need to add independent brackets. Due to the limitation of the thickness of the whole machine, these brackets are designed to be relatively thin. In order to meet the reliability requirements of the strength of the structural parts, it is necessary to increase the strength of these brackets with in-film injection-molded metal materials. At the same time, it is also necessary to meet the electrical performance requirements of electromagnetic radiation certification (such as RSE, de-sense, OTA, etc.), and each metal part needs to be connected to the main reference ground.
[0004] See also Figures 1 to 3 In order to fully ground the metal parts of the mobile terminal so that the signal can flow back to the main reference ground, the traditional design requires a large amount of conductive foam or grounding springs to connect the metal parts of the mobile terminal to the main ground. This design, which increases the amount of electrical connection materials to connect the various structures into a whole, will increase material costs and development costs. The increase in electrical connection points will also lead to the risk of poor grounding reliability and stability of the entire machine. Summary of the invention
