Description

Technical Field

[0001] The utility model relates to the field of snap-on shells, and particularly to a snap-on shell. Background Technique

[0002] A snap is a mechanism for the embedded connection or overall locking of one part to another part, usually used for the connection of plastic parts, and its material is usually composed of a plastic material with a certain flexibility. The biggest feature of snap connection is that it is convenient for installation and disassembly, and can be disassembled without tools. Now the snap connection technology has been widely applied to the connection of automotive interior parts. Through reasonable design, snap connection can achieve rapid assembly and disassembly, and the disassembly and assembly process can even be carried out without auxiliary tools. At the same time, snap connection is also a connection method that can maintain the integrity of the product appearance well. Especially in the field of consumer electronics products with high requirements for appearance, snap connection is the most widely used connection method.

[0003] A snap consists of a positioning part and a fastening part. The function of the positioning part is to guide the snap to reach the installation position smoothly, correctly and quickly during installation. The function of the fastening part is that the detachable fastening part is usually designed so that when a certain separation force is applied, the snap will come off and the two connecting parts will separate. This kind of snap is often used to connect two parts that need to be disassembled frequently. The non-detachable fastening part requires manual deflection of the fastening part to disassemble the two parts, and is mostly used for the connection and fixation of parts that are not disassembled during use.

[0004] In the existing technology, many snap-on shell structures are simple. When encountering harsh environments, the snap structure may expand and contract due to heat and cold, resulting in huge problems with the sealing and safety of the shell. At the same time, there is no protective material filled inside, which may cause impurities to appear in the internal electronic components, leading to damage to the electronic components. Content of the Utility Model
