Problems solved by technology

However, the way of snap hook engagement and riveting is prone to defects such as large gaps and easy loosening, which will affect the strength of the joint
When the thickness of the joint is relatively thin, it is easy to generate fracture stress and affect the strength of the joint by using hooks and riveting.

Embodiment Construction

[0015] The combination of metal and plastic and its manufacturing method of the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

[0016] See figure 1 and figure 2 The metal-plastic combination part 10 of the preferred embodiment 1 of the present invention is an electronic device casing, which includes a metal body 11 and a plastic part 12 combined with the metal body 11 . The metal body 11 is generally a rectangular metal cover, and at least one positioning portion 110 is provided on a side of the metal body 11 combined with the plastic portion 12 for tightly combining with the plastic portion 12 to form a positioning structure during the molding process. The material of the metal body 11 can be selected from one of magnesium alloy, aluminum alloy or titanium alloy.

[0017] The plastic part 12 is generally long and can be formed on one side of the metal body 11 where the positioning part 110 is di...

Abstract

The invention provides a combination piece of metal and plastic, which comprises a metal body and a plastic part, wherein the metal body and the plastic part are formed integrally by adopting embedded forming technology; at least one positioning structure is formed on a combine part of the metal body and the plastic part; a material of the metal body is selected from one of a magnesium alloy, an aluminum alloy and a titanium alloy; and a material of the plastic part is selected from one of a liquid crystal high polymer, polyphenylene sulphide and polybutylene terephthalate. The invention also provides a manufacture method for the combination piece of the metal and the plastic. The combination piece of the metal and the plastic has the advantages of high strength, difficult deformation and cracking and adaptability in thinning design.

Description

technical field [0001] The invention relates to a combination piece of metal and plastic and a manufacturing method thereof. Background technique [0002] Combinations of metal and plastic are common in daily life, such as the housings of some laptops or mobile phones. In order to prevent the electromagnetic shielding phenomenon produced by metals from affecting the transmission and reception of signals by the antenna, the antenna cover of the housing is usually made of plastic parts. Others Some are metal parts. The combination of metal parts and plastic parts directly affects the strength of the shell. [0003] An existing combination of metal and plastic, which fixedly connects the plastic part to the metal part by means of snap-fit ​​or riveting. However, the way of snapping and riveting tends to produce defects such as large gaps and easy loosening, which affects the strength of the joint. When the thickness of the joint is relatively thin, it is easy to generate fra...
