Problems solved by technology

In the process of product processing, surface treatment is carried out on the combination of metal and plastic in the later stage, such as anodizing treatment, etc. In the process of surface treatment, it is necessary to conduct all metal parts. Soldering conduction of each metal part needs to process the slot for the metal rod to be plugged in first. The processing process of the whole product shell is more complicated and the processing cost is higher. Moreover, the conduction effect between the metal parts is not ideal, and the yield rate lower

preparation example Construction

[0029] see Figure 1 to Figure 3 , according to a method for preparing a terminal housing 10 provided in an embodiment, the steps include:

[0030] S100 , providing a casing 100 to be processed, the casing 100 has a groove 150 , and a plastic part 200 is formed in the groove 150 by injection molding. The casing 100 can be classified into two types: one is integrated; the other is insulated by the plastic part 200 , that is, the plastic part 200 separates the casing 100 to form multiple parts spaced apart from each other. After injection molding, the plastic part 200 fills the groove 150 , and the back of the casing and the plastic part 200 together form the convex hull 210 , and the convex hull 210 corresponds to the area of ​​the groove 150 .

[0031] S200, coating conductive ink on the plastic part, and the housings on both sides adjacent to the plastic part are electrically connected by the conductive ink. For the structure with convex hull on the back of the housing, a n...

Embodiment 1

[0043]The convex hulls 210 at the upper and lower ends of the back of the housing are respectively processed into notches, so that the bottom of the notch is on the same plane as the back of the housing, and after the conductive ink is coated in the two pre-coated areas 160 on the back of the housing, the The casing is baked in a baking oven, the baking temperature is set to 60° C., and the baking time is set to 5 minutes. After baking, the casing is taken out of the baking oven to obtain a semi-finished casing.

[0044] Brush the UV protective glue twice on the conductive ink layer of the semi-finished shell. After the first brushing, use ultraviolet radiation to cure the first layer of UV protective glue, then brush the second layer of UV protective glue, and then use ultraviolet radiation to cure the second layer of UV protective glue. Secondary UV protective glue curing. Brush the UV protective glue twice on the conductive ink layer of the semi-finished shell. After the su...

Embodiment 2

[0046] The convex hulls 210 at the upper and lower ends of the back of the housing are respectively processed into notches, so that the bottom of the notch is on the same plane as the back of the housing, and after the conductive ink is coated in the two pre-coated areas 160 on the back of the housing, the The casing is baked in a baking oven, the baking temperature is set to 50° C., and the baking time is set to 15 minutes. After baking, the casing is taken out of the baking oven to obtain a semi-finished casing. Similarly, brush the UV protective glue twice on the conductive ink layer of the semi-finished shell, and use ultrasonic waves to remove the conductive ink layer and the protective layer after the surface treatment of the semi-finished shell to obtain the finished shell.

Abstract

The invention relates to a terminal shell and a preparing method thereof. The preparing method of the terminal shell includes the steps that a to-be-machined shell is provided, the shell is provided with a groove, and plastic parts are formed in the groove; the plastic parts are coated with conductive ink so that the parts, on the two sides of the groove, of the shell are conductive; the conductive ink is cured to form an conductive ink layer, and a semi-finished product of the shell is obtained; a protection layer is formed on the conductive ink layer; the semi-finished product, with the surface coated with the protection layer, of the shell is subject to surface treating and machining; and the conductive ink layer and the protection layer of the semi-finished product, completing surface treating and machining, of the shell are removed. By means of the preparing method of the terminal shell, as the conductive ink has mobility, the shell can have good electrical conductivity, the overall preparing process is simple in operation, efficiency is high, and the machining cost is low.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a terminal shell and a preparation method thereof. Background technique [0002] With the demand for miniaturization, thinner, and fashionable development of 3C electronic products, more and more metal materials, such as aluminum alloys and titanium alloys, are used for the casings of existing electronic products. [0003] Due to the shielding problem of the antenna signal of communication electronic products, it is necessary to process the antenna slot on the metal parts to solve the signal problem of communication electronic products. In the process of product processing, surface treatment is carried out on the combination of metal and plastic in the later stage, such as anodizing treatment, etc. In the process of surface treatment, it is necessary to conduct all metal parts. Soldering conduction of each metal part needs to process the slot for the metal rod to be ...
