Abstract

The present disclosure relates to a method for processing a terminal housing. The method comprises the following steps: processing a glue grabbing characteristic needing to be fixed on the metal shell; and connecting the adhesive grasping feature with an adhesive grasping structure on the metal shell to form the terminal shell. The technical scheme can change the grabbing glue characteristic into an independent part of the metal shell, avoids the grabbing glue characteristic from being influenced by the whole metal shell, and has the advantages that the grabbing glue characteristic manufacturing and processing method and the plastic material selection are diversified, so that the cost can be saved, and the design of the metal in-mold forming structure is enriched.

Description

Terminal shell machining method

Technical Field

The disclosure relates to the technical field of in-mold forming, in particular to a processing method of a terminal shell.

Background

In order to ensure the structural strength of the product, the design of the prior art adopts an Insert molding (Insert molding) technique, i.e. a metal structure is embedded in plastic to make up for the deficiency of the strength of the plastic product, so that the metal part and the plastic part of the product must be well combined, i.e. the adhesive-holding structure must be designed reasonably.

Disclosure of Invention

In order to overcome the problems in the related art, embodiments of the present disclosure provide a method for processing a terminal housing, so as to simplify the processing of the glue-grasping feature of the terminal housing and increase the selectivity and diversity of the design.

Provided is a processing method of a terminal housing, comprising the following steps:

processing a glue grabbing characteristic needing to be fixed on the metal shell;

and connecting the adhesive grasping feature with an adhesive grasping structure on the metal shell to form the terminal shell.

In one embodiment, the processing requires glue grasping features affixed to the metal shell, which may include:

and processing the glue grabbing characteristic needing to be fixed on the metal shell in a stamping mode.

and processing the rubber-catching characteristics to be fixed on the metal shell in a die-casting mode.

and processing the glue grabbing characteristic needing to be fixed on the metal shell in a metal injection molding mode.

In one embodiment, the connecting the adhesive grasping feature and the adhesive grasping structure on the metal shell may include:

and connecting the adhesive grabbing feature and an adhesive grabbing structure on the metal shell together in a welding mode.

and connecting the adhesive grabbing characteristic with an adhesive grabbing structure on the metal shell in an adhesive dispensing manner.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects:

the glue grabbing characteristic needs to be fixed on the metal shell through independent processing, so that the glue grabbing characteristic is changed into an independent part of the metal shell, the influence of the whole original metal shell on the glue grabbing characteristic is avoided, and the manufacturing and processing method and the plastic material selection of the glue grabbing characteristic have diversity, so that the cost can be saved, and the design of the metal in-mold forming structure is enriched.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Drawings

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and together with the description, serve to explain the principles of the invention.

Fig. 1A is a flow chart illustrating a method of processing a terminal housing according to an exemplary embodiment.

Fig. 1B is one of the schematic diagrams illustrating a glue grasping feature according to an exemplary embodiment.

Fig. 1C is a second schematic diagram illustrating a glue grasping feature according to an exemplary embodiment.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1A is a flow diagram illustrating a method of processing a terminal housing according to an exemplary embodiment, fig. 1B is one of schematic diagrams of a glue grasping feature illustrated according to an exemplary embodiment, and fig. 1C is a second of schematic diagrams of a glue grasping feature illustrated according to an exemplary embodiment; as shown in FIG. 1A, the in-mold forming glue grabbing method comprises the following steps S101-S102:

in step S101, a glue grasping feature that needs to be fixed on the metal shell is processed.

In an embodiment, during the processing of the plastic material, the processing manner may be determined according to the structural design of the product and the difficulty and cost of the processing process, for example, the plastic material may be processed into a glue-catching feature for in-mold molding of a metal in-mold body by stamping, die casting, Metal Injection Molding (MIM), and the like, and the glue-catching feature may be as shown in fig. 1B, and the glue-catching feature is an i-shaped structure including a plastic part 12 and a metal part 11, and the plastic part 12 and the metal part 11 are connected together, or, as shown in fig. 1C, the glue-catching feature is a dovetail inverted hook-shaped structure, and the plastic part 13 and the metal part 11 are connected together.

In step S102, the adhesive grasping feature is connected with the adhesive grasping structure on the metal shell to form the terminal shell.

In an embodiment, the connection manner of the adhesive grasping feature and the metal shell portion may be welding, dispensing, and the like, and the connection manner of the two is not limited in the present disclosure.

In this embodiment, need fix the gluey characteristic of grabbing on metal casing through independent processing to will grab gluey characteristic and become metal casing's independent part, avoid grabbing gluey characteristic and receive the holistic influence of former metal casing, because the selection of grabbing gluey characteristic's manufacturing process method and plastic material has the variety, thereby can save the cost, richen the design of metal mould internal forming structure.
