Description

Shell and electronics

Technical field

The utility model relates to a kind of shell and with the electronics of the shell.

Background technique

Currently, there is more and more electronics using metal material as shell.Metal shell have can While the advantages of enhancing the structural strength of electronics, but have the defects that shield electromagnetic wave, and then it is logical to influence electronics Interrogate equipment receiving and transmitting signal.

To solve the above problems, keeping metal shell corresponding with the antenna of electronics when manufacturing metal shell Position open up hollow-out parts, then, by spray Shooting Technique, to hollow-out parts fill nonmetallic materials, for example, filling plastic cement. The nonmetallic materials will not generate shielding action to electromagnetic wave, and then improve the ability of the receiving and transmitting signal of electronics.

However, metal shell in the prior art but has following defects that after injection Shooting Technique molding

Nonmetallic materials, e.g., plastic cement can generate retraction after the cooling period, this produces the junction of plastic cement and metal shell Raw crackle, not only influences the appearance of the metal shell after injection molding, and influences the bonding strength between plastic cement and metal shell.

Utility model content

For the above-mentioned technical problems in the prior art, the embodiments of the present invention provide a kind of shell.

In order to solve the above technical problems, the embodiments of the present invention the technical solution adopted is that:

A kind of shell is applied to electronics, shell position corresponding with the antenna of the electronics It sets and offers hollow-out parts, the shell is formed with stop configurations along the edge of the hollow-out parts, and the stop configurations are for limiting The plastic cement that system fills the hollow-out parts bounces back after the cooling period.

Preferably, the stop configurations are the stopping dam being arranged along the edge of the hollow-out parts, are opened up on the stopping dam There is the deflector hole flowed for plastic cement in injection.

Preferably, the edge that the shell is located at the hollow-out parts is provided with deep gouge, and the stopping dam is set to described At the slot bottom of deep gouge, the upper end of the stopping dam is lower than the notch of the deep gouge.

The invention also discloses a kind of electronics, including functional hardware, further include above-mentioned shell, described Shell surrounds the functional hardware, and the hollow-out parts of the shell are corresponding with the aerial position in the functional hardware.

Compared with prior art, the shell of the utility model and the beneficial effect of electronics are: the utility model Stop configurations are set by the edge of the hollow-out parts in shell, plastic cement can effectively be avoided to generate in the curing process with shell Crackle, and then the bonding strength of plastic cement and shell is improved, improve presentation quality of the shell at hollow-out parts.

Specific embodiment

It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model Mode is applied to elaborate to the utility model.

As shown in Figure 1, the embodiments of the present invention disclose a kind of shell 100, the main body of the shell 100 is by metal Material is made, which can be the shell 100 of the electronics such as mobile phone, tablet computer, but not limited to this.Such as Fig. 2 To shown in Fig. 4, the shell 100 of metal position corresponding with antenna (component for carrying out receiving and transmitting signal) offers hollow-out parts 10, The hollow-out parts 10 are filled with plastic cement 40, which is filled in hollow-out parts 10 using sprayup process.In the utility model In, shell 100 is formed with stop configurations along the edge of hollow-out parts 10, and stop configurations are used to limit the plastic cement of filling hollow-out parts 10 40 bounce back after the cooling period.Specifically, deep gouge 30 is offered in the edge that shell 100 is located at hollow-out parts 10, until stop configurations Blend stop 20, which is set to the slot bottom of deep gouge 30, and stopping dam 20 is not higher than deep gouge 30, so that stopping dam 20 is non-bulging In the outer surface of shell 100, deflector hole 21 is offered on stopping dam 20, which is used for when carrying out injection molding, Uncured plastic cement 40 outside stopping dam 20 and in stopping dam 20 is able to carry out flowing.

The advantage of above-mentioned shell 100 disclosed in the utility model is:

When carrying out injection molding, the space in space and stopping dam 20 outside stopping dam 20 is filled by plastic cement 40, and By the guide functions of deflector hole 21, so that smooth inside and outside plastic cement 40.During plastic cement 40 is cured, stopping dam 20 Plastic cement 40 is limited to central reduction, so that the junction of plastic cement 40 and shell 100, which will not generate, to be split in 40 solidification process of plastic cement Line, and then the bonding strength of plastic cement 40 Yu shell 100 is improved, improve appearance of the shell 100 at hollow-out parts 10.

Stop configurations are arranged by the edge of the hollow-out parts 10 in shell 100 in the utility model, can effectively avoid moulding Glue 40 is cracked with shell 100 in the curing process, and then improves the bonding strength of plastic cement 40 Yu shell 100, is improved Presentation quality of the shell 100 at hollow-out parts 10.

The invention also discloses a kind of electronics, which includes functional hardware and above-mentioned Shell 100, shell 100 surround functional hardware, and the plastic cement 40 for being filled in the hollow-out parts 10 of shell 100 and the day in functional hardware Line position is corresponding, so that antenna can obtain the ability of preferable receiving and transmitting signal.

Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new In the protection scope of type.
