Slit 121.In addition, further including the conductive layer 122 separated by slit 121, that is, slit 121 in the second cut portion 120
With conductive layer 122 it is alternating with each other formed.Three slits 121, the disclosure are formd although schematically showing in Fig. 5
It is without being limited thereto, the quantity of slit can be changed as needed.As shown in fig. 6, from the point of view of the outer surface direction of conductive shell 1000,
When cutting the second cut portion 120, part clout can be retained in the outer surface of conductive shell 1000.It is embodied in Fig. 6, slit
121 do not penetrate the outer surface of conductive shell 1000.The structure will be described in detail in figures 7 and 8 later.
Fig. 5 is referred again to, from the point of view of the inner surface direction of conductive shell 1000, is formd not in the first cut portion 110
Removed conductive connection part 111, to connect the first conductive part 200 and the second conductive part 300.Referring to Fig. 6, from conductive shell
From the point of view of 1000 outer surface direction, a plurality of slit 112 is formd in the first cut portion 110.Although in Fig. 6 schematically
It shows and forms three slits 112, but the present disclosure is not limited thereto, can change the quantity of slit as needed.In addition,
It further include the conductive layer 113 separated by slit 112, that is, slit 112 and conductive layer 113 are alternating with each other in one cut portion 110
Ground is formed.
According to the disclosure, the quantity of the slit of the first cut portion 110 and the second cut portion 120 can be identical.In addition, the
The slit of one cut portion 110 can be located on same cut surface with the slit of the second cut portion 120 respectively.That is, the
The slit of one cut portion 110 can communicate with each other respectively with the slit of the second cut portion 120 and be located on the same line, thus
From the point of view of the outer surface of conductive shell, the slit of the first cut portion 110 is respectively one with the slit of the second cut portion 120
Seam.
In addition, the slit width of the first cut portion 110 and the slit in the second cut portion 120 can be each other according to the disclosure
It is identical, for example, can correspond to the thickness of the blade of cutting tool 2000.According to the disclosure, the slit width of slit can be 0.03mm
~0.5mm, preferably 0.03mm~0.15mm.In view of the aesthetic appearance of conductive shell, the narrower the slit width of slit the better
Fig. 7 is the schematic diagram for showing the conductive shell of A-A ' the line interception along Fig. 4, and Fig. 8 is the right side for showing the shell in Fig. 7
View.Hereinafter with reference to Fig. 7 and Fig. 8, the part clout 123 of the second cut portion 120 is described.
As shown in fig. 7, when cutting the slit of the second cut portion 120, in the outer surface reserve part of conductive shell 1000
Divide clout 123.The part clout 123 can avoid housing distortion in the injection step that will be described later.Preferably, more than part
The thickness d of material 123 is (as shown in Figure 8) to be more than or equal to 1.0mm.
Optionally, part clout 123 can not be retained, but the second cut portion 120 is fully penetrated, so that the second cutting
Slit 121 in part 120 runs through the inner surface and the outer surface of conductive shell 1000.
It, in step s 30, can be to slit and conductive shell after forming a plurality of slit 121 and 112 according to above step
The inner-cavity structure of body 1000 is molded simultaneously.Fig. 9 is the inner surface for showing the conductive shell after being molded to slit
Schematic diagram.
The inner-cavity structure that conductive shell 1000 can be processed before injection molding, however, the present disclosure is not limited thereto.As shown in figure 9,
By being molded to slit, non-conducting material can be filled in slit to form non-conductive layer 124.By to conductive shell
1000 inner-cavity structure is molded, and reinforcement structure and connection structure etc. can be formed.
From the point of view of the inner surface of conductive shell, conductive layer 122 and non-conductive layer 124 are alternately laminated in the second cutting region
In 120.Preferably, the width of each non-conductive layer can be 0.03mm~0.5mm (equal with the width of slit).It is each non-conductive
The width of layer 124 can be identical, and the width of the width and non-conductive layer 124 of conductive layer 122 may be the same or different, here, width
Refer to the width of a conductive layer 122 or a non-conductive layer 124 on 200 to the second conductive part of the first conductive part, 300 direction.
Since conductive layer 122 is formed by the conductive shell 1000 not cut, the material of conductive layer 122 can with lead
The material of electric shell 1000 is identical.Non-conductive layer 124 may include plastics.
In addition, conductive connection part 111 can also be electrically connected other than being electrically connected the first conductive part 200 and the second conductive part 300
It is connected to conductive layer 122.
As described in the background technology part of the disclosure, by the first method of the prior art, although can be micro- in cutting
Retain non-cut portion as conductive connection part in the inside of shell when seam, but need to be molded twice, process is tedious, system
Make at high cost.By the second method of the prior art, although only the non-gold of a plurality of slit can be completed by once injection molding
Belong to material filling and the injection molding of housing cavity structure, but since conductive connection part can not be retained on an interior surface of the housing, because
This needs to connect two current-carrying parts by the other conductive connection part of rivet or weld.This result in the need for additional riveting or
Welding procedure, and the fixation of shell and slit band during rivet or weld after cutting are also extremely difficult, therefore not
Only complex process, and likely result in shell and deformed in injection moulding process.
However, following effect can be achieved at the same time according to the disclosure: only can complete a plurality of slit by once injection molding
Nonmetallic materials filling and the injection molding of housing cavity structure, while can retain when cutting slit in the inside of conductive shell and lead
Electrical connection section (111 in Fig. 5 and Fig. 9) is without additional rivet or weld technique.Therefore, according to the disclosure, system can be simplified
Process is made, the reliability of product is improved.
As described above, part clout 123 (as shown in Figures 7 and 8) can be retained when cutting the second cut portion 120,
The part clout 123 can guarantee that conductive shell is indeformable during injection molding.
After completing injection molding, part clout 123 can be removed when processing appearance (outer surface) of conductive shell 1000.
For example, can be switched at arrow locations shown in fig. 8 in following process, to remove part clout 123.But the disclosure is not
It is limited to this, as long as guaranteeing removal part clout 123.
From the above description, it can be seen that can also infused even if retaining part clout 123 when cutting the second cut portion 120
(technique necessary to manufacture handset shell, for example, cutting camera aperture) cut-out in the process is processed in appearance after the completion of modeling
Clout 123.That is, even if in order to prevent conductive shell in injection moulding process modification and retain part clout 123, can also be
Cut-out clout 123 in appearance process, without carrying out quadric injection mould to slit or inner-cavity structure.
