Conductor structures according to embodiments of the present application are described below in conjunction with fig. 1-9.

As shown in fig. 1-3, a conductor structure according to some embodiments of the present application, the conductor structure comprising: elastomer 1, copper foil composite sheet 2, first glue film 3 and second glue film 4.

The elastomer 1 has a first surface, a second surface and a first side surface, and the first surface is opposite to the second surface. The elastic body 1 has elasticity and can provide sufficient cushioning.

The first glue layer 3 is arranged on the first surface, and the second glue layer 4 is arranged on the second surface.

Copper foil composite piece 2 passes through first glue film 21 and second glue film 22 with 1 fixed connection of elastomer, copper foil composite piece 2 includes first portion 21, second portion 22 and connects first portion 21 with the third portion 23 of second portion 22, first portion 21 is range upon range of to be fixed in on the first glue film 3, first glue film 3 makes first portion 21 form the bonding fixed on the first surface. The second portion 22 is fixed to the second layer of glue 4 in a stacked manner, and the second layer of glue 4 forms an adhesive bond to the second portion 22 on the second surface. The third portion 23 is located on the side of the first side.

In this embodiment, the copper foil composite sheet 2 is attached to the first surface and then disposed onto the second surface around the first side. The copper foil composite sheet 2 comprises a copper foil layer formed by a copper foil material, the copper foil material has excellent electric conduction effect and heat conduction effect, and the elastomer 1 has a buffering effect. The copper foil composite sheet 2 wraps a part of the surface of the elastic body 1, so that the conductor structure has excellent electric conduction, heat conduction and buffering effects. Conductor structures are used for components within electronic devices to form a ground, heat conducting, and cushioning protective structure for the components. The first surface and the second surface which are opposite to each other are conducted through the copper foil composite sheet, so that the conductor structure can effectively improve the grounding and heat conducting effects on elements in the electronic equipment.

For example, the component is a camera 6 and the conductor structure is intended to be arranged between the bottom of the camera 6 and the housing 5 of the electronic device. The elastomer 1 enables the conductor structure to have a buffering effect and protects the camera 6 structure from being damaged.

The first part 21 is used for being connected with the bottom of the camera 6, the second part 22 is used for being connected with the shell 5 of the electronic equipment, and the copper foil composite sheet 2 conducts the bottom of the camera 6 with the shell 5 of the electronic equipment along the first surface, the first side face and the second surface in sequence. The copper foil composite sheet 2 forms a grounding and heat conducting path in the thickness direction in which the camera 6 is stacked with the conductor structure, i.e., forms a heat and heat conducting path in the Z direction of the electronic device, i.e., the thickness direction of the electronic device.

The conductive path formed by the copper foil composite sheet 2 makes the grounding path of the camera 6 shorter, and the heat conduction path formed by the copper foil composite sheet 2 makes the heat conduction path of the camera shorter. The conductor structure can effectively reduce the distance between the grounding path and the heat conduction path, thereby improving the heat dissipation effect and the grounding effect.

The second portion 22 is laminated to a surface of the second layer of glue 4, the second layer of glue 4 forming a connection between the second portion 22 and the second surface. The second portion 22 may cover a part of the second glue layer 4 or may cover the second glue layer 4 completely.

The second glue layer 4 may be a conductive glue layer, the second glue layer 4 having both the function of connecting the second portion 22 to the second surface and the function of conducting electricity. Under the condition that the second part 22 does not completely cover the second adhesive layer 4, the uncovered second adhesive layer 4 is connected with the shell 5, so that the path for conducting the second part 22 and the shell 5 is increased, and the conducting area of the copper foil composite sheet 2 and the shell 5 is increased.

Optionally, the second adhesive layer 4 is a conductive adhesive layer, the second portion 22 covers a part of the conductive adhesive layer 4, and another part of the conductive adhesive layer 4 not covered by the second portion 22 is used for forming a connection with an external structure.

The other part of the second adhesive layer 4 which is not covered by the second part 22 is connected with the shell 5, so that the path for conducting the second part 22 and the shell 5 is increased, and the conducting area of the copper foil composite sheet 2 and the shell 5 is increased.

The buffer effect of the elastic body 1 and the shorter heat conduction path and the electric conduction path of the copper foil composite sheet 2 enable one part of the conductor structure to simultaneously meet the requirements of buffering, grounding and heat dissipation. The operation procedures in the assembling and disassembling process are less and more convenient.

In one embodiment, as shown in fig. 2-6, the elastomeric body 1 further includes a second side opposite the first side.

The copper foil composite sheet 2 further comprises a fifth part 25 and a fourth part 24 for connecting the first part with the fifth part 25, the fourth part 24 is positioned on one side where the second side surface is positioned, and the fifth part 25 is fixed on the second adhesive layer 4 in a stacking mode.

In this embodiment, the copper foil composite sheet 2 forms two paths for heat conduction and electric conduction from both sides of the elastic body 1. One of the paths is: the element is in turn in communication with the housing 5 along a first section 21, a third section 23 and a second section 22. The other path is as follows: the element is in turn in communication with the housing 5 along the first, fourth and

fifth sections

21, 24, 25.

The component is, for example, a camera 6. The two paths enable the heat of the camera 6 to be led out to the shell 5 more quickly, so that the heat productivity of the camera 6 is reduced, and the heat dissipation effect is improved. The two paths enable the grounding effect of the camera 6 to be better, and the safety can be further improved.

The second portion 22 and the fifth portion 25 both cover the surface of the second glue layer 4, for example, the second portion 22 covers a part of the surface of the second glue layer 4, and the fifth portion 25 covers a part of the surface of the second glue layer 4.

The second and

fifth portions

22 and 25 are in electrical communication with the housing 5, and are capable of both making electrical connection for grounding and making electrical contact for heat dissipation.

Optionally, the second adhesive layer 4 covers the second surface, the second portion 22 covers a partial area of the second adhesive layer 4 close to the first side surface, and the fifth portion 25 covers a partial area of the second adhesive layer 4 close to the second side surface.

For example, there may be a spacing between the second portion 22 and the fifth portion 25, the uncovered portion of the second glue layer 4 being thermally or electrically conductive between the second portion 22 and the fifth portion 25 and conducting the second portion 22 and the fifth portion 25 with the housing 5 to increase a path of the second portion 22 and the fifth portion 25 with the housing 5 through the uncovered second glue layer 4.

In one embodiment, as shown in fig. 7-9, the second adhesive layer 4 extends from the second surface toward the second side surface, the fifth portion 25 is fixed to the portion of the second adhesive layer 4 extending from the second surface in a stacked manner, and the second portion 22 extends from the second surface toward the second side surface.

In this embodiment, the second portion 22 is in communication with the housing 5 within the second surface and extending beyond the second surface, increasing the area of communication between the copper foil composite sheet 2 and the housing 5.

The fifth part 25 and the part of the second adhesive layer 4 extending out of the second surface are conducted with the shell 5 outside the second surface, so that the conducting area of the copper foil composite sheet 2 and the shell 5 is increased.

As shown in fig. 9, the camera 6 is taken as an example of the device. At the bottom of the camera 6, it is in communication with the first part 21, via the third part 23 to the second part 22. The second part 22 is in communication with the part of the housing 5 opposite to the bottom of the camera 6 and extends to the side of the second side face, so that the contact area of the second part to the housing 5 is increased.

And the first section 21 is conducted via the fourth section 24 to the fifth section 25. The fifth part 25 is stacked on the part of the second adhesive layer 4 extending out of the second surface, and the second adhesive layer 4 extending out of the second surface is conducted with the shell 5 outside the range of the elastic body 1, so that the contact area of the shell 5 is increased.

The range of conduction of the copper foil composite sheet 2 and the shell 5 is increased by the second part 22, the second adhesive layer 4 and the fifth part 25 extending out of the elastic body 1 and extending out of the elastic body 1, so that heat can be conducted to a position farther away from the camera 6 along the copper foil composite sheet 2, and the heat dissipation effect is improved.

Optionally, the fifth portion 25 extends beyond the second layer of glue 4.

The fifth portion 25 protruding from the second glue layer 4 may be in direct communication with the housing 5. The copper foil composite sheet 2 has higher electric and thermal conductivity compared with the second adhesive layer 4, and can enable a conduction path from the first portion 21 to the shell 5 through the fourth portion 24 and the fifth portion 25 in sequence to have higher heat dissipation and grounding effects.

Optionally, the second portion 22 covers a partial area of the second glue layer 4.

The second portion 22 is in contact with the housing 5 and the second layer of glue 4 not covered by the second portion 22 forms an adhesive bond on the housing 5. The second adhesive layer 4 is bonded with the shell 5, so that the contact firmness degree of the second part 22 and the shell 5 is improved, the contact firmness degree of the fifth part 25 and the shell 5 is improved, and the reliability of the conduction structure of the copper foil composite sheet 2 and the shell 5 is effectively improved.

In one embodiment, as shown in fig. 2, 5, and 8, the first adhesive layer 3 includes a first adhesive layer 31 and a second adhesive layer 32, a PET sheet 33(polyethylene terephthalate) is disposed between the first adhesive layer 31 and the second adhesive layer 32, and the first adhesive layer 31, the second adhesive layer 32, and the PET sheet 33 are stacked.

In this embodiment the first layer of insulating glue 31 forms a bond with the first portion 21 and the second layer of insulating glue 32 forms a bond with the first surface. The PET sheet 33 provides a supporting function to the first glue layer 3 so that the first glue layer 3 can maintain an unfolded state. The first part 21 is bonded with the first glue layer 3, the unfolded state can be kept, the effective contact area of the first part 21 and the camera 6 is kept, and the heat conduction and electric conduction capabilities are improved.

The bonding face that first glue film 3 formed between first portion 21 and first surface is level and smooth, can not influence the roughness of copper foil composite sheet 2, has improved the area of copper foil composite sheet 2 and the contact of 6 bottoms of camera.

In one embodiment, the copper foil composite sheet 2 includes a copper foil layer and a Polyimide layer (PI Film) laminated with the Polyimide layer, the Polyimide layer facing the elastic body 1 side.

The polyimide layer serves as a support structure for the copper foil composite sheet 2 and is located against the elastomer 1 to provide sufficient structural strength to the copper foil composite sheet 2 to support the copper foil layer. The copper foil layer on the outside, away from the elastomer 1, provides a complete electrical conduction path and a heat dissipation path for components within the electronic device.

In one embodiment, the elastic body 1 comprises conductive foam.

The conductive foam has elasticity and enough structural strength. Under the condition of buffering elements in the electronic equipment, overlarge deformation cannot occur, the copper foil composite sheet 2 can be effectively kept in contact conduction with the elements and the shell 5, and the stability of a conductor structure is guaranteed. For example, the component is the camera 6, and the elastomer 1 provides effective buffering for the camera 6 through the conductive foam, so that excessive deformation is not formed in the process of buffering the camera 6, and the copper foil composite sheet 2 is effectively kept to be conducted between the camera 6 and the shell 5.

In an embodiment, there is provided an electronic device comprising a conductor structure as described in any of the above.

The conductor structure in the electronic equipment has better heat conduction and electric conduction effects, and meets three requirements of grounding, heat dissipation and buffering of elements through the conductor structure.

In one embodiment, as shown in fig. 3, 6, and 9, the electronic device further includes a housing 5 and a camera 6, the housing 5 forms a receiving cavity, the camera 6 is located in the receiving cavity, the first portion 21 is connected to a bottom of the camera 6, and the second portion 22 abuts against the housing 5.

In this embodiment, the conductor structure provides a conduction path in the thickness direction of the electronic apparatus, making the grounding and heat dissipation paths of the camera 6 shorter, improving the grounding and heat dissipation effects. When the conductor structure has a Z-direction conduction path in the thickness direction of the electronic device, that is, in the Z direction of the electronic device, the heat of the camera 6 can be quickly conducted to the housing 5, thereby reducing the heat accumulation of the camera 6. And a shorter conduction path leads to a better grounding effect.
