Description
Technical Field
The invention relates to the technical field of terminal equipment, in particular to a conductive device and terminal equipment.
Background
As consumer demands become higher and higher, the functions of the terminal device become more and more, and some data function modules (such as camera modules and the like) of the terminal device operate to transmit larger and larger data. These data function modules generate more and more high-frequency noise in the process of transmitting data. Considering the higher integration of terminal devices, more data functional modules are usually located near the antenna clearance area. In the data transmission process, the data function module located in the antenna clearance area increasingly interferes with the communication sensitivity of the terminal equipment.
Analysis shows that the FPC radiation of the data function module for connecting the mainboard is strong, and in order to reduce the influence of radiation on communication sensitivity, more and more data function modules of the terminal equipment are connected to the grounding area of the mainboard through conductive foam, so that electromagnetic noise radiation is inhibited.
The adoption of the conductive foam for grounding has the advantages of flexible use, small required space, convenient assembly and the like. When the conductive foam is grounded, the data function module needs to apply enough pre-pressing on the conductive foam to enable the conductive foam to have smaller on-resistance and achieve better grounding effect. However, the data function module is usually a precision electronic component, and the data function module may also be subjected to the pressure of the conductive foam due to the large pre-pressure, which may cause the data function module to deform and operate abnormally. For example, in the case where the data function module is a display module, a display abnormality occurs in the display module. In the case where the data function module is a camera module, the imaging quality of the camera module may be deteriorated.
Certainly, the data function module is not limited, and the other two function modules inside the terminal device are electrically connected by using the pre-pressed conductive foam.
Disclosure of Invention
The invention discloses a terminal device, which aims to solve the problem that the two functional modules in the conventional terminal device are electrically connected by prepressed conductive foam, so that the deformation is easily caused and the abnormal work is caused.
In order to solve the problems, the invention adopts the following technical scheme:
a conductive device comprises a first conductive adhesive layer, a second conductive adhesive layer and at least two elastic conductive units arranged between the first conductive adhesive layer and the second conductive adhesive layer, wherein each elastic conductive unit is electrically connected with the first conductive adhesive layer and the second conductive adhesive layer, and an elastic deformation gap is reserved between every two adjacent elastic conductive units.
A terminal device comprises a first functional module, a second functional module and the conducting device, wherein the conducting device is arranged between the first functional module and the second functional module, the first functional module is bonded with a first conducting adhesive layer and is electrically connected with the first conducting adhesive layer, and the second functional module is bonded with a second conducting adhesive layer and is electrically connected with the second conducting adhesive layer.
The technical scheme adopted by the invention can achieve the following beneficial effects:
the conductive device disclosed by the invention can be applied to terminal equipment and is connected between a first functional module and a second functional module of the terminal equipment, and in the specific connection process, the first conductive adhesive layer can be bonded and electrically connected with the first functional module; the second conductive adhesive layer can be bonded with and electrically connected with the second functional module. The elastic conductive unit arranged between the first conductive adhesive layer and the second conductive adhesive layer can realize the electric connection between the first conductive adhesive layer and the second conductive adhesive layer, and finally can realize the electric connection between the first functional module and the second functional module. Because the elastic deformation gap can be formed between two adjacent elastic conductive units, the elastic conductive units can not apply larger rebound force to the first functional module and the second functional module when the whole conductive device is pressed on the premise of ensuring the elasticity of the whole conductive device, and further the first functional module or the second functional module can be prevented from being damaged.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1-2, an embodiment of the invention discloses a conductive device 100, the disclosed conductive device 100 can be applied to a terminal device, and the disclosed conductive device 100 includes a first conductive adhesive layer 110, a second conductive adhesive layer 120, and at least two elastic conductive units 130.
The first conductive adhesive layer 110 and the second conductive adhesive layer 120 are both adhesive layers capable of conducting electricity, the at least two elastic conductive units 130 are arranged between the first conductive adhesive layer 110 and the second conductive adhesive layer 120, each elastic conductive unit 130 is respectively bonded with the first conductive adhesive layer 110 and the second conductive adhesive layer 120, and meanwhile, each elastic conductive unit 130 is respectively electrically connected with the first conductive adhesive layer 110 and the second conductive adhesive layer 120.
An elastic deformation gap 140 is left between two adjacent elastic conductive units 130, and the elastic deformation gap 140 is a gap structure, which undoubtedly enables the whole conductive device to have better elasticity, and at the same time, reduces the elastic resistance of the elastic conductive units 130. In a more preferable scheme, an elastic deformation gap 140 is left between any two adjacent elastic conductive units 130.
The conductive device 100 disclosed in the embodiment of the present invention can be applied to a terminal device and connected between a first functional module 200 and a second functional module 300 of the terminal device, and in a specific connection process, the first conductive adhesive layer 110 can be bonded and electrically connected with the first functional module 200; the second conductive adhesive layer 120 may be adhered to and electrically connected to the second functional module 300. The elastic conductive unit 130 disposed between the first conductive adhesive layer 110 and the second conductive adhesive layer 120 can achieve electrical connection between the first conductive adhesive layer 110 and the second conductive adhesive layer 120, and finally can achieve electrical connection between the first functional module 200 and the second functional module 300. Because the elastic deformation gap 140 can be formed between two adjacent elastic conductive units 130, the elastic conductive units 130 do not apply a large rebound force to the first functional module 200 and the second functional module 300 when the whole conductive device 100 is pressed on the premise of ensuring the elasticity of the whole conductive device 100, and further the first functional module 200 or the second functional module 300 can be prevented from being damaged.
One of the first functional module 200 and the second functional module 300 may be a data functional module, and the other may be a main board of the terminal device. Of course, the first functional module 200 and the second functional module 300 may also be two other devices in the terminal equipment that need to be elastically electrically connected through the conductive device 100, and the embodiment of the present invention does not limit the specific kinds of the first functional module 200 and the second functional module 300.
The elastic conductive unit 130 may adopt various structures with good elasticity, and referring to fig. 1 and fig. 2 again, the embodiment of the present invention discloses an elastic conductive unit 130 with a specific structure, and the disclosed elastic conductive unit 130 includes a first supporting portion 131, a second supporting portion 132 and a flexible filler 133.
The first supporting portions 131 and the second supporting portions 132 are distributed at intervals, two ends of each of the first supporting portions 131 and the second supporting portions 132 are respectively connected with the first conductive adhesive layer 110 and the second conductive adhesive layer 120, the first supporting portions 131, the second supporting portions 132, the first conductive adhesive layers 110 and the second conductive adhesive layers 120 of the elastic conductive units 130 form filling spaces, the flexible fillers 133 are filled in the filling spaces, and the flexible fillers 133 are electrically connected with the first conductive adhesive layers 110 and the second conductive adhesive layers 120. In this structure, the flexible filler 133 is an electrical connection structure, so that electrical connection between the first conductive adhesive layer 110 and the second conductive adhesive layer 120 can be achieved. The flexible filler 133 can have a weak support and a certain elasticity, so that the first and second support portions 131 and 132 function to support the entire structure of the conductive device 100.
In a preferred embodiment, the flexible filler 133 may be made of a material whose elastic force does not change significantly with further increase of the deformation amount when the deformation amount reaches a preset value. The type of the flexible filler 133 can be varied, and in a specific embodiment, the flexible filler 133 can include a flexible body and a conductive layer disposed on the flexible body. The flexible body may be a bubble fleece or a sponge. The embodiment of the invention does not limit the specific material of the flexible main body.
In a more preferable aspect, each of the first and second supporting portions 131 and 132 may be a brittle layer that is broken when a pressure greater than a preset pressure is applied thereto. Referring to fig. 2, in a specific use process, the second conductive adhesive layer 120 of the conductive device 100 is bonded to the second functional module 300, the first functional module 200 is pressed against the conductive device 100, so that the first functional module 200 is bonded to the first conductive adhesive layer 110 of the conductive device 100, and as the pressing continues, the first supporting portion 131 and the second supporting portion 132 are broken, so that the supporting force of the first supporting portion 131 and the second supporting portion 132 disappears, the pressure (i.e., the bounce force of the conductive device 100) of the conductive device 100 on the first functional module 200 and the second functional module 300 is reduced, and due to the bonding of the first conductive adhesive layer 110 and the second conductive adhesive layer 120, the conductive device 100 can be ensured to be electrically connected to the first functional module 200 and the second functional module 300, and meanwhile, the first functional module 200 and the second functional module 300 are not damaged.
In the embodiment of the present invention, the fragile layer refers to a structural member that can be broken when subjected to a pressure exceeding a preset pressure. Specifically, the preset pressure may be 6N.
In a preferred embodiment, the first supporting portion 131 and the second supporting portion 132 may be both arc-shaped supporting portions, and the first supporting portion 131 and the second supporting portion 132 are both recessed toward a direction in which they approach each other. In this case, the elastic deformation gap 140 formed between two adjacent conductive devices 100 can be made larger, which is more beneficial to reducing the bounce generated by the conductive devices 100 in a pressed state, and thus the damage to the first functional module 200 and the second functional module 300 can be further reduced.
In order to make the supporting of the conductive device 100 more uniform, in a preferable scheme, the distance between each two adjacent elastic conductive units 130 can be equal.
