One side surface of the display screen 100 is used to display image information, and the side surface of the display screen 100 is generally defined as a front surface thereof, and the other side surface opposite to the front surface thereof is a rear surface thereof. The case 200 is disposed around the periphery and the back of the display screen 100, and is used for supporting and fixing the display screen 100 and providing protection. The front surface of the display screen 100 is exposed outside the housing 200 for a user to view contents displayed by the display screen 100 or to perform input operations to the electronic device 10.

Fig. 2 is an exploded structural view of the electronic device shown in fig. 1. Referring to fig. 2, when the electronic device 10 is a bar-type electronic device, the case 200 of the electronic device 10 may include a center frame 210 and a rear cover 220, the center frame 210 being connected between the display screen 100 and the rear cover 220, the display screen 100 being supported at one side surface of the center frame 210, and the rear cover 220 being connected at the other side surface of the center frame 210.

The display screen 100 is generally integrally mounted on the middle frame 210, so as to ensure the strength and stability of the display screen 100, and meet the use requirement of the display screen 100. The rear cover 220 is generally connected to the middle frame 210 in a lap joint manner, and the middle frame 210 and the rear cover 220 together enclose a housing cavity, in which devices such as the motherboard 300, the battery 400, the camera 500, a speaker (not shown in the figure) and the like are mounted.

The middle frame 210 may include a middle plate portion 211 and a rim portion 212, the middle plate portion 211 being positioned between the display screen 100 and the rear cover 220, the rim portion 212 being surrounded on a peripheral side of the middle plate portion 211. For example, the rim portion 212 may extend perpendicularly to the plate surface of the middle plate portion 211 toward both sides of the middle plate portion 211. Illustratively, the rim portion 212 and the middle plate portion 211 may be an integrally formed structure.

The display 100 is generally attached to the middle plate 211 of the middle frame 210 by an integrally attaching method. By virtue of the support of the middle plate 211 to the display screen 100, the display screen 100 can be supported stably and firmly, so that the display screen 100 has enough strength and meets the use requirement that the display screen 100 is pressed frequently. The frame 212 is disposed around the display screen 100 to protect the side of the display screen 100, so as to help the display screen 100 to resist collision, drop and other risk scenes and protect the display screen 100 from damage.

The edge of the rear cover 220 is connected to the rim portion 212 of the middle frame 210, for example, the edge of the rear cover 220 is bonded to the rim portion 212. A space is provided between the middle plate portion 211 of the middle frame 210 and the rear cover 220, and the space forms a receiving cavity as described above to mount devices in the receiving cavity between the middle plate portion 211 of the middle frame 210 and the rear cover 220.

For example, at least a portion of the structure of the middle frame 210 may be made of a metal material. For example, the frame portion 212 of the middle frame 210 is a metal frame, the edge region where the middle plate portion 211 of the middle frame 210 is connected to the frame portion 212 may be made of a metal material, and other regions of the middle plate portion 211 may be made of a plastic material integrally injection molded. The metal part of the middle frame 210 can be used as an antenna to realize the receiving and transmitting of radio frequency signals by the electronic equipment.

In the electronic device 10, electrical connections are required between some of the components and structures. For example, the copper foil in the display 100 is electrically connected to the middle frame 210, the driving device in the camera 500 is electrically connected to the motherboard 300, and the metal ring on the back cover 220 (for making the light enter the edge of the light hole of the camera 500 to enclose) is electrically connected to the motherboard 300 or other circuit boards.

In the related art, the electrical connection between the devices and the structural members is generally realized through metal shrapnel, and the metal shrapnel is in elastic contact with the devices and the structural members to form an electrical connection structure together. For example, the copper foil in the display 100 and the metal portion of the middle frame 210 are electrically connected by a metal dome. The housing 200 of the driving device in the camera 500 is configured as a metal housing, and a metal dome is connected between the housing 200 of the driving device and the main board 300. The metal ring on the back cover 220 may also be electrically connected to the motherboard 300 or other circuit board in the electronic device 10 through metal spring.

However, contact between the metal spring and these devices and structures creates a potential difference in the electrical connection structure. When external liquid enters the electronic device 10 or there is a leak of liquid inside the electronic device 10, the electrical connection structure is placed in a saline environment. At this time, the salt solution forms an electron path and an ion path in the electric connection structure under the action of the potential difference in the electric connection structure, so that the electric connection structure is subjected to galvanic corrosion.

When the corrosion degree is serious, the reliability of the metal elastic sheet can be affected, the elastic contact between the metal elastic sheet and the corresponding device and the structural member is invalid, and the electric connection structure is broken. And, structural strength of the device and the structural member is also affected, for example, rigidity of the middle frame 210 is reduced due to corrosion, and reliability of the whole electronic device 10 is affected. In addition, corrosives generated by corrosion reaction can be accumulated in the electric connection structure, devices such as a circuit board in the electric connection structure can be jacked up, the dimensional stability of the circuit board is affected, and the problem of board-level failure such as connection failure and device short circuit is possibly caused.

In view of this, the embodiment of the present application improves the manner of electrically connecting the structural members in the electronic device 10, by designing the electrical connector for electrically connecting the two structural members, providing the polymer elastomer as the main body supporting structure of the electrical connector, and by dispersing the conductive filler in the local area of the polymer elastomer, the conductive filler is arranged in an orientation along the height direction of the polymer elastomer and occupies the height space of the polymer elastomer completely. In this way, it is possible to form the conductive path in the polymer elastomer, the conductive path extending in the height direction of the polymer elastomer and extending to both side surfaces in the height direction of the polymer elastomer. Thus, the polymer elastomer is elastically contacted with the structural members positioned at the two sides of the height direction of the polymer elastomer to form an electric connection assembly, and the conductive channels in the polymer elastomer electrically connect the structural members at the two sides. So set up, the polymer elastomer is isolated outside the electrically conductive bullet of electric connection subassembly with the salt solution and is connected the region, prevents to form electron passageway and ion passageway in electric connection subassembly, improves and avoids the galvanic corrosion phenomenon even, promotes electric connection subassembly's connection reliability, guarantees structural strength and dimensional stability of structure, promotes electronic equipment's reliability.

In the following, an electrical connection assembly formed by two structural members to be electrically connected, and an electrical connector for electrically connecting the two structural members in the electrical connection assembly are described in detail in the electronic device 10 according to the embodiment of the present application.

Fig. 3 is a schematic structural diagram of an electrical connection assembly according to an embodiment of the present application. Fig. 4 is an exploded view of the electrical connection assembly of fig. 3. Fig. 5 is a cross-sectional view of the electrical connection assembly of fig. 3 taken along line A-A.

Referring to fig. 3, an electrical connection assembly 600 in an electronic device 10 is illustrated. As the name suggests, the electrical connection assembly 600 is assembled by connecting two structural members that need to be electrically connected together by an electrical connector 630.

The electrical connection assembly 600 may include a first structural member 610, a second structural member 620, and an electrical connector 630, where the first structural member 610 and the second structural member 620 are two structural members of the electronic device 10 that need to be electrically connected, and the electrical connector 630 is disposed between the first structural member 610 and the second structural member 620. The electrical connector 630 is an electrically conductive structure, and the first structural member 610 and the second structural member 620 are electrically connected by the electrical connector 630, or the electrical connector 630 electrically connects the first structural member 610 and the second structural member 620.

Illustratively, the first structural member 610 and the second structural member 620 may be copper foil in the display 100, the middle frame 210, the housing 200 of the driving device in the camera 500, a metal ring on the rear cover 220, and the like as described above. For example, the first structural member 610 and the second structural member 620 may each be a metallic member to electrically communicate the two metallic members through the electrical connection 630. Or one of the first structure 610 and the second structure 620 may be a metal piece and the other may be a circuit board (e.g., motherboard 300 or other circuit board in electronic device 10) to electrically communicate the metal piece with the circuit board via electrical connection 630. Alternatively, the first structural member 610 and the second structural member 620 may be circuit boards, so as to electrically connect the two circuit boards through the electrical connector 630. This embodiment is not particularly limited.

It should be understood that, the first structural member 610 (or the second structural member 620) is a metal member, and does not limit that a certain structural member of the electronic device 10 that needs to be electrically connected is entirely made of metal, but refers to that a portion of the structural member that needs to be electrically connected is made of a metal structure. Taking the case 200 of the driving device in the camera 500 or the metal ring on the rear cover 220 as a structural member to be electrically connected as an example, the first structural member 610 (or the second structural member 620) may refer to the entire case 200 or the metal ring of the driving device as a whole. Taking the middle frame 210 as an example of a structural member that needs to be electrically connected, the first structural member 610 (or the second structural member 620) may refer to a metal portion in the middle frame 210, for example, the first structural member 610 (or the second structural member 620) is the frame portion 212 of the middle frame 210.

Referring to fig. 4 and 5, the first and second structural members 610 and 620 may be disposed at both sides of the electric connector 630 in the height direction, one side surface of the electric connector 630 in the height direction is in contact with the first structural member 610, and the other side surface of the electric connector 630 in the height direction is in contact with the second structural member 620 to electrically conduct the first and second structural members 610 and 620 through the electric connector 630. The height direction of the electrical connector 630 is, for example, a thickness direction of the electrical connector 630.

In this embodiment, the main structure of the electrical connector 630 is a polymer elastomer 631, the first structural member 610 and the second structural member 620 are respectively located at two sides of the polymer elastomer 631 in the height direction, and the polymer elastomer 631 is supported between the first structural member 610 and the second structural member 620. The first structural member 610 is in contact with one side surface of the polymer elastic body 631 in the height direction, and the second structural member 620 is in contact with the other side surface of the polymer elastic body 631 in the height direction.

The polymer elastomer 631 incorporates a conductive filler 632, the conductive filler 632 being dispersed in a localized region of the polymer elastomer 631, the conductive filler 632 forming a conductive channel 6301 (shown in phantom in fig. 5) within the polymer elastomer 631. Wherein, the conductive filler 632 may be distributed along the height direction of the polymer elastomer 631, and the conductive filler 632 occupies the entire height space of the polymer elastomer 631. As such, the conductive channels 6301 formed in the polymer elastomer 631 by the conductive filler 632 may extend in the height direction of the polymer elastomer 631, and the conductive channels 6301 extend to both side surfaces of the polymer elastomer 631.

So configured, the polymer elastomer 631 has good elasticity as a main body supporting structure of the electric connector 630. By making the two side surfaces of the polymer elastomer 631 in the height direction respectively spring-connect with the first structural member 610 and the second structural member 620, the two sides of the polymer elastomer 631 generate certain elastic deformation, so that the first structural member 610 and the polymer elastomer 631, and the second structural member 620 and the polymer elastomer 631 can be ensured to be in close contact.

Further, by adding the conductive filler 632 to the polymer elastomer 631, the conductive filler 632 is densely distributed in the height direction of the polymer elastomer 631 and occupies the entire height space of the polymer elastomer 631. The conductive fillers 632 are in electrical contact with each other, and conductive channels 6301 extending to both side surfaces in the height direction are formed in the polymer elastomer 631. The first structural member 610 is in electrical contact with one end of the conductive channel 6301 in the polymer elastomer 631 and the second structural member 620 is in electrical contact with the other end of the conductive channel 6301 in the polymer elastomer 631 to make electrical connection between the first structural member 610 and the second structural member 620 through the conductive channel 6301 in the polymer elastomer 631.

That is, the first structural member 610 and the second structural member 620 disposed at both sides of the height direction of the polymer elastic body 631 are electrically and elastically connected to the polymer elastic body 631 through the electrically conductive path 6301 in the polymer elastic body 631. The conductive channels 6301 are respectively conductive spring-connected regions of the electrical connector 630 and the first structural member 610, and the electrical connector 630 and the second structural member 620 in the regions of the two side surfaces of the polymer elastomer 631 in the height direction.

Since the conductive path 6301 is formed inside the polymer elastomer 631, the polymer elastomer 631 can protect the conductive filler 632 in the conductive path 6301. The polymer elastomer 631 provides good insulation to isolate the saline solution from the conductive spring contact areas of the electrical connection assembly 600 and prevents the saline solution from contacting the conductive areas of the electrical connection 630. In this manner, the formation of electronic and ionic pathways in the electrical connection assembly 600 may be prevented, improving or even avoiding galvanic corrosion phenomena of the electrical connection assembly 600.

Accordingly, the electrical connection member 630, the first structural member 610 and the second structural member 620 can be prevented from being corroded, the contact between the first structural member 610 and the electrical connection member 630 and the contact between the second structural member 620 and the electrical connection member 630 are ensured to be stable, and the connection reliability of the electrical connection assembly 600 is improved. In addition, the structural strength of the first structural member 610 and the second structural member 620 can be ensured, and the influence on the reliability of the whole electronic device 10 can be avoided. In addition, the phenomenon of corrosion accumulation caused by galvanic corrosion can be avoided, the problems of extrusion and jacking of the first structural member 610 and the second structural member 620 caused by the phenomenon of corrosion accumulation can be avoided, and the dimensional stability of the first structural member 610 and the second structural member 620 can be ensured. Taking at least one of the first structural member 610 and the second structural member 620 as a circuit board as an example, if the corrosive substances squeeze and jack up the circuit board, board-level failure problems such as connection failure and device short circuit may be caused to the circuit board. The reliability of the circuit board can be ensured and the problem of board-level failure of the circuit board can be prevented by reducing or even eliminating the accumulation phenomenon of corrosions through improving galvanic corrosion.

With continued reference to fig. 4 and 5, in some embodiments, the conductive channel 6301 within the polymer elastomer 631 may be located in a central region of the polymer elastomer 631 in the planar direction of the polymer elastomer 631. In this way, in the circumferential direction of the polymer elastomer 631, the distance between the conductive channel 6301 and each part of the outer side wall of the polymer elastomer 631 is relatively large, the polymer elastomer 631 has a good protection effect on the conductive channel 6301, and the polymer elastomer 631 can isolate the salt solution from contacting the conductive filler 632 in the conductive channel 6301, so as to ensure the reliability of the electrical connection assembly 600. In addition, the electrical contact between the first structural member 610, the second structural member 620 and the electrical connector 630 is facilitated, the requirement on the docking precision of the electrical connection assembly 600 is low, the assembly of the electrical connection assembly 600 is facilitated, and the risk of electrical conduction failure of the electrical connection assembly 600 can be reduced.

Taking the example of the polymer elastomer 631 shaped like a cylinder, the center of the conductive path 6301 may coincide with the center of the polymer elastomer 631 on the surface of the polymer elastomer 631. Taking the example of the polymer elastomer 631 shaped like a rectangular cylinder, on the surface of the polymer elastomer 631, the center of the conductive path 6301 may coincide with the intersection of the diagonal lines of the polymer elastomer 631.

When at least one of the first and second structural members 610 and 620 is a metal member, a region of the metal member that is in electrical contact with the electrical connection member 630 may be provided as a laser etched region 601 (see fig. 4). That is, the metal piece has a laser etching area 601 on a surface facing the electrical connector 630, the laser etching area 601 corresponds to the conductive channel 6301 of the electrical connector 630, and the conductive channel 6301 of the electrical connector 630 can be in electrical contact with the laser etching area 601 on the metal piece. The oxide film on the surface of the metal piece can be removed by carrying out laser etching treatment on the surface of the metal piece. Taking a metal piece as an aluminum alloy as an example, an aluminum oxide film in a laser etching area 601 on the surface of the aluminum alloy can be removed. In this way, the conductive channel 6301 of the electrical connector 630 can make electrical contact with the metal part more stable and reliable, and ensure that the electrical connection assembly 600 conducts well.

Taking the first structural member 610 as a circuit board and the second structural member 620 as a metal member as examples, the manufacturing mode and the functional characteristics of the circuit board can ensure that the first structural member 610 and the electrical connection member 630 can be well conducted. At this time, only the region on the surface of the second structural member 620 that is in electrical contact with the electrical connector 630 may be set as the laser etched region 601. Taking the first structural member 610 and the second structural member 620 as metal members for example, the area on the surface of the first structural member 610 electrically contacted with the electrical connector 630 and the area on the surface of the second structural member 620 electrically contacted with the electrical connector 630 can be set as the laser etching area 601.

The area of the laser etching area 601 on the surface of the metal part facing the electrical connector 630 may be larger than the contact area between the conductive channel 6301 of the electrical connector 630 and the metal part, so that the electrical contact part of the electrical connector 630 and the metal part falls into the laser etching area 601 completely.

For example, only a local area on the surface of the metal part may be set as a laser etching area 601, so as to ensure that the electric contact part between the electric connector 630 and the metal part is located in the laser etching area 601. Taking the contact of the conductive channel 6301 of the electrical connector 630 with the central region of the metal part surface as an example, only the central region of the metal part surface may be set as the laser etched region 601.

Or the whole surface of the metal piece can be set as a laser etching area 601, and the laser etching area 601 occupies the whole surface of the metal piece. At this time, the butting precision of the electric connector 630 and the metal piece does not affect the contact area between the conductive channel 6301 of the electric connector 630 and the laser etching area 601 of the metal piece, so that the conductive channel 6301 of the electric connector 630 can be ensured to fall into the laser etching area 601 of the metal piece completely. By such arrangement, the requirement of the butt joint precision of the electric connector 630 and the metal piece can be reduced, and the assembly efficiency of the electric connector assembly 600 can be improved.

In this embodiment, the polymer elastomer 631 may be a rubber body, or the polymer elastomer 631 may be a rubber material. For example, the polymer elastomer 631 is made of silicone rubber. The rubber body has good elasticity, so that the polymer elastomer 631 can be tightly contacted with the first structural member 610 and the polymer elastomer 631 can be tightly contacted with the second structural member 620, and the electric conduction reliability of the electric connector 630 assembly can be ensured. And, the density of the rubber body is larger, and the rubber body has stronger waterproof performance, so that the polymer elastomer 631 can be ensured to isolate the salt solution outside the conductive spring connection area of the electric connection assembly 600.

As to how the addition of the conductive filler 632 into the polymer elastomer 631 is achieved, it may be that the conductive filler 632 is put into a mold during the compression molding of the polymer raw material so that the conductive filler 632 is dispersed in the polymer raw material. The conductive filler 632 is then aligned within the polymer feedstock by applying a magnetic field to localized areas of the polymer feedstock. Thus, at the colleague where the polymer feedstock is formed into the polymer elastomer 631, the conductive filler 632 forms a conductive channel 6301 within the polymer elastomer 631.

For example, magnetic members may be provided on both sides of the mold to apply a magnetic field to a partial region of the polymer raw material, and the direction of the magnetic field may be the height direction of the polymer elastomer 631. Under the action of the magnetic field, the conductive fillers 632 are aligned in the height direction of the polymer elastomer 631 to form the conductive channels 6301 extending in the height direction in the polymer elastomer 631. Also, the conductive filler 632 may occupy the entire height space of the polymer elastomer 631 such that the conductive channel 6301 formed by the conductive filler 632 extends to both side surfaces of the polymer elastomer 631.

Fig. 6 is a schematic structural diagram of a conductive filler in an electrical connector according to an embodiment of the present application. Referring to fig. 6, in order to enable the conductive filler 632 to be aligned in the polymer elastomer 631 and the conductive filler 632 to form the conductive channel 6301 in the polymer elastomer 631, the conductive filler 632 may include a magnetic core 6321 and a conductive plating 6322 in this embodiment. The magnetic core 6321 is an inner core of the conductive filler 632, the conductive coating 6322 is wrapped outside the magnetic core 6321, and the magnetic core 6321 and the conductive coating 6322 together form the conductive filler 632.

The magnetic core 6321 of the conductive filler 632 may be a metallic material that is attracted to a magnetic member. By disposing the magnetic members at the respective positions of the polymer elastic body 631, a magnetic field is applied to a partial region of the polymer elastic body 631, and the magnetic core 6321 of the conductive filler 632 orients the conductive filler 632 in the height direction of the polymer elastic body 631 under the effect of the magnetic field force. Thus, the conductive filler 632 may be intensively dispersed in a partial region of the polymer elastomer 631, forming a conductive path 6301 extending to both side surfaces in the height direction of the polymer elastomer 631.

By way of example, the magnetic core 6321 of the conductive filler 632 may comprise a ferromagnetic metal material such as iron, nickel, cobalt, or the like.

The ferromagnetic metal material comprising the magnetic core 6321 is generally relatively weak in electrical conductivity. The conductive coating 6322 may be made of a metal material having a high conductivity by wrapping the conductive coating 6322 around the magnetic core 6321. The conductive fillers 632 are arranged in a directional manner to be contacted with each other through the conductive coating 6322, and the conductive coating 6322 can achieve good electrical conduction between the conductive fillers 632, so as to ensure the conductive performance of the conductive channels 6301 formed by the conductive fillers 632. Thus, the conductive path 6301 of the electrical connector 630 is ensured, and reliable electrical connection of the first structural member 610 and the second structural member 620 can be achieved.

Illustratively, the conductive coating 6322 of the conductive filler 632 may include a metallic material having excellent conductive properties such as silver, gold, tin, and the like.

With continued reference to fig. 4 and 5, in some embodiments, the electrical connector 630 may further include a glue layer 633, and at least one side surface of the polymer elastomer 631 in the height direction may be provided with the glue layer 633, and the electrical connector 630 is adhered to at least one of the first structural member 610 and the second structural member 620 by the glue layer 633, so as to achieve a fixed connection between the electrical connector 630 and the structural member.

When the first structural member 610 and the second structural member 620 have metal members therein, the electrical connector 630 may be bonded to the metal members by an adhesive layer 633 to fixedly connect the electrical connector 630 to the metal members. In this way, the electrical connector 630 and the metal piece can be firmly connected, and the conductive channel 6301 of the electrical connector 630 and the metal piece can be reliably and well electrically contacted. Thus, the stability, reliability and electrical conductivity of the electrical connection assembly 600 are ensured.

The adhesive layer 633 may avoid the area of the conductive channel 6301 on the surface of the polymer elastomer 631, for example, the adhesive layer 633 may be disposed around the outer circumference of the conductive channel 6301, so as to ensure that the conductive channel 6301 may directly electrically contact with the metal member. Moreover, when the metal piece is provided with the laser etching area 601 towards one side surface of the polymer elastomer 631, the laser etching area 601 may occupy only a local area of the metal piece surface, the conductive channel 6301 of the polymer elastomer 631 is in electrical contact with the laser etching area 601 of the metal piece, and the adhesive layer 633 may be enclosed on the periphery of the laser etching area 601.

And when the first structural member 610 and the second structural member 620 have circuit boards therein, the electrical connector 630 may directly abut against the circuit boards through the polymer elastomer 631. That is, the adhesive layer 633 may not be provided between the polymer elastomer 631 and the circuit board. On the one hand, the material characteristics of the circuit board and the elasticity of the polymer elastomer 631 can ensure that the polymer elastomer 631 is tightly and reliably attached to the circuit board. On the other hand, the adhesive layer 633 can also be prevented from affecting the stability of the surface material of the circuit board, and interference of the adhesive layer 633 to devices arranged on the circuit board is avoided.

Taking the first structural member 610 as a circuit board and the second structural member 620 as a metal member as an example, the surface of the polymer elastomer 631 facing the first structural member 610 may not be provided with the adhesive layer 633, and the polymer elastomer 631 is directly in close contact with the circuit board. A glue layer 633 may be disposed on a side surface of the polymer elastomer 631 facing the second structural element 620, the polymer elastomer 631 is adhered to the second structural element 620 by the glue layer 633, and the glue layer 633 is avoided from the conductive channel 6301 in the polymer elastomer 631, so that the conductive channel 6301 of the polymer elastomer 631 can electrically contact the second structural element 620 (see fig. 4 and 5).

Illustratively, the adhesive layer 633 disposed on the surface of the polymer elastomer 631 may be a waterproof adhesive layer. The waterproof glue layer has the functions of adhering and fixing the electric connector 630 and the first structural member 610 (or the second structural member 620), and also has waterproof and sealing effects, and the waterproof glue layer can also perform waterproof protection on the conductive channel 6301 enclosed therebetween so as to isolate the salt solution outside the conductive channel 6301 and prevent the electric connector assembly 600 from generating galvanic corrosion phenomenon, so that the structural strength and the electric connection reliability of the electric connector assembly 600 are not affected.

Fig. 7 is a view of an electrical connector according to an embodiment of the present application. Fig. 8 is a block diagram illustrating another view of an electrical connector according to an embodiment of the present application. Fig. 9 is a side view of a polymer elastomer provided in an embodiment of the present application.

Referring to any one of fig. 7 to 9, in the present embodiment, at least one side surface in the height direction of the polymer elastomer 631 may be provided with a boss portion 6311. By providing the raised boss portion 6311 on the surface of the polymer elastomer 631, the polymer elastomer 631 is brought into contact with the first structural member 610 (or the second structural member 620) of the corresponding side through the boss portion 6311. Wherein the conductive channels 6301 within the polymer elastomer 631 may be located within the region of the boss portion 6311 to make electrical contact with the first structural element 610 (or the second structural element 620) while making surface contact with the polymer elastomer 631.

The polymer elastomer 631 is electrically contacted with the first structural member 610 (or the second structural member 620) by providing the boss portion 6311, the boss portion 6311 is protruded on the surface of the polymer elastomer 631, and the volume occupied by the boss portion 6311 is small. In this way, under the contact pressure between the boss portion 6311 and the first structural member 610 (or the second structural member 620), the boss portion 6311 may generate good elastic deformation, so that the boss portion 6311 is closely contacted with the first structural member 610 (or the second structural member 620) on the corresponding side, and reliable electrical conduction between the conductive channel 6301 in the polymer elastomer 631 and the first structural member 610 (or the second structural member 620) is ensured. In addition, in the compression molding process of the polymer elastomer 631, the shape of the mold is matched with that of the polymer elastomer 631, and the mold can be provided with a convex structure corresponding to the boss part 6311, so that the position of the conductive channel 6301 can be conveniently positioned, and the application position of the magnetic field can be accurately positioned.

When the conductive path 6301 is located at the central region in the plane direction of the polymer elastomer 631, a boss portion 6311 may be provided at the central region of the surface of the polymer elastomer 631 in cooperation therewith, so that the conductive path 6301 located in the region where the boss portion 6311 is located may be located at the central region of the polymer elastomer 631.

As an embodiment, as shown in fig. 7 and 8, both side surfaces in the height direction of the polymer elastomer 631 may be provided with the boss portion 6311, and the polymer elastomer 631 is electrically contacted with the first structural member 610 through the boss portion 6311, and the polymer elastomer 631 is also electrically contacted with the second structural member 620 through the boss portion 6311. At this time, the boss portions 6311 located on both side surfaces of the polymer elastomer 631 may be coaxially disposed, and the contact pressure between the polymer elastomer 631 and the first structural member 610 and the contact pressure between the polymer elastomer 631 and the second structural member 620 may be located on the same line to improve the stress stability of the electrical connection assembly 600. For example, the boss portions 6311 of the two side surfaces of the polymer elastomer 631 may be located on the center line of the polymer elastomer 631 to achieve the overall force balance of the electrical connection assembly 600.

Here, as shown in fig. 5 and 7, taking direct contact between the polymer elastomer 631 and the first structural member 610 as an example, for example, the first structural member 610 is a circuit board, the polymer elastomer 631 is electrically contacted to the first structural member 610 toward the boss portion 6311 on the one side surface of the first structural member 610. At this time, a positioning groove 602 may be disposed on a side surface of the first structural member 610 facing the polymer elastomer 631 (see fig. 5), where the positioning groove 602 is located in a central area of the surface of the first structural member 610, and the boss portion 6311 of the polymer elastomer 631 may be locked into the positioning groove 602, so as to avoid risks of shifting, shaking, etc. between the polymer elastomer 631 and the first structural member 610, and ensure stable and reliable connection between the first structural member 610 and the polymer elastomer 631.

As shown in fig. 5 and 8, for example, the second structural member 620 is a metal member, and the polymer elastomer 631 and the second structural member 620 are bonded by an adhesive layer 633, where the boss portion 6311 on one side surface of the polymer elastomer 631 facing the second structural member 620 is in electrical contact with the second structural member 620, the adhesive layer 633 is disposed around the periphery of the boss portion 6311, and the adhesive layer 633 is bonded to the second structural member 620.

As another embodiment, the boss portion 6311 may be provided only on one side surface in the height direction of the polymer elastic body 631. At this time, the boss portion 6311 may be provided at one side surface covered with the adhesive layer 633. Continuing to take the first structural member 610 as a circuit board and the second structural member 620 as a metal member as an example, the adhesive layer 633 covers a surface of the polymer elastomer 631 facing the second structural member 620, and the boss 6311 may be disposed on a surface of the polymer elastomer 631 facing the second structural member 620. In this way, the interference of the adhesive layer 633 to the boss portion 6311 can be avoided, and the boss portion 6311 can occupy the height space of the adhesive layer 633, so that the boss portion 6311 can be abutted against the surface of the second structural member 620 while the adhesive layer 633 is adhered to the second structural member 620.

In addition, as shown in conjunction with fig. 7 and 9, in some embodiments, at least one side surface of the polymer elastomer 631 in the height direction has an inclined portion 6312, and the inclined portion 6312 may extend from an edge of the polymer elastomer 631 toward a center of the polymer elastomer 631. Wherein the height of the polymer elastomer 631 gradually increases from the outer edge of the inclined portion 6312 (the inclined portion 6312 is located at one side edge of the outer side wall of the polymer elastomer 631) to the inner edge of the inclined portion 6312 (the inclined portion 6312 is located at one side edge near the center of the polymer elastomer 631).

By providing the inclined portion 6312 on the surface of the polymer elastic body 631, a slope is formed in the edge region of the polymer elastic body 631. In this way, the thickness of the edge region of the corresponding side of the polymer elastomer 631 may be reduced, facilitating the elastic deformation of the polymer elastomer 631, making the polymer elastomer 631 more closely contact the first structural element 610 (or the second structural element 620) of the corresponding side, and ensuring that the conductive channel 6301 in the polymer elastomer 631 is reliably in electrical contact with the first structural element 610 (or the second structural element 620). In addition, since the inclined portion 6312 is a straight inclined surface, the phenomenon of stress concentration of the polymer elastomer 631 in the area where the inclined portion 6312 is located can be avoided, so that stability and reliability of the polymer elastomer 631 can be improved.

When the side of the polymer elastic body 631 is provided with the boss portion 6311, a flat portion may be provided between the inclined portion 6312 and the boss portion 6311 as a transition. When the boss portion 6311 on the side of the polymer elastic body 631 is caught in the positioning groove 602 formed on the first structural member 610 (or the second structural member 620), the flat portion between the inclined portion 6312 and the boss portion 6311 may abut on the surface of the first structural member 610 (or the second structural member 620) (see fig. 5). In this way, the first structural member 610 (or the second structural member 620) presses the planar portion of the polymer elastomer 631, the polymer elastomer 631 is elastically deformed by the inclined portion 6312, so that the planar portion of the polymer elastomer 631 is closely contacted with the first structural member 610 (or the second structural member 620), and the force is transmitted to the boss portion 6311 of the polymer elastomer 631, so that the boss portion 6311 is more closely contacted with the first structural member 610 (or the second structural member 620). When the side of the polymer elastomer 631 is provided with the adhesive layer 633, the planar portion of the polymer elastomer 631 may serve as a receiving surface of the adhesive layer 633.

As an example, as shown in connection with fig. 5 and 9, the polymer elastomer 631 may be in direct contact with the first structural element 610, e.g., the first structural element 610 is a circuit board. At this time, a surface of the polymer elastomer 631 facing the first structural member 610 may be provided with an inclined portion 6312 to increase elastic deformation performance of the side of the polymer elastomer 631. The boss portion 6311 of the polymer elastomer 631 facing the surface of the first structural element 610 may be snapped into the positioning groove 602 of the first structural element 610, with the planar portion of the polymer elastomer 631 facing the surface of the first structural element 610. The polymer elastomer 631 and the second structural element 620 are bonded by a glue layer 633, for example the second structural element 620 is a metal element. At this time, the inclined portion 6312 may not be disposed on the side surface of the polymer elastomer 631 facing the second structural element 620, and the side surface of the polymer elastomer 631 may be a planar portion at the outer periphery of the boss portion 6311, and the adhesive layer 633 may be attached to the planar portion at the outer periphery of the boss portion 6311, so as to ensure that the adhesive layer 633 has a sufficient coverage area.

The embodiment of the application also provides a manufacturing method of the electrical connector 630, which is used for manufacturing the electrical connector 630. The production method will be described in detail below.

Fig. 10 is a flowchart illustrating steps of a method for manufacturing an electrical connector according to an embodiment of the present application. Referring to fig. 10, the method for manufacturing an electrical connection according to the present embodiment includes the following steps:

and S100, placing the polymer raw material into a mould for moulding to form the polymer elastomer 631.

First, a polymer raw material is put into a mold and heated. The polymer feedstock is formed into a polymer elastomer 631 of a desired shape and size by compression molding the polymer feedstock.

Taking the polymer elastomer 631 as the rubber body, the polymer raw materials may include raw rubber, which is a base material of the rubber body, and various compounding agents, which are auxiliary materials added to improve certain properties of the rubber body. In addition, the polymer raw material can also comprise fiber materials such as cotton, hemp, wool, artificial fiber, synthetic fiber and the like, and the fiber materials can be used as a framework material of the rubber body so as to strengthen the mechanical strength of the rubber body and avoid plastic deformation of the rubber body.

S200, in the compression molding process, the conductive filler 632 is put into the polymer raw material, and a magnetic field is applied to a local area of the polymer raw material, so that the conductive filler 632 is aligned to form a conductive channel 6301 in the polymer elastomer 631, wherein the conductive channel 6301 extends to two side surfaces of the polymer elastomer 631 along the height direction of the polymer elastomer 631.

S200 does not refer to a process performed after S100, but may refer to a process performed simultaneously during S100.

Specifically, the conductive filler 632 is put into the polymer raw material during compression molding of the polymer raw material in the mold. Wherein, as previously described, the conductive filler 632 can be oriented under the influence of a magnetic field. For example, the conductive filler 632 includes a magnetic core 6321 and a conductive plating 6322 wrapped around the outside of the magnetic core 6321.

After the conductive filler 632 is put into the polymer raw material, a magnetic field is applied to a partial region of the polymer raw material, so that the conductive filler 632 is aligned under the effect of the magnetic field, and the conductive fillers 632 are closely contacted with each other to form the conductive channel 6301 in the molded polymer elastomer 631. The magnetic field direction is, for example, a height direction of the polymer elastomer 631, so that the conductive filler 632 is aligned in the height direction of the polymer elastomer 631, and the conductive filler 632 occupies the entire space in the height direction of the polymer elastomer 631. Thus, the conductive channels 6301 formed in the polymer elastomer 631 may extend in the height direction of the polymer elastomer 631, and the conductive channels 6301 extend to both side surfaces of the polymer elastomer 631.

For example, magnetic members may be disposed on both sides of the mold, and the positions of the magnetic members may correspond to the target positions of the conductive paths 6301, and the magnetic members on both sides may be disposed along the height direction of the mold, for example. A magnetic field is generated between the magnetic members on both sides, and the direction of the magnetic field is the height direction of the polymer elastomer 631 to be molded, so that the conductive filler 632 is aligned along the height direction of the polymer elastomer 631.

If at least one side surface of the polymer elastomer 631 in the height direction has the boss portion 6311, the polymer elastomer 631 is in electrical contact with the first structural member 610 (or the second structural member 620) on the corresponding side through the boss portion 6311. At this time, the conductive path 6301, which is required to be formed in the polymer elastomer 631, may be located in the region where the boss portion 6311 is located, so that the conductive path 6301 located in the region where the boss portion 6311 is located may enable the electrical connection 630 to be electrically conducted with the first structural member 610 (or the second structural member 620) while the boss portion 6311 is in contact with the first structural member 610 (or the second structural member 620).

In this regard, a magnetic field may be applied in the region of the boss portion 6311 of the polymer elastomer 631 to be molded such that the conductive filler 632 is aligned in the region of the boss portion 6311 to form the conductive path 6301 in the region of the boss portion 6311. For example, a magnetic member may be provided on the mold at a position corresponding to the boss portion 6311 of the polymer elastic body 631 to be molded such that a magnetic field generated by the magnetic member is located in a region where the boss portion 6311 of the polymer elastic body 631 is located.

If at least one side surface of the polymer elastomer 631 in the height direction is provided with a glue layer 633 (see fig. 8), the electrical connector 630 is adhered to the first structural member 610 (or the second structural member 620) on the corresponding side through the glue layer 633. At this time, after the polymer elastomer 631 is molded and the conductive path 6301 is formed in the polymer elastomer 631, it is further included to form a glue layer 633 on the surface of the polymer elastomer 631.

Wherein, a separate adhesive layer 633 may be previously manufactured, and the adhesive layer 633 is attached to the surface of the polymer elastomer 631. Or the adhesive layer 633 is formed on the surface of the polymer elastomer 631 through a dispensing process. The embodiment of the present application is not particularly limited thereto. For example, the adhesive layer 633 may be made of a waterproof material, or the adhesive layer 633 may be a waterproof adhesive layer.
