Referring to fig. 1, fig. 1 is a schematic view of an electronic device 100 according to an embodiment of the disclosure. Referring to fig. 2 and 3, the electronic device 100 includes a housing 3 and a connector 10. The housing 3 has an insertion hole 31. The connector 10 is housed inside the electronic apparatus 100. The connector 10 includes a sealing member 1 and an electrical connector 2. One end of the electrical connector 2 is disposed in the jack 31 for electrically connecting an external device to the electronic device 100. The electric connector 2 may be a USB (Universal Serial Bus) socket, an earphone socket, a TF (Trans Flash) card socket, an SD (Secure Digital) card socket, or the like. The electronic device 100 may be any device provided with an electrical connection 2, such as: intelligent devices such as telephones, televisions, tablet computers, mobile phones, cameras, personal computers, notebook computers, vehicle-mounted devices, wearable devices, and the like. In the present embodiment, the electrical connector 2 is referred to as a USB socket for example.

Referring to fig. 3, the sealing member 1 includes a first end surface 11 and a second end surface 12 disposed opposite to each other, and a through hole 13 penetrating the first end surface 11 and the second end surface 12. Referring to fig. 3 and fig. 4, the through hole 13 is used for accommodating the electrical connector 2, that is, the sealing element 1 is sleeved on the electrical connector 2. The inner side wall 13a of the through hole 13 is provided with a first protrusion 14. The first protrusion 14 may be an annular protrusion, and the first protrusion 14 is disposed around the inner sidewall 13a of the through hole 13. The first bump 14 is hermetically connected with the electrical connector 2,

so that the portion of the sealing member 1 excluding the first projection 14 is used to form a clearance M with the outer peripheral wall 2a of the electric connector 2. When the connector 10 is applied in an electronic device 100, water stains enter the sealing member 1 from the first end face 11. The first projections 14 are close to the second end face 12 so that the length of the gap M in the central axis direction of the through hole 13 is long. When less water stain enters the sealing member 1, the water stain will stay in the gap M, and will not flow to the first protrusion 14, and will not invade the electronic component on one side of the connector 10.

Through being equipped with first arch 14 at inside wall 13a of sealing member 1, when electric connector 22 was located in the through-hole 13 of sealing member 1, first arch 14 was sealed between sealing member 1 and the periphery wall 2a of electric connector 22, first arch 14 makes the clearance M is formed between inside wall 13a of through-hole 13 and the periphery wall 2a of electric connector 22, and when water stain invaded other electronic component in electronic equipment 100 through sealing member 1 and electric connector 22, first arch 14 was stained with water stain separation in clearance M to avoid other electronic component in electronic equipment 100 to receive water stain invasion, and this electronic equipment 100 has fine waterproof, dust proof performance, has improved electronic equipment 100's reliability.

In one embodiment, referring to fig. 4, the first protrusion 14 includes a fixing section 141 and an extending section 142. The fixing section 141 is fixed to the inner sidewall 13a of the through hole 13. The fixing section 141 extends toward the central axis of the through hole 13 in the radial direction of the through hole 13. The extending direction of the extending section 142 intersects the extending direction of the fixing section 141. That is, the extension portion 142 may be inclined from the fixing portion 141 toward the first end surface 11 or the second end surface 12.

Further, referring to fig. 4, the extension 142 has a first end 143 and a second end 144 opposite to each other. The first end 143 is connected to the fixed section 141, and the second end 144 is an end away from the fixed section 141. The second end 144 is adjacent the first end face 11 relative to the first end 143. I.e. the extension 142 is inclined from the fixing section 141 towards the first end surface 11.

In the present embodiment, the electrical connector 2 protrudes from the second end face 12 of the sealing member 1 into the through hole 13 of the sealing member 1, and the inclined direction of the extension section 142 matches the protruding direction of the electrical connector 2. In the process of mounting the electric connector 2 to the sealing member 1, the electric connector 2 reaches the first end 143, and the first end 143 abuts against the outer peripheral wall 2a of the electric connector 2 to generate a pressing force to the outer peripheral wall 2a of the electric connector 2. Since the size of the through hole 13 formed by the second end 144 is smaller than the size of the through hole 13 formed by the first end 143, after the electric connector 2 enters the second end 144 of the extension section 142, the pressing force of the second end 144 of the extension section 142 on the outer circumferential wall 2a of the electric connector 2 is larger than the pressing force of the first end 143 of the extension section 142 on the outer circumferential wall 2a of the electric connector 2, so that the sealing member 1 and the electric connector 2 are more and more tightly interacted. When water is trapped between the sealing member 1 and the electrical connector 2, the second end 144 of the extension 142 provides a good barrier to water entering the space, and prevents water from entering other electronic components in the electronic device 100 through the sealing member 1.

Further, referring to fig. 5, at least one notch 145 is disposed on the second end 144. Specifically, the second end 144 may be provided with a plurality of notches 145, and the notches 145 extend toward the first end 143. When the electrical connector 2 is squeezed into the second end 144, the gap 145 of the second end 144 is increased in size under the force of the electrical connector 2 applied to the second end 144, and the gap 145 of the second end 144 can relieve the force of the electrical connector 2 applied to the sealing member 1, so as to prevent the second end 144 of the extension section 142 from cracking. The electrical connector 2 may be used for an external plug to electrically connect to the electronic device 100. Heat is generated in the electrical connector 2, which may cause the sealing member 1 to expand, and the gap 145 of the second end 144 may relieve the sealing member 1 from the expansion force caused by heat, thereby preventing the sealing member 1 from cracking and improving the life of the sealing member 1.

In one embodiment, referring to fig. 3, the first protrusion 14 is provided with an abutting portion 14 a. The abutting portion 14a abuts against the outer peripheral wall 2a of the electrical connector 2. The abutting portion 14a may be a circular arc surface or a flat surface. That is, the cross section of the first protrusion 14 may be a semicircle, a regular trapezoid or an inverted trapezoid. The abutting portion 14a is an arc surface or a plane, so that the attaching area between the sealing element 1 and the electric connecting element 2 can be increased, and the sealing performance between the sealing element 1 and the electric connecting element 2 can be increased.

Further, the foam layer 7 may contain a detection substance therein. The color of the detection substance may change upon contact with water. The foam layer 7 contains a detection substance, so that the sealing element 1 has a function of detecting whether water enters the sealing element 1. The material of the detection substance can be potassium permanganate or anhydrous copper sulfate and the like. The foam layer 7 can be white or light-colored, so that the color change of the detection substance after meeting water can be recognized by naked eyes.

Further, a foam layer 7 containing a detection substance may be disposed between the first protrusion 14 and the second end face 12 for detecting whether water passes through the first protrusion 14 and enters the electronic device 100.

By fixing to the housing 3 with the screw fixing member 5, the electric connector 2 can be fixed to the housing 3 to restrict the movement of the electric connector 2 in the housing 3. In other embodiments, the fixing member 5 may also be connected to the housing 3 by gluing, welding or other fixing means.

Further, the second end face 12 is made of an elastically deformable material. When the fixing member 5 is made of hard materials such as metal materials, the second end face 12 is made of an elastically deformable material, and the rigid force of the fixing member 5 on the second end face 12 can be buffered, so that the fixing member 5 can not damage the second end face 12 when extruding the second end face 12.

In an embodiment, referring to fig. 16, the cross section of the second groove 32 is circular arc. The section of the second protrusion 15 is also arc-shaped, the second protrusion 15 can deform under the extrusion of the fixing piece 5, and the section of the second groove 32 is arc-shaped, so that the deformed second protrusion 15 can still be attached to the inner wall of the second groove 32, and the sealing performance of the sealing element 1 is improved.

In one embodiment, referring to fig. 16, the inner sidewall of the insertion hole 31 has an abutting surface 37. The abutment surface 37 intersects with the extending direction of the insertion hole 31. Specifically, the abutment surface 37 may be perpendicular to the extending direction of the insertion hole 31. The abutment surface 37 may extend in the circumferential direction of the insertion hole 31 on the inner sidewall of the insertion hole 31. The abutment surface 37 abuts the start 21 of the electrical connector 2 to limit the maximum distance the electrical connector 2 enters into the receptacle 31.

Further, referring to fig. 16, the housing 3 is provided with a stopper 38. The stopper 38 is disposed in the receiving cavity 33. The stopper 38 is opposite to the insertion hole 31. The stop member 38 abuts against the tail end 22 of the electrical connector 2 to limit the electrical connector 2.

In the assembling process of the electronic device provided by the embodiment of the application, the sealing element 1 is sleeved on the middle section 25 of the electric connecting element 2, so that the first protrusion 14 is sealed on the outer peripheral wall 2a of the electric connecting element 2, and when the first groove 24 is formed in the outer peripheral wall 2a of the electric connecting element 2, the first protrusion 14 is filled in the first groove 24, so that the sealing element 1 is in sealed connection with the electric connecting element 2. The fixing piece 5 is sleeved on the tail end 22 of the electric connector 2, and the fixing piece 5 is abutted to the second end face 12 of the electric connector 2. The leading end 21 of the electrical connector 2 is inserted into the insertion hole 31 of the housing 3, and the leading end 21 of the electrical connector 2 is abutted to the abutment surface 37. At this time, the first end surface 11 of the electrical connector 2 is attached to the surface 36 to be sealed of the housing 3, and the second protrusion 15 on the first end surface 11 is aligned with the second groove 32 to be sealed between the housing 3 and the sealing member 1. The fixing member 5 is fixed to the second plate 35 of the housing 3, at this time, the distance between the fixing member 5 and the first plate 34 is just equal to or slightly less than the length of the sealing member 1, that is, the fixing member 5 generates a pressing force on the sealing member 1 toward the starting end 21 of the electrical connector 2 in the process of being fixed to the housing 3, the pressing force causes the second protrusion 15 to be filled in the second groove 32, and the first end face 11 is sealingly attached to the surface to be sealed 36 of the first plate 34 to seal the opening of the insertion hole 31.

When water stain enters from the insertion hole 31, since the tail end 22 of the electrical connector 2 is closed, the water stain can only invade into the electronic device 100 from the gap between the inner side wall of the insertion hole 31 and the outer peripheral wall 2a of the electrical connector 2, thereby affecting the circuit, the electronic components and the like in the electronic device 100. Because the first end surface 11 of the sealing member 1 is sealed in the opening area of the insertion hole 31 on the surface 36 to be sealed, water stains can only invade along the inner side wall of the sealing member 1 and the outer peripheral wall 2a of the electric connector 2, and because the first protrusion 14 of the sealing member 1 is sealed in the outer peripheral wall 2a of the electric connector 2, the water stains can not pass through, namely, the sealing member 1 realizes waterproof sealing on the insertion hole 31.
