Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector and an electronic device. Background Art

[0002] The basic structure of Pogopin includes a spring-loaded needle, needle tube and base. The working principle relies on the elastic contact between the probe and the corresponding contact to achieve current conduction. Due to the necessity of the needle to move up and down, there needs to be a certain gap between the needle and the needle tube to ensure that the needle can move freely in the needle tube. However, due to the existence of the gap, it is impossible to prevent foreign matter and liquid from entering the needle tube. Once foreign matter, dirt and liquid enter the needle tube, it will cause large internal friction, and the needle will get stuck in the needle tube, resulting in poor charging contact. The increase in resistance may also cause a short circuit, internal corrosion of the needle tube, and the needle cannot rebound. In severe cases, it will cause the entire system to fail, affecting the reliability of the product and user experience. It is generally protected by a simple sealing ring or dust cover. Although it can alleviate the problem to a certain extent, the protection effect is limited under long-term use. Utility Model Content

[0038] The utility model provides a connector and an electronic device.

[0039] See also Figure 1 and Figure 2 In one embodiment of the present utility model, the connector comprises:

[0041] pogopin 200, disposed in the accommodating cavity and electrically connected to the PCB board 400; and

[0042] The connecting component 300 is disposed on one side of the housing 100 having the through hole 130 and seals the through hole 130 . The two sides of the connecting component 300 are respectively used to connect the pogo pin 200 and the product to be charged 500 .

[0043] In the technical solution of the utility model, the connector includes a housing 100, a pogopin 200 and a connecting assembly 300. A receiving cavity is formed inside the housing 100, and a PCB board 400 is placed in the receiving cavity. The pogopin 200 is in the receiving cavity, and one end is electrically connected to the PCB board 400, and the other end is connected to the product to be charged 500 through the connecting assembly 300, so that the current between the product to be charged 500 and the PCB board 400 is conducted. A through hole 130 is provided on one side of the housing 100, and the connecting assembly 300 is provided in the through hole 1 On one side of 30, one end of the connecting component 300 passes through the through hole 130 and contacts the pogo pin 200 inside the accommodating cavity, and the other end is used to connect with the contact 510 of the product to be charged 500 outside the accommodating cavity to achieve conduction, and the outer periphery of the connecting component 300 blocks the through hole 130 to seal the through hole 130. After the through hole 130 is sealed, foreign matter and the like cannot enter the through hole 130, let alone the gap between the needle tube and the needle. That is, the connecting component 300 can achieve current conduction while sealing the through hole 130, thereby improving the protection effect.

[0044] Specifically, the connector can be used for products 500 such as headphones and bracelets. The shell 100 is the appearance of the charging stand. The shell 100 can be square, round or other shapes selected according to aesthetics. There is no restriction on the shape of the shell 100. The shell 100 has a accommodating cavity inside. In addition to the PCB board 400, other structures are installed inside the accommodating cavity, which are not related to the present technical solution and are not explained here. The pogopin 200 is in the accommodating cavity, and one end of the needle is facing the through hole 130, which is convenient for connection with the connecting component 300. In addition, multiple pogopins 200 can be arranged on the PCB board 400, and the number of through holes 130 and the connecting component 300 is consistent with that of pogopins 200, and they are arranged one by one.

[0045] In an embodiment of the present utility model, the connection assembly 300 includes:

[0046] The sealing member 310 is disposed in the through hole 130 , and the sealing member 310 is provided with a through hole 311 ;

[0047] The conductive member 320 is disposed in the through hole 311, and both ends of the conductive member 320 protrude from the sealing member 310 respectively, and the outer periphery of the conductive member 320 is in contact with the inner wall of the through hole 311;

[0048] And / or, a plating layer is provided on the outer periphery of the conductive member 320 .

[0049] Please refer to Figure 2 and Figure 3The connection assembly 300 includes a sealing member 310 and a conductive member 320. The sealing member 310 is fixedly connected to the conductive member 320, and the two ends of the conductive member 320 protrude from the two side surfaces of the sealing member 310. The sealing member 310 is located outside the housing 100. The through hole 311 on the sealing member 310 is connected to the through hole 130. One end of the conductive member 320 passes through the through hole 311 and the through hole 130 to enter the accommodating cavity and connect with the pogopin 200, and the other end is outside the accommodating cavity. When charging is required, the contact 510 of the product 500 contacts the conductive member 320, and connects with the pogopin 200 through the conductive member 320. pogopin200 is turned on, the seal 310 is at the through hole 130, the inner wall of the through hole 311 is closely fitted with the outer wall of the conductive member 320, and the seal 310 and the conductive member 320 cooperate to seal the through hole 130, which can prevent foreign matter from entering the accommodating cavity; in addition, since the seal 310 is arranged at the through hole 130 and does not contact with pogopin200, when the product 500 to be charged contacts the conductive member 320 for charging, it does not affect the movement of the needle in the needle tube of pogopin200. Compared with directly adding a waterproof ring at the needle, it not only has a better protection effect, but also reduces friction.

[0050] In another embodiment, by providing a coating on the periphery of the conductive part 320, corrosive media such as sweat and moisture can be effectively isolated, the service life can be extended, and the surface hardness can be improved to reduce wear. The coating can be a composite coating, generally including nickel plating and gold plating, with the nickel plating layer as the bottom layer and the gold plating layer as the top layer.

[0051] In the embodiment of the present invention, an end of the conductive member 320 close to the pogopin 200 is provided with an inwardly concave arc surface.

[0052] Please refer to Figure 2 and Figure 5 A circular arc surface is provided at the end of the conductive member 320, so that when the conductive member 320 contacts the pogopin 200, the needle head of the pogopin 200 is within the circular arc surface, and the contact with the conductive member 320 is more stable, and the circular arc surface can automatically correct the needle head, so that the conductive member 320 and the pogopin 200 are aligned up and down.

[0053] In the embodiment of the present invention, the sealing member 310 and the conductive member 320 are integrally formed.

[0054] Specifically, the sealing member 310 and the conductive member 320 are integrally formed, and can be specifically injection molded in a mold, so as to improve the stability of the connection between the sealing member 310 and the conductive member 320 and improve the sealing effect.

[0055] In the embodiment of the present invention, the housing 100 includes a shell 110 and a cover 120 . The shell 110 and the cover 120 together form a receiving cavity, and the through hole 130 is located in the cover 120 .

[0056] Please refer to Figure 1 One side of the shell 110 is open, so that the accommodating cavity is open, the cover body 120 is arranged on the open side and connected to the shell 110, the through hole 130 is arranged on the cover body 120, and the connecting component 300 is arranged on the cover body 120, so that the accommodating cavity is connected to the outside only through the through hole 311. The protection effect is improved by the connecting component 300, and after long-term use, the cover body 120 and the shell 110 can also be disassembled for repair, which is convenient to use.

[0057] In an embodiment of the present invention, the through hole 130 includes a first hole position 131 close to the accommodating cavity and a second hole position 132 away from the accommodating cavity. The first hole position 131 is smaller than the second hole position 132. The sealing member 310 is located at the second hole position 132, and the bottom wall of the sealing member 310 is in contact with the top of the first hole position 131.

[0058] Please refer to Figure 4 and Figure 5 The through hole 130 is stepped, that is, the size of the first hole position 131 close to the inside of the accommodating cavity is smaller than the size of the second hole position 132 far away from the accommodating cavity. In the present embodiment, the first hole position 131 and the second hole position 132 are both circular, and the first hole position 131 and the second hole position 132 are coaxially arranged. The bottom wall of the seal 310 is in close contact with the upper end of the first hole position 131 to seal the first hole position 131, that is, the seal 310 is limited at the second hole position 132, which is convenient for installing the seal 310. The outer periphery of the seal 310 can fit with the inner wall of the second hole position 132 so that the conductive member 320 on the seal 310 is coaxial with the second hole position 132, so as to better connect with the pogopin 200. There is no restriction on this.

[0059] In the embodiment of the present invention, a side of the sealing member 310 away from the accommodating cavity does not protrude from the second hole 132 .

[0060] Please refer to Figure 2 The upper end of the sealing member 310 may be lower than the second hole 132 , or may be flush with the cover 120 , thereby improving the aesthetics of the housing 100 .

[0061] In the embodiment of the present utility model, the material of the seal 310 is plastic. Plastic provides a stable packaging structure for the conductive member 320 to avoid physical deformation of the conductive member 320. The seal 310 preferably adopts soft plastic, which can not only effectively prevent foreign matter such as dust, moisture and grease from entering the second hole 132 and then entering the accommodating cavity to affect the use of the pogopin 200, but also effectively protect the interior of the accommodating cavity from corrosion and extend the service life. The plastic material structure is light and easy to process and carry; and because the plastic material is soft, when the contact 510 of the product 500 contacts the conductive member 320, a certain collision will occur, which can ensure that the conductive member 320 moves up and down during the collision to avoid damage.

[0062] In the embodiment of the present invention, the conductive member 320 is made of metal. Specifically, the conductive member 320 can be made of copper alloy or stainless steel, which has good conductivity, but the material of the conductive member 320 is not limited to these two and can also be made of other metal materials as long as the current can be conducted.

[0063] The utility model also proposes an electronic device, including a connector. The specific structure of the connector refers to the above embodiments. Since the electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0064] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
