Description

Technical Field

[0001] The utility model relates to the technology of the field of connector accessories, in particular to a waterproof contact PIN needle structure for wearable devices. Background Art

[0002] Wearable devices mostly exist in the form of portable accessories with partial computing functions and can be connected to mobile phones and various terminals. The mainstream product forms include watches supported by the wrist (including watches and wristbands, etc.), shoes supported by the feet (including shoes, socks or other leg-worn products in the future), Glass supported by the head (including glasses, helmets, headbands, etc.), as well as various non-mainstream product forms such as smart clothing, backpacks, crutches, accessories, etc.

[0003] Wearable devices require electrical connectors. Currently, the electrical connectors used on wearable devices are all contact PIN pins. The main structure of this contact PIN pin includes a base, a contact portion, and a connecting portion; the contact portion and the connecting portion are both integrally extended from the base. When in use, the base is fixed together with the device housing by inlay molding, the contact portion is exposed outside the device housing and is used to contact the external mechanism, and the connecting portion is exposed inside the device housing and is used to connect to the internal mechanism. However, in the prior art, the upper and lower surfaces of the base are both horizontal planes, and the peripheral side surfaces of the base are vertical planes, which cannot form a waterproof path, making it easy for external water vapor to penetrate into the interior of the device from the horizontal and vertical surfaces. The waterproof effect is poor and cannot meet the needs of use. Therefore, it is necessary to improve the current contact PIN pins. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a waterproof contact PIN needle structure for wearable devices, which can effectively solve the problem that the existing contact PIN needle cannot form a waterproof path, making it difficult for the device to achieve waterproofing.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A waterproof contact PIN structure for a wearable device, which is entirely made of conductive material and includes a base, a contact portion, and a connecting portion; the contact portion and the connecting portion both extend integrally from the base; an annular groove is concavely formed on the outer peripheral side surface of the base, and a recess is concavely formed on the upper surface of the base; the contact portion extends upward integrally from the center of the bottom surface of the recess, and the height of the contact portion is greater than the depth of the recess; the connecting portion extends downward integrally from the center of the lower surface of the base.

[0007] As a preferred solution, the base is disc-shaped, and the annular groove is located in the middle of the outer peripheral side of the base.

[0008] As a preferred solution, the cross section of the annular groove is arc-shaped.

[0009] As a preferred solution, the concave portion is a circular concave portion.

[0010] As a preferred solution, the contact portion is a circular cylindrical structure with a simple structure and good conductive effect.

[0011] As a preferred solution, the connecting portion is a circular cylindrical structure with a simple structure and good conductive effect.

[0012] As a preferred solution, the base, contact part and connecting part are coaxially arranged, and the outer diameter of the contact part is larger than the outer diameter of the connecting part, so as to better ensure that the product is firmly and reliably installed with the equipment housing, the contact part is in stable contact with the external mechanism, and the connecting part is reliably connected with the internal mechanism.

[0013] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0014] By providing an annular groove on the outer peripheral side surface of the base and providing a concave position on the upper surface of the base, a waterproof path can be formed using the annular groove and the concave position, which greatly extends the flow range of water vapor and makes it more difficult for water vapor to enter the interior of the device, thereby achieving a good waterproof effect, meeting the needs of use, and bringing convenience to use.

[0015] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments: BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 to 4 As shown, it shows the specific structure of a preferred embodiment of the present invention, which is made of conductive material (such as metal, etc.) as a whole and includes a base 10, a contact portion 20 and a connecting portion 30.

[0026] The outer circumferential side surface of the base 10 is provided with an annular groove 11, and the upper surface of the base 10 is provided with a recessed portion 12. In this embodiment, the base 10 is disc-shaped, and the annular groove 11 is located in the middle of the outer circumferential side surface of the base 10, resulting in a simple structure and ease of manufacture. The annular groove 11 has an arc-shaped cross-section, which is simple in structure and better blocks water vapor from entering, achieving a better waterproof effect. Furthermore, the recessed portion 12 is a circular recessed portion, which is simple in structure and easy to manufacture.

[0027] The contact portion 20 integrally extends from the base 10 and is used to contact an external device. Specifically, the contact portion 20 integrally extends upward from the center of the bottom surface of the recess 12. The height of the contact portion 20 is greater than the depth of the recess 12, to facilitate better contact and conduction with the external device. In this embodiment, the contact portion 20 is a circular cylindrical structure with a simple structure and good conductivity. The top surface of the contact portion 20 is a contact surface 21, which is a circular horizontal surface, providing stable and reliable contact with the external device.

[0028] The connecting portion 30 is integrally extended from the base 10. Specifically, the connecting portion 30 is integrally extended downward from the center of the lower surface of the base 10 to better connect and conduct with the internal mechanism. In this embodiment, the connecting portion 30 is a circular cylindrical structure with a simple structure and good conductive effect.

[0029] In addition, the base 10, contact portion 20, and connecting portion 30 are coaxially arranged, and the outer diameter of the contact portion 20 is larger than that of the connecting portion 30. This ensures that the product is securely and reliably mounted on the device housing 40, that the contact portion 20 maintains stable contact with external components, and that the connecting portion 30 is reliably connected to internal components. Furthermore, the length of the connecting portion 30 is greater than that of the contact portion 20, making connection easier.

[0030] The method of using this embodiment is described in detail as follows:

[0031] When in use, the product is placed in an injection mold, and then the device housing 40 is injection molded, such as Figure 4As shown, the plastic material of the device housing 40 fills the annular groove 11 and the recess 12. Water vapor outside the contact portion 20 needs to pass around the inner wall of the recess 12 and the annular groove 11 to enter the device housing 40. The setting of the recess 12 and the annular groove 11 greatly extends the flow path of water vapor, making it more difficult for water vapor to enter the interior of the device, thereby achieving a better waterproof effect.

[0032] The design focus of the present utility model is that an annular groove is provided on the outer peripheral side surface of the base, and a concave position is provided on the upper surface of the base. A waterproof path can be formed by utilizing the annular groove and the concave position, which greatly extends the flow range of water vapor and makes it more difficult for water vapor to enter the interior of the device, thereby achieving a good waterproof effect, meeting the needs of use, and bringing convenience to use.

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
