Description
Technical Field
[0001] This utility model relates to the field of plug technology, and in particular to a watch charging data transmission plug structure and a watch. Background Technology
[0002] When using smartwatches, charging is often necessary to extend battery life, and a data cable connects the watch to external devices for data updates. To simplify smartwatch components, charging and data transfer currently share a single connection point, using magnetic pins or springs to provide electrical contact between the watch and an external connector. However, because this magnetic connection is weak, the attraction between the watch and connector is limited during charging or data transfer. When the connector is subjected to external force, it can easily detach from the watch contacts, leading to poor contact and affecting normal charging and data transfer. Furthermore, the magnetic connection requires the connection point to be made of ferromagnetic material. After prolonged wear, this material is susceptible to corrosion from sweat or environmental oxidation, affecting the watch's appearance. Utility Model Content Therefore, it is necessary to address the above-mentioned shortcomings by disclosing a watch charging data transmission plug structure and a watch that provides a non-magnetic connection structure, ensures a firm connection between the watch and the connector, and breaks through the limitations of magnetic connection materials.
[0003] A watch charging data transmission plug structure is provided for fixing to the inner side of the watch case back, wherein the outer side of the watch case back is recessed to form a connection groove for inserting an external charging transmission female connector; the watch charging data transmission plug structure includes: The main body is fixed to the inner side of the watch case, and the main body has through holes that penetrate the front and rear sides of the main body. A fixing sleeve is fixed to the front side of the main body, which passes through the watch case and is inserted into the connecting groove. The fixing sleeve communicates with the through hole. Each of the two opposite outer sides of the fixing sleeve has at least one protrusion for engaging with the snap hole in the charging transmission socket. An insulating bracket is fitted inside the fixed sleeve and is tightened to fit the inner wall of the fixed sleeve. The insulating bracket has multiple mounting holes that penetrate the front and rear sides of the insulating bracket and are arranged side by side. The pin assembly includes a plurality of pins that pass through each mounting hole in a one-to-one correspondence. The front end of each pin forms a first connection portion for electrical connection with the contacts of the charging transmission socket, and the rear end of each pin forms a second connection portion for electrical connection with the watch circuit board.
[0004] In one embodiment, the front end face of the fixed sleeve is provided with a first limiting groove that communicates with the inner cavity of the fixed sleeve and forms a first step at the front end of the fixed sleeve. The insulating bracket includes a frame body that is inserted into the inner cavity of the fixed sleeve and a first flange that is fixed to the front edge of the frame body and abuts against the first step. The rear end of the frame body has a frustum portion, and the width of the frustum portion gradually decreases from the front end of the frame body to the rear end of the frame body.
[0005] In one embodiment, the inner surface of the fixing sleeve is provided with an annular protrusion near the rear end of the fixing sleeve, and the side of the annular protrusion facing the front side of the fixing sleeve forms a limiting platform that abuts against the rear end of the frame.
[0006] In one embodiment, the front end of the insulating bracket has a second limiting groove that corresponds to and connects to each mounting hole. Each second limiting groove is coaxial with its corresponding mounting hole and forms a second step at the front end of the mounting hole. A second flange that abuts against the second step is formed at the first connecting part of the pin.
[0007] In one embodiment, the pin is provided with a plurality of annular grooves spaced apart along the pin axial direction to form the second connecting portion.
[0008] In one embodiment, the pin includes a copper post, a platinum layer fixed to the front end of the copper post, and a gold layer fixed to the rear end of the copper post, with the platinum layer forming the first connecting portion.
[0009] In one embodiment, the front side of the main body is provided with an annular groove surrounding the fixing sleeve, and a sealing ring that abuts against the inner side of the watch case is fixed in the annular groove; at least two elastic sealing protrusions are concentrically arranged on the front side of the sealing ring surrounding the fixing sleeve; the main body is connected to the watch case with screws.
[0010] In one embodiment, the protrusion has a frustoconical structure on the outer side of the fixing sleeve, and the width of the protrusion gradually decreases in the direction away from the inner cavity of the fixing sleeve.
[0011] In one embodiment, the main body is made of 304 or 316L stainless steel, and the insulating support is made of polycarbonate.
[0012] This utility model also discloses a watch that includes the above-described watch charging data transmission plug structure.
[0013] The watch charging data transmission plug structure and watch implementing this utility model, through a fixing sleeve inserted into the connecting groove, form a protrusion that engages with the charging transmission female socket in the connecting groove. Furthermore, the protrusion on the outer surface of the fixing sleeve engages with the retaining hole in the charging transmission female socket, further restricting the relative position of the plug structure and the charging transmission female socket. This replaces the traditional magnetic connection between the watch and the charging transmission female socket, improving the connection strength and ensuring stable charging and data transmission. In addition, by eliminating the magnetic connection, the main body supporting the pins at the watch connection point can be made of non-ferromagnetic material. This non-magnetic connection structure breaks the limitations of magnetic connection materials, avoiding the problem of the main body being corroded by sweat or oxidized by the environment, thus helping to maintain the appearance of the watch connection point.

Detailed Implementation
[0015] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0016] Example 1 Please combine Figure 1-6This utility model discloses a watch charging and data transmission plug structure that provides a non-magnetic connection structure, ensures a firm connection between the watch and the connector, and breaks the limitations of magnetic connection materials. This watch charging and data transmission plug structure is used to fix the watch to the inner side of the watch case 10 (i.e., the side of the watch case 10 facing away from the inner side of the case) and forms the watch's charging and data transmission position on the outer side of the watch case 10 (i.e., the side of the watch case 10 facing away from the inner side of the case). The outer side of the watch case 10 is recessed to form a connection groove 101 for inserting an external charging and data transmission female connector 20. The external charging and data transmission female connector 20 is a connector used to connect to the watch's charging and data transmission position and to charge or transmit data to the watch. The charging and data transmission female connector 20 has a female head that inserts into the connection groove 101, a slot 201 on the female head, a locking hole 202 on the side of the slot 201, and a contact point inside the slot 201. The watch charging data transmission plug structure includes a main body 100, an insulating bracket 200, and a pin assembly. The main body 100 is fixed to the inner side of the watch case 10, and the main body 100 has through holes 110 penetrating the front and rear sides of the main body 100. A fixing sleeve 120 is fixed to the front side of the main body 100, passing through the watch case 10 and inserted into the connecting groove 101. The fixing sleeve 120 communicates with the through hole 110, and the fixing sleeve 120 and the through hole 110 on the main body 100 are coaxial. It can be understood that the main body 100 has an overall T-shaped structure. In this way, while ensuring that the fixing sleeve 120 can form a "male head" for insertion into the slot 201 in the connecting groove 101, the fixing connection between the main body 100 and the inner side of the watch case 10 achieves the positioning of the fixing sleeve 120. Each of the two opposite outer surfaces of the fixing sleeve 120 is provided with at least one protrusion 121 for engaging with the locking hole 202 in the charging transmission female socket 20. Thus, when the fixing sleeve 120 is inserted into the connecting groove 101, an annular mounting area is formed in the connecting groove 101 on the outer side of the fixing sleeve 120. After the female head of the charging transmission female socket 20 is inserted into this annular mounting area, on the one hand, the engagement between the female head and the connecting groove 101 and the fixing sleeve 120 prevents the charging transmission female socket 20 from shaking in the plane of the outer side of the watch case 10. On the other hand, the engagement between the protrusion 121 on the fixing sleeve 120 and the locking hole 202 on the charging transmission female socket 20 restricts the displacement of the charging transmission female socket 20 along the thickness direction of the watch, thereby preventing the charging transmission female socket 20 from falling off the watch and improving the stability of the connection between the charging transmission female socket 20 and the watch. The insulating bracket 200 is embedded in the fixed sleeve 120 and is tightly fitted with the inner wall of the fixed sleeve 120. The insulating bracket 200 has multiple mounting holes 210 that penetrate the front and rear sides of the insulating bracket 200 and are arranged side by side.The pin assembly includes a plurality of pins 300 that pass through each mounting hole 210. The front end of each pin 300 forms a first connecting portion 310 for electrical connection with the contacts of the charging transmission socket 20. The front end face of the pin 300 is concave to increase the contact area when the pin 300 is connected to the contacts of the charging transmission socket 20. The rear end of each pin 300 forms a second connecting portion for electrical connection with the watch circuit board. In this embodiment, the insulating bracket 200 is used to position each pin 300 and to achieve insulation between adjacent pins 300 and between the pin 300 and the main body 100, so as to ensure that each pin 300 independently transmits current or electrical signals. It should be noted that in this embodiment, the front end or front side of each component refers to the end or side of the component facing away from the inside of the watch case 10, and the rear end or rear side of each component refers to the end or side of the component facing the inside of the watch case 10. This interpretation can be used in all embodiments.
[0017] The main body 100 provides support for its various components and, through its cooperation with the charging transmission female connector 20, achieves mechanical positioning between the watch and the charging transmission female connector 20. In this embodiment, the main body 100 is made of 304 or 316L stainless steel and is manufactured from 304 or 316L stainless steel using MIM (Metal Injection Molding) technology. This ensures the strength and precision of the main body 100 while preventing oxidation and environmental corrosion. The rear side of the main body 100 is provided with reinforcing ribs 130 surrounding the through hole 110 to improve the mechanical strength of the main body 100 and prevent the fixing sleeve 120 from shaking or even detaching from the main body 100 under the action of the charging transmission female connector 20.
[0018] Please combine Figure 1-7In one embodiment, the main body 100 and the fixing sleeve 120 are integrally formed to improve the stability of their connection. The front side of the main body 100 has an annular groove 140 surrounding the fixing sleeve 120. A sealing ring 150, which abuts against the inner side of the watch case 10, is fixed within the annular groove 140. The outer contour of the sealing ring 150 is adapted to the inner contour of the annular groove 140. The sealing ring 150 can be embedded into the annular groove 140 by adhesive bonding or tightening to fix it. Since the fixing sleeve 120 passes through the watch case 10 and inserts into the connecting groove 101, the bottom surface of the connecting groove 101 has a through hole 102 communicating with the inner side of the watch case 10. By providing the sealing ring 150 on the main body 100, the sealing ring 150 can surround the through hole 102 to prevent external water from entering the watch through the through hole 102, ensuring the watch's waterproof effect. Furthermore, in this embodiment, the front side of the sealing ring 150 is concentrically provided with at least two rings of elastic sealing protrusions 151 surrounding the fixing sleeve 120. By providing at least two rings of elastic sealing protrusions 151 on the front side of the sealing ring 150, on the one hand, the elastic sealing protrusions 151 deform when the sealing ring 150 is squeezed, thereby blocking the channel from the through hole 102 to the inside of the watch. On the other hand, by increasing the multiple layers of barriers (i.e., elastic sealing protrusions 151), the path for external water to enter the inside of the watch can be extended, which is beneficial to further improve the watch's waterproof performance.
[0019] In addition, in this embodiment, the sealing ring 150 is made of NRB nitrile rubber to ensure the overall elasticity of the sealing ring 150, making it easy to deform under compression to achieve a sealing and waterproof effect. Furthermore, the main body 100 is screwed to the watch case 10. Specifically, the main body 100 has three connecting holes 160 on each side of the fixing sleeve 120, arranged in a triangular pattern. Each connecting hole 160 contains a corresponding locking screw 161 fixedly connected to the watch case 10, thus securing the main body 100 to the watch case 10. In this way, while the main body 100 is fixed to the watch case 10 by the locking screws 161, the main body 100 moves the sealing ring 150 closer to the watch case 10, causing the sealing ring 150 to deform under the combined compression of the main body 100 and the watch case 10, thereby achieving a waterproof effect. Preferably, the locking screw 161 is a machine screw with a nominal diameter of 1.2mm (i.e., M1.2) and a thread length of 2.5mm.
[0020] To reduce the difficulty of inserting and removing the watch from the charging transmission socket 20, in one embodiment, the protrusion 121 has a frustoconical structure on the outer side of the fixing sleeve 120, and the width of the protrusion 121 gradually decreases along the direction away from the inner cavity of the fixing sleeve 120. That is, the four sides of the protrusion 121 are inclined. In this way, the inclined surface guides the smooth insertion and removal of the watch from the charging transmission socket 20, while also ensuring the amount and force of the engagement between the watch and the charging transmission socket 20. In this embodiment, the dimensions of each protrusion 121 are 0.9 x 1.4 x 0.17 mm, that is, the dimension of the protrusion 121 along the depth direction of the connecting groove 101 is 0.9 mm, the dimension of the protrusion 121 along the pin arrangement direction is 1.1 mm, and the dimension of the protrusion 121 along the width direction of the connecting groove 101 is 0.17 mm. Preferably, the fixing sleeve 120 has a racetrack-shaped structure, and two protrusions 121 are arranged side by side on each of the two opposite outer walls of the fixing sleeve 120 to increase the engagement point between the fixing sleeve 120 and the charging transmission female socket 20 and improve the connection strength between the watch and the charging transmission female socket 20.
[0021] Please combine Figure 1-9 The front end face of the fixed sleeve 120 has a first limiting groove 122 that communicates with the inner cavity of the fixed sleeve 120 and forms a first step at the front end of the fixed sleeve 120. The insulating support 200 includes a frame 220 inserted into the inner cavity of the fixed sleeve 120, a first flange 230 fixed to the front edge of the frame 220 and abutting against the first step, and a frustum 240 at the rear end of the frame 220. The width of the frustum 240 gradually decreases from the front end of the frame 220 to the rear end of the frame 220. In this way, the insulating support 200 can be limited within the fixed sleeve 120 by the abutment between the first flange 230 and the first step. At the same time, the frustum 240 at the rear end of the frame 220 reduces the difficulty of inserting the insulating support 200 into the inner cavity of the fixed sleeve 120. Furthermore, an annular protrusion 170 is provided on the inner side of the fixed sleeve 120 near the rear end of the fixed sleeve 120. A limiting platform is formed on the side of the annular protrusion 170 facing the front of the fixed sleeve 120, which abuts against the rear end of the frame 220. The limiting protrusion 170 can limit the maximum insertion depth of the insulating bracket 200 in the fixed sleeve 120. In addition, a second limiting groove 250 is provided at the front end of the insulating bracket 200, which corresponds to and connects to each mounting hole 210. Each second limiting groove 250 is coaxial with its corresponding mounting hole 210 and forms a second step at the front end of the mounting hole 210. A second flange 320 is formed at the first connecting part 310 of the pin 300, which abuts against the second step. In this way, the insertion depth of the pin 300 on the insulating bracket 200 can be limited by the cooperation of the second step and the second flange 320, so that the installation of each pin 300 is consistent.
[0022] In one embodiment, the insulating bracket 200 is made of polycarbonate. This ensures insulation between adjacent pins 300. Furthermore, due to the excellent toughness of polycarbonate, the insulating bracket 200, made of polycarbonate, adds a resilient structure between the rigid main body 100 and the pins 300, making the entire watch charging data transmission plug structure more robust. Preferably, the insulating bracket 200 is injection molded between the pins 300. During the manufacturing of the watch charging data transmission plug structure, the insulating bracket 200 is formed between the pins 300 using an overmolding process. Then, the connector formed by the pins 300 and the insulating bracket 200 is assembled into the inner cavity of the fixed sleeve 120, allowing the insulating bracket 200 to be tightly fitted to the inner wall of the fixed sleeve 120.
[0023] The pin 300 has multiple annular grooves 330 spaced apart along its axial direction to form a second connection portion. This allows the annular grooves 330 to provide an electrical connection between the pin 300 and the internal wires of the watch when the watch charging data transmission plug is electrically connected to the watch's circuit board. This helps to limit the ends of the wires and ensure the stability of the connection between the pin 300 and the watch circuit board. Furthermore, the pin 300 includes a copper pillar, a platinum layer fixed to the front end of the copper pillar, and a gold layer fixed to the rear end of the copper pillar. The platinum layer forms the first connection portion 310. Preferably, the front end of the copper pillar is plated with platinum to form a platinum layer, and the front end of the copper pillar is plated with gold to form a gold layer. This achieves both aesthetic appeal and reduced impedance, improving the conductivity of the pin 300. It should be noted that in this embodiment, the pin assembly includes five pins 300 arranged side by side. Each pin 300 is defined as a contact point that connects to the VBSU, D+, GND, D-, VBUS pins of the watch circuit board. The connecting body composed of the fixing sleeve 120, the insulating bracket 200 and the pin assembly has a centrally symmetrical structure. In this way, when the watch is connected to the external charging transmission socket 20, it can be plugged in and unplugged in either direction without the need for foolproofing, which facilitates blind insertion and improves convenience.
[0024] Example 2 This utility model also discloses a smartwatch including the above-mentioned watch charging data transmission plug structure. Specifically, the watch also includes a watch case, a circuit board and power supply housed within the watch case, a display screen fixed to the main surface of the watch case and electrically connected to the circuit board, and a watch strap connecting the watch case and restricting the watch to the user's wrist. The watch case includes a front case and a back case. The display screen is mounted on the main surface of the front case, and the back case is mounted on the back of the front case and together with the back case encapsulates the circuit board and power supply. The outer side of the back case is recessed to form a connection groove 101 for inserting an external charging transmission socket. The bottom surface of the connection groove 102 has a through hole 102 communicating with the inner cavity of the watch case. The main body 100 of the watch charging data transmission plug structure is fixed to the inner surface of the back case, and the fixing sleeve 120 passes through the through hole 102 and is inserted into the connection groove 101 to form an annular mounting area in the connection groove 101, thereby providing a charging and data transmission position for connecting to an external charging transmission socket. The main body 100 is fixedly connected to the back case by locking screws. In this embodiment, the structure of the watch charging data transmission plug is exactly the same as that in Embodiment 1, and the specific details can be found in the relevant description of Embodiment 1. When the external charging transmission female connector is engaged with the watch charging data transmission plug structure, the protrusion and the locking hole provide mechanical restraint between the charging transmission female connector and the watch. The contact between the contacts on the charging transmission female connector and the pins establishes an electrical connection between the charging transmission female connector and the watch, so that the charging transmission female connector can transmit external voltage to the watch's circuit board to charge the power supply, or transmit external electrical signals to the circuit board for data signal transmission.
[0025] The watch charging data transmission plug structure and watch implementing this utility model form a protrusion that engages with the charging transmission female socket 20 in the connecting groove 101 through a fixing sleeve 120 inserted into the connecting groove 101. The protrusion 121 on the outer surface of the fixing sleeve 120 engages with the locking hole 202 in the charging transmission female socket 20, further restricting the relative position between the plug structure and the charging transmission female socket 20. This replaces the traditional magnetic connection between the watch and the charging transmission female socket 20, improving the connection strength and ensuring stable charging and data transmission. Furthermore, by eliminating the magnetic connection, the main body 100 supporting the pin 300 at the watch connection point can be made of a non-ferromagnetic material. This non-magnetic connection structure breaks the limitations of magnetic connection materials, preventing the main body 100 from being corroded by sweat or oxidized by the environment, thus maintaining the appearance of the watch connection point.
[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0027] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
