Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a Type-C connector used in the field of electrical devices. Background Technology

[0002] In today's digital age, Type-C connectors, with their compact size, reversible pluggability, and powerful data and power transmission capabilities, have become the mainstream interface for various electronic devices. From smartphones and tablets to laptops, from smart home devices to industrial control equipment, Type-C connectors are widely used in consumer electronics, industry, medical and many other fields, greatly improving the interoperability between devices and the user experience.

[0003] Chinese patent CN214850552U discloses a mobile phone charger that effectively prevents connector breakage. It includes a charger body and a charging cable mounted on the charger body. One end of the charging cable has a first connector, and the other end has a second connector. The charging cable also includes an anti-breakage device. Both the first and second rubber sleeves have transition sleeves at their ends. These transition sleeves are hollow frustum-shaped, with a rubber ring at their front end. A plastic mesh tube is positioned between the two rubber rings, and a return spring is positioned between the end of the plastic mesh tube and the rubber rings. This invention effectively prevents connector breakage, is convenient to use, and brings convenience to users.

[0004] When users travel with electronic devices, the Type-C connector may be squeezed by other items in a backpack, or excessive force may be applied during plugging and unplugging, which may cause the connector interface to deform and the internal pins to be damaged. This can affect the stability of data transmission and power supply, and even cause the device to malfunction. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when users carry electronic devices, the Type-C connector may be squeezed by other items in the backpack, or excessive force may be used during plugging and unplugging, which may cause the connector interface to deform and the internal pins to be damaged, thereby affecting the stability of data transmission and power supply, or even causing the device to malfunction.

[0006] To address the aforementioned issues, this utility model provides a Type-C connector, comprising a connector body, an electrical connector fixedly connected to the front end of the connector body, an electrical groove electrically inserted into the front end of the electrical connector, side mating plates fixedly connected to the left and right ends of the connector body, a strip-shaped groove formed at the end of the side mating plate away from the connector body, a self-resetting sliding block slidably connected to the inner end of the strip-shaped groove, a spring connector fixedly connected between the self-resetting sliding block and the strip-shaped groove, a frame-shaped protective cover fixedly connected to the ends of the two self-resetting sliding blocks away from each other, the frame-shaped protective cover covering the outside of the connector body, the frame-shaped protective cover being made of a transparent and visible material, an extension wire fixedly connected to the rear end of the connector body, and multiple evenly distributed heat dissipation holes symmetrically formed at the upper and lower ends of the frame-shaped protective cover.

[0007] In the aforementioned Type-C connector, this solution, through the cooperation of a frame-type protective cover, a self-resetting sliding block, and a spring connector, provides space for the mating of the electrical connector and the electrical groove when the connector body is connected to an external device, and can be re-covered for protection when pulled out, reducing the pressure and wear of external forces on the electrical connector.

[0008] As a further improvement of this application, a thermally conductive coating is fixedly connected to the inner wall of the heat dissipation hole, and the heat dissipation hole and the thermally conductive coating cooperate with the connector body.

[0009] As a further improvement of this application, the length of the frame-type protective cover is greater than the total length of the connector body and the electrical connector, and the frame-type protective cover abuts against the electrical groove.

[0010] As a further improvement of this application, a linkage back plate is fixedly connected to the rear end of the frame-type protective cover, and an annular sliding sleeve is fixedly connected to the middle of the linkage back plate.

[0011] As a further improvement to this application, the rear end of the annular sleeve is provided with a plurality of annularly arranged deformation mechanical bars, which are evenly distributed on the outer side of the extended conductor.

[0012] As a further improvement to this application, hinges are installed at the front, middle and rear positions of multiple deformable mechanical bars, and limit rings are installed on the outside of the multiple hinges located on the rear side.

[0013] As a further improvement to this application, the limiting ring is fixedly connected to the outside of the extension wire away from the connector body, and the annular sliding sleeve is slidably connected to the outside of the extension wire near the connector body.

[0014] In summary, this solution, through the cooperation of a frame-type protective cover, a self-resetting sliding block, and a spring connector, provides space for the mating of electrical connectors and electrical grooves when the connector body is connected to external equipment. Furthermore, it can be re-covered for protection when pulled out, reducing external force on the electrical connectors and reducing wear, thus ensuring connection accuracy. Regarding heat dissipation, the heat dissipation holes on the frame-type protective cover and the thermally conductive coating on the inner side effectively increase the contact area with air, promoting air convection and achieving efficient heat dissipation for the connector body. In addition, the synergistic effect of the linkage backplate, annular sliding sleeve, deformable mechanical bar, limiting ring, and hinge allows the connection point between the extension wire and the connector body to be separated from the base surface during use, reducing friction and increasing the contact area with air, further improving the heat dissipation effect of key connection points.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-5 A Type-C connector is shown, including a connector body 1. An electrical connector 2 is fixedly connected to the front end of the connector body 1. An electrical groove 3 is electrically inserted into the front end of the electrical connector 2. Side mating plates 4 are fixedly connected to the left and right ends of the connector body 1. A strip groove 5 is opened at the end of the side mating plate 4 away from the connector body 1. A self-resetting sliding block 7 is slidably connected to the inner end of the strip groove 5. A spring connector 6 is fixedly connected between the self-resetting sliding block 7 and the strip groove 5. A frame-shaped protective cover 8 is fixedly connected to the ends of the two self-resetting sliding blocks 7 that are far apart from each other. The frame-shaped protective cover 8 covers the outside of the connector body 1. The frame-shaped protective cover 8 is made of a transparent material. An extension wire 9 is fixedly connected to the rear end of the connector body 1. Multiple evenly distributed heat dissipation holes 10 are symmetrically opened at the upper and lower ends of the frame-shaped protective cover 8.

[0027] Figures 3-5 The inner wall of the heat dissipation hole 10 is fixedly connected with a thermally conductive coating 17. The heat dissipation hole 10 and the thermally conductive coating 17 cooperate with the connector body 1. The length of the frame-shaped protective cover 8 is greater than the total length of the connector body 1 and the electrical connector 2. The frame-shaped protective cover 8 abuts against the electrical groove 3.

[0028] Figures 1-5This diagram illustrates that when connecting the connector body 1 to an external device, the electrical connector 2 is aligned with the electrical recess 3 for insertion. During the advancement of the connector body 1, because the front end of the frame-type protective cover 8 abuts against the surface of the device containing the electrical recess 3, the frame-type protective cover 8 cannot move forward synchronously with the connector body 1. At this time, the connector body 1 continues to advance, causing the self-resetting sliding block 7 on the side mating plate 4 to slide within the strip groove 5. The self-resetting sliding block 7 compresses the spring connector 6, placing it in a compressed state. As the spring connector 6 is compressed, the frame-type protective cover 8 gradually moves backward, thus creating space for the electrical connector 2 to mate with the electrical recess 3 until the two are electrically connected. During the use of the Type-C connector, the heat generated by the connector body 1 is transferred through heat conduction. The heat is transferred to the frame-type protective cover 8. Since the inner wall of the heat dissipation hole 10 is provided with a thermally conductive coating 17, the heat can be conducted to the heat dissipation hole 10 more efficiently. The heat dissipation hole 10 increases the contact area between the frame-type protective cover 8 and the outside air, promotes air convection, and allows the heat to be dissipated into the surrounding environment, thereby achieving heat dissipation for the connector body 1. When it is necessary to pull out the connector body 1, the pushing force on the connector body 1 is released, and the spring connector 6 in the compressed state releases its elastic potential energy, pushing the self-resetting sliding block 7 to slide in the opposite direction in the strip groove 5, driving the frame-type protective cover 8 to move forward until the frame-type protective cover 8 covers the electrical connector 2 and the front end of the connector body 1 again, providing protection for the electrical connector 2, reducing the pressure and wear of external forces on it, and reducing the risk of decreased connection accuracy due to collision or pressure.

[0029] Second implementation method:

[0030] Figure 3 , Figures 6-7 A Type-C connector is shown. A linkage backplate 12 is fixedly connected to the rear end of a frame-type protective cover 8. An annular sliding sleeve 13 is fixedly connected to the middle of the linkage backplate 12. A plurality of annularly arranged deformation mechanical bars 14 are provided at the rear end of the annular sliding sleeve 13. The plurality of deformation mechanical bars 14 are evenly distributed on the outer side of the extension wire 9. A hinge 16 is installed on the front, middle and rear sides of the plurality of deformation mechanical bars 14. A limiting ring 15 is installed on the outside of the plurality of hinges 16 on the rear side. The limiting ring 15 is fixedly connected to the outer side of the extension wire 9 at a position away from the connector body 1. The annular sliding sleeve 13 is slidably connected to the outer side of the extension wire 9 at a position close to the connector body 1.

[0031] Figure 3 , Figures 6-7As the frame-type protective cover 8 moves, the linkage back plate 12, which is fixedly connected to its rear end, moves synchronously. The annular sliding sleeve 13 in the middle of the linkage back plate 12 slides outside the extension wire 9. When the annular sliding sleeve 13 slides backward, it pulls the deformation mechanical bar 14. Since the deformation mechanical bar 14 is connected by the hinge 16 and its rear end is fixed to the extension wire 9 by the limiting ring 15, under the pull of the annular sliding sleeve 13, the deformation mechanical bar 14 bends through the hinge 16, causing the connection position between the extension wire 9 and the connector body 1 to be lifted upward and separated from the contact base surface, reducing the direct friction between the extension wire 9 and the base surface, and also increasing the contact area between the connection part and the air, further improving the heat dissipation effect of this key part. When the frame-type protective cover 8 returns to its original position, the annular sliding sleeve 13 slides forward, and the deformation mechanical bar 14 returns to its original position under its own weight and structural constraints.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
