Description

Technical Field

[0001] This utility model relates to the field of Type-C connector technology, and specifically to a Type-C connector with an adjustable fixing mechanism. Background Technology

[0002] The Type-C connector is a USB interface standard that is smaller than both Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones).

[0003] Currently, Type-C connectors generally consist of a charging cable and a Type-C interface. However, the current charging cables are directly exposed, making it impossible to rewind them or the rewinding operation is quite troublesome. This easily leads to the charging cables getting tangled, causing a mess and affecting storage and portability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a Type-C connector with an adjustable fixing mechanism, which can change the length of the charging cable by pulling it out and can automatically position the pulled-out charging cable, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: A Type-C connector with an adjustable fixing mechanism includes a housing and a cover. The Type-C connector is mounted on the housing. A slip ring is mounted at the center of the inner cavity of the housing. A bearing is mounted on the outside of the slip ring. A winding reel is mounted on the outer ring of the bearing. A spring is mounted on one side of the winding reel. The outer ring of the spring is mounted on the inner ring surface of the housing. The other side of the winding reel has a ring structure with multiple positioning grooves. One side of each positioning groove has a first guide portion with an arc structure. Positioning blocks are inserted into the positioning grooves on both sides. One side of each positioning block forms a second guide portion that contacts the first guide portion. The cover is located outside the opening of the housing. A positioning ring is mounted on the inner side of the cover. The positioning ring is inserted into the opening of the housing. An elastic retraction component is installed between the cover and the positioning blocks.

[0006] As a preferred technical solution, the elastic retraction assembly includes a slider and a first compression spring. The inner side of the cover is provided with a groove opposite to the positioning block. The slider is slidably disposed in the groove. The other end of the positioning block is bent and installed on the slider. The first compression spring is disposed in the groove. One end of the first compression spring is installed on the slider, and the other end is installed on the inner wall of the groove.

[0007] As a preferred technical solution, the Type-C connector includes a charging cable, a first Type-C interface, and a second Type-C interface. A shaft hole is provided on the outer ring surface of the housing. One end of the charging cable is installed on a reel, and the core of the charging cable is installed on a rotatable terminal of the slip ring. The other end of the charging cable extends through the shaft hole to the outside and is fixedly connected to the first Type-C interface. A fixing seat is installed on one side of the outer ring of the housing located at the shaft hole. The second Type-C interface is installed on the fixing seat. A cable is installed on the fixed terminal of the slip ring. A wiring channel communicating with the fixing seat is formed inside the outer wall of the housing. The other end of the cable passes through the wiring channel and is fixedly connected to the second Type-C interface.

[0008] As a preferred technical solution, the shell has multiple positioning holes on the open end face, and positioning pins are installed on the inner side of the shell cover opposite the positioning holes. The other end of each positioning pin is inserted into the positioning hole and a second compression spring is installed on each of them. The other end of each second compression spring is installed on the inner wall of the positioning hole.

[0009] As a preferred technical solution, the bearing is made of plastic material.

[0010] As a preferred technical solution, both the groove and the slider have trapezoidal cross-sections.

[0011] The beneficial effects of this utility model are as follows: This utility model has a simple structure. After the charging cable is pulled outward, the reel can rotate clockwise. The compression between the first and second guide parts allows the positioning block to move outward automatically, and the reel can rotate smoothly, allowing the charging cable to be pulled out smoothly. After the position is determined, the rebound of the first compression spring allows the positioning block to be inserted into the positioning groove. Since the other side of the positioning block is provided with a guide structure, the reel cannot rotate in the opposite direction, thereby fixing the pulled-out charging cable to adapt to different usage situations. After the shell cover is squeezed, the positioning block can be disengaged from the positioning groove. The twisting of the spring can rewind the released charging cable into the inside of the shell in one go, greatly facilitating the operation. Attached Figure Description

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a Type-C connector with an adjustable fixing mechanism, comprising a housing 4 and a cover 5. The Type-C connector is mounted on the housing 4. A collector ring 8 is mounted at the center of the inner cavity of the housing 4. A bearing 9 is mounted on the outside of the collector ring 8. A winding reel 13 is mounted on the outer ring of the bearing 9. A spring 14 is mounted on one side of the winding reel 13. The outer ring of the spring 14 is mounted on the inner ring surface of the housing 4. The other side of the winding reel 13 has a plurality of positioning grooves 10 in an annular structure. Each positioning groove 10 has a first guide portion 11 with an arc-shaped structure on one side. Positioning blocks 12 are inserted into the positioning grooves 10 on both sides. Each positioning block 12 has a second guide portion 15 on one side that contacts the first guide portion 11. The cover 5 is located outside the opening of the housing 4. A positioning ring 7 is mounted on the inner side of the cover 5 and inserted into the opening of the housing 4. An elastic retraction component is installed between the cover 5 and the positioning block 12.

[0022] In this embodiment, each elastic retraction component includes a slider and a first compression spring 16. The inner side of the cover 5 is provided with a groove opposite to the positioning block 12. The sliders are all slidably disposed in the groove. The other end of the positioning block 12 is bent and installed on the slider. The first compression spring 16 is all disposed in the groove. One end of the first compression spring 16 is installed on the slider, and the other end is installed on the inner wall surface of the groove.

[0023] In this embodiment, the Type-C connector includes a charging cable 1, a first Type-C interface 2, and a second Type-C interface 3. The outer ring surface of the housing 4 is provided with a shaft hole. One end of the charging cable 1 is installed on the winding reel 13, and the core of the charging cable 1 is installed on the rotatable terminal of the collector ring 8. The other end of the charging cable 1 extends through the shaft hole to the outside and is fixedly connected to the first Type-C interface 2. A fixing seat is installed on one side of the outer ring of the housing 4 located at the shaft hole. The second Type-C interface 3 is installed on the fixing seat. A cable is installed on the fixed terminal of the collector ring 8. A wiring channel communicating with the fixing seat is formed inside the outer wall of the housing 4. The other end of the cable passes through the wiring channel and is fixedly connected to the second Type-C interface 3.

[0024] When the reel is driven by the charging cable, the wire cores on the charging cable can rotate around the rotatable terminal, preventing the wire cores from breaking due to pulling.

[0025] In this embodiment, the shell 4 has multiple positioning holes on its open end face. The inner side of the shell cover 5 is equipped with positioning pins 6 opposite to the positioning holes. The other end of each positioning pin 6 is inserted into the positioning hole and is equipped with a second compression spring. The other end of each second compression spring is installed on the inner wall of the positioning hole. The positioning pins can position the shell cover and the shell, and the second compression springs can automatically return the squeezed shell cover to its original position.

[0026] In this embodiment, the bearing 9 is made of plastic material, which insulates the bearing, prevents electrical conductivity, and increases safety.

[0027] In this embodiment, both the slide and the slider have trapezoidal cross-sections, which allows the slider and the positioning block to move back and forth along the slide, preventing the slider from detaching from the slide.

[0028] In use, the charging cable can be pulled out to the required length. No other operation is required when pulling; simply pull the charging cable outward. As the charging cable moves, it drives the reel to rotate clockwise. During the clockwise rotation, the first guide section will push the second guide section outward, giving the positioning block an outward thrust. The positioning block can move outward along the slide groove and out of the positioning slot, allowing the reel to rotate smoothly and the charging cable to be pulled out smoothly. After being pulled out to the appropriate length, the rebound of the first compression spring will insert the positioning block into the corresponding positioning slot. Since there is no guide structure on the other side of the positioning slot and the other side of the positioning block, the reel cannot rotate counterclockwise, thus automatically fixing the pulled-out charging cable.

[0029] When it is necessary to retract the entire charging cable, the cover can be squeezed towards the housing. The movement of the cover moves the positioning block, causing it to move out of the positioning slot. After the obstruction of the positioning block and the pulling force on the charging cable are removed, the torsion of the spring can drive the winding reel to rotate counterclockwise, thereby winding the charging cable onto the winding reel. After the cover is released, the rebound of the second compression spring can return the cover to its original position and insert the positioning block into the corresponding positioning slot, thus completing the return of the positioning block and facilitating subsequent operations.

[0030] The diameter of the cap matches the diameter of the shell, making it easy to squeeze during operation and thus more convenient to operate.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
