Description

Technical Field

[0001] This utility model relates to the field of conductive connection equipment technology, and in particular to a fast extender for mobile phone charging cables. Background Technology

[0002] Charging cables, also known as power cords, are electrical wires that transmit current, typically point-to-point. Power cords can be categorized into AC (alternating current) and DC (direct current) power cords based on their application. The structure of a power cord mainly consists of an outer sheath, an inner sheath, and a conductor, commonly made of copper or aluminum wire. Mobile phone charging cables are essential accessories connecting the phone to a power source, used for charging the phone or transmitting data. There are three main types of mobile phone charging cables: Apple Lightning cables, Android micro-USB cables, and Type-C cables. Each type has its unique characteristics and applicable scenarios. Currently, mobile phone charging cables are often too short during charging, as they are all of fixed length and cannot be extended according to actual charging needs, making them inconvenient to use. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a fast extender for mobile phone charging cables.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fast extender for mobile phone charging cables includes a housing and a connector. The connector is fixed to the left side inside the housing, and a protective sleeve is fixed to the right side of the housing. A central rod is fixed inside the housing, and a rewind spring is fixed to the outer wall of the central rod. A take-up reel is connected to the outer side of the rewind spring, and an extension cable is fixedly connected to the outer side of the take-up reel. A connector is fixed to the rightmost side of the extension cable. Extension plates are fixed to the front and rear ends of the left side of the connector, and buffer springs are fixedly connected to the left side of each extension plate. A protective sleeve is nested on the right side of the extension cable. An operating panel is embedded in the upper part of the housing, and an anti-slip plate is fixed to the bottom of the operating panel.

[0006] Preferably, the outer wall of the operating disc is connected to the upper inner wall of the outer casing by a thread, and the bottom end of the anti-slip disc below the operating disc is in close contact with the upper surface of the take-up reel.

[0007] Preferably, the center rod is embedded in the middle of the take-up reel, the outer wall of the center rod is in close contact with the middle of the take-up reel, and the take-up reel rotates horizontally on the outside of the center rod.

[0008] Preferably, the connector is embedded in the sheath, and the electrical connector is electrically connected to the connector via an extension cable.

[0009] Preferably, the front and rear ends of the right side of the protective sleeve are provided with extension slots, and the extension plates of the front and rear ends of the left side of the connector are precisely embedded in the extension slots of the protective sleeve.

[0010] Preferably, the protective sleeve is fixedly connected to the left side of the buffer spring, the vertical cross-sectional area of ​​the extension groove is the same as the vertical cross-sectional area of ​​the extension plate, the left side of the protective sleeve is close to the right side of the outer shell, and the protective sleeve is made of rubber material.

[0011] 1. By pulling the connector to the right, the connector pulls the extension cable to rotate outside the take-up reel, loosening the extension cable wound around the outside of the reel. During the rotation of the reel, the return spring on the outside of the central rod will deform. After the extension cable is extended, rotate the operating disc above the outer casing. When the operating disc rotates, it pushes the anti-slip plate at the bottom down to fit tightly against the upper surface of the take-up reel, thus limiting the reel and preventing it from being accidentally pulled back after the extension cable is extended. This allows the charging cable to be extended according to the actual charging status of the mobile phone, making it more convenient to use.

[0012] 2. When the rewind spring returns to its original position and pulls the take-up reel to rotate and rewind the extension cable, the protective sleeve on the left side of the connector will make contact with the right side of the outer casing beforehand. At this time, the connector, which is still being pulled by the extension cable, will push the extension plate into the protective sleeve, compressing the buffer spring in the protective sleeve. The deformation of the buffer spring will buffer the tension on the connector, preventing the connector from directly hitting the right side of the outer casing and causing damage to the connector or detaching from the right side of the extension cable. This provides good protection for the connector. Attached Figure Description

[0018] 1. Outer casing, 101 electrical connector, 102 protective sleeve, 2. Center rod, 201 rewind spring, 202 take-up reel, 203 extension cable, 204 connector, 205 extension plate, 206 buffer spring, 207 protective sleeve, 3. Control panel, 301 anti-slip disc. Detailed Implementation

[0019] Example 1, referring to Figure 1-4 A fast extender for mobile phone charging cables includes a housing 1 and a connector 101. The connector 101 is fixed inside the left side of the housing 1. The protective sleeve 102 is fixed to the right side of the housing 1. A central rod 2 is fixed inside the housing 1. A rewind spring 201 is fixed to the outer wall of the central rod 2. A take-up reel 202 is connected to the outer side of the rewind spring 201. An extension cable 203 is fixed to the outer side of the take-up reel 202. A connector 204 is fixed to the rightmost side of the extension cable 203. Extension plates 205 are fixed to the front and rear ends of the left side of the connector 204. Buffer springs 206 are fixed to the left side of each extension plate 205. A protective sleeve 207 is nested on the right outer side of the extension cable 203. An operation disc 3 is embedded in the upper part of the inside of the housing 1. An anti-slip disc 301 is fixed to the bottom of the operation disc 3.

[0020] The outer wall of the operation panel 3 is connected to the upper inner wall of the outer casing 1 by threads, and the bottom end of the anti-slip plate 301 below the operation panel 3 is in close contact with the upper surface of the take-up reel 202.

[0021] The center rod 2 is embedded in the middle of the take-up reel 202, and the outer wall of the center rod 2 is in close contact with the middle of the take-up reel 202. The take-up reel 202 rotates horizontally on the outside of the center rod 2.

[0022] When the connector 204 is pulled to the right, the connector 204 pulls the extension cable 203 to rotate outside the take-up reel 202, thereby loosening the extension cable 203 wound around the outside of the take-up reel 202. During the rotation of the take-up reel 202, the return spring 201 on the outside of the middle rod 2 will deform. At this time, the connector 204 is released, and the return spring 201 pulls the take-up reel 202 to rotate outside the middle rod 2 to return to its original position, so that the take-up reel 202 pulls the extension cable 203 to wrap around its outer wall.

[0023] After the extension cable 203 is extended, the operating disc 3 is rotated above the outer shell 1. When the operating disc 3 rotates, it pushes the anti-slip disc 301 at the bottom to move down and stick to the upper surface of the take-up reel 202 to limit the take-up reel 202 and prevent the take-up reel 202 from being accidentally pulled back after the extension cable 203 is extended. This allows the charging cable to be extended according to the actual charging situation of the mobile phone, making it more convenient to use.

[0024] The connector 204 is perfectly embedded in the sheath 102, and the connector 101 is electrically connected to the connector 204 via the extension cable 203.

[0025] After inserting one end of the mobile phone charging cable into the connector 101, insert the connector 204 at the other end of the extension cable 203 into the charging port of the mobile phone to enable normal charging of the mobile phone.

[0026] Example 2 differs from Example 1 in that, in this example, the front and rear ends of the right side of the protective sleeve 207 are provided with extension slots, and the extension plates 205 of the left front and rear ends of the connector 204 are precisely embedded in the extension slots of the protective sleeve 207.

[0027] The protective sleeve 207 is fixedly connected to the left side of the buffer spring 206. The vertical cross-sectional area of ​​the extension groove is the same as the vertical cross-sectional area of ​​the extension plate 205. The left side of the protective sleeve 207 is close to the right side of the outer shell 1. The protective sleeve 207 is made of rubber material.

[0028] When the rewind spring 201 returns to its original position and pulls the take-up reel 202 to rotate and rewind the extension cable 203, the protective sleeve 207 located on the left side of the connector 204 will make prior contact with the right side of the outer casing 1. At this time, the connector 204, which continues to be pulled by the extension cable 203, will push the extension plate 205 to move into the protective sleeve 207, compressing the buffer spring 206 in the protective sleeve 207. The deformation of the buffer spring 206 buffers the tension on the connector 204, preventing the connector 204 from directly hitting the right side of the outer casing 1, causing damage to the connector 1 or causing it to fall off from the right side of the extension cable 203. The protection effect of the connector 204 is good.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
