Description

Technical Field

[0001] This utility model relates to the field of external device connection interface technology, and in particular to USB connectors. Background Technology

[0002] like Figure 7 The diagram shows a known USB connector, including a Type-C male connector with a metal housing 7 and a terminal assembly (not shown) fixed within the metal housing 7. It also includes a cable 9 connected to the rear end of the terminal assembly, and a plastic mold 8 that integrally encapsulates the rear end of the metal housing 7 and the front end of the cable 9. The purpose of this mold is to seal and waterproof the connector, preventing dust, moisture, and other foreign matter from entering by filling the interface gaps, while also providing physical protection and shock resistance. Specifically, the plastic mold 8 encapsulates the various electronic components at the connection point between the Type-C male connector and the cable 9, allowing for a combined connection between the Type-C male connector and the cable 9. The plastic mold 8, together with the metal housing 7 of the Type-C male connector, forms a stable support structure, reducing the impact of external impacts and vibrations on the internal circuitry.

[0003] However, during daily use, the Type-C male connector is repeatedly plugged in and unplugged from its matching Type-C female connector, causing a pulling force between the metal shell 7 and the plastic mold 8 of the Type-C male connector. Since the surface of the metal shell 7 of the Type-C male connector is smooth and flat, and the connection between it and the plastic mold 8 is a surface-to-surface fit, the contact surface between the metal shell 7 and the plastic mold 8 separates during the pulling process. As a result, the Type-C male connector gradually loosens from the plastic mold 8 during plugging and unplugging until it completely detaches, leading to unstable signal transmission and frequent disconnections during use. Therefore, this USB connector solution is proposed. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] A USB connector includes a Type-C male connector, which has a metal shell and a terminal assembly fixed inside the metal shell; it also includes a cable connected to the rear end of the terminal assembly, and a plastic mold that integrally encapsulates the rear end of the metal shell and the front end of the cable; the plastic mold is integrally injection molded with the Type-C male connector and the cable as inserts, and the metal shell of the Type-C male connector has an outwardly protruding limiting member formed in a section located inside the plastic mold, the limiting member being used to interlock with the plastic body of the plastic mold, so that the metal shell of the Type-C male connector is limited relative to the plastic mold in the length direction of the cable.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7In this embodiment of the present invention, the USB connector includes a Type-C male connector, which has a metal shell 2 and a terminal assembly fixed inside the metal shell 2; it also includes a cable 4 connected to the rear end of the terminal assembly, and a plastic mold 1 that integrally encapsulates the rear end of the metal shell 2 and the front end of the cable 4; the plastic mold 1 is integrally injection molded with the Type-C male connector and the cable 4 as inserts, and the metal shell 2 of the Type-C male connector has an outwardly protruding limiting member 5 formed in a section located inside the plastic mold 1. The limiting member 5 is used to interlock with the plastic body of the plastic mold 1, so that the metal shell 2 of the Type-C male connector is limited relative to the plastic mold 1 in the length direction of the cable 4. Thus, when the USB connector is plugged in or unplugged, the interlocking and limiting between the limiting member 5 and the plastic mold 1 makes it difficult for the Type-C male connector to loosen and break off from one end of the plastic mold 1.

[0028] The limiting member 5 is a flange protruding outward from the metal shell 2 of the Type-C male connector. The outward protruding end face of the flange interlocks with the shell surface formed inside the mold 1. During the insertion and removal of the Type-C male connector and its corresponding Type-C female connector (not shown in the figure), a tensile force is generated between the Type-C male connector and the mold 1. During the tensile process, the adhesive between the Type-C male connector and the mold 1 will loosen. However, at the same time as the loosening, the Type-C male connector will move in position, causing the flange to move in position synchronously. Since the shell surface blocks the front end of the flange flange, the flange flange and the shell surface interlock with each other. After the Type-C male connector and the mold 1 loosen, the Type-C male connector is still located at one end of the mold 1, making it less likely for the Type-C male connector and the cable 4 to break.

[0029] The limiting member 5 is a protrusion formed on the upper and lower ends of the metal shell 2 of the Type-C male connector, and the upper and lower ends of the mold 1 are formed with protrusions that interlock with the protrusions. The rest of the inner surface of the mold 1 is in contact with the metal shell 2 of the Type-C male connector. During the insertion and removal of the Type-C male connector and its corresponding Type-C female connector (not shown in the figure), a pulling force is generated between the Type-C male connector and the mold 1. During the pulling process, the adhesive between the Type-C male connector and the mold 1 will loosen. However, at the same time as the loosening, the Type-C male connector will move, and the protrusion will move in the same direction. Since the shell surface is blocked at the front end of the flange flange, the protrusion and the protrusion interlock with each other. After the Type-C male connector and the mold 1 loosen, the Type-C male connector is still located at one end of the mold 1, so that the Type-C male connector and the cable 4 are not easily disconnected.

[0030] The limiting component 5 consists of several limiting blocks formed on the outside of the metal shell 2 of the Type-C male connector and protruding outwards. These limiting blocks are distributed around the outside of the metal shell 2 of the Type-C male connector, and are arranged in an interlocking manner. Furthermore, the limiting blocks interlock with the shell surface formed inside the mold 1. During the insertion and removal of the Type-C male connector from its mating Type-C female connector (not shown in the figure), a pulling force is generated between the Type-C male connector and the mold 1. During this pulling process, the adhesive between the Type-C male connector and the mold 1 may loosen. However, at the same time as the loosening, the Type-C male connector will move, causing the limiting blocks to move simultaneously. Because the shell surface is filled and trapped in the interlocking positions formed between the limiting blocks, the limiting blocks interlock with the shell surface. Even after the Type-C male connector loosens from the mold 1, it remains at one end of the mold 1, making it less likely for the Type-C male connector to break off from the cable 4.

[0031] The limiting member 5 is fixed to the metal shell 2 by spot welding or is set on the metal shell 2 by stamping. The limiting member 5 is located in the middle section outside the metal shell 3 or at the edge near one end of the cable 4.

[0032] The Type-C male connector has a circuit board 6 that is electrically connected to the cable 4 inside, and the circuit board 6 is located inside the mold 1, and the mold 1 wraps the circuit board 6. A data cable tail 3 is also provided at the connection between the cable 4 and the mold 1. The data cable tail 3 is integrally formed on the outside of the cable 4 or is sleeved on the outside of the cable 4. Thus, the data cable tail 3 can prevent the cable 4 from being bent and broken during use.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
