Description

Technical Field

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

[0002] like Figure 8 The diagram shows a known USB connector, including a Type-C male connector with a metal housing 11 and a terminal assembly (not shown) fixed within the metal housing 11. It also includes a cable 13 connected to the rear end of the terminal assembly, and a USB connector adhesive 10 that integrally encapsulates the rear end of the metal housing 10 and the front end of the cable 13. Its purpose is to seal and waterproof, preventing dust, moisture, and other foreign matter from entering by filling the interface gaps, while providing physical protection and shock resistance. Specifically, the USB connector adhesive 10 encapsulates the various electronic components at the connection point between the Type-C male connector and the cable 13, enabling a combined connection between the Type-C male connector and the cable 13. The USB connector adhesive 10 and the metal housing 11 of the Type-C male connector cooperate to form a stable support structure, reducing the impact of external impacts and vibrations on the internal circuitry.

[0003] However, during daily use, the USB connector body 10 is a plastic part that is injection molded as a whole with the Type-C male connector and the cable as inserts. When the USB connector is frequently plugged and unplugged or used roughly, it may crack or break. After long-term use, it may wear and deform, resulting in poor contact or difficulty in plugging and unplugging. Therefore, a USB connector with internal potting 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] The internally potted USB connector includes a Type-C male connector with a metal shell and a terminal assembly fixed inside the metal shell. The cable connected to the rear end of the terminal assembly also includes a metal shielding shell that integrally encapsulates the rear end of the metal shell and the front end of the cable. The metal shielding shell has a cavity formed inside for placing the rear end of the metal shell and the front end of the cable. The cavity contains a glue that integrally encapsulates the rear end of the metal shell and the front end of the cable. The glue is integrally injection molded into the metal shielding shell with the Type-C male connector and the cable as inserts, so that the metal shielding shell provides further encapsulation and limitation when encapsulating and combining the Type-C male connector and the cable.

[0006] Preferably, the metal outer shell of the Type-C male connector has an outwardly protruding limiting member formed in a section located inside the metal shielding shell, the limiting member being used to engage with the shell surface of the metal shielding shell.

[0007] Preferably, the terminal assembly of the Type-C male connector includes a circuit board that is electrically connected to the cable, and the circuit board is located inside a metal shielding shell, and is encapsulated and confined inside the cavity by an adhesive.

[0008] Preferably, the colloid is further formed with a rubber ring that is integrally encapsulated with the cable, and the rubber ring is located at one end outside the metal shielding shell, and the rubber ring is used to connect with the colloid.

[0009] Preferably, the metal shielding shell has an inwardly curved limiting edge formed at one end of the metal outer shell located at the rear end of the Type-C male connector, and the limiting edge is used to engage with the shell surface of the metal outer shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the USB connector uses a metal shielding shell to encapsulate the rear end of the metal shell of the Type-C male connector and the front end of the cable in one piece. The interior is also filled with a colloid, which further confines the rear end of the metal shell of the Type-C male connector and the front end of the cable within the metal shielding shell, and at the same time increases the sealing performance between the metal shielding shell and the rear end of the metal shell of the Type-C male connector and the front end of the cable. In addition, the hardness and toughness of the metal shielding shell are much higher than those of the colloid shielding shell, which can withstand higher intensity external impact, squeezing or bending, and reduce interface damage caused by improper insertion or dropping.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-8 In this embodiment of the present invention, the internally potted USB connector includes a Type-C male connector 2, which has a metal shell and a terminal assembly fixed inside the metal shell. The cable 4 connected to the rear end of the terminal assembly also includes a metal shielding shell 1 that integrally encapsulates the rear end of the metal shell and the front end of the cable 4. A cavity 8 is formed inside the metal shielding shell 1 for placing the rear end of the metal shell and the front end of the cable 4. An adhesive 5 that integrally encapsulates the rear end of the metal shell and the front end of the cable is disposed inside the cavity 8. The adhesive 5 is integrally injection molded into the metal shielding shell 1 with the Type-C male connector 2 and the cable 4 as inserts, so that the metal shielding shell 1 provides further encapsulation and limitation when encapsulating and combining the Type-C male connector 2 and the cable 4.

[0024] The metal shell of the Type-C male connector 2 has an outwardly protruding limiting member 7 formed in a section inside the metal shielding shell 1. The limiting member 7 is used to engage with the shell surface of the metal shielding shell 1, so that the metal shell of the Type-C male connector 2 is limited relative to the metal shielding shell 1 in the length direction of the cable 4.

[0025] The terminal assembly of the Type-C male connector 2 includes a circuit board 6 that is electrically connected to the cable 4. The circuit board 6 is located inside the metal shielding shell 1, and the colloid 5 encapsulates it and confines it inside the cavity 8, making it less likely for the circuit board 6 to shift.

[0026] The colloid 5 is also formed with a rubber ring 3 that is integrally encapsulated with the cable 4. The rubber ring 3 is located at one end outside the metal shielding shell 1. The rubber ring 3 is used to connect with the colloid 5, so that the cable 4 is limited relative to the metal shielding shell 1 in the length direction of the Type-C male connector 2.

[0027] The metal shielding shell 1 has an inwardly curved limiting edge 9 formed at one end of the metal shell at the rear end of the Type-C male connector 2. The limiting edge 9 is used to engage with the shell surface of the metal shell, so that the metal shell of the Type-C male connector 2 is limited relative to the metal shielding shell 1 in the length direction of the cable 4.

[0028] 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.
