[0051] In some embodiments of the built-in resistor TYPE-C connector, the lower row of terminals 41 and the upper row of terminals 31 are snapped together and then molded to the plastic base 1. That is, by combining the upper row of terminal assemblies 3 and 4 and then molding them to the plastic base 1, the overall structural reliability is enhanced, making the terminals more securely fixed. In this embodiment, the upper row of terminals 31 and the lower row of terminals 41 are snapped together; this arrangement facilitates the assembly of the upper row of terminal assemblies 3 and 4.

[0052] As shown in Figures 6 and 10 to 12, in some embodiments of the built-in resistor TYPE-C connector of this embodiment, the upper row seat 31 has a snap hole 311 in the middle; the lower row seat 41 has a snap post 411 protruding from the middle; the snap post 411 passes into the snap hole 311. During assembly, the snap post 411 of the lower row seat 41 is inserted into the snap hole 311 of the upper row seat 31, thereby assembling the upper row terminal assembly 3 and the lower row terminal assembly 4 together, and then molding it with the plastic base 1; this facilitates the alignment of the upper and lower terminals.

[0053] As shown in Figures 10 and 12, in some embodiments of the built-in resistor TYPE-C connector of this embodiment, the upper row seat 31 has a plurality of first protrusions 312 on its upper surface; the lower row seat 41 has a plurality of second protrusions 412 on both its upper and lower surfaces; and the plastic base 1 has first holes corresponding to the first protrusions 312 and second holes corresponding to the second protrusions 412. This embodiment, by setting the first protrusions 312 and the first holes to cooperate, makes the connection between the upper row seat 31 and the plastic base 1 more secure, and by setting the second protrusions 412 and the second holes to cooperate, makes the connection between the lower row seat 41 and the plastic base 1 more secure.

[0054] As shown in Figures 1 to 5, in some embodiments of the built-in resistor TYPE-C connector of this embodiment, the tail end of the plastic base 1 is provided with a tail end connection part 12; preferably, the front end connection part 11, the tail end connection part 12 and the plastic base 1 are integrally formed, resulting in better structural strength.

[0055] The resistor element 5 is located on the tail end connection portion 12; after the tail ends of the two first lower terminals 42 are connected, a first welding portion exposed on the surface of the tail end connection portion 12 is provided on the tail end connection portion 12; after the tail ends of the two second lower terminals 43 are connected, a second welding portion exposed on the surface of the tail end connection portion 12 is provided on the tail end connection portion 12; after the tail ends of the first upper terminal 32 and the fourth lower terminal 45 are connected, a third welding portion exposed on the surface of the tail end connection portion 12 is provided on the tail end connection portion 12; in this embodiment, by providing the first welding portion, the second welding portion and the third welding portion, the terminals are welded to the connecting wires.

[0056] In some embodiments of the built-in resistor TYPE-C connector of this embodiment, one of the resistor elements 5 is connected between the tail end of the third lower terminal 44 and the tail end of the first lower terminal 42 by dispensing or screen printing, and the other resistor element 5 is connected between the tail end of the second upper terminal 33 and the tail end of the first lower terminal 42 by dispensing or screen printing. In this embodiment of the built-in resistor TYPE-C connector, the plastic base 1 has a connecting groove 122 corresponding to each resistor element 5, and the resistor element 5 is accommodated within the connecting groove 122. By providing the connecting groove, the resistor element 5 is formed within the connecting groove 122, so as to control the resistance accuracy.

[0057] To ensure the accuracy of the resistance value of the resistor element 5 within the confined space of the TYPE-C connector, dispensing or screen printing is employed. As shown in Figures 3 to 5, in some embodiments of the built-in resistor TYPE-C connector of this embodiment, the tail end connection portion 12 of the plastic base 1 is provided with a stepped portion 121. The stepped portion 121 is an upwardly protruding platform structure, and a connection groove 122 is provided for each resistor element 5. The resistor element 5 is accommodated within the connection groove 122. In this embodiment, by providing the connection groove 122, the resistor element 5 is positioned. Conductive adhesive or conductive ink is placed in the connection groove 122 by dispensing or screen printing, and the conductive adhesive or conductive ink forms the required resistor element 5 within the connection groove 122. Thus, the required resistor element 5 is manufactured within the confined space of the built-in resistor TYPE-C connector using conductive adhesive or conductive ink, eliminating the need for STM soldering, reducing manufacturing costs, and making the connection between the resistor element 5 and the terminal more secure and less prone to detachment.

[0058] To protect the resistive element 5 within the connection slot 122, in some embodiments of the built-in resistor TYPE-C connector of this embodiment, a receiving slot 123 is recessed in the stepped portion 121; the connection slot 122 is disposed at the bottom of the receiving slot 123; and a protective layer 6 is provided within the receiving slot 123. This embodiment provides protection for the resistive element 5 within the receiving slot 123 by setting the protective layer 6, resulting in a more reliable structure. Preferably, the protective layer 6 is a nano-coating.

[0059] Example 2: As shown in Figure 15, the difference between this example and Example 1 lies in the arrangement of the resistor element 5. In this example, one resistor element 5 is connected between the tail end of the third lower terminal 44 and the tail end of the first lower terminal 42 by welding, and the other resistor element 5 is connected between the tail end of the second upper terminal 33 and the tail end of the first lower terminal 42 by welding. The remaining structure is the same as in Example 1, and will not be described again here. The resistor element 5 adopts the STM surface mount welding method, which occupies little space. To facilitate the welding operation of the resistor element 5, the step portion 121 is a downwardly recessed planar structure.

[0060] The built-in resistor TYPE-C connectors of Embodiment 1 and Embodiment 2 can be manufactured by the following steps: First, the first upper terminal 32 and the second upper terminal 33 are molded with the upper row base 31 to obtain the upper row terminal assembly 3; then, the first lower terminal 42, the second lower terminal 43, the third lower terminal 44 and the fourth lower terminal 45 are molded with the lower row base 41 to obtain the lower row terminal assembly 4.

[0061] The obtained upper row terminal assembly 3 and lower row terminal assembly 4 are combined and assembled to obtain a terminal group; the obtained terminal group is then molded with the plastic base 1.

[0062] Then, the resistor element 5 is electrically connected between the third lower terminal 44 and the first lower terminal 42, and between the second upper terminal 33 and the first lower terminal 42, respectively; the metal shell 2 is fitted onto the plastic base 1; thus, a built-in resistor TYPE-C connector is obtained.

[0063] In this embodiment, the upper terminal assembly 3 and the lower terminal assembly 4 are assembled by molding them in one step, and then molded with the plastic base 1 in a second step. The overall structure is more compact, more reliable and stronger, and the manufacturing cost is low.

[0064] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
