[0002] Type-C connectors are a modern USB connector standard that supports both power and data transfer. As consumers increasingly demand faster signal transmission and charging speeds for electronic products, Type-C connectors are constantly being improved in terms of connectivity. Consequently, the number of internal terminals in Type-C connectors is increasing, and the internal structures, including terminals and cores, are becoming more complex. This leads to more complicated assembly processes for these internal structures, resulting in a rising production cost for Type-C connectors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an integrated Type-C connector core, which is easy to process, reduces the defect rate of the finished connector core, eliminates the corresponding assembly process, reduces assembly costs, and improves the production efficiency of Type-C connectors.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An integrated Type-C connector core includes:

[0006] Several terminals, each terminal including a gold finger at the head and a pin at the tail, the pins being Z-shaped;

[0007] The middle clip includes a connecting piece at the head and a tail piece at the tail. The connecting piece is arranged parallel to the bottom of several gold fingers and has several positioning holes spaced apart on it. The tail piece is Z-shaped and integrally disposed on both sides of the tail end of the connecting piece, and the tail piece is located on both sides of several pins.

[0008] The first colloid is disposed between several gold fingers and connecting pieces. After cooling and forming, it is used to fix several gold fingers and connecting pieces. Several positioning protrusions are formed on the lower surface of the first colloid to match the positioning opening.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] like Figures 1-4 As shown, the integrated Type-C connector core includes several terminals 1, a middle clip 2, a first adhesive 3, and a second adhesive 4.

[0024] Each terminal 1 includes a gold finger 11 at the head and a pin 12 at the tail, the pin 12 being Z-shaped; the middle clip 2 includes a connecting piece 21 at the head and a tail piece 22 at the tail, the connecting piece 21 being parallel to the gold fingers 11 below, and the connecting piece 21 having a plurality of positioning holes 211 spaced apart, the tail piece 22 being Z-shaped and integrally disposed on both sides of the tail end of the connecting piece 21, and the tail piece 22 being located on both sides of the pins 12 and at the same height as the pins 12; the first colloid 3 is disposed between the gold fingers 11 and the connecting piece 21, and after cooling and forming, it is used to fix the gold fingers 11 and the connecting piece 21, the lower surface of the first colloid 3 having a plurality of positioning protrusions 31 adapted to the positioning holes 211; the second colloid 4 is disposed between the pins 12 and the tail piece 22, and after cooling and forming, it is used to fix the pins 12 and the tail piece 22.

[0025] The present invention comprises several terminals 1 and a middle clip 2, which are stamped from thin metal strips. The connecting piece 21 of the middle clip 2 and the gold fingers 11 of the terminal 1 are stacked and placed in a corresponding plastic mold to be integrally formed with the first colloid 3 and the second colloid 4 to form the connector core. The first colloid 3 is used to fix several gold fingers 11 and connecting pieces 21 after cooling and forming. The second colloid 4 is used to fix several pins 12 and tail pieces 22 after cooling and forming. The working parts of the gold fingers 11 and connecting pieces 21 are exposed outside the first colloid 3, and the working parts of the pins 12 and tail pieces 22 are exposed outside the second colloid 4 to realize the corresponding connection and conduction functions. This integrally formed core structure is easy to process, reduces the defect rate of the connector core, eliminates the corresponding assembly process, reduces assembly costs, and improves the production efficiency of Type-C connectors.

[0026] In this embodiment, the Type-C connector core also includes a core 6. The core 6 includes, from front to back, an input section 61, a positioning section 62, and an output section 63. The input section 61 is provided with a connecting shell 611. The upper surface of the first colloid 3 is provided with a plurality of first reinforcing protrusions 33, which are integrally formed with the input section 61. The upper surface of the second colloid 4 is provided with a plurality of second reinforcing protrusions 41, which are integrally formed with the output section 63. After the injection molding of the first colloid 3 and the second colloid 4 is completed, high-temperature molten plastic is injected into the connector core to form the core 6, so that the terminal 1 and the middle clip 2 are embedded in the core 6. During this process, the first reinforcing protrusions 33 are integrally formed with the input section 61, and the second reinforcing protrusions 41 are integrally formed with the output section 63, thereby enhancing the connection stability of the first colloid 3, the second colloid 4, and the core 6, and avoiding plastic detachment, loosening, etc.

[0027] In this embodiment, an insertion portion 5 is provided between the tail piece 22 and the connecting piece 21; slots 32 adapted to the insertion portion 5 are formed on both sides of the rear part of the first adhesive 3. The insertion portion 5 is connected to the slots 32, which can limit the middle clamp piece 2 and further improve the connection between the middle clamp piece 2 and the first adhesive 3.

[0028] The front end of the connector 21 has protrusions 212 on both sides of several gold fingers 11. When the Type-C connector is inserted into the male connector, the protrusions 212 engage and contact with the male connector, which can reduce the wear of the male connector on the core 6.

[0029] In this embodiment, each gold finger 11 has a downwardly bent portion 111 at its front end. The bent portion 111 is embedded in the first colloid 3, which enhances the connection between the gold finger 11 and the first colloid 3; when the Type-C connector is inserted into the male connector, the gold finger 11 can make stable contact with the insertion end of the male connector, which has good stability.

[0030] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
