Description

Technical Field

[0001] The utility model relates to the technology of the field of electrical connectors, and in particular to an integrated terminal module for a 6-pin Type-C connector. Background Art

[0002] Type-C is a USB interface standard with a smaller size than Type-A and Type-B. It can be used for both PCs (master devices) and external devices (slave devices, such as mobile phones). Type-C has 4 pairs of TX / RX breakouts, 2 pairs of USBD+ / D-, a pair of SBU, 2 CCs, as well as 4 VBUS and 4 ground lines. On October 4, 2022, local time, the European Parliament passed a bill with an overwhelming majority. The bill stipulates that from the end of 2024, all new portable smart devices must use Type-C connectors; from 2026, Type-C connectors will also become the standard interface for laptop chargers. On October 25, 2022, Apple confirmed that it would comply with EU requirements and that all smartphones would use Type-C connectors from 2024.

[0003] The terminal block is a key component of the Type-C connector. Its main structure includes an insulator body, a terminal block, and a hook. The terminal block typically consists of two detection terminals, two power terminals, and two ground terminals. These terminals are connected to the same strip only at their rear ends. The terminal block and hook are molded separately and then placed into the mold to form the insulator body. This terminal block structure is unstable, resulting in uncertainty about the proper positioning of the individual terminals, affecting molding quality. Furthermore, the large number of components increases the difficulty of product manufacturing. Therefore, it is necessary to develop a solution to address these issues. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide an integrated terminal module for a 6-pin Type-C connector, which can effectively solve the problems of poor molding quality and difficulty in manufacturing the terminal module of the existing Type-C connector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An integrated terminal module for a 6-pin Type-C connector includes an insulating body and a terminal assembly. The insulating body includes a base and a tongue extending forward from the base. The terminal assembly is fixed to the insulating body by insert molding. The terminal assembly is formed from a metal sheet by a single stamping and bending process. The terminal assembly comprises a material strip, two detection terminals, two power terminals, and two ground terminals.

[0007] The two detection terminals are arranged on the left and right sides, and each detection terminal includes a first contact portion, a first fixing portion, and a first welding portion that are integrally formed and connected in sequence.

[0008] The two power terminals are arranged on the left and right, and are respectively located outside the two detection terminals. Each power terminal includes a second contact portion, a second fixing portion, and a second welding portion that are integrally connected in sequence. The second contact portions of the two power terminals are exposed from the upper and lower surfaces of the tongue plate, respectively. A first connecting rod is integrally connected between the front ends of the second contact portions of the two power terminals. The first connecting rod is embedded in the front end of the tongue plate. The second fixing portions of the two power terminals are embedded in the insulating body. The second welding portions of the two power terminals extend rearwardly out of the base and are integrally connected to the material strip.

[0009] The two grounding terminals are arranged on the left and right, and the two grounding terminals are respectively located on the outside of the two power terminals. Each grounding terminal includes a third contact portion, a third fixing portion and a third welding portion that are integrally connected in sequence. The third contact portions of the two grounding terminals are respectively exposed from the upper and lower surfaces of the tongue plate. A second connecting rod is integrally connected between the front ends of the third contact portions of the two grounding terminals. The second connecting rod is buried inside the front end of the tongue plate. Both ends of the second connecting rod have hook portions extending outward as a whole, and the two hook portions are respectively exposed from the left and right side surfaces of the front end of the tongue plate. The third fixing portions of the two grounding terminals are both buried in the insulating body, and the third welding portions of the two grounding terminals are both extended backward out of the base and are integrally connected with the material strip.

[0010] As a preferred solution, the first connecting rod and the second connecting rod both extend horizontally to the left and right, the second connecting rod is located in front of the first connecting rod, and the second connecting rod and the first connecting rod are arranged parallel to each other in a spaced manner.

[0011] As a preferred solution, two limiting grooves arranged left and right are provided on the top front side and the bottom front side of the base.

[0013] As a preferred solution, the top of the base is provided with two positioning protrusions arranged on the left and right, and the two positioning protrusions are respectively located on the sides of the two buckle grooves.

[0014] As a preferred solution, a plurality of pores are formed through the upper and lower surfaces of the tongue plate. The pores can reduce the material used for the insulating body and also reduce the impedance of each terminal, making it easier for high frequencies to pass through.

[0015] As a preferred solution, the outer surfaces of the first fixing part, the second fixing part and the third fixing part are all concave-convex frosted surfaces, which are combined with the insulating body to make the terminal group and the insulating body more firmly and reliably combined.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0017] By integrally forming a first connecting rod between the front ends of the second contact parts of the two power terminals and integrally forming a second connecting rod between the front ends of the third contact parts of the two grounding terminals, the overall structure of the terminal group is more stable. When forming the insulating body, the correct positioning of each terminal can be well guaranteed, and the molding quality is improved.

The second connecting rod 244 and the first connecting rod 234 are arranged parallel and spaced apart from each other, thereby ensuring a stable overall structure. Furthermore, the outer surfaces of the first fixing portion 222, the second fixing portion 232, and the third fixing portion 242 each have a concave-convex frosted surface 201. This concave-convex frosted surface 201 is integrated with the insulating body 10 to ensure a more secure and reliable connection between the terminal assembly 20 and the insulating body 10.

[0045] The production process of this embodiment is described in detail as follows:

[0046] During production, a metal sheet is first placed in a stamping die, where it is stamped and bent in a single pass to form the terminal assembly 20.
