[0020] Please see Figures 1 to 5 An integrated connector according to an embodiment of the present invention includes a connector housing (400), a first pin assembly, and a second pin assembly. The first pin assembly consists of a first insulator (110) and first pins (120) arranged in a matrix, with the first insulator (110) housed inside a cylindrical shield (300). The second pin assembly consists of a second insulator (210) and second pins (220) arranged in a circular pattern, with the shield (300) sleeved inside the second insulator (210). An annular groove (410) is provided on the inner side of the connector housing (400), which matches the flange (211) on the outer periphery of the second insulator (210). Physical isolation of signal and power transmission functions is achieved through the matrix arrangement of the first pins (120) and the circular arrangement of the second pins (220). The cylindrical design of the shielding component (300) both encloses the first insulator (110) and nests the second insulator (210), forming a double-layer spatial layout, thereby reducing the complexity of internal wiring. The flange (211) of the second insulator (210) engages with the annular slot (410) of the housing (400) to ensure assembly stability. In actual assembly, the first pin (120) is arranged in a 5×5 matrix in the first insulator (110) for transmitting high-speed signals; the second pin (220) has 16 pins evenly distributed along the outer circumference of the second insulator (210) for high-current power supply. When the shielding component (300) is fitted onto the second insulator (210), its inner wall is clearance-fitted with the outer diameter of the second insulator (210) to form an electromagnetic shielding cavity. After the flange (211) is inserted into the annular slot (410), circumferential fixation is achieved by rotating the second insulator (210).

[0021] Please see Figures 1 to 5In another embodiment, the shielding member (300) has a first annular retaining edge (310) at its first end, and a second annular retaining edge (111) is formed on the outer edge of the first insulator (110) that axially aligns with the first annular retaining edge (310). The axial interlocking of the first annular retaining edge (310) and the second annular retaining edge (111) restricts the axial displacement of the first insulator (110), while simultaneously creating physical isolation between the first pin (120) and the inner wall of the shielding member (300), reducing signal interference. The retaining edge structure also simplifies the assembly process; the first insulator (110) only needs to be pushed into the shielding member (300) until the retaining edge is in contact to complete the pre-positioning. The outer diameter of the first insulator (110) has a second annular retaining edge (111) protruding outwards, the outer diameter of which is equal to the inner diameter of the shielding member (300). During installation, after the first insulator (110) is pushed into the shield (300), the end face of the second annular stop (111) contacts the first annular stop (310) at the beginning of the shield (300). At this time, the position of the first pin (120) has been precisely defined and no additional adjustment is required.

[0022] Please see Figures 1 to 5 In another embodiment, a threaded retainer (500) is also included, the outer periphery of which is provided with an external thread (510) that mates with the internal thread (320) at the tail end of the shield (300). When screwed in, the front thrust surface (520) of the threaded retainer (500) contacts the rear end face of the first insulator (110). The axial clamping force of the first insulator (110) is adjusted by the threaded retainer (500). The engagement of the external thread (510) and the internal thread (320) allows for precise adjustment of the screw-in depth of the retainer (500), thereby compensating for manufacturing tolerances and ensuring reliable contact between the first pin (120) and the external interface. The planar design of the front thrust surface (520) avoids local stress concentration, and the first insulator (110) can be directly removed after disassembling the threaded retainer (500). During assembly, tighten the limiting member (500) until its front thrust surface (520) makes slight contact with the rear end of the first insulator (110) (in a non-overpressure state). At this time, the shield (300), the first insulator (110) and the threaded limiting member (500) form a rigid connection.

[0023] Please see Figures 1 to 5In another embodiment, a third annular flange (330) is provided at the center of the outer surface of the shield (300), forming a radial limiting fit with a fourth annular flange (212) provided on the inner circumference of the second insulator (210). The radial engagement of the third annular flange (330) and the fourth annular flange (212) restricts radial misalignment between the second insulator (210) and the shield (300), improving vibration resistance. The third annular flange (330) also serves as a structural reinforcing rib of the shield (300), preventing the cylindrical shield (300) from deformation under pressure. The third annular flange (330) is machined on the outer surface of the shield (300), with its outer diameter slightly larger than the inner diameter of the second insulator (210). When assembling the second insulator (210), slight elastic deformation causes the fourth annular flange (212) to pass over the third annular flange (330), forming a radial limiting fit and preventing relative displacement between the two under vibration.

[0024] Please see Figures 1 to 5 In another embodiment, the central angle of the annular slot (410) is 85-95 degrees to achieve the anti-misinstallation design of the second insulator (210).

[0025] Please see Figures 1 to 5 In another embodiment, the shielding element (300) is composed of a copper alloy substrate and a nickel-plated layer with a thickness of 3-5 μm. The copper alloy substrate provides high conductivity and structural strength, while the nickel plating layer prevents oxidation and reduces contact resistance. The 3-5 μm thick plating layer ensures shielding effectiveness while avoiding excessive thickness that could lead to increased brittleness or higher costs.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
