Description

Technical Field

[0001] This utility model relates to an electrical connector, specifically an optoelectronic hybrid hermetic electrical connector for cable assemblies. Background Technology

[0002] In fields such as industrial control, aerospace, and underwater equipment, where airtightness and signal transmission integration are critical, existing optoelectronic hybrid connectors often use adhesive or mechanical snap-fit ​​methods to assemble the insulating components, housing, and end caps. This results in minute gaps, and sealing relies on sealing rings or sealant. Over long-term use, the seals are prone to aging and cracking, or assembly errors can lead to seal failure. Moisture and impurities can easily penetrate, causing pin corrosion, decreased insulation resistance, and even short-circuit failures. Summary of the Invention

[0003] This utility model provides a photoelectric hybrid airtight electrical connector for cable assemblies with a stable installation structure, controllable installation accuracy, and guaranteed quality and service life.

[0004] The technical solution adopted by this utility model is: a photoelectric hybrid airtight electrical connector for cable assemblies, including a plug and a cable connector, wherein the tail of the plug is connected to the cable via a cable for fixed connection, characterized in that: the plug includes a head shell, a positioning sleeve, a locking sleeve, multiple electrical signal pins and one or more optical signal pins, a central plate is integrally provided inside the head shell, front and rear insulating parts are respectively provided at the front and rear ends of the central plate, a front cover plate is provided at the front end of the front insulating plate, and a rear cover plate is provided at the rear end of the rear insulating plate, multiple electrical signal pins and one or more optical signal pins are connected from front to back through the front cover plate, the front insulating part, the central plate, the rear insulating part and the rear cover plate inside the head shell, the locking sleeve is externally threaded to the rear end of the head shell, the rear end step of the locking sleeve is pressed and sleeved on the rear end of the positioning sleeve or the outer wall step inside the locking sleeve, the front end of the positioning sleeve abuts against the rear cover plate, and the cable connector is connected to the rear end of the positioning sleeve.

[0005] The front and rear insulating components are integral glass sintered structures with the head shell.

[0006] The front and rear insulating components are integrally sintered into the front and rear end caps, respectively.

[0007] The cable connector consists of a locking seat and a locking cover. The locking seat is connected to the rear end of the positioning sleeve, and the locking cover, which is screwed onto the locking seat, is used to secure the cable.

[0008] The beneficial effects of this utility model are: 1. The central plate, with its integrated front and rear insulation components and head housing, utilizes a glass sintering structure. This eliminates assembly gaps between the insulation components and the head housing / end cap, significantly improving airtightness and effectively preventing the intrusion of moisture, dust, and other impurities, thus avoiding corrosion or short circuits in the internal pins. The integrated sintering structure reduces detachable connection points, resulting in high overall mechanical strength and resistance to structural damage from external impacts. The sintering process ensures the coaxiality and assembly precision of the pins, insulation components, and head housing, reducing signal transmission loss and significantly improving the stability of optical signal transmission. It also possesses high-temperature resistance and anti-aging properties, ensuring long-term stable sealing performance and suitability for long-term use in harsh environments.

[0009] 2. The threaded engagement between the locking sleeve and the positioning sleeve axially locks the internal components, preventing displacement under vibration and impact conditions, ensuring reliable pin contact and stable signal transmission. The integrated layout of electrical and optical signal pins enables synchronous transmission of electrical and optical signals, eliminating the need for separate electrical and optical connectors and simplifying cable assembly wiring and installation.

[0010] 3. The cable is fixed by screws on the locking seat and cover plate. No special tools are required for disassembly and assembly. The operation is simple, the cable is firmly fixed, and the cable has strong tensile strength. Attached Figure Description
