Performance and product design of opto-electric hybrid connectors

Previously, high-voltage connectors, low-voltage connectors, and fiber optic connectors were installed separately in electronic equipment, but as high- and low-voltage and fiber-optic terminals increased, the space required for installation became larger and larger, and maintenance and maintenance became more difficult. . Modern and future wars require miniaturization, integration and modularization of military electronic equipment, and the requirements are getting higher and higher. Many components of foreign advanced weapon systems are integrated and modularized. Once there are problems, they can be used. The laptop is connected to the data detection system on the weapon and equipment for online detection. The damaged module can be replaced as soon as possible after the detection, so the maintenance and maintenance are particularly convenient, saving maintenance time and surviving the battlefield. In this context, many components of military electronic equipment have been integrated, and opto-electric hybrid connectors have emerged, effectively solving the installation space and maintenance problems.

The connector of this paper is mainly used for data connection of power supply, electric signal and optical signal in electronic countermeasure equipment. It can not only have low-voltage contacts and high-voltage contacts, but also optical contacts, which are fiber connectors, low-voltage connectors and An organic combination of high voltage connectors.

Product overall structural design

This connector belongs to the multi-core fast separation class. In order to prevent mis-insertion, the plug housing and the socket housing are designed with a five-key slot structure; the multi-core quick-disconnect type connector uses a staple and a spiral sleeve for quick connection and quick separation, and the five-key slot is used to complete the connector positioning and connection. The sleeve is connected to the socket connector and the corrugated spring locking mechanism maintains a constant interface pressure. In order to achieve the purpose of rapid separation, the plug housing is provided with a connecting sleeve, and the inner wall of the connecting sleeve is provided with three spiral-shaped bayonet spiral grooves of equal pitch, and a through hole is formed at the bottom of the bayonet slot. Observe the engagement of the connector; correspondingly, the surface of the socket housing is designed with three staples that can be screwed to the bottom of the spiral groove, and the connector can be locked after the plug is screwed into place.

Due to the metal casing and EMI design, the reliability is high, and the high and low altitudes have excellent withstand voltage performance. The length of the cable can be arbitrarily adjusted according to different needs, and the installation is on site, and the application is more flexible.

The plug connector includes a connector sleeve, a housing, a soft mounting plate, a pin assembly, a jack assembly, a fiber optic contact including a 1.25 mm standard connector, and corresponding wires. The material of the mounting plate is silicone rubber, which is molded by die; the socket and the pin meet the requirements of GJB1216, and the contact piece of No. 20 is used, which is made of tin bronze. The structure is slotted and two-piece, and the aging after closing is outside. Use stainless steel casing for protection. After the product is assembled, the tail is bonded and sealed with silicone rubber to ensure the voltage resistance of the product.

The receptacle connector includes a housing, a mounting plate, a pin assembly, a jack assembly, fiber optic contacts including a 1.25 mm standard connector, and corresponding wires. The material of the housing is the thermosetting material DAP, which is molded by a die. The design and structure of the insulating mounting plate have the correct cross section and corner radius so as not to be damaged, broken or broken during normal assembly and use. The insulating mounting plate is designed so that all contacts are securely held in the insulating mounting plate. The product is encapsulated with silicone rubber during assembly to block the air gap path and ensure the withstand voltage performance of the product.
