Description

A complex connector device for Tacon precision ranging shipboard airborne system

technical field

The present invention relates to a composite connector device.

Background technique

Tacom precision ranging shipboard airborne radio navigation equipment is an important part of a certain type of aircraft integrated avionics system, which can realize Tacan ground-to-air navigation, air-to-air ranging and landing/landing functions, and also has data link communication with the aircraft The function of device communication.

Due to the tolerance of the cable socket connected to Tacon’s precision ranging shipboard airborne radio navigation equipment, when the plug is screwed in and out during use, it is easy to make the connector rotate in the mounting hole, causing the socket to loosen, causing the socket and The plug is in poor contact, resulting in short-term or long-term data link communication equipment not being able to connect to the network normally. Therefore, it is urgent to improve the connectors between the Tacan sky control unit and the data link communication equipment.

Aiming at the situation of connector loosening, many researchers have proposed various design schemes, but the focus of their design is on the flange connector. However, the installation space of the fixed flange and the flange connector is relatively large, there is no space margin, which is not conducive to heat dissipation, and the direct reinforcement of the through-wall connector may cause loosening of the connector due to errors in the size of the installation hole and the installation method. .

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a two-piece through-the-wall connector. Two D-shaped holes are processed on the brass plate, and two JSMA-KYK sockets are welded on the brass plate. The two sockets It has a linkage effect and mutual restraint, which is equivalent to lengthening the resistance arm; and the socket is fixed by a flange, and there is no strict requirement on the machining accuracy of the connector mounting hole size of the Tiankong power unit shell, and the connector is firmly installed and not easy to loosen. The reliability of the entire connector is greatly improved, thereby increasing the network access rate of data link communication equipment.

The technical solution adopted by the present invention to solve the technical problem is: comprising a copper plate and two JSMA-KYK radio frequency coaxial connectors; the copper plate has two through holes; the JSMA-KYK radio frequency coaxial connector Pass through the through hole and connect with the copper plate through the flange; the axes of the two JSMA-KYK RF coaxial connectors are parallel.

The flange and the copper plate are connected by silver soldering.

Described copper plate adopts the brass plate of 1mm thickness.

The beneficial effect of the invention is: the through-wall installation method of combining the copper plate and two JSMA-KYK radio frequency coaxial connectors, adding a resistance arm, can provide more reliable connection performance. Among them, the installation of the two conjoined parts through the wall not only occupies a small area on the panel of the cabinet, but also has no strict requirements on the machining accuracy of the socket installation hole size of the Tiankong power supply unit housing, and is easy to install. In addition, the connector installation is very firm and not easy to loosen , can improve the reliability of the equipment. Through the combined use of multiple radio frequency coaxial connectors, the connectors of the improved Tacon precision ranging shipboard airborne radio navigation equipment and data link communication equipment, while not affecting the electrical performance of the equipment, compared with the original connector Reliability is greatly improved. In the composite connection method proposed by the present invention, the copper plate realizes the fixation of two JSMA-KYK radio frequency coaxial connectors, and the JSMA-KYK radio frequency coaxial connector plays the role of connecting two devices, and the installation method through the wall occupies a small area. A two-piece through-wall connector is formed. The present invention can not only be used for the connection between Tacom's precise range-finding shipboard airborne radio equipment and data link communication equipment, but also be applicable to equipment that needs to be connected locally in other systems.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

The purpose of the invention is to provide a reliable connector for the sky control unit and the data link communication system of the Tacan radio navigation equipment. The key point of the invention is to adopt the two-piece wall-mounted fixing method, and weld two JSMA-KYK sockets on the processed brass plate to form a composite Tacan precision ranging shipboard airborne radio equipment connector device. It is composed of a copper plate 2 and a radio frequency coaxial connector 3, and the radio frequency coaxial connector 3 includes two JSMA-KYK connectors. The JSMA-KYK connector is a radio frequency coaxial adapter from the inner jack contact to the jack nut of the jack contact. The inner conductor is beryllium bronze with nickel base and hard gold plating on the surface; the outer shell is brass and the surface is plated Nickel; Teflon as insulator. The copper plate 2 adopts a 1mm brass plate, and two D-shaped holes 4 with a size of 5.9mm/Φ6.30mm are processed on the surface (the size of the actual connector is 5.8mm/Φ6.20mm), wherein the size of the hole is 2×Φ6.30mm±0.1. The spacing is the same as that of the shell, and the two JSMA-KYK sockets are fixedly connected to the processed brass plate through the flange 1, which is equivalent to lengthening the resistance arm by 15mm. Silver welding is used between the copper plate and the flange, which can be heated evenly and reduce the lack of welding and missing solder joints. The present invention increases the resistance arm by means of a two-piece through-the-wall installation method with linkage effect, so as to achieve the purpose of enhancing the connectivity between devices.
