Description

Novel LRM module encapsulation

Technical Field

The utility model relates to a LRM module encapsulation technical field specifically is a novel LRM module encapsulation.

Background

In the 60S of the 20 th century, the U.S. naval began to study modularity with respect to Electronic equipment for ships and submarines, and issued MIL-M-28787D, the "general Standard Electronic module specification", in tandem with MIL-S1D-1389D, the "Standard Electronic module design requirement", and MIL-STD-1378E, the "Standard Electronic module use requirement", and defined an LRM module package of code SEM (Standard Electronic Modules). As shown in fig. 1. Because the standard release of the SEM module is early and the use range is wide, the SEM module is not only adopted by ground and offshore electronic equipment, but also widely used in the field of aviation. SEM-E module sizes were as follows:

(1) Length: 169.67mm (6.68 inches);

(2) Width: 19.35mm (5.88 inches).

The module can have 5 different thicknesses as desired, with a standard thickness of 9.652mm (o.38 inches). The connector pin count may be 100, 150, 200, 250 depending on the thickness. The SEM-E module standard is widely applied to avionics equipment.

Early europe was primarily concerned with the use of the united states related military standards. In order to establish an electronic equipment standard system, the united standard avionics system committee ASAAC is established autonomously in various countries (mainly English, french and Germany), and the ASAAC module standard is established. Fig. 2 is a schematic external view of an ASAAC module. The ASAAC module size is compatible with Eurocard (Eurocard) standards as follows:

(1) Width: 20mm, and if desired, up to 30mm or 40mm:

(2) Height: 160mm;

(3) Length: 233.45mm.

The ASAAC module specifies the type of connector, including fiber optic receptacle, electrical signal receptacle, and power receptacle. Compared with a pin socket used by SEM-E, the socket of the ASAAC module is more advanced and has higher reliability.

The VITA48 standard is a recent upgrade to the VME bus standard. The VME bus is applied in large scale in professional fields requiring high reliability, such as military, aerospace, automation, etc., but with the great improvement of the performance of electronic devices, the bandwidth and the cooling capacity of the VME bus are difficult to meet the requirements. In order to achieve greater bandwidth and greater cooling capacity, the VITA (i.e., VME International trade Association) organization began to set forth the VITA48 standard. The VITA48 Standard is generally known as "mechanical Specifications for reinforced Reinforcement design"

The external dimensions of the VITA48 standard module are still compatible with the traditional VME module, and there are three main types, namely:

(1) 3U multiplied by 100, the size is 100mm multiplied by 160mm, the 3U plate is called as 3U plate for short, and the single height template is also called as single height template in China;

(2) 6U is multiplied by 160, the size is 160mm is multiplied by 233mm, the plate is called 6U plate for short, and the plate is also called double-height template in China;

(3) 9U 400, dimensions 366mm 400mm, referred to as 9U plate for short.

The VITA48 air cooling module and the VITA48 cold conducting module are shown in FIGS. 3 and 4, respectively.
