Problems solved by technology

[0005] At present, LRM connectors are generally terminated on printed boards by means of bent-in tail-end termination technology, but as the arrangement density and number of cores increase, it becomes more difficult or even impossible to bend the tail-end

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0030] As shown in Figure 1: the LRM connector plug of the present invention is mainly composed of shell A1, shell B2, locking screw 3, guide pin 4, coding piece 5 and low-frequency high-density surface mount base assembly 6; low-frequency high-density The flange of the surface mount base assembly 6 is engaged with the groove in the shell A1 and the shell A2, and the shell A1 and the shell A2 are fixed together with the screws 3, so that the connector is fixed; the guide pin 5 is screwed into the In the corresponding threaded hole of the housing A1, the coding piece 4 is interference-fitted in the groove of the housing B to prevent mis-insertion.

[0031] Such as figure 2 Shown: the LRM connector plug low-frequency high-density surface mount base assembly of the present invention consists of a base 6.1, a shielding cover 6.2, a fixing bar 6.3, a pin assembly A6.4, a...

Abstract

The invention provides an LRM (Line replaceable module) low-frequency high-density surface mount connector plug, which comprises a shell A, a shell B, a lock screw, a guide pin, a coding piece and a low-frequency high-density surface mount base assembly, wherein the flange of the low-frequency high-density base assembly is clamped by the grooves of the shell A and shell B; the shell A and the shell B are fixed together by screws so as to fix the connector; the guide pin is locked in a corresponding screwed holes on the shells in a thread way, and the coding piece is in the interference fit with the grooves of the shells. The connector plug has simple structure, spectrum arrangement density and core quantity can be increased by changing the end connection mode of ends. The invention provides a 2-row circular arc surface-mount structure for a connector, which is formed by bending the tail ends of 8 rows of contact elements.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an LRM low-frequency and high-density surface mount electrical connector plug. Background technique [0002] With the emergence of very high-speed integrated circuits (VHSIC), very large-scale integrated circuits (VLSI), and surface mount technology (SMT), the perfection of software programming languages ​​and data multiplexing buses has reduced the past few printed circuit boards into one Printed circuit boards are a reality. Therefore, the repeated parts of each computer on the aircraft electronic equipment are extracted and made into various independent general-purpose modules: such as power supply, data and signal processing, output / input, and memory. These modules are called first-level electrical modules. , thus greatly reducing the size and weight of the entire computer system. In addition, the various tasks of the original computers are decomposed into many basic functional mo...
