Description
Technical field
The present invention relates to a kind of locking strip, specifically, relate to a kind of novel reed locking strip.
Background technique
Along with the development of science and technology, miniaturization, integrated and modularization are more and more tended in present military hardware design.The problem that first military hardware solves is exactly vibration problems.How to ensure between module and mainboard be connected to high-speed impact when do not lose efficacy, be exactly always connector assembly make great efforts direction.Locking strip, as the appearance of the structural member of raising board shock strength, alleviates connector assembly research and development difficulty to a great extent.So the operation environment of locking strip is more and more, from tank armor car to various boats and ships, to civilian and military aircraft, to space equipment.
The integrated of height also requires that present equipment safeguards facility as much as possible, so carrying out now " Second Echelon Maintenance " this military equipment in the world to safeguard theory always.Time this maintenance theory just requires to be equipped in and battlefield carries out safeguarding replacing, reduce the intractability of technician as much as possible and shorten the operating time.And in present military equipment, a lot of equipment all can only use hand-operated tools, and guarantee can not have misoperation.So how to accelerate the device security changing now speed and replacing, it is also present developing direction.
Existing locking strip structure as depicted in figs. 1 and 2, front wedge, wedge and back wedge is run through successively by stay bolt, and fix with nut, when being made spiral shell head and nut Distance Shortened by rotation stay bolt, correspondingly relative position is changed by inclined-plane between voussoir and wedge, the horizontal width of its entirety is increased, just can realize clamping locking.But this structure is found to have many problems in actual applications, first area of contact is too small, heavier plate can not be clamped, because existing locking strip and locking slot and plate surface of contact are the sides at tapered ramp two ends, wherein voussoir volume is all relatively little, and corresponding contact side is also less; It two is just do locating face with tapered ramp between existing voussoir and wedge, and when bolt is in loosening state, voussoir and wedge are all easy to relative to screws, are just easy to cause the locating face between voussoir and wedge not mate, and cannot normally lock; It three is annexations unstable between each parts of existing locking strip, when relaxation state, each component models is easy to drop, if parts drop and are easy to cause its components and parts Damage by Short Circuit on pcb board when the dismounting of practical application, so also limit existing locking strip structure can only adopt hand-operated tools and be difficult to adopt electronic dismantling device fast, to this, also someone expects that increasing Anti-fall nut in stay bolt end realizes electric operating, but this can increase again the entire length of locking strip and unnecessary assembly and causes using loaded down with trivial details and inconvenient; Its four be when with Vertical direction insert locking strip time, owing to there is no mutual tractive force between each voussoir by locating face restriction, Action of Gravity Field can make the activity of all voussoirs not meet user demand to its limit position, even sometimes also can snap into cabinet mural margin, have a strong impact on efficiency of assembling; It five is when locking strip is used to require the environment of high conduction performance to meet the designing requirement of electromagnetic shielding, due to the defect of the structural design of existing locking strip, its electric conductivity is very poor, even if adopt high conductivity material to make, the restriction of structure also cannot improve its electric conductivity significantly, and high conductivity material can not meet the processing request of existing locking strip structure preferably, the problems such as material and processing cost raise, difficulty of processing becomes large, structural strength reduction can be caused.
Summary of the invention
