Abstract
The invention relates to an impact resistant method for installing a relay. The method comprises the following steps of: placing the relay to be fixedly installed into a glue-pouring type cavity; pouring a hardenable insulated filler into gaps between the relay and the glue-pouring type cavity; and after curing the insulated filler, fixing the relay together with the glue-pouring type cavity to a complete machine base plate by using fastening bolts. By making use of the buffer action of the insulated filler, the impact resistant method for installing the relay reduces an impact force to the relay, and greatly improves the impact resistance of the relay under the condition of not changing the inner structure of the relay, so that the impact resistance of the whole electronic control assembly is improved. The method can be used for installing various relays.
Description
One, technical field
The present invention relates to the Electronic Control Unit technical field, relate in particular to a kind of method for installing relay with impact resistance.
Two, background technology
Along with the develop rapidly of Aeronautics and Astronautics system, increasing complete machine model has proposed the HI high impact index request.Especially at sea in the machine system, it impacts index request all between 3000g～5000g.This just requires Electronic Control Unit such as relay inside to have certain shock resistance.Conventional method for installing relay as shown in Figure 1, be directly relay 3 to be rigidly connected on the base plate by hold-down screw 4 and the combination that journal stirrup 5 is installed, the shortcoming that this mounting means exists is: resistance to shock is relatively poor, index all between 100g～200g, differs more than 20 times with the performance that requires, under high thump, can aggravate the inefficacy of relay, can not satisfy instructions for use,, also its shock resistance can not be improved more than 20 times even optimize the structure of electromagnetic relay inside.
Three, summary of the invention
The purpose of this invention is to provide a kind of method for installing relay, to improve the shock resistance of machine system repeat circuit with shock resistance.
The technical solution used in the present invention is:
Described mounting means is to treat that earlier hard-wired relay packs in the encapsulating die cavity, between relay and encapsulating die cavity space, pour into hardenable insulating packing, insulating packing is fixed to the related encapsulating die cavity of relay on the complete machine base plate with hold-down screw after solidifying.
The quantity of described encapsulating die cavity is corresponding with the quantity and the shape of relay with profile.
Described insulating packing is an elastomeric material.
Beneficial effect of the present invention:
(1) when relay is subjected to high thump, the elastic deformation of packing material can be played the cushioning effect of good separating vibration, makes the big high attenuation of impulsive force magnitude that is applied on the relay, thereby improves the impact resistance of whole Electronic Control Unit;
(2) operation is simple, at the difformity relay, the shape of encapsulating die cavity changed accordingly, can be widely used in the installation of various relays.
Four, description of drawings
Fig. 1 is the mounting means schematic diagram of prior art relay;
Fig. 2 is the front view of method for installing relay of the present invention;
Fig. 3 is the vertical view of Fig. 2.
Among the figure: 1-encapsulating die cavity, 2-insulation filling material, 3-relay, 4-hold-down screw, 5-install journal stirrup, 6-base plate.
Five, embodiment
Below in conjunction with accompanying drawing the present invention is described in further details:
Shown in Figure 3 as Fig. 2, the structural member of method for installing relay of the present invention comprises encapsulating die cavity 1, insulation filling material 2, relay 3, hold-down screw 4, journal stirrup 5 and base plate 6 are installed, at first according to the quantity and the shaped design corresponding relays encapsulating die cavity 1 of the determined relay 3 of Electronic Control Unit in the specific embodiments, secondly relay 3 is put into the suitable position of encapsulating die cavity 1, pour between relay 3 and the encapsulating die cavity 1 as insulating packing 2 with fluid silicone rubber, make it fully fill space between encapsulating die cavity 1 and the relay 3, fully fixing to guarantee relay 3, after treating the silicon rubber cold curing at last, relay encapsulating die cavity 1 is placed on the base plate 6, utilizes hold-down screw 4 that encapsulating die cavity 1 is fixed on the base plate 6 by journal stirrup 5 is installed.
Above-mentioned base plate 6 is other constituent parts of circuit board or complete machine.
After adopting such scheme to install, when running into high-strength impact, the silicon rubber of filling in the encapsulating die cavity 1 can produce the vibration that the elastic deformation shock isolation causes.By the cushioning effect of silicon rubber, reduced impulsive force to relay, improve relay and complete machine shock resistance thereof.
