Compared with the existing technology comparatively, the beneficial effect that the present invention is provided with the intercom of waterproof construction is:
1, because whole intercom is provided with waterproof construction, metal electrode waterproof construction, antenna and turn button waterproof structure between face-piece and aluminum hull, PTT and function button waterproof construction, earphone interface waterproof construction, loud speaker waterproof construction, LED post and alarm key waterproof construction and battery compartment waterproof construction, each parts that intercom is contacted with water can reach the effect of waterproof, make whole intercom reach IPX7 level water protection standards;
2, the waterproof construction particularly between face-piece and aluminum hull comprises water proof ring and four screw water proof rings; and face-piece is also provided with a circle projection; so just can ensure that water proof ring is pressed between the projection of face-piece and a ring recess position of aluminum hull, aluminum hull and the fixing rear waterproof effect of face-piece are improved greatly; And there is no projection inside the face-piece of the best intercom of prior art waterproof effect, after assembling, face-piece sidewall is easily out of shape laterally under water proof ring transverse shear stress, causes water proof ring pressurized dynamics inconsistent, can not reach complete waterproof;
3, particularly metal electrode waterproof construction comprises both positive and negative polarity support and both positive and negative polarity silicagel pad, and two metal electrodes are injection-moulded in a formation one-piece parts in both positive and negative polarity support by employing, greatly increase their waterproof effect; And the best intercom both positive and negative polarity used support of prior art waterproof effect and metal electrode are two independent parts, their process and assemble form, and do not reach the requirement of waterproof at all;
4, particularly antenna and turn button waterproof structure comprise the potentiometer switch water proof ring be enclosed within respectively on described potentiometer switch, channel encoder and SMA antenna pedestal, channel encoder water proof ring and SMA antenna pedestal water proof ring; and potentiometer switch, channel encoder, SMA antenna pedestal are waterproof potentiometer switch, waterproof channel encoder and waterproof SMA antenna pedestal respectively; like this after their assemblings, waterproof effect also substantially increases; And prior art waterproof effect best intercom water proof ring design coordinate not in place; and potentiometer switch, channel encoder and SMA antenna pedestal itself is also non-watertight; easily from the position in three holes of their assemblings and they three, the part of itself penetrates into intercom inside to the water capacity, and affects the normal use of intercom;
5, particularly PTT and function button waterproof construction comprise stainless steel catch, and PTT silica gel push-button and function button are pressed on the madial wall of face-piece by this stainless steel catch, thus improve waterproof effect; And the best intercom of prior art waterproof effect does not have design and installation stainless steel catch, completely by PTT silica gel push-button and and the elastic force of function button self coordinates with face-piece, tight owing to coordinating, normal occur seeping water arrive the phenomenon of intercom inside;
6, earphone interface waterproof construction comprises receiver circuit board, 3M double faced adhesive tape and marine glue, and whole earphone interface reaches waterproof requirement to adopt this structure to ensure; And the best intercom of prior art waterproof effect uses holes earphone and MIC socket, with a silica gel or the closed with covers face-piece opening of other flexible glue material, waterproof effect is undesirable;
7, the loud speaker that particularly loud speaker waterproof construction adopts is water-proof loudspeaker, and after loud speaker assembles, has marine glue, also improve waterproof effect at one circle edge coated;
8, particularly LED post and alarm key waterproof construction comprise alarm key catch, and this alarm key catch can push down alarm key, makes it reach waterproof requirement; And after lamppost assembles, within it a circle edge coated has marine glue, also improves waterproof effect; And the best intercom of prior art waterproof effect does not have alarm key catch, the water capacity easily penetrates in intercom;
9, particularly battery compartment waterproof construction comprises battery waterproof circle, and this battery waterproof circle can ensure that cell cover forms an airtight cavity and reaches waterproof requirement after battery lower cover is together with ultrasonic fusing; And the best intercom of prior art waterproof effect does not have battery waterproof circle, cell cover and battery lower cover only carry out sealed cell cavity by ultrasonic welding, are difficult to reach waterproof requirement, and waterproof consistency is poor.
In sum, intercom of the present invention can reach IPX7 level water protection standards, though fall in rugged environment soak in water after get can also normal talking, solving prior art intercom can not thorough anti-water problem, can use in severe moist environment.
