Embodiment
Hereinafter will come to describe more all sidedly embodiments of the invention with reference to the accompanying drawing that the embodiment of the invention is shown.Yet, the present invention can implement with multiple different form, and should not be interpreted as being limited to embodiment described herein, and is opposite, provide these embodiment to make the disclosure become thorough and complete, and can fully scope of the present invention be conveyed to those skilled in the art.In the text, same mark is represented same element.
Specific embodiment of the present invention can provide the connector cover assembly, for the protection of with the connector of optical fiber distribution frame with outside plant.According to example embodiment, this assembly can comprise lid, and the size of this lid makes it utilize anchor clamps and/or the cover in position gone up to hold connector and the joints of optical fibre.This assembly also can comprise connector and clip.In an example embodiment, the joints of optical fibre can be installed on the optical fiber, and optical fiber can be by cable protection.In specific example embodiment, cable can have the diameter of about 4.8mm; Yet, can use other cable diameters and not deviate from the present invention.According to example embodiment, before with connector termination optical fiber, clip and connector can slide on the cable.Can use the program mounted connector of standard then.Connector can insert the openend of lid then, causes the reliable environmental sealing at the interface at lid-connector.Clip can be placed on the small end of connector and be fixed, and makes connector be fixed to cable, and makes connector form reliable environmental sealing at the interface at connector-cable.
In specific example embodiment, lid and connector can be molded rubber components.For extreme environment, can use silicon rubber.According to the restriction of environment and cost, can use other rubber, comprise neoprene, EP rubbers (EPDM), fluorosioloxane rubber, fluorocarbons etc.
In specific example embodiment, clip can be that cable is pricked knot (tie), bolt clip, button gripping clip, spring clamp or hose clamp.Clip can be made by the material of anti-ecological deterioration.For example, clip can be made by thermally-stabilised and/or ultraviolet (UV) stable nylon.
According to example embodiment of the present invention, the interference fit between the smooth interior surfaces by serum cap and the smooth outer surface of rubber plug provides reliable damp proof barrier.According to example embodiment of the present invention, clip can provide the extra circumference to the connector internal diameter to compress at the cable external diameter, and this can be with connector and cable sealing.According to example embodiment of the present invention, the friction between the rubber components and/or interference fit can remain on lid on the appropriate location of connector.Correspondingly, rubber components can guaranteed reliable sealing under temperature and the environmental baseline on a large scale.
Make the design of the fixing lid of lid different with using belt, embodiments of the invention can be so that lid can be protected connector safely, and also can be so that lid can easily be removed when expectation.In addition, when the discrete cell build-in services of preparing in the house, clip can be released and connector can upwards slide at cable.Cable can enter by the mounting hole that gets out in windowsill.Connector can slip into mounting hole downwards on cable then, and wherein, connector can help to seal this mounting hole.Because do not use belt, so after cap assemblies removes, on cable or connector, can not have adhesive residue.
Embodiments of the invention use interference fit that lid is attached to connector, and connector/cable interface can fix and seals with clip.These example embodiment are different with the lid of prior art shown in Figure 1, and Fig. 1 illustrates for end cap 110 is attached to and covers 102 bayonet socket limiting mechanism 104.Prior art also uses the liner in the cap to come sealing cap/cable interface, but prior art and unexposed for the clamp device of further fixing and seal this interface.
Embodiments of the invention also are different from the lid of prior art as shown in Figure 2.For example, prior art shown in Figure 2 is included in the pulling eye 204 that covers in 202, bayonet socket 214 or thread mechanism 212 in lid 202 and cord adaptor 208, and O shape ring 210, and these do not need in an embodiment of the present invention.
The various parts and the part that are used for providing connector cover assembly and system according to example embodiment of the present invention are described below with reference to the accompanying drawings.
