A production method of double waterproof groove optical cable transfer box

Abstract

The invention relates to a communication device and particularly relates to a method for producing a double-waterproof-groove optical cable cross-connecting box. The method comprises the steps of placing a side plate on a specific bending and drawing composite die to bend the U-shaped side plate and draw waterproof grooves on two end faces of the U-shaped side plate in one step; forming waterproof grooves in one side face of a top plate and one side face of a bottom plate in a milling mode respectively; welding the side plate and the top plate together, and welding the side plate and the bottom plate together; placing a box door on a drawing die to form protruding grooves which are matched with shapes of the waterproof grooves of a box body in a drawing mode; spraying waterproof coatings onto an inner cavity of the box body and the inner wall of the box door; performing mechanical strength tests, assembly tests, airtightness tests, combustion performance tests and grounding conductive performance tests on the optical cable cross-connecting box; and performing alcohol solvent resistance tests on the waterproof coating of the inner cavity of the box body. According to the method, the production cost is low, the waterproof effect of products is good, the mechanical performance is high, and the product quality is guaranteed.

Description

technical field [0001] The invention relates to communication equipment, in particular to a production method of an optical cable junction box with double waterproof grooves. Background technique [0002] The optical cable transfer box is used for outdoor optical fiber distribution equipment at the node of the backbone optical cable and distribution optical cable in the outdoor optical cable access network, to realize the direct connection, disk storage, and optical fiber bottom fusion splicing and dispatching functions of the optical fiber, and can be used for outdoor landing and overhead installation. . [0003] The optical cable transfer box is an optical cable connection device installed outdoors. The most fundamental requirement for it is to be able to withstand drastic changes in climate and harsh working environments. It needs to be waterproof, moisture-proof, dustproof, and impact-resistant. Therefore, the requirements for waterproof, moisture-proof, dust-proof, imp...

Problems solved by technology

However, these two waterproof methods are not very effective in practical applications.

Moreover, the impact resistance of these two types of optical cable transfer boxes is relatively poor due to the lack of tight fit between the box body and the box door.
