Guide line sealing connector

Abstract

The invention is suitable for the field of sealing technologies and provides a guide line sealing connector. The guide line sealing connector comprises a plastic connector body. The center of the plastic connector body is provided with a through hole for a guide line to penetrate through, the plastic connector body is provided with a protruded screwing portion, an inner end portion and an outer end portion, the periphery of the inner end portion and the periphery of the outer end portion are provided with outer threads, a seal ring is sleeved on the inner end portion, the annular end face of the outer end portion and the outer end portion are integrally provided with a sawtooth structure consisting of a plurality of sawteeth, the root portions of the sawteeth are larger than the tip portions, the portions from the root portions to the tip portions are streamline-shaped, and the sawtooth structure is provided with a guide line sealing part in a surrounding mode. The guide line sealing connector further comprises a plastic nut provided with a hollow cavity and capable of being screwed at the outer end portion. By means of technical improvement, the guide line sealing connector fully utilizes the elasticity of structural parts and plastic to achieve the sealing effect, is easy to assemble, high in sealing reliability and low in cost.

Description

technical field [0001] The invention belongs to the technical field of sealing, and more specifically relates to a wire sealing joint. Background technique [0002] At present, the input cables of outdoor electronic products generally use compression nuts to squeeze the packing rubber sealing ring, or directly install rubber protective wire sealing rings where the outer layer of the cable enters the shell, or use glue to solidify the gap at the structure to To achieve the sealing effect. The use of compression nuts has the problems of high cost and low reliability, because the compression nuts are generally metal products, and the price is relatively high; moreover, the metal compression nuts are exposed to the external environment, and are easy to rust and bite on the product shell, which is reliable. Sex is low. Although the cost of the wire protection sealing ring is low, the safety performance is low. The rubber product is easily affected by corrosive gas and ambient t...

Problems solved by technology

The use of compression nuts has the problems of high cost and low reliability, because the compression nuts are generally metal products, and the price is relatively high; moreover, the metal compression nuts are exposed to the external environment, and are easy to rust and bite on the product shell, which is reliable. Low sex

Although the cost of the wire protection sealing ring is low, the safety performance is low. The rubber product is easily affected by corrosive gas and ambient temperature in the external environment, which weakens the rubber properties and loses the sealing function.

The glue solidification method is generally to add epoxy resin to the joint seal. This method has high reliability, but the process of adding epoxy resin is cumbersome and pollutes the environment. This method is generally seldom used.
