Talk About The Design Principle Of Micro Duct Connectors

Micro Duct Connector, as an indispensable accessory for connecting Micro-duct, runs through the entire air blowing construction. Today, I will show you how engineers combine the problems encountered in actual construction in designing products to produce a perfect product.

Technical Background

The traditional Micro Duct Connector has an open window structure. After being installed underground, it is very easy for dirt to enter the interior of the product, thus affecting the sealing. Once an air leak occurs, it is necessary to replace the product with a new one, which is very time-consuming and labor-intensive. Secondly, the open window structure makes it necessary to thicken the wall thickness of the product, so the product volume is also larger, and the demand for raw materials also increases.

Technical Update Highlights

The update adjustment is characterized in that: the tubular body is provided with an annular groove, the lower end face of the tubular plastic sleeve is inserted into the end of the body, the protruding tabs on the outer wall of the plastic sleeve are inserted and stuck in the groove, and there are two rings in the plastic sleeve. Step, the outer edge of a ring-shaped circlip is pressed on the step near the lower end face of the plastic sleeve, a button is inserted into the plastic sleeve, the raised tab on the outer wall of the button is pressed on the step near the upper end face of the plastic sleeve, the lower part of the button The end face is pressed on the circlip; when the Micro-duct is inserted into the plastic sleeve, the Micro-duct passes through the circlip and the inner ring of the circlip abuts against the outer wall of the Micro-duct. Compared with the open window, the hidden window is adopted, which reduces the entry of dirt into the product and greatly improves the service life of the product. Its small size is convenient for smooth installation and use in narrow places.

Installation

In order to explain the technical adjustment more clearly, the following will briefly introduce the accompanying drawings that need to be used in the description. Obviously, the accompanying drawings in the following description are only the structural drawings of the product. to complete the installation of the product.

Figure 1.Product details

The clever design of the recessed window in the form of a groove can not only ensure sufficient strength of the product, but also greatly reduce the volume of the product. And no additional aids are required during installation. The interior of the product uses a metal lock made of stainless steel. The maximum pressure can reach 28bar, which meets the situation that the high-pressure gas will not fall off through the connection.
