Production process description


Corrugated conduit are mainly used to compensate for axial displacement, can also compensate for lateral displacement or axial and transverse synthetic displacement, with the ability to compensate for angular displacement. In order to ensure that it play a better application effect, the production process of manufacturing process is essential, the following, to tell you about these two processes.


1. Shaping process
Corrugated conduit after forming, due to elastic rebound to the corrugated pipe spacing, wave type and suction meter requirements are different, must be plastic. For the processing of hardened material made of corrugated conduit, generally by hand and mechanical shaping two methods. For the dispersion of hardened material of the corrugated conduit, it will be loaded into the aging fixture aging, so that the corrugated conduit shape, in order to achieve the shaping effect.


2. Stabilization process
Corrugated conduit in the process, will produce internal stress, so that the shell and the geometric size of instability. The purpose of stabilizing the corrugated conduit is to eliminate stress, stabilize performance, and stabilize the geometry. The stabilization of corrugated conduit includes heat stabilization process and mechanical stabilization process. Under normal circumstances only for heat stability treatment, there are special requirements only when the need for mechanical stability.


The precise processing of the corrugated conduit, will be able to effectively guarantee its quality, to ensure its good application effect.

2, if the device has good anti-electromagnetic interference performance, its production is not restricted <br />
<br />
Equipment manufacturers to meet the requirements, increasing demand for the use of shielded connectors, The shielded cable can be connected using a conductive housing connected to a shielded cable. Care should be taken when using the circular connector to carefully introduce the shield of the cable to the shield end of the connector, Therefore, it is preferable to have a 360 degree circular support. If the shield is securely connected to the conductive housing, a good shielding value can be achieved. <br />
<br />
Pure plastic connectors do not have a metal housing. The shield of the cable can not be connected directly. <br />

Summary: it is important to achieve the integrity of the plug and socket connection between, and make it re-connection between the instrument base. <br />

Fire 94V level classification

Plastic flame retardant grade from HB, V-2, V-1 to V-0 step by step increments:

HB: UL94 standard in the lowest flame retardant rating. For samples of 3 to 13 mm thick, the burning rate is less than 40 mm per minute; for samples less than 3 mm thick, the burning rate is less than 70 mm per minute; or extinguished before the 100 mm mark.

V-2: After two 10-second burning tests on the sample, the flame is extinguished in 60 seconds. There may be a burning substance that falls off.
