Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an industrial connector structure. Background Art

[0002] Industrial connectors are currently widely used in industrial equipment and systems as components for electrical, mechanical or optical connections; they are used to connect different devices, systems, modules or sensors together to ensure the effective transmission of signals, data or power; many industrial connectors adopt a modular design and can combine different types of connector modules according to different application requirements, such as: power connection, data transmission, fiber optic transmission, etc., thereby providing flexible connection solutions.

[0003] After searching, it is found that there are various connection methods for industrial connectors in the prior art. In order to solve the poor contact at the joints, many connection methods have been designed, including crimping, screwing, spring leaf, etc. Although these methods can temporarily solve the problem of core wire falling off at the beginning of installation, the tail wire, i.e. the main wire, is often shaken and touched, and even twisted. Even if the joint is tight, it may become loose or even break due to stress concentration. Therefore, we propose a new industrial connector that can prevent poor contact at the core wire connection due to twisting of the main wire. Summary of the invention

[0016] 3. By setting the transition wire made of soft wire material and the compression spring, it is possible to avoid accidental wrong insertion, which may cause the male core rod to be continuously stressed and then bent or skewed. With this setting, once forced extrusion occurs, all the male core rods will be axially withdrawn until the socket of the plug sleeve is subjected to the main extrusion force, thereby effectively protecting the male core rod.

[0017] 4.
