The screwed plug connector comprises an arc-shaped cap, a screwed connection structure and a chamfer, wherein the arc-shaped cap is located on the topmost end; a prism body structure is arranged under the arc-shaped cap; the prism body structure and the arc-shaped cap are cast into a whole; the screwed connection structure is cast under the prism body structure; the secondary threads are arranged under the prism body structure.

Description

technical field [0001] The invention belongs to the field of manufacturing technology, and in particular relates to a plug connector with a secondary thread. Background technique [0002] The current plugs have poor chemical resistance, are highly corroded by sewage and waste water, and are corroded by soil rotten substances. In the ultra-low temperature environment of minus 60°C, there are phenomena of freezing cracks, swelling and water leakage, and cannot adapt to different equipment specifications. Sex is poor. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and proposes a plug connector with a secondary thread, which has exquisite structural design, unique technology, fine processing, energy saving, noise reduction, safety and environmental protection, and reduced labor intensity. [0004] The technical solution of the present invention is: a screw plug connector with a secondary thread, including an arc-shaped cap, a ...
