It is made to connect more solid and reliable, because using pressure tongue structure, pressure root of the tongue portion is wider globoidal structure, and this globoidal structure makes
Become gradually pressing structure, so that pressure tongue portion is deformed upon, flat lie prone on contact pin, increase contact area and frictional force, when outwards pulling out
When going out contact pin, stop contact pin from moving out, form dynamic protection, drastically increase well connecing of electric connector contact pin and pin hole
Tactile performance, and make connection more stable, safe and reliable.
The annular taper guide frame that the setting of jack socket joint one end head caves inward, it is to avoid pin hole internal diameter occurs larger change
Change, can effectively ensure that jack and contact pin to slotting when concentricity, pin hole body is laid with through hole, is conducive to the sky within pin hole
Gas is discharged rapidly, makes in plating processes, and plating solution is easier to be full of inside and outside pin hole, fully and uniformly plates inside and outside full pin hole, carries
High yield quality.
This utility model structure is simple, and grafting is reliable and stable, and chucking power is powerful, and indefatigability deforms, and effectively improves syringe needle
With pin hole connection reliability, and effectively extend pin hole service life, practical.
