Advantage

● Long life cycle: 10,000 times

● No mold opening, suitable for customization

● The elasticity can be accurately adjusted and adjusted

● Save space and give designers more flexible configuration structure

● Provide customers with multi-origin production mode: SMT automatic production, plug-in

Needle shaft design

●Cut the hypotenuseIn order to ensure that the needle shaft is in 100% contact with the needle tube when working, we cut the end of the needle shaft in contact with the spring into a bevel,This design concept can ensure a stable bottom impedance.Product advantages: The resistance is small and stable, which can ensure that the needle shaft and the tube wall are in close contact to reduce the probability of instantaneous power failure

Needle shaft design

Back drilling

●Back drillingThis design is the best choice for a small size connector. The small size can meet the elasticity requirements of customers, because the spring length of this design can exceed the length of the needle tube. In some cases where space is limited, The needle shaft is hollowed out to get more spring assembly space, so stable spring force and relatively more compression stroke can be obtained for customers to choose. To1. Easy turning and low cost2. Can strive for space for spring placement3. Shorten the height of the product4. The phenomenon of no pin stuck in static stat

Needle shaft design

Cone bottom shape

●Cone bottom shapeThis design is the best choice for connectors that require high concentricity, because the spring of this design can be directly sleeved on the cone tail needle of the needle shaft.The needle shaft is subjected to vertical force, so the deflection of the shaft is relatively small.The bottom of the needle shaft is cone-shaped, and the cone tail is placed in the air in the spring to reduce the chance of needle shaft shaking1. Easy turning 2. Low cost 3. Small deflection 4. Since the bottom cone end of the needle shaft is placed in the air inside the spring, it is in close contact with the top of the spring.Therefore, the shaking of the needle shaft is quite small
