  There are three structures:

  1. Inclined surface with ball: In order to make the contact more stable, a steel ball Aka insulating ball is added to the needle to reduce the current passed by the spring. The steel ball in the spring needle is in stable contact, so the electrical performance will be better.

  2. Bevel structure: In order to ensure 100% contact between the needle and the needle tube when working, we cut the end of the needle that contacts the spring into a bevel. This design concept can ensure a low and stable contact impedance and a stable conduction of the product.

  3. Back-drilling: This design is a better choice for small-sized connectors. Can meet the elasticity requirements of customers. The length of the matching spring of this design can exceed the length of the needle tube. In the case of limited space, the design of reverse drilling can obtain stable elastic force and stroke.

  4. Double contact: This structure is a good choice for connectors with high concentricity requirements, because this design spring can be directly sleeved on the cone tail needle of the needle shaft, so that the needle shaft is vertically stressed, so the needle shaft The yaw will be relatively small.

  The design of pogopin needle tube will be designed in accordance with the customer's structural space and product functional requirements as well as the guarantee of life. Can provide common and opposite designs for selection.

  Processing technology: Precise computer machining can ensure the dimensional accuracy very well, the accuracy can reach 0.01mm, and the product life can reach 10,000 to 1 million times. Spring material: stainless steel SUS304, piano steel wire.

  The above three structures can be combined to form a complete pogopin product, and the plastic bottom can be combined to form a pogopin of various specifications.
