Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a shielding pogopin component. Background Art

[0002] Pogopin is a precision connector used in peripheral electronic products. The product is mainly composed of needles, needle tubes, springs, mushroom heads, tail plugs and other parts. The internal needle bevel structure ensures stable and reliable connection between parts and plays the role of transmitting current and signals. Due to the characteristics of large transmission current, small space occupation, precise contact, high-intensity application, etc., it is the first choice for the application of external interface connectors of peripheral consumer connectors;

[0003] The existing welding products on the market are all insulated with the nozzle facing upwards and exposed to the outside. When they are used in the following scenarios, they will more or less cause product failure. Scenario 1: If the exposed external rivet mouth is easily touched by consumers, the rivet mouth is most likely to accumulate dust when the customer uses it for a long time, whether intentionally or unintentionally; Scenario 2: The customer knows that the application environment is harsh, and during the test and evaluation, they deliberately simulate dripping sweat, salt water, dust or corrosive liquid into / contacting the rivet mouth. At this time, the above-mentioned device is easy to enter the product from the rivet mouth, which eventually leads to a large contact resistance or a PIN failure caused by the accumulation of telescopic needles. Therefore, we propose a shielded pogopin component to solve this problem. Utility Model Content

[0009] The connecting component is slidably arranged inside the shielding needle and is used to electrically connect the connecting wire harness with the preset charging circuit board.
