Abstract
A pressure connected probe comprises a sleeve component and a probe element. The sleeve component is provided with a high current hollow needle shaft and a high current hollow needle principle body. The high current needle shaft is arranged at the front end of the high current hollow needle principle body. The probe element is penetrated through the high current needle shaft. The probe element is provided with a grounding needle, a grounding casing and an insulation casing. The grounding casing is covered on the grounding needle, and the insulation casing is covered on the grounding casing, thus a pressure connected probe is formed, wherein the grounding needle can be take out to replace from the front end and is convenient to repair damage, which also lowers repair cost. The insulation casing is pressing covered on the grounding casing, which can lower the accuracy requirement of mold and simplify the mold design, so as to reduce the cost of mold, and the eccentric phenomenon will not happen in the grounding needle. Furthermore, the needle shaft cross-section can avoid gliding on the contact surface.
