Abstract
A pogo pin whose elastic force can be adjusted according to a contacting direction is disclosed. According to an aspect of the present invention, provided is a pogo pin with adjustable elastic force, including: a housing; plunger pins mounted on ends of the housing to directly contact a measurement object; and a spring installed inside the housing to provide elastic force so that the plunger pin contacts the measurement object, wherein a local fixing part protruding inward is formed on one side of the housing so that a first position of the spring can be pressed and fixed.
Claims10
A pogo pin with adjustable elastic force, comprising:
- a housing;
- an upper plunger pin mounted on an upper portion of the housing to directly contact a measurement object;
- a lower plunger pin mounted on a lower portion of the housing;
- and
- a spring installed inside the housing to provide elastic force so that the upper and lower plunger pins contact the measurement object,
- wherein a local fixing part protruding inward is formed on one side of the housing so that a first position of the spring can be pressed and fixed,
- wherein the spring includes an upper spring disposed between the local fixing part and the upper plunger pin, and a lower spring disposed between the local fixing part and the lower plunger pin,
- wherein a length from the local fixing part to the upper plunger pin is longer than a length from the local fixing part to the lower plunger pin,
- wherein a number of turns of the upper spring is greater than a number of turns of the lower spring, and
- wherein elastic force that the upper spring provides to the upper plunger pin is greater than elastic force that the lower spring provides to the lower plunger pin.
