Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a crown spring connector with good buffering effect. Background Art

[0002] Currently available pogo pins typically consist of a shaft and a tube. A spring positioned between the two provides a reaction force, which acts on the shaft and tube, forcing them into contact and achieving electrical continuity. During use, the tube is typically soldered to a solder pad on a circuit board, with the shaft acting as a contact point to connect with a mating terminal to achieve electrical continuity.

[0003] However, there are some problems with the existing technology: since the tail of the needle head of the crown spring type spring thimble is long and fixed by the crown spring, under the action of a certain force, the tail of the needle head will move to the bottom of the crown spring. Without the action of the buffering force, it cannot be reset, causing the connector to be unable to power on. Therefore, we propose a crown spring connector with good buffering effect. Utility Model Content

[0004] In response to the problems existing in the above-mentioned technology, the utility model provides a crown spring connector with good buffering effect, which solves the problem that the tail of the needle of the crown spring spring thimble is long and fixed by the crown spring. Under the action of a certain force, the tail of the needle will move to the bottom of the crown spring. Without the action of buffering force, it cannot be reset, causing the connector to be unable to power on.

[0026] like Figure 1As shown, the needle shaft 1 includes a head 12, which is located at the upper end of the limit platform 22. The lower end of the head 12 is connected to a detachable rod 13, which passes through the sleeve and extends into the interior of the connecting tube 3 to be connected to the crown spring body. The outer wall of the rod 13 located inside the sleeve 2 is sleeved with a first spring 11, and the two ends of the first spring 11 are in contact with the head 12 and the outer wall of the connecting tube 3 respectively; when the head 12 is affected by force, it drives the rod 13 downward at the same time, and drives the first spring 11 during the movement. Under the action of the force, the first spring 11 is deformed and compressed inside the sleeve 2. When the head 12 is no longer pressed by force, the first spring 11 buffers and resets, driving the head 12, and the head 12 drives the rod 13 to reset, so as to prevent the rod 13 from being unable to reset after moving to the lower end of the crown spring body 5.

[0027] like Figure 2 As shown, a threaded hole 121 is provided on the lower end surface of the head 12 for connecting to the rod 13 .

[0030] Working principle of embodiment 1:

[0031] During use, under the influence of the force on the head 12, the rod 13 is driven to move downward, and the first spring 11 is driven during the movement. Under the action of the force on the first spring 11, deformation occurs inside the sleeve 2 and compression occurs. When the head 12 is no longer pressed by the force, the first spring 11 buffers and resets, driving the head 12, and the head 12 drives the rod 13 to reset; when the head 12 is forced to move, it drives the sleeve downward, and the second spring 42 is deformed by the force of the sleeve 2 moving downward, and is compressed downward on the outer wall of the connecting rod 41.
