All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a pull-plug type conductive column.
In this embodiment, referring to fig. 1-2, the pluggable conductive pillar includes a cylindrical terminal body 1 made of a conductive material, wherein one end of the cylindrical terminal body is provided with a plugging hole 2, and the cylindrical terminal body is provided with a heat dissipation hole 3 communicated with the plugging hole.
Among the above-mentioned technical scheme, through set up the louvre with the intercommunication of spliced eye on the column terminal body, increase heat radiating surface area, improve the heat-sinking capability, heat dissipation that can be rapider when the heavy current passes through avoids leading electrical pillar because overheated and the damage appears, improves life and stability.
In addition, through setting up the louvre, reduce material, reduction in production cost can effectively reduce the whole weight of leading electrical pillar simultaneously, helps the lightweight design of product.
Specifically, the length of the heat dissipation hole is greater than 1/2 of the length of the columnar terminal body.
The length of the heat dissipation holes is improved, and the heat dissipation effect is guaranteed.
Specifically, a wrench groove 4 is arranged on the columnar terminal body at one end deviating from the plug hole; the wrench groove is a hexagonal groove or a straight groove.
Through setting up the spanner groove, be convenient for to the dismouting of inserting formula conductive pillar.
