Abstract

An optical imaging lens includes a lens barrel, a front lens element, plural intermediate lens elements, and a rear lens element. The front lens element has a first central lens portion and a first assembly portion. The first assembly portion has a first front abutting section, a first front slanting surface section, and a first rear slanting surface section. Each of the intermediate lens elements has a second central lens portion and a second assembly portion. The second assembly portion has a second front slanting surface section and a second rear slanting surface section. The rear lens element has a third central lens portion and a third assembly portion. The third assembly portion has a third front slanting surface section.

An optical imaging lens comprising:

a lens barrel including a surrounding wall and a front wall connected to one end of said surrounding wall, said front wall having an abutting portion, and a first slanting surface portion connected to said abutting portion;
and
an imaging lens unit disposed in said lens barrel and including a front lens element, a plurality of intermediate lens elements and a rear lens element arranged in an order from an object side to an image side, each of said front lens element, said intermediate lens elements and said rear lens element having an object side surface facing toward the object side and an image side surface facing toward the image side;
said front lens element having a first central lens portion and a first assembly portion surrounding said first central lens portion, said first assembly portion having a first front abutting section and a first front slanting surface section disposed at said object side surface of said front lens element, and a first rear slanting surface section disposed at said image side surface of said front lens element;
each of said intermediate lens elements having a second central lens portion and a second assembly portion surrounding said second central lens portion, said second assembly portion of each of said intermediate lens elements having a second front slanting surface section disposed at said object side surface thereof, and a second rear slanting surface section disposed at said image side surface thereof;
said rear lens element having a third central lens portion and a third assembly portion surrounding said third central lens portion, said third assembly portion having a third front slanting surface section disposed at said object side surface of said rear lens element;
wherein said first front abutting section and said first front slanting surface section of said first assembly portion abut against said abutting portion and said first slanting surface portion of said front wall respectively, such that said first assembly portion is coupled with said front wall;
wherein said second front slanting surface section of said second assembly portion of a frontmost one of said intermediate lens elements abuts against said first rear slanting surface section of said first assembly portion, such that said second assembly portion of the frontmost one of said intermediate lens elements is coupled with said front lens element;
wherein said second front slanting surface section of said second assembly portion of a rear one of said intermediate lens elements abuts against said second rear slanting surface section of said second assembly portion of one of said intermediate lens elements that is immediately in front of said rear one of said intermediate lens elements to thereby couple said second assembly portions of said intermediate lens elements to each other;
wherein said third front slanting surface section of said third assembly portion abuts against said second rear slanting surface section of said second assembly portion of a rearmost one of said intermediate lens elements that is immediately in front of said rear lens element, such that said second assembly portion of the rearmost one of said intermediate lens elements is coupled with said rear lens element.
