JUMPER PIN

A pin for use with a jumper is illustrated. The jumper defines two insertion holes. The pin includes a main rod and at least one engaging portion. The main rod includes an arc-shaped first end, an opposite second end, and a sidewall between the first end and the second end. The at least one engaging portion connected to the main rod and comprising a top end lower than the first end of the main rod, the top end being configured to be inserted into one of the insertion holes of the jumper.

DETAILED DESCRIPTION

Embodiments of the present disclosure are now described in detail, with reference to the accompanying drawings.

Referring toFIG. 1, a jumper pin100a,for use with a jumper, includes a main rod10, an engaging portion20, and a connecting portion30connecting the engaging portion20to the main rod10.

Referring toFIGS. 2-3, the jumper pin100bincludes two engaging portions20and two connecting portions30, and the jumper pin100cincludes three engaging portions20and three connecting portions30.

The main rod10includes an arc-shaped first end11, an opposite second end12, and a sidewall13between the first end11and the second end12. A top end of the engaging portion20is lower than the first end11of the main rod10. In the embodiment, the connecting portion30is perpendicularly connected to the sidewall13and the engaging portion20.

Referring toFIGS. 4-5, one end of the jumper pins100is soldered to a circuit board200, and a number of jumpers300are installed to connect each pair of adjacent jumper pins100. The jumpers300each define two insertion holes (not shown) for receiving the top ends of two adjacent engaging portions20. Thus, the jumpers300electrically connect the two adjacent jumper pins100together. In the present disclosure, the top end of the engaging portion20is lower than the arc-shaped first end11, thereby preventing the jumper pin100from hurting the fingers of the users.
