1. Technical Field
The present disclosure relates to a jumper assembly.
2. Description of Related Art
In electronic devices, particularly, computers, jumpers are conductors used to close a break in or bypass part of an electrical circuit. Jumpers are typically used to set up or adjust printed circuit boards, such as the motherboards of the computers. Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, with each group having at least one pair of contact points and often more. In general, each contact in a jumper block terminates in a small metal pin. An appropriately sized conductive sleeve called a jumper, or more technically, a jumper shunt, is slipped over the pins to complete the circuit. When the jumper is used on the jumper block, two pins of the jumper block are connected to each other to form a closed circuit (ON state). Therefore, current may flow between the two pins. When the jumper is removed, the two pins are an open in the circuit (OFF state). However, once the jumper is removed from the motherboard, the jumper may be lost or misplaced and cannot easily be found because the jumper is very small, which will bring inconvenience to the user.
Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The first base 10, the second base 20, and the third base 30 are all mounted on the circuit board 100 in a line. The second base 20 is located between the first base 10 and the third base 30. The first base 10 includes a first pin 11 electrically connected to the circuit board 100. The second base 20 includes a second pin 21 electrically connected to the circuit board 100. The second pin 21 includes a pole 211 electrically connected to the circuit board 100 and a limiting portion 213 perpendicularly extending from a top end of the pole 211. The third base 30 includes a third pin 31 electrically connected to the circuit board 100. The first pin 11 and the third pin 31 each have a tapered top end.
Two cushions 13 are formed at opposite corners on a top surface of the first base 10, two cushions 23 are likewise formed on a top surface of the second base 20, and two cushions 33 are likewise formed on a top surface of the third base 10.
The jumper 40 includes a substantially rectangular main body 41 and an arc-shaped handle 43 extending from a top of the main body 41. The main body 41 defines a first through hole 45 and a second through hole 47 from top to bottom. A first conductive portion 451 is received in the first through hole 45. A second conductive portion 471 is received in the second through hole 47 and electrically connected to the first conductive portion 451. The first conductive portion 451 is a metal clip which can clamp onto the second pin 21. The second conductive portion 471 is a metal clip which can clamp onto the first pin 11 or the third pin 31.

In this embodiment, the first pin 11 and the third pin 31 are of equal height. The exposed portion of the pole 211 is longer than the sum of the height of the exposed portion of the first pin 11 and a height of the main body 41, to allow the main body 41 to disengage from the first pin 11 or the third pin 31 when the jumper 40 is blocked by the limiting portion 213.
In other embodiments, the first base 10, the second base 20, and the third base 30 may be arranged in a triangle formation.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
