Jumper

A jumper includes a casing, and two conductive members. The casing defines a first receiving space in a first end, and a second and a third receiving spaces in a second end opposite to the first end. The conductive members are received in the first receiving space.

BACKGROUND

1. Technical Field

The present disclosure relates to a jumper.

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 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 size of the jumper is very small, which will bring inconvenience to the user.

DETAILED DESCRIPTION

Referring toFIGS. 1 and 2, an embodiment of a jumper includes a first portion2and a second portion3integrally formed on the first portion2. In other embodiments, the second portion3may be detachably connected with the first portion2.

Referring toFIG. 3, the first portion2includes a substantially quadrate casing20and two conductive members22. The casing20includes a proximal end connected with the second portion3and a distal end (not labeled) far way from the second portion3. The casing20defines a first receiving space25extending from the distal end to receive the conductive members22. The casing20is made of dielectric material. The conductive members22are made of conductive material.

Each conductive member22includes a base plate220, a first touching sheet221, a second touching sheet222, a first clipping sheet223, and a second clipping sheet225. The first and second touching sheets221and222are parallel to each other and protrude from a top end and a bottom end of the base plate220in the same direction, coplanar with the base plate220. The first and second clipping sheets223and225perpendicularly protrude from opposite sides of the base plate22, respectively. A distance between the first and second clipping sheets223and225gradually reduces from the top end to the bottom end of the base plate220.

A protrusion226protrudes from an inner surface of the first receiving space25. The protrusion226includes a blocking surface228at a bottom of the protrusion226. In assembly, the conductive members22are inserted into the first receiving space25through opposite sides of the protrusion226. A top of the second clipping sheet225of each conductive member22resists against the blocking surface228. The first touching sheets221of the conductive members22resist against each other. The second touching sheets222of the conductive members22resist against each other. Thus, the conductive members22are fixed in the first receiving space25.

The second portion3is substantially quadrate and made of dielectric material. The second portion3defines a second receiving space30and a third receiving space32in a distal end of the second portion3far away from the first portion2. The second portion3is engaged with two jumper pins A and B of a jumper block4of a motherboard100(shown inFIG. 4). A depth of the second and third receiving spaces30and32is equal to the length of the corresponding jumper pins A and B. A distance between the second receiving space30and the third receiving space32is equal to the distance between the corresponding jumper pins A and B.

Referring toFIGS. 4 and 5, in use, when the jumper pins A and B need to be connected together to form a closed circuit (ON state), the jumper pins A and B are respectively inserted into the first receiving space25of the jumper, with each latched between the first clipping sheet223and the second clipping sheet225of a corresponding conductive member22. The jumper pins A and B are electrically connected together by the conductive members22.

Referring toFIG. 6, when the jumper pins A and B need to be disconnected (OFF state), the jumper is moved up, and the jumper pins A and B are respectively inserted into the second and third receiving spaces30and32, which means no more lost jumpers.

In other embodiments, the outer surfaces of the first and second portions2and3forms a plurality of grip strips5to provide grip assistance for easier assembly and disassembly. The outer surfaces of the first and second portions2and3can also form different marks (for example different colors) to stand for ON state and OFF state.
