Description

Jumper

The present invention relates to a jumper, and more particularly to a jumper for controlling the interconnection of specific pins of a connector on a computer motherboard.

There are usually connectors for the user to set on the motherboard. These connectors include a plurality of pins on the motherboard and jumpers for the user to set which pins are connected to each other. As shown in FIG. 1 is a schematic diagram of the use state of the existing jumper. A connector 30 including three pins can be connected in three ways: pin A and pin B are turned on, pin B and pin C are turned on, and all pins are not connected. By way of example, these three connections are achieved by placing jumper 20 on pin A and pin B, placing jumper 20 on pin B and pin C, respectively, and not using jumper 20. When there are other electronic components around the position of the connector 30, it is difficult to insert the jumper 20 after the removal, and the removed jumper 20 is easily lost due to its small size.

In view of the above, it is necessary to provide a jumper that facilitates the interconnection of specific pins of a connector on a computer motherboard.

A jumper for controlling a connection between specific pins on a connector, the jumper including a jumper housing, a switch and a plurality of guides, the bottom of the jumper housing corresponding to the pins on the connector The plurality of slots are disposed in the corresponding slots and are electrically connected to the pins on the connector. The top of the slots is provided with a slide, and the switch is slidably disposed in the slide And two of the guide sheets can be selectively electrically connected.

Compared with the prior art, the switch switch controls the interconnection between the specific pins of the connector through the guides, thereby avoiding the insertion and removal of the jumper during the connection of different pins in the prior art, and also preventing the removal. The jumper caused by the smaller jumper is lost.

Referring to FIG. 2 and FIG. 3 together, a preferred embodiment of the jumper of the present invention includes a jumper housing 11, a switch 12 and a plurality of guides 13. The jumper housing 11 is a rectangular body. The bottom of the jumper housing 11 is provided with a plurality of slots 112 corresponding to the pins on the motherboard connector. The top of the slots 112 is provided with a slide 113. The jumper housing The top of the 11 is provided with an opening 111 communicating with the slide 113.

The guide piece 13 is made of a conductive material, and includes a connecting body 131. The two side edges of the lower side of the connecting body 131 extend in the same direction and extend outwardly from the two side walls 132. The two side walls 132 extend obliquely upward to form two elastic pieces 133. The top edge of the connecting body 131 is bent in a horizontal direction to form a top wall 134. The guide pieces 13 can be firmly fixed in the slots 112. When the jumper 10 is inserted into the connector, the guide pieces 13 can clamp the pins on the connector so that the jumper 10 and the jumper 10 The pins are stable in docking and the electrodes 13 are electrically connected to the pins.

The lower part of the switch 12 is a rectangular slider 121. The lower surface of the slider 121 is coated with a conductive material. The slider 121 is disposed in the slide 113 and transmits the conductive material on the lower surface thereof to the top of the guides 13. The wall 134 is electrically connected. The upper portion of the switch 12 is a square handle 122. The handle 122 is exposed from the opening 111 at the top of the jumper housing 11. The handle 122 is pushed to slide the slider 121 to slide in the slide 113.

The different positions of the switch 12 correspond to different connection relationships of the pins on the connector. When the handle 122 is toggled to cause the switch 12 to slide to a different position, the adjacent two guide pieces 13 are connected to each other through the conductive material at the bottom of the switch 12, and are connected to the connector corresponding to the guides 13 The pins are also connected to each other, thereby achieving interconnection between specific pins.

Referring to FIG. 4 and FIG. 5 together, when the jumper 10 is mated with a pin of a connector 40, the jumper 10 is inserted into the connector 40. When the handle 122 is toggled so that the switch 12 is in the left position, the stitch D and the stitch E on the connector 40 are turned on; when the handle 122 is toggled so that the switch 12 is in the right position, the stitch E on the connector 40 The pin F is turned on; when the handle 122 is toggled so that the switch 12 is in the intermediate position, the pins D, E, and F on the connector 40 are not turned on. When the jumper 10 is used to control the connection of different pins of the connector 40, it is only necessary to toggle the switch 12 at different positions.

Please refer to FIG. 6 and FIG. 7 , which are schematic diagrams of another preferred embodiment of the jumper of the present invention. When the changeover switch 52 of the jumper 50 is in the left position, the pins 1 and 2 on the connector 60 are turned on; when the changeover switch 52 is in the intermediate position, the pins 3 and 4 on the connector 60 are turned on; when the switch is switched When the 52 is in the right position, the pins 5 and 6 on the connector 60 are turned on. When the jumper 50 is used to control the connection of the different pins of the connector 60, it is only necessary to toggle the switch 52 to a different position.

The jumper of the present invention is not limited to the configuration in the above embodiment, and may be changed correspondingly depending on the number of pins of the connector of a specific application. The jumper of the present invention facilitates the user to set the connector to a certain extent. The operation of the jumper is often inserted and removed, and the loss of the jumper caused by removing the smaller cross-over is also avoided.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
