Jumper

The present invention relates to a jumper, and more particularly to a jumper for controlling the interconnection of 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. FIG. 1 is a schematic diagram showing the state of use of the conventional jumper 110. A connector 120 including three pins can be connected in four ways: pin A and pin B are turned on, pin B and pin C are turned on, and all pins are connected. When not connected and pin A and pin C are turned on, the first three connection modes can be placed in pin A and pin B by jumper 110, pin B and pin C in jumper 110, and jumper 110 not used. This is achieved, but the jumper 110 cannot achieve the connection of the pin A and the pin C. Moreover, when there are other electronic components around the position of the connector 120, it is difficult to insert the jumper 110 after the removal, and the removed jumper 110 is also easily lost due to its small size.

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

A jumper for controlling a connection between pins on a connector, the jumper comprising a jumper housing, a switch and a plurality of electrical guides corresponding to the pins of the connector, the jumper housing Correspondingly, there is a slot for receiving the electrical guiding sheets, and the bottom of the guiding pieces can be matched with the stitches on the connector. Electrically connected, the tops of the two spaced apart guide sheets respectively extend from the same side to an extension portion, and the two extension portions are not connected, and the tops of the slots are connected to form a slideway, and the switch is movably disposed on the slide The inside of the track can be electrically connected to the top of the two adjacent guide pieces or the extension of the two spaced apart guide pieces.

Compared with the prior art, the switch can control the electrical connection between any two pins of the connector by selectively connecting the top of the two adjacent guides or the extension of the two guides spaced apart, thereby avoiding the conventional knowledge. In the technology, the plug-in operation of the jumper during the connection of different pins can also prevent the loss of the jumper caused by the small-sized jumper.

Referring to FIG. 2 and FIG. 3 together, a preferred embodiment of the jumper 20 of the present invention includes a changeover switch 210, a jumper housing 220 and three guides 230. The number of the guides 230 can be increased according to the actual needs. In the present embodiment, only three are described as an example.

The jumper housing 220 is a slightly inverted "7"-shaped square cylinder. The bottom of the jumper housing 220 is provided with three slots 224 corresponding to the pins on the motherboard connector. The slots 224 are connected at the top. A slide 226 is formed, and a top of the jumper housing 220 is provided with a "T" shaped opening 222 communicating with the slide 226. The distance between the slots 224 on both sides is greater than the length of the slider 212.

The guiding piece 230 is made of a conductive material, and includes a connecting body 232. The two side edges of the lower side of the connecting body 232 extend perpendicularly and outwardly from the two side walls 234. The two side walls 234 extend obliquely upward to form two elastic pieces 236. The top edge of the connecting body 232 is bent in a horizontal direction to form a top wall 238, two outer The top wall 238 of the side guide piece 230 extends toward the same side to the right-angled extension 239. The two extensions 239 are opposite and not connected. The distance between the two extensions 239 is smaller than the length of the slider 212. The guide piece 230 can be firmly fixed in the slot 224. When the jumper 20 is inserted into the connector, the guide piece 230 can clamp the pin on the connector to make the jumper 20 and the pin The docking is stable and the guide 230 has a good electrical connection with the pin.

The lower part of the switch 210 is a rectangular slider 212. The lower surface of the slider 212 is coated with a conductive material. The slider 212 is disposed in the slide 226 and can pass through the conductive material of the lower surface thereof. The top wall 238 or the extension portion 239 is electrically connected. The upper portion of the changeover switch 210 is a square handle 214. The handle 214 is exposed from the opening 222 at the top of the jumper housing 220. The handle 214 is pushed to manipulate the slider 212 at the opening. Slide within 222.

The different positions of the switch 210 correspond to different connection relationships of the pins on the connector. When the handle 214 is toggled to cause the switch 210 to be slid to a different position, the two adjacent guides 230 or the two extensions 239 are connected to each other through the conductive material at the bottom of the switch 210, and the guides 230 are The pins on the corresponding connector are also connected to each other, thereby achieving the interconnection between the two pins.

Referring to FIG. 4 and FIG. 5 together, when the jumper 20 is mated with the pins of a connector 30, the jumper 20 is inserted into the connector 30. When the handle 214 is toggled so that the switch 210 is in the X position, the pin D and the pin E on the connector 40 are turned on; when the handle 214 is toggled so that the switch 210 is in the Y position, the pin E on the connector 40 And the pin F is turned on; when the handle 214 is toggled so that the switch 210 is in the middle position, Pins D, E, and F on the connector 40 are not turned on; when the handle 214 is toggled so that the switch 210 is in the Z position, the stitch D and the stitch F on the connector 40 are turned on. When the jumper 20 is used to control the connection of different pins of the connector 30, it is only necessary to toggle the switch 210 at different positions.

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's operation of inserting and removing the jumper frequently when setting the connector, and also avoids the loss of the jumper caused by removing the smaller cross-over.

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