Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a jumper device and an electronic device. Background Technology

[0002] CMOS (Complementary Metal-Oxide-Semiconductor) chips are used to store critical configuration information of a computer system, such as hardware settings, boot order, date and time. Due to user error, forgotten passwords, or system malfunctions, it is often necessary to clear the CMOS settings to restore the default state.

[0003] In traditional CMOS clearing methods, the CMOS clear jumper is typically a three-pin jumper. Normally, the jumper cap is connected to pins 1 and 2. During discharge, the jumper cap is placed on pins 2 and 3, and then the jumper cap is reinserted onto pins 1 and 2, thus clearing the CMOS. This method carries the risk of losing the jumper cap.

[0035] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0036] Combination Figure 1 , Figure 3 and Figure 5As shown, the jumper device provided in this embodiment includes a circuit board 1, a conductive element 2, and a driving element 3. The circuit board 1 has a first pin 11, a second pin 12, and a third pin 13 electrically connected to the read / write chip. The conductive element 2 is used to turn on the first pin 11 and the second pin 12 in a first position, and to turn on the second pin 12 and the third pin 13 in a second position. The driving element 3 is connected to the conductive element 2 and is used to move the conductive element 2 to switch between the first position and the second position. In the first state, the conductive element 2 can be in the first position, and the conductive element 2 turns on the first pin 11 and the second pin 12. When it is necessary to discharge the CMOS or clear the CMOS information, the driving element 3 moves the conductive element 2 to the second position, and the conductive element 2 turns on the second pin 12 and the third pin 13. After the operation is completed, the driving element 3 can move the conductive element 2 back to the first position. In other words, when the read / write chip needs to perform read / write operations, the driving element 3 only needs to move the conductive element 2 to the first position, and the conductive element 2 turns on the first pin 11 and the second pin 12, so that the read / write chip can perform read / write functions normally. When the read / write chip needs to perform an erase / clean operation, the driver 3 simply moves the conductive element 2 to the second position. The conductive element 2 then connects the second pin 12 and the third pin 13, allowing the read / write chip to perform the erase / clean function normally. The jumper device provided in this embodiment has a simple structure and is easy to operate. By moving the conductive element 2 with the driver 3, the CMOS clearing operation can be performed quickly and accurately, eliminating the cumbersome method of inserting and removing jumper caps required for CMOS clearing in the prior art. This facilitates user operation and prevents the jumper caps from being lost due to removal.

[0037] Optionally, the conductive component 2 can be sheet-like and made of a conductive material, specifically a metal. The driving component 3 can be made of an insulating material, specifically plastic. The first pin 11, the second pin 12, and the third pin 13 of the circuit board 1 can be three bare copper areas located on the circuit board 1.

[0038] In some specific embodiments, the driving component 3 is slidably engaged with the circuit board 1. The driving component 3 can slide relative to the circuit board 1. When the driving component 3 slides relative to the circuit board 1, the driving component 3 can drive the conductive component 2 to move, so that the conductive component 2 can switch between a first position and a second position, which is convenient for user operation.

[0039] In some specific embodiments, the circuit board 1 is provided with a guide hole 14, which extends along the direction from the first position to the second position; the driving member 3 includes a main body and a guide portion 32 connected to the main body, and the guide portion 32 is slidably disposed in the guide hole 14. When the direction from the first position to the second position is the first direction, the guide portion 32 can slide along the first direction, so that the driving member 3 can drive the conductive member 2 to move along the first direction, thereby switching the conductive member 2 between the first position and the second position, which is convenient for user operation.

[0040] Optionally, the guide portion 32 can be columnar or rod-shaped. Optionally, the guide portion 32 passes through the guide hole 14, which can improve the stability of the drive member 3 driving the conductive member 2 to move.

[0041] Combination Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, one of the main body and the guide part 32 is provided with a snap-fit ​​part 321, and the other of the main body and the guide part 32 is provided with a mating part 313a. The guide part 32 passes through the guide hole 14. The snap-fit ​​part 321 and the mating part 313a are snap-fitted or plugged into each other, so that the drive member 3 can be connected to the circuit board 1 and the drive member 3 is prevented from falling off the circuit board 1.

[0042] Optionally, one of the snap-fit ​​portion 321 and the mating portion 313a is a pin, and the other is a socket, with the pin engaging with the socket. Optionally, one of the snap-fit ​​portion 321 and the mating portion 313a is a protrusion, and the other is a groove, with the protrusion engaging with the groove. The snap-fit ​​or plug-in engagement of the snap-fit ​​portion 321 and the mating portion 313a offers the advantage of convenient installation and disassembly.

[0043] In some specific embodiments, the main body includes a first connecting portion 311, a second connecting portion 312, and a third connecting portion 313 connected sequentially. The first connecting portion 311 and the third connecting portion 313 are spaced apart and are located on opposite sides of the circuit board 1. Optionally, the circuit board 1 includes a first surface and a second surface. The first connecting portion 311 is disposed on the first surface, and the third connecting portion 313 is disposed on the second surface. This can improve the stability of the connection between the driving member 3 and the circuit board 1, as well as the stability of the driving member 3 when it drives the conductive member 2 to move relative to the circuit board 1. The guide portion 32 is disposed at the end of the first connecting portion 311 away from the second connecting portion 312. When the guide portion 32 has a snap-fit ​​portion 321, the mating portion 313a is disposed on the third connecting portion 313. When the guide portion 32 has a mating portion 313a, the snap-fit ​​portion 321 is disposed on the third connecting portion 313. This has the advantage of convenient installation and disassembly. Optionally, the first connecting portion 311, the second connecting portion 312, and the third connecting portion 313 are all plate-shaped, with a first bend between the first connecting portion 311 and the second connecting portion 312, and a second bend between the second connecting portion 312 and the third connecting portion 313. Optionally, the main body is generally U-shaped.

[0044] Optionally, the third connecting portion 313 is provided with a first balance arm 313b and a second balance arm 313c. Both the first balance arm 313b and the second balance arm 313c can be elastic, and both the first balance arm 313b and the second balance arm 313c abut against the surface of the circuit board 1. When the driving member 3 drives the conductive member 2 to move, the first balance arm 313b and the second balance arm 313c can maintain the balance of forces, improving the stability of the driving member 3 driving the conductive member 2 to move.

[0045] In some specific embodiments, the circuit board 1 is provided with a first limiting groove 15 and a second limiting groove 16, and the driving member 3 includes a limiting part 33. When the limiting part 33 is disposed in the first limiting groove 15, the conductive member 2 connects the first pin 11 and the second pin 12. When the limiting part 33 is disposed in the second limiting groove 16, the conductive member 2 connects the second pin 12 and the third pin 13. Optionally, the limiting part 33 can be a spring arm with a protruding structure at the end. Optionally, the limiting part 33 can be a lever. In use, moving the limiting part 33 causes the conductive member 2 to slide along a first direction, so that the conductive member 2 switches between a first position and a second position, completing the read / write or erase / clean operation of the chip.

[0046] In some specific embodiments, the driving component 3 is provided with a slot, and the conductive component 2 is disposed in the slot and engaged with the driving component 3, so that the driving component 3 can drive the conductive component 2 to switch between a first position and a second position. Optionally, the conductive component 2 and the driving component 3 can also be connected or bonded by fasteners.

[0047] In some specific embodiments, the conductive element 2 includes a first spring arm 21, which is used to abut against the first pin 11 and the second pin 12 in a first position, and against the second pin 12 and the third pin 13 in a second position. The first spring arm 21 is elastic and can generate a spring force toward the circuit board 1, which can improve the stability of the contact between the conductive element 2 and the first pin 11, the second pin 12 and the third pin 13.

[0048] In some specific embodiments, the conductive element 2 includes a second elastic arm 22, which abuts against the first elastic arm 21. The second elastic arm 22 is elastic, and the first elastic arm 21 can generate a force toward the circuit board 1 under the action of the elastic force of the second elastic arm 22, thereby improving the stability of the contact between the conductive element 2 and the first pin 11, the second pin 12, and the third pin 13.
