Description

Technical Field

[0001] This utility model relates to the field of power cords, and more particularly to a graphics card power cord and a power supply for the aforementioned graphics card power cord. Background Technology

[0002] The 12V HPWR power supply is a new type of high-power graphics card power cable in recent years. This type of power cable is prone to improper assembly, and prolonged operation can easily cause the terminal temperature to rise. To address this, the new 12V HPWR power supply has shortened the SENSE signal pin, but it is still difficult to prevent the terminal temperature of the 12V HPWR power supply from rising, which can cause the plastic parts to melt and cause irreversible damage to the graphics card or power supply.

[0003] Chinese patent document CN117353113A discloses an AC power cord for a communication device, including a cord body and male and female plugs at both ends of the cord body. The male plug includes a live wire guide, a neutral wire guide, and a ground wire guide. The female plug has conductive tabs corresponding to the live, neutral, and ground wires. The male plug contains an overcurrent protector. Correspondingly, the protective shell of the male plug has a slot for inserting the overcurrent protector. The overcurrent protector deforms a bimetallic strip by heating an internal thermistor, causing the conductive tabs to disconnect from the first and second conductive tabs. The cord body has inner and outer insulation layers, and both the inner and outer insulation layers have flame-retardant layers on the outside to improve the high-temperature resistance of the cord. Existing AC power cords, which deform the bimetallic strip by heating an internal thermistor in the overcurrent protector, are clearly unsuitable for installation in the relatively small power cords of graphics cards. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a graphics card power cable. By reasonably setting the installation position of the thermistor, the overheating phenomenon of the graphics card power cable can be effectively detected while ensuring that the size of the graphics card power cable interface is small enough, so as to avoid the cable assembly from burning out due to temperature rise.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a graphics card power cable, including a main interface and a sensing interface. The sensing interface is fixed above the main interface and includes a sensing plug and a sensing wire. The sensing plug is connected to the sensing wire. The number of first PIN ports on the sensing plug is less than the number of first type wire ports in the sensing wire. At least one side of the sensing wire is provided with a thermistor, and the thermistor is electrically connected to a first type cable inserted into the first type wire port.

[0007] The preferred technical solution of this utility model is that thermistors are provided on both sides of the sensing wiring part, the number of first PIN ports on the sensing plug part is 4, the number of first type wire plugs in the sensing wiring part is 6, and two thermistors are respectively arranged in the first first type wire plug and the sixth first type wire plug.

[0008] A preferred embodiment of this utility model is that the main interface includes a main plug-in part and a main wiring part, the main plug-in part is connected to the main wiring part, the second PIN port on the main plug-in part corresponds to the second type of wire plug on the main wiring part, and the number of the second PIN port and the number of the second type of wire plug are equal.

[0009] The preferred technical solution of this utility model is that the number of the second PIN port and the number of the second type of cable connector are both 12.

[0010] A preferred embodiment of this invention is that the upper surface of the sensing wiring portion is provided with a guide convex surface.

[0011] A preferred embodiment of this invention is that the guide surface includes a guide surface and an isolation surface, the guide surface being located on one side of the isolation surface and close to the sensing connector.

[0012] A preferred embodiment of this invention is that one side of the guide surface is connected to the isolation surface, and the other side of the guide surface is provided with a wedge-shaped surface for easy insertion.

[0013] A preferred embodiment of this invention is that a first type of baffle is provided at the edge of the sensing wiring portion.

[0014] A preferred embodiment of this invention is that inclined walls are provided on both sides of the sensing wiring portion.

[0015] This utility model also provides a power supply, including the aforementioned graphics card power cable and power supply body. The graphics card power cable is electrically connected to the power supply body. A PCB control board is disposed inside the power supply body. The PCB control board is electrically connected to the thermistor through the first type of cable.

[0016] The beneficial effects of this utility model are as follows:

[0017] The graphics card power cable provided by this utility model increases the number of first-type wire connectors in the sensing connector section, making the number of first-type wire connectors greater than the number of first PIN ports on the sensing connector section. This ensures that at least one more first-type wire connector is reasonably provided without affecting the original structure and function of the graphics card power cable. This connector is used to connect the first-type cable to a thermistor, thereby obtaining the detection signal from the thermistor and enabling the graphics card power cable to have a temperature detection function, thus preventing the cable assembly from overheating and burning out.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figures 1 to 4As shown, the graphics card power cable provided in this embodiment is a 12V HPWR cable. The graphics card power cable includes a main interface 1 and a sensing interface 2. The sensing interface 2 is fixed above the main interface 1. The main interface 1 has 12 second PIN ports 111 for providing power and signal transmission. The sensing interface 2 is used to detect the SENCE signal and determine the working mode of the graphics card power supply through the SENCE signal. The sensing interface 2 includes a sensing plug part 21 and a sensing wire part 22. The sensing plug part 21 is connected to the sensing wire part 22. Specifically, the sensing plug part 21 and the sensing wire part 22 are integrally formed. The first P on the sensing plug part 21 The number of IN ports 211 is less than the number of first-type wire connectors 221 in the sensing connector 22. The extra first-type wire connectors 221 on the sensing connector 21 can be used to install the thermistor 3 and insert the first-type cable 41. That is, the thermistor 3 can be installed in the first-type wire connector 221 and close to the heat source concentration position on the main interface 1. Preferably, the thermistor 3 is provided on at least one side of the sensing connector 22. The thermistor 3 is electrically connected to the first-type cable 41 inserted into the first-type wire connector 221, so as to detect the temperature change at the heat source concentration position. By increasing the number of first-type cable connectors 221 in the sensing connector section 22, and ensuring that the number of first-type cable connectors 221 is greater than the number of first PIN ports 211 on the sensing connector section 21, at least one more first-type cable connector 221 is reasonably provided without affecting the original structure and function of the graphics card power cable. This connector can be used to connect the first-type cable 41 to the thermistor 3, thereby obtaining the detection signal of the thermistor 3, enabling the graphics card power cable to have a temperature detection function and preventing its cable assembly from overheating and burning out.

[0027] To facilitate the detection of temperature changes at the concentrated heat source locations on both sides of the main interface 1, thermistors 3 are further provided on both sides of the sensing connector 22. The sensing connector 21 has four first PIN ports 211, and the sensing connector 22 has six first-type wire connectors 221. Two thermistors 3 are respectively located in the first and sixth first-type wire connectors 221. Therefore, compared to the traditional 12V HPWR cable, the graphics card power cable provided in this embodiment has two thermistors symmetrically arranged, which can effectively detect temperature changes at the concentrated heat source locations of the main interface 1.

[0028] The main interface 1 includes a main connector 11 and a main connector 12. The main connector 11 is connected to the main connector 12. The second PIN port 111 on the main connector 11 corresponds to the second type cable connector 121 on the main connector 12. The number of second PIN ports 111 and second type cable connectors 121 are equal. After the second type cable 42 is inserted into the second type cable connector 121, it is electrically connected to the PIN pin of the second PIN port 111. Preferably, the number of second PIN ports 111 and second type cable connectors 121 are both 12. The graphics card power cable provided in this application is very suitable for 12VHPWR cable groups, and of course, it can also be applied to other power cables that include the main interface 1 and the sensing interface 2.

[0029] To facilitate the insertion of a portion of the sensing connector 22 into the power interface, a guide protrusion 222 is further provided on the upper surface of the sensing connector 22, which allows the sensing connector 22 to be inserted into the power interface more smoothly. More preferably, the guide surface 222 includes a guide surface 2221 and an isolation surface 2222. The guide surface 2221 is located on one side of the isolation surface 2222 and close to the sensing plug-in part 21. One side of the guide surface 2221 is connected to the isolation surface 2222. The other side of the guide surface 2221 is provided with a wedge-shaped surface 2223 to facilitate insertion. When a part of the sensing connector 22 is inserted into the power interface, the guide surface 2221 can smoothly enter the power interface under the guidance of the wedge-shaped surface 2223. Then the isolation surface 2222 will be higher than the upper surface of the sensing plug-in part 21. This will reduce or even avoid friction on the sensing plug-in part 21 during the insertion process, thereby protecting the sensing plug-in part 21 while also providing a suitable interference force.

[0030] A first type of baffle 223 is provided at the edge of the sensing connector 22, and a second type of baffle 122 is provided on both sides of the main connector 12. The first type of baffle 223 and the second type of baffle 122 can limit the distance that the sensing connector 22 and the main connector 12 can be inserted into the power interface, that is, the insertion depth of the graphics card power cable connector. In addition, sloping walls 224 are provided on both sides of the sensing connector 22. The sloping walls 224 facilitate the insertion and mating of the sensing connector 22 and the power interface, reduce the resistance during the insertion process, and improve the stability of the insertion.

[0031] Example 2

[0032] The power supply provided in this embodiment includes the aforementioned graphics card power cable and power supply body. The graphics card power cable is electrically connected to the power supply body. A PCB control board is disposed inside the power supply body. The PCB control board is electrically connected to the thermistor 3 through a first type of cable. The thermistor 3 can transmit the detection signal to the PCB control board. When the PCB control board detects an abnormal temperature at the interface of the graphics card power cable, it issues a control command to cut off the power supply in time.
