Description

Technical Field

[0001] This utility model relates to a power adapter cable, specifically a 12P power adapter cable. Background Technology

[0002] A 12-pin power adapter cable is a special cable used to connect high-performance graphics cards to the power supply, primarily for adapting to the 12-pin auxiliary power connector of NVIDIA RTX 30 series graphics cards. This adapter cable can convert traditional 8-pin or dual 8-pin power connectors to 12-pin connectors to meet the high power requirements of graphics cards.

[0003] The existing 12-pin power adapter cable has a relatively complex structure and an unreasonable design. When in use, the female end of the 12-pin power adapter cable is plugged into the graphics card, and then the cable is left to hang naturally inside the computer case, causing it to bend. However, the existing 12-pin power adapter cable lacks an internal structure to protect the terminals, making them prone to burnout after bending, thus shortening its lifespan. Furthermore, the 12-pin power adapter cable is subjected to gravity and bending over time, and given its inherent rigidity, repeated bending can easily cause irreversible deformation, leading to malfunction. Therefore, the inventor has improved the structure of the 12-pin power adapter cable. Utility Model Content

[0004] The purpose of this utility model is to provide a 12P power adapter cable with a simple structure and reasonable design. The multiple sleeves can protect the internal terminals that need to be bent, preventing the internal terminals from burning out due to excessive bending, thus improving safety and extending life. The terminal body can withstand bending without being damaged by bending, which helps to improve the yield rate. It also has the advantage of maintaining a certain degree of flexibility after repeated bending, thus solving the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 12P power adapter cable, which includes a cable body and female connectors and male connectors respectively connected to both ends of the cable body. The male connector includes a first male connector and a second male connector located on one side of the first male connector. The cable body includes a velvet protective sleeve, which is a hollow cavity structure with openings at both ends. Multiple sleeves and internal terminals respectively fixed inside the multiple sleeves are provided inside the cavity. The internal terminals include terminal bodies provided inside the sleeves and plastic tubes and flexible tubes sleeved on the terminal bodies. Multiple plastic tubes and flexible tubes are provided, and the plastic tubes and flexible tubes are arranged crosswise.

[0006] Preferably, the cross-section of the wire body is circular, and the diameter of the circle is between 13mm and 18mm.

[0007] Preferably, multiple sleeves are spaced apart, and adjacent sleeves are fixedly bonded together.

[0008] Preferably, adjacent plastic tubes and hoses are fixedly connected, and the whole consisting of multiple plastic tubes and multiple hoses is hollow, with the terminal body passing through the whole consisting of multiple plastic tubes and multiple hoses.

[0009] Preferably, the plastic tubes and hoses are both bonded and fixed to the inner wall of the sleeve, and the terminal bodies are respectively fixed inside the multiple plastic tubes and multiple hoses, so that the terminal bodies, plastic tubes and hoses can remain stationary inside the sleeve.

[0010] Preferably, the female connector includes a female housing and a female terminal disposed on the female housing, the female terminal being connected to a plurality of internal terminals.

[0011] Preferably, the first male connector includes a first proximal wire and a first male housing and a first velvet wire divider connected to both ends of the first proximal wire, with the end of the first velvet wire divider away from the first proximal wire connected to a portion of the internal terminals. The second male connector includes a second proximal wire and a second male housing and a second velvet wire divider connected to both ends of the second proximal wire, with the end of the second velvet wire divider away from the second proximal wire connected to another portion of the internal terminals.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a 12P power adapter cable. The 12P power adapter cable includes a main body 1 and female connectors and male connectors respectively connected to both ends of the main body. The male connectors include a first male connector and a second male connector located on one side of the first male connector. The overall structure is simple and reasonably designed. The main body of the cable includes a velvet protective sleeve, which is a hollow cavity structure with openings at both ends. Multiple sleeves and internal terminals fixed inside the multiple sleeves are arranged inside the cavity. By wrapping a sleeve around the outside of each internal terminal inside the velvet protective sleeve, the internal terminals are well protected. When the female terminal is inserted into the graphics card, the position of the velvet protective sleeve will naturally droop under the action of gravity and need to be bent to a certain extent inside the computer case. Multiple sleeves can protect multiple internal terminals that need to be bent, avoiding the internal terminals from burning out due to excessive bending, improving safety and extending life, and is suitable for widespread use.

[0014] 2. The internal terminal of this utility model includes a terminal body disposed inside the sleeve and a plastic tube and a flexible tube sleeved on the terminal body. Multiple plastic tubes and flexible tubes are provided, and they are arranged in a crisscross pattern. By crisscrossing the plastic tubes and flexible tubes, and by ensuring that the hardness of the plastic tubes is greater than that of the flexible tubes, a portion of the surface of the terminal body remains a harder material, while another portion remains a softer material. This allows the terminal body to withstand bending without being damaged by bending, which helps to improve the yield rate. Even after repeated bending, it can still maintain a certain degree of flexibility, without irreversible deformation, and can still be used normally, making it highly practical.

[0023] Please see Figure 1 The present invention provides an embodiment of a 12P power adapter cable, which includes a cable body 1 and a female connector 2 and a male connector respectively connected to both ends of the cable body 1. The male connector includes a first male connector 3 and a second male connector 4 located on one side of the first male connector 3. The cross-section of the cable body 1 is circular, and the diameter of the circle is between 13mm and 18mm.

[0024] Please see Figure 2The female connector 2 includes a female housing 21 and female terminals 22 disposed on the female housing 21. The female terminals 22 are connected to multiple internal terminals 13. The first male connector 3 includes a first proximal wire 32 and a first male housing 31 and a first velvet wire divider 33 respectively connected to both ends of the first proximal wire 32. The end of the first velvet wire divider 33 away from the first proximal wire 32 is connected to a portion of the internal terminals 13. The second male connector 4 includes a second proximal wire 42 and a second male housing 41 and a second velvet wire divider 43 respectively connected to both ends of the second proximal wire 42.

The structure of the second male connector 4 is basically the same as that of the first male connector 3, except that the first male housing 31 is an EL-1*3P white male housing, and the terminals disposed inside the first male housing 31 are EL tin-plated female terminals. The second male housing 41 is a DJ7031A-2.8-11. The 3P natural color female shell is made of PA6+GF10 material, and the terminals inside the second male shell 41 are DJ611-2.8*0.5A plated tin terminals.

[0025] Please see Figure 3 The main body 1 of the cable includes a velvet protective sleeve 11, which is a hollow cavity structure with openings at both ends. Multiple sleeves 12 and internal terminals 13 fixed inside the multiple sleeves 12 are arranged in the cavity. The multiple sleeves 12 are spaced apart, and adjacent sleeves 12 are fixedly bonded together. When the female terminal 22 is inserted into the graphics card, the position of the velvet protective sleeve 11 will naturally droop under the action of gravity and needs to be bent to a certain extent inside the computer case. The multiple sleeves 12 can protect the multiple internal terminals 13 that need to be bent, so as to prevent the internal terminals 13 from being burned out due to excessive bending, thereby improving safety and extending life.

[0026] Please see Figure 4The internal terminal 13 includes a terminal body 131 disposed inside the sleeve 12, and plastic tubes 132 and flexible tubes 133 sleeved on the terminal body 131.

The terminal body 131 penetrates the entire structure formed by the multiple plastic tubes 132 and multiple flexible tubes 133. The hardness of the plastic tubes 132 is greater than that of the flexible tubes 133, so that a portion of the surface of the terminal body 131 remains made of a harder material. The other part is made of a softer material, so that the terminal body 131 can withstand bending without being damaged by bending, which helps to improve the yield rate. After repeated bending, it can still maintain a certain degree of flexibility, without irreversible deformation, and can be used normally. In this embodiment, the plastic tube 132 is made of TPU and the flexible tube 133 is made of rubber. The plastic tube 132 and the flexible tube 133 are both bonded and fixed to the inner wall of the sleeve 12.
