[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] In the description of this application, it should be noted that the terms "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] This application discloses a power connector.

[0030] Please refer to Figure 1 and Figure 2 In one embodiment of this application, a power connector includes a male connector 3 and a female connector 6. The male connector 3 contains a first power terminal 1, and the female connector 6 contains a second power terminal 4 corresponding to the first power terminal. The first power terminal 1 and the second power terminal 4 are inserted to connect an electronic product. The male connector 3 includes a male connector housing 9, and the first power terminal 1 is provided with a first claw 2, the outer wall of which abuts against the inner wall of the male connector housing 9. The female connector 6 includes a female connector housing 12, and the second power terminal 4 is provided with a second claw 5, the outer wall of which abuts against the inner wall of the female connector housing 12. During connector assembly, the first power terminal 1 and the second power terminal 4 are inserted. Under the interaction force, both the first power terminal 1 and the second power terminal 4 are subjected to opposing reaction forces and retract backward. Since the first claw 2 and the second claw 5 are respectively engaged between the first power terminal 1 and the male housing 9 and the second power terminal 4 and the female housing 12, the first power terminal 1 and the second power terminal 4 will be subject to resistance from the first claw 2 and the second claw 5 respectively when they are plugged in, thereby preventing the first power terminal 1 and the second power terminal 4 from retracting, so as to achieve a more ideal connection effect.

[0031] Specifically, such as Figure 1 and Figure 2As shown, the first claw buckle 2 includes a base 15 and a fastening part 16. The base 15 is an annular component, sleeved on the first power terminal 1, and the side annular surface of the base 15 has a hollow portion. One end of the fastening part 16 is connected to the radial side of the hollow portion away from the connection between the first power terminal 1 and the second power terminal 4, and the other end extends in the direction toward the connection between the first power terminal 1 and the second power terminal 4 and abuts against the first power terminal 1. When the first power terminal 1 retracts, the base 15 is subjected to frictional force from the receiving hole, which exerts resistance on the first power terminal 1; at the same time, the fastening part 16 abutting against the first power terminal 1 also exerts resistance on it. Through the combined action of the base 15 and the fastening part 16, the first power terminal 1 can be effectively prevented from retracting during insertion, ensuring the connection effect. In the embodiment shown in Figure 1, the second claw buckle 5 has the same shape as the first claw buckle 2. Furthermore, there can be multiple hollow portions and corresponding fastening parts 16. In the embodiment shown in Figure 1, there are three hollowed-out portions and corresponding fastening portions 16, evenly distributed around the power terminal. Compared to the case with only one fastening portion 16, multiple fastening portions 16 can better distribute the pressure from the power terminal. Furthermore, the fastening portion 16 can be an elastic component. When the fastening portion 16 is subjected to pressure, it generates elastic potential energy. When the power terminal retracts a certain distance, the fastening portion 16 releases the elastic potential energy to push the power terminal back to its original position, further ensuring the connection between the power terminals and avoiding poor contact that could affect the normal use of the electrical appliance.

[0032] like Figure 1 and Figure 2 As shown, in an optional embodiment of this application, the first power terminal 1 is provided with a pair of annular protrusions 17, and the base 15 of the first claw buckle 2 is fitted onto the pair of annular protrusions 17. A groove is formed between the pair of annular protrusions 17 and the first power terminal 1, and the fastening part 16 of the first claw buckle 2 extends into the groove and abuts against the first power terminal 1. Correspondingly, the second power terminal 4 is provided with the same pair of annular protrusions 17, and the base 15 of the second claw buckle 5 is fitted onto the pair of annular protrusions 17. A groove is formed between the pair of annular protrusions 17 and the second power terminal 4, and the fastening part 16 of the second claw buckle 5 extends into the groove and abuts against the second power terminal 4. With this arrangement, the inclination of the fastening part 16 can be increased. The higher the inclination, the greater the resistance received by the power terminal when it retracts, according to the principle of mechanics, further strengthening the obstructive effect of the first claw buckle 2 and the second claw buckle 5.

[0033] Furthermore, the male connector 3 includes a male connector housing 9, which has a first receiving hole 7 for receiving the first power terminal 1. A retaining platform is provided within the first receiving hole 7, and a first claw 2 engages with this retaining platform. Correspondingly, the female connector 6 includes a female connector housing 12, which has a second receiving hole 13 for receiving the second power terminal 4. The second receiving hole 13 has the same retaining platform, and a second claw 5 engages with this retaining platform. The retaining platform limits the movement of the first power terminal 1 and the second power terminal 4, further preventing them from retracting and ensuring a proper connection between them.

[0034] It should be noted that the number of power terminals can be changed according to actual needs; that is, the power connector provided in this application can be a single-pole connector, a three-pole connector, or other multi-pole connector. Figure 1 In one embodiment shown, there are four first power terminals 1, spaced apart and each disposed within one of four first receiving holes 7. If all four power terminals are housed in a single receiving hole, they may squeeze and rub against each other, causing damage or wear. By distributing the four power terminals into four separate receiving holes, squeezing and friction between them is avoided, providing stronger protection for each terminal. This arrangement also serves as a limiting mechanism, ensuring precise mating of the first power terminals 1 and the second power terminals 4.

[0035] In an optional embodiment of this application, the male connector 3 is further provided with a first connector liner 8, located at the rear end of the male connector housing 9 away from the connection point of the first power terminal 1 and the second power terminal 4. Correspondingly, the female connector 6 is further provided with a second connector liner 14, located at the rear end of the female connector housing 12 away from the connection point of the first power terminal 1 and the second power terminal 4, with the second receiving hole 13 penetrating through the second connector liner 14. The first connector liner 8 and the second connector liner 14 can protect the internal first power terminal 1 and the second power terminal 4, preventing damage to the first power terminal 1 and the second power terminal 4, thereby affecting the connector's connection function. Simultaneously, since the rear end of the housing is relatively thin, the connector liner can also provide better support for the housing, allowing the user to apply more force during insertion. Preferably, the first connector liner 8 and the second connector liner 14 can be made of materials with relatively higher hardness, while the male connector housing 9 and the female connector housing 12 can be made of materials with relatively better insulation. Furthermore, to facilitate the connection between the first power terminal 1 and the second power terminal 4, the first receiving hole 7 passes through the first connector inner liner 8 and the male head housing 9, and the second receiving hole 13 passes through the second connector inner liner 14 and the female head housing 12.

[0036] Furthermore, a loose gap can be left between the post of the first power terminal 1 and the first receiving hole 7; correspondingly, a loose gap is also left between the post of the second power terminal 4 and the second receiving hole 13. This is to prevent insufficient precision of the mold and to serve a calibration function.

[0037] In an optional embodiment of this application, the male connector housing 9 has a plug portion 10 at its front end near the connection point of the first power terminal 1 and the second power terminal 4. Correspondingly, the female connector housing 12 has a insertion groove 11 at its front end near the connection point of the first power terminal 1 and the second power terminal 4. The plug portion 10 is inserted into the insertion groove 11 to achieve the connection between the male connector 3 and the female connector 6. With the above arrangement, when the male connector 3 and the female connector 6 are plugged in, a closed space is formed at the connection point, which can achieve the effect of waterproofing and dustproofing, preventing rainwater and dust from contacting the power terminals and affecting the normal use of the connector. This also further expands the application range of the power connector and improves its own use value.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
