Detailed Implementation

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] Contents not described in detail in this specification are existing technologies known to those skilled in the art. In the description of this utility model, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They 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 limiting this utility model. Furthermore, terms such as "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Example 1:

[0033] like Figures 1 to 3 As shown, this embodiment provides a power connector housing, including an insulating housing 1, an elastic locking arm 2, and a limiting member 3. The elastic locking arm 2 is fixed to the top of the insulating housing 1, and the elastic locking arm 2 has a free end. The limiting member 3 is disposed on the insulating housing 1 and has a limiting end for restricting the free end from moving away from the insulating housing 1. By setting the limiting member 3, the elastic locking arm 2 is limited, preventing its free end from being excessively bent, causing deformation or breakage, when it is not mated with the mating connector 5.

[0034] The limiting member 3 includes a vertical part 31 and a horizontal part 32. The vertical part 31 is fixed to the top of the insulating housing 1, and the horizontal part 32 is fixed to the top of the vertical part 31. The vertical part 31 is located outside the free end of the elastic locking arm 2, and the horizontal part 32 is located above the free end of the elastic locking arm 2. The horizontal part 32 limits the upward deformation distance of the free end, and the vertical part 31 limits the left and right swing distance of the free end, thus ensuring the lifespan of the elastic locking arm 2.

[0035] The limiting member 3 further comprises a reinforcing rib 33, which is arranged between the upright portion 31 and the top of the insulating shell 1. The reinforcing rib 33 improves the strength of the limiting member 3, effectively disperses stress and reduces stress concentration, thereby preventing the limiting member 3 from being damaged when subjected to external force, and further ensuring the limiting of the elastic locking arm 2.

[0036] The elastic locking arm 2 comprises a fixed portion 21, a bent portion 22, an extension portion 23, and a pressing portion 24. The fixed portion 21 is fixed to the top of the insulating shell 1. The fixed portion 21 and the extension portion 23 are connected by the bent portion 22. The front end of the extension portion 23 is fixed with the pressing portion 24. The left and right side walls of the pressing portion 24 are each provided with a protruding portion 25, which is located below the horizontal portion 32 and inside the upright portion 31. There are two limiting members 3, which are arranged on the left and right sides of the pressing portion 24. The extension portion 23 is arranged upwardly inclined. The fixed portion 21, the bent portion 22, the extension portion 23, and the pressing portion 24 form a structure of the elastic locking arm 2, which is fixed at one end to the insulating shell 1 and is freely pressable and resettable at the other end. The protruding portion 25 cooperates with the limiting member 3 from the side, without occupying the pressing surface of the pressing portion 24.

[0037] The top of the extension portion 23 is fixed with a clamping block 26. The clamping block 26 cooperates with the clamping groove on the mating connector 5 to achieve locking. When unlocking, the pressing portion 24 is pressed downward, causing the extension portion 23 to tilt downward and driving the clamping block 26 to move downward away from the clamping groove, and then the power connector can be pulled out.

[0038] The clamping block 26 and the pressing portion 24 form a limiting space 27. The limiting space 27 limits the mating and avoids excessive mating of the power connector.

[0039] Embodiment Two:

[0040] As shown in Figure 4 , the embodiment provides a power connector, which comprises a power terminal 4 and the power connector shell of embodiment one. The power connector shell is internally fixed with a plurality of power terminals 4.

[0041] Embodiment Three:

[0042] As shown in Figure 5 , the embodiment provides a connector assembly, which comprises the power connector of embodiment two and a mating connector 5 that mates with the power connector.

[0043] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
