[0028] like Figures 1 to 5 As shown, an embodiment of the present invention provides a socket housing assembly, including a socket housing 1, a sealing ring 5, and an end cap 4. One end of the socket housing 1 is provided with a slot 2. The slot 2 has an opening along the insertion direction of the socket housing 1. A plug-in part 3 protruding towards the opening is connected to the bottom wall of the slot of the slot 2. The plug-in part 3 is located inside the slot 2. An insertion gap is formed between the outer peripheral surface of the plug-in part 3 and the side wall of the slot of the slot 2. The insertion gap is used for the plug housing of the plug to be inserted. The sealing ring 5 is sleeved on the plug-in part 3. The end cap 4 is sleeved on the end of the plug-in part 3 away from the bottom wall of the slot of the slot 2.

[0029] The end cap 4 is detachably connected to the insertion part 3 so that the sealing ring 5 is pressed between the side of the end cap 4 near the bottom wall of the slot 2 and the bottom wall of the slot 2 along the insertion direction of the socket housing 1.

[0030] In this embodiment, the sealing ring 5 is sleeved on the plug-in part 3. The sealing ring 5 is located between the end cover 4 and the bottom wall of the slot 2. The end cover 4 and the plug-in part 3 are detachably connected and can be clamped between the end cover 4 and the bottom wall of the slot 2, thereby limiting the sealing ring 5 along the plugging direction of the socket housing 1, preventing the sealing ring 5 from falling off when the socket housing 1 and the plug are plugged in and out, and improving the stability of the sealing ring 5.

[0031] In one embodiment, the end cap 4 includes a covering portion 7 and a stop portion 11, which are perpendicular to each other. The covering portion 7 is sleeved on the outer peripheral surface of the insertion portion 3, and the stop portion 11 contacts one side of the insertion portion 3 away from the bottom wall of the slot 2.

[0032] In this embodiment, the covering portion 7 and the blocking portion 11 are perpendicular to each other.

[0033] In this embodiment, the end cap 4 is divided into a stop portion 11 and a covering portion 7, which can be better fitted onto the plug portion 3, increasing the contact area between the end cap 4 and the plug portion 3, and improving the protection between the end cap 4 and the plug portion 3. The stop portion 11 can also limit the covering portion 7 in the plugging direction of the socket housing 1.

[0034] In one embodiment, the sealing ring 5 is provided with a first locking structure 16, and the end cap 4 is provided with a second locking structure 13. The first locking structure 16 and the second locking structure 13 cooperate to lock the sealing ring 5 between the end cap 4 and the slot 2.

[0035] In this embodiment, the first locking structure 16 and the second locking structure 13 lock together, which can limit the sealing ring 5 between the end cover 4 and the bottom wall of the slot 2. This improves the stability of the end cover 4 and prevents the end cover 4 from falling off the insertion part 3.

[0036] In one embodiment, the first locking structure 16 includes a first snap-fit ​​plate 17, which is disposed on the side of the sealing ring 5 facing away from the bottom wall of the slot 2, and the first snap-fit ​​plate 17 is provided with a first snap-fit ​​hole 18.

[0037] The second locking structure 13 includes a first locking block 14 protruding on the inner circumferential surface of the covering part 7, and the first locking block 14 engages with the first locking hole 18.

[0038] In this embodiment, the first snap-fit ​​plate 17 is disposed on the end face of the sealing ring 5 near the end cap 4.

[0039] In this embodiment, the first snap-fit ​​block 14 is disposed on the inner peripheral surface of the covering portion 7, and the first snap-fit ​​block 14 protrudes toward the outer peripheral surface of the insertion portion 3.

[0040] In this embodiment, the first locking structure 16 and the second locking structure 13 are engaged by the first snap-fit ​​block 14 and the first snap-fit ​​hole 18, which is simple in structure and easy to design.

[0041] In one embodiment, the side of the first snap-fit ​​block 14 facing the sealing ring 5 is an inclined surface 15, and the distance between the upper end of the inclined surface 15 and the insertion part 3 is less than the distance between the lower end of the inclined surface 15 and the insertion part 3.

[0042] In this embodiment, one side of the first snap-fit ​​block 14 facing the outer peripheral surface of the insertion part 3 is an inclined surface 15.

[0043] In this embodiment, the inclined surface 15 is provided so that when the end cap 4 is sleeved on the insertion part 3, the inclined surface 15 can guide the first snap plate 17, making it easier for the first snap block 14 to snap into the first snap hole 18.

[0044] In one embodiment, the stop portion 11 of the end cap 4 is provided with a clearance hole 12, and the first snap-fit ​​plate 17 is inserted into the clearance hole 12.

[0045] In this embodiment, a clearance hole 12 is provided at the position where the stop part 11 contacts the cover, and the clearance hole extends through the stop part 11 along the length direction of the insertion part 3.

[0046] In this embodiment, the end of the first snap-fit ​​plate 17 away from the sealing ring 5 can be inserted into the clearance hole 12.

[0047] In this embodiment, the clearance hole 12 is positioned at the end of the first snap-fit ​​plate 17 furthest from the sealing ring 5 to provide installation space. This facilitates the snap-fit ​​of the first snap-fit ​​block 14 with the first snap-fit ​​hole 18.

[0048] In one embodiment, a second snap-fit ​​hole 6 is provided on the outer peripheral surface of the insertion part 3.

[0049] A second snap-fit ​​block 10 is provided on the inner circumferential surface of the covering part 7, and the second snap-fit ​​block 10 is engaged with the second snap-fit ​​hole 6.

[0050] In this embodiment, the second snap-fit ​​hole 6 is provided on the outer peripheral surface of the plug-in part 3, which means that the plug-in part 3 is provided with a second snap-fit ​​hole 6 that penetrates the plug-in part 3 along its own thickness direction.

[0051] In this embodiment, the second snap-fit ​​block 10 is provided on the inner peripheral surface of the covering part 7, which means that the second snap-fit ​​block 10 is provided on the inner peripheral surface of the covering part 7, and the second snap-fit ​​block 10 protrudes towards the inner peripheral surface of the insertion part 3.

[0052] In this embodiment, the second snap-fit ​​block 10 engages with the second snap-fit ​​hole 6 to achieve a detachable connection between the end cap 4 and the plug-in part 3. The structure is simple and easy to assemble and disassemble.

[0053] In one embodiment, the covering part 7 is provided with a notch 8, and an elastic arm 9 is provided in the notch 8. One end of the elastic arm 9 is connected to the stop part 11, and the second locking block 10 is provided at the other end of the elastic arm 9.

[0054] In this embodiment, the opening of the notch 8 faces the sealing ring 5.

[0055] In this embodiment, the elastic arm 9 is disposed on the side wall of the notch groove 8 facing the sealing ring 5.

[0056] In this embodiment, the second snap-fit ​​block 10 is disposed at one end of the elastic arm 9 near the sealing ring 5, which facilitates manufacturing.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] According to the socket housing assembly provided in this embodiment of the present utility model, the sealing ring 5 is sleeved on the plug-in part 3. The sealing ring 5 is located between the end cover 4 and the bottom wall of the slot 2. The end cover 4 and the plug-in part 3 are detachably connected and can be clamped between the end cover 4 and the bottom wall of the slot 2, thereby limiting the sealing ring 5 along the plugging direction of the socket housing 1, preventing the sealing ring 5 from falling off when the socket housing 1 and the plug are plugged in and out, and improving the stability of the sealing ring 5.

[0059] In addition, one embodiment of the present invention also provides a socket, including a socket terminal and the above-mentioned socket housing assembly, wherein the socket terminal is installed in the socket housing 1, and one end of the socket terminal is exposed in the plug portion 3.
