The integrated adapter sleeve is sequentially divided into a mounting portion, a guide portion and a connecting portion. The plug assembly is threadedly connected to the mounting portion. The cable compression cap is sleeved on the connecting portion and is threadedly connected to the connecting portion. In the direction from the mounting portion to the connecting portion, the hole diameter of the guide portion gradually decreases.

[0008] Further, a limiting groove is formed at the opening of the connecting portion. A rubber ring is arranged in the limiting groove.

[0009] Further, the plug assembly comprises a socket shell, a jack cover plate, a jack insulator and a plurality of jack pieces. The socket shell is threadedly connected on the integrated adapter sleeve. The jack cover plate and the jack insulator are sequentially fixed in the inner cavity of the socket shell. A plurality of first plug-in holes and second plug-in holes are respectively formed on the jack cover plate and the jack insulator. The first plug-in holes and the second plug-in holes are correspondingly communicated with each other to form jack channels. The jack pieces are respectively inserted and fixed in the jack channels.

[0010] Further, an installation notch is formed on the inner wall of the socket shell. A grounding ring is arranged in the installation notch. The inner ring of the grounding ring abuts against the jack cover plate.

[0011] Further, a stepped surface is arranged between the inner cavity of the installation portion and the inner cavity of the guide portion. A sealing ring is arranged on the stepped surface. The inner end of the socket shell abuts against the sealing ring.

[0012] Further, the outer ring of the socket shell is provided with a connecting nut. An O-ring is arranged between the connecting nut and the socket shell.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] The utility model discloses a plug assembly which comprises an integrated adapter sleeve, and the inner cavity of the integrated adapter sleeve is sequentially divided into an installation portion, a guide portion and a connecting portion. In the direction from the installation portion to the connecting portion, the hole diameter of the guide portion gradually decreases, so that the cable on the plug assembly can be guided and restrained through the guide portion, the installation of the cable on the plug assembly is facilitated, and the added plastic wire fixing claw is removed, thereby saving the production cost.

DETAILED DESCRIPTION

[0018] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a low-cost plastic-cased sealed socket includes a plug assembly 1, an integrated adapter sleeve 2, and a cable clamping cap 3. The integrated adapter sleeve 2 is sequentially divided into a mounting portion 2-1, a guide portion 2-2, and a connecting portion 2-3. The plug assembly 1 is threaded onto the mounting portion 2-1. The cable clamping cap 3 is fitted onto the connecting portion 2-3 and threadedly connected to it.
