Furthermore, the plastic package body is provided with an installation end at one end close to the insulator, and the installation ends at the upper side and the lower side of the insulator are respectively provided with a guide post matched with the jack of the opposite plug-in connector.

Furthermore, the front end of the guide post is provided with a conical guide surface.

Furthermore, floating screws are respectively arranged on the mounting ends of the upper side and the lower side of the insulator.

Furthermore, the outer contour of the insulator and the guide posts arranged at the mounting ends of the upper side and the lower side of the insulator are in central symmetry structures, and the terminals are uniformly and symmetrically arranged up and down.

Compared with the prior art, the utility model beneficial effect who has is:

1. the utility model discloses novel structure, the practicality is strong. The utility model discloses a connector pencil subassembly is easy and simple to handle, can float, to inserting to realize functions such as comprehensive waterproof after connecting, simple structure, the cost is lower, and in use manual efficiency is showing and is promoting. The utility model discloses a floating screw and guide post have solved the module and have relatively poor and the inserting that leads to of in-process positioning accuracy close not last problem, owing to set up floating screw and guide post, consequently require lowerly to the positioning accuracy of whole module.

2. The utility model discloses a pencil subassembly inserts at the connector and closes the in-process, realizes radial waterproof sealing through wherein sealing washer and butt joint end connector, and the plastic-sealed body lives terminal and cable and insulator parcel, forms sealedly.

3. The utility model discloses an appearance and the guide post of insulator adopt central symmetry structure, and the terminal is the symmetrical arrangement of upper and lower homonymy, realizes positive and negative rotation 180 and also can accomplish the butt joint of electrical function equally to inserting.
