Because the annular bulge 2-6 just corresponds to the annular groove 1-2 in the inner cavity 1-1 and is in an interference compression state, the annular bulge 2-6 not only has the purposes of sealing and waterproofing, but also has the purpose of preventing the corner plug from accidentally falling off.
When the contact pin 9 and the positioning shaft 10 are fixed, in order to prevent the gap of the contact pin 9 caused by bending and pulling and pressing operations in the using process from leaking, the contact pin 9 and the positioning shaft 10 are fixed by adopting the contact pin fixing seat 13 made of the relatively hard sand foundation material, and a water-proof sealing body 11 made of the relatively soft polyurethane material is used for solving the possible water leakage link, so that the stability of the use and the sealing performance of the plug is better solved. Note that softer and harder are the degrees of softness of the pin holder 13 and the waterproof sealing body 11 compared with each other.
It should be noted that the injection molding material may be any other material that can be used in an injection molding process.
The above description is only for the preferred embodiments of the utility model and is not intended to limit the utility model, but various modifications and variations can be made by those skilled in the art.
