The sleeve can be made into a structure which is slightly longer than the connecting part, waterproof glue can be injected from the rear part of the sleeve, and the sheath is sleeved on the sleeve. Because the sleeve pipe is a lot of less than the sheath, the rear end of sleeve pipe is very close to connecting portion, and the injecting glue process is fast when pouring into waterproof glue, and the sleeve pipe is glued fully in the pouring into glue, can be clear see waterproof glue fill overflow the sleeve pipe. And carry out the injecting glue behind the sleeve pipe, can carry out the injecting glue after putting the joint vertically, help waterproof glue to fill in the connecting portion through gravity self-flowing. Traditional side sets up the injecting glue window, mostly keeps flat the joint and carries out the injecting glue.
Preferably, the sheath includes front tube, transition pipe and back pipe, and the sleeve pipe is entangled to the front tube outside, and the back pipe overcoat is on the cable, and front tube and back pipe are connected respectively to the both ends of transition pipe, and the transition pipe is the toper pipe, and it has waterproof glue to fill between transition pipe and the sleeve pipe. After the sleeve glue injection is completed, the transition pipe is pushed forwards to extrude the waterproof glue overflowing from the rear end of the sleeve, and a space between the sheath and the sleeve is filled. Meanwhile, the conical transition pipe is extruded by the waterproof glue, and the front end of the rear pipe is pulled, so that the rear end of the rear pipe is sleeved with the cable.
Preferably, the transition tube is less thick than the front and rear tubes, and is an elastically deformable tapered tube. The elastic transition pipe can enable the waterproof glue to be pressed before solidification, and more gaps can be filled.
Preferably, the sleeve is a transparent tube body, and the waterproof glue is glue with a color different from that of the sleeve. The transparent or semitransparent sleeve pipe can directly see whether the waterproof glue fills the space between the sleeve pipe and the connecting part from the outside of the sleeve pipe after the waterproof glue with different colors is injected.
Preferably, the inner wall of the sleeve is provided with a diversion trench, and the notch of the diversion trench is arranged at the rear end of the sleeve. The guiding gutter can let the injecting glue needle pour into the sleeve into waterproof glue more easily.
Preferably, the inner wall of the sleeve is provided with an exhaust groove at the opposite side of the diversion groove. The air discharge duct can be when waterproof glue pours into the sleeve into the time with the air escape, improves the plumpness of sleeve injecting glue.
Through adopting foretell technical scheme, the beneficial effects of the utility model are that: the utility model discloses increased bushing structure, waterproof glue can pour into the cover earlier intraductal sheath of sheatheeing again, and bushing structure opens the structure of injecting glue window than the side and whether the injecting glue is full with the observation injecting glue more easily. The occurrence of poor waterproof and airtight performance of the joint caused by insufficient glue injection is greatly reduced. The utility model discloses a joint can realize 3 grades waterproof, and voltage standing wave ratio VSWR is less than 1.5 at 0-6GHz, the small and exquisite firm characteristic that is difficult for droing of outward appearance.
