Embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is carried out clear
Chu, it is fully described by.
The present invention relates to a kind of cable waterproof construction 100 and the communication products with the cable waterproof construction 100.Cable
Waterproof construction 100 is used to realize the waterproof between cable and the casing of communication products.As shown in Figures 1 and 2, the present invention is provided
A kind of cable waterproof construction 100 includes joint 10, locking folder 20, locking cap 30 and waterproof inner core 40.The joint 10, the lock
The hollow form that 20, the waterproof inner core 40 and the locking cap 30 are in both ends open is gripped, so that the cable is passed through.This reality
Apply in mode, the joint 10, the locking folder 20, the waterproof inner core 40 and the locking cap 30 are axially symmetric structure.
Fig. 1 is referred to Fig. 4, the locking folder 20 includes location division 24, connecting portion 222, multiple clamp jaws 224, block
Ring 26 and groove 21.Connecting portion 222 is installed on clamping part 22 with multiple clamp jaws 224 formation clamping part 22, waterproof inner core 40
Inner surface.The location division 24 inserts the joint 10 and is connected to the inner surface of the joint 10, and the locking is pressed from both sides into 20
The joint 10 is positioned at, the connecting portion 222 is directed away from the direction extension of the joint 10 from the location division 24, described
Multiple clamp jaws 224 are directed away from the direction extension of the location division 24, and two adjacent clamp jaws from the connecting portion 222
Clearance G is provided between 224 so that the flexible deformability of the multiple clamp jaw 224, the stop ring 26 is connected to described
The inwall of connecting portion 222 and close to the location division 24, the groove 21 located at the stop ring 26 and the connecting portion 222 it
Between.In present embodiment, the multiple clamp jaw 224 is arranged on same circumference, and the multiple clamp jaw 224 is in radial direction
Upper flexible deformability.
The waterproof inner core 40 includes main body 42, insertion section 44 and positioning table 46, the insertion section 44 and the positioning table
46 are located at one end of the main body 42, and the insertion section 44 is based in the periphery of the positioning table 46 and surrounds the positioning table
46, the waterproof inner core 40 is installed on the inner surface of the connecting portion 222 and the multiple clamp jaw 224, the insertion section 44
Insert in the groove 21, and coordinate with groove 21, insertion section 44 is closely tied in the groove 21 to strengthen waterproof effect,
The positioning table 46 is close to the stop ring 26.
The locking cap 30 is sheathed on the periphery of the multiple clamp jaw 224, and the locking cap 30 lock onto the joint
10 cause the multiple clamp jaw 224 to hold the waterproof inner core 40 in the outer surface of the cable tightly.
The cable waterproof construction 100 presss from both sides the attachment structure between 20 by waterproof inner core 40 and locking, that is, described
Matching relationship between the insertion section 44 of waterproof inner core 40 and positioning table 46 and the groove 21 and stop ring 26 of locking folder 20, i.e. institute
State insertion section 44 and insert the groove 21, the positioning table 46 is close to the stop ring 26, forms the waterproof of anti-labyrinth structure
Path so that the cable waterproof construction 100 has reliable water resistance,
Specifically, the material of waterproof inner core 40 is rubber, and the main body 42 of the waterproof inner core 40 is in the form of a column sleeve shaped,
The elasticity that has by waterproof inner core 40 material itself is so that waterproof inner core 40 is tightly coated on the outer surface of cable, thereby,
Sealing is formed between waterproof inner core 40 and cable.The cooperation of the locking cap 30 and the joint 10 causes the locking folder 20 to press from both sides
