Brief description of the drawings
Fig. 1 is the exploded perspective view of the above-mentioned waterproof electrical connector of the utility model；
Fig. 2 is the cut-away illustration of the above-mentioned waterproof electrical connector of the utility model.
Label declaration：Electric wire 1, outer cover body 2, tube-like envelope 21, jack panel 22, connecting tube 23, through hole 24, marine glue core
3rd, sheath 4, cable-through hole 5, ring-type internal projection 51, nut bonnet 6.
Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.
Refer to Fig. 1 and Fig. 2, a kind of waterproof electrical connector, including outer cover body 2, one end and fill in preventing in outer cover body 2
Glue core 3, the sheath 4 for being sheathed on the other end of marine glue core 3.It is provided with and is electrically connected for electric wire 1 through introducing in marine glue core 3
Multiple cable-through holes 5 inside device, a nut bonnet 6 is coated on sheath 4, and matches somebody with somebody with one end of outer cover body 2 for filling in marine glue core 3
Conjunction is tightened, so as to reduce the cross-sectional area of cable-through hole 5 so that the inwall of cable-through hole 5 is adjacent to electric wire, prevents moisture out of cable-through hole
Into electrical connector interior.Marine glue core 3 is made of elastomeric material, such as PVC material.
Each inwall of cable-through hole 5 is each formed with the ring-type internal projection 51 for close electric wire of fitting.The ring-type internal projection 51
Laminating electric wire, prevents moisture from entering electrical connector interior from cable-through hole 5.Cable-through hole 5 is puncture type terminal structure, accordingly even when mistake
String holes 5 does not stick with electric wire completely, can still play a part of waterproof, prevents moisture from entering from the cable-through hole 5 for not passing through electric wire.
Outer cover body 2 includes tube-like envelope 21, the jack panel 22 of peripheral connecting pipes shape outer casing inner wall and from jack panel 22
On the externally threaded connecting tube 23 of band that extends vertically；Multiple through holes 24, the protruded tube of connecting tube 23 are formed with jack panel 22
One end of shape shell 21, connecting tube 23 is spirally connected with nut bonnet 6.Electric wire 1 passes through through hole 24, is connected to electrical connector interior.
Marine glue core 3 is in the form of a column, and multiple cable-through holes 5 run through its both ends of the surface and corresponding with multiple through holes 24, close in cable-through hole 5
Seal electric wire 1；Ring-type water proof ring 31 is formed with the outer surface of one end of the close outer cover body 2 of marine glue core 3, it is anti-with ring-type
It is interference fitted in one end insertion connecting tube 23 of hydrosphere 31 and with connecting tube 23 so that marine glue core 3 has ring-type water proof ring 31
One end extruded joint pipe 23 inwall.
Sheath 4 is enclosed on the other end of marine glue core 3, and its external diameter is more than the internal diameter of connecting tube 23.The inwall extruding connection of sheath 4
The outer wall of pipe 23, so as to play a part of waterproof.
The first end of nut bonnet 6 is formed with the internal thread matched with the external screw thread of connecting tube 23, and it does not form interior spiral shell
The size of the part of line is tapered into away from internal thread so that the second end of nut bonnet or the portion close to its second end
The internal diameter divided is less than the external diameter of sheath.Nut bonnet 6 is screwed in connecting tube 23 so that its first end inserts tube-like envelope 21
It is interior, and marine glue core 3 and sheath 4 be compressed in the space that outer cover body 2 and nut bonnet 6 are surrounded.
When moisture from the path of marine glue core 3 with the junction of outer cover body 2 enters fashionable, as shown by the arrows in figure 2, it is known that this
Path is longer, and needs the connection of be spirally connected position and the marine glue core 3 and outer cover body 2 through nut bonnet 6 and outer cover body 2
Position, and nut bonnet 6 is spirally connected with outer cover body 2, therefore with certain water resistance.In addition, nut bonnet 6 and shell sheet
Body 2 is made of waterproof material.
Above-mentioned waterproof electrical connector, good seal performance is greatly improved the water resistance of electric connector, for a long time in the depth of water
Good waterproof effect is maintained in the environment of one meter.After tested, in the environment of one meter of the depth of water waterproof of 48 hours can be maintained to imitate
Really.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
Protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
