Description
Technical field
The utility model is related to connector technique field, especially a kind of waterproof construction of tail portion of connector attachment.
Background technology
To ensure electric connector stable operation work, it is desirable that cannot there is dust steam to enter inside connector.The prior art
Electric connector using tail portion be arranged rubber plug by the way of, realize the waterproof sealing of electric connector, the problem is that, work as connection
When the cable of device requires to draw a bonding line, current way is that bonding line is attached on the outside of cable, finally
Cable is passed through into rubber plug together with bonding line together, leads to the periphery discontinuity of rubber plug cable aperture, is equipped with bonding
The position of line easily causes gap so that rubber plug can not play sealing function well, to cause the sealing performance of connector to drop
Low or even failure.
Utility model content
The purpose of this utility model be in view of the deficiencies of the prior art and provide a kind of connector tail portion waterproof construction,
The utility model uses the setting ground connection string holes on rubber plug, is arranged semicircle orifice on washer, and when installation, cable is passed through rubber plug electricity
Bonding line is passed through the ground connection string holes of rubber plug and the semicircle orifice of washer, when cable hood and tail portion by the endoporus of cable hole and washer
When shell docks, rubber plug uniform-compression in the cone hole of tail portion shell deforms, and realizes the utility model tail portion of connector waterproof
Purpose, have the advantages that simple, easy to assembly, sealing structure is reliable and water resistance is good.
Realizing the specific technical solution of the utility model aim is：
A kind of tail portion waterproof construction of connector, feature include cable hood, washer, rubber plug and tail portion shell；The electricity
Cable cover is the interior tubular element for setting gasket groove and internal thread, is the sheet shaped piece of washer annular, and the inner wall of annular is equipped with semicircle orifice,
The conical sheet metal of cable aperture is equipped with centered on rubber plug, be equipped with parallel with cable aperture is grounded string holes on the wall thickness of rubber plug, outside tail portion
Shell sets cone hole, the externally threaded tubular element of peripheral hardware in being；
The washer is set in the gasket groove of cable hood, and rubber plug is set in the cone hole of tail portion shell, cable hood and tail portion
Shell docks, and the internal thread of cable hood is engaged with the external screw thread of tail portion shell.
The utility model uses the setting ground connection string holes on rubber plug, is arranged semicircle orifice on washer, and when installation, cable is worn
Bonding line is passed through the ground connection string holes of rubber plug and the semicircle orifice of washer, works as cable by the endoporus for crossing rubber plug cable aperture and washer
When cover is docked with tail portion shell, rubber plug uniform-compression in the cone hole of tail portion shell deforms, and realizes the utility model connector
The purpose of tail portion waterproof has the advantages that simple, easy to assembly, sealing structure is reliable and water resistance is good.

Specific implementation mode
Refering to fig. 1, Fig. 2, Fig. 3, the utility model include cable hood 11, washer 12, rubber plug 13 and tail portion shell 14；It is described
Cable hood 11 is the interior tubular element for setting gasket groove 111 and internal thread, is the sheet shaped piece of 12 annular of washer, is set on the inner wall of annular
There is a semicircle orifice 121, is equipped with the conical sheet metal of cable aperture centered on rubber plug 13, it is parallel with cable aperture on the wall thickness of rubber plug 13 to be equipped with
It is grounded string holes 131, tail portion shell 14 sets cone hole, the externally threaded tubular element of peripheral hardware to be interior；
The washer 12 is set in the gasket groove 111 of cable hood 11, and rubber plug 13 is set in the cone hole of tail portion shell 14, electricity
Cable cover 11 is docked with tail portion shell 14, and the internal thread of cable hood 11 is engaged with the external screw thread of tail portion shell 14.
The utility model works in this way：
Refering to fig. 1, Fig. 2, Fig. 3 are equipped with the conical sheet metal of cable aperture centered on the rubber plug 13 of the utility model, in rubber plug 13
Wall thickness on it is parallel with cable aperture be equipped with ground connection string holes 131, on the annular inner wall of washer 12 be provided with semicircle orifice 121；
Refering to fig. 1, when installation, by gasket groove 111 of the washer 12 loaded on cable hood 11, shielding is connect by Fig. 2, Fig. 3, Fig. 4
Ground wire 15 passes through the ground connection string holes 131 of rubber plug 13 and the semicircle orifice 121 of washer 12 and is drawn by cable hood 11, and cable 16 is passed through
The cable aperture of rubber plug 13 and the endoporus of washer 12 dock tail portion shell 14 with cable hood 11, with the internal thread of cable hood 11
Externally threaded with tail portion shell 14 gradually engages, under the barrier effect of washer 12, cone of the rubber plug 13 in tail portion shell 14
Uniform-compression deforms in hole, and cable 16 and bonding line 15 are tightened, embraced by the cable aperture and ground connection string holes 131 of rubber plug 13 respectively
Extremely, realize that the purpose of the utility model tail portion of connector waterproof, the utility model are suitable for the severe occasion of outdoor environment, can have
Effect prevents water and dust from entering inside connector, and reliable with simple, easy to assembly, sealing structure and good water resistance is excellent
Point.
