Technical field
The utility model is related to electricity field more particularly to cable connectors, especially a kind of compression type electromagnetic shielding is anti-
Water swivel.
Background technology
In electrical equipment and cable segment connector, need to carry out dust-proof, waterproof, anti-loosening to connectivity port, and ensure good
Good shield effectiveness.Waterproof connector of cable is generally used at present, inside electric appliance and external environs is got up, to be used for
Ensure safety and the reliability of its electrical equipment, the structure which uses be in metal shell, inside be subject to nylon core retainer plate,
Rubber seal, spring forms an entirety, its shortcoming is that the use in high pressure high sealing place cannot be met, under high pressure,
Sealing performance is there will be hidden danger, and spring has an ejection risk when installation, and spring is easy to contact not with cable shield under vibration environment
It is good, the use of electrical equipment high request cannot be met.
Utility model content
The purpose of this utility model is to provide a kind of compression types solving above-mentioned technical problem to be electromagnetically shielded waterproof connector.
In order to solve the above technical problems, compression type provided by the utility model is electromagnetically shielded waterproof connector, including：Connector sheet

Description of the drawings
Fig. 1 is that the utility model compression type is electromagnetically shielded waterproof connector explosive view；
Fig. 2 is that the utility model compression type electromagnetic shielding waterproof connector uses schematic diagram one；
Fig. 3 is that the utility model compression type electromagnetic shielding waterproof connector uses schematic diagram two.
Specific implementation mode
The utility model compression type electromagnetic shielding waterproof connector is described in further detail below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, the utility model compression type is electromagnetically shielded waterproof connector, including a joint body 1, connects
Head ontology 1 is made of a conductive tubular element, and there are one metal T-type shielding cylinder 5, a compressions for the coaxial arrangement of connector one end
Ring 4, a sealing element 3, there are one lock nut 2, lock nut 2 is connect by screw thread with joint body 1 for outside setting, is locked
The inside of nut 2 is provided with the conical surface coordinated with sealing element 3, and axially extending bore is provided in lock nut 2.Utilize lock nut 2
Internal conical surface oppress the taper seal 3 contraction and realize good sealing performance to compress the cable 10 that passes through.
One O-ring seal 9 is installed in the mounting portion 8 of 1 other end of joint body and the junction of joint body 1.
Operation principle：Remove restrictive coating 11 for cable 10, exposes the state of shielding silk, the cable 10 stripped is penetrated successively
Nut 2, chuck sealing element 3, shielding compression ring 4, the sleeve 7 of metal T-type shielding cylinder 5 is pierced into the restrictive coating 11 of harness, will
Harness penetrates in joint body 1, and the pedestal 6 of metal T-type shielding cylinder 5 is fitted in joint body 1 in the slot of bottom end.Make electricity
The shielded layer of cable 10 comes into contact in a large area with metal T-type shielding cylinder 5, and shield effectiveness greatly improves, and is suitble to make on new-energy automobile
With, and it is quick for installation.The influence of water penetration can be effectively prevented by the sealing element 3 and an O-ring seal 9 of assembly,
Reach high sealing effect；One end of joint body 1 and the installation of electrical box, using an O-ring seal 9, by O-ring seal 9
In the slot of joint body 1 Yu the junction of mounting portion 8.Pass through threaded connection with equipment threaded hole and O when installation
Type sealing ring 9 seals to realize.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to the embodiment, those skilled in the art can also make various under the premise of without prejudice to the invention spirit
Equivalent modification or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
