Description
Technical field
The utility model relates to charging pile technical field more particularly to charging cable waterproof techniques, and particularly one kind is filled
Electric stake flange form waterproof connector.
Background technique
With popularizing for new-energy automobile, charging pile becomes essential facility, in charging pile bin and charging gun electricity
Cable connecting portion, connectivity port need to carry out dust-proof, waterproof and anti-loosening processing.With the rapid increasing of charging pile installation number
Add, need to speed installation effectiveness and reduce installation cost, so as to quick response, meets and deliver delivery date.It is common currently on the market
Charging pile waterproof connector mainly uses thread connection, since collar nut hexagonal opposite side is big and inside has cable to pass through, does not fit
The automatic fitting tool matched, when installation, need two people to cooperate to cooperate, while needing to meet certain sky inside charging pile bin
Between surplus (bin inside must there are certain installation nut operating spaces), time and effort consuming, low efficiency are installed, fixing link takes
With big, it can not meet high efficiency, inexpensive requirement.
Summary of the invention
The purpose of the utility model is to overcome disadvantages of the existing technology, provide a kind of charging pile flange form waterproof
Connector is directly consolidated the ring flange on joint body with charging pile bin by bolt using the joint body of flange-type structure
Fixed connection substitutes the connection structure that traditional external screw thread adds locking nut, and it is low to solve conventional threads connection structure installation effectiveness, nothing
The problem of being adapted to installation tool, needing installation space in bin, the waterproof connector is easy for installation, and structure is simple and at low cost.
This charging pile flange form waterproof connector of the utility model, including joint body and lock nut, wherein described
Joint body is the pipe fitting that an one end has external screw joint, and the other end of the pipe fitting is provided with ring flange, described
Seal groove is equipped in the end face of ring flange, the seal groove is embedded with O-ring seals, and the lock nut passes through screw thread
It is cooperatively connected with the external screw joint of joint body, the inner wall of lock nut is equipped with step surface, sequentially coaxially sets in lock nut
Be equipped with an annulus gasket and a lip ring, the annulus gasket and lip ring be located at the step surface with
Between the end face at the external screw joint end of joint body, there are four connecting hole, the connecting hole is interior to be equipped with spiral shell for setting on ring flange
Bolt, the bolt are connect with the welding water-proof nut in charging pile bin.
Further, the ring flange of the joint body is square structure.
Further, circumferential groove is provided on the excircle disc of the lip ring.
Further, the annulus gasket is teflon plate.
Further, the bolt is hexagon socket head cap screw.
The working principle of the utility model is: in the installation process of charging pile bin cable, it first will be first by annulus
Sequentially, and lock nut is concentric fits into lock nut for gasket and lip ring, then in lock nut
Screw thread is connect with joint body external screw thread again, and lock nut is pre-installed on joint body (at this time without tightening).O shape is close
Seal is embedded in the seal groove of joint body flange pan bottom.Cable is sequentially passed through to lock nut, connector sheet outside bin
Body, O-ring seals and bin through-hole, joint body are cooperated by hole location, by 4 bolts by the electric screw driver of certain torque with
The welding water-proof nut locking of corresponding hole location, joint body is fixed on bin, the O shape that flange pan bottom is inlayed inside bin
Sealing ring is squeezed, and forms end face seal.Cable length is adjusted to appropriate location again, screws lock nut, in lock nut
Step surface and lip ring squeeze, realize the locking and sealing of cable.
The utility model compares with prior art, and effect is positive and apparent.The utility model uses flange form
Ring flange on joint body is directly fixedly connected by the joint body of structure by bolt with charging pile bin, substitution tradition
External screw thread adds the connection structure of locking nut, and it is low to solve conventional threads connection structure installation effectiveness, no adaptation installation tool, needs
The problem of wanting installation space in bin, the waterproof connector is easy for installation, and structure is simple and at low cost.
Detailed description of the invention
Fig. 1 is the configuration schematic diagram of the utility model.
