Description

Technical Field

[0001] This utility model relates to gear drive technology, and in particular to gear oil filtration technology, specifically, a plug-in sealed through-wall joint. Background Technology

[0002] In gear oil filtration technology, gear oil has low conductivity, while impurity particles in the oil, after being charged in a high-voltage electrostatic field, acquire the same polarity as the electrostatic field. When the oil is split into two streams, one flows through a positive electric field and the other through a negative electric field, then they mix. After mixing, the impurity particles of both positive and negative polarities attract each other, agglomerate, and grow larger, eventually being filtered out of the gear oil, thus purifying the oil.

[0003] When introducing high voltage static electricity, the connector of the wire must have good conductivity, be able to withstand high voltage without short circuit, meet sealing requirements, not leak oil, be easy to install, and avoid rotation, knotting, and loose fixing.

[0004] Therefore, it is necessary to provide a plug-in sealed through-wall joint to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a plug-in type sealed through-wall connector.

[0006] The technical solution is as follows: A plug-in type sealing through-wall joint includes a through-wall bolt, which is hollow and fixedly mounted on a steel plate by threads. One end of the through-wall bolt is connected to an external connector, and the other end is connected to an internal connector; The external connector includes an external wiring seat provided in the hollow cavity corresponding to the through-wall bolt, an external wiring is provided on the external wiring seat, and a waterproof connector and a cover are also provided for the external wiring. The internal connector includes an internal wire seat with a mating cover, and an internal terminal block is provided on the internal wire seat. One end of the internal terminal block is connected to the external wire via a terminal block.

[0007] Furthermore, the external line holder is secured by an external screw cap and fixedly installed on one side of the hollow cavity of the through-wall bolt.

[0008] Furthermore, the inner connector is fastened by the inner screw cap and fixedly installed on the other side of the hollow cavity of the through-wall bolt.

[0009] Furthermore, corresponding to the inner terminal block, a terminal nut is provided on the inner terminal block.

[0010] Furthermore, a terminal block is fixed to the other end of the inner terminal block by a lock nut.

[0011] Furthermore, the terminals are banana-shaped terminals.

[0012] Furthermore, a first sealing ring is provided at the joint between the inner wire seat and the inner terminal block, a second sealing ring is provided at the joint between the inner wire seat and the through-wall bolt, and a third sealing ring is provided at the joint between the through-wall bolt and the steel plate.

[0013] Compared with the prior art, this utility model is more securely fixed, has a clear function, a simple structure, and is easy to install. By installing in stages, the connector is installed before the wire is connected, which avoids damage to the cable and prevents the cable from twisting during the installation process.
