Description

Technical Field

[0001] The invention relates to a hydraulic pressure resistant sealing adapter. Background Art

[0002] In equipment such as hydraulic oil motor pumps, the adapter needs to realize the transmission of electric energy and electric signals on the one hand, and on the other hand, it needs to withstand a certain hydraulic pressure for a long time and always maintain external sealing. At present, conventional sealed connectors all adopt plug-in structures, which require a large space and are inconvenient to use in application environments that only require electric energy or electric signal transmission under sealed pressure conditions. It also increases maintenance costs. Therefore, conventional connectors can no longer meet the use functions of electric energy or electric signal transmission in such hydraulic seals and small spaces without plug-in requirements.

[0003] For example, in the multi-oil circuit electrical and hydraulic transmission central swivel joint for automobile cranes disclosed in announcement number CN202880713U, an electrical cable is inserted into the side of one end of the swivel body and exits from the center of the other end of the swivel body to realize the transfer of electrical signals, but its input and output ends need to be rewired, and the lines need to independently withstand the pressure during hydraulic transmission. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a hydraulic resistant sealing adapter.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a hydraulically resistant sealed adapter, comprising an outer shell, wherein a partition perpendicular to the center of the outer shell is provided inside the outer shell, signal terminals and electric power terminals are respectively installed at both ends of the partition, the middle parts of the signal terminals and the electric power terminals are fixed in the partition through a glass insulator, and the partition is provided with insulating pads covering the two end surfaces of the partition.

[0007] The signal terminal and the power terminal have the same length, and both ends extend out of the glass insulator respectively.

[0008] Both ends of the signal terminal and the electric energy terminal are provided with wire grooves, and the opening side walls of the wire grooves are processed with notches.

[0009] A flange is also provided on the outer wall of one end of the glass insulator.

[0010] A plurality of annular grooves are processed in the middle of the outer wall of the glass insulator, and sealing rings are installed in the grooves.

[0011] The beneficial effect of the present invention is that by arranging two types of signal and power terminals in the adapter, the adapter is made to have both signal and power functions, and the connection between each power terminal and signal terminal and the partition is wrapped with insulating glass to achieve electrical isolation and thermal isolation between the terminal and the partition. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the present invention.

[0013] In the figure: 1-housing, 2-glass insulator, 3-signal terminal, 4-insulating pad, 5-sealing ring, 6-electric power terminal, 7-partition. DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0015] like Figure 1 As shown, a hydraulic pressure-resistant sealed adapter comprises a housing 1, wherein a partition 7 perpendicular to the center of the housing 1 is provided inside the housing 1, and a signal terminal 3 and an electric power terminal 6 are respectively installed at both ends of the partition 7, and the middle of the signal terminal 3 and the electric power terminal 6 are fixed in the partition 7 through a glass insulator 2, and an insulating pad 4 is provided on the partition 7 to cover the two end surfaces of the partition 7. By arranging two types of signal and electric power terminals in the adapter, the adapter has both signal and electric power functions, and the connection between each electric power terminal and signal terminal and the partition is wrapped with an insulating glass body to achieve electrical isolation and thermal isolation between the terminal and the partition.

[0016] Furthermore, the signal terminal 3 and the power terminal 6 have the same length, and both ends extend out of the glass insulator 2, which is convenient for wiring during use. The number of signal terminal 3 and power terminal 6 is set according to demand. Multiple signal terminal 3 and multiple power terminal 6 are evenly arranged and staggered in each row or column to form the maximum spacing between the terminals.

[0017] Furthermore, both ends of the signal terminal 3 and the power terminal 6 are provided with wire grooves, and the opening side walls of the wire grooves are processed with notches. The notches enlarge the opening of the wire grooves, making it easier to insert the wires into the wire grooves. At the same time, the notches also enable the opening of the wire grooves to expand flexibly to allow wires with larger diameters to be inserted.

[0018] Furthermore, a flange is provided on the outer wall of one end of the glass insulator 2 , and the flange fixes the adapter while strengthening the supporting strength of the housing 1 .

[0019] Furthermore, a plurality of annular grooves are processed in the middle of the outer wall of the glass insulator 2, and sealing rings 5 ​​are installed in the grooves. The sealing rings enable the adapter to meet the requirements of hydraulic and other environments requiring sealing.
