Abstract
Abstract A pressurized water-proof connection for connecting an electrical cable to a housing of an electrical sensor is disclosed. An intermediate housing for connecting the electrical sensor contains a coupling piece electrically connected to the sensor with contact elements and a collar having an internal thread and with coupling sleeves directed in the axial direction of said collar. A plug with contact elements connected to electrical wires of an electrical cable is insertable through the collar. A closure sleeve has a thread portion for the internal thread of the collar and also a thread for a screw-type cable fitting for the electrical cable.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A pressurized water-proof connector for connecting an electrical cable to an electrical sensor comprising: an intermediate housing for connecting to an electrical sensor said housing containing a coupling piece which is electrically connectable to the sensor with contact elements, a collar having an internal thread, and coupling sleeves disposed in the axial direction of said collar; a plug with contact elements connectable to electrical wires of an electrical cable, said plug being insertable through said collar; and a closure sleeve having a threaded portion for engaging the internal thread of said collar and having a screw-type cable fitting for an electrical cable.
Claim 2
Dependent Claim
102 words
A pressurized water-proof connector for connecting an electrical cable to an electrical sensor comprising: an intermediate housing for connecting to an electrical sensor said housing containing a coupling piece which is electrically connectable to the sensor with contact elements, a collar having an internal thread, and coupling sleeves disposed in the axial direction of said collar; a plug with contact elements connectable to electrical wires of an electrical cable, said plug being insertable through said collar; and a closure sleeve having a threaded portion for engaging the internal thread of said collar and having a screw-type cable fitting for an electrical cable.
Claim 3
Dependent Claim
28 words
A connector according to claim 1, wherein the elements of the plug are provided as sleeves and the contact elements of the coupling piece are provided as pins.
Claim 4
Dependent Claim
19 words
A connector according to claim 1, wherein the plug comprises spring clamps as contact elements for the electrical cable.
Claim 5
Dependent Claim
21 words
