Definitions
- the present invention relates generally to a connector for cables or more particularly to a moisture-inhibiting sealing system for connectors which accommodates cables.
- the object of the present invention is to eliminate the problems and drawbacks in connection with the use of O-rings in sealings between the cable and connector device with regard to the leakage of moisture into the device.
- the invention solves these problems by introducing a sealing means which forms a hermetic seal with both the cable jacket and the exposed cable outerconductor, in effect giving a hermetic double seal.
- the sealing means is formed such that large areas, compared to O-ring methods, are in contact with the surfaces to be sealed resulting in a substantially larger barrier for moisture to penetrate, which also covers any physical defects in the cable.
- the backnut In an open state, the backnut is screwed forward which allows the cable to be inserted freely.
- the sealing means is sandwiched between the inserted cable and tightened backnut with an additional lateral force applied by the ferrule, thus forming a hermetic seal between the backnut and inserted cable.
- a further object of the invention is to provide a more secure gripping means for the cable. This too is achieved by the substantially larger cable area which comes into contact with the sealing means.
- Figure 1 is a longitudinal cross-section of the connector in its open position
- Figure 2 is a longitudinal cross-section of the connector in its closed position.
- Figure 1 illustrates an embodiment of a connector according to the invention in its open state, which enables a cable to be moved freely within the connector.
- the innerconductor 12 of the cable comes into contact with the innerconductor 7 of the connector which is located in the centre of the insulator 2 which in turn is positioned in the centre of the outerconductor front part 3.
- the connections between each part include a seal of some sort which is substantially hermetic and which in this embodiment takes the form of O-rings 8 and 9, respectively.
- These parts are rigidly connected to each other and remain static throughout the opening and closing procedures.
- the backnut 5 In its open state the backnut 5 is fully extended allowing enough room for the cable to pass freely between the backseal 4 and ferrule 6.
- Figure 2 illustrates the connector in its closed state where the foam 13 of the cable abuts the inner rim of the outerconductor front part 3 and the outerconductor 14 of the cable is in contact with and pressed between the ferrule 6 and the rim of said outerconductor front part 3.
- the backnut 5 being tightened until it is in its closed position.
- This also forces the backseal 4 to clamp onto and secure itself around the exposed outer conductor 14, while its front end engages and presses against the cable jacket 11.
- the O-ring 10 which forms the seal between the outer rim of the outer conductor front part 3 and the backnut 5
- the cable insertion end is sealed.
- One embodiment of the invention is particularly suited for a cable with a corrugated outerconductor, where the backseal 4 is stepped with an thin outer portion and thicker inner portion.
- the backseal 4 is brought into contact with the ferrule 6 which applies a lateral pressure to it as well as ensuring a contact between the cable outerconductor 14 and the outerconductor front part 3.
- the backnut 5 has a lip at its outer edge, which also exerts a lateral pressure on the backseal 4; thus the backseal 4 is effectively sandwiched between the two and prevented from lateral movement.
- the outer portion of the backseal 4 seals around the cable jacket 11 and the inner portion is moulded and seals around a corrugation in the outerconductor 14 of the corrugated cable.
- double seal according to the invention has been described above in connection with a cable comprising a corrugated outerconductor, it is understood that it can also be used in connectors adapted for cables with a non-corrugated outerconductor.
- the back seal 4 is a ring of flexible, durable and waterproof material (for example a silicone or rubber based material or thermoplastic such as TPE) which has a certain outer diameter and two inner diameters giving a stepped effect.
- the back seal is also a ring of flexible, durable and waterproof material with a certain outer diameter and having two different diameters at its opposing ends with the inner diameter tapering from the larger end diameter to the smaller. As described above, the function of the differing diameters is to accommodate the cable jacket 11 within the larger diameter and the cable outer conductor 14 within the smaller diameter.
