Abstract
Abstract A radiation tight connection device for a cable containing a screening mesh or wire which is fixed by clamping. An insert equipped with an insert cone and a collar formed thereat is inserted substantially axially parallel in a conical bore of a screw cap or retaining nut. Provided at the insert cone is an external or outer conical contact surface which corresponds to or is complementary to an inner contact surface of the conical bore of the retaining nut. During assembly the screening wire or mesh is fixed by clamping between both of the contact surfaces. The invention preferably is used in conjunction with plugs or the like.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A radiation tight connection device for a cable having a shielding meshwork fixed by clamping, comprising: an insert member equipped with an insert cone; a collar formed at the insert cone; a retaining nut having a substantially conical bore; said insert member being inserted into the conical bore of said retaining nut; a substantially conical contact surface provided at said insert cone; said conical bore of said retaining nut having a contact surface; the conical contact surface of the insert cone essentially corresponding to the contact surface of the conical bore of the retaining nut; and the shielding meshwork exclusively being fixedly retained between both of said contact surfaces by clamping thereof.
Claim 2
Dependent Claim
112 words
A radiation tight connection device for a cable having a shielding meshwork fixed by clamping, comprising: an insert member equipped with an insert cone; a collar formed at the insert cone; a retaining nut having a substantially conical bore; said insert member being inserted into the conical bore of said retaining nut; a substantially conical contact surface provided at said insert cone; said conical bore of said retaining nut having a contact surface; the conical contact surface of the insert cone essentially corresponding to the contact surface of the conical bore of the retaining nut; and the shielding meshwork exclusively being fixedly retained between both of said contact surfaces by clamping thereof.
Claim 3
Dependent Claim
28 words
The connection device as defined in claim 1, wherein: the contact surface of the insert cone and the contact surface of the retaining nut define respective Morse cones.
Claim 4
Dependent Claim
31 words
The connection device as defined in claim 2, wherein: the collar of the insert cone is offset by a substantially ring-shaped recess from the conical contact surface of the insert cone.
Claim 5
Dependent Claim
55 words
The connection device as defined in claim 2, wherein: said retaining nut has a recess; said insert member having a recess; and in the assembled condition of the connection device the recess of the retaining nut and the recess of the insert member defining a substantially torous-shaped channel for receiving part of the shielding meshwork.
Claim 6
Dependent Claim
25 words
The connection device as defined in claim 1, further including: a plug-end housing threadably connected into the retaining nut for additionally fixing the insert member.
