Patented May 18, 1954 THROUGH-'CLAMP FOR`COAXIAL CABLES Thomas',v H. Everhart, Cedar' Rapids, Iowa, as.-` signorto Collins Radio Co.,..(ledar` Rapids, Iovva,V

a corporation of Iowa Application June 27, 1951,' SeriaIINo: 233,867'

(Cl. 17a- 48) 3 Claims. l

This .invention relates in general to fastening meansandin particular to means for fastening a coaxial line andsimultaneously grounding the sh'ield.

Coaxial line is used more and more in radio and television circuits and it is oftentimes desirable to have the wire connect points separated a relatively large distance'. The conductor should be'vfastened to vthe chassis at intermediate'points or where it passes from one chassis to another. It is desirable to ground the outer shield when it is fastened to a chassis.

It is an object of this invention, therefore, to provide a holding means for a conductor which simultaneously grounds the shield to the holding means.

Another object of this invention is to provide a coaxial conductor holding means which grounds the outer shield and maintains a rigid grip on the conductor.

Yet another object is to provide an economical and easily manufactured shielded conductor holding means.

A feature of this invention is found in the provision for a collar receivable through an opening formed in a chassis and supported on the chassis by suitable holding means, and having an internally threaded opening in which a threaded male member may be received. A coaxial conductor passes through axial openings formed through the collar and male member, and the shield is clamped between the male member and the collar member.

Further objects, features, and advantages of this invention will become apparent from the fol- :i

lowing description and claims when read in View of the drawings, in which:

Figure 1 is an isometric View of the coaxial line holder of this invention; and,

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

A coaxial line, designated generally as I0, comprises an inner conductor Il surrounded by insulating material I2 which might be, for example, polystyrene, and which is in turn encased E id. This-is'best shown'in Figure'2. A holding means as, for example, a nut 2 I, is received over thethreaded portionto clamp the collar to the chassis.

The opposite end of the collar is formed with aninternally threaded opening 22. A second collar 23Y is formed with an axial opening 24 through which the line extends. The collar 23 has a threaded portion 25 which may be threadedly received into the opening 22. A shoulder 2'! is formed at the end of collar 23. A head 28 is formed on the collar so that it may be rotated by a wrench or other suitable driving means.

A section of the outer insulation I4 of the coaxial line is removed from the shield I3 with a knife or other suitable means and the two adjoining portions of the insulating material I4 are pushed together, thus causing the shield I3 to expand out through the opening 29 to form an enlarged diameter portion 3|. The coaxial line has enough slippage between adjoining layers to allow the outer insulator to be pushed together.

The portion 3l is clamped between the shoulder 21 and an inner shoulder 32 in the collar I6 i by insertingl member 23 into collar I6. Collars i5 and 23 are made of conducting material as, for example, copper, and thus the shield I3 is electrically connected to the chassis IS. The clamping action of the shoulders 2l and 32 on the projection 3| prevents the line from moving longitudinally through the chassis.

Thus, it is seen that means are provided for attaching a coaxial line to a chassis in a manner such that longitudinal motion is prevented and while simultaneously grounding the outer shield of the conductor. The insulation at either side of the connection is still maintained, whereas previously all the insulation on one side of the connection has been stripped. A bare conductor is dangerous and oftentimes shorts terminals in the chassis.

Although the invention has been described with respect to a preferred embodiment thereof, it is not to be so limited as changes and modifications may be made therein which are Within the full intended scope of the invention as dened by the appended claims.

I claim:

1. Means for holding a coaxial line while simultaneously grounding the outer conductor comprising, an enlarged portion formed in said coaxial line by removing the outer insulation and telescoping the outer conducting shield, a collar formed with an internal threaded opening through which the line extends, the collar being formed with an internal shoulder, the enlarged portion of said coaxial line received against said shoulder, and externally threaded holding means formed with an axial opening through which the coaxial line extends threadedly received within said threaded opening to clamp the enlarged portion of said coaxial line against the shoulder,

2. Means for fastening to a chassis a coaxial line having an internal and outer conductor with insulation between the conductors and external insulation comprising, a collar formed with an internal axial opening through which the line extends with a portion of said opening internally threaded and enlarged, first holding means attaching said collar to said chassis, second holding means formed with an axial opening through which the line extends and having an externally threaded portion threadedly received within the threaded opening of said collar, a portion of the external insulation being removed from said line to allow the outer conductor to be telescoped into a diameter larger than the line, and said second holding means clamping the enlarged portion of said outer conductor against the collar.

3. Means for fastening to a chassis a coaxial line and simultaneously grounding the outer shield of a line which has an internal conductor land outer conductor with insulation between the conductors and outer insulation about the external conductor comprising, a collar fastened to the chassis and formed with an axial opening, a portion of said axial opening internally threaded and larger in diameter than the remaining portion, a projection formed on said line by removing a ring of the outer insulation and telescoping the external conductor, an externally threaded holding means formed with an yaxial opening, the line being received through the collar and the holding means with the enlarged portion of the outer conductor there-beltween, and the holding means being threadedly received in said collar to clamp the enlarged portion of the coaxial line between the collar and the holding means.
