ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention herein relates to a guide tube utilized as a tool capable of guiding the assembly of coaxial cable conductors to an end connector in a simple operation and, furthermore, the said guide tube can be carried by working personnel and is capable of continuous and repeated usage.
2. Description of the Prior Art
In cable television systems(CATV),subscription television systems(STV), and master antenna television systems(MATV), terminal, and other systems, the signals are transmitted by means of coaxial cable. Referring to
FIG. 1
, the conventional coaxial cable connector of such systems is comprised of the coaxial cable
10
itself and an end connector
11
; the installation personnel must effectively insert the cable
10
into the end connector
11
such that the center conductor
12
and the dielectric
13
are inserted through the inside of a hollow body
14
of the end connector
11
, while the braided conductor
15
and the outer jacket
16
are sleeved around the extended rear section
17
of the hollow body
14
and, finally, a ring
18
is crimped over the coaxial cable
10
to bind it firmly to the extended rear section
17
; however, since the inner diameter of the said hollow body
14
is slightly larger that the outer diameter of the dielectric
13
, the installation personnel have an extremely difficult time inserting the dielectric
13
into the hollow body
14
; furthermore, if the braided conductor
15
is in a state of disarray, the installation personnel experience further difficulty while inserting the dielectric
13
through the hollow body
14
, which poses tremendous installation problems; as such, the industry is currently awaiting a solution to the said shortcomings to increase competitiveness.
In view of the said situation, the inventor of the inventor herein conducted intensive research based on many years of experience accumulated while engaged in the production and marketing of related products which, following continuous testing and refinements, finally culminated in the development the guide tube of invention herein.
SUMMARY OF THE INVENTION
Therefore, the primary objective of the invention herein is to provide a guide tube that is ensleeved over the coaxial cable conductors, thereby enabling the guide tube to be capable of easily inserting the conductors and dielectric of the coaxial cable onto the hollow body of the coaxial cable end connector.
To enable a further understanding of the innovations and technological content of the invention herein, the brief description of the views below are followed by the detailed description of the preferred embodiments, which are provided for purposes of reference and elaboration and shall not be construed as any limitation whatsoever of the invention herein.
