Description
This invention relates to the art of electrical connectors and,
particularly, to a single-pole plug connector for a shielded cable including a signal
wire or conductor, an insulating jacket and an outer shielding. The invention is
particularly applicable to coaxial cables.
A coaxial cable connector is known (US Patent 5,116,230) which has
dielectric means for mounting a signal terminal that terminates to a signal wire and
conductive grounding terminal means arranged outside the dielectric means having
piercing means to engage an outer shielding of the coaxial cable. The coaxial cable
connector discloses an outer insulating housing for mounting a plurality of terminals
for a plurality of coaxial cables.
Single-pole plug connectors are a mass-produced item that are
manufactured in many different configurations. There is therefore an ongoing need to
cost-effectively produce such single-pole plug connectors with existing assembly
machines, while maintaining a properly designed quality product.
An object of the invention is to provide a new and improved single-pole
plug connector for terminating a shielded insulated wire or coaxial cable which
can be produced inexpensively with existing assembly machines.
The single-pole plug connector of the invention includes a hollow
shielding sleeve of metal which constitutes the outer housing of the single-pole plug
connector, and a hollow insulating insert housing which mounts a hollow signal
terminal. The outer housing or sleeve includes a free cavity and collapsible insulation
piercing means for cooperation with the shielding and insulating jacket of the coaxial
cable. The signal terminal is of the insulation displacing or piercing type and is
activated when the insert housing is fully inserted into the outer housing or shielding
sleeve. Simultaneously, when terminating the signal wire, the piercing means of the
outer housing or shielding sleeve bites into the jacket of the coaxial cable to make a
connection therebetween.
In the preferred embodiment, hollow shielding sleeves are produced
from a single metal sheet in such a way that they remain attached to the sheet metal
strip from which they were produced in order to be fed in to an assembly machine in
rolled reels where the sleeves can be separated or cut from the reels. The collapsible
insulation piercing means is located in the interior of the shielding sleeve along with
the hollow, insulating insert housing. The insert housing is preferably a two-part
structure including a terminal housing member and an actuating housing member. A
signal terminal is inserted between the terminal housing member and the actuating
housing member and, together with the insert housing, is pre-assembled in the
shielding sleeve. In this form, the shielding sleeves, together with the pre-assembled
insert housings and signal terminals, remain on the residual portion of the sheet metal
strip and can be rolled up. Final assembly of the plug connector is effected by
introducing the shielded cable into the shielding sleeve with the signal wire or
conductor passing into the hollow signal terminal and the cable shielding passing into
the collapsible piercing means. Final assembly is effected by axially pressing the
parts together, thereby crimping the signal terminal which clamps and engages the
signal wire. The outside of the insulating insert housing is provided with grooves
having abutment surfaces and the wall of the shielding sleeve may be provided with
ridges or tabs, which engage each other and hold the parts firmly in position.
Further details of the invention are described with reference to the
drawing in which:
Figure 1 shows the components of a plug connector 10 for a shielded
cable 1 which includes a signal wire or conductor 2, a cable shield 3 , an inner jacket 4
and an outerjacket 5. The plug connector itself includes a hollow shielding sleeve 11,
a terminal housing member 12 and an actuator housing member 13 which together
form an insert housing, and a signal terminal 14. The signal terminal can have a
female socket configuration (as shown) or a male pin configuration.
The walls of the shielding sleeve 11 are stamped out of a metal sheet
and formed into shape. The shielding sleeves remain connected to a residual sheet
metal strip or carrier 15 so that the sleeves can be easily handled during assembly of
the plug connector. For that purpose, the carrier 15 includes transport and indexing
holes 16.
Opposing edges of the sheet metal from which the shielding sleeve is
folded are configured as shown at 17 and 18. These interleaved portions 17 and 18
engage one another with an undercut configuration, so that some tensile loading in the
peripheral direction of the shielding sleeve 11 is carried by the sleeve.
The insert housing, made up of terminal housing member 12 and
actuator housing member 13, is generally hollow and is fabricated of insulating
material such as plastic. The terminal housing member and the actuating housing
member have external grooves with abutment surfaces 25, 26 and internal cavities or
spaces 27, 28 which form through passages. Signal terminal 14 also has a hollow
configuration with a through passage and includes a collapsible plug portion 21
having termination engagement means 24, and a signal contact portion 22 which
connects with the plug portion at a step or shoulder 23. The collapsible plug portion
fits into cavity 27 in terminal housing member 12 and signal contact portion 22 fits
into cavity 28 of actuating housing member 13. When fitted together in that way, the
insert housing 12,13 can be pre-assembled into shielding sleeve 11, as shown in
Figure 2.
For final assembly of the plug connector, shielded cable 1 is inserted
into the opening formed between the insulation piercing means 31, and the pre-assembled
structure of Figure 2 is compressed by applying pressure, with a tool for
example, to the rear end 29 of the insert housing to push it further into the sleeve.
Signal terminal 14 is thereby terminated. This causes each limb of clamp portion 30
to be shortened and insulation piercing means 31 thereby penetrates outer shielding 3
of cable 1 and makes contact with the shielding. Ribs or actuating projection portions
33 disposed on actuating housing member 13 cooperate with the abutment surfaces 23
of signal terminal 14. In comparing Figure 3 with Figure 4, it can be seen that
actuating projection portions 33 penetrate into cavity 27 of terminal housing member
12 which is enlarged at an opening thereof in a funnel-shape configuration.
Collapsible portion 21 of signal terminal 14 includes termination engagement means
24 which penetrate the insulating jacket of cable 1 and makes contact with signal wire
2. The position of the insert housing may be secured by ridges or tabs 37, 38 on the
wall of shielding sleeve 11, which engage the abutment surfaces of terminal housing
member 12 and actuating housing member 13, respectively.
Figure 5 shows a perspective view of plug connector 10 prior to
assembly to the cable 1. As can be seen therefrom, shielding sleeve 11 is generally
rectangular or square shaped, either of which is desirable in terms of manufacture of
insulation piercing means 31.
The force applied to rear end 29 of the insert housing can be measured
by a suitable force-measuring device on the assembly tool, and it is possible to
determine whether the thrust force is in the correct range. If the dimensions are not
correct and/or the cable is not correctly inserted, the measured force will be outside
the permissible range, and faults can therefore be detected and corrected.
The step of separating the shielding sleeve from the carrier strip may
be effected prior to or after completion of the assembly procedure.
It will be understood that the invention may be embodied in other
specific forms without departing from the spirit or central characteristics thereof. The
present examples and embodiments, therefore, are to be considered in all respects as
illustrative and not restrictive, and the invention is not to be limited to the details
given herein.
