[0001] The present patent application relates, as stated in its title, to a "TERMINAL DIRECTING
STATION", which novel manufacturing, conformation and design features fulfil the purpose
to which they have been specifically conceived, with a maximum safety and effectiveness.
[0002] More particularly, the present invention refers to a terminal directing station arranged
next to other stations in a cable processing machine. The purpose of such machine
is to perform a number of operations on the cables by automatic means, such as their
selection, identification or marking, cutting and peeling, insertion of rubber, insertion
of terminals and positioning said terminals into the corresponding cavities of different
types of connectors.
[0003] As a result of the purpose of the machine and as it comprises various stations having
different functions; the station of the present invention comprises a frame formed
by standardised section members supporting a bed having a pivot actuator mounted thereon
by a suitable support. The actuator is provided with special gripping members with
grips have different length and the distance therebetween is manually adjustable.
Said grips act on the corresponding cable which is provided with the rubber and the
terminal.
[0004] The terminal directing station collects the cable or the cable portion which has
been already provided with the rubber and the terminal and it locates said cable into
a programmed position in such a way that subsequently the cable is allowed to enter
the corresponding cavity in the connector by means of another station.
[0005] As usefulness of such machine permits working with different types of connectors
having cavities of different shaped geometry, it is necessary that said machine is
provided with a station capable of positioning the terminal in the proper position
so that said terminal can properly enter such cavities by means of a terminal positioning
station. The cavities have been designed to receive a number of retaining elements
causing the terminal to enter in one single position. Said position determines the
entering way of the terminal as well as the insertion thereof inside the cavity through
the retaining means provided therein. Said retaining means are complementary of the
shaped geometry of the terminal and complementary of that in the inside of the cavity
so that said retaining function can be achieved.
[0006] The terminal directing station is fed by an endless belt provided with a series of
gripping members attached at regular distances to one another. Between the grips of
said gripping members the cable is held once it has been processed in the other stations
until it has been disposed in front of the station of the present invention. Therefore,
such station is provided with a presence sensor element which starts the station as
the translation gripping member has been stopped with the cable in front of said station.
At this time, the gripping member which is attached at the end of the pivot actuator
swoops down on the cable and on the end of the terminal which is fastened. Then, the
translation gripping member releases the cable so that the directing station can actuate
disposing the terminal in the proper position in such a way that it can be clamped
again by the translation gripping member located over the endless belt and then conveyed
to the next station.
[0007] A detailed list of the different parts cited in the description mentioned according
to the accompanying figures is given hereinbelow: (10) station, (11) chassis, (12)
standardised section members, (13) sideplates, (14) bracket, (15) tray, (16) gripping
member, (17) arms, (18) endless belt, (19) cylinder, (20) sensor element, (21) cable,
(22) rubber, (23) terminal, (24) gripping member, (25) grips, (26) pivot actuator,
(27) gripping tips, (28) support, (29) sideplate, (30) grip support, (31) screws,
(32) frame, (33) table, (34) base, (35) screws, (36) bed, (37) pressing member, (38)
spring, (39) screws.
[0008] Figure n° 1 is a part-way section side view of the station (10) for directing terminals
(23).
[0009] Figure n° 2 is a closer view of the pivot actuator (26) mounted in the gripping members
(24) provided with grips (25) having gripping tips (27).
[0010] In one of the preferred embodiments of what is the object of the present invention
and as it can be seen from figures n° 1 and 2, the station (10) comprises means for
conveying the cables (21) which are fed into the different stations in the machine
that is not shown in the figures. The machine comprises an endless belt (18) provided
with gripping members (16) attached at different distances to one another and having
arms (17). Said parts are mounted on section members (12) fastened by means of a bracket
(14) in which upper part a tray (15) is provided. Said tray (15) prevents the different
parts in the station (10) and the machine from being interfered by the cables (21).
[0011] The station (10) comprises a frame (32) mounted on section members (12) acting as
longitudinal members and cross members. On said frame (32) a bed (36) is mounted supporting
a table (33) which purpose is to fit a base (34) on which a support (28) is mounted.
The support (28) is reinforced with a sideplate (29) and it is provided with a pivot
actuator (26) located at the upper end thereof. The pivot actuator (26) has a gripping
member (24) which grips (25) are provided with gripping tips (27).
[0012] The grips (25) are provided with such gripping tips (27) so that these grips (25)
can engage the different types of terminals (23) and cables (21), see figure n° 2.
The tips (27) have different length so that the cable (21) can be held by one gripping
tip (27), whilst the terminal (23) can be held by the other gripping tip (27). Between
said tips (27) a means for adjusting height (h
1) is provided together with a means for lengthening of the grips (25) comprising a
grip supporting base (30) allowing said grips (25) to slide by screwing and unscrewing
the screws (31).
[0013] Operation of the station (10) is as follows: when the cable (21) provided with the
rubber and the terminal (23) is arranged in front of the station, it is held by the
grips (17) of the gripping member (16) and the grips (25) of the gripping member (24)
close thereon, holding the cable (21) and the terminal (23). Then, the grips (17)
of the gripping member (16) are automatically opened to release the cable (21) and
then rotated to a given number of degrees by the actuator (26) in a circular movement
until the terminal (23) is arranged in the proper position. The terminal (23) is returned
to the gripping member (16) which arms (17) hold the cable (21) again so that it can
be placed inside the corresponding cavity of a conventional connector in next stations.
[0014] The amount of rotation degrees of the actuator (26) is a function of the number of
cavities in the connector, the type of connector and the features of the terminal
so that each terminal is allowed to enter the corresponding cavity in the proper position.
[0015] Once the invention has been sufficiently described in accordance to the enclosed
drawings, it is understood that any modification can be introduced as appropriate,
provided that variations may alter the essence of the invention as summarised in the
appended claims.
