ELECTRICAL TERMINAL
Abstract
A detachable flag-type terminal which may be stacked on a post
is disclosed. The terminal is generally U-shaped in cross section.
The web is extended and arched rearwardly to form a spring means
which acts as a post-holding means. Openings are formed in the
sidewalls of the web. The openings are formed in the sidewalls of
the web. The openings are aligned thereby creating a passage
through which a post may be inserted in a direction normal to the
axis of the ferrule of the terminal.

Claims
I claim:
1. An electrical terminal comprising a conductor-engaging section
for engagement with a wire conductor and defining a first
longitudinal axis, a contact section for engagement with an
electrically conductive post, said contact section having a floor
and sidewalls which define a second longitudinal axis parallel to
said first axis, said sidewalls having aligned openings therein
adjacent said floor for receiving said post therethrough, said
openings defining a third axis transverse to said second axis, and
an extension of said floor extending outwardly from a front end
thereof and being bent back over said floor with a free end
disposed between said aligned openings and intersecting said third
axis, said extension defining a spring means for engaging and
biasing said post.
2. An electrical terminal according to claim 1 wherein said
openings have a configuration conforming to that of said post.
3. An electrical terminal according to claim 1 wherein said spring
means engages and biases the post against said floor.
4. An electrical terminal comprising a conductor-engaging section
for engagement with a wire conductor and defining a first
longitudinal axis, a contact section for engagement with an
elongated electrically conductive member, said contact section
having a floor and sidewalls which define a second longitudinal
axis parallel to said first axis, said sidewalls having aligned
openings therein for receiving the elongated electrically
conductive member therethrough, said openings defining a third axis
transverse to said second axis, and an extension of said floor
extending outwardly from a front end thereof and being bent back
over said floor and intersecting said third axis to define a spring
means for engaging and biasing said elongated electrically
conductive member away from said floor.
Description
The present invention relates to electrical connectors of the type
used to connect a wire to a post and more particularly to a
detachable flag-type terminal which may be stacked onto a post.
It is an object of this invention to provide an improved terminal
for making flag-type connections.
Another object is the provision of an electrical terminal having a
contact section provided with aligned openings through which a post
extends and spring means to maintain the terminal in position on
the post.
An additional object is to provide an electrical terminal having a
U-shaped contact section in which a post is disposed in engagement
with a floor portion thereof by a spring means which is part of the
floor portion.
It is a further object to provide a flag terminal which can be
manufactured with relative ease and which does not involve close
manufacturing tolerances.
Other objects and attainments of the present invention will become
apparent to those skilled in the art upon a reading of the
following detailed description when taken in conjunction with the
drawings in which there is shown and described an illustrative
embodiment of the invention; it is to be understood, however, that
this embodiment is not intended to be exhaustive nor limiting of
the invention but is given for purposes of illustration and
principles thereof and the manner of applying it in practical use
so that they may modify in various forms, each as may be best
suited to the conditions of a particular use.
These and other objects are achieved in one embodiment in which the
terminal is generally U-shaped in cross section. The web or floor
is extended and arched back over that part of the web enclosed by
sidewalls thereby creating a spring means. In each parallel
sidewall there is an opening which may either be enclosed by the
sidewall thereby creating an enclosed hole in the sidewall, or
partially enclosed by the sidewall thereby creating a slot in the
sidewall. The openings in the sidewalls are aligned thereby
creating an opening through which a post may be inserted in a
direction normal to the axis of the ferrule of the terminal. The
spring means is arched over the portion of web enclosed by
sidewalls such that the end of the spring means is adjacent the
openings in the sidewalls, the end of the spring means is spaced
from the web or floor a distance which is less than the thickness
of the post to be inserted.
The insertion of the post causes deformation in the spring means
thereby creating a constant force on the post and causing the
terminal to remain in position on the post. Several terminals may
be placed on the post by simply inserting the post through the
openings of the required number of terminals.
In the drawings:
FIG. 1 is a top plan view of the terminal in accordance with the
invention;
FIG. 2 is a side elevational view of FIG. 1; and
FIG. 3 is an exploded perspective view showing a post and its path
of insertion into the terminal.
A terminal T, in accordance with the present invention, is of
substantially U-shape cross section throughout and comprises a
contact section 1 and a ferrule or conductor-engaging section 2.
Contact section 1 comprises a floor or web 3 which includes an
extension 4 arched back over a portion of web 1 and contained
within parallel sidewalls 5 thereby forming a spring means. Spring
means 4 is substantially the same width as web 1 and is arched back
to form a substantially smooth arch so that its free end 4a
terminates a short distance from web 3.
Each sidewall 5 contains opening 6; these openings being in
alignment. The aligned openings 6 as shown in FIGS. 1, 2 and 3 are
for illustrative purposes only and in no way limits other possible
opening configurations including those which would create a slot in
the sidewalls by being only partially enclosed thereby. Ferrule
section 2 includes a serrated wire-engaging member 6 and an
insulation-engaging member 7 which is attached to a feed strip
8.
The centerline of the aligned openings is perpendicular to the
longitudinal terminal axis such that post 9 may be inserted normal
to this axis as shown in FIG. 3. Openings 6 are larger than post 9
to allow free passage of the post through the openings. Spring
means 4 is aligned such that free end 4a is disposed about midway
of the height of openings 6 as illustrated in FIG. 2.
When post 9 is inserted into openings 6, it is engaged by free end
4a and spring means 4 is deformed upwardly or outwardly thereby
creating a constant force to be exerted on post 9 at the point of
contact therewith to thereby force the post into engagement with
web 3 which provides adequate area contact therebetween. Post 9 is
provided with a beveled end to facilitate engagement with end 4a of
the spring means.
Openings 6 are larger than post 9. This coupled with spring means 4
is an advantage because exact tolerances are not necessary. The
spring means compensates if the post is smaller or larger than the
established mean value.
A particular advantage of the invention is that the openings and
the post have a mateable configuration, e.g. rectangular, to
prevent the terminals being rotated about the post. Of course, a
round post can be inserted in the rectangular openings without the
antirotation feature.
Changes in construction will occur to those skilled in the art and
various apparently different modifications and embodiments may be
made without departing from the scope of the invention. The matter
set forth in the foregoing description and accompanying drawings is
offered by way of illustration only.
