DESCRIPTION OF THE PREFERRED EMBODIMENT
The invention relates to a snap-fit electrical connector for guiding and locating a tether connector. In its most general form, the electrical connector includes a base and a pair of tether guide flanges supported by the base. The end portion of each guide flange is configured to snap-fit into a mating recess or opening. In operation, the end portion of each guide flange snaps into a mating recess or opening formed in a fan bracket assembly for an automotive vehicle to secure the electrical connector assembly in position while the guide flanges help locate the tether in position.
FIG. 1
shows a perspective view of a snap-fit electrical connector assembly
10
formed in accordance with the teachings of this invention, and how the electrical connector assembly
10
could be located in a cooling fan bracket assembly
11
. The electrical connector assembly
10
includes a base
12
, a first pair of tether guide flanges
14
a, b
, a second pair of flanges
16
a, b,
and an electrical connector portion
18
.
Turning now to a detailed description of each element of the connector assembly
10
, the base
12
is an elongated member, which in one embodiment can extend substantially the entire length of the electrical connector assembly
10
. In the disclosed embodiment, the base
12
includes a planar rear surface
20
and a front surface
22
defining a semi-cylindrically shaped portion, best seen in FIG.
3
.
The front surface
22
of the base
12
, at one end, supports a cylindrically shaped guide
23
having an open center, and at the other end the base
12
defines a Y-shaped channel
24
. Adjacent the Y-shaped channel
24
, the base supports a pair of connector flanges
38
a, b,
one flange extending laterally outward from each side of the Y-shaped channel
24
and includes an opening therein for receiving a mechanical fastener such as a screw, pin screw or other similar device.
Turning now to the tether guide flanges
14
a, b
, each guide flange
14
a, b
includes a planar extension
26
that supports a flexible barbed end portion
28
. As best seen in
FIGS. 1 and 6
, the extension
26
of each flange
14
a, b
extends outwardly from opposing edges of the front surface
22
, and is flanked at its beginning and ending portion by a U-shaped groove
30
formed in the edge portion of the front surface
22
.
The electrical connector assembly
10
also includes a pair of dovetail flanges
16
a, b
that extend outwardly from the rear surface
20
of the base
12
. One of skill in the art will appreciate that other flange constructions can be used to perform the function of the flanges
16
a, b.
Each flange
16
a, b
includes a recessed planar dovetail shaped portion
39
. The opposing side edges of the dovetail shaped portion
39
support an L-shaped flange
40
, wherein the L-shaped flange
40
extends outwardly from the dovetail shaped portion
39
such that a portion of the L-shaped flange
40
extends outwardly from and is vertically offset from the dovetail shaped portion
39
.
As also shown in
FIG. 1
, the L-shaped flanges
40
of the respective flanges
16
a, b
extend in opposite directions, one projecting upward and the other downward. As shown in
FIG. 1
, the electrical connector assembly
10
also includes a pair of rectangularly shaped stops
32
and
34
positioned intermediate of the pair of dovetail flanges
16
a, b.
Turning now to the electrical connector portion
18
, the electrical connector portion
18
includes an elongated portion
44
having an open center
46
. A connector guide
48
is formed in the open center
46
and includes an upper plate
50
supporting a plurality of fingers
52
extending outwardly therefrom and a lower plate
54
defining a plurality of spaced apart ridges
56
positioned adjacent the fingers
52
.
The electrical connector portion
18
also includes a rear surface
42
substantially bounded by the Y-shaped end portion
24
of the base
12
. The rear surface
42
includes a plurality of openings
47
that permit access to the open center
46
.
The top surface of the electrical connector portion
18
supports an inclined surface
36
that extends upwardly and abuts the recessed surface
39
of the lower flange
16
b.
The bottom surface
59
of the connector portion
18
includes a pair of ridges
60
, which project axially along the entire length of the surface
59
. The bottom surface
59
also includes a second pair of axially extending guides
62
; however, the guides
62
extend along only a portion of the length of the surface
59
. Positioned intermediate the guides
62
is a tab
64
supported by a support plate
66
.
Installation and Operation
As best seen in
FIG. 1
, the connector assembly
10
is positioned in recess
68
formed in the fan bracket assembly
11
. The barbed end portions
28
of the pair of tether guide flanges
14
a, b
snap into mating openings
70
formed in the bracket
11
. The dovetail flanges
16
a, b
are received in a recessed portion
72
of the bracket
11
such that the L-shaped flange
40
of the respective flanges
16
a, b
, rests on the surface of the fan bracket
11
. The combination of the barbed end portions
28
and the dovetail flanges
16
a, b
in contact with the fan bracket assembly
11
may help to reduce the axial and lateral movement of the connector assembly
18
within the fan bracket assembly
11
.
Prior to coupling the snap-fit connector
10
to the bracket
11
, tether, cable or other electrical wiring is received in the cylindrically shaped guide
23
. The tether, cable or other electrical wiring is received in the channel portion of the front surface
22
, wherein the channel portion of the front surface
22
extends between the tether guide flanges
14
a, b
. The tether guide flanges
14
a, b
position the tether and help direct the tether, cable or other electrical wiring to be connector portion
18
, wherein desired electrical connections are established using conventional techniques.
