Description




FIELD OF THE INVENTION




This invention relates to electrical connectors and more particularly to a clip for attaching an electrical connector to the edge of a panel.




BACKGROUND OF THE INVENTION




Automotive vehicle wiring is made up of a number of wiring harnesses that are connected to each other with electrical connectors that include plastic connector bodies that hold electrical terminals attached to the ends of electrical leads. These electrical connectors are often attached to a panel edge in the vehicle body by a connector edge clip to route the wiring within the vehicle body.




The thickness of the panel edges in the vehicle body that the connector edge clips are attached to varies. This results in the use of a different connector edge clip for each panel edge thickness found in a particular vehicle body. Sometimes a particular connector edge clip can be used for a small range of panel edge thicknesses. However, even then several connector edge clips are required resulting in a proliferation of parts and increased assembly costs. Consequently there is a need for a connector edge clip that can be attached to panel edges that vary in thickness with a wide range.




During vehicle build, it is also often necessary to detach the connector edge clip from the panel edge, mate the electrical connector with the electrical connector of another wiring harness and then reattach the connector edge clip to the panel edge. Consequently there is also a need for a removable connector edge clip that not only holds the electrical connector on to the panel edge firmly but also one that is detached and reattached to the panel edge easily.




SUMMARY OF THE INVENTION




This invention provides a removable connector edge clip that can be attached to panel edges that vary in thickness within a wide range and that holds an electrical connector on the panel edge firmly while facilitating detachment and reattachment of the connector edge clip to the panel edge.




The removable connector edge clip of the invention has a clamp that can be slid on any panel edge within a wide range of thicknesses, for instance from 1 mm to 4 mm, and held firmly on the panel edge by spring blades and barbs inside the clamp. The connector edge clip includes a connector attachment for an electrical connector and is configured so that the connector edge clip can be removed from the panel edge easily by applying pressure to the electrical connector. The connector edge clip is also preferably equipped with an anti-tangle tongue that prevents the connector edge clips from tangling up with each other during the manufacturing process. The spring blades inside the clamp also preferably provide an anti-tangle feature.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT




Referring now to the drawing, a removable connector edge clip


10


of the invention is illustrated. Edge clip


10


which is preferably made of spring tempered steel is generally S-shaped comprising a support plate


12


, a first arm


14


and a second arm


16


. The first arm


14


is integrally attached to a first end of support plate


12


by a first bight so that first arm


14


is spaced below support plate


12


. When so attached, first arm


14


confronts a lower surface of support plate


12


in generally parallel fashion to form a panel edge clamp


18


at the first end of clip


10


.




Support plate


12


has two laterally spaced spring blades


20


that are cut out of the sheet metal body of the support plate


12


and inclined downwardly toward first arm


14


and the first bight that attaches first arm


14


to support plate


12


.




Spring blades


20


are attached to support plate


12


outwardly of the panel edge clamp


18


and project into panel edge clamp


18


as best shown in FIG.


4


. Spring blades


20


biasingly engage a panel edge


21


that is inserted into the panel edge clamp


18


as best shown in FIG.


1


. First arm


14


has a barb


23


at each side edge that digs into panel edge


21


to retain the removable connector edge clip


10


on panel edge


21


after it is inserted into panel edge clamp


18


.




The second arm


16


is integrally attached to the second opposite end of support plate


12


by a second bight so that second arm


16


is spaced above support plate


12


. When so attached, second arm


16


confronts an upper surface of support plate


12


in generally parallel fashion to form a connector attachment


22


at the second opposite end of clip


10


. Connector attachment


22


operates independently of support plate


12


. It has a wider portion


24


adjacent the second bight that attaches second arm


16


to support plate


12


and a narrower portion


26


at the free end so that wider portion


24


forms stop shoulders


28


as best shown in FIG.


2


. Second arm


16


includes a medial detent tang


30


and two laterally spaced second spring blades


32


that are formed out of the sheet metal at the respective edges of the narrower portion


26


of second arm


16


. Spring blades


32


are inclined downwardly toward support plate


12


and the second bight that attaches second arm


16


to support plate


12


. Detent tang


30


is inclined upwardly toward the second bight and away from the second arm


16


.




Support plate


12


preferably includes a medial anti-tangle tongue


34


that is cut out of the sheet metal of support plate


12


and inclined upwardly toward the second bight and the second arm


16


. Tongue


34


does not cooperate in the mechanical attachment of an electrical connector


36


to the connector attachment


22


which relies on the stop shoulders


28


, detent tang


30


and spring blades


32


. The function of tongue


34


is to prevent loose connector edge clips


10


from tangling with each other during the manufacturing process, shipment and handling.




Referring now to

FIGS. 1 and 3

, removable connector edge clip


10


operates as follows. Clip


10


is installed on panel edge


21


by inserting panel edge


21


into panel edge clamp


18


against the bias of spring arms


20


. When fully inserted, spring blades


20


-push panel edge


21


down against arm


14


where barbs


23


dig into panel edge


21


to prevent removal of clip


10


. Clip


10


, however, may be removed with the assistance of electrical connector


36


as explained below. In any event, panel edge clamp


18


accommodates panel edge within a range of thicknesses due to the presence of spring blades


20


. For instance we have found that a removable connector edge clip of our invention can be firmly attached to panel edges that varied from 1 mm to 4 mm.




After removable connector edge clip


10


is installed, electrical connector


36


is pushed onto connector attachment


22


. Clip


10


is an S-shape configuration so that electrical connector


22


is pushed onto connector attachment


22


in the same direction as clip


10


is pushed onto panel edge


21


. Thus the electrical connector installation does not disturb the clip installation on panel edge


21


and in fact tends to enhance the clip installation. Connector


36


is pushed onto the narrower end portion


26


until stop shoulders


28


are engaged. When installed, detent tang


30


engages an internal shoulder of electrical connector


36


to prevent pull-off as best shown in FIG.


1


. Spring blades


32


also biasingly engage internal longitudinal surfaces of electrical connector


36


to attach the electrical connector


36


to clip


10


firmly. After complete installation, electrical connector


36


can be removed by depressing detent tang


30


(with suitable tools that are well known) and pulling electrical connector


36


off connector attachment


22


. This is a tedious and time-consuming job. However, connector edge clip


10


with electrical connector


36


still attached can be removed from panel edge


21


easily with assistance of the attached electrical connector


36


by pressing down on connector


36


aft of second arm


16


as indicated by arrow A in FIG.


1


. This exerts a clockwise movement on clamp


18


that opens clamp


18


and reduces the clamping force of spring arms


20


as well as the grip of barbs


23


. Downward force applied to electrical connector


36


aft of arm


16


thus facilitates removal of connector edge clip


10


from panel edge


21


.




Electrical connector


36


may be mated to the electrical connector of another wiring harness after which connector edge clip


10


is simply reattached to panel edge


21


by sliding clamp


18


onto the panel edge.




Clip


10


with connector attachment


22


is designed for use with electrical connectors having a clip attachment comprising an open slot with sidetracks such as illustrated with electrical connector


36


. This configuration allows a maximum anti tangle tongue


34


that does not interfere with installation of the electrical connector


36


onto connector attachment


22


. However, electrical connectors with a closed clip attachment slot can be used. In this case, the interference can be tolerated and/or the anti tangle tongue


34


can be shortened.
