Electrical connector with removable external load bar, and method of its use

1. A method of using a hollow electrical connector housing having a front end wall with an external integrally thickened wall portion, comprising the steps of: forming a plurality of holes through the thickened wall portion; feeding a plurality of wires through respectively corresponding holes; and then shearing off the thickened wall portion together with the wires contained therein.

2. The method of claim 1 wherein the holes are formed in an upper horizontal row and a lower horizontal row, the wires in the upper row are sheared off first, and then the wires in the lower row are sheared off.

3. In an electrical connector, an elongated hollow housing having a generally continuous forward end wall with upper and lower surface areas, the lowermost surface area having an integrally thickened outer portion which is adapted to be sheared off to make the connector operable, and wherein the thickened wall portion has a plurality of openings through which wires placed inside the housing may project outward beyond its forward end wall.

4. A connector as in claim 3 wherein the upper surface of the forward end wall has a plurality of slots formed therein for receiving contact blades of a mating connector.

5. A connector housing as in claim 3 wherein the openings include an upper row of openings and a lower row of openings, and the thickened wall portion has a measurable amount of plastic material beneath the lower row of openings.

6. A method of preparing an electrical connector, comprising the steps of:

selecting an elongated hollow plastic housing having an open rearward end and an essentially continuous forward end wall, a lower portion of the forward surface of the forward end wall being integrally thickened, the upper portion of the forward end wall having slots for receiving contact blades of a mating connector;

creating a set of openings through the forward end wall including its thickened lower portion;

inserting a plurality of wires into the open rearward end of the housing and forcing them into and through corresponding ones of the set of openings in the forward end wall so that they project forwardly beyond the forward end wall; and

then shearing off the thickened portion of the forward end wall and concurrently with it the projecting ends of the wires, so that the cut-off bare end faces of the wires are flush with the then remaining forward end wall surface of the housing, and the wire ends are securely held in place within the respective holes.

7. The method of claim 6 wherein two parallel rows of openings are formed in the forward end wall, an upper row and a lower row.

8. The method of claim 7 wherein the openings in the upper row are larger than the openings in the lower row.

9. The method of claim 6 wherein the wires are electrically insulated.

10. The method of claim 6 wherein a plurality of slots are formed in the upper surface of the front end wall for receiving the contact blades of a mating connector, and wherein the plastic housing is mechanically supported while the thickened wall portion and protruding wires are being sheared off, so as to preserve the dimensional stability of the upper portion of the forward end wall and the slots therein.

11. In an electrical connector, an elongated hollow housing having a generally continuous forward end wall with upper and lower surface areas, the upper surface of the forward end wall having a defined plane and having a plurality of slots formed therein for receiving contact blades of a mating connector, and the lowermost surface area of the wall having an integrally thickened outer portion which is adapted to be sheared off in the defined plane of the upper surface area so as to avoid deforming the upper surface of the forward end wall.

12. An electrical connector as in claim 11 wherein a plurality of holes are formed in the thickened lowermost surface of the wall.

13. An electrical connector as in claim 12 wherein the holes are formed in two horizontal rows, an upper row and a lower row.

14. An electrical connector as in claim 13 wherein the holes in the upper row are of larger diameter than those in the lower row.

15. An electrical connector as in claim 13 wherein the holes in the two rows are in staggered relationship.

16. An electrical connector as in claim 13 wherein the holes of the two rows are partially merged together.
