Abstract

An electric connector (1) comprises, an insulating housing (3), and contacts (7) in respective contact receiving cavities (8). The contacts (7) have respective marker surfaces (18) that align with respect to marker surfaces (21, 23) located in the staggered positions on the housing (3) to position at least one of the contacts (7) farther from a mating end (2) of the housing (3) than another of the contacts (7 ). The contacts (7) are to be inserted by engaging a straight surface of an insertion tool against their marker surfaces (18) and then impelling them along the cavities (8) until the marker surfaces (18) are aligned with respect to selected one or the other of the marker surfaces (21,23). The marker surfaces (21,23) can also serve to limit travel of the insertion tool. The contacts after such insertion are positioned in staggered rows and are retained by engagement of barbs (17) with walls of the cavities.

Claims

1. An electrical connector comprising:

multiple electrical contacts extending axially along respective contact receiving cavities in an insulating housing upon insertion of said contacts thereinto from an insertion face toward a mating end of the housing, wherein at least two transverse marker surfaces on the housing are positioned at different depths along an axis of the housing and exposed to said insertion face to be engageable by insertion tooling to limit travel thereof during contact insertion, and wherein each of said electrical contacts is provided with at least one respective tool-engageable transverse marker surface that is, upon contact insertion, in coplanar nonabutting relationship with respect to selected one of the housing marker surfaces depending upon the desired depth of insertion of the contact into the housing.

2. An electrical connector as recited in claim 1 wherein at least one of the contacts is in a forward position with said marker surface thereof in alignment with respect to a forward marker surface on the housing.

3. An electrical connector as recited in claim 1 wherein at least one of the contacts is in a rearward position with said marker surface thereof on said one of the contacts in alignment with respect to a rearward marker surface on the housing.

4. An electrical connector as recited in claim 1 wherein the contact receiving cavities are identical and thereby are adapted to receive the electrical contacts to different insertion depths interchangeably in respective cavities.

5. An electrical connector as recited in claim 1 wherein the marker surfaces on the housing are adjacent respective contact receiving cavities in the housing, and the contacts are received in respective cavities.

6. An electrical connector as recited in claim 1 wherein at least one of the contacts is spaced farther from a mating end of the housing than at least one other contact of identical shape and mass.

7. An electrical connector as recited in claim 1, wherein either one of the contact receiving cavities is adapted to receive identical contacts equally spaced from the mating end of the housing.
