All numerical values are in metric units [with U.S. customary units in brackets]. Dimensions are in millimeters [and

inches]. Unless otherwise specified, dimensions have a tolerance of +

1. INTRODUCTION

This specification covers requirements for the application of Locking Clip 0.64--mm [.025--in.]

0.03 [+.001]) Square Contacts and Housings. The contacts are designed to mate with 0.64 [.025] square

posts with a maximum corner radius of 8.08 mm [.003 in.]. The contacts feature a locking lance, contact

spring, stabilizer, and wrap--around insulation barrel. The contact spring provides high contact--to--post

retention, while the locking lance holds the contact in the housing. The stabilizer maintains alignment of the

contact in the housing and the wrap--around insulation barrel is a feature which allows for wire with large

insulation diameters.

Housings are available in various sizes (number of contact cavities) with single-- and double--row contact

cavities on 2.54 mm [.100 in.] centerlines. Double--row housings are available in three configurations: both

ends closed, right end open, and left end open. Single--row housings are available only in both ends closed.

Right end open configurations are designed with a key and left end open configurations are designed with a

keyway. This design enables these housings to be stacked on the pc board for circuit grouping. Each contact

cavity in the housing features a cavity rib for contact polarization, and when loaded, the housings mate with the

posts. Each housing features an extraction slot which is used to remove individual contacts from the housing.

These requirements apply to hand and semi--automatic application tooling.

Figure 1 provides terminology for contact and housing features that will be used throughout this specification.

Use of these terms will facilitate assistance when corresponding with Tyco Electronics Representatives.

The dimensions must not exceed the limits shown in Figure 4. 7. Effective Crimp Length Effective crimp length is defined as that portion of the wire barrel, excluding bellmouth, which is fully formed by the crimping tool; it is shown in Figure 4.

Keying Plugs Keying plugs provide housing identification and polarization by not allowing a post to enter the contact cavity where the keying plug is installed. The latch must be oriented with the extraction slot cavity.

The wires must not be confined in any way that would restrict floating action of the contact in the housing. 1. Cable Ties The minimum distance for the cable tie, measured from the back of the housing to the first cable tie, is shown in Figure 10. 2.
