1. INTRODUCTION

This specification covers the requirements for 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.

When corresponding with TE Connectivity Personnel, use the terminology provided in this specification to

facilitate inquiries for information. Basic terms and features of this product are provided in Figure 1.

Wire Barrel Flash Wire barrel flash is the formation that may appear on both sides of the wire barrel as the result of the crimping process. It must not exceed the limit shown in Figure 4. 6. Bellmouth The front and rear bellmouths result from the protrusion of the metal of the wire barrel after the crimping process.
