1. INTRODUCTION
This specification covers the requirements for application of ELCON Drawer Series Connectors: True Hot Plug,
Blind Mating Mixed Signal and Power Connectors. These connectors are designed for use in pluggable wire-to-
board applications of power supplies. The connectors are available in a variety of custom configurations. The
pin side connector accepts pin contacts, and the socket side connector accepts socket contacts. The contact
cavities on both sides of the connector are marked for circuit identification.
The high power connectors are available with or without pre-installed guide pins; mid and low power connectors
are designed with molded-in guide posts to ensure positive mating of connectors. The molded-in pin protectors
prevent damage to the contacts. These features (including the guide pin holes and guide post cavities) have
chamfered edges for ease of mating. The connectors are designed for float-mount and fixed-mount applications
to allow blind mating with misalignment. All connectors are also designed with standoffs to allow easy printed
circuit (pc) board cleaning after soldering.
The contacts accept wire sizes 24 through 1/0 AWG. Contact sizes 20, 16, and 12 are available in crimp type,
and solder type terminations. In addition, contact size 12 is available in hot plug, specifically designed for
current interruption capability. Contact size 0 and 4 is available in crimp type termination, internal thread and
external thread for ring lug mounting and bus bar mounting. Pin contacts (except size 0 and 4) are available in
three lengths: standard, pre-mate, and post mate for flexibility in contact sequencing. The contacts contain an
active element, or crown band, which ensures maximum surface contact area, allows even insertion and
withdrawal forces, and provides shock and vibration resistance. The contacts are available in loose piece only.
Only crimp type and threaded contacts are removable.
When corresponding with TE Connectivity Personnel, use the terminology provided in this specification to
facilitate your inquiries for information. Basic terms and features of this product are provided in Figure 1.

Figure 2
Probe-proof socket contacts size 0 are designed with a protective cap to provide additional probe-proof
protection along with the crown band. This cap must not be removed from the contact. See Figure 3.
Some crimp type contacts feature a sight hole located on the side of the wire barrel or in the center of the inside
of the wire barrel. See Figure 3. Crimp contacts are rear-insertable and removable. PC board tail are rear-
insertable and non-removable.
The connector contact cavities contain retention clips. The retention clip is an important feature in holding the
crimped contact in the connector. When the contact is fully inserted, the retention clips engage the shoulder of
the contact and prevent backing out during mating of the connector.
3.5. Wire Selection and Preparation
The contacts will accept stranded wire sizes 24 through 1/0 AWG. Proper strip length is necessary to properly
insert the wire into the contact. The strip length of the wire is shown in Figure 4.
CAUTION
Reasonable care must be taken not to nick, scrape, or cut any strands during the stripping operation.

3.6. Crimp Type Contacts
Crimp contact to wire according to instructions packaged with applicable tooling. These requirements apply
equally to the pin contact and the socket contact.
A. Wire Barrel Crimp
The crimp applied to the wire barrel portion of the contact is the most compressed area and is most critical
in ensuring optimum electrical and mechanical performance of the crimped contact. The wire insulation must
not enter the contact wire barrel. The crimp height is controlled by proper use of MIL-DTL-22520 crimp
tooling. Refer to Section 5, TOOLING for tooling information.
CAUTION
Reasonable care must be taken not to cut or break the wire insulation during the crimping operation.
B. Tensile Strength
Crimped splices must hold the wire firmly and have a crimp pull-out test value meeting that specified in
Figure 5 (the test value is that of the smallest wire size used in the contact).
NOTE
Adjust tensile testing machine for head travel of 25.4 mm [1.0 in.] per minute. Directly and gradually apply force for one
minute.

NOTE
Each crimp dimension represents the functional range of wire and contact combination. The developed
crimp configuration is unique for each tool design and is acceptable provided the crimp height is within
the functional range. For crimp dimensions relating to a specific tool, refer to the instruction sheet
packaged with manual tools and the applicator log packaged with power tools.
C. Conductor Location
After crimping, the conductor ends must be flush to the end of the wire barrel. In contacts having a sight
hole, this can be verified by checking that the conductor ends are visible in the sight hole. See Figure 5.
D. Effective Crimp Length
The effective crimp length is the area where the crimp pressure is applied over the length of the wire barrel.
E. Straightness
After crimping the wire to the contact, the contact must be chucked, and rotated a minimum of 360°. The
point of TIR (total indicator reading) measurement must not exceed the dimensions shown in Figure 6.

3.7. Threaded Contacts and Guide Posts and Threaded Contacts
• Threaded guide posts should not exceed a torque limit of 1.7 Nm [15 in.-lb]
• Threaded contacts with M6 threading should not exceed a torque limit of 4.5 Nm [40 in.-lb]
• Threaded contacts with 1/4-20 threading should not exceed a torque limit of 6.8 Nm [60 in.-lb]
• Threaded contacts with M5 threading should not exceed a torque limit of 2.9 Nm [26 in-lb]
3.8. Connector Spacing
Care must be taken to avoid interference between adjacent connectors and/or other components. There is no
required spacing between connectors, however spacing may be dependent on variable hardware used and the
clearance required for mating connectors.
3.9. Panel Cutout
The pin side connector and socket side connector can be installed or removed from either the back or the front
of the panel (front of the panel is recommended). Usually, the socket side connector is mounted in the cabinet
(energized) panel, while the pin side connector is mounted in the drawer (passive) panel. Dimensions for
mounting holes, guide pins (if applicable), and panel cutouts, and maximum panel thickness for rear mounting
are shown in Figure 7.
3.10. Contact Insertion and Extraction
Normally an insertion tool is not required to insert contacts into connectors, but if the wire bundle is large or
individual wires are fragile, using an insertion tool is recommended. Push contact straight into the contact cavity
until it bottoms (an audible click). After inserting contact into connector, pull back lightly on the wire to ensure
contact is fully seated.
The contacts are rear-insertable and rear-releasable; an extraction tool is needed to disengage the connector
retention clips and remove the contact from the back of the connector. Only crimp type and threaded contacts
are removable. Refer to Section 5 for tooling information.
3.11. PC Board Connector
A. PC Board Material and Thickness
The pc board material shall be glass epoxy (FR-4 or G-10). The pc board thickness range shall be 1.38

C. Drying
When drying cleaned connector assemblies, make certain that the recommended temperature limitations of
-40 to +105°C [-40 to +221°F] are not exceeded. Excessive temperatures may cause housing degradation.
3.14. Connector Loading
These connectors provide optimum mapping of pin to function, and ease of routing in the system by accepting
various contact sizes, quantities, and types. All connector contact positions accept crimp type and solder type
terminations. In addition, high power connectors accept threaded contacts (size 0 only). Possible contact options
for loading individual connectors are shown in Figure 12.

3.15. Mounting Hardware
The connectors can be float mounted or fixed mounted to a backplane or chassis. The float mount shoulder
screws are designed to secure a connector to a panel. The panel must flex and be of sufficient gauge to support
mating loads. These screws allow some movement of the assembly for easier mating.
Connectors can be fixed mounted using commercially available screws with a head that will not interfere with
connector mating. Washers can also be used to make up the difference for the required hardware diameter. High
power connectors are fixed mounted using the mounting flange or, if available, the guide pins (which have
internal 6-32 threads). Hardware for specific connector types is shown in Figure 13.

3.16. Connector Mating and Alignment
The pre-installed guide pins and molded-in guide posts ensure positive mating of connectors. In addition,
because of their symmetrical design, the low power connectors have a polarizing feature: a rib in the guide post
cavity that fits into a notch in the guide post. When fully engaged, the dimension between the pin side
connector and socket side connector must be within the limit provided to ensure full mating. See Figure 14.
When mounted, the float mount design allows blind mating with gatherability up to 2.54 mm [.100 in.].
3.17. Special Assembly Consideration
The system into which the connectors are installed must support the weight of the drawer when connectors are
engaged (for example, the drawer must bottom on a built-in stop, not on the connector).
3.18. Strain Relief and Wire Dress
If required, wires can be bundled together and supported with cable ties. Wires must not be stretched or confined
in any way that would restrict the floating action of the connectors. Therefore, the wires must remain
perpendicular to the connector and avoid an excessively sharp bend radius. The minimum distance for the cable
tie, measured from the wire end of the connector to the cable tie, and the minimum bend radius of a wire bundle
is shown in Figure 15.

3.19. Repair
Damaged connectors must be removed, discarded, and replaced. Connectors with solder type contacts will
require desoldering of all contact solder tails. Solder type contacts are not removable from the housing
assembly.
Damaged crimp type contacts must be removed from the connector, discarded, and replaced with new ones.
CAUTION
Damaged product should not be used. If a damaged contact is evident before the contact is inserted into the housing, cut the wire
in back of the contact and re-terminate the wire end. If contact is damaged after insertion, remove the contact with the extraction
tool and cut the wire in back of the contact and re-terminate wire end.
4. QUALIFICATIONS
ELCON Drawer Series Connectors and Contacts are Recognized by Underwriters Laboratories Inc. (UL)/CSA
International in File E28476.
5. TOOLING
Hand and pneumatic crimping tools that accommodate the full wire size range are designed for terminating
crimp type contacts. The insertion/extraction tools are designed to insert and remove crimp type and threaded
contacts from connectors. The tool depresses the connector internal retention clips without deforming them.
Tooling part numbers and instructional material packaged with the tooling are shown in Figure 16.
NOTE
Military standard Daniels bench mount crimping machine is applicable for terminating crimp type contacts. This machine has been
designed to form indents to the proper depth in the contact wire barrel. It requires a specially designed funnel which helps gather
wire strands and guide them into the closed barrel of the contacts. It is designed for production requirements. Refer to Figure 16.
