How to install soldersleeves

SolderSleeve provide electrical termination in a wide variety of interconnect applications.  One-step terminator capabilities include terminating wires to component terminals, ground wires to cable shields, terminating coaxial cable, and wire-to-wire splicing.


A precisely engineered, fluxed solder preform within the heat-shrinkable thermoplastic sleeve provides a completely soldered, strain-relieved, encapsulated termination.  The one-piece design of one-step terminators simplifies installation, while their transparent insulation sleeves make inspection easy.


This manual is for the wire-to-wire splicing only. I.e for the following products types:


Recommended Application Equipment

* Equivalent tools may be used.

Size Selection

Select correct part number from the SolderSleeve that matches the wire size.

Installation procedure

1. Wire Preparation

  •  Wires from up to 18 AWG [1.5mm2] having 19 or fewer strands: Remove 9.5mm of  insulation from all wires to be spliced.


  •  All other wires: Remove 12.5mm of insulation and pre-tin the exposed conductors with solder.




2. Assembly

2.1. Overlap the exposed conductors and position the one-step terminators so that the solder preform is centered over the conductors.

  • For a small gauge wires, (up to 1mm2), and when a mechanical attachment is required, secure the 2 wire ends, by twisting them together.  Align carefully the strands in order to avoid any poke through of the sleeve.  See Fig. 1 and Fig. 2.
  • In other cases, align wires in such a manner that all strands are parallel. Then, slide the sleeve over the splice area and center the solder preform of the sleeve at the center of the splice length.




2.2. The splicing operation is made easier by using the recommended holding fixture , keeping the wires aligned and the sleeve positioned during the termination.

2.3. Heat solder preform until it melts and forms a fillet between the conductors




3 Inspection

3.1.     Positioning: Wires stripped 9.5mm should overlap each other at least 6.0mm. On wires stripped 12mm the overlap should be 9.5mm

3.2.     Heating: The solder ring shape should not be visible and a solder fillet, at least 4.5mm long, should be visible on one side of the leads.  Fillet length should be 8.0mm for 12.5mm stripped wires.  Lack of solder fillet may indicate overheating.

3.3.     Damage: The sleeve should not be split or cut and no wire strands should poke through the sleeve.  Fillet length should be 8.0mm for 12.5mm stripped wires.
