Grommet & Strain Relief Solutions
Molded On and Slip On Products

We provide standard and custom molded grommets, strain reliefs and cable grip products to the cable assembly and OEM market. These molded strain relief products are available with over 1,500,000 different configurations with no tooling cost required. Minimum order quantities are as low as 100 pc for standard off the shelf parts, and 250 pc minimum for build to order molded strain reliefs.. Molded cable assembly and strain relief assemblies are an important part of an interconnect product, and designing in the correct strain relief, whether molded on or as a slip-on discrete part is an integral part of the overall products performance.

Strain relief in an interconnect component can be defined as internal stress relief at the termination point or flex relief at the cable exit area. Internal to a connector or termination point, such as a breakout transition, is the point at which the wires are terminated to contacts or other wires. Many devices require the addition of strain relief in this critical area. Many connectors provide this in the connector design itself, such as the insulation support area of a contact and the wire bar clips used on insulation displacement connectors. However, other devices, because of other mechanical considerations, require additional strain relief. Overmolding the contact and wire termination area can improve the pull-force performance, typically by a factor of two to three times. It is common for 40-60# pull-force to be achieved by simply overmolding. Molded strain reliefs, also commonly referred to as molded cable grips may be the answer.

The point at which a cable exits a connector body or other component can be a critical failure point because of repeated flexing. Typically, flex life of the cable can be improved up to four times the manufacturer's rating by incorporating an overmolded flex relief. Molded cable grips are common in devices that have high flex rates, such as point-of-sale scanners and medical devices.
