Strain Relief's and Grommets
Molded On and Slip On Solutions
We provide standard and custom molded strain reliefs and molded 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
100pc for standard off the shelf parts, and 250pc 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.
