7/22/2023 0 Comments Metal strain relief connectorIf the cable is inserted into a plug, this can lead to the cores being torn off the contacts in the long term.Ī cable duct with strain relief prevents this. If the bending radius is very small, the cable can even kink. The cable is then stretched over the outer radius and pulled out of the opening of the housing, the connector or the cable gland, while on the inner radius it is inserted and pushed in. A lot of cables are bent or even constantly moved back and forth. However, this is not the only reason why cables are exposed to mechanical stress and should be protected with strain relief. Everyone actually knows that you shouldn’t do this, as cables aren’t handles for holding onto. The Multi Cable fittings will meet Type NEMA 4x = IP65 if the design parameters are complied with.Strain relief is important for cables and hoses that are being tightened. The outside holes can be located right against the lip of the strain relief body, as sufficient insert material remains between the hole and the body wallĭesign Parameters: Cable diameter should not be less than 80% of hole diameter and the difference between hole and cable diameter should never exceed.Keep a minimum distance of 1 mm (.04 in) between holes.Drill holes with insert installed in Strain Relief Fitting as a fixture.Drill holes by using a standard high-speed steel drill bit of the proper size at approx.We suggest drilling the frozen solid insert.No Charge Manufacturing Fee - In 12-14 weeks or a one time Expedite Fee reducing manufacturing to 6-8 weeks.įor small quantities we suggest drilling or machining the inserts yourself.Any special insert hole or profile configuration is available for a minimum order of 1,000 pieces.Should be retained with a sealant such as Locktite® toĪvoid a loose connection when temperature fluctuates.

Torque in Inch Pounds - in lb (Newton Meters - Nm) The theoretical depth of the thread is therefore 0.64 times the nominal pitch.Threads are rounded equally at crests and roots by circular arcs ending.One-sixth of this sharp V is truncated at the top and the bottom.Symmetrical V-thread in which the angle between the flanks is 55°.Parallel (straight) thread with a constant diameter, denoted by the letter G.BSPP Thread = British Standard Pipe Parallel Thread.Depth of thread smaller than NPT or Metric, but larger flank angle.The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings.Designated by the letter M followed by the value of the nominal diameter and the pitch, both expressed in millimetres and separated by the multiplication sign '×' (i.e.Characterized by its major diameter and its pitch.World-wide most commonly used type thread Nylon Splines 6/6: V0 rated - Flame resistant, halogen and phosphorous free, self extinguishing, non-toxic, fungus resistant ![]()
