Binder designs plastic angled connectors with snap-in locking for tight spaces
Binder has addressed the vulnerabilities of plastic angled connectors with snap-in locking which are sensitive to faulty handling and developed the 720 miniature series of robust, field-attachable angled version for restricted installation conditions. An angled connector is now also available for the miniature NCC 770 series featuring variable direction of the cable outlet.
Field attachable angle variants complement Binder’s 720 and 770 product series. They are compact for use in device, building and plant engineering particularly where secure electrical connections need to be established in confined spaces. The angled versions of the 720/770 series with snap-in or bayonet locking provide a reliable and space-saving alternative to the straight versions.
The 720 snap-in series connectors have an electrical connection which is fixed mechanically by snap hooks in a slot, locking the interface. If, however, the connector is pulled off at an angle these hooks can be destroyed, depending on the amount and direction of the pulling force. The Binder design has a threaded ring inserted between the contact body and the angled housing. Even when force is applied at an angle to the connector axis, the snap hooks are protected against damage and the connectors can withstand loads far in excess of the standard requirements, said Binder.
Using the additional threaded ring, two further design requirements could be met. The concept enables binder to also offer the 770 series as an angle variant using many identical parts. The contact body can be rotated in steps of 90 degrees allowing the user for choosing the direction of cable outlet.
Cable routing is also problematic for housings angled at 90 degrees and bending the cable by 90 degrees is often difficult. Therefore, an angle of 100 degrees for the new housings simplifies cable assembly.
The new angled versions of the 720 snap-in series can be used in lighting technology installations, greenhouse heating systems and e-bikes. The series is specified for rated voltages from 60V to 250V and currents from 2A to 7A. For the three- to 12-pin interfaces, cable termination is achieved by soldering. The connectors comply with protection degree IP67 (mated) and can withstand more than 500 mating cycles.
NCC (Not Connected Closed) angled connectors of the 770 series with bayonet locking are used in compact handheld control panels, in medical homecare devices, and in laboratory metering instruments in space-constrained applications. The eight-pin interfaces are also equipped with solder terminals, rated voltage and current are 175V and 2A, respectively. In addition to IP67 when mated, the female panel mount connectors also achieve IP67 protection when unmated due to Binder’s NCC technology. The connectors withstand more than 5,000 mating cycles.
Connectors in both the 720 and 770 series are available in black, red, green and blue as well as in white (RAL 9002), which is typical for medical applications.
