The PUSH-PULL connectors can quickly complete stable connection and disconnection of electrical and signal circuits in limited installation spaces, and effectively achieve high-precision signal transmission, power supply and anti-interference shielding protection for various precision equipment. In this article, the relevant knowledge of PUSH-PULL connector will be introduce. I hope it will help a little to whom are looking for the suitable connectors for your project.
The definition of the PUSH-PULL connectors.
How do PUSH-PULL connectors differ from other connectors?
How to chooose the right type for your project or customize?
QM Connectors have
Push-pull self-locking connectors are circular connectors that achieve connection and disconnection via an internal spring-locking mechanism. Their key feature is "lock with one push, release with one pull". Requiring no external accessories such as threads or latches, they enable single-handed mating and unmating, combining convenience with high reliability. They are widely used in military, medical, semiconductor and other fields with stringent stability requirements.
A connector mainly consists of a plug and a socket. When mated, they enable the transmission of signals, power, etc. Structurally, they comprise a housing, an insulator, and contact pins, sometimes supplemented with cable clamps, strain relief boots, and other components. The figure below shows an exploded view of the plug and socket respectively.
Unlike threaded connectors that require twisting or bayonet connectors that need manual latching, push-pull self-locking connectors only take two steps: "push to lock, pull to unlock". They can be fully operated single-handedly in under 2 seconds, improving efficiency by over 80%. This makes them ideal for medical devices and test instruments requiring frequent mating cycles. Additionally, the audible "click" provides positive confirmation of a secure connection, eliminating the risk of poor contact.
The internal embedded locking mechanism and precision keying design deliver excellent vibration and shock resistance, preventing accidental disconnection even in high-vibration environments such as military vehicles and industrial equipment. Furthermore, they support high ingress protection ratings of IP67/IP68 and a wide operating temperature range (-55°C to 200°C), ensuring stable signal transmission in harsh conditions including humidity, extreme temperatures, and dust.
Featuring gold-plated contacts and high-precision metal housings, these connectors offer a mating life of 5,000 to 10,000 cycles, far exceeding standard connectors. Low contact resistance and high shielding performance guarantee lossless transmission of signals and power, meeting the stringent precision requirements of semiconductor and medical equipment.
The compact circular form factor, combined with no external latches, minimizes space occupancy, making them suitable for tight installation spaces in miniature instruments and portable devices. They also support blind-mating operation, enabling precise connection even in visually obstructed environments.
