Manufacturing and Technical Details


Most frequent questions and answers

INTE-AUTO Self-Locking Connector is a small bridge between two devices that takes responsibility for data, current, signals or fluid transmission from one device to the other.

It consists of two main external parts called a socket and a plug.

The device or cable where you need to send data, signals or current is connected to the socket.

The plug is connected with the device or cable from where you need to receive data or current for transmission.

The term ‘’self-locking’’ in INTE-AUTO Self-Locking Connectors clearly means that you do not need to apply much effort and time to lock and unlock these connectors.

It is because there is a strong self-latching mechanism installed in the plug and socket in order to complete the locking and unlocking process.

Nowadays, this mechanism is in great demand for all applications where connectors are used for data and current transmission.

You can get straight or elbow configurations of these connectors with a facility of solder, PCB or crimp contacts.

INTE-AUTO Self-Locking Connectors follow a simple rule for mating and un-mating.

The mating and un-mating totally depend on the self-latching mechanism installed into these connectors.

When you need to mate the plug and socket, you need to push the plug into the socket such that all the plug contacts enter into the socket holes.

During mating, the following process occurs:

  • The self-latching mechanism consists of two half arrowhead shape latches inside the connector’s plug.
  • When you push the plug into the socket, the latches inside the plug retract with the outer shell walls.
  • There is a space inside the socket similar to the shape of the plug’s half arrowhead latches.
  • When the plug’s latches reach that socket half arrowhead shape space, the arrowheads quickly lock or fit into that space.
  • The plug and socket are now strongly mated, and your data, current, signals or fluid can be easily transferred from one device to the other.
  • To un-mate the connection, the outer shell of the plug should be pushed in the backward direction.
  • Doing this will release the plug’s half arrowhead shape latches from the socket grooves, and the plug can then easily be removed from the socket.

Yes, INTE-AUTO Self-Locking Connectors can easily and strongly defend accidental cable tugs.

The self-latching mechanism in these connectors does not allow the plug and socket to disconnect even in harsh conditions.

You can only break the connection if you push back the outer shell of the plug.
