Manufacturing and Technical Details


Most frequent questions and answers

The K Series Push Pull Waterproof connectors are heavy-duty and outdoor-rated electrical connectors that are able to provide you a very strong push pull connection between male plug and female receptacle.

K Series Push Pull Waterproof connectors consist of a male plug and female receptacle connected together with a powerful self-latching system that can be released only by making a small force on the outer release sleeve backward.

You can easily solder the end of one wire with the male plug’s insulator and the end of the other wire with the female receptacle.

After that, they can be connected by a simple push of the plug contacts into the receptacle.

This strong and efficient connection prevents every accidental disconnect.

Every K Series Waterproof connector manufacturer has its own terms and conditions for testing samples for their customers.

You have to search on the web for different K Series Push Pull Waterproof connector manufacturers that can provide you a free testing sample of their products.

However, you can contact the Shenzhen INTE-AUTO Technology Co., LTD in China that can provide you a free sample of K Series Push Pull Waterproof connectors.

You can get a sample of the connector within one to three days when INTE-AUTO has received your sample request.

The K Series Waterproof connectors are very easy to operate. You must follow the steps below:

  • First of all, the wire should be solder with the insulator’s contacts of the plug.
  • The split insert carrier, along with the insulator, is then inserted into the plug’s outer shell.
  • The female socket / receptacle should then be mounted on the panel of the device either through PCB contacts or by soldering. The choice depends on the design of your device.
  • As a customized solution, you can also utilize crimp connections.
  • Now you have to insert the male plug inside the female socket / receptacle.
  • K Series Waterproof connectors have a very strong and powerful self-latching system to lock the connection between receptacle and plug.
  • When you insert the plug into the receptacle, the sleeve latching system inside the plug retracts.
  • The arrow type end of the latches slides inside the surface of the receptacle smoothly as far as it reaches an area that has the same shape as that of the latches end.
  • At this stage, you have closed the circuit, i.e., your data, current, or signals are now starts transferring between the plug wire and the receptacle panel.
  • When the plug and receptacle are mated, they cannot be unmated because of the self-latching system designed in them.
    So for removing the locked connection, you should softly push back the K Series Waterproof connector’s outer release shell.
    When you push back the outer release shell, the latches in the plug retract, and the arrow type end of the latches removes from the receptacle.
    That allows you to easily disconnect the plug and receptacle.


When K Series Waterproof connectors are mated, a strong bond / connection exists due to a self-latching system designed between plug and receptacle.

The connection never breaks by stretching the cable from both sides or pulling any other connector component.

This strong connection can only release / unmated if you push the outer release shell of the plug backward.

By pushing the outer release shell backward, the latches in the plug retract, and its arrow type end removes from the receptacle, allowing you to disconnect the plug and receptacle easily.
