Question Need to Identify Antenna Connector

[SolarPV]

I need help to identify the following non-standard push connector that is used to plug in a cable linking to a standard SMA-type Wi-Fi Antenna.

The connector I need to identify and purchase looks like this:

It plugs in to this receiving pin:

I tried to take measurements as best as possible,

• The connector outer diameter is approx. 6.3 mm and 7 mm deep
• The receiver outer diameter is approx. 4.4 mm, inner diameter 2 mm, and signal pin 1 mm

Can anyone identify this model of connector and suggest a vendor to purchase from?

Thanks in advance!!

Looks like smb but it could be some proprietary thing if these are for wifi antenna.
