Heat shrink butt connector for VHF speaker?

[SAWDOC]

I wish to connect an external speaker to my VHF. It is a simple two strand cable connection. I appreciate that the integrity of these connections are very significant for clear reception. I have used an chocolate box connector to get the system up and running but I now want to get it as good as posible. Would a heat shrink butt connector be best practice or any other suggestions. )ne of the wires to be connected is the shield and core type.

Thanks for any suggestions.

With connections like that I normally stagger the connections by a half inch. Solder the connections. A bit of self amalgamating tape round each then tape over the whole thing. There are several scattered around the boat and I've never had one fail yet.

Stagger the joints as has been said, but I would use heat shrink butt connectors, and then a piece of heat shrink sleeving over both. Mind you if you want to remove them ever, its going to be a job and a half!

thanks for your reply. what is the thinking behind staggering the connection? does it make it more robust?

Makes it less bulky.

As PRV says, less bulky but also, if soldering, less liklihood of me getting the insulation wrong and creating a short.

As one of the cables is a shield and core and if it’s in a protected area you could consider in line three pole gold plated 2.5mm jacks (not as expensive as the name suggests) I have used these a few times on speaker and NMEA 0183 extensions and found them very effective and easy to use, if there is any concern about them parting then cover the assembly with some non adhesive lined heat shrink, that way they are easy to disconnect at a later date.

Now that is a bloody good idea! Must remember that one and buy some from maplins whilst in UK.

Err, dont want to go round in circles here but how best to connect to jack and socket??? A case of see above?

 

[David2452]

Just connect three conductors to the jack, the other three to the socket and plug it together, if you have three conductors then use a three pole jack, if four then use a four pole. If what you are asking is how do I connect cables to an inline jack then there are places on tinterweb with detailed step by step instructions I'm sure.

Here's just one.

thanks to all for excellent information and a nice range of solutions - just what I was after!
I'm going to set up a little practice circuit at home and improve my crimping and soldering technique.
Thanks again.
