Don't buy banana plug from this site

[GaryY]

My 10 AWG speaker cables (gearIT) are too stiff and I ordered some plugs and sleeve from Ali. Before plugging in cable, I measured open short what I usually don't do, but 6 plugs out of 8 were not conductive. It looks inner pin for giving pressure is not contacting front insert or (looking) gold plating is not well done. And.....at least Front insert part is PLASTIC... It was not plasitc. But still no contact from climping screw part to insert.

Edit :
This case may not be in general and, to avoid unfair reputation to the similar product from other manufacturer, I add the link of this product.
Also title is editted.

And here is the simple test.

why?
I could see some reason behind buying electronics from china (would not do it anyway), but audio connectors?

The original ones from WBT are expensive, but they are great.

I've bought a crimping tool since.

Yeh...it was mistake, but slightly cheaper and I had lots of time to wait.

I was stupid just looking at the price.

I'd amend the thread title to don't use banana plugs. Never liked them. Prefer spades myself. Or bare wire tinned on the end.

What's wrong with banana plugs? I think they are much easier to use than spades. With spades you have to hold the cable in place while you tighten the connector. With bananas, just shove it in and you're done.

Some don't hold the wire tight or loosen over time. Don't like that they give leverage on the jack if you are using large cables. An extra connection to worry about. I've had small little issues with those while with spades no such issues. If you plug and unplug them they are handy. I replaced them on my Quad ESL 63s with some sturdy copper binding posts. Now I'm not saying it is a big or common issue with most of them, but it is one issue you can avoid altogether. Spades are more trouble to connect, and sometimes their positioning by speaker makers does us no favors. But after they are on they are good. Maybe speak-ons are better than all of them.

I have all 3 types of connectors - spades, banana plugs, and Speakons. I love the Speakons, but they have a serious disadvantage - AFAIK there are no right angle connectors. Spades come only in right angle (might be a disadvantage), and banana plugs can be either right angle or straight. This means that extra room is required for Speakon connectors, which may or may not be an issue.

SAPT53 - Right Angle Speakon Cable Connector - 2 or 4 Pole

These right angle speakon compatible connectors are ideal when space is tight. These can be used for 2 pole or 4 pole cables. Increase the longevity of your cables by switching your speakon cables to right angle speakon cables.

I never "worried" about my Sewell Deadbolt banana plugs, but I switched to their spades simply because I wanted my cables to go straight down the back of the speaker stand.

I also try that plug to let cable go down, but quality was so poor.

Wago's banana plugs are the only ones I've used that have never broken

Are you sure you didn't make the connectors incorrectly?
I notice that your grub screws are sticking out way too far, even for 10 AWG cable. For two plugs, a grub screw is screwed in further. Are you sure that the other connectors are in contact?
Depending on the cable, only the conductor (preferably with a well-pressed ferrule) is clamped with the two grub screws or the conductor is clamped with the inner grub screw and the sheath of the cable with the outer one.
Are you sure they didn't push the wires in too far and just clamped the insulation?
It would be nice if you would post a picture of one of the plugs where you can also see the cable removed.

I haven't heard of any failures with this connector. Thousands of these plugs have been sold worldwide, many on Amazon. A dealer friend of mine has already assembled several hundred of these with cables and I have assembled 5 sets myself.
These plugs even have a particularly low contact resistance, which we measured as part of a project with outputs of several hundred watts.

By the way, the mandrel is only used for clamping/locking in the socket.

Poor? I think they're good.

2 out 6 I tried screwed in but not connected. And then I found inner material is plastic and lost interest.

Of course, it' my mistake that didn' read description carefully. It is described golden plated but didn't imagine that inner material is plastic. I don't want to have trouble insert can be broken inside of speaker socket and in that sense I would say this is poor quality, yes as much as I paid. Usually I prefer robust material.

 

[Flexecutioner]

I swapped out some spades for something similar and haven't had any issues. Maybe you got some junk but I don't think it's a problem with this style of connector.

 

[3125b]

I don't see the point of 4mm connectors at all for that kind of application. Just crimp on some decent lugs and use the screw connectors, it's not like you take that connection apart every couple days.

Of course personal taste is a valid option. Myself I used from tinned wire end, spades and banana plugs. The best for me which I use now are goldplated banana plugs for hi-current (used in model electropowered airplanes) and solder the wire into it. This is my final usage as far as the amplifier has the banana jacks. If not I built an short adapter wire with banana jacks (gold plated hi-current) and the appropriate connector for the amp output. For musical instruments loudspeaker speak-on from Neutrik is the best to my opinion but almost no hifi amp has such jacks.
