Low Voltage Wire Connector No Wire-Stripping Required H&T Type 2 Pin Black Wire Splice Connectors for Lighting Toy Audio Vehicle Audio Automotive Video Uses (Black H2 15pcs + T2 15pcs)

Used two of these to install a device on my motorcycle (under the seat). They are easy to use and appear to hold the wires in place securely. Thus far after a month they are still secure and works well. I should point out that they are not waterproof but then I never expected them to be.

I'm liking these connectors. These are made of durable plastic and metal. I tested these and was able to open and reuse these four times without an issue. The plastic is strong enough to be forced open multiple times and not break. They are very easy to use and offer a secure connection between wires and once closed they stay locked unless you pry them open. I did not give 5 stars because these are in no way water resistant and offer no real protection against a catastrophic short if they get exposed to water. Unlike similar connectors that are filled with a non-conductive gel, these have little to no protection against the positive and negative of the power source coming into contact with water. Wholeheartedly can recommend these for dry locations but not for those exposed to the elements.

I used these connectors for connecting microcontrollers to battery. Very nice overall. My only concern is if you accidentally close the clip, it's rather hard to reopen it again. Also obviously since you don't solder anything here - it's all solderless clip-on, the connection joint point is rather big, about 1 inch long. So if you need to plan how you'd hide the wire with this plastic thing on it. In my case the plastic thingy in between the wires didn't quite mater much, as I was not after making it look pretty at all. Good product, good idea.

I purchased these to do work on a low-voltage electrical system in my golf cart. The existing lines for various lights run the length of the vehicle, and adding additional side reflectors was looking like a bit of a nightmare until I saw these. This pack has two sets of connectors, one for splicing pairs of wires together, and another for tapping into an existing wire to fork off another pair. I used mainly the latter, but did use one of the pair splicers to move/extend the line for one of the upper rail lights.The connectors work rather well with 20 gauge wire. One set I had was 16 gauge, which worked only if I stripped the insulation first (but that's not their fault, it's rated for 18 to 22). For proper gauges, simply place the wire in the clamp system and press down until the wires are gripped in the tongs. They automatically slice through the shielding and connect with the wire inside. When using the tap style connectors, pay attention to which line goes to which, or you may wind up inverting your polarities! The path is easy to see thanks to the clear plastic. The grips can be pulled open again with a small screw driver if needed, but will leave the wires with a split in the insulation if you do. You'll probably never want or need to do so, but it's nice to know the option is there.The only thing of note is that if you're not using 18 gauge wire (and maybe even if you are) these make no attempt at waterproofing the connection. If you're using these in an exposed system, or in an area with mild exposure (like under a golf cart), you probably want to have something to help with that, like hot glue, epoxy, or shrink wrap. Given the solid connection and ease of use, these definitely make simple fixes and add-ons easier.

Pretty simple device. I especially like the T type as it helped me clean up some wiring on a control panel with several buttons mounted to a hinged front panel. You don't have to strip or cut the wires and I had good success with all my wires making a good connection. This is not for high current applications or larger wires. 18 gauge would be the largest wire I would use with this item but 20-24 is even better.

Whenever I need a custom made cable, I'm more than happy to strip wires, solder a few joints, and heat shrink them back together. That being said, it's a good amount of effort, especially if the cables aren't easily removable and have to be worked on on-the-spot (thinking: in a car, etc).These connectors are great. If you have two wires you need to splice together, just throw them both in and shut the hatch. If you need to splice a third wire inline (i.e. split 1 cable to 2 cables), then use the H style and you're good to go. No insulation trimming, no nothing. They're rated for 18-22AWG, but I was even able to get good connections at 26AWG. At 28AWG, I couldn't get a secure connection, but that is expectable. Once the connectors are sealed, they hold the cable tight and there's no worry about slipping / connections coming loose.I tested the resistance on my bench equipment to ensure that these connectors are making good electrical contact with the cables. The lower the resistance, the higher capacity for high-voltage connections these cables have. On my calibrated equipment, I only saw an increase in resistance by 0.002 Ohms when connected to 26AWG stranded cable, ensuring very good and dependable electrical connections. I didn't test the mechanical ruggedness of the connector, but only time will tell. Ideally, I wouldn't put these connectors in any physically strenuous situation in any case.One thing I didn't test was the electrical isolation of the two parallel connectors. Especially in the H style cable, the internal metal connections do intersect with each other and might cause a problem with leakage for high speed connections. Another thing I didn't test was reuse of the connector - these things close pretty tight and are not easy to re-open, ensuring good clamp force on the cable. However, if you do re-use them, I'm not sure what their life expectancy would be as you stress the plastic hinge.
