On the left is a crimp pin to fit inside a polarized housing. Below is an image of a few crimped pins before being inserted in their plastic housing. They are used for connecting to PCBs designed with 0.1' PTH pads. One example can be found in the pre-terminated, premium jumper wires. The crimp pin may also have a locking tab and terminal stop when the pin is inserted in a plastic housing.Ĭrimp Pin Cut from Reel for Polarized Connector The additional crimp tabs for insulation provide strain relief. wings) to crimp over wire and its insulation. Instead of a barrel crimping down on a wire, the connector may include two crimp tabs (i.e. Depending on the design, the connector can be designed in a way to fit into a plastic housing. Remember, there are hundreds of types of electrical connectors out in the world. In this case, the crimped wires were used to connect multiple devices to ground. The image below demonstrates two wires crimped with female spade headers for the middle connections. You'll need to ensure that the combined wire diameter is able to fit in the crimp connection and the crimp connector is able to handle the amperage of the project. Tip: Depending on the application, two wires can be crimped with together in a single crimp connector.

If the stripped wire fits up into the metal portion of the barrel with little or no free space, the connector is the right size. The amount of exposed wire should be equal to the length of the metal barrel on the connector, usually around ¼” or so. We'll assume that you are using stranded wire so that th wire conforms to the crimped connection. If you must use solid core wire, it is a good idea to solder the wire in place after you crimp it.įirst, the correct size wire must be chosen for the terminal size, or vice versa. There is also a greater chance for a crimp connection to come loose with solid core wire because the wire will not conform to the terminal as well. Many believe crimping to solid core wire creates a weak point in the wire, which can lead to breakage.

There are several arguments for and against using solid core wire with crimp connections. Air pockets allow moisture to collect, moisture causes corrosion, corrosion causes resistance, resistance causes heat, and may ultimately lead to breakage. Why is this level of perfection required? A poor crimp leaves air pockets between the wire and connector. Using the wrong tool will not achieve a good crimp! If you were to cut a well executed crimp in half you would see a solid form of wire and connector.

A good crimper when used correctly will make a cold weld between the wire and the barrel of the connector. Warning! Pliers are not crimpers! Neither are hammers, vises, needle nose pliers or flat rocks. Depending on the design and application, these connectors can come in different flavors like flanged fork or locking ring terminal. double crimp) that is shown on the bottom right. These can slide into the female spade connector (a.k.a. On the far, upper right we have a male spade connector (a.k.a. While the ring terminal provides a more reliable connection, you would need to completely remove the screw before installing the terminal. The ring terminals in the middle are also useful for connecting wire to screw terminals. Screws can be partially screwed in before installing the terminal. spade, or split ring) is useful for connecting wire to screw terminals by sliding the fork into a screw terminal's socket. To the right, the forked connector (a.k.a. On the far, upper left, we have an insulated splice connector to connect two wire ends together. Connectors may join two lengths of wire together or connect a wire to an electrical terminal.īelow area few connector types. There are hundreds of types of electrical connectors. The connection may be temporary or serve as a permanent electrical joint between two wires. An electrical connector is a device for joining electrical circuits together using a mechanical assembly.
