I want to connect a Raspberry Pi to an 8-relay board, such as this one. enter image description here

Together with ground and power this amounts to ten wires. One option to connect the two is by using female to female jumper cables, such as these.

However, this will result in a messy and delicate connection. For example, if one of the wires is accidentally pulled, there's the risk of reinserting it to a wrong pin. What's the professional way to connect the two boards with a cable?

The black housings are available for more than just one contact, as one row or two row version. The contacts are crimped to the wires , which means you either have a crimp tool or somehow solder it. Ideally, you can use your cable, remove contacts from the housing, and just push them into the bigger housing.

Edit (by Milliways) To add to the answer I have a selection of housings I purchased on eBay. I use these with a crimping tool (their original purpose) or on existing jumper cables. enter image description here
