Review on 📦 Efficient Distribution of Position Terminals with Electronics Salon Module by Jeremy Meza

Looks like a neat product with very interesting possibilities for modifications, but I haven't burned it yet! The numbers on the device are nice and clear. Well readable. The black on yellow is formed from a single strip of material and appears to be well bonded. The white on dark green is actually printed onto the green circuit board underneath. I photographed a 30 amp unit but it is essentially the same design as the 24 amp unit. 24A 30 pin version. Each is 6-3/8 inches long. I plan on putting them both on the same 12" DIN rail and having 30 24 amp connectors and 15 (maybe 16) 30 amp connectors after trimming the 30 amp connector down a bit. I've attached some photos so you can see other aspects of the design. Both versions have the same structure. I wanted the 30 amp version for just a few power outlets, but I don't have room for all 20 outlets, so I wanted to see if I could cut it out. It looks easy. The end cap is removed with two screws. The body is made of extruded plastic but seems sturdy enough. Therefore, it can be easily cut. The electrical connections are simply soldered to the circuit. a board that has a thick layer of solder connecting adjacent connectors, and then the board is inserted into slots in an extruded housing. This makes the device hollow with some space under the PCB, yet electrically isolated from the aluminum DIN. I realize that neither solder nor copper, say f the circuit board under solder, actually handles up to 30 amps, but the metal terminals seem pretty good. (See photos) For cases where the current is higher I can solder additional copper rails to the connectors or even just add a thicker layer of solder. I assume the metal rods from the screw connectors conduct electricity over this short distance, but there really isn't any other way to dissipate heat other than through the wires themselves. One of the advantages of this design is that other connections or even simple circuits can actually be installed inside the housing. In my case for low current connections I need some diodes connecting different positions so I can just solder them inside and don't have to add a small PCB outside! Also, some circuits require the terminal to be tied together as a common connection, so I could do this internally rather than trying to put 3 or 4 wires in a screw terminal hole. The biggest problem with this is that the schemas are hidden, so documentation is important! Maybe draw a diagram on the front of the device? On the other hand, there is a small visible gap between the screws along the entire length of the device. If he drills a small hole right between two screws, he hits a solder joint on the circuit board. Short circuits, diodes, etc. could be soldered to these points in a way that is visible, electrically isolated and at the same time mechanically protected by a plastic screw housing! You can see this space in the photo showing the screw heads. The electrical terminals themselves are two pieces with serrated surfaces, pieces of metal, the top of which is fixed and fits into the circuit board, while the other is pulled out by a screw mechanism for clamping. against the top. (It's not just a screw pushing a wire into a curved surface like some of the cheaper devices are made for.) So they have to be much stronger and can actually hold more than one wire, even a solid one. the cable. You can certainly hold a spike, but since most spikes have insulating tabs, you can't put more than one spike in a hole. There is a sharp plastic edge at the top of the hole that protrudes below the surface of the metal clip. I assume this is to bite into the wire's insulation to protect the wire from being pulled. However, with larger cables it may be necessary to tighten the clamp screw to ensure proper cable connection. Another interesting thing is that the extruded case has a couple of grooves just below the PCB (seen in the end photo) that are just the right width to hold another PCB. In fact, the circuit board with screw connectors fits exactly to this width. This groove is used by the small protrusions of the end plates to mechanically grip the pressed body. However, these projections only protrude a distance towards the shore, leaving most of the groove unused. The name "DINKLE" is cast on the end plate. All in all it looks like a pretty useful screw connector. One caveat might be that the extruded plastic case might soften when it gets hot?! However, apart from the DIN terminal, everything important is built into the circuit board.
