Bottom of a heat shrink using a bezier curve drawingĪs you can see, I used the Bezier Curve to create the top and bottom, Now the reasoning behind this is because this will be placed on the mechanical drawing (as a heat shrink has no electrical purpose or functionality). Top of a heatshrink using a bezier curve drawingįigure 7. Seen below are the top and bottom part of the heat shrink:įigure 6. The way to create this drawing is using the Bezier curve and have two embedded in one component. HeatshrinksĪs stated before, heat shrinks are used to bundle wires together at the end of the cables. Let’s see how they are treated in the schematic drawing. But much of this will be explained later on. Now how these are assembled can be explained in a set of assembly notes. How a crimp is placed on a schematic diagramĪs stated previously, the connector head is connected on one side while the other side continues the wire up to the cable. The reason behind this is because when it comes time to draw the schematic, we will wire up to the box side edge of the symbol, and the zero-length pin will form the netlist connection.īelow shows a representation of how one can place a socket/pin inside a schematic drawing:įigure 5. Notice for socket and pin that there is a small black dot on the left hand side, this is actually the Altium Designer ® schematic pin object, only with the length set to zero. The indentation represents a pin that is going to insert into the socket. In this schematic symbol, it is represented in the same rectangular shape, however, we have indented the shape to designate it as a socket. The socket has a much different graphical representation as seen in Figure 4 : But we will discuss more on that in a later blog. By using parameters for this we can do a direct comparison in tabular reports or even use a custom script as a cable Design Rule Check to compare wire and crimp gauges etc. Having these two parameters (at minimum) allows us to easily check that the cables, crimps, and connector heads are all fully compatible. The benefit of this is to ensure the connectivity of the design is accurate before proceeding with the assembly process.

It is within these Component Properties where you will create parameters that designate the true properties of the pin and how it can be compared against a connector head or cable component through a B.o.M (Bill of Materials) or other report. Component Properties with the Parameters Contact Plating and Wire Gauge That is why the pin on the left hand side is pointing in an outward direction.Īfter creating the graphical attributes, within the properties of the component, you will notice two critical parameters that are referenced in there and they are the “Contact Plating” and the “Wire Gauge” (refer to figure 2 ).įigure 2. This represents a pin as pins are mechanical objects that stick out of a connector head. For the main symbol (like that of figure 1 ), I prefer the geometric shape takes on a rectangular form with the exception that the right hand side designates an outward formation. Below in figure 1 is the schematic symbol for a crimp Pin:įor clarity, you could create a second sub-part which includes a JPEG or bitmap image of the crimp. Instead, the component only contains the schematic symbol(s) themselves. These components are slightly different from their other counterparts in that they do not necessarily need a 1:1 drawing (like the connector head). For the most part, we need these for the Bill of Materials, but there are a few other advantages. The other component is the heat shrink to properly bundle the wires between the cable and connector head. The first is the crimp (pin/socket) that will be embedded in the connector head if the assembly calls for it. There are two additional schematic symbols that can be added into your.
