NX Electrical Routing: Terminal strip

Experimenter
Experimenter

We are looking if we can use NX-Electrical-Routing for the design of our Control Panels

Does anyone have experience with using terminal strips in NX-Routing.

Terminal strip: Not a connector but terminals (for example 20pieces of the same 2level terminal 8WH1020-0AG00 who form a terminal strip 1X2, numbered from for example 1to 30 and terminal strip 1X3 15pieces of also 8WH1020-0AG00 numbered from 50 to 70)

 

How do you define the same component (terminal 8WH1020-0AG00, with connection points 1a; 2b;3a;4c) with deferent connections on a terminal strip.

How do you import an excel list (from/to/section/type wire / ..) into NX to do the automated routing

 

I’ve searched the web but didn’t found any video of routing wires to terminals (not connectors)

Hello,

We do provide some coverage for wiring to terminal blocks and strips in our documentation. See:
Home->Design (CAD)->Routing Systems->Using Routing applications->Routing Electrical->Routing Electri....

 

Content from the "Terminal usage" topic and the "Component List content for terminals" topic are included below for your reference.


---------------------------------------------------------------------------------------------------------------------
Terminal usage
A harness design may include wires that terminate with a lug that is attached directly to a device. Examples of such devices are batteries with poles (such as a car battery) and terminal blocks with screws that hold the lugs.
Lugs are of different types, but a common type is an eyelet crimped onto the wire.


Eyelet lug


Lug qualification
Qualify a lug component as a connector. A typical connector has many connections points (pins) whereas a lug only has one or two. Define a multiport in the lug component to which a path may be connected and create one or two virtual ports as needed. You can add a Fitting Port to make adding the component easier by using the Place Part tool, if desired. The lug shown below has both a multiport for the wire connection and a fitting port for component placement.

Lug placement
You can place a lug into the harness assembly using either Routing Place Part or Assemblies Add Component. If you define a fitting port for placement, Routing Place Part should be used.
Typically, you can place several lugs onto a device such as a terminal block for example. There is no mechanism available for the electrical design system to pass the information into Routing Electrical that specifies which lug attaches to which terminal of the terminal block. In the image below, three lugs are placed onto a terminal block.


Three lugs on a terminal block
Each lug has a unique identifier defined in the component list. Through Electrical Component Navigator, you must assign these designators in order to route the wires. The problem is to determine which identifier to assign to which lug. Since the ports of a device are not uniquely identified, the system cannot automatically make these assignments.
There are different ways to resolve this problem. One solution is to have comments provided within the component list that indicate the position of each designator. (This lug goes to terminal block 2 slot 3.) Another solution is to have an attribute or name assigned to each port of the terminal block (SLOT = "J72A") that can be reconciled with the Unique ID from the component list by the designer. You can devise other such methods according to a defined process.

 


Component List content for terminals
Include the lug in the component list as a connector. Assign the Unique Identifier the same way other connectors are assigned.
Connection List (.plmxml) content
No special consideration is required for a wire that terminates at a lug. Either the from connector or the to connector is the lug, as identified in the Electrical Component Navigator.
Path creation
Create a path leading to the multiport of the lug as you would any typical connector.
Routing the wire leading to a lug
A wire that leads to a lug routes the same way other wires are routed.
Formboard
A lug carries to the formboard model as a connector.
