Wire-arranging pin for transformer winding frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transformers face issues with insufficient contact area between the outlet parts of the secondary winding coil and pins, leading to poor soldering and heat dissipation, which reduces efficiency due to scattered single-core wires and elevated operating temperatures.
Innovation Solution
The introduction of wire-arranging pins with a first connecting part, a main fixing part featuring a notch, and a second connecting part, which securely hold the outlet parts of the winding coil, enhancing the contact area and facilitating better soldering and heat dissipation by allowing the pins to be inserted into circuit board holes without hindrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the outlet part of the secondary winding coil is soldered on a specified soldering site of a pin, then the transformer can be assembled, but the contact area between the outlet part and the pin is insufficient
Solution Approach 1:
The pin structure is extended in the vertical dimension by adding a protruding portion that protrudes from the surface of the winding frame. This dimensional extension creates an enlarged contact area between the pin and the outlet part of the secondary winding coil, allowing for better soldering without increasing the horizontal footprint of the component.
2Ease of operation
If the secondary winding coil is formed of a plurality of single-core wires, then the coil can be flexible, but the wires are readily scattered at the outlet part and difficult to arrange
Solution Approach 1:
The pin is provided with a protruding portion that protrudes from the surface of the winding frame. This protruding portion acts as a preliminary positioning structure that guides and collects the scattered single-core wires at the outlet part of the secondary winding coil, making wire arrangement easier before soldering occurs.
3Ease of manufacture
If the soldering site is higher than a tip portion of the adjacent partition plate, then the soldering can be performed, but the soldering site becomes a hindrance from inserting the pin into the circuit board
Solution Approach 1:
The pin structure is segmented into two functional parts: a mounting portion that inserts into the circuit board and a protruding portion that provides the soldering site. The protruding portion is positioned to extend from the surface of the winding frame, separating the insertion function from the soldering function in space, thus eliminating the interference between these two operations.
4Device complexity
If the contact area between the outlet part and the pin is insufficient, then the assembly is simple, but the heat generated from the transformer is not easily dissipated away
Solution Approach 1:
The pin structure utilizes the vertical dimension by adding a protruding portion that extends from the surface of the winding frame. This dimensional addition enlarges the contact area between the pin and the outlet part of the secondary winding coil, improving heat dissipation capability without significantly increasing the overall complexity of the pin structure.

AI summary
A wire-arranging pin is mounted on a winding frame for facilitating fixing an outlet part of a winding coil. The winding coil is wound around the winding frame. The wire-arranging pin includes a first connecting part, a main fixing part and a second connecting part. The first connecting part has a first end and a second end, wherein the first end is coupled to the winding frame. The main fixing part is coupled to the second end of the first connecting part and has a first notch. The outlet part of the winding coil penetrates through the first notch to be held by the main fixing part. The second connecting part has a first end coupled to the main fixing part.
