HDMI Connector Terminal Segmentation for Deformation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional HDMI connectors face challenges in reducing size while maintaining signal quality, as the length of traditional terminals can cause deformation during assembly, leading to interference and reduced signal transmission reliability.
Innovation Solution
The design features a terminal set with conductive terminals of reduced length and width, integrated terminal holders, and a unique abutting chamber with terminal slots, allowing for easier assembly and reduced size, preventing deformation and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the length of traditional terminals is reduced, then the size of the connector is reduced, but the terminals become easily deformed during assembly
Solution Approach 1:
The terminal is divided into three distinct segments: contact part, terminal arm, and solder part. Each segment has optimized dimensions - the terminal arm length is specifically controlled to provide sufficient stiffness against deformation while the contact part and solder part maintain their respective functions. This segmentation allows the terminal to achieve both compact size and deformation resistance.
Solution Approach 2:
The patent optimizes the terminal arm length parameter to a specific range that provides the right balance between being short enough for compact connectors and long enough to resist deformation during assembly. The width and thickness parameters are also adjusted to achieve the desired mechanical properties while maintaining small overall dimensions.
2Ease of manufacture
If the terminal length is reduced, then assembly with insulating body is facilitated, but signal transmission quality deteriorates
Solution Approach 1:
The terminal arm length is optimized to provide sufficient electrical connection length for reliable high-frequency signal transmission while being short enough to facilitate easy assembly with the insulating body. The dimensional parameters are carefully selected to maintain signal integrity despite the reduced overall terminal length.
3Volume of moving object
If the connector size is reduced, then it meets lighter/thinner/shorter/smaller design requirements, but adjacent terminals are too close causing interference
Solution Approach 1:
The patent arranges terminals in multiple dimensions including upper and lower rows with specific spacing relationships. The terminal arm width and positioning are optimized to maintain adequate spacing between adjacent terminals in the compact connector structure, preventing signal interference while achieving small overall dimensions.

AI summary
An electric connector includes an insulating body which includes terminal slots formed in an abutting chamber inside thereof, and the abutting part includes two arms extended from two opposite rear sides thereof in the same direction, and an accommodation space formed between the two arms; and, a terminal holder integrally formed with the conductive terminals of the terminal set is combined between the two arms, and each conductive terminal has a predetermined length, and includes a contact part inserted through the terminal slot and into the abutting chamber, a solder part disposed behind the contact part and exposed to the accommodation space, and a terminal arm with a given length formed between the contact part and the solder part. The length of the solder part is lower than the length of each arm. The solder parts can be electrically connected to an abutting side of a signal transmission part.
