Cable Connector Assembly Dual-Surface PCB Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connector assemblies complicate the production process due to separate handling of coaxial and single wires, which increases production complexity and costs.
Innovation Solution
A cable connector assembly design where all coaxial wires are soldered on one surface of the PCB and all single wires on another, with conductive paths connecting rear pads to corresponding front pads on both surfaces, simplifying the assembly process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If coaxial wires and single wires are arranged in one row and handled separately, then the connection structure is simple, but the production process becomes complex and inefficient
Solution Approach 1:
The patent divides the PCB into two distinct surfaces: the upper surface for receiving and soldering all coaxial wires, and the lower surface for receiving and soldering all single wires. This spatial segmentation allows simultaneous handling of different wire types during production, resolving the contradiction between simple connection structure and production efficiency.
2Ease of manufacture
If coaxial wires and single wires are soldered on the same surface, then the assembly process is simplified, but wire handling and routing become complex
Solution Approach 1:
The patent transitions from a single-surface arrangement to a two-surface (three-dimensional) arrangement on the PCB. By utilizing both the upper and lower surfaces of the PCB for wire soldering, the patent simplifies wire routing and handling while maintaining ease of manufacture, as each wire type has its dedicated surface area.
3Reliability
If separate handling procedures are used for coaxial and single wires, then connection reliability is maintained, but production costs and time increase
Solution Approach 1:
The patent establishes predetermined zones on the PCB upper and lower surfaces specifically designated for coaxial and single wire soldering respectively. This preliminary arrangement of wire reception areas allows production workers to simultaneously process different wire types without interference, maintaining connection reliability while reducing production time through parallel processing.

AI summary
A cable connector assembly for mating with a mating connector in two directions includes a PCB, a cable, and a housing. The PCB includes a front end portion, a rear end portion, and a middle portion. The front end portion includes some front conductive pads, while the rear end portion includes some rear conductive pads. The PCB includes an upper surface and a lower surface. The cable includes some coaxial wires and single wires. All the coaxial wires are soldered on one surface, and all the single wires are soldered on another surface of the PCB. Part of the rear conductive pads soldered with the coaxial wires are electrically connected to the front conductive pads on the upper surface through a layer of conductive path, while the other rear conductive pads are electrically connected to the front conductive pads on the lower surface through another layer of conductive path.
