Coaxial Connector Mold Layout for Tighter Board Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial connectors have a large outer size due to double resin molding, which restricts the spacing between connectors and hinders effective use of board area when multiple connectors are arranged side by side.
Innovation Solution
A coaxial connector design where only the primary molded part defines the outer dimensions, with a secondary molded part at the lead-out portion, reducing the overall size and resin usage, and incorporating a magnetic powder mixed resin for noise resistance and bendability.

Engineering Contradiction Analysis
1Reliability
If double resin molding is applied to protect connection and holding portions, then waterproof property and protection are improved, but connector outer size increases
Solution Approach 1:
The connector is divided into two distinct molded portions: a first molded part covering the connection portion and a second molded part covering the holding portion. This segmentation allows each portion to be optimized independently - the first molded part provides waterproof sealing at the connection interface, while the second molded part provides protective coverage at the holding portion, eliminating the need for overlapping double molding and reducing overall connector size.
2Area of stationary object
If connector portion size is reduced, then board area utilization is improved, but protection and waterproof property may be compromised
Solution Approach 1:
By segmenting the molded structure into separate first and second molded parts positioned at different locations (connection portion and holding portion respectively), each part can provide adequate protection for its specific function without requiring increased overall connector dimensions, thus maintaining board area utilization while ensuring protection.
Solution Approach 2:
Different molded parts are provided at different locations with different functions - the first molded part at the connection portion provides waterproof sealing properties, while the second molded part at the holding portion provides mechanical protection. This local differentiation ensures that protection is provided exactly where needed without adding unnecessary size elsewhere.

AI summary
A connector includes a cable including at least one core wire and a shielding wire arranged around the core wire with an insulating member interposed therebetween, a plug part connected to the cable and capable of fitting with a receptacle, a primary molded part including a connection portion between the core wire and a conductive member of the plug part, and a secondary molded part arranged at a lead-out portion of the cable. The dimension of the primary molded part is an outer diameter or a thickness of the plug part.
