Cable Connector Housing with Molded Pressing Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors for connecting cables to a print circuit board are costly and complex due to the need for a pressing plate, which can damage the housing and lacks sufficient structural integrity.
Innovation Solution
A cable connector design featuring a first housing with recessed receiving spaces and holes for contacting arms and engaging arms, eliminating the need for a pressing plate by using a shell with latching arms to secure cables and terminals for direct electrical contact with the print circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing plate is used to press cables to contacts, then electrical connection is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The pressing plate is completely removed from the connector structure. Instead of using a separate pressing component, the invention integrates the cable securing function directly into the housing through molded-in-place plastic features that press the cables against the contacts during assembly
Solution Approach 2:
The housing and cable securing features are merged into a single integrated component. The housing simultaneously provides structural support, contact retention, and cable positioning functions through built-in pressing surfaces and molded features, eliminating the need for separate pressing plates
2Reliability
If a pressing plate is used to press cables downwardly, then electrical connection is achieved, but the sidewall of the housing may be destroyed
Solution Approach 1:
The pressing force is localized to specific molded-in-place features within the housing that are designed to contact and press the cables against the contacts. This localized approach concentrates the force where needed without distributing it to the housing sidewalls, preventing structural damage
3Ease of manufacture
If the housing sidewall is made thinner to reduce cost, then manufacturing cost decreases, but structural integrity is insufficient
Solution Approach 1:
The housing is pre-formed with molded-in-place pressing features and reinforced structural elements during the molding process. These built-in features provide the necessary structural support and cable positioning capability without requiring additional components or thicker walls, achieving both cost reduction and structural integrity

AI summary
A cable connector includes a first connector and a second connector. The first connector comprises a first housing defining a receiving space for receiving the second connector, and a plurality of contacts assembled to the first housing, each having a contacting arm exposed in the receiving space and an engaging arm disposed on a top surface of the first housing for being soldered with cables easily. The second connector comprises a second housing received in the receiving space of the first housing and a plurality of terminal received in the second housing for electrically contacting with the contacting arms of the contacts of the first connector.
