Harness-Side Connector Movable Housing for Compact Image Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional small-sized image pickup apparatuses face challenges in reducing size due to the need for large substrate-side connectors that absorb positional displacement, leading to increased size and complexity.
Innovation Solution
The use of a flexible linear conductor that supports a movable housing within the image pickup apparatus, allowing for three-dimensional displacement to absorb positional displacement without the need for complex terminal structures, thereby simplifying the connector design and reducing overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a substrate-side connector with elastic deformation terminals is used to absorb positional displacement, then the fitting position displacement is absorbed, but the connector size becomes large
Solution Approach 1:
Instead of making the substrate-side connector movable to absorb displacement, the invention makes the harness-side connector movable. The movable housing in the harness-side connector can displace relative to the fixed substrate-side connector, achieving the same displacement absorption function while keeping the substrate-side connector compact and fixed in structure.
Solution Approach 2:
The invention employs a flexible cable connecting the movable housing to the external harness. This flexible cable allows the movable housing to displace in multiple directions while maintaining electrical connection, enabling compact connector design without requiring large elastic deformation terminals in the substrate-side connector.
2Reliability
If terminals with outwardly bent shapes are used to achieve displacement absorption, then the fitting position displacement is absorbed, but the substrate connection protrudes outside the housing
Solution Approach 1:
The invention reverses which connector contains the movable structure. Instead of having the substrate-side connector with protruding bent terminals, the movable structure is placed in the harness-side connector. This allows the substrate connection to remain fixed and non-protruding while the harness-side connector absorbs displacement through its movable housing.
3Reliability
If a large projected area substrate-side connector is used, then the displacement absorption function is achieved, but the image pickup apparatus size increases
Solution Approach 1:
By moving the displacement absorption function from the substrate-side connector to the harness-side connector, the substrate-side connector can be designed with a compact projected area. The movable housing in the harness-side connector handles the displacement absorption, allowing the overall image pickup apparatus to be smaller while maintaining the same reliability function.

AI summary
To reduce a size of an image pickup apparatus including a connector that has a terminal having a positional displacement absorption function. A harness-side connector of an image pickup apparatus includes a movable housing that holds a harness-side terminal, a movable gap in which the movable housing can be displaced, and an accommodation portion that accommodates the movable housing in a displaceable manner, the movable housing being displaceable owing to flexibility of a core wire.
