Cable Connector Hard Casing Resists Bushing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-voltage electrical equipment cable connectors made of soft materials like rubber deform easily when a cable bushing is inserted, leading to loose connections and electrical issues due to radial deformation.
Innovation Solution
A cable connector design featuring a soft body with hard casings made of materials like plastic, which provide rigidity and resist deformation, ensuring a secure connection by embedding hard casings around the connecting portions to prevent deformation during bushing insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable connector is made of soft material (rubber), then it is flexible and easy to install, but it deforms when the bushing is inserted, causing loose connections and poor electrical contact
Solution Approach 1:
The cable connector combines soft material (rubber or silicone rubber) for the main body to maintain flexibility and ease of installation, with hard material (plastic or other rigid materials) for the connecting portions to prevent deformation during bushing insertion. This composite structure resolves the contradiction by allowing the soft body to provide ease of operation while the hard connecting portions ensure reliable electrical connections without loosening.
2Ease of manufacture
If the cable connector is made of soft material, then it can be easily installed, but it cannot resist radial deformation, leading to clearance and looseness under external force
Solution Approach 1:
The connector uses a composite material structure where the soft body (rubber/silicone rubber) provides ease of installation and flexibility, while the hard connecting portions (plastic or rigid materials) provide resistance to radial deformation. This combination allows the connector to be easily installed while maintaining structural strength against deformation forces.
Solution Approach 2:
The hard material is specifically applied to the connecting portions where strength and deformation resistance are most needed, while the soft material is used for the main body where flexibility is required. This localized application of different material properties optimizes both ease of installation and resistance to radial deformation.
3Reliability
If the socket deforms during bushing insertion, then the bushing cannot be tightly connected, but using hard material throughout would reduce flexibility and ease of installation
Solution Approach 1:
The connector uses composite materials with soft body portions for ease of installation and hard connecting portions for connection tightness. The hard material is strategically placed only where structural support is needed during insertion, while the soft material maintains flexibility for easy installation.
Solution Approach 2:
Different material properties are applied to different parts of the connector: soft material for the main body to enable easy installation, and hard material for the connecting portions to ensure tight connections. This local differentiation of material quality resolves the contradiction between ease of operation and connection reliability.

AI summary
A cable connector includes a soft body. The soft body has at least one connecting portion. An outer wall surface of the connecting portion is provided with a hard casing. The soft body is made of a soft material, such as rubber and silicone rubber. The hard casing is made of a hard material, such as plastic, and has higher rigidity than the soft body. When a bushing of a cable is inserted into the connecting groove of the connecting portion, the hard casing is configured to resist deformation, so that the connecting portion will not be deformed by insertion of the bushing, thereby improving the electrical connection between the cable connector and the bushing.
