Connector Terminal Press-Supporting Members Disperse Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with deformation under high contact pressure, particularly when the housing is subjected to high temperatures or high currents, leading to unstable connections due to the deformation of the terminal and housing components.
Innovation Solution
The connector design incorporates first and second press-supporting members that extend from the fixing base along the sides of the connection object, dispersing the pressing force and preventing deformation by not being fixed to the housing, thus maintaining stability under increased contact pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact pressure to be applied from the first contact member and the second contact member to the connection object is set to a high level so as to stabilize the contact between the terminal and the connection object, then the contact stability is improved, but the joining member joining the first contact member and the second contact member may deform away from each other, leading to unstable contact
Solution Approach 1:
The pressing force support function is segmented between multiple components: the first press-supporting member, second press-supporting member, first contact-receiving part, and second contact-receiving part. This segmentation distributes the mechanical stress and prevents concentration on a single joining member, resolving the contradiction between maintaining high contact pressure and preventing joining member deformation.
2Reliability
If the contact pressure generated as a pressing force by the first contact member and the second contact member is applied to the housing for a long time, then the contact pressure is maintained, but the housing may deform under the pressing force, particularly if the housing is heated in an environment at a high temperature or with the supply of a high current
Solution Approach 1:
The pressing force transmission path is extracted from the housing by introducing dedicated press-supporting members. The first and second press-supporting members are configured to support the pressing force without transmitting it to the housing, effectively separating the contact pressure maintenance function from the housing structure and preventing housing deformation under thermal or electrical stress.
3Stability of the object's composition
If the first press-supporting member and the second press-supporting member are configured to disperse the pressing force, then the deformation of contact members and housing is prevented, but the device complexity increases
Solution Approach 1:
The press-supporting members are merged with the contact-receiving parts to form integrated components. The first press-supporting member includes both the first joining member and the first contact-receiving part, while the second press-supporting member includes the second joining member and the second contact-receiving part. This merging reduces the number of separate components and simplifies the overall structure while maintaining the force dispersal function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures that the terminal and connection object remain stably conductively connected while preventing deformation of the terminal and housing, even under high contact pressure, and reduces the size of the connector without increasing its size significantly.
Implementation Method 1
The second contact member serves as a cantilever spring member. When the connection object is inserted into the connector, the second contact member presses the connection object against the first contact member.
Implementation Method 2
The first press-supporting member and the second press-supporting member are each in a form of a cantilever extending from the fixing base without being fixed to the housing at all.

AI summary
To provide a connector that is less deformable even under a high contact pressure. A connector includes a housing having a fitting chamber, and a terminal that comes into conductive contact with a pin terminal in the fitting chamber. The terminal includes a fixing base fixed to the housing, a contact member extending from the fixing base and pressed against the pin terminal, and right and left press-supporting members extending from the fixing base. The press-supporting members include respective contact-receiving parts that face the contact member in the fitting chamber and are positioned side by side in a direction intersecting a direction of insertion of the pin terminal into the fitting chamber. Since the pressed pin terminal is received by the plurality of contact-receiving parts, the pressing force can be dispersed therebetween. Hence, the deformation of the contact member and the contact-receiving parts can be prevented.
