Electrical Connector Slide Cam Elastic Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connectors with metal shells for electromagnetic shielding require a separate spring member for elasticity, increasing component count and manufacturing costs, and impair mating functionality due to resistance against insertion force.
Innovation Solution
An electrical connector design featuring a metal shell with a slide cam made of elastic metal material, integrally formed with elastic portions that guide and press against both the mating connector and the shell, reducing the need for a separate spring member and enhancing electromagnetic shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate spring member is used to provide elasticity for electromagnetic shielding, then the electromagnetic shielding function is achieved, but the number of components increases and manufacturing cost increases
Solution Approach 1:
The patent combines the slide cam and spring member into a single integrated component. The slide cam is formed with an elastic portion that directly contacts the metal shell, eliminating the need for a separate spring member. This merging of functions reduces the number of components while maintaining the electromagnetic shielding capability through the elastic contact between the slide cam's elastic portion and the metal shell.
2Reliability
If a separate spring member is used to provide elasticity, then the electromagnetic shielding function is achieved, but the manufacturing cost increases
Solution Approach 1:
The slide cam and spring member are merged into a single integrated component, reducing the number of parts that need to be manufactured and assembled. This integration lowers manufacturing costs by eliminating separate production processes and assembly steps for the spring member, while the elastic portion of the slide cam maintains the necessary electromagnetic shielding function.
3Reliability
If a spring member is used for electromagnetic shielding, then the shielding function is achieved, but the spring force resists insertion force and impairs matability
Solution Approach 1:
The patent employs a slide cam mechanism that slides along the metal shell during insertion, with the elastic portion providing dynamic contact. The cam portion guides the mating connector along the mating direction while the elastic portion maintains contact with the metal shell. This dynamic sliding mechanism reduces resistance to insertion force compared to a static spring member, improving matability while maintaining electromagnetic shielding through the elastic contact.

AI summary
An electrical connector comprises a housing configured to be mated with a mating connector along a mating direction, a shell made of a metal material and enclosing the housing, and a slide cam made of a metal material and slidable with respect to the housing and the shell in a sliding direction perpendicular to the mating direction. The slide cam has a cam portion guiding the mating connector along the mating direction, a first elastic portion configured to be pressed against a metal region of the mating connector, and a second elastic portion integrally formed in a single piece with the cam portion and the first elastic portion and configured to be pressed against a predetermined region of the shell.
