Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IC sockets require high pressing forces to secure contact pins, which can lead to pin damage and are inconvenient due to the need for additional adapters, increasing the complexity and space requirements of the mounting process.
Innovation Solution
A socket design featuring contact pins with a base portion, elastic pieces, and a lead portion, where the base portion is fitted into a through hole and the lead portion is positioned using a movable locating board, allowing for secure electrical connection with reduced mounting force and eliminating the need for additional adapters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact pins are pressed against the socket body with large pressing force to ensure holding force, then the contact pin holding force is improved, but the contact pin may be damaged and the mounting process becomes troublesome
Solution Approach 1:
The contact pin's own base portion is utilized as the locating structure. The base portion is fitted into the base portion fitting hole portion of the socket body, which automatically positions and secures the contact pin without requiring external adapters or complex pressing mechanisms. This self-service approach simplifies the mounting process while ensuring reliable holding force.
Solution Approach 2:
The locating function is extracted from a separate adapter component and integrated directly into the socket body structure. The base portion fitting hole portion is formed directly in the socket body, eliminating the need for independent adapter components and reducing mounting complexity while maintaining contact pin security.
2Reliability
If an adapter is disposed independently to support the contact pin, then the contact pin is supported, but much working process and locating space is required
Solution Approach 1:
The supporting and locating functions are merged into the socket body itself. The base portion fitting hole portion and the through hole are integrated features of the socket body, combining multiple functions (support, positioning, securing) into a single component structure, thereby reducing the total number of parts and simplifying the overall device.
Solution Approach 2:
The socket body is designed to perform multiple functions: it provides the through hole for contact pin insertion, forms the base portion fitting hole portion for positioning and securing the contact pin, and eliminates the need for separate adapter components. This multi-functional design reduces device complexity while maintaining contact pin support reliability.
3Reliability
If an adapter is disposed independently to support the contact pin, then the contact pin is supported, but much locating space is required
Solution Approach 1:
The base portion of the contact pin is nested within the base portion fitting hole portion of the socket body. This nesting arrangement allows the contact pin to be securely positioned and supported within the existing socket body structure without requiring additional external space for separate adapter components, thereby minimizing the locating space requirement.

AI summary
A socket for an electrical part, such as IC socket, to be mounted on a printed circuit board is provided with a socket body, and a plurality of contact pins are mounted to the socket body so as to electrically connect the electrical part and the printed circuit board. The contact pin includes a base portion, an elastic piece extending upward from the base portion, a lead portion extending downward from the base portion, and a contact portion formed to a tip end of the elastic piece. The lead portion is inserted into an insertion hole formed to the printed circuit board. The contact pins are inserted into the socket body of the IC socket from the lower side thereof so that the base portion of each contact pin is fitted to a base portion fitting hole portion, and the base portion is pressed by a locating board disposed to the lower side of the socket body.
