Solution Overview

Problem

Existing sockets for coaxial cables in telecommunications networks face connection issues due to poor soldering quality and solder joint cracks, which can lead to unreliable connections.

Innovation Solution

A socket design that eliminates soldering by using a chassis with connection terminal elements, a cover, and an electronic circuit where first connecting elements on the circuit board form galvanic connections with second connecting elements through pressure when the cover is placed on the chassis, allowing for secure connections without soldering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soldering is used to connect first connecting elements to second connecting elements, then electrical connections can be established, but connection problems occur due to poor soldering quality or cracks in solder joints

Engineering Contradiction:
Improveconnection reliabilityVSAvoidsoldering quality control
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts and eliminates the soldering process from the connection method. Instead of using solder to join the connecting elements, the patent uses direct mechanical and electrical contact through spring-loaded contact elements that press against the circuit board contacts, thereby removing the source of soldering-related connection problems

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the thermal-chemical soldering process with a mechanical contact system. Spring-loaded contact elements provide both mechanical support and electrical connection through direct contact and elastic pressure, substituting the soldering mechanism with a purely mechanical connection system that avoids all soldering quality issues

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If soldering is used to connect connecting elements, then electrical connections are established, but the manufacturing process becomes complex and time-consuming

Engineering Contradiction:
Improveconnection stabilityVSAvoidmanufacturing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The soldering step is completely extracted from the manufacturing process. The connecting elements are designed to be inserted and secured mechanically without any soldering operation, significantly simplifying the manufacturing process and increasing production speed while maintaining connection stability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spring-loaded contact elements perform multiple functions automatically: they provide mechanical support, ensure electrical contact, and compensate for manufacturing tolerances through their elastic deformation. This self-adjusting mechanism eliminates the need for precise soldering and complex assembly procedures

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a socket for telecommunications networks, in particular community antenna systems, comprising at least one chassis (1) with at least one connection element (7), an electronic circuit with at least one first connection element, and with at least one second connection element (21), wherein the first and the second connection elements are galvanically connected to each other. According to the invention, the galvanic connection has at least one conductive lamella (4) that exerts pressure on the first connection element. Soldering the first connection elements to the second connection elements is therefore unnecessary.
