Solution Overview

Problem

Existing electrical sockets for data transmission cables are cumbersome to handle and require multiple parts, making them time-consuming to connect and costly to manufacture, while also lacking a universal strain relief function for different cable diameters.

Innovation Solution

An electrical socket design where a single strain relief part moves from a release position to a strain relief position, simultaneously positioning and securing the wire receiving part, absorbing external forces, and establishing electrical connections, using a combination of guide elements and locking surfaces to facilitate easy handling and reduce component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate parts are used for strain relief and wire positioning, then the strain relief function is reliable, but the device complexity and number of components increase

Engineering Contradiction:
Improvestrain relief functionVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the strain relief part with the wire receiving part into a single integrated component. The strain relief part includes a wire receiving part that can be inserted into the cable receptacle together with the data transmission cable, and this integrated part performs both wire positioning and strain relief functions simultaneously, eliminating the need for separate components while maintaining reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The strain relief part is designed to perform multiple functions: it receives and positions the wires, provides strain relief for the cable, and can be locked in different positions (release and strain relief positions). This multi-functional design reduces the overall component count while ensuring reliable strain relief and proper wire positioning

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If multiple separate parts are used for wire positioning and strain relief, then the positioning accuracy is improved, but the ease of manufacture decreases

Engineering Contradiction:
Improvewire positioning accuracyVSAvoidproduction cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

By integrating the wire receiving part and strain relief part into a single component, the patent simplifies the manufacturing process. The integrated design allows for fewer assembly steps and reduced production complexity while maintaining the precision required for proper wire positioning through guide elements and locking surfaces built into the single component

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If a fixed strain relief mechanism is used, then the strain relief function is simple, but the adaptability to different cable diameters is reduced

Engineering Contradiction:
Improvemechanism simplicityVSAvoidcable diameter compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The strain relief part is designed to be movable between a release position and a strain relief position. This dynamic design allows the mechanism to adapt to different cable diameters by adjusting its position, while maintaining structural simplicity. The movable nature enables the same mechanism to accommodate various cable sizes without requiring multiple fixed configurations

Inventive Principle:
Principle #15Dynamics

4Reliability

If separate strain relief and wire receiving parts are used, then the strain relief function is reliable, but the handling time increases

Engineering Contradiction:
Improvestrain relief functionVSAvoidconnection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The integration of wire receiving and strain relief functions into a single part allows both functions to be performed simultaneously in one insertion motion. The wire receiving part can be inserted into the cable receptacle together with the data transmission cable, eliminating the need for separate positioning and strain relief steps, thus reducing connection time while maintaining reliable strain relief

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to an electrical socket (10) with a housing (14) having a plug receptacle (28) and a cable receptacle (36), wherein contact springs (30) are arranged in the plug receptacle (28) which can be contacted by associated plug contacts of a connector and each can be electrically connected to a wire connection element (32), and with a wire receiving part (38) which can be inserted into the cable receptacle (36) together with a data transmission cable (12) and positioned on the wire connection elements (32) for receiving the wires of the data transmission cable (12), and with at least one strain relief part (78, 80) which can be moved back and forth between a release position and a strain relief position.To simplify the handling of the socket (10) and to reduce the number of individual parts required, at least one strain relief element (78, 80) can be inserted into the cable receptacle (36), wherein in the release position it releases the cable receptacle (36) and in the strain relief position it immerses itself in the cable receptacle (36) and, during the transition from the release position to the strain relief position, moves the wire receptacle element (38) from a pre-assembly position to a final assembly position and secures it in the final assembly position, wherein it can be secured to the housing (14) in the release position and in the strain relief position via a releasable locking connection, which has several locking stages in the strain relief position.
