Electric Socket Locking Jack Connector Pull-Out
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sockets with XLR plugs have reliable locking mechanisms, but jack connectors are only snapped in place by a spring-elastic element, allowing them to be partially or fully pulled out when the cable is pulled, disrupting electrical contacts.
Innovation Solution
The socket incorporates a locking device for the jack connector with a locking extension that engages in the contact tip's constriction and a blocking part that holds it in place, using the same actuation unit that locks the XLR plug, allowing the blocking part to disengage and enable the locking extension to be pushed out, ensuring the jack connector remains secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-elastic element is used to snap the jack connector into place, then the jack connector can be easily inserted, but the jack connector can be partially or entirely pulled out when the cable is pulled
Solution Approach 1:
The locking mechanism is divided into two functional parts: a locking extension that engages with the contact tip constriction to prevent pull-out, and a blocking part that prevents the locking extension from being pushed out. This segmentation allows the socket to provide both easy insertion and secure retention for jack connectors
Solution Approach 2:
The same actuation unit is used for both XLR plug locking and jack connector locking operations. When the actuation unit is actuated, it simultaneously disengages the locking protrusion from the XLR plug locking recession and disengages the blocking part to allow locking extension release, enabling unified control of both connector types
2Reliability
If a locking mechanism is added for the jack connector, then connection stability is improved, but device complexity increases
Solution Approach 1:
The actuation unit serves multiple functions: it locks and unlocks XLR plugs by acting on the locking arm, and it locks and unlocks jack connectors by acting on the blocking part. This multi-functionality reduces the need for separate control mechanisms for different connector types, thereby limiting the increase in device complexity while maintaining improved reliability

AI summary
Socket for alternatively creating an electrical plug-in connection having a first plug (1), especially in the form of an XLR plug, or having a second plug constructed in the form of a jack connector (7), whereby the socket comprises a locking arm (22) with a locking protrusion (23) that engages, in the plugged-in state of the first plug (1), into a locking recession (6) in the plug housing (5) of the first plug (1), and an actuation unit (24), that in an active position keeps the locking protrusion (23) disengaged from the locking recession (6) of the first plug (1). The socket also has a locking device for the jack connector (7) that comprises a locking extension (37) that in the plugged-in state of the jack connector (7) engages in a constriction (12) of the contact tip (10) of the jack connector (7), and a blocking part (38) that has a contact surface (39) that in a blocking position of the blocking part (38) rests against an opposite contact surface (40) of the socket. By means of the actuation unit (24), a section of the blocking part (38) adjoining the contact surface (39) can be displaced in the plug-in direction (14) and the contact surface (39) of the blocking part (38) can be made to disengage from the opposite contact surface.
