Resin C Ring Restricts Coupling Movement in Connector Plugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connector-incorporating plugs with push-pull connections used in outdoor facilities like base stations face issues with incomplete connections due to accidental pulling during tape winding, and the use of binding bands for restricting coupling movement is cumbersome and difficult to remove.
Innovation Solution
A C ring made of resin material is detachably mounted in a groove on the barrel's outer circumference, restricting the coupling's movement towards the rear end, providing easy restriction and release, and is designed for easy handling and mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a binding band is mounted to the groove on the barrel to restrict coupling movement, then the connection state is secured, but the mounting work becomes troublesome and removal is difficult
Solution Approach 1:
The invention extracts the coupling restriction function from the binding band and integrates it into the coupling structure itself through the groove. The groove is pre-formed on the coupling to engage with a restriction member (such as a tab or latch on the barrel), allowing the coupling to self-restrain without requiring external binding bands. This eliminates the troublesome mounting and removal operations while maintaining reliable connection state.
Solution Approach 2:
The coupling structure is designed to automatically engage with the barrel's restriction mechanism through the groove. When the coupling is inserted into the barrel, the groove automatically aligns with and engages the restriction member, providing self-restraining functionality without requiring manual intervention to attach binding bands. The coupling essentially serves its own restriction need.
2Ease of operation
If the connector-incorporating plug is directed vertically upward for connection, then it can be connected to the receptacle in the base station, but the coupling may be accidentally pulled downward during tape winding causing incomplete connection
Solution Approach 1:
The groove is pre-formed on the coupling structure to engage with a restriction member on the barrel before any accidental pulling can occur. This preliminary engagement creates a mechanical interlock that prevents the coupling from being accidentally pulled downward during tape winding operations, counteracting the potential harmful force before it can cause incomplete connection.
Solution Approach 2:
The groove-restriction member engagement acts as a preventive measure that cushions against accidental pulling forces. The mechanical interlock is established beforehand, creating a protective mechanism that absorbs or prevents the harmful effect of downward forces applied during tape winding, ensuring connection completeness is maintained.

AI summary
A connector-incorporating plug which has a built-in connector in a tube-shaped barrel and in which a coupling is mounted at an outer circumference of the barrel at a front end thereof so as to be movable along a center axis of the barrel includes a C ring mounted, in a detachable manner, in a groove formed on the outer circumference of the barrel and restricting movement of the coupling toward a rear end of the barrel. The C ring is made of a resin material. An outer circumferential side portion of an intermediate portion of a C shape of the C ring protrudes back and forth in the thickness direction thereof to be thick.
