Connector Locking Knob and Bolt Design for Tool-Free Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for communication devices face issues with reliability, usability, and water resistance, particularly due to the inconvenience of using external tools to secure the locking bolt and poor signal transmission quality.
Innovation Solution
A connector design featuring a locking knob and bolt with a beveled edge for synchronous rotation, an elastic waterproofing rib, snap-fitting structure, anti-slip strips, and integral inner mold and PCB board with pins, allowing for easy connection and disconnection without external tools, while providing IP67-rated water resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking bolt with a small knob is used to secure the accessory side, then the connector provides good reliability and water resistance, but it is inconvenient for users to fasten and loosen the locking bolt without external means
Solution Approach 1:
The locking mechanism is divided into two functional parts: a locking bolt for securing the connection and a separate locking knob for operation. The locking bolt engages with the host to provide reliable locking, while the locking knob extends outward to provide a convenient gripping surface for users to fasten and loosen the connector without needing external tools.
2Object-affected harmful factors
If a pin-based connector with a locking bolt is used, then the connector provides good water resistance, but the structure becomes complex and difficult to operate
Solution Approach 1:
The locking bolt and locking knob are combined into a single integrated component. The locking knob is directly formed on the locking bolt, merging the securing function (bolt) and the operating function (knob) into one unified structure. This reduces the number of separate parts while maintaining both the water resistance provided by the locking mechanism and the ease of operation provided by the extended knob.
3Volume of moving object
If a conventional connector with limited space is used, then the connector structure is compact, but the locking bolt knob becomes small and difficult to operate
Solution Approach 1:
The locking knob extends in a direction perpendicular to the main body of the connector, utilizing the vertical dimension rather than increasing the horizontal footprint. This allows the knob to have sufficient length for easy gripping and operation while keeping the overall connector profile compact and suitable for limited installation spaces.

AI summary
A connector comprises a connector body (40), a connector upper housing (10), a locking component (20) and a connecting assembly (30) provided within the connector body (40). The locking component (20) includes a locking knob (23) and a locking bolt (21). Holes are provided on the middle of the connecting assembly (30) and the connector body (40) respectively to match with the locking bolt (21). The diameter of the locking knob (23) of the locking component (20) is larger than the width of the connector body (40). The connector upper housing (10) is fixed on the connector body (40) and restricts the locking knob (23) between the connector body (40) and the connector upper housing (10).
