1Speed

If a traditional connector structure with female head, middle plate, and backplane connectors is used, then the connector can achieve high-speed data transmission, but the structure becomes complex and production cost increases

Engineering Contradiction:
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent combines the female head, middle plate, and backplane connectors into a single integrated stack type female connector. The terminal assembly integrates multiple terminal members (40-pin, 15-pin, 7-pin, 6-pin) that were previously separate components, eliminating the need for multiple separate connector parts while maintaining high-speed data transmission capability through the unified structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stack type female connector is designed with multi-functional terminal members that can connect with both SAS and PSAS male connectors. The terminal assembly incorporates different pin configurations (40-pin for PCIe, 15-pin+7-pin for SAS, 6-pin for power) within a single connector body, allowing it to serve multiple connection purposes simultaneously.

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

2Adaptability or versatility

If a traditional connector structure is used, then the connector can provide multiple connection interfaces, but the production cost increases

Engineering Contradiction:
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent consolidates multiple connector functions into a single manufactured unit. The terminal assembly is produced as one integrated component containing all terminal members, eliminating the need to manufacture and assemble separate female heads, middle plates, and backplane connectors, thereby reducing production costs while maintaining compatibility with multiple connector types.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector design incorporates universal terminal members that can interface with different connector standards (SAS, PSAS, PCIe) within a single device. This multi-functionality is achieved through the integrated terminal assembly that provides multiple pin configurations in one unit, reducing the need for multiple specialized connectors and lowering overall production costs.

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

3Reliability

If a traditional connector structure is used, then the connector can provide necessary connection functions, but the heat dissipation performance deteriorates

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent extracts the heat dissipation function from the traditional connector structure by introducing dedicated heat dissipation holes and a heat dissipation grating in the shell. This separates the connection function (performed by the terminal assembly) from the thermal management function (performed by the heat dissipation structures), allowing each to be optimized independently while improving overall heat dissipation performance.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A stack type female connector includes a terminal assembly, a main body, and a shell, wherein the terminal assembly is inserted in the main body. A board end is at a bottom part of the terminal assembly for being inserted on a PCB. A plugging end is at an anterior part of the terminal assembly for connecting a SSD interface. The terminal assembly has an upper terminal assembly and a lower terminal assembly, wherein both of the upper terminal assembly and the lower terminal assembly have a 40-pin terminal member and a 28-pin terminal member. The 28-pin terminal member is formed of a 15-pin terminal member, a 7-pin terminal member, and a 6-pin terminal member inserted in the terminal pedestal. The stack type female connector achieves a simplified structure, a lower production cost, and a better heat dissipation performance through an optimized design of the structure.
