BTB Connector Mounting Structure for Thin Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting structures for board-to-board (BTB) connectors in mobile terminals either fail to maintain stability due to space occupation by pads or dabbers in removable structures or result in an out-of-shape battery shell when compressed in all-in-one structures, hindering the thin design and assembly of mobile terminals.
Innovation Solution
A mounting structure featuring a mounting body with an inserting portion and a hook attached to the BTB connector, where the inserting portion connects to a shielding case and the hook engages the main board, ensuring proper alignment and compression without occupying excessive space, allowing for stable assembly and preventing over-compression issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pad or long dabber is used to fix the BTB connector in a removable structure, then the connector can be mounted, but the mounting structure occupies large space and cannot detect connection stability
Solution Approach 1:
The mounting structure is divided into multiple functional components: a first mounting portion that hooks to the host front shell, a second mounting portion that contacts the battery shell, and a compression portion that applies force to the BTB connector. This segmentation allows each part to perform its specific function efficiently while minimizing overall space occupation.
Solution Approach 2:
The mounting structure transitions from a planar pad/dabber configuration to a three-dimensional structure with vertical hooks and compression elements. The first mounting portion hooks downward from the top surface, while the second mounting portion contacts the battery shell from above, creating a vertical compression path that reduces horizontal space requirements.
2Reliability
If screws are used to compress the BTB connector in a removable structure, then connection stability can be maintained, but the mounting structure becomes complex and occupies space
Solution Approach 1:
The screw fastening mechanism is extracted and replaced with an elastic compression mechanism. The mounting body itself provides the compression force through its elastic deformation, eliminating the need for separate screws and complex fastening structures while maintaining reliable connection stability.
Solution Approach 2:
The mounting structure uses its own elastic properties to provide compression force. The elastic mounting body automatically adjusts and maintains compression on the BTB connector through its inherent elasticity, without requiring external fastening components or complex adjustment mechanisms.
3Reliability
If the BTB connector is compressed in an all-in-one structure, then connection can be established, but the battery shell becomes out of shape
Solution Approach 1:
The mounting structure acts as an intermediary between the BTB connector and the battery shell. It provides a dedicated compression path through its elastic mounting body, preventing direct compression of the battery shell while still achieving reliable connector connection. The mounting structure absorbs the compression forces.
Solution Approach 2:
The compression force is applied locally at specific contact points through the mounting structure rather than distributing pressure across the entire battery shell. The first mounting portion hooks to the host front shell at one location, while the second mounting portion contacts the battery shell at another location, creating a localized compression path that preserves battery shell shape.
4Reliability
If a traditional mounting structure is used, then the BTB connector can be fixed, but the mobile terminal cannot achieve thin design
Solution Approach 1:
The mounting structure is nested within the existing mobile terminal assembly. The first mounting portion hooks to the host front shell, the second mounting portion contacts the battery shell, and the compression portion engages the BTB connector, creating a compact nested arrangement that fits within the thin profile of modern mobile terminals without adding excessive thickness.

AI summary
The present invention provides a mounting structure of mounting a BTB connector to a mobile terminal, the mounting structure of mounting the BTB connector to the mobile terminal is formed on the BTB connector and a mounting body is attached to the BTB connector, a front end of the mounting body comprises an inserting portion that is inserted into and connected to a shielding case, and a back end of the mounting body comprises at least one hook that hooks an edge of a main board, height of each of the inserting portion and the hook is arranged under the mounting body, both of the inserting portion and the hook abut a top ending surface of the main board, and a distance between a bottom ending surface of a compressing portion of the mounting body and the top ending surface of the main board is equal to a distance between a top ending surface of the BTB connector and the top ending surface of the main board. The present invention solves an issue in the removable structure of conventional technologies, where the stable maintenance of the mobile terminal connecting with the BTB connector cannot be detected and the space is occupied by the pad or the long dabber, and that goes against thin mobile terminal, and solves an issue in the all-in-one structure where the BTB connector cannot be compressed and the battery shell is out of shape by being over compressed.
