Surface Mount Connector With Detachable Housing For PCB Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surface mount electrical connectors lack the ability for detachable and reliable repeated disconnection between the conductive clamp and the housing, preventing the conducting wire or male end connector from being disconnected from the PCB.
Innovation Solution
A surface mount connector design comprising a bottom plate, conductive sheet, housing, and conductive clamp, where the housing is detachably mounted on the bottom plate with a mounting hole for the conductive clamp, allowing the conductive sheet to be inserted into the clamp for electrical connection and disconnection, facilitating easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductive clamp is directly welded to the PCB without a detachable housing, then the electrical connection is simple and reliable, but the conducting wire or male end connector cannot be disconnected from the PCB
Solution Approach 1:
The connector is divided into separate components: a housing that is detachably mounted on the bottom plate, a conductive clamp disposed in the housing, and a bottom plate welded to the PCB. This segmentation allows the housing and conductive clamp to be detached as a unit from the bottom plate, enabling the conducting wire or male end connector to be disconnected from the PCB while maintaining reliable electrical connection during use
Solution Approach 2:
The conductive clamp is disposed within the housing, which is detachably mounted on the bottom plate. This nested structure allows the conductive clamp to be held securely in the housing during operation, while the entire housing-clamp assembly can be detached from the bottom plate when disconnection is needed, resolving the contradiction between secure connection and detachability
2Ease of manufacture
If the housing and conductive clamp are made as a whole for easy assembly, then the assembly process is simplified, but the conductive clamp may be blocked by other electronic elements on the PCB making accurate mounting difficult
Solution Approach 1:
The connector system is segmented into a bottom plate (welded to PCB), a housing (detachably mounted on bottom plate), and a conductive clamp (disposed in housing). This segmentation allows the housing and conductive clamp to be assembled as a unit for ease of manufacture, while the detachable housing provides access and positioning advantages during mounting operations, preventing the conductive clamp from being blocked by other electronic elements on the PCB
3Volume of moving object
If the conductive clamp is made small to fit in the mounting hole, then the connector size is reduced, but the clamping force and electrical contact area are limited
Solution Approach 1:
The conductive clamp is nested within the housing, which provides structural support and leverage. The housing acts as a mechanical advantage system that amplifies the clamping force applied to the conductive clamp, allowing a small conductive clamp to generate sufficient clamping force while maintaining compact overall connector size

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables reliable connection and disconnection of the conducting wire to the PCB, improving assembly efficiency by allowing the housing to drive the conductive clamp onto the bottom plate from top to bottom, overcoming the challenge of small dimensions and blocked access.
Implementation Method 1
a bottom portion of the conductive sheet runs through the bottom wall, so that the bottom portion can be welded into a PCB

AI summary
A surface mount connector comprises a bottom plate having a bottom wall, a conductive sheet disposed on the bottom plate and having a bottom portion running through the bottom wall and weldable to a PCB, a housing detachably disposed on the bottom plate and provided with a mounting hole corresponding to the conductive sheet, a conductive clamp disposed in the mounting hole, and a clamping piece portion adaptive to the conductive sheet disposed on the conductive clamp. The housing is capable of driving the conductive clamp to the bottom plate from top to bottom, so that the conductive sheet can insert into the clamping piece portion. The conductive clamp is electrically connected to the conductive sheet. The housing can drive the conductive clamp to detach from the bottom plate from bottom to top, so that the conductive clamp can disconnect from the conductive sheet.
