Electric Connector Housing Protrusion for Bracket Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connectors face issues with damage to the housing and deformation of brackets due to misalignment during assembly, particularly in miniaturized electronic devices where space constraints are severe.
Innovation Solution
The electric connector design features a first housing with a recess and a second housing with a projection, where the projection is disposed perpendicular to the bracket, and a protrusion is formed on the first housing closer to the fitting side, allowing for guided alignment and elastic deformation to prevent damage and deformation during fitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector is miniaturized to reduce size, then the area occupied on circuit board is reduced, but the housing becomes more susceptible to damage and brackets to deformation during assembly
Solution Approach 1:
The protrusion is formed in advance on the housing, positioned to make contact with the bracket before the main body of the housing contacts the bracket during assembly. This preliminary contact guides the insertion process and prevents misalignment that would cause damage or deformation.
Solution Approach 2:
The protrusion acts as an intermediary element between the housing and the bracket. It facilitates proper alignment and contact sequence, mediating the interaction between the miniaturized housing components to prevent direct harmful contact between the housing and bracket during assembly.
2Ease of operation
If misalignment occurs during assembly, then fitting is simplified, but the bracket deforms or the housing is scraped
Solution Approach 1:
The protrusion makes preliminary contact with the bracket to establish proper alignment before the main housing body engages with the bracket. This ensures that even if initial positioning is imperfect, the protrusion guides the components into correct alignment during the fitting process.
Solution Approach 2:
The protrusion serves as a cushioning element that absorbs and distributes misalignment forces during assembly. By contacting the bracket first, it prevents direct impact and scraping between the housing and bracket, protecting both components from damage even when misalignment occurs.

AI summary
Provided is an electric connector capable of preventing damage to a housing and deformation of a bracket even if it is miniaturized. An electric connector (10) according to the present disclosure includes: a first connector (20) having a first housing (30) with a recess (35) formed in a first surface and a first bracket (54) held by the first housing (30) while facing the first surface; and a second connector (60) fitted with the first connector (20), the second connector having a second housing (70) with a projection (76) fitted into the recess (35), the projection being formed on a second surface corresponding to the first surface, and a second bracket (94) held by the second housing (70) while facing the second surface and electrically connected to the first bracket (54). After the first housing (30) and the second housing (70) are fitted together, the projection (76) is disposed such that a side face along a direction perpendicular to the first surface faces the first bracket (54) or the second bracket (94), and the first housing (30) has a protrusion formed continuous with the first surface and located closer to the fitting side than the first bracket (54).
