Connector Peg Press-Fitting Position Regulating Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing peg press-fitting structures for connectors often result in unreliable grounding connections due to misalignment of press-fitting positions, leading to decreased contact reliability between the grounding member of the cable side connector and the pegs.
Innovation Solution
A peg press-fitting structure with a press-fitting position regulating projection, such as an obliquely cut-and-raised piece, is provided at the base end of the peg to ensure accurate positioning by abutting against the end wall of the housing, preventing excessive insertion and stabilizing the contact position for improved grounding connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pegs are positioned only by recognizing that the pegs project from the housing, then the positioning process is simple, but the press-fitting positions may become out of the appropriate range, decreasing grounding connection reliability
Solution Approach 1:
The peg itself serves dual functions: it provides grounding connection and simultaneously regulates its own press-fitting position through the press-fitting position regulating projection. The projection on the peg automatically abuts against the end wall during press-fitting, eliminating the need for separate positioning mechanisms while ensuring accurate positioning and reliable grounding connection.
2Reliability
If the pegs are excessively pushed into the peg attaching slots, then the pegs are securely fixed, but the contact positions where grounding members contact the pegs are displaced, decreasing grounding connection reliability
Solution Approach 1:
The press-fitting position regulating projection is pre-configured on the peg at a specific position closer to the base end than the press-fitted portion. During press-fitting, this projection automatically abuts against the end wall of the housing, preliminarily determining the correct press-fitting position before the grounding member contact positions are established, thereby preventing displacement and ensuring reliable grounding connection.
3Manufacturing precision
If a press-fitting position regulating projection is added to the peg, then the press-fitting position is accurately regulated, but the device complexity increases
Solution Approach 1:
The press-fitting position regulating function is merged with the peg structure itself. The press-fitting position regulating projection is integrated into the peg as a single component, combining the grounding function and position regulation function in one element. This eliminates the need for separate positioning mechanisms while achieving accurate press-fitting position control.

AI summary
A peg press-fitting structure for a connector includes a peg which is made from a metal plate to fix a housing of the connector to a circuit board, and which is attached to the housing by being press-fitted from the distal end of the peg into a peg attaching slot of the housing of the connector. The housing is provided with an end wall where an entrance of the peg attaching slot opens. A press-fitting position regulating projection, which regulates the press-fitting position of the peg by abutting against the end wall of the housing where the entrance of the peg attaching slot opens, is provided closer to the base end of the peg than a press-fitted portion of the peg that is press-fitted into the peg attaching slot.
