Connector Plug Baffle Plates Guide Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In narrow spaces, existing electrical connector plugs are prone to being inserted obliquely due to cable stress, leading to a risk of PIN collapse when mating with conductive terminals.
Innovation Solution
The design incorporates a plug with an insulating body featuring baffle plates and limiting grooves that guide insertion, preventing oblique insertion and ensuring accurate alignment with the socket, thereby reducing the risk of PIN collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the plug is made very short to fit narrow spaces, then the space requirement is improved, but the plug becomes easy to insert obliquely due to cable stress, increasing the risk of PIN collapse
Solution Approach 1:
The limiting grooves are pre-formed on the insulating body to guide the insertion process before the actual mating occurs. These grooves create predetermined paths that steer the plug into correct alignment with the socket, preventing oblique insertion from the outset
Solution Approach 2:
The limiting grooves act as an intermediary guiding mechanism between the plug and socket. They provide a mediating structure that facilitates proper alignment and insertion orientation, reducing the direct harmful interaction between cable stress and the circuit board
2Ease of operation
If the plug is inserted obliquely due to cable stress, then the insertion process becomes easier in narrow spaces, but the circuit board mates with contact parts incorrectly, causing PIN collapse
Solution Approach 1:
The limiting grooves are designed with asymmetric geometries that do not allow symmetric or random insertion orientations. The grooves are positioned and shaped to permit insertion only in the correct orientation, preventing oblique or reversed insertion while maintaining ease of operation

AI summary
Provided are a plug and an electrical connector component. The plug includes an insulating body, a circuit board fixed to the insulating body, and a cable electrically connected with the circuit board and extending backwards from the insulating body. The insulating body includes a body part and a mating part which extends forwards from the body part; the circuit board has an inserting part that protrudes forwards out of the mating part; metal contact pieces are distributed on upper and lower surfaces of the inserting part; the insulating body is provided with a pair of baffle plates extending forwards from the body part; a pair of the baffle plates are respectively arranged on left and right sides of the mating part; and a limiting groove configured to guide the insertion of the plug with the socket is formed between each of the baffle plates and the mating part.
