Electrical Connector Assembly for Independent Sub-Connector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face difficulties in mounting multiple sub-connectors to a circuit board simultaneously due to shared insulating bodies, leading to low yield rates and a need for improved mating accuracy with different electronic components.
Innovation Solution
The electrical connector design includes an outer insulating body with an accommodating space and a first sub-connector with pre-mounted terminals, where the outer insulating body is sleeved onto the sub-connector, and an identification connector with conductive terminals connected by a conductive element to transmit identification signals to the circuit board, simplifying the mounting process and enhancing identification functionality.

Engineering Contradiction Analysis
1Volume of moving object
If multiple sub-connectors share a common insulating body, then the connector structure is compact, but the mounting difficulty increases and yield rate decreases
Solution Approach 1:
The patent divides the connector into independent sub-connectors (first sub-connector, second sub-connector, etc.), each with its own insulating body and conductive terminals. This segmentation allows each sub-connector to be mounted independently on the circuit board, eliminating the mounting difficulties associated with shared insulating bodies while maintaining a compact overall structure through the outer insulating body's accommodating spaces.
2Productivity
If sub-connectors are mounted simultaneously to the circuit board, then all terminals are connected at once, but the mounting process becomes complex and yield rate drops
Solution Approach 1:
The patent performs preliminary mounting of conductive terminals to the circuit board before assembling the outer insulating body. The mounting steps include: (1) mounting first conductive terminals of the first sub-connector to the circuit board, (2) mounting second conductive terminals of the second sub-connector to the circuit board, and only then (3) mounting the outer insulating body. This preliminary action simplifies the mounting process and improves yield rate by avoiding complex simultaneous mounting operations.
3Ease of manufacture
If connectors have identical appearance, then manufacturing is simplified, but mating accuracy with different electronic components decreases
Solution Approach 1:
The patent applies local quality by providing different identification features (protrusions or recesses) at specific locations on different sub-connectors while keeping the overall connector appearance identical. The first sub-connector has a first identification feature and the second sub-connector has a second identification feature, allowing electronic cards to be accurately matched to the correct connector position without complicating the overall manufacturing process.

AI summary
An electrical connector includes an outer insulating body, a first sub-connector, an identification connector and a terminal module. The outer insulating body includes an accommodating space and a second slot located beside of the accommodating space. The first sub-connector includes a first insulating body and a number of first terminals. The first insulating body includes a first slot. The outer insulating body is sleeved on the first sub-connector with the first insulating body accommodated in the accommodating space. Such arrangement simplifies the mounting of the electrical connector. A method for mounting the electrical connector is also disclosed.
