Short-Terminal Connector Housing for Tolerance Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-voltage connectors face challenges in aligning a short terminal with electrodes in a counterpart connector due to manufacturing tolerances, making it difficult to establish a reliable connection.
Innovation Solution
A connector design where a second housing with a short terminal is attached to the first housing and retained by a front holder, allowing the second housing to be displaceable in a direction intersecting the fitting direction, ensuring the short terminal can face the counterpart connector effectively.

1Reliability
If a short terminal is embedded in the housing to detect fitting state, then the fitting state can be detected, but the alignment between the short terminal and the electrodes of the counterpart connector becomes difficult due to manufacturing tolerances
Solution Approach 1:
The second housing is made displaceable relative to the first housing in a direction intersecting the fitting direction. This dynamic structure allows the short terminal to automatically adjust its position to compensate for manufacturing tolerances, ensuring reliable alignment with the counterpart connector's electrodes while maintaining fitting state detection capability
Solution Approach 2:
The connector is divided into two separate housings: the first housing containing the terminal fitting and the second housing containing the short terminal. This segmentation allows independent positioning and adjustment of each component, enabling the second housing to be retained by the front holder in a displaceable state to facilitate alignment between the short terminal and electrodes

AI summary
A connector includes: a terminal fitting; an electric wire connected to the terminal fitting; a first housing in which the terminal fitting is stored, the first housing constituting a fitting part with a counterpart connector; a seal member disposed so as to surround an outer periphery of the first housing; a front holder mounted on the first housing so as to prevent the seal member from coming out from the first housing; and a second housing including a short terminal, the short terminal being configured to allow a fitting state with the counterpart connector to be detected. The second housing is attached to the first housing and retained by the front holder in a state in which the second housing is displaceable in a direction intersecting a fitting direction with the counterpart connector in a posture in which the short terminal faces the counterpart connector.
