Terminal-Movable Connector with Single Bolt Offset Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal-movable connectors require multiple parts and complex screwing operations to absorb positional variations, leading to increased size and part count.
Innovation Solution
A terminal-movable connector design featuring a terminal with a bolt insertion hole, a housing, a first support member for axial sliding, and a second support member with a nut, allowing a single bolt and nut set to absorb offsets and simplify terminal positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bus bar with two sets of bolts and nuts is used to absorb positional variation, then the terminal can be connected to the external cable, but the number of parts increases and the housing size must be increased
Solution Approach 1:
The invention extracts and eliminates the unnecessary bus bar component from the conventional structure. By directly connecting the terminal to the housing with a single bolt and nut, the bus bar relay structure is removed, reducing the number of parts while maintaining the ability to absorb positional variations through the terminal's own adjustability features
Solution Approach 2:
The invention segments the connection function by providing adjustable positioning features directly on the terminal body (such as positioning holes or slots) rather than relying on a separate bus bar structure. This allows the terminal itself to accommodate positional variations without requiring additional components
2Adaptability or versatility
If two sets of bolts and nuts are used for one bus bar, then the terminal can be connected at both ends, but the screwing operations become complex with different directions requiring multiple openings
Solution Approach 1:
The invention removes the bus bar intermediate structure that necessitates multiple screwing operations in different directions. By establishing a direct connection between the terminal and housing with a single bolt-nut assembly, the complexity of performing multiple screwing operations at different locations and angles is eliminated
Solution Approach 2:
The invention merges the terminal positioning and connection functions into a single integrated operation. The terminal's built-in adjustable features combine the alignment and securing functions, allowing both positioning and fastening to be achieved through one screwing operation rather than separate operations at multiple points
3Reliability
If a conventional terminal-movable connector structure is used, then the terminal can be fixed with a bolt and nut, but the overall size of the connector increases
Solution Approach 1:
The invention extracts and removes the bulky bus bar structure from the connector assembly. By eliminating this intermediate component and implementing a direct terminal-to-housing connection, the overall volume of the connector is reduced while maintaining reliable terminal fixation through the simplified single-bolt design

AI summary
A terminal-movable connector includes first support members which are disposed within an inner housing, and are fixed respectively to terminals in such a manner that each first support member is interposed between the inner housing and the corresponding terminal, and are slidable respectively in directions of axes of distal end portions of wires within the inner housing, and a second support member which is disposed in the inner housing, and supports the terminals in a manner to allow these terminals to be moved respectively in the axial directions of the distal end portions of the wires, and has nuts which are aligned respectively with bolt insertion holes formed respectively in electrical connection portions of the terminals.
