L-Shaped Crimp Terminal Layout to Avoid Crimping Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors with L-shaped terminals face interference with crimping devices due to protruding terminal connection parts, preventing proper crimping, and require excessive space for connection, leading to larger apparatus sizes.
Innovation Solution
The crimp terminal design includes a crimped part with a barrel piece protruding in one direction and a terminal connection part extending orthogonally, with a coupling part bent around an axis, allowing for integration with a carrier that aligns with the crimping device's anvil, reducing interference and enabling efficient crimping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an L-shaped terminal is used to enable easy connection to counter connectors, then the ease of operation is improved, but the terminal connection part protrudes largely from the carrier part, causing interference with the crimping device and making crimping impossible
Solution Approach 1:
The terminal connection part is extended in a direction substantially perpendicular to the extending direction of the carrier part, changing the spatial orientation from in-plane to out-of-plane. This dimensional change allows the terminal connection part to protrude laterally rather than forward, avoiding interference with the crimping device's anvil while maintaining easy connection capability
Solution Approach 2:
The terminal is designed with asymmetric geometry where the terminal connection part extends perpendicular to the carrier part's length direction, creating an L-shaped configuration. This asymmetric design optimizes both connection ease and crimping feasibility by positioning the terminal connection part in a direction that avoids crimping device interference
2Ease of operation
If both connectors are arranged on the same axis to enable connection, then the connection is achieved, but a wide space is required and the apparatus size becomes large
Solution Approach 1:
By extending the terminal connection part in a direction perpendicular to the carrier part's extending direction, the connector can be connected to a counter connector mounted on an electrical board without requiring the connectors to be arranged on the same axis. This spatial reconfiguration reduces the space required and allows for more compact apparatus design

AI summary
A crimp terminal includes a crimped part crimped to a cable; and a terminal connection part provided to be bent with respect to the crimped part. The cramped part includes: a base part on which the cable extending in a first axial direction is placed; and a barrel piece protruding from the base part in one direction of a second axial direction orthogonal to the first axial direction, and caulked to be crimped to the cable. The terminal connection part is extended in one direction of a third axial direction orthogonal to the first axial direction and the second axial direction.
