Terminal Insertion Gripper With Inclined-Groove Claw Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grippers for inserting terminals into housings require complex structures with horizontal and vertical movement mechanisms, occupying significant space and being unsuitable for applications with limited space.
Innovation Solution
A grasping device with a first gripper featuring a vertical groove and symmetrical inclined grooves forming a trumpet shape, allowing claws to move obliquely from a closed to an open state via a moving part and guide shaft, reducing the need for horizontal and vertical movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a horizontal movement mechanism and a vertical movement mechanism are both provided in the gripper, then the gripper can effectively insert terminals into housings, but the structure becomes complex and occupies significant space
Solution Approach 1:
The patent combines the horizontal and vertical movement mechanisms into a single integrated moving part that performs both functions simultaneously. The moving part includes a guide shaft for horizontal movement and inclined grooves that convert vertical motion into oblique claw movement, merging two separate mechanisms into one unified structure.
Solution Approach 2:
The moving part serves multiple functions: it guides horizontal movement of the claws, provides vertical movement capability, and controls the opening/closing action through inclined grooves. This single component performs what previously required separate dedicated mechanisms for each function.
2Reliability
If a horizontal movement mechanism and a vertical movement mechanism are both provided in the gripper, then the gripper can effectively insert terminals into housings, but the gripper occupies significant space
Solution Approach 1:
The patent combines the horizontal and vertical movement mechanisms into a single integrated moving part that performs both functions simultaneously. The moving part includes a guide shaft for horizontal movement and inclined grooves that convert vertical motion into oblique claw movement, merging two separate mechanisms into one unified structure.
Solution Approach 2:
The patent introduces oblique movement as a new dimension of motion. The inclined grooves convert vertical movement into oblique claw opening/closing motion, adding a diagonal dimension that efficiently combines vertical and horizontal functions without requiring separate mechanisms for each direction.
3Ease of operation
If both horizontal and vertical movement mechanisms are provided, then the gripper can release terminals after insertion, but the structure is not suitable for applications with limited space
Solution Approach 1:
The patent combines the horizontal and vertical movement mechanisms into a single integrated moving part that performs both functions simultaneously. The moving part includes a guide shaft for horizontal movement and inclined grooves that convert vertical motion into oblique claw movement, merging two separate mechanisms into one unified structure.

AI summary
A grasping device includes a first gripper for gripping a first component. The first gripper includes a mounting plate formed with a vertical groove extending in a vertical direction and a pair of inclined grooves symmetrically arranged on both sides of the vertical groove. A moving part of the first gripper is slidably engaged with the vertical groove to be able to move along the vertical groove. A pair of first claws of the first gripper are respectively slidably engaged with the pair of inclined grooves to be able to move along the pair of inclined grooves respectively. The pair of inclined grooves form a trumpet shape that flares upwards. The moving part comprises a guide shaft extending in a horizontal direction. Guide holes that are slidably fitted with the guide shaft are respectively formed in the pair of first claws.
