Abstract

A testing fixture includes a driving component, a supporting component, a first resilient component, a plurality of connecting components and a plurality of testing components. The driving component includes a board and a sleeve. A guiding slot is formed on a lateral wall of the sleeve. The supporting component includes a base, a bridging pillar and a guiding pin. The base includes a plurality of pivot hole structures. The bridging pillar is disposed on a surface of the base and movably disposed inside the sleeve. The guiding pin is disposed on a lateral surface of the bridging pillar and slidably passing through the guiding slot. The first resilient component is disposed on the bridging pillar and contacts against the sleeve, so as to move the base relative to the board. The connecting components pivot to the pivot hole structures, and each testing component is disposed on the corresponding connecting component.

First claim

What is claimed is:

1. A testing fixture applied to the multi-touch function, the testing fixture comprising:
a driving component, the driving component comprising:
a board; and
a sleeve structure disposed on the board, a guiding slot being formed on a lateral wall of the sleeve structure;

a supporting component movably disposed on the driving component, the supporting component comprising:
a base, the base comprising a plurality of pivot hole structures;
a bridging pillar disposed on an upper surface of the base and movably disposed inside the sleeve structure; and
a guiding pin disposed on a lateral surface of the bridging pillar and slidably passing through the guiding slot;

a first resilient component disposed between the base and the sleeve structure for driving a movement of the base relative to the board;
a plurality of connecting components respectively pivoting the corresponding pivot hole structures of the base; and
a plurality of testing components respectively disposed on the corresponding connecting components.

2. The testing fixture of claim 1 , wherein the first resilient component is disposed on the bridging pillar, and two ends of the first resilient component respectively contact against the sleeve structure and the base.

3. The testing fixture of claim 2 , wherein the first resilient component is a compressive spring or a torsional spring.

4. The testing fixture of claim 1 , wherein the base comprises a plank structure and a joint structure, the plurality of pivot hole structures is disposed on the joint structure, and the joint structure is disposed on a bottom of the plank structure.

5. The testing fixture of claim 1 , wherein the testing component comprises a fixing hole and a contacting wall, the testing component passes through a piercing hole on the connecting component, a fixing component is utilized to pass through the fixing hole, so that a movement of the testing component relative to the connecting component is constrained by the contacting wall and an assembly of the fixing hole and the fixing component.

6. The testing fixture of claim 5 , further comprising:
at least one second resilient component disposed on the testing component, two ends of the second resilient component respectively contacting against the connecting component and the contacting wall.

7. The testing fixture of claim 6 , wherein the second resilient component is a compressive spring.

8. The testing fixture of claim 6 , further comprising:
at least one third resilient component, two ends of the third resilient component being respectively disposed on the base and the connecting component.

9. The testing fixture of claim 8 , wherein the third resilient component is a bending piece or a torsional spring.

10. The testing fixture of claim 1 , wherein the guiding slot is a linearly inclined slot, and a structural direction of the linearly inclined slot substantially intersects an axial direction of the sleeve structure.

11. The testing fixture of claim 1 , wherein the guiding slot is a curved arc slot, tangential directions of two ends of the curved arc slot are substantially parallel and perpendicular to an axial direction of the sleeve structure.

12. The testing fixture of claim 1 , wherein the guiding slot is a spirally annular slot, the spirally annular slot surrounds the sleeve structure, and a height difference is formed between two ends of the spirally annular slot.

13. The testing fixture of claim 1 , further comprising:
a transmission unit disposed on the driving component for moving the supporting component upwardly and downwardly, so as to press the plurality of testing components to contact an object.
