Positioning device

Abstract

This invention provides a positioning device for connecting and positioning a substrate and an interface card. The positioning device includes a positioning base mounted on the substrate, an operating member pivotally connected to the positioning base, and elastic members respectively abutting against the positioning base and the operating member. When the operating member is not pushed by an external force, at least a portion of one end of the interface card is positioned between the locking portion of the operating member and the base of the positioning base, maintaining the interface card in a positioned state. When the operating member is pushed by an external force, the locking portion rotates relative to the base, releasing the interface card from the positioned state. This allows the interface card to be stably positioned by the positioning device, effectively preventing detachment, shaking, or poor contact caused by external forces or vibrations, thereby improving the stability of the electrical connection.

Claims

1. A positioning device for connecting and positioning a substrate and an interface card, comprising: A positioning base includes: a base having a receiving space on one side; A fixing part is disposed on the bottom side of the base and fixed to the substrate; a first pivot part is disposed on the base and located on opposite sides of the accommodating space; an operating member is pivotally connected to the positioning seat, comprising: a body; a second pivot part is disposed on the bottom side of the body and at least partially extends into the accommodating space and is pivotally connected to the first pivot part; a latching part is disposed on one side of the body and adjacent to the top end of the body; and an operating part is disposed on the top end of the body, the top side of which forms a force-bearing surface to drive the second pivot part; and an elastic member is at least partially accommodated in the accommodating space, the two ends of which respectively abut against the base and the body; wherein, when the operating member is not pushed by an external force, a positioning space is formed between the latching part and the base to position at least a portion of one end of the interface card, so that the interface card is maintained in a positioning state; When the operating member is pushed by an external force, the insert portion rotates relative to the base to release the interface from the positioning state.

2. The positioning device as claimed in claim 1 further includes a fixing member comprising: a main body having a fixing hole through which the fixing portion passes; and an extension disposed on the bottom side of the main body and assembled into an assembly hole of the substrate.

3. The positioning device as described in claim 2, wherein, The main body further includes: a positioning foot disposed on the main body and extending toward the substrate; the substrate has a positioning hole disposed on one side of the assembly hole, such that the positioning foot at least partially extends therein.

4. The positioning device as claimed in claim 2, wherein, The extension further includes: a limiting portion disposed on one of the bottom side or the opposite inner side of the extension and extending toward the fixing hole; the fixing portion further includes: a guide opening disposed on the side of the fixing portion and connected to its bottom edge; a positioning groove disposed on the side of the fixing portion and adjacent to the bottom side of the base; and a guide path communicating from the guide opening to the positioning groove; wherein the limiting portion has a height misalignment from the guide opening along the guide path to the positioning groove.

5. The positioning device as claimed in claim 2, wherein, The base further includes: a protrusion located at the periphery of the bottom side of the base; the body further includes: an opening located on the side of the body and corresponding to one side of the protrusion, and having a guide slope for receiving the protrusion into the opening.

6. The positioning device as claimed in claim 1, wherein, The first pivot portion further includes: a pivot hole and a pivot shaft, and the second pivot portion has a shaft hole; wherein the shaft hole corresponds to the pivot hole, and the pivot shaft passes through the pivot hole and the shaft hole.

7. The positioning device as claimed in claim 1, wherein, The elastic member includes: an annular portion received in the receiving space; a first support arm extending outward from the annular portion; and a second support arm extending outward from the annular portion, with its extension direction different from that of the first support arm; the body further includes: an abutting surface formed on the bottom side of the body and corresponding to one side of the receiving space, such that the end of the second support arm abuts thereon; the base further includes: an abutting groove provided on one side of the base and between the fixing portion and the receiving space, such that the end of the first support arm extends into and abuts thereon.

8. The positioning device as claimed in claim 1, wherein, The base has a support surface on its top side; the insert portion has a clamping slot corresponding to the support surface; wherein, when the operating member is not pushed by an external force, at least a portion of one end of the interface card is clamped between the support surface and the clamping slot, so that the interface card is maintained in a positioning state.

9. The positioning device as claimed in claim 1, wherein, The base further includes: a locking portion disposed on the top side of the base; the locking portion further includes: a receiving opening disposed on one side of the locking portion, and corresponding to the locking portion, the receiving opening has a guide surface; wherein, when the operating member is not pushed by an external force, the locking portion is at least partially received in the receiving opening; when the operating member is pushed by an external force, the receiving opening is separated from the locking portion by a distance.

10. The positioning device as claimed in claim 1, wherein, The projected length of the stress-bearing surface is between 5 mm and 15 mm.
