Description

Technical Field

[0001] This utility model belongs to the field of testing fixture technology, and in particular relates to a wireless keyboard chip testing fixture. Background Technology

[0002] With the rapid development of wireless communication technology, the core control chip of wireless keyboards needs to meet stringent requirements such as multiple communication protocols (e.g., Bluetooth, 2.4GHz), low power consumption, and high signal stability. To ensure chip performance meets standards, a comprehensive test of the chip's electrical characteristics, signal quality, and functional logic is required during mass production using a dedicated test fixture. However, existing test fixtures have the following technical shortcomings: wireless chip testing needs to simulate a real working environment, but conventional fixtures have weak shielding designs, making them susceptible to external electromagnetic interference, leading to distorted signal error rate test results; uneven contact pressure between mechanical probes and chip contacts may cause fluctuations in contact resistance, affecting the accuracy of current and voltage parameter measurements.

[0003] For the reasons mentioned above, this utility model proposes a wireless keyboard chip testing fixture. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] See Figures 1 to 4 This utility model provides a technical solution: a wireless keyboard chip testing fixture, including a base plate 1 and a cover plate 2 connected to each other, and an adapter plate 6 disposed on the base plate 1. The base plate 1 is provided with a floating carrier plate 3; the cover plate 2 is provided with a floating pressure plate 5.

[0020] In this embodiment, a fixing plate 501 is provided between the pressure plate 5 and the cover plate 2.

[0021] In this embodiment, the pressure plate 5 is connected to the fixing plate 501 via a third elastic member 502.

[0022] In this embodiment, the pressure plate 5 is connected to the fixing plate 501 via a third elastic member 502.

[0023] In this embodiment, a limiting pin 103 is provided between the carrier plate 3 and the base plate 1.

[0024] In this embodiment, a positioning pin 302 is provided on the side of the carrier plate 3 opposite to the cover plate 2.

[0025] In this embodiment, a torsion spring 4 is provided at the connection between the cover plate 2 and the bottom plate 1.

[0026] In this embodiment, the end of the cover plate 2 away from the torsion spring 4 is provided with a handle 201 and a buckle 202.

[0027] In this embodiment, a first elastic element 2022 is provided between the buckle 202 and the cover plate 2.

[0028] In this embodiment, the base plate 1 is provided with a slot 101 that cooperates with the buckle 202.

[0029] In this embodiment, a second elastic element 301 is provided between the carrier plate 3 and the base plate 1.

[0030] Specifically, the chip is placed inside the carrier plate 3. The operator can hold the handle 201 to close the cover plate 2 onto the base plate 1. The positioning pin 302 and the positioning groove position the cover plate 2 and the base plate 1, ensuring accurate closing. Then, the latch 202 is used to fasten the cover plate 2 and the base plate 1. During the closing process, the pressure block 5 applies appropriate pressure to the chip. Under the pressure, the carrier plate 3 moves the chip downward, allowing the probe 7 to contact the detection point on the chip. After the detection is completed, the latch 202 is opened. The latch 202 springs open under the action of the first elastic element 2022, and the cover plate 2 automatically springs up a certain distance under the action of the torsion spring 4. The user can easily open the cover plate 2 by holding the handle 201. During use, the operation is convenient and avoids damage to the probe 7 and the chip.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
