Description

Technical Field

[0001] The utility model relates to the field of testing technology, in particular to a fixture for triggering a radio frequency SAR-sensor function. Background Art

[0002] Mobile terminals such as mobile phones and tablets are widely used in people's daily lives, and the terminals are usually close to the human body. In order to keep the impact of electromagnetic waves radiated by the terminal antenna on the human body within a safe range, CE certification and FCC certification have stricter requirements for SAR (Specific Absorption Rate). In order to ensure that the terminal meets the SAR index requirements after leaving the factory, the SAR index of the terminal needs to be tested before leaving the factory.

[0003] A SAR sensor is a highly sensitive capacitive proximity sensor that accurately detects the proximity of a mobile device to a human body. The SAR sensor operates based on its sensing capability. When a person approaches, it reduces the device's transmit power, thereby reducing radiation. Mobile phone sensors typically consist of a sensing element and a conversion element, converting environmental or phone behavior into electrical signals.

[0004] In the existing technology, during the testing phase, the signal transmission between the SAR sensor and the main processor is triggered by simulating the approach and distance of objects (such as human bodies, metal materials, etc.) in the use scenario of the mobile terminal. Different models of mobile terminals require manual use of fixtures of different sizes to trigger, and because the triggering positions are different, manual adjustment of the positions is required, resulting in low test efficiency and long product testing cycles.

[0032] See also Figure 1-Figure 4 A fixture for triggering a radio frequency SAR sensor function includes a positioning member 1 and a sensing component. The sensing component is connected to the positioning member 1. A driving device drives the positioning member 1 to move or rotate, thereby driving the sensing component to trigger the SAR of a mobile terminal.

[0045] Adaptively, in order to improve the applicability of this embodiment, the distance between the first test plate 21 and the second test plate 22 is adjustable.
