Technical Field

[0001] The utility model relates to the technical field of automobile antennas, in particular to an automobile antenna plug-in test tool. Background Art

[0002] The car antenna is a device that intercepts the high-frequency radio waves emitted by the transmitter and transmits them to the receiver of the car radio, car phone or radio navigation equipment to demodulate the carrier. Some existing car antenna products with connectors need to be tested before leaving the factory. Specifically, the antenna product needs to be powered on and receive the signal it transmits to test whether there is any abnormality.

[0003] Some existing automotive antenna testing tools require manual insertion of the antenna product's PIN pin into the test head in the tooling, and then power-on testing. This type of tooling has the following problems: 1. It is easy for the antenna product to be inserted crookedly during insertion, and the stability of the test work cannot be guaranteed; 2. It is impossible to test whether the antenna product's PIN pin is bent. If the PIN pin is bent, the antenna product will operate unstably and the yield rate will be low.

[0004] The existing Chinese patent with the announcement number CN220154516U discloses an automobile antenna testing tool, including: a base body, on which is provided a fixing mechanism for fixing an antenna product and a test head for contacting and conducting with a PIN needle of the antenna product, the antenna product includes a base plate, the fixing mechanism includes a limiting slide corresponding to the base plate, a pressing block for pressing the base plate, and a driving part for driving the pressing block, and the base plate is slidably placed in the limiting slide; during operation, an external force causes the base plate of the antenna product to slide along the limiting slide, so that when the PIN needle contacts the spring probe of the test head, the pressing block is driven by the driving part to press the base plate for positioning.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the PIN needle of the device is slightly bent and pressed against the spring probe, normal power can be supplied, but the slight bending of the PIN needle cannot be detected, which affects the accuracy of the detection and needs to be improved; therefore, a car antenna plug-in test tool is proposed to address the above problems.
