Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a Mini FAKRA connector. Background Art

[0002] In the related technology, FAKRA connector is a connector component widely used in automobiles, generally used in GPS positioning systems, remote control systems, car phone systems, satellite radios and car Internet access, etc. Mini FAKRA connector is a connector used for car wireless communication and car multimedia systems. It is a variant of the FAKRA connector series. Compared with the standard FAKRA connector, the Mini FAKRA connector has a smaller size and higher density, which is suitable for applications with limited space and high-density wiring.

[0003] When testing the current Mini FAKRA connector, the size of the female connector just matches the device being tested. Because of its small size, higher accuracy is often required during insertion to ensure a normal connection. This requires the female connector to make more precise position adjustments during insertion, which significantly increases the time spent and is not conducive to efficient testing. At the same time, the previous Mini FAKRA interface was tested through a wiring harness. Because there are buckles and no installation positioning, automatic quick plugging and unplugging cannot be achieved. The buckle needs to be manually opened during testing, which is not conducive to efficient testing. Therefore, how to improve the testing efficiency of the Mini FAKRA connector has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a Mini FAKRA connector, which can improve the test efficiency of the Mini FAKRA connector.

On the one hand, when it is necessary to access the device through the male shell, because the size of the first sliding portion of the male shell matches the external device interface, because the first inclined surface is provided, and the end face size of the guide portion is smaller than the external device interface, the male shell and the inner core can be connected to the external device interface, so that the guide portion has a guiding function, thereby reducing the difficulty of adjusting the position of the male shell when the device is connected, and the connection efficiency is high, thereby reducing the time consumption and improving the efficiency of device testing. On the other hand, in order to further improve the guiding effect, a second sliding portion and a second inclined surface provided on the second sliding portion are also provided.
