Description

Technical Field

[0001] The utility model relates to the field of connector structures, in particular to a connector which is convenient for flatness detection. Background Art

[0002] The thickness of the mating card of the existing GEN-Z series connector is 1.57mm, and the height dimension of the mating slot for plugging the mating card on the female connector is 1.76mm. Sufficient space is reserved inside the product to facilitate product structure design. After the connector is manufactured, it is necessary to detect the flatness of the connector pins. The pins are arranged in two rows at the lower end of the connector, and the CCD camera detects the lower position of the pins. When the front row of pins is detected, the light source is illuminated from one side of the mating slot, and the light is irradiated on the pins from the lower side of the connector shell, thereby providing fill light for the detection. However, since the front end face of the connector shell is long from the position of the pins, the light is blocked by the connector shell, and it is difficult for the light to be effectively irradiated on the pins, resulting in the detection environment being too dark and the flatness detection accuracy being low. Therefore, it is necessary to produce a connector that is easy to detect flatness to solve the above problems. Utility Model Content

[0020] The mating card is inserted into the mating slot 111 of the connector, and the upper and lower sides of the mating card are electrically connected to the upper terminal 03 and the lower terminal 02 respectively. By opening an air avoidance slot 112 at the bottom of the plastic shell 01, when the flatness of the terminal pin position is detected, the distance between the bottom end face of the plastic shell 01 and the pin can be greatly shortened, so that light can pass through the air avoidance slot 112 to fill in the pin, thereby improving the fill-in light effect and further improving the accuracy of the pin flatness detection.
