Abstract

The utility model provides a connector reed anti-withdrawal structure, which comprises an anti-withdrawal baffle block. The anti-withdrawal baffle block is composed of an upper row of discharge pin slots, a middle row of discharge pin slots and a lower row of pin blank holders. The anti-withdrawal baffle block is provided with a left side surface and a right side surface, wherein the left side surface or the right side surface is provided with a slope bulge part. According to the technical scheme of the utility model, due to the extra adoption of the anti-withdrawal baffle block, once some base pin is inclined during the assembling process, the inclined base pin is hard to be inserted into the weld hole of a circuit board under the spacing effect of the anti-withdrawal baffle block. In this way, the entire body of the electric connector cannot be inserted into the weld hole. Then the inclined base pin is corrected to ensure the assembly quality. During usage, when some contact head of the connector is pressed by an inclined external inserting pin, the inserting pin can be corrected the form thereof by itself to be smoothly inserted into the weld hole under the effect of the anti-withdrawal baffle block. Or, the inserting pin cannot be inserted into the weld hole at all and then is judged to be inclined or not by operators.
