Wire-to-board connector set with assembled positioning structure

The present invention relates to a wire-to-board connector set with an assembled positioning structure, which particularly means that a wire end connector can be accurately engaged with a plate end connector by guiding the positioning structure, and then a card is used. The buckle device is fixedly assembled.

With the advent of the technological age, a wide variety of electronic products are constantly evolving. While the requirements of related devices are required to be improved, the requirements for the stability of electronic components are relatively increased to accommodate higher electrical performance and increasingly complex environments, and the connectors are mainly used as connections and signal transmission between electronic products. An important medium.

Wire-to-board connectors have been widely used in various types of mobile communication devices and various types of personal terminal devices to realize signal or power connection and transmission between functional devices and motherboards within such devices. The conventional wire-to-board connector assembly generally includes a plug connector and a socket connector, and the direction in which the wire-to-board connector combination plug connector is inserted can be divided into horizontal insertion and vertical insertion. Wherein, the horizontal insertion mode means that the plug connector is inserted into the socket connector in a direction parallel to the substrate, and the vertical insertion mode means that the socket connector is inserted into the socket connector from top to bottom in a direction perpendicular to the substrate. The vertical insertion method saves the space for insertion, but because of the height limitation, the insertion depth is short, making the quality of the connection less stable. Current vertical plug-in-to-board connectors usually have a snap on the plastic connector of the socket connector and the plug connector to increase the retention of the plug connector itself to prevent the plug connector from coming off. However, the retention provided by the buckle is limited, and the plug connector may be disengaged under the condition of gravity acceleration (such as falling on the ground), and the signal or power contact is not connected.

Therefore, how to strengthen the structure of the plug connector and the socket connector to prevent the inadvertent force (such as falling off the ground) is not easy to separate and avoid damage, which is still a problem to be solved.
