Description

Locking structure of connector assembly

This creation provides a locking structure for the connector assembly, especially when the plug connector is not locked, the pivotal handle can be opened through the shielding shell, so that the handle is not buckled on the metal of the socket connector When the plug connector is combined with the socket connector, the handle can be turned to generate elastic reset, so that the handle can be buckled on the metal shell to facilitate the locking or unlocking operation.

According to, general connectors are used in the connection of electronic signals and power supplies and their accessory accessories. The main function is to provide connections between various electronic devices or equipment, and to ensure accurate signal transmission. The connectors follow their applications. , Power and use environment, etc., it has developed a variety of different types, and can be widely used in consumer electronic products such as computers, notebooks, smart phones, or household appliances, telecommunications and communication equipment, etc. , And because the design of electronic products nowadays tends to be light, thin, short and small, the internal connectors of various electronic products need to be greatly reduced accordingly. In contrast, the connection of thin connectors and ordinary wires or flexible circuit boards And fixation is bound to be more difficult.

Furthermore, as the volume of electronic products is becoming thinner and thinner, the components of the internal mounting circuit boards of the electronic products need to be more precise and smaller, and the overall structural strength needs to be strengthened accordingly. General connectors (such as: Board-to-board connectors or wire-to-board connectors, etc.) are usually advantageous A male connector and a female connector are used for mating and docking, and the signal or power can be transmitted to the control circuit through the circuit board to perform the corresponding operation function, but when the male connector is docked with the female connector In order to reduce the height of the overall structure, most of them are assembled by fitting. The body of the male connector is first inserted into the fitting space of the female connector, and the convex buckle of the body is buckled on the base. After being in the buckle groove, the plurality of conductive terminals of the body can be resisted and contacted with the corresponding contact terminals on the base to form an electrical connection, thereby realizing two parallel opposite circuit boards, or between a flexible circuit board, a cable and a circuit board The electrical connection.

However, because the main body and the base are integrally formed of a resin made of resin, the method of interlocking the main body and the base by using the convex buckle and the buckle groove will cause mutual wear due to multiple insertion and removal butting, and cause The overall mating force is reduced, and even excessive compression during assembly or disassembly can easily cause damage to the glue or structural damage. Moreover, when docking, the plurality of conductive terminals and the plurality of contact terminals are all through a single side The butt joints with frictional contact fit each other, and the positioning effect of each other is not ideal. Once it is affected by external force collision or touch, it is easy to cause looseness or separation between the male end connector and the female end connector, resulting in the male end connector The signal transmission with the female connector is unstable.

Therefore, how to solve the above-mentioned deficiencies and inconveniences of conventional use is the direction that relevant industries in this industry want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the creators collected relevant information and, after multiple evaluations and considerations, designed the new patent holder for the locking structure of this connector combination.

The main purpose of this creation is that a plurality of conductive terminals are arranged in the socket body of the socket connector, and the base part of the metal shell is combined on the socket body, and the opposite sides of the base part are respectively provided There is a buckle part, and the bottom of the base of the plug connector is provided with a plug part that is integrated in the mating space, and a connecting part is provided at the rear side of the top surface of the base, and the base is provided with a plurality of contact terminals, The transmission unit positioned on the connection part is electrically connected to the plurality of contact terminals, and the body of the shielding shell is combined with the base, and the two opposite sides of the shielding shell are provided with push parts and push parts A groove is cut at the side, and a shaft hole is penetrated inside the groove. The two shaft holes are pivoted with a handle for turning, and the two ends of the base rod of the handle are respectively extended with side rods, and then at the ends of the two side rods When the plug connector is not locked on the socket connector, the side rods on the two sides of the handle will be supported by the surface of the two pushing parts. Relatively spread outwards, so that the second buckle end of the handle is not buckled on the second buckle part of the metal shell, and when the plug connector is coupled to the socket connector, the handle can be turned to hold the handle The pair of side rods on the two sides are located in the two grooves, so that the two side rods are elastically reset, so that the second buckle end of the handle is buckled in the second buckle portion of the metal shell, thereby connecting the socket connector and the plug The device is stabilized and locked into a whole to achieve the purpose of improving the simplicity and intuition of operation.

The secondary purpose of this creation is that during the process of unlocking and rotating the handle, the two side rods of the handle will slide along the guide surface of the second push part relative to the inner side, so that the two side rods can be smooth Unlock the rotation to achieve the purpose of improving the smoothness of operation.
