Description

Small volume electrical connector assembly and its plug and socket

technical field

The invention relates to the field of electrical connectors, in particular to a small-volume electrical connector assembly and its plug and socket.

Background technique

In the current high-density electrical connectors, most of them use a plug to match a socket. When users require that the plug and socket can be plugged in modularly, each plug can be locked with the socket or removed from the socket. , the usage requirements cannot be met. The reason is mainly because the locking mechanism in high-density small electrical connectors is too large compared to the connector, especially in products with small cores. If the current locking mechanism (each plug and The sockets are locked with threads or bayonet sockets), when a socket is equipped with multiple small-core plugs and each plug can be removed and locked, the overall electrical connector assembly will appear extremely bloated, and it is difficult to meet small If a relatively small barb structure is adopted, it will make it difficult for the electrical connector assembly to meet the vibration and impact requirements.

In summary, designing a small-volume electrical connector assembly with a simple structure and reliable locking has become a problem that has to be considered in the industry, because once such a product appears, it will be directly used for The volume reduction, structure simplification and connection reliability of the high-density electrical connector assembly have beneficial effects that cannot be ignored.

The inner side of the pressure plate has a stopper for press-fitting with the mating plug after mating the mating plug and the socket.

The inner side of the pressure plate is provided with a positioning groove for positioning the adapter plug, and the opening is located on the bottom of the positioning groove.

The socket on the pressing plate is in the shape of a strip.

Because the small-volume electrical connector assembly is detachably and fixedly equipped with a pressure plate at the front end of the socket housing, the pressure plate is provided with a socket for plug insertion, and the socket has a function for inserting the corresponding plug into the socket and rotating to set the angle. The plug-in structure is mated with the plug. The plug shell is provided with a back-off part for press-fitting with the inner side of the pressure plate after the plug and the socket are mated. When using the electrical connector assembly, only the plug needs to be inserted into the corresponding The socket, rotate and make it plugged with the socket, fix the pressure plate on the socket shell, then the plug will also be pressed on the socket at the same time and keep plugged in with it. When the plug needs to be separated from the socket, it only needs to be loosened Press the plate, then unplug the plug from the socket and then rotate it to set the angle so that it can withdraw from the press plate. In the same way, when there are more than two plugs, when it is necessary to unplug one or several plugs, just Loosen the pressure plate and select the plug to be pulled out. Since most of the locking structure of the small-volume electrical connector assembly is integrated on the plug and the socket, the only peripheral locking part (pressing plate) can also lock multiple plugs at the same time, so it is small in size and stable in structure. Simple, at the same time, since the locking between the plug and the socket is "pressed" by the pressure plate, the strength is very easy to guarantee, and it can easily meet the requirements of anti-vibration and anti-loosening. It can be seen that this small-sized electrical connector The components are not only small in size and simple in structure, but also have the characteristics of reliable locking.

Furthermore, on the one hand, the positioning groove can play the role of positioning the plug to ensure that it can be smoothly plugged into the corresponding socket of the socket, and on the other hand, it can also play the role of preventing rotation, preventing it from colliding with the socket during use. Torque is generated between the socket parts; the requirements for the shape of the plug can be relaxed after the socket is made into a strip shape; after the rear end of the plug shell is used as the socket part, the plug can be completely submerged in the pressure plate when the plug and the socket are mated In the middle, the two are integrated, on the one hand, it beautifies the appearance effect, on the other hand, it also plays a role in protecting the plug.
