US Patent No. 6,129,587 discloses a receptacle connector assembly 6 , as shown in FIG. 6 , which is a perspective view of the first embodiment of the receptacle connector assembly 6 , which has a conductive shielding shell 61 , an insulating body 62 and a plurality of terminals 63 . The shielding shell 61 is a plate-shaped configuration made of metal material, and the insulating body 62 is integrally formed directly with the shielding shell 61, so that the side edges of the shielding shell 61 are embedded in several vertical walls 621, 622, 623, a receiving space 64 is formed between the vertical walls 621, 622, 623 and the bottom wall 625 of the insulating body 62, and a buckling portion 624 is provided at the top of each vertical wall 621, 622, 623 of the insulating body 62. The buckling part 624 can buckle the buckling arm of the mating plug connector, because the plane part 611 of the shielding shell 61 is flush with the top surface A1 of the insulating body 62, thereby reducing the overall height of the electrical connector, but due to the buckling part 624 is located on the body, and its thickness must meet its strength requirements, so it takes up a lot of space, which makes the design have some shortcomings, that is, the height of the socket connector cannot be reduced to the minimum, and it cannot adapt to the miniaturization of notebook computers. requirements. US Patent No. 5,702,271 discloses another conventional low profile receptacle connector, which still has the defects of the above-mentioned prior art, that is, a large space is occupied because the latching portion is disposed on the body.

【Content of invention】

The purpose of the utility model is to provide a socket connector, which can effectively reduce the height of the connector while ensuring the signal transmission quality.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the socket connector includes an insulating body, a terminal module and a shielding shell, wherein a receiving space for the insertion of a docking plug connector is provided on the front surface of the insulating body, and it is connected with the front surface. On the side adjacent to and connected to the surface, there is a gap that communicates with the receiving space to accommodate the buckle arm of the plug connector. The terminal module is stored in the above-mentioned receiving space, and the shielding shell is covered on the surface of the insulating body. A position on the shielding shell corresponding to both sides of the notch of the insulating body is provided with a limit device that can cooperate with the buckle arm of the plug connector, and is used to fix the mating plug connector in the receptacle connector. When the mated plug connector is inserted into the receptacle connector, the limit device can effectively buckle the buckle surface of the buckle arm of the mated plug connector, so that the insulating body does not need to be provided with a buckling part, and the mated plug can be connected. The socket connector is fixed in the socket. Compared with the existing RJ series connector, the overall size of the socket connector can be significantly reduced.

Compared with the prior art, the utility model is provided with a limiting device on the shielding shell, and the limiting device is just able to effectively buckle the buckling surface of the buckling arm of the docking plug connector, so that the insulating body does not need to be provided with a top , its height can be significantly reduced, so that the entire electrical connector occupies a small space, which is conducive to the development of short and thin electronic components.
