Description

Socket connector

[technical field]

The utility model relates to a kind of socket connector, refers in particular to a kind of low configuration modularization communication network socket connector (Modular Jack).

[background technology]

The socket connector (Modular Jack) that is used for communication network, it can engage with the pin connector of butt joint and be used for transmission signals.United States Patent (USP) 6,129,587 disclose a kind of socket connector combination 6, as shown in Figure 6, are the stereograms that above-mentioned socket connector makes up 6 first embodiment, and it has conductive shield shell 61, insulating body 62 and plurality of terminals 63.Shielding case 61 is tabular configurations made from metal material, insulating body 62 is directly to be made of one piece with shielding case 61, so that the lateral edges of shielding case 61 is embedded in the plurality of vertical wall 621 of insulating body, 622, in 623, the vertical wall 621 of insulating body, 622,623 and diapire 625 between be formed with a receiving space 64, insulating body 62 each vertical wall 621,622,623 top is equipped with a holding part 624, this holding part 624 can be detained the button gripping arm of holding the banjo connector, because the planar portions 611 of shielding case 61 is mutually concordant with the end face A1 of insulating body 62, thereby reduce the whole height of electric connector, but because holding part 624 is provided in a side of on the body, its thickness must satisfy its requirement of strength, so it takies bigger space, and make this design also not enough to some extent, it is minimum to be that the height of socket connector can't be reduced to, and can't adapt to the requirement of notebook computer miniaturization development.United States Patent (USP) the 5th, 702 has disclosed another kind of existing low configuration socket connector No. 271, and still there is the defective of above-mentioned indication prior art in it, promptly can take bigger space because holding part is provided in a side of on the body.

[summary of the invention]

The utility model purpose is to provide a kind of socket connector, is guaranteeing can to effectively reduce the connector height under the situation of signal transmission quality.

For achieving the above object, the utility model adopts following technical scheme: socket connector comprises insulating body, terminal module and shielding casing, wherein offering on the front surface of insulating body can be for the receiving space of banjo connector insertion, an and side that join adjacent with front surface is provided with the breach that is connected with described receiving space with the button arm that holds pin connector, the terminal module is housed in the above-mentioned receiving space, shielding casing is coated on the surface of insulating body, position corresponding to the breach both sides of described insulating body on the shielding casing is provided with a stopping means that can match with the button arm of pin connector, is used for the banjo connector is fixed in the socket connector.When the pin connector of butt joint is inserted in the socket connector, stopping means just can effectively be detained the buckle face of the button arm of holding the banjo connector, make insulating body need not to be provided with holding part, just the pin connector of butt joint can be fixed in the socket, this socket connector is compared with existing RJ series connector, and its overall dimensions can have tangible reduction.

Compared to prior art, the utility model is by being provided with a stopping means on shielding casing, this stopping means just can effectively be detained the buckle face of the button gripping arm of holding the banjo connector, make insulating body need not to be provided with the top, it highly can obviously reduce, it is little to make that whole electric connector takes up room, thereby helps the development of the short and small thin typeization of electronic building brick.
