Description

Electric connector

[technical field]

The utility model is relevant a kind of electric connector, refers to a kind of electric connector that is installed on the circuit board especially.

[background technology]

Electric connector is widely used in electronic applications, for example can transfer the mobile phone or the USB on other equipment (Universal Serial Bus is called for short USB) of data information and use electric connector, is fixed on the circuit board, to form the path of signal transmission.

A kind of electric connector can be mounted on the circuit board, and it comprises insulating body, is contained in the plurality of conductive terminals in the insulating body, and the shielding casing that is coated on insulating body.Described insulating body comprises a base portion and the hyoplastron portion of extending forward from the place, centre position of base portion; Described shielding casing is enclosed by some walls portion and forms and form hyoplastron portion and be convexly equipped with wherein receiving space, and receiving space is used for holding insertion butt joint electric connector wherein.The port of receiving space is butt joint electric connector insertion mating interface wherein.The wall portion that is positioned at the receiving space top offers the pair of catches groove, and butt joint electric connector correspondence is provided with pair of catches portion, and in butt joint electric connector insertion receiving space, its latch part is immobilizated in the lock buckling groove, avoids docking electric connector and rocks in receiving space.

For large scale electronic equipments such as computers, dress electric connector size thereon is bigger, and the mating interface place of shielding casing generally is provided with the guidance part of toroidal, and guiding exceeds the latch part of the butt joint electric connector of receiving space height and inserts receiving space.Yet nowadays, this kind electric connector also is used for portable electric appts more and more, for example: mobile phone, camera, digital audio-video equipment etc.; The electric connector and other electronic component dimensions that are used for the said equipment all develop towards microminiaturized direction; It is irrealizable at the butt joint spigot of electric connector the toroidal guidance part being set.

If the setting of cancellation guidance part, the not only insertion of inconvenient butt connector, and the bottom of docking the latch part of electric connector might exceed the wall portion of receiving space top, so, cause the bottom of latch part to be inserted to the electric connector outside in the butt connector insertion process probably, make the latch part distortion.

At the common way of the problems referred to above industry is the insertion of knocking guiding butt joint electric connector in angle at shielding casing mating interface place down, yet, be subjected to the restriction of material hardness, knock the angle down then the thickness of chamfering is limited mating interface part is whole, foregoing problems still takes place easily.

In sum, necessary existing electric connector is improved, to overcome aforementioned disadvantages of the prior art.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector, and it can provide good guide function to the butt joint electric connector ensureing that electric connector is beneficial under the prerequisite of miniaturization development.

For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, can be connected with banjo, it comprises insulating body, be loaded on the plurality of conductive terminals in the insulating body and be coated on the insulating body and form the mating interface that banjo inserts and the shielding casing in plant space are provided, described shielding casing is provided with lock buckling groove, wherein offers chamfering with the corresponding position of lock buckling groove to the plant direction in space on mating interface.

Compared with prior art, the utility model electric connector knocks angle guiding banjo down and inserts in the plant space in the position of corresponding lock buckling groove on the shielding casing mating interface, the height of chamfering can be guaranteed, and enough the importing banjo inserts and can be because of not inserting the serviceability of improper damage banjo smoothly; Be adapted at using on the small-sized electronic equipment.
