Description

Electric connector

[technical field]

The relevant a kind of electric connector of the utility model relates in particular to a kind of electric connector that can be connected with circuit board.

[background technology]

See also a kind of data storage device that the China's Mainland utility model of on April 5th, 2006 bulletin is disclosed for CN2770276Y number with the utility model related art, this data storage device includes insulating body, be located at the conducting terminal on the insulating body and be assembled to metal shell on the insulating body, when this storage device electrically connects mutually with butt connector, to there be electrostatic charge to be dispersed on the metal shell and can't discharges, cause the shield effectiveness of metal shell not good, transmission signal will be subjected to electromagnetic interference and make the storage device can't operate as normal.

Therefore, at above-mentioned technical problem, be necessary to provide a kind of structure improved electric connector that has, to overcome above-mentioned defective.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector with good shielding.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of electric connector, it includes insulating body, is assembled to metal shell and terminal group on the insulating body, wherein insulating body is provided with the plurality of terminals passage, terminal group is located on the terminal channel of insulating body, terminal group includes an earth terminal, and electric connector also includes shell fragment, and metal shell electrically connects by shell fragment mutually with earth terminal.

Compared with prior art, the utlity model has following beneficial effect: connect metal shell and earth terminal by shell fragment, make metal shell can reach the effect of ground connection, thus can be so that the electrostatic charge on the metal shell obtains discharging.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

[embodiment]

See also Fig. 2 and shown in Figure 5, the utility model electric connector 100 includes insulating body 1, terminal group 2, metal shell 3 and shell fragment 4.

See also Fig. 1 to shown in Figure 5, insulating body 1 is step-like structure, its rear end is higher than front end, insulating body 1 is provided with plurality of terminals passage 12, the holding slot 14 that is provided with an accepting groove 13 that is connected with terminal channel 12 and is connected with accepting groove 13 in terminal channel 12 tops of insulating body 1 is provided with the cylindrical projection 15 that protrudes out downwards in the rear end lower of insulating body 1.

Terminal group 2 includes docking section 21, can be soldered to the weld part 23 of circuit board and the connecting portion 22 that connects docking section 21 and weld part 23, be provided with upwards and interference part 225 in connecting portion 22 to the both sides projection, wherein, this terminal group 2 comprises that one has the earth terminal 20 of ground connection effect.

Second contact site 42 that shell fragment 4 includes first contact site 41, holding parts 43 and connects first contact site 41 and holding parts 43 is provided with projection 432 in holding parts 43.

See also shown in Figure 5ly,, only represent with simple schematic form at this because metal shell 3 is not key character of the present utility model.

See also Fig. 1 to shown in Figure 5, during assembling, terminal group 2 is assembled on the terminal channel 12 on the insulating body 1, the docking section 21 of terminal group 2 is positioned at the front end of insulating body 1, weld part 23 extends the rear end of insulating body 1, and the interference part 225 on the connecting portion 22 can make conducting terminal 2 be fixed on better in the terminal channel 12 of insulating body 1 with insulating body 1 interference.Shell fragment 4 is assembled on the insulating body 1, the holding parts 43 of shell fragment 4 is retained in the holding slot 14 of insulating body 1, first contact site 41 and second contact site 42 are housed in the accepting groove 13 of insulating body 1, at this moment, first contact site, the 41 convex upper surfaces that stretch out insulating body 1, second contact site 42 does not contact with earth terminal 20.At last, metal shell 3 is coated on the insulating body 1, metal shell 3 moves down first contact site 41 of shell fragment 4 by pressure in accepting groove 13, and drives second contact site 42 and move down with the connecting portion 22 of earth terminal 20 and contact.Thereby make metal shell 3 can reach the effect of ground connection by shell fragment 4 connection metal shells 3 and earth terminal 20.

In other embodiment of the present utility model, shell fragment 4 also can be shaped on the metal shell 3, and shell fragment 4 extends in the insulating body 1 and with earth terminal 20 and contacts simultaneously, can make metal shell 3 reach the effect of ground connection equally.
