[background technology]

United States Patent (USP) announces the 5th, 915, the electric connector that has disclosed a kind of in order to connecting circuit plate and butt connector No. 976, it comprises insulating body, be inserted in the terminal on the insulating body and be covered in shielding casing on the insulating body sidewall, the edge of described shielding casing is provided with adjutage, these adjutages are approximately perpendicular to the edge bending of shielding casing and extend, the accepting groove of the corresponding earth terminal of the sidewall of insulating body is provided with groove, thereby adjutage sees through groove and the earth terminal electric connection makes shielding casing ground connection.Because the sidewall thickness of insulating body is less, thereby adjutage can only be provided with less length and just can be placed in the groove.Adjutage bending back and earth terminal Elastic Contact, because length is less, the elasticity deficiency of adjutage, appearance causes with termination contact bad.

Therefore, be necessary to design a kind of electric connector that overcomes above-mentioned defective.

[utility model content]

Technical problem to be solved in the utility model is: a kind of electric connector is provided, and its shielding casing well contacts with earth terminal.

For addressing the above problem, the utility model adopts following technical scheme: a kind of electric connector, and it comprises insulating body, terminal and shielding casing, described insulating body comprises the two side of lengthwise, be provided with receiving space between the two side, sidewall is provided with the terminal containing slot that is communicated with receiving space; Described terminal comprises earth terminal, and described terminal is installed in the terminal containing slot, and each terminal comprises contact site, holding parts and afterbody; Described shielding casing is covered on the sidewall of insulating body, its be provided with that main part and autonomous body extend and can with the contacted grounding arm of earth terminal; Described grounding arm comprises first arm that is covered in sidewall surfaces and second arm that extends from the bending of first arm, forms a slit between first arm and main part, and second arm contacts with earth terminal.

Compared with prior art, the utility model electric connector has following beneficial effect: the grounding arm of the shielding casing of the utility model electric connector has first arm that is covered on the insulating body sidewall, be provided with slit between the main part of first arm and shielding casing, first arm can springing on perpendicular to the direction of sidewall wall, thereby for second arm provides enough elasticity grounding arm is well contacted with earth terminal.

[embodiment]

See also Figure 1 and Figure 2, the utility model electric connector comprises insulating body 1, be installed on the plurality of terminals 2 in the insulating body 1 and be covered in two shielding casings 3 on the insulating body 1.

See also Fig. 2 and shown in Figure 3, described insulating body 1 comprises the two side 11 of lengthwise and connects the end walls 12 of two side 11, form receiving space 10 between the two side 11, this receiving space 10 is in order to accommodate the docking section of butt connector (not shown), and the bottom of receiving space 10 is between two side 11 and connects the base portion 15 of two side 11.The inboard of two side 11 is equipped with the terminal containing slot 13 that is communicated with receiving space 10.The top edge of each sidewall 11 is provided with some groups of fixing pieces 111, is provided with chute 112 between each group fixing piece 111.The lower edge portion of each sidewall 11 is provided with some projections 113.

See also Fig. 2 and shown in Figure 3, described plurality of terminals 2 comprises signal terminal and earth terminal, two kinds of terminal structures communicate, include contact site 21, holding parts 22 and afterbody 23, these terminals are installed in the terminal containing slot 13 of insulating body 1 respectively, and it is outer in order to weld with circuit board that described terminal tails 23 is extended insulating body.The terminal containing slot 13 of corresponding each ccontaining earth terminal, the sidewall 11 of insulating body is provided with the recess 14 that is communicated with terminal containing slot 13.

Shielding casing 3 is covered on the sidewall 11 of insulating body 1, projection 113 on these shielding casing 3 corresponding sidewalls 11 is provided with some grooves 31, the top edge of shielding casing 3 is provided with some retaining sheets 32 that can be contained in the chute 112, the lower limb of shielding casing 3 is provided with the quantity grounding arm 33 identical with the quantity of recess 14, each grounding arm 33 comprises that second arm 332 contacts earth terminal perpendicular to first arm 331 with convenient second arm in the present embodiment from first arm 331 of shielding casing 3 extensions and second arm 332 that extends from the bending of first arm.For convenient narration, shielding casing 3 parts beyond the grounding arm 33 are called main part.Be provided with slit 333 (ginseng Fig. 4) between first arm 331 and shielding casing 3 main parts, the free end of second arm 332 is provided with protuberance 334.During assembling, groove 31 ccontaining projections 113, retaining sheet 32 upwards slides from chute 112 belows, until groove 31 and projection 113, retaining sheet 32 closely cooperates with chute 112, second arm 332 of grounding arm 33 is placed in the recess 14, first arm 331 is covered on the sidewall 11 of insulating body, terminal 2 upwards is assembled in the insulating body 1 from the below, thereby second arm 332 of grounding arm 33 is connected on the holding parts 22 of earth terminal and the earth terminal Elastic Contact, because holding parts 22 is fastened in the terminal containing slot 13, second arm 332 is connected to holding parts 22, can better keep the normotopia degree of terminal.
