Abstract

The utility model discloses an electric connector installed on circuit plate. The electric connector comprises an insulation body provided with a plurality of terminal and a covering shell coated at the peripheral of the insulation body. The bottom surface closing to the circuit plate on the insulation body is provided with two dovetail grooves. The groove comprises an opening end opened on the connecting surface of the insulation body and accommodation part at the bottom surface. The angle between the extending direction at both sides wall of the accommodation part and the connecting surface is acute angle to supply the effect of fixing and locating. A pair of dovetail fixing tablets is formed on the groove of the insulation body related to the covering shell. The slide of the covering shell from the insulation body is avoided by using the match between the groove and the fixing tablet.

Description

Electric connector

The utility model is about a kind of electric connector, refers to the electric connector that a kind of shielding casing and insulating body can firmly combine especially.

The prior art relevant with this case sees also United States Patent (USP) the 5th, 378, No. 172 content.Existing electric connector product offers a pair of rectangular recess on the diapire of its insulating body, accommodate rectangular sheet on the shielding casing with correspondence, thereby prevent that shielding casing from getting loose from the body that insulate.Yet this type of rectangular configuration only can prevent that shielding casing breaks away from insulating body along the direction perpendicular to circuit board, and can't stop shielding casing to break away from from insulating body along the butt joint direction.Therefore, this kind electric connector can not guarantee preferable anti-stop signal effects of jamming.

Therefore, need a kind of electric connector of improvement, all can keep firm the combination in any direction with insulating body with the shielding casing of guaranteeing electric connector.

Main purpose of the present utility model is to provide a kind of electric connector of improvement, and this electric connector has dovetail shaped retaining sheet and the groove that pair of matched is closed, thereby the shielding casing of guaranteeing electric connector is gone up all with insulating body can keep firm the combination in any direction.

According to above-mentioned purpose, electric connector of the present utility model comprises insulating body, plurality of conductive terminals and shielding casing.Insulating body has some sides, in wherein offering at least one groove at least one side, this groove comprises openend that is positioned on the adjacent side and the accommodation section that is connected with this openend, and this accommodation section has at least one sidewall, and the angle between the bearing of trend of this sidewall and side, aforementioned openend place is less than 90 degree.Plurality of conductive terminals is installed on the insulating body, comprises being used for reaching outside the outstanding insulating body to be soldered to the abutting end of circuit board with the contacted butt end of butt connector.Shielding casing is coated on outside the insulating body, shape of corresponding described groove is provided with retaining sheet on it, this retaining sheet is to be placed in the accommodation section of this groove, and the openend by this groove links to each other with shielding casing, is positioned on the insulating body thereby by cooperating of this retaining sheet and groove shielding casing held.

Because adopt such scheme, the utility model can firmly combine insulating body and shielding casing, thereby make the unlikely slippage on the body that insulate of shielding casing, with the function of guaranteeing that preferable anti-signal disturbs.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the three-dimensional exploded view of the utility model electric connector.

Fig. 2 is the three-dimensional combination figure of the utility model electric connector.

Fig. 3 is the upward view of the utility model electric connector.

Please merge and consult Fig. 1, Fig. 2 and Fig. 3, electric connector 100 of the present utility model is depositing plate type modularized socket connectors that are installed on the circuit board, the shielding casing 1 that this electric connector 100 comprises insulating body 2, is contained in the plurality of conductive terminals 3 of this insulating body 2 and is coated on insulating body 2 outsides.

Insulating body 2 is provided with a receiving space 26 holding plurality of conductive terminals 3, this conducting terminal 3 can with dock connector terminals (figure does not show) and reach electric connection.This insulating body 2 has six sides, and wherein front end is an interface 24, and is bottom surface 23 towards a side of circuit board on the insulating body 2.Offer a pair of dovetail shaped groove 20 on this bottom surface 23, this groove 20 comprises openend 21 that is opened on insulating body 2 interfaces 24 and the accommodation section 27 that is positioned at bottom surface 23.Interface 24 with respect to insulating body 2 on this accommodation section 27 oppositely is extended with an abutment walls 25, interface 24 angles in an acute angle of this abutment walls 25 and insulating body 2.Opposite side away from openend 21 on the groove 20 is the afterbody 22 of groove 20, and the width of this afterbody 22 is greater than the width of this openend 21, thereby the angle that makes 24 of the bearing of trend of these groove 20 two sides 28 and aforementioned openend 21 place interfaces is less than 90 degree.

The shielding casing 1 of this electric connector 100 is to be formed by the punching out of a sheet metal one, is formed with the interface 24 of an antetheca 14 with corresponding coated insulation body 2 on it.Bottom margin from this antetheca 14 is extended with a pair of dovetail shaped retaining sheet 10 respectively towards the direction away from this antetheca 14, and this retaining sheet 10 can corresponding be contained in the groove 20 of insulating body 2.One end of retaining sheet 10 is formed with a free end 13, and this free end 13 is wider than the leading edge 12 of this retaining sheet 10.

The conducting terminal 3 of this electric connector 100 comprises the elasticity docking section 31 that is placed in insulating body 2 receiving spaces 26, and stretch out insulating body 2 with related circuit plate (figure do not show) junction surface 32 of welding mutually.

During assembling, earlier conducting terminal 3 is mounted in the insulating body 2, again shielding casing 1 is covered in insulating body 2 outer surfaces.Retaining sheet 10 on the shielding casing 1 is contained in respectively in the corresponding recesses 20 of insulating body 2, and is resisted against on the abutment walls 25 of groove 20, and the free end 13 of retaining sheet 10 supports the afterbody 22 that terminates in groove 20.Because the free end 13 of this retaining sheet 10 is wider than the openend 21 of groove 20, simultaneously, the abutment walls 25 of groove 20 is towards groove 20 afterbodys 22 diagonally extendings, and borrow aforementioned lateral wall 28 fixings to locate, thereby this retaining sheet 10 can not break away from corresponding grooves 20, thereby shielding casing 1 and insulating body 2 are more firmly combined.
