Figure 1 shows that existing sim card connector, electronic card coupler 10a includes an insulating base frame 11a and most contact terminal 12a form, this insulating base frame 11a is provided with two rows and the most individual terminal storage tank 13a of every row, described two row's terminal storage tank 13a are positioned at relative both sides, wherein insulating base frame 11a is formed with the retaining wall 15a of protrusion at its three side, be provided with depressed part 14a at the join close medium position in zone of described retaining wall 15a and insulating base frame 11a, to realize saving the purpose of material, yet because the existence of depressed part 14a makes insulating base frame 11a can be distributed in the weak position of retaining wall 15a at the joint line of the process medium fluid of moulding, so that insulating body is easy to generate slight crack in material joint line position and ruptures in the terminal group process of assembling, influences the useful life of connector.

Therefore, a kind ofly not only can realize saving the purpose of material but also can guarantee that the normal sim card connector that uses of electronic card coupler just becomes a kind of demand.

[utility model content]

The purpose of this utility model is to provide a kind of insulating body of connector that prevents to produce the electronic card coupler of slight crack.

For achieving the above object, the utility model adopts following technical scheme: a kind of electronic card coupler, it comprises insulating body, somely is housed in the conducting terminal in the insulating body and is mounted on retaining sheet on the insulating body.Described insulating body comprises a base portion and is formed at the retaining edge of insulating body base portion three sides, described base portion is provided with the plurality of terminals of planting for conducting terminal and accommodates conduit, described terminal accommodating conduit divides two rows to be arranged at relative both sides, aforementioned retaining sheet assembling back forms the receiving space that the power supply subcard is planted jointly with insulating body, insulating body offers a depressed part at its base portion and the crossing zone of retaining edge simultaneously, offer the wall that groove makes that formation approaches between depressed part and groove in a side near described depressed part, the joint line of material is formed on bigger zone of insulating body intensity or the close bigger zone of intensity when making the insulating body moulding by described groove is set, thereby prevent that insulating body from producing slight crack or rupture in the connector assembling process, guarantee the normal use of electronic card coupler.

Compared to prior art, the utility model electronic card coupler has following beneficial effect: by be provided for controlling the groove of Flow of Goods and Materials speed on insulating body, the material joint line is formed in the bigger zone of insulating body intensity when making the insulating body moulding of connector, thereby prevents that insulating body from producing slight crack or fracture taking place and the influence use in the connector assembling process.

[embodiment]

See also shown in Figure 2ly, the utility model electronic card coupler 1 includes insulating body 10, plurality of conductive terminals 20 and a pair of retaining sheet 30 that is installed on insulating body 10 both sides.

Please continue to consult Fig. 2 to shown in Figure 4, insulating body 10 roughly is flat tabular with the plastic material moulding, it comprises that being provided with some first of conducting terminals of accommodating accommodates that conduit 13 and second is accommodated the base portion of conduit 14 (not label) and the retaining edge 11 of the protrusion that forms respectively from three sides of described insulating body base portion, 12 and 17, first accommodates conduit 13 and second accommodates the both sides that conduit 14 symmetries are positioned at base portion, dig respectively with the position at the close middle part of base portion intersecting area at retaining edge 11 and 12 and to be provided with

depressed part

15 and 16, keep off edge 11 is provided with location retaining sheet 30 in the corresponding position that forms depressed part 15 slit 110 simultaneously, identical therewith retaining edge 12 is provided with slit 120 to locate another retaining sheet 30 in the corresponding position that forms depressed part 16, described base portion is provided with and prevents that insulating body 10 from the recess 19 of warping phenomenon taking place when moulding simultaneously, be provided with the wall (not label) that groove 18 makes that formation approaches between depressed part 15 and the groove in a side near depressed part 15, the flowing velocity of material during with control insulating body 10 moulding by groove 18, make the final joint line of material move to the bigger zone of insulating body intensity or, avoid causing the phenomenon that insulating body produces slight crack or takes place to rupture in the assembling process of connector in the zone of weakness because of joint line is formed at the insulating body weakness zone near the bigger zone of intensity by insulating body 10.

Each conducting terminal of plurality of conductive terminals 20 all has the weld part 25 of reaching the electrical contact site that contacts 22 with electronic cards and being welded in circuit board, wherein contact site 22 has certain radian and its head is provided with the holding section 21 that parallels with weld part 25, weld part 25 is to be extended to form by fixed part 24 bending downwards, wherein fixed part 24 both sides are provided with the inlay (not label) of protrusion, and kink 23 links to each other with contact site 22 and fixed part 24 respectively.Conducting terminal 20 is assembled in after the terminal accommodating conduit of correspondence, holding section 21 is positioned by the slot 130 and 140 of the correspondence of terminal conduit, make and to have good coplane degree via accommodating the contact site 22 that conduit stretches out the insulating body base portion, guarantee to contact with the electronic cards excellent electrical property of inserting, fixed part 24 is contained in the support that is subjected to the conduit inner platform behind the conduit, and the inlay of its both sides embeds and conducting terminal cooperated with insulating body stablize simultaneously.
