Electric connector
The utility model relates to a kind of electric connector, is meant that especially a kind of structure is more firm, the polarization of terminal better, the better electric connector of screening effect.
In the electric connector product scope, for connector to the positioning and fixing of the fixing and conducting terminal of circuit board etc. innovative design is arranged all, TaiWan, China patent the 85202862nd, 85217217, No. 86200240 some electric connectors are disclosed, these electric connector products to the fixing of circuit board generally is to extend several pins downwards in the bottom of shielding casing, and corresponding to offering some through holes on the circuit board, also weld in the through hole with above-mentioned pin insertion circuit board and fixed, location for conducting terminal in the connector, then be that docking groove inwall in connector has some separate slots, conducting terminal is gone in these separate slots along the butt joint direction group of connector, conducting terminal is fastened in the aforesaid separate slot by hangnail set on the terminal.Yet, the fixing pin that extends owing to the bottom of adopting shielding casing of existing electric connector fixes on circuit board, so the bottom of connector shielding housing can not be covered by fully that it is inner butted part, and causes the effect that prevents electromagnetic interference of connector bad.And the conducting terminal of existing connector is gone in the docking recess along the butt joint direction group of connector, when connector docked with butt connector, under the effect to relay, conducting terminal produced displacement along the butt joint direction easily in separate slot, and influence butt joint effect, even breaking phenomena takes place.
Main purpose of the present utility model is to provide a kind of structure firm, the better electric connector of conducting terminal locating effect.
The purpose of this utility model is achieved through the following technical solutions: the utility model mainly includes shielding casing, insulating body and plurality of conductive terminals, wherein shielding casing includes upper surface, the two opposite sides edge of this upper surface extends to form two routine faces again downwards, and engage by the extension of described both side surface and form lower surface with respect to upper surface, form a butt joint space by described upper surface, two sides and lower surface, for the butt joint of butt connector, the extension of aforementioned two sides extends a pair of at least fastening member again respectively downwards in joint; Insulating body includes a substrate, this substrate is located at the rear side in aforementioned butt joint space perpendicular to the butt joint direction, its side towards the butt joint direction is provided with some first accepting grooves, appropriate location on this side is extended at least one location-plate again, is provided with several second accepting grooves again in the edge of described location-plate butt joint direction; Conducting terminal has contact site and interference part, and wherein the interference part is positioned in first location notch of aforesaid base plate, the bearing of trend of this interference part and electric connector to dock direction perpendicular.
Compare prior art, the utlity model has following advantage: the orientation of conducting terminal of the present utility model and electric connector to dock direction perpendicular, and make the locating effect of terminal better, and the junction surface of shielding casing extend some to fastening member, by making structure of the present utility model more firm to the fixing of these fastening members.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is another angle three-dimensional exploded view of the present utility model.
Fig. 3 is a part assembling three-dimensional exploded view of the present utility model.
Fig. 4 is stereoscopic figure of the present utility model.
Fig. 5 is another angle stereoscopic figure of the present utility model.
The utility model will be further described below in conjunction with drawings and Examples:
See also Fig. 1, the utility model electric connector mainly comprises: shielding casing 1, be housed in the insulating body 2 in the shielding casing 1 and be positioned at plurality of conductive terminals 3 on the insulating body 2.
See also Fig. 1 and Fig. 2, wherein shielding casing 1 is that integrated punching is again through bending forming, which is provided with a upper surface 10, and some first elastic buckle pieces 100 are arranged in these upper surface 10 upper punches, each extends two sides 11 downwards in the relative both side edges of described upper surface 10, the lower edge of these two sides 11 extends final the joint and forms a lower surface 12 to close mutually direction respectively again, in lower surface 12 upper punches several second elastic buckle pieces 120 are arranged, and in the edge at junction surface each extends to form two fastening members 121 downwards, this two fastening member 121 is the finger-like shell fragment that interlaces before and after two positions, by them shielding casing 1 is locked on the circuit board (not shown), by the trailing edge of above-mentioned upper surface to extend to form a rear surface 13 away from direction, the both side edges place of this rear surface 13 is again to extend to form two pins 130 away from direction, offer some snapping slotted eyes 15 in upper surface 10 and 13 junctions, rear surface, it can be used for snapping insulation shell 2 (being detailed later).
Insulation shell 2 is one-body molded, comprise a substrate 20, which is provided with a front surface 200, offer some "T"-shaped first accepting grooves 201 thereon, again on the top of first accepting groove 201 to extend a location-plate 21 away from direction, downside in this location-plate is provided with and first accepting groove, 201 the same number of second accepting grooves 210, treat that these second accepting grooves 210 just can connect with first accepting groove 201, end in second accepting groove 210 promptly has some through holes 211 near location-plate 21 edges, it can be used for positioning and fixing conducting terminal 3 (being detailed later), has respectively extended upward several projections 202 at the upper limb place of front surface.
Conducting terminal 3 has contact site 30, its ora terminalis bending certain angle also is housed in the through hole 211 of aforementioned location-plate 21, extend to form first interference part 31 by this end, it can be housed in second set on the described location-plate 21 accepting groove 210 (consulting Fig. 3), second interference part 32 that can be contained in first accepting groove 201 is continued to extend to form through bending 90 degree in first interference part 31, and the formation weld part 32 that also narrows down is gradually continued to extend in this second interference part 32.
See also Fig. 4 and Fig. 5, when the utility model is combined integrated, earlier second interference part 32 of conducting terminal 3 is gone in first accepting groove 201 of insulating body 2 to the rightabout group that weld part 33 extends along it, and first interference part 31 is housed in second accepting groove 210 on the location-plate 21, simultaneously, one of contact site of conducting terminal 3 is held in the through hole 211 that is inserted on the location-plate 21, so, terminal 3 firmly be positioned at insulating body 2 on, then, insulating body 2 is gone into by the rear side group of shielding casing 1, make several set on the substrate 20 projections 202 buckle into the upper surface 10 of shielding casing 1 and rear surface 13 between in the set snapping slotted eye 15, again will 13 bendings downwards in rear surface, back, make its be close proximity to insulation shell 2 on, like this, shielding casing 1 also firmly is combined into one in insulation shell 2 intactly is coated on.
