Abstract
The utility model relates to an electric connector, a terminal channel of the insulation main body is provided with a concave stage, and the conductive terminals are formed in an integral punching forming. The utility model comprises a butting part, a welding part, an interfering part arranged between the butting part and the welding part, and the interfering part is provided with a punching bulge. The conductive terminals are inserted from a welding face of the insulation main body, and the butting part firstly generates deformation; when the conductive terminals enter a wider butting face in the terminal channel, the butting part can be recovered into an original state, the punching bulge is interfered with the inner wall of the terminal channel to form a closed state for preventing welding solder from entering the terminal channel from the welding face.
Description
The relevant a kind of electric connector of the utility model, especially a kind of electric connector that is used to connect calculator central processing unit and calculator mainboard.
The prior art relevant with the utility model can be consulted the U.S. the 5th, 569, No. 045 patent, the all integrated punching moulding on strip of its conducting terminal, its butt end interconnects by one section strip reserving on it, welding ends then each self-separation is inserted in the terminal channel that insulating body is offered, thereafter the unnecessary part strip on it fractureed, thus the insertion location of finishing conducting terminal.
Though can finish the insertion of conducting terminal by this method, and can reach higher production efficiency, yet it generally can leave sharp-pointed burr in the strip place of fractureing, when the CPU pin of butt joint may scratch the surface of docking the CPU pin during start thereon.And its interference part penetrates with in its terminal channel, thereby the going deep into of mechanical arm when being unfavorable for inserting, and is difficult to operation.And the general distance of the handle part of mechanical arm interferes forced section far away when inserting, and makes the integral rigidity of conducting terminal be not enough to support the strength of inserting, and then causes the conducting terminal distortion even fracture.
The purpose of this utility model is to provide a kind of electric connector, and its conducting terminal can make things convenient for and firmly is inserted in the connector terminals passage.
For achieving the above object, the utility model electric connector includes insulating body and plurality of conductive terminals, wherein insulating body has interface and the solder side that is oppositely arranged, connect therebetween and be provided with the plurality of terminals passage, and conducting terminal forms from the strip integrated punching, comprise docking section, weld part and be arranged at the docking section and weld part between the interference part, it is characterized in that: the terminal channel inwall of insulating body convexes with boss, stamp out the butt joint projection at weld part, and on the interference part, stamp out interference protrusion.Conducting terminal inserts from the solder side of the body that insulate, its docking section because of with terminal channel in set boss interfere and produce distortion, insert its docking section shape of back and recover interference protrusion and then interfere and can firmly locate conducting terminal and form and seal more closely, and solder flux infiltrates in the terminal channel and causes the terminal performance not good can prevent to weld the time with boss.
By such scheme, the conducting terminal of the utility model electric connector can conveniently insert and can strong fix in terminal channel.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is a conducting terminal stereogram of the present utility model.
Fig. 2 is the cutaway view of the conducting terminal of the utility model electric connector part when not inserting insulating body.
Fig. 3 is that the conducting terminal of the utility model electric connector inserts local cutaway view behind the insulating body.
See also shown in Figure 2, the utility model electric connector includes insulating body 2 and plurality of conductive terminals 1, wherein insulating body 2 has interface 201 and solder side 202, offer a large amount of terminal channels 21 (only showing among the figure) in interface 201 and 202 of solders side, has a boss 22 near solder side 202 1 ends in each terminal channel 21, thereby make the upper shed 203 of interface 201 of insulating body 2 big than the under shed 204 of solder side 202, boss 22 has to the inclined-plane 221 that terminal channel 21 is offered near solder side 202 places, in order to the insertion of the docking section 11 of guiding conducting terminal 1.
See also Figure 1 and Figure 2, conducting terminal 1 comprise docking section 11, weld part 13 and be arranged at docking section 11 and weld part 13 between interference part 12, wherein docking section 11 and weld part 13 all are the direction settings of inserting insulating body 2 along conducting terminal 1, and interference part 12 then becomes special angle (being set to 90 degree in the present embodiment) with it.Docking section 11 comprises extension 111 and contact site 112, and contact site 112 is arranged at the top and from extension 111 laterally projecting two protuberances 113, Yi Bian wherein do the arc bending, with the slip of guiding CPU pin and carry out excellent electrical property with the CPU pin and contact.12 two ends, interference part offer breach 121, in order to insulation shell 2 inwall interferences, and form the strong fix of conducting terminal 1 and insulating body 2.12 longitudinally punching press has strip interference protrusion 122 along the interference part, form along the interference part interference effect of 12 longitudinally with boss 22 with insulation shell 2 inwalls, thereby the sealing that conducting terminal 1 and insulating body 2 are formed the terminal channel 21 of insulating body 2, can prevent the solder flux upstream end subchannel 21 of fusing when weld part 13 is welded in printed circuit board (PCB) (not shown), and influence the signal transmission of CPU pin (not shown) and conducting terminal 1.Stamp out welding projection 131 on the weld part 13 to strengthen the rigidity of docking section 13, prevent to produce permanent deformation when it from passing terminal channel 21 or fracture.
See also Fig. 2 and Fig. 3, conducting terminal 1 inserts from the solder side of the body 2 that insulate, the contact site 112 on its 11 tops, docking section is 221 insertions along the inclined-plane, because of a protuberance 113 is the bowing setting, and the under shed 204 of the solder side 202 that at first inserts is less relatively, therefore docking section 11 produces strains, make it enter the top wider part by external force after, again by its elastic return original state.Then, interference part 12 enters above-mentioned under shed 204, and interference protrusion 122 is interfered the location with the boss 22 in the terminal channel 21, itself and terminal channel 21 inwalls are formed to be sealed and matched, thereby the under shed 204 of blind end subchannel 21, in the solder flux upstream end subchannel 21 that prevents to melt when it is welded in printed circuit board (PCB), influence the laser propagation effect of the signal of telecommunication.At last, the reserved part strip that is connected in the weld part 11 of conducting terminal 1 is fractureed.In addition, have welding projection 131 on the weld part 13 of conducting terminal 1, the rigidity that it can strengthen weld part 13 can not produce permanent deformation when the docking section 11 of conducting terminal 1 is inserted or fractures.And the mechanical arm (not shown) of clamping conducting terminal 1 is in the outside of the solder side 202 of insulating body 2 all the time when inserting, and is convenient to operation, helps improving the rate that comes into force.
