Execution mode

Following conjunction with figs. further specifies each specific embodiment of the present utility model and step thereof:

Shown in Fig. 1～2, it illustrates a preferred embodiment of the present utility model.Electric connector 10 of the present utility model comprises insulating body 2 and conducting terminal 12.Wherein, insulating body 2 has a plurality of holes 4, a groove 6 and a slotted eye 8 at least.Above-mentioned hole 4 is communicated with slotted eye 8 respectively, that is hole was located on the base plate of insulating body 2 in 4 minutes, and base plate and four sidewalls then form slotted eye 8.Hole 4 more comprises one first group of hole 42 and one second group of hole 46.First group of hole 42 and second group of hole 46 lay respectively at the both sides of groove 6.Be that in preferred embodiment, groove 6 crosscuts are through insulating body 2, and groove 6 dark and slotted eyes 8 what this need emphasize.Therefore, 12 (being the conducting terminal 12 of groove 6 both sides) crosscuts of the positive and negative conducting terminal of present embodiment run through a groove 6, and the probability that makes electric connector 10 may produce arc spark lowers.

And complex root conducting terminal 12 is inserted in the above-mentioned hole 4.Above-mentioned conducting terminal 12 comprises first row's terminal 122 and second row's terminal 124.Wherein, an end of first row's terminal 122 and second row's terminal 124 extends in the slotted eye 8, and the other end then extends to outside the insulating body 2.In preferred embodiment, extend to insulating body 2 outer first row's terminal 122 and second row's terminals 124 and all be bent with a plurality of kinks 16.As shown in Figure 2, first row's terminal 122 and second row's terminal 124 be preferable to have two place's kinks 16 respectively, wherein Mo Duan kink 16 respectively with the parallel sidewalls of insulating body 2.And second row's terminal, 124 length are longer than first row's terminal 122.Yet above-mentioned conducting terminal 12 bendings and the parallel main purpose of terminal ends are to electrically connect with printed circuit board (PCB) (as Fig. 7), and this mode is commonly called as surface adhering assembly (SMD).In another preferred embodiment, a side conducting terminal 12 of electric connector 10 ' extends to first outer row's terminals 122 of insulating body 2 and second row's terminal 124 and is set in parallel and does not have bending, as shown in Figure 3.Yet this mode is referred to as connecting element (DIP).

In addition, in preferred embodiment, insulating body 2 one sides more are provided with 2 reference columns 14, for locating usefulness with printed circuit board (PCB) (figure does not illustrate), as shown in Figure 1.

Another preferred embodiment of the present utility model is shown in Fig. 4～5.It is the electric connector 20 that a kind of female body 22, male body 40 cooperatively interact, for being connected with at least one printed circuit board (PCB).The utility model electric connector 20 comprises the male body terminal 48 of a female body 22, female body terminal 32, the one male body 40 of complex root and complex root at least.Wherein, female body 22 has a plurality of holes 24, first groove 26 and a slotted eye 28.Above-mentioned hole 24 is communicated with slotted eye 28 respectively.And hole 24 further comprises first group of

hole

242 and 244, the first groups of holes 242 of second group of hole and second group of hole 244 and lays respectively at groove 26 both sides.The female body terminal 32 of complex root is inserted in respectively in the above-mentioned hole 24.Above-mentioned female body terminal 32 comprises first row's terminal 322 and second row's terminal 324.Yet, these structures and relevant design, similar to preferred embodiment above, do not repeat them here.

As Fig. 4 and shown in Figure 5, male body 40 is assembled in the slotted eye 28 of female body 22.Please also refer to Fig. 6, male body 40 has a plurality of through holes 42 and one second groove 46 at least.Wherein, first groove 26 of female body 22 is corresponding with second groove 46 of male body 40.And the male body terminal 48 of complex root is inserted in respectively in the above-mentioned through hole 42.In preferred embodiment, first groove 26 and second groove 46 crosscut respectively run through female body 22 and male body 40, and all dark reaching to slotted eye 28 and through hole 42.Wherein, second groove 46 of male body 40 is except that with first groove 26 is corresponding, also for preventing to produce arc spark design.

In addition, above-mentioned male body terminal 48 more comprises a contact site 482 and an extension 484.When Damxung body 40 combined with female body 22, the contact site 482 of male body terminal 48 electrically connected with a side of female body terminal 32.Anticipate promptly, contact site 482 leading edges are provided with a plurality of tongue pieces 488, and just the side with the female body terminal 32 that extends to slotted eye 28 electrically connects, and forms the loop.In preferred embodiment, a plurality of tongue pieces 488 are for being two tongue pieces 488 of corresponding bending.And contact site 482 back segments are equipped with two button portions 486, for fixing, locate and use with above-mentioned through hole 42.

Yet, it should be noted that it is SMD or DIP that above-mentioned female body terminal 32 is looked the mode that electrically connects with printed circuit board (PCB), and be designed to the kink 36 of tool bending or not the tool bending be parallel form of terminal each other.Yet, the connected mode of SMD only is described at this.Please also refer to shown in Fig. 7,8, it illustrates the enforcement view that the utility model connects printed circuit board (PCB).Electric connector 20 can electrically connect with two printed circuit board (PCB) F, P respectively.Be respectively equipped with at least one first reference column 34 and one second reference column 50 at female body 22 with male body 40 a certain sides.In preferred embodiment, first reference column 34 and second reference column 50 all are provided with two, for locating with printed circuit board (PCB) F, P accurately.In addition, female body terminal 32 1 side ends, a promptly parallel end terminals with female body 22, and the extension 484 of male body terminal 48 is respectively with printed circuit board (PCB) F, P welding and fix.

Therefore, groove 6/ first groove 26/ second groove 46 that 10,20 crosscuts of the utility model electric connector run through can effectively reduce really, even can prevent to produce arc spark because of the high tension voltage that moment produces, and security of products and reliability are increased.

More than explanation only is preferred embodiment of the present utility model, be not in order to limit the standard of essence technology contents of the present utility model, if any technology entity that other people are finished or assembly and the application's claim are defined as identical, or be a kind of change of equivalence, all be regarded as being covered by in this claim.
