Embodiment
Before the utility model is described in detail, should be noted that in the following description content, similar element represents with identical numbering.
Consult Fig. 1 to Fig. 4, the first embodiment of the utility model electric connector 100 comprises: an insulation shell 1 and multiple terminal 2.
Insulation shell 1 has multiple terminal groove 11 running through this insulation shell 1 respectively along a fore-and-aft direction D, and in each terminal groove 11, being provided with a projection 12 protruded by the internal face defining this terminal groove 11, this projection 12 has front stopper section 121 and the rear stopper section 122 laying respectively at two opposite sides along this fore-and-aft direction D.
Described multiple terminal 2 is arranged at described multiple terminal groove 11 respectively, and each terminal 2 has the diapire 21 and two sidewalls 22 that extend along this fore-and-aft direction D, this two side 22 toward each other and be connected to these diapire 21 both sides at intervals and jointly define an insertion space 23 with this diapire 21, and the diapire 21 of terminal 2 and two side 22 three have a front-end edge 201,202 respectively, the front-end edge 202 of this two side 22 is connected and copline with the front-end edge 201 of this diapire 21.In the present embodiment, the diapire 21 of each terminal 2 has a gap 211 backward extended along this fore-and-aft direction D by front-end edge 201, and this diapire 21 is divided into two symmetrical wall portion 212.The sidewall 22 that each wall portion 212 is connected with it forms an elastic arm jointly, and that is, this two side 22 and diapire 21 form two elastic arms side by side jointly, in order to contact with docking terminal (not shown).Moreover, the two side 22 of each terminal 2 also has one respectively away from the apical margin 221 of this diapire 21, and one connects this apical margin 221 and its front-end edge 202 and forms the hypotenuse 222 of rescinded angle, reduce the area of front-end edge 202 shared by the porch of terminal groove 11 of this two side 22 whereby, make docking terminal by front side of insulation shell 1 during upstream end pilot trench 11, there is in porch larger insertion space, thus the insertion space 23 making the easy insertion end pilot trench 11 of docking terminal and then can enter terminal 2 is docked with terminal 2.
Each terminal 2 also has two respectively by this two side 22 backward and the Location resilient piece 24 extended toward each other, and one is positioned at the junction surface 25 of tail end to connect a wire (not shown).Consult Fig. 5 to Fig. 8, when terminal 2 is assembled in insulation shell 1, projection 12 in each terminal groove 11 to be protruded out from the internal face of the diapire 21 towards corresponding terminal 2 toward this diapire 21 and between this two side 22, and the end of two Location resilient pieces 24 of this terminal 2 is towards the front stopper section 121 of this projection 12, prevents terminal 2 from moving and deviating from terminal groove 11 whereby backward.In other words, projection 12 is utilized to be locked by terminal 2 location.
Terminal 2 is assembled to insulation shell 1, is by terminal 2 set terminal pilot trench 11 by the rear side of insulation shell 1.Consult Fig. 9, if when terminal 2 is placed in tram, then the front-end edge 201,202 of terminal 2 can pass through projection 12 smoothly, can not be stopped by projection 12, and terminal 2 when advancing in terminal groove 11, this two Location resilient piece 24 (see Fig. 8) runs into projection 12 and can be strutted toward both sides by projection 12, after by projection 12, Location resilient piece 24 homing and relatively inside contracting, the front stopper section 121 (see Fig. 8) of projection 12 can be butted on when terminal 2 retreats, prevent terminal 2 from moving backward and deviating from terminal groove 11 whereby.
Consult Fig. 4, Figure 10 and Figure 11, if and the rear stopper section 122 of this projection 12 is not positioned at correct assembling position in order to this terminal 2 when assembling, then this rear stopper section 122 can be butted on one of them front-end edge 201,202 of the diapire 21 of this terminal 2 and two side 22 three mutually, is placed into this terminal groove 11 with this terminal 2 of backstop.As shown in Figure 10 for terminal 2 is placed into terminal groove 11 by turning 90 degrees in incorrect position relative to tram, then wherein namely the front-end edge 202 of a sidewall 22 can be butted on the rear stopper section 122 of projection 12 and be stopped cannot move forward again by projection 12.Similarly, as shown in figure 11, when terminal 2 is placed into terminal groove 11 by turnback in incorrect position relative to tram, then namely the front-end edge 201 of diapire 21 can be butted on the rear stopper section 122 of projection 12 and be stopped cannot move forward again by projection 12.Terminal 2 so can be avoided by the assembling of mistake, reach fool proof effect.In addition, U-shaped structure is formed because the diapire 21 of terminal 2 is connected with the front-end edge 201,202 of two side 22, the front-end edge 202 of each sidewall 22 is connected with the front-end edge 201 of diapire 21 and forms L shape structure in other words, compared to single laminated structure, U-shaped or L shape structure can have better structural strength, not easily damage is bent, to guarantee normal configuration can also be kept to re-assembly again after terminal 2 is mispluged when the front-end edge 201,202 of diapire 21 and sidewall 22 and projection 12 are clashed into.
Consult Figure 12 to Figure 17, second embodiment of the utility model electric connector 100 is roughly the same with the first embodiment, but, in a second embodiment, each terminal 2 has a Location resilient piece 24, and this Location resilient piece 24 is extended by this diapire 21 and stretches into this insertion space 23 backward, the function of this Location resilient piece 24 is identical with the first embodiment, all in order to be butted on the front stopper section 121 (see Figure 14) of projection 12 when terminal 2 retreats, prevent terminal 2 from moving backward and deviating from terminal groove 11 whereby.The assemble method of its terminal 2, foolproof function and the effect that can reach identical with the first embodiment, no longer repeat in this.
In sum, aforementioned projection 12 can stop terminal 2 upstream end pilot trench 11 and have foolproof function when terminal 2 abnormal assembling.And, compared to single laminated structure, the diapire 21 of the terminal 2 and front-end edge 201,202 of sidewall 22 takes the shape of the letter U or L shape structure can have better structural strength, not easily damage is bent, to guarantee normal configuration can also be kept to re-assembly again after terminal 2 is mispluged when the front-end edge 201,202 of diapire 21 and sidewall 22 and projection 12 are clashed into.Moreover aforementioned projection 12 can also match with Location resilient piece 24 and have locking function, with by spacing for terminal 2.
The foregoing is only embodiment of the present utility model; the scope of the utility model enforcement can not be limited with this; namely all simple equivalence changes done according to the utility model application protection range and patent specification content with modify, all still belong in scope that the utility model patent contains.
