At above-mentioned technical problem, therefore, necessary electric connector is carried out improvement design, to satisfy the needs of electric connector development.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and it has the stable conducting terminal of fixing.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, the plurality of conductive terminals that it comprises the insulating body of the docking section that is provided with base portion and docks the direction extension from the base portion front end edge and is assembled in insulating body along the butt joint direction, described base portion has the terminal channel that passes and have opening backward for conducting terminal, described docking section has the some accepting grooves with described terminal channel conducting, described conducting terminal comprises the flat part that is assembled in base portion and is used to weld cable, be immobilizated in the holding parts of described terminal channel and the shell fragment shape contact site that extends forward along the butt joint direction from holding parts, described holding parts comprises a pair of perpendicular arm perpendicular to flat part, and each perpendicular arm has and aforementioned terminal channel fixing and highly different first projection and second projections
Compared with prior art, the utility model electric connector has following beneficial effect: described first, second projection makes the conducting terminal assembling easily, and not fragile and fixing is stablized.

Fig. 1 is the three-dimensional combination figure of the utility model electric connector.
Fig. 2 is the part assembling schematic diagram of electric connector shown in Figure 1.
Fig. 3 is the unit assembly drawing of another angle shown in Figure 2.
Fig. 4 is the cutaway view along A-A shown in Figure 1.
[embodiment]
Extremely shown in Figure 5 as Fig. 1, the utility model electric connector 100, it comprises insulating body 1, is contained in row's conducting terminal 2 of insulating body 1 and the stopper 3 that is assembled in insulating body 1.
As Fig. 2, shown in Figure 3, conducting terminal 2 is made for electric conducting material, and it comprises horizontal-extending and is used to weld the flat part 21 of cable (not shown), extends forward and be immobilizated in the U-shaped holding parts 22 of terminal channel 114 and a pair of shell fragment shape contact site 23 that extends forward from holding parts 22 from flat part 21.Flat part 21 is contained in the rectangular channel 115 of insulating body 1, and holding parts 22 comprises linking arm 221 that connects flat part 21 and a pair of perpendicular arm 222 that extends vertically upward from linking arm 221 both sides, and the fin 1144 of insulating body 1 is between two perpendicular arms 222.Each perpendicular arm 222 upper end is provided with wedge shape first projection 2221, second projection, 2222, the first projections 2221 and is positioned at the front of second projection 2222 and lower than second projection 2222.When conducting terminal 2 insertion end subchannels 114, front portion 1142 interference engagement of the roof 1141 of first projection 2221 and terminal channel 114, rear portion 1143 interference engagement of second projection 2222 and roof 1141 then, so can make conducting terminal 2 be easy in the insertion end subchannel 114 and not fragile, and fixing is stable.Two contact sites 23 protract forward from the front end of two perpendicular arms 222 respectively, and its extension trend is separately extended gradually for drawing close gradually when its spacing only can hold butt joint terminal (not shown) insertion of butt connector again.The transverse width of described conducting terminal 2 and vertical terminal channel 114 width of height and insulating body 1 and highly all close.
During assembling, one row's conducting terminal 2 inserts in the accepting groove 121 from the terminal channel 114 of the body 1 that insulate respectively along the butt joint direction, the contact site 23 of conducting terminal 2 is contained in the accepting groove 121, holding parts 22 is contained in the terminal channel 114, the perpendicular arm 222 of holding parts 22 is contained in the elongated slot 1145 of terminal channel 114, first projection 2221 of holding parts 22, second projection 2222 respectively with front portion 1142, rear portion 1143 interference engagement of the roof 1141 of terminal channel 114, flat part 21 is arranged in the rectangular channel 113 of insulating body 1.In second step, stopper 3 inserts in first groove 1111 of insulating body 1, the projection 34 and base portion 1 interference engagement of stopper 3.In the 3rd step, utilize glue that flat part 21 is retained on insulating body 1.In the 4th step, cable (not shown) is welded on the flat part 21.
