Butt-mating durability has also been reduced. In addition, each connector of the prior art electrical connector combination has only one docking groove, so no matter when assembling or inserting, each pair of opposite connectors must be docked one by one, and the assembly process is cumbersome and time-consuming. .

The purpose of the utility model is to provide an electrical connector combination, through the modular arrangement of the electrical connector, the shortcomings of the single connectors in the prior art can be improved and the assembly time can be improved.

Another object of the present utility model is to provide an electrical connector combination that is resistant to plugging and unplugging and is stably docked and buckled.

The technical scheme of the electrical connector combination of the utility model is that the electrical connector combination includes a plug connector and a socket connector, wherein the insulating body of the plug connector is provided with a buckle block corresponding to the insulating body of the socket connector. A buckle arm is provided at the position of the buckle block, and the buckle-shaped buckle end is provided on the buckle arm for snap-fitting with the buckle block, so that the electrical connector assembly can achieve a stable positioning effect.

Another technical solution of the electrical connector combination of the utility model is that: the insulating body of the socket connector is provided with at least two injection-molded docking grooves, thereby providing the effect that multiple plugs and socket connectors can be assembled and docked at one time. A docking plate is arranged in the groove, and two rows of terminal receiving grooves are alternately arranged on the upper and lower surfaces of the docking board for accommodating the terminals therein.

Through the above technical solution, the electrical connector combination of the utility model can realize a stable butt joint combination, and has an efficient assembly effect that one socket connector can be butt joint with two plug connectors at the same time.

Below with reference to accompanying drawing, the utility model is further described in conjunction with embodiment.

Fig. 1 is a perspective view of the utility model.

Fig. 2 is a front view of the socket connector of the present invention.

FIG. 3 is a sectional view of the receptacle connector of the electrical connector combination shown in FIG. 1 along section A-A.

Please refer to Fig. 1 and Fig. 2, the electrical connector combination of the present invention includes a socket connector 1 and a plug connector 2, wherein the socket connector 1 includes an insulating body 10 and a conductive terminal 11, and the insulating body 10 is arranged parallel to each other. There are two docking slots 12, 13, and docking plates 14, 15 are respectively arranged in the docking slots 12, 13, and two rows of terminal receiving slots 16 are alternately arranged on the upper and lower surfaces of the docking plates 14, 15, for accommodating conductive terminals 11 , wherein the docking slot 12 can accommodate a larger number of conductive terminals 11 , while the docking slot 13 can accommodate a smaller number of conductive terminals 11 . In addition, a screw seat 17 is respectively provided on both sides of the insulating body 10, and a screw hole 18 is formed on the screw seat 17 for cooperating with a screw to fix the receptacle connector 1 on the printed circuit board. A buckle arm 19 is also provided on the top of the docking grooves 12 and 13 for fastening and positioning the receptacle connector 1 and the plug connector 2 (details will be described later). Since the receptacle connector 1 of the electrical connector combination of the present invention has two butt slots 12, 13 integrally formed and included in an insulating body 10, two plug connectors can be assembled to the receptacle connector 1 at a time, In order to achieve the purpose of increasing the timeliness.

The plug connector 2 also includes an insulating body 20 and conductive terminals 21, wherein the front end of the insulating body 20 is provided with a groove 22, and two rows of terminal receiving grooves 23 are alternately arranged along the upper and lower inner surfaces of the groove 22, and the conductive terminals 21 are accommodated in Inside the terminal receiving groove 23. In addition, a buckle block 24 is provided on the upper surface of the insulating body 20 for snap fit with the buckle arm 19 of the socket connector 1. When the socket connector 1 and the plug connector 2 are mated, the buckle arm 19 Can be buckled on one side of the fastening block 24 .

Please refer to FIG. 3 , which is a cross-sectional view along line A-A in FIG. 1 , wherein the buckle arm 19 of the insulating body 10 is provided with a buckle end 191 , and the buckle end 191 is hook-shaped. When the plug connector 2 is inserted into the receptacle connector 1 , the hook-shaped fastening end 191 is buckled on one side of the fastening block 24 on the plug connector 2 , so that the receptacle connector 1 and the plug connector 2 are firmly combined. It is worth mentioning that since both the buckle block 24 and the buckle arm 19 are made of plastic, they are wear-resistant and have good durability, so that they can withstand multiple insertions and extractions when they are docked with each other, and the service life is greatly increased. In addition, the buckle block 24 and the buckle arm 19 can also be respectively arranged on the two sides of the plug connector 2 and the mating slots 12 , 13 , which can also achieve the effect of a stable buckle.
