Detailed ways:

In order to enable the review committee to have a further understanding of the purpose, features and functions of the present utility model, the preferred embodiments are hereby given in detail with the accompanying drawings as follows:

Please refer to Fig. 1 to Fig. 7, which are structural schematic diagrams of preferred embodiments of the present utility model. The utility model relates to a plug-and-pull electrical connector, which is composed of an insulating main body 10, a digital terminal 20. The rear cover 30 and the housing 40 are combined.

As shown in Figure 5, the front end of the insulating body 10 forms a plug-in end for the contact portion of the terminal to be placed. The insulating body 10 is also provided with a corresponding terminal assembly hole 13 for the terminal to be fixed and assembled. The left and right side walls 11 extending rearward and the guard plates 12 inside the left and right side walls 11 are provided with terminal protection slots 121 on the guard plates 12 , and the left and right side walls 11 are provided with cutaway buckle slots 111 .
