The process through holes on the component A-2 are aligned and inserted forward according to the process requirements and passed through the cable terminal with the metal strip A on the connecting component A-1 and put into place. Then, through the alignment guide of the pull-out spacing plate on the terminal positioning component A and the matching positioning boss, the terminal positioning component A is aligned and inserted into the cable terminal with the metal strip A on the connecting component A-1 and inserted into the matching positioning groove on the connecting component A-2 and put into place. Then, the assembly locking bolts A (26) are aligned and inserted into the assembly locking bolt A through holes on the terminal positioning component A and screwed into the assembly locking bolt A matching holes on the connecting component A and put into place and locked. Finally, the internal thread of the control component on the assembled wiring auxiliary component is aligned and screwed into the thread on the outer wall of the connecting component A-2 and put into place. The main component A of the toothed connector is assembled.Then, three metal strips B (of course, the number of them must match the number of metal strips A on the main part A of the toothed connector) are respectively inserted into the matching slots of the metal strips B on the connecting part B-1 according to the process requirements and put them in place. Then, the connecting part B-1 is inserted forward into the matching positioning groove on the connecting part B-2 through the matching positioning boss thereon according to the process requirements and put it in place. Then, through the pull-out spacer plate on the terminal positioning part B and the alignment guide of the matching positioning groove, the terminal positioning part B is inserted backward into the matching positioning boss on the connecting part B-2 according to the process requirements and put it in place. Finally, the assembly locking bolt B (31) is inserted into the assembly locking bolt B through hole on the terminal positioning part B and screwed into the assembly locking bolt B matching hole on the connecting part B until it is in place and locked. In other words, the main part B (30) of the toothed connector is assembled. Before use, first remove the wiring auxiliary parts from the connecting parts by reverse rotation, and separate the positioning locking sealing kit composed of the deformable opening pawl parts and the plastic sealing deformable lining from the control part. Then, align the external cables according to the process requirements and pass them through the external cable holes on the control part and the positioning locking sealing kit in sequence and put them in place. Then, align the ends of the external cables according to the process requirements and pass them through the external cable holes on the terminal positioning part A and insert them into the cable terminal holes of the metal belt A and put them in place. Then, through the compression wire matching the terminal, The locking bolt (54) of the cable is tightened and connected and locked, and finally the wiring auxiliary part is screwed into the thread of the outer wall of the connecting part into place and locked [at this time, due to the cooperative screwing of the wiring auxiliary part and the connecting part, the gradual pressure locking boss on the control part matching the positioning and locking sealing kit moves forward, forcing the deformable opening pawl on the deformable opening pawl part to deform and close, and at the same time compressing the deformable inner lining of the plastic seal to deform and fit tightly against the external cable, so that the external cable is positioned, locked and sealed], that is, the main part A of the toothed connector is assembled and ready for use;Then, the external cables in the equipment or switch cabinet are aligned according to the process requirements and passed through the reserved holes on the outer wall of the equipment or switch cabinet from the inside to the outside and into place. Then, the cable ends of the external cables are aligned according to the process requirements and passed through the external cable holes on the terminal positioning piece B in sequence and inserted into the cable terminal holes of the metal belt B and into place. Then, the locking bolts for clamping the cables that match the terminal blocks are tightened and connected and locked. Finally, the main part B of the tooth-type connector connected to the external cable is aligned according to the process requirements and inserted into the reserved holes on the outer wall of the matching equipment or switch cabinet and into place. The main part B of the tooth-type connector is connected to the equipment or switch cabinet as a whole by aligning the mounting bolts with the through holes on the panel, and the installation is ready for use. When in use, first manually align the guide positioning boss and the guide positioning column on the connecting part A of the toothed electrical connector main part A and insert them into the guide positioning groove and the guide positioning hole on the toothed electrical connector main part B (at this time, the toothed protective boss of the connecting contact B on the connecting part B is also aligned and smoothly enters the entrance and exit of the toothed protective boss of the connecting contact B on the connecting part A), and then apply a top pressure to the toothed electrical connector main part A relative to the toothed electrical connector main part B, and through the coordination between the connecting part A (6) and the connecting part B (35), force The spring-fixed sliding partition slides backward to compress the compression spring matched with it and put it in place, and then the main part of the toothed electrical connector A is rotated clockwise with the center of the circle of the main part of the toothed electrical connector A as the axis and put into place (the whole insertion and rotation process is accurately and correctly put into place by the guidance of the guide positioning mechanism, etc.), and the top pressure is released after it is in place, and the rebound force of the rebound telescopic mechanism is used to force the main part of the toothed electrical connector A to retreat and put it in place, so that the connection contact A on the main part of the toothed electrical connector A and the connection contact B on the main part of the toothed electrical connector B are engaged with each other to complete the connection and conduction. When removing, the main part A of the toothed electric connector is pushed forward to the position and then rotated back to the position to be pulled out (after applying the pushing pressure, the guide positioning column on the connecting part A of the main part A of the toothed electric connector moves forward through the mutual cooperation with the guide positioning hole on the connecting part B, forcing the spring fixed sliding partition matched with the connecting part A to compress the compression spring on the rebound telescopic mechanism. After it is in place, the main part A of the toothed electric connector is rotated in the reverse direction so that the guide positioning boss on it rotates along the guide positioning groove on the main part B of the toothed electric connector to the side wall (41) of the guide positioning groove and contacts it, and then it can be pulled out). The figure (1) shows a toothed electric connector for emergency power supply of subway stations and subway tunnels. ;
