Then, the process through holes on the connecting component A-2 are respectively aligned and sleeved forward and passed through the cable terminals of the metal strip A on the connecting component A-1 and in place. Then, through the alignment guidance of the pull distance spacer plate and the mating positioning boss on the terminal positioning part A, the terminal positioning part A is aligned and sleeved onto the cable terminals of the metal strip A on the connecting component A-1 and simultaneously inserted into the mating positioning groove on the connecting component A-2 and in place. Then, the assembly locking bolts A (26) are respectively aligned and inserted into the assembly locking bolt A through holes on the terminal positioning part A and screwed into the assembly locking bolt A mating holes on the connecting component A until in place and tightened. Finally, the internal thread of the control part on the assembled wiring auxiliary part is aligned and screwed into the thread on the outer wall of the connecting component A-2 until in place, thus assembling the main part A of the roller type connector;Then, three metal strips B (of course, the number of which should match the number of metal strips A on the main part A of the roller - type connector) are respectively inserted into the mating slots of the metal strips B on the connecting part B - 1 in place according to the process requirements. Then, the connecting part B - 1 is inserted forward into the mating positioning groove on the connecting part B - 2 in place according to the process requirements through the mating positioning boss on it. Then, through the alignment guidance of the extraction - distance spacer plate on the terminal positioning part B and the mating positioning groove, the terminal positioning part B is inserted backward into the mating positioning boss on the connecting part B - 2 in place according to the process requirements. Finally, the assembly locking bolt B (31) is inserted into the through - hole of the assembly locking bolt B on the terminal positioning part B and screwed into the mating hole of the assembly locking bolt B on the connecting part B in place and tightened, thus assembling the main part B (30) of the roller - type connector. Before use, first unscrew and remove the wiring auxiliary part from the connecting part, and separate the positioning locking and sealing kit composed of the deformable opening pawl part and the plastic - sealed deformable inner lining from the control part. Then, the external wiring cables are respectively inserted through the through - holes of the external wiring cables on the control part and the positioning locking and sealing kit in place according to the process requirements and in sequence. Then, the cable ends of the external wiring cables are respectively inserted through the through - holes of the external wiring cables on the terminal positioning part A and into the cable wiring terminal holes of the metal strips A in place according to the process requirements. Then, they are tightened and locked by screwing the locking bolts (54) for pressing the cables that match the wiring terminals. Finally, the wiring auxiliary part is screwed into the thread on the outer wall of the connecting part in place and tightened [At this time, due to the mating and screwing of the wiring auxiliary part and the connecting part, the gradually - pressing and tightening boss on the control part that matches the positioning locking and sealing kit moves forward, forcing the deformable opening pawls on the deformable opening pawl part to deform and close, and at the same time pressing the plastic - sealed deformable inner lining to deform and closely adhere to the external wiring cable, positioning, locking and sealing the external wiring cable], thus assembling the main part A of the roller - type connector for standby;Then, align the external connection cables in the device or switchgear cabinet according to the process requirements, pass them through the reserved holes on the outer wall of the device or switchgear cabinet from inside to outside and place them in position. Next, align the ends of each cable of the external connection cable according to the process requirements, sequentially pass them through the through holes for the external connection cable on the terminal positioning part B, and respectively insert them into the cable connection terminal holes of the metal strip B and place them in position. Then, tighten and lock them by screwing the locking bolts for pressing the cable that match the connection terminals. Finally, align and insert the main part B of the cone-type connector with the connected external connection cables into the reserved holes on the outer wall of the matching device or switchgear cabinet according to the process requirements and place them in position. Connect the main part B of the cone-type connector with the device or switchgear cabinet as a whole by aligning and matching with the through holes on the panel through the mounting bolts for use after installation. When in use, first, manually align and insert the guiding positioning boss and guiding positioning column on the connecting part A of the main part A of the cone-type electrical connector into the guiding positioning groove and guiding positioning hole on the main part B of the cone-type electrical connector (at this time, the cone-type protection boss of the connection contact B on the connecting part B also smoothly enters the entrance and exit of the cone-type protection boss of the connection contact B on the connecting part A). Then, apply a pressing force to the main part A of the cone-type electrical connector relative to the main part B of the cone-type electrical connector. Through the coordinated cooperation between the connecting part A (6) and the connecting part B (35), force the spring-fixed sliding partition to slide backward, compress the compression spring that cooperates with it and place it in position. Then, rotate the main part A of the cone-type electrical connector clockwise around the center of the circle of the main part A of the cone-type electrical connector and place it in position (the entire process of insertion and rotation is accurately in place under the guidance of the guiding positioning mechanism, etc.). After reaching the position, release the pressing force, and rely on the resilience of the spring-back type telescopic mechanism to force the main part A of the cone-type electrical connector to retreat and place it in position, so that the connection contact A on the main part A of the cone-type electrical connector meshes with the connection contact B on the main part B of the cone-type electrical connector to complete the connection and conduction. When removing, just press the main part A of the cone-type electrical connector forward to the in-place position and reverse-rotate it to the in-place position to pull it out (after applying the pressing force, due to the forward movement of the guiding positioning column on the connecting part A of the main part A of the cone-type electrical connector through the mutual cooperation with the guiding positioning hole on the connecting part B, force the spring-fixed sliding partition that cooperates with the connecting part A to compress the compression spring on the spring-back type telescopic mechanism. After reaching the position, reverse-rotate the main part A of the cone-type electrical connector so that the guiding positioning boss on it rotates along the guiding positioning groove on the main part B of the cone-type electrical connector to the side wall (41) of the guiding positioning groove and contacts it, then it can be pulled out). In the figure, (1) is a cone-type electrical connector for the emergency power supply of a subway station and subway tunnel.
