DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-4 The utility model provides a new technical solution: a connection structure for a power cable joint, comprising a first power cable body 1, a first connector 2 is fixedly sleeved on the outer surface of the first power cable body 1, and a slide groove 3 is opened on the outer surface of the first connector 2;
[0022] The connecting mechanism is arranged on the first connecting head 2 . The connecting mechanism is used for connecting power cables. The connecting mechanism includes two springs 4 . Both springs 4 are fixedly installed in the inner wall of the slide groove 3 .
[0023] Furthermore, the connecting mechanism also includes two fixed plates 5 and a ring 6. The two fixed plates 5 are respectively fixedly installed on the right ends of the two springs 4, and the right surfaces of the two fixed plates 5 are both inclined. The outer surfaces of the two fixed plates 5 are fixedly sleeved with a ring 6, and the ring 6 is slidably connected to the slide groove 3.
[0024] Furthermore, two circular holes 7 are formed on the inner wall of the slide groove 3 , and round balls 8 are disposed in the two circular holes 7 .
[0025] Furthermore, a sealing groove 9 is formed on the inner surface of the first connector 2 .
[0026] Furthermore, the connecting mechanism further comprises a second power cable body 10 , which is arranged on the right surface of the first power cable body 1 , and a second connector 11 is fixedly sleeved on the outer surface of the second power cable body 10 .
[0027] Furthermore, the outer surface of the second connector 11 is provided with two card slots 12, the outer surface of the second connector 11 is provided with two card slots 12, the outer surface of the second connector 11 is fixed with a rubber sealing ring 13, and the outer surface of the rubber sealing ring 13 is provided with a groove 14.
[0028] When the connecting structure of the power cable joint is used, a leftward thrust is applied to the circular ring 6 to make it move to the left, and at the same time, the circular ring 6 drives the two fixed plates 5 fixedly mounted on the inner surface to move to the left. While moving to the left, the two fixed plates 5 apply pressure to the two springs 4 fixedly installed on the left surface to cause them to shrink. At this time, the two fixed plates 5 no longer block the two circular holes 7, and the two round balls 8 arranged in the two circular holes 7 are no longer under force. At this time, the second connecting head 11 is inserted into the inner surface of the first connecting head 2, and the two slots 12 opened on the outer surface of the second connecting head 11 are aligned with the two circular holes 7. At this time, no thrust is applied to the circular ring 6, and at the same time, the two springs 4 are no longer under force. The two springs 4 expand and apply a rightward thrust to the two fixed plates 5 fixedly installed on the right end to cause them to move to the right. At this time, the inclined surfaces of the two fixed plates 5 hit the two round balls 8 and make them move toward the opposite surface, so that they shrink into the first connecting head 2 and are clamped in the two slots opened on the outer surface of the inner second connecting head 11. 12 is fixed, and the installation is completed at this time. When it is necessary to disassemble it, the restriction of the two balls 8 on the second connector 11 can be released by repeatedly pushing the ring 6 to the left, and the second connector 11 can be pulled out for disassembly. During installation, the rubber sealing ring 13 is filled into the sealing groove 9 opened on the inner surface of the first connector 2, and the groove 14 opened by the rubber sealing ring 13 wraps the outer side of the first connector 2 to improve the sealing performance, so that the joint has good sealing performance. The connection structure for the power cable connector has the function of quick disassembly and assembly through a card connection. Compared with the traditional power cable connector connected by a bolt mechanism, this connection method can not only realize quick disassembly and assembly, but also is relatively simple to operate, can be quickly connected, and is more convenient. The connection structure for the power cable connector can seal the sealing parts of the first connector and the second connector through a rubber sealing ring, so that it has good sealing performance, can be better waterproof, and is more convenient.
[0029] Working principle: When the connecting structure of the power cable connector is used, a leftward thrust is applied to the circular ring 6 to make it move to the left. At the same time, the circular ring 6 drives the two fixed plates 5 fixedly sleeved on the inner surface to move to the left. While moving to the left, the two fixed plates 5 apply pressure to the two springs 4 fixedly installed on the left surface to cause them to shrink. At this time, the two fixed plates 5 no longer block the two circular holes 7, and the two round beads 8 set in the two circular holes 7 are no longer under stress. At this time, the second connector 11 is inserted into the inner surface of the first connector 2, and the two card grooves 12 on the outer surface of the second connector 11 are aligned with the two circular holes 7. At this time, no thrust is applied to the circular ring 6, and the two springs 4 are no longer under stress. The two springs 4 expand and press against the two springs fixedly installed on the right end. The two fixing plates 5 apply a rightward thrust to move it to the right. At this time, the inclined surfaces of the two fixing plates 5 hit the two balls 8 and move them toward the opposite surface, so that they shrink into the first connecting head 2 and are engaged with the two card grooves 12 opened on the outer surface of the inner second connecting head 11 for fixation. At this time, the installation is completed. When it needs to be disassembled, the restriction of the two balls 8 on the second connecting head 11 can be released by repeatedly pushing the ring 6 to the left, and the second connecting head 11 can be pulled out for disassembly. During installation, the rubber sealing ring 13 is filled into the sealing groove 9 opened on the inner surface of the first connecting head 2, and the groove 14 opened by the rubber sealing ring 13 wraps the outer side of the first connecting head 2 to improve the sealing performance, so that the joint has good sealing performance.
