Description

Technical Field

[0001] The utility model relates to the technical field of wiring devices, in particular to a wiring device for a box-type transformer substation. Background Art

[0002] A box-type substation is a place used to change voltage. Cable wiring is often required in the substation, which requires the use of a cable connector to organize external cables so that the external cables can be connected to the circuit inside the substation through the connector.

[0003] At present, the connector used in box-type substations is to strip the cable end and insert it into the connector, and use bolts to tighten the cable to complete the cable connection. In actual use, although the tightening by bolts can ensure the stability of the cable, with long-term use, since the cable is composed of multiple strands, the bolts can easily loosen the cable, affecting the normal connection and may also cause the cable to break at the compressed part, which has certain disadvantages. For this reason, we propose a wiring device for box-type substations. Utility Model Content

[0004] The purpose of the present utility model is to provide a wiring device for a box-type substation to solve the problems raised in the above background technology.

[0010] The ring is used to support the push rod;

[0011] The limiting portion is used to limit the circular ring. After the clamping plate has finished fixing the cable, the restriction on the circular ring is released, so that the circular ring and the gear ring rotate together.

When the gear ring rotates, the gear ring can push the push rod to move to the side close to the center of the ring through the support rod, and the push rod can move together with the splint through the connecting rod, so that the splint contacts the cable to fix the cable. When the ring is not restricted, the gear ring can push the ring to rotate together through the support rod and the push rod, and the cable fixed by the splint can rotate together, so as to tighten the cable and prevent the cable from being loose and affecting the connection.

[0029] like Figures 1-9 As shown, the utility model provides a technical solution: a wiring device for a box-type substation, comprising a junction box 1, a wiring mechanism is provided inside the junction box 1, the wiring mechanism consists of a fixing part 2 and a limiting part 3, a control component 4 is provided on the junction box 1, the fixing part 2 comprises: a gear ring 21, a clamping plate 22, a push rod 23, a connecting rod 24, a support rod 25, and a circular ring 26, the limiting part 3 is used to limit the circular ring 26, after the clamping plate 22 fixes the cable, the restriction on the circular ring 26 is released, so that the circular ring 26 rotates together with the gear ring 21.

[0030] A partition plate 5 is fixed inside the junction box 1, a through hole 6 is opened on the partition plate 5, a groove is opened on the front of the partition plate 5, a gear ring 21 is rotatably mounted on the front of the partition plate 5, a ring 26 is rotatably mounted in the groove on the front of the partition plate 5, a push rod 23 passes through the ring 26 and is slidably connected to the ring 26, a connecting rod 24 is fixed to the top of the splint 22, the connecting rod 24 passes through one end of the push rod 23 and is slidably connected to the push rod 23, and the other end of the push rod 23 is hinged with a support rod 25, and the end of the support rod 25 away from the push rod 23 is hinged to the gear ring. On the inner side of the wheel ring 21, when the gear ring 21 rotates, the gear ring 21 can push the push rod 23 to move to the side close to the center of the circular ring 26 through the support rod 25, and the push rod 23 can move together with the splint 22 through the connecting rod 24, so that the splint 22 contacts the cable to fix the cable. When the circular ring 26 is not restricted, the gear ring 21 can push the circular ring 26 to rotate together through the support rod 25 and the push rod 23, and the cable fixed by the splint 22 can rotate together, so as to tighten the cable and prevent the cable from becoming loose and affecting the connection.

[0031] The limiting portion 3 includes a limiting tooth 31, which is fixed in the groove on the front of the partition plate 5. A fixing rod 32 is fixed on the inside of the ring 26. The fixing rod 32 passes through the card rod 33 and is slidably connected to the card rod 33. A reset spring 34 is fixed on the side of the card rod 33 close to the fixing rod 32. The end of the reset spring 34 away from the card rod 33 is fixed on the inner wall of the ring 26. The bottom of the card rod 33 is hinged with a hinge rod 35. The end of the hinge rod 35 away from the card rod 33 is hinged with a vertical rod 36. The vertical rod 36 passes through the ring 26 and is slidably connected to the ring 26. The end of the vertical rod 36 away from the hinge rod 35 is fixed to the side of the splint 22 close to the push rod 23. A movable tooth 37 is provided on the ring 26. The movable tooth 37 passes through the ring 26 and is slidably connected to the ring 26. A support spring 38 is fixed to the end of the movable tooth 37 away from the limit tooth 31. The end of the support spring 38 away from the movable tooth 37 is fixed to the inner wall of the ring 26. A card slot 39 is provided on the side of the movable tooth 37 close to the card rod 33. The clamping rod 33 is stuck in the clamping groove 39 to limit the movable tooth 37, so that the movable tooth 37 is completely engaged with the limiting tooth 31, thereby limiting the ring 26. When the clamping plate 22 contacts the surface of the cable, the push rod 23 continues to move, and the clamping plate 22 and the push rod 23 gradually fit together. When the clamping plate 22 and the push rod 23 are completely fitted together, the cable is completely fixed. At this time, the clamping plate 22 moves with the vertical rod 36, and the vertical rod 36 pushes the clamping rod 33 away from the movable tooth 37 through the hinge rod 35. The movable tooth 37 is moved to one side, so that the card rod 33 is withdrawn from the card slot 39 on the movable tooth 37, thereby releasing the restriction on the movable tooth 37. At this time, when the movable tooth 37 and the limiting tooth 31 conflict with each other, the inclined surface of the tooth of the movable tooth 37 conflicts with the inclined surface of the tooth of the limiting tooth 31, so that the movable tooth 37 can move into the ring 26, thereby releasing the restriction on the ring 26. At this time, when the gear ring 21 continues to rotate, the gear ring 21 can drive the ring 26 to rotate together through the support rod 25 and the push rod 23.

[0032] The control component 4 includes a double-sided rack rod 41, which passes through the top of the junction box 1 and is slidably connected to the junction box 1. The double-sided rack rod 41 is engaged with the gear ring 21. A slot 42 is provided on the front of the double-sided rack rod 41. An L-shaped pull rod 43 is slidably installed on the top of the junction box 1. A fixing plate 44 is fixed on the top of the junction box 1. A connecting spring 45 is fixed between the L-shaped pull rod 43 and the fixing plate 44. When the double-sided rack rod 41 is pressed downward, the double-sided rack rod 41 can drive the gear ring 21 to rotate. When the slot 42 on the front of the double-sided rack rod 41 moves to the position of the L-shaped pull rod 43, the L-shaped pull rod 43 can be inserted into the slot 42 under the action of the connecting spring 45, thereby restricting the double-sided rack rod 41 and ensuring the stability of the overall device during use.

[0033] A terminal block 7 is provided inside the junction box 1. After the cables are inserted into the junction box 1, the cables pass through the through holes 6 on the partition plate 5 and come into contact with the terminal block 7, thereby completing the electrical connection between the two groups of cables.

[0034] In the present invention, when in use, the junction box 1 is installed on the box-type substation using bolts. When connecting the cables, the ends of the cables are peeled, and the two groups of cables are inserted into the junction box 1 respectively, so that the cables pass through the through holes 6 and abut against the terminal board 7, completing the electrical connection between the two groups of cables.

[0035] At this time, it is only necessary to press the double-sided rack rod 41 downward, and the double-sided rack rod 41 will drive the gear ring 21 to rotate when moving downward. Since the circular ring 26 is restricted by the limit part 3 at this time, the gear ring 21 can push the push rod 23 to move to the side close to the center of the circular ring 26 through the support rod 25, and the push rod 23 can move together with the splint 22 through the connecting rod 24, so that the splint 22 contacts the cable to fix the cable.

[0036] When the clamping plate 22 contacts the surface of the cable, the push rod 23 continues to move, and the clamping plate 22 and the push rod 23 gradually fit together. When the clamping plate 22 and the push rod 23 are completely fitted together, the cable is completely fixed. At this time, the clamping plate 22 moves with the vertical rod 36, and the vertical rod 36 pushes the clamping rod 33 to the side away from the movable tooth 37 through the hinge rod 35, so that the clamping rod 33 withdraws from the clamping groove 39 on the movable tooth 37, thereby releasing the restriction on the movable tooth 37. At this time, the movable tooth 37 and the push rod 23 are completely fitted together. When the limiting teeth 31 conflict with each other, the inclined surfaces of the teeth of the movable teeth 37 conflict with the inclined surfaces of the teeth of the limiting teeth 31, so that the movable teeth 37 can move into the ring 26, thereby releasing the restriction on the ring 26. At this time, when the gear ring 21 continues to rotate, the gear ring 21 can drive the ring 26 to rotate together through the support rod 25 and the push rod 23, and the cable fixed by the splint 22 can rotate together, thereby tightening the cable to prevent the cable from loosening and affecting the connection, and completing the connection of the cable.

[0037] When the cable needs to be disassembled, it is only necessary to pull the L-shaped pull rod 43 so that the L-shaped pull rod 43 withdraws from the slot 42 to release the restriction on the double-sided rack rod 41, and pull the double-sided rack rod 41 upward to reset it, so that the gear ring 21 can be controlled to rotate in the opposite direction. At this time, the vertical surface of the teeth of the limit tooth 31 and the vertical surface of the teeth of the movable tooth 37 conflict with each other, so that the ring 26 cannot rotate in the opposite direction. At this time, the gear ring 21 can pull the push rod 23, the connecting rod 24 and the clamping plate 22 to reset through the support rod 25, thereby loosening the fixation of the cable and the cable can be pulled out.

[0038] After the clamping plate 22 is completely reset, the clamping plate 22 is not interfered with. Under the action of the reset spring 34, the clamping rod 33 moves to the side close to the movable tooth 37 and is inserted into the clamping groove 39 to restrict the movable tooth 37, thereby completing the reset.

[0039] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
