Example one

Referring to fig. 1 to 5, in a first embodiment of an automatically locking insulation piercing connector of the present invention, an automatically locking insulation piercing connector comprises two clamp plates 1 disposed correspondingly, a fixing plate 2 disposed below the two clamp plates 1 and corresponding thereto, two parallel slide grooves 3 formed on the upper surface of the fixing plate 2, a slide block 4 slidably mounted in each slide groove 3, a baffle 17 fixedly mounted on each side of the fixing plate 2 for blocking the ends of the two slide grooves 3, a rack 5 disposed above each slide groove 3 and parallel thereto, a lower surface of each rack 5 fixedly connected to the adjacent slide block 4, an upper surface of each rack 5 fixedly connected to the adjacent clamp plate 1, a gear 6 disposed between the two racks 5 and engaged with the two racks 5, a rotating shaft 7 coaxially mounted on the lower surface of the gear 6, the rotating shaft 7 is rotatably arranged on the fixed plate 2, and the bottom end of the rotating shaft 7 extends downwards to the lower part of the fixed plate 2. Through the mode of rack and pinion drive, can realize the control to two splint 1 simultaneously, and then realize the centre gripping to leading wire and lead wire. The inner side surfaces of the two clamping plates 1 are provided with anti-skidding teeth. The anti-slip teeth are mainly used for increasing the friction force between the inner side surface of the splint 1 and the main guide wire and the lead wire.

The cover is equipped with a ring 9 of coaxial setting with it on the 7 axis bodies of pivot of fixed plate 2 below, 8 fixed connection on fixed plate 2 are passed through at ring 9 top through a plurality of connecting plate, 7 axis body surfaces of pivot in the ring 9 have two telescopic links that the symmetry set up along circumference fixed mounting, the terminal inner wall with ring 9 in the telescopic link outside contacts, two jacks 15 corresponding with telescopic link motion trail are seted up along circumference to ring 9 inner wall, jack 15's internal diameter is greater than the maximum diameter of telescopic link, 7 bottom fixed mounting in pivot has a hexagonal post 16, equal fixed mounting has a fixture block 18 on 17 lateral surfaces of every baffle, fixture block 18's effect mainly makes things convenient for constructor's use tools to live this anchor clamps.

When the invention is used, when a main guide wire and a lead wire are clamped and fixed by two clamping plates 1, a constructor only needs to clamp a clamping block 18 by using a special tool rod to prevent the clamp from moving, then a hexagonal column 16 is sleeved by using a long rod with a hexagonal sleeve at the front end below the clamp, then the hexagonal column 16 is rotated, the hexagonal column 16 drives a rotating shaft 7 to rotate, the rotating shaft 7 drives a gear 6 to rotate, the gear 6 drives racks 5 which are meshed with the two sides of the gear to move towards the middle part, so that the two clamping plates 1 are driven to approach towards the middle part to clamp the main guide wire and the lead wire, meanwhile, the rotating shaft 7 drives the two telescopic rods to synchronously move, when the two telescopic rods move to the insertion holes 15 and are inserted into the insertion holes 15, the rotating shaft 7 can be locked, so that the gear 6 and the gear racks 5 are locked, and the two clamping plates 1 can keep the state that the main guide wire and, the nut does not need to be frequently screwed down by using tools in the whole process, and time and labor are saved.

Example two:

referring to fig. 3, 4, 6, and 7, as another preferred embodiment of the present invention, the difference from embodiment 1 is that the telescopic rod includes a sleeve 10, an insertion rod 11, through grooves 12, bolts 13, and an elastic element 14, two sleeves 10 symmetrically disposed are fixedly mounted on the surface of the shaft body of the rotating shaft 7 in the circular ring 9 along the circumferential direction, two through grooves 12 symmetrically disposed are circumferentially disposed on the outer surface of each sleeve 10, an insertion rod 11 is inserted in each sleeve 10, the outer ends of the insertion rods 11 are respectively abutted against the inner wall of the circular ring 9, an elastic element 14 is disposed between the bottom end of each insertion rod 11 and the bottom of each sleeve 10, a bolt 13 is disposed on each insertion rod 11 in a threaded manner, and both ends of each bolt 13 extend outward until the bolt passes through the corresponding through grooves 12 and then extends out of each sleeve 10. The elastic element 14 is a spring.

When the telescopic rod is not inserted into the insertion hole 15, due to the acting force of the inner wall of the circular ring 9 on the insertion rod 11, the insertion rod 11 applies acting force on the elastic element 14 to compress the elastic element, when the rotating shaft 7 drives the telescopic rod to move to the insertion hole 15, the elastic element 14 pushes out the insertion rod 11, the insertion rod 11 is inserted into the insertion hole 15, and at the moment, the rotating shaft 7 is locked.

Through setting up rack and pinion mechanism, the telescopic link, the ring etc., it is to leading wire and lead wire reduction centre gripping to utilizing splint, only need to utilize the front end to be provided with hexagonal telescopic stock entangle the hexagonal post, rotate the hexagonal post after that, the hexagonal post drives the pivot rotation, the pivot drives the gear rotation, gear drive both sides and the rack of meshing with it move to the middle part, thereby drive two splint to draw close to in order to carry leading wire and lead wire to the middle part, in this moment, the pivot drives two telescopic link synchronous motion, move to jack department when two telescopic links, and when inserting in the jack, just can die the pivot lock, thereby with the gear, the rack lock dies, and then make two splint can keep the post to clamp the state of leading wire and lead wire, the whole in-process does not need the use tools to carry out frequent screwing up operation to the nut, more labour saving and time saving.
