Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a wiring terminal, including link 1 and with link 1 integrated into one piece's flat end 2, it has logical groove 3 to open on flat end 2. The connection end 1 includes a fixing portion 4 and a covering portion 5, and a connection slot 6 for inserting a cable is formed between the fixing portion 4 and the covering portion 5.

Referring to fig. 1 and 2, sliding blocks 7 are fixedly connected to two ends of the fixing portion 4 facing the covering portion 5, sliding grooves 8 into which the sliding blocks 7 are inserted are formed in two ends of the covering portion 5, and the sliding blocks 7 are slidably connected in the sliding grooves 8. The rubber layer 12 is fixedly connected to one surface, facing the covering portion 5, of the fixing portion 4, the rubber layer 12 and the sliding block 7 are arranged in a staggered mode, the rubber layer 12 has the effect of reducing electric wire leakage in the wiring groove 6, the possibility that workers contact with cables inserted into the wiring groove 6 is reduced through the non-conductivity of the rubber layer 12, and the potential safety hazard is reduced when the wiring terminals are used. Fixedly connected with stopper 13 on the one side of rubber layer 12 is kept away from to sliding block 7, stopper 13 integrated into one piece and the both sides of sliding block 7, and stopper 13 and the equal sliding connection of sliding block 7 are in sliding tray 8. After the sliding block 7 and the limiting block 13 are inserted into the sliding groove 8 together by the worker, the metal sheets are welded at the two ends of the notch of the sliding groove 8 of the covering part 5, and the sliding block 7 and the limiting block 13 are limited through the metal sheets. When the staff will insert the cable to the wiring groove 6 in, the staff holds the one end fixed connection's that the portion 5 is closed to the lid earlier and draws piece 17, draws the portion 5 that closes 5 orientation and keep away from fixed part 4 through drawing piece 17, and the metal sheet that closes 5 portion 5 with the welding up to stopper 13 and welding carries out the butt, closes 5 portion through the welding and restricts sliding block 7 and stopper 13's displacement through the welding. When the staff moves the covering part 5, the covering part 5 is prevented from being separated from the fixing part 4, and the operation difficulty of connecting the subsequent covering part 5 and the fixing part 3 is increased.

Referring to fig. 2 and 3, the inner side wall of the covering part 5 facing the notch of the wire connecting groove 6 is fixedly connected with the teeth 14, and the teeth 14 are uniformly arranged along the radial direction of the notch of the wire connecting groove 6. After the cable is placed in the wiring groove 6 and the covering part 5 moves towards the fixing part 4, the biting teeth 14 contact with the outer surface of the cable along with the movement of the covering part 5, the cable inserted into the wiring groove 6 is relatively fixed through the biting teeth 14, and even if the cable is pulled by misoperation of an operator, the stability of a part of the cable positioned in the wiring groove 6 can be ensured through the biting teeth 14. And the end of the teeth 14 which is first contacted with the cable or wire is a circular arc end 15. When the teeth 14 fix the cable, the arc ends 15 can slow down the damage of the teeth 14 to the outer surface of the cable, and the service life of the cable can be prolonged.

Referring to fig. 3 and 4, a first splice plate 9 is fixedly connected to two ends of the fixing portion 4, a second splice plate 10 is fixedly connected to two ends of the covering portion 5, and a fixing bolt 11 is in threaded connection with the first splice plate 9 and the second splice plate 10. After the cable is inserted into the wiring slot 6 and is fixed by the teeth 14, the worker makes the first splicing plate 9 and the second splicing plate 10 approach to each other, and fixes the first splicing plate 9 and the second splicing plate 10 by using the fixing bolt 11, so that the fixing part 4 and the covering part 5 are relatively fixed by the threaded connection of the fixing bolt 11. The second splice plate 10 is further provided with a recessed groove 16 for inserting a bolt head of the fixing bolt 11, and after the fixing bolt 11 fixes the first splice plate 9 and the second splice plate 10, the bolt head of the fixing bolt 11 is located in the recessed groove 16 and the bolt head of the fixing bolt 11 is lower than or level to the outer surface of the second splice plate 10. This makes external article or staff all be difficult for with the bolt head contact of fixing bolt 11 for fixing bolt 11 is difficult for taking place to rotate, further promotes the stability of being connected between fixed part 4 and the portion 5 that closes of lid.

Referring to fig. 1, a conductive paste is further applied to the inner sidewalls of the wire-connecting groove 6, and the conductive paste located in the wire-connecting groove 6 has a certain thickness. When the cable is placed in the wiring groove 6, the conductive paste can coat the periphery of the cable, so that the conductivity of the cable is improved.

The implementation principle of the embodiment is as follows: when needing to use binding post to fix the cable, the staff closes portion 5 and fixed part 4 separation with the lid through drawing piece 17 earlier, insert the cable again to fixed part 4 and the lid closes the wiring groove 6 that forms between the portion 5 in, later with lid close the portion 5 and move towards the direction of fixed part 4 for the tooth 14 contacts and makes first splice plate 9 and second splice plate 10 contact with the cable, twist fixing bolt 11 on first splice plate 9 and second splice plate 10 at last, in order to realize fixed part 4 and the relative fixed connection that the lid closed portion 5.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
