Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, specifically a conductor crimping rod. Background Technology

[0002] The conductor crimping rod is a key metal component in GIS cable terminals used to connect the cable to the internal conductive circuit of GIS equipment. It is usually made of copper or aluminum alloy and achieves physical and electrical connection with the cable conductor through a crimping process. The conductor crimping rod mainly consists of a tubular crimping part and a cylindrical conductive part with an annular limiting groove. A spring contact finger is installed at the annular limiting groove to conduct electricity.

[0003] Existing conductor crimping rods are usually one-piece structures. When installing spring contacts, the spring contacts need to undergo a large degree of deformation to be installed in the limiting groove. However, the spring contacts have a large elastic force, so a large force needs to be applied during installation to overcome the elastic force of the spring contacts. This makes the installation of spring contacts difficult and can easily damage them. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 5This utility model provides a technical solution: a conductor crimping rod, including a connecting rod 1, with a connecting hole 12 penetrating through the middle of the connecting rod 1, and a connecting cylinder 3 threadedly connected to the top of the connecting rod 1. Conductive grease is applied between the connecting cylinder 3 and the connecting rod 1, and between the conductive part 4 and the connecting cylinder 3, to reduce contact resistance. The connecting rod 1, the connecting cylinder 3, and the conductive part 4 are all made of aluminum alloy. The conductive part 4 is threadedly connected to the connecting cylinder 3, allowing both the conductive part 4 and the connecting cylinder 3 to be detached. When installing the spring contact finger, the conductive part 4 and the connecting cylinder 3 are first disassembled, and then the spring contact finger is installed from bottom to top on the outside of the recess 13. Because the lower volume of the conductive part 4 and the connecting cylinder 3 is small, the spring contact finger does not need to undergo a large degree of deformation during installation, reducing the difficulty of installing the spring contact finger. Both the outer sides of the cylinder 3 and the conductive part 4 are provided with recessed parts 13. A first limiting groove 5 is formed between the connecting cylinder 3 and the conductive part 4, and a second limiting groove 6 is formed between the connecting cylinder 3 and the connecting rod 1. Both the first limiting groove 5 and the second limiting groove 6 are used to limit the spring contact finger and prevent the spring contact finger from deviating. The outer side of the connecting rod 1 is provided with a fixing screw hole 7 that communicates with the wiring hole 12. There are two fixing screw holes 7, which are distributed crosswise on the outer side of the connecting rod 1. The crosswise distribution of fixing screw holes 7 allows the torque bolt 2 to apply force crosswise, thereby improving the fixing effect of the torque bolt 2. The fixing screw hole 7 is threaded with a torque bolt 2. The torque bolt 2 is used to press the cable conductor, so that the connecting rod 1 is fixed to one end of the cable conductor, thereby eliminating the need for the traditional crimping method and improving the convenience of connection.

[0019] The top of the inner wall of the wiring hole 12 is provided with a first internal thread hole 8, and the outer side of the connecting cylinder 3 is provided with a first external thread 9 that mates with the first internal thread hole 8. The connecting cylinder 3 is threadedly connected to the wiring rod 1 through the first internal thread hole 8 and the first external thread 9.

[0020] The connecting cylinder 3 has a second internal threaded hole 11 in the middle, and the conductive part 4 has a second external thread 10 that mates with the second internal threaded hole 11 on the outside. The conductive part 4 is threadedly connected to the connecting cylinder 3 through the second external thread 10 and the second internal threaded hole 11.

[0021] The torque bolt 2 includes a bolt body 21 that is threadedly connected to the fixing screw hole 7. One end of the bolt body 21 is connected to a twist-off part 22, and a head 23 is provided on one side of the twist-off part 22. When fixing, an electric wrench is used to rotate the torque bolt 2 to tighten the cable conductor. When a certain torque is reached, the connection between the twist-off part 22 and the bolt body 21 will break, causing the head 23 and the twist-off part 22 to separate from the bolt body 21. The bolt body 21 is completely inside the fixing screw hole 7 and will not protrude from the surface of the connector 1.

[0022] The twisted part 22 is a frustum structure. The large end face of the twisted part 22 is connected to the head 23, and the small end face of the twisted part 22 is connected to the bolt body 21, so that when the twisted part 22 is twisted off, it will break at the connection between the twisted part 22 and the bolt body 21.

[0023] Specifically, when installing the spring contact finger, disassemble the connecting cylinder 3 from the conductive part 4, and then install the spring contact finger from bottom to top on the outside of the recessed part 13. After the spring contact finger is installed on the outside of both the connecting cylinder 3 and the conductive part 4, apply conductive paste to the surface of the first internal thread hole 8, the first external thread 9, the second external thread 10, and the second internal thread hole 11. Then connect the connecting cylinder 3 to the connecting rod 1, and then connect the conductive part 4 to the connecting cylinder 3 to complete the installation of the spring contact finger. When connecting to the cable conductor, put the connecting rod 1 through the connecting hole 12 onto one end of the cable conductor, so that one end of the cable conductor is pressed against the conductive part 4. Then use an electric wrench to rotate the torque bolt 2. The torque bolt 2 presses the cable conductor. When a certain torque is reached, the connection between the twisted part 22 and the bolt body 21 will break, so that the head 23 and the twisted part 22 are separated from the bolt body 21, and the connection is completed.
