[0002] A stationary contact is a contact point in a switch, relay, or contactor that does not move with the actuator. The opposite is a moving contact. Stationary contacts are key components of high-voltage switches, and the switching on and off of high-voltage switches depends on them. Their service life determines the lifespan of the high-voltage switch, and thus the safe operation of the high-voltage power transmission and transformation network.

[0003] A Chinese patent document with publication number CN216849681U discloses a static contact assembly structure, which discloses that "it includes a static contact body, a turntable is provided on the top of the static contact body, a positioning plate is provided on the bottom of the static contact body, a threaded groove is opened inside the static contact body, a positioning rod is fixedly installed on the left side of the top of the positioning plate, a receiving column is fixedly installed on the right side of the top of the positioning plate, a through groove is opened inside the receiving column, a limit rod is provided inside the through groove, and sliding grooves are opened inside the receiving column on both sides of the through groove" and "when in use, when installing the static contact body 1, the turntable 3 is rotated, and the turntable 3 drives the threaded rod 4 to rotate, thereby causing the positioning plate 2 to drive the positioning rod 5 and the receiving column 8 to move upward, and the static contact body 1 is fixed under the action of the positioning rod 5 and the locking rod 6."

[0004] In the above scheme, when positioning the stationary contact body, the turntable drives the threaded rod to rotate so that the positioning rod and the clamping rod fix the stationary contact body. However, in this process, there is no matching limiting structure for the threaded rod to prevent its threaded connection from loosening.

[0005] Therefore, this utility model proposes a high-strength static contact with an installation limiting structure to solve the above problems. Utility Model Content

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 7 This utility model provides a technical solution: a high-strength static contact with an installation limiting structure, including a static contact body 1 and a movable insert 3 disposed on the bottom side of the static contact body 1. The movable insert 3 is movably inserted into the limiting cylinder 4 at the top of the positioning rod 5. A positioning rod 5 is also disposed on the top of the positioning plate 2, and a locking rod 6 is disposed on the bottom side of the static contact body 1. An auxiliary bearing 7 is provided on the top of the positioning plate 2. The auxiliary bearing 7 is connected to one end of the drive screw 8. The drive screw 8 is threadedly connected in the stationary contact body 1. A turntable 9 is fixedly provided at the top of the drive screw 8. The turntable 9 is fastened by a set stabilizing component.

[0018] In the process of rotating the drive screw 8 via the turntable 9 to position the stationary contact body 1, this solution uses a stabilizing component to lock the turntable 9, thereby securing the drive screw 8 and preventing it from loosening after tightening. This provides a good stabilizing and limiting effect for the positioning of the stationary contact body 1. In other words, the stabilizing and limiting effect of the stationary contact body 1 is achieved through the cooperation of the fastening thread 1004 and the auxiliary component.

[0019] According to the appendix Figure 2-4 As shown, the stabilizing component in this solution includes a fixing ring 1001 disposed on the top of the stationary contact body 1; the center of the fixing ring 1001 is on the same straight line as the axis of the drive screw 8, and anti-slip stripes 1002 are equidistantly arranged on the top surface of the fixing ring 1001; the stabilizing component also includes an auxiliary protrusion 1003 disposed on the side of the turntable 9, and a fastening post 1004 is threaded through the auxiliary protrusion 1003; a knob body 1005 is fixedly disposed on the top of the fastening post 1004, and a knob body 1005 is fixedly disposed on the top of the fastening post 1004. The outer wall of 005 is provided with an auxiliary protrusion 1006, which is used to improve the ease of rotating the knob body 1005; that is, after the drive screw 8 is tightened by rotating the turntable 9, the turntable 9 is locked by the fastening screw 1004, thereby locking the drive screw 8. That is, the fastening screw 1004 is rotated by the knob body 1005 until the bottom end of the fastening screw 1004 presses against the fixing ring body 1001, and anti-slip stripes 1002 are provided on the top of the fixing ring body 1001 to further improve the fastening stability.

[0020] From the appendix Figure 3 As can be seen from the diagram, this solution provides an auxiliary protrusion 1003 on the side of the turntable 9. The purpose of the auxiliary protrusion 1003 is twofold: firstly, to provide support for the fastening stud 1004, that is, the auxiliary protrusion 1003 is threadedly connected to the fastening stud 1004; secondly, the auxiliary protrusion 1003 also provides convenience when rotating the turntable 9, and minimizes the problem of slippage when rotating the turntable 9.

[0021] In combination with appendix Figure 5-7As shown, when the drive screw 8 is stabilized by the fastening thread 1004, an auxiliary component is used. The auxiliary component includes a docking head 1101 fixedly disposed at the center of the bottom end of the fastening thread 1004. The docking head 1101 is adapted to engage with the docking groove 1104 at the center of the top end of the rubber block 1102. The rubber block 1102 is a cylindrical block. That is, when the fixed ring 1001 is squeezed by the fastening thread 1004, this solution provides a rubber block 1102 at the bottom end of the fastening thread 1004 and an auxiliary cone tip 1103 at the bottom end of the rubber block 1102 to improve the pressing and anti-slip effect on the fixed ring 1001.

[0022] The anti-slip stripes 1002 on the top of the fixed ring 1001 are designed such that an anti-slip groove is formed between adjacent anti-slip stripes 1002. When the fixed ring 1001 is squeezed by the rubber block 1102 at the bottom of the fastening screw 1004, the auxiliary cone tip 1103 at the bottom of the rubber block 1102 may get stuck in the anti-slip groove between adjacent anti-slip stripes 1002, thereby further improving the locking effect of the fastening screw 1004 on the drive screw 8.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
