[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a high temperature resistant wire connector of the utility model comprises a U-shaped rod 1, both end surfaces of the U-shaped rod 1 are provided with mounting grooves, a conductive rod 12 connected to the mounting groove is installed inside the bending part of the U-shaped rod 1, a conductive cylinder 11 connected to the conductive rod 12 is installed inside the mounting groove, a plurality of pressing pieces 10 for clamping the wires are installed on the open end surface of the conductive cylinder 11, strip openings 2 are provided on the outer wall surfaces at both ends of the U-shaped rod 1 opposite to the pressing piece 10, a guide part 3 is protruded to form the outer ring surface of the pressing piece 10, the guide part 3 is arranged through the strip opening 2, an extrusion ring 4 is sleeved on the outside of the U-shaped rod 1 located on the conductive cylinder 11, and an adjustment mechanism for driving the extrusion ring 4 to move is installed in the middle of the U-shaped rod 1.

[0022] In this embodiment, a connecting portion 5 is provided between the extrusion rings 4, and the adjusting mechanism includes a screw 8, a bearing 6 and a handwheel 9. A mounting hole that penetrates the conductive rod 12 and the U-shaped rod 1 is provided in the middle of the conductive rod 12, and an insulating column 7 is installed in the mounting hole. A through hole is axially provided at the center of the insulating column 7, and the screw 8 is arranged in the through hole. The bearing 6 is embedded in one side surface of the connecting portion 5 and is arranged opposite to the through hole. The screw 8 is arranged in the through hole, one end of the screw 8 is installed in the inner ring of the bearing 6, and the other end is fixedly connected to the handwheel 9.

[0023] In this embodiment, a metal sleeve 13 is installed inside the through hole, and an internal thread is provided on the inner ring surface of the metal sleeve 13. The screw 8 is meshed and connected with the internal thread on the metal sleeve 13. The metal sleeve can ensure the firmness of the screw installation and avoid the screw being unable to rotate along the internal thread due to wear.

[0024] In this embodiment, the U-shaped rod 1 and the extrusion ring 4 are both made of insulating plastic material, and a ceramic layer is prefabricated inside the U-shaped rod 1. The insulating plastic and the internal ceramic layer can ensure the high temperature resistance of the device.

[0025] In this embodiment, the conductive rod 12, the conductive cylinder 11 and the pressing sheet 10 are all made of brass material, so that after the wires are connected, the conductive rod, the conductive cylinder and the pressing sheet can quickly conduct the wires to ensure conductivity.

[0026] In this embodiment, the inner ring surface of the extrusion ring 4 is arranged in contact with the outer ring surface of the U-shaped rod 1, so that the extrusion ring can only move axially along the outer wall surface of the U-shaped rod, thereby avoiding the extrusion ring from swinging.

[0027] When in use, the cores of the two wires can be inserted into the conductive cylinder respectively, and the hand wheel is rotated. The rotation of the hand wheel drives the screw rod, so that the screw rod moves along the internal thread on the metal sleeve toward one side of the conductive cylinder, and the movement of the screw rod pushes the connecting part and the extrusion ring, so that the extrusion ring can move forward along the U-shaped rod, and the guide part can be squeezed inward during the moving forward process. The movement of the guide part drives the pressing piece, and the pressing piece that is synchronously squeezed inward can lock and fix the two wires at one time. Conversely, after the hand wheel is rotated in the opposite direction, the extrusion ring can retreat, and after the extrusion ring is removed from the guide part, it can bounce outward due to the elasticity of the pressing piece itself. After the pressure from the pressing piece is lost, the wires can be directly taken out from the inside of the U-shaped rod, which is convenient for disassembly.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
