Description

Technical Field

[0001] This utility model relates to the field of silicon core furnace technology, and in particular to a connecting component for use inside a round silicon core furnace. Background Technology

[0002] The flexible connector inside the round silicon core furnace rotates in the inner ring forward and the outer ring in the opposite direction. Currently, the winding direction of the flexible connector wire rope is consistent with the inner ring rotation direction of the silicon core furnace seed crystal disk. When the silicon core gets stuck, the wire rope will not become loose because it rotates in the same direction as the silicon core. However, once the outer ring gets stuck, the wire rope will rotate in the opposite direction to the silicon core, and the wire rope will inevitably become loose, causing the flexible connector to malfunction.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the present invention provides a connecting assembly for use inside a circular silicon core furnace, including: a steel wire connecting rod 1, a hanger 2, a connector 3, a positioning nut 4, and a protective sleeve 5. The hanger 2 is installed at one end of the steel wire connecting rod 1 and is hooked to the seed crystal plate of the circular silicon core furnace. The connector 3 is sleeved on the other end of the steel wire connecting rod 1, and a thread 31 is provided on the outer wall of the connector 3. A graphite chuck inside the circular silicon core furnace is connected to the thread 31 of the connector 3. The positioning nut 4 is installed on the outside of the connector 3. The protective sleeve 5 is sleeved on the steel wire connecting rod 1 and located between the hanger 2 and the connector 3.

[0036] The hanger 2, protective sleeve 5, and connector 3 are sequentially installed on the wire connecting rod 1. Then, the positioning nut 4 is installed on the connector 3. In use, the hanger 2 is attached to the seed crystal plate of the circular silicon core furnace, and then the connector 3 is connected to the graphite chuck thread 31 of the circular silicon core furnace. During use, the high temperature inside the circular silicon core furnace can damage the wire connecting rod 1; therefore, a protective sleeve 5 is installed on the wire connecting rod 1 between the hanger 2 and the connector 3.

[0037] Because the inner and outer rings of the circular silicon core furnace rotate in different directions, the wire connecting rod 1 is formed by forward and reverse winding of the wire rope.

[0038] To prevent the wire rope of the wire connecting rod 1 from becoming loose or breaking at high temperatures, a protective sleeve 5 is installed on the outside of the wire connecting rod 1.

[0039] To distinguish between the wire connecting rod 1 formed by forward winding and reverse winding, a marking element 41 is provided on the positioning nut 4.

[0040] It should be noted that the outer ring of the circular silicon core furnace uses a reverse-wound steel wire connecting rod 1, while the inner ring uses a forward-wound steel wire connecting rod 1.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, to facilitate fixing the positioning element 11 to the wire connecting rod 1, positioning elements 11 are provided at both ends of the wire connecting rod 1. The middle part of the hook 2 is provided with a mounting through hole 21 that matches the wire connecting rod 1. To prevent the positioning element 11 from falling off during use, the size of the positioning element 11 is larger than the size of the mounting through hole 21.

[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the mounting component 2 includes a straight cylindrical portion 22 and a positioning portion 23. The inner diameter of the straight cylindrical portion 22 matches the steel wire connecting rod 1. The positioning portion 23 is disposed at one end of the straight cylindrical portion 22 and matches the positioning groove on the seed crystal disk of the circular silicon core furnace.

[0043] To simplify the structure of the mounting component 2, it is configured as a straight cylindrical part 22 and a positioning part 23. The positioning part 23 is larger than the straight cylindrical part 22, which facilitates the mounting of the positioning part 23 onto the seed crystal tray of the circular silicon core furnace.

[0044] In one embodiment, in order to facilitate the rotation of the connector 3 during use, the connector 3 and the wire connecting rod 1 are fitted with a clearance.

[0045] In one embodiment, the protective sleeve 5 is a flexible protective sleeve 5, which is designed to facilitate the fitting of the protective sleeve 5 onto the wire connecting rod 1.

[0046] In one embodiment, in order to improve the heat insulation performance of the protective sleeve 5, the protective sleeve 5 is a high-temperature resistant PTFE protective sleeve 5.

[0047] In one embodiment, such as Figure 1 As shown, in order to improve the service life of the wire connecting rod 1, the length of the protective sleeve 5 is matched with the distance between the connector 3 and the hanging part 2.

[0048] In one embodiment, to facilitate the fitting of the protective sleeve 5 onto the wire connecting rod 1, the protective sleeve 5 and the wire connecting rod 1 are fitted with a clearance.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
