[0002] Flexible graphite wire, as a high-performance sealing material, has been widely used in industrial fields, especially in high-temperature and high-pressure environments. It possesses excellent heat resistance and chemical stability, effectively preventing media leakage and ensuring the safe operation of equipment. The length of a single flexible graphite wire is limited; in some cases, longer flexible graphite wires are required, necessitating the connection of multiple flexible graphite wires end-to-end.

[0003] Currently, the following methods are commonly used to achieve effective connection between flexible graphite wires: one is the direct binding method, which involves fixing the flexible graphite wire to the equipment interface using ropes or straps; the other is the adhesive method, which uses glue or other adhesives to bond the flexible graphite wire to the equipment interface.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] according to Figure 1-5 This utility model provides a flexible graphite wire connection structure, including: a terminal block 1, a plug plate 2, and a fixing rod 3.

[0023] The terminal block 1 has a wiring groove 11. The insert plate 2 can extend into the wiring groove 11. The terminal block 1 also includes a base plate 12, side plates 13, and a top plate 14. The two side plates 13 are located on both sides of the base plate 12. The top plate 14 is located on the side of the side plates 13 away from the base plate 12. The top plate 14 has an observation opening 141. The width of the observation opening 141 is smaller than the width of the insert plate 2.

[0024] When two flexible graphite wires need to be connected, one end of one graphite wire is inserted into the wiring groove 11 and placed on the base plate 12. Then, one end of the other graphite wire is inserted into the wiring groove 11, so that the ends of the two graphite wires are in contact. Then, the insert plate 2 is inserted into the wiring groove 11 with one side against the graphite wire. When the insert plate 2 is inserted into the wiring groove 11, it will abut against the top plate 14 of the terminal block 1, so that friction is generated between the two. Then, the insert plate 2 is inserted further until it is fully inserted into the terminal block 1. At this time, one end of the insert plate 2 abuts against the top plate 14, and the other end abuts against the graphite wire, so that the graphite wire abuts against the base plate 12. That is, the two flexible graphite wires are clamped in the terminal block 1 by the insert plate 2 and the terminal block 1. This method is more stable and reliable than the binding and adhesive bonding methods, and is not easily affected by factors such as temperature and humidity, so it has a longer service life. An observation opening 141 is provided on the top plate 14 so that the graphite wire can be better observed when it is inserted into the wiring groove 11. Without the observation opening 141, it would be very inconvenient to view from the side.

[0025] The terminal block 1 also includes a baffle 15. The baffle 15 is located on the side of the top plate 14 near the observation port 141. The baffle 15 is located at the end of the top plate 14. A limiting groove 142 is formed on the side of the top plate 14 near the bottom plate 12. A limiting block 21 is provided on one side of the insertion plate 2. The limiting block 21 corresponds to the limiting groove 142. The limiting block 21 can slide within the limiting groove 142.

[0026] When inserting the plug plate 2 into the wiring groove 11 to fix the two graphite wires together, the plug plate 2 needs to be fully inserted into the wiring groove 11. However, if the force is not applied properly, the plug plate 2 may protrude part of the wiring groove 11. This utility model is equipped with a baffle 15, which allows the plug plate 2 to be inserted directly. When the plug plate 2 touches the baffle 15, it indicates that the plug plate 2 has reached the appropriate position, making it more convenient to use. When inserting the plug plate 2 into the wiring groove 11, if the plug plate 2 is in close contact with the side plate 13, it will cause greater friction between the two, resulting in faster wear of this utility model. If the plug plate 2 is not in close contact with the side plate 13, but has a certain gap with it, the plug plate 2 will shift during insertion, and after insertion, the plug plate 2 may wobble or shift, reducing stability. This invention features a limiting groove 142 on the top plate 14 near the bottom plate 12, and a limiting block 21 on the side of the insert plate 2. When the insert plate 2 is inserted, the limiting block 21 can be inserted into the limiting groove 142, thus limiting the limiting block 21 and preventing it from shifting. This prevents the limiting block 21 from shaking. Furthermore, the small contact area between the limiting block 21 and the limiting groove 142 results in less friction and makes it less prone to damage. This ensures that the insert plate 2 is more stable and less susceptible to damage when fixing the graphite wire.

[0027] The terminal block 1 also includes: a positioning rod 16. The two ends of the positioning rod 16 are connected to two side plates 13 respectively. One side of the base plate 12 is fitted onto the positioning rod 16. The base plate 12 is rotatable relative to the positioning rod 16. A fixing rod 3 passes through one side plate 13 and extends into the other side plate 13. The fixing rod 3 is movable relative to the side plate 13. A fixing opening 121 is provided on the side of the insert plate 2 away from the positioning rod 16. The fixing rod 3 passes through the fixing opening 121. The fixing rod 3 is movable within the fixing opening 121. The fixing rod 3 includes: abutment blocks 31. Two abutment blocks 31 are disposed on both sides of the fixing rod 3. A circular hole 131 is provided in the side plate 13 into which the fixing rod 3 extends. The circular hole 131 corresponds to the abutment block 31. The abutment block 31 is rotatable relative to the side plate 13. The fixing rod 3 also includes: a control rod 32. The control rod 32 is disposed on the side of the fixing rod 3 away from the abutment block 31. The control rod 32 is L-shaped. One side of the control lever 32 is perpendicular to the line connecting the two abutment blocks 31.

[0028] Although this invention can securely fix the flexible graphite wires, the insertion plate 2 is fully inserted into the wiring slot 11, making it difficult to release the two graphite wires. To address this, one side of the base plate 12 is fitted onto the positioning rod 16 of the wiring seat 1, allowing the base plate 12 to rotate around the positioning rod 16. Simultaneously, the other side of the base plate 12 is penetrated by a fixing rod 3, which passes through one side plate 13 and extends into the other side plate 13. This fixing rod 3 secures the base plate 12 to the side plate 13, ensuring the base plate 12 remains fixed when two graphite wires are secured. When repair or other operations are required to separate the two graphite wires, the fixing rod 3 can be pulled out. The base plate 12 can rotate around the positioning rod 16, and one side of the base plate 12 can be rotated away from the graphite line. At this time, the contact area between the graphite line and the base plate 12 is greatly reduced, that is, the friction is reduced, and the graphite line can be moved closer to the base plate 12, which reduces the contact area and friction between the graphite line and the insert plate 2. At this time, there is no graphite line blocking one side of the insert plate 2, and then the insert plate 2 can be pulled out. Since the limiting block 21 of the insert plate 2 extends into the limiting groove 142, the insert plate 2 may not fall off immediately and needs to be pulled out manually. Since the top plate of this utility model has an observation port 141, the insert plate 2 can be pinched and pulled out from the observation port 141 and the side of the insert plate 2 away from the observation port 141, respectively. This is less strenuous than pressing the insert plate 2 from the bottom and pulling it out by friction. When the base plate 12 and the side plate 13 are fixed by the fixing rod 3, the fixing rod 3 may fall off. The fixing rod 3 of this utility model is provided with an abutment block 31. After the fixing rod 3 is inserted to fix the base plate 12 and the side plate 13, the abutment block 31 matches its insertion port. At this time, the fixing rod 3 can be rotated, so that the abutment block 31 rotates with it, so that the abutment block 31 does not match the insertion port, so that the abutment block 31 is limited, so that the abutment block 31 is stuck in the round hole 131 by the wall of the round hole 131, making it difficult to rotate without force, and even more difficult to fall off, so as to ensure the stability of the above structure. The L-shaped rod of the fixing rod 3 makes it easier to apply force during rotation. Because the width of the fixing rod 3 is increased by the abutment block 31, the line connecting the two abutment blocks 31 is horizontal when they are inserted. This prevents the abutment block 31 from increasing the height of the fixing rod 3 and causing it to protrude from the base plate. The control rod 32 rotates after the abutment block 31 is inserted into the circular hole 131. If one side of the control rod 32 is parallel to the line connecting the two abutment blocks 31, the control rod 32 may come into contact with the ground or be suspended in the air when the abutment blocks 31 rotate. This makes it easy for the abutment blocks 31 to be pulled to a near-horizontal state by their own weight, causing the fixing rod 3 to easily detach. This invention, by having one side of the control rod 32 perpendicular to the line connecting the two abutment blocks 31, ensures that after the abutment blocks 31 rotate a certain distance, the difference from a horizontal state is significant, and the control rod 32 rests on the ground, reducing the impact of force and ensuring stability.

[0029] Working principle and usage process of this utility model:

[0030] When it is necessary to connect two flexible graphite wires, one end of one graphite wire is inserted into the wiring groove 11 and placed on the base plate 12. Then, one end of the other graphite wire is inserted into the wiring groove 11 so that the ends of the two graphite wires are in contact. Then, one side of the insert plate 2 is attached to the graphite wire, and the limiting block 21 on the other side is inserted into the limiting groove 142 so that the insert plate 2 is inserted into the wiring groove 11. Then, the insert plate 2 is inserted further so that it abuts against the baffle 15 and is fully inserted into the terminal block 1. At this time, one end of the insert plate 2 abuts against the top plate 14 and the other end abuts against the graphite wire, so that the graphite wire abuts against the base plate 12, so that the two flexible graphite wires are clamped in the terminal block 1. When it is necessary to release the two graphite lines, rotate the control lever 32 so that the line connecting the two contact blocks 31 becomes horizontal. Then pull the fixing lever 3 to separate the fixing lever 3 from the base plate 12 and the side plate 13. Then rotate one side of the base plate 12 away from the top plate 14 and move the graphite line at that point closer to the base plate 12. This reduces the contact area and friction between the graphite line and the insert plate 2. At this time, there is no graphite line blocking one side of the insert plate 2. Then, the insert plate 2 can be pinched and pulled out from the observation port 141 and the side of the insert plate 2 away from the observation port 141, respectively, so that the two graphite lines are released from the fixation.

[0031] In summary, this utility model clamps the graphite wire using a connector and a plug plate, which is more stable and reliable than binding and adhesive bonding methods. It is also less affected by factors such as temperature and humidity, and has a longer service life.
