Description

Technical Field

[0001] The invention relates to the technical field of distribution network non-stop operation tools, and in particular to a composite compact live quick interface. Background Art

[0002] With the rapid development of urban construction, the requirements for power supply reliability are getting higher and higher. At present, the frequency of use of various operating vehicles such as box transformers and generators has greatly increased. When the low-voltage side of box transformers and generators is connected to the busbar at the user end, live quick connectors are often used.

[0003] However, during the use of the existing live quick interface, the current needs to be conducted in sequence through the paths of the copper busbar, the clamp arm, and the conductive rod. The clamp arm and the conductive rod are two different parts, and their connection increases a pair of contact resistances. The utility model patent with publication number CN210468226U records a busbar, including a first conductor and a second conductor; the first conductor is connected to the second conductor; the first conductor is connected to a fixed clamp seat; and a movable clamp seat is movably provided in the movable cavity. The copper busbar is clamped between the fixed contact piece and the movable contact piece, and the low-voltage cable is connected to the copper busbar at the user end through the connector, the second conductor, the first conductor, the fixed contact piece, and the movable contact piece. There is contact resistance between each conductive structure, and the contact resistance is much larger than the body resistance, which can easily lead to excessive resistance of the busbar, and then heat and burn. In addition, since the clamp arm is a necessary conductive structure, it is limited by the current carrying requirements. The material of the clamp arm is generally copper, aluminum, copper alloy or aluminum alloy. When its cross section meets the current carrying requirements and its strength meets the actual application, the size and thickness of the clamp arm need to be made very large to meet the current carrying requirements. This leads to the clamp head structure size being generally too large. However, due to the small spacing between the copper bars in the low-voltage cabinet, the live quick interface with an oversized clamp head structure does not meet the use requirements in most scenarios. Summary of the invention

Detailed implementation manners

[0020] For better explaining the present invention and facilitating understanding, the present invention will be described in detail below in conjunction with the drawings through specific implementation manners. Among them, the orientation nouns such as "upper", "lower", etc. mentioned in this article are referenced with the orientation of Figure 2 as a reference.

[0021] Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to be able to fully convey the scope of the present invention to those skilled in the art.

[0022] As Figure 1 and Figure 2As shown in the figure, the present invention provides a composite compact live fast interface, which includes a socket mechanism 1, a clamp mechanism 2, and a temperature measurement mechanism 3. Among them, the socket mechanism 1 includes an insulating housing 10 and a conductive rod 11 sleeved with the insulating housing 10. The conductive rod 11 is made of a metal material with a relatively small resistance, such as copper, aluminum, copper alloy, aluminum alloy, etc. The insulating housing 10 is a hollow structure with openings at both ends. The first end of the conductive rod 11 extends from the first end of the insulating housing 10 and is used to abut against the copper busbar 5 or the cable to conduct current. The clamp mechanism 2 includes a clamp arm 20, a sliding assembly 21, and a rotating shaft 22. The sliding assembly 21 is slidably connected to the first end of the conductive rod 11. The clamp arm 20 is connected to the sliding assembly 21. The clamp arm 20 is disposed opposite to the end face of the first end of the conductive rod 11. A downwardly open "U"-shaped clamping space 23 is formed between the clamp arm 20 and the conductive rod 11, which is convenient for clamping the clamping mechanism on the copper busbar 5 or the cable. Further, the rotating shaft 22 is coaxially arranged with the conductive rod 11 and is threadedly connected. The two can be connected by a sleeved structure. The sleeved form can be that the rotating shaft 22 is sleeved inside the conductive rod 11, or the rotating shaft 22 is sleeved outside the conductive rod 11. The rotating shaft 22 is rotatably connected to the sliding assembly 21. By using a special tool to rotate the rotating shaft 22, the rotational motion is converted into the axial movement of the rotating shaft 22 along the conductive rod 11 through the threaded connection between the rotating shaft 22 and the conductive rod 11. Then, the clamp arm 20 is driven by the rotating shaft 22 to move towards or away from the end face of the conductive rod 11.

[0023] As Figure 2As shown, driving the rotation of the rotating shaft 22 can drive the movement of the clamp arm 20. The copper busbar 5 or the cable is clamped by the end face of the clamp arm 20 and the first end of the conductive rod 11. The pressing of the contact point between the conductive rod 11 and the copper busbar 5 uses a positive pressure. Compared with the traditional method of pressing with a movable clamp slidably arranged on the conductive rod, the positive pressure is greater, ensuring the puncture of the insulating layer, and the fit between the conductive rod 11 and the copper busbar 5 is closer, effectively increasing the effective contact area between the conductive rod 11 and the copper busbar 5. After clamping, the copper busbar 5 and the conductive rod 11 form a conductive channel, and the clamp arm 20 does not participate in conduction. In actual use, the size of the clamp arm 20 can be set according to the spacing of the copper busbar 5, without considering the current-carrying requirements of the clamp arm 20, realizing the miniaturization and flattening of the clamp arm 20, and having a sufficiently small size of the moving part, which can be adapted to various narrow environments for installation and use, such as the scenario where the spacing of the copper busbar 5 in the cabinet is small. The conductive rod 11 is directly in contact with the copper busbar 5, avoiding the situation in the prior art where an additional pair of contact resistances is increased due to the connection between the clamp and the conductive rod when conducting electricity through the copper busbar, two clamps, and the conductive rod. The resistance value of the contact resistance is much larger than the resistance value of the bulk resistance. Reducing the contact resistance can effectively reduce the resistance of the conduction path. The contact resistance is inversely proportional to the positive pressure contact area. Increasing the positive pressure between the conductive rod 11 and the copper busbar 5 can effectively reduce the contact resistance, and further reduce the resistance of the conduction path. In addition, since the clamp arm 20 does not participate in conduction, it is not limited by the current-carrying requirements. The clamp arm 20 does not need to use materials with small resistance and large cross-sectional areas such as copper, aluminum, copper alloy, and aluminum alloy, reducing the volume and cost of the clamp arm 20. At the same time, the clamp arm 20 can use materials with higher rigidity, such as stainless steel materials, improving the strength and durability of the clamp arm 20.

[0024] Preferably, since the clamp arm 20 does not participate in conduction and there is no need to consider the conductivity of the clamp arm 20, the clamp arm 20 can be directly made of an insulating material; or it can be made of a non-insulating material, and all or part of the outer surface of the clamp arm 20 is coated with an insulating layer 201, as long as the strength meets the strength requirements for clamping the copper busbar 5 or the cable.

[0025] Furthermore, the material of the clamp arm 20 is a material with a yield strength greater than 180 MPa and good wear resistance, such as stainless steel, high-strength copper alloy, etc.; or a non-plastic material, such as cast iron, special ceramics, etc., to improve the strength of the clamp arm 20, thereby increasing the clamping force on the copper busbar 5 as much as possible, increasing the effective contact area between the conductive rod 11 and the copper busbar 5, and reducing the resistance value of the contact resistance between the conductive rod 11 and the copper busbar 5. The clamp arm 20 preferably uses stainless steel, because while having the above properties, it also has characteristics such as non-ferromagnetism, wear resistance, and corrosion resistance, ensuring sufficient strength to increase the clamping force on the copper busbar 5 while increasing the durability of the clamp arm 20, thereby effectively reducing the size of the clamp arm 20, achieving miniaturization and flattening of the clamp arm 20, and ensuring that the composite compact live fast interface has a small enough moving part size to be suitable for installation and use in various narrow environments, such as the scenario where the distance between the copper busbars 5 in the cabinet is small.

[0026] In the composite compact live fast interface of the present invention, the clamp arm 20 is driven to move by the sliding assembly 21 and the rotating shaft 22, so that relative sliding can occur between the clamp arm 20 and the conductive rod 11. The clamp arm 20 only serves as a support structure and does not participate in conduction. High-strength materials with poor conductivity or even conductive materials can be selected. At the same time, the clamp arm 20 is not limited by the current-carrying requirement, and the size of the clamp arm 20 can be effectively reduced, and the applicable scenarios are wider. In terms of conduction, conduction is carried out by directly abutting the copper busbar 5 and the conductive rod 11, reducing the number of contact resistances and having better conductivity. Moreover, by optimizing the conduction path and the size of the clamp arm 20, a lightweight and miniaturized structural design of the composite compact live fast interface is achieved, optimizing the length, volume, and weight of the product, facilitating carrying and use, and at the same time, avoiding the situation where the excessive self-weight causes the busbar in the low-voltage cabinet to deform during long-term clamping.

[0027] Such as Figure 3As shown, the sliding assembly 21 includes an outer sliding sleeve 211 and an inner slider 212. The conductive rod 11 has a hollow columnar structure with openings at both ends. The rotating shaft 22 is located inside the conductive rod 11. A part of the rod body of the rotating shaft 22 is threadedly connected to the inside of the conductive rod 11. When the rotating shaft 22 rotates, it moves axially along the conductive rod 11. A finger-proof cap 29 is provided at the second end of the rotating shaft 22. The outer sliding sleeve 211 is slidably sleeved on the conductive rod 11, and the clamp arm 20 is fixedly connected to the outer sliding sleeve 211. The length and shape of the outer sliding sleeve 211 can be set according to actual needs, and the present application does not limit the length and shape of the outer sliding sleeve 211. The inner slider 212 is slidably arranged inside the conductive rod 11. The outer sliding sleeve 211 and the inner slider 212 are coaxially arranged. The inner slider 212 is rotatably connected to the rotating shaft 22, and the inner slider 212 is driven to move axially along the conductive rod 11 by rotating the rotating shaft 22. A strip-shaped through hole arranged axially along the conductive rod 11 is formed on the conductive rod 11. The outer sliding sleeve 211 and the inner slider 212 are connected through the strip-shaped through hole. Specifically, the tail of the clamp arm 20 is rigidly connected to the outer sliding sleeve 211. The outer sliding sleeve 211 is a hollow tubular structure, and a first through-round hole penetrating the outer sliding sleeve 211 and perpendicular to the axis of the outer sliding sleeve 211 is formed thereon. The inner slider 212 is sleeved in the middle cavity of the conductive rod 11 and is close to the first end of the conductive rod 11. The inner slider 212 and the outer sliding sleeve 211 are coaxially arranged. A second through-round hole is formed at a position on the inner slider 212 corresponding to the first through-round hole on the outer sliding sleeve 211. The sliding assembly 21 further includes a linkage shaft 213. The linkage shaft 213 passes through the second through-round hole and then extends out from the strip-shaped through hole and connects the first through-round hole, connecting the inner slider 212 and the outer sliding sleeve 211 together. A stepped groove is provided on the right side of the inner slider 212. The first end of the rotating shaft 22 is sleeved in the stepped groove on the right side of the inner slider 212, and the rotating shaft 22 can rotate freely. When the rotating shaft 22 rotates, it moves axially along the conductive rod 11 and moves in the extending direction of the strip-shaped hole of the linkage shaft 213, thereby driving the outer sliding sleeve 211 to move.

[0028] As Figure 4 shown, the clamp mechanism 2 further includes a pre-tightening spring 24. The pre-tightening spring 24 is sleeved on the rotating shaft 22. One end of the pre-tightening spring 24 abuts against the inner slider 212, and the second end of the pre-tightening spring 24 abuts against the inner wall of the conductive rod 11. Specifically, the pre-tightening spring 24 is installed in the cavity formed between the right end face of the inner slider 212 and the left inner cylindrical hole of the conductive rod 11 to provide the pre-tightening force of the thread through the pre-tightening spring 24.

[0029] As Figure 6As shown in the figure, the conductive rod 11 includes a rod body and a piercing assembly 4. The rod body is the main conductive structure, made of materials with small resistance and large cross-sectional area such as copper, aluminum, copper alloy, and aluminum alloy. The rod body is sleeved with the insulating housing 10, and the first end of the rod body extends from the first end of the insulating housing 10. The sliding assembly 21 is slidably connected to the rod body, and the rotating shaft 22 is coaxially arranged and threadedly connected to the rod body. The piercing assembly 4 includes an expansion head 41 and a piercing blade 42. The expansion head 41 is sleeved on the first end of the rod body. Preferably, a second limiting groove 205 is formed on the end face of the first end of the rod body, and the expansion head 41 is detachably connected to the second limiting groove 205. An installation groove 43 is formed on the end face of the expansion head 41 facing the limiting arm 202, and part of the piercing blade 42 is arranged in the installation groove 43. Specifically, the expansion head 41 is made of materials with small resistance such as copper, aluminum, copper alloy, and aluminum alloy. It is sleeved and installed at the left end of the rod body and connected to the second limiting groove 205. It is provided with a light hole, and the set screw passes through the light hole and is tightened in the threaded hole on the rod body. An installation groove 43 is formed on the left end face of the expansion head 41, and the piercing blade 42 is connected to the installation groove 43. Part of the blade extends out of the installation groove 43. When vertically clamping the copper row 5, the piercing blade 42 abuts against the copper row 5, and at the same time, the left end face of the expansion head 41 also abuts against the copper row 5. The copper row 5 or the cable is clamped by the clamping arm 20 and the end face of the first end of the piercing assembly 4. The pressing of the contact point between the conductive rod 11 and the copper row 5 adopts a positive pressure to ensure piercing the insulating layer and reducing the contact resistance. The modular expansion of the conductive rod 11 further realizes the coverage of multi-scenario applications.

[0030] See Figure 3 , the clamping arm 20 includes a limiting arm 202 and a connecting arm 203. The limiting arm 202, the connecting arm 203, and the sliding assembly 21 are connected in sequence. The limiting arm 202 is arranged opposite to the end face of the first end of the conductive rod 11. A first limiting groove 204 is formed on the limiting arm 202, and the notch of the first limiting groove 204 is arranged opposite to the notch of the second limiting groove 205. See Figure 5 , the first limiting groove 204 can cooperate with the second limiting groove 205 on the end face of the rod body after removing the piercing assembly 4. The first limiting groove 204 and the second limiting groove 205 clamp the side of the copper row 5 to limit the copper row 5 when horizontally clamping the copper row 5, improving the clamping stability; in addition, the overhead cable can also be clamped through the first limiting groove 204 and the second limiting groove 205, improving the flexibility of the equipment use and realizing the coverage of multi-scenario applications.

[0031] As Figure 4As shown, the socket mechanism 1 further includes a stop block 25 and a tapered ring 26. The stop block 25 is detachably connected to the middle part of the conductive rod 11. The tapered ring 26 is connected to the stop block 25, and the insulating housing 10 is sleeved on the stop block 25. A limiting protrusion 101 is provided on the inner wall of the insulating housing 10, and the limiting protrusion 101 abuts between the stop block 25 and the tapered ring 26. Specifically, the tapered ring 26 is designed as an open cone and is sleeved on the small end of the stop block 25. A plurality of light holes are evenly formed in the stop block 25 along the axial direction of the stop block 25. The stop block 25 is sleeved on the conductive rod 11, and threaded holes are provided at positions corresponding to the light holes on the stop block 25 of the conductive rod 11. The stop block 25 and the conductive rod 11 are connected together by set screws. The insulating housing 10 is sleeved on the stop block 25, and the limiting protrusion 101 on the inner wall of the insulating housing 10 is clamped and fixed by the tapered ring 26 and the stop block 25, so as to realize the axial fixation of the insulation. In addition, a step surface is provided on the outer cylindrical surface of the conductive rod 11, a gasket 27 abuts on the step surface, a cavity is formed between the gasket 27 and the stop block 25, and a compression spring 28 is installed in the cavity.

[0032] As Figure 4 shown, the socket mechanism 1 further includes an interface component 12. The interface component 12 is arranged at the second end of the insulating housing 10, and the interface component 12 is connected to the second end of the conductive rod 11. Further, the interface component 12 includes a leaf spring 121 and an insulating cap 122. A jack is formed at the second end of the conductive rod 11. The leaf spring 121 is arranged in the jack, and the insulating cap 122 is arranged on the end surface of the second end of the conductive rod 11. The power generation vehicle plug is inserted into the jack and abuts against the leaf spring 121, and the leaf spring 121 is used to lock the power generation vehicle plug once to prevent the power generation vehicle plug from loosening.

[0033] As Figure 4 and Figure 8 shown, the socket mechanism 1 further includes a secondary locking component 13. The secondary locking component 13 is arranged at the second end of the insulating housing 10, and the secondary locking component 13 can lock the power generation vehicle plug connected to the conductive rod 11. Further, the secondary locking component 13 includes a locking member 131 and a return spring 132. Two through holes and a positioning blind hole are provided near the second end of the insulating housing 10. The elastic arm of the locking member 131 passes through the through holes on the insulating housing 10, and an inverted buckle is provided on the elastic arm, so that the locking member 131 is connected to the insulating housing 10. A positioning boss is provided on the inner side of the top of the locking member 131. One end of the return spring 132 is connected to the positioning boss, and the other end extends into the positioning blind hole of the insulating housing 10. After the power generation vehicle plug is inserted into the jack, the housing of the power generation vehicle plug is clamped between the two inverted buckles, and the power generation vehicle plug is locked secondly to form a double redundant protection to ensure safe and efficient use.

[0034] As Figure 1As shown in the figure, the composite compact live fast interface further includes a temperature measuring mechanism 3. The temperature measuring mechanism 3 is arranged on the insulating housing 10 and connected to the conductive rod 11. The temperature measuring mechanism 3 is preferably a passive temperature sensor. There is a stepped hole on the left side of the insulating housing 10. The passive temperature sensor is installed in the stepped hole on the insulating housing 10. The temperature measuring probe passes through the stepped hole and abuts against the corresponding temperature measuring hole in the conductive rod 11, so as to detect and display the temperature on the conductive rod 11 in real time, which is convenient for users to directly observe the temperature of the conductive rod 11 and reduces the risk of high temperature of the conductive rod 11 caused by poor contact.

[0035] In the composite compact live fast interface of the present invention, the clamping arm 20 is driven to move through the sliding assembly 21 and the rotating shaft 22, so that the clamping arm 20 and the conductive rod 11 can slide relative to each other. The clamping arm 20 is only used for support, and a material with poor conductivity but good strength can be selected. At the same time, the size of the clamping arm 20 can be made smaller, and the applicable scenarios are wider. Conductively, the direct contact conduction method between the copper busbar 5 and the conductive rod 11 reduces the number of contact resistances and has better conductivity. Moreover, by optimizing the conduction path and the size of the clamping arm 20, the lightweight and miniaturized structural design of the composite compact live fast interface is realized, optimizing the length, volume and weight of the product, which is convenient for carrying and using. At the same time, it avoids the situation that the busbar is deformed due to excessive self-weight when clamping the busbar in the low-voltage cabinet for a long time.
