Description

[0001] This invention claims priority to Chinese Patent Application No. 202210266566.3, filed on March 17, 2022, entitled "Busbar Plug-in Structure, Busbar Trunking, Plug-in Connector and Locking Structure", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of electrical technology, and in particular to connectors and power distribution systems. Background Technology

[0003] A power distribution system typically includes multiple busbars, with adjacent busbars connected by connectors to extend the path of the transmission lines.

[0004] In related technologies, the connector includes pressure plates and gaskets located on both sides. The gaskets are inserted into slots opened in the pressure plates, and fixing bolts pass through the main body of the connector and are connected to the gaskets, so that the main body of the connector is clamped between the two pressure plates.

[0005] However, the design of the aforementioned pressure plate and gasket not only complicates the structure of the pressure plate, but also makes it easy for the gasket to be lost when the connector is disassembled. Summary of the Invention

[0006] In view of this, the present invention provides a connector and a power distribution system that can solve the above-mentioned technical problems.

[0007] Specifically, the following technical solutions are included:

[0008] On one hand, a connector is provided, the connector comprising a plurality of crimping guides, a plurality of insulating baffles, two pressure plates and fixing bolts;

[0009] The plurality of crimping guide plates, the plurality of insulating baffles, and the two pressure plates each have mounting holes for the fixing bolts to pass through. The plurality of crimping guide plates, the plurality of insulating baffles, and the two pressure plates are stacked and arranged and insulatedly connected by the fixing bolts.

[0010] One surface of the crimping guide plate is in contact with the surface of the insulating baffle, and the other surface is used to contact the conductive plate of the busbar trunking. The two crimping plates are located on the outermost sides.

[0011] The pressure plate includes a middle plate segment and a first side plate segment and a second side plate segment located on both sides of the middle plate segment. The inner surface of the middle plate segment has a concave structure, and the mounting holes of the pressure plate are provided in the middle plate segment.

[0012] In some possible implementations, the inner surfaces of the first side plate segment and the second side plate segment are both planar structures, and the two planar structures are located on opposite sides of the concave structure.

[0013] In some possible implementations, the outer surfaces of the first side plate segment and the second side plate segment are arranged at an angle;

[0014] From the free end of the side plate segment to the end where it connects to the middle plate segment, the thickness of the first side plate segment and the second side plate segment gradually increases.

[0015] The thickness of the intermediate plate segment is greater than or equal to the maximum thickness of the first side plate segment and the second side plate segment.

[0016] In some possible implementations, both the first side plate segment and the second side plate segment are arc-shaped plates.

[0017] In some possible implementations, the connector further includes a plurality of insulated flexible supports located between two adjacent crimping guides to form a predetermined spacing between the two crimping guides.

[0018] In some possible implementations, the flexible support is fitted over the outside of the fixing bolt.

[0019] In some possible implementations, the insulating baffle is provided with a first end protrusion and a second end protrusion at both ends;

[0020] One of the first end protrusion and the second end protrusion includes a first abutting surface and a second abutting surface;

[0021] The first abutting surface is used to abut against the corresponding end of the crimping guide plate;

[0022] The second abutting surface is used to abut against the corresponding conductive plate of the busbar trough.

[0023] In some possible implementations, the insulating baffle is provided with a first end protrusion and a second end protrusion at both ends; the protrusion of the upper end protrusion is longer.

[0024] In some possible implementations, one of the two pressure plates has an internal thread in its mounting hole;

[0025] The fixing bolt and the pressure plate with internal threads are threaded together.

[0026] In some possible implementations, the two pressure plates abut against the two outermost insulating baffles of the plurality of insulating baffles, respectively.

[0027] In some possible implementations, the connector also includes multiple temperature sensors and multiple indicating components;

[0028] Each of the temperature sensors is in contact with one of the crimping guide plates, and each indicating component is electrically connected to one of the temperature sensors;

[0029] The indicator component is configured to indicate a temperature anomaly when it detects that the temperature sent by the corresponding temperature sensor exceeds a temperature threshold.

[0030] On the other hand, a power distribution system is provided, the power distribution system including any of the connectors described above and a plurality of busbars, the connector being connected between two adjacent busbars.

[0031] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0032] The connector provided in this embodiment of the invention uses two integrally structured pressure plates to clamp the main body of the connector. The inner surface of the middle section of the pressure plates is concave, and the mounting holes of the pressure plates are located in the middle section. The concave structure of the middle section provides the pressure plates with a certain degree of elastic deformation, which helps to reduce the stress generated when tightening the fixing bolts. Therefore, the pressure plates with the arc-shaped middle section ensure that the fixing bolts are effectively tightened, so that the crimping guide plate of the connector and the conductive plate of the busbar groove fit tightly together, resulting in good conductivity between them.

[0033] The pressure plate provided in this embodiment of the invention is an integrated structural design. Through ingenious structural improvements, it combines the functions of a baffle and a gasket in related technologies, and additionally has the advantages of simple structure, low cost, convenient operation, reliability and high efficiency.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0063] In the description of the embodiments of the present invention, the terms "thickness", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure.

[0064] The power distribution system includes multiple busbar trunking, multiple connectors, and multiple plug-in boxes. Two busbar trunkings are connected by connectors, which allows the busbar trunking to be laid along a set track for hundreds of meters or even longer to extend the power transmission path. The plug-in boxes can be plugged into the busbar trunking to draw power from it.

[0065] An exemplary application scenario for a power distribution system could be an Internet Data Center (IDC). Multiple busbars are connected by multiple connectors and arranged in the IDC's server room. External power (such as mains power and batteries) is introduced into the IDC server room and connected to one of the busbars. The plug-in box is plugged into the busbar to draw power and supply power to the various server racks (such as the rack cabinets) in the IDC server room.

[0066] In related technologies, the connector includes pressure plates and gaskets located on both sides. The gaskets are inserted into slots opened in the pressure plates, and fixing bolts pass through the main body of the connector and are connected to the gaskets, so that the main body of the connector is clamped between the two pressure plates.

[0067] However, the design of the aforementioned pressure plate and gasket not only complicates the structure of the pressure plate, but also makes it easy for the gasket to be lost when the connector is disassembled.

[0068] To address the aforementioned technical problems, embodiments of the present invention provide a connector 100, as shown in the attached figure. Figure 3 -Appendix Figure 5 As shown, the connector 100 includes multiple crimping guides 1, multiple insulating baffles 2, two pressure plates 3, and fixing bolts 4.

[0069] Multiple crimping guides 1, multiple insulating baffles 2 and two pressure plates 3 each have mounting holes for fixing bolts 4 to pass through. The multiple crimping guides 1, multiple insulating baffles 2 and two pressure plates 3 are stacked and arranged and insulatedly connected by fixing bolts 4.

[0070] Further integration Figure 1 and Figure 2 It can be seen that one surface of the crimping guide plate 1 is in contact with the surface of the insulating baffle 2, and the other surface is used to contact the conductive plate 2001 of the busbar 200. The two pressure plates 3 are located on the outermost side respectively.

[0071] As attached Figure 6 As shown, the pressure plate 3 includes a middle plate segment 31 and a first side plate segment 32 and a second side plate segment 33 located on both sides of the middle plate segment 31. The inner surface of the middle plate segment 31 is a concave structure 301, and the mounting holes of the pressure plate 3 are provided in the middle plate segment 31. The inner surface of the middle plate segment 31 refers to its surface facing the insulating baffle 2.

[0072] For example, the mounting hole of the pressure plate 3 coincides with the central axis of the intermediate plate segment 31, that is, the mounting hole of the pressure plate 3 is located in the middle of the intermediate plate segment 31.

[0073] The connector 100 provided in this embodiment of the invention uses two integrally structured pressure plates 3 to clamp the main body of the connector 100. The inner surface of the middle plate segment 31 of the pressure plate 3 is a concave structure 301, and the mounting hole of the pressure plate 3 is located in the middle plate segment 31. The concave structure of the middle plate segment 31 provides the pressure plate 3 with a certain elastic deformation capacity, which helps to reduce the stress generated when the fixing bolt 4 is tightened. It can be seen that the pressure plate 3 with the arc-shaped middle plate segment 31 can ensure that the fixing bolt 4 is effectively tightened, so that the crimping guide plate 1 of the connector 100 and the conductive plate 2001 of the busbar 200 are tightly fitted, resulting in good conductivity between them.

[0074] The pressure plate 3 provided in this embodiment of the invention is an integrated structure design. Through ingenious structural improvements, it combines the functions of a baffle and a gasket in related technologies, and additionally has the advantages of simple structure, low cost, convenient operation, reliability and high efficiency.

[0075] The pressure plate 3 is generally made of metal and is conductive. In order to prevent users from getting electric shock when touching the pressure plate 3 during installation, in this connector 100, the contact with the pressure plate 3 can be an insulating baffle 2 or a ground conductive plate 20010 of the busbar 200.

[0076] To facilitate the description of how the pressure plate 3 operates, the following example illustrates the contact between the pressure plate 3 and the insulating baffle 2:

[0077] See in some examples Figure 6 and Figure 8 The inner surfaces of the first side plate segment 32 and the second side plate segment 33 are both planar structures 302, and the two planar structures 302 are located on opposite sides of the concave structure 301.

[0078] To give a further example, the first side plate segment 32 and the second side plate segment 33 of the pressure plate 3 are both flat plates, and the first side plate segment 32 and the second side plate segment 33 are in contact with the insulating baffle 2 through their respective planar structures 302 (to... Figure 3 For example, the planar structure 302 is parallel to the vertical direction.

[0079] In this way, the contact between the side plate section of the pressure plate 3 and the insulating baffle 2 is a planar contact. This planar contact can increase the contact area between the first side plate section 32 and the second side plate section 33 and the insulating baffle 2, and avoid the pressure of the side plate section on the insulating baffle 2 being too concentrated.

[0080] When the surfaces of the first side plate segment 32 and the second side plate segment 33 that contact the insulating baffle 2 are planar, the first side plate segment 32 and the second side plate segment 33 can be plate segments with the same thickness or plate segments with a gradient distribution of thickness. Regardless of which method is chosen, the above-mentioned effect can be achieved. Here, the direction of the thickness is consistent with the axial direction of the fixing bolt 4.

[0081] In some examples, the first side plate segment 32 and the second side plate segment 33 are plate segments with a gradient thickness distribution, as shown in the attached figure. Figure 6 As shown, the outer surfaces of the first side plate segment 32 and the second side plate segment 33 are arranged at an angle; from the free end of the side plate segment to the end where it is connected to the middle plate segment 31, the thickness of the first side plate segment 32 and the second side plate segment 33 gradually increases; the thickness of the middle plate segment 31 is greater than or equal to the maximum thickness of the first side plate segment 32 and the second side plate segment 33.

[0082] In this example, the middle section 31 of the pressure plate 3 is bowl-shaped or near-bowl-shaped, with planar structures on both sides, and the thickness of the pressure plate 3 gradually decreases from the middle section 31 to the side sections. This makes the pressure plate 3 more prone to elastic deformation during the tightening of the fixing bolts 4, thus achieving the purpose of optimizing the above-mentioned effects.

[0083] In other examples, such as the appendix Figure 8 As shown, both the first side plate segment 32 and the second side plate segment 33 are arc-shaped plates, and both the first side plate segment 32 and the second side plate segment 33 smoothly transition with the middle plate segment 31, so that the pressure plate 3 forms an integral arc-shaped structure with a smooth transition.

[0084] For example, the pressure plate 3 is an integral and deformable metal arc plate, and the mounting hole of the pressure plate 3 is located at the center of the arc plate. The two pressure plates 3 are arranged in a bracket shape on the outermost layer. In this way, when the fixing bolt 4 is tightened, the pressure plate 3 can be deformed from the arc plate to the flat plate, so that the crimping guide plate 1 of the connector 100 and the conductive plate 2001 of the busbar 200 are tightly attached.

[0085] As mentioned above, multiple crimping guides 1, multiple insulating baffles 2, and two pressure plates 3 are stacked and connected insulatedly by fixing bolts 4. The crimping guides 1 overlap the insulating baffles 2. The arrangement of the insulating baffles 2 and the crimping guides 1 can be found below:

[0086] If the busbar trunking 200 includes the ground electrode conductive plate 20010, then see... Figure 5 Among the multiple insulating baffles 2, the outermost insulating baffle 2 abuts against a pressure plate 3 on the corresponding side, while the outer surface of the other outermost insulating baffle 2 is fixed with a crimping guide plate 1 for contacting the ground electrode conductive plate 20010. The crimping guide plate 1 and the pressure plate 3 on the corresponding side are adjacent and there is a gap between them for the ground electrode conductive plate 20010 to be inserted.

[0087] Of course, in the scheme where the busbar 200 includes the ground electrode conductive plate 20010, the two pressure plates 3 can also abut against the two outermost insulating baffles 2 of the plurality of insulating baffles 2 respectively. That is, among the plurality of insulating baffles 2, one outermost insulating baffle 2 is in contact with one pressure plate 3 on the corresponding side, and the other outermost insulating baffle 2 is in contact with another pressure plate 3 on the corresponding side.

[0088] If the ground electrode conductive plate 2001 is not included among the multiple conductive plates 2001 of the busbar 200, then, among the multiple insulating baffles 2, one outermost insulating baffle 2 abuts against one pressure plate 3 on the corresponding side, and another outermost insulating baffle 2 abuts against another pressure plate 3 on the corresponding side.

[0089] In some examples, both sides of the insulating baffle 2 that do not contact the pressure plate 3 can be connected to crimping guides 1 to ensure the conductivity stability of the connector 100 and the busbar 200. The insulating baffle 2 that contacts the pressure plate 3 has crimping guides 1 connected to the side of its surface away from the pressure plate 3 to prevent the pressure plate 3 from becoming energized.

[0090] For ease of description, we can Figure 5 The direction along the length of the fixing bolt 4 is designated as left and right, with the nut of the fixing bolt 4 as the right end and the other end as the left end. The insulating baffles 2 from left to right are designated as the first insulating baffle 2, the second insulating baffle 2, the third insulating baffle 2, the fourth insulating baffle 2, and the fifth insulating baffle 2.

[0091] like Figure 5 As shown, there is a gap between the crimping guide 1 located to the right of the first insulating baffle 2 and the crimping guide 1 located to the left of the second insulating baffle 2, a gap between the crimping guide 1 located to the right of the second insulating baffle 2 and the crimping guide 1 located to the left of the third insulating baffle 2, and so on. There is also a gap between the crimping guide 1 located to the right of the fifth insulating baffle 2 and the right pressure plate 3. All of the above gaps are used for the insertion of the conductive plate 2001 of the busbar trough 200.

[0092] like Figure 1 and Figure 2 As shown, the portions of each conductive plate 2001 of a busbar 200 that extend beyond the end cap are respectively inserted into the aforementioned spacing and located on one side of the fixing bolt 4 (e.g., Figure 2 On the left side), the portions of each conductive plate 2001 of another busbar 200 extending from the end cap are respectively inserted into the aforementioned spacing and located on the other side of the fixing bolt 4 (e.g., on the left side). Figure 2 (Right side). After the fixing bolt 4 is tightened, the busbar grooves 200 on both sides of the fixing bolt 4 are in close contact with the crimping guide plate 1 of the connector 100 and thus conduction is achieved, thereby realizing the conduction of the two busbar grooves 200.

[0093] In related technologies, the crimping guide plate has an arc-shaped protrusion in the middle, creating a gap between two opposing crimping guide plates to allow the insertion of the busbar's conductive plate. However, before the busbar's conductive plate is inserted, the protrusions of two adjacent crimping guide plates are usually abutting together, which is not conducive to rapid assembly. Moreover, this type of connector is not suitable for busbars where the conductive plate thickness is less than twice the protrusion thickness.

[0094] In this embodiment of the invention, the crimping guide 1 is flat, that is, there is no need to design the aforementioned protrusions on the crimping guide 1. Furthermore, as shown in the attached figure... Figure 4 and attached Figure 5As shown, the connector 100 also includes a plurality of insulated flexible supports 5 located between two adjacent crimping guides 1, for forming a predetermined spacing between the two crimping guides 1. This predetermined spacing allows for the insertion of the conductive plate 2001 of the busbar 200.

[0095] For example, the flexible support 5 can be made of insulating materials with a certain degree of elasticity, such as rubber or nylon.

[0096] By setting a flexible support 5 between the two crimping guide plates 1, the position of the crimping guide plates 1 is positioned by the flexible support 5, so that a gap is formed between the two crimping guide plates 1. In this way, the conductive plate 2001 of the busbar 200 can be easily inserted into the gap, making assembly more convenient and improving assembly efficiency.

[0097] In particular, because the flexible support 5 has a certain elasticity, the distance between the two pressing guide plates 1 is adjustable within a certain range. In this way, it can be applied to conductive plates 2001 of different thicknesses. After the conductive plate 2001 is inserted, when the fixing bolt 4 is tightened, the flexible support 5 can be compressed and deformed, ensuring that the conductive plate 2001 can be tightly clamped between the two conductive plates 2001.

[0098] For fixing bolt 4, see Figure 4 It includes a bolt body 41 and an insulating sleeve 42, wherein the insulating sleeve 42 is sleeved on the outside of the bolt body 41, and the flexible support 5 is located on the insulating sleeve 42. In this way, when the conductive plate 2001 of the busbar 200 is inserted to the distance, the end of the conductive plate 2001 abuts against the flexible support 5, and the flexible support 5 can effectively buffer the impact of the conductive plate 2001 on the insulating sleeve 42 of the fixing bolt 4.

[0099] The flexible support 5 can be designed in various structures, as long as it can be stably arranged between the two pressing guides 1. For example, the flexible support 5 can be sleeved on the outside of the fixing bolt 4. For example, the flexible support 5 can be provided with mounting holes to allow the insulating sleeve 42 of the fixing bolt 4 to pass through.

[0100] The surface of the flexible support 5 that contacts the conductive plate 2001 of the busbar 200 can be a plane. In some examples, the flexible support 5 is a rectangular plate with a mounting hole in the middle, so that the flexible support 5 can be sleeved on the outside of the insulating sleeve 42.

[0101] When assembling connector 100, with the nuts of fixing bolts 4 facing down, the components are assembled sequentially from bottom to top. Since the flexible support 5 can also be used for positioning the insulating baffle 2 and the crimping guide 1, the components can be automatically positioned when they are stacked on the fixing bolts 4 through their mounting holes from bottom to top, ensuring that each component is in the desired position. This not only effectively improves assembly efficiency, but also ensures that the insulating baffle 2 and the crimping guide 1 are relatively fixed in position under the positioning action of the flexible support 5, avoiding mutual displacement and wear during transportation, and also ensuring that the conductive contact surface of the crimping guide 1 is not damaged.

[0102] In some examples, one of the two pressure plates 3 has an internal thread in its mounting hole; the fixing bolt 4 is threadedly connected to the internally threaded pressure plate 3. See, for example, [link to example]. Figure 4 This allows the mounting hole of the pressure plate 3, which is away from the nut of the fixing bolt 4, to have an internal threaded hole, so that there is no need to use a nut to connect to the end of the fixing bolt 4 at that position.

[0103] In some examples, the pressure plate 3 also functions as a gasket, thus eliminating the need for a gasket. In addition, the mounting hole of the pressure plate 3 is a screw hole, so the pressure plate 3 functions as a nut, thus eliminating the need for a nut. This simplifies the structure of the connector 100, makes assembly simple, and helps improve assembly efficiency.

[0104] Insulating baffle 2 is used to support crimping guide 1, as shown in some examples. Figure 9 and attached Figure 10 As shown, the insulating baffle 2 is provided with a first end protrusion 21 and a second end protrusion 22. Further, as shown in the attached figure... Figure 10 As shown, one of the first end protrusion 21 and the second end protrusion 22 includes a first abutting surface 201 and a second abutting surface 202; the first abutting surface 201 is used to abut against the corresponding end of the crimping guide plate 1; the second abutting surface 202 is used to abut against the corresponding conductive plate 2001 of the busbar trough 200.

[0105] In some examples, the insulating baffle 2 is provided with a first end protrusion 21 and a second end protrusion 22 at its two ends, respectively; the protrusion of the upper one is longer.

[0106] For example, in application, the first end protrusion 21 is located on top and the second end protrusion 22 is located on the bottom. The first end protrusion 21, located on top, abuts against both the crimping guide plate 1 and the conductive plate 2001, while the second end protrusion 22 only abuts against the crimping guide plate 1. In other words, the first end protrusion 21 can be horizontally overlapped on the conductive plate 2001 of the busbar trough 200, thus avoiding the problem of insufficient contact area caused by the misalignment of the conductive plate 2001 and the crimping guide plate 1.

[0107] In some examples, for a conductive plate 2001, a portion of its end abuts against a second abutting surface 202 on a first end protrusion 21 of an insulating baffle 2 located on one side of the conductive plate 2001, and another portion of its end abuts against a second abutting surface 202 on a first end protrusion 21 of an insulating baffle 2 located on the other side of the conductive plate 2001.

[0108] See Figure 9 The insulating baffle 2 may further include a central protrusion 23 located between the first end protrusion 21 and the second end protrusion 22. Further integration Figure 5 The first end of the crimping guide plate 1 abuts against the first end protrusion 21, the second end of the crimping guide plate 1 abuts against the second end protrusion 22, and the mounting hole of the crimping guide plate 1 is fitted onto the middle protrusion 23.

[0109] For example, the first end protrusion 21 and the second end protrusion 22 are both flat, and the middle protrusion 23 is ring-shaped to fit with the mounting hole of the crimping guide plate 1.

[0110] When the crimping guide 1 is assembled onto the insulating baffle 2, the mounting hole in its middle is fitted into the middle portion, with one end abutting against the first end protrusion 21 and the other end abutting against the second end protrusion 22. In this way, the crimping guide 1 is assembled and positioned on the insulating baffle 2 to achieve a fixed position. In addition, the first end protrusion 21, the second end protrusion 22, and the middle protrusion 23 also help to increase the creepage distance of the crimping guide 1.

[0111] As described above, the busbar 200 includes a ground conductive plate 2001 among its multiple conductive plates 2001. The outermost of the multiple crimping guide plates 1 is used to connect to the ground conductive plate 20010. One of the pressure plates 3 abuts against the outermost insulating baffle 2, and the other pressure plate 3 has a gap with the outermost crimping guide plate 1. Furthermore, the connector 100 also includes an insulating flexible support member 5, and the gap between the pressure plate 3 and the outermost crimping guide plate 1 is maintained by the flexible support member 5. The flexible support member 5 has been described above and will not be repeated here.

[0112] In one example, for security reasons, see [link to example]. Figure 1 The connector 100 also includes a connector housing 6, which is fastened to the housing of the busbar 200 to enclose the crimping guide plate 1, insulating baffle 2, pressure plate 3 and fixing bolt 4 of the connector 100, so as to prevent accidental contact and electric shock.

[0113] In some examples, in order to monitor the good conductivity between the crimping guide 1 and the conductive plate 2001 of the busbar 200, the connector 100 provided in this embodiment of the invention further includes a plurality of temperature sensors and a plurality of indicating components; each temperature sensor is in contact with a crimping guide 1, and each indicating component is electrically connected to a temperature sensor; the indicating component is configured to indicate a temperature abnormality when the temperature sent by the corresponding temperature sensor exceeds a temperature threshold, for example, indicating poor contact between the crimping guide 1 and the conductive plate 2001.

[0114] The temperature of the pressing guide plate 1 is monitored using temperature sensors. The indicating component can be an indicator light, and there can be multiple indicator lights. Each indicator light is electrically connected to a temperature sensor to indicate the detection result of the temperature sensor. Alternatively, the indicating component can also be a display screen, with multiple temperature sensors electrically connected to the display screen, which can display the detection results of each temperature sensor.

[0115] During the connection between connector 100 and busbar 200, if there is poor contact between one of the crimping guides 1 and conductive plate 2001, the resistance between them will be high, generating more heat. The temperature sensor in contact with the crimping guide 1 will then detect a high temperature signal. The indicator component electrically connected to the temperature sensor will then indicate that the temperature sensor has detected a high temperature, such as by the indicator light illuminating. Based on the correspondence between the indicator component, the temperature sensor, and the crimping guide 1, it is possible to identify which crimping guide 1 and conductive plate 2001 have poor conductivity, which helps to troubleshoot connection faults.

[0116] When the connector 100 and the busbar 200 are connected, and the crimping guide plate 1 and the conductive plate 2001 are in good contact, the resistance between them is small and the heat generated is small. Therefore, the temperature sensor in contact with the crimping guide plate 1 will not detect high temperature. The indicator component electrically connected to the temperature sensor can then indicate that the temperature sensor has detected low temperature, such as when the indicator light does not illuminate.

[0117] As can be seen, connector 100 includes a temperature sensor and an indicator component, which allows technicians to clearly see whether the conductivity between each crimping guide 1 and conductive plate 2001 is good.

[0118] Based on the above description of the structure of connector 100, the connector 100 provided in this embodiment of the invention has at least the following effects:

[0119] (1) By improving the structure of the pressure plate 3, the fasteners of the connector 100 include only two pressure plates 3 and one fixing bolt 4. The pressure plate 3 also functions as a washer and nut, which simplifies the structure of the connector 100 and helps to improve assembly efficiency and assembly effect.

[0120] (2) By using the flexible support 5, a certain distance is always maintained between the two crimping guides 1 of the connector 100. This not only facilitates the insertion of the conductive plate 2001 of the busbar 200 and improves assembly efficiency, but also helps to prevent the insulating baffle 2 and the crimping guide 1 from colliding due to movement during transportation, thereby protecting the contact surface of the crimping guide 1. In addition, the flexible support 5 can also effectively buffer the impact of the conductive plate 2001 on the insulating sleeve 42 of the fixing bolt 4, preventing the insulating sleeve 42 from being squeezed and damaged.

[0121] (3) One of the first end protrusion 21 and the second end protrusion 22 of the insulating baffle 2 is designed with a second abutment surface 202, which can effectively prevent the problem of the conductive plate 2001 and the crimping guide plate 1 not being aligned when the connector 100 and the busbar 200 are assembled, and ensure that the contact area of ​​the two reaches the expected value.

[0122] (4) The connector 100 includes a temperature sensor and an indicator component, which can monitor in real time whether the conductivity between each crimping guide 1 and the conductive plate 2001 is good, so that users can understand in time whether the conductivity between each crimping guide 1 and the conductive plate 2001 is good, avoid power outage due to poor conductivity, and ensure continuous power supply in the IDC computer room where the power distribution system is applied.

[0123] On the other hand, see Figure 1 This invention also provides a power distribution system, which includes any of the connectors 100 described above and a plurality of busbar trunking 200, wherein the connector 100 connects two adjacent busbar trunking 200. It is understood that the power distribution system provided by this invention has all the advantages of the connector 100, and based on the use of the connector 100 provided by this invention, the assembly efficiency and assembly effect of the busbar trunking 200 and the connector 100 are significantly improved.

[0124] In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0125] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
