Description

Technical Field

[0001] This application relates to the field of socket technology, and in particular to a terminal block, cabinet socket and electrical equipment. Background Technology

[0002] In server rack sockets, the terminals typically have openings at their ends, through which copper strips pass and are soldered. During production, as the copper strips are soldered to the terminals, the solder melts and fills the gap between the copper strip and the terminal opening. However, in actual soldering operations, the solder tends to flow downwards along the outer wall of the terminal, not only creating solder voids but also potentially causing excessive solder to flow onto the plastic parts, burning the plastic casing. Utility Model Content

[0003] Therefore, it is necessary to provide a terminal block, cabinet socket, and electrical equipment to address the problem of solder flowing downwards along the outer wall of the terminal during the soldering process.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a wiring terminal, including:

[0006] The main body has a first surface and a second surface that are distributed opposite to each other along a first direction. The main body has a connecting hole that passes through the first surface and the second surface.

[0007] A support member protrudes from the first surface or the second surface along the first direction, and at least one of the first surface or the second surface is provided with the support member. The support member is disposed below the connecting hole along the second direction.

[0008] The first direction and the second direction are perpendicular to each other.

[0009] In one embodiment of the first aspect, two lifting members are provided, and the two lifting members are disposed opposite to each other on the first surface and the second surface.

[0010] In one embodiment of the first aspect, the lifting member includes a receiving portion disposed below the connecting hole and flush with the edge of the connecting hole.

[0011] In one embodiment of the first aspect, the lifting member further includes an adapter, one end of which is connected to the receiving part and the other end of which is connected to the side of the main body.

[0012] In one embodiment of the first aspect, the receiving portion is a planar structure or an arc-shaped recessed structure.

[0013] Secondly, embodiments of this application also provide a cabinet socket, including multiple terminals as described in any of the above embodiments and multiple metal strips, each terminal corresponding to one of the L, N and E electrodes, and each metal strip being connected to multiple terminals of the same electrode.

[0014] In one embodiment of the second aspect, the metal strip passes through the connecting hole, the diameter of the connecting hole is larger than the outer diameter of the metal strip, and the outer surface of the metal strip is sealed and welded to the hole wall of the connecting hole.

[0015] In one embodiment of the second aspect, the cabinet socket further includes a socket module, wherein the end of the wiring terminal away from the connection hole is fixed inside the socket module.

[0016] In one embodiment of the second aspect, the cabinet socket further includes a panel mounted on the side of the socket module opposite to the wiring terminals.

[0017] Thirdly, embodiments of this application also provide an electrical device, including the wiring terminal or the cabinet socket described in any of the above embodiments.

[0018] Compared to related technologies, the advantages of this application are as follows: This application provides a terminal block, a cabinet socket, and electrical equipment. The terminal block includes a main body and a support member. The main body has a connection hole for copper strip welding, and the support member is located below the connection hole, thereby catching the solder during the welding process and preventing the solder from flowing onto the plastic parts.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] Power strips have multiple socket modules, each with multiple socket terminals. One end of each terminal is used to connect to a plug, and the other end connects to the power cord. For sockets with high reliability requirements, especially PDUs (Power Distribution Units), the internal connections between socket terminals of the same polarity between multiple modules are generally made by soldering copper strips or copper blocks in series.

[0041] See Figure 1 As shown, the tail of the socket terminal 1 is generally provided with an opening for the copper strip 2 to pass through, and soldering is performed on the copper strip through the opening. During the production process, when soldering the copper strip 2 to the socket terminal 1, multiple socket terminals 1 are already installed on the plastic parts of the power strip housing, with the terminals facing upwards. During soldering, a soldering gun 3 and a solder bar 4 are used to melt the solder and fill the gap between the copper strip 2 and the opening of the socket terminal 1. However, in actual soldering operations, if there is too little solder, it will lead to insufficient gap filling, insufficient contact, and high resistance. If there is too much solder, it will flow down the outer wall of the socket terminal 1, which will not only create soldering voids, but excessive solder may even flow onto the plastic parts, burning the plastic housing, resulting in poor connection quality, and the amount of solder is difficult to control, affecting production efficiency.

[0042] See Figure 2 As shown, in order to improve the above-mentioned problems, the embodiments of this application provide a terminal block 100 to improve the welding quality and production efficiency of the terminal block 100.

[0043] Specifically, the terminal block 100 includes a main body 110 and a support member 120. The main body 110 has a first surface 111 and a second surface 112 distributed opposite each other along a first direction x. The main body 110 has a connection hole 113 that penetrates both the first surface 111 and the second surface 112. The support member 120 protrudes from either the first surface 111 or the second surface 112 along the first direction x, and at least one of the first surface 111 or the second surface 112 has the support member 120. The support member 120 is positioned below the connection hole 113 along a second direction y.

[0044] Continue reading Figure 3As shown, for example, the main body 110 consists of 400 metal flat plates, such as copper sheets, aluminum sheets, alloy metal sheets, etc. No specific limitation is made here, as long as the conductivity requirements of the main body 110 are met. It should be noted that in this embodiment, the first direction x refers to the width direction of the terminal 100, and the second direction y refers to the height direction of the terminal 100 in a vertical state. The first direction x and the second direction y are perpendicular to each other. The first surface 111 and the second surface 112 refer to two opposite sides of the main body 110. The connecting hole 113 penetrates through the first surface 111 and the second surface 112 to facilitate the subsequent welding of the metal strip 200 to the main body 110 after passing through the connecting hole 113.

[0045] The support member 120 is perpendicular to the first surface 111 or the second surface 112, and its side is attached to or fixed to the main body 110. By positioning the support member 120 below the connecting hole 113, during the welding process, when some solder flows downwards, it can be caught by the support member 120, preventing the solder from continuing to flow downwards and causing the plastic part to burn. This provides welders with greater tolerance for errors when controlling the amount of solder, improving welding efficiency. For example, workers are much less likely to experience insufficient solder due to fear of solder flowing down. Simultaneously, the support member 120 can more effectively fill the gap between the connecting hole 113 and the metal strip 200, improving welding quality.

[0046] Continue reading Figure 4 As shown, in some embodiments, there are two lifting members 120, which are disposed opposite to each other on the first surface 111 and the second surface 112.

[0047] For example, a support member 120 is provided on both sides of the main body 110, and both support members 120 are close to the port of the connection hole 113, so that during the welding process between the main body 110 and the metal strip 200, welding can be performed from either side of the connection hole 113, and the solder can be received by the corresponding support member 120, thereby further improving the welding quality.

[0048] Continue reading Figure 5 and Figure 6 As shown, in some other embodiments, the support member 120 may be provided only on one of the first surface 111 and the second surface 112.

[0049] It should be noted that in this embodiment, the first surface 111 and the second surface 112 are only illustrative examples for ease of understanding of orientation. In actual application, the first surface 111 and the second surface 112 can be interchanged, and no specific limitation is made here. When the connecting hole 113 is provided with a support member 120 on only one side, the welding position needs to be limited, that is, the main welding is only performed on one side, so that the support member 120 can support the larger amount of solder used, and a small amount of solder can be used for touch-up welding on the other side.

[0050] In some embodiments, the lifting member 120 includes a receiving portion 121, which is disposed below the connecting hole 113 and flush with the edge of the connecting hole 113.

[0051] For example, the receiving part 121 is used to receive solder from the soldering process. Therefore, the receiving part 121 is positioned directly below the connecting hole 113, so that the solder flows onto the receiving part 121 under the action of gravity. At the same time, by setting the receiving part 121 flush with the edge of the connecting hole 113, the solder can be received by the receiving part 121 in the first place, avoiding the solder from adhering to the surface of the main body 110 and affecting the insertion stability of the main body 110.

[0052] Continue reading Figure 7 As shown, in some embodiments, the lifting member 120 further includes an adapter 122, one end of which is connected to the receiving part 121, and the other end is connected to the side of the main body 110.

[0053] For example, the terminal block 100 is initially a planar metal sheet structure, and is then processed through cutting or other techniques to obtain the terminal block 100. For instance, the metal sheet needs to be cut on both sides to obtain a main body 110 of a corresponding width. In this application, instead of directly cutting off the scrap material, the waste is bent to form a transition part 122 and a receiving part 121, with the receiving part 121 receiving solder during the welding process. This achieves effective utilization of waste material, avoids solder flow, and improves resource utilization.

[0054] Of course, in some other embodiments, a receiving part 121 can be provided only below the connecting hole 113 to meet the requirements for solder reception. It is understood that waste will also be generated during the drilling process of the connecting hole 113. In this embodiment, the drilling waste of the connecting hole 113 can be completed to one side, thus directly forming a receiving part 121 flush with the wall of the connecting hole 113, which also achieves efficient utilization of resources.

[0055] See again Figure 4 As shown, the two support components 120 can be reasonably selected according to the processing technology of the terminal block 100. For example, one support component 120 is formed from the punching waste of the connecting hole 113, and the other support component 120 is formed by bending the cutting waste on the side, which further improves the utilization rate of resources.

[0056] See again Figure 5 As shown, in some embodiments, the bottom of the connecting hole 113 is a straight edge, and the receiving part 121 can be a planar structure accordingly to meet the requirements of receiving solder at the connecting hole 113.

[0057] See again Figure 6As shown, in some embodiments, the bottom of the connecting hole 113 is an arc-shaped edge, and the receiving part 121 can be a corresponding arc-shaped recessed structure to meet the requirements of receiving solder at the connecting hole 113.

[0058] Of course, it is understandable that the shape of the receiving part 121 described above is only an example. The shape of the connecting hole 113 can also be circular, elliptical or similar to a cam shape, etc. The shape of the receiving part 121 can be adapted to the shape of the connecting hole 113, and no specific limitation is required here.

[0059] Continue reading Figure 8 As shown, an embodiment of this application also provides a cabinet socket 1000, including multiple terminals 100 as described in any of the above embodiments and multiple metal strips 200. Each terminal 100 corresponds to one of the L, N and E poles, and each metal strip 200 is connected to multiple terminals 100 of the same type of electrode.

[0060] This embodiment has the terminal block 100 of any of the above embodiments, and therefore has all the beneficial effects of the terminal block 100 of any of the above embodiments, which will not be described in detail here.

[0061] The Rack Socket 1000 is a power distribution unit specifically designed for rack-mount equipment. It belongs to the socket category and is primarily used to provide power distribution and protection for electrical equipment within the rack. Designed specifically for racks, the Rack Socket 1000 distributes power through socket combinations and supports functions such as surge protection, overload and short-circuit protection. It is commonly found in data centers, communication equipment rooms, and other scenarios requiring centralized power management.

[0062] Compared to ordinary power strips, the 1000 rack-mount socket features a more rational design, stricter quality and standards, longer trouble-free operating time, superior protection against leakage, overcurrent, and overload, resistance to damage from frequent plugging and unplugging, lower heat rise, and more flexible and convenient installation. It is suitable for industries with stringent power requirements. It also fundamentally eliminates the safety hazards of ordinary power strips, such as frequent power outages, burnouts, and fires caused by poor contact and insufficient load capacity.

[0063] For example, the L pole refers to the live wire, which is connected to the power supply and is responsible for sending current to the electrical equipment; the N pole refers to the neutral wire, which is connected to the power supply and is responsible for drawing current from the electrical equipment back to the power supply. The E pole refers to the grounding detection pole, which is connected to the ground through a wire. When the equipment leaks current, the fault current will flow to the ground through the equipment's grounding wire.

[0064] In a cabinet socket 1000, there are multiple terminals 100. Each terminal 100 is arranged in three rows. All terminals 100 in each row are soldered through the same metal strip 200 so that the polarity of the terminals 100 in the same row is the same. Three terminals 100 located in the same column form a plug position.

[0065] In some embodiments, the metal strip 200 passes through the connecting hole 113, the diameter of the connecting hole 113 is larger than the outer diameter of the metal strip 200, and the outer surface of the metal strip 200 is sealed and welded to the hole wall of the connecting hole 113.

[0066] For example, the metal strip 200 can be made of copper, aluminum, silver, or other materials, and the specific material can be selected based on a comprehensive consideration of conductivity and cost; no specific limitation is made here. By setting the diameter of the connecting hole 113 to be larger than the outer diameter of the metal strip 200, the metal strip 200 can pass sequentially through the connecting holes 113 of each terminal 100. Then, the gap between the metal strip 200 and the wall of the connecting hole 113 is filled with solder, thus achieving the connection between the metal strip 200 and the terminal 100.

[0067] In some embodiments, the cabinet socket 1000 further includes a socket module 300, and one end of the wiring terminal 100 away from the connection hole 113 is fixed inside the socket module 300.

[0068] For example, the socket module 300 includes a plastic housing and electronic components located inside the housing, forming a wiring position by fixing three mating terminals 100 of different polarities to the same socket module 300.

[0069] In some embodiments, the rack socket 1000 further includes a panel 400, which is mounted on the side of the socket module 300 opposite to the terminal block 100. The panel 400 can be fixed to each socket module 300 with screws to protect the entire rack socket 1000 and ensure an aesthetically pleasing appearance.

[0070] Embodiments of this application also provide an electrical device, including the terminal block 100 or cabinet socket 1000 in any of the above embodiments.

[0071] This embodiment has the wiring terminal 100 or cabinet socket 1000 of any of the above embodiments, and therefore has all the beneficial effects of the wiring terminal 100 or cabinet socket 1000 of any of the above embodiments, which will not be described in detail here.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
