Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a connector and a power supply component. Background Technology
[0002] Currently, when powering servers in a data center, plug-in connectors are typically used to power the servers through corresponding power interfaces. However, since most power interfaces are currently enclosed, when the plug-in connector is plugged into the power interface for an extended period of time, the heat generated by the electrical connection cannot be effectively dissipated, resulting in high temperatures at the connection point between the plug-in connector and the power interface, which in turn reduces the lifespan of both the plug-in connector and the power interface. Utility Model Content
[0003] The main purpose of this invention is to propose a connector that solves the problem that the heat generated when existing inserts are inserted into the power supply interface cannot be effectively dissipated.
[0004] To solve the above problems, this utility model proposes a connector, comprising:
[0005] A housing, comprising a main body and an insert portion connected to each other, wherein the main body has an internal mounting cavity, and the end of the main body away from the insert portion is an open end communicating with the mounting cavity; the insert portion includes two spaced-apart insert ends, each insert end having an insert groove, the two insert grooves being opposite to each other and both communicating with the mounting cavity; and
[0006] Two terminal blocks are provided, each of which includes a mounting portion and a plug portion connected to each other. At least a portion of each of the two mounting portions is respectively installed in the mounting cavity, and the other portion of each of the two mounting portions passes through and exposes the plug portion. One plug portion is provided in one plug slot. Each plug portion has a plug protrusion at the end away from the mounting portion. The two plug protrusions are arranged opposite to each other and form a plug gap.
[0007] In one embodiment, the housing further includes a partition plate disposed in the mounting cavity to divide the mounting cavity into a first cavity and a second cavity. The arrangement direction of the first cavity and the second cavity is consistent with the arrangement direction of the two insertion ends, and both are connected to the open end. The two mounting parts are respectively located in the first cavity and the second cavity.
[0008] In one embodiment, the top wall of the first cavity has a first opening, and the top wall of the second cavity has a second opening. The opening edges of the first opening and the second opening both have snap-fit portions, and the top ends of the two mounting portions are provided with snap hooks, with one snap hook snapping into one snap-fit portion.
[0009] In one embodiment, both the first cavity and the second cavity have a clearance opening on their bottom walls. The mounting portion includes a connected mounting section and a bent section. The two mounting sections are located in the first cavity and the second cavity, respectively, and the two bent sections extend out of the housing through the clearance opening.
[0010] In one embodiment, both of the bent sections are provided with a first through hole, which is used to thread the two terminal blocks and the server together.
[0011] In one embodiment, both terminal groups are double-layered structures, and the insertion protrusion of each terminal group includes a first protrusion and a second protrusion, with the first protrusion and the second protrusion spaced apart along the extension direction of the insertion slot.
[0012] In one embodiment, the housing further includes a positioning post, one end of which is connected to the junction of the main body and the bottom of the insertion part, and the other end is used to insert into the server.
[0013] In one embodiment, the diameter of the positioning post gradually decreases from one end to the other.
[0014] In one embodiment, the distance between the mounting portion and the cavity sidewalls of the first cavity and the second cavity is L, where 2mm≤L≤5mm.
[0015] This utility model also proposes a power supply component, including a plug and a connector, wherein the connector is the connector described above, and the plug is inserted into the plug gap.
[0016] This utility model proposes a connector, including a housing and two terminal groups. When an external insert is inserted into the insertion gap formed by the insertion protrusions of the two terminal groups, the heat generated between the insertion protrusions in the insertion slot and the insert, since the insertion slot and the mounting cavity are connected, will gradually flow into the mounting cavity, and then be discharged to the outside of the connector through the open end of the main body. This achieves efficient heat dissipation of the connector, thereby improving the service life of the insert and the connector as a power supply interface. Attached Figure Description

[0028] Currently, when powering servers in a data center, plug-in connectors are typically used to power the servers through corresponding power interfaces. However, since most power interfaces are currently enclosed, when the plug-in connector is plugged into the power interface for an extended period of time, the heat generated by the electrical connection cannot be effectively dissipated, resulting in high temperatures at the connection point between the plug-in connector and the power interface, which in turn reduces the lifespan of both the plug-in connector and the power interface.
[0029] To address the aforementioned problems, this utility model proposes a connector designed to solve the issue that the heat generated when existing inserts are inserted into a power supply interface cannot be effectively dissipated.
[0030] like Figures 1 to 4 In one embodiment, the connector 100 includes a housing 10 and two terminal piece groups 20. The housing 10 includes a main body portion 11 and an insertion portion 12 connected to each other. The main body portion 11 has a mounting cavity formed inside. The end of the main body portion 11 away from the insertion portion 12 is an open end 111. The insertion portion 12 includes two spaced insertion ends 121. Each insertion end 121 has an insertion groove 122. The two insertion grooves 122 are arranged opposite to each other and are connected to the mounting cavity. The bottom surface of the main body portion 11 adjacent to the open end 111 is used to be attached to the surface of the server. Each terminal piece group 20 includes a mounting portion 21 and a plug-in portion 22 connected to each other. The two mounting portions 21 are installed in the mounting cavity. One plug-in portion 22 is provided in one insertion groove 122. The end of each plug-in portion 22 away from the mounting portion 21 has a plug-in protrusion 221. The two plug-in protrusions 221 are arranged opposite to each other and form a plug-in gap for inserting the insertion component.
[0031] In this embodiment, the connector 100 is used in the field of electronic devices, mainly for powering a server host. Specifically, the housing 10 is the basic structure of the connector 100, serving to support and protect internal components and providing installation space for them. The main body 11 is the main load-bearing part of the connector 100, and its interior is hollow to form a mounting cavity. This cavity accommodates and fixes the mounting portions 21 of the two terminal groups 20. Notably, the end of the main body 11 furthest from the insertion portion 12 is open. This open design facilitates the installation and removal of the insertion components and, more importantly, allows the mounting cavity to directly connect with the external space, promoting air circulation and effectively dissipating the heat generated by the terminal groups 20 during operation, achieving efficient heat dissipation. The insertion portion 12 is the part of the connector 100 that mates with the external insertion component. It is integrally designed and manufactured with the main body 11 to ensure the stability of the connection between the two. It includes two spaced insertion ends 121, and insertion slots 122 are provided on both sides of the two insertion ends 121, which increases the installation space for the insertion part 22 of the terminal block 20, and also plays a guiding and positioning role for the insertion of the insertion parts.
[0032] The terminal assembly 20 is the core structure for connecting the connector 100 to the external insertion component. It is essentially a metal conductor. Specifically, the terminal assembly 20 includes an integrated mounting part 21 and a plugging part 22. The mounting part 21 is installed in the mounting cavity to ensure the installation stability of the terminal assembly 20 in the connector 100. The plugging part 22 extends into the insertion slot 122. At the same time, two plugging protrusions 221 arranged opposite to the two plugging parts 22 form a plugging gap. The external insertion component is inserted through this gap and tightly cooperates with the plugging protrusions 221 to achieve electrical connection and complete the circuit conduction.
[0033] The connector 100 proposed in this utility model includes a housing 10 and two terminal piece groups 20. The open end 111 of the main body 11 allows air to circulate between the inside of the connector 100 and the external environment, effectively promoting heat dissipation. When an external insert is inserted into the insertion gap formed by the insertion protrusions 221 of the two terminal piece groups 20, since the insertion groove 122 is connected to the mounting cavity, the heat generated between the insertion protrusions 221 and the insert in the insertion groove 122 will gradually flow into the mounting cavity, and then be discharged to the outside of the connector 100 through the open end 111 of the main body 11. This achieves efficient heat dissipation of the connector 100, thereby improving the service life of the insert and the connector 100 as a power supply interface.
[0034] like Figure 1In one embodiment, the housing 10 further includes a partition plate 13, which is disposed in the mounting cavity to divide the mounting cavity into a first cavity and a second cavity. The arrangement direction of the first cavity and the second cavity is consistent with the arrangement direction of the two insertion ends 121, and the two mounting parts 21 are respectively located in the first cavity and the second cavity.
[0035] In this embodiment, the partition plate 13 is disposed within the mounting cavity, and its connection with the housing 10 can be integrally injection molded, ensuring the stability of the connection between the two while reducing the processing difficulty. The partition plate 13 divides the mounting cavity into two independent chambers, namely a first chamber and a second chamber. The arrangement direction of the first and second chambers is consistent with the arrangement direction of the two insertion ends 121, allowing the two terminal pieces 20 to be accurately placed in their respective chambers. The design of the partition plate 13 serves to physically isolate the two terminal pieces 20, preventing mutual interference and avoiding collisions or misalignments that could lead to connection failure, thereby improving the practicality of the connector 100.
[0036] like Figure 1 and Figure 2 In one embodiment, the top wall of the first cavity is provided with a first opening 14, and the top wall of the second cavity is provided with a second opening 15. The opening edges of the first opening 14 and the second opening 15 are both provided with a snap-fit portion 16. The top ends of the two mounting portions 21 are provided with corresponding hooks 23, and one hook 23 snaps into one snap-fit portion 16.
[0037] In this embodiment, the first opening 14 and the second opening 15 are respectively opened on the top wall of the first cavity and the second cavity. The snap-fit part 16 is a strip-shaped structure, which is provided at the edge of the opening. The top of the two mounting parts 21 are respectively provided with a protrusion, so that the top of the mounting part 21 forms a hook 23 structure in the length direction. The hook 23 is snapped with the first opening 14 and the second opening 15, which improves the installation stability of the terminal piece group 20 in the housing 10.
[0038] In other embodiments, a limiting groove is also provided at the top of the inner end of the first cavity and the second cavity, and the top end of the mounting part 21 slides in the limiting groove, thereby limiting the left and right sides of the mounting part 21 and further improving the installation stability of the terminal piece group 20 in the housing 10.
[0039] like Figure 1 and Figure 2In one embodiment, both the bottom walls of the first cavity and the second cavity have a clearance opening 17. The mounting portion 21 includes a mounting section 211 and a bent section 212 connected to each other. The two mounting sections 211 are located in the first cavity and the second cavity, respectively. Both bent sections 212 extend out of the housing 10 through the clearance opening 17, and the extending direction of the two bent sections 212 is perpendicular to the insertion direction of the connector 100. The bent section 212 is used for connection with the server.
[0040] In this embodiment, both the first cavity and the bottom wall of the second cavity have a clearance opening 17, which provides passage space for the bent section 212 of the mounting part 21, allowing the bent section 212 to extend out of the housing 10 and connect to the server. The mounting part 21 consists of two parts: the mounting section 211 and the bent section 212, giving the mounting part 21 an overall L-shaped structure. The connection between the mounting section 211 and the bent section 212 can be welded or integrally designed to ensure the stability of the connection. The mounting section 211 mainly serves to fix the mounting inside the mounting cavity, ensuring the installation stability of the terminal piece group 20 within the housing 10. The bent section 212 extends out of the housing 10 through the clearance opening 17, and its extension direction is perpendicular to the insertion direction of the connector 100, so that the surface of the bent section 212 fits against the server and is connected. The connection method can be threaded connection, welding, or snap-fit connection, ensuring the overall installation stability of the connector 100 relative to the server.
[0041] like Figure 1 and Figure 4 In one embodiment, both bent sections 212 are provided with a first through hole 2121, which is used to thread the two end pieces 20 and the server.
[0042] In this embodiment, the first through hole 2121 is a threaded hole formed on the bent section 212. The specific number of these holes is not limited. When the connector 100 is installed on the server, threaded fasteners such as screws or bolts can be passed through the first through hole 2121 to tightly fix the bent section 212 to the corresponding connection part on the server, achieving a threaded connection between the two. By using a threaded connection, operators can quickly disassemble and replace the connector 100, thereby improving the flexibility of the connector 100's assembly and disassembly.
[0043] In other embodiments, the connection between the bent segment 212 and the server can also be a snap-fit connection.
[0044] like Figure 1 , Figure 2 and Figure 4In one embodiment, both end pieces 20 are double-layered structures, such that each insertion protrusion 221 includes a first protrusion 2211 and a second protrusion 2212, with the first protrusion 2211 and the second protrusion 2212 spaced apart along the extension direction of the insertion groove 122.
[0045] In this embodiment, the terminal piece group 20 is formed by stacking two identical structural layers together, thereby increasing the structural strength of the terminal piece group 20 and ensuring sufficient structural stability for stable operation under different working environments. Furthermore, the double-layer design results in the insertion protrusion 221 also having a first protrusion 2211 and a second protrusion 2212. These first protrusions 2211 and second protrusions 2212 are orderly distributed along the length of the insertion slot 122. When the insertion piece is inserted into the insertion gap, it simultaneously contacts the first protrusion 2211 and the second protrusion 2212, forming multi-point contact and increasing the contact area, thereby improving the stability and reliability of current transmission. The spaced first protrusions 2211 and second protrusions 2212 also increase the overall mechanical strength of the insertion protrusion 221, making it less prone to deformation and damage during frequent insertion and removal, thus improving the service life of the terminal piece group 20.
[0046] like Figure 1 and Figure 3 In one embodiment, the housing 10 further includes a positioning post 18, one end of which is connected to the junction of the main body 11 and the bottom of the insertion part 12, and the other end is used to insert into the server.
[0047] In this embodiment, the positioning post 18 and the main structure of the housing 10 are integrated into a single unit, ensuring the stability of their connection. The positioning post 18 is used to engage with the corresponding positioning hole on the server, achieving initial positioning of the connector 100 on the server and ensuring the accuracy of the connector 100's installation position. Simultaneously, the positioning post 18 provides a reference for the subsequent installation and connection of other components, making the entire installation process more orderly and efficient.
[0048] like Figure 1 and Figure 3 In one embodiment, the diameter of the positioning post 18 gradually decreases from one end to the other.
[0049] In this embodiment, the positioning post 18 has a frustum-shaped structure, meaning that the diameter of the positioning post 18 decreases continuously from its root to its head. This allows the positioning post 18, with its smaller diameter head, to be more easily aligned with and inserted into the positioning hole of the server. As the positioning post 18 gradually penetrates deeper into the positioning hole, the gradually increasing diameter portion will form a tight fit with the inner wall of the positioning hole, achieving a stable connection and further improving the installation stability of the connector 100.
[0050] like Figure 1 In one embodiment, the distance between the mounting part and the cavity sidewalls of the first cavity and the second cavity is L, where 2mm≤L≤5mm.
[0051] In this embodiment, if the distance between the two mounting portions 21 and the cavity sidewalls of the first and second cavities is small, it will affect the heat dissipation of the connector 100 itself. If the distance between the two mounting portions 21 and the cavity sidewalls of the first and second cavities is large, it will cause the connector 100 to occupy too much internal server space, while increasing the weight and manufacturing cost of the connector 100. Therefore, the distance between the mounting portions 21 and the cavity sidewalls of the first and second cavities is set to 2mm ≤ L ≤ 5mm. For example, L can be 2mm, 3mm, 5mm, etc. Within this range, it will not affect the heat dissipation performance of the connector 100, nor will it cause the connector 100 to occupy too much internal server space, while reducing its own production cost.
[0052] In other embodiments, the vertical height of the housing 10 is H, where 12mm ≤ H ≤ 24mm. If the vertical height of the housing 10 is too small, the internal installation space of the housing 10 will be too narrow, resulting in insufficient installation space for the terminal block assembly 20. If the vertical height of the housing 10 is too large, it will occupy too much internal server space and increase the weight and manufacturing cost of the connector 100. Therefore, the vertical height of the housing 10 is 12mm ≤ H ≤ 24mm. For example, H can be 16mm, 18mm, 20mm, etc. Within this range, the housing 10 can provide sufficient installation space for the terminal block assembly 20 without occupying too much internal server space, while also reducing its own production cost.
[0053] This utility model also proposes a power supply component (not shown), including a plug and a connector 100. The plug is inserted into the insertion gap to realize the normal operation of the power supply component. The specific structure of the connector 100 is as described in the above embodiments. Since the connector 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
[0054] The above description is merely an exemplary embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made using the contents of this utility model and its drawings under the technical concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
