Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a 10PIN connector structure. Background Technology

[0002] In modern electronic devices, the performance of power connectors is crucial for stable system operation. For high-current transmission requirements, 10-pin connectors are widely used due to their multi-channel parallel design. However, this multi-pin structure faces significant heat dissipation challenges when carrying high currents.

[0003] When a large current flows through the terminals, the resistance generates Joule heat. If the heat cannot be dissipated in time, it will accumulate inside the connector, causing the temperature to rise. In existing 10-pin connector designs, the insulator usually only has basic insulation functions and lacks an effective heat dissipation structure inside. This conventionally designed insulator acts like a heat-shrinking layer, hindering the conduction of heat from the internal terminals to the outside, causing heat to concentrate near the terminals and forming localized high temperatures. This directly affects the connector's operational stability under high current.

[0004] Based on this, in order to optimize the working stability and reliability of existing connectivity, we propose a 10-pin connector structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing 10-pin connector designs, such as the insulator typically only having basic insulation functions and lacking an effective heat dissipation structure. Therefore, this invention proposes a 10-pin connector structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a PIN connector structure, including an insulator and a plurality of terminals embedded in the insulator. The insulator includes a mounting portion and a housing. The housing is sleeved on the outside of the mounting portion. The terminals are embedded inside the mounting portion, and the bottom end of the terminals extends through to the bottom of the mounting portion.

[0008] The outer shell and the mounting part are connected by a connecting part, which is used to separate a heat insulation cavity between the outer shell and the mounting part.

[0009] Furthermore, the mounting portion includes a connecting end and a plurality of columnar ends formed below the plurality of connecting ends, wherein four adjacent columnar ends contact each other in sequence and together form a heat-conducting groove.

[0010] Furthermore, the terminal includes a first post end and a second post end, which together form a T-shaped structure. The first post end is embedded inside the connection end, and the second post end is embedded inside the columnar end.

[0011] Furthermore, the inner top surface of the lower heat-conducting groove is connected to an upper heat-conducting groove extending into the connecting end, and the upper heat-conducting groove is located on the side of the first column end.

[0012] Furthermore, it also includes a foolproof post connected to the housing, the foolproof post and the housing being detachably connected.

[0013] Furthermore, the upper end of the anti-mistake post has a plug-in post, and the side of the plug-in post has an anti-mistake notch. The bottom of the housing is formed with a socket adapted to the plug-in post, and the inner side of the socket has an interference surface adapted to the anti-mistake notch.

[0014] Furthermore, the plug post has an elastic part formed by a deformation groove, and the end face of the elastic part has a locking protrusion. The inner side of the outer shell has a locking hole that communicates with the plug hole, and the locking protrusion and the locking hole engage with each other.

[0015] The 10PIN connector structure proposed in this utility model has the following advantages: By designing the insulator into a mounting part, a shell, and a connecting part, the connecting part forms a heat insulation cavity between the mounting part and the shell. The heat generated by the internal terminals during connection can be dissipated by the heat insulation cavity, thereby reducing the temperature of the shell. At the same time, compared with the existing technology of using an integral insulator to assemble the terminals, the heat dissipation efficiency of the internal terminals can be optimized, thus improving the working reliability of the connector.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 In one embodiment of this utility model, a 10-pin connector structure is disclosed. Specifically, the connector structure includes an insulator 1 and a plurality of terminals 2 embedded in the insulator 1. In this embodiment, ten terminals 2 are provided, which are arranged in two rows. The insulator 1 includes a mounting part 11 and a housing 12. The housing 12 is sleeved on the outside of the mounting part 11. The terminals 2 are embedded inside the mounting part 11, and the bottom end of the terminals 2 extends through to the bottom of the mounting part 11.

[0026] The outer shell 12 and the mounting part 11 are connected by a connecting part 13. The connecting part 13 is used to separate a heat insulation cavity 14 between the outer shell 12 and the mounting part 11. That is, by using a heat insulation cavity 14 between the mounting part 11 and the outer shell 12, the heat generated by the internal terminal 2 during connection can be dissipated by the heat insulation cavity 14, thereby reducing the temperature of the outer shell 12. At the same time, compared with the existing technology of using an integral insulator to assemble the terminal, the heat dissipation efficiency of the internal terminal 2 can also be optimized. Of course, the mounting part 11, the outer shell 12 and the connecting part 13 in this invention are designed as an integral molding structure, and the whole is made of plastic. In addition, the mounting part 11 in this embodiment can be formed with the terminal 2 by interference fit.

[0027] In some embodiments, the mounting portion 11 of the present invention includes a connecting end 111 and a plurality of columnar ends 112 formed below the plurality of connecting ends 111. The four adjacent columnar ends 112 contact each other in sequence and jointly form a lower heat conduction groove 113. That is, through the design of the lower heat conduction groove 113, the heat dissipated at the lower columnar ends 112 can be guided outward. By increasing the heat transfer path, the heat dissipation effect of the mounting portion 11 on the internal terminal 2 can be further improved.

[0028] Specifically, in this embodiment, the terminal 2 includes a first post end 21 and a second post end 22, which together form a T-shaped structure. The first post end 21 is embedded inside the connecting end 111, and the second post end 22 is embedded inside the columnar end 112. Of course, in this embodiment, the terminal 2 can be formed by stamping C3604 copper alloy. In this embodiment, the diameter of the first post end 21 is larger than that of the second post end 22. At the same time, the first post end 21 and the second post end 22 are coaxially arranged. Since the second post end 22 is inserted into the columnar end 112, the heat generated by the second post end 22 can be dissipated through the columnar end 112 towards the lower heat conduction groove 113 and the heat insulation cavity 14, thereby optimizing the heat dissipation effect of the second post end 22.

[0029] Furthermore, the aforementioned lower heat-conducting groove 113 dissipates heat from the second post end 22. To further conduct heat to the first post end 21, in this embodiment, an upper heat-conducting groove 114 extending into the connecting end 111 is connected to the inner top surface of the lower heat-conducting groove 113. The upper heat-conducting groove 114 is located on the side of the first post end 21. That is, in this embodiment, by opening the upper heat-conducting groove 114 inside the connecting end 111, since the upper heat-conducting groove 114 and the lower heat-conducting groove 113 are interconnected, the heat of the first post end 21 can be transferred outward by the upper heat-conducting groove 114 and then transferred to the outside via the lower heat-conducting groove 113, so as to further optimize the heat dissipation of the entire terminal 2 and improve the stability of the connector during operation.

[0030] It should be noted that this embodiment also includes a foolproof post 3 connected to the housing 12. The foolproof post 3 and the housing 12 are detachably connected. Specifically, by adopting a detachable connection between the foolproof post 3 and the housing 12 in this embodiment, firstly, the design and manufacturing of the housing 12 mold can be simplified. More importantly, when the foolproof post 3 is not assembled, the bottom of the entire housing 12 is flat, which facilitates the pressing of the terminal 2. After the housing 12 and the terminal 2 are connected, the installation of the foolproof post 3 can also avoid the problem of damage to the foolproof post 3 caused by the connection between the housing 12 and the terminal 2.

[0031] In some embodiments, the upper end of the anti-misalignment post 3 of this invention has a plug-in post 31, and the side of the plug-in post 31 has an anti-misalignment notch 32. The bottom of the outer shell 12 is formed with a socket 33 that is adapted to the plug-in post 31. The inner side of the socket 33 has an interference surface 34 that is adapted to the anti-misalignment notch 32. In this embodiment, the design of the anti-misalignment notch 32 and the interference surface 34 can be used to position the circumferential position of the plug-in post 31 when it is inserted into the socket 33, so as to avoid the problem of circumferential rotation of the anti-misalignment post 3 after connection.

[0032] Based on the above embodiments, in this embodiment, the plug-in post 31 is formed with an elastic part 35 through a deformation groove. The deformation groove is opened along the upper surface of the plug-in post 31 towards the side facing the anti-fool post 3. The end face of the elastic part 35 is formed with a locking protrusion 36. The inner side of the outer shell 12 has a locking hole 37 that communicates with the plug hole 33. The locking protrusion 36 and the locking hole 37 are engaged. That is, in this embodiment, when the anti-fool post 3 is inserted into the outer shell 12, the plug-in post 31 and the plug hole 33 are engaged and matched, and at the same time, the locking protrusion 36 on the elastic part 35 and the locking hole 37 are engaged, thus completing the installation and fixation of the entire anti-fool post 3.

[0033] In summary, by designing the insulator 1 with a mounting part 11, a housing 12, and a connecting part 13, the connecting part 13 forms a heat insulation cavity 14 between the mounting part 11 and the housing 12. The heat generated by the internal terminals 2 during connection can be dissipated by the heat insulation cavity 14, thereby reducing the temperature of the housing 12. At the same time, compared with the existing technology of using an integral insulator to assemble the terminals, the heat dissipation efficiency of the internal terminals 2 can be optimized, thus improving the working reliability of the connector.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
