Description

Technical Field

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

[0002] In the field of power engineering construction, existing plug connectors mainly adopt standardized mechanical interconnection structures, achieving electrical conduction through tightly machined pins and sockets. They are typically encased in weather-resistant insulation material to ensure operational safety. These devices are widely used in various power transmission and distribution line splicing scenarios, covering different voltage levels from low-voltage distribution to high-voltage transmission. Common configurations include straight-through, T-branch, and multi-parallel connections. In actual use, construction personnel select connector assemblies of the corresponding size according to cable specifications, and quickly install and remove them by rotating the bayonet or crimping the terminals. Some products are also equipped with anti-dislodgement safety devices to enhance connection stability.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] Existing connectors during assembly and production

[0005] In modular production and assembly, existing plug connectors generally adopt an integrated molded shell structure. The internal space layout and copper busbar mounting slots are preset according to specific specifications. In practical applications, such connectors are usually optimized for copper busbars of a single size. The fixing slots or positioning protrusions set on the inside of the shell can only match the installation requirements of copper busbars with corresponding cross-sectional area and length. When encountering copper busbars of different lengths, the internal space of the shell is pre-limited and lacks an adjustable accommodating structure, making it impossible to achieve compatible installation of copper busbars of different lengths in the same shell.

[0006] In addition, the connector terminals and plug housing are usually connected by a plug-in method, which leads to instability and shaking at the connection point after plugging in the copper busbar.

[0007] Therefore, this solution provides a connector to address the aforementioned problems. Utility Model Content

[0008] The purpose of this invention is to provide a connector to solve the problems in the prior art, such as the inability to compatiblely install copper busbars of different lengths in the same housing and the easy shaking and instability of the plug connection.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] A connector includes a housing mechanism, a plug mechanism, and a connector mechanism, wherein the plug mechanism and the connector mechanism are located at opposite ends of the housing mechanism; the housing mechanism includes an upper housing and a lower housing connected vertically by screws, and the bottom of the lower housing has an elongated rectangular groove; the plug mechanism includes a plug housing and a plug terminal inserted into the plug housing, and an adjusting ring is provided at the end of the plug terminal located outside the plug housing; the connector mechanism includes a connector terminal and a connector socket sleeved at one end of the connector terminal.

[0011] Preferably, a short copper busbar is provided at one end of the plug-in terminal inside the lower housing. The short copper busbar is connected to the plug-in terminal by screws and is located on one side of the adjusting ring. A bolt is provided at the other end of the short copper busbar, and the bottom of the bolt is located inside the long rectangular groove.

[0012] Preferably, the plug-in terminal is provided with a long copper busbar at one end inside the lower housing, and a short copper busbar is connected to the plug-in terminal by screws and is located on one side of the adjusting ring. The other end of the long copper busbar is provided with two bolts, and the bottom end of the bolts is located in a long rectangular groove.

[0013] Preferably, the upper and lower housings are provided with mounting holes and connecting screw holes at both ends, the outer periphery of the connector housing is provided with a snap-fit ​​part that fits into the mounting hole, and the outer periphery of one end of the connector seat is threaded to the connecting screw hole.

[0014] Preferably, the adjusting ring is threaded around the plug terminal and fits tightly against the end face of the plug housing.

[0015] Preferably, the end of the connector seat away from the housing mechanism is provided with a threaded connection connector cover.

[0016] Preferably, a dust cover is fitted onto one end of the connector housing outside the housing mechanism.

[0017] The beneficial effects of this utility model are:

[0018] I. The present invention features a long rectangular groove at the bottom of the lower housing that cooperates with a detachable short / long copper busbar. Through the flexible positioning of bolts one / two, the same housing mechanism can adapt to the installation requirements of copper busbars of different lengths. This breaks through the dependence of traditional integrated housings on copper busbars of a single specification and improves the versatility of connectors in diverse application scenarios.

[0019] Second, the adjusting ring of this utility model, through the interference fit formed by tightening the thread, expands the contact area between the tail of the plug terminal and the end face of the plug housing, eliminates the axial displacement caused by the copper busbar under force in the traditional plug structure, and ensures the stability and reliability of electrical connection under high voltage environment.

[0031] Please refer to the following. Figures 1 to 6 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back.

If a specific orientation changes, the directional indication will also change accordingly.

[0033] This utility model provides a connector, including a housing mechanism 1, a plug mechanism 2, and a connector mechanism 3, wherein the plug mechanism 2 and the connector mechanism 3 are respectively located at both ends of the housing mechanism 1;

[0034] The housing mechanism 1 includes an upper housing 11 and a lower housing 12 connected by screws. The bottom of the lower housing 12 is provided with a long rectangular groove 13.

[0035] The plug mechanism 2 includes a plug housing 21 and a plug terminal 23 that is inserted into the plug housing 21. An adjustment ring 24 is provided at one end of the plug terminal 23 located outside the plug housing 21.

[0036] The connector mechanism 3 includes a connector terminal 31 and a connector seat 32 that is sleeved on one end of the connector terminal 31;

[0037] The connector mechanism 3 is existing technology, while the connector terminal 31 has a connecting terminal inside for connecting external cables. The cable passes through the inside of the connector terminal 31 and connects to the wire nose. The wire nose is one of the parts in existing connectors and is not shown in the figure. The wire nose is connected to the short copper busbar 25 or the long copper busbar 28 by bolts. Bolt 1 27 and bolt 2 29 are the bolts used to connect the wire nose. The short copper busbar 25 and the long copper busbar 28 mentioned below are the same except for their length, so that the long rectangular groove 13 can be adapted to the installation of copper busbars and wire noses of different lengths.

[0038] In a further embodiment, a short copper busbar 25 is provided at one end of the plug-in terminal 23 located inside the lower housing 12. The short copper busbar 25 is connected to the plug-in terminal 23 by a screw 26 and is located on one side of the adjusting ring 24. A bolt 27 is provided at the other end of the short copper busbar 25. The bottom of the bolt 27 is located inside the long rectangular groove 13.

[0039] In this embodiment, the short copper busbar 25 is used to connect to the wire lug via bolt 27, and there are nuts and washers above the bolt 27.

[0040] In a further embodiment, a long copper busbar 28 is provided at one end of the plug-in terminal 23 located inside the lower housing 12, and a short copper busbar 25 is connected to the plug-in terminal 23 by a screw 26 and is located on one side of the adjusting ring 24. Two bolts 29 are provided at the other end of the long copper busbar 28, and the bottom end of the bolts 29 is located in the long rectangular groove 13.

[0041] In this embodiment, the long copper busbar 28 is used to connect with the wire lug via bolt 29. There are nuts and washers above the bolt 29, which allows the lower housing 12 to be modularly adapted to the copper busbar.

[0042] In a further embodiment, the upper housing 11 and the lower housing 12 are respectively provided with mounting holes 14 and connecting screw holes 15 at both ends. The outer periphery of the connector housing 21 is provided with a snap-fit ​​part 22, which fits into the mounting hole 14. The outer periphery of one end of the connector seat 32 is threadedly connected to the connecting screw hole 15.

[0043] In this embodiment, the inner wall of the connecting screw hole 15 is threaded and matches the thread on one end of the connector seat 32.

[0044] In a further embodiment, the adjusting ring 24 is threaded around the plug terminal 23 and fits tightly against the end face of the plug housing 21.

[0045] In this embodiment, after the adjusting ring 24 rotates at the thread of the plug terminal 23, it can fit tightly against the end face of the plug housing 21, thereby ensuring that the plug housing 21 and the plug terminal 23 cannot wobble after installation.

[0046] In a further embodiment, a threaded connection connector cover 33 is provided at the end of the connector seat 32 away from the housing mechanism 1.

[0047] In this embodiment, a rubber ring is embedded on the inner side of the connector seat 32 to protect the cable when it passes through the connector cover 33 and connects to the connector terminal 31 inside the connector seat 32.

[0048] In a further embodiment, a dust cover 4 is fitted onto one end of the connector housing 21 located outside the housing mechanism 1.

[0049] In this embodiment, the dust cover 4 is used to prevent dust from entering the plug terminals inside the plug housing 21 when the plug connector is not connected.

[0050] The working principle of this utility model is as follows:

[0051] When connector parts are modularly produced and assembled, if short copper busbars 25 or long copper busbars 28 need to be installed, they can be connected to one side of the plug terminal 23 by screws 26. After connection, the bottom of bolt 27 will be in the long rectangular groove 13 opened in the modular production housing 12. Thus, connectors of different specifications can be assembled in the same batch of housing mechanisms 1. Short copper busbars 25 or long copper busbars 28 can be connected to the terminal located in the connector terminal 31 by crimping lugs, and the other end of the terminal in the connector terminal 31 is connected to the external cable. Therefore, the housing mechanism 1 can not only adapt to short copper busbars 25 or long copper busbars 28 of different lengths, but also reduce the mold opening cost of producing housing mechanism 1.

[0052] When the plug terminal 23 is inserted into the interior of the plug housing 21, the exposed portion has threads on its periphery that allow the adjusting ring 24 to be bolted on. This allows the adjusting ring 24 to rotate and fit against one end of the plug housing 21. As a result, after the plug terminal 23 is inserted and installed inside the plug housing 21, the adjusting ring 24 can expand the contact area between the tail of the plug terminal 23 and the end face of the plug housing 21, thereby ensuring stability after installation and preventing it from shaking.

[0053] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
