Technical Field

[0001] This utility model relates to the field of signal connector technology, specifically a floating multifunctional circular connector. Background Technology

[0002] In modern industrial equipment, new energy vehicles, power systems, and automation control, the performance requirements for electrical connectors are increasingly demanding. They not only need to transmit large currents of tens or even hundreds of amperes to meet power requirements, but also need to simultaneously integrate the transmission of multiple control signals, sensor signals, and data communication signals. Traditional solutions typically use separate power connectors and signal connectors, which not only occupies valuable equipment space and increases installation complexity, but also reduces the overall reliability of the system due to multiple mating operations and increases the risk of wiring errors.

[0003] Some hybrid connectors currently on the market, while attempting to integrate power and signal, often lack effective floating compensation designs to address installation misalignment. Some products with floating functionality have limited floating range, complex structures, high costs, and insufficient anti-mis-mating features, making them unsuitable for the stringent requirements of high-reliability industrial applications. Therefore, this utility model provides a solution to the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a floating, multifunctional circular connector, which at least solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A floating multi-functional circular connector includes a housing, wherein at least one guide post and at least one post groove are provided inside the housing, and the housing serves as the main support and protection structure of the connector. The connector is provided with a placement groove, at least one mating post and a signal connector. The mating post is adapted to the shape and position of the post groove. The placement groove is used for precise alignment of the mating post and for external connection of the signal connector. A connecting plate connects the housing to the connector. A plug-in panel is provided with a guide hole, a connecting post, and a connecting hole, wherein the shape and position of the guide hole are adapted to the guide post; The connector is connected to the plug-in panel via a sliding locking structure.

[0006] As a further embodiment of this utility model, the sliding locking structure includes a sliding track disposed on the outer periphery of the connector and a locking buckle disposed on the inner periphery of the plug-in panel, wherein the sliding track and the locking buckle cooperate with each other.

[0007] As a further embodiment of this utility model, the sliding track is an L-shaped or J-shaped groove, and the locking buckle is a protrusion that can undergo elastic deformation.

[0008] As a further embodiment of this utility model, the housing is also provided with a slot, and the connector is provided with a protrusion that mates with the slot.

[0009] As a further embodiment of this utility model, the difference between the cross-sectional diameter of the docking column and the cross-sectional aperture of the column groove is between 0.05mm and 0.5mm.

[0010] As a further embodiment of this utility model, the cross-section of the docking post is one of a circle, an ellipse, or a polygon, and the cross-sectional shape of the post groove is the same as the cross-sectional shape of the docking post.

[0011] As a further embodiment of this invention, the connector also includes a signal terminal and a wire terminal. One end of the signal terminal is connected to a signal line, and the other end is connected to the signal connector. One end of the wire terminal is connected to a wire, and the other end extends into the placement groove of the connector.

[0012] As a further improvement of this utility model, a clamp is provided on the signal terminal.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides a floating multifunctional circular connector, including a housing 1, wherein at least one guide post 101 and at least one post groove 102 are provided inside the housing 1; Connector 2, wherein the connector 2 is provided with a placement groove 21, at least one docking post 22 and a signal connector 23, wherein the docking post 22 is adapted to the shape and position of the post groove 102; Connecting plate 3, the connecting plate 3 connects the housing 1 and the connector 2; The plug-in panel 4 is provided with a guide hole 41, a connecting post 42 and a connecting hole 43, wherein the guide hole 41 is adapted to the shape and position of the guide post 101; The connector 2 is connected to the plug-in panel 4 via a sliding locking structure.

[0023] The housing 1 serves as the main support and protection structure of the connector. Inside it are guide posts 101 and post grooves 102. The connector 2 is a key component that carries the contacts. Inside it are placement slots 21 for accommodating internal components, mating posts 22 for precise alignment, and signal connectors 23 for external connections.

[0024] The cooperation between the guide post 101 and the guide hole 41 constitutes the first-level guiding system in the connector insertion process, which can roughly guide the connector head to align with the insertion panel in the initial stage, providing a basis for blind insertion.

[0025] In some embodiments, the sliding locking structure includes a sliding track disposed on the outer periphery of the connector 2 and a locking buckle disposed on the inner periphery of the plug panel 4, wherein the sliding track and the locking buckle cooperate with each other.

[0026] The plug panel 4 is used to fix the entire connector to the device panel. It has a guide hole 41 that mates with the housing guide post, a connecting post and a connecting hole for fixing the panel. The signal is introduced through the signal line 5 and passes through the signal terminal 6. The clamp 61 on the signal terminal 6 is used to fasten the cable and connect it to the signal connector inside the connector. The high current passes through the wire and enters the high power contact inside the connector through the wire terminal.

[0027] In some embodiments, the sliding track is an L-shaped or J-shaped groove, and the locking buckle is a protrusion that can undergo elastic deformation.

[0028] The connector and the plug panel are connected and locked through a specific track and snap-fit ​​mechanism. This structure is not completely rigid, but in the locked state, the connector is allowed to float a certain amount in the horizontal plane relative to the plug panel that is fixedly installed on the equipment. The sliding locking floating design allows for a radial float of ±1.5mm, which can effectively compensate for various installation misalignments and deformations, avoid the connector from bearing unnecessary mechanical stress, and significantly improve the adaptability to harsh industrial environments and the stability of long-term connections.

[0029] In some embodiments, the housing 1 is further provided with a slot 103, and the connector 2 is provided with a protrusion that mates with the slot 103.

[0030] The mating of the mating post 22 and the post slot 102 constitutes the second-level precision alignment system. After the guide system completes the initial alignment, the mating post is precisely inserted into the post slot, ensuring that the high-power contacts and signal contacts are completely aligned, thus guaranteeing a reliable electrical connection. This mating structure can also be designed as an anti-misfit mechanism, for example, by using posts and slots of different diameters or non-circular cross-sections, ensuring that only connectors with matching specifications can be successfully aligned and inserted, effectively preventing misoperation.

[0031] In some embodiments, the difference between the cross-sectional diameter of the mating post 22 and the cross-sectional aperture of the groove 102 is between 0.05 mm and 0.5 mm. In some embodiments, the cross-section of the docking post 22 is one of a circle, an ellipse, or a polygon, and the cross-sectional shape of the groove 102 is the same as the cross-sectional shape of the docking post 22.

[0032] In some embodiments, the connector further includes a signal terminal 6 and a wire terminal 7. One end of the signal terminal 6 is connected to the signal line 5, and the other end is connected to the signal connector 23. One end of the wire terminal 7 is connected to the wire 8, and the other end extends into the placement groove 21 of the connector 2.

[0033] In some embodiments, a clamp 61 is provided on the signal terminal 6.

[0034] The clamp 61 design on signal terminal 6 enhances the robustness of the cable connection, provides effective strain relief, and improves reliability in vibration environments.

[0035] This invention integrates power transmission and signal transmission into one unit. The connector internally features at least one pair of high-power contacts and multiple signal contacts. The high-power contacts utilize robust circular male-female contact pairs, and their current carrying capacity can be switched and adapted within a wide range from 100A to 350A by selecting contact materials of different diameters to meet the power requirements of various devices. In a preferred embodiment, this invention has 35 signal contacts used to transmit various control, detection, and data signals, with each signal contact having a maximum current carrying capacity of 1A.

[0036] The preferred layout is to arrange two high-power contacts in a straight line on both sides of the connector's plastic body, while densely and orderly arranging 35 signal contacts in the area between the two high-power contacts, forming a compact and efficient layout.

[0037] The assembly and operation process of this utility model is as follows: The high-power contact and signal contact are pre-installed and fixed into the placement groove 21 of the connector 2. The wire 8 is crimped to the wire terminal 7 and then connected to the tail of the high-power contact. The signal wire 5 is crimped to the signal terminal 6, and the cable can be secured against pulling using the clamp 61 on it, before being connected to the signal connector 23 at the tail of the connector 2. Assemble the connector 2 (with the cable already connected) and the connecting plate 3, and then insert this assembly into the housing 1 from the rear. At this time, the mating post 22 on the connector 2 should be aligned with the groove 102 inside the housing 1. Use fasteners to fix both to the housing 1 as a whole via the connecting plate 3; Install the plug-in panel 4 independently to the designed location on the equipment chassis or panel, and secure it firmly; Holding the assembled connector body, including the housing 1 and connector 2, slowly move the guide post 101 at the front end of the housing 1 towards the guide hole 41 on the mating panel 4. Once the guide post 101 enters the guide hole 41, initial rough positioning is completed. Continuing to move forward, the contact portion at the front end of the connector 2 begins to make contact with the corresponding contact points fixed to the back of the mating panel 4 (not fully shown in the diagram). Finally, the mating post 22 on the connector 2 precisely inserts into the corresponding groove 102 inside the housing 1, achieving final precise positioning and ensuring good contact of all electrical contacts. Then, operate the sliding locking mechanism on the connector housing, such as rotating or pushing the latch, to securely lock the connector 2 to the mating panel 4. When the device is misaligned in the radial XY plane between the plug panel 4 and the connector body due to vibration, thermal deformation or installation tolerance, the sliding locking mechanism is not rigidly fixed at a dead point, but allows for a small relative displacement. Therefore, the connector head 2 can drive the entire connector body to float ±1.5mm relative to the fixed plug panel 4, thereby eliminating the stress caused by the misalignment, ensuring that the electrical connection is always in good condition, and without damaging the connector itself.

[0038] The embodiments of this utility model are provided to clearly illustrate the technical solution of this utility model and are not intended to limit it. For those skilled in the art, various improvements and modifications can be made based on the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. For example, the number and position of the guide posts and grooves can be varied; the specific mechanical implementation of the sliding lock can have multiple designs; the number and arrangement of the contacts can be adjusted according to specific applications; the magnitude of the floating amount can be fine-tuned through design changes, etc. These variations and substitutions based on the core concept of this utility model all fall within the scope of protection of this utility model.

[0039] 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.
