Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and specifically relates to a multi-point contact bayonet-type electrical connector. Background Technology

[0002] Multi-point contact electrical connectors achieve highly reliable electrical connections by integrating multiple independent contact points. Their core design employs a redundant contact mechanism—each conductive path is supported by multiple sets of elastic contacts (such as spring pins or spring arrays) working together. Even if a single contact fails, the remaining contacts can still ensure stable transmission of current or signals.

[0003] In the actual use of electrical connectors, when the male end is plugged into the female end, in order to prevent the male end from separating from the female end due to accidental dragging of external lines, some electrical connectors use a threaded tube to connect the male end and the female end. Although this setting enhances the connection stability to a certain extent, this method has significant drawbacks: when it is necessary to separate the male end and the female end, the threaded tube needs to be rotated multiple times to unlock it. The operation process is cumbersome and time-consuming, making it difficult to meet the efficient needs of emergency maintenance or rapid replacement scenarios. Utility Model Content

[0004] To address the problem that multiple rotations of the threaded tube are required when separating the male and female ends, this invention proposes a multi-point contact bayonet-type electrical connector to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-point contact bayonet-type electrical connector, including a male end and a female end. The male end is sleeved on the outside of the female end. An elastic snap-fit ​​component is provided between the male end and the female end. A pressing component is provided inside the male end corresponding to the elastic snap-fit ​​component. An elastic pushing component is provided at one end of the male end. The elastic pushing component and the pressing component are connected together.

[0007] By fitting the male end over the outside of the female end, the male end and the female end are connected together, and the elastic snap-fit ​​assembly connects the male end and the female end together; the elastic pushing assembly pushes the squeezing assembly, so that the squeezing assembly squeezes the snap-fit ​​end of the elastic snap-fit ​​assembly downward.

[0008] Furthermore, the elastic snap-fit ​​assembly includes a storage groove, which has multiple slots on the outer surface of the female end. A Z-shaped spring is fixedly connected to the bottom of the inner wall of the storage groove, and a wedge-shaped snap-fit ​​block is fixedly connected to the top of the Z-shaped spring. A snap-fit ​​groove is formed on the inner wall of the male end corresponding to the wedge-shaped snap-fit ​​block.

[0009] Furthermore, a limiting groove is formed on the inner wall of the storage slot, and a limiting block is movably connected inside the limiting groove. The limiting block is fixedly connected to the wedge-shaped snap-fit ​​block.

[0010] Furthermore, the extrusion assembly includes a wedge-shaped extrusion groove, which is formed on the top of the inner wall of the snap-fit ​​groove. A wedge-shaped extrusion block is movably connected inside the wedge-shaped extrusion groove, and a push rod is provided on one side of the wedge-shaped extrusion block. One end of the push rod passes through the male end.

[0011] Furthermore, an I-shaped groove is provided on one side of the wedge-shaped extrusion block, and a connecting plate is movably connected inside the I-shaped groove. The other end of the push rod is fixedly connected to the connecting plate.

[0012] Furthermore, the elastic pushing component includes a storage cavity, and multiple storage cavities are provided inside the male end of the corresponding pushing rod. A pushing disk is movably connected inside the storage cavity, and the pushing disk is fixedly connected to the pushing rod. A return spring is fixedly connected between one side of the pushing disk and the inner wall of the storage cavity, and a pushing ring is fixedly connected to one end of the pushing rod.

[0013] Furthermore, a guide groove is provided on the outer surface of the female end, and a guide block is movably connected inside the guide groove. The guide block is fixedly connected to the inner wall of the push ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses an elastic snap-fit ​​component to fix the male end to the outside of the female end. At the same time, the elastic pushing component pushes the squeezing component, which causes the squeezing component to move downward and squeeze the snap-fit ​​end of the elastic snap-fit ​​component. When the snap-fit ​​end no longer snaps and limits the male end, the male end can move out from the outside of the female end under the push of the elastic pushing component. The above configuration makes it convenient to separate the male end from the female end by simply pushing the elastic pushing component.

[0016] 2. This utility model pushes the male end, which is fitted on the outside of the female end, so that the moving male end can push the wedge-shaped locking block into the storage groove through the inner wall. After the male end and the female end are connected, the Z-shaped spring can push the wedge-shaped locking block into the inside of the locking groove, so that the wedge-shaped locking block can lock and limit the male end through the locking groove. The above setting makes it convenient to connect the male end and the female end by automatically locking and limiting the male end after the male end moves to the predetermined position.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0032] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0033] Please see Figures 1-10 As shown, this utility model is a multi-point contact bayonet-type electrical connector, including a male end 1 and a female end 2. The male end 1 is sleeved on the outside of the female end 2. An elastic snap-fit ​​component 3 is provided between the male end 1 and the female end 2. A pressing component 4 is provided inside the male end 1 corresponding to the elastic snap-fit ​​component 3. An elastic pushing component 5 is provided at one end of the male end 1. The elastic pushing component 5 is connected to the pressing component 4.

[0034] By fitting the male end 1 onto the outside of the female end 2, the male end 1 and the female end 2 are connected together, and the elastic snap-fit ​​component 3 connects the male end 1 and the female end 2 together; the elastic pushing component 5 pushes the squeezing component 4, so that the squeezing component 4 squeezes the snap-fit ​​end of the elastic snap-fit ​​component 3 downward.

[0035] By fitting the male end 1 onto the outside of the female end 2, the male end 1 and the female end 2 are connected together, and the elastic locking component 3 connects the male end and the female end together. When separating the male end 1 from the female end 2, the elastic pushing component 5 directly pushes the squeezing component 4. Under the action of the pushing force, the squeezing component 4 moves downward and squeezes the locking end of the elastic locking component 3 downward, so that the locking end no longer locks and limits the male end 1. At this time, the elastic pushing component 5 is directly pushed, so that the male end 1 moves out from the outside of the female end 2 under the push of the elastic pushing component 5.

[0036] The male end 1 can be fixed to the outside of the female end 2 by the elastic snap-fit ​​component 3. At the same time, the elastic push component 5 pushes the squeezing component 4, which can make the squeezing component 4 move downward continuously and squeeze the snap-fit ​​end of the elastic snap-fit ​​component 3. When the snap-fit ​​end no longer snaps and limits the male end 1, the male end 1 can be moved out from the outside of the female end 2 by the push of the elastic push component 5. The above configuration makes it convenient to separate the male end 1 from the female end 2 by simply pushing the elastic push component 5.

[0037] In one embodiment, the elastic snap-fit ​​assembly 3 includes a receiving groove 301. The receiving groove 301 has multiple openings on the outer surface of the female end 2. A Z-shaped spring piece 302 is fixedly connected to the bottom of the inner wall of the receiving groove 301. A wedge-shaped snap-fit ​​block 303 is fixedly connected to the top of the Z-shaped spring piece 302. A snap-fit ​​groove 304 is opened on the inner wall of the male end 1 corresponding to the wedge-shaped snap-fit ​​block 303.

[0038] By fitting the male end 1 onto the outer surface of the female end 2 and continuously moving the male end 1, the moving male end 1 can press downwards against the wedge-shaped locking block 303 through the inner wall, thereby allowing the wedge-shaped locking block 303 to move into the storage groove 301. When the male end 1 and the female end 2 are connected, the locking groove 304 and the wedge-shaped locking block 303 are aligned vertically. At this time, the Z-shaped spring piece 302 can push the wedge-shaped locking block 303 into the locking groove 304, thereby limiting the male end 1 through the locking groove 304, so that the male end 1 and the female end 2 will not separate arbitrarily. The above configuration allows the wedge-shaped locking block 303 to automatically limit the male end 1 when the male end 1 moves to the outside of the female end 2, making the operation of connecting the male end 1 and the female end 2 more convenient.

[0039] In one embodiment, for the aforementioned storage slot 301, a limiting groove 305 is formed on the inner wall of the storage slot 301, and a limiting block 306 is movably connected inside the limiting groove 305. The limiting block 306 is fixedly connected to the wedge-shaped snap-fit ​​block 303.

[0040] When the wedge-shaped latching block 303 moves inside the storage slot 301, it can drive the limiting block 306 to slide inside the limiting groove 305. In the above configuration, since the limiting groove 305 can guide the wedge-shaped latching block 303 through the limiting block 306, the wedge-shaped latching block 303 is less likely to tilt when it moves inside the storage slot 301. At the same time, under the restriction of the limiting groove 305 and the limiting block 306, the wedge-shaped latching block 303 will not move out of the storage slot 301 under the push of the Z-shaped spring 302.

[0041] In one embodiment, the extrusion assembly 4 includes a wedge-shaped extrusion groove 401, which is formed on the top of the inner wall of the snap-fit ​​groove 304. A wedge-shaped extrusion block 402 is movably connected inside the wedge-shaped extrusion groove 401. A push rod 403 is provided on one side of the wedge-shaped extrusion block 402, and one end of the push rod 403 passes through the male end 1.

[0042] By pushing the push rod 403 on the outside of the male end 1, the push rod 403 can push the wedge extrusion block 402 inside the wedge extrusion groove 401. At this time, the wedge extrusion block 402 moves downward at an angle under the guidance of the wedge extrusion groove 401, so that the wedge extrusion block 402 can squeeze the wedge snap block 303 into the inside of the receiving groove 301, so that the wedge snap block 303 no longer limits the male end 1.

[0043] In one embodiment, for the wedge-shaped extrusion block 402, an I-shaped groove 404 is provided on one side of the wedge-shaped extrusion block 402, and a connecting disk 405 is movably connected inside the I-shaped groove 404. The other end of the push rod 403 is fixedly connected to the connecting disk 405.

[0044] The push rod 403 can push the wedge-shaped extrusion block 402 through the connecting plate 405. When the wedge-shaped extrusion block 402 moves downward at an angle, the connecting plate 405 can slide inside the I-shaped groove 404. The connection plate 405 and the I-shaped groove 404 are designed so that the wedge-shaped extrusion block 402 can move downward at an angle without the connection between the push rod 403 and the wedge-shaped extrusion block 402 being damaged. This allows the push rod 403 to drive the wedge-shaped extrusion block 402 to reset through the I-shaped groove 404 and the connecting plate 405.

[0045] In one embodiment, the elastic pushing component 5 includes a receiving cavity 501. The receiving cavity 501 has multiple openings inside the male end 1 corresponding to the pushing rod 403. A pushing disk 502 is movably connected inside the receiving cavity 501. The pushing disk 502 is fixedly connected to the pushing rod 403. A return spring 503 is fixedly connected between one side of the pushing disk 502 and the inner wall of the receiving cavity 501. A pushing ring 504 is fixedly connected to one end of the pushing rod 403.

[0046] The return spring 503 can push the push rod 403 via the push plate 502, and the wedge-shaped pressing block 402 will not move out of the wedge-shaped pressing groove 401 under the pull of the push rod 403. This setting allows the wedge-shaped locking block 303 to move normally into the locking groove 304 under the push of the Z-shaped spring 302 after the male end 1 is moved to the outside of the female end 2. When it is necessary to separate the male end 1 from the female end 2, the push ring 504 directly pushes several push rods. The push rod 403 is pushed, and at this time the push rod 403 squeezes the return spring 503 through the push plate 502. At the same time, the push rod 403 continuously pushes the wedge-shaped compression block 402. When the wedge-shaped compression block 402 pushes the wedge-shaped locking block 303 into the inside of the receiving groove 301, the push ring 504 comes into contact with one end of the male end 1. At this time, the push ring 504 is pushed, so that the male end 1 moves out from the outside of the female end 2 under the push of the push ring 504.

[0047] In one embodiment, for the aforementioned female end 2, a guide groove 6 is provided on the outer surface of the female end 2, and a guide block 7 is movably connected inside the guide groove 6. The guide block 7 is fixedly connected to the inner wall of the push ring 504.

[0048] When the male end 1 is moved to the outside of the female end 2, the guide block 7 is aligned with the guide groove 6, so that when the male end 1 moves to the outside of the female end 2, the guide block 7 can slide inside the guide groove 6; under the guidance of the guide block 7 and the guide groove 6, the wedge-shaped locking block 303 can correspond vertically with the locking groove 304, so that the wedge-shaped locking block 303 can move normally into the locking groove 304.

[0049] Through the above technical solution, 1. The elastic snap-fit ​​component 3 can fix the male end 1 to the outside of the female end 2. At the same time, the elastic pushing component 5 pushes the squeezing component 4, which allows the squeezing component 4 to move downward continuously and squeeze the snap-fit ​​end of the elastic snap-fit ​​component 3. When the snap-fit ​​end no longer snaps and limits the male end 1, the male end 1 can move out from the outside of the female end 2 under the push of the elastic pushing component 5. The above setting makes it convenient to separate the male end 1 from the female end 2 by directly pushing the elastic pushing component 5; 2. By fitting the female end 1 to the female end 2, the male end 1 can be fixed to the outside of the female end 2. The male end 1 on the outside of end 2 is pushed, and the moving male end 1 can push the wedge-shaped locking block 303 into the storage groove 301 through the inner wall. After the male end 1 is connected with the female end 2, the Z-shaped spring piece 302 can push the wedge-shaped locking block 303 into the inside of the locking groove 304, so that the wedge-shaped locking block 303 locks and limits the male end 1 through the locking groove 304. The above setting makes it possible for the wedge-shaped locking block 303 to automatically lock and limit the male end 1 after the male end 1 moves to the predetermined position, so that the operation of connecting the male end 1 and the female end 2 is also more convenient.
