Description

Technical Field

[0001] This utility model belongs to the field of mating connectors, and more specifically, relates to a mating connector. Background Technology

[0002] As a highly efficient and convenient electrical connection element, plug-in connectors are widely used in electronic equipment, industrial control and new energy fields. Their core function is to achieve rapid connection and disconnection through the plug-in structure, ensuring stable transmission of current or signals.

[0003] However, currently, most connectors use a screw-locking structure to secure the wire harness, such as using a metal clamping plate with an M3 or M2.5 screw to crimp and fix the wires. This design requires operators to tighten each screw individually with a screwdriver, which significantly reduces production efficiency during mass assembly.

[0004] Furthermore, existing connectors typically require multiple internal fixing structures to prevent cable loosening or misalignment, such as nylon cable clips, cable dividers, or metal spring clips for auxiliary positioning. For example, a certain type of industrial connector requires a triple fixing structure consisting of a guide groove, an insulating partition, and a tail sheath, increasing the overall number of components by more than 30%. This not only increases the connector housing size but also raises labor costs due to the complexity of the assembly process.

[0005] In view of this, this utility model is proposed. Utility Model Content

A through groove adapted to the wedge-shaped block is opened on the top of the combination box.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] This invention, through the cooperation between the snap-fit ​​mechanism and the wire harness fixing structure, allows multiple slave wires to be fixed at once during the subsequent assembly of the main wire and connector, eliminating the need for personnel to use additional tools.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a mating connector, including a connector head 1 and a plug 2. Each of the connector head 1 and plug 2 has a snap-fit ​​assembly structure on one side. A connecting cylinder 3 is provided on the relatively distant side of each of the connector head 1 and plug 2. A wire harness fixing structure is provided at one end of the connecting cylinder 3, and a main wire 4 is inserted into the wire harness fixing structure. Three branch wires 5 are provided at the end of the main wire 4. A straight groove 6 is provided on one side of the connecting cylinder 3 for the branch wires 5 to enter. A slot 7 is provided at the axis of the connecting cylinder 3, and a sliding groove 8 communicating with the straight groove 6 is provided on one side of the slot 7. A snap-fit ​​structure for securing the position of the branch wires 5 is slidably connected within the sliding groove 8. The wire harness fixing structure and the connecting cylinder 3 are threadedly connected, and the wire harness fixing structure and the snap-fit ​​structure cooperate with each other.

[0029] This invention, through the cooperation between the snap-fit ​​mechanism and the wire harness fixing structure, can fix multiple slave wires at once when assembling the main wire 4 and the connector, without the need for personnel to use extra tools. In addition, during the process of fixing the slave wires, the wire harness fixing structure will fix the position of the main wire 4, thereby reducing the procedures and operational difficulty of installing the connector.

[0030] The wire harness fixing structure includes a combination cylinder 9. A connecting plate 10 is fixedly connected to the bottom of the inner wall of the combination cylinder 9. An insertion hole for inserting the branch wire 5 is opened through the opposite side of the connecting plate 10. A rod 11 is fixedly connected to the top of the connecting plate 10. A groove 12 for inserting the rod 11 is opened on the top of the combination cylinder 9. A connecting rod 13 is fixedly connected to the axis of the connecting plate 10. One end of the connecting rod 13 is connected to a push block 14 that can slide into the slot 7 of the groove 8. The rod 11 can be inserted into the groove 12 inside the combination cylinder 9 to prevent the connecting plate 10 from rotating. It should be noted that by combining the combination cylinder 9 and the rod 11 together, the branch wire 5 can be prevented from being broken when the connector needs to be disassembled later.

[0031] A first nut 15 is threadedly connected to the outer circumference of the combined cylinder 9. A second nut 16 is fixedly connected to the outer circumference of the first nut 15, and the second nut 16 is threadedly connected to the connecting cylinder 3. The first nut 15 and the second nut 16 serve a guiding function, while the first nut 15 prevents the second nut 16 from slipping excessively. Furthermore, the combined cylinder 9 has an I-shaped cross-section. It should be noted that the second nut 16 moves synchronously during the rotation of the first nut 15. To further clarify, the external thread on the outer wall of the connecting cylinder 3 and the thread pitch at the outer nut of the combined cylinder 9 are the same, thus achieving synchronous rising and falling.

[0032] A threaded disc 17 is rotatably connected to the bottom of the combined cylinder 9. A guide groove 18 is provided below the combined cylinder 9. A guide block 19 is slidably connected inside the guide groove 18 and threadedly connected to the threaded disc 17. After sliding out of the guide groove 18, the guide block 19 contacts the main line 4. A planar thread is provided on the top of the threaded disc 17, and the guide block 19 is threadedly connected to the threaded disc 17 through the planar thread, which is the three-jaw chuck structure in the prior art. The cross-section of the guide block 19 is an L-shaped block structure, and the guide groove 18 is an L-shaped groove structure. The main line 4 can be clamped by the setting of the guide block 19.

[0033] A combination rod 20 is fixedly connected to the top of the threaded disc 17. A through hole 21, adapted to the combination rod 20, is provided between the top and bottom of the second nut 16, and the combination rod 20 is slidably connected inside the through hole 21. The combination of the rod body 11 and the through hole 21 synchronously drives the threaded disc 17 to rotate during the rotation of the second nut 16, that is, the position of the main line 4 can be fixed during the subsequent movement of the second nut 16.

[0034] The locking mechanism includes a locking rod 22 elastically connected inside the slide groove 8. A ball 23 is fixedly connected to the far end of the locking rod 22, and the push block 14 has a trapezoidal cross-section to push the locking rod 22 so that the locking rod 22 contacts the branch line 5. A connecting block is provided below the locking rod 22, and a connecting groove for the connecting block to slide is provided above the slide groove 8. A spring is fixedly connected between one side of the connecting block and the inner wall of the connecting groove. This structure realizes the elastic movement effect of the locking rod 22. That is, when the push block 14 pushes the locking rod 22 to move, the locking rod 22 will first compress the spring to fix its position. When the compression of the locking rod 22 is released, the spring pushes the locking rod 22 to slide out of the slide groove 8.

[0035] The assembly structure includes combination rings 24 fixedly connected to connector 1 and plug 2 respectively. A combination box 25 and a buckle 26 are respectively connected to one side of each combination ring 24. A wedge-shaped block is provided on the side of the buckle 26 away from plug 2. A through groove adapted to the wedge-shaped block is provided on the top of the combination box 25. The wedge-shaped block and through groove enhance the stability of connector 1 and plug 2 after assembly, while the combination rings 24 extend the position of connector 1 and plug 2, preventing interference with their assembly.

[0036] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
