Description
Technical Field
[0001] This utility model relates to the field of terminal wire technology, and in particular to terminal wires with a quick-plug interface structure. Background Technology
[0002] Terminal wires are electronic wire harness assemblies composed of terminals and wires. Circuit connections are achieved by crimping or soldering terminals to both ends of the wires. They are widely used in electronic equipment, home appliances, automobiles and other fields to transmit current or signals.
[0003] Terminal wires with quick-plug interface structures are wire harnesses equipped with convenient connection components that enable quick connection or disconnection between terminals and devices. Circuit conduction or disconnection is achieved through the locking and releasing of the interface's mechanical structure. They are characterized by high connection efficiency, simple operation, and reliable electrical connection.
[0004] In existing technologies, some terminal wires are typically connected using screws, which require tools for installation and removal, resulting in lengthy operations and making it difficult to meet the needs of high-frequency maintenance or rapid replacement scenarios. While snap-fit structures do not require tools, precise alignment is required during insertion and removal. In dynamic environments such as vibration and impact, screws can easily loosen, leading to circuit breakage or signal interruption, posing a safety hazard, especially in industrial equipment and automotive electronics. Therefore, a terminal wire with a quick-plug interface structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a terminal wire with a quick-plug interface structure, which aims to improve the problem that screws are prone to loosening in the prior art, causing circuit disconnection or signal interruption.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A terminal wire with a quick-plug interface structure includes a carrier. The carrier has two driven slots inside. A spring is fixedly connected to the rear inner wall of the driven slot. A driven block is fixedly connected to the front side of the spring. A toggle block is fixedly connected to the far side of the two driven blocks. The carrier has two linkage slots inside. A connecting post is slidably connected inside the linkage slot. A spring is sleeved on the outside of the connecting post. A linkage block is fixedly connected to the near side of the two springs. The carrier has multiple portable components inside.
[0008] As a further description of the above technical solution:
[0009] The portable component includes multiple connecting slots, with multiple springs fixedly connected to the top inner wall of the connecting slots, and a folding strap fixedly connected to the bottom of the multiple springs. A connecting block is fixedly connected to the bottom of the folding strap, and two connecting slots are formed inside the connecting block.
[0010] As a further description of the above technical solution:
[0011] Two springs are fixedly connected to the adjacent sides of the two connecting grooves, and connecting posts are fixedly connected to the distant sides of the two springs. Multiple limiting blocks are fixedly connected to the rear side of the carrier, and a moving block is fixedly connected to the bottom of the connecting block.
[0012] As a further description of the above technical solution:
[0013] The driven block is externally slidably connected to the inside of the driven slot, and the left side of one of the linked blocks and the right side of one of the driven blocks are in contact;
[0014] As a further description of the above technical solution:
[0015] The left side of one of the springs is fixedly connected to the left inner wall of one of the linkage grooves, and the right side of one of the springs is fixedly connected to the right inner wall of the connecting column.
[0016] As a further description of the above technical solution:
[0017] The carrier has multiple connection ports inside, and an end wire is fixedly connected to the rear side of the carrier;
[0018] As a further description of the above technical solution:
[0019] The outer side of the folded strip is slidably connected to the inside of the connecting groove, and the outer side of the connecting post is slidably connected to the inside of the connecting groove;
[0020] As a further description of the above technical solution:
[0021] The inner wall of the limiting block is in contact with the outer side of the connecting column, and the outer sides of the plurality of connecting grooves are respectively opened inside the carrier.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by inserting the carrier into the external device, the inner wall of the external device squeezes the connecting column to retract it, which in turn drives the connecting column to squeeze the second spring. At the same time, the linkage block applies pressure to the driven block, causing the driven block to compress the first spring. Through the elastic reset of the first and second springs, the connecting column is driven to be inserted into the external device. By moving the push block backward, the driven block is driven to squeeze the first spring, releasing the compression of the linkage block. Then, the second spring pulls the connecting column to reset, thereby realizing automatic locking when the port is inserted and quick unlocking and separation when it is pulled out. This greatly improves the terminal wire connection efficiency. The mechanical linkage design ensures stable and reliable connection and effectively avoids the shaking or poor contact problems of traditional plugging and unplugging methods.
[0024] 2. In this utility model, by pulling the moving block, the folding strip is extended and retracted through the connecting block, while the spring three is stretched. Then, the connecting post is squeezed out by the inner wall of the connecting end and reset by the elastic action of the spring four, causing the connecting post to be inserted into the limiting block, thus completing the limiting and fixing of the folding strip. By pulling the moving block downward, the connecting post is disengaged from the limiting block, and then the connecting posts on both sides are pressed simultaneously, allowing the folding strip to be reset normally by the spring three. This achieves the blocking and quick opening of the unused connecting end, effectively preventing dust and dirt. Pulling the moving block and pressing the connecting post can quickly reset the folding strip without affecting the normal use of the terminal wire, combining practicality and convenience.

[0032] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a terminal wire with a quick-plug interface structure, including a carrier 1, which is a port for connecting to an external device. The carrier 1 has two driven grooves 2 inside, which provide fixation and support for a spring 3. The spring 3 is fixedly connected to the inner wall of the rear side of the driven groove 2. The spring 3 has an elastic function and provides elastic support for its driven block 4. The driven block 4 is fixedly connected to the front side of the spring 3. The driven block 4 is compressed by the elastic support from the spring 3. The two driven blocks 4 are respectively fixedly connected to the opposite side of the two driven blocks 4. The driven block 5 is used to move the driven block 9 backward when it needs to release the compression of the driven block 9, thereby driving the driven block 4 to compress the spring 3 and then release the compression of the driven block 9. The carrier 1 has two linkage grooves 6 inside, which provide limiting and guiding functions for the connecting post 7.
[0034] The connecting groove 6 has a sliding connection of a connecting post 7. When the connecting block 9 is pressed, the connecting post 7 is driven to engage with the interior of the external device, thereby fixing the carrier 1. The connecting post 7 is fitted with a second spring 8, which has an elastic function and provides elastic support for the connecting post 7. The two springs 8 are fixedly connected to the adjacent sides of each other. After the connecting block 9 is squeezed away by the driven block 4, the elastic reset of the second spring 8 pulls the connecting post 7 to reset and disengage it from the interior of the external device, so that the port can be removed. At the same time, when connecting to the external device, the connecting post 7 is squeezed by the external device and retracts, squeezing the second spring 8. Meanwhile, the connecting block 9 squeezes the driven block 4, which in turn squeezes the first spring 3. When the carrier 1 moves to the appropriate position, the elastic reset of the first spring 3 and the second spring 8 resets the mounting components, thereby locking the connecting post 7 into the interior of the external device, thus fixing the carrier 1. The interior of the carrier 1 has multiple portable components.
[0035] Reference Figure 4 and Figure 5 The portable component includes multiple connecting slots 10, which provide fixation and support for springs 11. Multiple springs 11 are fixedly connected to the top inner wall of the connecting slot 10. Springs 11 have an elastic function and provide elastic support for their folding straps 12. Folding straps 12 are fixedly connected to the bottom of the multiple springs 11. Folding straps 12 provide fixation and support for the connecting block 13 below. Connecting block 13 is fixedly connected to the bottom of folding strap 12. Connecting block 13 provides space for connecting slots 14. Two connecting slots 14 are opened inside the connecting block 13. Connecting slots 14 provide fixation and support for springs 15. Springs 15 are fixedly connected to the adjacent side of the two connecting slots 14 respectively. Springs 15 have an elastic function and provide elastic support for their connecting posts 16.
[0036] Two springs 15 are respectively fixedly connected to connecting posts 16 on opposite sides. The connecting posts 16 are used to receive elastic support from the springs 15 and are locked in the inner wall of the limiting block 17, thereby limiting and fixing the folding belt 12, so as to cover the unused connecting end and prevent dust from entering. Multiple limiting blocks 17 are fixedly connected to the rear side of the carrier 1. The limiting blocks 17 are used to limit the connecting posts 16, thereby limiting the folding belt 12. The bottom of the connecting block 13 is fixedly connected to a moving block 18. The operator pulls the moving block 18, thereby driving the folding belt 12 to extend and retract through the connecting block 13, while stretching the spring 11. At the same time, the connecting posts 16 are squeezed out by the inner wall of the connecting end and reset by the elastic action of the springs 15. When the moving block 18 moves to the appropriate position, the connecting posts 16 are locked into the interior of the limiting block 17, thereby completing the limiting and fixing of the folding belt 12.
[0037] Reference Figure 1 , Figure 2 and Figure 4 The driven block 4 is externally slidably connected to the inside of the driven groove 2. The driven groove 2 provides limiting and guiding functions for the driven block 4. The left side of one of the linkage blocks 9 and the right side of one of the driven blocks 4 are in contact. The driven block 4 receives elastic support from the spring 3 to compress the linkage block 9. The left side of one of the springs 8 is fixedly connected to the left inner wall of one of the linkage grooves 6. The linkage groove 6 provides fixing and supporting functions for the spring 8. The right side of one of the springs 8 is fixedly connected to the right inner wall of the connecting column 7. The spring 8 provides elastic support for the connecting column 7. The carrier 1 has multiple connection ports 19 inside. The connection ports 19 are used to connect to external ports for data transmission. The rear side of the carrier 1 is fixedly connected to the end line 20. The end line 20 is used for data transmission. The folding belt 12 is externally slidably connected to the inside of the connecting groove 10. The connecting groove 10 provides limiting and guiding functions for the folding belt 12.
[0038] The external of the connecting post 16 is slidably connected to the inside of the connecting groove 14. The connecting groove 14 provides a limiting and guiding function for the connecting post 16. The inner wall of the limiting block 17 is in contact with the external of the connecting post 16. The connecting post 16 is used to be inserted into the inner wall of the limiting block 17, thereby limiting and fixing the folding strip 12. The external of the multiple connecting grooves 10 is respectively opened inside the carrier 1. The carrier 1 provides a limiting and guiding function for the connecting grooves 10.
[0039] Working principle: When the port is inserted into an external device, the carrier 1 is inserted into the external device, and the inner wall of the external device presses the connecting post 7 to retract it. This causes the connecting post 7 to press the second spring 8. At the same time, the linkage block 9 applies pressure to the driven block 4, causing the driven block 4 to compress the first spring 3. When the carrier 1 moves to the appropriate position, the first spring 3 and the second spring 8 elastically reset, causing the connecting post 7 to be inserted into the external device, thus completing the limiting and fixing of the carrier 1 and achieving quick connection. When it is necessary to pull out the carrier 1, the pusher block 5 is moved backward, causing the driven block 4 to press the first spring 3, releasing the pressure on the linkage block 9. Then, the second spring 8 pulls the connecting post 7 to reset, disengaging it from the external device and achieving quick separation.
[0040] When the unused connecting end needs to be covered, the operator pulls the shift block 18, which in turn causes the folding strip 12 to extend or retract via the connecting block 13. At the same time, the spring 11 is stretched, and the connecting post 16 is squeezed out by the inner wall of the connecting end. It then resets due to the elasticity of the spring 15. When the shift block 18 moves to the appropriate position, it causes the connecting post 16 to engage inside the limiting block 17, thus fixing the folding strip 12 and covering the unused connecting end to prevent dust from entering. When the connecting end needs to be used, the operator pulls the shift block 18 downward to disengage the connecting post 16 from inside the limiting block 17. Then, the connecting posts 16 on both sides are pressed simultaneously, allowing the folding strip 12 to reset normally via the spring 11.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
