Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an anti-dropping quick-plug connector. Background Art

[0002] Quick-connect connectors are quick-connect and quick-disconnect connectors commonly used in electrical, electronic, automation, liquid transmission and other fields. They allow users to simply and conveniently connect and disassemble different devices or components without using tools or making complicated cable connections.

[0003] However, during use, especially when the connector is pulled, the connector is easily detached from the docking end, resulting in the inability to make a stable electrical connection to the power-connected device, affecting the use of the device. The connector is not stable enough during use. Therefore, we propose an anti-detachment quick-plug connector to solve the existing problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-dropping quick-plug connector, comprising a connector body, a sleeve, a docking end, an insert block, an insert rod and a mounting sleeve, wherein a connecting wire is arranged at one end of the connector body, a docking end is arranged at one side of the connector body, a sleeve is sleeved on the outer side of the docking end, a mounting groove is arranged on the inner wall of the sleeve, an insert block is arranged at the opening of the mounting groove, a spring 1 is arranged on the opposite end of the insert block, a mounting sleeve is sleeved on the outer side of the connector body, travel grooves are arranged inside the upper and lower ends of the mounting sleeve, insert rods are arranged inside the travel grooves, a spring 2 is arranged at one end of the insert rod, a fixing hole penetrating the travel groove is arranged inside the mounting sleeve, and a positioning hole is arranged inside the insert block.

[0006] Preferably, the upper end of the spring 1 is connected to the inner wall of the upper end of the installation slot. The insert block is elastically installed with the installation slot through the spring 1 at the upper end.

[0007] Preferably, a guide block is provided on the inner wall of one side of the travel groove, the lower end of the plug block is located inside the fixing hole, and the four corners of the lower end of the plug block are provided with arc-shaped chamfers. When the plug rod is out of the positioning hole, the connector body pulled outward squeezes the plug block, and the inclined surface of the guide block plays a role in guiding the plug block to help it escape from the travel groove.

[0008] Preferably, a slider is provided at one opposite end of the insertion rod, a slide groove is provided inside the mounting sleeve and is connected to the inside of the travel groove, and the slider is slidably installed inside the slide groove. The slider is slidably installed inside the slide groove and plays a role of sliding guide for the insertion rod.

[0009] Preferably, one end of the insertion rod is slidably inserted into the interior of the positioning hole. When the insertion rod is inserted into the interior of the positioning hole, the insertion block is clamped and fixed.

[0010] Preferably, one end of the second spring is connected to the inner wall of the travel groove, and one end of the insertion rod located outside the fixing sleeve is provided with a pull rod. The insertion rod is elastically mounted inside the travel groove through the elastic support of the second spring.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides a sleeve at the plug-in position of the connector body and the butt end, the sleeve is sleeved on the outside of the plug-in end, and the plug-in block inside the sleeve is plugged into the fixing hole inside the mounting sleeve outside the connector body under the elastic support of spring 1, so as to clamp and fix the connector body. After the plug-in block is plugged and fixed, the plug-in rod is horizontally plugged into the positioning hole to position the plug-in block. The plug-in rod is elastically supported by spring 2 to limit the plug-in block. After the connector body and the sleeve are butt-jointed, a two-way clamping is realized, and the external force pulling process during use prevents the butt end from being separated, and the connector remains stable during use.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, the utility model proposes an anti-dropping quick-plug connector, including a connector body 2, a sleeve 3, a docking end 4, an insert block 7, an insert rod 11 and a mounting sleeve 13. A connecting line 1 is arranged at one end of the connector body 2, a docking end 4 is arranged at one side of the connector body 2, a sleeve 3 is sleeved on the outer side of the docking end 4, a mounting groove 5 is arranged on the inner wall of the sleeve 3, an insert block 7 is arranged at the opening of the mounting groove 5, and a spring 6 is arranged at the opposite end of the insert block 7. The mounting sleeve 13 is sleeved on the outer side of the connector body 2, and travel grooves 9 are arranged inside the upper and lower ends of the mounting sleeve 13, and the travel grooves 9 are arranged inside the insert rods 11, and a spring 15 is arranged at one end of the insert rod 11. A fixing hole 17 penetrating the stroke groove 9 is provided in the part, a positioning hole 8 is provided inside the plug block 7, the upper end of the spring 16 is connected to the inner wall of the upper end of the mounting groove 5, a guide block 10 is provided on the inner wall on one side of the stroke groove 9, the lower end of the plug block 7 is located inside the fixing hole 17, and arc-shaped chamfers are provided at the four corners of the lower end of the plug block 7, a slider 12 is provided at the opposite end of the plug rod 11, a slide groove 14 penetrating the interior of the stroke groove 9 is provided inside the mounting sleeve 13, the slider 12 is slidably installed in the slide groove 14, one end of the plug rod 11 is slidably inserted into the positioning hole 8, one end of the spring 2 15 is connected to the inner wall of the stroke groove 9, and a pull rod 16 is provided at the end of the plug rod 11 located outside the fixing sleeve.

[0021] Implementation steps based on Example 1: The connector body 2 is plugged into the docking end 4 and is located inside the sleeve 3. During the plugging process, the pull rod 16 is forced to the side away from the docking end 4, the spring 15 is squeezed, the plug block 7 is squeezed, and the plug block 7 is retracted into the installation groove 5. After the corresponding fixation, the plug block 7 is elastically supported by the spring 1 6 and plugged into the fixing hole 17. Then the pull rod 16 is sent out. When the spring 15 loses the squeezing force, it pushes the plug rod 11 to be plugged into the positioning hole 8, fixes the plug block 7, and the connector body 2 is bidirectionally clamped and locked. The connector body 2 is prevented from being separated from the docking end 4 under external force, and the connector body 2 is prevented from being separated when the device is connected and used;

[0022] When the connector body 2 is pulled out, the pull rod 16 is pulled outward, driving the insertion rod 11 to move away from the connector, squeezing the spring 15, and the insertion rod 11 moves out of the positioning hole 8. When the insertion rod 11 is out of the positioning hole 8, the connector body 2 that is pulled outward squeezes the insertion block 7, and the inclined surface of the guide block 10 serves as a guide to help the insertion block 7 to disengage from the travel groove 9. Under the action of the squeezing force, the insertion block 7 disengages from the fixing hole 17 and the travel groove 9, and the connector body 2 is separated from the docking end 4, which is stable to use.
