They consist of a pluggable plug and a socket, and securely connect wires, electronic components, and equipment or PCB boards through methods such as wire clamping and soldering. They ensure smooth transmission of current and signals by relying on vibration-resistant design and flexible contact structure, reducing attenuation and interference. They also simplify wiring assembly and disassembly processes, facilitating equipment maintenance, upgrades, and troubleshooting. Furthermore, they mitigate safety hazards such as short circuits and open circuits through insulation protection and locking mechanisms. Widely used in industrial automation, automotive electronics, communication equipment, and home appliances, they are crucial components for ensuring the stable operation of various electrical equipment.

[0003] To address the aforementioned issues, existing patents offer solutions. Most existing plug and terminal assemblies lack anti-detachment structures, which may lead to loosening over time.

[0004] To address this, a plug terminal assembly is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a plug terminal assembly that can solve the problem that most existing plug terminal assemblies lack an anti-loosening structure, which may lead to loosening over time.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plug terminal assembly, including a protective mechanism, wherein a plug structure is fixedly connected inside the protective mechanism, and an auxiliary component is provided on the rear side of the plug structure;

[0007] The protective mechanism includes two adjustment slots, each with a spring fixedly connected inside. An adjustment plate that works with the adjustment slot is fixedly connected to the opposite side of each of the two springs. A limit block is fixedly connected to the opposite side of each of the two adjustment plates. A pressing block is fixedly connected to the opposite side of each of the two adjustment plates. Connecting components are provided on the surface of the two limit blocks.

[0008] Preferably, the auxiliary component includes two plug slots, which are respectively opened at the top and bottom of the plug structure. A plug block is snapped into the inside of each plug slot, and a protective shell is fixedly connected to the rear side of each plug block.

[0009] Preferably, each of the two protective shells has several rubber rings fixedly connected to one side of the opposite side, which are used in conjunction with the plug structure, and the surface of each of the two protective shells is covered with an anti-slip sleeve.

[0010] Preferably, a splicing block is fixedly connected to one side of each of the two plug-in blocks, and a splicing groove is provided on the inner wall of each of the two plug-in slots to cooperate with the splicing block.

[0011] Preferably, the connecting component includes an adhesive strip, a connecting frame is fixedly connected to the rear side of the adhesive strip, and a frame is fixedly connected to the rear side of the connecting frame.

[0012] Preferably, the frame has a limiting groove inside that works with the two limiting blocks, and the top and bottom of the inner wall of the connecting frame have guide grooves.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A plug terminal assembly includes a protective mechanism 1, a plug structure 2 fixedly connected inside the protective mechanism 1, and an auxiliary component 3 disposed on the rear side of the plug structure 2.

[0027] The protective mechanism 1 includes two adjustment slots 101. Springs 102 are fixedly connected inside each of the two adjustment slots 101. Adjustment plates 103 that cooperate with the adjustment slots 101 are fixedly connected to opposite sides of the two springs 102. Limiting blocks 104 are fixedly connected to opposite sides of the two adjustment plates 103. Pressing blocks 105 are fixedly connected to opposite sides of the two adjustment plates 103. Connecting components 106 are provided on the surfaces of the two limiting blocks 104.

[0028] In this embodiment: A protective mechanism 1, a core anti-detachment and protective structure, is provided. Internal components ensure a stable connection between the plug and the connector, preventing loosening. A plug structure 2, a core conductive connection component, enables current and signal transmission between circuits. An auxiliary component 3 provides auxiliary protection and fixation, enhancing the stability and protective properties of the plug structure 2. An adjustment groove 101 provides installation and movement space for the spring 102 and adjustment plate 103, limiting the movement trajectory of the components. The spring 102 provides elastic force, pushing the adjustment plate 103 to move the limiting block. 104 resets to ensure the limit locking effect. By setting the adjustment plate 103, the force of the spring 102 is transmitted to drive the extension and retraction of the limit block 104, realizing the switching between locking and unlocking. By setting the limit block 104 to cooperate with the limit groove 1064, the plug structure 2 and the connecting component 106 are fixed to prevent them from falling off. By setting the pressing block 105, the user can press to drive the adjustment plate 103 and the limit block 104 to move, making it easy to insert and remove the plug. By setting the connecting component 106 to cooperate with the protective mechanism 1, a stable connection between the plug structure 2 and the outside is achieved, providing an installation benchmark.

[0029] Specifically, such as Figure 4 As shown, the auxiliary component 3 includes two plug slots 301, which are respectively opened at the top and bottom of the plug structure 2. A plug block 302 is snapped into the inside of each plug slot 301, and a protective shell 303 is fixedly connected to the rear side of each plug block 302.

[0030] Specifically, such as Figure 4 As shown, several rubber rings 304 that cooperate with the plug structure 2 are fixedly connected to the opposite side of the two protective shells 303, and anti-slip sleeves 305 are fitted on the surface of the two protective shells 303.

[0031] Specifically, such as Figure 4 As shown, each of the two plug-in blocks 302 has a splicing block 306 fixedly connected to one side of its opposite side, and the inner walls of the two plug-in slots 301 are provided with splicing slots 307 that cooperate with the splicing blocks 306.

[0032] In this embodiment: by providing a plug groove 301 for the plug block 302 to snap into, a detachable connection between the protective shell 303 and the plug structure 2 is achieved. By providing a plug block 302 to cooperate with the plug groove 301, the position of the protective shell 303 is fixed, ensuring the installation stability of the protective shell 303. By providing a protective shell 303, the rear side of the plug structure 2 is protected, reducing the impact of external dust and collisions on the components. By providing a rubber ring 304, the fit and sealing between the protective shell 303 and the plug structure 2 are enhanced, while also playing a role in buffering and vibration reduction. By providing an anti-slip sleeve 305, the surface friction of the protective shell 303 is increased, making it easier to hold during plugging and unplugging operations and improving ease of use. By providing a splicing block 306 and a splicing groove 307, the inner walls of the splicing block 306 and the splicing groove 307 are snapped together, facilitating the splicing of the two protective shells 303 and the plug structure 2, improving installation stability. Furthermore, since the two protective shells 303 are snapped together, the auxiliary component 3 can protect the connection lines of the plug structure 2.

[0033] Specifically, such as Figure 2 As shown, the connecting component 106 includes an adhesive strip 1061, a connecting frame 1062 is fixedly connected to the rear side of the adhesive strip 1061, and a frame 1063 is fixedly connected to the rear side of the connecting frame 1062.

[0034] Specifically, such as Figure 2 As shown, the frame 1063 has a limiting groove 1064 inside that works with the two limiting blocks 104, and the connecting frame 1062 has guide grooves 1065 at the top and bottom of its inner wall.

[0035] In this embodiment: an adhesive strip 1061 is provided to fix the connecting frame 1062 and related components, enhancing connection stability; the connecting frame 1062 connects the adhesive strip 1061 and the frame 1063, providing guidance and installation support; the inner wall guide groove 1065 assists in positioning the limiting block 104; the frame 1063 connects the external support structure of the connecting component 106, and the internal limiting groove 1064 is provided for the limiting block 104 to engage; the limiting groove 1064 cooperates with the limiting block 104 to form a locking structure, preventing the plug from loosening and falling off; the guide groove 1065 guides the movement of the limiting block 104, ensuring the accuracy of engagement.

[0036] Specifically, such as Figure 4 As shown, buffer pads 4 are fixedly connected to the rear side of both limit blocks 104, and the material of both buffer pads 4 is insulating rubber.

[0037] Specifically, such as Figure 5 As shown, sliding grooves 5 are provided at the top and bottom of the inner wall of the adjusting groove 101, and sliding blocks 6 that cooperate with the sliding grooves 5 are fixedly connected to the top and bottom of the adjusting plate 103.

[0038] In this embodiment: by setting a buffer pad 4, which is made of insulating rubber, the collision and wear between the limit block 104 and the frame 1063 are reduced, and at the same time, it plays an insulating and protective role. By setting a sliding groove 5 and a sliding block 6, the sliding block 6 and the sliding groove 5 are internally slidably connected, which helps the adjustment plate 103 to move smoothly and avoids the adjustment plate 103 from deviating and getting stuck.

[0039] Working principle: In use, first fix the connecting component 106 to the corresponding installation position using the adhesive strip 1061. Press the pressing blocks 105 on both sides to drive the adjusting plate 103 to move along the matching trajectory of the sliding groove 5 and the sliding block 6 in the adjusting groove 101, compressing the spring 102 and causing the limiting block 104 to retract. Then, insert the plug structure 2 into the connecting frame 1062 and the frame 1063. After releasing the pressing blocks 105, the spring 102 returns to its original position and pushes the adjusting plate 103, so that the limiting block 104 is accurately engaged in the frame. The locking mechanism is completed in the limiting groove 1064 of the frame 1063. At the same time, the plug block 302 in the auxiliary component 3 is engaged with the plug groove 301 of the plug structure 2 to fix the protective shell 303. The inner rubber ring 304 enhances the sealing and buffering, and the outer anti-slip sleeve 305 facilitates gripping. The insulating rubber buffer pad 4 on the rear side of the limiting block 104 reduces collision wear. Through the dual functions of limiting locking and auxiliary protection, the plug structure 2 is stably connected, avoiding loosening after long-term use and ensuring smooth transmission of current and signal.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
