Description

Technical Field

[0001] This utility model is a terminal mating structure, belonging to the field of electrical connection equipment. Background Technology

[0002] In the field of electronic equipment manufacturing, terminals are key components for achieving electrical connections. The stability and reliability of their mating structure have always been a focus of industry attention. Early terminal mating structures were usually designed simply, relying on a single snap-fit ​​or plug-in method for connection. For example, some terminals were simply inserted into the plastic core slot without any additional fixing measures.

[0003] In existing technologies, during equipment operation, even slight vibrations, impacts, or external pulling can easily cause terminals to detach from their slots, leading to electrical connection interruptions and equipment malfunction. This can have serious consequences in electronic devices with extremely high stability requirements, such as aerospace and medical electronic equipment. Furthermore, the performance of traditional terminal mating structures is significantly affected by different operating environments. In high-temperature, humid, or corrosive environments, connecting components are prone to deformation and corrosion, resulting in loose connections. Moreover, when equipment vibrates during operation, the lack of effective cushioning and anti-slip design can cause the connection between the terminal and the core to gradually loosen, affecting the reliability of the electrical connection.

[0004] In summary, this utility model provides a terminal mating structure to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a terminal mating structure to solve the problem mentioned in the background art that the connection stability between the terminal and the core will decrease with the extension of the service time.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a terminal mating structure, including a front end shell and a rear end shell of a rubber core, wherein two barbed clips are provided on one side of the front end shell by casting, and a slot for engaging the two barbed clips is provided on the side of the rear end shell near the front end shell. One side of the front end shell is embedded into the interior of the rear end shell, and two connecting slots are provided inside the rear end shell. Two terminal bodies are embedded on the other side of the rear end shell through the two connecting slots, and two terminal seat back shells are embedded on the other side of the front end shell. One end of the terminal body penetrates one end of the terminal seat back shell and extends into the interior of the terminal seat back shell.

[0007] Furthermore, the front end shell of the rubber core is engaged with the rear end shell of the rubber core through two barbed clips and a slot.

[0008] Furthermore, the two barbed clips are mirror-symmetrical, and both ends are barbed, and the two barbed clips are distributed in a figure-eight shape.

[0009] Furthermore, a stop ring is fixedly sleeved inside the rear shell of the terminal base and outside the terminal body. A retaining ring is fixedly sleeved on both sides of the outer surface of the terminal body and between the two opposite sides of the stop ring. A groove is opened between the stop ring and the inner wall of the rear shell of the terminal base to fit the retaining ring. The rear shell of the terminal base and the terminal body are interlocked by the two retaining rings and the two stop rings.

[0010] Furthermore, a snap-fit ​​barb is provided on the outside of the terminal body and inside the connecting groove, and a groove is provided on the inner wall of the connecting groove to fit the snap-fit ​​barb, and an elastic rubber pad is fixedly adhered to the inner wall of the groove.

[0011] Furthermore, the buckle barb on the side away from the terminal body has anti-slip texture, which is wavy.

[0012] Furthermore, a core retaining position is provided on the side of the terminal body surface away from the snap barb, and a limiting protrusion is provided on one side of the inner wall of the connecting groove, which is interlocked with the core retaining position.

[0013] The beneficial effects of this utility model are:

[0014] The combination of snap-fit ​​barbs and grooves on the inner wall of the connecting slot, along with the design of elastic pads and anti-slip textures, ensures that the terminal body is firmly fixed within the connecting slot. The elastic pads fill gaps, provide friction and cushioning, while the anti-slip textures increase friction, all working together to prevent the terminal body from loosening, rotating, or sliding. This ensures the stable position of the terminal within the outer shell at the rear end of the core, making its fit with the core slot tighter and preventing the terminal from accidentally coming out.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-7This utility model provides a technical solution: a terminal mating structure, including a front end shell 1 and a rear end shell 2 of a rubber core. Two barbed clips 3 are cast onto one side of the front end shell 1. A slot 4 for engaging the two barbed clips 3 is provided on the side of the rear end shell 2 near the front end shell 1. One side of the front end shell 1 is embedded into the interior of the rear end shell 2. Two connecting slots 5 are provided inside the rear end shell 2. Two terminal bodies 6 are embedded on the other side of the rear end shell 2 through the two connecting slots 5. Two terminal base shells 12 are embedded on the other side of the front end shell 1. One end of each terminal body 6 penetrates one end of a terminal base shell 12 and extends into the interior of the terminal base shell 12. The front end shell 1 and the rear end shell 2 together constitute a support and protection structure for the terminal body 6, ensuring the terminal operates smoothly. To ensure stability during the process, the front shell 1 of the rubber core is engaged with the rear shell 2 of the rubber core through two barbed clips 3 and a slot 4. The two barbed clips 3 are mirror-symmetrical and have barbed ends. The two barbed clips 3 are distributed in a figure-eight shape. The figure-eight shape design makes it easier for the barbed clips 3 to align with the slot 4 when installing the front shell 1 and the rear shell 2 of the rubber core. At the same time, the outward shape provides greater friction and stability after engagement, preventing the front shell 1 and the rear shell 2 of the rubber core from easily separating. The barbed ends further enhance the reliability of the engagement, making the connection between the two tighter and less likely to fall off even under certain external pulling force. The front shell 1, the rear shell 2, the terminal body 6, and the rear shell 12 of the terminal base are made of high-strength, high-insulation polycarbonate through injection molding.

[0026] Please see Figure 2 and Figure 7 Both the interior of the terminal housing 12 and the exterior of the terminal body 6 are fixedly fitted with stop rings 13. Both sides of the outer surface of the terminal body 6 and between the opposite sides of the two stop rings 13 are fixedly fitted with retaining rings 14. The stop rings 13 and the inner wall of the terminal housing 12 are provided with grooves for the retaining rings 14 to be fitted. The terminal housing 12 and the terminal body 6 are engaged with each other by the two retaining rings 14 and the two stop rings 13. This engagement method not only restricts the axial movement of the terminal body 6 in the terminal housing 12, but also prevents its radial wobbling, ensuring the precise fit between the terminal body 6 and the terminal housing 12, and improving the stability and reliability of the entire terminal engagement structure.

[0027] Please see Figure 2-6A snap-fit ​​barb 7 is provided on the outside of the terminal body 6 and inside the connecting groove 5. The inner wall of the connecting groove 5 has a groove that fits into the snap-fit ​​barb 7, and an elastic rubber pad 9 is fixedly adhered to the inner wall of the groove. The side of the snap-fit ​​barb 7 away from the terminal body 6 has an anti-slip texture 8, which is wavy. The design of the snap-fit ​​barb 7 allows the terminal body 6 to be firmly fixed in the connecting groove 5, preventing its axial movement. The presence of the elastic rubber pad 9 further enhances the stability of the connection. It can fill the gap between the snap-fit ​​barb 7 and the groove, providing additional friction and cushioning, reducing the loosening of the terminal body 6 due to vibration or external force. In addition, the wavy anti-slip texture 8 increases the friction between the snap-fit ​​barb 7 and the inner wall of the groove, making the connection more stable and effectively preventing the terminal body 6 from rotating or sliding in the connecting groove 5.

[0028] Please see Figure 2-6 A core retainer 11 is provided on the side of the terminal body 6 away from the snap barb 7. A limiting protrusion 10 is provided on one side of the inner wall of the connecting groove 5, which is interlocked with the core retainer 11. The cooperation between the core retainer 11 and the limiting protrusion 10 further enhances the stability of the terminal body 6 in the outer shell 2 at the rear end of the core, prevents it from shifting during operation, and ensures the reliability of the electrical connection.

[0029] Specific implementation method: During installation, the operator aligns the front end shell 1 of the glue core with the rear end shell 2 of the glue core. Since the two barbed clips 3 on one side of the front end shell 1 of the glue core are distributed in a figure-eight shape, the barbed clips 3 can be easily aligned with the slots 4 on the rear end shell 2 of the glue core. When the two are close together and a certain pressure is applied, the barbed clips 3 gradually enter the slots 4 due to their elasticity.

[0030] The barbed design at the end of the barbed clip 3 plays a key role after it is inserted into the slot 4. The barb tightly grips the inner wall of the slot 4, forming a firm connection. At the same time, the outward-expanding V-shape provides a larger contact area after the clip is engaged, thereby generating greater friction and preventing the front shell 1 and the rear shell 2 of the core from easily separating when subjected to external pulling or vibration. This ensures the stability and reliability of the connection between the two. This connection method provides a stable support and protection structure for the internal terminal body 6.

[0031] One end of the terminal body 6 needs to be inserted into the terminal base back shell 12. Inside the terminal base back shell 12, a stop ring 13 is fixedly sleeved on the outside of the terminal body 6, and retaining rings 14 are fixedly sleeved on the corresponding positions on both sides of the outer surface of the terminal body 6. A groove is provided between the stop ring 13 and the inner wall of the terminal base back shell 12 to fit the retaining ring 14.

[0032] When the terminal body 6 is inserted into the rear shell 12 of the terminal block, the retaining ring 14 will be embedded in the corresponding groove. This snap-fit ​​method effectively restricts the axial movement of the terminal body 6 within the rear shell 12 of the terminal block, that is, it prevents the terminal body 6 from sliding back and forth. At the same time, it also avoids the terminal body 6 from wobbling radially, ensuring the precise fit between the terminal body 6 and the rear shell 12 of the terminal block, thereby improving the stability and reliability of the entire terminal fit structure.

[0033] When the terminal body 6 is inserted into the connecting groove 5 of the outer shell 2 at the rear end of the core, the snap-fit ​​barbs 7 on the outside of the terminal body 6 will engage with the grooves on the inner wall of the connecting groove 5. The snap-fit ​​barbs 7 play a primary role in fixing the terminal body 6 and preventing axial movement within the connecting groove 5. The elastic rubber pads 9, which are fixedly adhered to the inner wall of the groove, further enhance the stability of the connection. They not only fill any gaps that may exist between the snap-fit ​​barbs 7 and the groove, but also provide additional friction and act as a buffer when subjected to vibration or external impact, reducing the possibility of the terminal body 6 loosening. In addition, the wavy anti-slip texture 8 on the snap-fit ​​barbs 7 increases the friction with the inner wall of the groove, making the terminal body 6 more stable within the connecting groove 5 and effectively preventing it from rotating or sliding.

[0034] A core retainer 11 is provided on the side of the terminal body 6 away from the snap barb 7, and a limiting protrusion 10 is provided on one side of the inner wall of the connecting groove 5. When the terminal body 6 is inserted into the connecting groove 5, the core retainer 11 and the limiting protrusion 10 are accurately engaged. This engagement method further enhances the stability of the terminal body 6 in the outer shell 2 at the rear end of the core, and limits the terminal body 6 from another direction to prevent unnecessary displacement during operation, thereby ensuring the reliability of the electrical connection and ensuring that the entire terminal engagement structure can stably transmit current or signals.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
