Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a locking structure for an unlocking button on an energy storage connector. Background Technology

[0002] With continuous innovation in energy storage technology, it has demonstrated tremendous development potential and a wide range of application scenarios. On the user side, energy storage technology can help households, businesses, and industrial enterprises achieve automated self-consumption of electricity and peak-valley electricity price arbitrage, effectively reducing electricity costs and improving energy utilization efficiency. On the power supply side, it can enhance the frequency regulation response capability of thermal power plants and the utilization efficiency of new energy power generation, promoting the optimization and upgrading of the energy structure. On the grid side, energy storage technology can be used for peak shaving, frequency regulation, and backup, enhancing the transmission capacity of regional power grids and ensuring the stable operation of the grid.

[0003] The existing method of using a cantilever with a barb to hold the force has obvious defects. When the male and female terminals are plugged and unplugged too many times or the product ages after a certain number of years, the barb of the unlock button is prone to breakage, causing the unlock button to pop out. With repeated use, the locking mechanism of the connector will fail after the male and female terminals are mated, causing the male and female terminals to separate during operation, resulting in poor electrical contact and even causing safety accidents. Utility Model Content

[0004] To address the issue of the barb on the unlock button easily breaking after repeated use or a certain number of years of product aging, causing the unlock button to pop out, and the locking mechanism between the male and female ends becoming worn out and prone to poor contact, this application provides an unlock button locking structure for an energy storage connector.

[0005] The energy storage connector unlocking button latch structure provided in this application adopts the following technical solution:

[0006] An unlocking button locking structure for an energy storage connector includes a female end body, an unlocking button, and a spring. The female end body has a button slot for placing the unlocking button. The unlocking button has a locking part, a guiding part, and a reset part. The locking part abuts against the inner wall of the button slot, and the guiding part slides against the inner side wall of the button slot. One end of the spring is mounted on the reset part, and the other end of the spring is mounted on the inner wall of the button slot.

[0007] By adopting the above technical solution, the locking part abuts against the key slot to play a locking role. The guide part of the unlocking button slides on the inner wall of the key slot to ensure the stable guidance of the unlocking button. After long-term use and aging, the unlocking button can still be locked into the female end body to ensure good contact, structural stability, and smooth sliding. The reset part of the unlocking button and the inner wall of the key slot form a certain gap, and the reset function of the unlocking button can be realized by pressing the spring.

[0008] Optionally, the locking part includes a cantilever provided on the front and back of the unlock button, and a flexible barb structure provided on the tail of the cantilever, the barb structure abutting against the inner wall of the button groove.

[0009] By adopting the above technical solution, the traditional method of using one cantilevered hook to hold the female end under force, or using two cantilevered hooks at both ends to hold the female end under force, makes the force even when the hook structure abuts against the inner wall of the button groove, doubling the hook holding force. This allows the unlock button to be firmly held in the female end body even in harsh environments and after aging, tightly locking the board end and preventing it from falling off. This avoids safety accidents caused by poor electrical contact due to separation of the male and female ends.

[0010] Optionally, the guide portion includes a groove on the side of the unlock button, and a guide rib is fixed on the inner wall of the button groove, with the guide rib and the groove slidingly engaged.

[0011] By adopting the above technical solution, the unlock button is guided and slidable within the button slot, ensuring the stability and accuracy of the unlock button's movement.

[0012] Optionally, the reset part includes an unlock button with a mounting hole, and the end of the spring is installed in the mounting hole.

[0013] By adopting the above technical solution, the spring is installed together with the unlock button and inserted into the button slot of the female end body. Pressing the spring compresses it to achieve back-and-forth sliding.

[0014] Optionally, the unlock button has a wavy end face on the side away from the spring.

[0015] By adopting the above technical solution, it is convenient for users to operate the unlock button by pressing it, which conforms to the ergonomic principle and makes it easier to control the unlock button to compress the spring and reset.

[0016] Optionally, the unlock button is further provided with a buckle, and a sleeve structure is installed on the female end body, with the buckle and the stepped surface provided on the sleeve structure engaging in a snap-fit ​​relationship.

[0017] By adopting the above technical solution, the latch of the unlock button is engaged with the stepped surface of the sleeve structure, making the male and female ends inseparable and ensuring connection stability. If it is necessary to disassemble, the female end can be pulled out by pressing the unlock button to compress the spring. After releasing, the spring will automatically reset the unlock button.

[0018] Optionally, the unlock button is made of nylon PA66 with glass fiber reinforcement.

[0019] By adopting the above technical solution, the unlock button is made of nylon PA66 with glass fiber, which can meet the requirements of high temperature and low temperature resistance in the application environment of the connector and fully meet the functional requirements.

[0020] Optionally, a guide bevel is formed on the buckle.

[0021] By adopting the above technical solution, the guide beveled surface formed on the buckle can play a guiding role in the mating process of the male and female ends, making the buckle and the stepped surface of the sleeve structure more smoothly connected.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The unlock button is equipped with a cantilever and barb structure on both sides to abut against the inner wall of the button groove, so that the force is evenly distributed and the barb holding force is doubled. This allows the unlock button to be firmly locked into the female end body even in harsh environments and after aging, avoiding separation of the male and female ends during operation, which could lead to poor electrical contact and safety accidents.

[0024] 2. The sliding groove on the side of the unlock button slides into the guide rib on the inner side wall of the button groove, which serves as a guide for installation;

[0025] 3. The unlock button is made of nylon PA66 with glass fiber reinforcement, which meets the requirements of high and low temperature resistance in the application environment of the connector and satisfies the functional requirements. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0033] This application discloses an unlocking button latch structure for an energy storage connector.

[0034] Reference Figure 1 and Figure 4 As shown, the device includes a female end body 1, an unlock button 2, and a spring 3. The unlock button 2 is placed in a button groove 4 opened in the female end body 1. The locking part 21 on the unlock button 2 abuts against the inner wall of the button groove 4, and the guide part 22 slides with the inner side wall of the button groove 4. One end of the spring 3 is installed on the reset part 23 of the unlock button 2, and the other end is installed on the inner wall of the button groove 4, so that the unlock button 2 can be firmly installed in the button groove 4 and can slide flexibly to realize the connection and separation operation of the male end and the female end.

[0035] See Figure 2 and Figure 3 As shown, the locking part 21 includes cantilever 5 on both sides of the unlock button 2. The cantilever 5 serves to support and connect the barbed structure 6. The cantilever 5 typically possesses a certain degree of toughness and strength, and its shape can be elongated, acting like a bridge connecting the unlock button 2 body and the barbed structure 6. The cantilever 5 can be made of the same nylon PA66 reinforced with glass fiber as the unlock button 2. This material has good mechanical properties and can withstand certain external forces without easily deforming. A flexible barbed structure 6 is provided at the tail of the cantilever 5. The barbed structure 6 is a key component for achieving a stable connection between the unlock button 2 and the female end body 1. The barbed structure 6 is shaped like a fishhook, with a curved section that can tightly grip the inner wall of the button slot 4. The elasticity of the barbed structure 6 allows for a certain degree of deformation during installation and disassembly, facilitating installation and unlocking operations. Besides this fishhook-shaped barb, a triangular barbed structure 6 can also be used, as long as it can effectively grip the inner wall of the button slot 4. The barb structure 6 abuts against the inner wall of the button slot 4. When the unlock button 2 is inserted into the button slot 4, the barb structure 6 on both sides simultaneously hooks the inner wall of the button slot 4. Compared with the traditional method where only one cantilever 5 has a barb to hold the force, this embodiment makes the force more even and doubles the barb holding force. This ensures that even after the product ages in harsh environments, the unlock button 2 remains firmly held in the female end body 1, tightly locking the board end and preventing it from falling off, thus avoiding the risk of safety accidents.

[0036] See Figure 2As shown, the guide part 22 includes a groove 7 on the side of the unlock button 2. The groove 7 is a recess extending along the side of the unlock button 2, and its function is to guide the sliding of the unlock button 2. The shape of the groove 7 is usually rectangular, and its width is just enough to accommodate the guide rib 8. The surface of the groove 7 is smooth to reduce the friction between it and the guide rib 8, ensuring smooth sliding of the unlock button 2. In addition to the rectangular groove 7, other shapes such as trapezoidal groove 7 can also be used, as long as the guiding function can be achieved. A guide rib 8 is fixed on the inner side wall of the button groove 4. The guide rib 8 is a raised strip, and its shape and size match the groove 7. The guide rib 8 is integrally formed with the female end body 1 to ensure its firmness. The material of the guide rib 8 can also be the same as that of the female end body 1, which can ensure the consistency and stability of the overall structure. The guide rib 8 and the slide groove 7 slide together. After the unlock button 2 is inserted into the button slot 4, the guide rib 8 is embedded in the slide groove 7. When the unlock button 2 is pressed, the guide rib 8 slides in the slide groove 7, guiding the unlock button 2 to move along the predetermined direction, so as to prevent the unlock button 2 from deviating or getting stuck during the sliding process.

[0037] See Figure 3 As shown, the reset part 23 includes an unlock button 2 with a mounting hole 9. The mounting hole 9 is a circular hole located at a suitable position on the unlock button 2 for mounting the spring 3. The size of the mounting hole 9 is determined according to the outer diameter of the spring 3, and is slightly larger than the outer diameter of the spring 3 to ensure that the spring 3 can be installed smoothly. The depth of the mounting hole 9 should also be appropriate to accommodate a part of the spring 3 to ensure that the spring 3 is installed securely. In addition to the circular mounting hole 9, other shapes such as square mounting holes 9 can also be used. The end of the spring 3 is installed in the mounting hole 9. When the unlock button 2 is pressed, the spring 3 is compressed and stores elastic potential energy; when the unlock button 2 is released, the spring 3 releases the elastic potential energy, pushing the unlock button 2 out and causing it to automatically reset.

[0038] See Figure 3 As shown, a wave-shaped end face is formed on the side of the unlock button 2 away from the spring 3. The design of the wave-shaped end face is mainly to make it easier for the operator to press the unlock button 2. The wave shape can increase the friction between the finger and the unlock button 2, making the pressing operation more comfortable and convenient. The shape and size of the wave are adapted to the finger grip habits of different operators.

[0039] See Figure 3As shown, the unlock button 2 is also equipped with a latch 10. The latch 10 is a protruding structure located on the side of the head of the unlock button 2. The shape of the latch 10 can be rectangular or trapezoidal, etc. Its function is to engage with the stepped surface on the sleeve structure 11. The material of the latch 10 is the same as that of the unlock button 2, and it has a certain strength and toughness. A guide bevel is formed on the latch 10. The function of the bevel is to guide the latch 10 to engage smoothly with the stepped surface on the sleeve structure 11 when the male end and the female end are mated. When the male end and the female end are close, the bevel first contacts the stepped surface. Due to the guiding effect of the bevel, the latch 10 will gradually slide into the step surface to achieve engagement. The sleeve structure 11 is installed on the female end body 1. The sleeve structure 11 is a cylindrical structure that fits over the male end and plays a role in protection and connection. The sleeve structure 11 is provided with a stepped surface, which is an annular plane that engages with the latch 10 to prevent the male end and the female end from separating after mating.

[0040] The unlock button 2 is made of nylon PA66 with glass fiber. Nylon PA66 itself has good mechanical properties, wear resistance and corrosion resistance. After adding glass fiber, its strength, rigidity and heat resistance are further improved, which can meet the requirements of high temperature and low temperature resistance of connector application environment and fully meet the functional use.

[0041] The implementation principle of the unlocking button 2 locking structure of the energy storage connector in this application embodiment is as follows: A cantilever 5 and a barb structure 6 are set on both the front and back sides to make the force more even, increasing the locking force and avoiding the problem of the unlocking button 2 popping out and separating from the male and female ends due to the breakage of a single barb, thus improving the safety and stability of the connector. The sliding groove 7 and guide rib 8 of the guide part 22 cooperate to ensure the smoothness and accuracy of the sliding of the unlocking button 2. The mounting hole 9 of the reset part 23 is fitted with a spring 3, realizing the automatic reset function of the unlocking button 2. The wavy end face facilitates the operator's pressing operation. The snap-fit ​​cooperation between the buckle 10 and the stepped surface of the sleeve structure 11 ensures a stable connection between the male and female ends. At the same time, the use of nylon PA66 with glass fiber material improves the performance and durability of the unlocking button 2, adapting to the complex application environment of the energy storage connector.
