Description

Technical Field

[0001] This utility model relates to the technical field of pin header and female header connectors, specifically a pin header and female header connector with an elastic locking structure. Background Technology

[0002] In the field of electronic equipment, pin headers and female headers are key components for achieving circuit connections and are widely used in various electronic products and industrial equipment. Their reliability directly affects the normal operation of the entire system. As electronic equipment becomes increasingly integrated and its functions become more complex, higher requirements are placed on the connection stability and reliability of pin headers and female headers.

[0003] Most pin header and female header connectors on the market currently use traditional plug-in or snap-fit ​​connection methods. During normal equipment operation, these connectors can meet basic electrical connection requirements. However, when equipment is subjected to bumps and vibrations during handling and transportation, or in long-term vibration environments such as industrial production workshops or vehicle environments, the problem of loose connections gradually becomes apparent. Loose connectors can not only lead to electrical disconnection, causing intermittent equipment failures or complete shutdowns, but can also generate electrical sparks due to poor contact, posing safety hazards and seriously affecting the stability and lifespan of the equipment.

[0004] Because pin header and female header connectors are typically tightly mounted on circuit boards, troubleshooting loose connections is extremely difficult for non-technical personnel. Firstly, the densely packed components and limited space on circuit boards make it difficult to visually detect loose connectors. Secondly, connector repair requires specialized tools and skills, which ordinary users or equipment operators often lack the necessary technical knowledge and experience to perform themselves. They are forced to send the equipment to a professional repair shop, increasing repair costs, extending equipment downtime, and causing significant inconvenience to users. Utility Model Content

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.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

The connector base 1 and the connector plug 2 are mechanically connected through the elastic locking structure 10. The female insertion ports 9 include elastic pin terminals 15, and the electrical pins 4 are inserted into the pin terminals 15. The connector base 1 and the connector plug 2 are electrically connected through the electrical pins 4 and the pin terminals 15.

[0029] Furthermore, the connector plug 2 includes a base 3, multiple sets of electrical pins 4 and a foolproof protrusion 5. Multiple sets of equidistantly arranged electrical pins 4 are provided on one side of the base 3, and a foolproof protrusion 5 is provided on one side of the base 3. Resilient locking grooves 6 are provided on both sides of the base 3 adjacent to the foolproof protrusion 5.

[0030] Furthermore, the connector base 1 has multiple sets of surface mount solder pads 7 on the side opposite to the female connector port 9. Near the female connector port 9, the connector base 1 has a misalignment groove 8 corresponding to the misalignment protrusion 5. The misalignment protrusion 5 and the misalignment groove 8 are connected in an interlocking manner. Both sides of the misalignment groove 8 are provided with elastic locking structures 10. The cooperation between the misalignment protrusion 5 and the misalignment groove 8 prevents incorrect insertion and ensures one-to-one correspondence of signal channels.

[0031] Furthermore, the elastic locking structure 10 includes a steel ball 11, a ball head groove 12, and an elastic silicone cup 13. A ball head groove 12 is formed on the side wall of the connector base 1, and a steel ball 11 is disposed within the ball head groove 12. An elastic silicone cup 13 is disposed on the side of the steel ball 11 away from the center. One end of the elastic silicone cup 13 abuts against the inner wall of the ball head groove 12, and the other end abuts against the steel ball 11. When the connector base 1 and the connector plug 2 are locked together, the side wall of the connector plug 2 abuts against the steel ball 11, and the steel ball 11 retracts into the ball head groove 12. When the connector plug 2 is fully inserted, the steel ball 11 is aligned with the elastic locking groove 6, and the steel ball 11 extends out of the ball head groove 12 and is locked within the elastic locking groove 6. The elastic silicone cup 13 provides elastic drive for the top end of the steel ball 11 to extend out of the ball head groove 12.

[0032] Furthermore, the female connector 9 also includes multiple sets of terminal fixing holes 14. The pin terminal 15 is inserted into the terminal fixing hole 14. The pin terminal 15 includes a left package 16 and a right package 17. The middle of the left package 16 and the right package 17 are provided with a ball protrusion 18. The left package 16 and the right package 17 are both inserted into the terminal fixing hole 14, and the ball protrusion 18 abuts against the inner sidewall of the terminal fixing hole 14. The left package 16 and the right package 17 form a plug hole 19 coaxial with the terminal fixing hole 14. The electrical pin 4 is inserted into the plug hole 19. When electrical connection is made, the electrical pin 4 is inserted into the socket 19. The electrical pin 4 will squeeze the left package 16 and the right package 17. Since the left package 16 and the right package 17 are provided with ball protrusions 18, the inner wall of the socket 19 abuts against the ball protrusions 18, which can cause the ball protrusions 18 to deform slightly. The final result is that the left package 16 and the right package 17 tightly cover the electrical pin 4.

[0033] Furthermore, the left package 16 and the right package 17 are integrated into a terminal base post 20 at the end opposite to the electrical pin 4. The terminal base post 20 is fitted with a crack-resistant sleeve 21 on the outside. The terminal base post 20 is electrically connected to the surface mount solder pad 7.

[0055] Crack-resistant sleeve 21: A structure used to prevent connector terminals from cracking.

[0056] Working Principle: During the connection operation, the connector plug 2 is first aligned with the connector base 1. The anti-misalignment protrusion 5 on the connector plug 2 and the anti-misalignment groove 8 on the connector base 1 cooperate with each other. Since the shape and position of the anti-misalignment protrusion 5 and the anti-misalignment groove 8 are unique, this design can accurately prevent insertion errors and ensure that the signal channels of the connector plug 2 and the connector base 1 correspond one-to-one when inserted, laying the foundation for a stable connection. As the connector plug 2 is inserted into the connector base 1, the elastic locking structure 10 begins to function. The steel ball 11 in the elastic locking structure 10 is located in the ball head groove 12, and one side of it is held in place by the elastic silicone cup 13. As the connector plug 2 gradually approaches the connector base 1, the side wall of the connector plug 2 begins to squeeze the steel ball 11, forcing the steel ball 11 to overcome the elasticity of the elastic silicone cup 13 and retract into the ball head groove 12. When the connector plug 2 is fully inserted, the steel ball 11 aligns perfectly with the elastic locking groove 6 on the connector plug 2. At this point, the elastic silicone cup 13, due to its own elasticity, pushes the steel ball 11 outward, causing part of the steel ball 11 to extend out of the ball head groove 12 and engage with the elastic locking groove 6. This engaging method achieves mechanical locking between the connector base 1 and the connector plug 2, effectively enhancing the stability of the connection. Even under conditions such as handling and vibration, it can prevent relative displacement between the two, ensuring the reliability of the mechanical connection. Simultaneously, the electrical connection is also completed. The electrical pins 4 on the connector plug 2 cooperate with the pin terminals 15 in the female connector 9 on the connector base 1. The pin terminals 15 of the female connector 9 consist of a left sleeve 16 and a right sleeve 17, with a ball protrusion 18 in the middle of both making close contact with the inner wall of the terminal fixing hole 14. When the electrical pin 4 is inserted into the socket 19 formed by the left housing 16 and the right housing 17, the electrical pin 4 will compress the left housing 16 and the right housing 17. Due to the presence of the ball joint 18, the inner wall of the socket 19 exerts a reaction force on the ball joint 18, causing the ball joint 18 to deform slightly. This deformation allows the left housing 16 and the right housing 17 to tightly wrap around the electrical pin 4, achieving a tight and stable electrical contact by utilizing the elasticity of the metal itself. At the same time, the terminal post 20 of the pin terminal 15 is electrically connected to the surface mount solder pad 7 on the connector base 1, further ensuring the integrity of the current transmission path and ensuring the stability and reliability of the electrical connection. In summary, this pin header and female connector with an elastic locking structure ensures accurate insertion through a foolproof structure, achieves a stable mechanical connection through an elastic locking structure, and achieves a reliable electrical connection through specially designed pin terminals. The multi-structure cooperation effectively solves the problems of easy loosening and unstable electrical connection of traditional connectors under vibration, providing a solid guarantee for the stable operation of electronic equipment.
