Description

Technical Field

[0002] Connectors, as core components for inter-module connections in electronic devices, have faced the technical challenge of environmental adaptability since their invention in the late 19th century. Traditional connectors employ a combination of contact conductors and plastic shells, using plastic to fix the terminals and achieve insulation. However, this is prone to poor contact under complex operating conditions such as vibration and temperature and humidity changes. With the increasing demand for product lifespans exceeding 8 years in fields such as new energy vehicles and power grid equipment, problems such as terminal displacement and solder joint breakage due to insufficient mechanical strength of conventional plastic shells are becoming increasingly prominent, seriously affecting the reliability of equipment operation.

[0003] While existing technologies aim to improve connection stability by optimizing terminal structures or adding auxiliary positioning components, these methods are mostly limited to single-directional limiting designs and struggle to withstand multi-axis vibration and impact. Some solutions employ increased plastic wall thickness to enhance structural strength, but this leads to difficulties in injection molding and increased costs. Furthermore, welding positioning relies on direct contact between the plastic component and the PCB board, which is prone to deformation under thermal stress, resulting in defects such as cold solder joints and solder bleed, becoming a technical bottleneck restricting the long-term reliability of connectors.

[0037] According to an embodiment of the present invention, a connector with a metal clip plate is provided on a specific embodiment of the metal clip 29, wherein the metal clip 29 is provided with a metal clip tin-blocking plate 35 and a metal clip welding area 36, ​​and the metal clip tin-blocking plate 35 and the metal clip welding area 36 form a bent structure.

[0038] According to an embodiment of the present invention, a connector with a metal card plate is provided. In a specific embodiment, the core 16 is provided with a core guide chamfer 21, which is located at the entrance of the core terminal socket 23.

[0039] According to an embodiment of the present invention, a connector with a metal clip plate is provided. In a specific embodiment, the core 16 is provided with a core metal clip hook limiting rib 25, and the core metal clip hook limiting rib 25 and the metal clip hook limiting plane 30 on the metal clip 29 form a planar contact limiting structure.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0041] This case relates to a connector with a metal clip plate. The connector and the PCB are pre-positioned by the metal clip hook 29 on the metal clip plate. Then, the metal clip welding area 36 on the metal clip hook 29 is welded, which makes the connection between the connector and the PCB more reliable. Even if the plug of the connector is vibrated, it will not affect the overall strength of the connection between the connector and the PCB, thereby improving the contact quality and installation strength of the connector.

[0042] In practical use, the connector with a metal clip according to this utility model includes a core 16, a metal hook 29, a terminal 6, and a cover 1. First, the terminal 6 is inserted into the corresponding core terminal socket 23. To facilitate the insertion of the terminal 6 into the corresponding core terminal socket 23, the core 16 is designed with a core guide chamfer 21. After the terminal 6 is inserted, the first terminal limiting plane 7 and the second terminal limiting plane 8 contact the first core terminal limiting plane 18 and the second core terminal limiting plane 19, respectively. After contact, the terminal 6 is restricted from moving forward, thereby ensuring the fixed position of the terminal 6.

[0043] To further improve the stability of terminal 6 within the core terminal socket 23, terminal limiting wings 9 are designed on terminal 6. These terminal limiting wings 9 are inserted into the core terminal limiting groove 26, which can restrict the left and right movement of terminal 6, thereby improving the positional accuracy of terminal 6 within the core terminal socket 23.

[0044] To improve the reliability of the contact between the plug and the connector, the contact area on terminal 6 is designed with six surfaces: a first terminal contact surface 12, a second terminal contact surface 13, a third terminal contact surface 14, a fourth terminal contact surface, a fifth terminal contact surface 15, and a sixth terminal contact surface. The opposite side of the third terminal contact surface 14 is the corresponding fourth terminal contact surface, and the opposite side of the fifth terminal contact surface 15 is the corresponding sixth terminal contact surface. These six surfaces tightly wrap around the plug terminals.

[0045] After the terminal 6 and the core 16 are assembled, the core 1 passes through the hot-melt hole 3 of the cover and the hot-melt column 20 of the core. After passing through, the plastic on the cover 6 and the hot-melt rib 2 of the core 16 is melted by the heating fixture. After melting, when the product cools down, the cover 1 and the core 16 will be tightly bonded together by the excess glue after the hot melt, so as to achieve the purpose of preventing the cover 1 from falling off the core 16.

[0046] To further improve the directional accuracy of the assembly of the cover 1 and the core 16, the core 16 is also designed with a core anti-misalignment block 22, and the cover 1 is designed with a cover anti-misalignment groove 4. Under the action of the cover anti-misalignment groove 4 and the core anti-misalignment block 22, the cover 1 cannot be assembled into the core 16 in reverse, thus ensuring the correctness of the assembly of the cover 1.

[0047] To improve the position accuracy of the terminal pin tail, the cover 1 is also designed with a cover terminal pin tail positioning hole 5. After the terminal pin tail passes through the cover terminal pin tail positioning hole 5, the cover terminal pin tail positioning hole 5 on the cover 6 can restrict the left and right movement of the terminal pin tail, thereby ensuring that the terminal pin tail will not be skewed.

[0048] In addition, to improve the overall strength of the core 16, a core reinforcing arm 17 is designed on the side of the core 16. Under the action of the core reinforcing arm 17, the strength of the core 16 can be guaranteed and the deformation of the core 16 can be reduced.

[0049] After the cover 1 is assembled, the metal hook 29 is assembled into the corresponding rubber core metal hook groove 24. The first metal hook limiting surface 31 and the second metal hook limiting surface 32 are inserted into the first rubber core metal hook limiting groove 27 and the second rubber core metal hook limiting groove 28, respectively. At this time, the metal hook limiting plane 30 and the rubber core metal hook limiting rib 25 come into contact, and the limiting and assembly of the metal hook 29 is completed.

[0050] To ensure the holding force between the metal hook 29 and the rubber core 16, the metal hook 29 is designed with a first metal hook locking point 33 and a second metal hook locking point 34. The first metal hook locking point 33 and the second metal hook locking point 34 are respectively in an interference fit with the first rubber core metal hook limiting groove 27 and the second rubber core metal hook limiting groove 28. Under the interference fit, a holding force will be formed between the metal hook 29 and the rubber core 16, thereby ensuring that the metal hook 29 will not fall off the rubber core 16.

[0051] To further enhance the assembly strength between the product and the PCB board, the metal hook 29 is also designed with a metal hook welding area 36. This metal hook welding area 36 passes through the hole in the PCB board and is then welded to it. After welding, the metal hook welding area 36 will become a whole with the PCB board. If the product is subjected to external impact, the metal hook welding area 36 of the metal hook 29 will absorb and consume most of the external impact in the first time, thereby reducing the structural damage that the product may suffer due to external impact.

[0052] In addition, after the product is inserted into the PCB board, to prevent the entire product from floating during soldering, the metal hook 29 is designed with a metal hook plate 37. This metal hook plate 37 will hook onto the back of the PCB board, thereby ensuring that the product and the PCB board are pre-positioned and there will be no jumping phenomenon. At the same time, to prevent the solder from floating during soldering, the metal hook 29 is also designed with a metal hook solder blocker 35. This metal hook solder blocker 35 can block the floating solder, thereby preventing solder rushing.

[0053] In summary, by utilizing the above-mentioned technical solution of this utility model, the anti-vibration connection strength is significantly improved through the coordinated reinforcement design of the metal hook and the PCB board pre-positioning and welding area. The contact stability is significantly enhanced by the six-sided contact wrapping structure of the terminal and the multi-dimensional limiting mechanism. Precise assembly is achieved with the anti-fooling groove and the heat-melting fixing structure. At the same time, the solder baffle plate is used to suppress solder floating and the deformation of the core is reduced by the reinforcing arm. Finally, the dual constraints of the interference fit and the limiting plane ensure the long-term reliable operation of the overall structure under complex working conditions.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
