Description

Technical Field

[0001] This invention relates to the field of connector technology, specifically to a guided positioning connector. Background Technology

[0002] Connectors are key components in electronic, electrical, or mechanical systems used to enable detachable connections between two or more parts, ensuring the stability, reliability, and security of the connection. They transmit data, audio, video, and other signals in electronic devices, and power or charge the devices.

[0003] To overcome the aforementioned defects, prior art (Chinese Patent No. CN217387645U, published on 2022-09-06) discloses a connector, including a connector insulating shell and terminals disposed within the connector insulating shell. A plastic pressure plate is provided on the connector insulating shell near the soldering ends of the terminals. This plastic pressure plate presses the soldering ends of multiple terminals firmly onto the connector insulating shell, preventing inconsistent heights of the soldering ends and thus avoiding impacts on terminal spring-off and soldering. By pressing the soldering ends of multiple terminals firmly onto the connector shell using the plastic pressure plate, inconsistent spring-off and soldering problems caused by different heights of the soldering ends of different terminals are avoided. The pressure plate is placed near the solder feet, and then heat-melted to press the terminals into the shell, improving the flatness of the solder feet to meet reflow soldering requirements and providing a certain holding force.

[0004] Furthermore, prior art 2 (Chinese Patent No. CN116154514A, published on May 23, 2023) discloses a connector and a connector assembly. The connector includes: a housing; a plurality of terminals disposed within the housing; and an insulating member mounted to the housing. The insulating member has raised partitions that are inserted between adjacent terminals to separate them. The separation of adjacent terminals by the partitions of the insulating member increases the creepage distance and clearance between adjacent terminals without increasing the connector's size.

[0005] While existing technologies can provide a certain holding force for connectors, they cannot guide and position them during assembly. This makes connector assembly prone to errors, and inaccurate positioning during male-female connector mating can cause plastic damage, thus presenting certain limitations.

[0006] Therefore, this invention proposes a guided positioning connector to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a guided positioning connector to solve the problems mentioned in the background art, such as the inability to guide and position connectors during assembly, the ease with which assembly errors occur, and the plastic damage caused by inaccurate positioning during male and female connector mating.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a guided positioning connector, comprising a female connector end, a male connector end nested inside the female connector end, and a male connector end boss provided on the side of the male connector end; a female connector end groove opened inside the female connector end; a terminal nested inside the female connector end; a guiding mechanism provided between the male connector end and the female connector end; the guiding mechanism guides the male connector end to docking through a mating plate included therein; and a reminder mechanism provided between the inside of the male connector end and the side of the female connector end; the reminder mechanism provides a reminder of incorrect docking of the male connector end by moving the pressure plate included therein.

[0009] Preferably, the female end groove and the male end boss are in one-to-one correspondence, and when the female end of the connector and the male end of the connector are correctly connected, the male end boss is slidably disposed inside the female end groove.

[0010] Preferably, the guiding mechanism includes a mating plate, which is fixedly connected inside the connector female end, and two sets of mating plates are symmetrically distributed about the center point of the connector female end, and the mating plates are located on the side closer to the front of the connector female end.

[0011] Preferably, the male end of the connector has a mating groove on one side of its front, and the mating groove and the mating plate are positioned in a one-to-one correspondence. When the female end of the connector and the male end of the connector are correctly mated, the mating plate is nested into the mating groove.

[0012] Preferably, the reminder mechanism includes a limiting groove, which is opened on the left and right sides of the female end of the connector, and the limiting groove is at the same horizontal position as the mating plate, and the limiting groove is opened on the side away from the terminal.

[0013] Preferably, the limiting groove is slidably connected to an abutment rod, the pressure plate is fixedly connected to the outer end of the abutment rod, and a second spring is fixedly connected between the inner side of the pressure plate and the female end of the connector, and the pressure plate and the female end of the connector form an elastic structure through the second spring.

[0014] Preferably, the male end of the connector has an internal movable groove, and an auxiliary groove is provided through the movable groove on the side near the outside of the male end of the connector. When the female end of the connector and the male end of the connector are incorrectly connected, the auxiliary groove and the limiting groove are positioned accordingly, and the mating plate is nested and connected to the inside of the movable groove.

[0015] Preferably, a linkage rod is slidably connected inside the movable groove, and a sliding plate is fixedly connected to the outer end of the linkage rod. A rotating rod is hinged to the inner end of the linkage rod. At the same time, the length of the movable groove is less than the maximum length of the docking groove, and the linkage rod slides along the inside of the movable groove through the abutment action of the docking plate.

[0016] Preferably, a limiting rod is slidably connected inside the auxiliary groove, and the inner end of the limiting rod is hinged to the other end of the rotating rod. A first spring is fixedly connected between the end of the limiting rod and the male end of the connector. When the female end of the connector and the male end of the connector are misaligned and connected, the outer end of the limiting rod is nested and connected to the inside of the limiting groove. The abutting rod forms a sliding structure with the limiting rod and the limiting groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the female and male connectors are correctly mated, the male protrusion on the side of the male connector aligns with the female groove inside the female connector. At the same time, the mating plate is nested into the mating groove. Through the cooperation of the female groove, the male protrusion, the mating plate, and the mating groove, the stability of the mating between the female and male connectors can be further ensured, thereby preventing the phenomenon of shaking after the female and male connectors are mated.

[0019] When the female and male terminals of the connector are misaligned, the male protrusion extending outward on the male terminal will immediately come into contact with the corresponding structural part of the female terminal. This contact creates an effective mechanical limit, which can quickly generate significant resistance feedback, directly hindering further mating of the male terminal and preventing the female and male terminals from being inserted backwards or the plastic from being damaged.

[0020] When the female and male terminals of the connector are in a misaligned mating state, the mating plate mates into the interior of the movable slot. Since the length of the movable slot is less than the length of the mating slot, the movable slot can hinder the mating operation of the mating plate, thereby further restricting the mating of the male terminals of the connector. After the user feels the resistance, he / she can know that the mating state is incorrect and thus change the mating direction.

[0021] After the mating plate is inserted into the movable groove, it can abut against the sliding plate. At this time, the rotating rod rotates, causing the abutting rod to slide outward steadily along the limiting groove. At this time, the pressure plate set at the outer end of the abutting rod extends out of the side of the connector female end. The user can observe the position of the pressure plate, thereby further knowing that the connector female end and the connector male end are in a misaligned mating state. Through the double cooperation of the abutting block and the pressure plate, the user is further reminded of the error in the mating state.

[0022] When a user removes the incorrectly mated male connector end, they can manually press the pressure plate, causing it to move the abutment rod inward and abut against the limit rod, thus resetting the limit rod. At this point, the limit rod disengages from the limit groove, allowing the user to remove the male connector end and complete the subsequent correct mating operation. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: As Figure 1 - Figure 5 The present invention provides the following technical solution: a guided positioning connector, wherein: a male connector 2 is nested inside the female connector 1, and a male connector boss 4 is provided on the side of the male connector 2; a female connector groove 3 is provided inside the female connector 1; a terminal 11 is nested inside the female connector 1; the positions of the female connector groove 3 and the male connector boss 4 correspond one-to-one; and when the female connector 1 and the male connector 2 are correctly mated, the male connector boss 4 is slidably disposed inside the female connector groove 3.

[0036] When the female connector 1 and male connector 2 are precisely aligned, the male protrusion 4 on the side of the male connector 2 can align with the corresponding female groove 3 inside the female connector 1. Simultaneously, at another key structural part of the connector, the mating plate 9 is nested and mated into the mating groove 10. The mechanical interlocking structure formed between the female groove 3 and the male protrusion 4 effectively prevents relative displacement between the female connector 1 and the male connector 2 in the horizontal direction. The cooperation between the mating plate 9 and the mating groove 10 further enhances the stability of the connector in the vertical direction, ensuring that the stability of the mating between the female connector 1 and the male connector 2 reaches an extremely high level. This effectively avoids the phenomenon of shaking after the female connector 1 and the male connector 2 are mated, providing a solid and reliable connection foundation for the stable operation of the entire electrical system.

[0037] Example 2: Figure 1 - Figure 5 The present invention provides the following technical solution: a guided positioning connector, wherein a guiding mechanism is provided between the male end 2 and the female end 1 of the connector, and the guiding mechanism guides the male end 2 of the connector to dock through the mating plate 9 included therein. The guiding mechanism includes the mating plate 9, which is fixedly connected inside the female end 1 of the connector. Two sets of mating plates 9 are symmetrically distributed about the center point of the female end 1 of the connector. The mating plates 9 are located on the side closer to the front of the female end 1 of the connector. A mating groove 10 is opened inside the front side of the male end 2 of the connector. The mating groove 10 and the mating plate 9 are positioned in a one-to-one correspondence. When the female end 1 and the male end 2 of the connector are correctly docked, the mating plate 9 is nested and docked into the mating groove 10.

[0038] When the female connector 1 and male connector 2 are misaligned, the male protrusion 4 extending outward from the male connector 2 abuts against the female connector 1, thus hindering the mating of the male connector 2. This eliminates the need for the female connector 1 and male connector 2 to be fully mated before the error is detected; the operator accurately indicates the error through abnormal changes in resistance, effectively preventing forced insertion of the female connector 1 and male connector 2 in the wrong direction. This fundamentally eliminates the possibility of reverse insertion. Furthermore, by promptly interrupting the incorrect mating process, it also prevents stress concentration and mechanical damage to plastic components caused by misalignment, excessive insertion, and removal, significantly improving the connector's performance. For reliability and durability, when the female connector 1 and male connector 2 are in a misaligned docking state, the docking plate 9 will attempt to dock into the movable groove 13. Since the movable groove 13 is shorter than the docking groove 10, the limited length of the movable groove 13 will hinder the deeper docking of the docking plate 9 during the docking process, limiting its continued forward displacement, and thus effectively constraining the docking action of the male connector 2. When the user feels obvious docking resistance during the docking operation, he can quickly judge that there is an error in the current docking state based on this abnormal situation, so as to change the docking direction in time and avoid connector damage or other adverse consequences caused by incorrect docking.

[0039] Example 3: Figure 6 - Figure 10The present invention provides the following technical solution: a guided positioning connector, comprising: a reminder mechanism provided between the inside of the male connector 2 and the side of the female connector 1; the reminder mechanism provides a reminder of incorrect mating of the male connector 2 by moving the pressure plate 5 contained therein; the reminder mechanism includes a limiting groove 8, which is opened on the left and right sides of the female connector 1, and the limiting groove 8 is at the same horizontal position as the mating plate 9, and the limiting groove 8 is opened on the side away from the terminal 11; a contact rod 6 is slidably connected inside the limiting groove 8; the pressure plate 5 is fixedly connected to the outer end of the contact rod 6; a second spring 17 is fixedly connected between the inner side of the pressure plate 5 and the female connector 1; and the pressure plate 5 and the female connector 1 form an elastic structure through the second spring 17; a movable groove 13 is opened inside the male connector 2, and an auxiliary groove 14 is opened through the movable groove 13 near the outer side of the male connector 2. When the female connector 1 and the male connector 2 are misaligned, the length of the movable groove 13 is less than the maximum length of the mating groove 10. The auxiliary groove 14 and the limiting groove 8 are positioned correspondingly. At the same time, the mating plate 9 is nested and mated inside the movable groove 13. The movable groove 13 is slidably connected to a linkage rod 18, and the outer end of the linkage rod 18 is fixedly connected to a slide plate 12. The inner end of the linkage rod 18 is hinged to a rotating rod 15. The linkage rod 18 slides along the inside of the movable groove 13 through the abutment of the mating plate 9. The auxiliary groove 14 is slidably connected to a limiting rod 7, and the inner end of the limiting rod 7 is hinged to the other end of the rotating rod 15. The end of the limiting rod 7 is fixedly connected to the male connector 2 with a first spring 16. When the female connector 1 and the male connector 2 are misaligned, the outer end of the limiting rod 7 is nested and mated inside the limiting groove 8. The abutment rod 6 forms a sliding structure with the limiting rod 7 and the limiting groove 8.

[0040] When the mating plate 9 is successfully mated into the movable groove 13, it will come into contact with the sliding plate 12. Under the force transmitted by the mating plate 9, the sliding plate 12 can synchronously drive the connected linkage rod 18 to slide precisely within the movable groove 13. During the sliding of the linkage rod 18 into the movable groove 13, it will simultaneously trigger the rotating rod 15 hinged at its end to rotate. The rotating rod 15 rotates around the hinge point, and its other end will simultaneously push the limiting rod 7 outward along the auxiliary groove 14 according to a predetermined trajectory. The outwardly moving limiting rod 7 will precisely mate with the limiting groove 8 and come into contact with the abutting rod 6. Under this pressure, the abutting rod 6 will slide stably outward along the limiting groove 8. At this time, the pressure plate 5 installed at the outer end of the abutting rod 6 will extend beyond the side of the connector female end 1. By observing the position of the pressure plate 5, the user can further understand that the connector female end 1 and the connector male end 2 are in a misaligned mating state. This mechanical action generated by the abutting block... The combination of feedback and visual cues from the exposed pressure plate 5 provides users with clear and reliable reminders of incorrect mating status, effectively avoiding a series of problems that may be caused by misaligned mating. When the user needs to remove the male connector 2 that is in an incorrect mating state, they can manually apply pressure to the pressure plate 5. After being pressed by external force, the pressure plate 5 accurately and stably drives the contact rod 6 to move inward along the preset axial direction. During the inward movement of the contact rod 6, it will make effective contact with the limiting rod 7 and transfer the force to the limiting rod 7. After receiving this contact force, the limiting rod 7 can smoothly reset along the guide of the auxiliary groove 14. As the limiting rod 7 resets, it will gradually disengage from the engagement state with the limiting groove 8, thereby releasing the mechanical constraint on the male connector 2. At this time, the user can easily remove the male connector 2, thus creating conditions for subsequent correct mating operations and ensuring that the entire connector system mating process is accurate and reliable.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
