Abstract
Description
Technical Field
[0001] This utility model relates to the field of female connector technology, and specifically to a reverse-insertion female connector. Background Technology
[0002] Female header connectors are a type of universal connection device widely used in electronics, electrical appliances and instruments. They are mainly used for current or signal transmission and are usually used with pin header connectors to form board-to-board connections. Their function is to act as a bridge between blocked or isolated circuits, and to undertake the task of current or signal transmission. They are usually used with pin headers or electronic wire harness terminals.
[0003] Existing female connectors require pins to be inserted into corresponding sockets during use to achieve connection. However, since the sockets and pins are arranged in an array and have the same specifications, it is very easy for operators to insert them in reverse, which not only causes inconvenience to operators but also results in low insertion performance. Therefore, there is an urgent need for a reverse-insertion female connector to solve the above problems. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The technical problem to be solved by this utility model is to provide a reverse-insertion female connector that can remind workers to avoid reverse insertion, has high insertion performance and good use effect, in light of the current situation of the prior art.
[0006] (II) Technical Solution
[0007] This utility model is achieved through the following technical solution: This utility model proposes an anti-reverse plug female connector, including a female connector body. Lifting cavities are provided on both sides of the upper end of the female connector body. Two sets of telescopic columns are symmetrically installed in the lifting cavities. Springs are sleeved on the outer sides of the telescopic columns. A lifting plate is fixed on the movable part of the telescopic columns. A first magnetic plate is provided inside the upper end of the lifting plate. Two sets of second magnetic plates are symmetrically installed on both sides of the bottom end of the female connector body at positions corresponding to the lifting plates. Multiple sets of sockets are arrayed on the upper end of the female connector body, and multiple sets of pins are arrayed on the bottom end of the female connector body.
[0008] Furthermore, the fixing part of the telescopic column is connected to the lifting cavity by screws, and the spring is welded to the outer wall of the telescopic column.
[0009] By adopting the above technical solution, the combination of the telescopic column and the spring enables the lifting plate to have a certain lifting performance.
[0010] Furthermore, the lifting plate is fixed to the movable part of the telescopic column by screws, and the lifting plate is slidably connected to the lifting cavity.
[0011] By adopting the above technical solution, after the female connector is plugged in, the lifting plate can be placed in the lifting cavity, thereby storing the lifting plate.
[0012] Furthermore, the first magnetic plate is embedded inside the top of the lifting plate, and the two sets of the first magnetic plates have opposite magnetic properties.
[0013] By adopting the above technical solution, the lifting plate provides an installation position for the first magnetic plate.
[0014] Furthermore, the second magnetic plate is embedded inside the bottom end of the main body of the female connector, and the two sets of second magnetic plates have opposite magnetism.
[0015] By adopting the above technical solution, during the insertion process of the female connector body, when the insertion position is accurate, the first magnetic plate and the second magnetic plate can automatically attract each other, thereby pre-connecting the female connector body.
[0016] Furthermore, the first magnetic plate and the second magnetic plate, which are located in the same vertical plane, have opposite magnetic properties.
[0017] By adopting the above technical solution, when the insertion positions are reversed, the first magnetic plate can generate a repulsive force on the second magnetic plate due to the repulsion of like magnetic poles. This repulsive force can be perceived by the staff, thus reminding them to reverse the insertion position, which can effectively avoid reverse insertion and has a good effect.
[0018] Furthermore, a locking hole is provided on one side wall of the lifting plate, and a locking bolt is installed on one side wall of the main body of the female connector at a position corresponding to the locking hole.
[0019] By adopting the above technical solution, when the lifting plate is in the lifting cavity, the locking bolt is rotated to connect it to the locking hole, thereby fixing the lifting plate.
[0020] Furthermore, both the pins and the sockets are formed on the body of the female connector, and the pins are inserted into the sockets.
[0021] By adopting the above technical solution, the pins and the sockets can be combined to realize the connection of the main body of the female connector.
[0022] (III) Beneficial Effects
[0023] Compared with the prior art, this utility model has the following advantages:
[0024] To address the problem that existing female connectors require pins to be inserted into corresponding sockets for connection, and that the arrayed and uniform pin configuration makes reverse insertion easy, causing inconvenience and poor connection performance, this invention addresses this issue by incorporating a lifting plate, telescopic column, spring, first magnetic plate, and second magnetic plate. During insertion, when the orientation is reversed, the repulsive force between the first and second magnetic plates creates a repulsive force that the operator can perceive, prompting them to reverse the insertion position. Simultaneously, the attraction between the first and second magnetic plates allows for pre-connection. Finally, the telescopic column and spring position the lifting plate within its lifting chamber, enabling a one-step, fully connected connection with superior performance. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] like Figures 1-3As shown, an anti-reverse socket female connector in this embodiment includes a female connector body 1. Lifting cavities 4 are provided on both sides of the upper end of the female connector body 1. Two sets of telescopic columns 10 are symmetrically installed inside the lifting cavities 4. Springs 11 are sleeved on the outside of the telescopic columns 10. The combination of the telescopic columns 10 and the springs 11 allows the lifting plate 5 to have a certain lifting performance. The lifting plate 5 is fixed on the movable part of the telescopic columns 10. A first magnetic plate 6 is provided inside the upper end of the lifting plate 5. Two sets of second magnetic plates 9 are symmetrically installed on both sides of the bottom end of the female connector body 1 at positions corresponding to the lifting plate 5. During the insertion process of the female connector body 1, when the insertion position is accurate, the first magnetic plate 6 and the second magnetic plate 9 can automatically attract each other, thereby pre-connecting the female connector body 1. When the insertion position is reversed, the first magnetic plate 6 can generate a repulsive force on the second magnetic plate 9 under the effect of magnetic repulsion. This repulsive force can be perceived by the staff, thus reminding the staff to turn the insertion position, which can effectively avoid reverse insertion and has a good effect. The upper end of the female connector body 1 is arrayed with multiple sets of sockets 2, and the bottom end of the female connector body 1 is arrayed with multiple sets of pins 3.
[0032] like Figures 1-3 As shown, in this embodiment, the fixed part of the telescopic column 10 is connected to the lifting cavity 4 by screws, the spring 11 is welded to the outer wall of the telescopic column 10, the lifting plate 5 is fixed to the movable part of the telescopic column 10 by screws, the lifting plate 5 is slidably connected to the lifting cavity 4, the first magnetic plate 6 is embedded inside the top of the lifting plate 5, the two sets of first magnetic plates 6 have opposite magnetism, the second magnetic plate 9 is embedded inside the bottom of the main body 1 of the female connector, the two sets of second magnetic plates 9 have opposite magnetism, and the first magnetic plate 6 and the second magnetic plate 9 located in the same vertical plane have opposite magnetism.
[0033] like Figures 1-3 As shown, in this embodiment, a locking hole 7 is provided on one side wall of the lifting plate 5, and a locking bolt 8 is installed on one side wall of the female connector body 1 at a position corresponding to the locking hole 7. When the lifting plate 5 is in the lifting cavity 4, the locking bolt 8 is rotated to connect it with the locking hole 7, thereby fixing the lifting plate 5. The pin 3 and the socket 2 are both formed on the female connector body 1. The pin 3 is inserted into the socket 2. The combination of the pin 3 and the socket 2 can realize the connection of the female connector body 1.
[0034] The specific implementation process of this embodiment is as follows: During use, when the pin 3 is inserted into the socket 2, if the insertion position is accurate, the first magnetic plate 6 and the second magnetic plate 9 can automatically attract each other, thereby pre-connecting the main body 1 of the female connector. Then, pressure is applied to make the pin 3 be in the socket 2. At this time, under the action of the telescopic column 10 and the spring 11, the lifting plate 5 is placed in the lifting cavity 4. Then, the locking bolt 8 is rotated to connect it with the locking hole 7, thereby fixing the lifting plate 5. When the insertion position is reversed, the first magnetic plate 6 can generate a repulsive force on the second magnetic plate 9 under the action of magnetic repulsion. This repulsive force can be perceived by the staff, thereby reminding the staff to turn the insertion position, which can effectively avoid reverse insertion and achieve one-step insertion. It has good applicability.
