Description

Technical Field

[0001] The utility model relates to the technical field of MINIFAKRA board-end connectors, in particular to an outer conductor of a MINIFAKRA board-end connector. Background Art

[0002] With the development of automobile intelligence, the signals that need to be transmitted by systems such as vehicle-mounted intelligent driving systems and vehicle-mounted human-computer interaction systems have become more complex. In this context, the MINI FAKRA connector is designed for communication inside and outside the car and between cars. It has now become a universal standard RF connector in the automotive industry. The MINIFAKRA board-end connector is provided with an outer conductor for connecting the main housing and the PCB board. The main housing is provided with a center conductor that passes through the outer conductor, and the center conductor is electrically connected to the PCB board.

[0003] The side wall on one side of the outer conductor is connected to the main shell, and the bottom of the outer conductor needs to be connected to the PCB board, which is usually connected by welding. In the actual assembly process, mechanical manipulation is mostly used because the side wall on one side of the outer conductor is connected to the main shell, and the overall center of gravity is unbalanced. Under the influence of gravity, the mechanically lifted outer conductor and the components of the main shell may be skewed to a certain extent. When the outer conductor is connected to the PCB board in a skewed state, a gap will be caused between the surface of the PCB board and the bottom wall of the outer conductor, which may cause problems in the electrical connection between the center conductor and the PCB board, affecting product performance. Therefore, improvements are needed. Utility Model Content

[0004] In order to reduce the possibility of the outer conductor being skewed and improve product quality, the present application provides a MINIFAKRA board-end connector outer conductor.

[0005] The outer conductor of a MINIFAKRA board-end connector provided in this application adopts the following technical solution:

[0006] A MINIFAKRA board-end connector outer conductor comprises a base and a guide column, wherein the guide column is arranged at the bottom of the base, a boss is arranged on a side wall of the base, the guide column is provided with a clamping block, and the clamping block is provided with a guiding surface.

[0007] By adopting the above technical solution, the bosses are arranged on both sides of the base body to increase the weight of the outer conductor, so as to adjust the center of gravity position of the outer conductor after being connected to the main shell body, so as to balance the overall connection between the outer conductor and the main shell body, and reduce the possibility of rotation and skewing of the outer conductor due to the center of gravity offset after being connected to the main shell body during assembly, so that the outer conductor is connected to the PCB board in a horizontal state, thereby reducing the possibility of problems with the PCB electrical connection and improving product quality. At the same time, the PCB board is provided with a guide hole for the guide column to pass through, and the PCB board is also provided with a guide groove communicating with the guide hole, and the guide surface facilitates the insertion of the card block into the guide groove. When the PCB board is installed, the guide column is passed through the guide hole and the card block is inserted into the guide groove at the same time. The card block on the guide column further increases the weight of the outer conductor itself for balance. At the same time, if the outer conductor is in a skewed state, the card block will be against the surface of the PCB board when the PCB board is connected, so that the PCB board cannot be assembled, thereby reducing the material waste caused by incorrect assembly of the PCB board.

[0008] Preferably, the base is provided with a connecting column, and the connecting column is provided with a connecting groove.

[0009] By adopting the above technical solution, the connecting column increases the weight of the outer conductor, further balances the center of gravity and reduces the possibility of the outer conductor being skewed. At the same time, the connecting column is also used to be inserted into a groove adapted on the main shell. At the same time, the main shell is provided with a corresponding plug-in inserted into the connecting groove. The outer conductor and the main shell are connected to each other through the connecting column and the connecting groove, thereby improving the convenience of connecting the outer conductor and the main shell.

[0010] Preferably, the base is provided with a positioning column, and the positioning column is provided with an inclined surface on a side away from the base.

[0011] By adopting the above technical solution, the positioning column can further increase the weight of the outer conductor, further balance the center of gravity and reduce the possibility of the outer conductor being skewed, and is also used to be inserted into the corresponding slot on the main shell. The positioning column is abutted against the inner wall of the slot of the outer shell to improve the stability of the connection between the outer conductor and the main shell, and the inclined surface improves the convenience of inserting the positioning column into the slot of the main shell.

[0012] Preferably, the side wall of the positioning column is provided with an abutment block, and the abutment block is provided with a guide surface.

[0013] By adopting the above technical solution, the abutment block further increases the weight of the outer conductor, further balances the center of gravity and reduces the possibility of the outer conductor being skewed. At the same time, the abutment block can be smoothly inserted into the corresponding groove on the main shell through the guide surface. The abutment block is provided to increase the tensile strength between the outer conductor and the main shell, thereby improving the stability of the connection between the outer conductor and the main shell.

[0014] Preferably, a counterweight block is provided on the side wall of the base body away from the positioning column, and the bottom wall of the counterweight block is flush with the bottom wall of the base body.

[0015] By adopting the above technical solution, the counterweight block is arranged on the side of the base away from the positioning column, which is also the side away from the main shell after the base is connected to the main shell, so as to increase the weight of the outer conductor and better balance the overall center of gravity, thereby reducing the possibility of the outer conductor being skewed. At the same time, the bottom wall of the counterweight block is flush with the bottom wall of the base, so that when the outer conductor is connected to the PCB board, the bottom wall of the base is against the surface of the PCB board, and the counterweight block also is against the surface of the PCB board. By increasing the area against the surface of the PCB board, the possibility of the PCB board and the outer conductor being skewed and leaving a gap is further reduced, the unstable electrical connection of the PCB board is reduced, and the product quality is improved.

[0016] Preferably, the boss is provided with an auxiliary block, and the bottom wall of the auxiliary block is flush with the bottom wall of the counterweight block.

[0017] By adopting the above technical solution, the auxiliary block on the boss increases the weight of the outer conductor and reduces the possibility of the outer conductor being skewed. At the same time, the bottom wall of the auxiliary block is flush with the bottom wall of the counterweight block, so that the auxiliary block can also abut against the surface of the PCB board, further increasing the area abutting against the surface of the PCB board, improving the stability of the connection between the outer conductor and the PCB board, and reducing the possibility of a skew and gap between the PCB board and the outer conductor, thereby reducing the unstable electrical connection of the PCB board and improving product quality.

[0018] Preferably, the auxiliary block is provided with a connecting block, the connecting block is connected to the counterweight block, and the bottom wall of the connecting block is flush with the bottom wall of the auxiliary block.

[0019] By adopting the above technical solution, the connecting block connects the counterweight block and the auxiliary block, which increases the weight of the outer conductor and reduces the possibility of the outer conductor being skewed. At the same time, the area against the surface of the PCB board is further increased, thereby improving the stability of the connection between the outer conductor and the PCB board, thereby improving the product assembly quality.

[0020] Preferably, the side wall of the boss is provided with an auxiliary groove.

[0021] By adopting the above technical solution, relevant column blocks inserted into the auxiliary grooves can be provided on the main shell, and the stability of the connection between the main shell and the outer conductor can be further improved by inserting the relevant column blocks on the main shell into the auxiliary grooves on the bosses.

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

[0023] 1. By providing a base, a guide column, a boss, a block and a guide surface, the guide column, the boss and the block increase the overall gravity of the outer conductor, especially the bosses provided on both sides of the outer conductor, so as to balance the outer conductor and the main housing as a whole, and reduce the possibility of the outer conductor being skewed relative to the vertical plane due to the excessive weight of the main housing after the outer conductor and the main housing are connected, thereby increasing the possibility of normal assembly of the outer conductor and the PCB board, improving the overall assembly quality, and at the same time increasing the probability of the block being smoothly inserted into the slot on the PCB board through the guide surface, further facilitating the overall assembly;

[0024] 2. By providing auxiliary grooves, connecting columns, connecting grooves, positioning columns, inclined surfaces, abutment blocks and guide surfaces, when connecting the outer conductor and the main shell, the corresponding plug-in blocks on the main shell are inserted into the auxiliary grooves on the outer conductor bosses, and the connecting columns and positioning columns are inserted into the corresponding slots on the main shell, and the corresponding plug-in blocks on the main shell are inserted into the connecting grooves on the connecting columns. At the same time, the inclined surfaces facilitate the positioning columns to be inserted into the corresponding slots and the guide surfaces facilitate the abutment blocks to be inserted into the corresponding slots, thereby improving the tensile strength between the main shell and the outer conductor and improving the stability of the connection between the outer conductor and the main shell;

[0025] 3. By arranging a counterweight block, an auxiliary block and a connecting block, the overall center of gravity can be further adjusted by arranging a counterweight block on the side of the base away from the main shell. At the same time, auxiliary blocks and connecting blocks are also arranged. While further balancing the center of gravity, the contact area with the surface of the PCB board is increased, the possibility of skewness and gaps between the PCB board and the outer conductor is reduced, the unstable electrical connection of the PCB board is reduced, and the product quality is improved.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application embodiment discloses a MINIFAKRA board-end connector outer conductor. Figure 1 and Figure 2 , which includes a base 1 and a plurality of guide pillars 3 fixedly arranged on the bottom wall of the base 1, a ring-shaped block 31 fixedly arranged on the side wall of the guide pillar 3, the top wall of the block 31 is fixedly connected to the bottom wall of the base 1, and a guide surface 311 is arranged on the bottom wall of the block 31. A guide hole is arranged through the side wall of the base 1. According to different specifications, one or more guide holes can be arranged. In this embodiment, one guide hole is arranged. Bosses 2 are integrally arranged on the side walls on both sides of the base 1. By arranging the bosses 2 and the blocks 31, the weight of the outer conductor is increased, thereby balancing the center of gravity of the overall component after the outer conductor is connected to the main shell, reducing the possibility of the outer conductor being skewed relative to the vertical plane after the components assembled with the outer conductor and the main shell are lifted, thereby reducing the possibility of problems occurring during the assembly process and improving the assembly quality.

[0031] In order to improve the stability of the connection between the outer conductor and the main shell, refer to Figure 1 and Figure 2 , a connecting column 11 is fixedly provided on the side wall of the base 1, and the connecting column 11 is arranged on both sides of the guide hole. The connecting column 11 is provided with a connecting groove 111, and the connecting groove 111 is communicated with the side wall of the connecting column 11 away from the guide hole. A positioning column 4 is also fixedly provided on the side wall of the base 1 on the side where the connecting column 11 is provided, and the positioning column 4 is arranged on both sides of the guide hole, and the side wall of the positioning column 4 away from the base 1 is provided with an inclined surface 41. An abutment block 42 is provided on the side wall of the positioning column 4, and a pair of guide surfaces 421 are provided on the side wall of the abutment block 42 away from the base 1. An auxiliary groove 22 is provided on the side wall of the boss 2. When assembling the outer conductor and the main shell, the positioning column 4, the abutment block 42 and the connecting column 11 on the outer conductor are inserted into the corresponding slots of the main shell, and at the same time, the corresponding plug-in block on the main shell is inserted into the connecting groove 111 or the auxiliary groove 22, thereby improving the stability of the connection between the main shell and the outer conductor.

[0032] To further balance the center of gravity, refer to Figure 1 and Figure 2A counterweight 5 is fixedly provided on the side wall of the base 1 away from the positioning column 4, and the bottom wall of the counterweight 5 is flush with the bottom wall of the base 1. An auxiliary block 21 is fixedly provided on the surface of the boss 2 away from the base 1, and the bottom wall of the auxiliary block 21 is flush with the bottom wall of the counterweight 5. The auxiliary block 21 is integrally provided with a connecting block 211, and the connecting block 211 is integrally connected to the side wall of the counterweight 5, and the bottom wall of the connecting block 211 is flush with the bottom walls of the auxiliary block 21 and the counterweight 5. The edges and corners of the base 1, the auxiliary block 21, the connecting block 211 and the counterweight 5 are all rounded. The center of gravity is further balanced by arranging the auxiliary block 21, the connecting block 211 and the counterweight 5, especially the counterweight 5 is arranged on the side of the base 1 away from the main shell, which effectively reduces the probability of the outer conductor tilting in the vertical direction when it is lifted and assembled after connecting to the main shell. At the same time, by providing the auxiliary block 21, the connecting block 211 and the counterweight block 5, the contact area with the surface of the PCB board is enlarged, and the connection stability is increased. When the outer conductor is skewed, the PCB board will interfere with the bottom wall of the auxiliary block 21, the connecting block 211 or the counterweight block 5, so that the guide column 3 cannot be fully inserted into the PCB board, thereby stopping the assembly, reducing the cost loss caused by incorrect assembly.

[0033] The implementation principle of the outer conductor of a MINIFAKRA board-end connector in an embodiment of the present application is: the weight of the outer conductor is increased by setting components such as a boss 2, an auxiliary block 21 and a counterweight block 5. The specific sizes and masses of the boss 2, the auxiliary block 21 and the counterweight block 5 can be adjusted accordingly according to the specifications and masses of the outer conductor and the main shell, so that the overall center of gravity of the outer conductor and the main shell is relatively balanced after assembly, and the possibility of the assembly center of gravity being unstable and skewed when the assembly of the outer conductor and the main shell is lifted during assembly is reduced, so that the outer conductor and the PCB board are assembled correctly, thereby ensuring the assembly quality and the quality of the product after assembly.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
