Description

Technical Field

[0001] The utility model relates to the technical field of MINIFAKRA line end connectors, in particular to a MINIFAKRA line end connector shielding shell. 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, and has now become a universal standard RF connector in the automotive industry.

[0003] The MINIFAKRA line end connectors in the prior art are mostly provided with a shielding shell, which mostly includes a front end and a rear end. During assembly, the front end shell and the rear end shell are combined together, and then connected by laser welding or other welding methods. The overall manufacturing process is relatively inconvenient. Utility Model Content

[0004] In order to improve the convenience of manufacturing, the present application provides a MINIFAKRA line end connector shielding shell.

[0005] The MINIFAKRA line end connector shielding shell provided in this application adopts the following technical solution:

[0006] A MINIFAKRA line end connector shielding shell comprises a shell and a dovetail block, wherein the shell is provided with a through hole, the shell is provided with an open slot communicating with the through hole, the dovetail block is arranged on the inner wall of the open slot, the inner wall of the open slot is provided with a dovetail slot, and the dovetail block is inserted into the insertion slot.

[0007] By adopting the above technical scheme, the shell is formed in one piece. Therefore, compared with the assembly of the front end shell and the rear end shell in the prior art, there is no need for assembly steps such as welding, which greatly simplifies the production process. At the same time, the shell is provided with an open groove, so that the shell itself has a certain elasticity, which is convenient for subsequent assembly with other components. At the same time, the shell is connected by inserting the dovetail block into the dovetail groove, which improves the overall stability of the shell itself and reduces the possibility of the shell expanding after stamping and rounding during the production process, making the production of the shell itself simpler and more reasonable, and improving the convenience of production by simplifying the assembly and production steps.

[0008] Preferably, the inner wall of the dovetail groove is provided with a limit block which abuts against the dovetail block.

[0009] By adopting the above technical solution, the dovetail block is supported by the limit block, thereby reducing the possibility of the dovetail block moving along its own thickness direction and causing the dovetail block to detach from the dovetail groove, improving the stability of the dovetail block inserted into the dovetail groove, thereby improving the stability of the overall structure of the shell itself, reducing the possibility of the shell expanding along the opening groove after the dovetail block detaches from the dovetail groove, and improving the durability of the shell.

[0010] Preferably, the dovetail block is provided with a limiting groove, the limiting block is inserted into the limiting groove, and the limiting block abuts against the inner wall of the limiting groove.

[0011] By adopting the above technical solution, the limit block is inserted into the limit groove, so as to further improve the stability of the dovetail block inserted into the dovetail groove. The limit block is abutted against the bottom wall and side wall of the limit groove, and the dovetail block is limited from two directions, thereby further reducing the possibility of the dovetail block detaching from the dovetail groove and causing the shell itself to expand.

[0012] Preferably, the limit block is integrally connected to the inner wall of the dovetail groove, and the top wall of the limit block is flush with the surface of the shell.

[0013] By adopting the above technical solution, the limit block is integrally connected to the shell, thereby reducing the possibility of the limit block being separated from the shell after a collision, thereby reducing the possibility of the dovetail block detaching from the dovetail block shell and expanding after the limit block is damaged, thereby further improving the durability of the shell itself. At the same time, by setting the surface of the limit block to be flush with the surface of the shell, the probability of the limit block being hit is reduced, and the possibility of the limit block protruding or protruding from the shell surface to affect subsequent assembly and use is reduced, thereby improving convenience of use.

[0014] Preferably, a plurality of connection blocks are provided at one end of the shell, and connection grooves are formed between adjacent connection blocks.

[0015] By adopting the above technical solution, the shell is connected to other corresponding components, the corresponding component is inserted into the through hole of the shell, the connecting block can be inserted into the corresponding slot on the corresponding component, and at the same time, the insert block on the corresponding component is inserted into the connecting slot to connect with the corresponding component. The corresponding component itself can be inserted into the through hole in the center of the shell. The stability of the shell connection is improved by setting the connecting slot and the connecting block.

[0016] Preferably, the connecting block is provided with an arc-shaped block, and the arc-shaped block is arranged between two adjacent connecting grooves.

[0017] By adopting the above technical solution, the shell is mostly an injection molded part, and the connecting block itself has a certain elasticity, which facilitates the connection with the corresponding components. The strength of the connecting block itself is increased by arranging the arc block, which reduces the possibility of the connecting block being broken due to excessive pressure when plugged into the corresponding component, increases the stability of the connection, and improves the overall durability.

[0018] Preferably, a positioning column is provided on the inner wall of the connecting groove.

[0019] By adopting the above technical solution, the positioning column is used to be inserted into the slot on the corresponding component, and the stability of the connection between the shell and the corresponding component is further improved by providing the positioning column.

[0020] Preferably, one of the connecting grooves is communicated with the opening groove, and a positioning column close to the opening groove is provided with an auxiliary groove communicated with the opening groove.

[0021] By adopting the above technical solution, the auxiliary groove on the positioning column is connected to the opening groove. When the shell is connected to the corresponding component, the positioning column is inserted into the slot on the corresponding component. The inner walls on both sides of the slot are used to support the positioning column so that the positioning column will not expand along the auxiliary groove, thereby reducing the possibility of the shell expanding along the opening groove and improving the stability of the shell itself.

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

[0023] 1. By setting a shell, a dovetail block, a through hole, an open slot and a dovetail slot, the through hole on the shell is used to insert and place corresponding components, the shell itself is integrally formed, and the shell itself has a certain elasticity by setting the open slot, so as to facilitate assembly with corresponding components, and at the same time, a dovetail block is set, and inserting the dovetail block into the dovetail slot can reduce the possibility of the shell expanding along the direction of the open slot, thereby improving the stability of the shell itself in use. Compared with the shielding shell in the prior art, the front end shell and the rear end shell need to be fixedly connected by laser welding. The integrated shell simplifies the assembly steps and improves the convenience of production. At the same time, the shell is made elastic by setting the open slot, which improves the convenience of subsequent assembly compared with other shielding shells without open slots.

[0024] 2. By setting the limit block and the limit groove, the limit block set on the inner wall of the dovetail groove is inserted into the limit groove on the dovetail block, so as to reduce the possibility of the dovetail block moving along its own thickness direction and leaving the dovetail groove. The inner bottom wall and the inner wall of the limit groove are pressed against the limit groove, so as to improve the stability of the dovetail block inserted into the dovetail groove, reduce the possibility of the shell expanding along the opening groove after the dovetail block leaves the dovetail groove, and improve the durability of the shell;

[0025] 3. By setting a connecting block, a connecting groove, an arc block, a positioning column and an auxiliary groove, the connecting block is set at one end of the shell for inserting the slot hole of the corresponding component. The connecting block itself is elastic and the arc block is set to improve its strength, thereby reducing the probability of breakage during use. At the same time, the plug-in block on the corresponding component is inserted into the connecting groove, and the positioning column is inserted into the slot hole on the plug-in block. By setting the connecting block, the connecting groove and the positioning column, the stability of the connection between the shell and the corresponding component is improved. The positioning column on the connecting groove that communicates with the open groove is provided with an auxiliary groove, and the auxiliary groove is communicated with the open groove. The positioning column inserted into the slot hole is counteracted by the inner wall of the slot hole, thereby reducing the possibility of the positioning column expanding along the auxiliary groove, and at the same time reducing the possibility of the shell expanding along the open groove.

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

[0030] The present application embodiment discloses a MINIFAKRA line end connector shielding shell. Figure 1 to Figure 2 , which includes a shell 1 and a plurality of dovetail blocks 2. The shell 1 is provided with a through hole 11 along the length direction. The outer wall of the shell 1 is provided with an open groove 12 connected with the through hole 11 along the length direction. The open groove 12 passes through the side walls of the shell 1 at both ends. The dovetail block 2 is fixedly arranged on the inner wall of the open groove 12. The side wall of the open groove 12 away from the dovetail block 2 is provided with a dovetail groove 21. The dovetail block 2 is adapted to be inserted into the dovetail groove 21. The shell 1 is integrally formed and has a certain elasticity by providing the open groove 12, which facilitates the insertion of the corresponding parts into the through hole 11. At the same time, by providing the dovetail block 2, the dovetail block 2 is adapted to be inserted into the dovetail groove 21, which reduces the possibility of the shell 1 expanding along the open groove 12. Compared with the prior art in which the shells 1 at both ends are assembled by laser welding, the present application simplifies the manufacturing steps and improves the convenience of manufacturing by using the integrally formed shell 1.

[0031] In order to improve the stability of the dovetail block 2 inserted into the dovetail groove 21, refer to Figure 1 and Figure 2The inner wall of the dovetail groove 21 is integrally fixed with a limiting block 211, and the surface of the limiting block 211 is flush with the surface of the housing 1. The surface of the dovetail block 2 is provided with a limiting groove 22 that communicates with the side wall, and the limiting block 211 is adapted to be inserted into the limiting groove 22 and abuts against the inner wall of the limiting groove 22. By inserting the limiting block 211 into the limiting groove 22, the dovetail block 2 is limited in the thickness direction of the dovetail block 2, reducing the possibility of the dovetail block 2 being separated from the dovetail groove 21, and improving the stability of the dovetail block 2 inserted into the dovetail groove 21.

[0032] In order to improve the stability of the connection between the housing 1 and the corresponding components, refer to Figure 1 and Figure 2 Four connecting blocks 3 are provided at one end of the housing 1, connecting grooves 32 are formed between adjacent connecting blocks 3, and the side walls of the connecting blocks 3 are inclined so that the width of the connecting block 3 away from the housing 1 is greater than the width of the connecting block 3 near the housing 1. The connecting block 3 is integrally provided with an arc block 31, which is arranged between two adjacent connecting grooves 32, and the surface of the arc block 31 is higher than the surface of the connecting block 3. The stability of the connection between the housing 1 and the corresponding component is improved by inserting the connecting block 3 into the slot on the corresponding component and inserting the plug on the corresponding component into the connecting groove 32.

[0033] In order to further improve the stability of the housing 1 itself, refer to Figure 2 The bottom wall of the connection groove 32 is integrally provided with a positioning column 33, and the positioning column 33 is integrally connected with the housing 1. One of the connection grooves 32 is in communication with the opening groove 12, and the positioning column 33 disposed on the inner wall of the connection groove 32 in communication with the opening groove 12 is provided with an auxiliary groove 331, which passes through both ends of the positioning column 33 and is in communication with the opening groove 12. The positioning block is inserted into the slot hole on the corresponding component plug-in block, so as to further improve the stability of the connection between the housing 1 and the corresponding component, and at the same time, the positioning block is supported by the slot hole, so as to reduce the possibility of the positioning column 33 expanding along the auxiliary groove 331, thereby reducing the possibility of the housing 1 expanding along the opening groove 12.

[0034] The implementation principle of a MINIFAKRA line-end connector shielding shell in an embodiment of the present application is as follows: the shell 1 is formed in one piece, and compared with the split shielding shell in the prior art, the one-piece formed shell 1 does not need to be assembled by laser or ultrasonic welding, etc., which simplifies the production steps, thereby improving the convenience of production. At the same time, by setting the opening groove 12, the shell 1 itself has a certain elasticity, while the shell 1 without the opening groove 12 is not elastic enough to install the corresponding parts. After the opening groove 12 is set, the shell 1 may expand along the opening groove 12, so a dovetail block 2 and a dovetail groove 21 are set, and the dovetail block 2 is inserted into the dovetail groove 21, thereby reducing the possibility of the shell 1 expanding along the opening groove 12. The overall production steps of the shielding shell are simplified, which facilitates production and improves the convenience of assembling other parts of the shielding shell.

[0035] 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.
