Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a board-end radio frequency connector and connector assembly. Background Technology

[0002] With the technological advancements in the automotive industry, vehicles are becoming increasingly intelligent and feature-rich, leading to a surge in the number of electronic devices integrated into them. This has resulted in a significant increase in the demand for board-side radio frequency (RF) connectors, and their application scenarios are becoming more complex. Current board-side RF connectors, such as... Figure 1 As shown, its structure mostly consists of an RF transmission component and a plastic housing 20. The RF transmission component includes a shielding shell 10 made of metal and a terminal assembly 30 installed inside the shielding shell 10. The shielding shell 10 and the terminal assembly 30 are soldered to the circuit board 1 inside the device via pins. The plastic housing 20 is generally mechanically integrated with the shielding shell 10, together forming the socket for the board-end connector to mate with the wire harness connector. For board-end RF connectors, in use, the plastic housing 20, in addition to needing to withstand axial tensile force like a wire harness connector, also needs to withstand lateral bias forces from different directions. For details, please refer to [link to relevant documentation]. Figure 2 Currently, most products on the market exhibit high reliability in terms of the holding force of the plastic housing when facing axial tensile forces. However, problems often arise when facing lateral bias forces. The main issue is that the plastic housing deflects under bias forces, affecting the mating process, and in severe cases, the plastic housing may even detach. Therefore, achieving a reliable fit between the plastic housing and the RF transmission components, enabling it to withstand stringent bias force requirements, is a significant challenge in the design of board-side RF connectors. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a board-end radio frequency connector and connector assembly to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a board-end radio frequency connector, soldered to a circuit board and mated with its docking connector, includes a shielding shell made of metal material, a plastic shell sleeved on the outside of part of the shielding shell, and a terminal assembly installed inside the shielding shell. The shielding shell and the terminal assembly are respectively soldered to the circuit board. The shielding shell has vertical ribs symmetrically arranged on two side walls perpendicular to the circuit board for snapping the plastic shell. The extension direction of the vertical ribs is perpendicular to the insertion direction of the board-end radio frequency connector and the docking connector.

[0005] The shielding shell is perpendicular to two side walls of the circuit board, and at least one side wall is provided with a horizontal rib perpendicular to the vertical rib. The plastic shell is provided with a vertical groove for engaging the vertical rib and a horizontal groove for accommodating the horizontal rib.

[0006] In some embodiments, the shielding shell has horizontal ribs perpendicular to the vertical ribs on both side walls perpendicular to the circuit board.

[0007] In some embodiments, the horizontal ribs and the vertical ribs are not continuously arranged.

[0008] In some embodiments, the horizontal rib has a rectangular cross-section.

[0009] In some embodiments, the shielding shell has a top short rib on its side wall parallel to the circuit board, and the plastic shell has a corresponding short groove for engaging the top short rib.

[0010] In some embodiments, the top short rib, horizontal rib, and vertical rib are all inclined surfaces with a guiding function on the side facing the plastic shell, and the side away from the plastic shell is a vertical surface perpendicular to the corresponding side wall of the shielding shell.

[0011] In some embodiments, the shielding shell, top short rib, horizontal rib, and vertical rib are integrally formed.

[0012] In some embodiments, at least one of the inner wall of the plastic shell and the outer wall of the shielding shell is provided with a plurality of protrusions spaced circumferentially along its upper edge.

[0013] In some embodiments, the outer wall of the shielding shell is formed with positioning ribs arranged along the axial direction of the shielding shell, and the end of the plastic shell facing the shielding shell is recessed inward to form a positioning notch that slides with the positioning ribs. During the process of inserting the plastic shell into the shielding shell, the positioning notch and the positioning ribs slide with each other to achieve positioning of the assembly of the two.

[0014] The present invention provides a connector assembly, including a circuit board, a board-end RF connector, and a mating connector that is inserted and mated with the board-end RF connector, wherein the board-end RF connector is soldered to the circuit board.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides mutually perpendicular vertical ribs and horizontal ribs on the side wall of the board-end RF connector perpendicular to the circuit board. The vertical ribs and horizontal ribs respectively cooperate with the vertical grooves and horizontal grooves provided on the plastic shell to prevent the plastic shell from deflecting when subjected to bias forces in the left-right and up-down directions. This ensures that the plastic shell will not deflect under bias forces in different directions, achieving a reliable fit between the plastic shell and the RF transmission component. It can effectively prevent the plastic shell from deflecting or falling off, thus affecting the mating of the connector assembly. Attached Figure Description

[0029] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0032] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0033] A board-side radio frequency connector 2, such as Figures 3-5 As shown, the board-end RF connector 2 is soldered to the circuit board 1 and plugged into its mating connector (not shown in the figure). The board-end RF connector 2 includes a shielding shell 10 made of metal material, a plastic shell 20 sleeved on the outside of part of the shielding shell 10, and a terminal assembly 30 installed inside the shielding shell 10. The shielding shell 10 and the terminal assembly 30 are soldered to the circuit board 1 to achieve stable RF signal transmission.

[0034] like Figure 4 and Figure 5 As shown, the shielding shell 10 has symmetrically arranged vertical ribs 101 for engaging the plastic shell 20 on two side walls perpendicular to the circuit board 1. The extension direction of the vertical ribs 101 is perpendicular to the insertion direction 40 of the board-end RF connector and the mating connector. At least one of the two side walls perpendicular to the circuit board 1 has a horizontal rib 102 perpendicular to the vertical ribs 101. The plastic shell 20 has corresponding vertical grooves 201 for engaging the vertical ribs 101 and horizontal grooves 202 for accommodating the horizontal ribs 102. The vertical ribs 101 and horizontal ribs 102 cooperate with the vertical grooves 201 and horizontal grooves 202 on the plastic shell 20, respectively, to prevent the plastic shell 20 from deflecting when subjected to left-right and up-down bias forces, thereby ensuring that the plastic shell 20 will not deflect under different bias forces and achieving a reliable fit between the plastic shell 20 and the RF transmission components.

[0035] In one implementation, such as Figure 3As shown, to ensure a reliable fit between the plastic shell 20 and the radio frequency transmission component, horizontal ribs 102 perpendicular to the vertical ribs 101 are preferably provided on both side walls of the shielding shell 10 perpendicular to the circuit board 1. During the insertion of the plastic shell 20 into the radio frequency transmission component, the horizontal ribs 102 and the horizontal grooves 202 cooperate to guide the insertion of the plastic shell 20. After insertion, the vertical ribs 101 snap into the vertical grooves 201, achieving a snap-fit ​​fit between the plastic shell 20 and the radio frequency transmission component. Specifically, the cross-section of the horizontal ribs 102 is rectangular, and the shape of the horizontal grooves 202 matches the shape of the horizontal ribs 102. After the horizontal ribs 102 are inserted into the horizontal grooves 202, the side walls of the horizontal ribs 102 and the horizontal grooves 202 cooperate with each other, ensuring that the plastic shell 20 is protected against deflection when subjected to lateral bias forces in the vertical direction. To prevent interference between the vertical ribs 101 and the horizontal ribs 102, the horizontal ribs 102 and the vertical ribs 101 are discontinuously arranged, forming a structure similar to a T-shape.

[0036] In one implementation, such as Figures 4-6 As shown, the shielding shell 10 has a top short rib 103 on its side wall parallel to the circuit board 1, and the plastic shell 20 has a corresponding short groove 203 for engaging the top short rib 103. After the top short rib 103 and the short groove 203 are engaged, on the one hand, the holding force on the plastic shell 20 can be increased, and on the other hand, the anti-deflection capability of the plastic shell 20 can be increased when the plastic shell 20 is subjected to lateral bias force.

[0037] Furthermore, the sides of the top short rib 103, horizontal rib 102, and vertical rib 101 facing the plastic shell 20 are all inclined surfaces 104 with a guiding function, while the side away from the plastic shell 20 is a vertical surface 105 perpendicular to the corresponding side wall of the shielding shell 10. Since the structures on both sides of the top short rib 103, horizontal rib 102, and vertical rib 101 are the same, only the top short rib 103 is used as an example to illustrate the structure of the above three components. Please refer to [link / reference] for details. Figure 6 During the insertion of the plastic shell 20 into the RF transmission assembly, the inclined surfaces 104 of the three components act as guides. After insertion, the vertical surfaces 105 of the three components engage with the inner walls of the short groove 203, horizontal groove 202, and vertical groove 201 on the plastic shell 20 to prevent the plastic shell 20 from falling off the RF transmission assembly. Furthermore, to reduce the manufacturing cost of the shielding shell 10, the shielding shell 10, the top short rib 103, the horizontal rib 102, and the vertical rib 101 are preferably integrally injection molded.

[0038] In one embodiment, at least one of the inner wall of the plastic shell 20 and the outer wall of the shielding shell 10 is provided with a plurality of protrusions 106 spaced apart along the circumferential direction, preferably provided on the outer wall of the shielding shell 10. Please refer to [link to specific details]. Figure 4During the process of installing the RF transmission component into the plastic housing 20, the protrusion 106 causes hard interference between the plastic housing 20 and the shielding housing 10, resulting in a more stable connection.

[0039] In one implementation, such as Figures 3-5 As shown, the outer wall of the shielding shell 10 is formed with positioning ribs 107 arranged along the axial direction of the shielding shell 10. The end of the plastic shell 20 facing the shielding shell 10 is recessed inward to form a positioning notch 204 that slides with the positioning ribs. During the process of the plastic shell 20 being installed into the shielding shell 10, the positioning notch 204 and the positioning ribs 107 slide with each other to achieve the positioning of the assembly of the two.

[0040] This utility model further provides a connector assembly, including a circuit board 1, the aforementioned board-side RF connector 2, and a mating connector (not shown in the figure) that mates with the board-side RF connector 2. The board-side RF connector 2 is soldered to the circuit board 1 to achieve stable RF signal transmission. As mentioned above, the board-side RF connector 2 has mutually perpendicular vertical ribs 101 and horizontal ribs 102 on the side wall of the circuit board 1. The vertical ribs 101 and horizontal ribs 102 respectively mate with vertical grooves 201 and horizontal grooves 202 on the plastic shell 20 to prevent the plastic shell 20 from deflecting when subjected to left-right and up-down bias forces, thereby ensuring that the plastic shell 20 will not deflect under different directional bias forces and achieving reliable mating between the plastic shell 20 and the RF transmission component. This prevents the plastic shell 20 from deflecting or falling off under bias forces, thus affecting the mating of the connector assembly.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
