Description

Technical Field

[0001] The utility model relates to the technical field of RF radio frequency modules, in particular to an RF radio frequency module which is easy to disassemble. Background Art

[0002] An RF module, or radio frequency wireless transmitter module, is an electronic component widely used in wireless communications. It modulates signals onto a radio frequency carrier and transmits them through an antenna, or demodulates received radio frequency signals to recover the original signal. An RF module typically consists of a housing and components such as an RF transceiver and power amplifier. The assembled RF transceiver and other components are typically installed and protected within the housing by removing covers on both sides of the housing.

[0003] In the prior art, the cover plates on both sides of the shell are usually threadedly connected to the shell body by multiple screws, that is, the cover plate on one side needs to be connected to the shell body by screws set at the four corners. When disassembling or installing components in the shell, the disassembly process is relatively troublesome, and when tightening multiple screws, the tightening force cannot be guaranteed to be the same, which can easily cause one side of the cover plate to warp and the like, and it cannot fit with the shell body. The cover plate is prone to deformation after long-term use. Utility Model Content

[0008] A single pressing unit includes a plug-in strip arranged in a vertical direction, the plug-in strip is adapted to the pressing installation slot, and the plug-in strip includes a plug-in strip body and a tip arranged at its lower end, the tip being able to be squeezed downwardly and tightly against the lower portion of the pressing installation slot;

[0009] The middle part of the cover plate is detachably connected to the mounting surface through a connecting piece.

[0010] By inserting the multiple pressing units on the cover plate into the pressing installation grooves accordingly and pressing the cover plate downward, the four corners of the cover plate can be squeezed tightly into the pressing installation grooves, and then the middle upper part of the cover plate is connected to the shell through the connecting piece to achieve the installation of the cover plate. Compared with the existing technology, the cover plate can be connected to the shell through only one connecting piece, which is convenient for disassembly and installation of the cover plate, and the cover plate will not warp.

[0011] In order to facilitate the insertion of the tip into the triangular groove and to enable it to continue to be pressed down and squeezed in the triangular groove, the maximum length of the tip along its width direction is set to be greater than the width of the insert body to prevent the insert body from affecting the tip's continued downward movement.

[0012] To facilitate the insertion of the tip and the plug-in body into the downward mounting groove, the thickness of the tip is smaller than the depth of the triangular groove. The side of the cover plate close to the mounting surface is the inner surface, and there is a gap between the lower part and the tip of the insert body and the inner surface.

[0013] To prevent the plug-in strip from escaping from the downward mounting groove, a stop rod is provided on the lower outer side of the vertical groove along its width direction. The lower part and the tip of the plug-in strip body can be inserted into the stop rod, and the outer surface of the stop rod is flush with the mounting surface.

[0014] In order to facilitate the rapid insertion of the lower portion and tip of the insert body onto the lever, the inner surface of the lever is an inclined surface that slopes inward from top to bottom, and the tip can slide over the inclined surface to move into the triangular groove. The inner side of the vertical groove has a vertically arranged bottom surface, and the minimum vertical distance between the inclined surface and the bottom surface is greater than the thickness of the tip.

[0015] To prevent the tip from shaking in the triangular groove, a removable rubber layer is provided on the inner side of the tip, and the sum of the thickness of the rubber layer and the tip is greater than the minimum vertical distance between the inclined surface and the bottom surface.

[0016] In order to facilitate the tip to continue to press down to a certain position when inserted into the triangular groove, thereby squeezing the tip tightly into the triangular groove, the lower end of the tip is a plane, and the vertical distance between the plane and the upper end surface of the tip is less than the height of the triangular groove.

[0017] The upper end of the vertical groove below has no opening. In order to simultaneously place the down-pressing unit into the down-pressing installation groove, the ratio of the length of the vertical groove to the length of the plug-in strip is 1.5-2. When the plug-in strip is installed in the down-pressing installation groove, it can continue to move downward.

[0018] The beneficial effects of the present utility model are:

[0019] The four corners of the inner surface of the cover are respectively provided with plug-in parts, which cooperate with the downward pressing installation grooves of the mounting surface. After the plug-in parts are installed in the vertical grooves, they are pressed down along the vertical grooves so that the gap between the lower part and the tip of the plug-in body and the inner surface can be inserted into the gear lever, preventing the plug-in parts from falling out of the downward pressing installation grooves; and the two sides of the tip along the width direction can be squeezed tightly into the triangular grooves when continuing to move downward, so that the four corners of the cover can be stably installed on one side of the housing;

[0020] In order to further stably install the tip in the triangular groove and prevent the tip from shaking in the triangular groove along its thickness direction, a rubber layer with flexibility and friction is provided on the inner side of the tip. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1As shown, an RF module that is easy to disassemble includes a shell 1. The shell 1 has openings on both sides along the length direction. The sides of the shell 1 where the two openings are located are both mounting surfaces 11. A cover plate 4 is detachably connected to the mounting surface 11, and two cover plates 4 are provided.

[0033] See also Figure 6 、 Figure 7 and Figure 8 As shown, each mounting surface 11 is provided with a downward pressing mounting groove 2 at its four corners, and the cover plate 4 is provided with a downward pressing unit that cooperates with the corresponding downward pressing mounting groove 2; the downward pressing mounting groove 2 includes a connected vertical groove 21 and a triangular groove 22, and the triangular groove 22 is located at the lower end of the vertical groove 21 arranged vertically.

[0034] See also Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a single downward pressing unit includes a vertically arranged plug-in strip 3 that fits within the downward pressing mounting groove 2. The plug-in strip 3 comprises a strip body 31 and a tip 32 at its lower end. The tip 32 is capable of being squeezed downwardly against the lower portion of the downward pressing mounting groove 2. To facilitate insertion of the tip 32 into the triangular groove 22 and to ensure continued downward compression, the maximum width of the tip 32 is greater than the width of the strip body 31, preventing the strip body 31 from interfering with the continued downward movement of the tip 32. To facilitate continued downward compression of the tip 32 within the triangular groove 22, thereby securing the tip 32 within the triangular groove 22, the lower end of the tip 32 is a flat surface 321. The vertical distance between the flat surface 321 and the upper end surface of the tip 32 is less than the height of the triangular groove 22.

[0035] See also Figure 8 As shown, the upper end of the upper vertical groove 21 can be set to have an opening to facilitate the installation of the upper plug-in strip, and the upper end of the lower vertical groove 21 has no opening. In order to simultaneously place the downward pressure unit into the downward pressure installation groove 2, the ratio of the length of the vertical groove 21 to the length of the plug-in strip 3 is 1.5-2. When the plug-in strip 3 is installed in the downward pressure installation groove 2, it can continue to move downward.

[0036] To facilitate insertion of the tip 32 and the connector body into the downward-pressing mounting groove 2, the thickness of the tip 32 is less than the depth of the triangular groove 22. The surface of the cover plate 4 closest to the mounting surface 11 is the inner surface 41. A gap exists between the lower portion and the tip 32 of the insert body 31 and the inner surface 41, meaning that the upper portion of the insert body 31 is connected to the inner surface 41 via a connecting piece 8. To prevent the connector 3 from escaping the downward-pressing mounting groove 2, a stopper 5 is provided along the lower, outer side of the vertical groove 21 along its width. The lower portion and the tip 32 of the insert body 31 can be inserted between the stopper 5 and the downward-pressing mounting groove 2. The stopper 5 acts as a position limiter for the connector. To prevent the outer surface of the lever from interfering with the cover plate 4, the outer surface of the stopper 5 is flush with the mounting surface 11.

[0037] See also Figure 1 As shown, when the connectors on the cover plate 4 are correspondingly inserted into the downward pressing installation groove 2, the cover plate 4 is limited in the up and down directions and along the length direction of the shell 1. In order to further fasten the cover plate 4 to the shell 1, the middle position of the upper part of the cover plate 4 is detachably connected to the mounting surface 11 through a connecting member 7. The connecting member 7 can be a connecting bolt. A threaded hole is provided in the upper middle position of the mounting surface 11. The connecting bolt is threadedly connected in the threaded hole, so that a cover plate 4 and the shell 1 only need to be connected by one connecting bolt, which is higher than the prior art which requires at least four bolts. The utility model can greatly improve the installation and disassembly efficiency of the cover plate 4.

[0038] The above structure can achieve the following function: by correspondingly inserting the multiple pressing units on the cover plate 4 into the pressing installation groove 2 and pressing the cover plate 4 downward, the four corners of the cover plate 4 can be squeezed tightly into the pressing installation groove 2, and then the middle upper part of the cover plate 4 is connected to the shell 1 through the connecting member 7 to realize the installation of the cover plate 4. Compared with the existing technology, the cover plate 4 can be connected to the shell 1 through only one connecting member 7, which is convenient for the disassembly and installation of the cover plate 4, and the cover plate 4 will not have warping.

[0039] To facilitate the rapid insertion of the lower portion of the insert body 31 and the tip 32 onto the lever 5, the inner surface of the lever 5 is an inclined surface 51 that slopes inward from top to bottom. The tip 32 can slide over the inclined surface 51 and move into the triangular groove 22. The inner side of the vertical groove 21 has a vertically arranged bottom surface 211. The minimum vertical distance between the inclined surface 51 and the bottom surface 211 is greater than the thickness of the tip 32.

[0040] See also Figure 4 and Figure 5As shown, when the connector strip 3 is manufactured, there will be gaps between the tip 32 and the triangular groove 22 on both sides along the thickness direction, causing the cover plate 4 to shake. In order to prevent the tip 32 from shaking in the triangular groove 22, a rubber layer 6 is detachably provided on the side of the tip 32 close to the inner surface 41. The sum of the thickness of the rubber layer 6 and the tip 32 is greater than the minimum vertical distance between the inclined surface 51 and the bottom surface 211, and one side of the rubber layer 6 can contact the inclined surface 51.
