Technical Field

[0001] This utility model belongs to the field of high-frequency connector technology, specifically relating to a shielding cover with a heat dissipation structure and a high-frequency connector. Background Technology

[0002] The primary function of connectors is to transmit electrical signals between two electrical devices. At high frequencies, connector attenuation and phase delay become more significant, affecting signal transmission quality. Furthermore, connectors are more susceptible to external interference at high frequencies, necessitating the use of shielding technology to reduce their sensitivity to such interference.

[0003] However, existing connector housings often directly attach the shielding cover to the spring clips. After prolonged use, the shielding cover is prone to loosening, resulting in a decrease in shielding effectiveness. Furthermore, once installed, it is inconvenient to remove, replace, or recycle the shielding cover, causing inconvenience. Therefore, there is an urgent need for a shielding cover and high-frequency connector with a heat dissipation structure to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a shielding cover and a high-frequency connector with a heat dissipation structure, so as to solve the problem mentioned in the background art that the existing connector shell is often directly connected to the shielding cover by spring clips, which easily causes the shielding cover to loosen after long-term use, and is inconvenient to remove after installation, and is inconvenient to replace or recycle the shielding cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shielding cover and high-frequency connector with a heat dissipation structure, comprising a shell, a cover plate, a heat dissipation structure, and a fixing structure. The top of the shell is slidably connected to the cover plate. The heat dissipation structure includes heat dissipation fins. The bottom of the heat dissipation fins is fixedly connected to a heat spreader plate. The four corners of the heat spreader plate are fixedly connected to the top of the cover plate by fixing rivets. The fixing structure includes a connecting rod and a rotating shaft. The bottom of the connecting rod is fixedly connected to two insert rods. The left and right sides of the cover plate are provided with protrusions. The insert rods are inserted into the protrusions. The front and rear ends of the bottom of the connecting rod are fixedly connected to limiting plates. The left and right ends of the cover plate are rotatably connected to the rotating shaft. The outer walls of the front and rear ends of the rotating shaft are fixedly connected to rotating rods. The bottom outer wall of the rotating rod is fixedly connected to insert blocks. The insert blocks are snapped into the left and right sides of the shell.

[0006] Preferably, spring pieces are provided on both the left and right sides of the top of the cover plate, and the top of the connecting rod abuts against the outer wall of the spring piece.

[0007] Preferably, the heat dissipation fins are welded to the top of the heat spreader.

[0008] Preferably, both the spring and the protrusion are trapezoidal in shape, and the spring has a certain degree of elasticity.

[0009] Preferably, a pressing plate is fixedly connected to the right side of the rotating rod, and the surface of the pressing plate is provided with an anti-slip coating.

[0010] Preferably, the bottom of the limiting plate is provided with an inclined surface, and the bottom of the limiting plate is attached to the outer wall of the pressing plate.

[0011] Preferably, the bottom of the insert block is provided with a slope, and the left and right sides of the outer shell are provided with slots, the size and position of which correspond to the insert block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This shielding cover with a heat dissipation structure and high-frequency connector has a fixing structure. When the cover plate needs to be installed on the outer shell, the cover plate is clipped onto the outer shell and pressed down. The bottom of the insert block is squeezed and rotates outward. When the cover plate is pressed all the way down, the bottom end of the rotating rod is pressed, so that the insert block is clipped into the slot of the outer shell. The connecting rod is inserted into the side of the cover plate. The spring is squeezed and deformed, so that the insert rod is inserted into the protrusion. The limiting plate is inserted between the pressing plate and the outer wall of the cover plate, so that the limiting plate abuts against the pressing plate, preventing the rotating rod from rotating. At this time, the spring pops up to fix the position of the connecting rod. When the cover plate needs to be removed, the connecting rod is pulled out and the pressing plate is pressed so that the insert block is no longer clipped into the outer shell, and the cover plate can be pulled out. The fixing structure facilitates the quick installation and removal of the cover plate, improves the efficiency of the installation and removal of the cover plate, facilitates the replacement or reuse of the cover plate, and is convenient to use.

[0014] 2. The shielding cover and high-frequency connector with heat dissipation structure are equipped with heat dissipation structure. The heat dissipation fins and heat spreader are fixed to the cover plate by fixing rivets. The heat spreader can absorb the heat of the cover plate and distribute the heat evenly. The heat spreader transfers the heat to the heat dissipation fins. The heat dissipation fins can dissipate the heat in a passive way. The heat dissipation structure can dissipate heat from the cover plate, improve the heat dissipation efficiency of the cover plate and facilitate use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a shielding cover and high-frequency connector with a heat dissipation structure, including a housing 1, a cover plate 2, a heat dissipation structure 3, and a fixing structure 4. The top of the housing 1 is slidably connected to the cover plate 2. The heat dissipation structure 3 includes heat dissipation fins 31, and the bottom of the heat dissipation fins 31 is fixedly connected to a heat spreader 32. The four corners of the heat spreader 32 are fixedly connected to the top of the cover plate 2 by fixing rivets 33. The fixing structure 4 includes a connecting rod 43 and a rotating shaft 46. The bottom of the connecting rod 43 is fixedly connected to two insert rods 45. The left and right sides of the cover plate 2 are... Both sides are provided with protrusions 42, and the insertion rod 45 is inserted into the protrusions 42. The front and rear ends of the bottom of the connecting rod 43 are fixedly connected to the limiting plate 44. The left and right ends of the cover plate 2 are rotatably connected to the rotating shaft 46. The outer walls of the front and rear ends of the rotating shaft 46 are fixedly connected to the rotating rod 47. The bottom outer wall of the rotating rod 47 is fixedly connected to the insertion block 49. The insertion block 49 is snapped into the left and right sides of the outer shell 1. The fixing structure 4 facilitates the quick installation and removal of the cover plate 2, improves the efficiency of the installation and removal of the cover plate 2, and facilitates the replacement or reuse of the cover plate 2.

[0023] Furthermore, spring pieces 41 are provided on both the left and right sides of the top of the cover plate 2. The top of the connecting rod 43 abuts against the outer wall of the spring piece 41. Both the spring piece 41 and the protrusion 42 are trapezoidal. The spring piece 41 has a certain elasticity. When the connecting rod 43 is inserted into the side of the cover plate 2, the spring piece 41 is deformed by compression, so that the insert rod 45 is inserted into the protrusion 42. The limiting plate 44 is inserted between the pressing plate 48 and the outer wall of the cover plate 2, so that the limiting plate 44 abuts against the pressing plate 48. The spring piece 41 springs up to fix the position of the connecting rod 43.

[0024] Furthermore, the heat dissipation fins 31 are welded to the top of the heat spreader 32. The heat spreader 32 can absorb the heat from the cover plate 2 and distribute the heat evenly. The heat spreader 32 transfers the heat to the heat dissipation fins 31, and the heat can be dissipated by the heat dissipation fins 31 in a passive heat dissipation manner.

[0025] Furthermore, a pressing plate 48 is fixedly connected to the right side of the rotating rod 47. The surface of the pressing plate 48 is provided with an anti-slip coating to prevent slippage when pressing the pressing plate 48, making the pressing plate 48 easier to press.

[0026] Furthermore, the bottom of the limiting plate 44 is provided with an inclined surface, and the bottom of the limiting plate 44 is attached to the outer wall of the pressing plate 48. The limiting plate 44 is inserted between the pressing plate 48 and the outer wall of the cover plate 2, so that the limiting plate 44 abuts against the pressing plate 48, preventing the rotating rod 47 from rotating.

[0027] Furthermore, the bottom of the insert 49 is provided with a slope, and slots are provided on both the left and right sides of the outer shell 1. The size and position of the slots correspond to the insert 49. The insert 49 locks into the slots of the outer shell 1, thereby fixing the position of the cover plate 2 and completing the installation of the outer shell 1 and the cover plate 2.

[0028] Working principle: In use, when the cover plate 2 needs to be installed on the outer shell 1, the cover plate 2 is snapped onto the outer shell 1 and pressed down. The bottom of the insert block 49 is squeezed and rotates outward. After the cover plate 2 is pressed all the way down, the bottom end of the rotating rod 47 is pressed down, so that the insert block 49 is snapped into the slot of the outer shell 1. The connecting rod 43 is inserted into the side of the cover plate 2. The spring piece 41 is squeezed and deformed, so that the insert rod 45 is inserted into the protrusion 42. The limiting plate 44 is inserted between the pressing plate 48 and the outer wall of the cover plate 2, so that the limiting plate 44 abuts against the pressing plate 48, preventing the rotating rod 47 from rotating. At this time, the spring piece 41 pops up to fix the position of the connecting rod 43. When it is necessary to remove the cover plate 2, the connecting rod 43 is pulled out. Press the pressing plate 48 to remove the insert 49 from the outer casing 1, and the cover plate 2 can be pulled out. The fixing structure 4 facilitates quick installation and removal of the cover plate 2, improving the efficiency of installation and removal, and making it easy to replace or reuse the cover plate 2. The heat dissipation fins 31 and the heat spreader 32 are fixed to the cover plate 2 by the fixing rivets 33. The heat spreader 32 can absorb the heat of the cover plate 2 and distribute the heat evenly. The heat spreader 32 transfers the heat to the heat dissipation fins 31, and the heat dissipation fins 31 can dissipate the heat in a passive way. The heat dissipation structure 3 can dissipate heat from the cover plate 2, improving the heat dissipation efficiency of the cover plate 2 and making it easy to use.
