The outer side of the enclosure is provided with a limiting step, which surrounds the enclosure and the top surface of the limiting step supports the first extension, the second extension and the connecting edge.

[0010] Optionally, the length of the first extension along the length direction of the first side plate is less than half the length of the first side plate, and the length of the second extension along the length direction of the second side plate is less than half the length of the second side plate.

[0011] Optionally, the thickness of the first extension is the same as the thickness of the first side plate, and the thickness of the second extension is the same as the thickness of the second side plate; the maximum height of the first extension is the same as the maximum height of the first side plate, and the maximum height of the second extension is the same as the maximum height of the second side plate.

[0012] Optionally, the first through structure is a groove, the groove having an opening facing away from the bottom plate; The female connector can be placed in the groove through the opening of the groove, and the outer side of the front end of the female connector is in contact with the groove sidewall.

[0013] Optionally, the second through structure is a through hole, and the cross-sectional shape of the through hole is adapted to the cross-sectional shape of the front end of the plug-in female.

The top plate extends downward in a back-to-forehead direction, and the connecting plate is inclined along with the top plate.

[0017] This invention provides a sound card in which a headphone jack-equipped female connector is fixed to a top plate via a connecting plate. A first extension extending towards the bottom plate is formed on one side of the front end of the top cover. The first extension is located on the outer side of the front sidewall of the enclosure. The front end of the female connector passes sequentially through a first through structure of the enclosure and a second through structure of the first extension, exposing the headphone jack within the housing. One end of the front sidewall of the enclosure, near the top plate, is inserted into a first gap between the inner side of the first extension and the front side of the connecting plate. The front sidewall of the enclosure abuts against the first extension and the connecting plate, thereby blocking either the connecting plate or the first extension when the headphone jack is plugged in or unplugged. This limits the position of the female connector during headphone plugging and unplugging, reducing deformation of the housing caused by frequent headphone plugging and unplugging. The first extension is provided in accordance with the first through structure on the enclosure. The first extension and the front sidewall of the enclosure overlap in the opening direction of the headphone hole. Thus, the shell near the headphone hole, where frequent plugging and unplugging actions occur, is designed with a double-thickened structure to achieve a local reinforcement effect on the shell near the plug-in socket. This allows for reasonable buffering of the stress generated by the shell during the plugging and unplugging of the headphone terminals, thereby improving the structural stability of the shell.

Detailed Implementation

[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] One embodiment of this utility model provides a sound card, such as Figure 1 and Figure 2 As shown, it includes a housing 1, a connecting plate 2, and a plug-in female socket 3. The housing 1 includes a bottom shell 11 and a top cover 12 that covers the top of the bottom shell 11. The bottom shell 11 and the top cover 12 enclose a mounting cavity. The connecting plate 2 and the plug-in female socket 3 are disposed in the mounting cavity. Figure 1 The direction indicated by the middle arrow is the front and back direction. The side of housing 1 facing the user is the front, and the side of housing 1 facing away from the user is the back.

[0023] The bottom shell 11 includes a bottom plate 111 and a surrounding plate 112 arranged around the bottom plate 111. The front side wall of the surrounding plate 112 is provided with a first through structure 13 that runs through the front and rear directions. The top cover 12 includes a top plate 121 and a first extension 122. The top plate 121 and the bottom plate 111 are arranged opposite each other along the height direction of the shell 1. One front end of the top plate 121 extends toward the bottom plate 111 to form the first extension 122. The first extension 122 is located on the outside of the front side wall of the surrounding plate 112 and is provided corresponding to the first through structure 13. The first extension 122 is provided with a second through structure 14 that runs through the front and rear directions.

[0024] The connecting plate 2 is fixed to the side of the top plate 121 facing the bottom plate 111. There is a first gap between the front side of the connecting plate 2 and the inner side of the first extension 122. The front side wall of the enclosure 112 near the top plate 121 is inserted into the first gap and abuts against the connecting plate 2 and the first extension 122.

[0025] The plug-in female socket 3 is fixed to the connecting plate 2. The front end of the plug-in female socket 3 has an earphone hole 31. The front end of the plug-in female socket 3 passes through the first through structure 13 and the second through structure 14 in sequence to expose the earphone hole 31 on the front side of the housing 1, so that the user can frequently insert the earphone terminal into the earphone hole 31 or pull the earphone terminal out of the earphone hole 31 from the front side of the housing 1.

[0026] Specifically, the first extension 122 is provided corresponding to the first through structure 13 on the enclosure 112. The first extension 122 and the front sidewall of the enclosure 112 overlap in the opening direction of the headphone hole 31. Thus, the housing 1 near the headphone hole 31 where frequent plugging and unplugging actions occur is designed with a double-thickened structure to achieve a local reinforcement effect on the housing 1 near the plug-in socket 3, so as to reasonably buffer the stress generated by the action of plugging and unplugging the headphone terminal and improve the structural stability of the housing 1.

[0027] When the user pulls out the headphone terminal from the headphone jack 31, the plug-in female 3 tends to move in the pulling direction. Since the plug-in female 3 is fixed on the connecting plate 2, the end of the front side wall of the enclosure 112 near the top plate 121 is inserted into the first gap between the connecting plate 2 and the first extension 122. Therefore, the connecting plate 2 and the first extension 122 have the same tendency to move in the same direction as the plug-in female 3. The front side wall of the enclosure 112 can block the connecting plate 2 from moving outward, so as to achieve the limiting effect on the plug-in female 3 when the headphone terminal is pulled out, effectively reducing the deformation of the housing 1 caused by the action of pulling out the headphone terminal.

[0028] When the user inserts the headphone terminal into the headphone jack 31, the plug-in female 3 tends to move in the insertion direction. The connecting plate 2 and the first extension 122 have the same tendency to move in the same direction as the plug-in female 3. The front side wall of the enclosure 112 can block the first extension 122 from moving in the insertion direction, so as to realize the limiting effect on the plug-in female 3 when the headphone terminal is plugged in, effectively reducing the deformation of the housing 1 caused by the action of plugging in the headphone terminal.

[0029] In one embodiment, the enclosure 112 includes a first side plate 113, a second side plate 114, a third side plate 115, and a fourth side plate 116 connected end to end. The first side plate 113 and the third side plate 115 are arranged opposite each other in the front-back direction, and the third side plate 115 and the fourth side plate 116 are arranged opposite each other in the left-right direction. The first through structure 13 is disposed at the end of the first side plate 113 near the second side plate 114.

[0030] The top cover 12 also includes a second extension 123. The front end of the side of the top plate 121 corresponding to the second side plate 114 extends toward the bottom plate 111 to form the second extension 123. The first extension 122 and the second extension 123 are connected to further enhance the structural strength of the top cover 12 near the plug-in female 3.

[0031] In one embodiment, the female connector 3 is fixed to the connecting plate 2 by screws.

[0032] In one embodiment, such as Figure 2 As shown, the first side plate 113 and the third side plate 115 are arranged in parallel and spaced apart, and the second side plate 114 and the fourth side plate 116 are arranged in parallel and spaced apart, to form a square enclosure 112.

[0033] In one embodiment, such as Figure 2 As shown, a connecting edge 124 extending toward the bottom plate 111 is formed on the outer periphery of the top plate 121. The height of the connecting edge 124 is less than the height of the first extension 122 and the height of the second extension 123.

[0034] A limiting step 117 is provided on the outer side of the enclosure 112. The limiting step 117 is arranged around the enclosure 112, and the top surface of the limiting step 117 can support the first extension 122, the second extension 123 and the connecting edge 124.

[0035] When the top cover 12 is placed on the bottom shell 11, the limiting step 117 can pre-position the top cover 12, making it easier for the top cover 12 to be connected to the bottom shell 11 via a connector. Specifically, the top cover 12 and the bottom shell 11 are connected by screws.

[0036] In one embodiment, the first extension 122 transitions to the connection along an arc 124, and the second extension 123 transitions to the connection along an arc 124.

[0037] In one embodiment, such as Figure 2 As shown, the length of the first extension 122 extending along the length direction of the first side plate 113 is less than half the length of the first side plate 113, and the length of the second extension 123 extending along the length direction of the second side plate 114 is less than half the length of the second side plate 114, so as to reduce the weight and processing cost of the top cover 12 while enhancing the structural strength of the top cover 12.

[0038] In one embodiment, such as Figure 3 and Figure 4 As shown, the thickness of the first extension 122 is the same as the thickness of the first side plate 113, and the thickness of the second extension 123 is the same as the thickness of the second side plate 114.

[0039] The maximum height of the first extension 122 is the same as the maximum height of the first side plate 113, and the maximum height of the second extension 123 is the same as the maximum height of the second side plate 114.

[0040] In one embodiment, the bottom surface of the first extension 122 and the bottom surface of the second extension 123 are on the same plane.

[0041] In one embodiment, such as Figure 2 As shown, the first through structure 13 is a groove with an opening facing away from the bottom plate 111.

[0042] The female connector 3 can be placed in the groove through the opening of the groove, and the outer side of the front end of the female connector 3 can fit against the groove sidewall to limit the radial movement of the female connector 3.

[0043] Since the groove has an opening facing away from the base plate 111, the top cover 12, the connecting plate 2 and the plug-in female 3 can be assembled together in the space outside the base shell 11 first, and then the top cover 12 is placed down on the base shell 11. As the closing action is performed, the plug-in female 3 is placed in the groove, which facilitates the assembly of the sound card and improves the assembly efficiency.

[0044] In other embodiments, the first through structure 13 can be a round hole. When assembling the sound card, the plug-in female 3 is first fixed on the connecting plate 2, and then the connecting plate 2 is placed inside the bottom shell 11 so that the front end of the plug-in female 3 passes outward through the round hole. Finally, the second through structure 14 on the top cover 12 is fitted onto the front end of the plug-in female 3, the top cover 12 is closed on the bottom shell 11, and screws are installed from the top surface of the top cover 12 downward to connect the connecting plate 2.

[0045] In one embodiment, such as Figure 2 As shown, there are two female connectors 3. The two female connectors 3 are distributed at intervals along the length direction of the first side plate 113. The diameter of the earphone hole 31 formed at the front end of the two female connectors 3 is different. Correspondingly, two first through structures 13 are provided on the first side plate 113 of the enclosure 112. The two first through structures 13 extend along the length direction of the first side plate 113. Two second through structures 14 are provided on the first extension 122. The two first through structures 13 are connected to the two second through structures 14 in a one-to-one correspondence. The two female connectors 3 pass through the corresponding first through structure 13 and second through structure 14 respectively.

[0046] In one embodiment, the second through structure 14 is a through hole, the cross-sectional shape of which is adapted to the cross-sectional shape of the front end of the plug-in female 3, so as to use the hole wall of the through hole to radially limit the front end of the plug-in female 3, restrict the radial movement of the plug-in female 3, and improve the stability of the plug-in female 3.

[0047] In other embodiments, the second through structure 14 can be a through groove with an opening that penetrates the bottom surface of the first extension 122, and the sidewall of the through groove is in contact with the outer surface of the front end of the plug-in female 3.

[0048] In one embodiment, such as Figure 3 As shown, the outer dimensions of the connecting plate 2 are the same as the outer dimensions of the top opening of the enclosure 112. Each side of the connecting plate 2 abuts against the corresponding inner side of the enclosure 112, so as to limit the connecting plate 2 in various directions of the horizontal plane by using the enclosure 112 to improve the stability of the connecting plate 2 in the installation cavity.

[0049] In one embodiment, such as Figure 2 and Figure 4 As shown, multiple support platforms 118 are provided on the inner side of the enclosure 112. The multiple support platforms 118 are distributed around the enclosure 112 at intervals, and the multiple support platforms 118 together support the connecting plate 2.

[0050] In one embodiment, such as Figure 1 and Figure 2 As shown, the top plate 121 is provided with a button mounting hole 125 and a knob mounting hole 126. A button 4 is installed in the button mounting hole 125 and a knob 5 is installed in the knob mounting hole 126. The top plate 121 extends downward in a back-to-forehead direction. The connecting plate 2 is tilted along with the top plate 121 so that the button 4 and knob 5 on the top plate 121 face the user, making it convenient for the user to operate the button 4 and knob 5.

[0051] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
