DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] In the prior art, the electrode sheet interface of the junction box is connected by a male pin and a female pin through plugging and unplugging. The male pin and the female pin are arranged horizontally, resulting in a wider width of the junction box and a poor grip. The male pin in the middle is blocked by the male pins on the outside, and it is difficult for users to adjust the plugging and unplugging angle during the plugging and unplugging process, resulting in the male pin in the middle being difficult to bear force and prone to connection failures.

[0043] In order to solve the above technical problems, the present application provides a junction box, which can greatly reduce the width of the junction box, while improving the grip feel, so that the Type-C interface can be better plugged in and out, thereby effectively reducing the problem of connection failure and improving the reliability of the connection between the female connector and the male connector.

[0044] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a junction box 1, including a shell 11, a first circuit board 12, a plug-in female socket 13 and a plug-in male head 14, the shell 11 has a receiving cavity; the first circuit board 12 is arranged in the receiving cavity of the shell 11; the plug-in female socket 13 is arranged in the receiving cavity of the shell 11, and the plug-in female socket 13 is electrically connected to the first circuit board 12; and the plug-in male head 14 is used to plug with the plug-in female socket 13; wherein the plug-in female socket 13 and the plug-in male head 14 respectively adopt Type-C interfaces. The plug-in female socket 13 and the plug-in male head 14 respectively adopt Type-C interfaces, which can realize positive and negative insertion, and use the locking structure of Type-C to achieve plug-in position, which can effectively reduce the problem of connection failure and improve connection reliability.

[0045] Specifically, one end of the first circuit board 12 is electrically connected to the female connector 13, and the other end is connected to the electric field generating device. One end of the male connector 14 is connected to the electrode sheet, and the other end is used to plug into the female connector 13, thereby realizing the electrical connection between the therapeutic device and the electrode sheet.

[0046] The width direction y2 of the female connector 13 is parallel to the height direction y1 of the housing 11 .

[0047] It can be understood that by setting the width direction y2 of the female connector 13 to be parallel to the height direction y1 of the shell 11, that is, the female connector 13 and the male connector 14 are both arranged vertically, the width of the junction box 1 can be greatly reduced, while improving the grip feel and allowing the Type-C interface to be better plugged in and out, thereby effectively reducing the problem of connection failure and improving the reliability of the connection between the female connector 13 and the male connector 14.

[0048] There are multiple female connectors 13, which are arranged side by side in the accommodating cavity of the shell 11. There are also multiple female connectors 13 corresponding to the male connectors 14, which are arranged side by side. Each female connector 13 is installed on an independent second circuit board 131, and the second circuit board 131 is electrically connected to the first circuit board 12.

[0049] By vertically arranging the female connector 13 and the male connector 14, the distance between two adjacent male connectors 14 is shortened, and the male connector 14 in the middle is not easily blocked by the male connectors 14 on the outside. The user can conveniently adjust the plugging and unplugging angle of the male connector 14 during the plugging and unplugging process, thereby effectively reducing the problem of connection failure and further improving the reliability of the connection between the female connector 13 and the male connector 14.

[0050] In some embodiments, Figure 2As shown, the junction box 1 also includes a fixing component 15 arranged in the accommodating cavity, and the fixing component 15 includes a first fixing member 151, and the first fixing member 151 has a guide hole 1511. The guide hole 1511 is open at both ends, and one end thereof is aligned with the plug-in female socket 13. The guide hole 1511 guides the plug-in male plug 14 during the docking process between the plug-in male plug 14 and the plug-in female socket 13, so that the plug-in male plug 14 can be accurately inserted into the plug-in female socket 13; the guide hole 1511 is set to a flat hole corresponding to the shape of the plug-in female socket 13, and its length direction y3 is parallel to the height direction y1 of the shell 11.

[0051] It can be understood that the guide hole 1511 of the first fixing member 151 is aligned with the plug-in female socket 13. When the plug-in male head 14 needs to be plugged into the plug-in female socket 13, the plug-in male head 14 needs to first pass through the guide hole 1511, and the plug-in male head 14 is positioned through the guide hole 1511, thereby ensuring that the plug-in male head 14 can be accurately inserted into the plug-in female socket 13, further reducing the wear between the plug-in female socket 13 and the plug-in male head 14, and ensuring the reliability of the connection between the plug-in female socket 13 and the plug-in male head 14.

[0052] In some embodiments, Figure 3 As shown, the fixing assembly 15 also includes a second fixing member 152 for fixing the plug-in female socket 13, and the second fixing member 152 is detachably connected to the first fixing member 151; a first positioning groove 1512 for positioning the plug-in female socket 13 is provided on the side of the first fixing member 151 facing the second fixing member 152, and one end of the first positioning groove 1512 is docked with the corresponding guide hole 1511; the plug-in female socket 13 is installed in the first positioning groove 1512; the second fixing member 152 is covered on the first positioning groove 1512, and a second positioning groove 1521 for positioning the plug-in female socket 13 is provided on the side of the second fixing member 152 facing the first fixing member 151, and the first positioning groove 1512 and the second positioning groove 1521 constitute an installation space for positioning and installing the plug-in female socket 13.

[0053] In some embodiments, Figure 4 As shown, when the second fixing member 152 is installed on the first fixing member 151, there is a gap 1522 between the second fixing member 152 and the first fixing member 151, and the gap width is 0.1cm to 0.2cm. In a most preferred embodiment, the width of the gap 1522 is 0.15cm. The function of the gap 1522 is to prevent the long-term plugging and unplugging of the male connector 14 from causing tin cracks on the PCBA pad of the female connector 13, thereby reducing the probability of damage to the female connector 13.

[0054] In the embodiment of the present application, the second fixing member 152 is connected to the first fixing member 151 through a fastener (for example, a bolt), one side of the plug-in female socket 13 is located in the first positioning groove 1512, and the other side is located in the second positioning groove 1521, thereby realizing the positioning of the plug-in female socket 13, ensuring that the plug-in female socket 13 can be aligned with the guide hole 1511 of the first fixing member 151, and further ensuring that the plug-in male head 14 can be accurately inserted into the plug-in female socket 13.

[0055] The installation space is formed into a flat space corresponding to the shape of the female plug socket 13, and the length direction y4 of the installation space is parallel to the width direction y2 of the female plug socket 13. By arranging the female plug socket 13 vertically, the size of the installation space in its width direction can be reduced, thereby reducing the overall width of the junction box 1, making the junction box 1 easy to carry.

[0056] like Figure 3 and Figure 5 As shown, the first fixing member 151 is provided with a plurality of guide holes 1511 corresponding to the plurality of female connectors 13, and the plurality of guide holes 1511 are arranged in parallel; the plurality of guide holes 1511 are arranged along the width direction x1 of the housing 11; the first fixing member 151 is provided with a plurality of first positioning grooves 1512 corresponding to the plurality of guide holes 1511; the second fixing member 152 is provided with a plurality of second positioning grooves 1521 corresponding to the plurality of first positioning grooves 1512. It can be understood that the second fixing member 152 is assembled to the first fixing member 151, and the second positioning grooves 1521 correspond to the first positioning grooves 1512 one by one, and an installation space for installing the female connector 13 is formed between the two, and the plurality of installation spaces correspond to the plurality of guide holes 1511 one by one, respectively, so that the male connector 14 guided by the guide holes 1511 can be accurately inserted into the female connector 13.

It can be understood that the plug male connector 14 is plugged into the first fixing member 151, and the plug connection between the first boss 1513 and the first locking groove 141 or the plug connection between the second boss and the second locking groove can realize the limit of the plug male connector 14 on the first fixing member 151.

[0058] In some embodiments, Figure 3As shown, the housing 11 is composed of a first box body 111 and a second box body 112, which are arranged opposite to each other; the first box body 111 or the second box body 112 is provided with a slot for fixing the first fixing member 151. By covering the first box body 111 on the second box body 112, the housing 11 can be assembled and the first fixing member 151 can be positioned at the same time.

[0059] like Figure 3 and Figure 7 As shown, a third positioning groove 1111 for positioning the first fixing member 151 is provided on one side of the first box body 111 facing the second box body 112, and a fourth positioning groove 1121 for positioning the first fixing member 151 is provided on one side of the second box body 112 facing the first box body 111. The first fixing member 151 can be positioned by the third positioning groove 1111 and the fourth positioning groove 1121.

[0060] In some instances, such as Figure 2 As shown, a display screen 16 is installed on the housing 11. The junction box 1 in the embodiment of the present application is designed with a display screen 16, through which key information is synchronized, the user can check the operating status of the host at any time, which is more intuitive and has a better experience.

[0061] In some examples, a first mounting hole 1112 is formed in the first box body 111 , and a display screen 16 is embedded in the first mounting hole 1112 .

[0062] The display screen 16 includes an inner display screen 161 and an outer display screen 162. The outer display screen 162 is embedded in the first mounting hole 1112. The first mounting hole 1112 is located directly above the first circuit board 12. The junction box 1 also includes a display support 17. The display support 17 is located between the inner display screen 161 and the first circuit board 12, and is used to limit the display screen 16.

[0063] like Figure 2 As shown, the display support 17 includes a first mounting column 171 located on both sides thereof, and the display support 17 is fixedly connected to the first box body 111 through the first mounting column 171.

By setting the switch assembly 18, the first circuit board 12 can be turned on and off, thereby controlling the power on and off of the junction box 1.

[0065] Since the back clip of the existing junction box 1 is protruding, the back clip will hurt the wearer when wearing it close to the body, which results in poor user experience.

[0067] The receiving groove 1122 is formed by the second box body 112 being recessed inwardly. The receiving groove 1122 is located on one side of the receiving cavity and is used to support the first circuit board 12 .

[0068] like Figure 2 As shown, the elastic back clip 19 includes a clip body 191, a pin 192 and a torsion spring 193.

The clip body 191 is pressed against the second box body 112 to apply an external force, so that the clip body 191 rotates around the pin 192, thereby opening the elastic back clip 19, and the junction box 1 can be clamped on the human body for easy carrying. The clip body 191 can rotate and return to its original state under the torsion of the torsion spring 193.

[0069] like Fig. 9 and Fig.10 As shown, the second box body 112 has a first curved surface 1123, and the side of the clamping body 191 facing away from the second box body 112 is flush with the highest point of the first curved surface 1123, so that the overall volume of the junction box 1 is as small as possible and the comfort of the junction box 1 when it is clamped on the human body is ensured; and / or, one end of the clamping body 191 extends away from the second box body 112 and protrudes from the first curved surface 1123 of the second box body 112, and the user presses the protruding end of the clamping body 191 to open the clamping body 191, which is convenient for the user to operate; and / or, the side of the clamping body 191 facing the second box body 112 is provided with anti-slip ribs 1911 and / or anti-slip teeth 1912 to increase friction.
