Among the several side walls 212 of the lower cover 21, the first side wall 214 is located on the outermost side of the front side, and the first side wall 214 is provided with a fourth notch 2141 corresponding to each socket 3. When the upper cover 11 and the lower cover 21 are covered up and down, the fourth notch 2141 and the corresponding first notch 1141 are aligned up and down to form the aforementioned plug-in interface 102. The inner wall surface of the side wall 212 located at the fourth notch 2141 is provided with a lower narrow groove 2142 formed by a downward depression, and the inner wall surface of the side wall 112 located at the first notch 1141 is provided with an upper narrow groove 1142 formed by an upward depression. Fig.12 As shown, when the upper cover 11 and the lower cover 21 are closed together, the lower narrow groove 2142 and the upper narrow groove 1142 are aligned up and down to form a circle of waterproof groove 103. The waterproof groove 103 is arranged in a circle along the inner wall of the upper cover 11 and the lower cover 21 at the plug interface 102, and the waterproof groove 103 is located on the front side of the plug-in surface 31 of the socket 3.

[0083] refer to Fig.13 As shown, the outer side of the plug 71 is covered with a rubber-coated portion 73, which is a soft plastic with a certain elasticity. The rubber-coated portion 73 is located at one end of the plug 71 and is provided with a circle of convex ribs 731 along its surface. When the plug 71 is inserted into the plug interface 102, the convex ribs 731 are inserted into the waterproof groove 103, forming a sealing fit with the waterproof groove 103, playing a waterproof role, and preventing water vapor from entering the socket 3 from the gap between the plug interface 102 and the plug 71, thereby affecting the electrical connection between the socket 3 and the plug 71.

[0084] As a simple replacement, the rib 731 may also be in other forms, such as a circle of sealing ring (not shown) fixedly mounted. By providing a circle of receiving grooves (not shown) at the corresponding position of the plug 71 for receiving the sealing ring (not shown), when the plug 71 is inserted into the plug port 102, the sealing ring (not shown) is inserted into the waterproof groove 103 to form a sealed fit with the waterproof groove 103. In addition, when the plug 71 is not inserted into the socket 3, a sealing plug (not shown) can be used to plug into the plug port 102 to prevent water from entering the plug port 102.

[0085] refer to Figures 14 to 16 As shown, the substrate 41 of the mainboard 4 is also provided with a plurality of light sources, preferably LED lamp beads 45 are used as light sources, which can illuminate the four indicator light bars 132 on the panel 13. In this embodiment, four indicator light bars 132 are correspondingly provided on the panel 13. The indicator light bars 132 are in the shape of bars extending forward and backward and are arranged corresponding to each socket 3 along the forward and backward direction, and are respectively used to display the working status of the corresponding socket 3, such as whether the socket 3 is electrically connected to the electrode patch 300, whether the electrode patch 300 electrically connected to the socket 3 is faulty, etc. The four indicator light bars 132 are divided into two groups according to different lengths, corresponding to two groups of sockets 3 respectively, and the top wall 111 of the upper cover 11 is correspondingly provided with four light-transmitting grooves 113. The mainboard 4 lights up the corresponding LED lamp beads 45 according to the information fed back by each socket 3, and the lit LED lamp beads 45 illuminate the corresponding indicator light bars 132 through the corresponding light-transmitting grooves 113. The light-transmitting groove 113 is located in the area of ​​the sink 1111 , and the panel 13 covers the light-transmitting groove 113 , thereby preventing water vapor from entering the receiving cavity 101 through the light-transmitting groove 113 and contacting the mainboard 4 , thereby affecting the performance of the mainboard 4 .

[0086] The light-transmitting groove 113 of the top wall 111 is arranged in a strip shape extending in the front-back direction, and the width of the light-transmitting groove 113 is wider than the width of the indicator light bar 132 . Fig.15The cross-sectional view of the light-transmitting groove 113 along the front-back direction is shown. The light-transmitting groove 113 is through-through and generally in a V-shape with a larger top and a smaller bottom. The light-transmitting groove 113 has a front side wall 1131, a rear side wall 1132 and an opening 1133. The front side wall 1131 and the rear side wall 1132 are inclined and extend downward and toward each other. The opening 1133 is located between the bottom end of the front side wall 1131 and the bottom end of the rear side wall 1132. The top of the front side wall 1131 is also provided with a sinking portion 1134. Fig.16 , and Fig.15 Similarly, the adapter 100 is shown in a cross-sectional view of the light-transmitting groove 113 in the assembled state. The main board 4 is closely attached to the opening 1133 of the light-transmitting groove 113 of the upper cover 11 from the bottom side, so that the LED lamp beads 45 on the main board 4 completely protrude from the opening 1133 into the corresponding light-transmitting groove 113, and illuminate the indicator light bar 132 directly above it through the light-transmitting groove 113. Each LED lamp bead 45 is separated by protruding into the corresponding light-transmitting groove 113, which can prevent the light of the LED lamp bead 45 from entering other adjacent light-transmitting grooves 113 and illuminating other indicator light bars 132, so as to prevent the panel 13 from having light transmission.

[0087] Furthermore, the adapter 100 is provided with a light guide 14 in the light-transmitting groove 113 of the upper cover 11. The light guide 14 is made of a transparent material, preferably acrylic material. Figure 17 to Figure 18 As shown, the shape of the light guide 14 is basically matched with the light-transmitting groove 113, and is set in a plate shape that is larger at the top and smaller at the bottom and close to a triangle. The thickness of the light guide 14 is close to the width of the light-transmitting groove 113. The light guide 14 has a front side surface 141 that matches the front side wall 1131 of the light-transmitting groove 113 and a rear side surface 142 that matches the rear side wall 1132 of the light-transmitting groove 113. The front side surface 141 and the rear side surface 142 are both inclined surfaces. The bottom surface of the light guide 14 is provided with a refraction portion 143, and the refraction portion 143 is set in the shape of an arc groove that is concave toward the top of the light guide 14. The arc groove is set in the front-to-back direction and penetrates the light guide 14 in the left-to-right direction. The front and rear ends of the top of the light guide 14 are respectively provided with horizontally arranged extension portions 144. A light homogenizing portion 145 is provided in the middle of the top surface of the light guide 14. The light homogenizing portion 145 is provided in a V-shaped groove. The V-shaped groove is provided along the front-to-back direction and penetrates the light guide 14 along the left-to-right direction. The bottom angle of the V-shaped groove is 95° to 140°.

[0088] The light guide 14 is placed in the light-transmitting groove 113, the front side surface 141 of the light guide 14 is pressed against the front side wall 1131, the rear side surface 142 of the light guide 14 is pressed against the rear side wall 1132, and the extensions 144 of the light guide 14 at the front and rear ends of the top are supported on the bottom wall of the sinking part 1134 of the light-transmitting groove 113. The refraction part 143 at the bottom of the light guide 14 is aligned with the opening 1133, and the refraction part 143 is close to the LED lamp bead 45 and is located directly above the LED lamp bead 45. When the LED lamp bead 45 is lit, its light propagates to the refraction part 143 and is scattered along the light guide 14 to the indicator light bar 132 of the panel 13. The distance from the refraction portion 143 to the LED lamp bead 45 is 1-3 mm. If the distance is too close, it will affect the scattering effect of the light on the light guide 14; if the distance is too far, the intensity of the light scattered on the light guide 14 will be too weak. Taking all factors into consideration, 1-3 mm is a more reasonable distance.

[0089] The light guide 14 can concentrate the light of the LED lamp beads 45, effectively extend the penetration path of the light, and improve the scattering rate of the light. The refractive portion 143 at the bottom of the light guide 14 can further improve the light guiding effect of the light guide 14, and the light homogenizing portion 145 at the top of the light guide 14 can evenly distribute the light intensity on the light guide 14, preventing the problem of excessive light in the middle and weak light at the front and back ends, which can improve the display effect of the indicator light bar 132. The adapter 100 is also provided with a homogenizing film 15 in the light-transmitting groove 113 of the upper cover 11. The homogenizing film 15 covers the top surface of the light guide 14 and is located in the sunken portion 1134 of the light-transmitting groove 113, which can further improve the uniformity of light intensity and improve the display effect of the indicator light bar 132.

The four corners of the docking cavity 715 are respectively provided with arc-shaped chamfered corners 716, and when the plug 71 is docked with the socket 3, the transition portion 353 and the chamfered corners 716 cooperate with each other to form a guiding effect. In this embodiment, the curvature of the cross section of the transition portion 353 is 90°, and the curvature of the rounded corner 716 is also 90°.

[0094] The transition part 353 of the socket 3 includes an upper transition part 3531 located at two corners on the upper side of the plug surface 31 and a lower transition part 3532 located at two corners on the lower side of the plug surface 31. In order to prevent the plug 71 from being inserted upside down, the radius of the circle where the upper transition part 3531 is located is different from the radius of the circle where the lower transition part 3532 is located. The chamfered corner 716 includes an upper chamfered corner 7161 located at the upper side of the docking cavity 715 and a lower chamfered corner 7162 located at the lower side of the docking cavity 715. The radius of the circle where the upper chamfered corner 7161 is located is substantially consistent with the radius of the circle where the upper transition part 3531 is located, and the radius of the circle where the lower chamfered corner 7162 is located is substantially consistent with the radius of the circle where the lower transition part 3532 is located. In this embodiment, the radius of the circle where the upper transition portion 3531 is located is larger than the radius of the circle where the lower transition portion 3532 is located. If the plug 71 is reversed, the upper transition portion 3531 will block the inverted lower chamfer 7162 to prevent the plug 71 from being reversed and damaging the terminal 32 in the socket 3.
