Description

[0001] This application claims the priority of a Chinese patent application with the application number 202411668807.2 and the invention title "Socket" filed with the Patent Office of the State Intellectual Property Office of China on November 20, 2024, the entire content of which is incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the technical field of electrical appliances, and particularly relates to a socket. Background Art

[0003] With the continuous enrichment of electrical appliances, during the use of sockets by users, the situation of socket overload may occur. To improve the safety of sockets, an overload protector is added to the socket, and the overload protector is connected to the internal circuit of the socket. When an overload phenomenon occurs in the socket, the overload protector cuts off the internal circuit of the socket, thereby avoiding danger.

[0004] In the related art, some sockets are equipped with switches, and users can control the on / off of the socket by pressing the switch. When adding an overload protector to a socket with a switch, it is necessary to connect the switch and the overload protector together through a cable, which makes the cable routing inside the socket complex. Moreover, the space required for the overload protector and the newly added cable is relatively large, which requires improving the socket housing of the socket, increasing the cost of the socket.

[0076] Through the above-mentioned drawings, the specific embodiments of the present disclosure have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure in any way, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0077] To make the objectives, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0078] In recent years, with the continuous improvement of living standards, users' demands for electrical equipment have also been continuously enriched. When using a socket, users often encounter the phenomenon of socket overload. After the socket is overloaded, in severe cases, it may cause a fire, which is very dangerous. Therefore, to improve the safety of the socket, an overload protector is added to the socket. The overload protector is connected to the internal circuit of the socket. When the socket is overloaded, the overload protector cuts off the internal circuit of the socket, thus avoiding danger.

[0079] In related technologies, some sockets are equipped with switches, and users can control the power on and off of the socket by pressing the switch button. When adding an overload protector to a socket with a switch, in one solution, the switch and the overload protector are connected together by a cable, which makes the cable routing inside the socket complicated. Moreover, the space required for the overload protector and the new cable is relatively large, which requires improving the socket housing of the socket, increasing the cost of the socket. In another solution, the switch and the overload protector are integrated together. However, this is not conducive to independently replacing the switch and the overload protector; when one of them is damaged, both need to be replaced together.

[0080] In addition, the reset button of the overload protector in related technologies is often exposed on the side of the socket. On the one hand, the position of the reset button is not prominent, which is not conducive to reminding the user to press the reset button after the socket is overloaded. On the other hand, sometimes the side of the socket is placed against the wall, which may cause the reset button not to pop out under the block of the wall after the socket is overloaded, which is very dangerous.

[0081] In view of the above technical problems, the embodiments of the present disclosure provide a socket. Figure 1 The external view of the socket is shown. Figure 2 and Figure 3 The schematic diagram of the internal structure of the socket is shown. As Figures 1 - 3 shown, the socket includes a socket housing 1, a plug-in component 2, a switch 3 and an overload protector 4. The plug-in component 2, the switch 3 and the overload protector 4 are fixed to the socket housing 1. Figures 4 - 6 The schematic diagram of the switch 3 and the overload protector 4 is shown. As Figures 3 - 6As shown, the switch 3 includes a first conductive sheet 31 and a second conductive sheet 32, and the switch 3 is used to control the on / off of the circuit between the first conductive sheet 31 and the second conductive sheet 32. The overload protector 4 includes a third conductive sheet 43 and a fourth conductive sheet 44. When the overload protector 4 is overloaded, the circuit between the third conductive sheet 43 and the fourth conductive sheet 44 is disconnected. The third conductive sheet 43 is in contact with and connected to the second conductive sheet 32. One of the first conductive sheet 31 and the fourth conductive sheet 44 is connected to the power supply line, and the other is electrically connected to the plug-in component 2.

[0082] Among them, as Figure 1 shown, the socket housing 1 includes a socket bottom case 11 and a socket upper cover 12. The socket upper cover 12 includes a jack surface. The plug-in component 2 is used to dock with the plug, and the plug-in component 2 includes a protection door component and a corresponding socket part. Each plug-in component 2 is used to dock with at least one plug, and the plug is a two-pole plug or a three-pole plug. The switch 3 includes a switch button 33, and the switch button 33 is exposed on the jack surface of the socket housing 1, so that the user can control the on / off between the first conductive sheet 31 and the second conductive sheet 32 by pressing the switch button 33. The embodiment of the present disclosure does not limit the implementation manner of the circuit between the first conductive sheet 31 and the second conductive sheet 32. For example, the relevant structure of the existing switch 3 can be adopted.

[0083] The technical solution provided by the embodiment of the present disclosure, as Figure 3 shown, when the socket is overloaded, the circuit between the third conductive sheet 43 and the fourth conductive sheet 44 of the overload protector 4 is disconnected, so that the circuit between the plug-in component 2 of the socket and the power supply line 5 is disconnected. Thus, the possibility of danger occurring in the socket is reduced.

[0084] Moreover, by setting the third conductive sheet 43 of the overload protector 4 to be in direct contact with and electrically connected to the second conductive sheet 32 of the switch 3, rather than being connected by a cable, the complexity of the cable routing inside the socket is reduced. And this also makes the distance between the overload protector 4 and the switch 3 relatively close, and the two are relatively compact, so the space required for the overload protector 4 and the switch 3 is reduced, so that it is not necessary to increase the socket housing 1, and the newly added overload protector 4 can also be accommodated in the socket housing 1, reducing the cost of the socket. In addition, by setting the overload protector 4 and the switch 3 as two independent devices, rather than being integrated together, after one of the overload protector 4 and the switch 3 is damaged, only the damaged device can be replaced, without replacing both of them together, which also reduces the cost of the socket.

[0085] In some examples, as Figure 3As shown, the power cord 5 includes a first-pole cable 51 and a second-pole cable 52; the plug-in component 2 includes a first-pole socket 21 and a second-pole socket 22. Among them, the above-mentioned first pole can be the L pole, and the above-mentioned second pole can be the N pole. One of the first conductive sheet 31 and the fourth conductive sheet 44 is connected to the first-pole cable 51, and the other is electrically connected to the first-pole socket 21.

[0086] Among them, the plug-in component 2 can include a first-pole copper bar, and the first-pole socket 21 is arranged on the first-pole copper bar. Then, the first conductive sheet 31 or the fourth conductive sheet 44 can be electrically connected to the first-pole socket 21 by directly contacting the first-pole copper bar.

[0087] The embodiments of the present disclosure do not limit the arrangement positions of the switch 3 and the overload protector 4 inside the socket housing 1. In some examples, such as Figure 2 and Figure 3 As shown, along the length direction X of the socket, the overload protector 4 is arranged between the plug-in component 2 and the switch 3; then the first conductive sheet 31 is connected to the power cord 5, and the fourth conductive sheet 44 is electrically connected to the plug-in component 2. In this way, the space between the plug-in component 2 and the switch 3 is fully utilized, and the space utilization rate inside the socket housing 1 is improved. Moreover, it is not necessary to improve other parts of the socket housing 1 or make too much improvement, reducing the cost. It should be noted that if the overload protector 4 can be arranged in the space between the plug-in component 2 and the switch 3 of the existing socket, only a corresponding fixing structure needs to be provided on the socket housing 1 to fix the overload protector 4, without changing other structures on the socket housing 1 and the layout of other devices on the socket housing 1.

[0088] In other examples, such as Figure 25 As shown, along the length direction X of the socket, the switch 3 is arranged between the overload protector 4 and the plug-in component 2. Then the fourth conductive sheet 44 is connected to the power cord 5, and the first conductive sheet 31 is electrically connected to the plug-in component 2. Of course, the switch 3 and the overload protector 4 can also be arranged inside the socket housing 1 in other ways, and the embodiments of the present disclosure do not make specific limitations on this.

[0089] In some examples, such as Figure 1 、 Figure 23 and Figures 26 - 27 As shown, the switch button 33 of the switch 3 and the reset button 450 of the overload protector 4 are exposed on the socket surface of the socket housing 1. In this way, on the one hand, the position where the reset button 450 is located is relatively prominent, which is beneficial to reminding the user to press the reset button 450. On the other hand, the reset button 450 is located on the jack surface, and the jack surface will certainly not be blocked (otherwise the plug cannot be inserted). Therefore, the possibility that the reset button 450 cannot pop up after the socket is overloaded is reduced.

[0090] In some examples, such asFigure 1 , Figure 23 and Figures 26 - 27 As shown in Figure 1 , Figure 23 and Figures 26 - 27 , the switch button 33 and the reset button 450 are located on the central axis I of the socket. Among them, the central axis I is the central axis extending along the length direction X of the socket. In this way, the socket is made more beautiful.

[0091] In some examples, as Figure 1 and Figure 23 shown, along the length direction X of the socket, the reset button 450 is arranged between the switch button 33 and the plug-in component 2. In other examples, as Figures 26 - 27 shown, along the length direction X of the socket, the switch button 33 is arranged between the reset button 450 and the plug-in component 2.

[0092] The embodiments of the present disclosure do not limit on which side of the overload protector 4 the third conductive sheet 43 is provided. Among them, since the overload protector 4 and the switch 3 are arranged along the length direction X, the overload protector 4 should not have too large a size in the length direction X. Otherwise, it may be necessary to increase the size of the socket housing 1 in the length direction X. Therefore, in some examples, as Figure 3 shown, the exposed part of the third conductive sheet 43 is located on one side of the overload protector 4 in the width direction Y of the socket.

[0093] In some examples, as Figure 4 shown, the overload protector 4 includes an overload protector housing 41. A part of the third conductive sheet 43 is located inside the overload protector housing 41, and the other part passes through one side of the overload protector housing 41 in the width direction Y of the socket and contacts and is electrically connected to the second conductive sheet 32.

[0094] Exemplarily, as Figure 6 shown, the overload protector housing 41 includes: a bottom plate 411, a top plate 412, two first side plates 413 and two second side plates 414. The two first side plates 413 are arranged opposite to each other along the length direction X of the socket. The two second side plates 414 are arranged opposite to each other along the width direction Y of the socket. The third conductive sheet 43 passes through any one of the two second side plates 414 and contacts and is electrically connected to the second conductive sheet 32.

[0095] In some examples, as Figure 3 shown, the second-pole cable 52 bypasses from the outside of one of the two second side plates 414 and is connected to the second-pole socket 22 of the plug-in component 2. Then the third conductive sheet 43 passes through the other second side plate 414 of the two second side plates 414. In this way, the third conductive sheet 43 and the second-pole cable 52 are arranged on both sides of the overload protector 4 respectively. Thus, the interference between the second-pole cable 52 and the third conductive sheet 43 is avoided, and the reliability of the socket is improved.

[0096] In some examples, as Figure 3 shown, the power cord 5 further includes a third-pole cable 53. The second-pole cable 52 and the third-pole cable 53 bypass from the outside of the same second side plate 414 and are respectively connected to the second-pole socket 22 and the third-pole socket 23 of the plug-in assembly 2. In this way, interference between the third-pole cable 53 and the third conductive sheet 43 can be avoided, improving the reliability of the socket. Among them, the above-mentioned third pole is the E pole.

[0097] In some examples, as Figure 6 shown, the switch 3 includes: a switch housing 30. A part of the second conductive sheet 32 is located inside the switch housing 30, and the other part passes through the switch housing 30 and faces the side plate of the overload protector 4. The other part of the second conductive sheet 32 includes a connected extension section 321 and a first connection section 322. The extension section 321 is arranged between the switch 3 and the overload protector 4. The extension section 321 extends along the width direction Y of the socket and is vertically arranged along the height direction Z. The first connection section 322 is bent relative to the extension section 321 toward the second side plate 414 through which the third conductive sheet 43 passes, and contacts and connects with the third conductive sheet 43.

[0098] The technical solution provided by the embodiments of the present disclosure, by arranging the extension section 321 to extend along the width direction Y of the socket and be vertically arranged along the height direction Z, is beneficial to reducing the distance between the overload protector 4 and the switch 3 and reducing the size occupied by the overload protector 3 and the switch 3 in the length direction X.

[0099] In some examples, as Figure 6 shown, the first connection section 322 is located on one side of the second side plate 414 along the width direction Y.

[0100] In some examples, as Figure 6 shown, the fourth conductive sheet 44 passes through the first side plate 413 of the two first side plates 413 that is opposite to the switch 3. The first conductive sheet 31 passes through the plate body of the switch housing 30 of the switch 3 that is opposite to the overload protector 4. In this way, it is convenient for the first conductive sheet 31 to connect the power cord 5 and the fourth conductive sheet 44 to connect the plug-in assembly 2. Or, the first conductive sheet 31 connects the plug-in assembly 2 and the fourth conductive sheet 44 connects the power cord 5.

[0101] The embodiments of the present disclosure do not limit the connection method between the second conductive sheet 32 of the switch 3 and the third conductive sheet 43 of the overload protector 4. In some examples, the second conductive sheet 32 includes a first connection section 322, and the third conductive sheet 43 includes a second connection section 431. The first connection section 322 and the second connection section 431 are welded.

[0102] In other examples, as Figure 4 and Figure 6As shown, one of the first connection section 322 and the second connection section 431 is a plug sleeve, and the other is a plug sheet, and the plug sleeve clamps the plug sheet. In this way, the first connection section 322 and the second connection section 431 are detachably connected, which facilitates the separation of the switch 3 and the overload protector 4 (so that the plug sheet can be pulled out of the plug sleeve) after the switch 3 or the overload protector 4 is damaged, and the switch 3 or the overload protector 4 can be replaced independently.

[0103] It is understandable that if the first connection section 322 and the second connection section 431 are welded, the operation of removing the welding of the first connection section 322 and the second connection section 431 is relatively cumbersome. Of course, the technical solution provided in the embodiment of the present disclosure does not exclude the technical solution of welding the first connection section 322 and the second connection section 431.

[0104] In some examples, such as Figure 4 As shown, the first connecting section 322 is a plug-in sheet, and the second connecting section 431 is a plug-in sleeve. In this way, the complexity of the second conductive sheet 32 ​​can be reduced.

[0105] The embodiment of the present disclosure does not limit the direction of the opening of the plug sleeve. In some examples, such as Figure 6 As shown, the opening of the plug sleeve faces the bottom of the socket housing 1. Figure 7 As shown, in the process of assembling the switch 3 and the overload protector 4, the overload protector 4 is first installed on the socket cover 12. Then, according to Figure 7 In the direction of the arrow, the switch 3 is installed on the socket cover 12. During the installation process, the plug piece gradually extends into the socket sleeve.

[0106] In addition, in order to improve the clamping force of the plug sleeve to clamp the plug sheet, so as to improve the reliability of the electrical connection between the plug sleeve and the plug sheet, in some examples, such as Figure 8 As shown, the insert sheet includes two layers of metal sheets 320. That is, the insert sheet is formed by folding two layers of metal sheets 320. In this way, the thickness of the insert sheet is relatively large, which is convenient for improving the clamping force of the insert sleeve to clamp the insert sheet.

[0107] In order to improve the smoothness of the insertion of the plug into the socket, in some examples, such as Figure 7 and Figure 8 As shown, two layers of metal sheets 320 are folded to form an insert, and the bent portion 3201 of the two layers of metal sheets 320 is close to the socket cover 12. The bent portion 3201 has rounded corners. In this way, when the switch 3 is installed on the socket cover 12, the bent portion 3201 first abuts against the socket sleeve and opens the socket sleeve. Since the bent portion 3201 has rounded corners, the bent portion 3201 can open the socket sleeve more smoothly.

[0108] In addition, before the plug piece opens the socket, the plug piece will drive the socket to move toward the socket cover 12. In order to avoid the socket from being greatly deformed under the drive of the plug piece, in some examples, such as Figure 7 As shown, the socket cover 12 includes a support column 121, and the support column 121 abuts against the socket. In this way, the support column 121 abuts against the socket to prevent the socket from being greatly deformed under the drive of the plug. Figure 7 Only a portion of the socket cover 12 is shown.

[0109] Next, the positioning method of the switch 3 and the overload protector 4 in the socket housing 1 is exemplarily described.

[0110] Figure 9 The switch 3 and the overload protector 4 are shown in the positioning mode of the socket cover 12. In some examples, such as Figure 9 As shown, the socket cover 12 includes a plurality of first positioning columns 122 and a plurality of second positioning columns 123. The plurality of first positioning columns 122 abut against the switch 3, and the plurality of second positioning columns 123 abut against the overload protector 4.

[0111] in, Figure 9 Only a portion of the socket cover 12 is shown to facilitate observation of the first positioning column 122 and the second positioning column 123. The socket cover 12 includes a switch button hole 124 for the switch button 33 to pass through, and a reset button hole 125 for the reset button 450 to pass through.

[0112] In some examples, such as Figure 9 As shown, the switch 3 includes a plurality of first positioning pins 301, and the overload protector 4 includes a plurality of second positioning pins 4121. The plurality of first positioning columns 122 and the plurality of second positioning columns 123 are both cylindrical, and the plurality of first positioning pins 301 extend into the plurality of first positioning columns 122, respectively, and the plurality of second positioning pins 4121 extend into the plurality of second positioning columns 123, respectively. In this way, under the action of the plurality of first positioning columns 122 and the plurality of first positioning pins 301, the switch 3 is positioned on the socket cover 12. Under the action of the plurality of second positioning columns 123 and the plurality of second positioning pins 4121, the overload protector 4 is positioned on the socket cover 12.

[0113] Of course, in other examples, the switch 3 may include multiple first grooves, and the overload protector 4 may include multiple second grooves. The multiple first positioning columns 122 extend into the multiple first grooves of the switch 3 to position the switch 3 on the socket cover 12. The multiple second positioning columns 123 extend into the multiple second grooves of the overload protector 4 to position the overload protector 4 on the socket cover 12.

[0114] The following is an exemplary description of the principle of overload protection achieved by the overload protector 4.

[0115] Figure 10 Shows an exploded view of the overload protector 4. Figure 11 and Figure 12 Shows a schematic diagram of the overload protector 4 changing from the normal state to the overload state.

[0116] As Figure 10 shown, the overload protector 4 includes: an overload protector housing 41 (including two parts: an overload protector bottom case 41a and an overload protector upper cover 41b), an overload protection member 42, a third conductive sheet 43, and a fourth conductive sheet 44. The overload protection member 42 is located inside the overload protector housing 41, and both ends of the overload protection member 42 are respectively connected to one end of the third conductive sheet 43 and one end of the fourth conductive sheet 44. Among them, the overload protection member 42 is connected to the target conductive sheet among the third conductive sheet 43 and the fourth conductive sheet 44 through a contact. That is, the target conductive sheet can be the third conductive sheet 43 or the fourth conductive sheet 44. Exemplarily, the target conductive sheet is the third conductive sheet 43, that is, the third conductive sheet 43 is connected to the overload protection member 42 through a contact. For example, the third conductive sheet 43 has a static contact, and the overload protection member 42 has a moving contact, and the static contact abuts against the moving contact.

[0117] Among them, the overload protection member 42 can be a bimetallic strip. The bimetallic strip is composed of two metals with different coefficients of thermal expansion. When current passes through, the bimetallic strip will bend and deform due to the heat generated by the current. In this way, when the overload protector 4 is overloaded, the bimetallic strip will deform due to the increase in temperature and separate from the third conductive sheet 43 or the fourth conductive sheet 44 (for example, separate from the third conductive sheet 43), thereby cutting off the power supply and reducing the possibility of danger.

[0118] In some examples, as Figure 11 and Figure 12 shown, the overload protection member 42 extends along the width direction Y of the socket and is vertically arranged in the height direction Z of the socket. In this way, the size of the overload protection member 42 in the length direction X of the socket is small, and further the size of the overload protector 4 in the length direction X is small, which is beneficial to the arrangement of the overload protector 4 and the switch 3 along the length direction X of the socket. In addition, by setting the overload protection member 42 to extend along the width direction Y of the socket instead of the height direction Z, it is beneficial for the third conductive sheet 43 and the fourth conductive sheet 44 to be at an appropriate height. Of course, the technical solution in which the overload protection member 42 provided in the embodiments of the present disclosure extends along the height direction Z of the socket is not excluded.

[0119] Next, taking the overload protection component 42 as a bimetal sheet as an example, an exemplary description of the overload protection component 42 will be given. Among them, because the thickness of the bimetal sheet is relatively thin (such as less than 0.2 mm), the stiffness of the bimetal sheet is relatively small, and it is easy for the bimetal sheet to separate from the target conductive sheet with a slight change in temperature.

[0120] For this reason, as Figure 12 shown, the bimetal sheet includes a first convex hull 421, and the first convex hull 421 is formed by stamping to enhance the stiffness of the position of the first convex hull 421 on the bimetal sheet. The convex surface of the first convex hull 421 is used to abut against the target conductive sheet (such as the third conductive sheet 43). For example, the convex surface of the first convex hull 421 includes a moving contact. In this way, under the action of the first convex hull 421, the stiffness of the bimetal sheet is relatively large, so that the bimetal sheet will only deform instantaneously when the temperature is higher than the preset temperature threshold, avoiding abnormal separation of the bimetal sheet from the target conductive sheet.

[0121] In addition, as Figure 12 shown, the bimetal sheet further includes a second convex hull 422, and the second convex hull 422 is formed by stamping to enhance the stiffness of the position of the second convex hull 422 on the bimetal sheet. The convex surface of the second convex hull 422 is used to connect (such as welding) with the non-target conductive sheet (such as the fourth conductive sheet 44), so as to make the connection between the bimetal sheet and the fourth conductive sheet 44 more firm.

[0122] As Figure 12 shown, the bimetal sheet further includes a third convex hull 423, and the third convex hull 423 is located between the first convex hull 421 and the second convex hull 422. Among them, the third convex hull 423 is in the shape of a pot-like protrusion, so the bimetal sheet is also called a snap dome switch. In some examples, as Figure 12 shown, the protruding direction of the third convex hull 423 is the same as the springing direction (or separation direction) of the bimetal sheet.

[0123] In order to enable the user to continue using the socket after the overload condition is eliminated, as Figure 10 shown, the overload protector 4 further includes a reset component 45. The reset component 45 is configured to keep the overload protection component 42 disconnected from the target conductive sheet when the overload protection component 42 is disconnected from the target conductive sheet. When the reset component 45 is triggered by the user, the overload protection component 42 is reconnected to the target conductive sheet. Among them, a part of the reset component 45 is exposed on the socket surface, and the exposed part forms a reset button 450.

[0124] Next, an exemplary description of the implementation manner of the reset component 45 will be given. Figure 13 And Figure 14 show a schematic diagram of the overload protector 4 changing from the normal state to the overload state. In some examples, as Figure 13 And Figure 14As shown, the reset assembly 45 includes a reset rod 451 and an elastic member 452. A part of the reset rod 451 is located inside the overload protector housing 41, and the other part is located outside the overload protector housing 41 and is exposed on the jack surface of the socket. Among them, the exposed part forms a reset button 450. The elastic member 452 is located inside the overload protector housing 41 and abuts against the reset rod 451. Among them, the elastic member 452 is in a compressed state.

[0125] In some examples, the reset rod 451 is slidably connected to the overload protector housing 41, and the sliding direction is along the height direction Z of the socket.

[0126] As Figure 13 and Figure 14 shown, when the overload protector 4 changes from the normal state to the overload state, the overload protection member 42 (bimetal) deforms due to the temperature rise and separates from the target conductive sheet (such as the third conductive sheet 43) to cut off the power supply. When the overload protection member 42 separates from the third conductive sheet 43, under the drive of the elastic member 452, the reset rod 451 is inserted between the overload protection member 42 and the third conductive sheet 43. Thus, it is prevented that the overload protection member 42 rebounds and comes into contact with the third conductive sheet 43 again due to the temperature drop before the overload condition is eliminated. That is, the reset assembly 45 is used to prevent the overload protection member 42 and the third conductive sheet 43 from automatically coming into contact again after the overload protection member 42 separates from the third conductive sheet 43.

[0127] According to Figure 13 and Figure 14 the arrow's reverse direction in Figure 13 and Figure 14 view, when the overload condition is eliminated, the user presses the reset rod 451, the reset rod 451 compresses the elastic member 452 and withdraws from between the overload protection member 42 and the third conductive sheet 43, then the overload protection member 42 loses the block of the reset rod 451. Since the temperature of the overload protection member 42 has dropped, the overload protection member 42 automatically rebounds and comes into contact with the third conductive sheet 43 again, the circuit between the third conductive sheet 43 and the fourth conductive sheet 44 is conducted, and the overload protector 4 returns from the overload state to the normal state. The user can use the socket normally.

[0128] Next, an exemplary description of the form of the reset rod 451 will be given.

[0129] In some examples, such as Figure 13As shown, the reset rod 451 includes a rod body 4511 and a partition rib 4512. A part of the rod body 4511 is located inside the overload protector housing 41 and abuts against the elastic member 452. Another part is located outside the overload protector housing 41 and is exposed on the jack surface of the socket housing 1. The partition rib 4512 is connected to one side of the rod body 4511, and the partition rib 4512 is used to be inserted between the overload protection member 42 and the contact of the target conductive sheet.

[0130] In some examples, as Figure 12 shown, if the convex surfaces of the first convex hull 421 and the second convex hull 422 face the first side, then the reset rod 451 is located on the first side of the overload protection member 42 to improve space utilization.

[0131] Next, an exemplary description of the assembly process of the overload protector 4 will be given. And, in combination with the assembly process of the overload protector 4, an exemplary description of the corresponding assembly structure will be given.

[0132] The first step, as Figure 15 shown, the connected overload protection member 42 and the fourth conductive sheet 44 are assembled together into the overload protector bottom shell 41a.

[0133] Among them, in some examples, as Figure 15 shown, a first opening 4131 is provided on the shell wall of the overload protector bottom shell 41a. The first opening 4131 penetrates the shell wall in the thickness direction and is open on the side facing the overload protector upper cover 41b. When performing the first-step assembly, the fourth conductive sheet 44 is aligned with the first opening 4131. When the fourth conductive sheet 44 moves to contact the bottom of the first opening 4131, the first-step assembly is completed.

[0134] In some examples, as Figure 15 shown, the first opening 4131 is trumpet-shaped on the side facing the overload protector upper cover 41b to improve the smoothness of inserting the fourth conductive sheet 44 into the first opening 4131.

[0135] In addition, as Figure 15 shown, the inside of the overload protector bottom shell 41a includes a first limiting groove 415. The first limiting groove 415 is used to receive the connecting part of the overload protection member 42 and the fourth conductive sheet 44 and limit the connecting part to prevent the overload protection member 42 and the fourth conductive sheet 44 from separating.

[0136] The second step, as Figure 16 and Figure 17 shown, the reset rod 451 is loaded into the overload protector bottom shell 41a.

[0137] In some examples, as Figure 16 and Figure 17As shown, the reset rod 451 includes an elastic member abutting portion 4510, a first limiting rib 4513, a second limiting rib 4514, and a separating rib 4512. The first limiting rib 4513 and the second limiting rib 4514 are fixed to the side wall of the elastic member abutting portion 4510, and the separating rib 4512 is connected to the second limiting rib 4514.

[0138] The interior of the overload protector bottom shell 41a includes a channel 416 for accommodating the elastic member abutting portion 4510 and the elastic member 452. The channel wall of the channel 416 includes a second opening 4161 and a third opening 4162. The second opening 4161 is for receiving the first limiting rib 4513, and the third opening 4162 is for receiving the second limiting rib 4514. After the first limiting rib 4513 and the second limiting rib 4514 respectively extend into the second opening 4161 and the third opening 4162, the reset rod 451 is circumferentially limited.

[0139] The third step, as Figure 18 shown, install the third conductive sheet 43 into the overload protector bottom shell 41a.

[0140] In some examples, as Figure 18 shown, the overload protector bottom shell 41a includes a fourth opening 417 that penetrates the shell wall of the overload protector bottom shell 41a in the thickness direction and is open on the side facing the overload protector upper cover 41b. When assembling the third conductive sheet 43, align the third conductive sheet 43 with the fourth opening 417. When the third conductive sheet 43 moves to contact the bottom of the fourth opening 417, the assembly is completed. At the same time, the third conductive sheet 43 abuts against the overload protection member 42.

[0141] In some examples, as Figure 18 shown, the fourth opening 417 is flared on the side facing the overload protector upper cover 41b to improve the smoothness of inserting the third conductive sheet 43 into the fourth opening 417.

[0142] The fourth step, as Figure 19 shown, snap the overload protector upper cover 41b onto the overload protector bottom shell 41a. In some examples, as Figure 19 and Figure 20 shown, the overload protector bottom shell 41a includes a plurality of positioning holes 418. As Figure 19 and Figure 21 shown, the overload protector upper cover 41b includes a plurality of third positioning pins 419, and the plurality of third positioning pins 419 respectively extend into the plurality of positioning holes 418.

[0143] In some examples, as Figure 20 and Figure 21As shown, the cross-section of the positioning hole 418 is square. The cross-section of the third positioning pin 419 is circular. The third positioning pin 419 and the positioning hole 418 can be in interference fit.

[0144] In some examples, as Figure 20 and Figure 21 shown, there are four positioning holes 418, and the four positioning holes 418 are respectively located at the four corner positions of the bottom case 41a of the overload protector. There are four third positioning pins 419, and the four third positioning pins 419 are respectively located at the four corner positions of the upper cover 41b of the overload protector.

[0145] In some examples, as Figure 21 shown, the upper cover 41b of the overload protector includes a reset rod through hole 4110, and the reset rod 451 passes through the reset rod through hole 4110.

[0146] In some examples, as Figure 21 shown, the upper cover 41b of the overload protector includes a first protrusion 4111, and the first protrusion 4111 extends into the first opening 4131. In some examples, as Figure 21 shown, the upper cover 41b of the overload protector includes a second protrusion 4112, and the second protrusion 4112 extends into the fourth opening 417. In some examples, as Figure 21 shown, the first protrusion 4111 is strip-shaped. The second protrusion 4112 is conical, and along the direction away from the upper cover 41b of the overload protector, the width of the second protrusion 4112 gradually decreases.

[0147] In some examples, as Figure 19 and Figure 21 shown, the upper cover 41b of the overload protector further includes a baffle 4113. The baffle 4113 is located outside the bottom case 41a of the overload protector, and the baffle 4113 blocks a part of the fourth conductive sheet 44. Thus, as Figure 3 shown, the baffle 4113 separates the second pole socket 22 from the fourth conductive sheet 44, which can avoid abnormal conduction between the two and prevent danger caused by too small electrical clearance.

[0148] The fifth step, as Figure 22 shown, assemble the elastic member 452 into the channel 416, and one end abuts against the reset rod 51. Use the plug 46 to block the channel 416, then the other end of the elastic member 452 abuts against the plug 46, thereby realizing the limit of the elastic member 452.

[0149] In some examples, as Figure 22 shown, the bottom case 41a of the overload protector includes a receiving groove 4114, and the bottom of the receiving groove 4114 communicates with the channel 416. The plug 46 is in interference fit with the receiving groove 4114.

[0150] In some examples, asFigure 22 As shown, the cross-section of the receiving groove 4114 is square, and the cross-section of the plugging block 46 is circular. In some examples, such as Figure 22 As shown, in order to facilitate the deformation of the plugging block 46, the plugging block 46 is provided with a through hole 461 axially penetrating therethrough. Alternatively, it can also be said that the plugging block 46 is in a cylindrical shape.

[0151] In addition to Figure 1 and Figure 2 the socket shown including a single row of plug-in components 2 (or jacks), the socket provided by the embodiments of the present disclosure can also be Figure 23 , Figure 24 and Figure 27 the socket shown including two rows of plug-in components 2 (or jacks).

[0152] In addition, as Figure 1 shown, the socket further includes an indicator light 6, and the indicator light 6 and the switch 3 (or the overload protector 4) are arranged at both ends of the socket along the length direction X.

[0153] Although the present invention has been described in detail above with general descriptions and specific embodiments, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope claimed by the present invention.
