Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and in particular to a socket. Background Art

[0002] As electrical appliances continue to increase, users may experience socket overloads when using sockets. To improve socket safety, an overload protector is added to the socket, which 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, thereby avoiding danger.

[0003] In the related art, some sockets are equipped with switches, and users can control the power on and off of the sockets by pressing the switches. However, in order to add an overload protector to a socket with a switch, the switch and the overload protector need to be connected together through a cable, which makes the cable routing inside the socket complicated. In addition, the space required for the overload protector and the newly added cables is large, which requires the socket housing of the socket to be improved, increasing the cost of the socket.

The first connecting section is bent relative to the extension section toward the second side plate through which the third conductive sheet passes, and is in contact with and electrically connected to the third conductive sheet.

[0014] In a possible implementation, the fourth conductive sheet passes through the first side sheet of the two first side sheets facing away from the switch. The first conductive sheet passes through the switch housing of the switch facing away from the plate body of the overload protector.

[0015] In a possible implementation, the second conductive sheet includes a first connecting section, and the third conductive sheet includes a second connecting section.

[0065] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0066] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0067] In recent years, with the continuous improvement of living standards, users' demands for electrical equipment have also been continuously enriched. When users use sockets, sockets are often overloaded. When the socket is overloaded, it may cause a fire in serious cases, which is very dangerous. Therefore, in order 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 to avoid danger.

[0068] In the related art, some sockets are equipped with switches, and users can control the power on and off of the socket by pressing the switch button. In order to add an overload protector to a socket with a switch, one solution is to connect the switch and the overload protector together through a cable, which makes the cable routing inside the socket complicated. In addition, the space required for the overload protector and the newly added cables is large, which requires improvements to the socket housing of the socket, increasing the cost of the socket. Another solution is to integrate the switch and the overload protector together, however, this is not conducive to independent replacement of the switch and the overload protector. When one of the two is damaged, both need to be replaced together.

[0069] In addition, the reset button of the overload protector in the related art is often exposed on the side of the socket. On the one hand, the reset button is not conspicuous, 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 make the reset button unable to pop out due to the obstruction of the wall after the socket is overloaded, which is very dangerous.

[0070] In view of the above technical problems, an embodiment of the present disclosure provides a socket. Figure 1 An outline view of the socket is shown. Figure 2 and Figure 3 A schematic diagram showing the internal structure of the socket is shown. Figure 1-Figure 3 As shown, the socket comprises a socket housing 1, a plug assembly 2, a switch 3 and an overload protector 4. The plug assembly 2, the switch 3 and the overload protector 4 are fixed to the socket housing 1. Figure 4-Figure 6 FIG. 4 shows a schematic diagram of a switch 3 and an overload protector 4. Figure 3-Figure 6 As 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 and 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 line, and the other is electrically connected to the plug assembly 2.

[0071] Among them, Figure 1As shown, the socket housing 1 includes a socket bottom shell 11 and a socket upper cover 12. The socket upper cover 12 includes a socket surface. The plug assembly 2 is used to dock with the plug, and the plug assembly 2 includes a protective door assembly and a corresponding socket part. Each plug assembly 2 is used to dock with at least one plug, which 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 socket surface of the socket housing 1. The user can control the on and 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 method 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.

[0072] The technical solutions provided by the embodiments of the present disclosure are as follows: Figure 3 As 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 assembly 2 of the socket and the power cord 5 is disconnected. Thus, the possibility of the socket being dangerous is reduced.

[0073] Furthermore, by setting the third conductive sheet 43 of the overload protector 4 to be in direct contact and electrically connected with the second conductive sheet 32 ​​of the switch 3, rather than being connected through a cable, the complexity of the cable routing inside the socket is reduced. Moreover, this also makes the distance between the overload protector 4 and the switch 3 closer, and the two are closer, which reduces the space required for the overload protector 4 and the switch 3, so that there is no need to increase the socket housing 1, and the newly added overload protector 4 can be accommodated in the socket housing 1, thereby reducing the cost of the socket. In addition, by setting the overload protector 4 and the switch 3 as two independent components, rather than integrating them together, when one of the overload protector 4 and the switch 3 is damaged, only the damaged component can be replaced without replacing both together, which also reduces the cost of the socket.

[0074] In some examples, such as Figure 3 As shown, the power cord 5 includes a first pole cable 51 and a second pole cable 52, and the plug assembly 2 includes a first pole socket 21 and a second pole socket 22. The first pole may be an L pole, and the second pole may be an N pole. One of the first conductive sheet 31 and the fourth conductive sheet 44 may be connected to the first pole cable 51, and the other may be electrically connected to the first pole socket 21.

[0075] The plug-in assembly 2 may include a first pole copper bar on which a first pole socket 21 is disposed. The first conductive sheet 31 or the fourth conductive sheet 44 may be electrically connected to the first pole socket 21 by directly contacting the first pole copper bar.

[0076] The embodiment of the present disclosure does 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 2and Figure 3 As shown, along the length direction X of the socket, the overload protector 4 is arranged between the plug assembly 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 assembly 2. In this way, the space between the plug assembly 2 and the switch 3 is fully utilized, and the space utilization rate inside the socket housing 1 is improved. In addition, there is no need to improve other parts of the socket housing 1 or to make too much improvement, which reduces the cost. It should be noted that the overload protector 4 can be arranged in the space between the plug assembly 2 and the switch 3 of the existing socket, and it is only necessary to set a corresponding fixed structure 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 in the socket housing 1.

[0077] In other examples, such as Fig.25 As shown, along the length direction X of the socket, the switch 3 is arranged between the overload protector 4 and the plug assembly 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 assembly 2. Of course, the switch 3 and the overload protector 4 can also be arranged inside the socket housing 1 in other ways, which is not specifically limited in the embodiment of the present disclosure.

[0078] In some examples, such as Figure 1 , Fig.23 and Figure 26-Figure 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 of the reset button 450 is more eye-catching, which is helpful to remind the user to press the reset button 450. On the other hand, the reset button 450 is located on the socket surface, and the socket surface will definitely not be blocked (otherwise the plug cannot be inserted), so the possibility of the reset button 450 not being able to pop out after the socket is overloaded is reduced.

[0079] In some examples, such as Figure 1 , Fig.23 and Figure 26-Figure 27 As shown, the switch button 33 and the reset button 450 are located on the central axis I of the socket. The central axis I is the central axis extending along the length direction X of the socket. In this way, the socket is more beautiful.

[0080] In some examples, such as Figure 1 and Fig.23 As shown, along the length direction X of the socket, the reset button 450 is arranged between the switch button 33 and the plug assembly 2. In other examples, such as Figure 26-Figure 27 As shown, along the length direction X of the socket, the switch button 33 is arranged between the reset button 450 and the plug assembly 2.

[0081] The embodiment of the present disclosure does not limit which side the third conductive sheet 43 is disposed on for the overload protector 4. 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, the size of the socket housing 1 in the length direction X may need to be increased. Therefore, in some examples, such as Figure 3 As shown, the exposed portion of the third conductive sheet 43 is disposed on one side of the overload protector 4 in the width direction Y of the socket.

[0082] In some examples, such as Figure 4 As shown, the overload protector 4 includes an overload protector housing 41, a portion of the third conductive sheet 43 is located inside the overload protector housing 41, and another portion passes through the overload protector housing 41 along one side of the width direction Y of the socket and contacts and is electrically connected to the second conductive sheet 32.

[0083] For example, Figure 6 As 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.

[0084] In some examples, such as Figure 3 As shown, the second pole cable 52 is passed around the outside of one of the two second side plates 414 and connected to the second pole socket 22 of the plug assembly 2. The third conductive sheet 43 passes through the other 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.

[0085] In some examples, such as Figure 3 As shown, the power cord 5 also includes a third pole cable 53, and the second pole cable 52 and the third pole cable 53 are bypassed 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 assembly 2. In this way, the third pole cable 53 can be prevented from interfering with the third conductive sheet 43, thereby improving the reliability of the socket. The third pole is the E pole.

[0086] In some examples, such as Figure 6As shown, the switch 3 includes a switch housing 30, a portion of the second conductive sheet 32 ​​is located inside the switch housing 30, and the other portion passes through the switch housing 30 toward the side plate of the overload protector 4. The other portion of the second conductive sheet 32 ​​includes a connected extension section 321 and a first connecting 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 connecting 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.

[0087] The technical solution provided by the embodiment of the present disclosure is beneficial to reduce the distance between the overload protector 4 and the switch 3, and reduce the size occupied by the overload protector 3 and the switch 3 in the length direction X by setting the extension section 321 to extend along the width direction Y of the socket and to be vertically set along the height direction Z.

[0088] In some examples, such as Figure 6 As shown, the first connecting section 322 is located at one side of the second side plate 414 along the width direction Y.

[0089] In some examples, such as Figure 6 As shown, the fourth conductive sheet 44 passes through the first side plate 413 of the two first side plates 413 facing away from the switch 3. The first conductive sheet 31 passes through the switch housing 30 of the switch 3 facing away from the plate body of the overload protector 4. In this way, it is convenient for the first conductive sheet 31 to connect to the power line 5 and the fourth conductive sheet 44 to connect to the plug assembly 2. Alternatively, the first conductive sheet 31 is connected to the plug assembly 2 and the fourth conductive sheet 44 is connected to the power line 5.

[0090] The embodiment of the present disclosure does not limit the connection method of 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 segment 322, and the third conductive sheet 43 includes a second connection segment 431. The first connection segment 322 and the second connection segment 431 are welded.

[0091] In other examples, such as Figure 4 and Figure 6 As 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. 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] Next, the positioning method of the switch 3 and the overload protector 4 in the socket housing 1 is exemplarily described.

[0099] Fig. 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 Fig. 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.

[0100] in, Fig. 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.

[0101] In some examples, such as Fig. 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.

[0102] 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.

[0103] The following is an exemplary description of the principle of overload protection achieved by the overload protector 4.

[0104] Fig.10 An exploded view of the overload protector 4 is shown. Fig.11 and Fig.12 FIG. 4 is a schematic diagram showing the overload protector 4 changing from a normal state to an overload state. Fig.10As shown, the overload protector 4 also includes an overload protector housing 41 (including an overload protector bottom shell 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 the two 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 of 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, the overload protection member 42 has a moving contact, and the static contact abuts the moving contact.

[0105] The overload protection member 42 may be a bimetallic strip. The bimetallic strip is composed of two metals with different thermal expansion coefficients. 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.

[0106] In some examples, such as Fig.11 and Fig.12 As shown, the overload protection member 42 extends along the width direction Y of the socket and is arranged vertically 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, which makes the size of the overload protector 4 in the length direction X small, which is conducive 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 extending along the height direction Z, it is conducive to the third conductive sheet 43 and the fourth conductive sheet 44 being at a suitable height. Of course, the overload protection member 42 provided in the embodiment of the present disclosure does not exclude the technical solution of extending along the height direction Z of the socket.

[0107] The following is an example of the overload protection member 42 being a bimetallic strip, where the bimetallic strip is relatively thin (e.g., less than 0.2 mm), resulting in a relatively small stiffness of the bimetallic strip, which can easily cause the bimetallic strip to separate from the target conductive strip when the temperature changes slightly.

[0108] For this reason, Fig.12As shown, the bimetallic strip includes a first convex bump 421, and the first convex bump 421 is stamped to enhance the rigidity of the position of the first convex bump 421 on the bimetallic strip. The convex surface of the first convex bump 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 bump 421 includes a moving contact. In this way, under the action of the first convex bump 421, the rigidity of the bimetallic strip is relatively large, so that the bimetallic strip will only deform instantly when the temperature is higher than the preset temperature threshold, thereby avoiding abnormal separation of the bimetallic strip from the target conductive sheet.

[0109] In addition, if Fig.12 As shown, the bimetallic strip further includes a second convex bump 422, which is formed by stamping to enhance the rigidity of the bimetallic strip at the location of the second convex bump 422. The convex surface of the second convex bump 422 is used to connect (such as weld) with a non-target conductive sheet (such as the fourth conductive sheet 44) to make the connection between the bimetallic strip and the fourth conductive sheet 44 more secure.

[0110] like Fig.12 As shown, the bimetallic strip further includes a third convex bump 423, which is located between the first convex bump 421 and the second convex bump 422. The third convex bump 423 is a pot-shaped protrusion, so the bimetallic strip is also called a pot strip. Fig.12 As shown, the protruding direction of the third convex bump 423 is the same as the spring-opening direction (or separation direction) of the bimetallic strip.

[0111] To allow users to continue using the socket after the overload condition is eliminated, Fig.10 As shown, the overload protector 4 further includes a reset component 45. The reset component 45 is configured to keep the overload protector 42 and the target conductive sheet in a disconnected state after the overload protector 42 is disconnected from the target conductive sheet. When the reset component 45 is triggered by the user, the overload protector 42 and the target conductive sheet are reconnected. Part of the reset component 45 is exposed on the socket surface, and the exposed part forms a reset button 450.

[0112] The implementation of the reset component 45 is described below by way of example. Fig.13 and Fig.14 Schematic diagram showing the overload protector 4 changing from a normal state to an overload state. Fig.13 and Fig.14 As shown, the reset assembly 45 includes a reset rod 451 and an elastic member 452. A portion of the reset rod 451 is located inside the overload protector housing 41, and another portion is located outside the overload protector housing 41 and exposed on the socket surface of the socket. The exposed portion forms a reset button 450. The elastic member 452 is located inside the overload protector housing 41 and abuts against the reset rod 451. The elastic member 452 is in a compressed state.

[0113] 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.

[0114] like Fig.13 and Fig.14 As shown, when the overload protector 4 changes from a normal state to an overload state, the overload protection member 42 (bimetallic strip) is deformed due to the increase in temperature and is separated from the target conductive sheet (such as the third conductive sheet 43) to cut off the power supply. After the overload protection member 42 is separated from the third conductive sheet 43, the reset rod 451 is inserted between the overload protection member 42 and the third conductive sheet 43 under the drive of the elastic member 452. Thereby, the overload protection member 42 is prevented from rebounding to contact the third conductive sheet 43 again due to the temperature drop when the overload condition has not been eliminated. That is, the reset component 45 is used to prevent the overload protection member 42 from automatically contacting the third conductive sheet 43 again after the overload protection member 42 is separated from the third conductive sheet 43.

[0115] according to Fig.13 and Fig.14 Observe in the opposite direction of the arrow Fig.13 and Fig.14 When the overload condition is eliminated, the user presses the reset rod 451, and the reset rod 451 compresses the elastic member 452 and is pulled away from between the overload protection member 42 and the third conductive sheet 43, and the overload protection member 42 loses the obstruction of the reset rod 451. Since the temperature of the overload protection member 42 has dropped, the overload protection member 42 automatically rebounds and contacts the third conductive sheet 43 again, and the circuit between the third conductive sheet 43 and the fourth conductive sheet 44 is connected, and the overload protector 4 is restored from the overload state to the normal state. The user can use the socket normally.

[0116] The following is an exemplary description of the form of the reset rod 451. In some examples, such as Fig.13 As shown, the reset rod 451 includes a rod body 4511 and a spacer 4512. A portion of the rod body 4511 is located inside the overload protector housing 41 and abuts against the elastic member 452. The other portion is located outside the overload protector housing 41 and exposed on the plug surface of the socket housing 1. The spacer 4512 is connected to one side of the rod body 4511, and the spacer 4512 is used to be inserted between the overload protector 42 and the contact of the target conductive sheet.

[0117] In some examples, such as Fig.12 As shown, the convex surfaces of the first convex bump 421 and the second convex bump 422 face the first side, and the reset rod 451 is located on the first side of the overload protection member 42 to improve space utilization.

[0118] The following is an exemplary description of the assembly process of the overload protector 4. In addition, in combination with the assembly process of the overload protector 4, an exemplary description of the corresponding assembly structure is given.

[0119] The first step, such as Fig.15 As shown, the overload protection member 42 and the fourth conductive sheet 44 connected together are assembled into the overload protector bottom shell 41a.

[0120] In some examples, such as Fig.15 As shown, a first opening 4131 is provided on the shell wall of the overload protector bottom shell 41a, and the first opening 4131 penetrates the shell wall along the thickness direction and is open on the side facing the overload protector upper cover 41b. When performing the first step of assembly, the fourth conductive sheet 44 is aligned with the first opening 4131, and when the fourth conductive sheet 44 moves to contact with the bottom of the first opening 4131, the first step of assembly is completed.

[0121] In some examples, such as Fig.15 As shown, the first opening 4131 is trumpet-shaped at a side facing the overload protector upper cover 41 b to improve the smoothness of inserting the fourth conductive sheet 44 into the first opening 4131 .

[0122] In addition, if Fig.15 As shown, the interior of the overload protector bottom shell 41a includes a first limiting groove 415, which is used to receive the connecting portion of the overload protection member 42 and the fourth conductive sheet 44 and limit the connecting portion to prevent the overload protection member 42 and the fourth conductive sheet 44 from separating.

[0123] The second step is, Fig.16 and Fig.17 As shown, the reset rod 451 is installed in the overload protector bottom shell 41a.

[0124] In some examples, such as Fig.16 and Fig.17 As shown, the reset rod 451 includes an elastic member abutting portion 4510, a first limiting rib 4513, a second limiting rib 4514 and a spacer 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 spacer rib 4512 is connected to the second limiting rib 4514.

[0125] The interior of the overload protector bottom shell 41a includes a channel 416, and the channel 416 is used to accommodate the elastic member abutment 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 used to receive the first limiting rib 4513, and the third opening 4162 is used to receive the second limiting rib 4514. When the first limiting rib 4513 and the second limiting rib 4514 extend into the second opening 4161 and the third opening 4162 respectively, the reset rod 451 completes the limiting in the circumferential direction.

[0126] The third step is Fig.18 As shown, the third conductive sheet 43 is installed in the bottom shell 41a of the overload protector.

[0127] In some examples, such as Fig.18 As shown, the overload protector bottom shell 41a includes a fourth opening 417, which 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, and when the third conductive sheet 43 moves to contact with 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.

[0128] In some examples, such as Fig.18 As shown, the fourth opening 417 is trumpet-shaped on the side facing the overload protector upper cover 41 b to improve the smoothness of the third conductive sheet 43 being inserted into the fourth opening 417 .

[0129] The fourth step is Fig.19 As shown, the overload protector upper cover 41b is buckled onto the overload protector bottom shell 41a.

[0130] In some examples, such as Fig.19 and Fig. 20 As shown, the overload protector bottom shell 41a includes a plurality of positioning holes 418. Fig.19 and Fig.21 As shown, the overload protector upper cover 41 b includes a plurality of third positioning pins 419 , and the plurality of third positioning pins 419 extend into the plurality of positioning holes 418 respectively.

[0131] In some examples, such as Fig. 20 and Fig.21 As 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 interference fit.

[0132] In some examples, such as Fig. 20 and Fig.21As shown, there are four positioning holes 418, which are respectively located at the four corners of the overload protector bottom shell 41a. There are four third positioning pins 419, which are respectively located at the four corners of the overload protector upper cover 41b.

[0133] In some examples, such as Fig.21 As shown, the overload protector upper cover 41 b includes a reset rod through hole 4110 , and the reset rod 451 passes through the reset rod through hole 4110 .

[0134] In some examples, such as Fig.21 As shown, the overload protector upper cover 41b includes a first protrusion 4111, and the first protrusion 4111 extends into the first opening 4131. In some examples, such as Fig.21 As shown, the overload protector upper cover 41 b includes a second protrusion 4112 , and the second protrusion 4112 extends into the fourth opening 417 .

[0135] In some examples, such as Fig.21 As shown, the first protrusion 4111 is in the shape of a long strip. The second protrusion 4112 is in the shape of a cone, and the width of the second protrusion 4112 gradually decreases in the direction away from the overload protector upper cover 41b.

[0136] In some examples, such as Fig.19 and Fig.21 As shown, the overload protector upper cover 41b further includes a baffle 4113. The baffle 4113 is located outside the overload protector bottom shell 41a, and the baffle 4113 blocks a portion of the fourth conductive sheet 44. Figure 3 As shown, the baffle 4113 separates the second pole sleeve 22 from the fourth conductive sheet 44, which can avoid abnormal conduction between the two and avoid danger caused by too small electrical gap.

[0137] Step 5: Fig. 22 As shown, the elastic member 452 is assembled into the channel 416, and one end thereof abuts against the reset rod 51. The channel 416 is blocked by the sealing plug 46, and the other end of the elastic member 452 abuts against the sealing plug 46, thereby achieving the limiting of the elastic member 452.

[0138] In some examples, such as Fig. 22 As shown, the overload protector bottom shell 41a includes a receiving groove 4114, and the groove bottom of the receiving groove 4114 is connected to the channel 416. The sealing plug 46 is interference-fitted with the receiving groove 4114.

[0139] In some examples, such as Fig. 22 As shown, the cross section of the receiving groove 4114 is square, and the cross section of the sealing plug 46 is circular.

[0140] In some examples, such as Fig. 22As shown, in order to facilitate the deformation of the sealing plug 46, the sealing plug 46 is provided with a through hole 461 that penetrates along the axial direction. Alternatively, it can also be said that the sealing plug 46 is cylindrical.

[0141] Apart from Figure 1 and Figure 2 In addition to the socket including the single-row plug assembly 2 (or socket) shown, the socket provided in the embodiment of the present disclosure can also be Fig.23 , Fig.24 and Fig. 27 The socket shown includes two rows of plug assemblies 2 (or sockets).

[0142] In addition, if Figure 1 As 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.

[0143] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present disclosure shall be included in the protection scope of the present disclosure.
