[0115] 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

[0116] To make the purpose, 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 drawings.

[0117] In recent years, with the continuous improvement of living standards, users' demands for electrical equipment have also become increasingly rich. The demand for users to purchase wireless (cordless) sockets and then wire them by themselves is also increasing. With the continuous enrichment of electrical equipment, when users use sockets, the phenomenon of socket overload often occurs. After the socket is overloaded, in severe cases, it will cause a fire, which is very dangerous.

[0118] In the related art, to improve the safety of the socket, a separate overload protector is added inside the socket, and 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.

[0119] However, the separate overload protector occupies a large space inside the socket and has a high cost. Moreover, for a single-row wireless socket, it is often necessary to lengthen it separately to place the overload protector, resulting in an uncoordinated and unaesthetic product appearance and increasing the cost. Therefore, how to make the socket have an overload protection function without causing a high cost and large volume of the socket is a key technical problem.

[0120] In view of the above technical problems, the embodiments of the present disclosure provide a terminal block with an overload protection function, or it can be understood that the terminal block is integrated with the overload protector, and a socket integrating the terminal block. Among them, the terminal block is used to realize the wiring of the socket. In this way, not only does the socket have an overload protection function, but also the internal space of the socket is saved, so that the size of the socket with an overload protection function is the same as or slightly changed compared with the existing ordinary socket. And compared with the socket with an independent overload protector added, the socket provided by the embodiments of the present disclosure has a lower cost.

[0121] To facilitate understanding of the technical solution provided by the embodiments of the present disclosure, the original function of the terminal block will be introduced first. Figure 1 The external view of the socket is shown. Figure 2 The schematic diagram of the internal structure of the socket after hiding the bottom case is shown. As Figure 1 and Figure 2 shown, the socket includes a socket housing 100, a socket sleeve assembly 200, and a terminal block 300. The socket sleeve assembly 200 and the terminal block 300 are located inside the housing 100. The terminal block 300 is used to connect the cable externally and is electrically connected to the socket sleeve assembly 200 internally. Thus, the terminal block 300 can introduce external current into the socket sleeve assembly 200.

[0122] Figure 3 and Figure 4 The schematic diagram of the terminal block 300 provided by the embodiments of the present disclosure is shown. As Figure 3 and Figure 4As shown, the terminal 300 includes a housing 1 and a plurality of conductive members, which are respectively an L-pole conductive member 2, an N-pole conductive member 3, and an E-pole conductive member 4. The housing 1 includes a plurality of wiring holes, which are respectively an L-pole wiring hole 12, an N-pole wiring hole 13, and an E-pole wiring hole 14. One ends of the L-pole conductive member 2, the N-pole conductive member 3, and the E-pole conductive member 4 respectively extend into the L-pole wiring hole 12, the N-pole wiring hole 13, and the E-pole wiring hole 14, and are respectively used for connecting with an L-pole cable, an N-pole cable, and an E-pole cable. The other ends of the L-pole conductive member 2, the N-pole conductive member 3, and the E-pole conductive member 4 are respectively used for electrically connecting with an L-pole socket assembly 201, an N-pole socket assembly 202, and an E-pole socket assembly 203.

[0123] In addition, as Figure 3 and Figure 4 shown, to achieve the connection between the conductive member and the cable, the terminal 300 further includes an L-pole crimping assembly 7, an N-pole crimping assembly 8, and an E-pole crimping assembly 9. The L-pole crimping assembly 7, the N-pole crimping assembly 8, and the E-pole crimping assembly 9 are respectively used for crimping the L-pole conductive member 2, the N-pole conductive member 3, and the E-pole conductive member 4 to the cables of corresponding polarities. Among them, the implementation manner of the crimping assembly in the embodiments of the present disclosure is not limited. Exemplarily, as Figure 3 shown, by tightening the screws of the L-pole crimping assembly 7, the N-pole crimping assembly 8, and the E-pole crimping assembly 9, the crimping between the conductive member and the cable can be achieved.

[0124] To enable the terminal 300 to have an overload protection function, the embodiments of the present disclosure have improved the L-pole conductive member 2, so that the L-pole conductive member 2 can be disconnected during overload to cut off the power supply. Figure 5 shows a schematic diagram of the terminal 300 after hiding the cover plate 6. Figure 6 shows an exploded view of the terminal 300. Figure 7 shows a schematic diagram of the L-pole conductive member 2.

[0125] As Figure 5 - Figure 7 shown, the L-pole conductive member 2 includes a first conductive sheet 21, a bimetallic sheet 22, and a second conductive sheet 23 that are connected in sequence. Among them, the bimetallic sheet 22 is fixedly connected to one of the first conductive sheet 21 and the second conductive sheet 23, and is connected to the other through a contact. Exemplarily, as Figure 7 shown, the bimetallic sheet 22 has a moving contact 220, and the second conductive sheet 23 has a stationary contact 230. Under the elastic force of the bimetallic sheet 22, the moving contact 220 and the stationary contact 230 are in contact. Among them, the bimetallic sheet 22 is composed of two metals with different coefficients of thermal expansion. When current passes through, the bimetallic sheet 22 will bend and deform due to the heat generated by the current. Of course, the bimetallic sheet 22 can also be replaced with other types of overload protection components, and the overload protection component refers to a metal component that can be disconnected from the conductive sheet during overload.

[0126] In this way, when the terminal 300 is overloaded, the bimetal sheet 22 will deform due to the temperature rise and separate from the first conductive sheet 21 or the second conductive sheet 23 (for example, the moving contact 220 and the static contact 230 separate), thereby cutting off the power supply and reducing the possibility of danger occurrence.

[0127] In order to arrange the first conductive sheet 21, the bimetal sheet 22 and the second conductive sheet 23 on the housing 1 of the terminal 300, as Figure 5 and Figure 6 shown, the housing 1 further includes a receiving cavity 11, and the receiving cavity 11 communicates with the L-pole connection hole 12. One end of the first conductive sheet 21 extends into the L-pole connection hole 12, and the other end extends into the receiving cavity 11 and is connected to one end of the bimetal sheet 22. The other end of the bimetal sheet 22 is connected to one end of the second conductive sheet 23, and the other end of the second conductive sheet 23 extends out of the receiving cavity 11 and is used to connect to the L-pole socket assembly 201.

[0128] It can be understood that since the number of parts of the L-pole conductive part 2 increases, the volume of the housing 1 will increase and the shape of the housing 1 will change. Next, an exemplary description of the shape of the housing 1 will be given.

[0129] In some examples, as Figure 3 - Figure 6 shown, the housing 1 includes an L-pole connection portion 101, an N-pole connection portion 102, an E-pole connection portion 103, and an overload protection portion 104. Among them, the L-pole connection portion 101 includes the L-pole connection hole 12. The N-pole connection portion 102 includes the N-pole connection hole 13. The E-pole connection portion 103 includes the E-pole connection hole 14. The overload protection portion 104 includes the receiving cavity 11.

[0130] In some examples, as Figure 3 - Figure 6 shown, along the first direction X, the L-pole connection portion 101 and the overload protection portion 104 are arranged between the N-pole connection portion 102 and the E-pole connection portion 103. Of course, in some other examples, the L-pole connection portion 101 and the overload protection portion 104 can also be located on one side of the housing 1 instead of the middle position.

[0131] In some examples, as Figure 3 - Figure 6 shown, the L-pole connection portion 101 and the overload protection portion 104 are arranged along the second direction Y, and the overload protection portion 104 is located behind the L-pole connection portion 101. Among them, as Figure 4 shown, the second direction Y is perpendicular to the first direction X. The direction in which the inlets of the L-pole connection hole 12, the N-pole connection hole 13, and the E-pole connection hole 14 face is the front, and the rear is opposite to the front.

[0132] Among them, in some examples, as Figure 2As shown, when the terminal 300 is installed in the socket in the illustrated posture, the first direction X is parallel to the width direction of the socket, and the second direction Y is parallel to the length direction of the socket. Of course, in some other examples, the terminal 300 can also be installed in the socket in other postures, and the embodiments of the present disclosure do not limit this.

[0133] In some examples, as Figure 4 shown, along the second direction Y, the L-pole connection part 101 protrudes forward relative to the N-pole connection part 102 and the E-pole connection part 103. That is, as Figure 4 shown, the L-pole wire pressing assembly 7 protrudes forward relative to the N-pole wire pressing assembly 8 and the E-pole wire pressing assembly 9. Or, the position of the L-pole wire connection hole 12 protrudes forward relative to the position of the N-pole wire connection hole 13 and the position of the E-pole wire connection hole 14. In this way, the influence on the length of the socket housing 100 can be reduced, which is beneficial to applying the terminal 300 provided by the embodiments of the present disclosure without increasing the length of the socket housing 100. The specific reasons are as follows.

[0134] Among them, as Figure 2 shown, the socket housing 100 includes a cable port 1001 for the cable to extend into. After the cable extends in, it is divided into an L-pole cable, an N-pole cable, and an E-pole cable, and respectively extends into the L-pole wire connection hole 12, the N-pole wire connection hole 13, and the E-pole wire connection hole 14. Among them, in order to facilitate the stripping, routing, and wire pressing of each pole cable, each connection part needs to have a certain distance from the cable port 1001.

[0135] In the related art, the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103 are flush, and the distances of each pole connection part from the cable port 1001 along the length direction (i.e., the second direction Y) are the same (for example, both are D). Assuming that in the terminal 300 provided by the embodiments of the present disclosure, the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103 are also flush, the distances of the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103 from the cable port 1001 still need to be D. However, since the overload protection part 104 is added behind the L-pole connection part 101, the overload protection part 104 protrudes backward relative to the N-pole connection part 102 and the E-pole connection part 103. To accommodate the protruding overload protection part 104, the length of the socket housing 100 needs to be increased.

[0136] In the technical solution provided by the embodiments of the present disclosure, the L-pole connection part 101 protrudes forward relative to the N-pole connection part 102 and the E-pole connection part 103. Then, the distances between the N-pole connection part 102 and the E-pole connection part 103 from the cable port 1001 can still be D, while the distance between the L-pole connection part 101 and the cable port 1001 is d, and d is less than D. In this way, only the distance between the L-pole connection part 101 and the cable port 1001 becomes smaller, which only has some impacts on the stripping, routing, and pressing of the L-pole cable, and has no impact on the N-pole cable and the E-pole cable. Moreover, through actual measurement, the actual wiring experience of the embodiments of the present disclosure is not much different from that of the existing ordinary socket.

[0137] Since the L-pole connection part 101 protrudes forward relative to the N-pole connection part 102 and the E-pole connection part 103, the protruding length of the overload protection part 104 relative to the N-pole connection part 102 and the E-pole connection part 103 backward is reduced (or even does not protrude). And the smaller the protruding length, the easier it is to arrange the newly added overload protection part 104 inside the socket housing 100. Thus, it is beneficial to apply the terminal 300 provided by the embodiments of the present disclosure without increasing the length of the socket housing 100.

[0138] It can be understood that if in the terminal 300 provided by the embodiments of the present disclosure, the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103 are flush, and the distances of each connection part from the cable port 1001 are all d, it will have impacts on the stripping, routing, and pressing of each pole cable, affecting the wiring experience.

[0139] Certainly, in some other examples, in the terminal 300 provided by the embodiments of the present disclosure, along the second direction Y, the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103 can also be flush. The embodiments of the present disclosure do not make specific limitations on this.

[0140] In some examples, as Figure 4 shown, along the second direction Y, the overload protection part 104 protrudes backward relative to the N-pole connection part 102 and the E-pole connection part 103. In this way, the size of the overload protection part 104 along the second direction Y is larger, which is beneficial to arranging the newly added overload protection device. And by setting the overload protection part 104 to protrude backward relative to the N-pole connection part 102 and the E-pole connection part 103, it is beneficial to reduce the size of the L-pole connection part 101 protruding forward relative to the N-pole connection part 102 and the E-pole connection part 103, avoiding the distance between the L-pole connection part 101 and the cable port 1001 of the socket housing 100 being too small, causing difficulties in wiring the L-pole cable.

[0141] The embodiments of the present disclosure do not limit the protruding position of the second conductive sheet 23 from the accommodation cavity 11. Among them, as Figure 4 - Figure 6As shown, the N - pole conductive member 3 extends from the rear of the N - pole wiring portion 102, and the E - pole conductive member 4 extends from the rear of the E - pole wiring portion 103. Then, in some examples, the second conductive sheet 23 of the L - pole conductive member 2 also extends from the rear of the accommodation cavity 11 (or the rear of the overload protection portion 104), that is, directly extends from Figure 5 the opening of the accommodation cavity 11 in

[0142] Among them, since the overload protection portion 104 protrudes rearward relative to the N - pole wiring portion 102 and the E - pole wiring portion 103, if the second conductive sheet 23 directly extends from Figure 5 the opening of the accommodation cavity 11 in

[0143] it will make the inner connection segment of the second conductive sheet 23 be behind the inner connection segment of the N - pole conductive member 3 and the inner connection segment of the E - pole conductive member 4. Among them, the inner connection segment refers to the segment of the conductive member for connecting the socket assembly 200.

[0144] However, generally speaking, in the related art, the inner connection segments of the L - pole conductive member 2, the N - pole conductive member 3, and the E - pole conductive member 4 are all flush. Then, for the above - mentioned setting, it is necessary to adaptively adjust the socket assembly 200. Figure 3 and Figure 4 as shown by the dashed line I in Figure 4 and Figure 5 In some examples, to make the inner connection segment of the L - pole conductive member 2 (i.e., the first inner connection segment 234), the inner connection segment of the N - pole conductive member 3 (i.e., the second inner connection segment 30), and the inner connection segment of the E - pole conductive member 4 (i.e., the third inner connection segment 40) flush (such as Figure 5 As shown, the overload protection portion 104 includes a plurality of side walls. The plurality of side walls can be the first side wall 111, the second side wall 112, the third side wall 113, and the fourth side wall 114 respectively. The first side wall 111 and the second side wall 112 are oppositely arranged, and the first side wall 111 is used to face the bottom (or bottom wall) of the socket. The third side wall 113 and the fourth side wall 114 are oppositely arranged. One end of the plurality of side walls is connected to the N - pole wiring portion 102, and the other end extends rearward. The plurality of side walls and the N - pole wiring portion 102 enclose the accommodation cavity 11. In this way, it is convenient to make the inner connection segments of the L - pole conductive member 2, the N - pole conductive member 3, and the E - pole conductive member 4 flush. Among them, the top wall of the socket is the shell wall where the socket holes are located, and the bottom wall is arranged opposite to the top wall.

[0145] In some examples, as Figure 4 shown, along the third direction Z, the length L1 of the overload protection portion 104 is greater than the length L2 of the L - pole wiring portion 101, the N - pole wiring portion 102, and the E - pole wiring portion 103. In this way, it is beneficial to increase the internal space of the accommodation cavity 11.

[0146] Figure 8 shows a schematic diagram of the terminal block 300. In some examples, such as Figure 8 shown, along the third direction Z, the second side wall 112 of the overload protection part 104 protrudes relative to the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103. Among them, the third direction Z is perpendicular to the first direction X and the second direction Y. The second side wall 112 is disposed opposite to the first side wall 111. In this way, it is beneficial to increase the internal space of the accommodation cavity 11.

[0147] In some examples, along the third direction Z, the first side wall 111 retracts relative to the L-pole connection part 101, the N-pole connection part 102, and the E-pole connection part 103.

[0148] In some examples, such as Figure 2 shown, when the terminal block 300 is installed inside the socket housing 100 in the illustrated posture, the third direction Z is parallel to the thickness direction of the socket.

[0149] In some examples, the bimetal sheet 22 extends along the third direction Z. Among them, the L-pole connection part 101 and the overload protection part 104 are arranged along the second direction Y, which already makes the total length occupied by the L-pole connection part 101 and the overload protection part 104 relatively large. And, in order not to affect the N-pole connection part 102 and the E-pole connection part 103, the dimension of the overload protection part 104 along the first direction X is limited. Therefore, setting the bimetal sheet 22 to extend along the third direction Z can enable the bimetal sheet 22 to have sufficient length. Among them, when a certain component extends along a certain direction, it means that the component is parallel to the direction, or the length direction of the component is the direction. For example, the bimetal sheet 22 extends along the third direction Z, which means that the bimetal sheet 22 is parallel to the third direction Z, or the length direction of the bimetal sheet 22 is the third direction Z.

[0150] When the terminal block 300 is overloaded, the bimetal sheet 22 will disconnect from the target conductive sheet. Among them, the target conductive sheet is the conductive sheet among the first conductive sheet 21 and the second conductive sheet 23 that is in contact connection with the bimetal sheet 22. For example, Figure 7 the second conductive sheet 23 in. And in order to enable the user to continue using the socket after the overload condition is eliminated, the terminal block 300 provided by the embodiment of the present disclosure further includes a reset component 5, and the reset component 5 is configured to, after the bimetal sheet 22 disconnects from the target conductive sheet, under the trigger of the user, make the bimetal sheet 22 reconnect with the target conductive sheet.

[0151] It can be understood that a part of the reset component 5 can be exposed on the outer surface of the socket housing 100 of the socket to facilitate the user to operate the reset component 5 (such as pressing). Exemplarily, such as Figure 1As shown, a part of the reset component 5 is exposed on the jack surface 1000 of the socket housing 100.

[0152] Next, an exemplary implementation of the reset component 5 will be described. Figure 9 A schematic diagram of the reset component 5 and the L - pole conductive member 2 is shown.

[0153] In some examples, as Figure 9 and Figure 5 shown, the reset component 5 includes a reset rod 51 and an elastic member 52. A part of the reset rod 51 is located inside the accommodation cavity 11, and another part is located outside the accommodation cavity 11. The elastic member 52 is located inside the accommodation cavity 11 and abuts against the reset rod 51. Among them, the elastic member 52 is in a compressed state.

[0154] As Figure 10 shown, when the terminal 300 changes from the normal state to the overload state, the bimetallic strip 22 deforms due to the increase in temperature and separates from the target conductive sheet (such as the second conductive sheet 23) to cut off the power supply. After the bimetallic strip 22 separates from the second conductive sheet 23, under the drive of the elastic member 52, the reset rod 51 is inserted between the contacts of the bimetallic strip 22 and the second conductive sheet 23. Thus, it is prevented that, when the overload condition has not been eliminated, the bimetallic strip 22 rebounds due to the temperature drop and comes into contact with the second conductive sheet 23 again. That is, the reset component 5 is also used to prevent the bimetallic strip 22 and the second conductive sheet 23 from automatically coming into contact again after the bimetallic strip 22 separates from the second conductive sheet 23. Among them, the normal state refers to the state where the terminal 300 transmits current normally, and the overload state refers to the state where the terminal 300 is open - circuited. Or it can also be understood that the normal state refers to the state where the current transmitted by the bimetallic strip 22 is lower than the target threshold, so that the bimetallic strip 22 does not deform or has a small amount of deformation, and the bimetallic strip 22 does not separate from the second conductive sheet 23. The overload state refers to the state where the current transmitted by the bimetallic strip 22 is higher than the target threshold, so that the bimetallic strip 22 deforms due to excessive temperature and separates from the second conductive sheet 23.

[0155] As Figure 11 shown, when the overload condition is eliminated, the user presses the reset rod 51. The reset rod 51 compresses the elastic member 52 and withdraws from between the contacts of the bimetallic strip 22 and the second conductive sheet 23. Then the bimetallic strip 22 loses the block of the reset rod 51. Since the temperature of the bimetallic strip 22 has dropped, the bimetallic strip 22 automatically rebounds and comes into contact with the second conductive sheet 23 again, the L - pole conductive member 2 is turned on, and the terminal 300 returns from the overload state to the normal state. The user can use the socket normally.

[0156] Next, an exemplary description of the shape of the reset rod 51 will be given. In some examples, as Figure 9 - Figure 11As shown, the reset rod 51 includes a rod body 511 and a partition rib 512. A part of the rod body 511 is located inside the accommodation cavity 11 and abuts against the elastic member 52, and the other part is located outside the accommodation cavity 11. The partition rib 512 is connected to one side of the rod body 511. Among them, the partition rib 512 is used to be inserted between the bimetal sheet 22 and the contact of the target conductive sheet. Among them, in some examples, the thickness of the partition rib 512 is less than the width of the rod body 511, so that it is beneficial for the partition rib 512 to be inserted between the bimetal sheet 22 and the contact of the target conductive sheet.

[0157] In some examples, such as Figure 10 and Figure 11 As shown, the sliding direction of the reset rod 51 is the same as the extending direction of the bimetal sheet 22. The rod body 511 is located on one side of the bimetal sheet 22 and the target conductive sheet to avoid interfering with the bimetal sheet 22 and the target conductive sheet. The partition rib 512 is located between the bimetal sheet 22 and the target conductive sheet, and can be inserted between the bimetal sheet 22 and the contact of the target conductive sheet, or withdrawn from between the bimetal sheet 22 and the contact of the target conductive sheet under the drive of the rod body 511, so as to complete the switching between the overload state and the normal state.

[0158] In some examples, such as Figure 5 As shown, the rod body 511 is located on the side of the bimetal sheet 22 close to the L-pole wiring hole 12. In this way, in the second direction Y, the rod body 511 and the elastic member 52 do not occupy too much space in the accommodation cavity 11, making the overall volume of the terminal 300 smaller. And because the rod body 511 and the elastic member 52 are close to the bottom 1110 of the accommodation cavity 11, it is also convenient to set corresponding installation structures in the accommodation cavity 11 for installing the reset assembly 5.

[0159] Next, the shape of the bimetal sheet 22 will be described. Figure 12 A side view of the L-pole conductive member 2 and the reset assembly 5 is shown. In some examples, such as Figure 12 As shown, the bimetal sheet 22 sequentially includes a main body section 221, a first bent section 222 and a first connection section 223. Among them, the first connection section 223 is used to connect to the target conductive sheet (such as the second conductive sheet 23), and the first bent section 222 is bent away from the target conductive sheet relative to the first connection section 223. When the terminal 300 is in the normal state, the partition rib 512 is arranged between the main body section 221 and the target conductive sheet and abuts against the first bent section 222. Among them, such as Figure 12 and Figure 9 As shown, the middle part of the main body section 221 is circularly recessed and the periphery is smoothly transitioned.

[0160] Among them, in terms of the design of the first bending section 222, on the one hand, the distance between the main body section 221 and the target conductive sheet is increased, so that there is enough space between the main body section 221 and the target conductive sheet to accommodate the partition rib 512. On the other hand, when the first bending section 222 abuts against the partition rib 512, the first bending section 222 can position the partition rib 512 to prevent the partition rib 512 from directly separating the contact point between the bimetal sheet 22 and the target conductive sheet under the drive of the elastic member 52. When the terminal 300 is in an overload state, the bimetal sheet 22 deforms, causing the first connection section 223 to separate from the target conductive sheet. At this time, the partition rib 512 is no longer positioned by the first bending section 222. Then, under the drive of the elastic member 52, the partition rib 512 extends into the contact between the first connection section 223 and the target conductive sheet.

[0161] In some examples, one end of the main body section 221 away from the first bending section 222 is connected to the non-target conductive sheet among the first conductive sheet 21 and the second conductive sheet 23.

[0162] In other examples, as Figure 12 shown, the bimetal sheet 22 further includes a second connection section 224 and a second bending section 225 connected in sequence. The second bending section 225 is connected to the main body section 221. The second connection section 224 is used to be connected to the non-target conductive sheet among the first conductive sheet 21 and the second conductive sheet 23. The second bending section 225 bends away from the non-target conductive sheet relative to the second connection section 224. In this way, a larger gap can be formed between the main body section 221 and the target conductive sheet, which is beneficial to accommodating the partition rib 512. Among them, in some examples, the second connection section 224 is used to be welded to the non-target conductive sheet (such as the first conductive sheet 21).

[0163] In some examples, as Figure 12 shown, the second conductive sheet 23 includes a fourth L-pole conductive section 231, a fifth L-pole conductive section 232, and a sixth L-pole conductive section 233 connected in sequence. Among them, the fourth L-pole conductive section 231 penetrates the first side wall 111 and is used to be connected to the socket assembly 200. The sixth L-pole conductive section 233 includes a static contact 230 for contacting the moving contact 220 of the bimetal sheet 22. The fifth L-pole conductive section 232 bends away from the bimetal sheet 22 relative to the sixth L-pole conductive section 233 to increase the distance between the fourth L-pole conductive section 231 and the main body section 221.

[0164] The embodiments of the present disclosure do not specifically limit from which side wall of the accommodation cavity 11 the reset rod 51 penetrates. Among them, which side wall of the accommodation cavity 11 the reset rod 51 passes through determines on which outer surface of the socket housing 100 the reset rod 51 is exposed. Among them, the reset rod 51 provided by the embodiments of the present disclosure can penetrate any side wall of the accommodation cavity 11, that is, the reset rod 51 provided by the embodiments of the present disclosure can be exposed on any outer surface of the socket housing 100.

[0165] In some examples, as Figure 1 shown, the reset rod 51 is exposed on the jack surface 1000 of the socket housing 100. Among them, the jack surface 1000 is the surface where the jack is located, and can also be understood as the front surface of the socket. By setting the reset rod 51 to be exposed on the jack surface 1000, the reset rod 51 is made more prominent, which is convenient for reminding the user to operate on the reset rod 51. And, the reset rod 51 will not interfere with the normal placement of the socket.

[0166] Correspondingly, as Figure 8 shown, the reset rod 51 needs to penetrate the second side wall 112 of the accommodation cavity 11, where the second side wall 112 is arranged opposite to the first side wall 111. The first side wall 111 is the side wall penetrated by the second conductive sheet 23. The second side wall 112 is the closest to the jack surface 1000 of the socket housing 100, which is beneficial to realizing the exposure of the reset rod 51 on the jack surface 1000.

[0167] In some examples, as Figure 5 shown, one end of the bimetal sheet 22 is close to the first side wall 111, and the other end is close to the second side wall 112. One end of the bimetal sheet 22 close to the second side wall 112 is connected to the target conductive sheet through a contact. That is, one end of the bimetal sheet 22 close to the second side wall 112 has a moving contact 220. In this way, the length of the reset rod 51 can be reduced, and the possibility of interference between the reset rod 51 and other devices in the accommodation cavity 11 can be reduced.

[0168] In some examples, as Figure 5 shown, the second conductive sheet 23 is the target conductive sheet, and the second conductive sheet 23 is connected to one end of the bimetal sheet 22 close to the second side wall 112 through a contact. That is, the second conductive sheet 23 includes a static contact 230. Correspondingly, the first conductive sheet 21 is fixedly connected (such as welded) to one end of the bimetal sheet 22 close to the first side wall 111.

[0169] Next, the assembly method of the reset assembly 5 in the accommodation cavity 11 will be described.

[0170] In some examples, as Figure 13As shown, the bottom 1110 of the accommodation cavity 11 includes a spring installation groove 115, and the second side wall 112 of the accommodation cavity 11 includes a reset rod through hole 1121, and the reset rod through hole 1121 communicates with the spring installation groove 115. Among them, the spring installation groove 115 is used to accommodate the elastic member 52 (spring) and a part of the reset rod 51. The reset rod through hole 1121 is used for the reset rod 51 to pass through.

[0171] When installing the reset assembly 5, first move the reset rod 51 into the accommodation cavity 11. Then, operate the reset rod 51 so that the rod body 511 of the reset rod 51 passes through the reset rod through hole 1121. Then, install the elastic member 52 so that the elastic member 52 is sleeved around the reset rod 51 and is located in the spring installation groove 115. Under the elastic action of the elastic member 52, the reset rod 51 extends outwards, but due to the existence of the partition rib 512, the reset rod 51 cannot completely extend out of the accommodation cavity 11. Among them, the spring installation groove 115 can also be replaced with a spring installation post and extends into the interior of the elastic member 52.

[0172] Next, the assembly method of the first conductive sheet 21 and the bimetallic sheet 22 in the accommodation cavity 11 will be described.

[0173] In some examples, as Figure 14 shown, the bottom 1110 of the accommodation cavity 11 is provided with a positioning pin 116, and the positioning pin 116 extends along the second direction Y. The first conductive sheet 21 includes a positioning hole 2120, and the positioning pin 116 extends into the positioning hole 2120.

[0174] In some examples, as Figure 14 shown, a partition 117 is provided inside the accommodation cavity 11. Along the first direction X, the partition 117 is arranged between the third side wall 113 and the fourth side wall 114 of the accommodation cavity 11 and is close to the third side wall 113. The first conductive sheet 21 includes a first L-pole conductive section 211, a second L-pole conductive section 212, and a third L-pole conductive section 213 that are connected in sequence. Among them, the first L-pole conductive section 211 is used to be inserted into the L-pole connection hole 12. The second L-pole conductive section 212 is disposed opposite to the bottom 1110 of the accommodation cavity 11, and the second L-pole conductive section 212 is provided with a positioning hole 2120 corresponding to the positioning pin 116. The third L-pole conductive section 213 is parallel to the second direction Y and the third direction Z and is connected to the surface of the partition 117 facing the fourth side wall 114.

[0175] In some examples, the surface of the partition 117 facing the fourth side wall 114 includes a first retaining rib 1171, and a limiting groove is defined between the first retaining rib 1171 and the first side wall 111. The third L-pole conductive section 213 extends into the limiting groove between the first retaining rib 1171 and the first side wall 111.

[0176] When installing the first conductive sheet 21 and the bimetallic sheet 22, it is necessary to first assemble (such as welding) the first conductive sheet 21 and the bimetallic sheet 22, and then insert them as a whole into the accommodation cavity 11 in the direction of the arrow shown in Figure 14 . During the insertion process, auxiliary positioning can be performed through the positioning pin 116 and the positioning hole 2120.

[0177] Next, the assembly method of the second conductive sheet 23 in the accommodation cavity 11 will be described.

[0178] In some examples, as shown in Figure 15 , a second conductive sheet through hole 1111 is provided on the first side wall 111 of the accommodation cavity 11. The second conductive sheet through hole 1111 is used for the second conductive sheet 23 to pass through, and an opening is provided at the rear of the second conductive sheet through hole 1111. Thus, the second conductive sheet 23 can be inserted along the second direction Y.

[0179] In some examples, as shown in Figure 15 , a limiting groove is defined between the partition plate 117 and the third side wall 113, and the second conductive sheet 23 can be inserted into the limiting groove along the second direction Y.

[0180] In some examples, as shown in Figure 15 , one side of the third side wall 113 facing the partition plate 117 includes a second retaining rib 1131, and a limiting groove is formed between the second retaining rib 1131 and the partition plate 117.

[0181] In some examples, as shown in Figure 15 , two third retaining ribs 118 are included inside the accommodation cavity 11. The third retaining ribs 118 extend along the second direction Y, and a limiting groove is defined between the two third retaining ribs 118. As shown in Figure 15 , one end of the second conductive sheet 23 is bent to form a hook portion 2311, and the hook portion 2311 is used to be inserted into the limiting groove between the two third retaining ribs 118 along the second direction Y.

[0182] When installing the second conductive sheet 23, insert the second conductive sheet 23 in the direction indicated by the arrow in Figure 15 , then the second conductive sheet 23 extends between the two third retaining ribs 118, between the partition plate 117 and the second retaining rib 1131, and into the second conductive sheet through hole 1111. Among them, the hook portion 2311 extends into the limiting groove between the two third retaining ribs 118.

[0183] Next, an exemplary description will be given of the assembly method of the N-pole conductive member 3 and the E-pole conductive member 4 in the housing 1.

[0184] In some examples, as shown in Figure 16As shown, the N - pole conductive member 3 includes a first N - pole conductive segment 31, a second N - pole conductive segment 32, and a third N - pole conductive segment 33 that are connected in sequence. These three conductive segments are bent. The first N - pole conductive segment 31 extends along the second direction Y and extends into the N - pole connection hole 13.

[0185] There are two opposite first clamping positions 1021 on the outer wall of the housing 1.

Correspondingly, along the first direction X, first protrusions 321 are respectively provided on the two side walls of the second N - pole conductive segment 32. The two first protrusions 321 respectively extend into the two first clamping positions 1021, thereby realizing the limit of the second N - pole conductive segment 32. Among them, one first clamping position 1021 can be located on the side wall of the accommodation cavity 11.

[0186] There is also a second clamping position 1022 on the side wall of the housing 1. In the third direction Z, the third N - pole conductive segment 33 has a second protrusion 331, and the second protrusion 331 is located in the second clamping position 1022, thereby realizing the limit of the third N - pole conductive segment 33.

[0187] In some examples, as Figure 16 shown, the E - pole conductive member 4 includes a first E - pole conductive segment 41, a second E - pole conductive segment 42, and a third E - pole conductive segment 43 that are connected in sequence, and the first E - pole conductive segment 41 is located in the E - pole connection hole 14. The shape of the E - pole conductive member 4 is substantially the same as that of the N - pole conductive member 3, which will not be elaborated here.

[0188] Correspondingly, to realize the limit of the E - pole conductive member 4, there are two opposite third clamping positions 1031 on the side wall of the housing 1. The two third clamping positions 1031 are arranged along the first direction X and are located on both sides of the E - pole connection hole 14. Along the first direction X, third protrusions 421 are respectively provided on the two side walls of the second E - pole conductive segment 42. The two third protrusions 421 respectively extend into the third clamping positions 1031 to realize the limit of the second E - pole conductive segment 42. Among them, one third clamping position 1031 can be located on the side wall of the accommodation cavity 11.

[0189] And, there is also a fourth clamping position 1032 on the outer wall of the housing 1. In the third direction Z, the third E - pole conductive segment 43 has a fourth protrusion 431, and the fourth protrusion 431 is located in the fourth clamping position 1032 to realize the limit of the third E - pole conductive segment 43.

[0190] In some examples, as Figure 17As shown, the terminal block 300 provided by the embodiments of the present disclosure further includes a cover plate 6, and the cover plate 6 can be used to close the opening of the accommodation cavity 11. Next, the connection manner between the cover plate 6 and the housing 1 will be described by way of example.

[0191] In some examples, the cover plate 6 is snap-fitted with the housing 1.

[0192] In some examples, as Figure 17 and Figure 18 shown, the cover plate 6 includes a plate body 61 and two snap-fasteners 62, and the two snap-fasteners 62 are located on one side of the plate body 61 facing the bottom 1110 of the accommodation cavity 11. The cavity wall of the accommodation cavity 11 includes two snap holes 110. The two snap-fasteners 62 of the cover plate 6 are respectively snap-fitted with the two snap holes 110.

[0193] In some examples, as Figure 17 shown, the two snap-fasteners 62 are opposite to each other, and the two snap holes 110 are also opposite to each other.

[0194] In some examples, as Figure 17 shown, the two snap holes 110 are respectively arranged on the first side wall 111 and the second side wall 112 of the accommodation cavity 11.

[0195] In order to make the connection between the cover plate 6 and the housing 1 more stable and facilitate the positioning of the cover plate 6, in some examples, as Figure 17 shown, the cover plate 6 further includes a positioning post 63, and the positioning post 63 is located on one side of the plate body 61 facing the bottom 1110 of the accommodation cavity 11. The inside of the accommodation cavity 11 includes a receiving groove 119 for receiving the positioning post 63.

[0196] In some examples, as Figure 17 shown, the receiving groove 119 is connected to the fourth side wall 114.

[0197] In some examples, the positioning post 63 is in close fit (such as interference fit) with the receiving groove 119, so that the connection between the cover plate 6 and the housing 1 is more stable.

[0198] In some examples, as Figure 17 and Figure 18 shown, the cover plate 6 includes a limiting rib 64, and the limiting rib 64 is located on one side of the plate body 61 facing the bottom 1110 of the accommodation cavity 11 and extends into the inside of the accommodation cavity 11. Among them, the limiting rib 64 is used to limit the position of the bimetal sheet 22 to prevent the bimetal sheet 22 from shaking.

[0199] In some examples, the limiting rib 64 is opposite to the connection part of the bimetal sheet 22 and the first conductive sheet 21, is located on the side of the bimetal sheet 22 facing away from the first conductive sheet 21, and contacts the bimetal sheet 22 to limit the bimetal sheet 22.

[0200] Next, with reference to the above content, an exemplary description of the assembly sequence of the L - pole conductive member 2 and the reset assembly 5 will be given.

[0201] In the first step, please refer to Figure 13 , and install the reset assembly 5 on the housing 1. In the second step, please refer to Figure 14 , and insert the first conductive sheet 21 and the bimetallic sheet 22 as a whole into the interior of the receiving cavity 11 in the direction of the arrow shown in the figure. In the third step, please refer to Figure 15 , insert the second conductive sheet 23 into the interior of the receiving cavity 11 in the direction of the arrow shown in the figure, and operate the reset rod 51 so that the partition rib 512 of the reset rod 51 abuts against the first bent section 222 of the bimetallic sheet 22. In the fourth step, please refer to Figure 17 , and use the cover plate 6 to close the opening of the receiving cavity 11.

[0202] Among them, the assembly of the N - pole conductive member 3 and the E - pole conductive member 4 is relatively independent compared with the assembly of the L - pole conductive member 2 and the reset assembly 5. Therefore, the assembly of the N - pole conductive member 3 and the E - pole conductive member 4 can be carried out before, after or during the assembly of the L - pole conductive member 2 and the reset assembly 5. Similarly, the L - pole wire pressing assembly 7, the N - pole wire pressing assembly 8 and the E - pole wire pressing assembly 9 in this disclosure embodiment can be assembled at the end.

[0203] It should be noted that the above - mentioned first conductive sheet 21, bimetallic sheet 22, second conductive sheet 23, reset assembly 5 and corresponding structural members form an overload protection mechanism or an overload protector, and this overload protector is integrated in the terminal block 300, so that the terminal block 300 has an overload protection function. In some other examples, the marketed overload protector can also be used alone, that is, it is not integrated with the terminal block 300, and this overload protector can be separately arranged inside the socket.

[0204] Correspondingly, the embodiment of the present disclosure also provides an overload protector. Please refer to Figure 5 - Figure 6 and Figure 9 - Figure 12 , the overload protector includes a housing 1, a first conductive sheet 21, a bimetallic sheet 22, a second conductive sheet 23, a reset rod 51 and an elastic member 52. Among them, the housing 1 can be a housing independent of the terminal block 300. The housing 1 includes a receiving cavity 11, and the bimetallic sheet 22 is located in the receiving cavity 11.

[0205] One end of the first conductive sheet 21 is located outside the receiving cavity 11 for wiring, and the other end extends into the interior of the receiving cavity 11 and is fixedly connected to one end of the bimetallic sheet 22. The other end of the bimetallic sheet 22 is connected to one end of the second conductive sheet 23 through a contact. The other end of the second conductive sheet 23 extends out of the receiving cavity 11 for wiring.

[0206] As shown in Figure 9 - Figure 12As shown, the bimetal sheet 22 and the second conductive sheet 23 are arranged in parallel and both extend along the third direction Z. The reset rod 51 includes a rod body 511 and a partition rib 512. The rod body 511 is slidably connected to the housing 1 along the third direction Z and abuts against the elastic member 52. The partition rib 512 is connected to one side of the rod body 511 and is arranged between the bimetal sheet 22 and the second conductive sheet 23.

[0207] As Figure 10 shown, when the overload protector changes from the normal state to the overload state, the bimetal sheet 22 and the second conductive sheet 23 are disconnected. The elastic member 52 drives the partition rib 512 to insert between the contacts of the bimetal sheet 22 and the second conductive sheet 23. When the reset rod 51 is pressed, the partition rib 512 is withdrawn from between the contacts of the bimetal sheet 22 and the second conductive sheet 23, and the bimetal sheet 22 and the second conductive sheet 23 are reconnected.

[0208] It should be noted that for the specific structures and installation methods and other related technical features of the first conductive sheet 21, the bimetal sheet 22, the second conductive sheet 23, the reset rod 51, and the elastic member 52, reference can be made to the foregoing content and will not be elaborated here. The difference between the overload protector provided in the embodiments of the present disclosure and the foregoing terminal 300 is that the overload protector does not include the above-mentioned respective connection parts. It can be understood that the above-mentioned overload protection part 104 can be understood as the housing 1, and the overload protection part 104 and each device assembled on the overload protection part 104 can be understood as an overload protector.

[0209] In addition to the foregoing overload protector, the embodiments of the present disclosure also provide an overload protector in another implementation manner, which can be integrated in the terminal 300 or used alone.

[0210] Next, an exemplary description will be given of the terminal 300 integrated with another overload protector.

[0211] Figure 19 The external view of another terminal 300 is shown. Figure 20 The schematic diagram of the terminal 300 in the normal state is shown, Figure 21 The schematic diagram of the terminal 300 in the overload state is shown, Figure 22 The schematic diagram of the terminal 300 switching from the overload state to the normal state is shown.

[0212] As Figure 20 - Figure 22As shown, the terminal 300 includes a housing 1, a first conductive sheet 21, a bimetallic sheet 22, and a second conductive sheet 23. The housing 1 includes an L-pole connection hole 12 and a receiving cavity 11. One end of the first conductive sheet 21 extends into the L-pole connection hole 12, and the other end extends into the receiving cavity 11 and is connected to one end of the bimetallic sheet 22. The other end of the bimetallic sheet 22 is connected to one end of the second conductive sheet 23, and the other end of the second conductive sheet 23 extends out of the receiving cavity 11 and is used to connect to the L-pole socket assembly 201. Among them, the bimetallic sheet 22 includes a moving contact 220, and the second conductive sheet 23 includes a static contact 230.

[0213] As Figure 20 shown, in the normal state, the moving contact 220 and the static contact 230 are in contact. As Figure 21 shown, in the overload state, the bimetallic sheet 22 is deformed by heat, so that the moving contact 220 and the static contact 230 are separated.

[0214] To avoid the bimetallic sheet 22 automatically rebounding after the temperature drops and the moving contact 220 and the static contact 230 re-connecting under the premise that the overload condition has not been eliminated. In some examples, as Figure 20 - Figure 22 shown, the terminal 300 further includes a pressure assembly 10. The pressure assembly 10 is connected to the bimetallic sheet 22 and is configured to provide a force that makes the moving contact 220 approach the static contact 230 when the moving contact 220 contacts the static contact 230, and, after the moving contact 220 and the static contact 230 are separated, keep the moving contact 220 in the current position to prevent the bimetallic sheet 22 from automatically rebounding and reconnecting with the second conductive sheet 23.

[0215] In some examples, as Figure 20 - Figure 22 shown, the pressure assembly 10 includes a screw 10a and a spring piece 10b. The screw 10a is connected to the housing 1, one end of the spring piece 10b is connected to the screw 10a, and the other end is connected to the bimetallic sheet 22.

[0216] After the spring piece 10b is assembled, it is always in an elastically deformed state, that is, the spring piece 10b always exerts an elastic force on the bimetallic sheet 22. Among them, when the moving contact 220 contacts the static contact 230, at least a part of the elastic force provided by the spring piece 10b is towards the static contact 230, so that the moving contact 220 is in close contact with the static contact 230. When the moving contact 220 and the static contact 230 are separated, at least a part of the elastic force provided by the spring piece 10b is away from the static contact 230, so that the moving contact 220 and the static contact 230 remain in the separated state. Among them, by rotating the screw 10a, the elastic force exerted by the spring piece 10b on the bimetallic sheet 22 can be adjusted.

[0217] In order to enable the user to continue using the socket after the overload condition is eliminated. As Figure 20 - Figure 22As shown, the terminal 300 further includes a reset assembly 5. As Figure 20 - Figure 22 shown, the reset assembly 5 includes a reset rod 51 and an elastic member 52.

[0218] The reset rod 51 is installed on the housing 1 and can move relative to the housing 1. The bimetal 22 and / or the moving contact 220 are located on the moving path of the reset rod 51. Thus. As Figure 21 shown, when the user presses the reset rod 51 and applies a pressing force Fn, the reset rod 51 can move in the direction close to the bimetal 22 and / or the moving contact 220 under the action of the pressing force Fn until it abuts against the bimetal 22 and / or the moving contact 220, and continues to push the bimetal 22 and the moving contact 220 to move until the bimetal 22 can break the balance and drive the moving contact 220 to contact the static contact 230 based on its own deformation force.

[0219] The elastic member 52 is used to drive the reset rod 51 back to the initial position when it is not pressed after the reset rod 51 is pressed. Exemplarily, the elastic member 52 is a spring, and the two ends of the spring are respectively connected to the inner wall of the housing 1 and one end of the reset rod 51 close to the moving contact 220. As Figure 22 shown, when the reset rod 51 is pressed, the spring is stretched and deformed. When the pressing force is removed, the reset rod 51 returns to the initial position when it is not pressed under the elastic force of the spring.

[0220] The above are only optional embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principle of the present disclosure shall be included in the protection scope of the present disclosure.
