Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electrical equipment, and in particular to a wiring terminal and a socket strip. Background Art

[0002] Socket strips are electrical accessories commonly used in people's lives. People connect the socket strips to fixed sockets and supply power to household appliances through the sockets on the socket strips.

[0003] A power strip usually includes a cover, a bottom shell, a socket assembly, wiring terminals and a connecting strip. The connecting strip is a current-carrying component, one end of which is connected to the wiring terminal, and the other end is connected to the socket assembly. The part where the connecting strip connects to the wiring terminal is used to electrically connect to the power cord when the power cord is connected to the wiring terminal to energize the power strip; the part where the connecting strip connects to the socket assembly is used to connect to the plug of a household appliance to energize the household appliance.

[0004] In the related art, the structures of the wiring terminals corresponding to power strips of different specifications are also different, so the connecting strips need to be bent into different shapes to connect with the wiring terminals, which makes the connecting strips unable to be universal. Utility Model Content

[0005] In view of the above problems, an embodiment of the present application provides a wiring terminal and a power strip, which can realize the universality of connecting strips, thereby helping to improve the production efficiency of the power strip.

[0006] According to one aspect of the embodiment of the present application, a wiring terminal is provided, which is used for a power strip, and the wiring terminal includes a terminal box, a terminal cover, a terminal and a connector. The terminal box includes a receiving cavity, one end of which is open; the terminal cover is arranged at the opening at one end of the receiving cavity; the terminal is arranged in the receiving cavity; one end of the connector is located in the terminal, and the other end is located outside the terminal box, and is used to connect with the connecting strip in the power strip.

[0007] By adopting the above scheme, the connection strip is connected to the end of the connector outside the terminal box, so that the connection strip and the terminal block can be connected. When producing power strips of different specifications, it is only necessary to change the shape and position of the connector so that the connector can adapt to the power strips of the corresponding specifications, and the connection strip does not need to be replaced, so it can be used in power strips of various specifications. Moreover, after such a setting, the terminal block can be pre-assembled, and then the terminal block as a whole can be assembled with the connection strip. In this way, even in power strips of different specifications, the connection method between the connection strip and the terminal block is unified, which is conducive to the automated production of the power strip and can improve the production efficiency of the power strip.

[0008] In some embodiments, a positioning groove is provided on the outer wall of the terminal box, and the connector is partially located in the positioning groove.

[0009] By adopting the above scheme, the positioning groove can locate the position of the connector so that the part of the connector located outside the terminal box will not swing at will, so that the connector and the connecting strip can be well aligned during the assembly process of the terminal and the connecting strip, and the two can be reliably connected.

[0010] In some embodiments, a limiting rib is provided on the first outer wall of the terminal box, the connecting piece partially protrudes from the first outer wall, and an accommodating groove is formed between the limiting rib and the part of the connecting piece protruding from the first outer wall, and the accommodating groove is used to accommodate the connecting strip; the first outer wall is any outer wall of the terminal box.

[0011] By adopting the above scheme, when assembling the wiring terminal and the connecting strip, the connecting strip can be partially placed in the accommodating groove to realize the positioning of the connecting strip; and, since one of the groove walls of the accommodating groove is a connecting piece, when the connecting strip is partially placed in the accommodating groove, the position between the connecting strip and the connecting piece is relatively fixed and close to each other, which is convenient for the staff to connect the connecting strip and the connecting piece. The structure after the connecting strip and the connecting piece are connected is also relatively firm, and the two are not easy to loosen or separate.

[0012] In some embodiments, a support rib is provided on the terminal cover, the support rib is provided on one side of the connector, and the distance between the support rib and the connector is less than a first preset distance to support the connector.

[0013] By adopting the above solution, the supporting ribs support the connecting piece, so that the structure of the connecting piece is more stable, the position is more firm, and it is not easy to deform and shake.

[0014] In some embodiments, a first socket is provided on the terminal box, and the connector passes through the terminal box from the first socket; a support rib is provided on the terminal cover, the support rib is at least partially located at the first socket, and the distance between the support rib and the connector is less than a second preset distance to support the connector.

[0015] By adopting the above solution, since the distance between the support rib and the connecting piece is less than the second preset distance, when the connecting piece is deformed in the direction of the support rib after being subjected to force, the support rib can prevent further deformation of the connecting piece, thereby preventing the connecting piece from excessive deformation or breakage.

[0016] In some embodiments, the terminal box is further provided with a second socket, the second socket is used to insert the wire, and the second socket is at least partially opposite to the supporting rib to prevent the wire from passing through the first socket.

[0017] When connecting a wire to a terminal, the user needs to insert the wire from the second socket into the terminal box, and further insert it into the terminal to connect the wire to the connector. In the process of inserting the wire, it is often difficult for the user to determine whether the wire is inserted in place. The wire may be inserted too deep and come out of the first socket, or the wire may be inserted too shallow and the connection with the connector is not firm. After the support ribs are set, the user can determine whether the wire is inserted in place based on whether the wire is blocked by the support ribs, and the problem of the wire coming out of the first socket will not occur.

[0018] In some embodiments, a first limiting protrusion is provided on the inner wall of the terminal box, a second limiting protrusion is provided on the outer wall of the terminal, and the first limiting protrusion is located on a side of the second limiting protrusion close to the opening of the terminal box.

[0019] By adopting the above solution, after the terminal is installed into the accommodating cavity from one side of the opening of the terminal box, the second limiting protrusion is blocked by the first limiting protrusion, so that the terminal is not easy to escape from the opening of the terminal box.

[0020] In some embodiments, the terminal block also includes a fastener connected to the side wall of the terminal box, and one end of the fastener is located in the accommodating cavity and is threadedly connected to the terminal. The fastener can rotate to drive the terminal to move, and the movement of the terminal drives the wire inserted into the terminal to move so that the wire contacts the connector.

[0021] By adopting the above solution, when the connector is stationary, the terminal is driven to move by the rotation of the fastener, and when the wire is inserted into the terminal, the wire will also move with the movement of the terminal, and finally the wire will contact the connector to achieve electrical connection between the connector and the wire. The terminal block of this structure is simple in structure and convenient in wiring operation.

[0022] In some embodiments, there are multiple fasteners, insulating isolation ribs are provided between the multiple fasteners, and / or, a sink is provided on the terminal box, and the end of the fastener is located in the sink, and / or, a limit buckle is provided on the terminal box, and the end of the fastener is located on the side of the limit buckle close to the inside of the terminal box.

[0023] Insulating isolation ribs are provided between multiple fasteners, so that the electrical clearance and creepage distance between different fasteners are increased, and short circuits are not easy to occur between different fasteners. The end of the fastener is located in the sink, and the side wall of the sink can limit the position of the fastener to prevent the fastener from shaking in the sink, and the side wall of the sink can also isolate multiple fasteners to prevent adjacent fasteners from being too close to each other and causing short circuits. A limit buckle is provided on the terminal box, and the end of the fastener is located on the side of the limit buckle close to the terminal box. The limit buckle limits the position of the fastener, making it difficult for the fastener to move outside the terminal box and detach from the terminal box, and can prevent the ends of multiple fasteners exposed outside the terminal box from being too long and too close to each other, thereby preventing short circuits between multiple fasteners.

[0024] According to another aspect of an embodiment of the present application, a power strip is provided, comprising the wiring terminal and a connecting strip in any of the above embodiments, wherein the connecting strip is connected to a connecting piece of the wiring terminal.

[0025] Since the connecting strip and the connecting piece are not integrated, the connecting strip can be used in sockets of different specifications, and only the connecting piece part needs to be changed to adapt to different sockets. In addition, for sockets of different specifications, the connection method between the connecting strip and different connecting pieces can remain unchanged, which is convenient for the automated production of the sockets.

[0026] To summarize, the present application provides a terminal block including a connector, and enables the connector to be connected to a connecting strip outside a terminal box. This allows for the production of power strips of different specifications by only changing the shape and position of the connector so that the connector can adapt to the power strips of corresponding specifications, while the connecting strip does not need to be replaced. This enables the connecting strip to be used in power strips of various specifications, which is beneficial to the automated production of power strips and improves the production efficiency of the power strips.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0037] The terms "comprising" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover but not exclude other contents. The word "a" or "an" does not exclude the presence of a plurality.

[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0040] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the terminal block or power strip of the present application. For example, in the description of the present application, the directions or positional relationships indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application.

[0041] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two groups (including two).

[0043] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection; the physical connection may also be an integral connection, for example, a connection formed by welding, bonding or integral molding.

[0044] A power strip usually includes a cover, a bottom shell, a socket assembly, wiring terminals and a connecting strip. The connecting strip is a current-carrying component, one end of which is connected to the wiring terminal, and the other end is connected to the socket assembly. The part where the connecting strip connects to the wiring terminal is used to electrically connect to the power cord when the power cord is connected to the wiring terminal to energize the power strip; the part where the connecting strip connects to the socket assembly is used to connect to the plug of a household appliance to energize the household appliance.

[0045] In the related art, the connecting strip and the wiring terminal are manufactured separately, and finally the two are assembled when the power strip is assembled. During assembly, since the structures of the wiring terminals corresponding to power strips of different specifications are also different, the connecting strip needs to be bent into different shapes to be assembled with the wiring terminals, which makes the connecting strip unable to be universal and unable to be automatically produced.

[0046] In view of this, the present application provides a wiring terminal 100, which is used for a power strip. Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of a wiring terminal in an embodiment of the present application from a first viewing angle. Figure 2 for Figure 1 Schematic diagram of the cross-section structure along section AA.

[0047] like Figure 1 and Figure 2 As shown, the wiring terminal 100 provided in the present application includes a terminal box 110, a terminal cover 120, a terminal 130 and a connector 140. The terminal box 110 includes a receiving chamber 111, one end of which is open; the terminal cover 120 is disposed at the opening at one end of the receiving chamber 111; the terminal 130 is disposed in the receiving chamber 111; one end of the connector 140 is located in the terminal 130, and the other end is located outside the terminal box 110, and is used to connect with the connecting strip in the power strip.

[0048] The terminal box 110 and the terminal cover 120 are both made of insulating materials. Personnel can install the terminals 130 and the connectors 140 into the terminal box 110 from the opening of the terminal box 110, and then cover the terminal cover 120 on the opening of the terminal box 110 to complete the assembly of the terminal block 100.

[0049] Optionally, the terminal box 110 and the terminal cover 120 may be fixed in a simple manner, for example, Figure 2 As shown, a buckle hole 150 is disposed on one of the terminal box 110 and the terminal cover 120 , and a buckle platform 160 is disposed on the other. The buckle platform 160 is disposed in the buckle hole 150 to limit the separation of the terminal box 110 and the terminal cover 120 .

[0050] The terminal 130 is a metal part, and one terminal 130 may have only one wire installation position or multiple wire installation positions. Accordingly, the number of connectors 140 may be set according to the number and specific positions of the wire installation positions on the terminal 130. For example, three wire installation slots are arranged in a row on the terminal 130, which are used to install a neutral wire, a live wire, and a ground wire respectively. A connector 140 is arranged corresponding to each of the three wire installation slots, and those skilled in the art may set them according to actual conditions.

[0051] Compared with the terminal blocks in the related art, the terminal blocks 100 in the embodiment of the present application are provided with a connecting piece 140. Thus, when the terminal blocks 100 are installed in a power strip, the connecting strip 400 in the power strip does not need to be bent into a shape that matches the internal structure of the terminal blocks 100 to connect with the terminal blocks 100. Instead, the connecting strip 400 is connected to one end of the connecting piece 140 extending out of the terminal box 110 to achieve electrical connection between the connecting strip and the terminal blocks 100.

[0052] When producing power strips of different specifications, only the shape and position of the connecting member 140 need to be changed so that the connecting member 140 can adapt to the power strip of the corresponding specifications, and the connecting strip 400 does not need to be replaced, so it can be used universally in power strips of various specifications.

[0053] In addition, after such a configuration, the terminal block 100 can be pre-assembled, and then the terminal block 100 can be assembled as a whole with the connecting strip. In this way, even in power strips of different specifications, the connection method between the connecting strip and the terminal block 100 is unified, which is conducive to the automated production of the power strip and can improve the production efficiency of the power strip.

[0054] The installation of the connector 140 and other components of the terminal block 100 requires a certain degree of fixation.

[0055] Please continue to refer to Figure 1 Optionally, in some embodiments, a positioning groove 170 is provided on the outer wall of the terminal box 110 , and a portion of the connector 140 is located in the positioning groove 170 .

[0056] The positioning groove 170 can be a groove-like structure formed by directly cutting a groove on the outer wall of the terminal box 110, or it can be a groove-like structure on a component set on the outer wall of the terminal box 110 with multiple protrusions set on the outer wall of the terminal box 110 to form a groove-like channel between adjacent protrusions, or it can be a groove-like structure on a component set on the outer wall of the terminal box 110.

[0057] In addition, the number of the positioning grooves 170 may be one or more, and the multiple positioning grooves 170 may position the connector 140 at different curved sections of the connector 140, or may position the connector 140 at different positions of the same curved section of the connector 140. This embodiment of the application is not limited to this.

[0058] The positioning groove 170 can position the connector 140 so that the portion of the connector 140 outside the terminal box 110 will not swing at will, thereby allowing the connector 140 and the connecting strip to be well aligned during assembly of the terminal block 100 and the connecting strip, and facilitating reliable connection between the two.

[0059] Figure 3 This is a schematic diagram of the structure of a wiring terminal provided in an embodiment of the present application from a second viewing angle. Figure 3 As shown, in some embodiments, a limiting rib 180 is provided on the first outer wall 190 of the terminal box 110, and a portion of the connecting member 140 protrudes from the first outer wall 190. An accommodating groove 181 is formed between the limiting rib 180 and the portion of the connecting member 140 protruding from the first outer wall 190, and the accommodating groove 181 is used to accommodate the connecting strip; the first outer wall 190 is any outer wall of the terminal box 110.

[0060] The first outer wall 190 is any outer wall of the terminal box 110 , and the first outer wall 190 is the surface through which the connecting strip and the connecting member 140 are to be connected or through which the connecting strip 190 is to be extended.

[0061] On the first outer wall 190, the limiting ribs 180 and the connector 140 may be directly opposite to each other, or may be arranged non-directly opposite to each other on both sides of the receiving groove 181. A surface of the connector 140 close to the receiving groove 181 is equivalent to the side wall of the receiving groove 181. When the wiring terminal 100 and the connecting strip are assembled, the connecting strip is partially placed in the receiving groove 181. At this time, the connecting strip and the connector 140 are close to or in contact with each other, which is convenient for personnel to connect the connecting strip and the connector 140. In addition, during the connection process, the connecting strip is not easy to move, and the structure after the connecting strip and the connector 140 are connected is also relatively firm, and the two are not easy to loosen or separate.

[0062] Please continue to refer to Figure 1 In some embodiments, a support rib 200 is provided on the terminal cover 120 , the support rib 200 is provided on one side of the connector 140 , and a distance between the support rib 200 and the connector 140 is less than a first preset distance to support the connector 140 .

[0063] The first preset distance is a distance that enables the support rib 200 to support the connector 140. This distance is smaller than the maximum distance that the connector 140 is allowed to move in the direction close to the support rib 200. For example, the connector 140 is allowed to have a maximum displacement of 2 mm (millimeter) in the direction close to the support rib 200 (caused by movement or deformation of the connector 140). If the displacement exceeds 2 mm, it will affect the assembly of the connector 140 and the connecting strip. At this time, the first preset distance is any distance less than or equal to 2 mm, so that the connector 140 can be stably located in a suitable position under the support of the support rib 200.

[0064] It can be seen that the support ribs 200 support the connection member 140, so that the structure of the connection member 140 is more stable, the position is more firm, and it is not easy to deform and shake.

[0065] Figure 4 for Figure 3 Schematic diagram of the cross-section structure along the BB section. Please refer to Figure 1 and Figure 4 In some embodiments, a first socket 210 is provided on the terminal box 110, and the connector 140 passes through the terminal box 110 from the first socket 210; a support rib 220 is provided on the terminal cover 120, and the support rib 220 is at least partially located in the first socket 210, and the distance between the support rib 220 and the connector 140 is less than the second preset distance to support the connector 140.

[0066] The second preset distance is a distance that enables the support rib 220 to support the connector 140. This distance is smaller than the maximum distance that the connector 140 is allowed to move in the direction close to the support rib 220. For example, the connector 140 is allowed to have a maximum displacement of 3 mm in the direction close to the support rib 220 (caused by movement or deformation of the connector 140). If the displacement exceeds 3 mm, the electrical connection between the connector 140 and the terminal 130 will be affected. At this time, the second preset distance is any distance less than or equal to 3 mm, so that the connector 140 can pass through the fixed position at the first socket 210 under the support of the support rib 220.

[0067] The first socket 210 is generally larger to facilitate installation of the connector 140 . This makes it difficult for the side wall of the first socket 210 to properly limit the connector 140 after the connector 140 is installed in the terminal box 110 , and the connector 140 is more likely to shake.

[0068] In the present application, after the connector 140 is installed in the terminal box 110, the terminal cover 120 is covered on the opening of the terminal box 110, and the support rib 220 on the terminal cover 120 is located on one side of the connector 140. Since the distance between the support rib 220 and the connector 140 is less than the second preset distance, when the connector 140 is deformed in the direction of the support rib 220 after being subjected to force, the support rib 220 can prevent further deformation of the connector 140, thereby preventing the connector 140 from excessive deformation or even breakage.

[0069] Please refer to Figure 3 and Figure 4 In some embodiments, the terminal box 110 is further provided with a second socket 230 for inserting a wire. The second socket 230 is at least partially opposite to the support rib 220 to prevent the wire from passing through the first socket 210 .

[0070] When connecting a wire to the terminal block 100, the user needs to insert the wire from the second socket 230 into the terminal box 110, and further insert the wire into the terminal 130 to connect the wire to the connector 140. During the process of inserting the wire, it is often difficult for the user to determine whether the wire is inserted in place. The wire may be inserted too deeply and pass out from the first socket 210, or the wire may be inserted too shallowly and the connection between the wire and the connector 140 is not firm.

[0071] When the second socket 230 is at least partially opposite to the support rib 220, the user can determine whether the wire is inserted into place based on whether the wire is blocked by the support rib 220, and there will be no problem of the wire coming out of the first socket 210, which is beneficial to ensuring the reliability and safety of the electrical connection when the power strip is in use.

[0072] Please refer to Figure 2 In some embodiments, a first limiting protrusion 240 is provided on the inner wall of the terminal box 110, and a second limiting protrusion 250 is provided on the outer wall of the terminal 130. The first limiting protrusion 240 is located on the side of the second limiting protrusion 250 close to the opening of the terminal box 110.

[0073] When assembling the terminal block, after the terminal 130 is installed into the accommodating cavity 111 from the opening side of the terminal box 110, the second limiting protrusion 250 is blocked by the first limiting protrusion 240, so that the terminal 130 is not easy to escape from the opening of the terminal box 110, which is conducive to further assembling the terminal box 110 and the terminal 130 with other components.

[0074] After the terminal block is assembled, since the opening of the terminal box 110 is closed by the terminal cover 120, the terminal cover 120 mainly serves to limit the position of the terminal 130 in the accommodating cavity 111, and the first limiting protrusion 240 and the second limiting protrusion 250 can prevent the terminal 130 from falling out of the opening of the terminal box 110 when the terminal cover 120 is loose or damaged.

[0075] It can be understood that when the first limiting protrusion 240 and the second limiting protrusion 250 are provided, since the first limiting protrusion 240 and the second limiting protrusion 250 partially replace the function of the terminal cover 120, the terminal block may not include the terminal cover 120, thereby simplifying the structure of the terminal block and reducing the volume and weight of the terminal block.

[0076] In other words, when the connecting terminal includes the terminal cover 120, the first limiting protrusion 240 and the second limiting protrusion 250 may or may not be provided; when the connecting terminal does not include the terminal cover 120, the connecting terminal must include the above-mentioned structure of the first limiting protrusion 240 and the second limiting protrusion 250.

[0077] Optionally, a side of the first limiting protrusion 240 close to the opening of the terminal box 110 is set as an inclined surface, and / or a side of the second limiting protrusion 250 away from the opening of the terminal box 110 is set as an inclined surface.

[0078] During the process of inserting the terminal 130 from the opening of the terminal box 110, the first limiting protrusion 240 and the second limiting protrusion 250 may contact each other through at least one inclined surface, which may be located on the first limiting protrusion 240, or on the second limiting protrusion 250, or the surfaces of the first limiting protrusion 240 and the second limiting protrusion 250 that contact each other may all be inclined surfaces. After contact, the first limiting protrusion 240 and the second limiting protrusion 250 squeeze each other, so that the side wall of the terminal box 110 and / or the side wall of the terminal 130 gradually produce elastic deformation, which is conducive to the terminal 130 being inserted into the terminal box 110. After the first limiting protrusion 240 and the second limiting protrusion 250 are out of contact, the side wall of the terminal box 110 and / or the side wall of the terminal 130 return to their original shape, the terminal 130 is installed in place, the first limiting protrusion 240 and the second limiting protrusion 250 limit each other, and the terminal 130 is not easy to fall out of the opening of the terminal box 110.

[0079] The wiring terminal 100 disclosed in the present application can be connected to the wiring terminal 100 in a variety of ways. Figure 2 and Figure 3 As shown, in some embodiments, the terminal block 100 also includes a fastener 260, which is connected to the side wall of the terminal box 110, and one end of the fastener 260 is located in the accommodating cavity 111 and is threadedly connected to the terminal 130. The fastener 260 can rotate to drive the terminal 130 to move, and the movement of the terminal 130 drives the wire inserted into the terminal 130 to move so that the wire contacts the connector 140.

[0080] The fastener 260 can be a screw or a similar part of a screw. Taking the fastener 260 as a screw as an example, the screw is rotatably connected to the side wall of the terminal box 110 and can be axially rotated relative to the side wall of the terminal box 110, while the screw is fixed relative to the terminal box 110 in the axial direction. The stud part of the screw passes through the side wall of the terminal box 110 and is located in the accommodating cavity 111, and the stud part is threadedly connected to the terminal 130.

[0081] For example, please refer to Figure 2The terminal 130 may include a connecting wall 131, a crimping wall 132, and an intermediate wall 133 disposed between the connecting wall 131 and the crimping wall 132. The fastener 260 is threadedly connected to the connecting wall 131. The connecting member 140 is inserted between the connecting wall 131 and the crimping wall 132 and is located directly opposite to the fastener 260, so that the connecting member 140 and the fastener 260 are mutually limited. When connecting a wire, the wire is inserted between the connecting wall 131 and the crimping wall 132, and then the fastener 260 is rotated so that the fastener 260 drives the terminal 130 to move. The direction in which the terminal 130 moves is the direction in which the crimping wall 132 approaches the connecting member 140. As the crimping wall 132 gradually approaches the connecting member 140, the wire is clamped between the connecting member 140 and the crimping wall 132, completing the wiring of the power strip.

[0082] It can be seen that the wiring terminal 100 of the above structure is simple in structure and the wiring operation is relatively convenient.

[0083] like Figure 3 As shown, in some embodiments, a plurality of fasteners 260 are provided, and insulating isolation ribs 270 are provided between the plurality of fasteners 260, and / or a countersunk platform 280 is provided on the terminal box 110, and the end of the fastener 260 is located in the countersunk platform 280, and / or a limiting buckle 290 is provided on the terminal box 110, and the end of the fastener 260 is located on the side of the limiting buckle 290 close to the inside of the terminal box 110.

[0084] There are multiple fasteners 260, and the multiple fasteners 260 can be connected to a terminal 130 respectively. The multiple terminals 130 can be connected to wires respectively. The multiple fasteners 260 can also be connected to different positions of the same terminal 130. The multiple fasteners 260 work together to connect one or more wires to the terminal 130.

[0085] The provision of insulating isolation ribs 270 between the plurality of fasteners 260 increases the electrical clearance and creepage distance between different fasteners 260 , making it less likely for short circuits to occur between different fasteners 260 .

[0086] The end of the fastener 260 is located in the sink 280, and the side wall of the sink 280 can limit the position of the fastener 260 to prevent the fastener 260 from shaking in the sink 280. The side wall of the sink 280 can also isolate multiple fasteners 260 to prevent adjacent fasteners 260 from being too close to each other and causing short circuits.

[0087] A limit buckle 290 is provided on the terminal box 110, and the end of the fastener 260 is located on the side of the limit buckle 290 close to the terminal box 110. The limit buckle 290 limits the position of the fastener 260, so that the fastener 260 is not easy to move out of the terminal box 110 and detach from the terminal box 110, and can prevent the ends of multiple fasteners 260 exposed outside the terminal box 110 from being too long and close to each other, thereby preventing a short circuit between the multiple fasteners 260.

[0088] Optionally, the limiting buckles 290 may be evenly distributed at multiple locations around the circumference of the fastener 260 so as to limit the position of the fastener 260 from multiple directions and allow the ends of the fastener 260 to be stressed substantially synchronously.

[0089] Optionally, a side of the limiting buckle 290 away from the fastener 260 is set as a guiding slope, so that when the fastener 260 is connected to the side wall of the terminal box 110, the end of the fastener 260 is conveniently inserted between the limiting buckle 290 and the side wall of the terminal box 110.

[0090] The connection terminal 100 may adopt the above three configuration schemes for the fastener 260 at the same time, or may adopt only one or two configuration schemes for the fastener 260 , and the embodiment of the present application does not limit this.

[0091] According to another aspect of an embodiment of the present application, a power strip is provided. Figure 5 The schematic diagram of the structure of a power strip provided in an embodiment of the present application is as follows. The power strip comprises the connection terminal 100 and the connecting bar 400 in any of the above embodiments, and the connecting bar 400 is connected to the connecting piece 140 of the connection terminal 100 .

[0092] The structure of the connection terminal 100 in this example of the present application can refer to the structure of the connection terminal 100 in any of the above embodiments, and will not be repeated here.

[0093] It can be understood that the power strip further includes a housing 500 , and the connecting strip 400 and the connecting terminal 100 are both disposed in the housing 500 .

[0094] The fixing method of the housing 500 and the terminal block 100 may be: a support column 300 is provided outside the terminal box 110 or the terminal cover 120 of the terminal block 100, an adapting hole is provided on the housing 500, and the support column 300 on the terminal block 100 is installed in the adapting hole, so as to position and install the terminal block 100 and the housing 500. The structure of the support column 300 can be referred to Figure 1 , Figure 2 and Figure 4 .

[0095] Since the power strip in the embodiment of the present application adopts the connection terminal 100 in the above-mentioned subject embodiment, the power strip in the embodiment of the present application is also beneficial to improving the versatility of the connecting strip 400 in power strips of different specifications, and facilitating the automated production of the power strip.

[0096] In summary, the present application provides a terminal block 100 including a connector 140, and enables the connector 140 to be connected to the connecting strip 400 outside the terminal box 110. This allows for the production of power strips of different specifications by only changing the shape and position of the connector 140 so that the connector 140 can adapt to the power strips of corresponding specifications, while the connecting strip 400 does not need to be replaced. This enables the connecting strip 400 to be used in power strips of various specifications, which is beneficial to the automated production of power strips and improves the production efficiency of the power strips.
