Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electrical accessories, and in particular to a switch terminal assembly and a socket strip. Background Art
[0002] A power strip with a switch is a type of power strip. There is usually a switch button on the power strip. Users can disconnect the circuit inside the power strip by pressing the switch button without unplugging the power plug of the power strip, which makes it safer and more convenient to use.
[0003] A power strip with a switch usually includes a cover, a bottom shell, a socket assembly, a wiring terminal, a switch assembly, and a connecting strip, wherein the switch assembly includes a stationary contact piece, a moving contact piece, and a push assembly that drives the moving contact piece to contact or move away from the stationary contact piece. When assembling the power strip, it is usually necessary to directly assemble the wiring terminal and the switch assembly together and install them in the bottom shell as a whole.
[0004] When producing power strips with switches, the wiring terminals and switch components are usually assembled separately on different production lines and then assembled together, which results in low production efficiency and high cost. Utility Model Content
[0005] In view of the above problems, an embodiment of the present application provides a switch terminal assembly and a power strip, which can improve the production efficiency of the power strip and reduce the production cost.
[0006] According to one aspect of an embodiment of the present application, a switch terminal assembly is provided, which is used for a power strip, and the switch terminal assembly includes a shell, a terminal, a static contact, a moving contact and a pushing assembly; wherein the shell is provided with a terminal cavity and a switch cavity; the terminal is provided in the terminal cavity for connecting the wire; the static contact is partially located in the terminal cavity and contacts with the terminal, and is partially located in the switch cavity; the moving contact is partially located in the switch cavity for contacting with the static contact, and is partially located outside the shell for connecting the connecting strip in the power strip; the pushing assembly is connected to the shell, and is at least partially located in the switch cavity for pushing the moving contact to contact with the static contact.
[0007] The terminal is used to connect the wires. At the same time, when the power strip is assembled, the terminal is connected to the main circuit of the power strip. The static contact piece contacts the terminal. After the terminal is energized, the terminal and the static contact piece are electrically connected. After the moving contact piece is electrically connected to the connecting strip, under the action of the pushing component, when the moving contact piece contacts the static contact piece, the moving contact piece and the static contact piece are electrically connected, so that the main circuit of the power strip is connected. When the moving contact piece and the static contact piece are separated, the main circuit of the power strip is disconnected.
[0008] It can be seen that the switch terminal assembly combines the structure with the wiring function and the structure with the switch function. When assembling the switch terminal assembly, it is only necessary to assemble the above-mentioned components according to the structure in the present application. There is no need to assemble the separate wiring terminal and the switch assembly separately and then assemble the two together. This simplifies the assembly process of the power strip, improves the production efficiency of the power strip, and reduces the production cost of the power strip.
[0009] In some embodiments, the pushing component has a trigger end, which abuts against the moving contact piece. The moving contact piece is provided with a positioning portion, which cooperates with the trigger end to limit the contact position between the trigger end and the moving contact piece.
[0010] By adopting the above solution, the trigger end can be relatively fixedly abutted against the moving contact piece, preventing the moving contact piece from slipping relative to the trigger end, resulting in failure of normal contact and separation between the moving contact piece and the stationary contact piece, thereby improving the reliability of the switch terminal assembly.
[0011] In some embodiments, the switch terminal assembly further includes a connector, one end of which is located in the terminal cavity and the other end of which is located outside the housing, for connecting to a connecting strip in the power strip.
[0012] By adopting the above scheme, the connection strip is connected to one end of the connector outside the housing, so that the connection strip and the switch terminal assembly 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 corresponding specifications, and the connection strip does not need to be replaced. Therefore, it can be used universally in power strips of various specifications. Moreover, after such a setting, the switch terminal assembly can be pre-assembled, and then the switch terminal assembly as a whole can be assembled with the connection strip. In this way, even in power strips of different specifications, the connection method of the connection strip and the switch terminal assembly is unified, which is conducive to the automated production of the power strip and can improve the production efficiency of the power strip.
[0013] In some embodiments, an insulating isolation rib is provided between the moving contact piece and the connecting member.
[0014] After setting the isolation ribs, the straight-line distance between the static contact and the connector can be reduced as much as possible, but the electrical clearance and creepage distance between the static contact and the connector can meet the requirements, so that short circuit is not likely to occur between the static contact and the connector, and the volume of the switch terminal assembly can be further reduced.
[0015] In some embodiments, a first positioning groove is provided on the shell, and the connecting member is partially located in the first positioning groove.
[0016] By adopting the above scheme, the first positioning groove can locate the position of the connecting piece, so that the part of the connecting piece located outside the shell will not swing at will, so that during the assembly process of the switch terminal assembly and the connecting strip, the connecting piece and the connecting strip can be well aligned and the two can be reliably connected.
[0017] In some embodiments, a positioning protrusion is provided on the connecting member, and the positioning protrusion abuts against one end of the side wall of the first positioning groove to limit the position of the connecting member in the first positioning groove.
[0018] The provision of the positioning protrusion makes the position of the portion of the connecting piece in the first positioning groove more fixed, so that the length and shape of the portion of the connecting piece located on both sides of the first positioning groove are more fixed, which facilitates the automated production of the switch terminal assembly, and further facilitates the assembly between the switch terminal assembly and other components of the strip, which is beneficial to improving the reliability and uniformity of the quality of the strip.
[0019] In some embodiments, the shell includes a first outer wall, and one end of the connecting piece used to connect to the connecting strip and one end of the static contact piece used to connect to the connecting strip both protrude from the first outer wall; a second positioning groove is provided on the first outer wall, and the second positioning groove is used to position the connecting strip so that the distance between the connecting strip and the connecting piece or the connecting strip and the static contact piece is less than a preset distance.
[0020] By adopting the above scheme, when assembling the switch terminal assembly and the connecting strip, the connecting strip is clamped in the second positioning groove. Under the positioning of the second positioning groove, the distance between the connecting strip and the connecting piece or the static contact piece is less than the preset distance, thereby facilitating the connection of the connecting strip to the connecting piece or the static contact piece, and facilitating fixing the connecting strip during the connection process.
[0021] In some embodiments, the shell includes a base and an upper cover that are interlocked with each other, and the upper cover is provided with supporting ribs, which press the connecting piece.
[0022] By adopting the above solution, the supporting ribs can support and position the connector during the assembly process of the power strip, and can also support the connector during the subsequent use of the power strip, so that the internal structure of the power strip is more stable.
[0023] In some embodiments, a positioning support column is provided on the outer wall of the shell. When the switch terminal assembly is assembled to the shell of the power strip, the positioning support column is used to cooperate with the positioning hole in the shell.
[0024] This is beneficial for achieving rapid positioning and assembly between the switch terminal assembly and the housing of the power strip.
[0025] According to another aspect of an embodiment of the present application, a power strip is provided, comprising the switch terminal assembly in any of the above embodiments.
[0026] The embodiment of the present application combines a structure with a wiring function and a structure with a switch function in a switch terminal assembly. When assembling the switch terminal assembly, it is only necessary to assemble the above-mentioned components according to the structure of the present application. There is no need to assemble the separate wiring terminals and the switch assembly separately and then assemble the two together. This simplifies the assembly process of the power strip, improves the production efficiency of the power strip, and reduces the production cost of the power strip.

[0044] 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.

[0045] An embodiment of the present application provides a switch terminal assembly 1000, which is used for a power strip.
[0046] Please refer to Figure 1 and Figure 2The switch terminal assembly 1000 includes a shell 110, a terminal 120, a static contact piece 130, a movable contact piece 140 and a pushing assembly 150; wherein the shell 110 is provided with a terminal cavity 111 and a switch cavity 112; the terminal 120 is arranged in the terminal cavity 111 for connecting the wire; the static contact piece 130 is partially located in the terminal cavity 111 and contacts with the terminal 120, and is partially located in the switch cavity 112; the movable contact piece 140 is partially located in the switch cavity 112 for contacting with the static contact piece 130, and is partially located outside the shell 110 for connecting the connecting strip in the power strip; the pushing assembly 150 is connected to the shell 110, and is at least partially located in the switch cavity 112 for pushing the movable contact piece 140 to contact with the static contact piece 130.
[0047] The shell 110 is made of insulating material and can be composed of one part or multiple parts. For example, the shell 110 includes a base 113 and an upper cover 114. The base 113 and the upper cover 114 are snap-fitted to form a terminal cavity 111 and a switch cavity 112 therebetween. Before assembling the base 113 and the upper cover 114, personnel can install the terminal 120, the static contact piece 130 and the moving contact piece 140 into corresponding positions in the terminal cavity 111 and the switch cavity 112, and then assemble the base 113 and the upper cover 114 to complete the assembly of the shell 110.
[0048] The terminal 120 is a metal part, and one terminal 120 may have only one wire installation position or multiple wire installation positions, and the multiple wire installation positions are insulated from each other. For example, three wire installation positions are arranged in a row on the terminal 120, which are used to install the neutral wire, the live wire, and the ground wire respectively. When the switch terminal assembly 1000 is assembled to the power strip, the three wire installation positions can be directly or indirectly connected to a connecting strip respectively.
[0049] It is understandable that when a plurality of wire installation positions are provided on the terminal 120 , at least one wire installation position is sequentially connected to the connection bar through the stationary contact piece 130 and the movable contact piece 140 .
[0050] The static contact piece 130 contacts the terminal 120. When the terminal 120 is energized, the terminal 120 is electrically connected to the static contact piece 130. After the moving contact piece 140 is electrically connected to the connecting strip, under the action of the pushing component 150, when the moving contact piece 140 contacts the static contact piece 130, the moving contact piece 140 and the static contact piece 130 are electrically connected, so that the main circuit of the power strip is connected. When the moving contact piece 140 is separated from the static contact piece 130, the main circuit of the power strip is disconnected.
[0051] The structure of the pushing component 150 is the same as or similar to the pushing component 150 in any type of switch structure in the related art, and the embodiment of the present application does not limit this.
[0052] Optionally, the pushing assembly 150 at least partially protrudes from the shell 110 , and when the switch terminal assembly 1000 is assembled to the power strip, one end of the pushing assembly 150 protruding from the shell 110 is exposed to the outside of the shell of the power strip to facilitate the user to operate the pushing assembly 150 .
[0053] It can be seen that the switch terminal assembly 1000 of the above structure combines the structure with the structure with the switch function. When assembling the switch terminal assembly 1000, it is only necessary to assemble the above components according to the structure in the present application. There is no need to assemble the separate wiring terminals and switch assemblies separately and then assemble the two together. This simplifies the assembly process of the power strip, improves the production efficiency of the power strip, and reduces the production cost of the power strip.
[0054] Please refer to Figure 3 and Figure 4 In some embodiments, the pushing component 150 has a trigger end 151, which abuts against the moving contact piece 140. The moving contact piece 140 is provided with a positioning portion 141, which cooperates with the trigger end 151 to limit the contact position between the trigger end 151 and the moving contact piece 140.
[0055] The moving contact piece 140 can be a metal sheet structure, and the moving contact piece 140 has a certain elasticity, so that the pushing component 150 only needs to apply force to the moving contact piece 140 in a one-way stroke, and does not need to apply force to the moving contact piece 140 in the other direction of the stroke. The moving contact piece 140 can return to its original position under the action of the elastic force.
[0056] For example, the movable contact piece 140 is a bent spring piece. When the trigger end 151 of the pushing component 150 is pushed out, force can be applied to the movable contact piece 140 to intensify the bending of the movable contact piece 140, so that the movable contact piece 140 contacts the stationary contact piece 130. At the same time, the movable contact piece 140 accumulates a certain elastic potential energy. When the trigger end 151 of the pushing component 150 is retracted, the movable contact piece 140 restores its original bent shape under the action of the elastic force, thereby separating from the stationary contact piece 130.
[0057] The positioning portion 141 on the movable contact piece 140 can be a groove structure or a protrusion structure. When the positioning portion 141 is a groove structure, the trigger end 151 can abut against the groove, and when the positioning portion 141 is a protrusion structure, the trigger end 151 can be provided with a groove structure, and the groove structure is sleeved on the protrusion structure.
[0058] Exemplarily, the push assembly 150 includes a spring, and the trigger end 151 is one end of the spring. When the positioning portion 141 is a groove structure, the end of the spring is against the groove structure, and when the positioning portion 141 is a protrusion structure, the end of the spring is sleeved on the protrusion structure. It can be seen that even if the push assembly 150 remains unchanged, the structure of the positioning portion 141 can be various, as long as the trigger end 151 can be positioned.
[0059] By adopting the above scheme, the trigger end 151 can be relatively fixedly abutted against a specific position on the moving contact piece 140, preventing the moving contact piece 140 from slipping relative to the trigger end 151, resulting in the moving contact piece 140 and the static contact piece 130 being unable to contact and separate normally, thereby improving the reliability of the switch terminal assembly 1000.
[0060] Please continue to refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the switch terminal assembly 1000 further includes a connector 160 , one end of which is located in the terminal cavity 111 , and the other end of which is located outside the housing 110 , for connecting to a connecting strip in the power strip.
[0061] In the related art, the switch terminal assembly does not include a connector, and the connecting strip is manufactured separately from the switch terminal assembly, and the two are finally assembled when the power strip is assembled. During assembly, since the structures of the switch terminal assemblies 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 switch terminal assembly, which makes the connecting strip unable to be universal and unable to be automatically produced.
[0062] The switch terminal assembly 1000 in the present application is provided with a connector 160. Thus, when the switch terminal assembly 1000 is installed in a power strip, the connecting strip in the power strip does not need to be bent into a shape that is compatible with the internal structure of the switch terminal assembly 1000 to be connected to the switch terminal assembly 1000. Instead, the connecting strip is connected to the end of the connecting piece 160 extending out of the housing 110 to achieve electrical connection between the connecting strip and the switch terminal assembly 1000.
[0063] When producing power strips of different specifications, only the shape and position of the connecting member 160 need to be changed so that the connecting member 160 can adapt to the power strip of the corresponding specifications, and the connecting strip does not need to be replaced. Therefore, it can be used universally in power strips of various specifications.
[0064] In addition, after such configuration, the switch terminal assembly 1000 can be pre-assembled, and then the switch terminal assembly 1000 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 switch terminal assembly 1000 is unified, which is conducive to the automated production of the power strips and can improve the production efficiency of the power strips.
[0065] For example, three wire installation positions are provided on the terminal 120, the stationary contact piece 130 is installed at one of the wire installation positions, and the other two wire installation positions are respectively installed with the connector 160, and the connector 160 and the movable contact piece 140 extend from the same surface of the housing 110. When assembling the terminal block 120 assembly and the connecting strip, a connecting strip is connected to each of the two connectors 160 and one movable contact piece 140, and the connection position of the connector 160 and the connecting strip is the end of the connector 160 extending outside the housing 110, and the end of the movable contact piece 140 connected to the connecting strip is the end of the movable contact piece 140 extending from the housing 110.
[0066] Optionally, the three wire installation positions on the terminal 120 are arranged in a row, and the distances between the three wire installation positions are equal, so that it is convenient for users to connect the wires.
[0067] like Figure 4 As shown, in some embodiments, an insulating isolation rib 170 is provided between the movable contact piece 140 and the connecting member 160 .
[0068] An isolation rib 170 is provided so that the straight-line distance between the moving contact piece 140 and the connecting piece 160 can be reduced as much as possible while the electrical clearance and creepage distance between the moving contact piece 140 and the connecting piece 160 meet the requirements, so that a short circuit is less likely to occur between the moving contact piece 140 and the connecting piece 160, and the volume of the switch terminal assembly 1000 can be further reduced.
[0069] It can be understood that the isolation rib 170 can be set only at a position where the moving contact piece 140 and the connecting piece 160 are close to each other, or the isolation rib 170 can be set in the entire area between the moving contact piece 140 and the connecting piece 160 along the length direction of the moving contact piece 140 or the connecting piece 160. The embodiment of the present application is not limited to this.
[0070] like Figure 4 As shown, in some embodiments, a first positioning groove 180 is provided on the housing 110 , and a portion of the connecting member 160 is located in the first positioning groove 180 .
[0071] The first positioning groove 180 can be a groove-like structure formed by directly grooved on the outer wall of the shell 110, or it can be a groove-like structure on a component set on the outer wall of the shell 110 with multiple protrusions set on the outer wall of the shell 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 shell 110.
[0072] In addition, the number of the first positioning grooves 180 can be one or more. Multiple first positioning grooves 180 can position the connecting member 160 from different bending sections of the connecting member 160, or can position the connecting member 160 at different positions of the same bending section of the connecting member 160. The embodiments of the present application are not limited to this.
[0073] The first positioning groove 180 can position the connector 160 so that the portion of the connector 160 outside the housing 110 will not swing at will, thereby allowing the connector 160 and the connecting strip to be well aligned and reliably connected during assembly of the switch terminal assembly 1000 and the connecting strip.
[0074] Please continue to refer to Figure 4 In some embodiments, a positioning protrusion 161 is provided on the connecting member 160 , and the positioning protrusion 161 abuts against one end of the side wall of the first positioning groove 180 to limit the position of the connecting member 160 in the first positioning groove 180 .
[0075] Exemplarily, the length direction of the first positioning groove 180 is the first direction, the connecting member 160 passes through the first positioning groove 180 along the first direction, and the positioning protrusion 161 is located at one end of the first positioning groove 180 along the first direction and abuts against one end of the side wall of the first positioning groove 180.
[0076] The provision of the positioning protrusion 161 makes the position of the portion of the connector 160 in the first positioning groove 180 more fixed, so that the length and shape of the portion of the connector 160 located on both sides of the first positioning groove 180 are more fixed, which facilitates the automated production of the switch terminal assembly 1000, and further facilitates the assembly between the switch terminal assembly 1000 and other components of the power strip, which is beneficial to improving the reliability and uniformity of the power strip quality.
[0077] Please refer to Figure 4 In some embodiments, the shell 110 includes a first outer wall 190, and one end of the connecting member 160 used to connect to the connecting strip and one end of the static contact piece 130 used to connect to the connecting strip both protrude from the first outer wall 190; a second positioning groove 200 is provided on the first outer wall 190, and the second positioning groove 200 is used to position the connecting strip so that the distance between the connecting strip and the connecting member 160 or the connecting strip and the static contact piece 130 is less than a preset distance.
[0078] The shape and structure of the second positioning groove 200 are the same as or similar to those of the first positioning groove 180 , and will not be described in detail in the embodiment of the present application.
[0079] The preset distance is a distance that can ensure a reliable connection between the connecting strip and the connecting member 160. For example, when the distance between the connecting member 160 and the connecting strip is less than 2 mm, the connecting member 160 and the connecting strip are close to each other, which makes it convenient to connect the connecting strip and the connecting member 160 together by welding. The preset distance is 2 mm, or any value less than 2 mm.
[0080] When assembling the switch terminal assembly 1000 and the connecting strip, the connecting strip is clamped in the second positioning groove 200. Under the positioning of the second positioning groove 200, the distance between the connecting strip and the connecting piece 160 or the static contact piece 130 is less than the preset distance, thereby facilitating the connection of the connecting strip to the connecting piece 160 or the connecting strip to the static contact piece 130, and facilitating fixing the connecting strip during the connection process.
[0081] like Figure 1 As shown, in some embodiments, the housing 110 includes a base 113 and an upper cover 114 that are interlocked with each other. The upper cover 114 is provided with a supporting rib 115 , and the supporting rib 115 presses against the connecting piece 160 .
[0082] Optionally, the base 113 and the upper cover 114 can be fixed in a simple manner, for example, a snap hole is set on one of the base 113 and the upper cover 114, and a snap platform is set on the other, and the snap platform is set in the snap hole to limit the separation of the base 113 and the upper cover 114.
[0083] By adopting the above solution, the support ribs 115 can not only support and position the connector 160 during the assembly process of the power strip, but also support the connector 160 during the subsequent use of the power strip, so that the internal structure of the power strip is more stable.
[0084] Optionally, combined Figure 2 and Figure 6 In the case where the shell 110 includes a base 113 and an upper cover 114 that are interlocked, an opening is provided on the side of the base 113 close to the upper cover 114, a first limiting protrusion 220 is provided on the inner wall of the base 113, and a second limiting protrusion 230 is provided on the outer wall of the terminal 120, and the first limiting protrusion 220 is located on the side of the second limiting protrusion 230 close to the opening of the base 113.
[0085] When assembling the switch terminal assembly 1000, after the terminal 120 is installed into the terminal cavity 111 from the opening side of the base 113, the second limiting protrusion 230 is blocked by the first limiting protrusion 220, so that the terminal 120 is not easy to escape from the opening of the base 113, which is conducive to further assembling the base 113 and the terminal 120 with other components.
[0086] After the switch terminal assembly 1000 is assembled, since the opening of the base 113 is closed by the upper cover 114, the upper cover 114 mainly serves to limit the position of the terminal 120 in the terminal cavity 111, and the first limiting protrusion 220 and the second limiting protrusion 230 can prevent the terminal 120 from falling out of the opening of the base 113 when the upper cover 114 is loose or damaged.
[0087] It can be understood that when the first limiting protrusion 220 and the second limiting protrusion 230 are provided, since the first limiting protrusion 220 and the second limiting protrusion 230 partially replace the function of the upper cover 114, the switch terminal assembly 1000 may not include the upper cover 114, thereby simplifying the structure of the switch terminal assembly 1000 and reducing the volume and weight of the switch terminal assembly 1000.
[0088] In other words, when the switch terminal assembly 1000 includes the upper cover 114, the first limiting protrusion 220 and the second limiting protrusion 230 may or may not be provided; when the switch terminal assembly 1000 does not include the upper cover 114, the switch terminal assembly 1000 must include the above-mentioned structure of the first limiting protrusion 220 and the second limiting protrusion 230.
[0089] Optionally, a side of the first limiting protrusion 220 close to the opening of the base 113 is set as an inclined surface, and / or a side of the second limiting protrusion 230 away from the opening of the base 113 is set as an inclined surface.
[0090] During the process of inserting the terminal 120 from the opening of the base 113, the first limiting protrusion 220 and the second limiting protrusion 230 may contact each other through at least one inclined surface, which may be located on the first limiting protrusion 220, or on the second limiting protrusion 230, or the surfaces contacted by the first limiting protrusion 220 and the second limiting protrusion 230 may both be inclined surfaces. After contact, the first limiting protrusion 220 and the second limiting protrusion 230 squeeze each other, so that the side wall of the base 113 and / or the side wall of the terminal 120 gradually produce elastic deformation, which is conducive to the installation of the terminal 120 into the base 113. After the first limiting protrusion 220 and the second limiting protrusion 230 are out of contact, the side wall of the base 113 and / or the side wall of the terminal 120 return to their original shape, the terminal 120 is installed in place, the first limiting protrusion 220 and the second limiting protrusion 230 limit each other, and the terminal 120 is not easy to fall out of the opening of the base 113.
[0091] like Figure 1 As shown, in some embodiments, a positioning support column 210 is provided on the outer wall of the housing 110. When the switch terminal assembly 1000 is assembled to the housing of the power strip, the positioning support column 210 is used to cooperate with the positioning hole in the housing. This arrangement is conducive to achieving rapid positioning and assembly between the switch terminal assembly 1000 and the housing of the power strip.
[0092] The switch terminal assembly 1000 disclosed in the present application may have multiple ways of connecting a wire to the switch terminal assembly 1000 .
[0093] like Figure 5 and Figure 6As shown, in some embodiments, the switch terminal assembly 1000 also includes a fastener 240, which is connected to the side wall of the housing 110, and one end of the fastener 240 is located in the terminal cavity 111 and is threadedly connected to the terminal 120. The fastener 240 can rotate to drive the terminal 120 to move, and the movement of the terminal 120 drives the wire inserted into the terminal 120 to move so that the wire contacts the connector 160 or the static contact piece 130.
[0094] The fastener 240 can be a screw or a similar part of a screw. Taking the fastener 240 as a screw as an example, the screw is rotatably connected to the side wall of the shell 110 and can be axially rotated relative to the side wall of the shell 110, while the screw is fixed axially relative to the terminal 120 box. The stud part of the screw passes through the side wall of the shell 110 and is located in the terminal cavity 111, and the stud part is threadedly connected to the terminal 120.
[0095] For example, please refer to Figure 6 The terminal 120 may include a connecting wall 121, a crimping wall 122, and an intermediate wall 123 disposed between the connecting wall 121 and the crimping wall 122. The fastener 240 is threadedly connected to the connecting wall 121. The connecting member 160 is inserted between the connecting wall 121 and the crimping wall 122 and is located directly opposite to the fastener 240, so that the connecting member 160 and the fastener 240 are mutually limited. When connecting a wire, the wire is inserted between the connecting wall 121 and the crimping wall 122, and then the fastener 240 is rotated so that the fastener 240 drives the terminal 120 to move. The direction of movement of the terminal 120 is the direction in which the crimping wall 122 approaches the connecting member 160. As the crimping wall 122 gradually approaches the connecting member 160, the wire is clamped between the connecting member 160 and the crimping wall 122, completing the wiring of the power strip.
[0096] It can be seen that the switch terminal assembly 1000 of the above structure is simple in structure and the wiring operation is relatively convenient.
[0097] like Figure 5 and Figure 6 As shown, in some embodiments, a plurality of fasteners 240 are provided, and insulating barrier ribs 250 are provided between the plurality of fasteners 240, and / or a sink 260 is provided on the shell 110, and the end of the fastener 240 is located inside the sink 260, and / or a limiting buckle 270 is provided on the shell 110, and the end of the fastener 240 is located on the side of the limiting buckle 270 close to the inside of the shell 110.
[0098] There are multiple fasteners 240, and the multiple fasteners 240 can be connected to a terminal 120 respectively. The multiple terminals 120 can be connected to wires respectively. The multiple fasteners 240 can also be connected to different positions of the same terminal 120. The multiple fasteners 240 work together to connect one or more wires to the terminal 120.
[0099] The insulating barrier ribs 250 are arranged between the plurality of fasteners 240 , so that the electrical clearance and creepage distance between different fasteners 240 are increased, and short circuits between different fasteners 240 are less likely to occur.
[0100] The end of the fastener 240 is located in the sink 260, and the side wall of the sink 260 can limit the position of the fastener 240 to prevent the fastener 240 from shaking in the sink 260. The side wall of the sink 260 can also isolate multiple fasteners 240 to prevent adjacent fasteners 240 from being too close to each other and causing short circuits.
[0101] A limiting buckle 270 is provided on the shell 110, and the end of the fastener 240 is located on the side of the limiting buckle 270 close to the shell 110. The limiting buckle 270 limits the position of the fastener 240, so that the fastener 240 is not easy to move outside the shell 110 and detach from the shell 110, and can prevent the ends of multiple fasteners 240 exposed outside the shell 110 from being too long and close to each other, thereby preventing a short circuit between the multiple fasteners 240.
[0102] Optionally, the limiting buckles 270 may be evenly distributed at multiple locations around the circumference of the fastener 240 so as to limit the position of the fastener 240 from multiple directions and allow the ends of the fastener 240 to be stressed substantially synchronously.
[0103] Optionally, a side of the limiting buckle 270 away from the fastener 240 is set as a guiding slope, so that when the fastener 240 is connected to the side wall of the shell 110, the end of the fastener 240 is conveniently inserted between the limiting buckle 270 and the side wall of the shell 110.
[0104] The switch terminal assembly 1000 may adopt the above three configuration schemes for the fastener 240 at the same time, or may adopt only one or two configuration schemes for the fastener 240 , and the embodiment of the present application does not impose any limitation on this.
[0105] According to another aspect of an embodiment of the present application, a power strip is provided, comprising the switch terminal assembly 1000 in any one of the above embodiments.
[0106] The structure of the switch terminal assembly 1000 in this embodiment of the present application may refer to the structure of the switch terminal assembly 1000 in any of the above embodiments, and will not be repeated here.
[0107] It can be understood that the power strip further includes a housing, and the connecting strip and the switch terminal assembly 1000 are both disposed inside the housing.
[0108] Since the power strip in the embodiment of the present application adopts the switch terminal assembly 1000 in the above-mentioned subject embodiment, the power strip in the embodiment of the present application also has the effect of simplifying the assembly process of the power strip, improving the production efficiency of the power strip, and reducing the production cost of the power strip.
[0109] In summary, the embodiment of the present application combines a structure with a wiring function and a structure with a switch function in the switch terminal assembly 1000. When assembling the switch terminal assembly 1000, it is only necessary to assemble the above-mentioned components according to the structure in the present application. There is no need to assemble the separate wiring terminal 120 and the switch assembly separately and then assemble the two together. This simplifies the assembly process of the power strip, improves the production efficiency of the power strip, and reduces the production cost of the power strip.
