[0031] like Figure 1A , 1BThe embodiments of this application provide electrical connection terminals (100A, 100B, 200A, 200B) for mains power. Mains power can be understood as alternating current (AC), with an effective voltage between 100V and 240V, such as 100V, 110V, 120V, 220V, and 230V. The electrical connection terminals (100A, 100B, 200A, 200B) for mains power will be referred to as electrical connection terminals (100A, 100B, 200A, 200B) below. These electrical connection terminals (100A, 100B, 200A, 200B) can be used in electrical appliances, such as lamps.

[0032] In some embodiments, the electrical connection terminals (100A, 100B) can be female terminals (100A, 100B), and the electrical connection terminals (200A, 200B) can be male terminals (200A, 200B). In some embodiments, combined with Figure 9A , Figure 9B , Figure 9C The electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B) can be plugged in and detached. In other embodiments, combined with Figure 10 Electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B) are connected by wires. In other embodiments, combined with Figure 11 Electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B) are directly connected.

[0033] For example, the electrical connection terminals (100A, 100B) have a structure that accommodates at least a portion of other terminals, such as male terminals (200A, 200B), in combination with Figure 9A , Figure 9B , Figure 9C When at least a portion of the structure of the electrical connection terminals (200A, 200B) is accommodated within the accommodating space of the electrical connection terminals (100A, 100B), that is, when at least a portion of the electrical connection terminals (200A, 200B) is inserted into the electrical connection terminals (100A, 100B), the electrical connection terminals (200A, 200B) and the electrical connection terminals (100A, 100B) achieve both physical and electrical connection. Figure 9A , Figure 9B , Figure 9CThis diagram illustrates the physical and electrical connections between electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B). It should be noted that these electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B) can be separated after being physically and electrically connected. Figure 9D , Figure 9D The diagram illustrates the separated state of electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B). In this embodiment, the electrical connection terminals (200A, 200B) and electrical connection terminals (100A, 100B) can rotate relative to each other during and after insertion.

[0034] like Figure 1A , 1B 1C, 1D, 1E, 1F, 1G, 1H, 1I, the electrical connection terminal 100A includes a first electrode 110A, a second electrode 120, and a female connector 130. For example... Figure 2A , 2B 2C, Electrical connection terminal 100B includes a first electrode 110B, a second electrode 120, and a female connector 130. The second electrode 120 and female connector 130 of electrical connection terminal 100A have the same structure as the second electrode 120 and female connector 130 of electrical connection terminal 100B. In other optional embodiments, the second electrode 120 and female connector 130 of electrical connection terminal 100A have different structures than the second electrode 120 and female connector 130 of electrical connection terminal 100B. Electrical connection terminals (100A, 100B) have a first axis P1, and the first electrode 110A, second electrode 120, and female connector 130 of electrical connection terminals (100A, 100B) can rotate together around the first axis P1.

[0035] For example, both the first electrode (110A, 110B) and the second electrode 120 are made of conductive material. When the electrical connection terminals (100A, 100B) are energized, the first electrode (110A, 110B) can act as one electrode, and the second electrode 120 can act as another electrode, for example, the first electrode (110A, 110B) can act as the negative electrode, and the second electrode 120 can act as the positive electrode.

[0036] For example, the female connector 130 serves as a carrier for the first electrode (110A, 110B) and the second electrode 120, and the female connector 130 is made of insulating material.

[0037] like Figure 1C , 1D1E, 1F, 1G, 1H, the female connector 130 includes a carrier 132 and a spacer 131 disposed at one end of the carrier 132. Exemplarily, the carrier 132 and the spacer 131 are integrally formed, for example, by plastic injection molding. In other optional embodiments, the carrier 132 and the spacer 131 are fixedly connected together, for example, by a physical connection, including but not limited to adhesive connection and threaded connection.

[0038] The spacer 131 and the support 132 together define a groove 133. The support 132 has a through hole 1321 that penetrates the support 132 along the first axis P1. The through hole 1321 communicates with the groove 133, and the spacer 1321 surrounds the through hole 131, with the hole wall of the through hole 1321 spaced apart from the spacer 131. The edges of the spacer 131 and the support 132 are spaced apart.

[0039] like Figure 1A , 1B 1C, 1D, 1E, 1F, 1G, 1H, 1I, the first electrode (110A, 100B) includes a first part (111A, 111B). The first part (111A, 111B) of the first electrode (110A, 100B) is disposed on the outside of the spacer 131 and surrounds the spacer 131. The outer surface of the spacer 131 and the first electrode (110A, 100B) including the first part (111A, 111B) are spaced apart to define a first spacer space 101. The first part of the first electrode (110A, 100B) can undergo elastic deformation to change the size of the first spacer space 101. Figure 1D and Figure 2C The diagram illustrates the state of the first part (111A, 111B) before it undergoes elastic deformation, which is called the initial state. Figure 1E The diagram illustrates the state of the first part 111A after elastic deformation, referred to as the deformation state; wherein, the first part 111A is in the second position X2 after elastic deformation from the first position X1. The first position X1 can be understood as the initial position, and the second position X2 can be understood as the deformation position.

[0040] like Figure 1A , 1B1C, 1D, 1E, 1F, 1G, 1H, 1I, 2A, 2B, 2C, the second electrode 120 includes a first part 121, the first part 121 of the second electrode 120 is disposed inside the spacer 131, and the first part 121 of the second electrode 120 is located in the groove 133, the spacer 131 is disposed around the first part 121 of the second electrode 120, the spacer 131 completely confines the first part 121 of the second electrode 120 within the spacer 131, the inner surface of the spacer 131 is spaced apart from the first part 121 of the second electrode 120 to define the second spacer space 102.

[0041] The spacer 131 separates the first electrode (110A, 100B), including the first portion (111A, 111B), from the first portion 121 of the second electrode 120.

[0042] Among them, the female seat 130, the first electrode (110A, 110B) and the second electrode 120 can rotate together around the same axis, namely the first axis P1.

[0043] The first electrode (110A, 110B) also includes a second part (112A, 112B) and a third part (113A, 113B). The first part (111A, 111B), the second part (112A, 112B) and the third part (113A, 113B) of the first electrode (110A, 110B) are connected in sequence. The second electrode 120 also includes a second part 122 and a third part 123. The first part 121, the second part 122 and the third part 123 of the second electrode 120 are connected in sequence. The second portions (112A, 112B) of the first electrode elements (110A, 110B) are disposed on the carrier 132, and the second portion 122 of the second electrode element 120 is disposed on the carrier 132, wherein the second portions (112A, 112B) of the first electrode elements (110A, 110B) and the second portion 122 of the second electrode element 120 are insulated from each other on the carrier 132. The third portions (113A, 113B) of the first electrode elements (110A, 110B) are disposed outside the carrier 132, and the third portion 123 of the second electrode element 120 is disposed outside the carrier 132, wherein the third portions (113A, 113B) of the first electrode elements (110A, 110B) and the third portion 123 of the second electrode element 120 are insulated from each other.

[0044] For example, the second portions (112A, 112B) of the first electrode members (110A, 110B) are disposed on the outer surface of the carrier 132. For example, the outer surface of the carrier 132 is provided with at least one platform 1322, and the second portions (112A, 112B) of the first electrode members (110A, 110B) are disposed on the platform 1322. For example, the second portion 122 of the second electrode member 120 is disposed within the through hole 1321.

[0045] For example, the electrical connection terminals (100A, 100B) further include a limiting member 140, which includes a first limiting body 141 and a second limiting body 142, which are integrally disposed. The first limiting body 141 is connected to the carrier 132 and is disposed outside the first portion (111A, 111B) of the first electrode (110A, 110B). The first limiting body 141 can limit the radial movement of the first portion (111A, 111B) of the first electrode (110A, 110B) along the electrical connection terminals (100A, 100B). A portion of the first limiting body 141 is disposed on the outer side of the carrier 132, and the first limiting body 141 covers the second part (112A, 112B) of the first electrode (110A, 110B), and the first limiting body 141 and the second part (112A, 112B) of the first electrode (110A, 110B) abut against each other.

[0046] For example, the second limiting body 142 is disposed at the end of the first limiting body 141 away from the carrier 132. The first portion (111A, 111B) of the first electrode (110A, 110B) away from the carrier 132 is restricted within the second limiting body 142. The second limiting body 142 can restrict the first portion (111A, 111B) of the first electrode (110A, 110B) from moving axially along the electrical connection terminals (100A, 100B). The axial direction of the electrical connection terminals (100A, 100B) can be understood as the direction of the first axis P1 of the electrical connection terminals (100A, 100B). The second limiting body 142 is disposed radially from the spacer 131 along the electrical connection terminals (100A, 100B). The limiting member 140 in this embodiment can limit the range of motion of the first part (111A, 111B) of the first electrode (110A, 110B), while the limiting member 140 can increase the strength of the first part (111A, 111B) of the first electrode (110A, 110B).

[0047] In one optional embodiment, the limiting member 140 is made of a conductive material, and a portion of the first limiting body 141 is sleeved on the outer surface of the carrier 132 and connected to the carrier 132. In another optional embodiment, the limiting member 140 is made of an insulating material, and a portion of the first limiting body 141 is connected to the outer surface of the carrier 132, or the first limiting body 141 and the spacer 131 are disposed at the same end of the carrier 132. When the limiting member 140 is also made of an insulating material, the limiting member 140 and the carrier 132 can be integrally formed, for example, by plastic injection molding. It should be noted that it is also feasible for the limiting member 140 and the carrier 132 to be non-integral, for example, by using threaded connection, adhesive layer connection, etc.

[0048] For example, in the initial state, the first portion (111A, 111B) of the first electrode (110A, 110B) and the spacer 131 are spaced apart by a distance L1 along the radial direction of the electrical connection terminals (100A, 100B). In other words, in the initial state, the first portion (111A, 111B) of the first electrode (110A, 110B) is spaced apart by a distance L1 along the radial direction of the electrical connection terminals (100A, 100B). The width of the second space 102 along the radial direction of the electrical connection terminals (100A, 100B) is L2, the distance between the second limiting body 142 and the spacer 131 along the radial direction of the electrical connection terminals (100A, 100B) is L3, and the thickness of the spacer 131 along the radial direction of the electrical connection terminals (100A, 100B) is H1.

[0049] For example, H1 ≥ 0.5 mm.

[0050] For example, L2 ≥ 1 mm.

[0051] For example, L2≥L1≥H1.

[0052] For example, L3 > L1. This ensures that other terminals, such as male terminals (200A, 200B), can be inserted into the first spacer space 101 and the second spacer space 102 through the opening 103 of the electrical connection terminals (100A, 100B). It should be noted that the opening 103 of the electrical connection terminals (100A, 100B) can be understood as the opening 103 of the first spacer space 101 and the second spacer space 102.

[0053] For example, the first portion 121 of the second electrical connector 120 has a cylindrical structure.

[0054] For example, the female base 130, the first electrode (110A, 110B), the second electrode 120 and the limiting member 140 can rotate together around the same axis, namely the first axis P1.

[0055] For example, the first portion 111A of the first electrode 110A includes an abutment portion 115A and a mounting portion 114A connected to each other. The abutment portion 115A is capable of elastic deformation. In the initial state, at least a portion of the abutment portion 115A is closer to the spacer 131 than the mounting portion 114A. Similarly, the initial state of the abutment portion 115A can be understood as the initial state of the first portion 111A, which will not be described further here.

[0056] In one alternative embodiment, both ends of the abutment portion 115A are connected to the mounting portion 114A. Exemplarily, the abutment portion 115A is arched.

[0057] In another alternative embodiment, one end of the abutment portion 115B is connected to the mounting portion 114B, while the other end of the abutment portion 115B is separated from the mounting portion 114B. For example, the other end of the abutment portion 115B is located away from the opening 103 of the electrical connection terminal 100B. For example, the abutment portion 115B includes a first deformable structure 1151, a second deformable structure 1152, and a third deformable structure 1153 connected in sequence. All three structures are capable of deformation, and the first and third deformable structures are bent relative to the second deformable structure 1152. The second deformable structure 1152 is closer to the spacer 131 than both the first and third deformable structures 1151 and 1153. During the process of inserting other terminals, such as male terminals (200A, 200B), into electrical connection terminal 100B, one of the electrical connectors of male terminals (200A, 200B) will preferentially abut against the second deformation structure 1152, and continue to connect male terminals (200A, 200B) and electrical connection terminal 100B. The male terminals (200A, 200B) drive the second deformation structure 1152 to deform preferentially, thereby driving the first deformation structure 1151 and the third deformation structure 1153 to deform, thereby changing the space of the first gap space 101.

[0058] The first electrode components (110A, 110B) further include a plurality of through holes (1141A, 1141B) formed on the mounting portions (114A, 114B), with the plurality of through holes (1141A, 1141B) spaced apart. In one optional embodiment, a through hole 1141A is formed between two adjacent abutment portions 115A. The hole wall 1142A forming the through hole 1141A can be part of the abutment portion 115A. In another optional embodiment, the two ends of the abutment portion 115A are directly connected to the inner surface 1143A of the mounting portion 114A.

[0059] In one alternative embodiment, the abutment portion 115B and the through hole 1141B are positioned correspondingly, and the abutment portion 115B is connected to the hole wall 1142B forming the through hole 1141B. One or both ends of the abutment portion 115B are connected to the hole wall 1142B. In another alternative embodiment, one end of the abutment portion 115B is connected to the inner surface 1143B of the mounting portion 114B.

[0060] In one alternative embodiment, the mounting portion 114A is disposed around the spacer 131. In another alternative embodiment, the mounting portion 114B includes an opening 1144B formed on its side, which saves material on the mounting portion 114B.

[0061] In actual testing, it was found that if the first electrode (110A, 110B) and the second electrode 120 are not separated by the spacer 131, the second electrode 120 will be directly surrounded by the first electrode (110A, 110B). That is, the second electrode 120 is located on the inner wall of the first electrode (110A, 110B), with no physical isolation between them, only air between them, posing a risk of mutual contact. On the other hand, since the first part (111A, 111B) of the first electrode (110A, 110B) can undergo elastic deformation, and this part of the elastically deformable part is designed to bulge inward toward the second electrode 120, the first part (111A, 111B) is at risk of falling off or loosening due to deformation, which could lead to contact between the first electrode (110A, 110B) and the second electrode 120, resulting in a short circuit. Based on this, the embodiments of this application design at least one spacer, such as spacer 131, between the two electrode components to separate them, thus physically isolating the two electrode components. This directly prevents contact between the two electrode components due to deformation, loosening, or detachment, thereby avoiding short circuits. Furthermore, in the embodiments of this application, the first portion (111A, 111B) of the first electrode component (110A, 110B) is enclosed by the limiting member 140, and the first portion 121 of the second electrode component 120 is completely located within the spacer 131. This ensures that the first portion (111A, 111B) of the first electrode component (110A, 110B) and the first portion 121 of the second electrode component 120 are not exposed. Gold fingers cannot touch the first electrode component (110A, 110B) and the second electrode component 120 from the opening 103 of the electrical connection terminals (100A, 100B), making it applicable to AC mains power and complying with electrical safety regulations. It should be noted that when the limiting member 140 is made of a conductive material such as metal, an insulating connector is also provided on the outside of the electrical connection terminals (100A, 100B). The component including the connector and the electrical connection terminals (100A, 100B) is called an electrical connection device, which will be described exemplarily below with reference to other accompanying drawings.

[0062] like Figure 5A , 5B Types 6A, 6B, 6C, 7A, 7B, 7C, 8A, 8B, and 8C, and electrical connection devices (1000A, 1000B, 1000C, 1000D) include electrical connection terminals 100 and connectors 1100. Connectors 1100 are made of insulating material, such as plastic. Connectors 1100 cover the outer surface of the electrical connection terminal 100 and one end face of the electrical connection terminal 100, allowing the open end of the electrical connection terminal 100 to be exposed. The electrical connection terminal 100 can be either electrical connection terminal 100A or electrical connection terminal 100B.

[0063] The connector 1100 may include a connector body 1110 and a sleeve 1120. The sleeve 1120 is disposed on the first end face 1111 of the connector body 1110, for example, the sleeve 1120 and the first end face 1111 of the connector body 1110 are integrally disposed. The outer surface 1113 of the connector body 1110 is provided with an external thread 1114, which is used to connect with the internal thread at the opening of the lampshade. The female connector 130, the first electrode (110A, 110B) and the second electrode 120 of the electrical connector terminal 100 are all disposed on the connector body 1110 and protrude from the first end face 1111. The sleeve 1120 is disposed around the female connector 130, the first electrode (110A, 110B) and the second electrode 120 of the electrical connector terminal 100, and the first electrode (110A, 110B) and the second electrode 120 are confined within the sleeve 1120. Thus, a portion of the electrical connection terminal 100 is disposed within the connection body 1110, and one end of the electrical connection terminal 100 is wrapped by the connection body 1110. The outer side of the portion of the electrical connection terminal 100 not disposed within the connection body 1110 is wrapped by the sleeve 1120. Other terminals, such as male terminals (200A, 200B), can be inserted into the electrical connection terminal 100 from the end of the sleeve 1120 away from the connection body 1110.

[0064] Electrical connection terminal 100 and connector 1100 can rotate together around the same axis, namely the third axis P3. That is, female connector 130, first electrode (110A, 110B), second electrode 120 and connector 1100 can rotate together around the same axis, namely the third axis P3. The third axis P3 and the first axis P1 are coaxial.

[0065] In practical applications, before the female terminals (100A, 100B) and male terminals (200A, 200B) of this embodiment are plugged in, the female terminals (100A, 100B) are first electrically connected to the electrical plug. The connector 1100 of this embodiment ensures that the electrical connection terminals 100 do not come into contact with the first electrical connector (110A, 110B) during the gold finger detection process, thus meeting the requirements for devices using AC mains power, such as lighting fixtures. In some cases, the male terminals (200A, 200B) do not need to be covered by connectors like connector 1100, which facilitates the insertion of the male terminals (200A, 200B) into the female terminals (100A, 100B).

[0066] For example, such as Figure 1A , 1B 1C, 1D, 1E and Figure 2BAs shown, a groove 143 is provided on the outer side of the first limiting body 141. The outer side of the first limiting body 141 can be surrounded and connected by the connecting body 1110. A part of the connecting body 1110 can be placed in the groove 143, thereby increasing the connection strength between the first limiting body 141 and the connecting body 1110.

[0067] like Figure 6A , 6B The electrical connection devices (1000B, 1000C, 1000D) also include mounting bodies (1130B, 1130C, 1130D), which are directly or indirectly connected to the second end face 1112 of the connecting body 1110. The mounting bodies (1130B, 1130C, 1130D) are used to install the electrical connection devices (1000B, 1000C, 1000D) at a predetermined location, which may be a wall, ceiling, or similar location. This application embodiment does not limit the predetermined location for installing the electrical connection devices (1000B, 1000C, 1000D).

[0068] For example, the mounting bodies (1130B, 1130C, 1130D) are made of insulating material and can be integrally formed with the connecting body 1110, such as by integral molding of plastic.

[0069] For example, the mounting bodies (1130B, 1130C, 1130D) are connected to the center of the connecting body 1110.

[0070] In one alternative embodiment, the mounting body 1130B includes a hook 1131B and an mounting space 1132B and an opening 1133B defined by the hook 1131B.

[0071] In another alternative embodiment, the mounting body 1130D includes a mounting ring 1131D and a mounting space 1132D defined by the mounting ring 1131D.

[0072] In another optional embodiment, the mounting body 1130C includes a mounting structure 1134C, a first mounting portion 1131C, a second mounting portion 1132C, and a third mounting portion 1133C. The first mounting portion 1131C and the second mounting portion 1132C are arranged along a first direction F1, and the third mounting portion 1133C is arranged along a second direction F2 with the first mounting portion 1131C and / or the second mounting portion 1132C. The first direction F1 and the second direction F2 are perpendicular. One end of the third mounting portion 1133C away from the first mounting portion 1131C and / or the second mounting portion 1132C is directly or indirectly connected to the second end face 1112. The mounting structure 1134C is arranged along the second direction F2 with the first mounting portion 1131C and / or the second mounting portion 1132C, and the mounting structure 1134C and the third mounting portion 1133C are disposed opposite to each other. The mounting structure 1134C, together with the first mounting portion 1131C and / or the second mounting portion 1132C, defines a mounting hole; or the mounting structure 1134C, together with the first mounting portion 1131C and / or the second mounting portion 1132C, defines a mounting space and an opening; or the mounting structure 1134C defines a mounting hole 1135C on its own; or the mounting structure 1134C defines a mounting space and an opening on its own.

[0073] For example, the mounting body 1130C includes at least one inclined surface 1136C located on the third mounting portion 1133C, such that the size of the portion of the third mounting portion 1133C with the inclined surface 1136C is varied, for example, the size of the third mounting portion 1133C gradually increases from the end away from the first mounting portion 1131C and / or the second mounting portion 1132C toward the end closer to the first mounting portion 1131C and / or the second mounting portion 1132C.

[0074] For example, the third portion (113A, 113B) of the first electrode (110A, 110B) and the third portion 123 of the second electrode 120 in the electrical connection terminal 100 are electrically connected to the wire 1200. For example, the wire 1200 passes through the connecting body 1110 and is electrically connected to the third portion (113A, 113B) of the first electrode (110A, 110B) and the third portion 123 of the second electrode 120. The wire 1200 extends from the second end face 1112 of the connecting body 1110. It is understood that the wire 1200 may include at least two metal wires and an insulating sleeve wrapped around the metal wires. The other end of the wire 1200 can be electrically connected to an electrical plug. The second end face 1112 of the connecting body 1110 is opposite to the first end face 1111.

[0075] The number of wires 1200 can be one or at least two. For example, Figure 5A and5B The diagram shows a wire with a diameter of 1200.

[0076] For example, Figure 6A , 6B Figures 6C, 8A, 8B, and 8C illustrate two wires 1200, namely a first wire 1210 and a second wire 1220. In one scenario, one of the first wire 1210 and the second wire 1220 can be connected to an electrical plug, while the other can be connected to the electrical connection terminal of another electrical connection device. In another scenario, both the first wire 1210 and the second wire 1220 can be connected to the electrical connection terminal of another electrical connection device. For example, the first wire 1210 and the second wire 1220 are located on opposite sides of the mounting body (1130B, 1130D).

[0077] For example, Figure 7A , 7B Figure 7C illustrates three wires 1200: a first wire 1210, a second wire 1220, and a third wire 1230. The third wire 1230 is directly electrically connected to the electrical connection terminal 100, and a portion of the third wire 1230 is located between the connecting body 1110 and the third mounting portion 1133C. The first wire 1210 is electrically connected to both the second wire 1220 and the third wire 1230. The second wire 1220 can be electrically connected to the electrical connection terminals of other electrical connection devices, and the first wire 1210 can be electrically connected to an electrical plug. The connection points of the first wire 1210 with the second wire 1220 and the third wire 1230 are enclosed by the mounting body 1130C. The first wire 1210 is located outside the first mounting portion 1131C, and the second wire 1220 is located outside the second mounting portion 1132C. Exemplarily, the third wire 1230 is located at the center of the connecting body 1110.

[0078] like Figure 3A , 3B 3C, 3D, 3E, 3F, the electrical connection terminal 200A includes a third electrode 210, a fourth electrode 220A, and a male connector 230. For example... Figure 4A , 4B4C and 4D, electrical connection terminal 200B includes a third electrode 210, a fourth electrode 220B, and a male connector 230. The third electrode 210 and male connector 230 of electrical connection terminal 200A have the same structure as those of electrical connection terminal 200B. In other alternative embodiments, the third electrode 210 and male connector 230 of electrical connection terminal 200A have different structures than those of electrical connection terminal 200B. The electrical connection terminals (200A, 200B) have a second axis P2, and the third electrode 210, fourth electrode (220A, 220B), and male connector 230 of the electrical connection terminals (200A, 200B) can rotate together about the second axis P2.

[0079] For example, both the third electrode 210 and the fourth electrode (220A, 220B) are made of conductive material. When the electrical connection terminals (200A, 200B) are energized, the third electrode 210 can act as one electrode and the fourth electrode (220A, 220B) can act as another electrode, for example, the third electrode 210 as the negative electrode and the fourth electrode (220A, 220B) as the positive electrode.

[0080] For example, the male connector 230 serves as a carrier for the third electrode 210 and the fourth electrode (220A, 220B), and the male connector 230 is made of insulating material.

[0081] like Figure 3C , 3DThe male seat component 230 includes an outer spacer 231 and an inner spacer 233. The outer spacer 231 surrounds the inner spacer 233, and the outer spacer 231 and the inner spacer 233 are spaced apart to define a first groove 234. The male seat component 230 also includes a support body 232, with the outer spacer 231 and the inner spacer 233 located at the same end of the support body 232. For example, the support body 232, the outer spacer 231, and the inner spacer 233 are integrally formed, such as by plastic injection molding. It should be noted that the first groove 234 is jointly defined by the support body 232, the outer spacer 231, and the inner spacer 233. The inner spacer 233 and the support body 232 together define a second groove 235. When the male terminals (200A, 200B) and female terminals (100A, 100B) are connected, the third electrode 210 of the male terminals (200A, 200B) is inserted into the first spacer space 101, the fourth electrode (220A, 220B) is inserted into the second spacer space 102, the spacer body 131 of the female terminals (100A, 100B) is inserted into the first groove 234, and the second electrode 120 of the female terminals (100A, 100B) is inserted into the second groove 235. For example, the dimensions of the first groove 234 and the spacer body 131 are adapted to each other.

[0082] like Figure 3A , 3B The third electrode component 210 includes a first part 211, which is disposed on the outer spacer 131 and connected to it. The third electrode component 210 also includes a second part 212 and a third part 213. The second part 212 is disposed on the carrier 232 and connected to it. The third part 213 is disposed on the outside of the carrier 232. The first part 211, the second part 212, and the third part 213 are connected sequentially, for example, as a single unit.

[0083] like Figure 3A , 3BThe male seat components (200A, 200B) also include a third groove 236, which is disposed on the outer side of the support body 232 and the outer side of the outer spacer 231. The male seat components (200A, 200B) also include a first limiting structure 2311 and a second limiting structure 2324. The first limiting structure 2311 is located on the outer side of the outer spacer 231 away from the support body 232, and the second limiting structure 2324 is located on the outer side of the support body 232 away from the outer spacer 231. The third groove 236 is located between the first limiting structure 2311 and the second limiting structure 2324. A portion of the first part 211 and a portion of the second part 212 of the third electrode component 210 are disposed within the third groove 236, and both ends are limited by the first limiting structure 2311 and the second limiting structure 2324. In one optional embodiment, the outer surface of the portion of the third electrode 210 disposed within the third groove 236 is flush with the outer surfaces of the first limiting structure 2311 and the second limiting structure 2324. In other optional embodiments, the outer surface of the portion of the third electrode 210 disposed within the third groove 236 may be concave or convex compared to the outer surfaces of the first limiting structure 2311 and the second limiting structure 2324.

[0084] For example, the male seat components (200A, 200B) further include a fourth groove 2323, which is formed on the outer side of the support body 232 and is located near the second limiting structure 2324. The fourth groove 2323 communicates with the third groove 236. The third electrode component 210 also includes a protrusion 214, which is disposed on the inner side of the second portion 212 of the third electrode component 210. The protrusion 214 is disposed in the fourth groove 2323 and can connect with the groove wall forming the fourth groove 2323 to increase the stability of the third electrode component 210 connected to the support body 231 and the outer spacer 231.

[0085] For example, the outer side of the carrier 232 is provided with at least one platform 2322, and a portion of the second part 212 of the third electrode 210 is disposed on the platform 2322.

[0086] For example, the fourth electrode (220A, 220B) includes a first portion (221A, 221B) disposed within the inner spacer 233. The fourth electrode (220A, 220B) defines a insertion space (2214A, 2214B) for accommodating a second electrode 120 of other terminals such as female terminals (100A, 100B). The first portion (221A, 221B) of the fourth electrode (220A, 220B) is capable of elastic deformation within the inner spacer 233 to change the size of the insertion space (2214A, 2214B). Figure 3D and Figure 4B The diagram illustrates the state of the first part (221A, 221B) before it undergoes elastic deformation, which is called the initial state. Figure 4C The diagram illustrates the state of the first part 221B after elastic deformation, referred to as the deformation state; wherein, the first part 211B, after undergoing elastic deformation from the first position Y1, is at the second position Y2. The first position Y1 can be understood as the initial position, and the second position Y2 can be understood as the deformation position.

[0087] For example, the fourth electrode (220A, 220B) further includes a second part (222A, 222B) and a third part (223A, 223B). The first part (221A, 221B), the second part (222A, 222B) and the third part (223A, 223B) of the fourth electrode (220A, 220B) are connected in sequence. The second part (222A, 222B) of the fourth electrode (220A, 220B) is disposed inside the carrier 232, and the third part (223A, 223B) of the fourth electrode (220A, 220B) is disposed outside the carrier 232. For example, the carrier 232 is provided with a through hole 2321, which penetrates the carrier 232 along the second axis P2 direction. The through hole 2321 is connected to the second groove 235. The through hole 2321 is surrounded by an inner spacer 233, and the hole wall forming the through hole 2321 is spaced apart from or connected to the inner spacer 233.

[0088] For example, the first portion 211A of the fourth electrode 220A includes at least two electrode pieces, such as a first electrode piece 2211A and a second electrode piece 2212A, which are spaced apart by a insertion space 2214A. For example, the first electrode piece 2211A and the second electrode piece 2212A are arranged opposite to each other. The distance between the first electrode piece 2211A and the second electrode piece 2212A is variable. For example, the distance between the first electrode piece 2211A and the second electrode piece 2212A gradually increases and then gradually decreases from one end of the opening 203 of the electrical connection terminal 200A toward the other end, so as to facilitate the insertion of the second electrode 120 in other electrical connection terminals such as female terminals (100A, 100B) into the insertion space 2214. In this embodiment, the inner spacer 233 also has at least two fifth grooves 237, which are connected to the second groove 235. The number of fifth grooves 237 is the same as the number of electrode pieces (2211A, 2212A). For example, there are two fifth grooves 237, and one fifth groove 237 can accommodate one electrode piece (2211A, 2212A). The first electrode piece 2211A and the second electrode piece 2212A can undergo elastic deformation in the second groove 235 and the fifth groove 237. Specifically, during the mutual insertion of other terminals such as female terminals (100A, 100B) and male terminals (200A, 200B), the second electrode 120 is inserted into the insertion space 2214A, driving the electrode pieces (2211A, 2212A) to undergo elastic deformation. The opening 203 can be understood as the opening of the first groove 234 and the opening of the second groove 235.

[0089] For example, the first portion 221B of the fourth electrode 220B includes a mounting portion 225B and an abutting portion 224B. The abutting portion 224B is capable of elastic deformation. In its initial state, at least a portion of the abutting portion 224B is spaced apart from the inner surface of the inner spacer 233. Similarly, the initial state of the abutting portion 224B can be understood as the initial state of the first portion 221B, which will not be described further here.

[0090] In one optional embodiment, the abutment portion 224B and the mounting portion 225B are connected. Exemplarily, the abutment portion 224B is arched. In another optional embodiment, one end of the abutment portion 224B is connected to the mounting portion 225B, and the other end of the abutment portion 224B is separately disposed from the mounting portion 225B. For a more detailed structure, please refer to [reference needed]. Figure 2A , Figure 2B and Figure 2C This will not be elaborated upon here.

[0091] For example, the fourth electrode 220B further includes a plurality of through holes 2241B, which are spaced apart. In one optional embodiment, a through hole 2241B is formed between two adjacent abutment portions 224B. The hole wall 2242B forming the through hole 2241B can be part of the abutment portion 224B. In another optional embodiment, the two ends of the abutment portion 224B are directly connected to the inner surface 2243B of the mounting portion 225B; the specific structure can be found in [reference needed]. Figure 2A , Figure 2B and Figure 2C This will not be elaborated upon here.

[0092] Among them, the male seat 230, the third electrode 210 and the fourth electrode (220A, 220B) can rotate around the same axis, namely the second axis P2.

[0093] In this embodiment, the inner spacer 233 and the outer spacer 231 can completely separate the first part 211 of the third electrode 210 and the first part (221A, 221B) of the fourth electrode (220A, 220B). Furthermore, the first groove 234 formed between the inner spacer 233 and the outer spacer 231 can accommodate the spacer in the female terminals (100A, 100B). Therefore, after the male terminals (200A, 200B) and the female terminals (100A, 100B) are plugged into each other, the first electrode (110A, 110B) and the third electrode 210 are electrically connected, and the second electrode 120 and the fourth electrode (220A, 220B) are electrically connected. Moreover, the first electrode (110A, 110B) and the third electrode 210 are at least separated from the second electrode 120 and the fourth electrode (220A, 220B) by spacer 131, inner spacer 233 and outer spacer 231, thereby ensuring that there is sufficient physical isolation between the different electrodes after the male terminals (200A, 200B) and the female terminals (100A, 100B) are plugged in, ensuring safety performance.

[0094] like Figure 9A , 9BThe present application provides a terminal assembly (300A, 300B, 300C, 300D) for mains power, denoted as 9C, 9D, 9E, 9F, 9G, 9H, 9I, 9J, 9K, 9L, 10, 11, and 12. This terminal assembly (300A, 300B, 300C, 300D) can be used in electrical appliances, such as lighting fixtures. The terminal assembly (300A, 300B, 300C, 300D) includes a female terminal 100 and a male terminal 200. The female terminal 100 can refer to either the female terminal 100A or 100B mentioned above, and the male terminal 200 can refer to either the male terminal 200A or male terminal 200B mentioned above. For example, Figure 9E and 9F The schematic terminal assembly includes a female terminal 100A and a male terminal 100B; Figure 9G and Figure 9H The schematic terminal assembly includes a female terminal 100A and a male terminal 200B; Figure 9I and Figure 9J The schematic terminal assembly includes a female terminal 100B and a male terminal 200A; Figure 9K and Figure 9L The schematic terminal assembly includes a female terminal 100B and a male terminal 200B. The specific structures of the female terminal 100B and the male terminal 200B will not be described in detail in this embodiment.

[0095] Some embodiments, such as Figure 9A , 9B For terminals 9C, 9D, 9E, 9F, 9G, 9H, 9I, 9J, 9K, and 9L, the male terminal 200 and female terminal 100 of terminal assembly 300A can be plugged in and disconnected. Figure 9A , 9B The symbols 9C, 9E, 9F, 9G, 9H, 9I, 9J, 9K, and 9L indicate the connection status of male terminal 200 and female terminal 100. Figure 9D This illustrates the state where the male terminal 200 and the female terminal 100 are separated.

[0096] After the male terminal 200 and the female terminal 100 are plugged in, the first part 211 of the third electrode 210 and the outer spacer 231 are located in the first space 101, and the first part 211 of the third electrode 210 is in contact with the abutting part (115A, 115B) of the first electrode (100A, 100B). The first part (221A, 221B) of the fourth electrode (220A, 220B) and the inner spacer 233 are located in the second space 102. The first part 121 of the second electrode 120 is located in the plugging space (2214A, 2214B) of the fourth electrode (220A, 220B), and the first part 121 of the second electrode 120 is in contact with the first part (221A, 221B) of the fourth electrode (220A, 220B), thus realizing the electrical connection between the male terminal 200 and the female terminal 100.

[0097] During or after the insertion of the male terminal 200 and the female terminal 100, the male terminal 200 and the female terminal 100 can rotate relative to each other, for example, the male terminal 200 and the female terminal 100 can rotate around the fourth axis P4. Furthermore, at least an inner spacer 233, an outer spacer 231, and a spacer 131 of the female connector 130 are spaced apart from the first part 211 of the third electrode 210 and the first part (110A, 110B) of the first electrode (100A, 100B) and the first part 121 of the second electrode 120 and the first part (221A, 221B) of the fourth electrode (220A, 220B).

[0098] During or after the male terminal 200 and female terminal 100 are connected, the first part 211 of the third electrode 210 will press the first part (110A, 110B) of the first electrode (100A, 100B) to cause elastic deformation of the first part (110A, 110B) of the first electrode (100A, 100B), thereby ensuring that the two are in close contact; and the first part 121 of the second electrode 120 will press the first part (221A, 221B) of the fourth electrode (220A, 220B) to cause elastic deformation of the first part (221A, 221B) of the fourth electrode (220A, 220B), thereby ensuring that the two are in close contact.

[0099] For example, the outer surface of the outer electrode of the female terminal 100 is discontinuous, while the outer surface of the outer electrode of the male terminal 200 is continuous, for example, the outer surface of the outer electrode of the male terminal 200 has a smooth transition. It should be noted that the female terminal 100 is electrically connected to the plug before the male terminal. To ensure the user's electrical safety, an insulating connector 1100 is provided on the outer side of the female terminal 100. The outer surface of the outer electrode of the female terminal 100, such as the first electrode (110A, 110B), is discontinuous, which facilitates connection with the connector 1100.

[0100] Other embodiments, such as Figure 10 The male terminal 200 and female terminal 100 of the terminal assembly 300B are connected by a wire 340, which separates the male terminal 200 and female terminal 100. The male terminal 200, female terminal 100, and wire 340 can rotate together around a fifth axis P5. The terminal assembly 300B may also include a first connecting body 310A, a second terminal body 310B, a first external thread 330A, a second external thread 330B, a first sleeve 320A, and a second sleeve 320B. The female terminal 100 is disposed within the first sleeve 320A and the first connecting body 310A, and the first external thread 330A is disposed on the outer surface of the first connecting body 310A. The male terminal 200 is disposed within the second sleeve 320B and the second connecting body 310B, and the second external thread 330B is disposed on the outer surface of the second connecting body 310B. Figure 10 The male terminal 200 shown is used for mating with other female terminals, and Figure 10 The female terminal shown is used for mating with other male terminals. It should be noted that there is a gap between the second sleeve 320B and the male terminal 200, and the second sleeve 320B can be fitted onto the other female terminal during the mating process of the male terminal 200 with other female terminals.

[0101] Other embodiments, such as Figure 11 The male terminal 200 and female terminal 100 of the terminal assembly 300C are directly connected, and the male terminal 200 and female terminal 100 can rotate together around the sixth axis P6. The terminal assembly 300C may further include a first connecting body 310C, a second terminal body 310D, a first external thread 330C, a second external thread 330D, a first sleeve 320C, and a second sleeve 320D. The female terminal 100 is disposed within the first sleeve 320C and the first connecting body 310C, and the first external thread 330C is disposed on the outer surface of the first connecting body 310C. The male terminal 200 is disposed within the second sleeve 320D and the second connecting body 310D, and the second external thread 330D is disposed on the outer surface of the second connecting body 310D. Figure 11 The male terminal 200 shown is used for mating with other female terminals, and Figure 11The female terminal shown is used for mating with other male terminals. It should be noted that there is a gap between the second sleeve 320D and the male terminal 200, and the second sleeve 320D can be fitted onto the other female terminal during the mating process of the male terminal 200 with other female terminals.

[0102] Other embodiments, such as Figure 12 , Figure 12 The terminal assembly 300D shown is... Figure 10 The difference in the terminal assembly 300B shown is that the male terminal 200 is directly connected to the second connecting body 310B, and its outer side is not covered by a second body. Similarly, Figure 12 The male terminal 200 and female terminal 100 shown can rotate together around the seventh axis P7.

[0103] like Figure 13 and Figure 14 This application also provides an electrical connector (600A, 600B), which includes an electrical plug (640A, 640B), a wire (650A, 650B), and a female terminal 100. The female terminal 100 can refer to either female terminal 100A or female terminal 100B, and will not be described in detail here. The electrical plug 640A is physically and electrically connected to the female terminal 100 through the wire 650A, and the electrical plug 640B is physically and electrically connected to the female terminal 100 through the wire 650B. The structures of the electrical plug 640A and the electrical plug 640B are different. For example, the pins of the electrical plug 640A are roughly cylindrical, while the pins of the electrical plug 640B are roughly cuboid. For example, the electrical connectors (600A, 600B) may further include a connecting body (610A, 610B), a sleeve (620A, 620B), and an external thread (630A, 630B). A female terminal 100 is disposed within the connecting body (610A, 610B) and the sleeve (620A, 620B), and the external thread (630A, 630B) is disposed on the outer surface of the connecting body (610A, 610B). The connecting body (610A, 610B), the sleeve (620A, 620B), and the external thread (630A, 630B) can be referenced from the above description and will not be repeated here.

[0104] Figure 15A , 15B16, 17, 18A, 18B, 18C, 18D, 19, 20, 21A, 21B, 22, 23, 24A, 24B, 24C, 24D, 25, 26 and 27. This application also provides a light-emitting body (400A, 400B, 400C, 400D, 400E, 400F, 400G, 400H, 400I, 400J, 400K, 400L, 400M, abbreviated as 400A-M) for mains power. The light-emitting body (400A-M) will be referred to as light-emitting body (400A-M) in the following text. The light-emitting body (400A-M) can be applied to light-emitting electrical appliances, such as lamps.

[0105] An alternative embodiment, such as Figure 15A , 15B 16, 17, 18A, 18B, 18C, 18D, 19, 20, and 27, the light-emitting elements (400A, 400B, 400C, 400D, 400E, 400F, 400M) include one or more light-emitting elements 440, a male terminal 410, and a rigid circuit board (430A, 430B, 430C, 430D, 430E, 430F, 430M). The rigid circuit board (430A, 430B, 430C, 430M) is electrically connected to one or more light-emitting elements 440 to control the one or more light-emitting elements 440 to emit light, and the one or more light-emitting elements 440 can be LED light-emitting elements. Male terminal 410 is rigidly fixed to the rigid circuit board (430A, 430B, 430C, 430M) and electrically connected to it. This male terminal 410 can be referenced to male terminal 200A or male terminal 200B as described above; the specific structure of male terminal 410 will not be repeated here. After male terminal 410 and the rigid circuit board (430A, 430B, 430C, 430M) are fixedly connected, both male terminal 410 and the rigid circuit board (430A, 430B, 430C, 430M) can rotate together around the eighth axis P8. This male terminal 410 can be plugged into any of the above female terminals, such as female terminal 100A or female terminal 100B.

[0106] Another alternative embodiment, such as Figure 21A , 21BItems 22, 23, 24A, 24B, 24C, 24D, 25, and 26, and light-emitting elements (400G, 400H, 400I, 400J, 400K, 400L), include one or more light-emitting elements 440, a male terminal 410, a female terminal 420, and a rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L). The rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L) is electrically connected to one or more light-emitting elements 440 to control the light emission of one or more light-emitting elements 440, which can be LED light-emitting elements. The male terminal 410 and the female terminal are fixed to the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L) as if rigidly fixed, and the male terminal 410 and the female terminal are electrically connected to the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L). The male terminal 410 can refer to the male terminal 200A or male terminal 200B as described above, and the female terminal 100 can refer to the female terminal 100A or female terminal 100B as described above. The specific structure of the male terminal 410 and the female terminal 420 will not be described in detail here. After the male terminal 410 and female terminal 420 are fixedly connected to the rigid circuit boards (430G, 430H, 430I, 430J, 430K, 430L), the male terminal 410, female terminal 420, and rigid circuit boards (430G, 430H, 430I, 430J, 430K, 430L) can rotate together around the ninth axis P9. The male terminal 410 can be plugged into other female terminals such as female terminal 100A or female terminal 100B, and the female terminal 420 can be plugged into other male terminals such as male terminal 200A or male terminal 200B.

[0107] For example, the male terminal 410 is disposed at one end of the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L), and the female terminal 420 is disposed at the other end of the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L), with the male terminal 410 and the female terminal 420 positioned opposite each other. It should be noted that the positional relationship between the male terminal 410, the female terminal 420, and the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L) is not limited to this. In other optional embodiments, the male terminal 410 and the female terminal 420 form an angle greater than 0 degrees and less than 180 degrees with respect to the rigid circuit board (430G, 430H, 430I, 430J, 430K, 430L).

[0108] like Figure 24A , 24BIn order to ensure the safety performance of the light-emitting elements (400J, 400K, 400L) during actual installation and application, embodiments of this application further include at least one outer casing (470J, 470K, 470L). The outer casing (470J, 470K, 470L) is arranged around the rigid circuit board (430J, 430K, 430L) to cover at least one light-emitting element 440. The outer casing (470J, 470K, 470L) is light-transmitting, and the light emitted by the light-emitting element 440 covered by the outer casing (470J, 470K, 470L) can pass through the outer casing (470J, 470K, 470L). The outer casing (470J, 470K, 470L) is also arranged around the female terminal 420, and the female terminal 420 is confined within the outer casing (470J, 470K, 470L). Therefore, during the gold finger detection process, the electrode components inside the female terminal 420 cannot be touched.

[0109] For example, the outer casing (470J, 470K, 470L) of the light emitter (400J, 400K, 400L) includes a first casing (471J, 471K, 471L) and a second casing (472J, 472K, 472L), which can be nested together. The second set of bodies (472J, 472K, 472L) covers the female terminal 420, and the inner side of the second set of bodies (472J, 472K, 472L) is spaced apart from the outer side of the female terminal 420; the first set of bodies (471J, 471K, 471L) covers the male terminal 410, and the inner side of the first set of bodies (471J, 471K, 471L) is spaced apart from the outer side of the male terminal 410; during the process of connecting the male terminal 410 and the female terminal 420 to other terminals, at least a portion of the other terminals can be inserted into the first set of bodies (471J, 471K, 471L) and the second set of bodies (472J, 472K, 472L). The first set (471J, 471K, 471L) and the second set (472J, 472K, 472L) together cover the rigid circuit board (430J, 430K, 430L).

[0110] The structure of the first set of bodies (471K, 471L) can be the same as that of the first set of bodies 471J, and the structure of the second set of bodies (472K, 472L) can be the same as that of the second set of bodies 472J. The embodiments of this application are described using the structures of the first set of bodies 471J and the second set of bodies 472J as examples.

[0111] For example, the first housing 471J includes a first housing portion 4711J, a second housing portion 4712J, and a first blocking portion 4713J. The first housing portion 4711J and the second housing portion 4712J are connected and arranged along the ninth axis P9. The first blocking portion 4713J is disposed at the connection position of the first housing portion 4711J and the second housing portion 4712J, and is disposed inside the first housing portion 4711J and the second housing portion 4712J. The second housing portion 4712J is used to housing the male terminal 410. The second housing 472J includes a third housing portion 4721J, a fourth housing portion 4722J, and a second blocking portion 4723J. The third housing portion 4721J and the fourth housing portion 4722J are connected and arranged along the ninth axis P9. The second blocking part 4723J is disposed at the connection position between the third sleeve part 4721J and the fourth sleeve part 4722J, and the second blocking part 4723J is disposed inside the third sleeve part 4721J and the fourth sleeve part 4722J. The fourth sleeve part 4722J is used to sleeve the female terminal 420. The first sleeve part 4711J and the third sleeve part 4721J are both used to sleeve the rigid circuit board 430J.

[0112] The first set of fixtures 4711J defines a first subspace 4731J, and the third set of fixtures 4721J defines a second subspace 4732J. The first subspace 4731J and the second subspace 4732J are connected to form a first space 473J. The first space 473J is used to accommodate a rigid circuit board 430J and one or more light-emitting elements 440. In some optional embodiments, the first space 473J may also accommodate other components such as a flexible circuit board 450 and a support 460. In this embodiment, one or more light-emitting elements 440 are directly disposed on the flexible circuit board 450, the flexible circuit board 450 is mounted on the support 460, and the flexible circuit board 450 and the rigid circuit board 430J are electrically connected. The support 460 can be disposed around the rigid circuit board 430J.

[0113] The second sleeve 4712J defines the connected second space 474J and the first opening 475J. The fourth sleeve 4722J defines the connected third space 477J and the second opening 478J. The first blocking part 4713J defines the first through hole 476J, and the second blocking part 4723J defines the second through hole 479J. The first through hole 476J connects the second space 474J and the first space 473J, and the second through hole 479J connects the third space 477J and the first space 473J. The male terminal 410 is accommodated in the second space 474J and the first through hole 476J. The female terminal is accommodated in the third space 477J and the second space 479J. In actual installation, the male terminal 410 is first inserted from the first sub-space 4731J into the first through hole 476J, and then further inserted into the second space 474J. The first blocking part 4713J is used to prevent the rigid circuit board 430J from entering the second space 474J. Then, the female terminal is inserted from the second sub-space 4732J into the second space 479J, and continues into the third space 477J. The second blocking part 4723J is used to prevent the rigid circuit board 430J from entering the third space 477J. Finally, the first sleeve part 4711J and the third sleeve part 4721J are connected together. It should be noted that it is also feasible to install the female terminal first and then the male terminal. For example, the first sleeve part 4711J is provided with a first connecting structure 4714J, and the third sleeve part 4721J is provided with a second connecting structure 4724J, which are fixedly connected. For example, the connection between the first connecting structure 4714J and the second connecting structure 4724J is smoothly transitioned. The connection methods of the first connecting structure 4714J and the second connecting structure 4724J include, but are not limited to: threaded connection, adhesive layer connection, snap-fit ​​connection, and hot melt connection.

[0114] For example, the diameter of the first sleeve 4711J is larger than the diameter of the second sleeve 4712J.

[0115] For example, the diameter of the third sleeve 4721J is larger than the diameter of the fourth sleeve 4722J.

[0116] For example, the diameter of the first sleeve 4711J is equal to the diameter of the third sleeve 4721J.

[0117] For example, the diameter of the second sleeve 4712J is equal to the diameter of the fourth sleeve 4722J.

[0118] For example, the diameter of the first spacer 4713J is equal to the diameter of the second spacer 4723J.

[0119] In this embodiment, one or more light-emitting elements 440 and the rigid circuit board can be physically connected directly or indirectly.

[0120] One situation, such as Figure 15A , 15B One or more light-emitting elements 440 of the light-emitting bodies (400A, 400D, 400G, 400J) and the rigid circuit board (430A, 430D, 430G, 430J) are indirectly physically connected. One or more light-emitting elements 440 are physically and electrically connected to the rigid circuit board (430A, 430D, 430G, 430J) through the flexible circuit board 450. Specifically, one or more light-emitting elements 440 are disposed on one side of the flexible circuit board 450, and the other side of the flexible circuit board 450 is disposed around the rigid circuit board (430A, 430D, 430G, 430J). The flexible circuit board 450 can be disposed around the peripheral side of the rigid circuit board (430A, 430D, 430G, 430J) to expose at least one end face of the rigid circuit board (430A, 430D, 430G, 430J), which facilitates the electrical connection between the end face of the rigid circuit board (430A, 430D, 430G, 430J) and the male terminal 410. Alternatively, the flexible circuit board 450 may be positioned at least around the peripheral side of the rigid circuit board (430A, 430D, 430G, 430J) without covering at least one end face of the rigid circuit board 430A, to ensure that the male terminal 410 can be electrically connected to the rigid circuit board (430A, 430D, 430G, 430J). The flexible circuit board 450 and the rigid circuit board (430A, 430D, 430G, 430J) can be electrically connected via wires, or the flexible circuit board 450 and the rigid circuit board (430A, 430D, 430G, 430J) can be directly soldered to achieve electrical connection.

[0121] Another situation, such as Figure 16 , 17 As shown in 19, 20, 22, 23, 25, 26 and 27, one or more light-emitting elements 440 of the light-emitting body (400B, 400C, 400E, 400F, 400H, 400I, 400K, 400L, 400M) and the rigid circuit board (430B, 430C, 430E, 430F, 430H, 430I, 430K, 430L, 430M) are directly physically and electrically connected. One or more light-emitting elements 440 are directly disposed on at least one side of the rigid circuit board (430B, 430C, 430E, 430F, 430H, 430I, 430K, 430L, 430M) and are not disposed on the flexible circuit board.

[0122] In one alternative embodiment, such as Figure 27 The rigid circuit board 430M has two sides arranged opposite to each other, and one or more light-emitting elements 440 are disposed on one of the sides of the rigid circuit board 430M.

[0123] In one alternative embodiment, such as Figure 16 , 19 22, 25, The rigid circuit board (430B, 430E, 430H, 430K) has two oppositely arranged sides, and one or more light-emitting elements 440 are disposed on one side of the rigid circuit board (430B, 430E, 430H, 430K), or multiple light-emitting elements 440 are disposed on both sides of the rigid circuit board (430B, 430E, 430H, 430K).

[0124] In one alternative embodiment, such as Figure 17 , 20 23, 26, Rigid circuit boards (430C, 430F, 430I, 430L) have at least two bodies, each body defining two opposite sides. Figure 17 The light-emitting element 400C shown is used as an example for illustrative description. The rigid circuit board 430C includes a first board body 430C1 and a second board body 430C2. The first board body 430C1 has two opposing surfaces, and at least one surface of the first board body 430C1 is provided with one or more light-emitting elements 440. The second board body 430C2 has two opposing surfaces, and at least one surface of the second board body 430C2 is provided with one or more light-emitting elements 440. The first board body 430C1 and the second board body 430C2 are fixedly connected. For example, the first board body 430C1 has a slot structure for inserting the second board body 430C2.

[0125] For example, such as Figure 15A , 15B Models 18A, 18B, 18C, 21A, 21B, 24A, 24B, and 24C, and light emitters (400A, 400D, 400G, 400J), also include a support body 460. A flexible circuit board 450 is mounted on the support body 460, which serves as a carrier for the flexible circuit board 450. The flexible circuit board 450 and the rigid circuit boards (430A, 430D, 430G, 430J) are electrically connected. The support body 460 can be positioned around the rigid circuit board 430J.

[0126] For example, such as Figure 15A and Figure 15BAs shown, the first end 431 and the second end 432 of the rigid circuit board 430A are disposed opposite to each other. The rigid circuit board 430A also includes a first connection structure 433 disposed at the second end 432, and the first connection structure 433 is physically and electrically connected to the male terminal 410. It should be noted that when the second end 432 of the rigid circuit board 430A is connected to the female terminal, the second end 432 of the rigid circuit board 430A can be provided with a second connection structure for physical and electrical connection with the female terminal. Figure 21B As shown, the rigid circuit board 430G includes a first connection structure 431G disposed at one end thereof and a second connection structure 432G disposed at the other end thereof. The first connection structure 431G is physically and electrically connected to the male terminal, and the second connection structure 432G is physically and electrically connected to the female terminal 420.

[0127] For example, such as Figure 15A and Figure 15B As shown, the rigid circuit board 430A also includes a second limiting structure 436 disposed at the first end 431 and a first limiting structure 435 disposed at the second end 432. The first limiting structure 435 and the second limiting structure 436 define a limiting groove 437 on the side of the rigid circuit board 430A. The support body 460 and a part of the flexible circuit board 450 are placed in the limiting groove 437, thereby limiting the support body 460 and the flexible circuit board 450 between the first limiting structure 435 and the second limiting structure 436.

[0128] For example, such as Figure 15A , 15B The male terminals 410 of the light-emitting elements (400A, 400B, 400C, 400D, 400E, 400F, 400G, 400H, 400I, 400J, 400K, 400L) are disposed at the ends of the rigid circuit boards (430A, 430B, 430C, 430D, 430E, 430F, 430G, 430H, 430I, 430J, 430K, 430L). In this embodiment, the rigid circuit board (430A, 430B, 430C, 430D, 430E, 430F, 430G, 430H, 430I, 430J, 430K, 430L) can be connected to one terminal, namely the male terminal 410, or to two terminals, namely the male terminal 410 and the female terminal 420.

[0129] For example, such as Figure 27The male terminal 410 of the light-emitting element 400M is disposed on one side of the rigid circuit board 430M, and one or more light-emitting elements 440 are disposed on the other side of the rigid circuit board 430M. In this embodiment, the rigid circuit board 430M is connected to only one terminal, namely the male terminal 410, and is not connected to the female terminal.

[0130] Other alternative embodiments, such as Figure 18A , 18B In cases where the light-emitting elements (400D, 400E, 400F) include only the male terminal 410 and not the female terminal, the light-emitting elements (400D, 400E, 400F) also include a jacket (470D, 470E, 470F). The jacket (470D, 470E, 470F) is disposed around the rigid circuit board (430D, 430E, 430F) to cover at least one light-emitting element 440. The jacket (470D, 470E, 470F) is light-transmitting, and the light emitted by the light-emitting element 440 covered by the jacket (430D, 430E, 430F) can pass through the jacket (470D, 470E, 470F). The outer casing (470D, 470E, 470F) is also arranged around the male terminal 410, which is confined within the outer casing (470D, 470E, 470F).

[0131] For example, the outer casing (470D, 470E, 470F) of the light emitter (400D, 400E, 400F) includes a first casing (471D, 471E, 471F) and a second casing (472D, 472E, 472F), which can be nested together. The first casing (471D, 471E, 471F) covers the male terminal 410, and the inner surface of the first casing (471D, 471E, 471F) is spaced apart from the outer surface of the male terminal 410; during the insertion process of the male terminal 410 and the female terminal, at least a portion of the female terminal can be inserted into the first casing (471D, 471E, 471F). The first set (471D, 471E, 471F) and the second set (472D, 472E, 472F) together cover the rigid circuit board (430D, 430E, 430F).

[0132] The structure of the first set of bodies (471E, 471F) can be the same as that of the first set of bodies 471D, and the structure of the second set of bodies (472E, 472F) can be the same as that of the second set of bodies 472D. The embodiments of this application are described using the structures of the first set of bodies 471D and the second set of bodies 472D as examples.

[0133] For example, the first housing 471D includes a first housing portion 4711D, a second housing portion 4712D, and a blocking portion 4713D. The first housing portion 4711D and the second housing portion 4712D are connected and arranged along the eighth axis P8. The blocking portion 4713D is disposed at the connection position of the first housing portion 4711D and the second housing portion 4712D, and the first blocking portion 4713D is disposed inside the first housing portion 4711D and the second housing portion 4712D. The second housing portion 4712D is used to housing the male terminal 410. The second housing 472D and the first housing portion 4711D are used together to housing the rigid circuit board 430D.

[0134] The first assembly 4711D and the second assembly 472D together define a first space 473D, which is used to accommodate a rigid circuit board 430D and one or more light-emitting elements 440. In some alternative embodiments, the first space 473D may also accommodate other components such as a flexible circuit board 450 and a support 460. In this embodiment, one or more light-emitting elements 440 are directly disposed on the flexible circuit board 450, which is mounted on the support 460, and the flexible circuit board 450 and the rigid circuit board 430D are electrically connected. The support 460 can be disposed around the rigid circuit board 430D.

[0135] The second sleeve portion 4712D defines a connected second space 474D and an opening 475D. The blocking portion 4713D defines a first through hole 476D. The second sleeve body 472D defines a second through hole 477D. The first through hole 476D connects the second space 474D and the first space 473D, and the second through hole 477D connects the first space 473D. The male terminal 410 is accommodated in the second space 474D and the first through hole 476D. In actual installation, the male terminal 410 is first inserted from the first sleeve portion 4711D into the first through hole 476D, and then further inserted into the second space 474D. The blocking portion 4713D is used to prevent the rigid circuit board 430D from entering the second space 474D. Then, the first sleeve portion 4711D and the second sleeve body 472D are connected together. For example, the first sleeve portion 4711D is provided with a first connecting structure 4714D, and the second sleeve body 472D is provided with a second connecting structure 4724D. The first connecting structure 4714D and the second connecting structure 4724D are fixedly connected. For example, the connection between the first connecting structure 4714D and the second connecting structure 4724D is smoothly transitioned. The connection methods between the first connecting structure 4714D and the second connecting structure 4724D include, but are not limited to: threaded connection, adhesive layer connection, snap-fit ​​connection, and heat fusion connection. During the insertion process between the male terminal 410 and the female terminal, at least a portion of the female terminal can be inserted into the second sleeve portion 4712D through the opening 475D.

[0136] For example, the diameter of the first sleeve portion 4711D is larger than the diameter of the second sleeve portion 4712D.

[0137] For example, the diameter of the second body 472D is equal to the diameter of the first sleeve part 4711D.

[0138] like Figure 28A , 28B The present application provides a lamp (10A, 10B, 10C, 10D, 10E, 10F, 10G, 10H, 10I, 10J, 10K, hereinafter referred to as 10A-K) for use with mains power. The lamp (10A-K) will be referred to as lamp (10A-K) in the following text. The lamp (10A-K) includes at least one lampshade (500A, 500B), at least one light-emitting element 400, at least one electrical connection device (1000A, 1000C, 1000D), and one electrical plug (640A, 640B).

[0139] Combination Figure 29A and 29B The lampshade (500A, 500B) includes a receiving space 530 and at least one opening (510, 520) communicating with the receiving space 530. Exemplarily, the lampshade 500A includes a receiving space 530 and an opening 510 communicating with the receiving space 530; in this embodiment, the opening 510 is defined as a first opening 510. The lampshade 500A also includes an internal thread 540 provided at the first opening 510; in this embodiment, the internal thread 540 is defined as a first internal thread 540. The lampshade 500A also includes a mounting groove 560 provided at the first opening 510, the mounting groove 560 being located outside the first opening 510. Figure 15A and Figure 15B The connector 1100 in the electrical connection device 1000A also includes a mounting structure 1115 disposed on the outer side 1112, with the mounting structure 1115 arranged around the outer side 1112. After the external thread 1114 and the first internal thread 340 of the lampshade (500A, 500B) are connected, the mounting structure 1115 is fitted onto the surface of the lampshade (500A, 500B). To increase the connection stability between the electrical connection device 1000A and the lampshade (500A, 500B), after the external thread 1114 and the first internal thread 340 of the lampshade (500A, 500B) are connected, the mounting structure 1115 is placed in the mounting groove 560, and the surface at the connection position between the mounting structure 1115 and the lampshade (500A, 500B) is smoothly transitioned, so that the connection position between the mounting structure 1115 and the lampshade (500A, 500B) is smooth.

[0140] The lampshade 500B includes a receiving space 530 and a first opening 510 and a second opening 520 communicating with the receiving space 530. For example, the first opening 510 and the second opening 520 are disposed opposite to each other. The lampshade 500B also includes a first internal thread 540 disposed at the first opening 510 and a second internal thread 550 disposed at the second opening 520. The lampshade 500A also includes a mounting groove 560 disposed at the first opening 510 and a mounting groove 560 disposed at the second opening 520, and the mounting grooves 560 are located outside the first opening 510 and the second opening 520. For example, the mounting structures 1115 of the two electrical connection devices 1000A are respectively installed into the mounting grooves 560.

[0141] Any light emitter 400 includes a rigid circuit board and a light-emitting element electrically connected to the rigid circuit board. The rigid circuit board is connected to a male terminal, the structure of which can be referenced to male terminal 200A or male terminal 200B, and will not be described further here. In one optional embodiment, the structure of the light emitter 400 can be referenced to light emitters (400A, 400B, 400C, 400D, 400E, 400F, 400M), and will not be described further here. In another optional embodiment, the light emitter 400 may further include a female terminal. The structure of the light emitter 400 including the female terminal can be referenced to light emitters (400G, 400H, 400I, 400J, 400K, 400L), and will not be described further here.

[0142] The light source 400 can be inserted into the receiving space 530 of the lampshade 500 through any opening (510, 520), and the light source 400 can be removed from the receiving space 530 through any opening (510, 520).

[0143] The electrical connection devices (1000A, 1000C, 1000D) can be referenced above and will not be repeated here. It should be noted that it is also feasible to replace electrical connection device 1000C or 1000D in some lamps with electrical connection device 1000B.

[0144] The female terminal 100 of the electrical connection device (1000A, 1000C, 1000D) can be inserted into and separated from the male terminal 410 of the light-emitting element 400. At least a portion of the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D) can be inserted together with the light-emitting element 400 into the receiving space 530 of the lampshade (500A, 500B) through any opening (510, 520). The connector 1100 of the electrical connection device (1000A, 1000C, 1000D) is detachably connected to the lampshade (500A, 500B). For example, the external thread 1124 of the connector 1100 can be connected to and separated from the first internal thread 540 or the second internal thread 550 of the lampshade (500A, 500B).

[0145] For example, during or after the insertion of the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D), the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D) can rotate relative to each other. This allows the electrical connection device (1000A, 1000C, 1000D) and the lampshade (500A, 500B) to be screwed together.

[0146] During or after the insertion of the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D), the first part 211 of the third electrode 210 will squeeze the first part (110A, 110B) of the first electrode (100A, 100B) to cause elastic deformation of the first part (110A, 110B) of the first electrode (100A, 100B), thereby ensuring close contact between the two; and the first part 121 of the second electrode 120 will squeeze the first part (221A, 221B) of the fourth electrode (220A, 220B) to cause elastic deformation of the first part (221A, 221B) of the fourth electrode (220A, 220B), thereby ensuring close contact between the two.

[0147] After the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D) are connected, the first part 211 of the third electrode 210 and the outer spacer 231 are located within the first spacer space 101, and the first part 211 of the third electrode 210 and the contacting parts (115A, 115B) of the first electrode (100A, 100B) are in contact. The first part (221A, 221B) of the fourth electrode (220A, 220B) and the inner spacer... The spacer 233 is located in the second space 102. The first part 121 of the second electrode 120 is located in the insertion space (2214A, 2214B) of the fourth electrode (220A, 220B). The first part 121 of the second electrode 120 and the first part (221A, 221B) of the fourth electrode (220A, 220B) are in contact, so as to realize the electrical connection between the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection device (1000A, 1000C, 1000D). The first part 211 of the third electrode 210 and the first part (110A, 110B) of the first electrode (100A, 100B) are separated from the first part 121 of the second electrode 120 and the first part (221A, 221B) of the fourth electrode (220A, 220B) by at least an inner spacer 233, an outer spacer 231 and a spacer 131 of the female seat 130.

[0148] The connection and disconnection states of the male terminal 410 of the light emitter 400 and the female terminal 100 of the electrical connection devices (1000A, 1000C, 1000D) can be referenced. Figure 9A , 9B The terminal assemblies 300A shown in 9C, 9D, 9E, 9F, 9G, 9H, 9I, 9J, 9K, and 9L will not be described in detail here.

[0149] The plugs (640A, 640B) are electrically connected to the female terminal 100 of an electrical connection device (1000A, 1000C, 1000D). The plugs (640A, 640B) are used to connect to mains power. For example, the plugs (640A, 640B) are inserted into a socket connected to mains power.

[0150] An alternative embodiment, such as Figure 28A , 28B28C, Lighting fixtures (10A, 10B, 10C) include a lampshade 500A, a light-emitting element 400, and an electrical connection device 1000A. The female terminal 100 of the electrical connection device 1000A of lighting fixture 10A is electrically connected to an electrical plug 640A via a wire 650A. The female terminal 100 of the electrical connection device 1000A of lighting fixture 10B is electrically connected to an electrical plug 640B via a wire 650B. The female terminal 100 of the electrical connection device 1000A of lighting fixture 10C is electrically connected to an electrical plug via a wire, and the connector 1100 of the electrical connection device 1000A of lighting fixture 10C is connected to a support base 11. The support base 11 can support the lampshade 500A, the electrical connection device 1000A, and the light-emitting element 400. The support base 11 can be placed in a predetermined position, such as on the ground or a table. It should be noted that support base 11 can also be replaced with a ground plug, for example, support base 11 can be replaced with... Figure 28H One of the plugins in it, number 12.

[0151] An alternative embodiment, such as Figure 28D , 28E The luminaires (10D, 10E, 10F, 10G) include multiple lampshades 500A, multiple light-emitting elements 400, and multiple electrical connection devices (1000C, 1000D). For example, the number of lampshades 500A, multiple light-emitting elements 400, and multiple electrical connection devices (1000C, 1000D) is the same. It should be noted that the multiple electrical connection devices (1000C, 1000D) in the luminaires (10D, 10E, 10F, 10G) of this application embodiment can also be replaced with electrical connection devices 1000B. The female terminals 100 of two adjacent electrical connection devices (1000C, 1000D) are connected by wires. In this design, the external thread 1114 of an electrical connector (1000C, 1000D) is connected to the first internal thread 540 at the first opening 510 of a lampshade 500A, and the female terminal 100 of the electrical connector (1000C, 1000D) is inserted into the male terminal 410 of a light-emitting element 400. The luminaires (10D, 10E, 10F, 10G) can be referred to as a string of lights. Figure 28D and Figure 28F This diagram illustrates a 640A electrical plug. Figure 28E and 28G Another type of plug 640B is shown. The plugs 640A and 640B have different structures.

[0152] An alternative embodiment, such as Figure 28HThe luminaire 10H includes multiple lampshades 500A, multiple light-emitting elements, and multiple electrical connection devices 1000A. For example, the number of lampshades 500A, light-emitting elements, and electrical connection devices 1000A is the same. Each electrical connection device 1000A is physically connected to a grounding plug 12, and the female terminal 100 of each electrical connection device 1000A is electrically connected to a wire 13.

[0153] An alternative embodiment, such as Figure 28I and 28J The luminaires (10I, 10J) include multiple lampshades 500B, multiple light-emitting elements 400, and multiple electrical connection devices (1000A). For example, the number of lampshades 500A and the number of light-emitting elements 400 are the same. The luminaires (10I, 10J) may include one electrical connection device 1000A or two electrical connection devices 1000A. This embodiment of the application uses two electrical connection devices 1000A as an example. Specifically, one electrical connection device 1000... A is connected to the electrical plugs (640A, 640B), and another electrical connection device 1000A is connected to the closed end of the lamps (10I, 10J). The closed end of the lamps (10I, 10J) and the electrical plugs (640A, 640B) are located at opposite ends of the lamps (10I, 10J). When there is only one electrical connection device 1000A, the lampshade at the end of the lamps (10I, 10J) furthest from the electrical plugs (640A, 640B) adopts the structure of lampshade 500A, while the other lampshades adopt the structure of lampshade 500B.

[0154] The luminaire (10I, 10J) also includes at least one terminal assembly 300, wherein the terminal assembly 300 can be one of terminal assembly 300B, terminal assembly 300C, or terminal assembly 300D. The terminal assembly 300 includes male and female terminals, which are connected via wires or directly. The terminal assembly 300 is physically connected to two adjacent lampshades 500B, and the terminal assembly 300 is detachable from the lampshades 500B. Specifically, the first external thread and the second external thread of the terminal assembly 300 are threadedly connected to the first internal thread and the second internal thread of the lampshade 500B. The male terminal of the terminal assembly 300 is inserted into the female terminal of one of the light-emitting elements 400, and the female terminal of the terminal assembly 300 is inserted into the male terminal of the other light-emitting element 400. The male terminal structure in the terminal assembly 300 and the male terminal in the light emitter 400 can refer to male terminal 200A or male terminal 200B. The female terminal structure in the terminal assembly 300 and the female terminal structure in the light emitter 400 can refer to female terminal 100A or female terminal 100B. They will not be described in detail here.

[0155] For example, the light-emitting element 400 in the luminaire (10I, 10J) is further encased in a jacket. The jacket surrounds the rigid circuit board of the light-emitting element 400 to cover at least one light-emitting element. The jacket is light-transmitting, allowing light emitted by the light-emitting element covered by the jacket to pass through it. The jacket also surrounds the female terminal of the light-emitting element 400 to confine the female terminal of the light-emitting element 400 within the jacket. After the male terminal of the light-emitting element 400 and the female terminal of the terminal assembly 300 are plugged in, a portion of the female terminal of the terminal assembly 300 is surrounded by the jacket. The jacket can be referenced to jacket 470J, which will not be described further here.

[0156] An alternative embodiment, such as Figure 28K The luminaire 10K includes multiple light strings, such as a first light string 10K1 and a second light string K2. Each light string, such as the first light string 10K1 and the second light string K2, can be referenced in luminaires 10I and 10J. Each light string, such as the first light string 10K1 and the second light string K2, includes one or two electrical connection devices, such as electrical connection devices 1000C, at least one terminal assembly 300, and multiple lamp shades 500B. It should be noted that in this embodiment, each light string, such as the first light string 10K1 and the second light string K2, includes a lamp shade 500A, which can also be replaced with a lamp shade 500B. The light strings, such as the first light string 10K1 and the second light string K2, are physically and electrically connected by wires.

[0157] For other alternative embodiments, please refer to Figure 30A , 30B 30C, 31A, 31B and 31C, this embodiment also provides a mains power connection device 4100 and a lamp 10R having the connection device 4100.

[0161] The female connector 4110 includes a plug-in end face 4114 and two electrode grooves 4115 penetrating the plug-in end face 4114. One electrode (4121 or 4122) of the female terminal 4101 is disposed within one electrode groove 4115, and the distance between any one electrode (4121 or 4122) of the female terminal 4101 and the plug-in end face 4114 is greater than 0, so as to confine at least two electrodes (4121, 4122) of the female terminal 4101 within the electrode groove 4115 of the female connector 4110. During the gold finger testing process, neither electrode (4121 or 4122) of the female terminal 4101 will be touched.

[0162] At least two electrodes (4231, 4232) of the male terminal 4230 and at least two electrodes (4121, 4122) of the female terminal 4101 can be plugged in and disconnected from each other. When the male terminal 4230 and the female terminal 4101 are plugged in, they are electrically connected. Specifically, the first electrode 4121 of the female terminal 4101 and the third electrode 4231 of the male terminal 4230 are both positive electrodes and can be plugged in to achieve an electrical connection. The second electrode 4122 of the female terminal 4101 and the fourth electrode 4232 of the male terminal 4230 are both negative electrodes and can be plugged in to achieve an electrical connection.

[0163] For example, one or more lampshades 4300 also include an internal thread 4340 disposed at the opening 4310, and the female terminal 4101 also includes an external thread 4112 disposed on the outer side of the female base 4110, the external thread 4112 and the internal thread 4340 being connected. When at least two electrodes (4231, 4232) of the male terminal 4230 and at least two electrodes (4121, 4122) of the female terminal 4101 are in the plugged-in state, the light emitter 4200 and the connecting device 4100 can rotate together about an axis such as the tenth axis P10.

[0164] For example, one or more lampshades 4300 also include a mounting groove communicating with the opening 4310, and the female terminal 4101 also includes a mounting portion 4113, which is disposed adjacent to the external thread 4112. When the internal thread 4340 and the external thread 4112 are in the connected state, the mounting portion 4113 is installed in the mounting groove. The mounting groove of the lampshade 4300 can be referred to as the mounting groove 560, and will not be described in detail here.

[0165] For example, the female terminal includes an external thread 4112 and a mounting portion 4113, and the female seat 4110 includes a plug-in portion 4111. The plug-in portion 4111, the external thread 4112 and the mounting portion 4113 are arranged sequentially along the axis of the female terminal 4101, such as the tenth axis P10. The plug-in end face 4114 is located at the end of the plug-in portion 4111 away from the external thread 4112. The external thread 4112 and the mounting portion 4113 are located on the outer side of the female seat 4110.

[0166] For example, the outer diameter of the insertion portion 4111, the outer diameter of the external thread 4112, and the outer diameter of the mounting portion 4113 increase sequentially.

[0167] For example, the outer surface of the plug portion 4111 includes a connected arcuate surface 4116 and a flat surface 4117. In other alternative embodiments, the outer surface of the plug portion 4111 may also have other structures, such as a ring structure.

[0168] The first electrode 4121, the second electrode 4122, and the external thread 4112 of the female terminal 4101 can rotate together around an axis, such as the tenth axis P10. In this embodiment, the first electrode 4121 and the second electrode 4122 are not coaxially arranged, for example, they are arranged side by side.

[0169] In this embodiment, the connected light-emitting body 4200 and the female terminal 4101 can rotate together around an axis such as the tenth axis P10. For example, the connected light-emitting body 4200 and the female terminal 4101 can rotate relative to a lampshade 4300 to realize the connection and disconnection of the female terminal 4101 and the lampshade 4300.

[0170] For example, the connecting device 4100 may also include a mounting body 4130, which is connected to the female connector 4110 and is located at the end away from the electrode groove 4115. The mounting body 4130 can be referred to as mounting bodies 1130B, 1130C and mounting structure 1130D, which will not be described in detail here.

It should be noted that the electrical plug 4400 can refer to electrical plug 640B or electrical plug 640A, and will not be described in detail here.

[0172] In this embodiment of the application, at least two electrodes of the female terminals of the connecting device 4100 and the light emitter 4200 are provided with insulating material and are spaced apart within the insulating material to achieve physical isolation and prevent short circuits.

[0173] For other alternative embodiments, please refer to Figure 32A , 32B 32C, 32D, 32E, 33A, 33B, 34A and 34B, this embodiment also provides a mains power connection device 5100 and a lamp 10S having the connection device 5100. The lamp 10S for mains power is simply referred to as lamp 10S. The lamp 10S includes a plurality of first connection devices 5100, a plurality of second connection devices 5200, a plurality of light-emitting elements 5300 and a plurality of lamp covers 5400.

[0174] Some lampshades 5400 include a first opening 5410, a second opening 5420, and a receiving space 5430 communicating with the first opening 5410 and the second opening 5420.

[0175] Some light emitters 5300 include a rigid circuit board 5310, one or more light-emitting elements 5320 electrically connected to the rigid circuit board 5310, and a female terminal 5340 and a male terminal 5330 physically and electrically connected to the rigid circuit board 5310.

[0176] Some first connection devices 5100 include one or more female terminals 5101, each female terminal 5101 including at least two electrode elements 5116 disposed within an insulating material. For example, the female terminal 5101 may include an insulating component 5110 made of insulating material, with the at least two electrode elements 5116 disposed within the insulating component 5110, preventing contact with the at least two electrode elements 5116 during gold finger testing.

For example, the male terminal 5201 may include an insulating component 5210 made of an insulating material, with at least a portion of the male terminal 5201 disposed within the insulating component 5210.

[0178] A lampshade 5400 is connected between a first connecting device 5100 and a second connecting device 5200. The female terminal 5101 of the first connecting device 5100 and the male terminal 5201 of the second connecting device 5200 are connected to the lampshade 5400 through a locking member 5500.

[0179] A light-emitting element 5300 is connected between a first connecting device 5100 and a second connecting device 5200. The male terminal 5330 of the light-emitting element 5300 and the female terminal 5101 of the first connecting device 5100 can be plugged in and disconnected. When the male terminal 5330 of the light-emitting element 5300 and the female terminal 5101 of the first connecting device 5100 are plugged in, at least two electrodes 5331 of the male terminal 5330 of the light-emitting element 5300 are electrically connected to at least two electrodes 5116 of the female terminal 5101 of the first connecting device 5100. For example, the male terminal 5330 includes two electrode elements 5331, such as one being a positive electrode element and the other being a negative electrode element, and the female terminal 5101 includes two electrode elements 5116, such as one being a positive electrode element and the other being a negative electrode element. The positive electrode element of the male terminal 5330 and the positive electrode element of the female terminal 5101 are electrically connected, and the negative electrode element of the male terminal 5330 and the negative electrode element of the female terminal 5101 are electrically connected.

[0180] A female terminal 5340 of a light-emitting element 5300 and a male terminal 5201 of a second connecting device 5200 can be plugged in and disconnected. When the female terminal 5340 of the light-emitting element 5300 and the male terminal 5201 of the second connecting device 5200 are plugged in, at least two electrodes 5344 of the female terminal 5340 of the light-emitting element 5300 are electrically connected to at least two electrodes 5216 of the male terminal 5201 of the second connecting device 5200. For example, the female terminal 5340 includes two electrodes 5344, such as one positive electrode and the other negative electrode, and the male terminal 5201 includes two electrodes 5216, such as one positive electrode and the other negative electrode. The positive electrode of the male terminal 5201 is electrically connected to the positive electrode of the female terminal 5340, and the negative electrode of the male terminal 5201 is electrically connected to the negative electrode of the female terminal 5340.

[0181] One of the first connecting devices 5100 has a female terminal 5101 serving as a signal input terminal for the lamp 10S. For example, the female terminal 5101 is electrically connected to a power plug 5700 via a wire 5102, and the power plug 5700 can be connected to mains power.

[0182] For example, the female terminal 5101 of the first connecting device 5100 and the male terminal 5201 of the second connecting device 5200 both include connected inner connecting portions (5112 and 5212) and outer connecting portions (5111 and 5211). Some lampshades 5400 also include a first mounting plate 5440 disposed at the first opening 5410 and a second mounting plate 5450 disposed at the second opening 5420. Some lampshades 5400 also include a first mounting groove 5460 communicating with the first opening 5410 and a second mounting groove 5470 communicating with the second opening 5420. The inner connecting portions (5112 and 5212) are disposed within the first opening 5410 or the second opening 5420 and are limited by the first mounting plate 5440 or the second mounting plate 5450. The external connecting portions (5111 and 5211) are disposed in the first mounting slot 5460 or the second mounting slot 5470 and terminate in the first mounting plate 5440 or the second mounting plate 5450, and the external connecting portions (5111 and 5211) are connected to the first mounting plate 5440 or the second mounting plate 5450 via the locking member 5500. The locking component 5500 is, for example, a screw or bolt. The outer connecting part 5111 has a locking hole 5103, the outer connecting part 5211 has a locking hole 5203, and the first mounting plate 5440 and the second mounting plate 5450 both have locking holes 5401. The locking component 5500 can be installed into the locking holes 5103 and 5401 to lock the first connecting device 5100 and the lamp cover 5400, and the locking component 5500 can be installed into the locking holes 5203 and 5401 to lock the second connecting device 5200 and the lamp cover 5400.

[0183] For example, the outer diameter of the inner connecting portions (5112 and 5212) is smaller than the outer diameter of the outer connecting portions (5111 and 5211). A stepped structure can be formed between the inner connecting portions (5112 and 5212) and the outer connecting portions (5111 and 5211).

[0184] For example, both the first mounting plate 5440 and the second mounting plate 5450 are provided with at least one limiting groove 5480. The limiting groove 5480 is disposed on the periphery of the first mounting plate 5440 and the second mounting plate 5450. The outer side of the inner connecting portion 5112 is provided with at least one limiting structure 5119, and the outer side of the inner connecting portion 5212 is provided with at least one limiting structure 5219. The limiting structures (5119 and 5219) are disposed in the limiting groove 5480, thereby restricting the relative rotation of the first connecting device 5100 and the lampshade 5400 and restricting the relative rotation of the second connecting device 5200 and the lampshade 5400.

[0185] For example, a waterproof groove 5490 is formed on the outer surface of both the first mounting plate 5440 and the second mounting plate 5450. The lamp 10S also includes a plurality of waterproof pads 5600, one of which is disposed within a waterproof groove 5490. The waterproof pad 5600 is disposed between the first mounting plate 5440 or the second mounting plate 5450 and the external connecting parts (5111 and 5211). For example, the lamp cover 5400 also includes a limiting ring 5402 disposed on the first mounting plate 5440 and the second mounting plate 5450, and the limiting groove 5480 terminates at the position of the limiting ring 5402.

[0186] For example, the female terminal 5101 of the first connecting device 5100 includes an insulating member 5110. The insulating member 5110 includes a plug-in end face 5114 and at least two electrode grooves 5115 extending through the plug-in end face 5114. One electrode 5116 of the female terminal 5101 is disposed within one electrode groove 5115, and the distance between any one electrode 5116 of the female terminal 5101 and the plug-in end face 5114 is greater than 0, so as to confine at least two electrodes 5116 of the female terminal 5101 within the electrode groove 5115 of the insulating member 5110. During the gold finger detection process, the at least two electrodes 5116 of the female terminal 5101 cannot be touched. For example, the insulating member 5110 also includes a plug-in portion 5113, which is connected to an inner connecting portion 5112, and the inner connecting portion 5112 is connected between the plug-in portion 5113 and the outer connecting portion 5111. The insertion end face 5114 is located at the end of the insertion portion 5113 away from the inner connecting portion 5112, and at least a portion of the electrode groove 5115 is formed within the insertion portion 5113. For example, the outer diameter of the insertion portion 5113 is smaller than the outer diameter of the inner connecting portion 5112 and the outer diameter of the outer connecting portion 5111, which facilitates the insertion portion 5113 being inserted into the receiving space 5130 from the first opening 5410 or the second opening 5420.

[0187] For example, the male terminal 5201 of the second connecting device 5200 includes an insulating member 5210. The insulating member 5210 includes a sleeve 5213, which is connected to an inner connecting portion 5212, and the inner connecting portion 5212 is located between the sleeve 5213 and the outer connecting portion 5211. The sleeve 5213 defines a insertion space 5215, and a portion of the electrode 5216 of the male terminal 5201 is disposed within the insertion space 5215, that is, a portion of the electrode 5216 of the male terminal 5201 is surrounded by the sleeve 5213, and the inner surfaces of the electrode 5216 and the sleeve 5213 are spaced apart. The insertion space 5215 can accommodate a portion of the female terminal 5340 of the light emitter 5300. For example, the outer diameter of the sleeve 5213 is smaller than the outer diameter of the inner connecting portion 5212 and the outer connecting portion 5211, which facilitates the insertion of the sleeve 5213 into the receiving space 5130 from the first opening 5410 or the second opening 5420.

[0188] For example, the female terminal 5340 of the light emitter 5300 includes an insulating component 5341, which includes a plug-in end face 5342. The insulating component 5341 also includes at least two electrode grooves 5343 penetrating the plug-in end face 5342. One electrode 5344 of the female terminal 5340 is disposed within one electrode groove 5343, and the distance between any one electrode 5344 of the female terminal 5340 and the plug-in end face 5342 is greater than 0, so as to confine at least two electrodes 5344 of the female terminal 5340 inside the electrode groove 5343 of the insulating component 5341, so that at least two electrodes 5344 of the female terminal 5340 cannot be touched during the gold finger detection process. A portion of the insulating component 5341 and a portion of the electrode 5344 of the female terminal 5340 can be inserted into the plug-in space 5215 of the male terminal 5201 to achieve electrical connection between the electrode 5344 and the electrode 5216.

[0189] For example, the electrode 5331 of the male terminal 5330 of the light emitter 5300 may be exposed or at least partially disposed within the insulating component 5332.

[0190] In some alternative embodiments, the rigid circuit board 5310 and the light-emitting element 5320 may be disposed within the insulating components 5332 and 5341. The insulating components 5332 and 5341 can be connected together.

[0191] For example, the outer surface of the plug portion 5113 includes a connected arcuate surface 5117 and a flat surface 5118. In other alternative embodiments, the outer surface of the plug portion 5113 may also have other structures, such as a circular structure.

[0192] For example, the outer surface of the sleeve 5213 includes a connected arcuate surface 5217 and a plane 5218.

[0193] For example, all the female terminals of the luminaire 10S serve as signal input terminals to which all the male terminals are plugged.

[0194] For example, the first connecting device 5100 and the second connecting device 5200 located between the two lampshades 5400 can be directly or indirectly connected. For instance, adjacent first connecting devices 5100 and second connecting devices 5200 are physically and electrically connected through wires 5102 and 5202.

[0195] In this embodiment of the application, at least two electrodes of the female terminals of the first connecting device 5100 and the light emitter 5300 are provided with insulating material and are spaced apart within the insulating material to achieve physical isolation and prevent short circuits.

[0196] In the above embodiments, the arrangement of all male and female terminals of the lamp is as follows: starting from the plug end, female terminal, male terminal, female terminal, male terminal, female terminal, male terminal, female terminal, male terminal, female terminal, male terminal... In all the above embodiments, the electrodes of all female terminals are wrapped in insulating material and located inside the insulating material, so that the electrodes of all female terminals of the lamp cannot be touched during the gold finger detection process.
