Description

Technical Field

[0001] This disclosure belongs to the field of terminal block technology, specifically relating to an electrode contact and a terminal block. Background Technology

[0002] Terminal blocks are used to reliably connect different wires or cables in a circuit, allowing current to flow smoothly and ensuring normal circuit conduction. For example, in a lighting circuit, the power cord of the lamp is connected to the power supply line through a terminal block, allowing current to flow from the power source to the lamp, causing it to emit light. A terminal block has input and output terminals. The input terminal is typically a power input terminal or a signal source terminal. For example, in LED lamps, the power input terminal corresponds to the power cord or the controller's output terminal, used to provide electrical energy or control commands. The output terminal is typically a load terminal or device terminal, connected to the load device or internal circuitry, such as LED chips or driver modules, ensuring stable electrical contact.

[0003] In current terminal blocks, the contact pieces at the input and output ends are usually arranged on the same horizontal plane along the length of the housing to ensure uniform contact between the wires and the metal pieces. However, this arrangement of contact pieces results in larger hardware sizes and higher costs. Utility Model Content

[0035] To enable those skilled in the art to better understand the technical solutions of this disclosure, the disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this disclosure and represent a part of the embodiments of this disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the protection scope of this disclosure.

[0036] like Figures 1 to 4 As shown, one aspect of this disclosure provides an electrode contact 100, comprising: a fixing member 110 and a bent contact 120; wherein the fixing member 110 includes a first fixing portion 111 and a second fixing portion 112 disposed opposite to each other, and a support portion 113 respectively connected to the first fixing portion 111 and the second fixing portion 112; the bent contact 120 includes a contact connection portion 121 and one or two first bent portions 122 and second bent portions 123 respectively connected to both ends of the contact connection portion 121 along its length direction, wherein the first bent portion 122 is... The contact connection portion 121 bends toward the first fixing portion 111, and one or two first bending portions 122 bend from the contact connection portion 121 toward the first fixing portion 111 to form one or two first insertion structures. The second bending portion 123 bends from the contact connection portion 121 toward the second fixing portion 112 to form a second insertion structure. The insertion directions of the first insertion structure and the second insertion structure are opposite and arranged in a vertical direction.

[0037] In this embodiment, by bending the contact element, the electrode contact element forms a first and a second wiring structure with different wiring directions along its vertical direction. The first wiring structure can serve as an output end, i.e., an assembly end for the lighting fixture. The number of first bends can be one or two, forming one or two first wiring structures to meet different electrical connection requirements. In this case, the first wiring structure is used to insert electrical connection wires. Secondly, the second wiring structure can serve as an input end, i.e., a power input end. In this case, the second wiring structure is used to insert power lines. This forms a double-layer wiring structure along the vertical direction, which helps to reduce the size of the wiring terminals and lower costs.

[0038] It should be noted that in the first fixing part and the second fixing part arranged opposite to each other, the first fixing part is located below and the second fixing part is located above. The first bending part bends downward from the contact connection part and the second bending part bends upward from the contact connection part, forming an upper and lower two-layer plug-in structure.

[0039] It should be further noted that this embodiment does not specifically limit the number of first bending structures. One or two first bending structures can be set according to the actual electrical connection requirements. Of course, the one or two first bending structures here should be integrally connected with the contact connection part. For example, two first bending structures can be connected side by side to the contact connection part.

[0040] Furthermore, such as Figures 1 to 4 As shown, the contact connection portion 121 includes a connection portion 121a arranged parallel to the first fixing portion 111, a first contact limiting portion 121b bent from one end of the connection portion 121a toward the first fixing portion 111, and a second contact limiting portion 121c bent from the other end of the connection portion 121a toward the second fixing portion 112. That is, the first contact limiting portion bends downward and the second contact limiting portion bends upward.

[0041] Furthermore, such as Figures 1 to 4 As shown, the first bending portion 122 includes a first extending structure 122a extending outward from the second contact limiting portion 121c and a first bending structure 122b extending inward from the first extending structure 122a towards the first fixing portion 111. The end of the first bending structure 122b abuts against the first fixing portion 111. When the electrical connection wire is inserted, the end of the first bending structure 122b springs upward and abuts against the connection area of ​​the second contact limiting portion 121c and the connection portion 121a. Here, the connection area of ​​the second contact limiting portion 121c and the connection portion 121a plays a limiting role. At the same time, the end of the first bending structure 122b presses the electrical connection wire against it, playing a role in securing the wire.

[0042] It should be understood that the end of the first bending structure is equivalent to the wire clamping structure of the electrical connection wire, which serves to hold it in place. The connecting part, the first contact limiting part, and the first fixing part surround and form the insertion cavity of the first insertion structure. Furthermore, the first contact limiting part can limit the insertion depth of the electrical connection wire.

[0043] Furthermore, such as Figures 1 to 4 As shown, the second bending portion 123 includes a second extension structure 123a extending outward from the first contact limiting portion 121b and a second bending structure 123b extending inward from the second extension structure 123a towards the inside of the second fixing portion 112. When the power cord is inserted, the end of the second bending structure 123b springs up and abuts against the connection area between the first contact limiting portion 121b and the connection portion 121a. Here, the connection area between the first contact limiting portion 121b and the connection portion 121a serves as a limiting function, eliminating the need for other limiting structures. At the same time, the end of the second bending structure 123b presses the power cord against it, serving as a cable clamp.

[0044] Similarly, the end of the second bending structure is also equivalent to the power cord clamping structure, which serves to hold the power cord tightly. The connecting part, the second contact limiting part, and the second fixing part surround and form the insertion cavity of the second insertion structure. Furthermore, the second contact limiting part can limit the insertion depth of the power cord.

[0045] Furthermore, such as Figures 1 to 4 As shown, the support portion 113 is provided with a first snap-fit ​​structure 113a, and the first extension structure 122a is snapped into the first snap-fit ​​structure 113a and abuts against the second fixing portion 112. That is, the first extension structure is fixed to the second fixing portion by the first snap-fit ​​structure.

[0046] It should be noted that this embodiment does not specifically limit the first snap-fit ​​structure; for example, such as Figure 3 As shown, the first snap-fit ​​structure 113a is inclined from the support portion 113 toward the second fixing portion 112, so that the first extension structure is snapped between the first snap-fit ​​structure and the second fixing portion. Of course, the first snap-fit ​​structure can be a structure separately provided on the support portion, or it can be an integral structure in which part of the support portion is cut open and inclined.

[0047] Furthermore, such as Figures 1 to 4 As shown, a second snap-fit ​​structure 111a is provided at the end of the first fixing part 111, and the second extension structure 123a is snapped into the second snap-fit ​​structure 111a. That is, the second extension structure is fixed to the first fixing part by the second snap-fit ​​structure.

[0048] It should be noted that this embodiment does not specifically limit the second snap-fit ​​structure, such as... Figure 1 and Figure 3 As shown, the second snap-fit ​​structure includes two opposing first snap-fit ​​protrusions. The second extension structure 123a has first snap-fit ​​grooves 123c on both sides, and the first snap-fit ​​protrusions are engaged in the first snap-fit ​​grooves 123c. Note that the first snap-fit ​​protrusions can bend upwards and inwards from both sides of the first fixing part. Correspondingly, the second extension structure has inwardly recessed first snap-fit ​​grooves on both sides. Thus, the first snap-fit ​​protrusions are engaged in the first snap-fit ​​grooves, achieving the riveting of the fixing member and the second bent part.

[0049] Furthermore, such as Figures 1 to 4 As shown, the second bending structure 123b has a second slot 123d near its end area. The second slot 123d is used to engage the pressing part, prevent the pressing part from sliding, and facilitate the unwinding of the pressing part.

[0050] It should be noted that this embodiment does not specifically limit the number and structure of the second card slots. For example, such as Figure 1and Figure 4 As shown, two second slots 123d are provided in the second bending structure 123b along its width direction.

[0051] It should also be noted that the bending contact in this embodiment is preferably made of stainless steel, and the fastener is preferably made of copper. Of course, the bending contact and the fastener can also be made of other materials, as long as they meet the requirements of conductivity and bendability. No specific limitations are imposed on this.

[0052] like Figures 5 to 8 As shown, another aspect of this disclosure provides a terminal block 200, including a housing 210, at least two electrode contacts 100 and at least two pressing members 220, wherein the electrode contacts are the electrode contacts described above, and the specific structure can be referred to the above description, which will not be repeated here, and the electrode contacts are located inside the housing; and one pressing member 220 corresponds to one electrode contact 100.

[0053] It is easy to understand that the pressing member in this embodiment should correspond to the power input terminal of the electrode contact member. That is, the pressing member corresponds to the second bending structure in the second bending portion of the electrode contact member. When it is necessary to retract the wire, the power line is retracted by pressing the pressing member.

[0054] It should also be understood that the pressing component should include a pressing part protruding outside the housing and an abutting part penetrating inside the housing, the pressing part being used for user pressing and the abutting part being used for contacting the electrode contact.

[0055] Furthermore, such as Figure 4 and Figure 5 As shown, a second engaging protrusion 221 is provided at the end of the pressing member 220 facing away from the outer casing 210. This second engaging protrusion 221 engages in the second slot 123d of the electrode contact member 100. In other words, the second engaging protrusion 221 is provided at the abutting portion of the pressing member 220, and the pressing member 220 is limited by the second engaging protrusion 221 engaging in the second slot 123d of the electrode contact member.

[0056] It should also be understood that the housing should be provided with wire insertion holes corresponding to the first and second wiring structures. For example, the housing may have at least two sets of electrical connection wire insertion holes and at least two sets of power cord insertion holes. Each set of electrical connection wire insertion holes corresponds to the first wiring structure of each electrode contact. When each electrode contact includes two first wiring structures, each set of electrical connection wire insertion holes should include two insertion holes. Each set of power cord insertion holes corresponds to the second wiring structure of each electrode contact, and each set of power cord insertion holes includes one insertion hole.

[0057] It should be noted that this embodiment does not specifically limit the number of electrode contacts. For example, in some embodiments, when the terminal includes two electrode contacts, one for connecting the positive and one for the negative poles, two pressing members should be provided accordingly. Simultaneously, two sets of electrical connection wire insertion holes and two sets of power cord insertion holes should be provided on opposite sides of the housing. In other embodiments, when the terminal includes three electrode contacts, one for grounding and one for connecting the positive and negative poles, three pressing members should be provided accordingly. Simultaneously, three sets of electrical connection wire insertion holes and three sets of power cord insertion holes should be provided on opposite sides of the housing.

[0058] Specifically, such as Figures 6 to 8 As shown, two sets of electrical connection wire insertion holes 230 are provided on one side of the outer casing 210. These two sets of electrical connection wire insertion holes 230 correspond to the first insertion structures of the two electrode contacts 100, respectively. Each set of electrical connection wire insertion holes 230 includes two insertion holes, serving as the electrical connection terminals of the lamp manufacturer. Of course, it should be understood that this embodiment is only described using two electrode contacts as an example. In other embodiments, three electrode contacts can be provided. When three electrode contacts are provided, three sets of first insertion structures can be provided, corresponding to three sets of electrical connection wire insertion holes, which will not be listed here.

[0059] Specifically, such as Figures 6 to 8 As shown, two sets of power cord insertion holes 240 are provided on the other side of the housing 210. These two sets of power cord insertion holes 240 correspond to the second insertion structure of the two electrode contacts 100 respectively. Each set of power cord insertion holes 240 includes an insertion hole, which serves as the power input terminal of the client.

[0060] Furthermore, in other preferred embodiments, the housing may also be provided with a connection and fixing structure, such as fixing feet, through which the wiring terminals can be fixed to other accessories.

[0061] This disclosure provides an electrode contact and a terminal block, which have the following advantages over the prior art:

[0062] First, by setting two wire insertion structures in the vertical direction in the electrode contact, the present disclosure forms an upper and lower two-layer wire insertion structure, which can effectively reduce product size and reduce cost; at the same time, for the output end, one or two first insertion structures can also be formed to meet different electrical connections.

[0063] Secondly, this disclosure, through the bending design of the bent contact component, establishes two limiting parts at the two ends of the connecting portion when the power cord is inserted, forming connection areas with the first and second contact limiting parts respectively, thereby limiting the ends of the second and first bent structures. Simultaneously, the first and second contact limiting parts can also limit the wires inserted into the first and second plug-in structures respectively, eliminating the need for additional limiting structures and effectively simplifying the product structure.

[0064] Third, this disclosure achieves the snap-fit ​​fixing of the first bend and the second bend by setting a snap-fit ​​structure on the fastener.

[0065] Fourth, this disclosure provides a slot in the second bend, which engages with the snap-fit ​​protrusion of the pressing part to limit the end of the pressing part and prevent the pressing part from sliding during pressing.

[0066] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
