Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a rotatable terminal block for wire connection. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections and fall under the category of connectors in industry. Their core structure is a metal sheet encapsulated in insulating plastic with wire insertion holes at both ends. By tightening or loosening screws, wiring can be flexibly connected or disconnected. They avoid the tedious process of soldering or winding wires, support quick assembly and disassembly, and are especially suitable for circuit scenarios that require frequent adjustments.

[0003] The terminals at both ends of existing terminal blocks are basically fixed. When wiring, the cable needs to be wired according to the angle of the terminal block. In more complex wiring environments, the fixed-angle wiring method may lead to inconvenience in wiring and excessive bending of the cable. Especially when connecting thicker cables, the cable itself is difficult to bend, resulting in poor environmental adaptability of existing terminal blocks.

[0004] To address this, this application proposes a rotatable terminal block for wire connection, which improves adaptability to complex wiring environments by adjusting the angle of the terminal block. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a rotatable terminal block for wire connection, so as to solve the problem of poor adaptability in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a rotatable terminal block for wire connection, including a first wiring mechanism and a second wiring mechanism, wherein the ends of the first wiring mechanism and the second wiring mechanism are hinged to each other. The first wiring mechanism includes a first terminal head, one end of which is provided with a hinge groove. The inner wall of the hinge groove is provided with a plurality of annular isolation plates at equal intervals. Each isolation plate is provided with an elastic conductive plate on its wall surface. The other end of the first terminal head is provided with a first terminal post that matches the number of elastic conductive plates. Each first terminal post is connected to a corresponding elastic conductive plate. The second wiring mechanism includes a second terminal head, one end of which is provided with a hinge plate. The hinge plate has a hinge shaft at its center. The hinge plate is disposed inside a hinge groove and connected by the hinge shaft. The surface of the hinge plate is provided with conductive electrode posts that match the number of elastic conductive sheets. All the conductive electrode posts abut against the corresponding elastic conductive sheets. The other end of the second terminal head is provided with second terminals that match the number of conductive electrode posts. Each second terminal post is connected to a corresponding conductive electrode post.

[0007] Preferably, the isolation plates are respectively disposed on the inner walls of the upper and lower sides of the hinge groove, and the conductive electrode posts are respectively disposed on the upper and lower sides of the hinge plate and adapted to the isolation plates.

[0008] Preferably, the edges of the inner walls on both the upper and lower sides of the hinge groove are provided with barriers, the height of the isolation plate is equal to the height of the barriers, and the outer surface of the hinge plate abuts against the surface of the barriers.

[0009] Preferably, the elastic conductive sheet is made of shape memory metal, the elastic conductive sheet is wavy, and the conductive electrode post can be located at the trough of the wave of the elastic conductive sheet.

[0010] Preferably, the first terminal and the second terminal are both one or a combination of bolts, slots, quick connectors.

[0011] Preferably, the height of the top of the first terminal and the second terminal does not exceed the height of the top of the first terminal head and the second terminal head, respectively.

[0012] Preferably, an openable protective cover is provided above both the first terminal and the second terminal, and a wire passage groove is provided on the side of the protective cover.

[0013] As described above, the rotatable terminal block for wire connection of this utility model has the following beneficial effects: 1. This utility model provides a hinge groove at the end of the first terminal head, and sets multiple isolation plates inside the hinge groove to separate multiple independent areas. An elastic conductive plate is set on the wall of the isolation plate and connected to the first terminal post. At the same time, a hinge plate is set at the end of the second terminal head and is hinged inside the hinge groove by a hinge shaft. The circuit is connected by the cooperation of the conductive electrode post and the elastic conductive plate. This achieves improved adaptability to complex wiring environments by rotating the wiring angle.

[0014] 2. This utility model uses a shape memory metal to make an elastic conductive sheet, and sets the elastic conductive sheet in a wave shape. The conductive electrode post is limited by the valley of the wave shape, thereby forming a damping structure to avoid the connection between the hinge groove and the hinge plate being too flexible, thus achieving the effect of limiting the rotation angle.

Detailed Implementation

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, this utility model provides a rotatable terminal block for wire connection, including a first wiring mechanism 1 and a second wiring mechanism 2. The ends of the first wiring mechanism 1 and the second wiring mechanism 2 are hinged to each other. The angle between the first wiring mechanism 1 and the second wiring mechanism 2 can be adjusted by rotating the hinge to adapt to different wiring environments. Specifically, the first wiring mechanism 1 includes a first terminal head 11, the interior of which is provided with a cavity for wiring, and the outer surface of the first terminal head 11 is made of insulating material; one end of the first terminal head 11 is provided with a hinge groove 12, and the inner wall of the hinge groove 12 is provided with a plurality of annular isolation plates 13 at equal intervals to divide the hinge groove 12 into a plurality of equidistant regions, and the wall surface of each isolation plate 13 is provided with an elastic conductive plate 14 for electrical connection with the second wiring mechanism 2; the other end of the first terminal head 11 is provided with a first terminal post 15 that matches the number of elastic conductive plates 14, and each first terminal post 15 is connected to a corresponding elastic conductive plate 14; after the external cable is connected to the corresponding first terminal post 15, it can be electrically connected to the second wiring mechanism 2 through the elastic conductive plate 14; The second wiring mechanism 2 includes a second terminal head 21, which has the same structure and material as the first terminal head 11. One end of the second terminal head 21 is provided with a hinge plate 22, and the axis of the hinge plate 22 is provided with a hinge shaft 23. The hinge plate 22 is located inside the hinge groove 12 and connected by the hinge shaft 23, so that when rotating, the first terminal head 11 and the second terminal head 21 rotate around the hinge shaft 23. The surface of the hinge plate 22 is provided with conductive electrode posts 24 that match the number of elastic conductive sheets 14. All conductive electrode posts 24 abut against the corresponding elastic conductive sheets 14. The other end of the second terminal head 21 is provided with second terminals 25 that match the number of conductive electrode posts 24. Each second terminal post 25 is connected to the corresponding conductive electrode post 24. External cables are connected to the first terminal post 15 and the second terminal post 25 respectively. The connected cables can be connected through the cooperation of the elastic conductive sheets 14 and the conductive electrode posts 24 to achieve the purpose of wiring. At the same time, this terminal has a simple structure, can be easily manufactured, and has a low manufacturing cost.

[0026] It should be noted that in some embodiments, the isolation plate 13 of this utility model is respectively disposed on the inner walls of the upper and lower sides of the hinge groove 12, and the conductive electrode post 24 is respectively disposed on the upper and lower sides of the hinge plate 22 and adapted to the isolation plate 13. By using the isolation plate 13 and the conductive electrode post 24 to limit the upper and lower sides of the hinge plate 22, it can be ensured that the first terminal head 11 and the hinge groove 12 remain stable during rotation, and at the same time improve the stability of the circuit connection.

[0027] like Figure 1 and Figure 4As shown, in some embodiments, the edges of the inner walls on both the upper and lower sides of the hinge groove 12 of this utility model are provided with a barrier, the height of the isolation plate 13 is equal to the height of the barrier, and the outer surface of the hinge plate 22 abuts against the surface of the barrier, so that the connection between the hinge groove 12 and the hinge plate 22 remains in close contact. While further improving the stability of the connection, the side of the hinge groove 12 can be sealed to prevent the conductive parts from being exposed and improve safety.

[0028] like Figure 4 and Figure 5 As shown, in some embodiments, the elastic conductive sheet 14 of this invention is made of shape memory metal, thereby enabling the elastic conductive sheet 14 to deform and return to its initial state. The elastic conductive sheet 14 is set in a wave shape, and the change of the peaks and valleys of the wave shape can form a damping effect. The conductive electrode post 24 can be located at the valley of the wave of the elastic conductive sheet 14. When rotating to adjust the wiring angle, the conductive electrode post 24 will apply pressure to the peak of the elastic conductive sheet 14 due to the rotation. The pressure will deform the peak and allow the conductive electrode post 24 to pass through until a suitable angle is formed between the first terminal head 11 and the second terminal head 21. At this time, the conductive electrode post 24 will be located at the valley of the elastic conductive sheet 14, and the position of the conductive electrode post 24 will be limited under the action of the elastic pressure of the elastic conductive sheet 14 and the metal shape memory force, so that the angle between the first terminal head 11 and the second terminal head 21 will not easily change. During this process, the elastic conductive sheet 14 and the conductive electrode post 24 are always in a connected state, which can realize the adjustment of the wiring angle of the first terminal head 11 and the second terminal head 21 during the power-on process.

[0029] It should be noted that in some embodiments, the first terminal 15 and the second terminal 25 of this utility model are one or a combination of bolts, slots, and quick connectors. Using bolts for wiring can improve the stability of external cable connections, while using slots and quick connectors can improve the convenience and speed of wiring. During the production process, they can be customized according to customer needs.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the height of the top of the first terminal block 15 and the second terminal block 25 of this utility model does not exceed the height of the top of the first terminal head 11 and the second terminal head 21, respectively. When the terminal blocks are installed in a metal cabinet, limiting the height of the first terminal block 15 and the second terminal block 25 can reduce the possibility of the first terminal block 15 and the second terminal block 25 contacting the cabinet and improve the safety of use.

[0031] like Figure 1As shown, in some embodiments, an openable protective cover 3 is provided above the first terminal 15 and the second terminal 25 of this utility model. The protective cover 3 is made of insulating material, and a cable groove 31 is provided on the side of the protective cover 3 for introducing cables. After the external cable is connected to the first terminal 15 and the second terminal 25, the protective cover 3 can be used to seal and isolate the first terminal 15 and the second terminal 25 to further improve safety. A buckle or other structure can be provided at the connection between the protective cover 3 and the first terminal head 11 and the second terminal head 21 to lock the protective cover 3 after it is closed.

[0032] In summary, the rotatable terminal block for wire connection of this utility model has a hinge groove 12 at the end of the first terminal head 11, and multiple isolation plates 13 are set inside the hinge groove 12 to separate multiple independent areas. An elastic conductive plate 14 is set on the wall of the isolation plate 13 and connected to the first terminal post 15. At the same time, a hinge plate 22 is set at the end of the second terminal head 21 and is hinged inside the hinge groove 12 by a hinge shaft 23. The circuit connection is achieved by the cooperation of the conductive electrode post 24 and the elastic conductive plate 14. This improves the adaptability to complex wiring environments by rotating the wiring angle.

[0033] This invention uses a shape memory metal to prepare an elastic conductive sheet 14, and sets the elastic conductive sheet 14 in a wave shape. The conductive electrode post 24 is limited by the valley of the wave shape, thereby forming a damping structure to prevent the connection between the hinge groove 12 and the hinge plate 22 from being too flexible, thus achieving the effect of limiting the rotation angle.

[0034] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
