Description

Technical Field

[0001] This application relates to the field of terminal blocks, and more particularly to a combined terminal block. Background Art

[0002] A combined terminal block is a common electrical connection device, also known as a combined terminal or terminal block row. It is composed of multiple individual wiring components and can be used to achieve the electrical connection between a circuit board and external devices.

[0003] In the related art, a combined terminal block includes multiple wiring components. Each wiring component includes a mounting shell, an elastic pressing plate, and a conductive member. A wire is inserted through the wiring hole of the mounting shell and is pressed against the conductive plate of the conductive member by the elastic pressing plate. The pin of the conductive member passes through the bottom of the mounting shell and is connected to the circuit board to achieve the electrical connection between the wiring component and the circuit board. Among them, the pin and the circuit board need to be connected by soldering.

[0004] However, when soldering the pin to the circuit board, the molten solder easily surges upward, resulting in a certain distance between the mounting shell and the circuit board, making it difficult for the terminal block to fit tightly against the circuit board, and thus the connection stability between the terminal block and the circuit board is poor. Therefore, improvement is needed. Utility Model Content

[0017] Preferably, a connection groove is formed at one end of the button away from the elastic pressing plate.

Detailed implementation manners

[0037] The following further describes the present application in detail Figures 1-5 in conjunction with the accompanying drawings.

[0038] The embodiment of the present application discloses a combined terminal.

[0039] Referring to Figure 1 , the terminal includes a plurality of wiring components 1, and the plurality of wiring components 1 are arranged at intervals. Specifically, the wiring component 1 includes a mounting shell 11, a conductive part 12 and an elastic pressing plate 13. The mounting shell 11 is hollow, and a wiring hole 111 communicating with the inside of the mounting shell 11 is opened on one side of the mounting shell 11, and a receiving groove 112 is opened at the bottom of the mounting shell 11.

[0040] Both the conductive part 12 and the elastic pressing plate 13 are made of conductive materials. The conductive part 12 includes a conductive plate 121 and pins 122. The conductive plate 121 is arranged in a rectangular plate shape, and the conductive plate 121 is placed and installed in the mounting shell 11. The pins 122 are integrally connected to one end of the conductive plate 121 and penetrate downward through the bottom of the mounting shell 11. The elastic pressing plate 13 is arranged in a shape similar to "V" and is clamped in the mounting shell 11. One end of the elastic pressing plate 13 elastically abuts against one side of the conductive plate 121.

[0041] In practical applications, the wire passes through the mounting shell 11 from the wiring hole 111. Since one end of the elastic pressing plate 13 is elastically pressed against the conductive plate 121, the wire can be pressed between the conductive plate 121 and the elastic pressing plate 13 to achieve the pressing and fixing of the wire. The pin 122 passing downward through the bottom of the mounting shell 11 is used for soldering and fixing with the circuit board.

[0042] Among them, when soldering the connection between the pin 122 and the circuit board, the receiving groove 112 can receive the upwelling molten solder, effectively reducing the distance between the bottom of the mounting shell 11 and the circuit board, making the terminal block fit with the circuit board, thereby improving the connection stability between the terminal block and the circuit board.

[0043] Refer to Figure 2 , in some embodiments, one side of the mounting shell 11 is provided with an opening. When installing the conductive member 12 and the elastic pressing plate 13, it can be installed in the mounting shell 11 from the side with the opening of the mounting shell 11, thus facilitating the installation of the conductive member 12 and the elastic pressing plate 13.

[0044] Refer to Figure 2 and Figure 3 , in some embodiments, a plurality of wire pressing grooves 123 are formed on the conductive plate 121. The plurality of wire pressing grooves 123 are inclined and evenly spaced along the length direction of the conductive plate 121. When the wire is pressed between the conductive plate 121 and the elastic pressing plate 13, a part of the wire is located in the wire pressing grooves 123 to improve the pressing stability of the wire, thereby ensuring the working stability of the wiring assembly 1.

[0045] In some embodiments, the conductive member 12 further includes a mounting plate 124. The mounting plate 124 is integrally connected to the upper side of the conductive plate 121 and is clamped in the mounting shell 11. At the same time, the lower side of the conductive plate 121 abuts against the mounting shell 11 to achieve the detachable connection of the conductive member 12, and the structure is simple, facilitating the installation and disassembly of the conductive member 12. Moreover, the mounting plate 124 can be in contact with the wire for conduction to ensure the conduction stability between the conductive member 12 and the wire, further ensuring the working stability of the wiring assembly 1.

[0046] Refer to Figure 2 and Figure 4, in some embodiments, the wiring assembly 1 further includes a button 14. The mounting shell 11 is provided with a limiting groove 113 on one side of the wiring hole 111. The limiting groove 113 communicates with the inside of the mounting shell 11. The button 14 is limited in the limiting groove 113, and one end of the button 14 abuts against the elastic pressing plate 13, and the other end protrudes from the mounting shell 11. By pressing the button 14, the button 14 presses the elastic pressing plate 13, and the elastic pressing plate 13 deforms and separates from the conductive plate 121. At this time, the wire is passed between the conductive plate 121 and the elastic pressing plate 13, and then the button 14 is released, and the elastic pressing plate 13 rebounds to realize the pressing of the wire, so as to facilitate the installation of the wire.

[0047] In some embodiments, a connection groove 141 is formed at one end of the button 14 away from the elastic pressing plate 13. The connection groove 141 can cooperate with a tool (such as a flat screwdriver, etc.) to facilitate pressing the elastic pressing plate 13 through the button 14, thereby further facilitating the installation of the wire.

[0048] In some embodiments, a limiting protrusion 142 protrudes from one end of the button 14 close to the elastic pressing plate 13. The limiting protrusion 142 abuts against the elastic pressing plate 13, and at the same time, the limiting protrusion 142 abuts against the inner side of the mounting shell 11 under the action of the elastic pressing plate 13, so that the button 14 can be limited between the mounting shell 11 and the elastic pressing plate 13, thereby minimizing the risk of the button 14 falling out of the limiting groove 113 to ensure the stability of the button 14 during operation.

[0049] In some embodiments, a test groove 114 is formed at the top of the mounting shell 11. The test groove 114 communicates with the inside of the mounting shell 11, and a part of the elastic pressing plate 13 is located in the test groove 114. The elastic pressing plate 13 also has conductivity. Just by contacting the wire with the elastic pressing plate 13 through the test groove 114, it is possible to test whether the corresponding wiring assembly 1 can work properly.

[0050] In some embodiments, a plurality of insertion posts 115 protrude from one side of the mounting shell 11 along its circumferential direction at the opening. A plurality of insertion holes 116 are formed at the corresponding positions of the other side of the mounting shell 11 for the plurality of insertion posts 115. The insertion posts 115 of one mounting shell 11 are inserted into the insertion holes 116 of an adjacent mounting shell 11 to realize the connection between two adjacent mounting shells 11, that is, to realize the connection between two wiring assemblies 1, so as to facilitate the installation and disassembly between the two wiring assemblies 1, and thus facilitate the overall assembly of the terminal block.

[0051] Referring to Figure 5 , it should be noted that the opening of the mounting shell 11 at one end is not closed. Therefore, the terminal block further includes an end cover 2. The end cover 2 cooperates with the plurality of insertion posts 115 of the mounting shell 11 to realize their installation to ensure that the openings of the mounting shells 11 are in a closed state.

[0052] In some embodiments, two adjacent pins 122 are arranged in a staggered manner to avoid the mutual influence of the conductive work between two adjacent wiring components 1 as much as possible, thereby improving the stability of the operation of the terminal block.

[0053] The implementation principle of this embodiment is as follows: In practical applications, the wire passes through the mounting shell 11 from the wiring hole 111. Since one end of the elastic pressing plate 13 is elastically pressed against the conductive plate 121, the wire can be pressed between the conductive plate 121 and the elastic pressing plate 13 to achieve the pressing and fixing of the wire. The pin 122 passing downward through the bottom of the mounting shell 11 is used for soldering and fixing with the circuit board.

[0054] Among them, when soldering the connection between the pin 122 and the circuit board, the receiving groove 112 can receive the upwelling molten solder, effectively reducing the distance between the bottom of the mounting shell 11 and the circuit board, enabling the terminal block to fit with the circuit board, thereby improving the connection stability between the terminal block and the circuit board.

[0055] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
