Description

Technical Field

[0001] This utility model relates to the field of electrical connection element technology, specifically to a novel terminal block. Background Technology

[0002] Terminal blocks are essential components for achieving electrical connections, primarily used for transmitting current or signals. With the rapid development of the electronics industry, the usage of terminal blocks is gradually increasing, and the types involved are also becoming more diverse.

[0003] For example, Chinese utility model patent CN220731831U, "A Quick-Connect Miniature Terminal Block," discloses a terminal block with a base containing a button, a connecting spring, and a conductor clip. One end of the conductor clip has a spring mounting shaft for the connecting spring to nest within. In use, the button is pressed to its limit, and the wire is directly inserted into the terminal. Releasing the button causes the connecting spring to automatically return to its original position, clamping the wire and conductor clip securely. However, this terminal block only has one connecting spring, which is prone to deformation due to uneven stress and insufficient support, leading to unstable wiring within the terminal block.

[0004] Therefore, further improvements are needed to the structure of the wiring terminals. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a new type of terminal block with a spring that is not easily deformed and has stable wiring, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a novel wiring terminal, comprising:

[0007] An insulating base having at least one wiring cavity inside;

[0008] The fluid carrier is disposed within the wiring cavity of the insulating base;

[0009] Its characteristic is that it further includes:

[0010] At least two pressing elements are disposed on the insulating base;

[0011] A spring-loaded structure is disposed within the wiring cavity of the insulating base;

[0012] A limiting mechanism is provided within the wiring cavity of the insulating base;

[0013] The spring-loaded structure has the following characteristics:

[0014] The first spring is configured to withstand the compression of the corresponding pressing member and to clamp the corresponding first wire;

[0015] The second spring is symmetrically arranged to the left and right of the first spring and is subjected to force on each other. The second spring is configured to withstand the compression of the corresponding pressing member and to clamp the corresponding second wire.

[0016] The limiting mechanism limits the deformation stroke of the first and second spring pieces respectively.

[0017] To achieve uniform force distribution, preferably, both the first and second springs include:

[0018] The vertical sections of the two spring clips abut against each other to exert force on each other;

[0019] Alternatively, both the first and second springs may include:

[0020] The vertical section is configured to abut against each other to exert force on each other; the inclined section is configured to bear the pressing force of the pressing member.

[0021] A connecting segment, one end of which is connected to the top of the vertical segment, and the other end of which is connected to the inclined segment;

[0022] The vertical sections of the first and second spring pieces abut against each other. Inclined sections are located on both sides of the vertical sections and slope downwards away from the vertical sections. As the pressing component applies downward pressure, the vertical sections of the first and second spring pieces abut against and support each other, thereby ensuring that the spring pieces are subjected to uniform force and are not prone to deformation.

[0023] To facilitate wire installation, preferably, the bottom of the pressing member is configured to abut against the corresponding inclined segment after being pressed, and each inclined segment can move synchronously away from or towards the corresponding vertical segment. The inclined segment of the spring can adjust its closing amplitude under the action of the pressing member, thereby providing continuous pressure during wiring, ensuring tight contact between the wire and the terminal block, and preventing loosening of the wire due to external factors, thus affecting the stability of the connection. Furthermore, the spring can accommodate wires of different diameters, thereby ensuring the reliability of the connection.

[0024] For ease of installation and processing, it is preferable that the first and second springs are integrally formed. This integral forming of the first and second springs reduces the complexity of the production process.

[0025] To facilitate the fixing of the spring clips, preferably, the first and second spring clips are independently arranged and spaced apart, and integrally formed with the fluid carrier. The integral forming of the first and second spring clips with the fluid carrier using a mold improves the robustness of the spring clip structure, thereby preventing detachment or displacement due to repeated insertion and removal, which would affect its use.

[0026] Another implementation method is as follows: the first and second springs are connected by a connector, which mates with the fluid-carrying material. The fluid-carrying material has grooves for the connector to mate with, thereby fixing the first and second springs to the fluid-carrying material and ensuring the robustness and stability of the spring structure installation.

[0027] To limit the movement of the spring clip, preferably, the limiting mechanism includes:

[0028] The first limiting part is disposed on the fluid carrier and is locked on both sides of the vertical section of the first and second spring pieces near the upper end, so as to restrict the left and right movement of the corresponding spring pieces.

[0029] The second limiting part is disposed below the first limiting part and is locked on both sides of the vertical section of the first and second spring pieces near the lower end, so as to restrict the left and right movement of the corresponding spring pieces.

[0030] The third limiting part is disposed on the fluid-carrying surface and located on the movement trajectory of the corresponding side spring sheet after deformation under pressure. The first limiting part is engaged on both sides of the vertical section near the upper end, and the second limiting part is engaged on both sides of the vertical section near the lower end. These two parts cooperate to restrict the left-right movement of the first and second spring sheets, thereby maintaining the stability of the spring sheets in the left-right direction. The third limiting part can limit the closing amplitude of the corresponding side spring sheet, thereby preventing the first or second spring sheet from deforming due to excessive closing amplitude.

[0031] Furthermore, the limiting mechanism also includes a fourth limiting part. Slots for inserting the fourth limiting part are provided on the first spring piece near its lower vertical end and on the second spring piece near its lower vertical end. The fourth limiting part restricts the vertical movement distance of the first and second spring pieces. The thickness of the fourth limiting part is less than the height of the slot. When the pressing element is pressed, the first and second spring pieces move downwards a specified distance under the limiting action of the fourth limiting part, thus preventing plastic deformation of the spring pieces due to excessive downward movement. When the pressing force is removed, the first and second spring pieces move upwards a specified distance under the limiting action of the fourth limiting part, thus ensuring that the spring pieces return to their designated positions.

[0032] For ease of operation, preferably, each of the pressing components includes a pressing portion exposed above the insulating base, with the force-bearing surface located on the pressing portion. Each pressing portion extends downward to form an extension arm capable of applying pressure to the corresponding inclined section. The pressing portion being exposed above the insulating base facilitates the use of external tools to perform a pressing action, thereby causing the extension arm to move downward synchronously and apply force to the spring located below, thus achieving the closing action of the spring and facilitating the insertion and removal of wires.

[0033] For ease of installation, preferably, the insulating base has:

[0034] Both inlet ports are connected to the same wiring cavity simultaneously; and,

[0035] A cable outlet is connected to the wiring cavity. The electrical connector in this application uses a two-in-one-out wiring configuration; therefore, the two inlets at the top and the one outlet at the bottom of the wiring cavity meet the wiring requirements of the electrical connector.

[0036] Compared with the prior art, the advantages of this utility model are as follows: by setting a spring sheet structure in the wiring cavity, the spring sheet structure includes a first spring sheet and a second spring sheet that are symmetrically arranged on the left and right and subjected to force on each other, the first spring sheet and the second spring sheet can perform a closing action under the pressing action of the pressing member, thereby realizing the insertion and removal of the wire. The first spring sheet and the second spring sheet are subjected to uniform force and are not easily deformed. At the same time, the product wiring is stable and has a strong current carrying capacity. Attached Figure Description

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0049] like Figures 1-6 The diagram shows the preferred embodiment of this utility model. The novel terminal block includes an insulating base 1, within which five wiring cavities 11 are provided. Each wiring cavity 11 contains an insulating base 1, and each insulating base 1 has two pressing members 3. Each wiring cavity 11 also contains a spring-loaded structure 4 and a limiting mechanism 5. (See reference...) Figure 6 The spring structure 4 has a first spring 41 and a second spring 42. The first spring 41 is configured to withstand the compression of the corresponding pressing member 3 and to clamp the corresponding first wire. The second spring 42 is symmetrically arranged with the first spring 41 and is subjected to force from each other. The second spring 42 is configured to withstand the compression of the corresponding pressing member 3 and to clamp the corresponding second wire. The limiting mechanism 5 limits the deformation stroke of the first spring 41 and the second spring 42 respectively.

[0050] Currently, existing terminal blocks typically use a single spring. During use, single-spring products suffer from unstable wiring and are prone to deformation. Therefore, referencing... Figure 6 The spring structure 4 in this application includes a first spring 41 and a second spring 42. Both the first spring 41 and the second spring 42 include a vertical section 43, an inclined section 45 configured to bear the pressing force of the pressing member 3, and a connecting section 44. One end of the connecting section 44 is connected to the top of the vertical section 43, and the other end is connected to the inclined section 45. During the downward pressure applied by the pressing member 3, the vertical sections 43 of the first spring 41 and the second spring 42 abut against and support each other to achieve mutual force application, thereby ensuring that the spring structure 4 is subjected to uniform force and is not prone to deformation.

[0051] refer to Figures 3 to 5The bottom of the pressing member 3 is configured to abut against the corresponding inclined section 45 after the pressing member 3 is pressed. Each inclined section 45 can move synchronously in the direction away from or towards the corresponding vertical section 43. The inclined section 45 of the spring structure 4 can adjust the closing amplitude under the action of the pressing member 3, so as to provide continuous pressure during the wiring process, thereby ensuring tight contact between the wire and the terminal, and avoiding the loosening of the wire due to external factors, which would affect the stability of the connection. In addition, the spring can adapt to wires of different diameters, thereby ensuring the reliability of the connection.

[0052] Under the pressing force of the pressing member 3, the spring structure 4 will undergo elastic deformation. To ensure that the spring structure 4 is always in the correct installation position, refer to... Figures 3 to 5 In this embodiment, a limiting mechanism 5 is provided inside the terminal block. The limiting mechanism 5 includes a first limiting part 51, a second limiting part 52, and a third limiting part 53. The first limiting part 51 is disposed on the fluid carrier 2 and is engaged on both sides of the upper end of the vertical section 43 of the first spring piece 41 and the second spring piece 42. The second limiting part 52 is disposed below the first limiting part 51 and is engaged on both sides of the lower end of the vertical section 43 of the first spring piece 41 and the second spring piece 42. The third limiting part 53 is disposed on the fluid carrier 2 and is located on the movement trajectory of the corresponding side spring piece after being deformed by pressure. The first limiting part 51 and the second limiting part 52 cooperate with each other to restrict the left and right movement of the first spring piece 41 and the second spring piece 42, thereby maintaining the stability of the spring piece in the left and right direction. The third limiting part 53 can limit the closing amplitude of the corresponding side spring piece, thereby preventing the first spring piece 41 or the second spring piece 42 from deforming due to excessive closing amplitude. In addition, the limiting mechanism 5 also includes a fourth limiting part 54. The vertical section 43 of the first spring piece 41 and the second spring piece 42 is provided with a slot 46 near the lower end for the fourth limiting part 54 to be inserted. The fourth limiting part 54 can limit the vertical movement distance of the first spring piece 41 and the second spring piece 42. In this embodiment, the thickness of the fourth limiting part 54 is less than the height of the slot 46. When the pressing member 3 is pressed, the first spring piece 41 and the second spring piece 42 move downward a specified distance under the limiting action of the fourth limiting part 54, thereby avoiding plastic deformation of the spring pieces due to excessive downward movement. When the pressing force is removed, the first spring piece 41 and the second spring piece 42 move upward a specified distance under the limiting action of the fourth limiting part 54, thereby ensuring that the spring pieces are reset to the specified position.

[0053] refer to Figure 1 and Figure 2 as well as Figure 4 and Figure 5Each pressing component 3 includes a pressing part 31 exposed above the insulating base 1. The force-bearing surface is located on the pressing part 31. Each pressing part 31 extends downward to form an extension arm 32 that can apply pressure to the corresponding inclined section 45. The pressing part 31 is exposed above the insulating base 1, which makes it easy for external tools to perform the pressing action, thereby driving the extension arm 32 to move down synchronously and apply force to the spring piece located below, thereby realizing the closing action of the spring piece, which facilitates the insertion and removal of wires.

[0054] The electrical connector in this application uses a two-in-one-out wiring method, see reference. Figure 1 Therefore, the insulating base 1 in this embodiment has two inlet ports 12 and one outlet port 13 that are simultaneously connected to the same wiring cavity 11. The two inlet ports 12 and one outlet port 13 can meet the wiring requirements of the electrical connector.

[0055] The working principle of the wiring terminals in this embodiment is as follows: (Refer to...) Figure 4 When the spring contact structure 4 of the terminal block is in the open state, the operator uses an external tool to press down the pressing part 31. At this time, the inclined sections 45 of the first spring contact 41 and the second spring contact 42 close together under the action of the extension arm 32 until the inclined sections 45 abut against the third limiting part 53 (see reference). Figure 5 At this time, the first wire and the second wire can be inserted into the wiring cavity 11 or pulled out from the wiring cavity 11. After the operation is completed, stop applying force to the pressing part 31. The inclined section 45 of the first spring 41 and the second spring 42 rebounds until the slot 46 of the vertical section 43 abuts against the fourth limiting part 54 and then stops moving.

[0056] Example 2:

[0057] refer to Figure 7 The structure of the terminal block in this embodiment is basically the same as that in embodiment 1, except that the limiting mechanism 5 only includes the first limiting part 51, and the first spring 41 and the second spring 42 are integrally formed. In this embodiment, the vertical section 43 of the first spring 41 and the second spring 42 are preferably connected in a "U" shape. The vertical section 43 is designed as a "U" shape to distribute the force, so that the spring structure 4 is more evenly stressed. At the same time, the spring structure 4 can be installed on the fluid carrier 2 as a whole during the installation process, which is convenient.

[0058] Example 3:

[0059] Meal card Figure 8 and Figure 9The structure of the terminal block in this embodiment is basically the same as that in embodiment 1, except that: the limiting mechanism 5 only includes the first limiting part 51, and the first spring 41 and the second spring 42 are independent of each other and spaced apart. The first spring 41, the second spring 42 and the fluid carrier 2 are integrally formed by the mold, and the vertical sections 43 of the first spring 41 and the second spring 42 are fixed to the fluid carrier 2 by riveting or other means to ensure the firmness and stability of the spring structure 4.

[0060] Example 4:

[0061] refer to Figure 10 The structure of the terminal block in this embodiment is basically the same as that in embodiment 1, except that the limiting mechanism 5 only includes the first limiting part 51, and the first spring 41 and the second spring 42 are connected by a connector. In this embodiment, the preferred connector is interference-fitted with the groove on the fluid carrier 2, so that the first spring 41 and the second spring 42 are fixed on the fluid carrier 2, ensuring the firmness and stability of the spring structure 4.
