[0032] Example

[0033] Combination Figures 1 to 8The present embodiment provides a connection terminal, including a plastic shell body 1 and a clamping spring 2. The plastic shell body 1 is formed by assembling and docking a plurality of shell units 11. The shell unit 11 is provided with a window 12 connected to the internal wire insertion channel, and the window 12 is used to allow an external wire to enter the wire insertion channel to be clamped by the clamping spring 2. A reinforcement section 13 is correspondingly provided on one side of the window 12, and the reinforcement section 13 is located at the junction of two adjacent shell units 11 to prevent the wire from acting on the window 12 and thus breaking the two shell units 11 apart.

[0034] The connecting terminal mentioned above is provided with a reinforcing section 13 in the window 12 of the shell unit 11, and the reinforcing section 13 is located at the junction of two adjacent shells, so as to reduce the force of the wire affecting the window 12, thereby preventing the two shell units 11 from loosening or breaking apart due to the action of the wire, thereby improving the stability and safety of the connecting terminal and enhancing the stability of the wire insertion channel. Through the provision of the reinforcing section 13, the adverse effects that may be caused by the external wire are effectively prevented, ensuring the normal use of the connecting terminal, especially in a wiring environment of violent plugging, the effect is particularly significant.

[0035] like Figure 2 and Figure 6 As shown, in this embodiment, the reinforcing section 13 is configured as a side wall portion extending in the longitudinal direction, and the side wall portion is integrally formed on the outer wall of the window 12. This helps to further consolidate the structure of the entire housing, and by extending the reinforcing section 13 in the longitudinal direction of the terminal and integrating it with the outer wall of the window 12, it can provide stronger support and stability, effectively avoiding the adverse effects of the external force generated when the wire is inserted into the channel on the terminal structure, ensuring that the terminal remains stable during use, thereby improving the reliability and safety of the connection terminal.

[0036] Furthermore, the reinforcing section 13 is arranged on the right side wall facing the window 12, and the outer edge 14 of the window 12 on the left side is relatively recessed relative to the reinforcing section 13 on the right side. In order to optimize the external structure of the entire connection terminal, by forming a recess on the outer edge 14 of the window 12, the wire can be more naturally contacted with the reinforcing section 13 when inserted, without being interfered by the protruding part. At the same time, the reinforcing section 13 is arranged on the right side wall of the window 12 opposite to each other, which can provide more support and stability and prevent the connection terminal from being affected by external factors.

[0037] like Figures 2 to 4As shown, in this embodiment, the adjacent housing units 11 are mechanically coupled to each other in a lateral assembly manner, so that the reinforcing section 13 is smoothly embedded in the inner concave outer edge 14 of the adjacent housing unit 11. The adjacent housing units 11 are laterally butted and embedded with each other, so that the reinforcing section 13 can be seamlessly and smoothly combined with the inner concave outer edge 14 of the adjacent housing unit 11, further consolidating the structural stability and consistency of the appearance of the connection terminal, and the coupling method helps to ensure the firm assembly of the connection components and effectively prevent the loosening or instability of the terminal structure due to external forces during use.

[0038] Specifically, a plurality of mounting posts 15 are provided in one of the housing units 11, and mounting holes 16 matching the mounting posts 15 are provided in another adjacent housing unit 11, and a mushroom head structure is provided at the end of the mounting post 15. The mushroom head structure of the mounting post 15 is used to achieve alignment during the assembly and disassembly process between the housing units 11, and provides a more stable fixing method for the connection. By cooperating with the mounting holes 16 of the adjacent housing units 11, accurate alignment and firm connection between the housing units 11 are ensured, which helps to ensure the stability and reliability of the terminal structure and improve the durability and use strength of the connector.

[0039] Preferably, a plurality of mounting columns 15 are provided correspondingly on the upper and lower wall edges of the shell unit 11, and the mounting columns 15 are moved forward to the rear wall edge of the shell unit 11, so that the rear wall of the shell unit 11 can be made as thin as possible, and the layout of the mounting columns 15 is more compact, thereby achieving stable splicing between them.

[0040] like Figures 6 to 8 As shown, in this embodiment, the clamping spring 2 includes a spring member 21 and a busbar 22 forming a clamping portion, and the housing unit 11 is provided with an operating handle 3 for controlling the spring member 21 to open or close the clamping portion, and a pivoting column 17 axially connected to the operating handle 3, and at least two mounting columns 15 are arranged closely on the outer peripheral side of the operating handle 3. The clamping spring 2 is controlled by the operating handle 3 and the pivoting column 17, and the close arrangement of multiple mounting columns 15 helps to enhance the connection stability around the operating handle 3, which is convenient for the user to frequently pull the operation. Obviously, the end of the pivoting column 17 is provided with a mushroom head structure for tightly installing the operating handle 3.

[0041] In this embodiment, the operating handle 3 is provided with a pressing portion 31 for limiting the clamping part to a closed state in the initial position, and a lifting portion 32 for switching the clamping part to an open state in the operating position. The pressing portion 31 is formed at the lower end of the operating handle 3, and the lifting portion 32 is an axially extending horizontal hook, and one end of the spring member 21 extends between the pressing portion 31 and the lifting portion 32. Among them, after pulling up the operating handle 3, the lifting portion 32 hooks up the spring member 21, correspondingly moving the spring member 21 relatively away from the bus 22, and the clamping part is opened at this time. After pressing down the operating handle 3, the pressing portion 31 presses down and closes the spring member 21, correspondingly moving the spring member 21 relatively close to the bus 22, and the clamping part is closed at this time. Therefore, by pressing and lifting the operating handle 3, the user can quickly switch the state of the clamping part and adjust the connection terminal to open or close accordingly.

[0042] like Figure 4 As shown, in this embodiment, the housing unit 11 is provided with a U-shaped detection port 18 that penetrates laterally, and the detection port 18 is connected to the internal spring member 21. In a more convenient way, the through U-shaped detection port 18 can be maximized in the horizontal direction, which is conducive to the external test pen to perform internal electrical testing. This U-shaped detection port 18 allows the user to insert a tool or a probe pen to detect the state or other parameters of the spring member 21 inside the connector.

[0043] In this embodiment, a clamping portion (not shown) adapted for plugging in the busbar 22 to extend the solder pin is provided on the bottom wall of the housing unit 11. The clamping portion is formed on the bottom wall to reduce interference with the wire entering the plug-in channel. This configuration can provide a plug-in installation position for the busbar 22, and reduce interference with the wire when it is inserted into the plug-in channel by setting the clamping portion. The clamping portion is provided on the inner wall, and the clamping limit of the busbar 22 by the clamping convex of the inner wall is cancelled, which greatly extends the insertion length of the wire in the plug-in channel and improves the effectiveness of the wiring connection.

[0044] like Figure 7 and Figure 8 As shown, in this embodiment, a side cover 19 is provided on the far right side for sealing the housing unit 11, and the side cover 19 is provided with a mounting hole adapted to the mounting column 15. The side of the housing unit 11 is effectively sealed by the provision of the side cover 19, and the side cover 19 is firmly fixed to the housing unit 11 to protect the internal structural components.

[0045] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
