[0038] The following is combined with Figures 1-5 This application is described in further detail.

[0039] An embodiment of the present application discloses a wiring terminal.

[0040] Reference Figure 1 The terminal block includes a mounting shell 1, a conductive spring 2, a pin 3 and a connecting knob 4. A mounting groove 11 and a wiring hole 12 are provided on one side of the mounting shell 1. The mounting groove 11 is connected to the wiring hole 12, and the wiring hole 12 extends to the other side of the mounting shell 1. At the same time, a rotating column 13 is protruded from the bottom wall of the mounting shell 1 located in the mounting groove 11.

[0041] Reference Figure 1 and Figure 2 The conductive spring piece 2 has conductivity and elasticity, wherein the conductive spring piece 2 includes a first abutting portion 21, a second abutting portion 22 and a connecting portion 23, and the two ends of the connecting portion 23 are respectively integrally connected to the upper end of the first abutting portion 21 and the upper end of the second abutting portion 22, and the upper end of the first abutting portion 21 is rotated between the rotating column 13 and the mounting shell 1.

[0042] Pin 3 is snap-fitted to the lower end of mounting slot 11, with the lower end of pin 3 protruding from mounting housing 1. The lower ends of first abutting portion 21 and second abutting portion 22 elastically abut against the upper end of pin 3. Connecting knob 4 is rotatably connected to one end of mounting slot 11 and protruding from mounting housing 1 at the other end. Connecting knob 4 abuts against the upper side of connecting portion 23 to restrict rotation of first abutting portion 21.

[0043] In practical applications, in the initial state, the lower end of the first abutting portion 21 and the lower end of the second abutting portion 22 abut against the upper end of the pin 3, the connecting knob 4 is horizontally arranged and abuts against the upper side of the connecting portion 23. When connecting a wire, rotate the connecting knob 4 upward, the connecting knob 4 moves away from the connecting portion 23, so that the connecting knob 4 releases the abutment against the connecting portion 23, and then insert the wire through the wiring hole 12. The wire drives the first abutting portion 21 to rotate, and under the elastic deformation of the first abutting portion 21, the second abutting portion 22 and the connecting portion 23, the wire is located between the conductive elastic sheet 2 and the pin 3. At this time, the first abutting portion 21 and the second abutting portion 22 press the wire tightly against the upper end of the pin 3. Then rotate the connecting knob 4 downward so that the connecting knob 4 abuts against the connecting portion 23 to limit the rotation of the first abutting portion 21 to achieve the connection of the wire. Among them, since the first abutting portion 21 and the second abutting portion 22 of the conductive elastic sheet 2 press the wire at the same time, and the connecting knob 4 can limit the rotation of the first abutting portion 21, the stability of the wire connection is effectively improved.

[0044] Refer to Figure 2 and Figure 3 , in some embodiments, one end of the connecting knob 4 located in the mounting groove 11 protrudes to form an abutting block 41, and the abutting block 41 is used to abut against one end of the connecting portion 23 close to the second abutting portion 22. Specifically, when the connecting knob 4 is rotated upward, the abutting block 41 of the connecting knob 4 approaches the connecting portion 23. During the process of inserting the wire, since the first abutting portion 21 rotates, the abutting block 41 can abut against the connecting portion 23 to limit the position of the conductive elastic sheet 2, and try to avoid excessive deformation of the first abutting portion 21, the second abutting portion 22 and the connecting portion 23, resulting in bending damage of the conductive elastic sheet 2 and reduction of elastic ability, thereby improving the service life of the conductive elastic sheet 2.

[0045] In some embodiments, a positioning groove 24 is formed at one end of the connecting portion 23 close to the second abutting portion 22. During the process of the abutting block 41 abutting against the connecting portion 23, the positioning groove 24 cooperates with the abutting block 41 to achieve the positioning abutment of the abutting block 41, making the deformation of the first abutting portion 21, the second abutting portion 22 and the connecting portion 23 more stable.

[0046] Refer to Figure 2 , in some embodiments, the guiding elastic sheet further includes a strengthening portion 25. The strengthening portion 25 is bent, and both ends of the strengthening portion 25 are integrally connected to the second abutting portion 22 and the connecting portion 23 respectively, making the connection between the second abutting portion 22 and the connecting portion 23 more stable, and improving the overall structural strength and elastic deformation ability of the conductive elastic sheet 2, making the operation of the wiring terminal more stable.

[0047] In some embodiments, a material-reducing groove 26 is provided at the second abutting portion 22 and the reinforcing portion 25 to reduce the production cost of the conductive elastic sheet 2, thereby reducing the overall production cost of the terminal block. Moreover, the material-reducing groove 26 can provide clearance for the rotation of the connecting knob 4, and can avoid the normal rotation operation of the connecting knob 4 as much as possible.

[0048] Refer to Figure 4 , in some embodiments, on both sides of one end of the connecting knob 4 protruding from the mounting shell 1, a plurality of anti-slip protrusions 42 are formed protruding. The plurality of anti-slip protrusions 42 are arranged at intervals along the length direction of the connecting knob 4. When a staff member pinches one end of the connecting knob 4 protruding from the mounting shell 1 to make the connecting knob 4 rotate, the plurality of anti-slip protrusions 42 can effectively increase the friction force, making the process of rotating the connecting knob 4 more stable.

[0049] In some embodiments, on both sides of one end of the connecting knob 4 protruding from the mounting shell 1, force-applying grooves 43 are provided, so as to facilitate the staff member to reach into the force-applying grooves 43 to apply force to rotate the connecting knob 4.

[0050] In some embodiments, the mounting shell 1 protrudes to form a limiting block 14. The limiting block 14 is arranged in a rectangular block shape and is located in the force-applying groove 43. When the limiting block 14 abuts against the groove wall of the force-applying groove 43, the rotation of the connecting knob 4 can be restricted to improve the working stability of the terminal block. At the same time, a first chamfer 141 is provided on the upper side of the limiting block 14, and a second chamfer 142 is provided on the lower side of the limiting block 14. Under the limitation of the first chamfer 141 and the second chamfer 142, force is applied to rotate the connecting knob 4, so as to facilitate the limiting block 14 to extend into and out of the force-applying groove 43, thereby facilitating the normal operation of the connecting knob 4.

[0051] The implementation principle of this embodiment is as follows: In practical applications, in the initial state, the lower end of the first abutting portion 21 and the lower end of the second abutting portion 22 abut against the upper end of the pin 3, the connecting knob 4 is horizontally arranged and abuts against the upper side of the connecting portion 23. When connecting a wire, rotate the connecting knob 4 upward, the connecting knob 4 moves away from the connecting portion 23, so that the connecting knob 4 releases the abutment against the connecting portion 23, and then insert the wire through the wiring hole 12. The wire drives the first abutting portion 21 to rotate, and under the elastic deformation of the first abutting portion 21, the second abutting portion 22 and the connecting portion 23, the wire is located between the conductive elastic sheet 2 and the pin 3. At this time, the first abutting portion 21 and the second abutting portion 22 press the wire against the upper end of the pin 3. Then rotate the connecting knob 4 downward so that the connecting knob 4 abuts against the connecting portion 23 to restrict the rotation of the first abutting portion 21 to achieve the connection of the wire. Among them, since the first abutting portion 21 and the second abutting portion 22 of the conductive elastic sheet 2 press the wire at the same time, and the connecting knob 4 can restrict the rotation of the first abutting portion 21, the stability of wire connection is effectively improved.

[0052] The embodiments of the present application also disclose a connector.

[0053] Referring to Figure 5 , the connector includes a plurality of the terminal blocks described in the above embodiments, and two adjacent mounting cases 1 are detachably connected. The detachable connection method can be but is not limited to snap connection, plug connection, bolt connection, etc., and the present application does not limit it.

[0054] All of the above are the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
