It is easy for the spring sheet and the conductor to clamp the insulation layer of the wire, resulting in poor contact between the connector of the wire and the conductor, and unreliable contact between the spring sheet and the connector of the wire, which brings inconvenience to the wiring operation and affects the wiring efficiency.

DETAILED DESCRIPTION
[0035] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.
[0036] Embodiment 1:
[0037] refer to Figures 1 to 6 A terminal block includes an insulating shell 1, two limiting structures 2, two interference structures, a conductive frame 8, two springs 9 and two driving keys 15. An assembly cavity 101 is provided on one side of the insulating shell 1. The opening side of the assembly cavity 101 is the assembly side of the terminal block. Both sides of the insulating shell 1 are provided with wiring holes 102. The limiting structures 2, the interference structures, the springs 9 and the driving keys 15 are all distributed at positions corresponding to the wiring holes 102 of the insulating shell 1. A threading opening 103 for the wire to pass through is formed between the wiring hole 102 and the assembly cavity 101. Preferably, the threading opening 103 is composed of two vertical side walls 17 and a connecting wall 18. The two vertical side walls 17 are vertically distributed on both sides of the connecting wall 18. The two vertical side walls 17 and the connecting wall 18 are formed together when the threading opening 103 of the insulating shell 1 is formed, so that the threading opening 103 is a square opening.
[0038] The two limiting structures 2 are symmetrically distributed on both sides of the assembly cavity 101. The limiting structure 2 includes a baffle portion 21 and a supporting portion 22. The inner side wall of the bottom of the baffle portion 21 is provided with a connecting plate 11. The connecting plate 11 is fixedly connected to the inner wall of the assembly cavity 101, so that a swing space 4 is formed between the inner side wall of the baffle portion 21 and the inner wall of the assembly cavity 101. A first positioning space 3 is formed between the edge portion of the baffle portion 21 and the inner wall of the corresponding assembly cavity 101, and the first positioning space 3 is L-shaped.
[0039] The two ends of the conductive frame 8 are bent to form abutment sections 801, and the abutment sections 801 and the conductive frame 8 connected thereto are both L-shaped. The two ends of the conductive frame 8 are respectively inserted into the two first positioning spaces 3, and the inner wall of the assembly cavity 101 is concavely formed with a docking groove 16. The two first positioning spaces 3 are respectively adapted to the two sides of the docking groove 16, and the docking groove 16 is concavely matched with the insertion side of the conductive frame 8, so that the conductive frame 8 is installed in the assembly cavity 101. The abutment section 801 is the clamping side of the conductive frame 8, and the abutment section 801 corresponds to the swing space 4. Preferably, the bottom of the connecting plate 11 is convexly formed with a positioning block 12, and the conductive frame 8 is provided with a positioning groove 803 for the positioning block 12 to be inserted, so as to improve the connection stability of the conductive frame 8 in the assembly cavity 101.
[0040] The connecting plate 11 is provided with an extension arm 13, which extends toward the inner side of the assembly cavity 101 and is fixedly connected to the inner wall of the assembly cavity 101, and an assembly space 14 is formed between the baffle portion 21 and the extension arm 13. The supporting portion 22 is composed of a shaft portion and an extension portion connected to each other, and a second positioning space 5 is formed between the shaft portion of the supporting portion 22 and the inner wall of the inner wall of the assembly cavity 101 corresponding thereto, and the second positioning space 5 is U-shaped.
[0041] A wire opening wall 105 is provided at a position of the insulating shell 1 corresponding to the wire opening 103. The wire opening wall 105 is arranged adjacent to the connecting wall 18. The width of the baffle portion 21 is smaller than the inner diameter of the wire opening 103. The baffle portion 21 and the wire opening wall 105 are arranged at intervals to form an observation port 7 therebetween. The observation port 7 extends along the width direction of the baffle portion 21, and the observation port 7 is connected to the first positioning space 3, so that the wiring personnel can observe the condition of the wire passing through the wire opening 103 more comprehensively through the observation port 7 when inserting the wire into the wire opening 103.
[0042] The spring piece 9 includes a clamping section 91, a centering section 92 and a positioning section 93 which are connected to each other. The interference structure includes a baffle interference portion 62. The baffle interference portion 62 is integrally formed at the top end of the baffle portion 21. The baffle interference portion 62 is an inclined block or a convex point. The distance D1 between the baffle interference portion 62 and the wire opening wall 105 is smaller than the thickness D2 of the abutting section 801, so as to ensure that the distance between the baffle portion 21 and the wire opening wall 105 at least in one place is smaller than the thickness of the abutting section 801, so that the clamping section 91 cannot pass through the observation port 7. Preferably, the baffle interference portion 62 is an inclined block, and the top surface of the inclined block is an inclined surface 10. The observation port 7 formed between the inclined surface 10 and the inner wall of the inner wall of the corresponding assembly cavity 101 is V-shaped. The minimum gap between the inclined surface 10 and the wire opening wall 105 is located at a position where the observation port 7 is away from the abutting section 801. Please refer to Figure 4 There is another embodiment of the baffle interference portion 62, where the minimum gap between the inclined surface 10 and its line opening wall 105 is located at a position of the observation port 7 close to the abutment section 801.
[0043] When the spring piece 9 is bent and assembled into the assembly cavity 101, pressure is applied to the spring piece 9 to bring the clamping section 91 and the positioning section 93 closer together, so that the spring piece 9 is assembled into the assembly cavity 101 in a concave manner. In this process, the centering section 92 is installed in the second positioning space 5. Under the restriction of the extension portion of the support portion 22 and the inner wall of the corresponding assembly cavity 101, the end of the positioning section 93 abuts against the positioning portion 802, and the observation port 7 formed between the baffle portion 21 and the wire port wall 105 interferes with the clamping section 91 of the spring piece 9 penetrating into the swinging space 4, so as to ensure that the clamping section 91 is assembled into the swinging space 4 in a correct manner so that the clamping section 91 penetrates into the assembly space 14 so that the spring piece 9 is bent and assembled into the assembly cavity 101, thereby avoiding the spring piece 9 from being installed incorrectly and causing the clamping section 91 to damage the observation port 7, and the extension arm 13 limits the bending degree of the spring piece 9 relative to the inner wall of the swinging space 4 to avoid excessive concave bending of the spring piece 9. After the spring piece 9 is completely assembled into the assembly cavity 101, the spring piece 9 can be released to restore its deformation to drive the clamping section 91 passing through the assembly space 14 to swing around the support portion 22 in the swinging space 4. The clamping section 91 cannot pass through the observation port 7, which can prevent the clamping section 91 that swings in the swinging space 4 from passing through the observation port 7 and detaching outward, until the clamping section 91 and the abutting section 801 form a mutual abutment state, and the assembly operation of the spring piece 9 is completed.
[0044] A sliding hole 104 is provided at a position of the insulating shell 1 near the wiring hole 102, and the inner hole wall of the sliding hole 104 is matched with the outer wall of the driving key 15 in a concave-convex manner so that the driving key 15 can slide up and down along the axial direction of the sliding hole 104. The upper part of the driving key 15 is located at the opening position of the sliding hole 104, and the bottom of the driving key 15 extends into the assembly cavity 101 and abuts against the upper surface of the clamping section 91. The wiring personnel can press the drive key 15 to make the clamping section 91 swing downward in the swinging space 4, and the clamping section 91 and the abutment section 801 are separated from each other to allow the wire to be inserted or removed therefrom. The wiring personnel inserts the connector of the wire into the wiring hole 102 and the threading port 103 in turn, and the part of the connector of the wire passing through the threading port 103 is inserted between the clamping section 91 and the abutment section 801. Preferably, the abutment section 801 is provided with a plurality of slots 804 arranged at intervals, and the end of the clamping section 91 abuts against the corresponding slots 804 to ensure that the clamping section 91 and the abutment section 801 reliably clamp and connect the connector of the wire. Afterwards, the wiring personnel releases the drive key 15, the spring sheet 9 resumes its deformation, and the clamping section 91 swings upward in the swinging space 4 to drive the drive key 15 to reset, and the clamping section 91 and the abutment section 801 clamp the connector of the wire, thereby completing the wiring operation of the terminal. During the wiring operation, the wiring personnel can directly observe the connection status between the inserted clamping section 91 of the wire and the abutment section 801 from the assembly side of the wiring terminal through the observation port 7, so that the wiring personnel can operate the clamping section 91 through the driving key 15 according to the connection status of the wire, to ensure that the clamping section 91 of the spring 9 and the abutment section of the conductive frame 8 reliably clamp the joint of the wire, avoid unreliable connection between the wiring terminal and the wire, facilitate wiring operation, and improve wiring efficiency.
[0045] Embodiment 2:
[0046] refer to Figure 7 , Figure 8 , Fig. 9 , Fig.10, which is different from the first embodiment, the interference structure further includes a wire opening interference portion 61 protruding relative to the wire opening wall 105, the wire opening interference portion 61 protruding downward and extending along the wire opening wall 105, or the wire opening interference portion 61 is arranged in the assembly cavity 101 and below the wire opening wall 105. Preferably, the wire opening interference portion 61 matches with the corresponding vertical side wall 17, and the thickness of the wire opening interference portion 61 is less than or equal to the thickness of the vertical side wall 17. When the spring sheet 9 is bent and assembled in the assembly cavity 101, the wire opening interference portion 61 drives the clamping section 91 to deflect downward so that the clamping section 91 cannot pass through the observation port 7. The baffle interference portion 62 is located on the baffle portion 21 near the wire port interference portion 61, so that the wire port interference portion 61 and the baffle interference portion 62 are arranged opposite to each other, the distance between the baffle interference portion 62 and the wire port interference portion 61 is less than the thickness of the abutment section 801, the minimum distance between the inclined surface 10 and the opposite side of the wire port interference portion 61 is D3, the thickness of the clamping section 91 is D2, and the minimum distance D3 between the baffle interference portion 62 and the opposite side of the wire port interference portion 61 is less than the thickness D2 of the clamping section 91, so that the interference structure interferes with the clamping section 91, preventing the clamping section 91 of the spring sheet 9 from entering the assembly cavity 101 through the observation port 7, so as to ensure that the clamping section 91 is assembled into the swing space 4 in a correct manner, thereby avoiding the spring sheet 9 from being installed incorrectly and causing the clamping section 91 to damage the observation port 7. Preferably, the wire port interference portion 61 and the top end of the baffle portion 21 are staggered to avoid the wire port interference portion 61 affecting the connection status of the wires observed by the wiring personnel through the observation port 7.
[0047] Embodiment three:
[0048] refer to Fig.10 , which is different from the first embodiment, the insulating housing 1 further has an upper baffle 106 extending downward along the wire opening wall 105, and the observation port 7 is formed between the upper baffle 106 and the opposite side of the baffle portion 21. The length of the upper baffle 106 is 40%-80% of the length of the swing space 4, ensuring that when the spring sheet 9 is bent and assembled into the assembly cavity 101, the upper baffle 106 blocks the clamping section 91 from passing through the observation port 7, so that the clamping section 91 cannot be assembled through the observation port 7 but is assembled into the assembly cavity 101 by bending the spring sheet 9. When the clamping section 91 and the abutting section form a mutually separated state, the clamping section 91 is located at the to-be-clamped position, and the observation port 7 corresponds to the to-be-clamped position, so that the wiring personnel can directly observe the connection between the clamping section 91 and the abutting section clamping the wire from the assembly side of the terminal.
[0049] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations.
