[0044] As the structural form of the housing assembly, in this embodiment, the housing assembly has a housing 11 and a cover plate 12 assembled together, and the wiring hole 100 is located on the housing 11 of the housing assembly. The housing 11 and the cover plate 12 can be assembled together by snapping.

[0045] Specifically, see Figure 2 and Figure 3 As shown, the pressing mechanism of this embodiment includes a force-bearing member 4 and a top contact member 5. The force-bearing member 4 is arranged on the housing 11 of the housing assembly, and the force-bearing member 4 is configured to bear external force to form a driving force; the top contact member 5 is arranged in the accommodating cavity 10 of the housing assembly, and the top contact member 5 is transmission-coordinated with the force-bearing member 4 to rotate under the driving force of the force-bearing member 4 and apply a pressing force to the elastic free portion 32 of the elastic clamping member 3. The top contact member 5 here is rotatably arranged in the accommodating cavity 10 of the housing assembly by a pivot.

[0046] According to actual needs, the force-bearing member 4 can also be rotatably arranged on the housing 11 of the housing assembly by means of a pivot. For example, the improved terminal of this embodiment also includes a pivot 1a, the first end of which is fixed on the housing assembly, for example, the pivot 1a here is located on the housing 11 of the housing assembly; the top contact 5 has a first pivot hole group for the second end of the pivot 1a to pass through, and the force-bearing member 4 has a second pivot hole group for the second end of the pivot 1a to pass through; wherein, the first pivot hole group has two first pivot holes 40 symmetrically arranged, and the second pivot hole group has two second pivot holes 50 symmetrically arranged. That is to say, for the first pivot hole group, one first pivot hole 40 is located on the left side of the center axis of the top contact 5, and the other first pivot hole 40 is located on the right side of the center axis of the top contact 5. Similarly, for the second pivot hole group, one second pivot hole 50 is located on the left side of the center axis of the force-bearing member 4, and the other second pivot hole 50 is located on the right side of the center axis of the force-bearing member 4.

[0047] In order to facilitate the installation of the force-bearing member and the top contact member on the housing assembly, in this embodiment, in the axial direction along the pivot axis 1 a , the first pivot hole 40 is located on the inner side or the outer side of the second pivot hole 50 .

[0048] As a way of realizing the force-bearing member, the force-bearing member 4 of this embodiment adopts a button structure and is rotatably disposed on the housing 11 .

[0049] In order to cooperate with the force-bearing member to drive the top contact member to rotate, the end of the force-bearing member 4 is formed with an arc segment 42 that rolls the top contact member as the force-bearing member rotates. The arc segment 42 here is a convex arc segment. Of course, the force-bearing member 4 can also be set to the structural form of a wrench as needed.

[0050] As a structural implementation method of the top contact, see Figure 3As shown, the top contact member 5 of this embodiment includes a top contact member body 51 and a top contact portion 52, the top contact member body 51 is formed with the above-mentioned first pivot hole group, and the top contact member body 51 is configured to bear the driving force of the force-bearing member; the top contact portion 52 is formed on the top contact member body 51, specifically, the top contact portion 52 is formed at the end of the top contact member body 51, and the top contact portion 52 has a contact surface 521 that contacts the elastic free portion 32 of the elastic clamping member 3 and a top contact end 522 that is configured to contact the elastic free portion 32.

[0051] In order to better receive the external force to meet the rotation requirements of the top contact member, in this embodiment, a force-bearing matching structure 41 for matching and bearing the external force is formed on the force-bearing member 4. For example, the force-bearing matching structure 41 here is a hole-shaped structure or a groove-shaped structure.

[0052] The following combination Figures 1 to 6 , the wiring principle of the improved terminal block in this embodiment is explained:

[0053] When wiring or removing wires is required, a screwdriver M is used to apply force to the force-bearing matching structure 41 on the force-bearing member 4, so that the force-bearing member 4 rotates around the pivot 1a (corresponding to Figure 5 The arc segment 42 of the force-bearing member 4 applies pressure to the top contact member body 51 of the top contact member 5 in a rolling manner, and the top contact member 5 also rotates around the pivot 1a (corresponding to Figure 5 The top contact portion 52 of the top contact member 5 moves and presses down the elastic free portion 32 of the elastic clamping member 3. Finally, the top contact end 522 of the top contact portion 52 presses down the elastic free portion 32 of the elastic clamping member 3 to the maximum displacement distance. At this time, a clamping gap is formed between the elastic free portion 32 of the elastic clamping member 3 and the conductor 2 to allow the end of a wire with a large wire diameter to pass through, so that wiring or wire removal operations can be completed through the clamping gap.

[0054] In order to meet the wiring needs of multiple wires, as an improvement, see Figure 7 As shown, the improved terminal block of this embodiment comprises a plurality of housing components which are sequentially connected front and back, and a conductor, an elastic clamping member and a pressing mechanism which correspond to each housing component one by one. In this way, the improved terminal block is composed of a plurality of wiring units, each of which is formed by a housing component, a conductor, an elastic clamping member and a pressing mechanism which correspond to each other one by one, and each wiring unit can meet wiring needs.

[0055] Embodiment 2

In other words, the first pivot 1a on the housing 11 passes through the first pivot hole 40 and the second pivot hole 50 on the left side in sequence, and the second pivot 1b on the cover plate 12 passes through the first pivot hole 40 and the second pivot hole 50 on the right side in sequence. In this way, the rotation setting effect of the top contact member 5 and the force-bearing member 4 on the housing assembly can be achieved by the first pivot 1a and the second pivot 1b respectively cooperating with the corresponding side pivot holes.
