[0054] The detailed description and technical contents of the present invention are described as follows with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0055] The present invention provides a terminal block with a pressurizing function, such as Figure 6 As shown, it is used to plug a wire 900 and make the terminal block (terminal block for short) 100 with a pressurizing function of the present invention and the wire 900 conduct to each other.

[0056] like Figures 1 to 5 As shown, the terminal block 100 of the present invention comprises: a housing structure 1 , a handle 2 , a spring 3 and an elastic component 5 .

[0057] The housing structure 1 includes a housing (which may be a two-piece structure including a first housing 11 and a second housing 12) and a terminal 4, wherein the terminal 4 is fixed in the housing and partially exposed from the housing. Of course, the housing in the housing structure 1 may also be a single-piece structure (not shown in the figure), and the present invention is not limited to this. In the case of a two-piece housing, the first housing 11 and the second housing 12 are combined with each other and together form a rotating shaft 13 (such as Figure 4 As shown) and a socket 14.

[0058] The terminal 4 has a boss 41, a foot 42 and a connecting plate 43, and the connecting plate 43 is connected between the boss 41 and the foot 42. After the terminal 4 is fixed in the housing, only a part of the foot 42 is exposed outside the housing, so as to facilitate welding of the exposed part to a circuit board (not shown in the figure). Specifically, the boss 41 is provided with a fixing portion 411, and the fixing portion 411 can be a snap groove as shown in the figure, but the present invention is not limited to this, as long as it can produce a fixing effect on a part of the elastic component 5; the connecting plate 43 has a setting portion 431, and the setting portion 431 can be a convex column as shown in the figure, but the present invention is not limited to this, as long as it can be used to set the elastic component 5.

[0059] The handle 2 is movably disposed in the housing and partially exposed from the housing, so that it can move like a seesaw with one point of the housing as a support point. Specifically, the handle 2 has a pressing portion 21, a driving portion 22, and a necking portion 23. The necking portion 23 is connected between the pressing portion 21 and the driving portion 22, and the thickness of the necking portion 23 is smaller than the thickness of the pressing portion 21 and the driving portion 22. When the user presses the pressing portion 21, the handle 2 will perform a seesaw action as described above, so that after pressing the pressing portion 21 downward, the driving portion 22 can move upward.

[0060] The spring piece 3 is disposed in the housing, and has a first fixed section 31, a crimping section 32 and a connecting portion 33, wherein the connecting portion 33 is connected between the first fixed section 31 and the crimping section 32. The connecting portion 33 is curved (e.g., U-shaped) and is wound around the rotating shaft 13, and the first fixed section 31 is fixed to the housing structure 1.

[0061] Specifically, the first fixing section 31 can be fixed to the housing in the housing structure 1, or can be fixed to the terminal 4 in the housing structure 1. In this embodiment, the boss 41 fixed to the terminal 4 is taken as an example for explanation. After the first fixing section 31 is fixed, the crimping section 32 can elastically swing relative to the first fixing section 31 along a swing path R.

[0062] Specifically, a portion of the crimping section 32 corresponds to (including being spaced, adjacent to, and adjacent to) the driving portion 22 , and another portion of the crimping section 32 corresponds to and blocks the aforementioned insertion hole 14 .

[0063] In addition, the connecting portion 33 may further define an escape opening 331 , and the necked portion 23 of the handle 2 is located in the escape opening 331 , so that the driving portion 22 can be smoothly adjacent to the crimping section 32 .

[0064] The elastic component 5 is disposed in the housing and has a second fixed section 52 and a pressurizing section 53. The second fixed section 52 is fixed to the housing structure 1, and the pressurizing section 53 is located on the swing path R and can swing elastically relative to the second fixed section 52.

[0065] Specifically, the second fixing section 52 can be fixed to the housing in the housing structure 1, or fixed to the terminal 4 in the housing structure 1. In this embodiment, the boss 41 fixed to the terminal 4 is taken as an example for explanation. Specifically, the second fixing section 52 is fixed to the aforementioned fixing portion 411. In this way, the pressurizing section 53 can move elastically (including elastic expansion and contraction and elastic swing) relative to the second fixing section 52.

[0066] The elastic component 5 can be a straight-tube spring (not shown in the figure), so it can be fixed only by the second fixed section 52, and the pressurizing section 53 can be elastically extended relative to the second fixed section 52; the elastic component 5 can also be a torsion spring as shown in the figure, so the elastic component 5 also has a sleeve portion 51, the sleeve portion 51 is connected between the second fixed section 52 and the pressurizing section 53, and the sleeve portion 51 is sleeved on the aforementioned setting portion 431, so that the elastic component 5 can use the sleeve portion 51 as an axis to allow the pressurizing section 53 to elastically swing relative to the second fixed section 52. In detail, the pressurizing section 53 can also be turned and extended to have an extension section 54, and the pressurizing section 53 is connected to the sleeve portion 51 by the extension section 54, so that the pressurizing section 53 can be smoothly located on the aforementioned swing path R by utilizing such turns.

[0067] By this, Figure 5, Figure 6 and Figure 7 As shown, when the user wants to plug the wire 900 into the terminal block 100, the user first presses the pressing portion 21 of the handle 2, so that the driving portion 22 of the handle 2 drives the crimping section 32 of the spring 3 to swing upward along the aforementioned swing path R. After the upward swing, the crimping section 32 no longer blocks the insertion hole 14, and also drives the pressurizing section 53 of the elastic component 5 to swing upward, so that both the crimping section 32 and the pressurizing section 53 generate elastic restoring force; then the wire 900 is inserted from the insertion hole 14 into the aforementioned shell The wire 900 is inserted into the body, and the force of pressing the handle 2 is released, so that the crimping section 32 of the spring 3 can be crimped onto the wire 900 by its elastic restoring force. At the same time, the pressurizing section 53 of the elastic component 5 can also pressurize the crimping section 32 by its elastic restoring force, thereby increasing the elastic crimping force of the crimping section 32 on the wire 900, thereby forcing the wire 900 to be firmly clamped between the crimping section 32 and the foot 42, and the wire 900 and the foot 42 are also in contact with each other and are conductive.

[0068] Therefore, even if the elastic crimping force of the crimping section 32 of the spring sheet 3 is insufficient to clamp the wire 900, the elastic component 5 can pressurize the crimping section 32 of the spring sheet 3, so as to ensure that the crimping section 32 is firmly crimped to the wire 900, thereby avoiding poor contact or even loosening of the wire 900 to the terminal 4.

[0069] In addition, if Figures 1 to 5 As shown, in order to guide the swing of the pressurizing section 53 of the elastic component 5, a guide groove 121 can be added to the inner surface of the second housing 12, and one end of the pressurizing section 53 extends into the guide groove 121, so that the pressurizing section 53 can be guided by the guide groove 121 when swinging. In order to stop the pressurizing section 53 of the elastic component 5, the connecting plate 43 of the terminal 4 also has a stopper 432, which is adjacent to the pressurizing section 53, so that the pressurizing section 53 is stopped by the stopper 432.

[0070] In summary, the terminal block with a pressurizing function of the present invention can achieve the intended purpose of use and solve the deficiencies of the prior art.

[0071] The above description is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
