[0055] The embodiments of the present application provide a terminal block 100, Figure 1 is a schematic view of the terminal block 100 of the embodiments of the present application, Figure 2 is a sectional view of the terminal block 100 of the embodiments of the present application, as Figure 1 and Figure 2 As shown in the drawings, the terminal block 100 has an upper cover 10, a base 20, a button 30, a spring piece 40 and a conductive element 50.

[0056] The base 20 is provided with at least one wire passage 21 for inserting the wire; the upper cover 10 is detachably connected with the base 20 to form a containing space; the button 30 is slidably arranged in the upper cover 10; the spring piece 40 is arranged in the containing space formed by the upper cover 10 and the base 20, and has an elastically deformable clamping portion 41 and a locking portion 42, wherein the clamping portion 41 is close to the first end A of the spring piece 40, and the locking portion is close to the second end B of the spring piece; the conductive element 50 is electrically connected with the spring piece 40.

[0057] Among them, the button 30 and the clamping portion 41 form a mechanical linkage, and the clamping portion 41 follows the sliding of the button 30 to realize the switching of the locking state of the spring piece 40.

[0058] Through the structure of the above-mentioned terminal block 100 of the embodiments of the present application, the wire is clamped by the A and B ends of the spring piece 40 when inserted into the designated position, which can ensure that the wire is inserted into place and is not easy to fall off, and the disassembly of the wire can be completed by pressing the button 30, thereby improving the safety and convenience of the wire installation and disassembly operation.

[0059] In the above-mentioned embodiments, the embodiments of the present application only take the terminal block 100 with four wire passages 21 as an example, and the number of wire passages 21 can be adjusted according to actual needs, which is not limited by the present application.

[0060] Figure 3 is a schematic view of the upper cover 10 of the embodiments of the present application, as Figure 3As shown, the upper cover 10 is provided with at least one through hole 11, the number of the through hole 11 corresponds to the wire channel 21 provided on the base 20, and the through hole 11 is in communication with the wire channel 21, and the outer diameter of the through hole 11 is greater than the outer diameter of the wire channel 21. Thus, the through hole 11 and the wire channel 21 cooperate to form a channel for inserting the wire. The inner diameter of the through hole 11 and the wire channel 21 should be greater than the diameter of the wire, and the specific setting can be adjusted according to the actual application of the terminal table 100 and the type of wire to be inserted, which is not limited in the present application.

[0061] As shown in Figure 3 , the upper cover 10 also has a first mounting portion 12 and a second mounting portion 13, wherein the first mounting portion 12 is used to mount the upper cover 10 to the base 20, and the second mounting portion 13 is used to mount the button 30 to the upper cover 10 in a slidable manner as shown in Figure 2 .

[0062] In the interior of the upper cover 10, there is also a partition (not shown) that separates each wire channel, so that the wires inserted into each wire channel 21 do not interfere with each other, thereby improving the safety of the terminal table 100.

[0063] Figure 4 is another schematic view of the upper cover 10 of the embodiment of the present application, as shown in Figure 4 , on the other side opposite to the first mounting portion 12 of the upper cover 10, the upper cover 10 also has a third mounting portion 14 and a fourth mounting portion 15, wherein the third mounting portion 14 and the fourth mounting portion 15 are both used to mount the upper cover 10 to the base 20 in a detachable manner. Among them, the first mounting portion 12, the second mounting portion 13, the third mounting portion 14 and the fourth mounting portion 15 are through holes through the upper cover 10, and the fourth mounting portion 15 has an opening in the direction towards the bottom surface of the upper cover 10.

[0064] Figure 5 and Figure 6 are two schematic views of the base 20 of the embodiment of the present application, as shown in Figure 5 , the base 20 has a base 22, at least one first extension 23, and at least one second extension 24, wherein the base 22 extends towards the horizontal direction, the first extension 23 is located on one side of the base 22, and the second extension 24 is located on the other side of the base 22, respectively extending upwards in a direction perpendicular to the base 22, and at least one first extension 23 and at least one second extension 24 are separated from each other.

[0065] Among them, the first protrusion 25 is provided on the outer surface of the base 22 close to the second extension 24, and the second protrusion 26a, 26b is provided on the outer surface of the base 22 close to the first extension 23.

[0066] AsFigure 6 As shown, the second protrusions 26a and 26b can be formed into protrusions of different shapes to cooperate with the third mounting portion 14 and the fourth mounting portion 15 of the upper cover 10. Thus, the first protrusion 25, the second protrusions 26a and 26b respectively cooperate with the shapes of the first mounting portion 12, the third mounting portion 14, and the fourth mounting portion 15 of the upper cover 10. The first protrusion 25 can be fitted into the first mounting portion 12, the second protrusion 26a can be fitted into the third mounting portion 14, and the second protrusion 26b can be fitted into the fourth mounting portion 15, thereby allowing the upper cover 10 and the base 20 to be positioned as follows: Figure 1 The connection shown is detachable.

[0067] like Figure 5 and Figure 6 As shown, the base 20 also has a third extension 27 located between the first extension 23 and the second extension 24, extending upward from the base 22 in a direction perpendicular to the extension direction of the base 22.

[0068] The third extension 27 includes a conductive element holding part 28 and a spring holding part 29. The conductive element holding part 28 extends upward from the base 22 in a direction perpendicular to the extension direction of the base 22, and has a rectangular cross-section. The spring holding part 29 extends from the conductive element holding part 28 in a direction perpendicular to the extension direction of the base 22, and has a triangular cross-section. The conductive element holding part 28 can be used to mount the conductive element 50 to the base 20.

[0069] Figure 7 This is a schematic diagram of the conductive element 50 according to an embodiment of this application, as shown below. Figure 7 As shown, the conductive element 50 has a pin 51, a fixing portion 52, an electrical contact 55, a first parallel portion 53, and a second parallel portion 54, wherein the first parallel portion 53 and the second parallel portion 54 are parallel to the first extension portion 23 and the second extension portion 24. At least one electrical contact 55 is provided on the inner surface of the second parallel portion 54 in the direction toward the first parallel portion 53, and a bent portion 56 is provided at the top in the extending direction of the second parallel portion 54.

[0070] like Figure 7 As shown, the fixing part 52 of the conductive element 50 has a hollow structure. Therefore, the third extension 27 can pass through the hollow structure and be fixed to the fixing part 52 in an interference fit, for example, so that the conductive element holding part 28 is fitted into the hollow structure of the fixing part 52.

[0071] In addition, such as Figure 6 As shown, a groove T is provided on the top of the second extension 24 of the base 20, and a through hole (not shown) is provided on the base of the base 20 to allow the pin 51 to pass through.

[0072] Figure 8This is a schematic diagram of a conductive element 50 mounted on a base 20. With the above structure, the fixing part 52 of the conductive element 50 can be fixed on the conductive element holding part 28 by interference fit, and the outer surface of the conductive element 50 can fit against the inner surface of the base 20. The bent part 56 is fitted into the groove T at the end of the second extension part 24. With this structure, the internal space of the terminal block 100 can be saved while ensuring conductivity.

[0073] Figure 9 This is a schematic diagram of the spring 40 according to an embodiment of this application, as shown below. Figure 9 As shown, the spring 40 has a first end A and a second end B.

[0074] The spring 40 also has a clamping portion 41, a locking portion 42, a bending portion 43, a first connecting portion 44, and a second connecting portion 45. The clamping portion 41 is close to the first end A of the spring 40. The clamping portion 41 is connected to the bending portion 43, and the clamping portion 41 gradually narrows in the direction of extending toward the bending portion 43. That is, the width of the portion of the clamping portion 41 near the first end A is greater than the width of the portion near the bending portion 43. The bending portion 43 is connected to the first connecting portion 44. The first connecting portion 44 is connected to the second connecting portion 45 and the two are perpendicular to each other. The second connecting portion 45 is connected to the locking portion 42, and the locking portion 42 is close to the second end B of the spring 40. The locking portion 42 is formed as a protrusion near the second end B.

[0075] In the above embodiments, such as Figure 9 As shown, the spring 40 also has a conductive part 46, which is a through hole provided on the first connecting part 44 and passing through the first connecting part 44. The conductive part 46 is electrically connected to the conductive element 50.

[0076] Figure 10 This is a schematic diagram showing the connection between the spring 40 and the conductive element 50, as shown below. Figure 10 As shown, the electrical contact 55 of the conductive element is fitted into the conductive part 46 of the spring 40, thereby realizing the conduction between the spring 40 and the conductive element 50, and realizing the electrical connection between the terminal block 100 and the external component through the pin 51.

[0077] In the above embodiments, the top cover 10 is integrally formed, the base 20 is integrally formed, and the spring piece 40 is integrally formed.

[0078] Figure 9 Images (a) and (b) show the unlocked state of the spring 40 and the locked state of the first end A when it engages with the locking part 42, respectively. Figure 9As shown, when downward pressure is applied to the clamping part 41, the first end A of the spring piece 40 can abut against the locking part 42. Continuing to apply pressure to the clamping part 41 will cause the locking part 42 to deform. When the clamping part 41 is pressed to the other side of the locking part 42, the locking part 42 is no longer subjected to pressure from the clamping part 41, its deformation recovers, and the first end A of the spring piece 40 is engaged with the locking part 42, thus keeping the spring piece 40 in place. Figure 9 The locked state is shown in (b).

[0079] Conversely, when downward pressure is applied to the second end B of the spring piece 40, the second end B will cause the locking part 42 to deform in a direction away from the first end A. Continuing to apply pressure to the second end B will disengage the locking part 42 from the first end A, restoring the deformation of the clamping part 41, that is, restoring the spring piece 40 to its original state. Figure 9 The state shown in (a).

[0080] In the above embodiment, the button 30 and the clamping part 41 form a mechanical linkage structure. Therefore, by pressing the button 30, pressure can be applied to the clamping part 41, so that the first end A of the spring piece is engaged with the locking part 42, and the spring piece 40 enters the locked state.

[0081] Figure 11 This is a schematic diagram of the button 30 being mounted on the spring 40 according to an embodiment of this application, as shown. Figure 11 As shown, the button 30 has a main body 31 and a retaining part 32, wherein the retaining part 32 is located on both sides of the main body 31, making the main body 31 a hollow structure with an opening, such as... Figure 11 As shown, the retaining part 32 of the button 30 can clamp the spring piece at the position where the clamping part 41 narrows in the direction of extending toward the bending part 43, so that the spring piece 40 is partially accommodated in the hollow structure of the main body part 31 and forms a mechanical linkage with the button 30.

[0082] like Figure 11 As shown, the spring 40 is in the unlocked state at this time. Through the mechanical linkage structure between the spring 40 and the button 30, pressing the button 30 can make the spring 40 enter the locked state.

[0083] Figure 12 This is another schematic diagram of the button 30 being mounted on the spring 40 according to an embodiment of this application, as shown below. Figure 12 As shown, the spring 40 is in a locked state at this time.

[0084] In the above embodiment, when the wire is inserted into the wire channel 21 of the terminal block 100, the second end B of the wire press spring 40 causes the first end A to disengage from the locking part 42, and the first end A and the second end B clamp the wire.

[0085] Through the above embodiments, since both the clamping part 41 and the locking part 42 of the spring 40 in this application embodiment can be elastically deformed, the force required for the state switching of the spring 40 is more controllable, so that the terminal block 100 provided in this application embodiment can be applied to both rigid wires and flexible wires, thus expanding the application range of the terminal block 100.

[0086] In the above embodiments, such as Figure 2 and Figure 12 As shown, when the first end A engages with the locking part 42, the button 30 is in the lowest position;

[0087] like Figure 2 and Figure 11 As shown, when the first end A is released from the locking part 42, the button 30 is in the highest position.

[0088] In the above embodiments, such as Figure 11 and Figure 12 As shown, button 30 has a first limiting part 33 and a second limiting part 34.

[0089] When button 30 is in its highest position, the first limiting part 33 abuts against the upper cover 10, thereby preventing button 30 from falling out of the upper cover 10. For example, Figure 3 As shown, a third limiting part 16 may also be provided in the second mounting part 13 of the upper cover 10. When the button 30 is in the highest position, the first limiting part 33 abuts against the third limiting part 16, thereby limiting the button 30.

[0090] In addition, when button 30 is in the lowest position, the second limit part 34 can also keep button 30 in the lowest position by interference fit with base 20.

[0091] Figure 13 This is a schematic diagram of the button 30 and spring 40 being mounted on the base 20 according to an embodiment of this application. Figure 13 As shown, when button 30 is in the lowest position, the second limiting part 34 and the spring retaining part 29 of the base 20 are in an interference fit to keep button 30 in the lowest position.

[0092] Through the above embodiments, the highest and lowest positions of button 30 can be maintained and limited, thereby preventing button 30 from falling out and preventing button 30 and spring 40 from being over-pressed, which could damage spring 40.

[0093] Figure 14 This is a schematic diagram of the terminal block 100 after the wire 60 is inserted into it, according to an embodiment of this application. Figure 14 As shown, after the wire is inserted into the terminal block 100, the second end B of the spring 40 is pressed, causing the first end A to disengage from the locking part 42, thereby clamping the wire 60.

[0094] In the above embodiment, when the button 30 is in the highest position, the clamping part 41 closes the wire channel 21; when the button 30 is in the lowest position, the wire channel 21 opens.

[0095] Figure 15 This is another schematic diagram of the terminal block 100 according to an embodiment of this application. In this embodiment, the pre-opening of the wire channel 21 can also be achieved through the mechanical linkage structure between the button 30 and the clamping part 41, such as... Figure 15 As shown, when it is necessary to insert a wire into the terminal block 100, the button 30 can be pressed to the lowest position to lock the spring 40. At this time, the status of the wire channel 21 can be seen by visual inspection, and pre-opening the wire channel 21 can make the wire insertion smoother, thus improving the convenience of the terminal block 100.

[0096] The terminal block 100 provided in this embodiment has a structure that pre-opens the wire channel, allowing various types of wires to be inserted smoothly. The pre-opened button is in a pressed-in state, indicating to the user that wiring is unobstructed and ensuring the wire is properly inserted. When removing the wire, simply pressing the button removes it, ensuring both safety and user convenience. Furthermore, the terminal block provided in this embodiment requires no auxiliary tools for wire installation and removal, making it more convenient and suitable for a wider range of users.
