Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, specifically to a pivot rotation handle mechanism. Background Technology

[0002] Common terminal block configurations include an insulating housing, a rotating component, a spring, and a conductive terminal. The rotating component may include an arm, a pivot shaft, and a push block. The rotating component is pivotally connected to the insulating housing via the pivot shaft, with its head end outside the insulating housing. The spring and conductive terminal are installed inside the insulating housing. Rotating the rotating component relative to the insulating housing causes the push block in the rotating component to push the spring to bend, allowing the wire to be inserted through the insertion interface at the housing. After the external force is removed, the spring returns to its original position and engages with the conductive terminal to clamp the inserted wire. This is a conventional terminal block structure in the field. For details, please refer to the patent document with authorization announcement number CN104981943B.

[0003] The drawbacks are that the force applied when turning the lever is relatively large, making it inconvenient to use. In addition, there is a problem that the lever may hit the hand when resetting due to the high speed. These issues need to be improved. Utility Model Content

[0004] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0005] This application discloses a pivot rotating handle mechanism, including an insulating housing and a lever and conductive terminals disposed on the insulating housing. The insulating housing has a plug-in opening for inserting a wire, and the conductive terminals are used for electrical connection with the wire. The lever includes an arm and a pivot portion protruding from the side of the arm. A first protrusion is provided at the horizontal portion of the conductive terminal, and a second protrusion is provided at the bottom wall of the insulating housing cavity corresponding to the first protrusion. The pivot portion is pivotally connected to the hole formed by the ends of the first and second protrusions so that the lever and the insulating housing form a pivotal connection.

[0006] This solution improves the installation structure and position of the pivot joint of the lever component. The conductive terminal and the protrusion on the bottom wall of the insulating housing form a hole for the pivot joint to connect, which helps to improve the assembly speed. In addition, the pivot joint on the side of the arm is basically located at the bottom wall of the insulating housing. This design structure helps to lengthen the lever arm, so that the lever component can be turned with less force, which is more labor-saving.

[0007] Furthermore, the insulating housing includes a main body and an end cap. The end of the main body is provided with an installation port that communicates with the inner cavity of the main body and allows the conductive terminal to enter and exit. The end cap is provided at the installation port. A stop is provided on the inner wall of the inner cavity of the main body. The end cap and the stop cooperate to clamp the conductive terminal located in the middle.

[0008] In this design, the conductive terminal can enter the main body chamber through the mounting port, and then the end cap is fixed at the mounting port. The end cap and the stop block clamp the conductive terminal. This structure has the advantage of easy assembly and molding.

[0009] Furthermore, the conductive terminal also includes a longitudinal portion, which is connected to the horizontal portion at its end. The longitudinal portion abuts against the end cap, and the end of the horizontal portion abuts against a stop block. Increasing the longitudinal portion facilitates expanding the contact area with the end cap, making it easier to abut against the end cap, thereby facilitating clamping and fixing, and also facilitating connection with other wires.

[0010] Furthermore, a locking block is provided on the side of the end cap, which is engaged in a corresponding slot on the wall of the mounting cavity to fix the end cap at the mounting opening, facilitating assembly.

[0011] Furthermore, a slot is provided at the end of the horizontal portion of the conductive terminal, and a protrusion is provided at the tail end of the slot. The protrusion and the second protrusion cooperate with the slot to form a hole for pivotal connection of the pivot portion.

[0012] Furthermore, a groove for the pivot portion is provided at the end of the second protrusion facing the first protrusion, and the groove opening faces the first protrusion. The first protrusion is located at the groove opening to restrict the pivot portion from disengaging from the groove opening. The hole formed by the first protrusion and the groove for pivoting with the pivot portion improves the stability of the pivot connection.

[0013] Furthermore, the end of the boom extends from the groove formed on the insulating shell and moves along the groove. A protrusion 1 is provided on the side of the boom, and a protrusion 2 is provided on the end face of the groove opening near the starting point of the stroke along the movement path of the boom 1. During the boom reset process, the protrusion 1 strikes and passes over the protrusion 2 to return to the starting point. The boom strikes the protrusion 1 during the reset process to slow down the speed and reduce the phenomenon of the boom hitting the hand during reset.

[0014] Furthermore, the arm is located in the space between one side of the second protrusion and the adjacent cavity wall, and a sliding groove is provided in the cavity wall of this space. The sliding groove extends to the mounting port. A plug-in opening for wire insertion is provided at the end cavity wall of the space between the second protrusion and the adjacent cavity wall on the other side. During installation, the arm can be directly inserted into the sliding groove at the mounting port, which is convenient for assembly.

[0016] 1. This utility model improves the pivot structure of the lever component in the terminal block, making it easier to operate and assemble.

[0017] 2. In this utility model, protrusion one and protrusion two work together to slow down the reset speed of the lever and reduce the hand-hitting phenomenon. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figures 1-5As shown, this example illustrates a pivot-rotating handle mechanism, including an insulating housing 1, a lever 3 mounted on the insulating housing 1, and conductive terminals 2. The configuration of the insulating housing can be selected according to requirements; this example uses a common rectangular housing. The conductive terminals 2 are used to form an electrical connection with a wire. For instance, the insulating housing 1 has a insertion opening 103 for inserting a wire, and the conductive terminals 2 are electrically connected to the wire inserted through the insertion opening 103. Regarding the lever 3, as shown... Figure 5 As shown, the lever 3 includes an arm 31, a pivot portion 32 protruding from the side of the arm 31, and a push block 33. Optionally, a protruding plate 35 can be formed on the side of the first end of the arm 31 for easy pressing and pushing with fingers. The pivot portion is similar to a common shaft. The lower part of the arm 31 is located inside the cavity of the insulating housing 1 and is pivotally connected to the insulating housing through the pivot portion 32. The upper part of the arm 31 extends from a groove formed in the insulating housing. The arm moves along the groove. In use, pushing the arm portion outside the insulating housing rotates the arm, and then the push block pushes the spring piece inside the insulating housing cavity to bend. This is a common mating method in terminals and will not be described further.

[0031] The key improvement in this example lies in the pivotal connection structure between the pivot and the insulating shell. For instance, a protrusion 23 is formed at the horizontal part 21 of the conductive terminal 2, such as on the side or top surface. The specific configuration of the protrusion 23 can be selected according to requirements and is not limited here. A protrusion 108 is formed on the bottom wall of the insulating shell cavity corresponding to the protrusion 23. The specific configuration of the protrusion 108 can also be selected according to requirements. In this example, a strip shape is used as an example. When the conductive terminal is installed in the insulating shell cavity, the ends of the protrusion 23 and the protrusion 108 form a hole for pivoting. The pivot part 32 of the lever 3 extends into the hole for pivoting to form a pivot (i.e., pivotal connection). The lever 3 and the insulating shell form a pivotal connection. The arm can be rotated relative to the insulating shell, and then the push block in the lever 3 pushes the spring in the insulating shell cavity to bend, making it easier for the wire to enter through the insertion opening. In this configuration, the pivot part is basically located at the bottom wall of the insulating shell cavity, the lever arm is lengthened, and the levering is easier.

[0032] Optionally, a slot can be formed at the end of the horizontal portion 21 of the conductive terminal, and a protrusion 23 can be formed at the tail end of the slot. The protrusion 1 and the protrusion 2 cooperate with the slot to form a hole for pivoting connection of the pivot portion, which helps to further lengthen the lever arm.

[0033] To improve the stability of the pivot connection, a groove 102 for the pivot connection 32 to be inserted can be formed at the end of the second protrusion 108 facing the first protrusion 23, with the groove opening facing the first protrusion 23. The protrusion 23 and the groove 102 cooperate to form a hole for pivot connection with the pivot connection, such as... Figure 1 As shown, the pivot portion 32 is at least partially in the groove, and the protrusion 23 is at the opening of the groove to prevent the pivot portion from disengaging from the opening.

[0034] In this example, to improve assembly speed, further improvements are made to the insulating housing. For instance, the insulating housing 1 includes a main body 100 and an end cap 101. An installation opening is formed at the end of the rectangular main body 100, communicating with the inner cavity of the main body and allowing conductive terminals to enter and exit. The end cap 101 is fixed to the installation opening to seal it. A stop block 109 is formed on the inner wall of the cavity of the main body 100, such as on the side wall or bottom wall of the cavity. In this example, the stop block 109 is formed on the bottom wall of the cavity of the main body 100. Figure 2 , Figure 3 As shown, when the conductive terminal 2 is inserted into the main body cavity from the mounting port until the end of its horizontal part 21 abuts against the stop block 109, the end cap can be fixed at the mounting port and the end cap abuts against the conductive terminal (such as the other end of the horizontal part). The end cap and the stop block cooperate to clamp the conductive terminal in the middle, which facilitates quick assembly.

[0035] To improve stability and facilitate connection with other wires, the conductive terminal 2 in this example also includes a longitudinal portion 22, which is connected to the horizontal portion 21 at its end, such as... Figure 6 , Figure 1 As shown, the longitudinal portion 22 abuts against the end cap 101 and the end of the horizontal portion 21 abuts against the stop block 109.

[0036] For fixing the end cap at the mounting port, such as by fitting or snapping, in this example, locking blocks 105 are formed on the upper and lower sides of the end cap 101, such as triangular or rectangular shapes, and corresponding slots 104 are formed on the cavity wall of the mounting port. When the end cap is inserted into the mounting port, the locking blocks are engaged in the slots, thereby fixing the end cap at the mounting port, making installation convenient.

[0037] Furthermore, for the insulating housing, multiple chambers can be formed side by side to accommodate multiple rotating parts and conductive terminals, facilitating multi-wire connection. The conductive terminals can be configured as follows: Figure 6 The configuration shown, or multiple independent conductive terminals integrated into a single large conductive terminal, such as... Figure 7 As shown, select according to your needs.

[0038] To address the issue of hand injury during the resetting of the lever component, the following improvements are made in this example: Figure 4 As shown, the end of the boom 31 extends from the groove 106 formed on the insulating housing 1 and the boom 31 moves along the groove. A protrusion 1 34 is formed on the side of the boom 31. A protrusion 2 107 is formed on the end face of the groove near the starting point of the stroke along the movement path of the protrusion 1 34. Since the protrusion 2 107 is on the movement path of the protrusion 1 34, during the rapid reset of the boom 31, the protrusion 1 34 first hits the protrusion 2 to slow down the speed, and then gradually passes over the protrusion 2 to return to the starting point, which helps to reduce the phenomenon of the boom hitting the hand during reset.

[0039] For ease of assembly, in this example, the arm 31 is located in the space between one side of the second protrusion 108 and the adjacent cavity wall, and a groove 106 is formed on the top wall of this space. A plug-in opening 103 for wire insertion is formed at the end of the space between the second protrusion 108 and the adjacent cavity wall on the other side. Figure 3 , Figure 4 As shown, the slide 106 extends to the mounting port. During installation, the boom can be directly inserted into the slide groove at the mounting port, which facilitates assembly.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
