Description

Technical Field

[0001] This utility model relates to the field of switch terminal technology, and in particular to a switch terminal that is easy to assemble. Background Technology

[0002] Switch terminals are components specifically designed for electrical connections. They are mainly used for wiring in equipment such as miniature circuit breakers, residual current circuit breakers, and air switches. They connect directly to the switch via pin-type input terminals, eliminating the need for additional wires or copper / aluminum busbars for transition connections. This replaces the traditional junction box method. The optimized design makes electrical connections more robust and convenient, while also reducing installation space requirements.

[0003] However, since multiple switch terminals are usually required to be used together when wiring, and most of the existing switch terminals on the market are not convenient for workers to combine and fix the switch terminals, the connection between the switch terminals is not tight enough and it is not convenient to expand the combination and use.

[0004] Therefore, those skilled in the art have provided a switch terminal that is easy to assemble in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a switch terminal that is easy to assemble. The connecting block in the connecting mechanism slides with the connecting groove, which restricts the forward and backward movement between the two switch terminals. With the help of the return spring acting on the locking block, the locking block is locked with the left housing, which restricts the up and down movement between the two switch terminals, making it easy to expand and combine the switch terminals.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A switch terminal that is easy to assemble includes a left housing, a right housing, and a fixing mechanism. The fixing mechanism includes two threaded rods, two moving blocks, and a conductive plate. The lower ends of the outer walls of the threaded rods are threadedly connected to the moving blocks. Both the left and right housings are provided with a connecting mechanism, which includes two connecting blocks and three return springs. The front and rear ends of the outer wall on the other side of the left housing are provided with connecting grooves. The front and rear ends of the outer wall on one side of the right housing are fixedly connected to the connecting blocks. The connecting blocks are slidably connected to the connecting grooves. The other side of the return spring is fixedly connected to the left housing. Each return spring has a locking block fixedly connected to one side. The locking blocks penetrate the right housing and engage with the left housing.

[0008] The above technical solution uses a connecting block fixedly connected to the right housing to slide through a connecting groove on the left housing, which restricts the forward and backward movement between the two switch terminals. In conjunction with a reset spring acting on the locking block, the locking block is kept in a locked state with the left housing, restricting the up and down movement between the two switch terminals, which facilitates expanded combination use.

[0009] Furthermore, elastic sheets are fixedly connected to the upper and lower ends of the front and rear outer walls of the left shell, and slots are provided at the upper and lower ends of the front and rear outer walls of the right shell, with the elastic sheets engaging with the slots.

[0010] The above technical solution, by designing the switch terminal housing in half, makes it easier for workers to install the conductive sheet, threaded rod, return spring, moving block and clamping block. The elastic sheet fixedly connected on the left housing is engaged with the slot on the right housing, so that the left housing and the right housing are fixed together, which makes it easier for workers to assemble the switch terminal.

[0011] Furthermore, insertion holes are provided in the middle of the front and rear outer walls of the left and right shells, and the outer walls on both sides of the conductive sheet are slidably connected to the left and right shells, respectively.

[0012] The above technical solution allows the wires to be inserted into the sockets located in the middle of the front and rear outer walls of the left and right housings, enabling the wires to contact the conductive plates and connect the circuit. The conductive plates are slidably connected to the left and right housings, making it easy for workers to install the conductive plates in the designated positions.

[0013] Furthermore, the front and rear ends of the upper ends of the left and right shells are provided with rotating grooves, and the upper ends of the outer walls of the threaded rod are rotatably connected to the rotating grooves.

[0014] The above technical solution allows for the insertion of a threaded rod by creating rotating slots on the left and right housings, while restricting the movement of the threaded rod so that it can only rotate and cannot move up and down. Furthermore, a slot is provided at the upper end of the threaded rod to facilitate the use of a screwdriver to tighten the threaded rod.

[0015] Furthermore, a clamping block is fixedly connected to the lower end of the outer wall on the other side of the movable block, and both the movable block and the clamping block slide inside the left and right shells;

[0016] The above technical solution utilizes a screwdriver to turn the threaded rod, and the threaded connection between the threaded rod and the moving block allows the moving block to move inside the left and right housings with the clamping block. In conjunction with the conductive sheet, the exposed end of the wire can be clamped and fixed to prevent the wire from falling off.

[0017] Furthermore, one side of the outer wall of the card block is spherically convex, and the front and rear ends of the lower outer walls of the left and right shells are fixedly connected with mounting blocks;

[0018] Through the above technical solution, by setting one side of the outer wall of the card block to be spherically protruding, the operator can release the card block from the left housing after applying a certain amount of force to overcome the elastic force of the reset spring on the card block, so that the two switch terminals can be separated. The mounting block fixedly connected to the lower end of the left and right housings can be connected to the mounting rail in the distribution box to fix the switch terminals in the distribution box.

[0019] This utility model has the following beneficial effects:

[0020] 1. The present invention proposes a switch terminal that is easy to assemble. By designing the switch terminal housing in half, it is convenient for workers to install conductive sheets, threaded rods, return springs, moving blocks and clamping blocks. The elastic sheet fixedly connected on the left housing is engaged with the slot on the right housing, so that the left housing and the right housing are fixed together, thereby making it convenient for workers to assemble the switch terminal.

[0021] 2. The present invention proposes a switch terminal that is easy to assemble. The connecting block fixedly connected to the right housing in the connecting mechanism is slidably connected to the connecting groove opened on the left housing, which restricts the back-and-forth movement between the two switch terminals. With the help of the return spring acting on the locking block, the locking block is kept in the locking state with the left housing, which restricts the up-and-down movement between the two switch terminals. This makes it easier for the operator to combine and fix the switch terminals together, and facilitates the expansion and combination of use. Attached Figure Description

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a specific embodiment: a switch terminal that is easy to assemble, including a left housing 1, a right housing 2, and a fixing mechanism 6. Both the left housing 1 and the right housing 2 are provided with a connecting mechanism 7. The connecting mechanism 7 includes two connecting blocks 702 and three return springs 703. The front end and rear end of the outer wall on the other side of the left housing 1 are provided with connecting grooves 701.

Each side of the return springs 703 is fixedly connected with a locking block 704. The locking blocks 704 penetrate the right housing 2 and are locked together with the left housing 1.

[0031] Both the left housing 1 and the right housing 2 have insertion holes 5 in the middle of their front and rear outer walls. The outer walls on both sides of the conductive sheet 605 are slidably connected to the left housing 1 and the right housing 2, respectively. By inserting the wire into the insertion holes 5 in the middle of the front and rear outer walls of the left housing 1 and the right housing 2, the wire can contact the conductive sheet 605 to connect the circuit. The slidable connection between the conductive sheet 605 and the left housing 1 and the right housing 2 makes it easy for the operator to install the conductive sheet 605 in the designated position. One side of the outer wall of the locking block 704 has a spherical convex shape. Mounting blocks 8 are fixedly connected to the front and rear ends of the lower outer walls of housing 1 and right housing 2. By setting one side of the outer wall of the locking block 704 to be spherically protruding, the operator can release the locking block 704 from the left housing 1 after applying a certain amount of force to overcome the elastic force of the return spring 703 on the locking block 704, allowing the two switch terminals to be separated. The mounting blocks 8 fixedly connected to the lower ends of the left housing 1 and right housing 2 can be connected to the mounting rail in the distribution box to fix the switch terminals in the distribution box.

[0032] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The fixing mechanism 6 includes two threaded rods 602, two moving blocks 603, and a conductive plate 605. The lower ends of the outer walls of the threaded rods 602 are threadedly connected to the moving blocks 603.

The upper and lower ends of the outer walls of the front and rear ends of the right housing 2 are provided with slots 4, and the elastic plates 3 are engaged with the slots 4. By splitting the housing of the switch terminal in half, it is convenient for workers to install the conductive plate 605, threaded rods 602, return spring 703, moving block 603, and clamping block 604. The elastic plates 3 fixedly connected to the left housing 1 are engaged with the slots 4 on the right housing 2, so that the left housing 1 and the right housing 2 are fixed together, which facilitates the assembly of the switch terminal. Rotation grooves 6 are provided at the front and rear ends of the upper ends of the left housing 1 and the right housing 2. 01.
