Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a self-locking terminal block. Background Technology

[0002] Self-locking terminal blocks are electrical connection components that achieve automatic locking through a mechanical structure. They are widely used in circuit connections to improve wiring efficiency, reliability, and safety.

[0003] In existing technology, when installing cables, workers need to press a button to press a spring, and then insert the cable into the corresponding terminal hole. When the worker releases the button, the spring returns to its original position and automatically clamps the cable to secure it. However, each cable can only be installed individually, which is inefficient. Utility Model Content

[0004] This utility model proposes a self-locking terminal block to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking terminal block, comprising a housing, wherein the housing is boltably mounted inside a mechanical device, one end of a plurality of spring contacts is fixedly connected to the inside of the housing, a plurality of buttons are slidably connected to one side of the housing, wherein the buttons can compress the spring contacts, and the buttons correspond one-to-one with the spring contacts, a plurality of mounting holes are formed on one side of the housing, wherein the spring contacts are located inside the mounting holes, a plurality of contact pieces are fixedly connected to the inside of the housing, the contact pieces are located at the bottom of the mounting holes, and a conductive element is fixedly connected to one side of the contact pieces.

[0006] The aforementioned components achieve the following effect: Before the cable needs to be used, the operator moves the button, which compresses the spring, causing it to deform. Then, the operator moves the cable, which passes through the mounting hole, with one end of the cable resting against the contact plate. The operator releases the button, and the spring compresses the cable, thus securing it in place. When the terminal block is used, the conductive component is inserted into the mechanical equipment, and the electricity in the cable flows into the mechanical equipment through the contact plate and the conductive component.

[0007] Preferably, the outer shell is provided with a pressing device, which includes two L-shaped plates. The L-shaped plates are detachably installed on both sides of the outer shell with the aid of an auxiliary device. A spring is fixedly connected to one side of the L-shaped plate, and a movable plate is fixedly connected to one end of the spring. A trapezoidal block is fixedly connected to the movable plate at the button position, wherein the inclined surface of the trapezoidal block is inclined downward.

[0008] The aforementioned components achieve the following effects: When installing a single cable, the worker simply presses the corresponding button, causing the corresponding spring to deform, and then the cable is inserted into the corresponding mounting hole. When installing multiple cables, the worker pulls the moving plate, causing the spring on the L-shaped plate to deform. The moving plate moves the trapezoidal block along with the moving plate, and the inclined surface of the trapezoidal block presses against the buttons, causing all the buttons to move downwards. The buttons then press against all the springs, and the worker inserts all the cables into the mounting holes. Finally, the worker releases the moving plate, and under the restoring force of the spring, the moving plate and trapezoidal block move back to their original positions. The trapezoidal block releases its pressure on the buttons, and the springs reset, pressing against the cables to achieve the effect of fixing them in place. The pressing device achieves the effect of pressing against all the buttons, making it convenient for workers to install all the cables simultaneously and improving cable installation efficiency.

[0009] Preferably, a pull plate is fixedly connected to one side of the movable plate, wherein the surface of the pull plate is provided with anti-slip texture.

[0010] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the moving plate by setting up the pull plate, thus bringing convenience to the worker.

[0011] Preferably, the L-shaped plate has two mutually symmetrical limiting rods slidably inserted on its surface, wherein one end of the limiting rod is fixedly connected to the movable plate.

[0012] The effect achieved by the above components is that by setting the limit rod, the moving direction of the moving plate is restricted, thus preventing the moving plate from shaking.

[0013] Preferably, the trapezoidal block has a groove on its inclined surface, and the trapezoidal block is rotatably connected to several rotating parts by means of the groove.

[0014] The effect achieved by the above components is to reduce the friction between the inclined surface of the trapezoidal block and the button by setting a rotating component, so that the trapezoidal block can easily press the button.

[0015] Preferably, the auxiliary device includes two square tubes, which are fixedly connected to the two sides of the outer shell respectively. One side of the L-shaped plate is slidably adapted to the inside of the square tube. Insert rods are slidably inserted at both ends of the square tubes. Insert holes are opened on the L-shaped plate corresponding to the insert rods, wherein the size of the insert rods is adapted to the size of the insert holes.

[0016] The effect achieved by the above components is as follows: when installing the L-shaped plate, the worker moves the L-shaped plate and inserts it into the square tube. Then, the worker moves the insertion rod, which passes through the square tube and inserts into the insertion hole of the L-shaped plate, thus fixing the L-shaped plate. The auxiliary device achieves the effect of fixing the L-shaped plate and also facilitates the worker to replace the L-shaped plate when it is damaged.

[0017] Preferably, one end of the insertion rod is fixedly connected to a pull rope, wherein one end of the pull rope is fixedly connected to the square tube.

[0018] The effect achieved by the above components is that by setting up a pull rope, the maximum displacement of the insertion rod is limited, preventing the insertion rod from falling when not in use.

[0019] Preferably, one end of the insertion rod is fixedly connected to a pointed protrusion, wherein the tip of the pointed protrusion is far away from the insertion rod.

[0020] The effect achieved by the above-mentioned components is that the pointed protrusions make it easier for workers to insert the plug into the socket of the L-shaped plate, thus providing convenience for workers.

[0021] In summary, the beneficial effects of this utility model are as follows: When installing individual cables, the worker simply presses the corresponding button, causing the corresponding spring to deform, and then the cable is inserted into the corresponding mounting hole. When installing multiple cables, the worker pulls the moving plate, causing the spring on the L-shaped plate to deform. The moving plate moves the trapezoidal block along with the moving plate, and the inclined surface of the trapezoidal block presses against the buttons, causing all the buttons to move downwards. The buttons then press against all the springs, and the worker inserts all the cables into the mounting holes. Finally, the worker releases the moving plate, and under the spring's return force, the moving plate and trapezoidal block move back to their original positions. The trapezoidal block releases its pressure on the buttons, and the springs return to their original positions, thus securing the cables. The pressing device achieves the effect of pressing against all the buttons, making it convenient for workers to install all cables simultaneously and improving cable installation efficiency.
