Technical Field
[0001] This utility model relates to the field of terminal block technology, and in particular to a novel terminal block. Background Technology
[0002] Terminal blocks are indispensable accessories in electrical connections. Their core function is to achieve safe and reliable connections between wires through a combination of metal plates and insulating plastic, while also supporting quick disassembly and maintenance.
[0003] In existing terminal blocks, the number of conductive plates is fixed. When connecting a large number of wires, multiple terminal blocks are needed to secure the wires. However, there is no connecting mechanism between the multiple terminal blocks, which leads to them being placed in a disorderly manner, making it inconvenient for staff to carry out maintenance later. Utility Model Content
[0004] This utility model proposes a novel terminal block to overcome the shortcomings of existing technologies.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel terminal block, comprising a base, the base being detachably installed inside a mechanical device and providing support for the whole, wherein a plurality of square nuts are installed inside the base, and a plurality of conductive plates are installed inside the base, wherein the conductive plates can transmit current, and bolts are disposed inside the base, wherein the bolts can fix cables with the help of the square nuts.
[0006] The effect achieved by the above components is as follows: when the terminal block needs to be used, the operator moves the cable so that one end of the cable is above the conductive plate. Then, the operator uses a screwdriver to rotate the bolt. The bolt and the conductive plate together press the cable, thus fixing the cable and completing the cable connection.
[0007] Preferably, a connecting device is provided on one side of the base. The connecting device includes a fixing block, which is fixedly connected to one side of the base. A rectangular groove is formed on the side of the fixing block away from the base. The rectangular block is fixedly connected to the other side of the base. A slot is formed inside the rectangular block, wherein the cross-section of the slot is "T". Two insert plates are slidably inserted on both sides of the fixing block. A pad is fixedly connected to one end of the insert plate. A spring is sleeved on the arc surface of the insert plate, wherein the two ends of the spring are fixedly connected to the fixing block and the pad, respectively. A clamp is fixedly connected to one end of the insert plate, wherein a ramp is formed on one side of the clamp.
[0008] The aforementioned components achieve the following effect: When connecting two bases, the operator moves the two bases closer together. The rectangular block of one base inserts into the rectangular groove of the fixing block of the other base. The rectangular block presses against the ramp of the clamp, causing the clamp and insert plate to move. The spring on the pad deforms. When the clamp is fully inserted into the T-shaped slot, the two clamps move away from each other under the action of the spring's return force, ultimately fixing the rectangular block. When disassembling the two bases, the operator presses the pad, causing the pad to bring the two clamps closer together. The clamps release their fixation on the rectangular block. This connecting device achieves the effect of fixing the two bases together, preventing cable tangling when wiring multiple cables.
[0009] Preferably, the rectangular block is rotatably connected to two rotating parts at the corresponding slot, and the two rotating parts are arranged in a centrally symmetrical manner.
[0010] The effect achieved by the above components is to reduce the friction between the ramp of the clamp and the rectangular block by setting the rotating part and the clamp to rotate.
[0011] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the pad, and the plurality of anti-slip strips are linearly distributed.
[0012] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the mat by setting anti-slip strips, thereby making it easier for the worker to press the mat.
[0013] Preferably, the fixing block has a storage groove at the location corresponding to the pad, wherein the size of the storage groove is larger than the size of the pad.
[0014] The effect achieved by the above-mentioned components is that by setting up a storage slot, the pad can be stored when it is pressed.
[0015] Preferably, the fixing block is fixedly connected to two mutually symmetrical sliders by means of a rectangular groove, and the insert plate is provided with a sliding groove at the corresponding slider, wherein the slider and the sliding groove are slidably adapted.
[0016] The effect achieved by the above components is that by moving the slider in the groove of the insert plate, the direction of movement of the insert plate is restricted, thus preventing the insert plate from shaking.
[0017] Preferably, two symmetrical positioning holes are provided on one side of the fixing block, and two symmetrical positioning rods are fixedly connected to the other side of the base, wherein the size of the positioning rods is adapted to the size of the positioning holes.
[0018] The effect achieved by the above components is that by inserting the positioning rod into the positioning hole of the fixing block, the two bases are limited, thus preventing the two bases from shaking.
[0019] Preferably, one end of the positioning rod is fixedly connected to a pointed protrusion, wherein the tip of the pointed protrusion is far away from the positioning rod.
[0020] The effect achieved by the above-mentioned components is that the pointed protrusions guide the positioning rod, making it easier for workers to insert the positioning rod into the positioning hole of the fixing block, thus providing convenience for the workers.
[0021] In summary, the beneficial effects of this utility model are as follows: When connecting two bases, the operator moves them closer together. A rectangular block from one base inserts into the rectangular slot of the other base's fixing block. The rectangular block presses against the ramp of the clamp, causing the clamp and insert plate to move. The spring on the pad deforms. When the clamp is fully inserted into the T-shaped slot, the spring's return force causes the two clamps to move away from each other, ultimately fixing the rectangular block in place. When disassembling the two bases, the operator presses the pad, bringing the two clamps closer together. The clamps release their hold on the rectangular block. This connecting device effectively secures the two bases, preventing cable tangling when wiring multiple cables. Attached Figure Description

Detailed Implementation
[0024] Reference Figure 1-6As shown, this embodiment discloses a novel terminal block, including a base 1, which is detachably installed inside a mechanical device and provides overall support. Several square nuts 5 are installed inside the base 1; conductive plates 2 are also installed inside the base 1, and these conductive plates 2 can transmit current; bolts 3 are located inside the base 1, and the bolts 3, with the help of the square nuts 5, can secure cables. When the terminal block needs to be used, the operator moves the cable, with one end of the cable positioned above the conductive plates 2. The operator then uses a screwdriver to rotate the bolts 3, causing the bolts 3 and conductive plates 2 to press against the cable, achieving the effect of securing the cable and completing the cable connection. The square nuts 5 increase the torque between themselves and the base 1, facilitating the bolts 3's fixation of the cable.
[0025] Reference Figure 1-6 As shown, a connecting device 4 is provided on one side of the base 1. The connecting device 4 includes a fixing block 41, which is fixedly connected to one side of the base 1. A rectangular groove 42 is provided on the side of the fixing block 41 away from the base 1. A rectangular block 43 is fixedly connected to the other side of the base 1. A slot 45 is provided inside the rectangular block 43. The slot 45 has a "T" shaped cross section. Two insert plates 44 are slidably installed on both sides of the fixing block 41. A pad 47 is fixedly connected to one end of the insert plate 44. A spring 48 is fitted on the arc surface of the insert plate 44. The two ends of the spring 48 are fixedly connected to the fixing block 41 and the pad 47, respectively. A clamp 46 is fixedly connected to one end of the insert plate 44. A ramp is provided on one side of the clamp 46. When it is necessary to connect two bases 1, the operator moves the two bases 1 closer to each other. The rectangular block 43 of one base 1 is inserted into the rectangular groove 42 of the fixing block 41 of the other base 1. The rectangular block 43 presses against the ramp of the clip 46, and the clip 46 and the insert plate 44 move. The spring 48 on the pad 47 deforms. When the clip 46 is fully inserted into the T-shaped slot 45, under the action of the spring 48's return force, the two clips 46 move away from each other. Finally, the clip 46 fixes the rectangular block 43. When it is necessary to disassemble the two bases 1, the operator presses the pad 47. The pad 47 brings the two clips 46 closer to each other, and the clips 46 release their fixation to the rectangular block 43. The connecting device 4 achieves the effect of fixing and connecting the two bases 1, avoiding the situation of cable tangling when wiring multiple cables.
[0026] Reference Figure 1-6As shown, two rotating parts 410 are rotatably connected to the rectangular block 43 at the corresponding slot 45, and the two rotating parts 410 are arranged symmetrically at the center. By setting the rotating parts 410 to rotate with the locking piece 46, the friction between the ramp of the locking piece 46 and the rectangular block 43 is reduced. Several anti-slip strips 49 are fixedly connected to the surface of the pad 47, and the anti-slip strips 49 are linearly distributed. By setting the anti-slip strips 49, the contact area between the worker's hand and the pad 47 is increased, thereby facilitating the worker to press the pad 47.
[0027] Reference Figure 1-6 As shown, the fixing block 41 has a storage groove 416 corresponding to the pad 47, and the size of the storage groove 416 is larger than the size of the pad 47. By setting the storage groove 416, the pad 47 is stored when pressed. The fixing block 41 is fixedly connected to two symmetrical sliders 411 by means of a rectangular groove 42. The insert plate 44 has a sliding groove 412 corresponding to the sliders 411, and the sliders 411 slide and adapt to the sliding groove 412. By the sliders 411 moving in the sliding groove 412 of the insert plate 44, the movement direction of the insert plate 44 is restricted, and the insert plate 44 is prevented from shaking.
[0028] Reference Figure 1-6 As shown, two symmetrical positioning holes 414 are provided on one side of the fixing block 41, and two symmetrical positioning rods 413 are fixedly connected to the other side of the base 1. The size of the positioning rods 413 is adapted to the size of the positioning holes 414. By inserting the positioning rods 413 into the positioning holes 414 of the fixing block 41, the two bases 1 are limited, preventing them from shaking. A pointed protrusion 415 is fixedly connected to one end of the positioning rod 413, with the tip of the protrusion 415 away from the positioning rod 413. The pointed protrusion 415 guides the positioning rod 413, making it easier for workers to insert the positioning rod 413 into the positioning holes 414 of the fixing block 41, thus providing convenience for workers.
[0029] Working principle: When the terminal block needs to be used, the operator moves the cable so that one end of the cable is above the conductive plate 2. Then, the operator uses a screwdriver to rotate the bolt 3. The bolt 3 and the conductive plate 2 together squeeze the cable, achieving the effect of fixing the cable and thus completing the connection of the cable.
[0030] When it is necessary to connect two bases 1, the operator moves the two bases 1 closer to each other. The rectangular block 43 of one base 1 is inserted into the rectangular groove 42 of the fixing block 41 of the other base 1, while the positioning rod 413 is inserted into the positioning hole 414 of the fixing block 41 by means of the pointed protrusion 415, which limits the two bases 1. The rectangular block 43 is pressed against the ramp of the clamp 46 by means of the rotating part 410, and the clamp 46 and the insert plate 44 move. At this time, the slider 411 moves in the slide groove 412 of the insert plate 44, which achieves the effect of limiting the movement of the insert plate 44. The pad 47 When the spring 48 on the upper part deforms, and the clip 46 is fully inserted into the T-shaped slot 45, under the action of the spring 48's return force, the two clips 46 move away from each other. Finally, the clip 46 fixes the rectangular block 43. When it is necessary to disassemble the two bases 1, the worker presses the pad 47 with the anti-slip strip 49. The pad 47 brings the two clips 46 closer to each other, and the clips 46 release their fixation to the rectangular block 43. The connecting device 4 achieves the effect of fixing the two bases 1, avoiding the situation of cable tangling when wiring multiple cables.
