Description

Technical Field

[0001] This application relates to the field of electrical connection technology, and in particular to a terminal block. Background Technology

[0002] Terminal blocks, as key components for electrical connections, are widely used in various electrical equipment. With the miniaturization and high performance of electrical equipment, higher requirements are placed on the reliability, conductivity, and ease of installation of terminal blocks.

[0003] However, in the existing technology, most of the connections are screw-type, which are achieved by tightening the screws to press the wires together. Although the connection is secure, it is time-consuming to install and is prone to poor contact due to loose screws. Utility Model Content

[0004] The purpose of this application is to provide a terminal block that has the advantages of improving the installation efficiency and convenience of the terminal block, reducing installation time, and solving the problems mentioned in the background art.

[0005] The terminal block provided in this application adopts the following technical solution: it includes a terminal housing, an insertion groove is provided on the bottom surface of the terminal housing, a wire body is provided inside the insertion groove, and a limiting groove is provided on the inner side wall of the insertion groove at equal intervals. Two elastic steel plates are provided below the terminal housing, and each elastic steel plate is slidably connected to the inner wall of the corresponding limiting groove. A sliding rod is slidably connected to the inner wall of the terminal housing, a rotating rod is rotatably connected to the outer surface of the sliding rod, two locking blocks are fixedly connected to the outer surface of the rotating rod, and a pressure block is fixedly connected to the bottom end of the sliding rod.

[0006] By adopting the above technical solution, an insertion groove is opened on the bottom surface of the terminal housing to achieve positioning of the insertion groove. The main body of the wire is placed inside the insertion groove. The middle of the main body of the wire is a wire, and the surface is covered with an insulator. After the insulation layer is stripped, a conductor of appropriate length is exposed so that it can be inserted into the insertion groove. A limiting groove is opened on the inner side wall of the insertion groove to achieve positioning of the limiting groove. An elastic steel sheet is placed below the terminal housing and connected to the limiting groove in a sliding connection, so that the limiting groove can limit the elastic steel sheet. A sliding rod is placed on the inner wall of the terminal housing and is set as a sliding connection to achieve limiting of the sliding rod. A rotating rod is installed on the outer surface of the sliding rod. The system is designed with a sliding connection, allowing the operator to raise and lower the sliding rod when pulling the rotating rod. A locking block is installed on the outer surface of the rotating rod, providing a fixed connection and limiting the locking block's movement. When the operator rotates the rotating rod, the locking block rotates, allowing the pressure block to be installed at the bottom of the sliding rod. As the sliding rod rises, the pressure block rises with it, supported by an elastic steel sheet. When the conductor is inserted into the insertion slot, the pressure block, under the action of the elastic steel sheet, presses firmly against the conductor. This combination of the elastic steel sheet and the pressure block improves the efficiency and convenience of terminal block installation, reducing installation time.

[0007] Preferably, the terminal housing has two locking grooves inside, and the inner wall of each locking groove is adapted to the outer surface of the corresponding card block.

[0008] By adopting the above technical solution, the locking groove is opened inside the terminal housing to achieve the positioning of the locking groove. The locking block is adapted to the locking groove. When the pressure block clamps the wire body, the locking block and the locking groove are at the same level. At this time, the operator rotates the rotating rod to make the locking block rotate, so that the locking block can enter the interior of the locking groove. This can prevent the sliding rod and the pressure block from continuously sliding up and down, and prevent the wire body from loosening after being clamped.

[0009] Preferably, a mounting base is provided below the terminal housing, and a conductive sheet is fixedly connected to the upper surface of the mounting base.

[0010] By adopting the above technical solution, the mounting base is placed below the terminal housing, and a conductive sheet is installed on the upper surface of the mounting base. When the wire body is clamped and installed, the wire body can fit with the conductive sheet.

[0011] Preferably, positioning blocks are fixedly connected to both the front and back of the mounting base, and mounting blocks are fixedly connected to the side of each positioning block that is far apart from each other.

[0012] By adopting the above technical solution, positioning blocks are set on the front and back of the mounting base and fixedly connected to achieve the installation of positioning blocks. Mounting blocks are set on the side of the positioning blocks that are far apart from each other, so that when the operator moves the mounting base, the positioning blocks and mounting blocks can move together.

[0013] Preferably, the inner wall of the insertion slot has two positioning slots, and the inner wall of each positioning slot is slidably connected to the outer surface of the corresponding positioning block.

[0014] By adopting the above technical solution, the positioning groove is opened on the inner side wall of the insertion groove to achieve positioning of the positioning groove. The inner wall of the positioning groove is connected to the outer surface of the corresponding positioning block and set as a sliding connection, so that the positioning groove can limit the positioning block, thereby achieving the positioning and installation of the mounting base.

[0015] Preferably, each of the mounting blocks has a fixing bolt on its inner wall, and the outer surface of each fixing bolt is threaded to the inner wall of the terminal housing.

[0016] By adopting the above technical solution, the fixing bolt is set on the inner wall of the mounting block and connected to the inner wall of the terminal housing in a threaded connection. This allows the operator to fix the mounting block and positioning block to the inner wall of the terminal housing by rotating the fixing bolt, thereby enabling the mounting base and conductive sheet to be installed. Conversely, it enables the disassembly and replacement of the conductive sheet.

[0017] Preferably, each of the elastic steel sheets has equidistant sliding grooves on its upper surface, and each sliding groove has a limit pin slidably connected to its inner wall.

[0018] By adopting the above technical solution, the sliding groove is opened on the upper surface of the elastic steel sheet to achieve the positioning of the sliding groove, and the limiting pin is installed on the inner wall of the sliding groove.

[0019] Preferably, the top and bottom ends of each limiting pin are fixedly connected to the inner wall of the corresponding limiting groove.

[0020] By adopting the above technical solution, the top and bottom ends of the limiting pin are connected to the corresponding limiting grooves to form a fixed connection. The limiting pin is fixed to the inner wall of the limiting groove, so that when the elastic steel sheet moves, it can be limited by the connection between the sliding groove and the limiting pin, thereby improving the stability of the elastic steel sheet when moving.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This type of terminal block uses components such as elastic steel sheets, sliding rods, rotating rods, and pressure blocks to strip the conductor from the main body of the wire and insert it into the insertion slot. Pulling the rotating rod then raises the sliding rod and pressure block. The operator releases the rotating rod, and the elastic steel sheet on the inner wall of the limiting slot tightens the pressure block, thus pressing the main body of the wire firmly. This improves the installation efficiency and convenience of the terminal block, reducing installation time. When the conductive sheet needs to be replaced, the operator uses tools to remove the fixing bolts, allowing the mounting base to be pulled out. The conductive sheet can then be removed. For replacement, the new mounting base and conductive sheet are moved, and the mounting base is positioned using a positioning block connected to a positioning slot. The mounting base is then fixed with fixing bolts, thus enabling the replacement of the conductive sheet. Attached Figure Description

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0025] Example 1: A terminal block, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5The device includes a terminal housing 1, with an insertion groove 2 on the bottom surface of the terminal housing 1. A conductor body 3 is located inside the insertion groove 2. The insertion groove 2 is positioned on the bottom surface of the terminal housing 1. The conductor body 3 is placed inside the insertion groove 2, with a conductor in the middle and an insulator on its surface. The insulation layer is removed to expose a conductor of appropriate length that can be inserted into the insertion groove 2. The inner wall of the insertion groove 2 has equidistantly arranged limiting grooves 4. Two elastic steel plates 5 are located below the terminal housing 1. Each elastic steel plate 5 is slidably connected to the inner wall of the corresponding limiting groove 4. The limiting grooves 4 are located on the inner wall of the insertion groove 2 to position the limiting grooves 4. The elastic steel plates 5 are placed below the terminal housing 1 and connected to the limiting grooves 4 in a sliding connection, allowing the limiting grooves 4 to limit the elastic steel plates 5.

[0026] Please see Figure 4 , Figure 6 and Figure 7 A slide rod 6 is slidably connected to the inner wall of the terminal housing 1, and a rotating rod 7 is rotatably connected to the outer surface of the slide rod 6. The slide rod 6 is mounted on the inner wall of the terminal housing 1 in a sliding connection to limit its movement. The rotating rod 7 is mounted on the outer surface of the slide rod 6 in a sliding connection so that when the operator pulls the rotating rod 7, the slide rod 6 can be raised or lowered. Two locking blocks 8 are fixedly connected to the outer surface of the rotating rod 7. A pressure block 10 is fixedly connected to the bottom end of the slide rod 6. The locking blocks 8 are mounted on the outer surface of the rotating rod 7 in a fixed connection to control the locking blocks 8. The limit is that when the operator rotates the rotating rod 7, the locking block 8 can rotate, and the pressure block 10 is installed at the bottom of the sliding rod 6, so that when the sliding rod 6 rises, the pressure block 10 can rise with it. The elastic steel sheet 5 can hold the pressure block 10. When the wire body 3 is inserted into the insertion slot 2, the pressure block 10 can press against the conductor of the wire body 3 under the action of the elastic steel sheet 5. Thus, after the wire body 3 is inserted, the action of the elastic steel sheet 5 and the pressure block 10 can improve the installation efficiency and convenience of the terminal block and reduce the installation time.

[0027] Example 2: A terminal block, please refer to Figure 1 , Figure 6 and Figure 7 The terminal housing 1 has two locking grooves 9 inside. The inner wall of each locking groove 9 is adapted to the outer surface of the corresponding locking block 8. The locking grooves 9 are opened inside the terminal housing 1 to achieve positioning of the locking grooves 9. The locking block 8 is adapted to the locking groove 9. When the pressure block 10 clamps the wire body 3, the locking block 8 and the locking groove 9 are at the same level. At this time, the operator rotates the rotating rod 7 to make the locking block 8 rotate, so that the locking block 8 can enter the interior of the locking groove 9. This can prevent the sliding rod 6 and the pressure block 10 from continuously sliding up and down, and prevent the wire body 3 from loosening after being clamped.

[0028] Please see Figure 1 , Figure 3 and Figure 4 A mounting base 11 is provided below the terminal housing 1. A conductive sheet 12 is fixedly connected to the upper surface of the mounting base 11. The mounting base 11 is positioned below the terminal housing 1, and the conductive sheet 12 is installed on the upper surface of the mounting base 11. When the wire body 3 is clamped and installed, the wire body 3 can fit against the conductive sheet 12. Positioning blocks 14 are fixedly connected to both the front and back of the mounting base 11. Each positioning block 14 has a mounting block 15 fixedly connected to its opposite side. The positioning blocks 14 are fixedly connected to the front and back of the mounting base 11 to achieve the installation of the positioning blocks 14. The mounting blocks 15 are set on the opposite side of the positioning blocks 14 so that when the operator moves the mounting base 11, the positioning blocks 14 and the mounting blocks 15 can move together. Two positioning grooves 13 are opened on the inner wall of the insertion groove 2. The inner wall of each positioning groove 13 is connected to the corresponding positioning groove. The outer surface of block 14 is slidably connected, and the positioning groove 13 is opened on the inner side wall of the insertion groove 2 to realize the positioning groove 13. The inner wall of the positioning groove 13 is connected to the outer surface of the corresponding positioning block 14, which is set as a sliding connection, so that the positioning groove 13 can limit the positioning block 14, thereby realizing the positioning and installation of the mounting base 11. Each mounting block 15 has a fixing bolt 16 on its inner wall. The outer surface of each fixing bolt 16 is threaded to the inner wall of the terminal housing 1. The fixing bolt 16 is set on the inner wall of the mounting block 15 and connected to the inner wall of the terminal housing 1, which is set as a threaded connection. This allows the operator to fix the mounting block 15 and the positioning block 14 to the inner wall of the terminal housing 1 by rotating the fixing bolt 16, thereby enabling the mounting base 11 and the conductive sheet 12 to be installed. Conversely, it enables the disassembly and replacement of the conductive sheet 12.

[0029] Please see Figure 4 and Figure 5 Each elastic steel sheet 5 has equidistantly arranged sliding grooves 17 on its upper surface. Each sliding groove 17 has a limiting pin 18 slidably connected to its inner wall. The sliding grooves 17 are positioned on the upper surface of the elastic steel sheet 5. The limiting pins 18 are installed on the inner wall of the sliding grooves 17. The top and bottom ends of each limiting pin 18 are fixedly connected to the inner wall of the corresponding limiting groove 4. The connection between the top and bottom ends of the limiting pins 18 and the corresponding limiting groove 4 is fixed, thus fixing the limiting pins 18 to the inner wall of the limiting groove 4. When the elastic steel sheet 5 moves, it is limited by the connection between the sliding grooves 17 and the limiting pins 18, thereby improving the stability of the elastic steel sheet 5 during movement.

[0030] The implementation principle of this application embodiment is as follows: First, the operator strips the insulation from the surface of the conductor body 3, exposing a certain length of conductor. Then, the exposed part is inserted into the insertion slot 2. At this time, the operator pulls the rotating rod 7 upward, causing the sliding rod 6 and the locking block 8 to rise. At this time, the elastic steel sheet 5 is compressed. After the conductor is inserted into place, the operator releases the rotating rod 7, causing the sliding rod 6 to descend. Under the action of the elastic steel sheet 5, the pressure block 10 presses the conductor tightly. At this time, the locking block 8 corresponds to the locking groove 9. The operator rotates the rotating rod 7, causing the locking block 8 to rotate. Through the connection between the locking block 8 and the locking groove 9, the sliding rod 6 can be limited, so that the pressure block 10 can be firmly pressed on the surface of the conductor, which can improve the installation efficiency and convenience of the terminal block and reduce the installation time. When the elastic steel sheet 5 is in the limited position... When the inner wall of the slot 4 slides, the sliding groove 17 and the limiting pin 18 are connected to improve the stability of the elastic steel sheet 5 during movement. When the conductive sheet 12 needs to be replaced after long-term use, the operator uses a tool to rotate the fixing bolt 16 to remove it, so that the mounting block 15 can be removed. At this time, the operator can pull the mounting base 11 to remove the positioning block 14 and the conductive sheet 12. Then the operator moves the new mounting base 11 and the conductive sheet 12. Through the connection between the positioning block 14 and the positioning groove 13, the mounting base 11 is positioned and installed. Finally, the connection between the fixing bolt 16 and the mounting block 15 and the terminal housing 1 completes the replacement of the conductive sheet 12, so that the device can easily replace the damaged conductive sheet 12.
