Description

Technical Field

[0001] This utility model relates to the field of terminal assembly technology, and in particular to a double-layer terminal assembly. Background Technology

[0002] A double-layer terminal block is an electrical connector typically used to connect wires and electrical equipment. Its design features two layers: the upper layer connects to the main wire, and the lower layer connects to branch wires. This effectively reduces the number of wires and the size of the connector. This structure makes double-layer terminals more efficient in space utilization while also improving the reliability and stability of the electrical connection.

[0003] Currently, the connection between the wire and the double-layer terminal connector is usually fixed by tightening screws, or by pressing the spring inside the terminal with a tool. After the connector is inserted, the spring resets and clamps it to maintain stability. Both of these methods require tools, which is inconvenient and cannot guarantee that the conductive plate and the connector will make effective contact after long-term use. There is room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-layer terminal assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-layer terminal assembly includes a terminal box. The top of the outer wall of the terminal box has two sets of sockets, each set symmetrically arranged. Below each socket, a mounting groove communicating with it is formed on the outer wall of the terminal box. A card is slidably mounted on the top of the inner wall of the mounting groove, and the card has a corresponding hole for the socket. A conductive sheet is fixed at the bottom between the two symmetrical mounting grooves in each set. The terminal box has a channel for the conductive sheet to pass through. The conductive sheet is erected at one end of the mounting groove. A pressing mechanism that compresses the erected portion of the conductive sheet is installed in the mounting groove. A toggle lever is installed in the mounting groove, and a toggle opening for the toggle lever to pass through is formed at the top of the mounting groove. A through hole for the toggle lever to pass through is formed on the card.

[0007] Preferably, the size of the actuation port is greater than the thickness of the actuation lever to ensure that the actuation lever has room to move.

[0008] Preferably, the pressing mechanism includes two symmetrically arranged mounting workpieces fixed to the inner wall of the mounting groove, and the same extrusion plate is rotatably arranged between the two mounting workpieces. A spring is fixed to the outer wall of the extrusion plate, and the other end of the spring is fixed to the inner wall of the mounting groove.

[0009] Preferably, the actuating rod is rotatably disposed between two installed workpieces, and the middle part of the extrusion plate has a notch for the actuating rod to move, and two extrusion rods that fit against the outer wall of the extrusion plate are fixed to the outer wall of the actuating rod.

[0010] Preferably, the inner wall of the mounting groove is fixed with two symmetrical limiting strips, and the card is provided with a limiting groove that matches the limiting strips to ensure that the card can slide.

[0011] Preferably, two symmetrical top rods are fixed on the inner wall of the mounting groove at the position corresponding to the vertical part of the conductive sheet, and a top rod is fixed on the inner wall of the mounting groove at the position corresponding to the extrusion plate, to prevent excessive tilting of the vertical part of the conductive sheet during the extrusion process, which would make it inconvenient to insert the subsequent power connection terminal.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Because it incorporates a terminal box, mounting slot, socket, toggle port, pressing mechanism, toggle lever, card, and conductive sheet, when the toggle lever is tilted and the locking hole aligns with the socket, the connector can smoothly pass through and contact the conductive sheet in the mounting slot. Releasing the toggle lever causes the pressing plate to not only press the vertical part of the conductive sheet but also to tilt the toggle lever in the opposite direction. Conversely, this causes the locking hole on the card to be removed and misaligned with the socket. Since the connector is already inserted into the socket, the locking hole simply presses the connector, securing it firmly in the socket and mounting slot. This effectively solves the problems mentioned in the background technology, facilitating the insertion and energization of the connector by toggle. Simultaneously, the tilting pressing plate presses the vertical part of the conductive sheet, ensuring effective contact between the conductive sheet and the connector.

[0014] 2. A top rod is fixed on the inner wall of the mounting groove at the position corresponding to the extrusion plate to prevent excessive tilting of the vertical part of the conductive sheet during the extrusion process, which would make it inconvenient to insert the subsequent power connection terminal.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Refer to Figure 1-4 A double-layer terminal assembly includes a terminal box 1. The top of the outer wall of the terminal box 1 is provided with two sets of sockets 3, and the sockets 3 in each set are symmetrically arranged. The outer wall of the terminal box 1 is provided with a mounting groove 2 below each socket 3, which communicates with it. A card 7 is slidably arranged on the top of the inner wall of the mounting groove 2, and the card 7 is provided with a card hole 9 corresponding to the socket 3. The bottom of the two symmetrical mounting grooves 2 in each set is fixed with the same conductive sheet 8, and the terminal box 1 is provided with a channel for the conductive sheet 8 to pass through. The conductive sheet 8 is set upright at one end of the mounting groove 2. A pressing mechanism 5 that squeezes the upright part of the conductive sheet 8 is installed in the mounting groove 2. A toggle lever 6 is installed in the mounting groove 2, and a toggle opening 4 for the toggle lever 6 to pass through is provided on the top of the mounting groove 2. A through hole 10 for the toggle lever 6 to pass through is provided on the card 7.

[0022] In this invention, the size of the actuating opening 4 is greater than the thickness of the actuating lever 6, ensuring that the actuating lever 6 has room to move.

[0023] In this utility model, the pressing mechanism 5 includes two symmetrically arranged installation workpieces 11 fixed to the inner wall of the installation groove 2. The same extrusion plate 12 is rotatably arranged between the two installation workpieces 11. A spring 13 is fixed to the outer wall of the extrusion plate 12, and the other end of the spring 13 is fixed to the inner wall of the installation groove 2.

[0024] In this utility model, the actuating rod 6 is rotatably disposed between two mounting workpieces 11, and the middle part of the extrusion plate 12 is provided with a notch for the actuating rod 6 to move. Two extrusion rods 14 that fit against the outer wall of the extrusion plate 12 are fixed on the outer wall of the actuating rod 6.

[0025] In this utility model, two symmetrical limiting strips 15 are fixed on the inner wall of the mounting groove 2, and the card 7 is provided with a limiting groove 18 that matches the limiting strips 15 to ensure that the card 7 can slide.

[0026] In this invention, two symmetrical push rods 16 are fixed on the inner wall of the mounting groove 2 at the position corresponding to the vertical part of the conductive sheet 8. The push rods 16 are also fixed on the inner wall of the mounting groove 2 at the position corresponding to the extrusion plate 12 to prevent excessive tilting of the vertical part of the conductive sheet 8 during the extrusion process of the extrusion plate 12, which would make it inconvenient to insert the subsequent power connection terminal.

[0027] Working principle: The system comprises a terminal box 1, mounting groove 2, socket 3, toggle port 4, pressing mechanism 5, toggle lever 6, card 7, and conductive sheet 8. In its natural state, the card hole 9 and socket 3 are misaligned and not connected during wiring. The connector cannot pass through the socket 3 to contact the card 7. Therefore, the toggle lever 6 must be moved first, tilting it and pressing the pressing plate 12 under the action of the pressing rod 14. Since the toggle lever 6 passes through the through hole 10 on the card 7, tilting the toggle lever 6 simultaneously pushes the card 7, which is slidably positioned in the mounting groove 2, to slide, aligning the card hole 9 with the socket 3. At this point, the connector can pass smoothly through. When the conductive sheet 8 in the mounting groove 2 comes into contact with the spring 13, the push on the lever 6 is released. Due to the compression of the spring 13, the pressing plate 12 returns to its original position. The pressing plate 12 not only presses the vertical part of the conductive sheet 8, but also presses the lever 6 to tilt in the opposite direction. Conversely, the card hole 9 on the card 7 is removed and misaligned with the socket 3. Since the connector has already been inserted into the socket 3, the card hole 9 simply presses the connector to secure it in the socket 3 and the mounting groove 2, effectively solving the problem mentioned in the background art. This facilitates the insertion and energization of the connector by a toggle. At the same time, the pressing plate 12 tilts and presses the vertical part of the conductive sheet 8 to ensure that the conductive sheet 8 and the connector can make effective contact.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
