Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to a single-strand wedge-shaped wiring terminal. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections, and are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has expanded, and the types have also increased.

[0003] When the existing TB terminal blocks are in use, workers need to insert the corresponding conductive copper busbar each time they connect a set of wires, and then fix the conductive copper busbar with screws. During this process, they need to repeatedly take out and put in the screwdriver, which is very cumbersome.

[0004] Therefore, it is necessary to provide a new single-strand wedge-shaped terminal to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a single-strand wedge-shaped terminal block, which solves the problem that when using the existing TB terminal block, the staff needs to insert the corresponding conductive copper busbar each time they connect a group of wires, and then fix the conductive copper busbar with screws. In this process, the screwdriver needs to be repeatedly taken out and put in, which is very cumbersome.

[0006] The single-strand wedge-shaped terminal provided by the utility model comprises a terminal seat, on which a plurality of first insertion holes and second insertion holes are arranged at intervals, a horizontal seat is fixed between the plurality of first insertion holes, and a vertical seat is fixed between the first insertion hole and the second insertion hole;

[0007] A plurality of the transverse seats are provided with sliding grooves on their surfaces, a notch is provided on the longitudinal seat, a conductive copper bar is provided between the first insertion hole and the second insertion hole, a plurality of thread grooves are provided on the surface of the conductive copper bar, and a tightening screw is threadedly connected to the thread groove;

[0008] A push plate is fixed on one side of the plurality of conductive copper bars.

[0009] In a preferred embodiment, the thickness of the conductive copper bar is smaller than the notch, and two sides of the conductive copper bar are slidably connected to the slide groove.

[0010] In a preferred embodiment, the first insertion hole and the second insertion hole are both configured to be tapered with a bottom diameter smaller than a top diameter.

[0011] In a preferred embodiment, a plurality of push rods are symmetrically arranged on both sides of the terminal seat, one end of the push rod close to the first insertion hole extends into the first insertion hole, and one end of the push rod close to the second insertion hole extends into the second insertion hole.

[0012] In a preferred embodiment, a wedge is provided at one end of the push rod located inside the first insertion hole or the second insertion hole.

[0013] In a preferred embodiment, a transparent protective plate is arranged directly above the terminal seat, and the bottom of the transparent protective plate is square and has four card blocks fixed thereon;

[0014] The terminal seat is provided with four groups of card slots in a square shape, and the card blocks are embedded in the card slots.

[0015] Beneficial effects of the utility model:

[0016] 1. When using this terminal block, the staff can insert one of the two wires to be connected into the first insertion hole, and then insert the other into the second insertion hole (it should be noted that the inserted wire needs to partially extend out of the insertion hole so that it can contact with the conductive copper busbar later). After the insertion is completed, push the push rod to tighten the wire and deform it. The conical insertion hole can prevent the wire from falling out;

[0017] 2. Insert the wires to be connected into the corresponding insertion holes in turn. After all the wires are inserted, use the push plate to slide the conductive copper busbar along the slide groove into the terminal seat. At this time, several thread grooves are located directly above several insertion holes. Finally, use a screwdriver to screw the corresponding tightening screws along the thread groove to the bottom where they contact the wires to complete the installation. The operation is simple and convenient. You don’t need to insert the corresponding conductive copper busbar every time you connect a group of wires, which saves a lot of time.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 The main structure of the single-strand wedge-shaped terminal provided by the utility model is a three-dimensional view Figure 1 ; Figure 2 The main structure of the single-strand wedge-shaped terminal provided by the utility model is a three-dimensional view Figure 2 ; Figure 3 The utility model provides a main structural plan view of a single-strand wedge-shaped terminal.

[0024] In the specific implementation process, Figure 1-Figure 3 As shown, it includes a terminal seat 1, which is characterized in that a plurality of first insertion holes 2 and second insertion holes 3 are spaced apart on the terminal seat 1, a horizontal seat 4 is fixed between the plurality of first insertion holes 2, a vertical seat 5 is fixed between the first insertion holes 2 and the second insertion holes 3, a plurality of horizontal seats 4 are provided with sliding grooves 6 on their surfaces, a notch 7 is provided on the vertical seat 5, a conductive copper bus 8 is provided between the first insertion holes 2 and the second insertion holes 3, a plurality of threaded grooves 9 are provided on the surface of the conductive copper bus 8, a tightening screw 12 is threadedly connected at the threaded groove 9, and a push plate 10 is fixed to one side of the plurality of conductive copper bus 8.

[0025] The thickness of the conductive copper bar 8 is smaller than the notch 7 , and both sides of the conductive copper bar 8 are slidably connected to the slide groove 6 , so that the conductive copper bar 8 can move along the slide groove 6 to above the terminal seat 1 .

[0026] The first insertion hole 2 and the second insertion hole 3 are both configured to be tapered with a bottom diameter smaller than a top diameter, and the bottom diameter of the insertion hole matches the diameter of the wire, ensuring that the wire cannot escape from the insertion hole when deformed.

[0027] A plurality of push rods 11 are symmetrically arranged on both sides of the terminal block 1. One end of the push rod 11 close to the first insertion hole 2 extends into the first insertion hole 2, and one end of the push rod 11 close to the second insertion hole 3 extends into the second insertion hole 3. A wedge is arranged at one end of the push rod 11 located inside the first insertion hole 2 or the second insertion hole 3. When the terminal block is used, the staff can insert one of the two wires to be connected into the first insertion hole 2, and then insert the other into the second insertion hole 3 (it should be noted that the inserted wire needs to partially extend out of the insertion hole so that it can subsequently contact the conductive copper bus 8). After the insertion is completed, the push rod 11 is pushed to tighten and deform the wire, and the conical insertion hole can be used to prevent the wire from falling out.

[0028] A transparent protective plate 13 is arranged directly above the terminal seat 1. The bottom of the transparent protective plate 13 is square and has four card blocks 14 fixed thereon. Four sets of card slots 15 are opened in a square shape on the terminal seat 1. The card blocks 14 are engaged with the card slots 15. The transparent protective plate 13 can be installed above the terminal seat 1 through the card slots 15 and the card blocks 14, which plays a protective role while not affecting the staff's observation of the connection status of the wires.

[0029] Working principle of the utility model: When the terminal block is used, the staff can insert one of the two wires to be connected into the first insertion hole 2, and then insert the other wire into the second insertion hole 3 (it should be noted that the inserted wire needs to partially extend out of the insertion hole so as to contact with the conductive copper bus 8 later). After the insertion is completed, the push rod 11 is pushed to tighten and deform the wire, and the conical insertion hole can prevent the wire from falling out;

[0030] Insert the wires to be connected into the corresponding insertion holes in turn. After all the wires are inserted, hold the push plate 10 to slide the conductive copper bus 8 along the slide groove 6 into the terminal seat 1. At this time, the several threaded grooves 9 are respectively located directly above the several insertion holes. Finally, screw the corresponding tightening screws 12 along the threaded groove 9 to the position where the bottom contacts the wire to complete the installation. The operation is simple and convenient. There is no need to insert the corresponding conductive copper bus 8 every time a group of wires is connected, which saves time.
