Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to an anti-loosening terminal block. Background Technology

[0002] In existing technologies, terminal blocks are widely used in the connection of electrical equipment, typically achieving the connection by tightening cables with bolts. These terminal blocks can, to a certain extent, meet basic electrical connection requirements, providing a fundamental guarantee for power transmission and signal transmission between devices.

[0003] However, existing technologies still have drawbacks:

[0004] During equipment operation, bolts may loosen due to factors such as vibration and temperature changes, leading to unstable contact between the cable and the connecting copper plate. This can cause problems such as poor contact and electric arcing, which not only affect the normal operation of the equipment but may also pose safety hazards. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide an anti-loosening terminal block.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an anti-loosening terminal block, comprising a base plate, a vertical plate, a mating copper sheet, and a support plate, wherein the vertical plate is fixedly connected to the upper end of the base plate, the mating copper sheet is disposed on one side of the vertical plate, the mating copper sheet is fixedly connected to the upper end of the base plate, and the support plate is fixedly connected to one side of the vertical plate, and further comprising:

[0007] A pressing plate is disposed on one side of the upright plate;

[0008] An adjusting bolt is rotatably connected to the middle of the upper end of the pressure plate, and the adjusting bolt is threadedly connected to the inside of the support plate;

[0009] The pressure groove is formed at the front and rear of the upper end of the mating copper sheet and at the lower end of the pressure sheet.

[0010] As an improvement, the upright plate and the base plate are integrally formed.

[0011] As an improvement, an insulating sheet is inserted inside the upright plate.

[0012] As an improvement, mounting grooves are provided on the front and rear sides of the upper end of the base plate.

[0013] As an improvement, a fixing bolt is inserted into the mounting slot.

[0014] The advantages of this invention compared to existing technologies are as follows: By setting a wire groove, this invention increases the contact area between the copper contact plate and the cable, thereby improving the contact stability between the cable and the copper contact plate. Even when subjected to external forces such as vibration during equipment operation, the cable is less likely to loosen, avoiding problems such as poor contact and improving the reliability and safety of the terminal block.

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Example 1:

[0023] like Figures 1 to 4As shown, this embodiment proposes an anti-loosening terminal block, including a base plate 1, a vertical plate 2, a connecting copper sheet 3, a support plate 4, a pressure plate 5, an adjusting bolt 6, and a wire pressing groove 7. The vertical plate 2 is fixedly connected to the upper end of the base plate 1. The connecting copper sheet 3 is installed on one side of the vertical plate 2 and fixedly connected to the upper end of the base plate 1. The support plate 4 is fixedly connected to one side of the vertical plate 2. The pressure plate 5 is installed on one side of the vertical plate 2. The adjusting bolt 6 is rotatably connected to the middle of the upper end of the pressure plate 5 and threadedly connected to the inside of the support plate 4. The wire pressing groove 7 is formed at the front and rear of the upper end of the connecting copper sheet 3 and the lower end of the pressure plate 5. After the cable is placed in the wire pressing groove 7 at the upper end of the connecting copper sheet 3, the pressure plate 5 is moved downward by rotating the adjusting bolt 6 to press the cable into the wire pressing groove 7. The wire pressing groove 7 increases the contact area between the connecting copper sheet 3 and the cable, thereby improving stability.

[0024] The upright plate 2 and the base plate 1 are integrally formed.

[0025] An insulating sheet 8 is inserted inside the upright plate 2.

[0026] Mounting grooves 9 are provided on the front and rear sides of the upper end of the base plate 1.

[0027] The mounting slot 9 is fitted with a fixing bolt 91.

[0028] When in use, after placing the cable inside the pressure groove 7 at the upper end of the copper contact plate 3, the pressure plate 5 is moved downward by rotating the adjusting bolt 6 to press the cable inside the pressure groove 7. The pressure groove 7 increases the contact area between the copper contact plate 3 and the cable, thus improving stability.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
