[0002] Current terminal connectors are connecting elements in electronic and electrical components. They are parts that connect conductors to receiving terminals in equipment or cables. They typically consist of a set of metal strips that provide wire connections for input, output, power, and ground. However, existing current terminal connectors have some shortcomings, such as:

[0003] The high-current terminal connector described in application number CN202311390087.3 has a risk of electric shock because most of its structure is open and it lacks an anti-accidental contact structure. During use, operators can easily come into contact with the metal surface of the connector. Utility Model Content

[0004] The purpose of this utility model is to provide a current terminal connector anti-accidental contact structure to solve the problem mentioned in the background art. Most of the existing equipment on the market has an open structure and does not have an anti-accidental contact structure. During use, operators can easily come into contact with the metal surface of the connector, which leads to the risk of electric shock.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a current terminal connector anti-accidental contact structure, comprising a terminal plug, screws, wires, an anti-accidental contact cover plate, and a main body clip;

[0006] The terminal plug is equipped with screws and an anti-accidental contact cover on the left side. A wire is provided above the terminal plug. An integrated buckle is installed between the wires. A plug housing is installed below the integrated buckle.

The anti-accidental contact cover plate has an installation anti-foolproof structure, and the front and back sides are clearly marked to prevent the anti-accidental contact cover plate from being installed backwards. The wire is fitted onto the current terminal by a combination bolt, and then the wire is inserted into the wire-holding groove of the anti-accidental contact cover plate.

[0008] Using the above technical solution, the equipment is connected by bolts and has a simple structure, which not only has good reliability but also has extremely low operating costs.

[0016] Using the above technical solution, the device connects the wires only when the terminal pushes out the short-circuit copper post, thus preventing danger in case of accidental contact.

[0017] As a preferred technical solution of this utility model, the anti-open circuit clip has an inclined copper sheet above it, and a U-shaped claw structure is set below the center line of the anti-open circuit clip. The anti-open circuit clip is fitted on the top of the terminal post. The terminal post has three sections, and the top of each terminal post has a triangular structure.

The terminal plug side plate is installed on the far right side of the terminal plug using a long bolt.

[0020] By adopting the above technical solution, the device can connect multiple terminal plugs in series by setting hexagonal engaging structures at both ends of the terminal plug, which can effectively improve the device's expansion capability and connection power limit.

[0021] As a preferred embodiment of this utility model, a row of anti-slip stripes is evenly arranged below the center line on both sides of the terminal plug, and a square connection hole is provided inside the anti-slip stripe location.

[0022] By adopting the above technical solution, the device can prevent the device from slipping out of your hand during use by uniformly setting a row of anti-slip stripes below the center line on both sides of the terminal plug, thereby further improving the safety of the device.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] Please see Figure 1-8 The present invention provides a structure for preventing accidental contact of a current terminal connector, comprising a terminal plug 1, a screw 2, a wire 3, an anti-accidental contact cover 4, an integrated buckle 5, a plug plastic shell 6, an anti-open circuit clip 7, a compression spring 8, a short-circuit copper post 9, a short-circuit ejection strip 10, a terminal post 11, a square nut 12, and a main body clip 13.

[0046] A screw 2 and an anti-accidental contact cover 4 are installed on the left side of the terminal plug 1. A wire 3 is provided above the terminal plug 1. An integrated buckle 5 is installed between the wires 3. A plug housing 6 is installed below the integrated buckle 5. An anti-open circuit clip 7, a compression spring 8, a short circuit copper post 9, and a short circuit ejection strip 10 are installed inside the plug housing 6. A terminal post 11 is provided below the plug housing 6.

[0047] As a preferred technical solution of this utility model, the terminal plug 1 is locked on the top of the anti-misoperation cover plate 4 by the screw 2. The anti-misoperation cover plate 4 has an installation anti-foolproof structure, and the front and back sides are clearly marked to prevent the anti-misoperation cover plate 4 from being installed backwards. The wire 3 is fitted onto the current terminal by a combination bolt, and then the wire 3 is inserted into the wire-holding groove of the anti-misoperation cover plate 4.

[0048] The main clamp 13, the anti-open circuit clamp 7 and the square nut 12 are installed in the plug housing 6. After the short circuit ejector bar 10 is installed in the plug housing 6, one end of the compression spring 8 is installed on the positioning post of the plug housing 6 and the other end is fixed in the groove of the short circuit copper post 9 to form an anti-open circuit assembly. The anti-open circuit assembly is installed in the plug housing 6 and the buckle on the integrated buckle 5 fixes the anti-open circuit assembly to the plug housing 6.

[0049] After the anti-open circuit clip 7 in the plug housing 6 is installed, it connects to the left and right sides under its own elastic force, which can realize the short circuit of the circuit in the left and right directions; after the anti-open circuit component is installed in the plug housing 6, the short circuit copper post 9 is connected to the anti-open circuit clip 7 under the pushing force of the compression spring 8, which can realize the short circuit of the upper and lower circuits.

[0050] When wire 3 is inserted into terminal plug 1, it opens the anti-open circuit clip 7 connected to the left and right sides of the terminal post 11, and at the same time, it pushes the short-circuit ejector bar 10 upward. After the short-circuit ejector bar 10 pushes the short-circuit copper post 9 upward, the short-circuit copper post 9 separates from the anti-open circuit clip 7, realizing that all short-circuit structures are disconnected after the terminal plug 1 is inserted. When the terminal plug 1 is pulled out, the anti-open circuit clip 7 is short-circuited in pairs on the left and right sides under its own elastic force. When the terminal plug 1 is pulled out, the short-circuit copper post 9 is short-circuited in the vertical direction with the anti-open circuit clip 7 under the pushing force of the compression spring 8, so that the terminal can realize multiple short-circuit connections at the same time, satisfying the diversity of terminal connections.

[0051] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] 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.
