The wiring terminal on the market usually comprises a terminal body and an insulating shell, wherein the insulating shell can play the function of insulation protection, the insulating shell is usually provided with a wire through hole for the wire to pass into and an opening hole corresponding to the position of the wire pressing screw, and the wire is passed into the insulating shell from the wire through hole and is pressed on the terminal body by the wire pressing screw during wiring. However, in the design of the existing wiring terminal, the opening hole is usually open, which may cause impurities such as water and dust to enter the inside of the insulating shell, thereby affecting the electrical performance and reliability of the wiring terminal. SUMMARY

[0003] In view of this, the utility model aims to provide a wiring terminal capable of improving the protection performance.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] The utility model provides a protective wiring terminal, which comprises a terminal body and a shell arranged outside the terminal body, wherein a closing member is arranged at the opening hole of the shell, the closing member comprises a mounting piece connected with the shell and a cover connected with the mounting piece, and the cover is used for closing and opening the opening hole.

[0006] Preferably, the mounting piece is annular, the mounting piece is matched with the opening hole to form a connection, the cover has a connecting part suitable for nested matching with the mounting piece, and the connecting part is matched with the mounting piece to close the opening hole.

[0007] Preferably, the mounting piece is provided with a buckle, the buckle is inserted into the opening hole and is buckled with the shell, and the edge part of the cover has an outwardly protruding lug.

[0008] Preferably, the buckle extends in the direction of the opening hole along the axial direction of the mounting piece, and a convex rib is arranged on the side surface of the buckle in the upward and downward direction.

[0009] Preferably, the connecting part is an annular body structure, and the annular body structure is suitable for being embedded in the mounting piece.

[0010] Preferably, the edge part of the cover has an outwardly protruding lug, and the inner side of the annular body structure is provided with a rib strip in the circumferential direction.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] Example 1: The terminal block structure of this utility model embodiment is as follows Figures 1 to 5 As shown, it includes a terminal body 1 and a housing 2 disposed outside the terminal body 1. The housing 2 has an opening, which can be a screw hole corresponding to a wire clamping screw or other functional holes. A sealing component is installed at the opening 21. The sealing component includes a mounting part 22 connected to the housing 2 and a cover 23 connected to the mounting part 22. The cover 23 is used to close and open the opening 21. When the opening 21 is not in use, the opening 21 is closed by the cover 23, which can prevent water, dust and other impurities from entering the opening 21 to play a protective role, thereby improving the performance of the terminal. When the opening 21 is needed, the cover 23 is opened, and since the mounting part 22 is connected to the housing 2, the sealing component can be prevented from being lost.

[0027] Further, see Figure 3 and Figure 4 As shown, the mounting component 22 is annular. The mounting component 22 and the opening 21 are connected to form a connection. The mounting component 22 is directly connected to the opening 21 to realize the installation of the closed component without modifying the original structure of the outer shell 1. The cover 23 has a connecting part 231 that is suitable for nesting and cooperating with the mounting component 22. When the connecting part 231 and the mounting component 22 are connected, the cover 23 closes the opening 21. The connection part 231 and the mounting component 22 can limit the cover 23 at the opening 21 to close the opening 21.

[0028] Further, see Figure 3 and Figure 4 As shown, the mounting component 22 is provided with a buckle 221, which extends into the opening 21 and forms a fastening connection with the outer shell 2, thus facilitating the installation of the mounting component 22 on the outer shell 2.

[0029] To facilitate opening the cover 23, an outwardly protruding handle 232 is provided on the side of the cover 23. When opening the cover 23, the handle 232 is pinched and pulled outward for easy operation.

[0030] Continue reading Figure 3 and Figure 4 As shown, the buckle 221 extends axially into the opening 21 along the mounting component 22, and a rib 222 is provided on the side of the buckle 221 in the vertical direction. The rib 222 enhances the strength of the buckle 221 and prevents the buckle 221 from being easily broken or damaged.

[0031] To facilitate the connection between the cap 23 and the mounting component 22 when the cap 23 closes the opening 21, the connecting portion 231 is preferably designed as an annular structure. This annular structure is adapted to be embedded within the mounting component 22, forming a tight interference fit between the annular structure and the annular mounting component 22 to limit the position of the cap 23. See [link to details]. Figure 4 and Figure 5 As shown; preferably, ribs 234 can be provided circumferentially on the inner side of the annular structure, and the ribs 234 can enhance the strength and resilience of the annular structure.

[0032] See Figure 4 As shown, the cap 23 is connected to a collar 25 by a connecting strip 24. The collar 25 is sleeved on the outer periphery of the mounting part 22, so that the cap 34 and the mounting part 22 can be connected together and the assembly is convenient.

[0033] Furthermore, to prevent the collar portion 25 from rotating relative to the mounting member 22, a positioning groove 26 is provided on the mounting member 22, and a positioning block 27 is provided on the collar portion 25. The positioning block 27 cooperates with the positioning groove 26 to restrict the rotation of the collar portion 25 relative to the mounting member 22. As a modified embodiment, the positioning groove 26 can be provided on the collar portion 25, and the positioning block 27 can be provided on the mounting member 22 to achieve the same limiting function.

[0034] See Figure 5 As shown, in order to facilitate the limiting of the collar portion 25, the mounting member 22 has a flange portion 223 extending out of the opening 21. The collar portion 25 is abutted and limited between the flange portion 223 and the outer edge of the opening 21, thereby preventing the collar portion 25 from detaching from the mounting member 22.

[0035] Preferably, the cover 23 is made of a transparent material, so that the user can see the inside of the outer shell 1 through the cover 23.

[0036] Example 2 is basically the same as Example 1, except that the closing component in this example is an integral piece, and the mounting part 22 and the cover 23 are connected as one piece. In this way, it can be integrally molded by injection molding, which can save the process of assembling the mounting part 22 and the cover 23.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
