Description

Technical Field

[0001] The utility model relates to a wiring terminal. Background Art

[0002] Terminal blocks are commonly used to electrically connect different wires. They typically consist of a housing and two terminal blocks located at either or both ends of the housing. The terminal blocks include a socket for inserting wires and a clip located within the socket that holds the wires in place. A handle is movably mounted on the outside of the housing to control the clips' tightening and loosening. Inside the housing, conductive members are located to connect the wires in the different terminal blocks.

[0003] Terminal blocks typically include a positioning device that secures the terminal block to a mounting surface or guide rail. This positioning device is typically secured to the lower end of the terminal block via a snap or fastener. The presence of this positioning device adds an additional component to the terminal block, increasing the number of parts. It also requires installation on the terminal block during use, making assembly more cumbersome. A Chinese invention patent application filed by the applicant recently, which discloses a positioning device for a wire connector (i.e., a terminal block) (CN111342293A), discloses such a positioning device for installation with a terminal block. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wiring terminal which has a simple structure, few parts and can be directly used for installation.

[0005] The utility model provides a wiring terminal, at least one end of which includes a wiring portion, which is used to cooperate with a wire for wiring, and the wiring terminal includes a shell, the shell including a first side shell and a second side shell, the inner side of the first side shell is provided with a first connecting mechanism, and the outer side of the second side shell is provided with a second connecting mechanism that can be cooperated with the first connecting mechanism, the first side shell and the second side shell can be spliced ​​together through their first connecting mechanism and the second connecting mechanism, the bottom end surfaces of the first side shell and the second side shell are in a flush position, and positioning plates are correspondingly connected to the two sides of the shell of the wiring terminal, the positioning plates include connecting holes, the positioning plates on both sides of the shell are symmetrically connected to the corresponding positions of the outer sides of the first side shell and the outer sides of the second side shell, and are convex relative to the outer end surfaces of the first side shell and the second side shell, the connecting hole is vertically penetrated and arranged on the positioning plate, and the bottom end surface of the positioning plate is flush with the bottom end surfaces of the first side shell and the second side shell.

[0006] During installation, the screws can be passed through the positioning plates on both sides of the shell along the connecting holes and connected to the mounting plane, so that the wiring terminal can be fixed on the mounting plane as a whole. Since the bottom end surfaces of the positioning plate, the first side shell, and the second side shell are in a flush position, they can be evenly contacted and matched with the mounting plane, thereby achieving stable and reliable installation and fixation of the wiring terminal.

[0007] In the present invention, since the positioning plate and the side shell are integrally connected, they can be directly processed and formed as a whole with the side shell, reducing the number of parts, facilitating production and processing, and making the overall structure of the terminal block simpler and more compact.

[0021] The embodiment of the utility model terminal block is as follows Figure 1-4 As shown: Both ends of the terminal block include a wiring portion, which is used to cooperate with the wire for wiring. The two wires connected to the wiring portions at both ends of the terminal block can be electrically connected together through the terminal block. The terminal block includes a shell, which includes a first side shell 11 and a second side shell 12. A first connecting mechanism is provided on the inner side of the first side shell 11, and a second connecting mechanism that can cooperate with the first connecting mechanism is provided on the outer side of the second side shell 12.

[0022] In this embodiment, the first connecting mechanism and the second connecting mechanism are respectively a plurality of bosses and sockets capable of forming a plug-in positioning fit. In other embodiments, the first connecting mechanism and the second connecting mechanism may also be matching buckles and slots.

[0023] The first side shell 11 and the second side shell 12 can be spliced ​​together through their first connecting mechanism and the second connecting mechanism. The bottom end surfaces of the first side shell 11 and the second side shell 12 are in a flush position. Positioning plates 13 are correspondingly connected to the two sides of the shell of the terminal block. The positioning plates 13 include connecting holes 131. The positioning plates 13 on both sides of the shell are symmetrically connected to the corresponding positions of the outer side of the first side shell 11 and the outer side of the second side shell 12, and are convex relative to the outer end surfaces of the first side shell 11 and the second side shell 12. The connecting hole 131 is vertically penetrated on the positioning plate 13. The bottom end surface of the positioning plate 13 is flush with the bottom end surfaces of the first side shell 11 and the second side shell 12. Figure 4 shown.

[0024] An installation cavity is formed at the connection between the first side shell 11 and the second side shell 12. The installation cavity can be used to install components such as the operating handle, clips and conductive parts of the wiring part. In addition, it can also form a plug hole for inserting the wire into the shell.

[0025] During installation, screws can be passed through the positioning plates 13 on both sides of the shell along the connecting holes 131 and connected to the installation plane, so that the terminal block can be fixed as a whole on the installation plane (such as a wall or a panel of a cabinet). Since the bottom end surfaces of the positioning plate 13, the first side shell 11, and the second side shell 12 are in a flush position, they can be evenly contacted and matched with the installation plane, thereby achieving stable and reliable installation and fixation of the terminal block.

[0026] In the present invention, since the positioning plate 13 and the side shell are integrally connected, they can be directly processed and formed as a whole with the side shell, reducing the number of parts, facilitating production and processing, and making the overall structure of the terminal block simpler and more compact. In addition, the assembly steps of the positioning device (i.e., the positioning plate 13, the connecting hole 131) and the shell are also reduced, thereby improving production efficiency and reducing production and assembly costs.

[0027] The bottom surfaces of the first and second side shells 11, 12 are provided with corresponding slots 14 that can engage with the guide rail brackets. The slots 14 are located at positions corresponding to the positioning plates 13 on both sides of the shell. This allows the shell to be connected to the guide rail brackets, so that the terminal blocks can be fixed to the mounting surface with screws or fixed to the guide rail by engaging with the guide rail brackets.

[0028] The slots 14 on the first side shell 11 and the second side shell 12 are connected to the side of the connecting hole 131 of the adjacent positioning plate 13, which facilitates the injection molding of the first side shell 11 and the second side shell 12 and facilitates demolding during the injection molding process.

[0029] The positioning plate 13 and the slot 14 are both correspondingly arranged at the middle position of the housing along the two end directions thereof, so that the force applied to the terminal block during installation and fixation is more uniform and stable, thereby improving the fixing and installation effect of the terminal block.

[0030] The second embodiment of the present utility model is as follows Figures 5 to 7 As shown, the difference from the above embodiment is that, in addition to the first side shell 11 and the second side shell 12, the housing also includes a third side shell 15 that can be spliced ​​between the first side shell 11 and the second side shell 12. The first connecting mechanism is provided on one side of the third side shell 15, and the second connecting mechanism is provided on the other side of the third side shell 15. The third side shell 15 is spliced ​​between the first side shell 11 and the second side shell 12 via the first and second connecting mechanisms on its sides (cooperating with the first and second connecting mechanisms of the first and second side shells 11, 12). The bottom end surface of the positioning plate 13 is flush with the bottom end surfaces of the first and second side shells 11, 12. The bottom end surface of the third side shell 15 is provided with a slot 14 that can be engaged with the guide rail bracket. The slot of the third side shell 15 is located at a position corresponding to the slots 14 of the first and second side shells, so that the guide rail bracket can also be connected to the bottom end of the third side shell 15.

[0031] The installation cavity is formed between the adjacently spliced ​​first side shell 11 and the third side shell 15 , and between the second side shell 12 and the third side shell 15 .

[0032] In other embodiments, two or more third side shells 15 may also be used. These third side shells 15 can be spliced ​​together through the first connecting mechanism and the second connecting mechanism of the third side shell 15, and all the third side shells 15 can be spliced ​​as a whole between the first side shell 11 and the second side shell 12. Adjacent third side shells 15 can also be spliced ​​to form the above-mentioned installation cavity.

[0033] The third embodiment of the present utility model is as follows Figures 5 to 7 As shown, the difference from the above-mentioned second embodiment is that only one end of the connection terminal includes a connection portion.

[0034] The above embodiment is only one preferred embodiment of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
