In the utility model, the plug is inserted into the through groove of the insulator and contacts with the extension head, the extension head is mated with the slot of the terminal row, the shrapnel is arranged on the extension head, and the elastic force of the shrapnel makes the distance between the extension head and the slot of the terminal row The fixing between the extension head is more firm to prevent the extension head from falling out of the terminal block slot. The connection block matches the terminal block slot opening, which is more convenient when inserting and pulling out the extension head. This structure can extend the distance between the plug and the terminal block slot. The distance between them is convenient for manual operation of plugging and unplugging.

Description

A special wire clip device for taking power from a terminal block

technical field

The utility model relates to the field of electric power, in particular to a special wire clip device for taking electricity from a terminal row.

Background technique

A terminal block refers to an insulating part that carries multiple or multiple sets of mutually insulated terminal assemblies and is used to fix the support. The function of the terminal block is to connect the lines of the on-screen equipment and the off-screen equipment, and play the role of signal (current and voltage) transmission. At present, some terminal blocks take power through the mating contact between the plug and the socket. The surface of the plug is smooth and easy to fall off, and the socket is often in a long and narrow area.

Utility model content

In order to solve the above problems, the purpose of this utility model is to provide a special wire clip device for taking power from a terminal block. The special wire clip device for taking power from the terminal block solves the problem that common plugs are easy to fall off, and is more convenient when plugging and unplugging.

The utility model realizes above-mentioned purpose by following technical scheme:

A special line clamp device for taking electricity from a terminal block, comprising an insulator, the surface of the insulator is an arc surface, a transparent through groove is provided on the insulator along the length direction, one end of a connecting block is installed on the outer periphery of one end of the insulator, and an extension head is installed on the other end of the connecting block , the insulator is in contact with the extension head, the insulator is fixedly connected to the extension head through the connecting block, the diameter of the through groove is the same as that of the extension head, the center line of the through groove and the center line of the extension head are on a straight line, and the outer wall of the extension head is along the circumferential direction There are several arc-shaped shrapnels with openings facing the extension head, the arc-shaped ends of the shrapnel are fixedly connected with the extension head, and one end of the extension head is an arc surface.

In order to further realize the purpose of the utility model, the following technical solution can also be adopted: the length of the through groove is the same as the length of the extension head. The connecting block is an insulator, and the connecting block is mated with the socket of the terminal row.

The utility model has the advantages that: in the utility model, the plug is inserted into the through groove of the insulator and touches the extension head, the extension head is mated with the slot of the terminal row, the shrapnel is arranged on the extension head, and the elastic force of the shrapnel makes it extend The fixing between the head and the terminal block slot is more firm, preventing the extension head from falling out of the terminal block slot. The distance between the slot and the terminal block is convenient for manual operation of plugging and unplugging. The utility model also has the advantages of simple and compact structure, low manufacturing cost and easy use.

detailed description

A special line clamp device for taking electricity from a terminal block, as shown in Figure 1, including an insulator 2, the surface of the insulator 2 is an arc surface, a transparent through groove 1 is provided on the insulator 2 along the length direction, and a connecting block is installed on the outer periphery of one end of the insulator 2 3, the other end of the connection block 3 is installed with the extension head 4, the insulator 2 is in contact with the extension head 4, the insulator 2 is fixedly connected with the extension head 4 through the connection block 3, the diameter of the through groove 1 is the same as that of the extension head 4, and the through groove The center line of 1 and the center line of the extension head 4 are on a straight line, and the outer wall of the extension head 4 is provided with several arc-shaped shrapnel 5 with openings facing the extension head 4 along the circumferential direction. Fixedly connected, one end of the extension head 4 is an arc surface. The plug is inserted into the slot 1 of the insulator 2 and touches the extension head 4. The extension head 4 is mated with the slot of the terminal block. The elastic piece 5 is arranged on the extension head 4. The elastic force of the elastic piece 5 makes the extension head 4 and the terminal block The slots are fixed more firmly to prevent the extension head 4 from falling out of the terminal block slot. The connection block 3 matches the terminal block slot opening, which is more convenient when inserting and pulling out the extension head. This structure can extend the plug and terminal The distance between the rows of slots is convenient for manual operation of plugging and unplugging.

When the terminal block slot is in a relatively long and narrow area, you can use a plurality of special wire clips for the terminal block, so that the special wire clips for the terminal block are tightly fixed and the contact is firm, the length of the through slot 1 Same as the length of the extension head 4.

In order to make it more convenient for the extension head to be inserted into or pulled out of the terminal block slot, the connection block 3 is an insulator, and the connection block 3 is plugged and matched with the terminal block slot.

The technical solution of the utility model is not limited within the scope of the embodiments described in the utility model. The technical contents not described in detail in the utility model are all known technologies.
