Abstract
The utility model discloses a safety wire holder comprising a casing, wherein the casing is internally provided with a plurality of wiring cavities, and each wiring cavity is internally provided with a conducting strip. The safety wire holder is characterized in that each wiring cavity is internally provided with a wire pressing block which is rotatably connected with a wire pressing frame fixed in the casing; the surface of the casing corresponding to one side of the wire pressing block near the conducting strip is provided with a wiring port which is communicated with the wiring cavity, and the casing at the other side of the wire pressing block is internally provided with a wiring screw matched with the wire pressing block; and the top part of the wiring screw is lower than the surface of the casing. The wire holder adopts the connection mode of front incoming and front fastening during operation, and conductors are directly wired without any pretreatment, thereby facilitating field operation; an operator can not touch the conducting part during operation as the top of the wiring screw is at least 3mm lower than the surface of the casing, thereby avoiding the occurrence of electric shock; and therefore the safety wire holder has the advantages of simple structure, small and compact volume, convenience in use, high wiring efficiency and good safety.
Description
Technical field:
This practical device relates to arrangements of electric connection, is specifically related to a kind of safe junction block.
Background technology:
When general integral type electric connector is used in the electrical connection of AC converter, can only satisfy the general requirement that AC converter is electrically connected, there is following shortcoming: as the protection deficiency that personnel are got an electric shock; The external cabling inconvenience, wiring efficient is low; Volume is bigger, is not easy to the compact layout of all the other elements etc.
The utility model content:
The purpose of this utility model provides the good safe junction block of a kind of electrical security.
To achieve these goals, the technical solution of the utility model is: a kind of safe junction block, comprise housing, be provided with a plurality of wire connection cavities in the housing, be provided with conducting strip in the wire connection cavity, it is characterized in that being equipped with in each wire connection cavity the line ball piece, this line ball piece is rotationally connected with the pressing line frame that is fixed in the housing, the line ball piece is provided with connection jaws by the surface of shell of conducting strip one side and is communicated with wire connection cavity, be provided with the terminal screw that matches with this line ball piece in the opposite side housing of line ball piece, the top of terminal screw is lower than surface of shell.According to an embodiment of the present utility model, pressing line frame is provided with screwed hole, and screwed hole top is counterbore, and terminal screw is threaded with screwed hole, and the head of terminal screw is absorbed in the counterbore, and the top of terminal screw is lower than surface of shell 3mm at least.This line ball piece is the arc surface of evagination near conductor strip one side, and this arc surface to small part is positioned at the connection jaws below, and this line ball piece forms smooth contact-making surface near the outer perk of terminal screw one side direction below terminal screw.
Junction block of the present utility model adopts the positive fastening connected mode of front inlet wire in operating process, lead need not any preliminary treatment, and directly wiring makes things convenient for execute-in-place.Because the top of terminal screw is lower than surface of shell 3mm at least, so operating personnel touch fully less than current-carrying part in operating process, have avoided the generation of getting an electric shock.Therefore advantage of the present utility model be simple in structure, the volume compact, easy to use, wiring efficient height, and fail safe is good.
Description of drawings:
Fig. 1 is the front view of the utility model one embodiment
Fig. 2 is a cutaway view of the present utility model
Embodiment:
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, junction block of the present utility model comprises housing 1, is arranged with two row's wire connection cavities 2 in the housing 1 in parallel, and every row has 12 wire connection cavities 2.
As shown in Figure 2, be equipped with conducting strip 3 and line ball piece 4 in each wire connection cavity 2, this line ball piece 4 is rotationally connected with the pressing line frame 5 that is fixed in the housing 1, line ball piece 4 is provided with connection jaws by the housing of conducting strip 3 one sides and is communicated with wire connection cavity, be provided with the terminal screw 6 that matches with line ball piece 4 in the opposite side housing 1 of line ball piece 4, the top of terminal screw 6 is lower than housing 1 surface.According to an embodiment of the present utility model, pressing line frame is provided with screwed hole in the housing, and screwed hole top is counterbore, and terminal screw is threaded with screwed hole, and the head of terminal screw is absorbed in the counterbore, and the top of terminal screw is lower than surface of shell 3mm at least.This line ball piece 4 is the arc surface of evagination near conducting strip 3 one sides, and this arc surface to small part is positioned at the connection jaws below, and this line ball piece 4 forms smooth contact-making surface near the outer perk of terminal screw 6 one side direction below terminal screw 6.
During use, electric wire is stretched in the wire connection cavity from connection jaws, electric wire head metal is contacted fully with the arc-shaped surface of line ball piece, the line ball piece under the extruding of electric wire to the terminal screw lopsidedness, simultaneously, tighten terminal screw, terminal screw presses line ball piece contact-making surface downwards, this electrical connector line ball piece is tilted to the electric wire direction, thereby make electric wire head metal closely contact with conducting strip.
As shown in Figure 3, be equipped with lettering home position 7 on the housing in each terminal screw outside, be convenient to carry out the lettering sign to distinguish the wiring position.
