Abstract
The utility model discloses a float structure screw fuse, which comprises a casing with a fuse loading cap; an upper wiring plate and a lower wiring plate are arranged in the casing; a screw tube which is fixed at the lower end of the loading fuse cap is connected with the screw ring which is arranged on the upper wiring plate; a fuse body is arranged in the screw tube, and the lower end of the fuse body is pressed on the lower wiring plate; upper and lower positions of the upper and the lower wiring plates are provided with an upper convex block and a lower convex block on the inner wall of the casing; a spring is arranged below the lower wiring plate. Wiring plates has floating error regulation capacity. The utility model has the advantages of favorable contact performance, favorable buffering and shockproof function, and high safety.
Description
The utility model relates to a kind of fuse.
Fuse is a kind of protection electric appliances; it with melt by the mode of overload current or short circuit current fusing; automatic shutoff circuit; play the effect of protection electrical system; adopting screw thread to compress two of fuse-link, to bring in the conductive structure mode of connecting the turnover line be the principal character of screw type fuse; electric current by fuse-link, is delivered to screwed pipe from following terminal block again, is delivered to upper wiring board by screwed pipe again.But, in existing screw type fuse, terminal block all is that the mode that is screwed is fixed on the base up and down, because the existence of making, equal error being installed, influence the electrical contact performance between fuse-link and terminal block and the screwed pipe greatly, thereby caused the reduction of serviceability.
The purpose of this utility model is: a kind of floating structure screw type fuse is provided, and its terminal block has the ability of unsteady regulating error, therefore has the excellent contact performance, and is safe and reliable.
The technical solution of the utility model is: a kind of floating structure screw type fuse, comprise shell, shell is provided with fuse carrying cap, be provided with upper wiring board and following terminal block in the shell, the lower end of described fuse carrying cap is fixed with screwed pipe, and screwed pipe is connected with the fillet of screw on the upper wiring board, and screwed pipe is built-in with fuse-link, the lower end of fuse-link is pressed in down on the terminal block, and the inwall of described shell is provided with upper protruding block and lower protruding block on the upper-lower position of upper wiring board and following terminal block.
The further technical scheme of the utility model is: a kind of floating structure screw type fuse, comprise shell, shell is provided with fuse carrying cap, be provided with upper wiring board and following terminal block in the shell, the lower end of described fuse carrying cap is fixed with screwed pipe, and screwed pipe is connected with the fillet of screw on the upper wiring board, and screwed pipe is built-in with fuse-link, the lower end of fuse-link is pressed in down on the terminal block, and the inwall of described shell is provided with upper protruding block and lower protruding block on the upper-lower position of upper wiring board and following terminal block; Be provided with spring below the described terminal block down.
The utility model has the advantages that:
1. the screw of no use of terminal block up and down in the utility model directly is fixed on the shell, but limit the up and down of terminal block up and down with the last lower protruding block on the outer casing inner wall, limit the two-dimensional activity of terminal block up and down with outer casing inner wall, terminal block can be located, certain move place is arranged again, be convenient to when fuse carrying cap compresses fuse-link, adjust.
2. the utility model is provided with spring below following terminal block, can fuse-link is upwards afterburning, and press fuse-link tighter, and have buffering and antihunt action.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1. shell; 2. fuse carrying cap; 3. upper wiring board; 4. play terminal block; 5. screwed pipe; 6. the fillet of screw; 7. fuse-link; 8. upper protruding block; 9. lower protruding block; 10. spring.
Embodiment: as shown in Figure 1, a kind of floating structure screw type fuse, comprise shell [1], shell [1] is provided with fuse carrying cap [2], be provided with upper wiring board [3] and following terminal block [4] in the shell [1], the lower end of described fuse carrying cap [2] is fixed with screwed pipe [5], screwed pipe [5] is connected with the fillet of screw [6] on the upper wiring board [3], screwed pipe [5] is built-in with fuse-link [7], the lower end of fuse-link [7] is pressed in down on the terminal block [4], and the inwall of described shell [1] is provided with upper protruding block [8] and lower protruding block [9] on the upper-lower position of upper wiring board [3] and following terminal block [4]; Be provided with spring [10] below the described terminal block [4] down.The screw of no use of terminal block up and down in the utility model directly is fixed on the shell [1], but limit the up and down of terminal block up and down with the last lower protruding block on shell [1] inwall, limit the two-dimensional activity of terminal block up and down with shell [1] inwall, terminal block can be located, certain move place is arranged again, be convenient to fuse-link [7] be adjusted when compressing at fuse carrying cap [2]; The utility model is provided with spring [10] below following terminal block [4], can fuse-link [7] is upwards afterburning, and press fuse-link [7] tighter, and have buffering and antihunt action.
