Novel fuse connection terminal
Technical field
The present invention relates to a kind of can preventing causes the fuse connection terminal inefficacy and changes fuse novel fuse connection terminal very easily because of the fuse scaling loss.
Background technology
Employed fuse connection terminal in electric plug-in strip at present, its fuse installation end all adopts fuse is wrapped on the screw, tighten screw then, allowing screw fastener pad compresses fuse, so it is very inconvenient to change fuse, moreover there is screw thread at the position that fuse is contacted with screw, often easy scaling loss screw thread in blown fuse, cause the terminal disabler, happen occasionally owing to thread damage makes the crag-fast situation of screw in the daily life, bring many inconvenience to people.
Summary of the invention
The invention provides a kind of novel fuse connection terminal.Adopt the press type elastic construction that fuse is installed and more become convenient, can suitably adjust the size of fuse coupling mechanism force by adjusting nut, the fuse coupling mechanism force continues constantly under the operating mode, can guarantee the reliability of its contact; The fuse contact site does not have screw thread, and the fuse installing hole is a through hole, is same axis arranged, is convenient to clear up residual fracture of wire; Can effectively prevent to take place because of thread damage causes the binding post failure phenomenon, minimizing causes accidents such as blown fuse or the overheated initiation fire of contact point because of the fuse loose contact.
In order to address the above problem, the present invention is achieved through the following technical solutions, and it is made up of threaded, adjusting nut, spring, body, installation base plate, hold-down screw, lead fixed screw.Threaded one end is established the rectangle shoulder block, and the through hole of installation insurance silk is established in pin body appropriate location, and for preventing the fuse gouge, the aperture rounding goes sharp; Body is cuboid, and a bottom portion establishes groove, establishes the circular hole that threaded is installed in the middle of the groove, and the fuse installing hole that can become same axis arranged with the fuse installing hole on the threaded is established in the side; The other end of body, the lead installing hole is established on the vertical end plane, and parallel thread pin installing hole is established the screw of fixed body and fixing cord, and they are vertical and through the lead installing hole, with hold-down screw body is fixed on and installs on the base plate, with the lead fixed screw with lead fixed in the lead installing hole.Threaded penetrates from the body recess place, and the rectangle shoulder block embeds in the groove, make the revolution degree of freedom of threaded limited, but the relative body of threaded can move up and down; Threaded is packed into behind the body, is inserted in spring and the adjusting nut of screwing at the end of thread; Adjusting nut plays button simultaneously, and outward appearance is column or mushroom, and hollow is established internal thread, makes with insulating material; Can change the size of fuse coupling mechanism force by adjusting nut.In the time of the installation insurance silk, as long as press by adjusting nut, fuse installing hole on the threaded is alignd with fuse installing hole on the body, fuse is inserted installing hole, releasing is pressed by after the power, threaded is forcing fuse installing hole on the threaded and the fuse installing hole on the body to misplace under the effect of spring force, thereby fuse is blocked.
The invention has the beneficial effects as follows: the fuse coupling mechanism force is adjustable, the fuse coupling mechanism force keeps constant under the work condition state, contact is reliable, can effectively contain and relevant accidents such as causing fire because of the easy scaling loss of fuse loose contact or contact point are overheated solve the problem that lost efficacy because of terminal after the fuse connection terminal screw thread scaling loss; Easy to operate, do not need instrument just can change fuse quickly and easily after operating a switch.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
Among the figure 1, threaded; 2, adjusting nut; 3, spring; 4, body; 5, fuse; 6, base plate is installed; 7, hold-down screw; 8, lead; 9, lead fixed screw.Threaded [1] one end is established the rectangle shoulder block, and the through hole of installation insurance silk [5] is established in pin body appropriate location, and for preventing fuse [5] gouge, the aperture must be gone sharp by rounding; Body [4] is cuboid, and a bottom portion establishes a groove, establishes the circular hole that threaded [1] is installed in the middle of the groove, and the fuse installing hole that can become same axis arranged with the fuse installing hole on the threaded [1] is established in the side; The other end of body [4], the lead installing hole is established on the vertical end plane, the installing hole of parallel thread pin [1] is established the screw of fixed body [4] and the screw of fixing cord [8], they are vertical and through the lead installing hole, with hold-down screw [7] body [4] is fixed on the installation base plate [6], lead [8] is fixed in the lead installing hole with lead fixed screw [9].Threaded [1] penetrates from body [4] groove, and the rectangle shoulder block embeds in the groove, makes the revolution degree of freedom of threaded [1] limited, but the relative body [4] of threaded [1] can move up and down along axis; Threaded [1] is packed into behind the body [4], is inserted in spring [3] and the adjusting nut of screwing on [2] at the end of thread; Adjusting nut [2] plays button simultaneously, and outward appearance is column or mushroom, and hollow is established and threaded [1] internal thread that screw thread mated available insulating material manufacturing; Can change the size of fuse [5] coupling mechanism force by adjusting nut [2].In the time of installation insurance silk [5], as long as press by adjusting nut [2], fuse installing hole on the threaded [1] is alignd with fuse installing hole on the body [4], fuse [5] is inserted installing hole, releasing is pressed by after the power, threaded [1] is forcing fuse installing hole on the threaded [1] and the fuse installing hole on the body [4] to misplace under the effect of spring force, thereby fuse [5] is blocked, to realize reliable and effective connection.
