A kind of fuse terminalTechnical field
The present invention relates to electricity field, particularly electrical connector, particularly a kind of fuse terminal.
Background technology
In the electrical apparatus, the switching that is switched on or switched off in loop needs to be realized by binding post.Existing a kind of fuse terminal directly fuse terminals is arranged on circuit loop, and the on-off of circuit loop is realized by the switch of power supply, very inconvenient.And the cover plate of original fuse terminals is opaque, directly cannot connect the operating state in it, be unfavorable for directly finding the fault existing for it and hidden danger.
Summary of the invention
The object of the present invention is to provide and a kind ofly realize quick on-off circuitry and be convenient to observe a kind of fuse terminal of inner case.
For solving the problems of the technologies described above, a kind of fuse terminal of the present invention, the insulated handle comprising insulating part and match with described insulating part; Wherein in described insulated handle, be respectively equipped with fusible core and joint pin, two described joint pin intervals arrange and arrange towards described insulating part; Two junction chambers corresponding with described joint pin position are provided with in described insulating part, two pressing line frames are separately positioned in two described junction chambers, two pieces of screws are each passed through two corresponding described joint pins and two described pressing line frames, connect described joint pin and described pressing line frame; In described insulating part, be also provided with two electric conductors, two described electric conductors comprise inserted sheet and are arranged on the metal clips of described inserted sheet one end, and metal clips described in two panels is positioned at the both sides of described inserted sheet one end, for clamping described fusible core; The other end of described inserted sheet through described pressing line frame, be connected on the inwall of described insulating part.
Described joint pin is hollow design, and the bottom of described joint pin and the contact-making surface of described screw are taper design.
State in insulated handle described the indicator light being provided with control circuit and being connected with described control circuit, described control circuit is connected with described fusible core.
Be provided with rotating shaft in described one end stating insulated handle, be provided with rotating seat in one end of described insulating part, described rotating shaft is rotatably provided in described rotating seat, states the connection of insulated handle and described insulating part described in realization.
Transparent cover plate is provided with in the described side stating insulated handle.
The present invention installs fusible core in a kind of fuse terminal insulated handle inside, by connecting a control circuit, indicator light, resistance and fusible core is coupled together, when circuit exceeds normal operating current, fusible core fuses, the highlighted display of indicator light, thus reminds operating personnel overhaul in time and change fusible core; Insulated handle leading flank is designed with transparent cover plate, and whether namely this structure is convenient to observe internal circuit normal, turn increases the degree of protection of product, prevents from getting an electric shock and misoperation; Cartridge screw position is designed with tapering, blocks the polished rod part on screw top with screw fit, thus product in use screw can not exit insulating part; Conductor construction is designed to U-shape, by metallic elastic deformation clamping fusible core; Insulated handle is designed with rotational structure, can connection between quick separating fusible core and electric conductor, realizes quick on-off circuitry; Baffle design becomes damascene structures, decreases the thickness of terminal on the whole.

Embodiment
Below in conjunction with accompanying drawing, a kind of fuse terminal of the present invention is described in further detail.
As shown in Figure 1 to 4, a kind of fuse terminal of the present invention, the insulated handle 1 comprising insulating part 2 and match with insulating part 2.Two joint pin 3 intervals in insulated handle 1 arrange and arrange towards insulating part 2, simultaneously, two junction chambers 4 corresponding with joint pin 3 position are provided with in insulating part 2, two pressing line frames 5 are separately positioned in two junction chambers 4, two pieces of screws 6 are each passed through corresponding two joint pins 3 and two pressing line frames 5, realize the connection of joint pin 3 and pressing line frame 5.Wherein joint pin 3 is hollow design, and the bottom of joint pin 3 and the contact-making surface 9 of screw 6 are taper design, so just can coordinate the polished rod part blocking screw 6 top with screw 6, thus product in use screw 6 can not exit insulating part 2.
The two panels metal clips 8 of inserted sheet 7 one end of two electric conductors is designed to U-shape, by the elastic deformation clamping fusible core (not shown) of metal clips 8, two panels metal clips 8 is positioned at the both sides of inserted sheet 7 one end, for clamping fusible core (not shown), and the other end of inserted sheet 7 through pressing line frame 5, be connected on the inwall of insulating part 2, realize fixing.
In addition, stating in insulated handle 1 indicator light being provided with control circuit and being connected with control circuit, control circuit is connected with fusible core (not shown), indicator light, resistance and fusible core (not shown) are coupled together, when circuit exceeds normal operating current, fusible core (not shown) fuses, the highlighted display of indicator light, thus reminds operating personnel overhaul in time and change fusible core (not shown)
Rotating shaft 10 is provided with in the one end stating insulated handle 1, rotating seat 11 is provided with in one end of insulating part 2, rotating shaft 10 is rotatably provided in rotating seat 11, realize the connection stating insulated handle 1 and insulating part 2, can connection between quick separating fusible core (not shown) and electric conductor, realize quick on-off circuitry.
Whether normal for the ease of observing internal circuit, be provided with transparent cover plate 12 in the side stating insulated handle 1, and dividing plate 13 is designed to damascene structures, decreases the thickness of terminal on the whole.
The present invention installs fusible core in a kind of fuse terminal insulated handle inside, by connecting a control circuit, indicator light, resistance and fusible core is coupled together, when circuit exceeds normal operating current, fusible core fuses, the highlighted display of indicator light, thus reminds operating personnel overhaul in time and change fusible core; Insulated handle leading flank is designed with transparent cover plate, and whether namely this structure is convenient to observe internal circuit normal, turn increases the degree of protection of product, prevents from getting an electric shock and misoperation; Cartridge screw position is designed with tapering, blocks the polished rod part on screw top with screw fit, thus product in use screw can not exit insulating part; Conductor construction is designed to U-shape, by metallic elastic deformation clamping fusible core; Insulated handle is designed with rotational structure, can connection between quick separating fusible core and electric conductor, realizes quick on-off circuitry; Baffle design becomes damascene structures, decreases the thickness of terminal on the whole.
Below the preferred embodiment of the invention is illustrated, but the present invention is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the scope of the application.
