Description

Wiring terminal plate

The utility model discloses a kind of new arrangement plate row, especially a kind of connecting terminal block.It belongs to electrical engineering device technology field.

The electrical wiring plate is widely used in all trades and professions as the electrical engineering device.The conventional mode of connection is that the screw shimmings that adopt connect admittedly more, or adopts welding manner.These modes of connection, wiring operative employee duration, the action trouble is not suitable for producing in enormous quantities electric product, and general terminal block does not have temperature control equipment.When wiring loose contact or lead are excessive by electric current, often, cause unnecessary loss owing to the too high fire that causes of terminal block place temperature.

The purpose of this utility model is exactly the deficiency that will solve the conventional mode of connection, designs a kind of connecting terminal block.This line bank will have two wires, three-way, four lines or more connector lugs, and it is simple that its structure is wanted, and the wiring convenient and reliable operation is firm.This connecting terminal block will have temperature control equipment, prevents that temperature is too high and causes fire.

Task of the present utility model is that following technical scheme realizes: developed a kind of connecting terminal block.This line bank has an insulating body.This insulating body is a single injection-molded, and it contains the cuboid hole groove of several band wing grooves.In the groove of all holes, be embedded with flat cuboid metal connection terminal board.Wiring hole has wiring hole at the bottom of the box at the bottom of the flat cuboid box of this terminal board.The perforation that aligns of the plug wire hole of this hole and hole groove.Wire head to be connect through hole thus is inserted in the metal connection terminal board.The opening terminal block that the horizontal opposite side sidewall of the flat-square shaped of this terminal board extends is stretched the place, hole at cuboid hole groove, and by the separate slot plate all opening terminal blocks is kept apart.This opening terminal block that stretches out is board plug type, can socket in the row and insert in the main circuit.Being provided with the vertical cave of temperature sensor on the insulating body between every adjacent metal binding post box, be provided with Shang Tiaogai above the vertical cave at this.The setting of being somebody's turn to do the cave of hanging down is for when temperature is too high, prevents that the circuit fire is provided with.Can load temperature fuse in the cave of hanging down, the joint with fuse inserts total control circuit again.When connecting terminal block because of abnormal temperature when too high, this temperature fuse fuses automatically, total control circuit cuts off, and plays a protective role.In the cave of hanging down, also can load temperature controller,, and then control other circuit workings with the supervisory circuit variations in temperature.

Two " L " shape the end of a thread locking reeds that can lock wire head are housed in the box body of the flat cuboid metal connection terminal board that this connecting terminal block is designed.The centerline hole of wiring hole at the bottom of the flat cuboid box is just in time aimed on the top of the oblique bullet face of the weak point of this reed.Contact has the pressure tongue bottom surface of locking pad on the part skewback of the oblique bullet face of the weak point of this ramp type.When using this connecting terminal block, can directly solid conductor be inserted in plug wire hole and the wiring hole, like this, wire head just can be oppressed short oblique bullet face and be sunk, the center, hole of wiring hole at the bottom of the box just can be left in the top of this bullet face, make wiring hole unblocked, wire head can be inserted in the wiring hole through plug wire hole.After this unclamp the locking pad, the end of a thread locking reed in the metal connection terminal board can be upspring short oblique bullet face.The top of the oblique bullet face of this weak point just can be pushed up lock and be compressed wire head on last horizontal sidewall, and lead is contacted well with the binding post box.

The locking pad that this connecting terminal block is designed, it two presses bayonet lock pawl to be " π " shape, and its perpendicular foot dogging hangs in the square breach on the upright sidewall of metal connection terminal board.Press the alternate pressure tongue that is contacted with short oblique bullet face that is provided with between the bayonet lock pawl two, make per two cuboid hole grooves that a locking pad just be arranged.Promptly locking pad can be pressed the wire head in the metal connection terminal board in tight two the cuboid hole grooves of pintle hook lock.

Connecting terminal block of the present utility model owing to be provided with temperature control protective device, can shield to circuit.Owing to designed the locking pad, it is firmly convenient that wire head is patched, and operation is simple in wiring, is adapted to wiring operation in enormous quantities.Therefore this connecting terminal block can be widely used in going in household electrical appliances or other electric equipment products.

Embodiment of the present utility model further describes clear by accompanying drawing.A set of connections terminal board of making, it has four binding posts, and as shown in the figure: Fig. 1 is the connecting terminal block front view.Have among Fig. 1: insulating body 1, plug wire hole 5 ', last bar lid 13.Fig. 2 cuts open vertical view behind the bar lid for the binding post composition.Have among Fig. 2: insulating body 1, cuboid hole groove 2, the temperature sensor cave 4 of hanging down, opening terminal block 6, separate slot plate 7, locking pad 10, last bar covers 13.Fig. 3 is the cutaway view (the A-A view of Fig. 2) of connecting terminal block.Have among Fig. 3: insulating body 1, the cuboid hole groove 2 of band wing groove, flat cuboid metal connection terminal board 3, the temperature sensor cave 4 of hanging down, wiring hole 5 at the bottom of the box, locking reed 8, short oblique bullet face 9, last bar covers 13.Fig. 4 is the cutaway view (the B-B view of Fig. 2) of connecting terminal block.Have among Fig. 4: insulating body 1, wiring hole 5 at the bottom of the box, plug wire hole 5 ', opening terminal block 6, separate slot plate 7, locking reed 8, short oblique bullet face 9 is pressed tongue 12, last bar lid 13, temperature fuse plug 14.Fig. 5 is the structural representation of locking pad 10.Have among Fig. 5: locking pad 10, press bayonet lock pawl 11, press tongue 12.
