Embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail, so that technical staff's of the same trade understanding:

Shown in Fig. 1-5, label represents respectively: housing 100, cap 110, top board 111, perforate 112, shell block 120, lid 130, wire guide 131, connection bolt 140, entrance hole 150, electric conductor 200, efferent 210, jaw 211, input 220, connecting hole 221, output pressing line frame 300, screw 310, insulated leg 400, wire-incoming chamber 410, screw 500.

Embodiment 1:

Referring to Fig. 1-2, a kind of line branch terminal that provides in the present embodiment 1 comprises the housing 100 that is used for insulation that is comprised of cap 110 and shell block 120, is provided with electric conductor 200, output pressing line frame 300, insulated leg 500 in the housing 100.Wherein, cap 110 and cooperatively interact spiral-lock formation housing 100 relative with shell block 120 openings.

Electric conductor 200 1 ends are formed with three layers of stepped efferent that is staggered 210, and the relative other end forms input 220.The efferent 210 of electric conductor 200 is fixedly installed in the described insulation shell 500, and insulated leg 500 matches with groove on housing 100 inwalls, plays the effect of fixed bearing electric conductor 200.The input 220 of electric conductor 200 extends described housing 100 outsides.Have an assembling position that supplies connection bolt to pass through electric conductor 200 and electrically contact with electric conductor 200 on the input 220, in present embodiment 1, this assembling position is the connecting hole 221 of a circle, when needs line branch terminal and other electric devices (such as switch, circuit breaker) when being connected, at first described input 220 is inserted into wiring place of other electric devices, again connecting hole 221 is connected fastening getting final product with the terminals of other electric device wiring place with bolt, and bolt has also just consisted of above-mentioned connection bolt.This connected mode has been avoided using and has been connected wire, makes the convenient and fast connection of line branch terminal and other electric devices, and more solid and reliable.In addition, the end parts fork-shaped of efferent 210 becomes several jaws 211, and the efferent 210 on upper strata has through hole in the corresponding position of the jaw 211 of the efferent 210 in corresponding middle level.

Obviously, the connecting hole 221 in the said structure also can adopt breach or other equivalent structure to substitute, as long as can satisfy: bolt passes through electric conductor 200, bolt and electric conductor and electrically contacts, and use the assembling position that namely can be used as on the input 220.

Described output pressing line frame 300 is the hollow frame of a both ends of the surface opening, and at the top screw 310 is set.Output pressing line frame 300 is sleeved on the described jaw 211 one to one, and can slide up and down.Corresponding, screw 310 on the top board 111 at cap 110 tops on the corresponding output pressing line frame 300 is offered perforate 112, be fitted with in the perforate 112 for the screw 500 of screw bolt, the head of screw 500 jaw 211 of roughly fitting can not drop output pressing line frame 300.Take the syndeton of the output pressing line frame 300 in middle level as example, screw 500 passes through the through hole on perforate 112 and the upper strata efferent 210 successively, the screw 310 of exporting therewith on the pressing line frame 300 is threaded, turn this screw 500 during use this output pressing line frame 300 is moved up or down, to oppress wire or to unclamp wire.Because the anti-lost technology of screw 500 is those skilled in the art's technology of commonly seeing, can select based on the concrete structure of line branch terminal that the hoop mouth is anti-lost, eck is anti-lost or other anti-drop structures, so this for top board 111 on the concrete structure of perforate repeat no more.

For wire is introduced between output pressing line frame 300 and the jaw 211, insulated leg 400 is corresponding to the some wire-incoming chambers 410 for the wire turnover of output pressing line frame 300 housing interruption-formings, the position of corresponding wire-incoming chamber 410 forms entrance hole 150 one to one on the housing 100 simultaneously, wire enters line branch terminal inside from entrance hole 150, insert between output pressing line frames 300 and the jaw 211 by wire-incoming chamber 410, and wire-incoming chamber 410 is connected the effect that the output lead that is connected with each jaw 211 is isolated mutually of playing with entrance hole.In present embodiment 1, the aperture of wire-incoming chamber 410 is greater than the diameter of wire, so that the not wire stripping of wire partly passes in and out.Corresponding, entrance hole 150 also needs to satisfy the not wire stripping of being convenient to wire and partly passes in and out.Adopt this kind structure make wire only the part of line ball need to by peeling, reduce wire and be exposed to airborne length.

Embodiment 2:

Referring to Fig. 3-5, the difference of present embodiment 2 and embodiment 1 is that described electric conductor 200 is arranged in the described housing 100, and adopts a connection bolt 140 to be connected with other electric equipments.And line branch terminal need to support the use with the wire with connecting ring in the present embodiment 2.Its concrete set-up mode is as follows:

Electric conductor 200 is installed on the insulated leg 400, and recessed hole of formation on this insulated terminal 400, the head of connection bolt 140 embeds in this hole to be fixed, connection bolt 140 passes through the connecting hole 221 on the input 220 of electric conductor 200, and and electric conductor 200 contact of fitting realize conduction between the two.And also comprise a lid 130 on the described housing 100, the detachable connection between this lid 130 and the cap 110, cap 110 is at the breach of one of the outside of connection bolt 140 formation and lid 130 form fit specifically, the outer rim of this breach has snap fit, and the outer rim of lid 130 is provided with draw-in groove, and snap fit and the concavo-convex cooperation of draw-in groove realized the fixing of the two when lid 130 was assemblied on this breach in correspondence.In addition, also form a wire guide 131 on the described lid 130, draw for wire.

When the input wiring, only need lid 130 is pulled down, connecting ring is sleeved on the connection bolt 140, be pressed on the electric conductor 200 by nut, can realize the conductive communication between the two, then wire is drawn and loads onto lid 130 from wire guide 131.After taking off lid 130 during dismounting connecting ring is removed from connection bolt 140, namely finish the dismounting of the two.

Obviously, those skilled in the art also should be appreciated that, connecting hole 221 in the said structure can adopt breach or other equivalent structure to substitute equally, because connection bolt 140 is fixed on the insulated leg 400, so as long as can satisfy: make connection bolt 140 pass through electric conductor 200, connection bolt 140 and electric conductor and electrically contact, use the assembling position that namely can be used as on the input 220.

The utility model one of ordinary skill in the art be appreciated that; the above embodiment of the present invention only is one of preferred embodiment of the present utility model; be the length restriction; here can not all execution modes of particularize; any enforcement that can embody the utility model claim technical scheme is all in protection range of the present utility model.

It should be noted that, above content is in conjunction with concrete execution mode further detailed description of the utility model, can not assert that embodiment of the present utility model only limits to this, under the guidance of above-described embodiment, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, as: the selection for assembling position setting position in above-described embodiment, also not only be confined to can only arrange on the input 220, it can be arranged on the efferent 210 equally; And the connection bolt among the embodiment 2 140 also can select to adopt the mode that directly is fixed on the housing, and these improvement or distortion drop in the protection range of the present utility model.
