Preferably, the screw head has cap, cap cap central tube end, and center tube end is equipped with supply lines insertion Shallow slot, shallow slot and electric wire side view cooperate.

By using above-mentioned technical proposal, sealing effect can be improved, prevent toy from entering central tube.

Preferably, the shallow slot depth is less than the diameter of wire.

By using above-mentioned technical proposal, electric wire can avoid the generation in gap, improve after being crushed out of shape full of shallow slot Leakproofness.

Preferably, seal washer is pressed between the cap and center tube end.

By using above-mentioned technical proposal, the waterproof sealing effect of central tube is further improved.

Preferably, a pair of conductive body is equipped in the central tube, core junction is pressed between a pair of conductive body, central tube Side is communicated, branch pipe internal plug has the briquetting for compressing electric conductor inside branch pipe and central tube integrally formed with branch pipe.

By using above-mentioned technical proposal, core junction is compressed using two panels electric conductor, further improves two The bonding strength and stability of electric wire connection, moreover it is possible to avoid core junction poor contact caused by shaking.

Preferably, the central tube side is equipped with a pair of branch pipe communicated.

By using above-mentioned technical proposal, protrude into briquetting from two branch pipes of central tube two sides, can fast and stable by line Core junction compresses.

In conclusion the utility model has the following beneficial effects:

Bonding strength, the stability of the connection of two electric wire cores are not only increased, also there is protection against rodents worm to bite, the function of waterproof Can, it is not easy open circuit, short circuit.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment 1

A kind of wire connector, as shown in Figure 1 and Figure 2, the central tube 1 directly grown including one, 1 inner cavity of central tube is cylinder Shape can cooperate with cylindrical screw.Central tube 1 is built-in with electric conductor 2, and electric conductor 2 is made of such as copper for conductive material, two electric wires 7 ends strip out to protrude into from 1 both ends of central tube after core and contact with electric conductor 2.Electric wire 7 is taken out out of central tube 1 first, is then existed 1 both ends tapping thread of central tube, then protrudes into central tube 1 for electric wire 7, screws on screw 3 then at 1 both ends of central tube, screw 3 advances It will push the advance of electric wire 7 in the process, so that core be made to come into full contact with electric conductor 2.Central tube 1 be can slight deformation plastics Electric wire 7 is extruded on 1 inner wall of central tube by pipe, screw 3, squeezes into gel or instillation in the gap of screw 3 and 1 inner wall of central tube The sealing material as filling such as wax.It should be noted that screw 3 is not contacted with the core of electric wire 7 and electric conductor 2.

As shown in Figure 1, to further increase sealing waterproofness there is the screw 3 of cap 31 at the top of use, during screw 3 is screwed into When in heart pipe 1, cap 31 presses 1 end of central tube.

As shown in figure 3, drawing for convenience of electric wire 7, it is shallow less than 7 diameter of electric wire that 1 end of central tube offers a depth Slot 11, electric wire 7 are directly embedded into shallow slot 11 when drawing, and do not influence compression of the cap 31 (see Fig. 1) to 1 end of central tube of screw 3. Shallow slot 11 can be formed with pocket knife interim processing, and because 7 thickness of electric wire is different, scene processing can be convenient for control 11 size of shallow slot and electric wire The cooperation of 7 side views.

As shown in Fig. 2, can also cover seal washer 4 on screw 3, when tightening screw 3, seal washer 4 is pressed in cap 31 Between 1 end of central tube.

Embodiment 2

A kind of wire connector, as shown in figure 4, unlike the first embodiment, 1 two sides of central tube are respectively integrally formed with one Root branch pipe 5, two branch pipes 5 are symmetrical about central tube 1 and communicate with central tube 1, and this two branch pipes 5 are coaxial, are placed in center Electric conductor 2 in pipe 1 shares two pieces, and is placed in branch pipe 5 and communicates place with central tube 1, and briquetting 6 is filled in two branch pipes 5 or is attacked Enter screw, pushes electric conductor 2 to centre opposite to each other, the junction of 7 core of electric wire can be pressed between two pieces of electric conductors 2, really Stable contact is protected.It is located at structure not visible in central tube 1 in Fig. 4 to be shown in broken lines.

The above embodiments are only the explanation to the utility model, are not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
