Abstract
The invention provides a junction box, which comprises a box body, terminals positioned in the box body, and cables extending into the box body and electrically connected with the terminals. The box body comprises side walls and a front wall connected with the side walls. Joints are protruded forward from the front wall and are integrally formed with the front wall, the joints are provided with through holes which are communicated with the inside of the box body, and the through holes are provided with openings for allowing the cables to be inserted in. The joints are protruded forward from the front wall and are integrally formed with the box body, so no clearance exists at the joint parts of the joints and the front wall, and accordingly water vapour is prevented from entering.

Therefore, be necessary to provide a kind of new terminal box to overcome the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of effectively terminal box of waterproof.
Correspondingly, a kind of terminal box of the present invention, comprise box body, be positioned at the terminal of box body inside and extend into the inner cable that is electrically connected with terminal of box body, described box body comprises sidewall and connects the antetheca of sidewall, described antetheca one is equipped with forward joint, this joint is provided with the through hole that communicates with box body inside, and through hole is provided with the opening that inserts for cable.
As a further improvement on the present invention, be connected with reinforcement between described joint and the sidewall.
As a further improvement on the present invention, described joint has external screw thread.
As a further improvement on the present invention, be provided with step surface in the described through hole, form container cavity between described opening and the step surface, described container cavity contains plug and the interior pawl that cooperatively interacts.
As a further improvement on the present invention, described plug comprises the pressure section that is held in described step surface and the socket part that is socketed for described interior pawl.
As a further improvement on the present invention, described interior pawl comprises and is socketed in the main part on the described socket part and is positioned at the claw that open outer side is radially outwards opened.
As a further improvement on the present invention, described plug is made by elastomeric material.
As a further improvement on the present invention, described interior pawl is made by flexible plastic material.
As a further improvement on the present invention, also comprise tapped back cover, described back cover is connected with joint screw thread.
As a further improvement on the present invention, back cover is in rundown process, and the claw inward collapsible of interior pawl is with clamping cables.
The invention has the beneficial effects as follows: joint is outstanding and one-body molded with box body forward from antetheca, can not produce the slit at joint and antetheca joint, thereby prevent that steam from entering.
Description of drawings
Fig. 1 is the stereogram of an embodiment of the present invention terminal box;
Fig. 2 is the decomposed figure of terminal box shown in Figure 1;
Fig. 3 is the three-dimensional structure diagram of box body among Fig. 1.
Embodiment
Describe the present invention below with reference to each execution mode shown in the drawings.But these execution modes do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in protection scope of the present invention.
As shown in Figure 1, an embodiment of the present invention terminal box comprises box body 1, is contained in some terminals (not shown) of box body 1 inside and extends into the box body 1 inner cable 2 that is electrically connected with terminal.
As shown in Figures 1 to 3, box body 1 comprises sidewall 11 and connects the antetheca 12 of two side, antetheca 12 is equipped with forward joint 121, this joint 121 and box body 1 integrated injection molding, joint 121 is provided with the through hole 123 that communicates with box body inside, this through hole 123 has the opening 124 towards the outside, and it is inner and be electrically connected with terminal that cable 2 stretches into box body from opening 124 by through hole 123.Between joint 121 and sidewall 11, be connected with reinforcement 111 in order to the intensity of reinforced joint 121.Because joint 121 protrudes from antetheca 12, opening 124 will can not be formed at away from antetheca 12 outer surface of antetheca 12, and joint 121 can not produce the slit with the joint of antetheca 12 like this, and steam also just can't enter.In addition, joint 121 is provided with external screw thread.
Through hole 123 is provided with the container cavity 125 near opening 124, and the bottom of container cavity 125 is provided with step surface 126.That is, container cavity 125 is between opening 124 and step surface 126.For anti-sealing enters from opening 124, contain plug 3 and interior pawl 4 in the container cavity 125.Plug 3 is made by elastomeric material, and is corrosion-resistant and ageing-resistant, comprises pressure section 31 and socket part 32, and preferably, pressure section 31 all is hollow cylindrical and coaxial with socket part 32, and the diameter of socket part 32 is slightly less than pressure section 31 diameters.Interior pawl 4 is made for flexible plastic material, has good toughness, is difficult for fracture.Preferably, interior pawl adopts nylon PA66 material to make.Interior pawl 4 has some claws 42 that main part 41 and autonomous body 41 1 ends radially outwards open.In the specific operation process, at first the main part 41 with interior pawl 4 is enclosed within on the socket part 32 of plug 3, then with both together in opening 124 is filled in container cavity 125, until the pressure section 31 of plug 3 is held in step surface 126, at this moment, the claw 42 of interior pawl 4 is positioned at outside the opening 124.At this moment cable 2 can enter box body inside by interior pawl 4, plug 3, through hole 123, at last a back cover 6 with internal thread is enclosed within on the cable 2, and be connected with joint 121 by screw thread, back cover 6 is in being screwed into process, thereby the claw of interior pawl 4 42 inward collapsible clamping cables 2 prevent that it breaks away from box body 1 because of external force.
Center tap of the present invention is outstanding and one-body molded with box body forward from antetheca, can not produce the slit at joint and antetheca joint, thereby prevent that steam from entering.
Be to be understood that, although this specification is described according to execution mode, but be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each execution mode also can through appropriate combination, form other execution modes that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility execution mode of the present invention; they are not to limit protection scope of the present invention, allly do not break away from equivalent execution mode or the change that skill spirit of the present invention does and all should be included within protection scope of the present invention.
