Watertight junction box

Description

[0001] The present invention relates to junction boxes and more particularly to a watertight junction box, which facilitates rapid installation of wires and effectively prevents the permeation of water.

[0002] When connecting two electric wires together, the most commonly used method is to cut off the outer insulation of the connection end of each of the two electric wires, then to twist the bare metal conductors of the two electric wires together, and then to wrap the connection between the two electric wires with an insulative tape. Further, a junction box may be used for the connection of two electric wires.

[0003] US 5,499,931 discloses a lamp conducting structure in which power wires are pressed by the lower frame top central cylinder to cause the conductive metal clip sharp needle to cut off the outer insulations of the power wires to contact with the metal part of the power wires. This design is for indoor application, allowing the lamp to be easily connected with power wires of different thickness. However, this design cannot prevent the permeation of water. When used outdoor, rainwater may leak in, resulting in oxidation of the conductive metal clip sharp needle and shortening the work life.

[0004] GB 691802 A (see Figures 1-5) relates to an interconnector for a main and a branch insulated cable which comprises an insulating body 8 having coaxially-extending walls 9, 10 with diametrically-opposed slots 13, 14. Part of a main cable 6 lies between the wall 9 and a screw-cap 11, and part of a branch cable 7 lies between the wall 10 and a screw-cap 12, the inner ends of slots 13, 14 being grooved to receive the cables. Two metal plates 17, 18 are secured to the body by screws 19 with contact-points 20, two similar plates 21, 22 being secured by screws 23 with contact-points 24, two similar plates 21, 22 being secured by screws 23 with contact-points 24, A resistor 25 is connected between the plates 17, 22 and a resistor 26 between 18, 21. On screwing down the cap 11 the main cable 6 is pierced by points 20, the branch cable 7 being pierced by points 24 on screwing down the cap 12, one conductor of each cable now being connected together by the resistor 25, and the other two by resistor 26. The space round the contacts may be filled with a sealing compound, and securing lugs provided for the device. In other embodiments the resistors are replaced by inductors or capacitors which act as filters. When coaxial cables are used, the inner part of the contact-pins may be coated with a ceramic, and when the outer conductor is thick a hole may be drilled in it to enable the point to contact the inner conductor.

[0005] The present invention has been accomplished according to claim 1, under the circumstances in view. It is one object of the present invention to provide a watertight junction box, which utilizes a piece of silicon rubber to wrap about the connection area between the copper contacts and the installed power wire, protecting the copper contacts against oxidation and assuring a long service life and conductive stability.

[0006] It is another object of the present invention to provide a watertight junction box, which utilizes a piece of silicon rubber to assure watertight sealing and allows repeated use of the junction box without lowering its watertight sealing function.

[0007] As shown in FIGS. 1-5, a watertight junction box in accordance with the present invention comprises a box body 1, a lower floating plate 2, an upper floating plate 3, a holding down plate 4a or 4b and a lock cap 5.

[0008] The box body 1 is a hollow member comprising a threaded neck 11, an opening 12 transversely cut through the threaded neck 11 to separate the threaded neck 11 into two symmetrical halves, an accommodation chamber 13 defined beneath the threaded neck 11 (see FIG. 2 and FIG. 3), an insertion hole 14 cut through one side of the accommodation chamber 13 for the insertion of a modular cable 6 into the accommodation chamber 13, a partition board 15 disposed inside the accommodation chamber 13 (see FIG. 3 and FIG. 4), two copper contacts 16 mounted in the accommodation chamber 13 at two sides relative to the partition board 15 and a plurality of ribs 17 located on the inside wall of each of the two symmetrical halves of the threaded neck 11. Further, each copper contact 16 has a plurality of sharp top protrusions 161. After the modular cable 6 is inserted into the insertion hole 14, the copper contacts 16 are respectively forced with the bottom edges thereof into contact with the (conductors of the) modular cable 6, and then a resin glue 18 is filled in the accommodation chamber 13 so that the connection between the sharp copper contacts 16 and the modular cable 6 is embedded in the hardened resin glue 18 (see FIG. 6).

[0009] The lower floating plate 2 is a flat plate having two through holes 21 for the copper contacts 16 to pass through, two bottom legs 22 diagonally disposed at the bottom side and two springy supporting strips 23 diagonally disposed at the top side. The lower floating plate 2 is inserted into the accommodation chamber 13 of the box body 1 (see FIG. 5), enabling the two bottom legs 22 to be embedded in the resin glue 18 (see FIG. 6).

[0010] The upper floating plate 3 is a flat plate having two through holes 31 corresponding to the through holes 21 of the lower floating plate 2 for the copper contacts 16 to pass through and two notched side edges 32 fitting the ribs 17. The upper floating plate 3 is set inside the threaded neck 11 above the lower floating plate 2. Further, a suitable amount of silicon rubber 7 is filled in the accommodation chamber 13 in between the lower floating plate 2 and the upper floating plate 3 (see FIG. 6).

[0011] The holding down plate 4a or 4b is selectively used depending upon the thickness of the external electric wire 8a or 8b to be connected. The holding down plate 4a or 4b is a flat clamping plate having a substantially-shaped cross section and a vertical groove 42a or 42b on each of the two opposite lateral sidewalls 41a or 41b thereof for receiving one of the ribs 17 at each of the two symmetrical halves of the threaded neck 11.

[0012] The lock cap 5 is a screw cap for threading onto the threaded neck 11 of the box body 1, having an inside stop wall 51 that curves inwards (see FIG. 7 or FIG. 8).

[0013] The box body 1, the lower floating plate 2, the upper floating plate 3, the holding down plate 4a or 4b and the lock cap 5 are assembled to form the desired watertight junction box. As stated above, a certain amount of soft rubber, in particular silicon rubber 7, is filled in the accommodation chamber 13 in between the lower floating plate 2 and the upper floating plate 3. During installation, the external power wire 8a or 8b to be connected is set in opening 12 of the box body 1 and transversely extended through the threaded neck 11 and kept between the holding down plate 4a (or 4b) and the upper floating plate 3, and then the lock cap 5 is threaded onto the threaded neck 11 of the box body 1. When threading the lock cap 5 onto the threaded neck 11 of the box body 1, the inside stop wall 51 is forced downwardly against the holding down plate 4a (or 4b), causing the sharp top protrusions 161 of the copper contacts 16 to pierce the outer insulation 81 a or 81 b of the external power wire 8a or 8b (see FIG. 8 or FIG. 10) and to contact the respective conductors in the external power wire 8a or 8b. At this time, the silicon rubber 7 is compressed to seal the contact area between the copper contacts 16 and the external power wire 8a or 8b (see FIG. 8), thereby protecting the copper contacts 16 against oxidation and corrosion and achieving excellent watertight sealing effects.

[0014] The silicon rubber 7 is an elastic material that is able to return to its former shape after being pulled or pressed. After the external power wire 8a or 8b is removed, the silicon rubber 7 immediately returns to its former shape, filling up the space in the accommodation chamber 13 in between the lower floating plate 2 and the upper floating plate 3. Therefore, the watertight junction box of the present invention can be used repeatedly without lowering its watertight sealing function.

[0015] The holding down plate 4a or 4b is selectively used depending upon the thickness of the external power wire 8a or 8b to be connected. These two holding down plates 4a and 4b have the same structural design with the exception of the gap width between the two opposite lateral sidewalls 41a or 41b. For example, FIG. 9 shows a thinner external power wire 8b installed in the watertight junction box.

[0016] The modular cable 6 is an electrical cable having a modular connector, for example, modular jack 61 at its one end. The other end of the modular cable 6 is inserted through the insertion hole 14 into the accommodation chamber 13 with the two bare conductors separated by the partition board 15 and respectively held down in the accommodation chamber 13 by the copper contacts 16 and sealed by the resin glue 18. Due to the sealing effect of the resin glue 18, the connection between the copper contacts 16 and the modular cable 6 is assured. Further, the box body 1 has two locating grooves 19 defined in the accommodation chamber 13 at two sides relative to the partition board 15 for receiving the copper contacts 16 respectively.

[0017] The main feature of the present design is the filling of the silicon rubber 7 in the accommodation chamber 13. When the two copper contacts 16 pierce the outer insulations 81a or 81b and come into contact with the respective conductors 82a or 82b (see FIG. 8 or FIG. 10), the silicon rubber 7 is compressed and deformed to protrude over the through holes 31 of the upper floating plate 3 and to wrap about the contact area between the copper contacts 16 and the conductors 82a or 82b of the external power wire 8a or 8b, thereby protecting the copper contacts 16 against oxidation and corrosion and achieving excellent watertight sealing effects. Therefore, the invention prolongs the work life of the junction box and assures conductive stability.

[0018] Further, one single-piece hollow member may be used to substitute for the lower floating plate 2 and the upper floating plate 3 for holding a suitable amount of silicon rubber 7 for allowing the silicon rubber 7 to be compressed and deformed to wrap about the connection area between the copper contacts and the conductors of the external power wire, achieving excellent watertight sealing effects.

[0019] In summary there is disclosed a watertight junction box including a box body 1, a lower floating plate 2, an upper floating plate 3, a lock cap 5, a modular cable 6 inserted into the box body 1 and kept in contact with sharp copper contacts 16. a holding down plate 4a or 4b for holding down an external power wire 8a or 8b on the upper floating plate 3 to cause electric contact between the external power wire 8a or 8b and the sharp copper contacts, 16 and a predetermined amount of silicon rubber 7 filled in between the lower and upper floating plate 3 that is deformed to wrap about the connection area between the sharp copper contacts 16 and the external power wire 8a or 8b when the lock cap 5 is tightly fastened to the box body 1 to force down the holding down plate 4a or 4b.
