Description

The junction box

Technical field

The utility model relates to a kind of junction box.

Background technology

Along with the raising of people's living standard, various home electronic appliance products more and more enter into people's family.When these products enter in the people family, during various cables also more and more are access in and get home, for example cable TV, telephone wire, entryphone or the like.But this increasing cable not only can influence attractive in appearance in the family, also stays potential safety hazard sometimes.Therefore, the junction box who is specifically designed to wiring just arises at the historic moment.Junction box inside is provided with installing rack, and various functional modules can be installed, and various cables here gather, and divides the various piece in getting home then.

Existing junction box as shown in Figure 1, comprise at the bottom of the case 1, box-frame 6 and an installing rack 3, box-frame 6 is installed at the bottom of the case on 1, cable can enter at the bottom of the case 1 by the line hole 11 on 1 at the bottom of the case, after all being connected to the joint of cable on the installing rack 3, with screw installing rack 3 is installed at the bottom of the case 1 inside, then as shown in Figure 2, chamber door is built.

Though this junction box has solved the wiring problem of cable, but because after the logical cable-through hole of cable enters at the bottom of the case, all wiring operations are all carried out at the back side of installing rack, therefore in the time of each installation and maintenance, all installing rack to be pulled down, be not easy to very much operation, thereby make operating efficiency low.

It is CN200944516Y that creator of the present invention afterwards works out a kind of Chinese patent notification number, the day for announcing is the junction box on September 5th, 2007, this junction box's structure as shown in Figure 3, comprise at the bottom of the case 1, box-frame 6 and

chamber door

2,1 is provided with the line hole at the bottom of the case, box-frame 6 is installed at the bottom of the case on 1, and chamber door 2 is installed on the box-frame 6, also comprise an installing rack 3, installing rack 3 is provided with the frame 4 of sunkening cord, and a sideway swivel of installing rack is connected to the inboard of box-frame 6.The junction box of said structure operates by the structure of rotation, and is simple in structure durable, and is convenient to the installation and maintenance of inside cable, improved operating efficiency greatly.

But above-mentioned junction box's box-frame 6 adopts integrated design, screw 7 by side is fixed at the bottom of the case on 1, this structure is side mounting screw inconvenience at first, secondly it is not attractive in appearance that screw is directly exposed to the outside yet, in view of this, creator's further investigation of the present invention has been done further improvement to this junction box's box-frame structure.

The utility model content

Technical problem to be solved in the utility model provides a kind of junction box, and simple in structure being convenient to safeguard, and attractive and durable, easy for installation.

For solving the problems of the technologies described above, the utility model provides a kind of junction box, at the bottom of comprising case, box-frame and chamber door, wired hole at the bottom of the case, on box-frame is installed at the bottom of the case, and chamber door is installed on the box-frame, and box-frame comprises limit cover and frame frame, frame fixation is at the bottom of the case, and the limit lid is installed on the framework and covers the connector of frame fixation at the bottom of the case.

The utility model is by above-mentioned detachable box-frame structure, and is easy for installation also both artistic and practical.
