Abstract

The utility model discloses a waterproof junction box. The waterproof junction box comprises a pedestal and an upper cover. A cover edge of the upper cover is provided with a sealing groove. A sealing ring is arranged between the upper cover and the pedestal. The upper cover and the pedestal are fixedly connected through a fixed screw. A sidewall of the pedestal is provided with a knocked-down hole. The knocked-down hole forms sealing connection before being knocked down. A bottom of the pedestal is provided with an installation pin. The installation pin is provided with an installing hole. An inner bottom surface of the pedestal is provided with a fixed column. The fixed column is provided with a fixed hole. By using the waterproof junction box of the utility model, the sealing ring is arranged between the upper cover and the pedestal and the knocked-down hole forms the sealing connection before being knocked down so that an internal portion of the junction box is in a sealing state and waterproof protection is provided for a cable joint in the junction box.

Description

A kind of waterproof junction box

Technical field

The utility model belongs to the lighting fitting field, is specifically related to a kind of waterproof junction box.

Background technology

Illuminator is the most basic system in daily electricity consumption, applies very extensive.Electric pressure and current class that general distribution system is used all are not quite similar, to such an extent as to the cable model of using also is not quite similar.In terminal electrical appliance process from the distribution system to the illuminator, can use different cables and be connected.Illuminating lamp for different electric pressures and different capacity also can be used different cables simultaneously.Particularly, when product is applied to different countries, because used cable standard is different, cause the cable of required connection varied.The distribution system cable, in the terminal electrical appliance process of illuminator, need to carry out the cable connection, in order to improve the fail safe of cable joint, generally all adopts cable straight joint.When cable joint is positioned at open-air condition, also need to use waterproof junction box, in order to protect outdoor cable joint.To these, different application scenarios is all to use different cable straight joints at present, makes terminal box of a great variety, and the production management cost is larger.

The utility model content

A kind of waterproof junction box that the utility model provides for above-mentioned weak point, can, for different cables, provide waterproofing protection in the place of cable joint.

The utility model is achieved in that a kind of waterproof junction box, comprises base, upper cover, and the cover rim of upper cover arranges seal groove, between upper cover and base, sealing ring is set, and upper cover is fixedly connected with by hold-down screw with base; Base side wall also arranges knock down hole, before the knock down hole abate, is and is tightly connected, and the base bottom arranges installation foot, and installing hole is set on installation foot; The base inner bottom surface arranges fixed leg, and fixing hole is set on fixed leg.

As preferably, the knock down hole of waterproof junction box base side wall of the present utility model setting is 1～8.It is 2～8 that the base inner bottom surface arranges fixed leg.For convenience of waterproof after stube cable, the anti-head of installing cables after the knock down hole abate.Install and fix for convenience of terminal box, two ends, base bottom respectively arrange one of installation foot, 1～3 of installing hole are set, installing hole diameter 3～8mm on every installation foot.

Waterproof junction box of the present utility model, arrange sealing ring between upper cover and base, is before the knock down hole abate and is tightly connected simultaneously, makes terminal box inter-process sealing state, for the cable joint inside terminal box provides waterproofing protection.The knock down hole arranged on base side wall, the knock down hole dimensions can be according to the standard formulation in country variant area, in order to adapt to various criterion.After the knock down hole abate, the cable waterproof head of different size can be installed, in order to meet the cable of different size.The base inner bottom surface arranges fixed leg, and fixing hole is set on fixed leg, can the binding post of different size be installed in waterproof junction box, in order to facilitate stube cable.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail; but the utility model is not limited to following execution mode; any change of making on the present embodiment principle or replacement scheme, all fall among the claimed scope of the utility model.

1 arrive Fig. 5 by reference to the accompanying drawings, a kind of waterproof junction box, comprise base 4, upper cover 5, and the cover rim of upper cover 5 arranges seal groove, between upper cover 5 and base 4, sealing ring 9 is set, and upper cover 5 is fixedly connected with by hold-down screw 7 with base 4; Base 4 sidewalls also arrange knock down hole 3, before knock down hole 3 abates, are and are tightly connected, and base 4 bottoms arrange installation foot 2, and installing hole 6 is set on installation foot 2; Base 4 inner bottom surfaces arrange fixed leg 8, on fixed leg 8, fixing hole are set.

As preferably, the knock down hole 3 of waterproof wiring box base 4 sidewall settings of the present utility model is 1～8.It is 2～8 that base 4 inner bottom surfaces arrange fixed leg 8.For convenience of waterproof after stube cable, the anti-head 1 of installing cables after knock down hole 3 abates.Install and fix for convenience of terminal box, base 4 two ends, bottom respectively arrange 2 one of installation feet, and it is 1～3 that installing hole 6 is set on every installation foot 2, installing hole 6 diameter 3～8mm.

When in use, according to the installation situation needs, relevant position knock down hole 3 is knocked out, after knock down hole 3 abates, form cable-through hole, install cable waterproof head 1, the cable that needs are connected is by cable waterproof head 1 access waterproof junction box.Binding post in order to stube cable is fixed on fixed leg 8, and by the fixing hole on fixed leg 8, binding post can be screwed.Different binding posts can be installed as required.Between upper cover 5 and base 4, sealing ring 9 is set, can effectively prevents that outside water from entering terminal box inside.The knock down hole 3 that base 4 sidewalls are set is and is tightly connected before abate, and knock down hole 3 dimensionss can be according to the standard formulation in country variant area, in order to adapt to various criterion.After knock down hole 3 abates, the cable waterproof head 1 of different size can be installed, in order to meet the cable of different size.Also can, as required at the one or more knock down holes 3 of abate, the cable of varying number be installed.
