Abstract

The utility model discloses a wire connection box, which comprises a box body, the surrounding of which is arranged with a plurality of input and output holes of the transmission line, two corresponding edges of the upper end of the box body are arranged with bolt holes for the installation of electric components. The characteristics are that the bottom surface of the box body is arranged with installation joint protruding outwards and a connection rod used to limit the location of the wire connection box can be inserted in the installation joint. The input and output holes of the box body have the same number and relative position on the symmetric edges. Multi input and output transmission lines can be accessed because the utility model is a multi input and multi output wire connection box with installation joint, the connection rod is used to limit the installation location of the wire connection box to make the position right when the wire connection box is installed. Material used by the utility model is refractory flame retardant insulating material, the use of which is safe, the structure of the box is simple and practical, the cost is cheap and the market prospect is broad.

Description

A kind of terminal box

Technical field:

The utility model relates to a kind of connector that circuit connects that is used for, and the terminal box of erection joint is exported and had to specifically a kind of multichannel input, multichannel.

Background technology:

As everyone knows, extend to user's subscriber's line, generally all connect up by some cables being linked together in some joints from telephone office.Cable wherein can be copper cable and the fiber optic cables with different length and diameter.When the cable joint on the subscriber's line was exposed in the external environment, copper cable may be corroded lamentedly or ruptures because of moisture content, has influence on its contact performance.Simultaneously, when the optical fiber of cable is when making with glass, the fiber optic cables in above-mentioned state will fortunately have high corrosion resistance.Yet the hydrogen that produces in hydrolytic process will infiltrate optical fiber, thereby make the optical fiber generation not wish the optical loss that occurs.At this on the one hand, no matter be the cable of what kind, its joint all needs to protect with terminal box.Terminal box also needs to have the function that the cable and the terminal box of connection mechanically can be connected together, and prevents that thus cable from separating with terminal box suddenly.

Since during construction and installation terminal box leave a blank all greatlyyer in advance, terminal box all can stay very big space when mounted, terminal box is not only installed inconvenience like this, range estimation can only be leaned in the position, and is extremely lack of standardization.And be difficult to fixedly secure.

The utility model content:

The purpose of this utility model be to provide a kind of can the protection circuit interface multichannel input, multichannel output and have the terminal box of erection joint.

To achieve these goals, the technical solution of the utility model is such, a kind of terminal box, comprise box body, be provided with a plurality of circuit inputs, delivery outlet around the box body, two corresponding sides places of box body upper end are provided with the bolt hole that electric elements are installed, and it is characterized in that, the bottom surface of described box body is provided with outwards outstanding erection joint, can insert the extension bar in order to restriction terminal box position in described erection joint.

Described erection joint is circular.

The circuit input of described box body, delivery outlet, number is identical on symmetrical limit, and the position is relative.

Four limits, outside of described terminal box are the right angle transition, and sound construction is durable.

Four limits, outside of described terminal box are round-corner transition, reach convenient and practical effect attractive in appearance.

A kind of terminal box of the utility model is the terminal box that multichannel is imported, erection joint is exported and had to multichannel, can insert input, output multi-path line.Adopt extension bar to limit the installation site of terminal box, can make terminal box when mounted, correct position.The material that the utility model adopted is the fire resistant flame retardant insulating material, and is safe in utilization; Box body structure is simple and practical, and is with low cost, and market prospects are big.

Description of drawings:

Describe the utility model in detail below in conjunction with the drawings and specific embodiments,

Fig. 1 is the external structure schematic diagram of a kind of terminal box of the utility model;

Fig. 2 is the vertical view of a kind of terminal box of the utility model;

Fig. 3 is the upward view of a kind of terminal box of the utility model.

Embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

Referring to Fig. 1, Fig. 2, Fig. 3, a kind of terminal box, comprise box body 1, described box body 1 is the rectangle box body, 1 liang of long limit of box body respectively is provided with four circuit input holes 11, two minor faces respectively are provided with two circuit delivery outlet 11a, and each input hole 11, delivery outlet 11a block with dust protection with shutoff before use and enter.If use certain input hole 11, delivery outlet 11a, the shutoff of input hole 11, delivery outlet 11a can be dismantled gets final product.Two corresponding sides places of box body 1 upper end are provided with the bolt hole 12 of installation, so that electric elements are installed.An outwards outstanding erection joint 13 is set in the bottom of box body 1, and erection joint 13 be a circle, inner hollow, and be not communicated with box body 1 inside; During installation extension bar is installed on the joint 13, can limits the terminal box installation site.

Box body 1 and lid 2 all adopt the corrosion-resistant fire proofing of insulation, can prevent electric leakage during use, and be aging etc.

Although the foregoing description is described the utility model, for the technical staff of the industry, still can do multiple variation to present embodiment, therefore, every employing similar variation of the present utility model all should be listed protection range of the present utility model in.

Claims
