Abstract
The invention relates to a connecting device, in particular to a junction box. The junction box comprises a box body, a box cover and an electric conduction piece, wherein trapezoid limiting grooves are formed inside the box body, insertion openings are formed outside the trapezoid limiting grooves, and the box cover and the box body are respectively provided with spiral grooves. The electric conduction piece comprises a main frame and branch frames, wherein a wire clamping groove is formed in the tail end of the main frame, and each branch frame is provided with a B type electric conduction insertion piece. The trapezoid gradient of the trapezoid limiting grooves ranges from 45 degrees to 60 degrees. The number of the branch frames is 4, and the inclination angle of the branch frames ranges from 15 degrees to 30 degrees. The insertion openings are rectangular, the distance between each insertion opening and the corresponding electric conduction insertion piece ranges from 4 cm to 7 cm, and the insertion end of each insertion opening is concave. Limiting roofs are arranged on the box cover, and the limiting roofs correspond to the trapezoid limiting grooves one to one. The junction box has a good insulating effect, and is quite firm and safe.
Description
Technical field
The present invention relates to a kind of connection device, be specifically related to a kind of terminal box.
Background technology
Terminal box is one of electrician's auxiliary material, in indoor and outdoor decoration engineering, or in architectural engineering, electric wire used is through conduit, and conventionally adopt terminal box as the effect of the transition being electrically connected between electric wire and electric wire at the joint area (such as circuit is long, or conduit is wanted corner) of electric wire.Conduit is connected with terminal box, and the electric wire of spool the inside links up in terminal box, and terminal box plays protection electric wire and the effect that is connected electric wire.Terminal box on the market has box body and the lid that loads electric wire conventionally, and box body is connected with the mode of lid by engaging, with the electric wire that needs are connected, is fixed in terminal box.Yet the box body of existing terminal box and the connected mode of lid are divided into two kinds haply.A kind of is that box body and lid can be separated completely the in the situation that of dismounting, box body is connected with the buckle of lid by its side, but owing to being all that point-to-point buckle connects, make the connection between box body and lid insecure, be easily out of shape or be separated from each other.Therefore there is another follow-on terminal box, its box body and lid one side is separately fixed together, both can not be completely separated, only have one end to be separated from each other, conventionally box body and lid in one end that can be separated, be provided with the buckle assembly that cooperatively interacts and fasten, so that can be installed together.But the terminal box of the type can not be well fixing within it by electric wire, stability is inadequate.
Therefore, urgently the terminal box of a kind of high fastness and high security, overcomes above-mentioned defect.
Summary of the invention
The object of the invention is the just defect of above prior art, a kind of terminal box is provided.
Object of the present invention can be achieved through the following technical solutions.
A terminal box, comprises box body, lid and conducting strip, and described box body inside is provided with trapezoidal stopper slot, and the outside of described trapezoidal stopper slot is provided with insert port, and described lid and box body are all provided with bolt slot.
Described conducting strip comprises body frame and support, and the end of described body frame is provided with wire draw-in groove, and described support is all provided with B shape conductive insert.
The trapezoidal gradient of described trapezoidal stopper slot is at 45 °-60 °.
Described support is provided with 4, and the angle of inclination of support is 15 °-30 °.
Described insert port is rectangle, and is 4-7cm apart from the distance of B shape conductive insert, and the insertion end of insert port is made as matrix.
On described lid, be all provided with spacing top board, and each spacing top board is corresponding one by one with each trapezoidal stopper slot.
Beneficial effect of the present invention is.
1 by adopting trapezoidal stopper slot, makes conducting strip easier for installation, more firm after installing, and avoids because rocking of conducting strip produces loose contact, thereby affect the normal work of element.
2 by adopting matrix insertion groove, and insert port is 4-7cm apart from the distance of conducting strip, improved the insulation effect of terminal box, thereby improved the useful life of terminal box.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
Fig. 2 is the partial enlarged drawing of the conducting strip shown in Fig. 1.
Fig. 3 be shown in Fig. 1 the vertical view of lid.
In figure, 1, box body, 2, lid, 3, bolt slot, 4, support, 5, Type B conductive insert, 6, insert port, 7, insertion end, 8, wire draw-in groove, 9, body frame, 10, spacing top board, 11, trapezoidal stopper slot, 12, conducting strip.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
A kind of terminal box as shown in Figure 1, Figure 2 and Figure 3, it comprises box body 1, lid 2 and conducting strip 12, and box body 1 inside is provided with trapezoidal stopper slot 11, and the outside of trapezoidal stopper slot 11 is provided with insert port 6, and lid 2 is all provided with bolt slot 3 with box body 1; Conducting strip 12 comprises body frame 9 and support 4, and the end of body frame 9 is provided with wire draw-in groove 8, and support 4 is all provided with B shape conductive insert 5; The trapezoidal gradient of trapezoidal stopper slot 11 is at 45 °-60 °; Support 4 is provided with 4, and the angle of inclination of support 4 is 15 °-30 °; Insert port 6 is rectangle, and is 4-7cm apart from the distance of B shape conductive insert 5, and the insertion end 7 of insert port 6 is made as matrix; On lid 2, be all provided with spacing top board 10, and each spacing top board 10 is corresponding one by one with each trapezoidal stopper slot 11.
During work, spacing top board 10 cooperates mutually with trapezoidal stopper slot 11, and conducting strip 12 is stuck in trapezoidal stopper slot 11, and box body 1 fixes by bolt with lid 2, forms the terminal box of sealing, and plug inserts by insert port 6, is in contact with one another with Type B conductive insert 5.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technology people of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
