Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

The utility model provides a kind of terminal box, which includes shell 1 and terminal plate 2, and shell 1 is open at one end, The shell 1 can be positive cube shape, and shell 1 is arranged in wall, and the end face of open end is concordant with metope, inside shell 1 Trailing flank on setting two terminal plates 2 parallel with trailing flank, terminal plate 2 can be by the terminal plate that is arranged on terminal plate 2 Connecting hole 10 is bolted, and three wiring piles 3 can be set on each terminal plate 2, and wiring pile 3 can be cuboid Shape can connect by bolted connection on terminal plate 2, be respectively provided on each wiring pile 3 there are three for The termination of the electric wire connection of terminal box is penetrated from wall, three terminations on each wiring pile 3 are electrically connected mutually, and one A termination connects electric wire, and other two termination is powered, 3 one connection firewires of above three wiring pile, a company Ground line, a connection zero curve, every line occupy a termination on corresponding wiring pile 3, remaining termination is used for and opens Box connection is closed, perhaps for the series connection of route between switch enclosure or plays the role of route transfer, so greatly reduces out The wiring pressure for closing box, when the route that terminal box needs to connect is more, the prior art can only be carried out by the interface on switch enclosure Connection, often an interface needs to connect several threads, can also place a plurality of route in terminal box, and switch enclosure is caused to be difficult to be put into and connect The problem of wire box, the utility model play connection switch box and line so set, terminal plate 2 undertakes the main pressure of wiring The effect of road series connection or transfer, several threads road needed for switch enclosure only needs connection switch box itself.

When the switch enclosure and terminal box of the prior art are fastenedly connected, need the fastening bolt holes and terminal box on switch enclosure On fastening bolt holes alignment after be screwed into fastening bolt, in most cases, switch enclosure and terminal box when installing fastening bolt 62 On fastening bolt there is no being aligned, installation is inserted into fastening bolt, time-consuming and laborious, the utility model thus by the feeling of worker entirely The fastening bolt holes 4 with guide function are increased on existing switch box base, the front end of fastening bolt holes 4 is i.e. close to shell 1 Open end one end is carry section 41, and 41 rear end of carry section is fastening section 42, and carry section 41 has guide function, and 41 inner wall of carry section is Arc is big end close to 1 open end of shell, is small end close to 42 one end of fastening section, and small end is hexagonal structure, small end and fastening Section 42 is connected to, and fastening section 42 is also hexagonal structure, and inside is placed with fastening nut, and being set as hexagonal structure is in order to prevent Fastening nut rotation, by carry section 41 be set as pre-large post-small structure be in order to fastening bolt 62 pass through switch enclosure after can To quickly enter in fastening bolt holes 4, carry section 41 is arc, and 41 inner wall of carry section plays guiding role, and fastening bolt 62 is suitable 41 inner wall of carry section enter fastening section 42 and link together with fastening nut, eliminate the step of manually looking for hole.

, with ground level, it can pacify in the inside bottom surface of terminal box to make terminal box when installing terminal box as far as possible An air level 5 is filled, which is mounted on the front side center of bottom surface, which is circle bubble, works as wiring When box level, the bubble in air level 5 is located at 5 center of air level.

Above-mentioned termination includes the bolt hole 61 being arranged on wiring pile 3 and wiring hole 63 and is arranged in bolt hole 61 Interior bolt 62, is evenly provided with three bolts hole 61 on the face perpendicular to the ground of wiring pile 3, and bolt hole 61 and the face are hung down Straight setting, is provided with one with each 61 corresponding position of bolt hole on the face of 1 center side of shell in each wiring pile 3 Wiring hole 63, wiring hole 63 are connected to bolt hole 61, and the section of wiring hole 63 can be rectangle, and 61 rear end of bolt hole is i.e. far from outer 1 open end side of shell is concordant with the rear end of wiring hole 63, is provided with bolt 62 in each bolt hole 61, and when wiring inserts the end of a thread Enter in wiring hole 63, tightens bolt 62, the end of a thread is pressed in 61 rear end face of bolt hole by bolt 62 is connected to the end of a thread with wiring pile 3.

It is located at 62 side of bolt to prevent from tightening the end of a thread after bolt 62 and is not crushed on bolt 62 and 61 rear end face of bolt hole Between cause false the phenomenon that connecting, length of the wiring hole 63 along the vertical direction in 61 central axes of bolt hole can be less than bolt hole 61 Diameter, such setting can guarantee that the end of a thread is always positioned between 61 rear end face of bolt 62 and bolt hole.

In order to make fastening bolt 62 enter fastening bolt holes 4 at the first time after switch enclosure, above-mentioned fastening bolt holes 4 Front end is concordant with the end face of 1 open end of shell to be arranged.

In order to make three terminations on each wiring pile 3 be electrically connected mutually, the material of wiring pile 3 can be set to Conductive material, such as iron, copper etc., to prevent from connecting between wiring pile 3 electricity, terminal plate 2 can be set to insulating materials, such as fire-retardant Plastics etc..

To prevent two terminal plates 2 from blocking the incoming line on 1 rear end face of shell, every piece of terminal plate 2 can be set to Concave, when installation, the notch of concave terminal plate 2 is opposite to be installed, and the hole edge that two notches are formed is located at inlet wire On the outside of 7 edge of hole.

It, can be in terminal box for the connection between terminal box when a position needs to install multiple terminal boxes on wall Be arranged on the lateral wall of front end face it is multiple can be with mutually matched plug 8 and slot 9.

Further, two above-mentioned plugs 8 are respectively provided on shell 1 open end arbitrary neighborhood, two lateral walls, remaining two While being respectively provided with two slots 9, above-mentioned slot 9 is cylindrical hole, is arranged along 1 front-rear direction of shell, and above-mentioned plug 8 is cylindrical body knot Structure, when two terminal boxes need to be fixedly connected, plug 8, which is inserted into slot 9, to be fixedly connected.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power Benefit.
