In order to overcome above-mentioned defective, the utility model provides a kind of terminal block housings, and this terminal block housings is simple in structure, installation, very easy to use, quick.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of terminal block housings; Comprise the square casing that upper side is opening-like; Be equipped with first wiring hole on the base plate of this square casing and the relative two side; Two relative inside sidewalls in addition at said square casing are arranged with along the sidewall direction at its place and the protuberance vertical with said base plate, and this protuberance extends on the base plate of said square casing; This in addition on the two relative outside faces and corresponding said protuberance lower end be provided with the central lines of this groove of groove and said protuberance; Offer the connection holes with the parallel sidewalls at its place at said protuberance center along vertical said base plate direction, be provided with screw thread in this connection holes, and the open upper end of this connection holes is in the upper side of said protuberance, lower ending opening is in said groove.
As the further improvement of the utility model, said protuberance and groove all are located at the sidewall center position at its place.
As the further improvement of the utility model, said square casing is a square.
As the further improvement of the utility model, on said in addition two relative sidewalls and be positioned at position, said groove both sides respectively symmetry be equipped with second wiring hole, and this second wiring hole extends on the said base plate.
As the further improvement of the utility model, on said two relative sidewalls and be positioned at the said first wiring hole downside respectively symmetry be equipped with the 3rd wiring hole, and the 3rd wiring hole extends on the said base plate.
As the further improvement of the utility model, said square casing also can be cuboid.
As the further improvement of the utility model, on said two relative sidewalls and be positioned at the said first wiring hole downside respectively symmetry be equipped with the 3rd wiring hole, and the 3rd wiring hole extends on the said base plate.
The beneficial effect of the utility model is: through on the relative sidewall of terminal box two, adding protuberance and groove and on this protuberance, forming a connection holes along sidewall direction; Be provided with screw thread in the connection holes, like this, need not liner during installation; The connection holes as long as screw is directly screwed, very easy to use.Simultaneously, can add wiring hole and extend to its base plate, like this, can be wired to from all quarter in the terminal block housings in this terminal box four sidewalls bottom, very easy to use.

Embodiment
In conjunction with accompanying drawing, the utility model is elaborated, but the protection range of the utility model is not limited to following embodiment.
Embodiment 1:
Like Fig. 1, shown in 2; A kind of terminal block housings; Comprise the opening-like square casing of upper side 1, this square casing is the square bodily form, on its base plate 2 and relative two side 3, is respectively equipped with first wiring hole 4; Be arranged with along the sidewall direction at its place and the protuberance 5 vertical with base plate 2 in the in addition two relative inside sidewalls of this square casing, this protuberance extends on the base plate of square casing; This in addition on the two relative outside faces and corresponding protuberance 5 lower ends be provided with groove 6, the central lines of this groove and protuberance; Offer the connection holes 7 with the parallel sidewalls at its place at the protuberance center along the vertical base plate direction, be provided with screw thread in this connection holes, and the open upper end of this connection holes is in the upper side of said protuberance, lower ending opening is in said groove.During use, only need to realize the installation of terminal block housings that very convenient can not caused the damage of terminal block housings simultaneously with this two connection holes of screw means.
Wherein, raised part and groove preferably all are located at the sidewall center position at its place.
In addition, on above-mentioned in addition two relative sidewalls and be positioned at position, groove both sides respectively symmetry be equipped with second wiring hole 8, and this second wiring hole extends on the base plate.On above-mentioned two relative sidewalls and be positioned at the said first wiring hole downside respectively symmetry be equipped with the 3rd wiring hole 9, and the 3rd wiring hole extends on the said base plate.Like this, but this terminal block housings can realize all inlet wires of four sidewalls and base plate, thereby wiring is more flexible, does not receive the restriction of wiring hole.
