Abstract
A two-way explosion-proof junction box comprises an upper shell and a lower shell. The upper shell is flexibly connected with the lower shell. A wiring board, which is used to connect a line, is arranged in a cavity formed by the upper shell and the lower shell. A groove I, which is used to seal the cavity formed by the upper shell and the lower shell, is arranged on a combination part of ends of the upper shell and the lower shell. A groove II, which is use to ease a line pulling force, is also arranged on the combination part of the ends of the upper shell and the lower shell. The groove II is arranged on an outer side of the groove I. According to the invention, a structure is simple and compact. The wiring board is installed in the shell so that line connection is convenient. Through the structure of the upper shell and the lower shell, assembling is easy, maintenance is convenient, a service life is long, safety performance is high and a suitable scope is wide.
Description
Technical field
The present invention relates to a kind of two logical anti-explosion terminal boxs.
Background technology
Existing two logical anti-explosion terminal boxs are mainly two kinds: first kind for installing wire protecting template in explosion-resistant enclosure; Be positioned over the circuit that connects on the template then, its sealing is mainly accomplished by the cushion rubber that is enclosed within on the circuit, and this type of two logical explosion-proof wiring pipe set inside is complicated; Installing and replacing inconvenience; And cushion rubber only receives axial compression, and certain distortion, poor sealing can take place extruded cushion rubber.Another kind of this type of common terminal box sealing is also mostly to be to apply axial force through bolt to cushion rubber to seal in order in hollow shell, to establish terminal block, and its sealing property is relatively poor.
Chinese patent ZL 200620024061.2 discloses a kind of two-way explosion-proof terminal box, and it comprises explosion-proof casing, lid, and explosion-proof casing is the unimpeded hollow cylinders in two ends, wire protecting template in the explosion-proof casing; In the wire protecting template and be positioned at same horizontal plane and be provided with an axial threading hole at least; Have groove on the wire protecting template outer surface; On the explosion-proof casing and corresponding to the position of the screw in the middle part of the wire barrel interior earth stud is housed, the wire protecting template two ends have interior grounding through hole; Be fixed with the external ground screw rod on the explosion-proof casing.It all is encapsulated in associated tracks in the wire protecting template that can separate with explosion-proof casing and can arbitrarily dismantle, and when going wrong, maintenance is trouble, wastes time and energy inefficiency.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the present invention provides a kind of long service life, the two logical anti-explosion terminal boxs that security performance is high.
Technical scheme of the present invention is: it comprises upper shell and lower house; Upper shell and lower house flexibly connect; Be provided with the terminal block that is used for connection line in the inner chamber that constitutes by upper shell and lower house; Upper shell and junction, lower house end are provided with the groove I that is used to seal the inner chamber that is made up of upper shell and lower house, and upper shell and junction, lower house end also are provided with the groove II that is used to alleviate the circuit pulling force, and the groove II is located at the groove I outside.
Further, said upper shell and lower house flexibly connect through bolt.
Further, be provided with the rubber hose that seals in the said groove I.
Further, said terminal block passes through bolted on lower house.
Further, said terminal block is provided with and tights a bolt to what circuit was fixed.
The present invention is simple in structure, compact, and the installation connection plate makes that the circuit connection is more convenient in the shell, the structure of last lower house; Feasible assembling is easier; Keep in repair more conveniently, the rubber hose as the groove I place of line outlet has realized the sealing to line outlet simply and easily; The pulling force of junction has been alleviated in the design of groove II, makes the circuit pulling force not act on the junction, and it is more reliable that circuit is connected, long service life, and security performance is high, and is applied widely.

Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
With reference to accompanying drawing; Present embodiment comprises upper shell 1 and lower house 3; Upper shell 1 is realized being connected through bolt I 2 with lower house 3; Be provided with the terminal block 4 that is used for connection line in the inner chamber that is made up of upper shell 1 and lower house 3, terminal block 4 is anchored on the lower house 3 through bolt II 5, and terminal block 4 is provided with tightens screw 8 to what circuit in the box was fixed; Upper shell 1 is provided with the groove I 6 that is used to seal the inner chamber that is made up of upper shell 1 and lower house 3 with junction, lower house 3 end; Be provided with rubber hose 9 in the groove 6 and be used for the sealing path outlet, upper shell 1 also is provided with the groove II 7 that is used to alleviate the circuit pulling force with junction, lower house 3 end, and groove II 7 is located at groove I 6 outsides.
Claims (5)
