Abstract
The utility model discloses an assembled two-purpose anti-explosion junction box, which comprises an upper shell and a lower shell. The upper and lower shells are movably connected. A wiring board for connecting a line is arranged in a cavity formed by the upper and lower shells. Grooves I for sealing the cavity formed by the upper and lower shells are formed at joints of the end parts of the upper and lower shells. Grooves II for alleviating the tensile force of the line are also formed at the joints of the end parts of the upper and lower shells, and are formed outside the grooves I. The assembled two-purpose anti-explosion junction box has a simple and compact structure; the wiring board is arranged in the shell, so that the line is convenient to connect; and due to the adoption of the structures of the upper and lower shells, the assembled two-purpose anti-explosion junction box is easy to assemble, convenient to maintain, long in service life, high in safety performance and wide in application range.
Description
Technical field
The utility model relates to a kind of packaging 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 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.
The utility model content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of long service life, the packaging two logical anti-explosion terminal boxs that security performance is high.
The technical scheme of the utility model 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 utility model 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 utility model 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.
