Abstract
A multi-groove type three-way anti-explosion junction box comprises a shell consisting of an upper shell and a lower shell; the upper shell and the lower shell are movably connected; the shell is of a three-way type structure; a wiring board which is used for connecting circuits is arranged in a cavity consisting of the upper shell and the lower shell; a groove I used for relieving circuit tensile is arranged on a junction part between the ends of the upper shell and the lower shell; a groove II used for sealing the cavity consisting of the upper shell and the lower shell is also arranged on the junction part between the ends of the upper shell and the lower shell; and the groove I is arranged outside the groove II. The junction box is simple and compact in structure; the junction box is divided into the upper shell and the lower shell so as to be relatively convenient to change; circuit outlets are sealed easily; and the arranged groove structures can effectively relieve the circuit tensile.
Description
Technical field
The utility model relates to a kind of many groove types three-way explosion-proof junction box.
Background technology
Existing three-way explosion-proof junction box mostly is integral type, changes inconvenience after armored cassette damages, and hermetically-sealed construction is complicated, and when circuit was subject to larger external force, line joint was pulled open easily, and functional reliability is relatively poor.
Chinese patent 03271184.0 discloses a kind of three-way explosion-proof junction box, and it comprises box body, and box body is hollow threeway shape, and three ends have internal thread, and box body is two halves formula Split type structure, is fixed together by screw.When an end placed associated tracks in the box body to be subject to external force to pull, fragile, useful life was shorter, and the scope of application is less.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defects that prior art exists, and provides a kind of replacing convenient, simple in structure, the more much higher groove type three-way explosion-proof junction box of functional reliability.
The technical scheme that its technical problem that solves the utility model adopts is: many groove types three-way explosion-proof junction box, comprise housing, housing is comprised of upper shell and lower house, upper shell and lower house are flexibly connected, described housing is the three way type structure, it is characterized in that, be provided with the terminal block for connection line in the inner chamber that is consisted of by upper shell and lower house, upper shell and junction, lower house end are provided with for the groove I of alleviating the circuit pulling force, upper shell and junction, lower house end also are provided with for the groove II that seals the inner chamber that is made of upper shell and lower house, and the groove I is located at the groove II outside.
Further, described upper shell and lower house are flexibly connected by bolt.
Further, be provided with the rubber hose that seals in the described groove II.
Further, described terminal block by bolted on the projection cylinder of lower house.
The utility model is simple in structure, compact, and terminal box is divided into lower casing, changes more conveniently, and line outlet sealing is simple, groove structure is set can effectively alleviates the circuit pulling force.

Fig. 1 is the utility model one embodiment cutaway view;
Fig. 2 is the utility model one embodiment front view;
Fig. 3 is the utility model rubber hose structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises housing, housing is comprised of upper shell 3 and lower house 5, upper shell 3 and lower house 5 are flexibly connected by the bolt I, described housing is the three way type structure, be provided with the terminal block 6 for connection line in the inner chamber that is consisted of by upper shell 3 and lower house 5, upper shell 3 and junction, lower house 5 end are provided with for the groove I 1 of alleviating the circuit pulling force, upper casing 3 bodies and junction, lower house 5 end also are provided with for the groove II 2 that seals the inner chamber that is made of upper shell 3 and lower house 5, and groove I 1 is located at groove II 2 outsides.Be provided with the rubber hose 8 that seals in the described groove II 2.Described terminal block 6 is anchored on the projection cylinder of lower house 5 by bolt II 7.
By laying rubber hose 8, be beneficial to sealing path outlet in groove II 2, it is fixing that the link tester that picks out by terminal block 6 is crossed groove I 1, is beneficial to alleviate the circuit pulling force.
