Abstract
A three-way anti-explosion terminal box comprises a shell, wherein the shell consists of an upper shell and a lower shell which are in movable connection, the shell is of a three-way structure, a wiring board for connecting a circuit is arranged in an inner cavity formed by the upper shell and the lower shell, a groove I for releasing tension of the circuit is arranged at the joint of the end parts of the upper shell and the lower shell, a groove II for sealing the inner cavity formed by the upper shell and the lower shell is also arranged at the joint of the end parts of the upper shell and the lower shell, and the groove I is arranged outside of the groove II. The three-way anti-explosion terminal box is simple and compact in structure, the terminal box consists of the upper shell and the lower shell, thus being convenient in placement, the outlet of the circuit is simply sealed, and the tension of the circuit can be effectively released due to the groove structure.
Description
Technical field
The present invention relates to a kind of three-way explosion-proof terminal box.
Background technology
Mostly existing three-way explosion-proof terminal box is integral type, and armored cassette damages the back and changes inconvenience, and hermetically-sealed construction is complicated, and when circuit received bigger external force, line joint was drawn back easily, and functional reliability is relatively poor.
Chinese patent 03271184.0 discloses a kind of three-way explosion-proof terminal box, and it comprises box body, and box body is a hollow threeway shape, and three ends have internal thread, and box body divides body structure for the two halves formula, is fixed together by screw.When an end placed associated tracks in the box body to receive external force to pull, fragile, useful life was shorter, and the scope of application is less.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the above-mentioned defective that prior art exists, and provides a kind of replacing convenient, simple in structure, the three-way explosion-proof terminal box that functional reliability is higher.
The technical solution adopted for the present invention to solve the technical problems is: a kind of three-way explosion-proof terminal box; Comprise housing, housing is made up of upper shell and lower house, and upper shell and lower house flexibly connect; Said housing is the three way type structure; It is characterized in that be provided with the terminal block that is used for connection line in the inner chamber that is made up of upper shell and lower house, upper shell and junction, lower house end are provided with the groove I that is used to alleviate the circuit pulling force; Upper shell and junction, lower house end also are provided with the groove II that is used to seal the inner chamber that is made up of upper shell and lower house, and the groove I is located at the groove II 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 II.
Further, said terminal block passes through bolted on the projection cylinder of lower house.
The present invention 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 alleviates the circuit pulling force effectively.

Fig. 1 is one embodiment of the invention cutaway view;
Fig. 2 is one embodiment of the invention front view;
Fig. 3 is a rubber hose structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
With reference to accompanying drawing; Present embodiment comprises housing; Housing is made up of upper shell 3 and lower house 5, and upper shell 3 flexibly connects through the bolt I with lower house 5, and said housing is the three way type structure; Be provided with the terminal block 6 that is used for connection line in the inner chamber that constitutes by upper shell 3 and lower house 5; Upper shell 3 is provided with the groove I 1 that is used to alleviate the circuit pulling force with junction, lower house 5 end, and upper casing 3 bodies and junction, lower house 5 end also are provided with the groove II 2 that is used to seal the inner chamber that is made up 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 said groove II 2.Said terminal block 6 is anchored on the projection cylinder of lower house 5 through bolt II 7.
In groove II 2, through laying rubber hose 8, be beneficial to sealing path outlet, it is fixing that the link tester that picks out through terminal block 6 is crossed groove I 1, is beneficial to alleviate the circuit pulling force.
