Abstract
The utility model relates to an explosion-proof terminal box, which is formed by a terminal box cover and a terminal box body, wherein a sealing structure is arranged on the matching surface of the terminal box cover and the terminal box body, a groove is formed on a flange surface on one side of the terminal box cover, and a sealing ring is relatively arranged in the groove, a sealing convex rib is formed on one side of the terminal box body corresponding to the groove, the sealing surface of the sealing convex rib is adjacently arranged with the sealing ring to form the sealing structure, the outer wall on one side of the flange surface of the terminal box cover is extended towards the direction of the terminal box body to form a protective wall, the height of the protective wall is larger than the depth of the groove in the terminal box cover, a step which is matched with the protective wall is formed on the outer edges of the sealing convex rib on the terminal box body, the step plane is lower than the sealing surface of the sealing convex rib, and the step is engaged with the protective wall of the terminal box cover to form a protective wall type protective structure. The utility model is further provided with a protective wall type protective structure, and makes the explosion-proof terminal box directly resist the impacts of water or dust to matching separation surface of the terminal box cover and the terminal box body, and further increases the sealing effect of the explosion-proof terminal box.
Description
Technical field
The utility model relates to a kind of anti-explosion terminal box.
Background technology
Existing anti-explosion terminal box is made up of parts such as terminal box bodies, wherein the terminal box body is the two halves split-type structural, connector cover and junction box body by upper and lower cooperation are formed, on both mating surfaces, be provided with hermetically-sealed construction, form groove at the flange face upper edge of connector cover one side flange face, be provided with sealing ring in groove, respective slot one side forms seal bead on junction box body, and the sealing surface close neighbour of the end face of seal bead and sealing ring is provided with the formation hermetically-sealed construction.Existing anti-explosion terminal box adopt seal bead with the hermetically-sealed construction of sealing ring, though possess certain sealing effectiveness, but seal bead and the position of groove all are to be set directly at the cooperating on the division surface of connector cover and junction box body, impact under the situation that cooperates division surface when running into outside water or dust, its sealing effectiveness is not very desirable just.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, provides a kind of sealing property better anti-explosion terminal box.
For achieving the above object; the utility model adopts a kind of anti-explosion terminal box; comprise the terminal box body; the terminal box body is the two halves split-type structural; form by connector cover and junction box body; on both mating surfaces, be provided with hermetically-sealed construction; on the flange face of connector cover one side, form groove; the corresponding sealing ring that is provided with in groove; respective slot one side forms seal bead on junction box body; the sealing surface of seal bead and sealing ring close neighbour are provided with the formation hermetically-sealed construction; the outer wall of flange face place one side of connector cover extends to form the protection wall towards the junction box body direction, and protection wall height is greater than the degree of depth of connector cover inner groovy, and the seal bead outer edge on the junction box body forms and the suitable step of protection wall; the step plane is lower than the sealing surface of seal bead, and step cooperates formation revetment formula safeguard structure with the protection wall of connector cover.
The utility model further is set to the outer edge of the protection wall formation groove of connector cover.
The utility model is on the basis of existing hermetically-sealed construction, set up one deck revetment formula safeguard structure again, make anti-explosion terminal box can resist the direct impact of the cooperation division surface of water or dust butted line lid and junction box body, further improve the sealing effectiveness of anti-explosion terminal box.
