Description
Technical field
The utility model relates to device sealing field, particularly relates to a kind of controller box.
Background technology
Controller is as the core of automation/semi-automatic product, and its importance is self-evident.Because product relates to various different field, controller is also faced with different environments for use.When running into hot and humid environment, the sealing of device seems particularly important to the useful life of controller or even the personal safety of user.The sealing means of traditional controller box control circuit is loaded a cavity, and the connection of control circuit and external power source generally adopts direct cabling of boring a hole on cavity wall to realize, and then uses sealing plug to seal through wires hole.This sealing means can only reach three grades of sealings, i.e. hydraulic seal degree, undesirable to the obturation effect of gas, and the quality of sealing plug directly has influence on the integral sealing effect of seal box.
Utility model content
The technical problems to be solved in the utility model is, provides one not use sealing plug just can reach secondary seal, namely reaches the controller box of rate of pressurization.
For achieving the above object, the utility model adopts following scheme: comprise housing and bonnet, described housing lower frame is provided with the first through hole, the cavity installing control circuit is provided with in housing, on the cavity wall of cavity along, be provided with annular groove around cavity wall, bonnet is provided with the projection for seal chamber with fit depressions; A seal groove be connected with the integral type of cavity is provided with in cavity, the side that seal groove is connected with cavity is provided with the first through wires hole be communicated with containment portion, the other side of the seal groove adjacent with described first through wires hole is provided with the second through wires hole be communicated with inside cavity, the data wire of control circuit and power line pass from the first through wires hole through the second through wires hole and seal groove successively, are provided with the filler for intercepting water, gas in seal groove.
As preferably, the cross section of projection set on bonnet is rectangle.After housing and bonnet fasten, projection on bonnet snaps in the groove in the middle part of cavity hatch end, the filler for intercepting water, gas is filled with between projection and groove, because projection coordinates completely with groove, filler is stressed close with other positions in bottom portion of groove both sides corner, avoid cambered surface projection can not coordinate completely with groove, bottom seal groove, two corners are stressed less, make filler unbalance stress cause the imperfect problem of sealing effectiveness.
As preferably, protruding height is greater than the degree of depth of groove.
As preferably, position adjacent with the first through hole on bonnet is provided with detachable member, and detachable member is provided with the second through hole.Due to the restriction of mounting condition, sometimes need the extraction location adjusting data wire and power line, or draw from housing side or directly draw from bonnet.Because bonnet adopts fabricated structure, the adjustment of extraction location can be completed under the prerequisite not exclusively dismantling bonnet, avoid the destruction to controller box first achieve.
The beneficial effects of the utility model are:
The first through wires hole that the data wire of control circuit board and power line are provided with through seal groove and the second through wires hole form " L " type structure, increase seal distance, the filler that can intercept aqueous vapor is filled in seal groove, water droplet or steam can be stopped completely and infiltrate the cavity being provided with control circuit, avoid the impact of sealing plug product confrontation sealing effectiveness, and easy to operate.

Embodiment
Below in conjunction with exemplary embodiment, execution mode of the present utility model is described:
The utility model provides a kind of controller box, as shown in Figure 1, comprises housing 1 and bonnet 2, housing 1 lower frame is provided with the first through hole 3, position adjacent with the first through hole 3 on bonnet 2 is provided with detachable member 8, and detachable member is provided with the second through hole 9, as shown in Figure 3.What Fig. 2 showed is the internal structure of housing 1, the cavity 4 installing control circuit is provided with in housing 1, edge on the cavity wall of cavity 4, annular groove 6 is provided with around cavity wall, bonnet 2 is provided with the projection 7 for sealing cavity 4 with fit depressions, a seal groove 5 be connected with the side integral type of cavity 4 is provided with in cavity 4, the side that seal groove 5 is connected with cavity 4 is provided with the first through wires hole 5.1 with cavity 4 ft connection, the other side of the seal groove 5 adjacent with described first through wires hole 5.1 is provided with the second through wires hole be communicated with cavity 4 inside, the data wire of control circuit and power line pass from the first through wires hole 5.1 through the second through wires hole 5.2 and seal groove 5 successively, the filler that can intercept aqueous vapor is filled with in seal groove 5.The cross section of projection 7 set on bonnet 2 is rectangle, as shown in Figure 4.
Another internal structure of the housing 1 that Fig. 5 shows.According to this internal structure, then also to do corresponding adjustment to the shape of the projection 7 that groove 6 matches on bonnet 2.
The part do not set forth in specification is prior art or common practise.The present embodiment only for illustration of this utility model, and is not used in restriction scope of the present utility model, and the amendment such as the equivalent replacement that those skilled in the art make for the utility model is all thought to fall in this utility model right claim institute protection range.
