Its characteristics have the circumference groove on the oral area terminal surface of box body, and the circumference inslot has the heating wire that link up its circumference overall length. There is a downward protruding muscle of week in the downside border department of lid, week downward protruding muscle shape, size and circumference groove looks adaptation, week downward protruding muscle embedding circumference groove, and the downside that makes downward protruding muscle of week with the heating wire contacts. Box body and lid are plastic products, through linking together being sealing saddle between lid and box body oral area to the heating wire power heating. This kind of controller shell, it is sealed effectual. Adopt this kind of shell, can avoid ensureing the car booster and can normally working in the rainwater gets into the shell. Be particularly useful for on the electron executor on the car booster.

Description

A kind of controller housing

Technical field

This utility model relates to a kind of electric appliance casing.Specifically, it is used to accommodate the sealing shape shell of circuit board, is particularly suited in the electronic actuators on automobile booster.

Background technology

Both know about in automobile booster manufacturing, after electronic actuators on automobile booster and controller thereof are installed on automobile, it is in naked state, working environment is poor, therefore, the airtight quality quality of controller housing, can not only determine automobile booster normally work, and also decides the service life of controller.If the body seal of controller is bad, once enter rainwater, will be burned so that automobile booster cannot work.At present, the controller housing supporting with the electronic actuators on automobile booster is all traditional product, and this controller housing contains housing and cap, and the connection between housing oral area and cap mainly connects with screw or fluid sealant connects.Employing screw connects, and sealing effectiveness is poor, and rainwater is easily accessible in shell so that controller easily burns out, automobile booster cannot normally work.Employing fluid sealant connects, and can improve the sealing effectiveness between housing oral area and cap, but owing to fluid sealant is different from the material of housing, the time one is long, easy degumming between housing and cap.Once degumming between housing and cap, rainwater still can enter in shell, still cannot ensure the normal work of automobile booster.

Utility model content

Problem to be solved in the utility model is to provide a kind of controller housing.This controller housing, good sealing effect.Use this shell, rainwater can be avoided to enter in shell, it is ensured that automobile booster can normally work.

The problems referred to above to be solved in the utility model are realized by techniques below scheme:

Controller housing of the present utility model includes that box body, box body oral area have lid.It is characterized on the oral area end face of box body having circumferential slot, in circumferential slot, has the heating wire of its circumference overall length through.There is week convex tendon downwards the edge, downside of described lid, and all shapes of convex tendon downwards, size are suitable with described circumferential slot, and described week, downward convex tendon embedded circumferential slot, and made the downside of week convex tendon downwards contact with described heating wire.Described box body and lid are plastic, by between lid and box body oral area can linking together heating wire electrified regulation in sealing shape.

Further improvement of the utility model scheme is, the opposite sides of described circumferential slot all has outer salient point so that lid after docking with box body oral area the heating wire in outer salient point exposed outside, in order to as the contact connected with power supply.

Further improvement project of the present utility model is, described heating wire is docked in free shape by two segment unit heating wire and forms, and butt end therein the most outwards bends, and bending end is in the corresponding outer salient point of circumferential slot.

As can be seen from the above scheme, owing to being machined with circumferential slot on the oral area end face of box body, in circumferential slot, there is the heating wire of its circumference overall length through.The edge, downside of described lid is machined with week convex tendon downwards, and described week, downward convex tendon embedded circumferential slot, and made the downside of week convex tendon downwards contact with described heating wire.And described box body and lid are plastic, by between lid and box body oral area can linking together heating wire electrified regulation in molten so that link together in gapless shape between housing oral area, heating wire and lid three.Achieve between box body with lid permanent docks, substantially increase sealing effectiveness, it is to avoid the situation that rainwater enters occurs, it is ensured that automobile booster can normally work.

Detailed description of the invention

As shown in Figure 1,2,3, 4, controller housing of the present utility model includes box body 4 and lid 2, and the oral area end face of box body 4 is machined with circumferential slot, is placed with the heating wire 3 of its circumference overall length through in circumferential slot.The edge, downside of described lid 2 is machined with week convex tendon 1 downwards, week the shape of convex tendon 1 downwards, size suitable with described circumferential slot, described week, downward convex tendon 1 embedded in circumferential slot, and made the downside of week downward convex tendon 1 contact with described heating wire 3.Described box body 4 and lid 2 are plastic, by between lid 2 and box body 4 oral area can linking together heating wire 3 electrified regulation in sealing shape.

For ease of to heating wire 3 electrified regulation, the opposite sides of described circumferential slot is all machined with outer salient point 5 so that lid 2 after docking with box body 4 oral area the heating wire 3 in outer salient point 5 exposed outside, in order to as the contact connected with power supply.

For ease of processing, described heating wire 3 is docked in free shape by two segment unit heating wire and forms, unit heating wire therein is approximation U-shaped, the butt end of two unit heating wire is all machined with bent outward trisection 6, bent outward trisection 6 with one end is parallel and is in the corresponding outer salient point 5 of circumferential slot, two bent outward trisections 6 of same one end form an electrode contacts.

Add man-hour, first two unit heating wire are put into the circumferential slot of box body 4 oral area, and in making the corresponding outer salient point 5 of outside cell wall of circumferential slot that they are on box body 4 with the bent outward trisection 6 of one end.Close lid 2 again, makes the week downward convex tendon 1 at edge, lid 2 downside embed in the circumferential slot of box body 4 oral area.Then, the two poles of the earth making power supply contact with the contact in two outer salient points 5 respectively, heating wire 3 is carried out electrified regulation, make to link together in molten between lid 2 and box body 4 oral area, make to link together in gapless shape between box body 4 oral area, heating wire 3 and lid 2 three, it is achieved thereby that permanent between box body 4 with lid 2 docks.
