Described O-ring seal both sides and offer the groove of locating on boss inside lower house fork pin below, O-ring seal both sides are respectively provided with one section of outside extension, for compressing special-shaped seal ring upper end.
On described upper shell, offer aperture, breather plug is installed in aperture.
Described controller housing adopts aluminum alloy materials to make.
In described O-ring seal and special-shaped seal ring, be added with metal ingredient.
The track of described special-shaped seal ring and lower house seal groove track are in full accord, but broadband is slightly wide and seal groove width, smooth-going whole spaces of intactly filling seal groove, and produce certain decrement.
The section ratio seal groove cross section of described special-shaped seal ring is bigger.
Buffer controller housing of the present utility model adopts the two-piece unit formula structure of band fork pin, formed by upper shell and lower house two parts, fork pin and prong coordinate for fixed cover PCB socket, on, special-shaped seal ring is installed between lower house and fork pin both sides, also comprise for being sleeved on O-ring seal in PCB socket, O-ring seal and special-shaped seal ring have formed continuous seal cavity, realize continuous tight seal, good water-proof effect, controller housing omnibearing protection the safety and stablization of circuit board, for the normal work of controller and retarder provides safety assurance, guarantee driving safety.
Further, on upper shell, offer aperture, breather plug is installed in aperture, in O-ring seal and special-shaped seal ring, be added with metal ingredient, realized ventilative and electromagnetic shielding protection simultaneously.
Further, controller housing aluminium alloy material, structural strength is high, can bear stronger vibratory impulse.

Fig. 2 is the structural representation of lower house in the utility model;
Fig. 3 is the structural representation of the PCB socket with O-ring seal in the utility model;
Fig. 4 is the structural representation of special-shaped seal ring in the utility model;
Fig. 5 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Be illustrated in figure 1 the upper shell of controller housing, on upper shell 1, offer with lower house 2 and pitch the prong 4 that pin 3 coordinates; Upper shell and lower house interface and prong inner side are all designed with seal boss, for compressing O-ring seal and special-shaped seal ring.
Be illustrated in figure 2 the lower house of controller housing, be provided with fork pin 3 on lower house 2, fork pin 3 coordinates with the prong 4 of upper shell for fixing circuit board socket.Seal groove is all designed in lower house and upper shell interface and fork pin both sides, and for location special-shaped seal ring 5 and O-ring seal 6 are installed, special-shaped seal ring and O-ring seal width are slightly wider than seal groove width.Fork pin inner side is provided with boss, for plate O-ring seal 6.
Be illustrated in figure 3 the PCB socket 9 that installs O-ring seal, O-ring seal 6 both sides and offer groove below, for locating on the boss in lower house fork pin inner side.There is one section of development length O-ring seal both sides, for compressing special-shaped seal ring upper end.
Be illustrated in figure 4 special-shaped seal ring, the track of special-shaped seal ring and lower house seal groove track are in full accord, but broadband is slightly wide and seal groove width, can smooth-goingly intactly fill whole spaces of seal groove, and produce certain decrement.
The horizontal component of the special-shaped seal ring shown in Fig. 4 is pressed in the seal groove of the controller housing lower cover shown in Fig. 2.Special-shaped seal ring and seal groove track are in full accord, and the section ratio seal groove cross section of special-shaped seal ring is bigger, and therefore sealing ring can smoothly be filled the whole spaces of full seal groove, and can produce certain decrement.
Cover shown in Fig. 3 is had to the controller lower house fork pin inner side shown in the PCB socket load map 2 of O-ring seal, fork pin both sides closely compress with O-ring seal draw-in groove, O-ring seal both side ends and special-shaped seal ring both side ends compression.
The alignment pin of controller housing upper cover shown in Fig. 1 and the location hole of lower cover are alignd, install the trip bolt of four positions, now the seal boss of upper cover compresses special-shaped seal ring just, and O-ring seal, forms sealing.
To sum up, complete the Seal Design of controller housing, the overall structure of controller housing as shown in Figure 5.
When controller long-term work, temperature can significantly raise, and can cause air pressure inside to increase.For avoiding electronic component operating characteristic in the time that pressure raises to change, on upper shell, design an aperture 7, breather plug 8 is installed in aperture 7, air pressure inside is communicated with atmospheric pressure.Breather plug permeable watertight can ensure not temperature influence of air pressure inside under the prerequisite of waterproof.
Due to the sensitiveness of electronic component, the electromagnetic wave of space outerpace can exert an influence to its operating characteristic.Therefore, in sealing ring material, add metal ingredient, make sealing ring and upper-lower casing form the conduction space of sealing, prevent the interference of electromagnetic radiation.
