Preferably, the lower end of the shell is provided with a groove, the cross section of the groove is U-shaped, and the sealing ring is embedded in the U-shaped groove.

Preferably, the bottom plate comprises a base plate, side plates and a supporting plate, wherein the side plates are arranged on two sides of the base plate respectively, the supporting plate is arranged between the base plate and the side plates, and the supporting plate, the base plate and the side plates are integrally formed.

Preferably, the base plate is provided with a reinforcing rib, and the base plate and the reinforcing rib are integrally formed.

The utility model has the beneficial technical effects that: the utility model discloses set contact pin and plastic housing and joint to a whole, reduced assembly process, and stopped the leakproofness problem between joint and casing, the quality is safe and reliable more, and the plastic housing quality is light, greatly reduced the weight of P shelves controller. The cavity is formed in the shell, the mounting space of internal electrical components is enlarged, and the two reinforcing ribs are punched on the weak part of the bottom plate, so that the strength of the bottom plate can be improved, the thickness of the bottom plate is reduced, and the heat dissipation of the internal components is facilitated. In addition, the lower end of the shell is provided with a U-shaped groove for installing a sealing gasket, so that the shell and the bottom plate can be sealed without dead angles, and water and dust are effectively prevented from entering the shell. The whole base plate is designed in an arch shape, and water accumulation of the shell and the base plate can be effectively avoided. The circuit board is suspended in the shell, is favorable for fully contacting with the internal air and is favorable for heat dissipation of the circuit board.

Detailed Description

The invention is further described below with reference to the following examples and figures:

example one

As shown in fig. 1, 2 and 3, the P-gear controller includes a housing 1, a connector 2, a pin 3, a circuit board 5 and a bottom plate, wherein cavities are formed in the housing 1 and the connector 2, the connector 2 is integrally connected to one end of the housing 1, and an opening is formed in the other end of the connector 2. An inner convex plate 13 is integrally formed on the inner side of the shell 1, and the plurality of contact pins 3 penetrate through the inner convex plate 13 after penetrating through the connector 2, so that one ends of the contact pins 3 are fixed in the shell 1, and the other ends of the contact pins 3 are fixed in the inner convex plate 13. With one end of the plurality of pins 3 in the cavity of the header 2 and the other end of the pins 3 in the cavity of the housing 1, a circuit board 5 is mounted in the cavity of the housing 1 with screws through the circuit board 5 so that the lower ends of the pins 3 contact the circuit board 5.

In order to prevent dust, water vapor and the like from entering the cavity of the shell 1 and causing adverse effects on the circuit board 5, the lower end of the shell 1 is provided with a groove 12, the cross section of the groove 12 is U-shaped, and a sealing ring 4 is arranged in the U-shaped groove 12. The bottom plate is arranged below the shell 1, a screw penetrates through the bottom plate, and when the bottom plate is arranged on the shell 1, the shell 1 and the bottom plate can press the sealing ring 4 arranged in the U-shaped groove 12 together.

The bottom plate comprises a base plate 61, side plates 62 and a supporting plate 63, wherein the two sides of the base plate 61 are respectively provided with one side plate 62, the supporting plate 63 is vertically arranged between the base plate 61 and the side plates 62, and the supporting plate 63, the base plate 61 and the side plates 62 are integrally formed. Therefore, the base plate 61 can be higher than the side plate 62 by a distance, the bottom plate forms a bow-shaped structure on the whole, and water accumulation at the bottom of the P-gear controller can be effectively avoided. The bottom plate pressing sealing ring 4 means that: the seal ring 4 is pressed by the base plate 61. In order to enhance the strength of the bottom of the P-range controller, the base plate 61 is provided with a reinforcing rib 64, the reinforcing rib 64 can be strip-shaped, corrugated or annular, and the base plate 61 and the reinforcing rib 64 are integrally formed.

It will be apparent that modifications and variations are possible without departing from the principles of the invention.
