Abstract

The utility model relates to an encapsulation of a controller, which comprises a box body and a circuit board that is arranged in the box body. The box body comprises an upper shell and a lower shell which is detachably connected with the upper shell, the periphery of the upper shell extends downwards and is provided with convex ribs, the periphery of the lower shell is provided with grooves, the positions of which correspond to that of the convex ribs on the upper shell, and the upper shell is buckled with the grooves on the lower shell by the convex ribs. By inserting the convex ribs on the upper shell into the corresponding grooves on the lower shell, the upper shell and the lower shell are connected more closely, and the sealing effect is better.

Description

A kind of encapsulation of controller

Technical field

The utility model relates to a kind of shell encapsulating structure of controller.

Background technology

As everyone knows, some electric control gears all need by box body its control circuit to be sealed in wherein, particularly be applied in outdoor controller for some, require control box to have better seal, thereby prevent that thereby rainwater or moisture from entering the useful life that box body influences controller, traditional control box comprises lower house, between the last lower house or a side is hinged that opposite side is sealed to form, be exactly to go up lower house to be formed by connecting by screw, owing to have the slit between upper shell and the lower house, so sealing effectiveness is often not ideal enough.

The utility model content

The utility model purpose just provides the encapsulation of controller preferably of a kind of sealing property.

In order to reach above-mentioned utility model purpose, the technical solution of the utility model is: a kind of encapsulation of controller, comprise box body, be arranged on the circuit board in the described box body, the lower house that described box body comprises upper shell, removably connects with upper shell, the periphery of described upper shell is extended with convex tendon downwards, the periphery of described lower house offers the corresponding groove in convex tendon position with upper shell, and described upper shell is interlocked by the groove on its convex tendon and the described lower house.

Further, described convex tendon and described upper shell outward flange form the Access Division at a distance of setpoint distance, described lower house outward flange extends upward the formation extension, when described convex tendon is positioned at described groove, extension on the described lower house embeds described Access Division and is fitted with the Access Division, be connected with the further of extension by the Access Division, make that the sealing effectiveness between upper shell and the lower house is further enhanced.

Also be connected between described upper shell and the lower house by screw, like this can be so that being connected between upper shell and the lower house is more solid.

Offer at least one data terminal on the described lower house and plug mouth.

Because the utilization of technique scheme the utlity model has following advantage: the utility model inserts in the lower house corresponding grooves by the convex tendon on the upper shell, thereby makes the more driving fit that is connected between upper shell and the lower house, and sealing effectiveness is better.

Wherein: 1, box body; 11, upper shell; 11, convex tendon; 112, Access Division; 12, lower house; 121, groove; 122, extension; 123, plug mouth; 2, circuit board;

Embodiment

Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:

The encapsulating structure of controller as shown in Figure 1 to Figure 3, comprise box body 1, be arranged on the circuit board 2 in the box body 1, box body 1 is made up of upper shell 11 and lower house 12, periphery at upper shell 11 is extended with convex tendon 111 downwards, the position that is complementary at the periphery and the convex tendon 111 of lower house 12 offers groove 121, simultaneously, the outward flange of the outside of convex tendon 111 and upper shell 12 is at a distance of certain distance, thereby convex tendon 111 is with respect to forming a vacancy Access Division 112 between upper shell 11 outward flanges, the outward flange of described lower house 12 extends upward and forms a protrusion and groove 12 extension 122 highly, when in use, as shown in Figure 4, circuit board 2 is arranged in the box body 1, in the present embodiment, circuit board 2 loads are located between the inboard of lower house 12, convex tendon 111 with upper shell 11 inserts in the groove 121 of corresponding lower house 12 again, simultaneously, the extension 122 of lower house 12 stretches in the Access Division 112 of upper shell 11, at this moment promptly, embed mutually each other respectively between upper shell 11 and the lower house 12 and connect, thereby guaranteed the sealing that connects.

For the further reliability that guarantees connection, also pass through the screw (not shown) between upper shell 11 and the lower house 12 at interval simultaneously with fixing.

In the present embodiment, also offer two and plug mouthfuls 123 on lower house 12, this plugs mouthfuls 123 and is used for drawing the data splicing ear to outside from circuit board 2, thereby carries out the transmission and the control of data.
