Abstract

The utility model relates to a control box with a circuit board mounted therein. The control box comprises an upper casing, a lower casing, and the circuit board, wherein the upper and the lower casings are buckled together; and the circuit board is mounted in the control box. The control box is characterized in that the upper and the lower casings are tightly buckled together through a convex edge opening and a concave groove opening which are matched; the vertically extending height of the outside groove wall of the concave groove opening is larger than that of the inside groove wall; and the inner and the outer ledges of the convex edge opening and the inside and the outside groove walls of the concave groove opening are matched with each other in height and the inner components are higher than the outer component. Compared with the prior art, the utility model can well realize tight connection and buckling of the upper and the lower casings, thereby causing better sealing effect.

Description

A kind of control box

Technical field

The utility model relates to the control box that circuit board is housed in a kind of.

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.

Summary of the invention

The purpose of this utility model provides at existing weak point in the above-mentioned prior art just that a kind of structure is more reasonable, sealing property control box preferably.

The purpose of this utility model can realize by following technique measures:

Control box of the present utility model comprises upper shell and the lower house that snaps together mutually, and is arranged on the circuit board in the control box, and described upper and lower casing closely snaps together by convex edge mouth and the concave notches that cooperatively interacts; And the vertical extended height of the outside cell wall of described concave notches is greater than the vertical extended height of inboard cell wall, and the height of the height of the inside and outside shoulder of described convex edge mouth and the medial and lateral cell wall of described concave notches is the interior height that cooperatively interacts, outer low version; This structure can make the sealing effectiveness between upper shell and the lower house be further enhanced.

The utility model also is provided with the thread connection hole that is used for the spinning attachment screw that cooperatively interacts at four jiaos of places of described upper shell and lower house, so as to make between upper shell and the lower house be connected more solid and reliable.

The described lower house of the utility model is provided with at least one data terminal and plugs mouth.

The beneficial effects of the utility model are as follows:

The utility model can better be realized the tight fastening that connects between the upper and lower casing making sealing effectiveness better compared to existing technology.

Embodiment

The utility model is described in further detail below with reference to embodiment (accompanying drawing).

As shown in Figure 1 to Figure 3, control box of the present utility model comprises upper shell 11 and the lower house 12 that snaps together mutually, and is arranged on the circuit board 2 in the control box 1; Described upper and lower casing closely snaps together by convex edge mouth 111 and the concave notches 121 that cooperatively interacts; And the vertical extended height of the outside cell wall 122 of described concave notches 121 is greater than the vertical extended height of inboard cell wall, and the height of the height of the inside and outside shoulder of described convex edge mouth 111 and the medial and lateral cell wall of described concave notches 121 is the interior height that cooperatively interacts, outer low version (referring to shown in Figure 4); This structure can make the sealing effectiveness between upper shell and the lower house be further enhanced.

The utility model also is provided with the thread connection hole that is used for the spinning attachment screw (accompanying drawing does not show) that cooperatively interacts at four jiaos of places of described upper shell and lower house, so as to make between upper shell and the lower house be connected more solid and reliable.

The described lower house of the utility model is provided with at least one data terminal and plugs mouth 123.

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 edge mouth 111 with upper shell 11 inserts in the concave notches 121 of corresponding lower house 12 again, simultaneously, outside cell wall 122 extensions of lower house 12 stretch to the convex edge mouth 111 outer shoulders (Access Division 112) of upper shell 11 and locate, 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.

In the present embodiment, also offer two data terminals on the lower house 12 and plug mouth 123, this data terminal plugs mouth 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.

Claims
