Background

The PCB is a carrier for electrical connection of electronic components and has dual functions of a conductive circuit and an insulating bottom plate. Electronic components with various functions are generally soldered on a single side or on both sides of a PCB board, and circuit printing on the PCB board is designed according to the circuit function to be realized. Usually, the whole PCB is installed in a protective shell, so that the danger of electric shock is avoided, and the working interference of components on the circuit board is also avoided in order to isolate the external environment. Among the components and parts on the monoblock PCB board, the components and parts in some functional circuits are expensive, some components and parts are easy to damage, once some components and parts break down, the whole circuit can not work normally, sometimes, the damaged components and parts are difficult to replace singly, the monoblock PCB board can only be replaced, and great cost waste is caused. In view of the above, some circuit designers design a part of functional circuits in the whole circuit on another PCB board separately, and the two PCB boards are electrically connected by plugging. The design can reduce the occupied area of the original PCB, is favorable for miniaturization of a circuit, and only the corresponding PCB needs to be replaced when the components on the PCB are damaged, so that the manufacturing cost can be greatly saved.

The utility model discloses the circuit board protective housing studied uses in exactly the circuit design to the aforesaid is to inserting the structure, will change usually and the higher functional circuit of maintenance rate designs alone on a PCB board, pulls out the operation of inserting when for convenient maintenance and change, need set up a protective housing in this PCB board outside, this protective housing except forming the guard action to the PCB board, also protects maintenance personal's safety under the circumstances of circular telegram, the present case produces from this.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a circuit board protective housing, in the embedded protective housing of circuit board, this protective housing is convenient to pull out the operation of inserting the circuit board under the circular telegram condition.

In order to realize the above purpose, the utility model discloses the technical scheme who adopts is:

the utility model provides a circuit board protective housing, includes insulating housing, and the casing is one side open-ended box body structure, is equipped with the bead of joint circuit board on the shells inner wall, has seted up the louvre on the casing, and the symmetry sets up the buckle on one of them a set of opposite face of casing.

Furthermore, the middle part of the side wall where the buckle is located is a strip-shaped pressing part, the buckle is arranged at the edge of the pressing part, and notches are formed on two sides of the pressing part.

Furthermore, the pressing part and the position adjacent to the notch are recessed towards the inside of the shell to form a U-shaped through groove.

Furthermore, the bead includes vertical bead and horizontal bead, and horizontal bead sets up on pressing the splenium inner wall.

Furthermore, the radiating holes are symmetrically arranged on a group of side walls where the buckles are located, and the radiating holes are only distributed at one end of the side walls.

The utility model discloses a circuit board protective housing mainly designs to the circuit board in order to pegging graft mounting means interconnect, can imbed this protective housing internal fixation with a circuit board that maintenance frequency is higher, the protective housing passes through the buckle to be fixed in the bayonet socket department on another circuit board, even under the circumstances of circular telegram, the circuit board that also can hand the protective housing will need the maintenance is extracted and is changed, the protective housing forms safety protection except that the circuit board to the embedding, also for the maintenance change provides convenience, the operational safety has also been ensured.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The present embodiment discloses a circuit board protection shell, as shown in fig. 1 and 2, the protection shell is made of plastic material and is an insulating shell, and the whole shell is a rectangular box structure with an opening on one side. The inside circuit board that is used for holding the protection of casing, the circuit board need be fixed inside the casing, and this protective housing adopts the buckle mode to fix on another circuit board, realizes the plug-in electricity between two circuit boards and connects. Therefore, a structure capable of clamping the circuit board needs to be arranged on the inner wall of the housing, and the strip-shaped protruding rib protruding out of the inner wall of the housing is adopted as the clamping part in the embodiment. As shown in fig. 2, the ribs are divided into vertical ribs 4 and 6 and horizontal ribs 5, the vertical ribs 4 and 6 on the opposite side walls limit the circuit board in the horizontal direction, and the horizontal ribs 5 limit the circuit board in the vertical direction. Wherein the symmetry sets up buckle 2 on a set of opposite face of casing, and buckle 2 can adopt the pothook shape, directly realizes the buckle with the bayonet socket cooperation on pothook and another circuit board when fixed protective housing and is connected. For the dismouting of making things convenient for the protective housing, the middle part of buckle 2 place lateral wall is the strip and presses the splenium, and buckle 2 sets up in the outer edge of pressing the splenium, and horizontal bead 5 sets up on pressing the splenium inner wall. The two sides of the pressing part are respectively provided with a notch which can play a role in heat dissipation and is also beneficial to the pressing deformation of the pressing part. In order to form a good protection effect on the circuit board, the protection shell generally has a certain thickness and hardness, and in order to further facilitate pressing and increase the plastic deformation capacity of the protection shell, the pressing part and the position adjacent to the notch are recessed towards the inside of the shell to form a U-shaped through groove 3. Considering the heat dissipation requirement of the embedded circuit board, especially for a circuit with large power, the gap is still insufficient as a heat dissipation channel, so the embodiment further provides a vertical strip heat dissipation hole 1 on the side wall of the housing, and the heat dissipation hole 1 is disposed between the top surface of the housing and the gap. One of the effect of protective housing is just to make things convenient for electrified operation of inserting of pulling out, because embedded circuit board is close to the casing top surface relatively, if all lay louvre 1 at the whole lateral wall section of casing, in case handheld protective housing is pulled out the operation of inserting when being on hand relatively moist, and hand liquid can get into the danger that the circuit board caused the electric shock through louvre 1. Therefore, the heat dissipation holes 1 in this embodiment are only distributed at one end of the sidewall where the pressing portion is located, and the distribution length does not exceed the pressing portion, so as to avoid the above-mentioned danger of electric shock. When the circuit board is embedded, one end or a high-voltage end of the high-power device which is concentrated can face the position of the heat dissipation hole 1, so that heat dissipation is facilitated, and the operation safety can be ensured.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
