Abstract

This invention discloses a control box structure. It contains box body with printed circuit board, hanging convex fixed on back surface to form connection convex, hook convex on hang convex. Said invention reduces screw number, can firmly fixes box with reduced assembling space.

Description

The fixed structure of control box

Technical field

The invention relates to the installation of control device, specifically is the fixed structure that the control box of dress tellite in a kind of handle is set to the control box in the electrical equipment such as refrigerator.

Background technology

In general, possesses the tellite that the refrigerator of freezing cycle device or various electric equipment products all possess the various functions of control (following use with) with printing distributing board.When cold media gas was revealed, this printing distributing board might produce spark and blast.Based on this reason, printing distributing board is set to the Machine Room of refrigerator after control box is put into the safety-deposit box that separates with the outside.

Fig. 1 is the decomposing schematic representation of prior art control box fixed structure.

As shown in the figure, the control box that possesses set inner space in the prior art is by constituting as the lower part: the box body 1 of printing distributing board is installed by portion within it; Both sides several (in drawings 4) of prolong forming connect protuberance 2 to the left and right near the base angle of box body 1, connection protuberance 2 are affixed to several (in the drawing 4) connecting screws of compressor base portion or bottom surface, Machine Room 3.

The bottom surface that connects protuberance 2 is consistent with the bottom surface of box body 1, and the connection protuberance 2 of every side prolongs to the same side respectively and forms; Be formed with the connecting hole 2a that connects connecting screw 4 at its end.

Undeclared symbol 3a is a screw hole in the drawing.

Based on the control box of above-mentioned prior art, the fixation procedure of its fixed structure is as follows.

After necessary printing distributing board (not shown) is installed to box body 1, box body 1 is put into the bottom surface, Machine Room 3 of refrigerator or the face that is provided with of compressor; The connecting hole that the connection protuberance 2 of box body 1 is possessed and bottom surface, Machine Room or compressor are provided with screw hole that mask is equipped with aim at after, utilize several screws to be connected and fixed one by one.

But, as above have following deficiency in the fixed structure of control box.For held stationary box body 1, need 4 connecting screws 4 to connect at least on the connection protuberance 2 that possesses at each base angle.Most connecting screws 4 along with needs have not only increased number of spare parts, also make assembling procedure complicated, and have increased producing cost.

Summary of the invention

Deficiency in view of the fixed structure of control box in the prior art exists the purpose of this invention is to provide a kind of connecting screw that reduces the fixed bin body, thereby reaches the fixed structure that simplifies assembling procedure and reduce the control box of producing cost.

In order to reach purpose of the present invention, the fixed structure of control box of the present invention comprises the box body that printing distributing board is installed; One side of its box body is formed with and is inserted into the face of setting and the slotting extension protuberance of fixing of hanging; Hang protuberance insert hang be fixed to the face of setting after, in order to couple together, be formed with the connection protuberance at the opposite side of box body with the key screw opposite side.

Extension protuberance that the present invention has hooked into the face of setting because of a side of box body has formed with formed the protuberance that is connected that connecting screw uses at opposite side, thereby reduced assembling space and reached the minimizing connecting screw to use number, firmly fix control box, have the advantage of simplifying assembling procedure and reducing producing cost.

Embodiment

Describe the present invention below in conjunction with drawings and Examples.

Fig. 2 is the decomposing schematic representation of control box fixed structure of the present invention; Fig. 3 is that the vertical profile master of control box fixed structure of the present invention looks schematic diagram; Fig. 4 is the enlarged diagram of Fig. 3 " A " portion assembling sequence.

As shown in the figure, based on control box of the present invention, the one side is to insert to hang to be fixed to the face of setting, and opposite side then utilizes connecting screw to be connected and fixed.

For as above purpose, the side that the box body 10 of printing distributing board is installed is protruded downwards and has been formed a plurality of hook portion 11, and the opposite side of box body 10 protrudes to the side and formed a plurality of connection protuberances 12.

For hook portion 11 being inserted into the hanging groove 21 of the face of setting 20, and will going up the side direction hook and fix, and during side projection, hang protuberance 11 and form " " shapes; Fix direction of insertion, be in-plane in order to be suspended to suspension hook groove 22 and hook, formed reverse suspension hook projection 11a above the end of hook portion 11.

The bottom surface of the connection protuberance 12 that prolongation forms and the bottom surface of box body 10 have formed the connecting hole 12a that connects connecting screw 30 on same plane on it.

Simultaneously, be provided with on the face, be provided with and be formed with the hook portion 11 that makes box body 10 and insert downwards at the bottom surface or the compressor of refrigerator mechanical chamber, and the hanging groove 21 that can tangle upward; Hanging groove 21 1 sides be formed with suspension hook projection 11a is inserted hang and with the suspension hook groove 22 of hanging groove 21 on same horizontal line.

Bottom surface or compressor at refrigerator mechanical chamber are provided with on the face, have also formed the connecting hole 12a that possessed with the connection protuberance 12 of box body 10 at the consistent screw hole 23 of vertical direction.

Aforesaid control box fixed structure of the present invention has following effect.

Printing distributing board (not shown) is installed in the control box body, on this printing distributing board, has connected the lead (not shown) with the outside terminal electrical communication, then, control box is set to the Machine Room of refrigerator or the face that is provided with 20 of compressor.

For being fixed to Machine Room or compressor etc., box body 10 is provided with on the face, the extension protuberance 11 that the rear side both sides of box body are possessed is to arrow after 1. the below is inserted into the hanging groove 21 of the face of setting 20, toward the rear be arrow 2. direction push away, extension protuberance 11 is suspended on the face of setting, thereby it can't be come off from top.In this process, the suspension hook projection 11a that possesses at extension protuberance 11 ends is inserted into the suspension hook groove 22 that the face of setting 20 possesses, and making it can be not that the front side, plane comes off from direction of insertion.

Then, adjust both sides, box body 10 front side and connect the connecting hole 12a that protuberance 12 possesses, after making it and the screw hole 23 that face 20 is set being consistent, utilize two connecting screws 30 that the connection protuberance 12 of box body 10 is connected on the face of setting 20.

By as above process, not only reduced the use number of connecting screw, also Machine Room or the compressor that box body firmly is fixed to refrigerator is provided with face.Reduce assembling procedure, reduced number of parts, reached the purpose that reduces producing cost.
