Description

  The present invention relates to an outdoor unit of an air conditioner including a terminal cover that covers a terminal portion of a compressor.

  Conventionally, an outdoor unit of this type of air conditioner includes a compressor and a blower, and a lead wire is connected to a terminal portion provided on the upper shell of the compressor. Further, a terminal cover is provided at the terminal portion of the compressor to which the lead wire is connected in order to prevent intrusion of moisture, dust and the like (see, for example, Patent Document 1).

  FIG. 7 is a perspective view of the conventional air conditioner outdoor unit described in Patent Document 1 except for the front plate, and FIG. 8 is a perspective view of a compressor mounted on the outdoor unit.

As shown in FIGS. 7 and 8, the outdoor unit 20 of the conventional air conditioner includes a compressor 21 and a terminal cover 22 of the compressor 21, and the terminal cover 22 is attached to the upper shell 23 of the compressor 21. A terminal accommodating portion 25 that covers the provided terminal portion 24, a hole portion 28 in which a stat bolt 26 provided in the upper shell 23 is inserted and fixed with a nut 27, and a lead wire 29 connected to the terminal portion 24. It is comprised from the taking-out opening 30 of this.
Japanese Patent Laid-Open No. 2002-5019

  However, in the configuration of the conventional outdoor unit of the air conditioner, the lead wire 29 connected to the terminal portion 24 of the compressor 21 is taken out from the takeout port 30 of the terminal cover 22 and the control plate of the main body control box 31 of the air conditioner. Although not connected, the compressor 21 is fixed with rubber or the like in order to prevent vibration during operation. Therefore, the compressor 21 behaves differently from the control plate during transportation and operation.

  In this case, in order to prevent excessive tension from acting on the lead wire 29, it is necessary to allow a certain amount of margin to the length of the lead wire 29. However, in recent years, the outdoor unit 20 has been reduced in size and performance. Accordingly, other parts such as pipes and electrical parts are also densely arranged around the compressor 21. Therefore, when the lead wire 29 has a margin, the lead wire 29 is provided between the outlet 30 and the control plate. There was a risk of contact with other parts and damage.

  In addition, when fixing is performed so that the lead wire 29 does not come into contact with other parts, the upper portion of the terminal cover 22 needs to be provided with a space for attaching and detaching the terminal cover 22 at the time of assembly or service. Around the compressor 21, the routing of the lead wire 29 is complicated. In addition, since the compressor 21 behaves differently from the fixed portion during transportation and operation, excessive tension acts on the lead wire 29, causing problems such as poor contact of the terminal portion 24 and breakage of the fixed portion. Was.

  The present invention solves the above-described conventional problems, and prevents the lead wire connected to the compressor from coming into contact with other parts and being damaged with an inexpensive configuration, and the lead wire is subjected to excessive tension. Therefore, an object of the present invention is to provide an outdoor unit of an air conditioner that does not cause a contact failure of the terminal portion.

In order to solve the conventional problems, an outdoor unit of an air conditioner according to the present invention includes a compressor and a terminal cover fixed to the compressor, and the terminal cover is provided on an upper shell of the compressor. A terminal accommodating portion for covering the terminal portion formed, a hole portion for inserting a stat bolt provided in the upper shell and fixing with a nut, a lead wire outlet connected to the terminal portion, and the lead wire The lead wire holding portion is formed in a hole shape so as to guide the lead wire taken out from the take-out port from the lower portion to the upper portion. After the lead wire connected to the terminal part is taken out from the terminal cover take-out port, it is passed through the hole that is the lead wire holding part from the lower part to the upper part. Approximately in the middle leads can be guided from bottom to top, the it is possible to prevent the lead wire and stud bolt, in contact with the other parts of the pipes and the like electrical components near the compressor. In addition, since the lead wire holding part is integrally formed with the terminal cover, the compressor and the lead wire holding part always behave the same, and excess tension does not act on the lead wire, resulting in poor contact of the terminal part. There is no risk of damage to the lead wire holding part.

  The outdoor unit of the air conditioner has an inexpensive configuration, prevents the lead wire connected to the compressor from coming into contact with other parts and is damaged, and the lead wire is not subjected to excessive tension. There is no fear of poor contact at the terminal.

  1st invention is equipped with the compressor and the terminal cover fixed to the said compressor, The said terminal cover covers the terminal part provided in the upper shell of the said compressor, The said upper shell A hole for inserting a stat bolt provided on the terminal and fixing with a nut; a lead wire outlet connected to the terminal; a lead wire for holding the lead wire and disposed in the vicinity of the stat bolt; The lead wire holding part is formed in a hole shape so as to guide the lead wire taken out from the take-out port from the lower part to the upper part, and the lead wire connected to the terminal part is a terminal. After being taken out from the cover outlet, the lead wire holding part is passed through the hole from the bottom to the top so that the lead is guided from the bottom to the top in the approximate center of the compressor. Is possible, it is possible to prevent the lead wire and stud bolt, in contact with the other parts of the pipes and the like electrical components near the compressor. In addition, since the lead wire holding part is integrally formed with the terminal cover, the compressor and the lead wire holding part always behave the same, and excess tension does not act on the lead wire, resulting in poor contact of the terminal part. And there is no risk of damage to the lead wire holder.

  In the second invention, in particular, one side of the lead wire holding portion of the first invention is a locking claw into which the lead wire can be inserted from the outside, and the lead wire is taken out in the lead wire drawing work. Since the lead wire can be inserted into the lead wire holding portion after being taken out from the connector and further connected to the control plate, an outdoor unit for an air conditioner with excellent workability in routing the lead wire can be provided.

  In the third invention, in particular, a fixing portion for fixing the sensor for detecting the temperature of the compressor of the first or second invention is formed integrally with the terminal cover, and the lead wire of the sensor is used as the lead wire of the terminal cover. Since the holding portion can be held together with the lead wire of the compressor, the lead wire routing workability can be improved.
