본 발명은 인입선이 매입된 과부하 보호장치의 보호커버, 보다 상세하게는 압축기의 운전시 발생되는 과열을 감지하여 그 동작을 제어하는 과부하 보호장치의 단자와 전원터미날단자가 인입선으로 이어지고 그 위에 보호커버가 씌워지는 것을 일체화하여 과부하 보호장치의 보호커버에 매입함으로써 부품단순화 및 작업시간이 단축 되도록 한 인입선이 매입된 과부하 보호장치의 보호커버에 관한 것이다.The present invention is a protective cover of the overload protection device in which the lead wire is embedded, more specifically, the terminal and the power terminal terminal of the overload protection device for detecting the overheat generated during operation of the compressor to control the operation of the overload protection device leads to the lead wire and the protective cover thereon This invention relates to a protective cover of an overload protection device in which a lead wire is embedded so that the parts are simplified and the working time can be shortened by embedding the cover into the protection cover of the overload protection device.
일반적으로, 공기조화기에 설치된 압축기는 증발기에서 유입되는 저온, 저압의 기체냉매를 흡입하여 고온, 고압의 기체 냉매로 압축시키는 작용을 한다.In general, the compressor installed in the air conditioner serves to suck the low-temperature, low-pressure gas refrigerant flowing from the evaporator to compress the high-temperature, high-pressure gas refrigerant.
상기 압축기의 동작에 의해 압축된 냉매는 응축-팽창-증발 등의 냉동싸이클을 반복적으로 순환하면서 냉각기를 통과하는 주위의 공기의 열을 흡수하여 차가운 공기를 배출하는 소위 열교환 작용에 의해 냉방을 하게 된다.The refrigerant compressed by the operation of the compressor is cooled by a so-called heat exchange effect that absorbs heat of ambient air passing through the cooler and discharges cold air while repeatedly circulating a refrigeration cycle such as condensation-expansion and evaporation. .
이러한 압축기는 냉매를 고압으로 압축하기 위해 비교적 높은 회전속도와 토오크를 요구하게 되므로 이 과정에서 많은 열이 발생되었고, 특히 초기 운전시 또는 재기동시에는 과전류가 유기되면서 과부하로 인한 과열이 발생하였다.Since the compressor requires a relatively high rotation speed and torque to compress the refrigerant to a high pressure, a lot of heat is generated in this process. In particular, during initial operation or restarting, overheating is induced while overcurrent is induced, causing overheating.
이처럼 압축기의 동작시 집중적인 과열이 발생되는 상측부에 과열상태를 감지하여 압축기의 동작을 적절히 제어하기 위한 과부하 보호장치의 단자의 하나가 전원터미날단자의 하나와 인입선으로 연결되어 있었다.As described above, one terminal of the overload protection device for controlling the operation of the compressor by detecting an overheating state in the upper part where intensive overheating occurs during operation of the compressor was connected to one of the power terminal terminals by a lead wire.
제1도는 종래의 공기조화기 압축기의 측면도이고, 제2(a)(b)도는 종래의 공기조화기 압축기의 평면도 및 상부측면도로서, 압축기 몸체(1)의 상부를 밀폐시키는 상부캡(2)에 설정온도 이상의 과열 발생시 제어신호를 보내는 과부하 보호장치(6)가 착설되어 그를 보호하는 보호커버(3)가 씌워져 있으며, 이의 외측에는 전원 터미널단자(4)가 설치되어 인입선(5)으로 연결되어 있었다.1 is a side view of a conventional air conditioner compressor, and FIG. 2 (a) (b) is a plan view and a top side view of a conventional air conditioner compressor, and an upper cap 2 for sealing an upper portion of the compressor body 1 is shown. Overload protection device (6) that sends a control signal in the event of overheating above the set temperature is installed, and a protective cover (3) is provided to protect it. On the outside thereof, a power terminal (4) is installed and connected to the lead wire (5). there was.
따라서, 상기 과부하 보호장치(6)는 상부캡(2)으로부터 전도되는 온도를 감지하여 설정치 이상의 온도가 감지될 경우 상기 인입선(5)을 통하여 제어신호를 터미날단자(4)로 전달함으로써 공급되는 전원을 차단하여 압축기를 보호하고 일정시간이 지나면 전원공급을 재게하는 작용을 한다.Therefore, the overload protection device 6 detects the temperature conducted from the upper cap 2, and when a temperature higher than a set value is detected, the power supplied by transmitting a control signal to the terminal terminal 4 through the lead wire 5. It protects the compressor by blocking the power supply and restarts the power supply after a certain time.
그러나, 상기 인입선의 일측이 과부하 보호장치의 단자에 고정되어 있어 먼저 과부하 보호장치의 보호커버를 취부하고 나서 인입선을 전원 터미날단자에 연결되도록 작업이 이루어져 작업시간이 길어지고 연결하는 과정에서 정확히 접속되지 않아 압축기를 보호하지 못하는 등의 문제점이 있었다.However, since one side of the lead wire is fixed to the terminal of the overload protection device, the protective cover of the overload protection device is first mounted, and then the lead wire is connected to the power terminal terminal, so that the working time is long and the connection is not made correctly. There was a problem such as not protecting the compressor.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로, 그 목적은 과부하 보호장치의 단자와 전원 터미날단자를 연결하는 인입선의 역할을 과부하 보호장치의 보호커버가 대신함으로써 부품의 단수화 및 작업시간을 단축함과 동시에 압축기를 보호하는 것이다.The present invention has been made to solve the conventional problems as described above, the object of which is to replace the part of the lead wire connecting the terminal of the overload protection device and the power terminal terminal with the protective cover of the overload protection device to reduce the number of parts and It shortens working time and protects compressor.
이러한 본 발명의 목적은 전원 터미날단자와 과부하보호장치의 하나의 단자에 각각 접속되는 접속홈이 형성된 보호커버를 사용함으로써 달성된다.This object of the present invention is achieved by using a protective cover formed with a connection groove connected to each of the power terminal and one terminal of the overload protection device.
상기와 같은 목적을 달성하기 위하여 본 발명은, 작업자가 보호커버를 과부하 보호장치에 취부할 때 접속홈에 터미날단자가 접속되게 취부함으로써 작업시간이 단축되고 부품이 단순화됨을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the work time is shortened and the parts are simplified by attaching the terminal terminal to the connection groove when the worker attaches the protective cover to the overload protection device.
이하, 본 발명의 실시예의 인입선을 겸한 과부하 보호장치의 보호커버를 첨부된 도면에 의거하여 상세히 설명한다.Hereinafter, a protective cover of an overload protection device serving as a lead wire according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
