COUPLING DEVICE OF TEMPERATURE CONTROL SENSOR AND COPPER PIPE}

The present invention relates to a coupling device of the temperature control sensor and the copper tube, and more specifically, to insert a rivet as an intermediate medium so as to prevent the crack of the copper tube when the temperature control sensor and the copper tube is combined, and press the rivet work The copper tube and the temperature control sensor are coupled to each other, and the gap between the coupling parts between the parts is related to the coupling device of the temperature control sensor and the copper tube sealed by epoxy resin to complete the coupling.

Before describing the temperature control sensor, a pressure control sensor having a structure almost identical to that of the temperature control sensor will be described. Conventional pressure control sensor is an electronic or mechanical type, the electronic pressure control sensor detects the pressure of the intake air that is the measurement object and outputs the measurement signal to the control device.

The electronic pressure control sensor includes a sensor case, a connector pin, and a pressure sensor. The connector pin is connected to an external circuit which is a control device.

On the other hand, although a mechanical electronic sensor is used in the related art, the conventional mechanical pressure control sensor has a disadvantage in that there are many parts and a wide pressure control range.

In addition, the volume of the conventional mechanical pressure control sensor is large, the number of parts constituting the sensor there was a problem that the manufacturing cost is high. In addition, the actual operating pressure was not accurate and the market competitiveness with imported goods was poor.

According to the technology (patent application No. 10-2005-37823) filed by the applicant of the present invention to solve these disadvantages, the number of parts and the volume is small in a simple structure to improve the sensing ability and also inexpensive and compact A pressure control sensor of the type was provided.

1 and 2 are side cross-sectional views illustrating a state in which the conventional pressure control sensor is cut off by a pressure rise and an operation start state by a pressure drop, and as illustrated therein, a pressure control sensor according to the related art ( 100 is installed on the pressure-sensitive portion through the connecting member 90, the bellows 70 expands as the pressure of the pressure-sensitive portion rises, and the balance of force with the tension spring 46 (strength increase) The horizontal body portion 52 of the pressure transmission member 50 is rotated in a clockwise direction with the hinge point of the contact point between the protrusion 54 and the bellows 70 as a hinge point. Then, the switch operating member 49 is pushed to the right due to the rotation of the horizontal body portion 52 to block the switch.

The operation under pressure drops is as follows. As the pressure of the pressure-sensitive portion decreases, the bellows 70 contracts, thereby achieving a balance of force with the tension spring 46 (reducing tension), and the horizontal body portion 52 of the pressure transmission member 50 The contact point between the protrusion 54 and the bellows 70 is rotated counterclockwise as a hinge point. In addition, due to the rotation of the horizontal body portion 52, the switch operating member 49 moves to the left to operate the switch.

That is, the pressure control sensor as described above is composed of only the device that can connect the interior of the bellows 70 and the space in which the actual pressure acts (open type). Accordingly, the inside of the connection member 90 and the inside of the bellows 70 become the same pressure, so that the bellows 70 contracts and expands according to the pressure of the pipe to operate the switch.

On the other hand, a conventional temperature control sensor that operates in the same structure as the pressure control sensor described above will be described below. The same parts will be described using the same symbols. 3 is a view showing a conventional temperature control sensor, the basic structure and operation principle of the temperature control sensor and the pressure control sensor is the same. The temperature control sensor is connected to the inside of the bellows and the long copper tube in space, and closes the end completely after filling a specific gas inside. Accordingly, the temperature change in the copper tube causes a pressure change of the gas filled in the tube and the bellows, and accordingly, the bellows contracts and expands to operate the switch.

On the other hand, the following problems occurred when trying to combine with the copper tube for measuring the actual temperature through the temperature control sensor.

As shown in FIG. 3, in order to fix the copper tube 130 by inserting it into the bottom plate 82 of the temperature control sensor 100-1, the coupling portion of the copper tube 130 is pressed twice. Due to this, there is a problem that the folding part is excessively large, causing cracks, and consequently, a problem in which gas inside the copper tube 130 leaks to the outside (see point A in FIG. 3). In addition, after the press working of the copper tube 130, soldering was performed with lead 87 to prevent a gap in the joints between the parts. During the soldering operation, a different type of gas was formed inside the copper tube 130 by the reaction of heat and flux. There was a problem that acts as a factor that changes the temperature of the product. In addition, other kinds of gas has a problem that environmental pollution occurs as an environmentally harmful substance.

An object of the present invention has been proposed in order to solve the problems of the prior art as described above, to provide a coupling device of the copper tube and the temperature control sensor that can prevent the crack of the copper tube.

Still another object of the present invention is to provide a combination device of a temperature sensor and a copper tube so that the installation of the copper tube in the temperature control sensor can be completed easily and quickly.
