Description

[0001] JIG APPARATUS FOR C-CUP BONDING THERMISTOR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jig for C cup bonding of a thermistor, and more particularly, to a jig for C cup bonding of a thermistor for pressing and fixing a C cup bonding state of a thermistor and a sensor cover.

2. Description of the Related Art Generally, a thermistor is a semiconductor device that measures temperature using a change in resistance of a ceramic material with temperature, and is used by being electrically connected to various electronic parts through lead wires. The thermistor is classified into a bead type, a disk type, a chip type, a bar type, and the like depending on the external shape and manufacturing method.

 In particular, in the case of a bar type thermistor, as shown in FIGS. 1 and 2, the thermistor 10 is connected to the rear surface of the lead wire W so as to be electrically connected to the electronic component in a bar shape.

Here, the thermistor 10 is connected to the sensor cover 20 in a C cup bonding manner so as to be easily inserted and fixed on various electronic parts without being limited to the temperature measurement function while protecting the internal elements. The sensor cover 20 is shaped like a C cup to accommodate the side surfaces and the bottom surface of the thermistor 10 so as to protect the internal elements of the thermistor 10 and has a plurality of ribs 21 projecting from the inner side surface, The lead wire receiving groove 22 is recessed.

The C cup bonding between the thermistor 10 and the sensor cover 20 is performed by applying an adhesive to the bottom surface of the thermistor 10 or the inner bottom surface of the sensor cover 20, Are inserted into the sensor cover (20) and bonded to each other.

At this time, it is necessary to pressurize the thermistor 10 and the sensor cover 20 for a predetermined time so that the bonding force is maintained while the height of the top surface of the thermistor 10 and the sensor cover 20 is matched while the adhesive is cured. This is because if the bonding surfaces of the thermistor 10 and the sensor cover 20 are not completely tightly adhered to each other and the adhesive is hardened, the bonding force between the thermistor 10 and the sensor cover 20 deteriorates, .

As shown in FIG. 3, the operation of pressing the thermistor 10 and the sensor cover 20 for a predetermined time to fix the C-cup bonding state is mainly performed by the operator manually pressing the thermistor 10 and sensor And pressing the upper and lower surfaces of the cover 20, respectively. Alternatively, although not shown in the drawings, the C cup bonding state may be fixed by being inserted into a clip and a clamp. This is because the operator does not have a dedicated jig device capable of fixing the C-cup bonding state of the thermistor 10 and the sensor cover 20 having a bar shape one by one.

However, the above-described conventional C cup bonding fixing method of the thermistor 10 and the sensor cover 20 has to be fixed one by one depending on the hands, clips or clamps of the first operator. Secondly, when the pressure is directly applied by a worker's hand, the degree of pressure is insufficient, resulting in a product failure due to a decrease in the bonding force. In the case of pressing with a clip or a forceps, the degree of pressure may be excessively damaged. Third, since the fixing time of the C-cup bonding state can not be constantly performed, defective products cause defective products if the fixing time is short, and work efficiency decreases when the fixed time is exceeded.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems described above. First, the present invention provides a C-cup bonding method of a thermistor capable of significantly improving the operational efficiency compared with the conventional fixing method by simultaneously fixing a plurality of thermo- And to provide a jig device.

Second, since the C cup-bonded thermistor and the sensor cover are inserted and fixed while being pressed up and down, a jig for C cup bonding of the thermistor is provided which improves the bonding force compared to the conventional fixing method and can prevent breakage and product defect. .

Third, it is an object of the present invention to provide a jig for C-cup bonding of a thermistor, which can fix the C-cup bonding state constantly, thereby preventing product defects and greatly improving work efficiency compared to the conventional fixing method.
