In order to solve such a problem, Korean Patent Registration No. 10-1162301 discloses a 'temperature sensor having a silicon housing and a manufacturing method thereof'.

Korean Patent Publication No. 10-1162301 discloses a temperature sensor in which a device and a portion of a wire covering are coated to form a primer layer so as to firmly bond the device and the wire covering to the silicon housing. Type in that it is a molding type in which the element and the wire covering are bonded to the housing.

The temperature sensor in the form of a housing consists of a wire and a housing electrically connected to the sensor, the sensor PCB, and the sensor PCB, and the housing is molded while the sensor, the PCB and the wires are connected.

When the temperature sensor is manufactured in the molding form in this way, the workability in the electronic product becomes very low if the length of the wiring is long when wiring the wire.

In addition, when a fault occurs due to an abnormality such as a sensor, a PCB, and a wire, the entirety can not be used, resulting in a problem of inefficiency in terms of recycling.

Hereinafter, preferred embodiments of a wire connector type temperature sensor according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a wire connector type temperature sensor according to the present invention connected to a wire.

As shown in FIG. 1, a wire connector type temperature sensor 10 according to the present invention is detachably connected to a plug type wire 11.

The plug type wire 11 includes two wires 11a for transmitting a signal of the temperature sensor 10 and a plug 11 which is connected to one end of the wire 11a to be plug- A 11c and a plug B 11b connected to the other end of the wire 11a to be plugged in and plugged into the connector of the temperature sensor 10 in a plug-in type.

The temperature sensor 10 is configured such that a connector is formed on one side and can be mounted and dismounted with the plug type wire 11. [

2 is an exploded perspective view of a wire connector type temperature sensor according to the present invention.

2, a wire connector type temperature sensor 10 according to the present invention includes an assembly 21, a temperature sensor body 22, and a housing 23. As shown in FIG.

The assembly 21 can be generally made of synthetic resin by injection molding, and can be composed of a base 21a and a connector 21b.

The base 21a functions to laterally support the temperature sensor body 22 and to insulate the two lead wires 22b of the temperature sensor body 22 and to electrically connect the two sensing wires 22b of the temperature sensor body 22 And to fix it.

The connector 21b is mechanically fastened to the plug B 11b of the plug type wire 11 and connects the two pin terminals of the plug B 11b and the lead wire 22b to electrically Connection.

The temperature sensor body 22 is a known temperature sensor in which the element 22a is molded at one end and two lead wires 22b for transmitting the signal of the element 22a are formed extending from the element 22a .

The housing 23 is made of a plastic material or a metal material and is used for protecting the temperature sensor body 22 and is covered with the temperature sensor body 22. The inside of the housing 23 is filled with epoxy, Cured.

FIG. 3 is a perspective view of an assembly of a wire connector type temperature sensor according to the present invention, and FIG. 4 is an assembled perspective view of an assembly and a temperature sensor in the wire connector type temperature sensor according to the present invention.

Referring to FIG. 3, the wire connector type temperature sensor according to the present invention includes an assembly 21, a temperature sensor body 22, and a housing 23.

The assembly 21 may be formed of a base 21a and a connector 21b and the base 21a may be composed of a body 211 and a hole forming body 213 and the connector 21b may be formed of a head 215, A guide 217, and a locking portion 218. [

The body 211 has a plate shape and may have a shape (W2 > W1) in which the width gradually decreases toward the tip, and a semicircular coupling groove 212 may be formed at the tip.

The body 211 functions to insulate the two lead wires 22b of the temperature sensor body 22 and to closely contact the two lead wires 22b. The width of the lead wire 22b is gradually increased toward the hole forming body 213 in order to increase the adhesion and the coupling force of the lead wire 22b.

The width of the body 211 gradually increases in order to match the width of the lead wire 22b with the distance between the two terminals formed on the plug B 11b.

The tip end portion of the body 211 is spaced apart from the gap of the lead wire 22b connected to the element 22a of the temperature sensor body 22 and the gap between the lead wire 22b connected to the terminal of the plug B 11b It is preferable that the width of the body 211 is variably formed.

The engaging groove 212 is formed in a semicircular shape, which has the effect of further extending the surface leakage distance for preventing the short-circuit between the lead wires 22b as a part where the element 22a is seated.

Referring to FIG. 4, a configuration in which the temperature sensor body 22 is assembled to the assembly 21 is shown.

The temperature sensor body 22 is formed such that the element 22a is mounted on the coupling groove 212 and the lead wire 22b is tightly coupled to the body 211 on both sides with respect to the body 211, And the end portion is passed through the through hole 214 and protrudes into the plug receiving portion 216.

The two strands of the projected lead wire 22b serve as a pin connected to the two terminals of the plug B (11b).

As shown in FIG. 4, the housing 23 is coupled with the assembly 21 and the temperature sensor body 22 in a combined state. At this time, the epoxy 23 is filled in the housing 23 with epoxy before curing, .

The epoxy serves as an insulator and serves to fix the temperature sensor body 22 and the assembly 21.

The temperature sensor of the present invention can work in an electronic product or the like while the temperature sensor portion and the wire portion are separated.

In other words, the position where the temperature sensor can be mounted is determined in the inside of the electronic product. When the temperature sensor is set only in the correct position, the plug B And the head 21b and the head 215 are connected to each other, thereby simplifying the wiring work.

In the conventional molding type temperature sensor, electrical wiring work is performed in a state where the wire and the temperature sensor are formed as a body, so that there is a disadvantage that cable wiring work such as a long wire is not easy.

Further, in the temperature sensor of the present invention, when the cable and the temperature sensor are finally combined and assembled into a connector, if there is an abnormality in the wire or the temperature sensor, the portion where the wire contacts the temperature sensor is cut, The wire can be recycled, but if the cable or the temperature sensor part is defective, there is no new way to connect it, so the cable and the temperature sensor become bad and there is no room for recycling.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, As will be understood by those skilled in the art. Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
