For example, the refrigerator body may be provided with the reed switch assembly, and the door may be provided with the magnet for generating a magnetic force.

1, the reed switch assembly includes a case 10, a sensor 30 accommodated in the case 10, and a wire 40 connected to the sensor 30 do.

The case 10 is formed with a receiving space in which one side is opened.

The sensor (30) is accommodated in the case (10).

Although not shown in the figure, a support means for the sensor 30 is provided inside the case 10.

The sensor (30) includes a container (31) for forming a receiving space therein, and one end of the sensor (30) is disposed so as to be in contact with the inside of the container (31) And leads 35 exposed at both ends.

The lead 35 is formed of a magnetic material.

The leads 35 are spaced apart from each other by their own elasticity.

The inner ends of the leads (35) are brought into contact with the inner ends disposed inside the main body by the magnetic force when the magnets approach each other. The ends of the leads (35) return to the initial positions by elasticity of the magnets And are separated from each other and separated.

A wire 40 is connected to the lead 35, respectively.

A bonding portion 45 is provided at the boundary between the lead 35 and the wire 40.

The lead 35 and the wire 40 are usually joined by a method such as soldering.

However, in such a conventional reed switch assembly, the lead 35 and the wire 40 of the sensor 30 are very small in size and thin, which requires much time and effort in welding (soldering) work.

In addition, when the wire 40 is pulled out of the case 10, there is a problem that the bonding portion 45 between the lead 35 and the wire 40 can be separated.

The wire 40 and / or the lead 35 may be corroded by moisture in the air when the wire 40 and the lead 35 are exposed to the air.

Whereby the life of the reed switch assembly can be shortened.

Further, since the lead 35 is bent in a direction away from the magnet and connected to the wire 40, the sensing distance for sensing the magnetic force of the magnet can be shortened.

There is a problem in that the size of the magnet (magnetic force) is increased in consideration of this.

In addition, when the lead 35 is extended in the longitudinal direction of the container 31 to increase the sensing distance, the size of the case 10 in the width direction may be increased, which may make the compact configuration difficult.

Meanwhile, as shown in FIGS. 4 to 6, the reed switch assembly 160 according to an embodiment of the present invention includes a case 170 forming a receiving space therein; The container 231 and each one side are arranged so as to be spaced apart from each other inside the container 231 and each other is drawn out of the container 231. The other end of the container 231, A sensor (230) provided inside the case (170) with a sensor (233); And a wire (250) having terminals (260) which are electrically connected to each other in a longitudinal direction of each of the leads (233) in a transverse direction.

The reed switch assembly 160 shown in the drawings of the present embodiment is shown enlarged (for example, enlarged to three to four times the size) larger than the actual size for the sake of convenience of explanation of the drawings, May be configured smaller than the size shown.

The case 170 includes a first case or a body 171 (hereinafter, referred to as a 'body 171') having a receiving space formed therein and a second case or body 171 A case or a cover 210 (hereinafter referred to as a cover 210).

Each of the leads 233 may have a bent end 235 that is laterally bent in the longitudinal direction of the lead 233, for example.

Each of the bent ends 235 is bent in the thickness direction of the body 171 (lower side in the drawing).

Since the distance between each bent end 235 and the magnet 150 is the same, the sensing distance that can be affected by the magnetic force is not shortened and maintained, and the length along the length of the container 231 is reduced have.

According to this configuration, the overall length of the sensor 230 (the length along the lateral direction of the case 170) can be reduced while the sensing distance of each sensor 230 is maintained.

Thus, the width W of the case 170 along the left and right direction of the refrigerator body 110 can be reduced.

7, the wire 250 includes an energizable conductor 251, a covering member 252 surrounding the conductor 251, and a terminal 260 connected to the conductor 251. [ As shown in FIG.

The conductor 251 may be composed of a plurality of wires (enamel wires) having a predetermined diameter, for example.

One end of the conductor 251 of each wire 250 may be connected to the lead 233 of the sensor 230, respectively.

The other end of the conductor 251 of each wire 250 may be connected to the control unit 280, for example.

According to such a configuration, a contact signal (for example, a door closing signal) may be transmitted to the control unit 280 when the lead 233 is contacted.

The cover member 252 may be formed of an electrically insulating member, as is well known.

The terminal 260 includes a coupling piece 261 coupled to the conductor 251, a connection piece 265 electrically connected to the lead 233 of the sensor 230, 261 and a connecting piece 263 connecting the connecting piece 265 to each other.

The coupling pieces 261 may be composed of, for example, a plurality of coupling pieces.

One side of the coupling piece 261 is connected to the conductor 251 so as to be electrically energetrically wrapped around the conductor 251 and to be physically and integrally coupled with the end of the conductor 251 by being plastic- have.

The other side of the engagement piece 261 may be coupled to the periphery of the cover member 252, for example.

The connecting piece 265 may have a protrusion 266 that protrudes in the width direction as compared with the outer width of the conductor 251 or the covering member 252, for example.

The connecting piece 265 may be formed to protrude from both sides of the conductor or the covering member 252, for example.

With such a configuration, both sides of the connecting piece 265 can be stably supported by being inserted into and supported by the case 170 when the connecting piece 265 is received inside the case 170. [

A lead insertion portion 267 may be formed in the connection piece 265 so that the lead 233 of the sensor 230 can be inserted.

The lead inserting portion 267 may be formed to be relatively small as compared with the outer diameter (outer width) of the lead 233 of the sensor 230.

The lead 233 may be press-fitted into the lead insertion portion 267.

With this structure, it is possible to reduce the gap between the lead 233 and the lead inserting portion 267 to prevent the connection failure between the sensor 230 and the connecting piece 265.

More specifically, when the inner width of the lead insertion portion 267 is formed larger than the outer width of the lead 233 because the actual size of the lead 233 and the connection piece 265 is very small, The contact area between the lead 233 and the connecting piece 265 of the lead frame 230 may not be secured sufficiently to cause a connection failure. However, the lead 233 and the lead inserting portion 267 of this embodiment may be press- The occurrence of connection failure can be suppressed.

At the entrance of the lead insertion portion 267, for example, a guide inclined portion 268 may be formed to guide the lead 233.

The guide inclined portion 268 may be formed such that the inner width gradually increases toward the outside as compared with the lead insertion portion 267, for example.

The connecting piece 265 may include a guide portion 269 for guiding the coupling when the case 170 and the cover 210 are engaged.

For example, the guide portion 269 may be formed such that its outer width is gradually reduced toward the outer side along the protruding direction of the protruding portion.

The connecting piece 265 may be provided with a bead 270, for example.

Thus, deformation of the connecting piece 265 can be suppressed at the time of press-fitting.

On the other hand, a waterproofing treatment portion 270 is provided around the lead 233 and the connecting piece 265 so that contact with moisture (moisture in the air) can be suppressed, for example, as shown in FIG. 9 .

More specifically, the waterproof processing unit 270 may be formed by coating silicon with a predetermined thickness around the leads 233 and the terminals 260 after the connection between the leads 233 and the terminals 260 .

This prevents the leads 233 and the connecting pieces 265 from being in direct contact with the moisture in the air, so that corrosion of the leads 233 and the connecting pieces 265 can be suppressed.

The waterproof processing unit 270 may be implemented to have a thickness that is small enough to be accommodated in the case 170, for example.

10, the body 171 of the case 170 includes a front plate 172, a rear support 173 disposed opposite to the front plate 172, And a side support portion 174 provided on both sides of the plate portion 172 and the rear support portion 173.

The rear end of each of the connecting piece receiving portions 182 may be provided with a latching protrusion 184 for contacting the protruding portion 266 of the connecting piece 265 accommodated therein.

The protrusion 266 and the engaging protrusion 184 are engaged with each other with respect to the pulling direction of the wire 250 when the wire 250 is pulled outward (actually, the rear side of the case 170) So that the tensile force acting on the wire 250 can be prevented from being transmitted to the connection region of the terminal 260 and the lead 233.

Thus, separation (separation) of the wire 230 from the wire 250 due to pulling of the wire 250 can be suppressed.

Further, in the present embodiment, the lead 233 is relatively moved outward relative to the container 231 due to the pulling of the wire 250, so that the gap between the inner ends of the leads 233 is opened , So that there is no possibility that a malfunction occurs in which the two ends are not brought into contact with each other even if a magnetic force acts.

The reed switch assembly 160 may be coupled to the reed switch engaging part 127 of the refrigerator body 110.

When the door 140 (the freezing chamber door 141) is rotated in the closing direction, the magnet 150 can be accessed to the reed switch assembly 160.

The ends of the leads 233 on the inner side of the container 231 can be brought into contact with each other by the magnetic force of the magnets 150.

Accordingly, the control unit 280 may detect the closing of the freezing chamber door 141.

The control unit 280 may turn off the illumination light of the freezing chamber 121 when the freezing chamber door 141 is closed.

When the freezing chamber door 141 is opened, the end of the lead 233 of the sensor 230 disposed inside the container 231 may be returned to the initial position by the elasticity of the freezing chamber door 141 and may be spaced apart from each other.

Accordingly, the control unit 280 senses the opening of the freezing chamber door 141 and can turn on the illumination lamp in the freezing chamber 121.
