It should be noted that the technical features of the embodiments and alternative embodiments of the present invention may be combined with each other without conflict.

In order to solve the above problems, the present invention provides an ice maker and a refrigerator. Fig. 1 illustrates an overall structural schematic view of a refrigerator according to an embodiment of the present invention. Fig. 2 shows an enlarged schematic view of a region B of the refrigerator of fig. 1. As shown in fig. 1-2, an ice maker 200 may be provided in a freezing chamber of the refrigerator 100, mainly by making ice cubes by means of cooling energy of the refrigerator 100. Fig. 3 shows a first overall structural schematic diagram of an ice maker according to an embodiment of the present invention. Fig. 4 shows a second overall structural schematic diagram of the ice maker according to the embodiment of the present invention. Fig. 5 shows a cross-sectional view of the ice maker of fig. 4 along the line a-a. As shown in fig. 3-5, the ice maker 200 includes a connection terminal 210 and a housing 220. The connection terminal 210 includes a main body 211, and a first limiting portion 212 and a second limiting portion 213, which are formed by two sides of the main body 211 and extend outward to form different shapes. An electrical terminal is disposed in the body portion 211, and one end of the body portion 211 forms an electrical connection end 2111 to which the electrical terminal is connected. The housing 220 has an opening 221, and the housing 220 has a terminal fixing cavity 222 communicating with the opening 221 and receiving the connection terminal 210 therein, so that the electrical connection end 2111 of the body portion 211 mounted in the terminal fixing cavity 222 is exposed to the opening 221. The terminal fixing cavity 222 is formed with a first limiting cavity 223 and a second limiting cavity 226 respectively matched with the first limiting part 212 and the second limiting part 213.

In this embodiment, the first and second position-limiting

parts

212 and 213 have different shapes, and the terminal fixing cavity 222 is formed with a first position-limiting cavity 223 and a second position-limiting cavity 226 respectively matched with the first and second position-limiting

parts

212 and 213, so that the error-proof reliability is high, and the condition that the ice maker 200 fails due to the reversed installation of the connection terminal 210 is avoided.

The electrical terminals in the body portion 211 are specifically led out by an ice making assembly of the ice maker 200, and in an alternative embodiment, an ice making chamber 230 is further provided inside the housing at one side of the terminal fixing chamber 222, and the ice making assembly may be provided in the ice making chamber 230. The electrical connection end 2111 of the main body portion 211 connected to the electrical terminal may be connected to a main control board of the refrigerator 100, and may be used for signal transmission between the refrigerator 100 and the ice maker 200 and also for power transmission.

In an alternative embodiment, as shown in fig. 5, the first position-limiting portion 212 has a notch 2121 and a notch 2122 formed on a side thereof away from the main body portion 211, and the notch 2121 and the notch 2122 are preferably triangular notches. The first limiting cavity 223 is provided therein with a convex portion 224 and a convex portion 225, the convex portion 224 and the convex portion 225 are triangular ribs adapted to the positions and shapes of the notch 2121 and the notch 2122, respectively, and the first limiting portion 212 can be smoothly pushed into the first limiting cavity 223 under the condition that the convex portion 224 is matched with the notch 2121 and the convex portion 225 is matched with the notch 2122. And because first spacing portion 212 and second spacing portion 213 appearance are different, when reverse assembly binding post 210, spacing portion 213 of second can be blocked by bellying 224 and bellying 225, and the commentaries on classics fit into, has effectively prevented to adorn the condition emergence of turning over binding post 210.

In the present invention, the shape and number of the notches and the protrusions are not particularly limited.

Further, fig. 6 is a schematic view showing a first state of the connection terminal of the ice maker according to the embodiment of the present invention in the terminal fixing chamber. Fig. 7 is a schematic view showing a second state of a connection terminal of an ice maker according to an embodiment of the present invention in a terminal fixing chamber. As shown in fig. 6-7, in an alternative embodiment of the present invention, a limiting member 227 and a limiting member 228 may be respectively formed on the side walls of the first limiting cavity 223 and the second limiting cavity 226, a limiting space (not shown) is formed between the limiting member 227 and the end wall of the first limiting cavity 223 along the direction parallel to the opening 221, and a limiting space 229 is formed between the limiting member 228 and the end wall of the second limiting cavity 226 along the direction parallel to the opening 221, so as to respectively limit the first limiting portion 212 and the second limiting portion 213 in the respective limiting spaces.

Specifically, the limiting

members

227 and 228 may be elastic limiting members, the extending directions of the

limiting members

227 and 228 are the same as or opposite to the direction of the opening 221, and when the first limiting portion 212 and the second limiting portion 213 move to the respective limiting spaces, the limiting

members

227 and 228 are compressed by the first limiting portion 212 and the second limiting portion 213 to be in the non-limiting state close to the respective sidewalls; when the first position-limiting portion 212 and the second position-limiting portion 213 reach the respective position-limiting spaces, the position-limiting

members

227 and 228 both rebound and return to their original positions and are in the position-limiting state away from the respective side walls. The first and second position-limiting

portions

212 and 213 can be respectively limited in the respective position-limiting spaces, and the first and second position-limiting

portions

212 and 213 are prevented from sliding in a direction away from the respective position-limiting spaces.

It should be noted that fig. 6-7 show that the limiting member and the rear end wall of the limiting cavity form a limiting space, and in practical applications, the limiting member and the front end wall of the limiting cavity may also form a limiting space.

The invention provides an ice maker 200 and a refrigerator 100, wherein a terminal fixing cavity 222 is provided with a first limiting cavity 223 and a second limiting cavity 226 which are respectively matched with a first limiting part 212 and a second limiting part 213 of a wiring terminal 210, wherein the shapes of the first limiting part 212 and the second limiting part 213 are different from those of the wiring terminal 210, so that the error-proof reliability is high, and the condition that the ice maker 200 fails due to the fact that the wiring terminal 210 is reversely arranged is avoided; in addition, a limiting member 227 and a limiting member 228 are respectively arranged on the side walls of the first limiting cavity 223 and the second limiting cavity 226, a limiting space is formed between the limiting member 227 and the end wall of the first limiting cavity 223 along the direction parallel to the opening 221, and a limiting space 229 is formed between the limiting member 228 and the end wall of the second limiting cavity 226 along the direction parallel to the opening 221, so that the first limiting portion 212 and the second limiting portion 213 can be respectively limited in the respective limiting spaces to prevent the first limiting cavity 223 and the second limiting cavity 226 from sliding.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
