[0002] With the improvement of living standards, refrigerators have become indispensable household appliances. In order to realize the complex functions of refrigerators, many wire harnesses are required to transmit signals between the refrigerator body and the door.

[0003] At present, the connection terminal between the refrigerator body and the door is set at the upper end of the refrigerator door. When the installer plugs in the connection terminal, if there is no auxiliary tool such as a ladder, the connection end of the connection terminal cannot be seen, and blind plugging is required. However, conventional connection terminals have a fool-proof structure design, and the corresponding positions of the connection head and the connection terminal must be distinguished before insertion. Therefore, blind plugging cannot be achieved, which makes the plug-in installation process of the connection terminal very inconvenient. Summary of the invention

[0004] The object of the present invention is to provide a wiring terminal and a refrigeration device having the same, so as to solve the above-mentioned problem.

[0005] To achieve one of the above-mentioned purposes of the invention, the present invention provides a terminal block, which comprises: a male end component, the male end component comprises a base, a plurality of terminals protruding from the base, the base having a plug-in end face, the plurality of terminals being evenly arranged on the plug-in end face around the center of the plug-in end face, and the plurality of terminals having different protruding lengths; a female end component, the female end component comprises a plurality of slots for the terminals to be inserted, each of the slots being provided with an elastic conductive member docking with the terminals, the female end component also comprising a plurality of wire loops spaced apart along the extension direction of the slots, the elastic conductive member being used to electrically connect the wire loops with the corresponding terminals.

[0006] As a further improvement of the present invention, the elastic conductive part is provided with a pin on the side close to the notch of the slot, and the terminal is provided with an alignment groove matching with the pin on the side away from the plug-in end face; or the elastic conductive part is provided with an alignment groove on the side close to the notch of the slot, and the terminal is provided with a pin matching with the alignment groove on the side away from the plug-in end face.

[0007] As a further improvement of the present invention, the female end component includes a cylindrical fixed seat and a movable seat connected to the fixed seat along the circumferential direction of the fixed seat. The movable seat has an abutting end surface abutting against the plug-in end surface, and the multiple slots are recessed on the abutting end surface.

[0008] As a further improvement of the present invention, the notch of the slot has a guiding slope that gradually narrows toward the depth direction of the slot.

[0009] As a further improvement of the present invention, the movable seat includes a cylindrical seat body which is coaxially arranged with the fixed seat and spaced apart from the fixed seat; the multiple wire loops are sleeved on the seat body and located between the fixed seat and the seat body; along the extension direction of the slot, the peripheral wall of the movable seat is provided with a plurality of open grooves connected with the slot, and the open grooves are evenly distributed around the central axis of the movable seat; the elastic conductive member includes a plurality of contacts, each of the contact is located in the corresponding open groove, and the contact is used to electrically connect the terminal with the corresponding wire loop.

[0010] As a further improvement of the present invention, the movable seat further comprises a limiting portion formed by folding outward from the end side of the seat body, and the diameter of the limiting portion is greater than the diameter of the seat body.

[0011] As a further improvement of the present invention, the male end component is provided with a hook portion, and after the terminal is inserted into the slot, the hook portion is hooked onto the limiting portion.

[0014] As a further improvement of the present invention, the female end component is connected to the door body.

[0015] Compared with the plug-in terminal structure in the prior art, the terminal block in the present invention does not have an anti-foolproof structure. When the installer plugs the male end component with the female end component, it is only necessary to insert the terminal post on the male end component into the slot of any one of the female end components. The expansion and contraction amount of the elastic conductive part can be adjusted by the protruding length of the terminal post, so that the elastic conductive part is electrically connected to the wire loop at the corresponding position, thereby electrically connecting the terminal post to the corresponding wire loop through the elastic conductive part. There is no need to plug the terminal post and the slot one by one, thereby reducing the installation difficulty of the terminal block and enabling blind plugging. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0026] It should be understood that the terms used herein, such as "upper", "lower", "inner", "front", etc., indicating spatial relative positions are used for the purpose of convenience to describe the relationship of one component or feature relative to another component or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0027] See also Figures 1 to 9As shown, the present invention provides a terminal 100 including a male end component 1 and a female end component 2. Specifically, the male end component 1 includes a base 11 and a plurality of terminals 12 protruding from the base 11. The base 11 has a plug-in end surface 13. The plurality of terminals 12 are evenly arranged on the plug-in end surface 13 around the center of the plug-in end surface 13, and the plurality of terminals 12 have different protruding lengths.

[0028] Furthermore, the female end component 2 includes a plurality of slots 21 for inserting the terminal 12, each of the slots 21 is provided with an elastic conductive member 22 that docks with the terminal 12, and the female end component 2 also includes a plurality of wire loops 23 spaced apart along the extension direction of the slots 21, and the elastic conductive member 22 is used to electrically connect the wire loop 23 with the corresponding terminal 12. Compared with the terminal structure in the prior art, the terminal 100 in the present invention does not have an anti-foolproof structure. When the installer blindly plugs the terminal 100, he only needs to rotate the male end component 1 to insert the terminal post 12 on the male end component 1 into the slot 21 of any female end component 2. The extension and contraction amount of the elastic conductive member 22 can be adjusted by the protruding length of the terminal post 12, so that the elastic conductive member 22 is electrically connected to the wire loop 23 at the corresponding position, thereby electrically connecting the terminal post 12 to the corresponding wire loop 23. The terminal 100 in the present invention does not require the terminal post 12 and the slot 21 to be plugged in one by one, thereby reducing the installation difficulty of the terminal 100 and easily realizing blind plugging.

[0029] It can be understood that the number of the terminal 12, the slot 21, the elastic conductive member 22 and the wire loop 23 is the same, and the position of the slot 21 on the female end part 2 corresponds to the position of the terminal 12 on the male end part 1. Specifically, when a terminal 12 is inserted into any slot 21, the remaining terminals 12 correspond to the positions of the remaining slots 21, so that one terminal 12 can correspond to any slot 21.

[0030] Furthermore, the protruding length of each terminal 12 is different, so that the terminal 12 is electrically connected to the corresponding wire loop 23. Specifically, when the terminal 12 on the male end part 1 is inserted into the slot 21, the end of the terminal 12 away from the plug-in end face 13 abuts against the elastic conductive member 22, and the terminal 12 is electrically connected to the elastic conductive member 22. As the depth of the terminal 12 inserted into the slot 21 increases, the terminal 12 pushes the elastic conductive member 22 to gradually move in the direction of the notch away from the slot 21 until the elastic conductive member 22 is in a preset position, so that the elastic conductive member 22 is electrically connected to the wire loop 23 at the corresponding position, thereby realizing the electrical connection between the terminal 12 and the corresponding wire loop 23. It is known that the slot 21 includes a notch and a slot bottom, the notch is the side close to the male end part 1, and the slot bottom is the side away from the male end part 1.

[0031] It can be understood that the position of each wire loop 23 is corresponding to the preset position of the terminal 12 that needs to be connected to the wire loop 23 to push the elastic conductive member 22. Thus, the terminal 12 and the corresponding wire loop 23 are connected. The electrical connection in the present invention can be considered as the transmission of electricity between the male end component 1 and the female end component 2, and of course, it can also be a signal transmission.

[0032] In one embodiment of the present invention, refer to Figure 5 As shown, there are three terminals 12 on the male end part 1, and the three terminals 12 are evenly arranged on the plug-in end face 13 around the center of the plug-in end face 13, and the three terminals 12 have different protruding lengths. Specifically, the terminals 12 include a first terminal 121 and a second terminal 122 for power connection, and a third terminal 123 for signal transmission, and the first terminal 121 has a first preset protruding length, the second terminal 122 has a second preset protruding length, and the third terminal 123 has a third preset protruding length, and the first preset protruding length> the second preset protruding length> the third preset protruding length, then along the extension direction of the slot 21, the first wire loop 231 correspondingly connected to the first terminal 121 is located on a side away from the notch of the slot 21, the third wire loop 233 correspondingly connected to the third terminal 123 is located on a side close to the notch of the slot 21, and the second wire loop 232 correspondingly connected to the second terminal 122 is located between the first wire loop 231 and the third wire loop 233.

[0033] Furthermore, a pin 24 is provided on the side of the notch of the elastic conductive part 22 close to the slot 21, and an alignment groove 14 cooperating with the pin 24 is provided on the side of the terminal 12 away from the plug-in end face 13, or an alignment groove is provided on the side of the notch of the elastic conductive part 22 close to the slot 21, and a pin cooperating with the alignment groove is provided on the side of the terminal 12 away from the plug-in end face 13, thereby increasing the reliability of the connection between the terminal 12 and the elastic conductive part 22.

[0034] Furthermore, the female end component 2 also includes a cylindrical fixed seat 25 and a movable seat 26 connected to the fixed seat 25 along the circumferential direction of the fixed seat 25. Therefore, when installing the terminal 100, the male end component 1 can remain in position and adjust the position of the slot 21 by rotating the movable seat 26 so that the terminal 12 can be quickly inserted into the slot 21.

[0035] Furthermore, the movable seat 26 has an abutting end face 27 that abuts against the plug-in end face 13, and the multiple slots 21 are recessed on the abutting end face 27. The abutting end face 27 on the female end component 2 abuts against the plug-in end face 13 to limit the depth of the terminal 12 inserted into the slot 21, thereby avoiding excessive compression of the elastic conductive part 22 and ensuring that the elastic conductive part 22 is in a preset position, thereby ensuring that the terminal 12 is connected to the corresponding wire loop 23.

[0036] Further, see Figure 4 As shown, the notch of the slot 21 has a guiding slope 28 which gradually narrows toward the depth direction of the slot 21 , thereby guiding the terminal 12 to enter the slot 21 , so that the male end component 1 and the female end component 2 can be quickly plugged in.

[0037] Specifically, see Figure 6 As shown, the movable seat 26 includes a cylindrical seat body 261 which is coaxially arranged with the fixed seat 25 and spaced apart from the fixed seat 25; the multiple wire loops are sleeved on the seat body 261 and located between the fixed seat 25 and the seat body 261, so that the overall structure of the female end component 2 is compact and occupies little space.

[0038] Along the extension direction of the slot 21, a plurality of opening slots 29 communicating with the slot 21 are provided on the peripheral wall of the movable seat 26, and the opening slots 29 are evenly distributed around the central axis of the movable seat 26. The elastic conductive member 22 includes a plurality of contacts 223, each of which is located in a corresponding opening slot 29, and the contacts 223 are used to electrically connect the terminal 12 with the corresponding wire ring 23.

[0039] The movable seat 26 also includes a limiting portion 262 folded outward from the end side of the seat body 261, and the diameter of the limiting portion 262 is larger than the diameter of the seat body 261. Specifically, limiting portions 262 are provided at both ends of the seat body 261 to prevent the movable seat 26 from shaking along the extension direction of the slot 21, thereby ensuring the position accuracy of the movable seat 26 relative to the fixed seat 25.

[0040] Further, see Fig. 9 As shown, the elastic conductive member 22 includes an elastic portion 221 connected to the bottom of the slot 21, a conductive portion 222 connected to the elastic portion 221 on one side of the slot opening close to the slot 21, and a contact 223 protruding from the outer periphery of the conductive portion 222. Each of the contacts 223 is movably connected to the corresponding open slot 29. When the terminal 12 abuts against the conductive portion 222, the contact 223 moves along the open slot 29 until the contact 223 is electrically connected to the wire loop 23.

[0041] It can be understood that the position of the opening slot 29 corresponds to the contact 223 , and the number of the opening slot 29 is the same as the number of the contact 223 .

[0042] In a specific embodiment of the present invention, the wire loop 23 is a circular metal ring. When the terminal 12 abuts against the conductive portion 222, the contact 223 moves along the opening groove 29 until the contact 223 abuts against the inner wall of the circular metal ring, thereby connecting the terminal 12 with the corresponding wire loop 23.

[0043] Furthermore, a hook portion 15 is also provided on the male end component 1 in the present invention. After the male end component 1 and the female end component 2 are plugged in, the hook portion 15 is hooked onto an end face of a limiting portion 262 having an abutting end face 27, thereby improving the stability of the connection between the male end component 1 and the female end component 2.

[0044] The present invention also provides a refrigeration device, which includes a box body and a door body for opening and closing the box body. The refrigeration device also includes a first wiring harness 200 led out from the box body and a second wiring harness 300 to be introduced into the door body. The refrigeration device electrically connects the first wiring harness 200 and the second wiring harness 300 through a wiring terminal 100, wherein the specific structure of the wiring terminal 100 is the same as described above and will not be repeated here.

[0045] Furthermore, the female end part 2 of the terminal block 100 is connected to the door body, and the fixing seat 25 is provided with a connecting portion 251 connected to the door body, so that the female end part 2 is fixedly connected to the door body. The terminal block 100 inserts the male end part 1 into the female end part 2 to realize the wiring between the box body and the door body. In addition, there is no connecting wire inside the female end part 2 in the present invention, which avoids the problem of the connection wire being easily broken due to the movement of the door body in the prior art.

[0046] The terminal block 100 in the invention does not have an anti-foolproof structure. When the installer blindly plugs the terminal block 100, he only needs to rotate the male end component 1 so that the terminal post 12 on the male end component 1 is inserted into the slot 21 of any female end component 2. The extension and contraction amount of the elastic conductive member 22 can be adjusted by the protruding length of the terminal post 12, so that the elastic conductive member 22 is electrically connected to the wire loop 23 at the corresponding position, thereby electrically connecting the terminal post 12 to the corresponding wire loop 23. The terminal block 100 in the present invention does not need to plug the terminal post 12 and the slot 21 one by one, thereby reducing the installation difficulty of the terminal block 100 and easily realizing blind plugging.
