Detailed Description

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

The invention will be described in detail below with reference to the drawings in connection with embodiments.

Example 1:

as shown in fig. 1, the present embodiment provides a connector assembly 1, which mainly includes a single connector 2, a receiving member 3, a connecting member 8 and a nut 15, wherein one end of the receiving member 3 is in threaded connection with the single connector 2, the other end is connected with the connecting member 8, and the nut 15 is in threaded connection with the connecting member 8. When the connector assembly is assembled, the nut 15 rotates relative to the receiver 3 when the nut 15 is disassembled because the threaded connection strength between the nut 15 and the connecting piece 8 is smaller than the threaded connection strength between the Yu Nazi and the single connector 2, and the receiver 3 and the single connector 2 still remain fastened.

Specifically, as shown in fig. 2 and 3, the single joint 2 is a hollow tubular structure as a whole, and one end thereof is provided with external threads for connection. The middle part of the single joint 2 is provided with a positioning boss for being abutted with the end part of the receiver 3 for positioning.

The nanometer 3 comprises a first end 4 and a second end 5, the first end 4 is provided with a first connecting hole 6, and the hole wall of the first connecting hole 6 is provided with internal threads. The second end 5 is provided with a second connecting hole 7, the cross-sectional shape of the second connecting hole 7 being polygonal. The first connecting hole 6 and the second connecting hole 7 are provided with a baffle 13, and the baffle 13 is provided with a through hole for communicating the first connecting hole 6 and the second connecting hole 7. In this embodiment, the cross-sectional shape of the second connection hole 7 is hexagonal, and in other embodiments, may be triangular or other polygonal.

Referring to fig. 3, the connecting member 8 is a hollow tubular structure, and includes a connecting end 9, and the connecting end 9 is a polygonal prism structure; the present embodiment is a hexagonal prism structure that mates with the second connection hole 7 of the nano-meter 3. The other end of the connecting piece 8 is of a columnar structure, and external threads are arranged on the columnar structure; the external thread is intended to cooperate with a nut 15.

With continued reference to fig. 3, when the connector assembly 1 is assembled, the hexagonal prism structure of the connecting member 8 may be first installed into the second connection hole 7 of the receiver 3; and the nut 15 is connected with external threads on the connecting piece 8; then the first connecting hole 6 of the nano-rod 3 is connected with the external thread of the single joint 2; finally, the nut 15 is screwed down, and the nut 15 transmits torque to the nano-meter 3 through the connecting piece 8, so that the nano-meter 3 and the single joint 2 are fastened. Since the screw connection strength of the nut 15 and the connecting member 8 is smaller than the screw connection strength of the Yu Nazi 3 and the single connector 2, the nut 15 is unscrewed so that the nano-meter 3 is not detached from the single connector 2.

The beneficial effects of the connector assembly that this embodiment provided are as follows:

after fastening the nano-3 with the single joint 2, the nut 15 can be selectively removed; at this time, since the screw connection strength between the nut 15 and the connector 8 is smaller than the screw connection strength between the Yu Nazi 3 and the single connector 2, the receiver 3 is not detached from the single connector 2 when the nut 15 is detached. Further, since the reverse torque cannot be applied to the stator 3, the connector assembly 1 can be prevented from being detached.

It should be noted that, in other embodiments, the single joint 2 may be provided with an internal thread, and the nano-element 3 is correspondingly provided with an external thread; alternatively, in other embodiments, the nut 15 may be omitted, and during assembly, a part of the hexagonal prism structure of the connecting piece 8 is first installed into the second connecting hole 7, torque is applied to the exposed part of the hexagonal prism structure by using a tool, and after the nano-rod 3 is fastened to the single joint 2, the whole hexagonal prism structure is pushed into the second connecting hole 7; or the nut 15 is not limited to the hexagonal prism structure, and may be other structures, for example, an irregular structure including internal threads, as long as torque can be applied to the nut 15 conveniently.

Example 2:

the present embodiment provides a connector assembly substantially similar to that of embodiment 1, except that the connecting member 8 retains only the connecting end 9, i.e., retains only the hexagonal prism structure on which the lugs 10 are disposed; in addition, a groove for cooperation with the lug 10 is provided on the inner wall of the second connection hole 7 of the receptacle.

Specifically, as shown in fig. 5 and 6, the connecting piece 8 is integrally in a hexagonal prism structure, and a sheet-shaped support lug 10 is arranged on the outer wall of the connecting piece, and the support lug 10 extends perpendicular to the outer wall; and are symmetrically arranged about the axis of the hexagonal prism. Because the lugs 10 are sheet-shaped, when the lugs 10 receive a force in the axial direction, the lugs 10 can be folded to a position to be attached to the outer wall.

With continued reference to fig. 5 and 6, a first accommodating groove 11 and a second accommodating groove 12 which are mutually communicated are provided on the inner wall of the second connecting hole 7 of the nano-element 3; the first accommodating groove 11 and the second accommodating groove 12 each extend along the axial direction of the second receptacle 3, and the depth of the first accommodating groove 11 is greater than the depth of the second accommodating groove 12. The first accommodating groove 11 and the second accommodating groove 12 have different depths, so that the communicating positions of the two grooves form a table-shaped structure; the table-shaped structure is provided with a chamfer to form a slope.

If 7 and 8, the hexagonal prism structure of the connection member 8 is pushed into the second connection hole 7 when the connector assembly is assembled, and stopped when the lugs 10 are abutted with the mesa structure. At this time, since the support lugs 10 are disposed in the middle of the hexagonal prism structure of the connector 8, the hexagonal prism structure also exposes a portion, and at this time, torque is applied to the exposed portion by a tool, and the hexagonal prism structure transfers the torque to the nano-element 3, thereby fastening the nano-element 3 with the single connector 2. Finally, applying axial force to the hexagonal prism structure, and bending and attaching the support lugs 10 to the outer wall of the hexagonal prism structure under force; the axial force continues to be applied and the lugs 10 are pushed into the second receiving grooves 12 until the entire hexagonal prism structure of the connecting piece 8 is pushed into the second connecting hole 7.

after the hexagonal prism structure of the connector 8 is integrally pushed into the second connection hole 7, since a reverse torque cannot be applied to the nano-meter 3, the connector assembly 1 can be prevented from being disassembled.

Example 3:

the present embodiment provides a connector assembly assembling method that can be used to assemble the connector assembly of embodiment 2; the method comprises the following steps:

a. the nano-3 is in threaded connection with the single joint 2;

b. part of the connecting end 9 of the connecting piece 8 is installed in the polygonal hole of the receiver 3 until the supporting lug 10 is abutted with the boss structure in the second connecting hole 7; applying torque to the connection 8, thereby transmitting torque to the receptacle 3 through the connection 8; and then the nano-3 is screwed with the single joint 2. After tightening, the connection terminal 9 is integrally fitted into the second connection hole 7.

The assembling method of the connector assembly provided by the embodiment has the following beneficial effects:

It should be noted that the above method is not limited to the order of the steps, and the order of the steps may be appropriately adjusted in the case where final assembly is possible.

Example 4:

the present embodiment provides an air conditioner including the connector assembly of embodiments 1, 2 or other modified embodiments.

The air conditioner provided in this embodiment has the following beneficial effects:

the air conditioner adopts the connector assembly capable of preventing disassembly, so that the leakage of refrigerant at the joint caused by disassembly of the connector assembly can be prevented when the air conditioner is used for connecting an evaporation pipe and a connecting pipe.
