Description

Technical Field

[0001] This utility model relates to connectors, and more particularly to a key socket, a keying assembly, and a connector. Background Technology

[0002] Variable displacement connectors typically achieve positioning through the engagement of keyways and grooves. However, variable displacement connectors require multiple rotations, often necessitating a corresponding plug and socket for each rotation. Since the external shapes of the plugs and sockets are similar, matching them can be difficult, leading to mis-insertion during the mating process and consequently affecting the connector's mating performance. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a key socket, a key rotation component, and a connector.

[0004] The purpose of this utility model is achieved through the following technical solution: a key seat, including a cylindrical body, a plurality of protruding teeth are provided on the outer edge of the cylindrical body, the protruding teeth are evenly distributed along the circumferential direction, a tooth groove is formed between adjacent protruding teeth, and the end face of the protruding teeth is flush with the end face of the cylindrical body, an arc-shaped mating notch is provided on the end face of the cylindrical body away from the protruding teeth, and an arc-shaped mating protrusion is formed on the cylindrical body.

[0005] An indexing assembly includes a key seat, a housing, a tail nut, and a mounting plate. The housing has a raised key, the size of which matches the tooth groove. The mounting plate has an outwardly protruding limiting ring with an axially formed keyway. The key seat is fitted onto the mounting plate, with its end face fitting against the end face of the limiting ring. The mounting plate is fitted inside the housing, with the raised key located within the corresponding tooth groove. A tail nut is installed at the tail end of the housing, and an inwardly protruding limiting ring is provided at the tail end of the tail nut. The tail end of the mounting plate abuts against the limiting ring.

[0006] A connector includes a plug and a socket, which are mated together. The plug and socket each have a repositioning assembly at their mating ends. A socket assembly is mounted in the mounting plate of the repositioning assembly of the plug, and a pin assembly is mounted in the mounting plate of the repositioning assembly of the socket. When the plug and socket are mated, the socket assembly and the pin assembly are mated together. An arc-shaped mating protrusion on the socket is inserted into an arc-shaped mating notch on the plug, and the arc-shaped mating protrusion on the socket and the arc-shaped mating part on the plug form a ring structure.

[0007] Optionally, the arc-shaped convex part has a semi-circular structure.

[0008] The present invention has the following advantages: The connector of the present invention has a key seat installed inside the housing, and the cooperation between the protruding teeth on the key seat and the protruding key on the housing realizes multiple rotations. Moreover, the addition of the key seat increases the creepage distance between the contact and the housing, making the product more reliable. In addition, the key seat is provided with arc-shaped mating protrusions. After the plug and socket are inserted, the two arc-shaped mating protrusions can form a ring structure. Therefore, if the plug and socket do not match, the plug and socket cannot be inserted, thereby avoiding misinsertion of the connector. Attached Figure Description

[0016] like Figure 1 As shown, a connector includes a plug 100 and a socket 200, which are mated together. Both the plug 100 and the socket 200 have a rotation component at their mating ends. In this embodiment, as shown... Figure 2 As shown, the indexing assembly includes a key seat 20, a housing 10, a tail nut 40, and a mounting plate 30. For the indexing assembly on the plug 100, its housing 10 is the plug 100 housing 10; for the indexing assembly on the socket 200, its housing 10 is the socket 200 housing 10. In this embodiment, as... Figure 5 As shown, the key seat 20 includes a cylindrical body 21. A plurality of protruding teeth 22 are formed on the outer edge of the cylindrical body 21. The protruding teeth 22 are evenly distributed along the circumferential direction, and grooves are formed between adjacent protruding teeth 22. The end faces of the protruding teeth 22 are flush with the end faces of the cylindrical body 21. An arc-shaped mating notch 23 is formed on the end face of the cylindrical body 21 away from the protruding teeth 22, and an arc-shaped mating protrusion 24 is formed on the cylindrical body 21. In this embodiment, as shown... Figure 2 , Figure 3 and Figure 4As shown, a key is provided on the housing 10, the size of which matches the tooth groove. An outwardly protruding limiting ring is provided on the mounting plate 30, and a keyway is axially formed on the limiting ring. The key seat 20 is fitted onto the mounting plate 30, and the end face of the key seat 20 is in contact with the end face of the limiting ring. The mounting plate 30 is fitted inside the housing 10, and the key is located within the corresponding tooth groove. A tail nut 40 is installed at the tail end of the housing 10, and an inwardly protruding limiting ring is provided at the tail of the tail nut 40. The tail end of the mounting plate 30 abuts against the limiting ring. During installation, the key seat 20 is first fitted onto the mounting plate 30, and then the mounting plate 30 is inserted into the housing 10 from the tail end. A limiting step is provided inside the housing 10. When the key tooth 22 and... After the limiting step abuts, it indicates that the mounting plate 30 is installed in place. Then, the tail nut 40 is installed at the tail of the housing 10. Of course, an external thread is provided on the outer circle of the tail of the housing 10. When the tail nut 40 is tightened, the tail of the mounting plate 30 abuts against the limiting protrusion ring. Under the action of the limiting step and the limiting protrusion ring, the mounting plate 30 will not move axially. Furthermore, the length of the protrusion key is greater than the length of the tooth groove. Therefore, part of the protrusion key will be located in the keyway on the limiting ring, so that the mounting plate 30 and the housing 10 can be positioned during installation. Moreover, after the mounting plate 30 is installed, it will not rotate circumferentially relative to the housing 10, thereby ensuring the reliability of the installation of the mounting plate 30.

[0017] In this embodiment, as Figure 1 As shown, a socket assembly is installed inside the mounting plate 30 of the plug 100's repositioning assembly, and a pin assembly is installed inside the mounting plate 30 of the socket 200's repositioning assembly. When the plug 100 and socket 200 are plugged in, as... Figure 6 As shown, the socket assembly and the pin assembly are inserted, and the arc-shaped mating protrusion 24 on the socket 200 is inserted into the arc-shaped mating notch 23 of the plug 100. The arc-shaped mating protrusion 24 on the socket 200 and the arc-shaped mating portion on the plug 100 form a ring-shaped structure. Preferably, the arc-shaped mating protrusion 24 is a semi-circular structure. Therefore, when the plug 100 and the socket 200 are inserted, the insertion area of ​​the pin assembly and the plug 100 assembly is located within the cavity formed by the two key seats 20, thereby effectively protecting the installation area. The contacts (pin assembly or socket assembly) within the board 30, and the presence of the key seat 20 increases the creepage distance of the connector, thus enhancing its electrical performance. Furthermore, the key seat 20 has several protrusions 22, which can be rotated according to actual needs during installation. After rotation, if the two key seats 20 do not match when the plug 100 and socket 200 are inserted, the plug 100 and socket 200 cannot be inserted, thereby avoiding the adverse effects caused by misinsertion of the plug 100 and socket 200.

[0018] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
